▼ Proprotein Convertase Subtilisin / Kexin Type-9 (PCSK9) has emerged as a major regulator of plasma cholesterol levels. PCSK9 is secreted mainly from the liver and circulates as a plasma protein. PCSK9 binds cell surface low-density lipoprotein (LDL) receptors and mediates their degradation upon endocytosis in the liver. This decreases the liver’s ability to clear LDL-cholesterol from the blood. PCSK9 is also capable of binding LDL particles themselves; this interaction inhibits the ability of PCSK9 to bind and mediate LDLR degradation in cultured hepatic cells, but its effect on PCSK9 function in vivo remains unknown. A disordered N-terminal region of the PCSK9 prodomain is necessary for binding to isolated LDL particles in vitro. This N-terminal region is also autoinhibitory to PCSK9-LDL receptor binding. We hypothesized that the N-terminal of the PCSK9 prodomain plays a role in an allosteric mechanism that regulates PCSK9 function. Through mutagenesis studies, we found that both a conserved stretch of acidic residues and an adjacent conserved stretch of hydrophobic residues are crucial for the PCSK9-LDL interaction; the hydrophobicity of the residue at position 38 (Tyr) within the conserved acidic stretch was also found to be important for this. Helical wheel modeling of the prodomain N-terminal sequence revealed the potential for a lipid-ordered amphipathic helix to form, which may aid PCSK9 docking onto LDL. Replacing residues A44 and L41 with helix-disrupting proline residues abolished LDL binding. Co-pelleting ultracentrifugation assays also show that wild-type PCSK9 is capable of associating with liposomes, while the A44P mutation disrupts this lipid association. The A44P-PCSK9 mutation, showing an 80-90% decrease in LDL association but with LDL receptor binding and degrading functions intact, may serve as an important tool in future studies investigating the PCSK9-LDL interaction in vivo. Elucidation of the mechanism by which LDL-binding naturally inhibits PCSK9 activity may also help to develop new anti-PCSK9 therapeutics in the future.

▼ Cholesterol is an essential mammalian membrane component. In mammalian cells, cholesterol homeostasis needs to be tightly regulated since the aberrant intracellular cholesterol transport and storage are associated with many human diseases, including cardiovascular disease, Alzheimers disease, as well as a rare inherited neurodegenerative disorder, Niemann-Pick disease type C (NPC). One crucial cholesterol regulatory pathway involves endosomal sorting of low density lipoprotein (LDL)-derived cholesterol to the endoplasmic reticulum (ER), where cholesterol levels are sensed to exert a feedback regulation. However, the exact mechanisms underlying the transport of LDL-derived cholesterol from late endosome/lysosome (LE/Ly) to the ER remain unclear. This project identifies Hrs and Vps4 as novel regulators of endosomal cholesterol transport. Being part of, or associated with, the endosomal sorting complex required for transport (ESCRT) machinery, Hrs and Vps4 are two important proteins involved in the endosomal multivesicular body formation pathway. In this project, we show in HeLa cells that depletion of Hrs or Vps4 by RNAi results in cholesterol accumulation in LE/Ly, a cellular phenotype reminiscent of NPC disease caused by mutations in either NPC1 or NPC2 proteins. Endosomal transport of LDL-derived cholesterol to the ER is blocked in Vps4 knockdown or Hrs knockdown cells. Interestingly, the expression and localisation of NPC1 and NPC2 are not compromised upon Vps4 depletion. Other ESCRT subunits, including Tsg101 (ESCRT-I), EAP20 (ESCRT-II) and all ESCRT-III components investigated in this project do not have similar effects to those of Vps4 and Hrs, suggesting a novel role of these two ESCRT-associated molecules in endosomal cholesterol trafficking. This study provides mechanistic insights into how cholesterol is sorted out of LE/Ly, which may help understand the pathogenesis of cholesterol metabolism-related diseases.

▼ Abstract: Background/Objectives: Plasma level of low-density lipoprotein
cholesterol (
LDL-C) has become a major marker and the central preventive target for cardiovascular disease in a large spectrum of clinical settings. However, recent reports have raised questions about the consistency of this concept in individuals aged of 80 years or older. Hence, the aim of this study was to evaluate in a carefully selected population if the association between lipid parameters and coronary atherosclerotic burden remains significant. Design, Setting, Participants, Measurements: Individuals aged of 80 years or older (n=208) who spontaneously sought primary prevention care and have never manifested cardiovascular disease, malnutrition, neoplastic or consumptive disease were enrolled for a cross-sectional analysis. Medical evaluation, anthropometric measurements, blood tests and cardiac computed tomography were obtained. Results: 1- In analyses adjusted for age, gender, diabetes, systolic and diastolic blood pressure, smoking and statin therapy no association was found between coronary calcium score (CCS) and
LDL-C (1.79 (0.75-4.29)). There was no association between TG and CCS. The association between HDL-C and CCS was significant and robust in unadjusted (0.32 (0.15-0.67)) as well as in the fully adjusted analysis (0.34 (0.15-0.75)). Results: 2-All the coronary segments (>3.000) were assessed to the presence of coronary atherosclerotic plaques. Coronary atherosclerotic plaques by CCTA were classified according to previous studies: positive remodeling (PR), not calcified plaques (NCP) and spotty calcification (SC). Individuals were categorized in the presence or absence of PR, NCP and SC and highest and lowest to the last quartile of the lipid profile (HDL-C (? 63 vs < 63mg/Dl),
LDL-C ? 138 vs < 138 mg/dL, TG (?156 vs <156 mg/dL)). Results-In adjusted analysis by age, gender, body fat, hypertension, creatinine, CRP, diabetes mellitus, smoking, physical activity and use of statin all type of plaques with instability phenotype were associated with age. No association was found between LDL_C or TG and atherosclerotic plaques. Association remains between remodeling plaques and HDL-C< 63 mg/dL in fully adjusted model (2.5(1.1,-6.3);0.040) Conclusion: The present study confirms in a healthy cohort of individuals aged of 80 years or more that while the association between
LDL cholesterol and coronary atherosclerosis weakens with aging, the opposite occurs with the levels of HDL
cholesterol

