▼ This study is to compare primary
hyperparathyroidism (PHPT) patients with different iPTH levels for serum calcium and other laboratory values. In this retrospective study, 212 patients who presented at Robert Wood Johnson Hospital were assessed for metabolic and characteristic features of PHPT. Patients were divided into two groups according to their serum intact parathyroid hormone (iPTH) levels. Student t- tests were used to compare the two groups for differences in age, body mass index (BMI), adenoma weight, and laboratory test values which included serum calcium, iPTH, 25OHD, lipid panel, serum creatinine, ALP, and 24 hr. urinary calcium. Pearson`s correlation coefficient was used to assess the relationship. Of the 212 PHPT patients, 100 (17 males and 83 females) were classified as m-iPTH group (iPTH below 140 pg/ml), whereas 112 patients (25 males and 87 females) were classified as h-iPTH group (iPTH above 140 pg/ml). Higher-iPTH patients are younger than m-iPTH patients. No statistic significant differences in BMI, T-cholesterol and TG were found between the m-iPTH and h-iPTH groups. Higher- iPTH patients compared with m- iPTH, had slightly but significantly higher calcium, lower 25OHD, lower HDL, higher ALP, and very close to have higher adenoma weight. Additionally, we found iPTH was positive correlated with serum calcium, adenoma weight, and triglyceride (TG) levels, and negatively correlated with HDL and 25OHD. Intact PTH did not correlate with BMI and T- cholesterol levels. Furthermore, 24 hr. urinary calcium and serum ALP were positively associated with iPTH levels but not significantly (P = 0.08, P = 0.09) respectively. These correlations were independent of serum calcium and 25OHD levels except TG was dependent of reduced 25OHD, while serum ALP was dependent of calcium levels. These findings from our analysis consistent with previous studies suggesting iPTH levels correlated metabolic syndrome. Additionally, our results suggest that h- iPTH patients tend to be younger ones, with lower HDL, lower 25OHD, and higher ALP. While the underline mechanisms for these changes are unclear, we speculate that the elevated iPTH levels might decrease HDL directly or indirectly through increasing insulin resistance by weight gain, and increases ALP through PTH receptors on osteoblasts. This study supported our hypothesis that iPTH levels are an important factor to contribute in the management of PHPT patients. Intact PTH levels, lipid panel, 25OHD, ALP in addition to calcium levels might also need to be considered in the therapeutic decision for PHPT patients.

▼ textabstractIt is generally accepted that for autonomous hyperparathyroidism, whether
primary or tertiary, surgery is still the only suitable method of treatment
available. Analysis of a series of cases treated in t his way over the past
twenty years has shown that there are certain problems associated with the
treatment of this disease that have not yet been solved.
Even experienced surgeons may have difficulty in finding the parathyroid
glands when the localization or number is abnormal. The histological differentiation
between nodular hyperplastic, and adenomatous parathyroid
tissue may be extremely difficult, sometimes even impossible. It is just this
difference that might determine the amount of resection and the postoperative
course. Furthermore, in some cases it is exceedingly difficult for
the surgeon to judge whether a parathyroid is of normal size and has a
normal appearance. Lastly, the etiology of primary hyperparathyroidism
is still unknown.
In the present work the findings in 267 patients treated surgically between
1950 and 1970 are discussed and evaluated in relation to the data in
the literature. Special attention is paid to the etiology of the disease, the
histological picture, and the surgical technique. The symptomatology,
diagnosis, and biochemical changes will only be mentioned briefly, since
the problems associated with them are so numerous that they deserve
separate treatment. A thesis on these subjects is in preparation in Leiden.
Because the prognosis of associated disease, especially the renal, is the
more favourable the earlier the diagnosis is made, some principles are given
to promote earlier consideration of the diagnosis hyperparathyroidism in
cases with few symptoms.
The data of 267 patients who underwent an operation between 1950 and
1970 under the probability diagnosis hyperparathyroidism are discussed.
These patients were treated in the Leiden University Hospital, the Leiden
Diaconess Hospital, or the Rotterdam University Hospital. In 255 of t hese
cases the diagnosis was confirmed at surgery and histologically.

MEDICINE - ENDOCRINOLOGY
Uvod i cilj: Prethodno je uočeno postojanje
insulinske rezistencije i povećana prevalenca oštećene tolerancije
na glikozu i tipa 2 dijabetesa kod pacijenata sa primarnim
hiperparatireoidizmom. Efekat paratireoidektomije na insulinsku
senzitivnost je praćen kontraverznim nalazima u zavisnosti od
metode koja je korištena za procenu insulinske senzitivnosti: nije
bilo promene kada su korišteni HOMA i QUICKI dok je Minimalnim
modelom pokazano značajno poboljšanje insulinske senzitivnosti.Cilj
ovog rada je bio da se proceni insulinska senzitivnost pre i nakon
paratireoidektomije kod pacijenata sa PHPT putem euglikemijskog
hiperinsulinemijskog klampa. Materijal i metode: Kod 44 pacijenta
sa PHPT i 11 zdravih kontrola komparabilne starosti i indeksa
telesne mase procenjivali smo insulinsku senzitivnost (pomoću
tehnike klampa, HOMA IR i ISI indeksa), insulinsku sekreciju (putem
površine pod krivom za glikemije i insulinemije tokom OGTTa i
izračunavajući akutni insulinski odgovor iz podataka dobijenih
IVGTTom), lipidni profil i nivo hsCRP kao marker hronične
inflamacije. Rezultati: Pre operacije vrednosti M indeksa i HOMA IR
su ukazivale na postojanje insulinske rezistencije kod pacijenata
sa PHPT. Nije bilo razlike u M indeksu (3.74±1.89 vs 4.62±2.27, p
>0.05), HOMA IR (2.94±1.39 vs. 3.29±0.81, p > 0.05), AUC
glikoze (863.0±261.3 vs 842.3±165.5, p>0.05), AUC insulina
(7068.7±4159.0 vs 7229.6±2581.7, p>0.05), ISI (4.73±2.77 vs
4.25±2.94, p>0.05) i AIR (47.89±32.05 vs. 38.96±21.20,
p>0.05) izmeĎu pacijenata sa PHPT i zdravih kontrola. Došlo je
do značajnog poboljšanja insulinske senzitivnosti nakon operacije
al ii preoperativna i postoperativna vrednost M indeksa se nisu
razlikovale od zdravih kontrola. Nije uočena promena u HOMA IR, AUC
za glikozu i insulin ISI i AIR, lipidima i hsCRP nakon operacije.
Zaključak: Dobili smo značajno poboljšanje insulinske senzitivnosti
nakon paratireoidektomije kod pacijenata sa PHPT koristeći klamp
tehniku. Postoperativno nije do došlo do značajne promene u drugim
pokazateljima insulinske senzitivnosti, paramtrima insulinske
sekrecije, lipidima i hsCRP.

