Resume Introduction La povidone iodee est un antiseptique largement utilise surtout en usage cutane. Malgre son innocuite, des cas d’insuffisance renale aigue rentrant dans le cadre d’une toxicite a l’iode ont ete rapportes. Observation Une femme âgee de 37 ans, sans antecedents particuliers etait suivie pour une sterilite primaire de 4 ans. Elle a eu, dans le cadre de l’exploration de cette sterilite, une hysteroscopie avec opacification par de la povidone iodee. En post operatoire immediat, une insuffisance renale aigue oligurique s’est developpee. Apres traitement par diuretiques et 5 seances d’epuration extra renale, l’evolution etait favorable avec declenchement de la diurese a J18 suivi d’une normalisation de la fonction renale. Discussion La toxicite a l’iode est plus importante quand la povidone iodee est administree in situ au contact des muqueuses. L’insuffisance renale aigue est a type de necrose tubulaire aigue comme chez cette patiente. En l’absence d’autre cause, cette insuffisance renale aigue a ete rattachee a la povidone iodee. Conclusion L’insuffisance renale aigue secondaire a la toxicite a l’iode reste possible surtout si la povidone iodee est administree au contact des muqueuses. L’evolution est en general favorable apres l’arret du contact avec cet agent et le traitement symptomatique.

Resume Objectif Nous avons etudie les caracteristiques cliniques, therapeutiques et evolutives de la fibrose retroperitoneale. Methodes Nous avons analyse les observations de fibrose retroperitoneale diagnostiquees entre 1980 et 2002 dans notre hopital, a partir des resumes de 15 patients ayant une fibrose retroperitoneale (FRP). La surveillance therapeutique a ete fondee sur la biologie et la radiologie. Resultats Il s’agissait de 11 hommes et de 4 femmes dont l’âge moyen etait de 44,5 ans avec des extremes de 28 a 64 ans. Tous les malades avaient des douleurs essentiellement lombaires et abdominales. Un syndrome inflammatoire existait dans tous les cas et une insuffisance renale dans 11 cas. Les explorations radiologiques ont montre une hydronephrose uni ou bilaterale dans 14 cas et la plaque de fibrose dans 13 cas. Le traitement a ete constitue de corticoides seuls dans 9 cas, de chirurgie seule dans 3 cas et de chirurgie associee a la corticotherapie dans 3 cas. Dix rechutes a raison de 1 a 5 ont ete observees chez 4 malades apres arret des corticoides. Apres un delai moyen de suivi de 36 mois (18 j a 11 ans) 1 deces a ete observe, 12 patients avaient une fonction renale normale et 2 malades ont garde une insuffisance renale moderee. Conclusion Nous avons confirme la rarete de la fibrose retroperitoneale, la difficulte de son diagnostic, la frequence de la douleur, du syndrome inflammatoire et de l’insuffisance renale. Les corticoides sont efficaces et un suivi regulier est necessaire.

Cocaine is one of the most commonly used illicit drugs with distribution and consumption throughout the world. Acute renal failure associated with rhabdomyolysis, direct vasoconstriction and hemodynamic alteration is well described in patients with cocaine intoxication. Cocaine use is associated with high blood pressure and may rarely induce malignant hypertension associated with thrombotic microangiopathy. We report the case of a patient who developed malignant hypertension associated with thrombotic microangiopathy after chronic consumption of cocaine. A kidney biopsy revealed thrombotic microangiopathy with fibrinoid necrosis of arterioles and glomerular tufts. He required dialysis sessions. Cocaine-mediated endothelial injury and platelet activation may play important pathogenetic roles in cocaine abusers who develop malignant hypertension associated with thrombotic microangiopathy. Clinicians need to be aware of this rare feature of cocaine intoxication.

Renal involvement in Sjogrens syndrome (SS) is not uncommon and may precede other complaints. Tubulointerstitial nephritis is the most common renal disease in SS and may lead to renal tubular acidosis (RTA), which in turn may cause osteomalacia. Nevertheless, osteomalacia rarely occurs as the first manifestation of a renal tubule disorder due to SS. We herewith describe a 43-year-old woman who was admitted to our hospital for weakness, lumbago and inability to walk. X-ray of the long bones showed extensive demineralization of the bones. Laboratory investigations revealed chronic kidney disease with serum creatinine of 2.3 mg/dL and creatinine clearance of 40 mL/min, hypokalemia (3.2 mmol/L), hypophosphatemia (0.4 mmol/L), hypocalcemia (2.14 mmol/L) and hyperchloremic metabolic acidosis (chlorine: 114 mmol/L; alkaline reserve: 14 mmol/L). The serum alkaline phosphatase levels were elevated. The serum levels of 25-hydroxyvitamin D and 1,25-dihydroxy vitamin D were low and borderline low, respectively, and the parathyroid hormone level was 70 pg/L. Urinalysis showed inappropriate alkaline urine (urinary PH: 7), glycosuria with normal blood glucose, phosphaturia and uricosuria. These values indicated the presence of both distal and proximal RTA. Our patient reported dryness of the mouth and eyes and Schirmers test showed xerophthalmia. An accessory salivary gland biopsy showed changes corresponding to stage IV of Chisholm and Masson score. Kidney biopsy showed diffuse and severe tubulo-interstitial nephritis with dense lymphoplasmocyte infiltrates. Sicca syndrome and renal interstitial infiltrates indicated SS as the underlying cause of the RTA and osteomalacia. The patient received alkalinization, vitamin D (Sterogyl ®), calcium supplements and steroids in an initial dose of 1 mg/kg/day, tapered to 10 mg daily. The prognosis was favorable and the serum creatinine level was 1.7 mg/dL, calcium was 2.2 mmol/L and serum phosphate was 0.9 mmol/L.