▼ Introdução: O Diabetes mellitus (DM) está associado a complicações crônicas micro e macrovasculares. A medida da hemoglobina glicada (HbA1c) avalia o grau do controle glicêmico em pacientes diabéticos e seus níveis são capazes de prognosticar o risco de desenvolvimento dessas complicações. Entre as origens das complicações causadas pela hiperglicemia, há a hipótese dos produtos finais de glicação avançada (AGEs) e do estresse oxidativo. A reação de glicação não enzimática das proteínas também está relacionada com as complicações diabéticas e é responsável pela formação da HbA1c. Entretanto, tem sido demonstrado um aumento dessa glicação em pacientes não diabéticos. Um dos prováveis mecanismos para esse aumento é a peroxidação lipídica, com conseqüente aumento nos níveis de malondialdeído (MDA) que modifica a apolipoproteína B (APO B) do colesterol de baixa densidade (
LDL). A modificação oxidativa do
LDL confere propriedades específicas pró-aterogênicas. A presença do
LDL oxidado e o aumento da tendência do
LDL à peroxidação lipídica, podem contribuir para o aumento dos níveis de HbA1c. Objetivo: Verificar a associação entre os níveis de HbA1c com o Colesterol
LDL e
LDL oxidado em Indivíduos não-diabéticos. Métodos: Foi realizado um estudo transversal observacional, no qual um total de 196 indivíduos, classificados como não-diabéticos, foram analisados e divididos em três grupos, conforme os valores de HbA1c e glicemia de jejum (GJ): Grupo 1 (n =64) - HbA1c <5,7% e GJ <100 mg/dL; Grupo 2 (n =69) - HbA1c ≥5,7 e ≤6,4% e GJ <100 mg/dL; Grupo 3 (n =63) - HbA1c ≥5,7 e ≤6,4% e GJ ≥100 e <126mg/dL. Amostras de sangue total e soro foram coletadas. O
LDL oxidado foi medido por método imunoensaio enzimático (Mercodia ®), ApoB dosada por imunoturbidimentria, a relação Colesterol
LDL(oxi)/Colesterol-HDL foi estimada, além das outras dosagens bioquímicas do perfil lipídico. Esses testes foram comparados e analisados entre os três diferentes grupos. Resultados: Houve diferença significativa nos níveis de
LDL(oxi) (p< 0,001), Apo B (p= 0,026) e razão
LDL(oxi)/HDL (p< 0,001) entre os três grupos. Os valores de HbA1c apresentaram correlação positiva com os valores de
LDL (oxi) (r =0,431; p <0,001),
LDL (r =0,148; p =0,039), Col Não-HDL (r =0,192; p =0,007) e Apo B (r =0,171; p <0,001). Estas associações positivas permaneceram significativas, mesmo após ajuste, por análise de regressão linear múltipla para as variáveis álcool, medicamentos, índice de massa corporal (IMC) e idade. Também apresentaram correlações positivas com os valores de HbA1c: razão
LDL (oxi)/HDL (r =0,422; p <0,001), CT (r =0,142; p =0,048), triglicerídios (r =0,155; p =0,030) e IMC (r =0,263; p <0,001). Conclusão: Nosso estudo demonstrou associação dos níveis de HbA1c com as partículas lipídicas aterogênicas
LDL, Apo B, colesterol não HDL e
LDL (oxi). Os níveis de
LDL, principalmente
LDL (oxi), estão significativamente associados com os níveis de HbA1c e glicose, mesmo em indivíduos não-diabéticos. Os indivíduos classificados com alto risco de desenvolver DM ou…

▼ L'athérosclérose est une complication cardiovasculaire majeure des maladies liées à une augmentation du stress oxydatif, comme le diabète de type 2 et le syndrome métabolique. Dans ces situations, les lipoprotéines de faible densité (LDL) subissent une oxydation et leur forte absorption induit une accumulation de cholestérol dans les macrophages sous-endothéliaux. D'autre part, les LDL oxydées sont enrichies en produits d'oxydation du cholestérol appelés oxystérols, dont certains sont impliqués dans la capacité des LDL oxydées à induire un stress oxydant cellulaire et une cytotoxicité, principalement par apoptose. Le Bis(Monoacylglycéro)Phosphate (BMP) est un phospholipide unique, localisé préférentiellement dans les endosomes tardifs, compartiment cellulaire clef dans le métabolisme du cholestérol dérivé des LDL. Lors de travaux antérieurs, l'équipe a démontré le rôle prépondérant du BMP dans la régulation de l'homéostasie du cholestérol dans les macrophages. L'objectif de ce travail a été de décrypter les mécanismes moléculaires intervenant dans le trafic intracellulaire du cholestérol. Ainsi, le BMP régule l'efflux de cholestérol par les HDL (high density lipoproteins) grâce à des mécanismes impliquant les LXRs (liver X receptors) et les transporteurs ABCA1/ABCG1 (ATP binding cassette-type A1/G1). De plus, notre étude indique que le BMP exerce également un rôle protecteur contre l'effet pro-apoptotique des LDL oxydées via la réduction de la production intracellulaire d'oxystérols. Comme une partie du trafic intracellulaire des stérols au sein des macrophages est régulé par OSBP (oxysterol binding protein) et ses protéines dérivées, les ORPs (OSBP-related proteins), nous montrons dans ce rapport que l'action de protection du BMP contre les effets cytotoxiques des oxystérols est fortement diminuée dans des cellules où la protéine ORP11 est supprimée, suggérant que le BMP exerce son rôle protecteur via un mécanisme utilisant la fonction d'ORP11 dans le transport intracellulaire de stérols
Atherosclerosis is a major cardiovascular complication in increased oxidative stress-related diseases such as type 2 diabetes and metabolic syndrome. In these situations, the low density lipoproteins (LDL) undergo oxidation and their high uptake induces cholesterol accumulation in subendothelial macrophages. On the other hand, oxidized LDL are enriched in cholesterol oxidation products called oxysterols, some of them are involved in the ability of oxidized LDL to induce cellular oxidative stress and cytotoxicity, mainly by apoptosis. Bis(Monoacylglycero)Phosphate (BMP) is a unique phospholipid localized preferentially in late endosomes, a central cellular compartment of LDL-cholesterol metabolism. In previous work, the team demonstrated the leading role of BMP in regulation of cholesterol homeostasis in macrophages. The aim of this work was to characterize the molecular mechanisms involved in the intracellular trafficking of cholesterol. Thus, BMP regulates cholesterol efflux to HDL (high density lipoproteins) by mechanisms…

▼ Odkąd odkryto, że PCSK9 (ang. Proprotein
Convertase Subtilisin/Kexin type 9) degraduje
receptory
LDL, stało się ono jednym z głównych
obiektów badań nad miażdżycą.
Celem niniejszej pracy było określenie udziału
białka PCSK9 w patogenezie miażdżycy u 102 osób
z ostrym zespołem wieńcowym (OZW), przed i po
sześciomiesięcznym leczeniu statynami
(40mg/dzień) oraz określenie wpływu wyciszenia
ekspresji genu PCSK9 na ekspresję PCSK9 i LDLR.
Analiza grupy badanej wykazała
podwyższony poziom białka PCSK9 w osoczu oraz
obniżony poziom transkryptu LDLR i gęstości białka
receptora
LDL w porównaniu do kontroli. Terapia
statynami spowodowała istotny wzrost mRNA LDLR
oraz poziomu białka receptorowego na monocytach,
ale także nasiliła transkrypcję PCSK9.
Sekwencjonowanie genu PCSK9 ujawniło
obecność dwóch polimorfizmów. Obecność A53V
nie wiązało się z ryzykiem rozwoju miażdżycy. Z
kolei w przypadku E670G potwierdzono związek
z wysokim poziomem cholesterolu we krwi.
Udowodniono, że zastosowanie odpowiednich konstruktów siRNA wycisza ekspresję
PCSK9 w komórkach HepG2, co skutkuje wzrostem
gęstości receptorów
LDL na powierzchni komórek.
Podsumowując, białko PCSK9 uczestniczy w
rozwoju miażdżycy u osób z OZW poprzez
zmniejszenie ilości receptorów
LDL na powierzchni
komórek. Wykorzystanie statyn aktywuje ekspresję
LDLR oraz PCSK9, dlatego włączenie do terapii
inhibitora ekspresji PCSK9 mogłoby poprawić
efektywność leczenia choroby niedokrwiennej serca.