▼ Abstract
Multiple endocrine neoplasia type 1 (MEN1) is an inherited syndrome characterized by parathyroid, gastroenteropancreatic and pituitary neuroendocrine tumours. In Northern Finland, two founder mutations of the MEN1 gene (1466del12, 1657insC) accounting for the majority of the MEN1 cases, have common ancestors born in the 18th and 19th centuries, respectively. Three small clusters of familial pituitary adenoma have also been detected, two of which could be linked by genealogy to a common ancestral couple born in the 18th century.
Clinical evaluation of 82 MEN1 mutation carriers showed that age was a risk factor for most of the MEN1-related manifestations. In the whole group, nonfunctional pancreatic tumour (NFPT) was more common in the frameshift/nonsense mutation carriers (odds ratio 3.26; 95% confidence interval 1.27–8.33, P = 0.014), whereas gastrinoma was more common in the in-frame/missense mutation carriers (OR 6.77, CI 1.31–35.0, P = 0.022). In the founder mutation carriers, the 1657insC mutation predicted the risk for NFPT (OR 3.56, CI 1.29–9.83, P = 0.015), while the 1466del12 mutation was associated with the risk for gastrinoma (OR 15.1, CI 1.73–131.9, P = 0.014).
The mean ages at death of the 32 obligatory MEN1 founder mutation carriers born between 1728 and 1929 were compared to those of the 29 spouses and sex-matched life expectancy estimates derived from Finnish national statistics. The ages at death of the mutation carrier males (61.1 ± 12.0 years) and females (67.2 ± 10.7 years) did not differ from the control groups.
PAP (pituitary adenoma predisposition) locus was mapped in the chromosome region 11q12–11q13 by whole-genome single-nucleotide polymorphism genotyping. Combining the linkage and the gene expression array data, AIP (aryl hydrocarbon receptor interacting protein) was chosen for sequencing. The nonsense mutation Q14X was identified in the affected (acromegaly, gigantism, prolactinoma) family members and in four other patients. Loss of heterozygosity was detected in pituitary adenomas of AIP mutation carriers.
Mutation analysis of MEN1, HRPT2 (hyperparathyroidism 2), CASR (calcium-sensing receptor), CDKN1B (cyclin-dependent kinase inhibitor 1B) and AIP genes was performed in primary hyperparathyroidism patients with features of inherited predisposition. One out of 29 patients was found to have the 1466del12 mutation, while no mutations were detected in other genes.

The experience of minimally invasive
endocrine surgery accumulated at Vilnius University Centre of
Abdominal Surgery is presented in this review of scientific
publications submitted for habilitation procedure. The material
concerning minimally invasive thyroid gland operations is
summarized and the results of two clinical trials are evaluated.
The results of prospective randomized study “Evaluation of two
methods endoscopic adrenalectomy” were presented and analyzed; this
study included 70 patients who underwent surgery for various
pathology of adrenal glands; one group of the patients underwent
laparoscopic minimally invasive operation and another one –
endoscopic retroperitoneal minimally invasive surgery. The
relationship between the size of adrenal gland tumour, patients’
body weight and duration of operation was analyzed; blood loss and
rate of operative complications were compared. The evaluation of
all data showed that both methods of surgery were acceptable;
however, laparoscopic adrenalectomy was more was easier to learn.
Clinical study “Minimally invasive focused and traditional
parathyroidectomy for treatment of primary hyperparathyroidism: a
prospective randomized study” was performed during the period since
2005 till 2007; the results of treatment of patients by means of
two methods of surgery were presented. The patients (n = 47) were

▼ [EN] Purpose of the dissertation thesis is to analyse the diagnostic, clinical and therapeutic aspects of BMD-CKD in the course of conservative and haemodialysis treatment by examining the diagnostic and prognostic value of contemporary biomarkers for the development of secondary hyperparathyroidism and BMD-CKD; imaging studies of variations of the parathyroid gland and bone-dental changes; comparison of the clinical efficacy of calcimimetics and paricalcitol in the development of sHPT and BMD; analysis of the dynamic influence of phosphor-binding binders on markers of BMD-CKD; traceability and safety; appreciation of combination treatment with vit.K2 and calcitriol; examining individual quality of life and developing an algorithm for BMD-CKD. The study was conducted between 1.1.2015 and 31.12.2017 with 338 patients with CKD and on HD in St.Marina University Hospital - Varna. The work proves the diagnostic and prognostic value of the complex analysis of the indicators BMD-CKD as a result of medication and HD treatment; elevated levels of FGF-23 at an early stage represent a prognostic marker for risk of cardiovascular diseases; increased levels of OC and BAP in HD with high level of PTH testify to HTBD-sHPT. Image studies for evaluation of parathyroid glands in sHPT have a significant role. Calcimimetic and paricalcitol suppress the secretion of PTH and shorten period of hyper Ca. Renagel is shown to control hyper P and a decrease FGF-23. Vit.K2 may be combined with medications used to treat BMD and protect against calcifications. Dental changes change BMD and should be treated. The questionnaire and algorithm we have modified is a reliable basis for a complex and individualized approach. /////////////// /////////////// [BG] Цел на дисертационната разработка е анализ на диагностичните, клинични и терапевтични аспекти на КМН-ХБЗ в хода на консервативното и хемодиализно лечение чрез изследване на диагностичната и прогностична стойност на съвременни биомаркери за развитие на вторичен хиперпаратиреоидизъм и КМН-ХБЗ; образни изследвания на измененията на ПЩЖ и костно-дентални промени; съпоставка на клиничната ефективност на калцимиметици и парикалцитол при развитието на ВтХПТ и КМН-ХБЗ; анализ на динамичното влияние на фосфор-свързващите байндери върху маркери на КМН-ХБЗ; проследена ефективност и безопасност; апробиране комбинираното лечение с вит.К2 и калцитриол; изследване на индивидуално качество на живот и разработване на алгоритъм за КМН-ХБЗ.

