INTRODUCTION Posttransplant diabetes mellitus (PTDM) is a common, serious complication of renal transplantation. The aim of this retrospective study was to estimate the incidence and to identify potential factors predisposing to PTDM. PATIENTS AND METHODS We evaluated 296 adult nondiabetic patients who underwent kidney transplantation at our center. PTDM was defined according to 2003 international consensus guidelines. Potential factors predisposing to PTDM were analyzed individually and simultaneously using a logistic regression model. RESULTS Over 2054.5 years of cumulative follow-up, 51 patients (17.2%) developed diabetes corresponding to an annual incidence of 2.5%. PTDM was diagnosed after a median of 2.9 months (range: 0.2-168). The mean age of affect individuals was 33.3±7.4 years. Patients with PTDM were significantly older (P<.0005) and showed an higher body mass index (BMI; P<.004). Univariate analysis revealed that age, BMI, family history of diabetes, vascular nephropathy, and hepatitis C infection were associated with PTDM. Multivariate analysis rescaled the roles of age (relative risk [RR]=1.046/y; P<.04), BMI (RR=1.107/kg/m2, P<.05), vascular nephropathy (RR=7.06, P<.03), and hepatitis C infection (RR=2.72, P<.03) as independent factors predisposing to PTDM. CONCLUSION Among our relatively young kidney transplant recipients, in whom only 8% received tacrolimus, PTDM was a frequent complication. We suggest that the use of oral glucose tolerance tests to screen patients identifies those predisposed to develop this complication.

L’ectopie thyroidienne est une pathologie rare (1/4000 a 1/8000 des patients atteints d’hypothyroidie) dont la pathogenie reste mal elucidee. Elle peut etre asymptomatique ou se manifester par une hypothyroidie clinique ou biologique. Nous rapportons deux observations d’ectopie thyroidienne diagnostiquees a un âge avance. La premiere est celle d’une patiente âgee de 20 ans connue hypothyroidienne depuis l’âge de 13 ans et qui a ete hospitalisee suite a l’arret de son traitement hormonal substitutif. A l’examen, la thyroide n’etait pas palpable et l’examen de l’arriere cavite buccale a montre une formation linguale posterieure. A la scintigraphie thyroidienne, cette formation correspond a une thyroide ectopique en position sublinguale. La deuxieme observation est celle d’une patiente âgee de 32 ans, hospitalisee pour exploration d’une hyperprolactinemie. A l’examen clinique, il y avait des signes d’hypothyroidie et la thyroide n’etait pas palpable. L’echographie cervicale a montre une loge thyroidienne vide mais a mi en evidence une formation sublinguale rappelant une thyroide ectopique. La scintigraphie thyroidienne, la tomodensitometrie et l’imagerie par resonnance magnetique cervicales ont confirme le diagnostic d’ectopie thyroidienne en position sublinguale. Les deux patientes ont ete mises sous traitement hormonal substitutif. Nous discutons dans cet article les particularites cliniques et radiologiques de nos observations, ainsi que les bases genetiques de cette pathologie ; et nous insistons sur la necessite d’evoquer ce diagnostic devant toute hypothyroidie associee a l’absence de palpation d’une glande thyroide en position normale meme chez l’adulte.

Background/Aims: The coexistence of triple A syndrome (AAAS) and congenital hypogonadotropic hypogonadism (CHH) has so far not been reported in the literature. This study aimed to characterize at the clinical and genetic level one patient presenting an association of AAAS and CHH in order to identify causal mutations. Methods: Clinical and endocrinal investigations were performed and followed by mutational screening of candidate genes. Results: At the age of 18, the patient presented sexual infantilism, a micropenis and gynecomastia. No mutation was revealed in GnRHR, TACR3/TAC3, PROK2/PROKR2 and PROP1 genes, except a homozygous intronic variation (c.244 + 128C>T; dbSNP: rs350129) in the KISS1R gene, which is likely nondeleterious. A homozygous splice-donor site mutation (IVS14 + 1G>A) was found in the AAAS gene. This mutation, responsible for AAAS, is a founder mutation in North Africa. Conclusion: This is the first report on a Tunisian patient with the coexistence of AAAS and CHH. The diagnosis of CHH should be taken in consideration in patients with Allgrove syndrome and who carry the IVS14 + 1G>A mutation as this might challenge appropriate genetic counseling.