▼ Background: Increasing sugars intakes has been linked to an increased risk of cardiovascular disease such as diabetes, insulin resistance and obesity. When sugars are consumed in excess of energy requirements and glycogen storage capacity they are converted to lipids in the liver and stored as fat. This also results in an increase in circulating lipid concentrations in the blood. The aim of this thesis was to determine whether there is a relationship between consumption of dietary sugars and blood lipids as a biomarker of cardiovascular risk.
Design: Systematic review and meta-analysis of randomised controlled trials (RCTs) following the Cochrane Collaboration guidelines including and using Cochrane meta-analysis software Revman 5.0.
Data sources: Four article databases (OVID Medline, Scopus, Embase and CINAHL) were searched for randomised controlled trials published before April 2012. Grey literature sources and references lists of review articles were also searched.
Study selection: We included randomised controlled trials from 1960 to the present, where dietary sugars intake was increased in one arm of the study in comparison with another and which reported effects on one of the following outcome measures; triglycerides, HDL,
LDL or total
cholesterol. Participants were healthy subjects who were not affected by a metabolism-altering disease and were not undergoing any acute treatment for disease.
Data synthesis: Mean pooled effects of higher versus lower sugars intakes on lipid outcome measures were estimated using inverse variance models of analysis with random effects to account for heterogeneity. Subgroup analyses further examined the effects of study length, study type, provision of intervention, type of intervention, type of control group, weight loss and diabetes on the association between sugars intake and lipids.
Results: 17,020 potentially relevant studies were identified by electronic searches. 35 studies remained after deduplication and exclusion of studies that did not meet the inclusion criteria. 873 participants participating in 10 parallel trials and 25 crossover trials were included. Higher compared with lower sugars intakes was associated with raised triglycerides (0.13mmol/L [95% confidence interval (CI) = 0.07, 0.20]),
LDL cholesterol (0.20mmol/L [95% CI = 0.07, 0.33]) and total
cholesterol (0.07mmol/L [95% CI = 0.03, 0.10]). There was no significant association with HDL
cholesterol. Weight increase in those with a high dietary sugar intake was associated with a significant decrease in total
cholesterol in contrast with no weight change, which was associated with an increase in total
cholesterol. The effects of sugars in lipids were strengthened in crossover trials, those trials where dietary intake was isoenergetic and in interventions where sugars were exchanged for complex carbohydrates rather than other simple carbohydrates. Accounting for potential bias attenuated the findings somewhat.
Conclusions: This meta-analysis provides evidence that high dietary sugars intake is…

▼ Rationale: Risk factors for cardiovascular disease (CVD) are both modifiable and non-modifiable. Modifiable risk factors associated with CVD poor diet quality, physical inactivity and tobacco consumption. Individuals with familial hypercholesterolemia (FH) have inherited genetic disorders affecting low-density lipoprotein receptors. These individuals are predisposed to a greater risk of CVD due to increased low-density lipoprotein
cholesterol (
LDL-C) levels. Dietary modifications remain an important part of CVD risk reduction in FH.
Methods: This study was a pre and post intervention design that ran over eight weeks. We recruited FH participants through GP practices in Dunedin and Southland. Dietary assessment for each participant was carried out using a prompted 24-hour recall and a semi-quantitative FFQ. The FFQ was used to create a simulated 7-day diet record for each participant. This was done at baseline and repeated at the end of the study. Nutrient analyses of diets were done using Kai-culator©. Blood lipids were compared pre and post intervention. The blood lipid measurements were taken for total
cholesterol (TC), high density lipoprotein
cholesterol (HDL-C),
LDL-C, triglycerides (TAG), and TC:HDL ratio. Spearman’s correlations and paired t-tests were carried out to determining changes in nutrient intakes and their associations with lipid changes.
Results: No significant differences were found between pre and post mean levels of TC, HDL-C,
LDL-C, TAG or TC:HDL-C. There were significant reductions in intakes of biscuits (p=0.002), eggs and egg dishes (p=0.027), bread based dishes (p=0.012) and processed meat (p=0.008). There were also significant increases in intakes of fish and seafood (p=0.003), nuts (p=0.002),fruit (p=0.012), and vegetables (p=0.016) and table spread (p=0.048). This related to a significant reduction in intakes of saturated fatty acids (p<0.001),
cholesterol (p=0.003) and an increase in monounsaturated (p=0.01) and polyunsaturated fatty acids (p=0.035). Qualitative feedback indicated that the majority of participants found the study to be helpful in increasing their understanding of heart healthy eating habits, and in changing their dietary practices.
Conclusions: This short term intervention showed that tailored dietary advice was effective in changing nutrient and food group intakes towards a more optimal diet. This study was limited due to the small sample size (n=25) and short study duration.

▼ The purpose of this study was to resolve a critical gap in depression literature through assessment of the temporal relationship between depression and low
LDL. A systematic review and meta-analysis was conducted to investigate the overall cross-sectional association between serum
LDL and depression. Inconsistent findings suggest that more work must be done to clarify the link between
LDL and depression. Next, Cox regression was used to explore the association between
LDL and the subsequent onset of depressive symptoms within a subset of the Women’s Health Initiative cohort and evaluate the potential for effect modification by lipid-lowering medication use. This study provides evidence toward an association between low
LDL and the subsequent onset of depressive symptoms, with increased risk confined to
LDL below 100 mg/dL. Elevated risk was not associated with lipid-lowering medication use. The final study examined the differences in the magnitude and direction of change in serum
LDL levels among individuals experiencing new-onset depression, and examines the potential for physical activity, energy intake, and total body weight to mediate the depression-
LDL relationship. This study provides no evidence of an association between depression and subsequent serum
LDL changes. Altogether, this data suggests that
LDL that is below 100 mg/dL without the use of lipid-lowering medication may predispose individuals to a greater risk of depression, and also suggests that low
LDL is not likely a state brought about by physiological or behavioral changes following the onset of depression.

▼ Elevated plasma cholesterol is a risk factor for cardiovascular disease. Proprotein convertase subtilisin/kexin type 9 (PCSK9) hinders the uptake of low-density lipoprotein cholesterol (LDL-c) by mediating degradation of LDL receptors (LDLRs) in the liver. Gain-of-function (GOF) mutations in PCSK9 cause familial hypercholesterolemia (FH). In normolipidemic human plasma, 30-40% of PCSK9 is bound to LDL particles, and this association with LDL inhibits PCSK9’s ability to mediate LDLR degradation in cultured cells. To further investigate the physiological relevance of this interaction, we analyzed natural GOF mutations in PCSK9 and assessed their effects in vitro on LDL binding, LDLR binding and LDLR degradation. Our results indicate that several GOF mutations severely inhibit LDL binding compared to wild type (WT) PCSK9, and only modestly affect LDLR affinity and LDLR degradation. These findings shed light on the potential physiological relevance of the PCSK9-LDL interaction, which may have an inhibitory effect on PCSK9 activity in vivo.

▼ Cardiovascular disease (CVD) is the leading cause of death in the United States. Medical practitioners and public health officials alike consider atherosclerosis, in which plaque buildup leads to the hardening of arteries, to be one of the main culprits in CVD morbidity and mortality. Measuring low-density lipoprotein
cholesterol (
LDL-C) has been touted as an effective proxy for assessing the risk for atherosclerosis. However, new emerging evidence show that traditional lipid biomarkers, such as
LDL-C, may not be as robust in CVD prediction as previously thought. Apolipoproteins, which are involved in the creation of lipoproteins, have been shown to be effective predictors of CVD events, even more so than
LDL-C in some cases, but previous research have also established a non-linear trend with apolipoprotein B (ApoB) distribution when age is involved. Therefore, in light of past research, this study aims to examine potential differential associations between ApoB,
LDL-C, and cardiovascular risk factors in the context of age groups. Using the 2013-2014 cycle of the National Health and Nutrition Examination Survey, we observed Spearman correlations and Wilcoxon/Kruskal-Wallis scores between various CVD risk factors (e.g.: body mass index, hypertension, diabetes status, etc.) and ApoB and
LDL-C across two age cohorts. We found that ApoB has a special relationship with the younger cohort that does not manifest with
LDL-C, and that this relationship attenuates in the older cohort. Based off of these results along with previous studies, assessment of CVD risk among the young would benefit from including ApoB in the already established battery of biomarkers.