▼ Introdução: O quelante de fósforo (P) Osvaren® foi lançado recentemente no mercado internacional para tratamento da hiperfosfatemia nos pacientes com Doença Renal Crônica (DRC). Não existem estudos experimentais com esta medicação. Objetivo: Avaliar a ação deste quelante no tratamento do Distúrbio Mineral e Ósseo (DMO) de ratos com DRC induzida por adenina e por nefrectomia 5/6 (NX5/6). Métodos: Experimento 1: Durante 4 semanas, ratos Wistar receberam dieta com adenina [2 semanas (0,75%); 2 semanas (0,50%)] e então foram divididos em 3 grupos para receber dieta padrão (grupo DRC); dieta padrão com 3% de Acetato de Cálcio (grupo Ca); e dieta padrão com 3% de Osvaren® (grupo CaMg). Um grupo Controle (função renal normal) recebeu a dieta padrão durante todo o estudo. Ao final de cinco semanas de tratamento os animais foram sacrificados. Experimento 2: ratos da mesma espécie foram submetidos à NX5/6, divididos em grupos como no experimento 1 para
receberem os quelantes de P imediatamente após a nefrectomia, e sacrificados após 9 semanas. Nos dois experimentos foram coletados soro, fêmures, aortas e paratireóides para análise bioquímica, histomorfometria óssea, pesquisa de calcificação vascular (CV) e imunohistoquímica de paratireóides, respectivamente. Resultados: Experimento 1: Os animais que receberam adenina apresentaram níveis maiores de creatinina, PTH, P e magnésio (Mg) que os do grupo Controle. Os quelantes de P reduziram a fração de excreção de P (FeP), mas não o P sérico, enquanto os níveis de PTH, FGF23 e calcitriol diminuíram de forma não significativa nos grupos tratados. O Mg sérico foi significativamente maior no grupo CaMg, enquanto maior calciúria, mais CV e menor marcação pelo PCNA nas paratireóides foram observadas no grupo Ca. Os animais que receberam adenina apresentaram doença óssea mista e ambos os quelantes de P melhoraram a remodelação, mas favoreceram a um acúmulo ainda maior de osteóide. Experimento
2: Da mesma forma que no experimento 1, o animais submetidos à NX5/6 evoluíram com uremia, e os efeitos dos quelantes no PTH, na CV e nas paratireóides foram similares. No entanto, o grupo CaMg apresentou mortalidade de 54% (vs 20% no grupo Ca), além de retardo na mineralização óssea. Conclusão: O tipo de nefropatia pode ter influência no efeito do quelante de P Osvaren®, já que o acúmulo de Mg provavelmente foi o responsável pela maior mortalidade e déficit de mineralização observados no experimento 2. Em relação ao efeito como quelante de P, o Osvaren® foi equivalente ao acetato de cálcio, mas este último está associado a maior sobrecarga de cálcio e a CV. O acúmulo de osteóide observado em ambos os experimentos parece ser o preço pago pela reduzida absorção intestinal de P favorecida pelos quelantes no hiperpatireoidismo secundário severo e esse efeito deveria ser avaliado em pacientes em diálise
Introduction: Osvaren® is a phosphate (P) binder that has been recently
introduced for Chronic Kidney Disease (CKD) patients therapy. However, it has not been tested in experimental models yet.…

▼ INTRODUÇÃO: A monitorização do paratormônio rápido (PTHr) é padrão no tratamento cirúrgico do hiperparatireoidismo primário, para garantir a retirada da paratireoide doente e preservação das saudáveis. Sua utilidade no tratamento cirúrgico do hiperparatireoidismo secundário à doença renal crônica é controversa. Esse estudo tem como objetivo verificar: 1) se a medida PTHr auxilia na predição do resultado cirúrgico precoce; 2) se existem diferenças de comportamento do PTHr entre pacientes dialíticos e transplantados; 3) se existem diferenças de comportamento do PTHr entre modalidades de operações distintas; 4) a acurácia do método em predizer controle do hiperparatireoidismo renal. MÉTODOS: Trata-se de estudo de coorte retrospectiva e prospectiva observacional, de pacientes com diagnóstico de HPTr, dialítico ou persistência após transplante renal, submetidos a paratireoidectomia total ou subtotal em único centro, no período de 2011 a 2016. Durante a
cirurgia, realizamos coletas seriadas do PTHr, sendo três dessas amostras antes da exérese das glândulas paratireoides (basal periférico, basal central e pré-retirada), e duas após ressecção (10 min e 15 min). O critério de queda porcentual igual ou maior a 80% do maior valor entre as amostras basais, em 10 minutos, foi arbitrado preditor de êxito intra-operatório. Os pacientes foram seguidos durante intervalos regulares (15 dias, 3, 6 e 12 meses). Foram divididos em dois grupos (sucesso e falha da operação) de acordo com o controle dos níveis de PTH, cálcio e fósforo conforme consensos internacionais, ao término do seguimento de 1 ano. RESULTADOS: Duzentos e vinte e oito pacientes foram elegíveis, sendo 186 (81,6%) dialíticos e 42 (18,4%) transplantados. A paratireoidectomia alcançou sucesso em 92,1% (210/228) e falha em 7,9% (18/228) dos pacientes, sem diferenças de resultados entre grupos de diagnósticos diferentes e/ou tipos de operações distintas. O principal motivo de falha foi
presença de glândula supranumerária, em 61,1% dos casos (11/18). A amostra basal central (BC) representou o real maior valor basal do PTHr para ambos os diagnósticos, porém com maior chance de picos do PTHr na amostra pré-retirada (PRE) nos pacientes transplantados. Após remoção da massa de tecido paratireóideo doente, os níveis de PTHr foram menores em 10 minutos quando comparados com as amostras basais (resultado estatisticamente significativo) para todos diagnósticos, tipos de operações e desfechos terapêuticos. No grupo sucesso, houve diferença estatisticamente significativa, entre as medidas de 10 e 15 minutos entre si, com valores menores em 15 minutos, enquanto que no grupo falha, sem distinção de 10 e 15 minutos entre si e com valores médios maiores em 15 min. Os valores do PTHr foram maiores no paciente dialítico quando comparados com transplantado, em todas as amostras (p < 0,001). No grupo sucesso, os pacientes dialíticos e transplantados, e os pacientes dialíticos
submetidos a exérese total e subtotal apresentaram porcentual de queda do PTHr semelhantes em 10 e 15 minutos para as…

▼ Dissertação de Mestrado Integrado em Medicina Veterinária
Canine primary hyperparathyroidism (PHPTH) is an endocrine disorder, where one or more
parathyroid glands autonomously produce and secrete parathyroid hormone (PTH), which
results in hypercalcaemia (Feldman, 2010).
Diagnosis of PHPTH is achieved when there are inappropriate PTH concentrations (normal
or increased) in the presence of elevated ionised calcium (iCa) concentration with no other
identifiable cause (Skelly, 2012). iCa is the only active fraction of calcium and does not
always correlate to total calcium, which is why iCa should be used to assess serum calcium
status (Schenck & Chew, 2008).
PHPTH is usually diagnosed after detection of hypercalcaemia in a blood analysis performed
for unrelated reasons, as clinical signs are often not perceived by the owners (Feldman, Hoar,
Pollard, & Nelson, 2005; Feldman, 2015a).
Treatment by parathyroidectomy, percutaneous ultrasound-guided ethanol ablation or
percutaneous ultrasound-guided heat ablation is curative and prognosis is excellent for
treated dogs, but hypocalcaemia is a frequent postoperative complication (Caplan, 2013;
Feldman, 2015a; Flanders, 2003; Nelson, 2009; Rasor, Pollard, & Feldman, 2007; Séguin &
Brownlee, 2012).
The retrospective study had the objective of characterising a sample of six dogs diagnosed
with PHPTH at Anderson Moores Veterinary Specialists and analyse the procedures and
tests conducted in the clinical approach to previously identified hypercalcaemia.
RESUMO - Hiperparatiroidismo primário canino: abordagem clínica à hipercalcémia - O hiperparatiroidismo primário canino (PHPTH) é uma doença endócrina, na qual uma ou
mais glândulas paratiróides produzem e secretam hormona paratiroideia ou paratormona
(PTH) autonomamente, o que resulta em hipercalcémia (Feldman, 2010).
O diagnóstico de PHPTH é efectuado quando existem concentrações de PTH inapropriadas
(normais ou aumentadas) na presença de concentrações aumentadas de cálcio ionizado
(iCa) sem outra causa identificável (Skelly, 2012). O iCa é a única fracção activa do cálcio e
nem sempre se correlaciona com o cálcio total, motivo pelo qual o iCa deve ser utilizado
para avaliar o cálcio em circulação (Schenck & Chew, 2008)
O PHPTH é normalmente diagnosticado após a detecção de hipercalcémia numa análise
sanguínea efectuada por motivos não relacionados, uma vez que os sinais clínicos
normalmente não são identificados pelos donos (Feldman, Hoar, Pollard, & Nelson, 2005;
Feldman, 2015a)..
O tratamento com paratiroidectomia, ablação percutânea com etanol guiada por ultra-som
ou ablação percutânea com calor guiada por ultra-som é curativo e tem um prognóstico
excelente para animais tratados, embora a hipocalcémia seja uma complicação póscirurgica
frequente (Caplan, 2013; Feldman, 2015a; Flanders, 2003; Nelson, 2009; Rasor,
Pollard, & Feldman, 2007; Séguin & Brownlee, 2012).
O estudo retrospectivo deste trabalho teve como objectivo a caracterização de uma amostra