Resume Introduction L’association d’une nephropathie amyloide avec une maladie inflammatoire intestinale chronique a ete observee chez 4 patients (maladie de Crohn dans 3 cas, rectocolite hemorragique dans 1 cas). Observations Ces patients âges en moyenne de 37 ans (24 a 48 ans) ont ete admis pour le bilan d’un syndrome nephrotique associe a une insuffisance renale dans 2 cas. L’exploration a conclu a une amylose de type AA dans tous les cas. Un patient a ete perdu de vue. Un patient a ete traite par la salazopyrine, un par des corticoides et un par la colchicine. Apres un suivi moyen de 16 mois (5-30 mois), l’evolution a ete marquee par l’installation d’une insuffisance renale terminale dans 1 cas, l’amelioration de la fonction renale dans 1 cas et le maintien d’une fonction renale normale dans 1 cas. Chez aucun des patients il n’y a eu remission du syndrome nephrotique. La reponse de l’amylose renale au traitement de la colite inflammatoire chronique est variable. Les corticoides et la colchicine ont permis de stabiliser la fonction renale chez 2 des patients mais sans remission du syndrome nephrotique. Commentaires L’amylose AA compliquant les maladies inflammatoires intestinales est rare. L’indication de la colchicine merite d’etre discutee, d’autant plus que le traitement de la maladie causale ne permet pas, dans la majorite des cas, la remission de l’amylose dont le pronostic est determine par l’atteinte renale.

Anemia is a frequent complication in patients with chronic kidney disease. However, human recombinant erythropoietin (rHu-EPO) has revolutionized the management of anemia in chronically dialyzed patients. Epomax ® is a new rHu-EPO alfa manufactured in Tunisia (Medis Laboratories). The aim of this study was to evaluate the efficacy and tolerance of Epomax ® in chronic hemodialysis (HD) patients in a phase-III, multicenter, clinical trial. Fiftythree HD patients (mean age 47.7 ± 13 years) who received a stable dose of rHu-EPO (Hemax ® , a rHu-EPO alfa manufactured by Biosidus Laboratories) subcutaneously were switched to Epomax ® via the same route of administration. At baseline, the mean systolic pressure was 132 ± 18 mm Hg and the mean diastolic pressure was 79 ± 8 mm Hg. The mean blood hemoglobin was 10.2 g/dL and the median ferritin level was 667 ng/mL. After a follow-up of 43 days, the mean blood hemoglobin was 10.5 g/dL under the effect of Epomax ® . There was no significant difference in the mean hemoglobin levels between the treatments with both drugs. Few adverse events were reported during the study. We conclude that Epomax ® was effective at maintaining the hemoglobin levels at target concentrations and was well tolerated in HD patients.

The incidence of tuberculosis (TB) is high in patients undergoing chronic dialysis than it is in the general population. The diagnosis of TB is often difficult and extrapulmonary involvement is predominant. This study investigates the spectrum of clinical presentations and outcome in dialysis patients during a nine-year period. TB was diagnosed in 41 patients. Anti-TB drugs, adverse effects of therapy, and outcome were noted. Thirty-eight patients (92.6%) were on hemodialysis and three were on peritoneal dialysis (7.3%). The mean age at diagnosis was 50.8 years and the male/female ratio was 1.16. Four patients had a history of pulmonary TB. Extrapulmonary involvement was observed in 32 (78 %) patients. The bacteriological confirmation was made in 41.46% and histological confirmation was made in 26.83%, and in the rest, the diagnosis was retained on the criterion presumption. Nineteen patients (46.34%) developed adverse effects of antitubercular drugs. Eight patients (19.51%) died during the study from TB or adverse effects of treatment. Low urea reduction ratio and female sex were associated with poor prognosis in our study. The clinical manifestations of TB in patients on dialysis are quite nonspecific, making timely diagnosis difficult, and delaying the initiation of curative treatment, which is a major determinant of the outcome.