▼ Cardiovascular disease (CVD) is one of the leading causes of death in the developingworld, killing one Australian every twelve minutes (www.heartfoundation.com.au).Hypercholesterolemia and long term elevated LDL-cholesterol (LDL-C) levels arelinked to the formation of atherosclerotic plaques, which can eventually lead tomyocardial infarction or stroke. It is therefore essential to lower LDL-C levels in orderto reduce cardiovascular (CV) risk.The low density lipoprotein receptor (LDLR) removes and degrades LDL particlesfrom circulation. Proprotein convertase subtilisin kexin type 9 (PCSK9) regulatescholesterol metabolism by degrading the LDLR. A number of pharmaceuticalcompanies have created therapeutic agents known as PCSK9 inhibitors, which bind toand block PCSK9. PCSK9 inhibitors in combination with existing lipid loweringtreatments have been shown to significantly decrease circulating LDL-C levels in awide variety of subjects. The aim of thesis was to examine the biology of PCSK9 insubjects with familial hypercholesterolemia (FH), in subjects at high CV risk and insubjects treated with a CETP inhibitor.The ex vivo and in vitro studies in this thesis demonstrated that statins increased,recombinant PCSK9 decreased, and the PCSK9 inhibitor restored LDLR cell surfaceexpression in all heFH and receptor defective hoFH subjects. However, LDLR cellsurface expression was not affected in receptor negative hoFH subjects. In subjects athigh CV risk the administration of ascending atorvastatin doses increased plasmaPCSK9 levels at each individual dose. Subjects with diabetes who were treated withatorvastatin also had significantly higher plasma PCSK9 levels compared to subjectswithout diabetes. However, the administration of the CETP inhibitor, torcetrapib hadno effect on circulating PCSK9 levels in subjects with or without diabetes.These results from this thesis provided a novel insight into PCSK9 biology and haveimportant clinical implications for subjects diagnosed with FH and in subjects at highCV risk. The results from these studies support current clinical trial results and providestrong in vitro and ex vivo evidence for the use of PCSK9 inhibitors in all heFH,receptor defective hoFH and statin treated subjects at high CV risk with or withouttype 2 diabetes.

▼ Os múltiplos constituintes salivares podem ser utilizados como biomarcadores
de doenças e condições sistémicas do indivíduo. A natureza não invasiva da
colheita da saliva é atrativa como método alternativo ao usado para o sangue.
Alguns analitos são difíceis de detetar devido à sua baixa concentração na
saliva. Este estudo tem como objetivo avaliar a correlação entre os níveis de
PCR de alta sensibilidade (asPCR), Colesterol total, Colesterol
LDL, Colesterol
HDL, Triglicerídeos, Ácido Úrico e Ureia em amostras de saliva e sangue,
assegurando a reprodutibilidade dos métodos.
Participaram neste estudo 42 indivíduos saudáveis (21 do sexo masculino e 21
do sexo feminino). As metodologias utilizadas foram: o método enzimático
colorimétrico (colesterol total, colesterol
LDL, colesterol HDL, triglicerídeos e
ácido úrico), método UV cinético (ureia) e nefelometria (asPCR).
Os valores de concentração do colesterol total, colesterol
LDL, colesterol HDL,
triglicerídeos e asPCR foram inferiores ao limite de deteção do método. Na
determinação quantitativa do ácido úrico e ureia observaram-se diferenças
estatisticamente significativas (p<0,05), entre o soro e a saliva. A concentração
de ácido úrico obtida na saliva resultou numa mediana 2,0 (Percentil 25-75;
1,2-2,4) mg/dL, sendo inferior à verificada no soro, 4,7 (4,0-5,2) mg/dL.
Contrariamente, a concentração da ureia na saliva, com mediana de 35 (27-48)
mg/dL, foi superior à verificada no soro 28 (26-32) mg/dL. Obteve-se uma
correlação positiva fraca no ácido úrico (rs=0,16) e ureia (r2=0,40) , entre a
saliva e o soro.
O uso da saliva como meio de diagnóstico, é promissora para aplicação clínica,
podendo este estudo contribuir para este propósito, juntamente com outros
com maior numero de amostras, com valores de referência e curvas de
calibração adaptados e que simultaneamente garantam a reprodutibilidade dos
métodos.

▼ Purpose: To determine the relationship between uric acid and lipid levels for the purpose of understanding more about the public health issue of Metabolic Syndrome. Methods: A retrospective analysis was conducted using 66 patients from a family health clinic who were over the age of 18 and who had been given at least three prescriptions of allopurinol. Repeated measures linear growth models with Restricted Maximum Likelihood tests were conducted to determine the relationship of uric acid and the lipid levels. Results: A significant relationship between uric acid and lipid levels was not determined. There was a slight indication of a relationship between uric acid and total
cholesterol or HDL-
cholesterol. Uric acid levels did not decrease over time for all participants as expected. Conclusions: More research is needed to explore the relationship between uric acid and lipid levels. Furthermore, compliance among participants could be enhanced by determining best health education methods.

▼ A determinação de Intervalos de Referência (IR) é uma árdua tarefa para os laboratórios clínicos, porém indispensável e de fundamental importância para a tomada de decisão médica. Para parâmetros como os lípides séricos, os IR tem sido estabelecidos consensos nacionais ou internacionais definindo limites de decisão (CLSI, 2008). O objetivo deste estudo foi determinar os IR para colesterol total, HDL-colesterol, colesterol não-HDL,
LDL- colesterol e triglicérides séricos em crianças e adolescentes saudáveis do município de Cuiabá, capital do estado de Mato Grosso. Trata-se de um estudo transversal, descritivo, realizado em 1.866 crianças e adolescentes saudáveis de creches e escolas municipais desta capital, obtidas por amostragem aleatória. Foi aplicado um questionário avaliando antecedentes do indivíduo e de seus familiares além de dados demográficos e antropométricos. Foram definidos como critérios de inclusão do estudo, crianças e adolescentes nas faixas etárias de 1 a 12 anos 11 meses e 29 dias, sem nenhuma doença de base diagnosticada ou queixas clínicas no momento da coleta. Além disto, os participantes não deveriam fazer uso regular de medicamento. As amostras foram coletadas em jejum. As amostras foram processadas no equipamento cobas® 6000 (analyser series - Roche Diagnostics), em laboratório da rede DASA na cidade de Cuiabá. Em relação à metodologia estatística, foi analisada a homogeneidade das variâncias através do teste de Bartlett para cada analito por idade e, posteriormente, testados pelo teste ANOVA ou Kruskal-Wallis para verificar a existência de diferença entre as faixas etárias. O teste \"post hocd̈e Bonferroni foi aplicado quando se constatou a diferença para reagrupar as faixas etárias similares, constituindo assim novos grupos etários. Aplicou-se então, o teste de Bartlett e, conforme seu resultado, realizou-se ANOVA ou Kruskal-Wallis para verificar se os agrupamentos nas faixas se mantinham. Em seguida, procedeu-se a exclusão de valores extremos (outiliers) tomados como sendo aqueles valores acima ou abaixo da média ± 3 desvios-padrão. Depois de excluídos os outiliers, obteve-se o IR como sendo a média ± 2 desvios-padrão dos valores remanescentes. Adicionalmente, foi calculada a distribuição em percentis, sendo adotado o critério do NHLBI 2012 como proposta de limite de decisão para a população estudada. Em todos os testes, o nível de significância adotado foi de 5%. As análises estatísticas foram realizadas pelos programas MINITAB (versão 15) e SPSS (versão 16). Este projeto foi aprovado pelas Comitês de Ética em Pesquisa das instituições envolvidas e das Secretarias Municipais de Educação e Saúde de Cuiabá. Os valores encontrados para o colesterol total, nos percentis 75 e 95 foram: 1 a 2 anos de 160 mg/dL e 189 mg/dL; 3 a 8 anos de 170 mg/dL e 199 mg/dL; 9 a 12 anos de 176 mg/dL e 205 mg/dL, respectivamente. Para o colesterol não-HDL, na única faixa etária de 1 a 12 anos, os valores nestes percentis foram de 122 mg/dL e 150 mg/dL, respectivamente. Para o
LDL-colesterol, os valores…