▼ Background Ultrasound (US) and technetium-99m sestamibi scintigraphy (MIBI) are used to determine the localization of abnormal glands in cases of primary hyperparathyroidism (PHPT). Intraoperative intact parathyroid hormone (iPTH) monitoring is a reliable examination used to cure PHPT. The aim was to assess the necessity of intraoperative iPTH monitoring. Methods Sixty patients were examined using preoperative MIBI and US. iPTH was measured at 3 time points: (1) at the start of surgery; (2) 10 minutes after gland resection; and (3) more than 60 minutes after surgery. We defined a decreased iPTH level as an iPTH measured 10 minutes after resection that was less than 50% of the preoperative level. Results The iPTH of 55 patients with concordant lesions decreased to within the normal range more than 60 minutes after surgery. Conclusions It is not necessary to monitor intraoperative iPTH when single concordant lesions are preoperatively identified on both MIBI and US.

▼ Background: Lithium is the most effective long-term treatment for bipolar disease. It has, however,been associated with hypercalcemia and hyperparathyroidism. The aim of the study is to research howlithium associated hyperparathyroidism(LHPT)affects bone mineral density. Method: A sub-analysis was performed on an ongoing randomized prospective study evaluating the operation results from parathyroidectomy versus watchful waiting in 22patients with LHPT. The patients were followed-up for 2 years and their blood samples, bone mineral density (BMD) and FRAX assessment were analysed. The data from LHPT patients was also compared to a separate group of patients with primary hyperparathyroidism (PHPT) corresponding in age.Results: In comparing LHPT patients with PHPT apparent differences in the biochemical profile were detected, including elevated values of ionized Ca in PHPT (p=0.001), lower excretion of 24h urinary calcium in LHPT (p=0.003) and significantly higher values of PTH excretion in PHPT. LHPT showed tendencies to having better BMD (p=0.176). At 2-year follow-up of 8 LHPT patients, biochemicalvalues improved, suggesting cure, including lower risks of skeletal fractures. Discussion: The biochemical features in LHPT are distinctive from PHPT. However, each case is unique, and thebiochemicalvariety issimilar to PHPT. Confounding factors include age, sex, renal function and stability of the bipolar condition. Conclusions:The present study illustratesthat LHPT differs biochemically from PHPT. In comparison to PHPT, LHPT patients tend to have reduced BMD and the present study could not confirm the previous postulation that lithium could be protective of the skeleton. In conclusion, casesof LHPT should be assessed individually, since the clinical course is diverse. In patients risking fracture, parathyroidectomy should be considered.

▼ Chronic Kidney Disease (CKD), osteoporosis and mild hyponatremia are all prevalent chronic conditions that may coexist and are often under-recognized. Mineral-Bone Disorder begins early in the natural history of CKD and results in complex abnormalities of bone which ultimately confers a well-established increased risk of fragility fractures in End Stage Kidney Disease. Hyponatremia is a novel, usually renal mediated metabolic perturbation, that most commonly occurs independently of the stage of renal dysfunction but which may also predispose to increased fracture risk. The extent -if any- to which either early stages of renal dysfunction or the presence of hyponatremia contribute to fracture occurrence in the general population, independently of osteoporosis, is unclear. Renal transplantation is the treatment of choice for ESKD and although it restores endogenous renal function it typically fails to normalize either the long term cardiovascular or fracture risk. One potential mechanism contributing to these elevated long-term risks and to diminished Health Related Quality of Life is persistent, post-transplant
hyperparathyroidism. In this study we retrospectively examine the association of renal function and serum sodium with Bone Mineral Density and fracture occurrence in a retrospective cohort of 1930 female members of the general population who underwent routine DXA scan. We then prospectively recruited a cohort of 90 renal transplant recipients in order to examine the association of post transplant parathyroid hormone (PTH) level with measures of CKD Mineral Bone Disorder, including, DXA Bone Mineral Density, Vascular Calcification (assessed using both abdominal radiography and CT techniques, as well as indirectly by carotid-femoral Pulse Wave Velocity) and Quality of Life (using the Short Form-12 and a PTH specific symptom score). In the retrospective DXA cohort, moderate CKD (eGFR 30-59ml/min/1.73m2) and hyponatremia (<135mmol/L) were associated with fracture occurrence, independently of BMD, with an adjusted Odds Ratio (95% Confidence Interval), of 1.37 (1.0, 1.89) and 2.25 (1.24, 4.09) respectively. In the renal transplant study, PTH was independently associated with the presence of osteoporosis, adjusted Odds Ratio (95% Confidence Interval), 1.15 (per 10ng/ml increment), (1.04, 1.26). The presence of osteoporosis but not PTH was independently associated with measures of vascular calcification, adjusted ß (95% Confidence Interval), 12.45, (1.16, 23.75). Of the eight quality-of-life domains examined, post-transplant PTH (per 10ng/ml increment), was only significantly and independently associated with reduced Physical Functioning, (95% Confidence Interval), 1.12 (1.01, 1.23). CKD and hyponatremia are both common health problems that may contribute to fracture occurrence in the general population, a major on-going public health concern. PTH and decreased Bone Mineral Density may signal sub-optimal long-term outcomes post renal transplantation, influencing bone and vascular health and to a limited extent long…