H Cheikhrouhou; K. Khiari; Lotfi Cherif; I. Hadj Ali; M. Héni; H. Rajhi; N. Ben Abdallah

Les auteurs rapportent 3 cas de pheochromocytomes malins. Le diagnostic etait pose d’emblee dans un cas et lors d’une recidive 2 et 31 ans apres la chirurgie initiale dans les 2 autres cas. Les metastases hepatiques ont constitue une preuve formelle de malignite dans 2 cas, alors que la recidive locoregionale, l’envahissement du pilier du diaphragme et de la graisse avoisinante ont permis de suspecter la malignite dans le 3e cas. La grossesse a constitue une circonstance de decouverte du pheochromocytome dans un cas de neoplasie endocrinienne multiple de type 2A. L’association pheochromocytome et carcinome papillaire de la thyroide a ete retrouvee dans un cas. La chirurgie a ete le traitement considere dans les trois cas. L’evolution etait variable d’un cas a l’autre.

Abstract Introduction: Vasculitis is a rare complication of antithyroid drugs reported with propylthiouracil, carbimazole, methimazole and Benzylthiouracil. Benzylthiouracil –induced Vasculitis are often severe forms with renal or pulmonary involvement, which can be life-threatening if left untreated .We describe the clinical course and medical management of 2 cases of severe vasculitis with alveolar hemorrhage and renal involvement occurred in 2 patients with Graves’ disease treated by Benzylthiouracil . Cases report: A 36 and 33-year-old women with Graves’ disease developed alveolar hemorrhage and acute renal failure after respectively 36 and 144 months of Benzylthiouracil therapy. Kidney biopsy showed pauci-immune crescentic glomerulonephritis in the 2 cases. Anti Neutrophil Cytoplasmic Antibody (ANCA) was positive (P- ANCA in the first patient and c-ANCA in the second patient). The condition of the first patient improved when Benzylthiouracil was withdrawn associated with corticosteroids and immunosuppressive treatment after a follow up of 6 months. However, the second patient died by severe infection after the same treatment. Conclusion: Benzylthiouracil vasculitis is a serious complication but its prognosis is good if diagnosis and treatment are early. However mortality is related to risk of infection.

Pheochromocytoma is a rare tumor responsible for paroxysmal hypertension which is difficult to control. Diagnosis is important because it represents a curable form of hypertension. Few cases of pheochromocytoma patients with end-stage renal failure were reported in the literature. These cases are specially responsible for diagnosis and therapeutic problems. We report here a case of an end-stage renal failure patient who has pheochromocytoma, he was treated by automated peritoneal dialysis. The patient is a 47-year-old man who has an IgA glomerulonephritis. On peritoneal dialysis, his blood pressure level remains high despite four antihypertensive drugs association and adequate dialysis. Furthermore, the patient suffered from headaches, sweats and palpitations. This leads to suspect pheochromocytoma. Thus, urinary excretion rates of metanephrines and normetanephrines were high. Radiographic diagnosis tests were negative but MIBG scintigraphy was able to localise the tumor in the left suprarenal gland. He had coelioscopic left adrenalectomy without complications, microscopic studies showed an hyperplasia of the adrenal medulla. Soon after surgery his blood pressure was well controlled by one antihypertensive drug. We conclude that refractory hypertension, as a possible diagnosis, is uncommon in peritoneal dialysis patients. Pheochromocytoma must be eliminated by careful evaluation.