▼ Estudos anteriores em nosso laboratório demonstraram que pacientes portadores de DAC apresentam diferenças no metabolismo do CL e CE de uma nanoemulsão artificial rica em colesterol (LDE), nos quais o CL apresentou maior remoção plasmática e depósito arterial. Dando continuidade a esta linha de pesquisa, neste trabalho foram avaliadas a cinética plasmática, representada pela taxa fracional de remoção (TFR), e a captação do 3H-colesterol livre (3H - CL) e 14C - colesterol esterificado (14C - CE) da LDE por segmentos arteriais e por órgãos de coelhos normais (n=17) e coelhos submetidos à indução de aterosclerose por dieta rica em colesterol (1%) (n=13). Além disso, avaliou-se a captação in vitro do 3H CL e do 14C CE da LDE por células endoteliais aórticas de coelhos. Por último, foi avaliada a influência da inibição da enzima lecitina-colesterol aciltransferase (LCAT), e indiretamente, a esterificação do CL em ratos normais (n=9) e tratados com diazepam (n=9). Em coelhos que receberam dieta normal, não houve diferença entre a remoção plasmática do 3H - CL e do 14C - CE. Em coelhos que desenvolveram hiperlipidemia e aterosclerose através de dieta rica em colesterol, o 3H - CL foi removido mais rapidamente da circulação do que o 14C - CE (p<0,05), entretanto houve maior captação de 14C - CE do que de 3H - CL no arco aórtico (p<0,05). Em ambos os grupos, os principais órgãos captadores de colesterol da LDE foram fígado, pulmão, adrenais e baço (p<0,05). Tanto a TRF quanto a captação hepática de 3H - CL e 14C - CE foram menores no grupo que recebeu a dieta rica em colesterol. Em células endoteliais aórticas de coelhos, a captação de 3H - CL foi maior que a de 14C CE independente da massa de LDE incubada (p<0,01). Em ratos, não houve diferença entre a captação das duas formas de colesterol da LDE pela aorta no grupo controle, entretanto, quando a atividade da LCAT foi diminuída pelo tratamento com diazepam, a captação arterial de 3H - CL foi maior do que a de 14C - CE (p< 0,01). A hiperlipidemia e distúrbios no processo de estabilização do colesterol, favorecem a dissociação entre o CL e o CE das lipoproteínas, e podem elevar o risco de desenvolvimento da aterosclerose, assim como agravar o processo de aterogênese.
I n previously studies, it was shown that free cholesterol (FC) and cholesterol ester (CE) of a cholesterol-rich nanoemulsion (LDE) behaves differently in patients with coronary artery disease (CAD). The FC plasma clearance and arterial deposition is greater than CE. In the present study we evaluate the plasma kinetics, estimated by the fractional clearance rate (FCR), and the tissue uptake of 3H-free cholesterol (3H FC) and of 14C cholesterol ester (14C - CE) of LDE by arterial segments and organs of rabbits with (n=13) and without atherosclerosis (n=17). Furthermore, it was evaluated the in vitro uptake of 3H FC and 14C - CE by rabbit aortic endothelial cells. Finally, it was evaluated the inhibition of the enzyme lecithin-cholesterol acyltransferase (LCAT), and indirectly, the FC esterification in…

▼ As doenças crônicas, como diabetes, doenças cardiovasculares (DCV) e câncer, representam atualmente 60% de todas as mortes no mundo. O estresse oxidativo, desencadeado pela ação de radicais livres, está envolvido na patogênese de inúmeras doenças crônicas, a exemplo as DCV. Alguns nutrientes presentes em frutas e verduras possuem ação antioxidante, como é o caso dos flavonóides e da vitamina C, e seu consumo regular está associado à diminuição do risco de desenvolvimento de doenças crônicas. O camu-camu [Myrciaria dubia (Kunth) McVaugh] é um fruto exclusivo da região amazônica que possui teores significativos de antioxidantes, principalmente vitamina C e flavonóides. O presente trabalho teve como objetivo avaliar o efeito do pó da polpa de camu-camu sobre a glicemia e o perfil lipídico de adultos jovens. A polpa do camu-camu foi liofilizada e sua composição nutricional foi analisada utilizando-se os métodos indicados pelo Instituto Adolpho Lutz para a composição centesimal e o método de CLAE para vitamina C. Para a intervenção, foi conduzido um ensaio clínico controlado, duplo-cego, em 18 voluntários de ambos os gêneros, com idades entre 21 e 35 anos. Os participantes foram divididos em dois grupos: 1) grupo intervenção, que recebeu cápsulas de camu-camu liofilizado contendo 320 mg de vitamina C; 2) grupo controle, que recebeu cápsulas contendo 320 mg vitamina C sintética. A ingestão das cápsulas foi diária durante 15 dias e duas coletas de sangue foram procedidas, uma antes do início do estudo e outra ao final. Foram verificadas as diferenças estatísticas nos níveis de vitamina C no plasma, glicemia de jejum e perfil lipídico por meio do Teste t de Student. O camu-camu liofilizado apresentou 20.310 mg de vitamina C/100g e 12,89 mg de flavonóides/100g. Ao final da intervenção registrou-se queda significativa nos níveis de glicemia de jejum, colesterol total e HDL (p<0,05) no grupo que recebeu cápsulas de camu-camu e redução significativa apenas da glicemia de jejum (p<0,05) no grupo que recebeu cápsulas de vitamina C sintética. Quando avaliados somente aqueles indivíduos que seguiram corretamente o protocolo, observou-se diminuição significativa também nos valores de LDL (p<0,05) no grupo intervenção. Em ambos os grupos houve tendência de redução nos níveis de triglicerídeos, porém não significativa (p>0,05). Conclui-se que as cápsulas de camu-camu foram mais eficientes, apresentando ação hipolipidêmica e hipoglicemiante nos voluntários estudados. Tais resultados demonstram o potencial benéfico da vitamina C e do camu-camu à saúde, apresentando o fruto como uma excelente fonte desta vitamina.
Currently, chronic diseases such as diabetes, cardiovascular disease (CVD) and cancer account for 60% of all deaths worldwide. Oxidative stress caused by the action of free radicals is involved in the pathogenesis of many chronic diseases such as CVD. Flavonoids and vitamin C are antioxidant nutrients found in fruits and vegetables, and its regular consumption is associated with decreased risk of developing chronic diseases.…