▼ In the general population, fractures are a significant healthcare issue. However, fractures also complicate several endocrine disorders. The overall aim of my study was to investigate the changes in bone structure and material composition underlying bone fragility in a number of endocrine diseases such as type 1 and type 2 diabetes mellitus as well as patients with PTH excess and PTH deficiency.
High-resolution peripheral quantitative computed tomography was used to acquire images of the distal radius and tibia in cases and controls. Bone structure was assessed by the standard analysis protocol from the manufacturers that uses a threshold base algorithm in the type 1 and type 2 diabetes studies. A non-threshold base algorithm was used to analyze bone structure and matrix mineral density in the PTH excess and PTH deficiency study.
The main findings were that patients with type 1 diabetes had no significant deficits in cortical and trabecular bone relative to controls. Patients with T1DM had a tendency towards lower bone formation and bone resorption markers. Patients with type 2 diabetes had similar cortical morphology whereas trabecular bone was better maintained than controls. These results are consistent with higher BMD in the spine and hip as well as lower bone remodelling markers observed in diabetic patients.
PTH excess is deleterious to both cortical and trabecular bone. In patients with untreated primary hyperparathyroidism (PHPT), the normal or high trabecular density reported in several studies is likely to be the result of inclusion of cortical remnants in the medullary compartment. In patients with untreated PHPT, there was a left shift of the void-matrix mineralization density distribution curve relative to controls due to increased cortical porosity. Cortical and trabecular deficits in untreated PHPT may not be completely reversible with surgical treatment. Patients with PTH deficiency due to secondary rather than primary hypoparathyroidism have better maintained cortical and trabecular bone relative to controls as well as higher matrix mineral density. Similar results were found in women and in men. There was a rightward shift of the void bone matrix mineralization distribution curve for patients with hypoparathyroidism relative to controls.
In conclusion, patients with type 1 and type 2 diabetes may have underlying bone fragility predisposing to fractures, but my study failed to identify microstructural abnormalities. Further work is needed to determine whether abnormalities in the material properties of bone may account for the increased fracture risk seen in diabetes. Patients with PTH excess have deficits to both cortical and trabecular bone. The normal or high trabecular density reported in several studies is likely to be the result of inclusion of cortical remnants in the medullary compartment. Patients with PTH deficiency due to secondary hypoparathyroidism rather than primary hypoparathyroidism have better maintained cortical and trabecular bone morphology as well as higher matrix…

▼ Cette thèse de mathématiques appliquées en physiologie rénale a pour thème principal l'étude de l'homéostasie du calcium à travers le développement d'un modèle mathématique à l'échelle de l'organisme. Nous cherchons à répondre à certaines questions soulevées par les néphrologues dans le cas de pathologies impliquant la formation de calculs rénaux ou de calcifications. Nous examinons notamment les cas de l'hypercalciurie observée durant l'hyperparathyroïdie primaire dont les causes ne sont pas élucidées ainsi que les mécanismes de complexation du calcium et phosphate et notamment les conséquences d'une infusion intraveineuse de phosphate sur l'homéostasie du calcium. Notre modèle est composé d'équations différentielles décrivant la dynamique du calcium dans les compartiments impliqué dans son métabolisme (intestin, os, reins) ainsi que les mécanismes de régulation par l'hormone parathyroïdienne (PTH), la vitamine D3 et le récepteur sensible au calcium (CaSR). Ce modèle est par ailleurs couplé à un modèle de l'homéostasie du phosphate. Les résultats de ce modèle suggèrent que la présence ou non d'une hypercalciurie lors de l'hyperparathyroïdie primaire peut être expliquée par des mécanismes antagonistes dans la branche ascendante large de Henle, avec d'un côté le CaSR inhibant la réabsorption de calcium et de l'autre la PTH diminuant l'excrétion de calcium. Nous concluons que l'infusion intraveineuse de phosphate induit une hypocalcémie majeure, due principalement à la précipitation du calcium et du phosphate dans le plasma et dans l'os. En outre, cette étude suggère un retard dans l'activation de la synthèse de PTH par le phosphate.
This thesis of applied mathematics in renal physiology focuses on the study of calcium homeostasis, through the development of a mathematical model at the organism scale. This model is built based upon recent experimental studies as well as previous models in the field. We aim to answer several questions raised by nephrologists regarding diseases involving calcium stone formation or calcifications. In particular, we are interested in the origins of the hypercalciuria observed during primary hyperparathyroidism, the causes of which remain to be elucidated, the effects of bone resorption inhibition by bisphosphonates on calcium metabolism, as well as the consequences of an intravenous infusion of phosphate on calcium homeostasis. Our model is composed of differential equations describing the dynamics of calcium in the compartments involved in its metabolism (intestine, bone and kidneys), as well as complex feedback mechanisms by parathyroid hormone (PTH), vitamin D3 and the calcium sensing receptor (CaSR). Besides, this model is coupled to a phosphate homeostasis model. This model suggests that the variable presence of hypercalciuria during primary hyperparathyroidism can be explained by counteracting mechanisms in the thick ascending limb of Henle, involving on one hand the calcium sensing receptor, which inhibits calcium reabsorption, and on the other hand PTH which decreases calcium…

▼ A hiperfosfatemia está relacionada com o hiperparatireoidismo secundário renal (HPTSR) e com a progressão da doença renal crônica (DRC). A retenção de fósforo estimula a síntese do fator de crescimento de fibroblastos 23 (FGF-23), o qual promove fosfatúria, com o objetivo de evitar o aparecimento de hiperfosfatemia. Atualmente, o tratamento disponível para DRC é de manutenção e, portanto, novas estratégias para evitar a progressão da DRC seriam de grande relevância. Recentemente têm sido demonstrado o papel da célula-tronco mesenquimal (CTM) em minimizar os mecanismos inflamatórios e imunológicos envolvidos na progressão da DRC. Portanto, o estudo teve como hipótese de que a CTM possa evitar ou controlar a progressão para o HPTSR, investigada por meio da avaliação de biomarcadores do metabolismo de fósforo, ou seja, as concentrações sérica de fósforo (sP), FGF-23, cálcio total e cálcio ionizado, bem como a excreção fracionada de fósforo urinária
(uFEP) em cães com DRC nos estágios 2 (Grupo A) e 3 (Grupo B), submetidos ou não a terapia com CTM, bem como investigar se os valores elevados de FGF-23 estariam relacionados com o menor tempo de sobrevida. Trata-se de um estudo prospectivo, longitudinal, duplo-cego e randomizado em que foram avaliados 22 cães com DRC, tratados com solução fisiológica (SF) ou CTM, avaliados a cada 30 a 45 dias em 12 momentos (T0 a T12). No Grupo A (n= 9; SF: n= 6, CTM: n= 3) todos os cães eram normofosfatêmicos no momento inicial do acompanhamento (T0) e foi observado níveis elevados de FGF-23 em 33,3% dos cães (3 de 9), assim como o aumento de uFEP foi detectado em 33,3% dos casos (3 de 9). A média ± EPM dos valores de FGF-23 sérico do Grupo A foi de 481,5 ± 75,23pg/mL. Já no Grupo B (n = 13; SF: n = 6, CTM: n = 7), todos os cães apresentaram altas concentrações séricas de FGF-23 desde T0 (média ± EPM de 12744 ± 6879pg/mL), sendo que 53,8% dos cães eram normofosfatêmicos. A média ± EPM de fósforo
sérico em T0, T6 e T12 ou momento do óbito no Grupo A e B foi de 3,74 ± 0,13mg/dL e 6,40 ± 0,54mg/dL. Ao longo do curso da doença, o desenvolvimento de hiperfosfatemia foi observada em apenas 11,1% dos cães do Grupo A e em 84,6% dos cães do Grupo B. O Grupo B (SF e CTM) apresentou valores mais elevados de FGF-23 do que o Grupo A (SF e CTM), e foi detectada diferença estatística entre os dois grupos. A uFEP nos cães dos Grupos A e B em T0, T6 e T12 ou óbito obteve média ± EPM de 20,93 ± 3,92% e 24,05 ± 2,22%, respectivamente. Além disso, a sobrevida foi menor no Grupo B, a qual estava associada com hiperfosfatemia intensa, altas concentrações de FGF-23 e diminuição da uFEP. Dessa forma, em cães DRC normofosfatêmicos, a presença de aumentos de uFEP e de FGF-23 parece terem atuado como marcador precoce do HPTSR. Em contrapartida, nos estágios tardios da DRC, o aumento de FGF-23 associado a diminuição da uFEP pode indicar mau prognóstico. Em relação à terapia com CTM nos cães com DRC, de
acordo com o número de cães avaliados e os resultados obtidos, não foi possível concluir de forma contundente sobre…