Ibtissem Oueslati; K. Khiari; Nejib Ben Abdallah

Sir, Ovarian hyperstimulation syndrome is most commonly an iatrogenic complication of exogenous gonadotropin administration for ovulation induction. Its clinical presentation varies from abdominal pain and bloating, nausea, vomiting, and ovarian enlargement to possibly life‐threatening conditions including renal failure, hypovolemic shock, adult respiratory distress syndrome, thromboembolism, and pericardial effusion.[1]

Introduction La prise en charge des patients diabetiques doit commencer par la prescription dietetique. Les objectifs de cette prescription sont fonction du type de diabete et de la presence ou non de complications degeneratives en particulier la nephropathie diabetique (ND). Le but de notre travail etait d’evaluer les apports alimentaires des diabetiques insuffisants renaux au stade d’hemodialyse (HD). Patients et methodes L’etude a porte sur 30 patients diabetiques insuffisants renaux hemodialyses chroniques (15 hommes et 15 femmes). Ces patients ont beneficie d’une evaluation du degre d’education nutritionnelle et d’une enquete alimentaire en utilisant la methode de rappel de 3 jours: un jour avant HD, le jour de l’HD et un jour apres. Resultats L’âge moyen de nos patients etait de 57,93 ans. Seulement 17 patients (56,67 %) ont recu une education dietetique. L’enquete alimentaire a montre que 73 % des cas presentaient un deficit de l’apport calorique le jour de l’hemodialyse. Ce pourcentage s’elevait a 90 % les autres jours. De meme, on a note un deficit de l’apport proteique chez 70 % des patients, un exces de l’apport glucidique chez 60 % des patients, un exces de l’apport lipidique dans 47 % des cas et des troubles des apports en oligoelements et en vitamines chez la majorite des patients. Conclusion Au stade d’hemodialyse, la prescription dietetique a pour but de prevenir la denutrition d’une part et d’eviter l’installation de certaines complications nefastes a savoir la retention hydro- sodee et l’hyperkaliemie d’autre part. Cependant, il faut insister sur l’importance de l’education nutritionnelle chez tout diabetique avant l’apparition de la nephropathie diabetique. Celle-ci doit etre depistee precocement puisque le regime alimentaire permet dans ce cas, en plus des autres mesures therapeutiques, de prevenir le passage en insuffisance renale. Declaration d’interet Les auteurs declarent ne pas avoir d’interet direct ou indirect (financier ou en nature) avec un organisme prive, industriel ou commercial en relation avec le sujet presente.

P163 Diabète et acromégalie

I. Ben Nacef; R. Ben Said; I. Ouslati; K. Khiari; N. Ben Abdallah

Introduction L’acromegalie est diabetogene du fait de l’insulinoresistance resultant de l’effet stimulant de la GH sur la neoglucogenese et la glycolyse hepatique. Le but de notre travail est d’etudier la prevalence des troubles de la tolerance glucidique (TTG) au cours de l’acromegalie et d’evaluer l’evolution apres traitement. Patients et methodes Etude retrospective sur 30 ans (1982 a 2012) ayant concerne 25 patients acromegales hospitalises dans le service de medecine interne A, unite d’endocrinologie de l’hopital Charles Nicole. Resultats Dans la population etudiee, l’âge moyen de nos patients etait de 45 ans, une predominance feminine etait notee avec un sexe ratio de 2,12. L’anciennete de la maladie etait de 4 ans. Le syndrome dysmorphique etait note dans 100 % des cas, Le diagnostic etiologique etait un macroadenome hypophysaire dans 84 % des cas et un microadenome dans 12 % des cas. 60 % (15/25) avaient un trouble du metabolisme glucidique a type d’intolerance au glucose retrouvee chez 4 patientes (16 %) et de diabete retrouve chez 11 patients (44 %). Apres traitement on a note une normalisation du bilan glucidique chez une patiente consideree en remission, une amelioration de l’equilibre du diabete chez 3 patients par contre le diabete a reste tres mal equilibre chez 3 patients dont la maladie est encore evolutive. Conclusion L’acromegalie est une maladie insidieuse pouvant etre precedee par des anomalies metaboliques dont le diabete sucre. Penser a l’origine secondaire du diabete pourrait rendre le diagnostic de l’acromegalie plus precoce et ameliorer sa prise en charge. Le controle des autres facteurs de risque atherogene s’impose pour eviter l’evolution vers les complications cardiovasculaires, premiere cause de mortalite de l’acromegalie.