▼ Objetivo: comparar o perfil lipídico de em crianças e adolescentes, com e sem inflamação, atendidas num pronto atendimento geral de pediatria de um hospital universitário de nível de atendimento secundário, segundo estado nutricional, sexo e idade. Métodos: Estudo transversal, realizado entre outubro de 2012 e agosto de 2013, avaliou 124 crianças e adolescentes (3 meses a 14 anos de idade) em atendimento na unidade de emergência do Hospital Universitário da Universidade de São Paulo, com queixa relacionada a processo inflamatório/infeccioso. Os pacientes foram separados em dois grupos de acordo com os níveis de proteína C reativa (PCR): grupo I se maior ou igual a 5 mg/L, e grupo II se menor que 5mg/L. Dosagens de colesterol total, lipoproteína de alta densidade (HDL) e baixa densidade (LDL), triglicerídeos e albumina foram comparadas entre os dois grupos, levando em conta o estado nutricional (avaliado através de medidas antropométricas), gênero e idade. Resultado: A mediana de idade foi de 51 meses, com maioria dos pacientes classificados como eutróficos (76,5%). Do total da amostra, 34,7% dos pacientes apresentaram colesterol total e/ou triglicerídeos alterados e 67% apresentaram baixos níveis de HDL. Não houve diferença significativa do perfil lipídico entre os dois grupos de pacientes separados de acordo com PCR. Dentre os pacientes com PCR >= 5mg/L, a PCR apresentou correlação inversa com HDL [r= (-)0,363 e p=0,001], com LDL [r= (-) 0,235 e p=0,034], com albumina [r= (-) 0,308 e p=0,005] e correlação direta com TG (r=0,426 e p > 0,001). Na analise de regressão linear, se evidenciou que para cada aumento de 1mg/L nos valores da PCR espera-se uma redução média de 0,072 mg/dL da HDL, de 0,083 mg/dL da LDL, de 0,002g/dL de albumina, e um aumento médio de 0,564 mg/dL do triglicerídeo. Conclusão: Pacientes com processo inflamatório apresentam alterações nos níveis séricos do HDL, LDL e triglicerídeos que se relacionam com o grau de inflamação, de forma independente do estado nutricional
Aim: To compare the lipid profile in children and adolescents with and without inflammation, met a ready general pediatric service of a university hospital secondary care level, according to nutritional status, gender and age. Methods: Cross-sectional study conducted between October 2012 and August 2013, assessed 124 children and adolescents (3 months to 14 years old) in the emergency department of the University Hospital of the University of São Paulo, with reports of inflammatory/ infectious process. The patients were divided into two groups according to the C reactive protein (CRP) levels: group I is higher than or equal to 5 mg/L, and Group II was lower than 5 mg/L. Total cholesterol, high density lipoprotein (HDL) and low density lipoprotein (LDL), triglycerides and albumin were compared between the two groups, taking into account the nutritional status (assessed by anthropometric measurements), gender and age. Results: The median age was 51 months, with patients mostly classified as well-nourished (76.5%). Of the overall…

▼ Treinamento físico é considerado um dos principais instrumentos para promover um estilo de vida saudável. No entanto, os efeitos do treinamento resistido sobre as vias metabólicas, especialmente o metabolismo lipídico intravascular é em grande parte inexplorada e merece uma investigação mais aprofundada. No presente estudo nós avaliamos os efeitos do treinamento resistido sobre o metabolismo de uma nanoemulsão artificial lipídica e na transferência de lípides para HDL, uma importante etapa do metabolismo da HDL. A cinética plasmática da nanoemulsão artificial lipídica foi estudada em 15 homens saudáveis com treinamento resistido regular de 1-4 anos (idade = 25 ± 5 anos, VO2máx = 50 ± 6 mL/kg/min) e em 15 homens saudáveis sedentários (28 ± 7 anos, VO2máx = 35 ± 9 mL/kg/min). A nanoemulsão artificial lipídica marcada com éster de colesterol-14C e colesterol livre-3H foi injetada por via intravenosa, as amostras de plasma foram coletadas por 24 h para determinar curvas de cinéticas e a taxa fracional de remoção (TFR). Transferência de lípides para HDL foi determinada in vitro pela incubação de amostras de plasma com nanoemulsões (doadores de lípides) marcada com o isótopo radioativo colesterol livre, éster de colesterol, triglicérides e fosfolípides. Tamanho da HDL, atividade da paraoxonase 1 e os níveis de LDL oxidada também foram determinadas. Os dois grupos apresentaram LDL-colesterol, HDL-colesterol e triglicérides semelhantes, mas a LDL oxidada foi menor no grupo treinamento resistido (30 ± 9 vs 61 ± 19 U/L, p = 0,0005). No treinamento resistido, a nanoemulsão éster de colesterol-14C foi removida duas vezes mais rápido do que em indivíduos sedentários (TFR: 0,068 ± 0,023 vs 0,037 ± 0,028, p = 0,002), bem como o colesterol livre-3H (0,041 ± 0,025 vs 0,022 ± 0,023, p = 0,04). Embora ambos os componentes da nanoemulsão tenham sido removidos na mesma proporção em indivíduos sedentários, no grupo treinamento resistido o colesterol livre-3H foi removido mais lento do que o éster de colesterol-14C (p = 0,005). Tamanho da HDL, paraoxonase 1 e as taxas de transferência de HDL dos quatro lipídios foram as mesmas em ambos os grupos. Portanto, concluímos que o treinamento resistido acelera a remoção da nanoemulsão artificial lipídica, o que provavelmente explica a redução dos níveis de LDL oxidada no grupo treinamento resistido. O treinamento resistido também alterou o equilíbrio da TFR do colesterol livre e esterificado. No entanto, o treinamento resistido não teve efeito nos parâmetros relacionados ao metabolismo da HDL
Exercise training is considered one of the main instruments to promote a healthy lifestyle. However, effects resistance training on the metabolic pathways, specially the intravascular lipid metabolism is largely unexplored and deserves further investigation. In this study we evaluated the effects of resistance training on the metabolism of an LDL-like nanoemulsion and on lipid transfer to HDL, an important step of HDL metabolism. LDL-like nanoemulsion plasma kinetics was studied in 15 healthy men under…

▼ INTRODUÇÃO: portadores de diabetes mellitus tipo 1 (DM1) apresentam, progressivamente, complicações vásculo-neurais. Os fatores que aumentam o risco de coronariopatia - hipertensão, dislipidemia e idade avançada - explicam, em parte, a alta mortalidade cardiovascular, entretanto diabéticos tipo 1 podem morrer de coronariopatia precoce e não apresentar os fatores de risco clássicos para aterosclerose. Modificações estruturais e funcionais nas lipoproteínas, alterando a sua composição e trocas lipídicas poderiam justificar o aumento de eventos vasculares, entretanto estas alterações podem não ser detectadas através das dosagens rotineiras de lípides plasmáticos. OBJETIVOS: através de nanoemulsão lipídica artificial (LDE) que simula a estrutura lipídica da
LDL avaliamos, em portadores de DM1, normolipidêmicos, intensivamente tratados e sem complicações significativas da doença, a taxa de esterificação do colesterol, a remoção da nanoemulsão da circulação, o tamanho da partícula HDL e as transferências de lípides entre a nanoemulsão e as partículas HDL. Secundariamente, determinamos a influência do controle glicêmico, resistência à insulina (RI) e insulinização no metabolismo lipídico. MÉTODOS: estudamos 36 indivíduos diabéticos e 37 controles não-diabéticos pareados para idade, sexo e índice de massa corpórea. Nanoemulsão lipídica artificial com marcação radioativa nos lípides éster de colesterol (CE), colesterol livre (CL), triglicérides (TG) e fosfolípides (PL) foi utilizada para os estudos. Nanoemulsão com marcação 14C-CE e 3H-CL foi injetada nos participantes e amostras de sangue foram coletadas durante 24 horas para mensuração da radioatividade. Remoção dos lípides da circulação foi calculada por análise compartimental. A taxa da esterificação do colesterol livre foi calculada após extração e separação de lípides do plasma por cromatografia em camada delgada. Para estudo da transferência de lípides, nanoemulsões com marcação 14C-CE e 3H-CL ou 14C-PL e 3H-TG foram incubadas com plasma e a radioatividade dos lípides transferidos para as HDL foi contada após a precipitação de lipoproteínas contendo apoB. O diâmetro da HDL foi mensurado por método de dispersão da luz. A RI nos diabéticos foi mensurada por fórmula que estima a taxa de captação da glicose. RESULTADOS: hemoglobina glicada foi de 8,8±1,3 mg/dl e concentrações de LDLc foram menores nos diabéticos (85±22 vs. 98±26 mg/dl), p=0, 035. Não houve diferenças em relação às taxas de esterificação, transferências de lípides da nanoemulsão para as HDL e tamanho da partícula HDL entre os grupos. Não encontramos relação entre as análises cinéticas e HbA1c, glicemia, índices de RI e dose de insulina. A taxa de remoção do 14C-CE foi mais rápida em diabéticos tipo 1 que nos controles (0, 059±0, 022 vs.0, 039±0, 022 h-1), p=0, 019. 16 CONCLUSÕES: apesar de controle glicêmico ruim nos DM1, as transferências de lípides da nanoemulsão para as HDL, a taxa de esterificação e a remoção da 3H-CL são semelhantes às dos controles. O controle glicêmico, perfil lipídico, índices de RI…