▼ Introduction:
Since the introduction in the 1970s of the unilateral approach in surgery for primary hyperparathyroidism by Wang, authors have increasingly been recommending limited forms of parathyroid surgery. Although unilateral explorations reduce operation time and admission days, decrease operative risk and give better cosmetic results, the debate about the best surgical treatment for primary hyperparathyroidism has never been settled. Bilateralists oppose less invasive approaches because they estimate the incidence of multiple gland disease to be as high as 30%. However, in spite of a systematic bilateral exploration of the neck in search of the diseased parathyroid gland, with identification and estimation of the size of all parathyroid tissue, in only 44% of cases are four glands identified, in 37% three, and in 19% less than three.
In chapter 1 we reported an exceptional case of persistent hyperparathyroidism (due to a non-descended inferior parathyroid) after extensive bilateral exploration, illustrating a clinical dilemma that can be encountered in parathyroid surgery. Imaging carried out prior to re-exploration and including, among other methods, ultrasonography and computed tomography, revealed a parathyroid adenoma at the level of the mandibular angle and the hyoid bone. Guided by the imaging results the adenoma was successfully resected by a local direct procedure taking less than 10 minutes.
In general, the main reason an adenoma is not found during exploration is the variability in location, rather than variety in the number of glands. It is therefore of pivotal importance to understand not only the anatomy, but also the embryology of the parathyroid glands. As radiologist John Doppman succinctly stated, If you are an experienced parathyroid surgeon and not able to find a tumor, you cannot have looked high enough.
Since primary hyperparathyroidism can be diagnosed with nearly 100% accuracy and successfully treated in more than 95% of cases, surgery is the treatment of choice. The gold standard in parathyroid surgery has been conventional neck exploration (CNE), and with success rates exceeding 95% and virtually no complications nothing more seemed left to be desired. However, it cannot be denied that there is a discrepancy between the extent of the operation and the size of the offending gland in the majority of patients. Encouraged by the pace of development in methods of imaging (resulting in increased accuracy), combined with the knowledge that primary hyperparathyroidism is caused by a solitary adenoma in at least 85% of cases, and our experience of the relatively simple and quick MIA procedure (chapter 1) we wondered whether such a direct, minimally invasive strategy could be utilized for the more common cases of primary hyperparathyroidism as well.
For this purpose we formulated the following hypothesis (chapter 3): A substantial group of patients with primary hyperparathyroidism can be successfully treated by limited access surgery after preoperative localization studies and may thus be…

While it is still important to have a high volume parathyroid surgeon, the trend away from bilateral neck exploration towards that of minimal invasive parathyroidectomy (MIP) has changed the perioperative management of parathyroid disease.

▼ The primary
hyperparathyroidism (PHPT) is the third most common endocrinological diagnosis and it is characterized by excessive, inadequate and poorly regulated parathyroid hormone (PTH) secretion. The bone is one of the target organs of PHPT and the presence of osteoporosis at any localitation, is indication for surgical treatment. However, the response of the bone to this treatment is not uniform and generalized in all patients.
The hypothesis of this study is that the evolution of bone mass after parathyroidectomy (PTx) is related and/or conditioned by various demographic, clinical, laboratory and genetic factors.
MATERIAL AND METHODS: We performed a prospective observational study between january 1999 and december 2012. The study included 159 postmenopausal women with PHPT who underwent PTx. Analytical and densitometric measurements were perfomed before PTx and at one and two years of follow-up. Also, different genetics polymorphisms related to bone-mineral metabolism and the physiopathology of PHTP were genotyped.
RESULTS: The prevalence of osteoporosis is higher in women with PHPT than in the general population and the most affected bone is the cortical bone (90% of patients with PHPT has osteopenia or osteoporosis at ultradistal radius area). Bone mineral density (BMD) increases significantly after PTx in all locations (p<0,001) except in the proximal third of the distal radius (p=0,374).
Younger women (P=0,016) and women with a later menopause (p=0,026) have a greater increase in BMD in the total hip (TH) after PTx, and a high BMI (p=0,008) is related with greater recovery of BMD at femoral neck (FN).
A high basal PTH (p<0,01) and a greater decrease after PTx (p<0,05), are associated with a greater increase in BMD after PTx at all sites studied. A elevated basal 1,25-OH2 Vitamin D is associated with a greater increase in BMD at TH (p=0,014). A low baseline BMD is associated with a greater increase in bone mass after PTx at FN and TH level (p=0,004 and p=0,03 respectively).
Genotype A/C for the rs7975232 polymorphism of the VDR gene (p=0,022) and genotype A/A for rs1042636 polymorphism of the CaSR gene (p=0,048) are most frecuently in patients with PHPT. The C allele for rs9594738 polymorphism to RANKL gene and the G allele for rs1032128 polymorphism to OPG gene have been linked to a higher baseline BMD at the lumbar spine (p=0,029 and p=0,02 respectively). The presence of the G allele of rs4646536 polymorphism of the CYP27B1 gene is associated with a greater BMD recovery after PTx at TH(p=0,006). These differences are not statistically significant if the results are corrected by the Bonferroni method.
CONCLUSIONS: The most affected bone in PHPT is cortical bone; however, the higher BMD recovery after PTx is produced at the trabecular bone. Patients with more severe PHPT (higher basal PTH, greater PTH decrease after PTx, increased basal 1,25-OH2 Vitamin D and lower baseline BMD) are those with greater BMD recovery after surgery. Younger women, those with a later menopause and those with a higher BMI…