▼ Abstract
Increased plasma cholesterol is a well-known risk factor for cardiovascular diseases in middle and early old age. At older ages, this association seems to disappear. Very few studies have assessed the impact of the lifelong cholesterol burden on old age, the purpose of this thesis. Study populations consisted of 1) old persons with familial hypercholesterolemia (FH), a genetic disorder associated with an increased risk of coronary heart disease (CHD) if untreated, and 2) initially healthy men (The Helsinki Businessmen Study, HBS) followed-up from midlife to old age.
A population-based FH cohort, aged ≥ 65 years (n=37, aged 65 to 84 years) agreed to participate in this study. All but one of them had been using statin therapy for approx. 15 years. Variables studied were: health-related quality of life (HRQoL) with questionnaires (RAND-36, 15D), a brain magnetic resonance imaging (MRI) scan and cognitive tests (CERAD).
These older FH patients enjoyed a similar HRQoL as controls in the general population. Only two (6%) of the older FH patients had clinically silent brain infarcts detected by MRI and those aged 65 to 74 years did not have more white matter hyperintensities (WMHIs) when compared to middle-aged controls. In the cognitive assessments, FH patients, especially those with duration of statin therapy longer than median, even expressed better episodic memory than population controls.
HBS consists of a cohort of men (3277 men) who at baseline (1964–1973) were healthy and in their 40s. They were subdivided into seven groups according to baseline total cholesterol value at 1 mmol/L intervals starting from ≤ 4 mmol/L. In 2000, at a mean age of 73 years, they filled a postal questionnaire including RAND-36. Cumulative mortality data were collected up to January 2010. A strong and graded relation was found between the cholesterol level and total mortality, those men with a cholesterol level ≤ 4 mmol/L exhibiting the lowest mortality. A low cholesterol value at midlife also predicted a better score in the Physical functioning scale of RAND-36 in old age.
In conclusion, in initially healthy men, a low cholesterol value at midlife was associated with better survival and better physical function in old age. Despite their genetic risk, FH patients on long-term statin medication seemed to enjoy a health and cognitive status similar to the general population.
Tiivistelmä
Suurentunut plasman kolesterolipitoisuus on tunnettu valtimotautien riskitekijä keski-iässä, mutta vanhuusiässä kolesterolin merkitys näyttää vähentyvän. Hyvin harvassa tutkimuksessa on tutkittu elämänaikaisen kolesterolitason vaikutuksia vanhuusiän terveydentilaan, kuten tässä väitöskirjatyössä. Tutkimuskohteina olivat 1) iäkkäät, joilla on familiaalinen hyperkolesterolemia (FH) eli perinnöllinen sairaus, johon hoitamattomana liittyy lisääntynyt sepelvaltimotaudin riski, sekä 2) alun perin terveet miehet (Helsingin Johtajatutkimus), joita seurattiin keski-iästä vanhuuteen.

▼ Background. The published reports of the effectiveness of simvastatin in treatment of hypercholesterolemia were mostly conducted in western populations, and only few studies in Asian or domestic populations have ever been reported. By regulations from Bureau of National Health Insurance, the effective dosage of lipid lowering agents should be started from lower dose, such as 20 mg of simvastatin per day. Whether this dosage of simvastatin is effective for treatment of patients with hypercholesterolemia and the efficacy and safety of such dosage are the objects of this study.
Materials and Methods. After the approval of IRB in a medical center located at north Taiwan, a randomized 12-week study was conducted to evaluate the efficacy and safety of 20mg/day simvastatin treatment on hypercholesterolemia. By randomization 65 patients, followed up at cardiovascular outpatient department under the diagnosis of primary hypercholesterolemia, were enrolled into a 4-week washout period, and finally 49 intent-to-treat patients entered a 12-week treatment with 20mg simvastatin per day, given through oral routine in the evening. Demographic and laboratory data were obtained before and after treatment. The primary efficacy measure was the changes from baseline in lipid parameters. Tolerability was assessed in terms of the overall incidence of adverse experiences and the most commonly reported adverse experiences.
Results. The per-protocol analyses included 39 hypercholesterolemic patients whom completed 12 weeks of therapy. Total
cholesterol and
LDL cholesterol at the end of the study period showed significant reductions by 22.5ï¼ (p<0.001) and 29.8ï¼(p<0.001), respectively. Triglyceride also showed a significant reduction by 31.8% (p=0.006), whereas total alkaline phosphatase and calcium showed a weak and insignificant change over the study period. The female group had significantly greater reduction in triglyceride than that in the male group, and the non-smoking group also had significantly greater reduction in triglyceride than that in smoking group after 12-week treatment. There were 17 studied cases (34.7%) had minor transient but clinical insignificant increases in serum aspartate aminotransferase and alanine aminotransferase, and 7 cases (14.3%) experienced symptom of painful muscle, of whom 3 cases (6.1%) dropped out this study.
Conclusion. Our results, although obtained from a small scale of hypercholesterolemic patients, suggest a probable positive efficacy and good tolerability with only few minor side effects of simvastatin on blood lipids.

▼ Background: Although intensive antiretroviral therapies dramatically reduce mortality rates in HIV-infected patients, significant metabolic complications associated with antiretroviral therapy including dyslipidemia have been increasingly reported. Objectives of this study are to determine 1) an effect of individual nutritional counseling on dyslipidemia, particularly LDL-C, among Thai HIV-infected adults with dyslipidemia who were not currently taking lipid-lowering medication 2) predictors of reducing LDL-C in Thai HIV-infected adults receiving a stable of antiretroviral regimen for at least 3 months. Methods: We conducted a randomized, 24-week study in HIV-infected patients who were on antiretroviral therapy with dyslipidemia and were eligible to initiate therapeutic lifestyle changes according to National Cholesterol Education Program (2002). Participants were randomly assigned into two groups. The intervention group received individual counseling with a nutritionist whereas the control group received general diet advice from a physician. A 24-hr recall technique was used to assess dietary intake for both groups at baseline and at week 24. Lipid profile was measured at baseline, at 12 weeks and 24 weeks of follow up. Predictors (measured at baseline) associated with the reduction of LDL-C in HIV-infected patients were assessed for any reduction in LDL-C and for a reduction of at least 10 mg/dL. Results: Seventy-two patients were randomly assigned. Of these, 62 (86%) completed lipid profile testing and 59 (82%) completed dietary interview. We found a significant difference in mean reduction from baseline of total cholesterol (8% vs 0%) and LDL-C (13% vs 4%) between the intervention group and the control group at week 24. A significant reduction in weight and in carbohydrate intake in the intervention group was observed. Participants who had good level of knowledge of dyslipidemia were more likely to achieve reduction in LDL-C of at least 10 mg/dL at 24 weeks of follow up. Conclusions: The effectiveness of individual nutritional counseling in improving dyslipidemia, particularly total cholesterol and LDL-C, among Thai HIV-infected adults with dyslipidemia receiving antiretroviral therapy has been demonstrated. To provide a better care for HIV-infected patients receiving antiretroviral therapy with hyperlipidemia, routine HIV/AIDS care with individualized nutritional counseling integration and adequate knowledge of dyslipidemia provision are recommended.

▼ <h1> </h1>
Foods incorporating plant sterols (PS) reduce Low-density lipoprotein (
LDL) on average approximately 10%. PS with a higher lipid solubility may promote greater reductions. We examined the
cholesterol lowering effect of a novel triglyceride recrystallized phystosterol (TRP). Twenty subjects (mean ± SD; age, 56 ± 10 years; BMI, 27 ± 5) with elevated
LDL (>100 mg/dL) participated in three 4-week phases; Phase I, 2% milk; Phase II, milk with 2.0 grams (g) free PS; Phase III, milk with 2.0 g TRP. Before and after each phase two fasting blood draws were obtained for determination of serum
cholesterol. Between the 2% and TRP milk phases total,
LDL and High-density lipoprotein (HDL)
cholesterol changed by -9.0% (p = .001), -11.0% (p = .002) and -8.0% (p = .029) respectively: between the free PS and TRP milk phases total,
LDL and HDL
cholesterol changed by -3.3% (p = .136), -2.3% (p = 1.00), -6.4% (p = .023) respectively. Apo B concentrations resulted in a decrease of -6.9% (p = .048) between the free PS and TRP milk phases and did not significantly change between the 2% and TRP milk phases. Triglycerides and Apo A1 concentrations did not significantly change between any of the phases. In conclusion, TRP can be effectively incorporated into a skim milk resulting in a significant
cholesterol lowering effect. (218 words)

▼ The liver is the largest internal organ of the human body and provides for a wide range of functions, which can be seriously compromised by toxic drugs and diseases. In order to develop novel and safer drugs, in vitro models of the human liver are increasingly adopted to complement drug screenings in animal models, known to have species-specific differences in liver pathways. Micropatterned co-cultures (MPCCs) of primary human hepatocytes (PHHs) and supportive 3T3-J2 murine embryonic fibroblasts maintain high levels of liver functions for several weeks in vitro and have been highly useful to screen for drug toxicity and mimic key mechanisms of liver diseases, such as non-alcoholic fatty liver disease (NAFLD), a condition that affects ~30% of patients in the US and is highly correlated to obesity. When culturing cells, bovine serum is commonly used; however, it is problematic given its variability and the mismatch of proteins across species. Nonetheless, avoiding the use of bovine serum in the cell culture medium results in reduced proliferation and number of fibroblasts, in turn causing a rapid decline in PHH functions. Therefore, in this thesis we firstly developed a novel animal serum-free culture medium by implementing low levels of both low density lipoproteins (
LDL) and high density lipoproteins (HDL), able to induce and maintain MPCC functions for several weeks towards significantly higher levels than the current serum-free medium formulation. Secondly, we tested the newly developed serum-free medium formulation for drug screening against MPCCs induced towards a NAFLD phenotype (steatosis and insulin resistance) using either a mixture of fatty acids found in the human diet or human serum, evaluating the efficacy of clinical drugs (2,4- dinitrophenol and pioglitazone) at non-toxic concentrations. Although unable to reduce hepatic steatosis, insulin sensitivity improved transiently, whereas steatotic PHHs spontaneously purged intracellular lipids irrespective of drug therapy upon removal of fatty acids from the culture, suggesting that diet restriction may be critical for alleviating NAFLD in patients. Ultimately, our model system together with the newly developed serum-free medium can prove useful for developing novel and safe drugs against liver diseases towards alleviating the disease burden on the human population.

▼ Coronary artery disease is the leading cause of death worldwide and results from progression of atherosclerosis, which is triggered in part by elevated plasma concentrations of LDL cholesterol. Genome-wide association studies have identified many loci that are associated with circulating lipid levels and bioinformatics tools have been implemented to prioritize positional candidate genes. This project aims to better understand the genetics underlying the regulation of plasma LDL levels and their effect of atherosclerosis using a zebrafish (Danio rerio) model system. A multiplex line with the genes abcg5, abcg8, myrf, col4a3bpa, col4a3bpb, st3gal3, ywhaqa and ywhaqb targeted by CRISPR/Cas9 technique was established using zebrafish with fluorescently labeled macrophages (Tg[mpeg1:mCherry]) and neutrophils (Tg[mpo:EGFP]). Monodansylpentane cadaverase was used to visualize lipids droplets, together with macrophages and neutrophils, in 384 overfed larvae, allowing the visualization and quantification of vascular atherogenic traits at 10 days post-fertilization. Euthanized larvae were homogenized for the quantification of triglycerides, total cholesterol, LDL, HDL, glucose and protein levels. DNA was extracted and larvae were paired-end sequenced for the CRISPR-targeted sites. Linear regression analysis to compare the wild-type larvae against homozygous mutants and additive models for orthologous genes were performed. The lower accumulation of lipids and the lower co-localization of macrophages and neutrophils in the vasculature suggested that the larvae with mutations in the gene abcg5, abcg8, col4a3bpb, and ywhaqb resulted in larvae more protected against atherosclerotic phenotype. The study suggested that loss of function of the targeted genes was associated with atherogenic traits, helping to understand the pathophysiology of atherosclerosis.

▼ Familiaalinen hyperkolesterolemia on dominantisti periytyvä LDL-reseptorin sairaus, joka johtaa plasman kohonneeseen LDL-kolesterolipitoisuuteen ja aiheuttaa hoitamattomana varhaista ateroskleroosia ja sepelvaltimotautia. Tauti on lapsuudessa usein oireeton ja alidiagnosoitu.
Tämän tutkielman tavoitteena oli tarkastella HYKS Lastenklinikalla vuosina 2013–2014 hoidettuja FH-potilaita ja selvittää miten jo diagnosoidut potilaat ovat päätyneet erikoissairaanhoidon piiriin. Tämä auttaa selvittämään nykykäytäntöjen toimivuutta ja sitä, mitä niissä voitaisiin parantaa. Toisena tavoitteena oli tutkia hoidon vaikutuksia ja hyötyä potilaille.
Aineisto koostui 76:sta FH-diagnoosin saaneesta lapsipotilaasta, joista enemmistö (63,2 %) oli tyttöjä. Tutkimus suoritettiin keräämällä tietoja sähköisistä sairaskertomuksista sekä HUS:n ja HUSLAB:n tietokannoista. Tutkimuksessa selvisi, että 75 % potilaista oli tullut hoitoon sukulaisella diagnosoidun FH:n johdosta joko suoraan tai siten, että potilaan lipidiarvoja oli ensin seurattu ja poikkeavien arvojen löydyttyä oli tehty lähete erikoissairaanhoitoon. Lisäksi havaittiin, että lääkitystä saaneilla plasman kokonaiskolesteroli oli laskenut keskimäärin 28,2 % ja LDL-kolesteroli 34,4 %. Potilaista 53,9 %:lla plasman LDL-kolesteroli oli lopputilanteessa ≤ 4,0 mmol/l, mutta vain 36,8 % oli saavuttanut kansainvälisen tavoitearvon (3,5 mmol/l).