▼ Introduction:
Since the introduction in the 1970s of the unilateral approach in surgery for primary hyperparathyroidism by Wang, authors have increasingly been recommending limited forms of parathyroid surgery. Although unilateral explorations reduce operation time and admission days, decrease operative risk and give better cosmetic results, the debate about the best surgical treatment for primary hyperparathyroidism has never been settled. Bilateralists oppose less invasive approaches because they estimate the incidence of multiple gland disease to be as high as 30%. However, in spite of a systematic bilateral exploration of the neck in search of the diseased parathyroid gland, with identification and estimation of the size of all parathyroid tissue, in only 44% of cases are four glands identified, in 37% three, and in 19% less than three.
In chapter 1 we reported an exceptional case of persistent hyperparathyroidism (due to a non-descended inferior parathyroid) after extensive bilateral exploration, illustrating a clinical dilemma that can be encountered in parathyroid surgery. Imaging carried out prior to re-exploration and including, among other methods, ultrasonography and computed tomography, revealed a parathyroid adenoma at the level of the mandibular angle and the hyoid bone. Guided by the imaging results the adenoma was successfully resected by a local direct procedure taking less than 10 minutes.
In general, the main reason an adenoma is not found during exploration is the variability in location, rather than variety in the number of glands. It is therefore of pivotal importance to understand not only the anatomy, but also the embryology of the parathyroid glands. As radiologist John Doppman succinctly stated, If you are an experienced parathyroid surgeon and not able to find a tumor, you cannot have looked high enough.
Since primary hyperparathyroidism can be diagnosed with nearly 100% accuracy and successfully treated in more than 95% of cases, surgery is the treatment of choice. The gold standard in parathyroid surgery has been conventional neck exploration (CNE), and with success rates exceeding 95% and virtually no complications nothing more seemed left to be desired. However, it cannot be denied that there is a discrepancy between the extent of the operation and the size of the offending gland in the majority of patients. Encouraged by the pace of development in methods of imaging (resulting in increased accuracy), combined with the knowledge that primary hyperparathyroidism is caused by a solitary adenoma in at least 85% of cases, and our experience of the relatively simple and quick MIA procedure (chapter 1) we wondered whether such a direct, minimally invasive strategy could be utilized for the more common cases of primary hyperparathyroidism as well.
For this purpose we formulated the following hypothesis (chapter 3): A substantial group of patients with primary hyperparathyroidism can be successfully treated by limited access surgery after preoperative localization studies and may thus be…

▼ Introduction: Recent evidence suggests that primary hyperparathyroidism (pHPT) is linked with hypertension and atherosclerosis, even though the results of studies are often conflicting. PHPT is found in a high proportion (2-3%) in postmenopausal women. Co-existence of non-traditional risk factors with an already adverse traditional cardiovascular (CV) risk factor profile in menopause, may substantially and unpredictably alter the net CV risk profile in this population. Methods: One hundred and two postmenopausal women with pHPT without clinically overt cardiovascular disease were consecutively recruited and were matched 1:1 for age and duration of menopause with 102 postmenopausal women with normal PTH, Ca and P levels and without clinically overt CV disease. A complete biochemical assessment was done in all patients and we used non-invasive cardiovascular techniques for identifying subclinical damage of the arterial wall (brachial artery flow - mediated dilation (FMD), pulse wave velocity (PWV), pulse wave analysis to determine the arterial pressure augmentation index (ΑΙ%) and aortic blood pressure, carotid and femoral intima - media thickness measurements (ΙΜΤ) and determination of atherosclerotic plaques by ultrasound method.Results: Postmenopausal women with pHPT had higher PTH and calcium levels, and lower levels of phosphorus and 25 hydroxyvitamin D as expected. They had also higher BMI, HBA1c, HOMA-ir, CRP and triglycerides, higher prevalence of untreated hypertension and lower prevalence of hyperlipidemia (p<0.05 for all). Concerning their hemodynamic and vascular profile, pHPT patients had higher peripheral systolic (p=0.03) and diastolic (p<0.001) and aortic systolic (p=0.002) and diastolic (p<0.001) blood pressure and marginally higher PWV (p=0.084) compared to postmenopausal women without pHPT. After adjustment for risk factors differing between the 2 groups the presence of pHPT was an independent determinant of peripheral and aortic systolic and diastolic BP only (p<0.05 for all). Further adjustment for CRP revealed that only peripheral (p=0.025) and aortic (p=0.004) diastolic BP remained significantly higher in the pHPT group. Finally, after adjustment for vitamin D3 levels the results were not altered while after adjustment for PTH levels there were no statistically significant differences in these markers between the two groups.Conclusion: These results suggest that pHPT is associated with increased peripheral and aortic blood pressure. In this correlation, PTH levels and inflammatory load seem to play a pivotal role. In contrast, a direct impact of the disease on subclinical atherosclerosis cannot be implicated despite the large number of relevant markers of measured in this study. Given the steep increase in CV risk after menopausal transition, pHPT may further aggravate incident hypertension and CV danger in postmenopausal women. Therefore, early diagnosis and careful control of blood pressure is important for these women especially when they do not fulfill the criteria for…

▼ The objective of the study was to evaluate the effect of parathyroidectomy (PTX) vs.35 mg ow risedronate administration on volumetric bone mineral density (vBMD) andbone geometry at the tibia in postmenopausal women with primaryhyperparathyroidism (PHPT). Our open label prospective observational studyincluded 32 postmenopausal women with PHPT as the study group. 16 underwentPTX and 16 were treated with 35 mg ow risedronate for 2 years. We assessed aBMDby DXA, vBMD, bone mineral content (BMC), cortical and trabecular area, byperipheral quantitative computed tomography (pQCT) at the tibia at baseline and attwo years. Risedronate did not result in any significant change on vBMD andstructural pQCT indices. PTX resulted in significant increase in trabBMC (6.44%)and vBMD (4.64%), with % increase being significantly higher over risedronate(p<0.05). At cortical sites there was no significant change following PTX. However,the % change in cortvBMD was higher following PTX vs. risedronate (0.39% vs. -0.26%, p<0.05). In conclusion in postmenopausal women with PHPT, PTX issuperior to ow risedronate, in terms of improvement of trabecular mineralization and vBMD at the tibia, while the effect at cortical sites is less pronounced.
Εισαγωγή : Eίναι γνωστό ότι ο πρωτοπαθής υπερπαραθυροειδισμός (ΠΥ) είναι σήμερα μία από τις συχνότερες ενδοκρινολογικές αιτίες δευτεροπαθούς οστεοπόρωσης, ακόμα και σε ασυμπτωματικούς ασθενείς, με μεγαλύτερη επίπτωση στον μετεμμηνοπαυσιακό πληθυσμό. Η διεθνής βιβλιογραφία αποδεικνύει ότι ο αυξημένος οστικός ανασχηματισμός, που είναι ένα από τα σημαντικότερα στοιχεία της νόσου, ευθύνεται μάλλον κατά ένα μέρος για τον αυξημένο καταγματικό κίνδυνο που τη χαρακτηρίζει. Ευρύ παραμένει ακόμα το πεδίο διερεύνησης για τους υπόλοιπους παράγοντες κινδύνου που επηρεάζουν και μεταβάλλουν την οστική κατάσταση (για παράδειγμα ογκομετρική οστική πυκνότητα – vBMD - και γεωμετρία σε σχέση με τη θεραπευτική επιλογή) και επομένως μπορεί να τροποποιούν την καταγματική αντοχή. Σκοπός : Ήταν η εκτίμηση στη μελέτη μας της vBMD και γεωμετρίας της αριστερής κνήμης χρησιμοποιώντας pQCT, καθώς και βιοχημικών παραμέτρων του ΠΥ όπως και η συσχέτιση των δεδομένων μεταξύ τους, συγχρόνως, σε δύο ομάδες μετεμμηνοπαυσιακών ασθενών, που η πρώτη (ομάδα 1) υποβλήθηκε σε εκλεκτική αφαίρεση παραθυροειδών και η δεύτερη (ομάδα 2) έλαβε ριζενδρονάτη προς αντιμετώπιση της νόσου.Υλικό και Μέθοδος : H έναρξη της μελέτης που πραγματοποιήθηκε το 2006, περιλάμβανε τους νεοδιαγνωσθέντες ασθενείς που προσήλθαν για ιατρική βοήθεια στο Εργαστήριο κατά τη διάρκεια ενός έτους. Στο συγκεκριμένο χρονικό διάστημα συνολικά 75 άτομα βρέθηκε να πάσχουν από ΠΥ. 20 αποκλείσθηκαν λόγω λήψης φαρμάκων - διφωσφονικά (15), κορτικοειδή (3), διουρητικά της αγκύλης (2) - και 5 έπασχαν από νόσο του συνδετικού ιστού ενώ 10 ασθενείς δεν έχρηζαν αντιμετώπισης και τέθησαν σε παρακολούθηση. Η απόφαση για την υποβολή των μισών ασθενών σε χειρουργική επέμβαση αφαίρεσης παραθυρεοειδών στηρίχθηκε αυστηρά στα κριτήρια του διεθνές συμποσίου του Εθνικού Ινστιτούτου Υγείας των ΗΠΑ…

▼ Background
Since the 1850s, parathyroid surgery continues to evolve through
improved understanding of the pathophysiology. Dialysis dependant
end stage renal failure (ESRF), the major cause of secondary
hyperparathyroidism continues to rise in the western world. Other
than renal transplantation, parathyroidectomy may provide a
substantial cure for longstanding renal hyperparathyroidism in
dialysis dependant patients. In 2004, cinacalcet was introduced
as an alternative to the surgical management of renal
hyperparathyroidism. However, cinacalcet was withdrawn from
Australia’s Pharmaceutical Benefits Scheme (PBS) in 2015, as
the EVOLVE study failed to demonstrate a statistically
significant reduction in the time to death, or non-fatal
cardiovascular events in those treated with cinacalcet with renal
hyperparathyroidism. This led to a re-emergence in
parathyroidectomy. Additionally in our institution, patients who
had been on cinacalcet, and subsequently underwent
parathyroidectomy because of refractory disease or intolerance to
cinacalcet, were noted to experience greater hyperkalaemia and
hypocalcaemia in the intraoperative and immediate postoperative
period.
Aims
• To review the engrossing history of the discovery and
progression of parathyroid surgery since the 19th century;
• To correlate the embryology, anatomy, histology, physiology
and pathophysiology of parathyroid glands in end stage renal
failure;
• To provide up to date review in regards to investigation and
the surgical management of renal hyperparathyroidism;
• Conduct a cohort study on the association of cinacalcet use
with greater likelihood of intraoperative and immediate
postoperative hyperkalaemia and hypocalcaemia following
parathyroidectomy in renal hyperparathyroidism.
Methods
Literature reviews utilizing MEDLINE and Cochrane review
databases, life science journals and textbooks were utilized.
Hospital medical records from The Canberra Hospital were studied
to collect data on the cohort case series. Analysis of data was
performed using SPSS Statistics and Microsoft Excel.
Results
Sir Richard Owen is reputed to be the first person to discover
the existence of parathyroid glands when examining a rhinoceros
in 1852. In the spirit of mortui vivos docent, Captain Charles
Martell in the 1930s had significantly increased our
understanding of the existence of ectopic locations of
parathyroid glands, as well as operative planning. The physiology
and pathophysiology of parathyroid glands in chronic renal
failure is multifaceted, with a complex interplay between bone,
kidneys, intestine, vitamin D, potassium, phosphate and
magnesium. There are a range of investigative strategies for
localizing parathyroid glands, often yielding greater sensitivity
and specificity when…

▼ Introduction:
Since the introduction in the 1970s of the unilateral approach in surgery for primary hyperparathyroidism by Wang, authors have increasingly been recommending limited forms of parathyroid surgery. Although unilateral explorations reduce operation time and admission days, decrease operative risk and give better cosmetic results, the debate about the best surgical treatment for primary hyperparathyroidism has never been settled. Bilateralists oppose less invasive approaches because they estimate the incidence of multiple gland disease to be as high as 30%. However, in spite of a systematic bilateral exploration of the neck in search of the diseased parathyroid gland, with identification and estimation of the size of all parathyroid tissue, in only 44% of cases are four glands identified, in 37% three, and in 19% less than three.
In chapter 1 we reported an exceptional case of persistent hyperparathyroidism (due to a non-descended inferior parathyroid) after extensive bilateral exploration, illustrating a clinical dilemma that can be encountered in parathyroid surgery. Imaging carried out prior to re-exploration and including, among other methods, ultrasonography and computed tomography, revealed a parathyroid adenoma at the level of the mandibular angle and the hyoid bone. Guided by the imaging results the adenoma was successfully resected by a local direct procedure taking less than 10 minutes.
In general, the main reason an adenoma is not found during exploration is the variability in location, rather than variety in the number of glands. It is therefore of pivotal importance to understand not only the anatomy, but also the embryology of the parathyroid glands. As radiologist John Doppman succinctly stated, If you are an experienced parathyroid surgeon and not able to find a tumor, you cannot have looked high enough.
Since primary hyperparathyroidism can be diagnosed with nearly 100% accuracy and successfully treated in more than 95% of cases, surgery is the treatment of choice. The gold standard in parathyroid surgery has been conventional neck exploration (CNE), and with success rates exceeding 95% and virtually no complications nothing more seemed left to be desired. However, it cannot be denied that there is a discrepancy between the extent of the operation and the size of the offending gland in the majority of patients. Encouraged by the pace of development in methods of imaging (resulting in increased accuracy), combined with the knowledge that primary hyperparathyroidism is caused by a solitary adenoma in at least 85% of cases, and our experience of the relatively simple and quick MIA procedure (chapter 1) we wondered whether such a direct, minimally invasive strategy could be utilized for the more common cases of primary hyperparathyroidism as well.
For this purpose we formulated the following hypothesis (chapter 3): A substantial group of patients with primary hyperparathyroidism can be successfully treated by limited access surgery after preoperative localization studies and may thus be…