Subcutis calcinosis, characterized by abnormal calcium deposits in the skin, is a rare complication of using calcium-containing heparin occurring in patients with advanced renal failure. We report the case of an 83-year-old female, a known case of chronic kidney disease (CKD) for four years with recent worsening of renal failure requiring hospitalization and hemodialysis. She developed subcutis calcinosis following injection of calcium-containing heparin. Biochemical tests showed serum parathormone level at 400 pg/dL, hypercalcemia, elevated calcium-phosphate product and monoclonal gammopathy related to multiple myeloma. She developed firm subcutaneous nodules in the abdomen and the thighs, the injection sites of Calciparin ® (calcium nadroparin) that was given as a preventive measure against deep vein thrombosis. The diagnosis of subcutis calcinosis was confirmed by the histological examination showing calcium deposit in the dermis and hypodermis. These lesions completely disappeared after discontinuing calcium nadroparin injections. Subcutis calcinosis caused by injections of calcium-containing heparin is rare, and, to the best our knowledge, not more than 12 cases have been reported in the literature. Pathogenesis is not well established but is attributed to the calcium disorders usually seen in advanced renal failure. Diagnosis is confirmed by histological tests. Outcome is mostly favorable. The main differential diagnosis is calciphylaxis, which has a poor prognosis. Even though rarely reported, we should be aware that CKD patients with elevated calcium-phosphorus product can develop subcutis calcinosis induced by calcium-containing heparin. When it occurs, fortunately and unlike calciphylaxis, outcome is favorable.

Introduction : l’infection a Cytomegalovirus (CMV) chez le patient transplante renal peut mettre en jeu le pronostic vital mais aussi la survie du greffon vu l’augmentation du risque de rejet aigu d’ou l’interet d’une prophylaxie. Methodes : nous rapportons une serie de 61 patients transplantes du rein et mis sous prophylaxie anti –CMV et nous etudions la prevalence de l’infection a CMV dans notre serie. Resultats : la prophylaxie anti–CMV proposee dans notre serie est la Valaciclovir (Zelitrex*) des J1 de greffe renale pendant 3mois si le profil CMV est D+ /R+ ou D-/R+ ou D-/R- et pendant 6 mois si D+/R. Nous realisons la serologie CMV a J1, J7 post greffe renale ainsi qu’au 3 eme mois, 6 eme et 12 eme mois apres la transplantation renale. Pendant la periode de l’etude qui s’etend de Decembre 2011 a Juin 2016, nous avons collige 2 cas d’infection a CMV soit 5%. Comme 1 ere observation; Il s’agissait d’un patient âge de 43 ans transplante renal par un donneur vivant apparente. Le profil CMV etait D+/R+. Apres la transplantation renale le patient a ete mis sous traitement prophylactique par Valaciclovir pris pendant 25 jours puis arrete par le patient. Il presentait 30 jours apres l’arret du Valaciclovir, une diarrhee avec fievre et a la biologie une leucopenie, une CRP elevee et une creatinine a 1,3 mg/dl. Une PCR CMV en temps reel est fortement positive. Le traitement par Ganciclovir a ete instaure avec evolution favorable et PCR CMV negative. A J21 de Ganciclovir on a note une aggravation de la leuco-neutropenie. Apres 12 jours d’arret de Ganciclovir, le taux de globules blancs est revenu a la normale spontanement. La deuxieme observation etait porte sur une Patiente A.N âgee de 41 ans, transplantee renale a partir d’un donneur vivant apparente et un statut serologique D+/R+ mise sous prophylaxie par Valaciclovir pendant 90 jours. Elle a presente une insuffisance renale aigue (IRA) (creatinine passant de 176 µmol/l a 316 µmol/l) a 3 mois post transplantation renale. La biopsie du greffon a montre un rejet aigue humoral Borderline et elle etait mise sous Rituximab et Immunoglobulines intra-veineuses. L’evolution etait marquee par la stagnation de la creatinine. Devant l’IRA, la leucopenie et la thrombopenie une PCR CMV a ete pratiquee revenue positive, et la patiente a ete traitee par Cymevan pendant 21 jours. L’evolution a ete marquee par la normalisation du bilan hematologique et l’amelioration de la fonction renale (creatinine = 132 μmol/l). Dans notre centre, nous preconisons la prophylaxie anti-CMV systematique par Valaciclovir. Le 1er cas d’infection a CMV que nous avons note est survenu chez un patient qui n’avait pas pris le Valaciclovir. Chez la deuxieme patiente, l’infection a CMV est survenue a l’arret de la prophylaxie dans un contexte de forte immunosuppression pour un rejet humoral. Conclusion : le faible effectif et le recul court dans notre etude ne permettent pas de conclure. Des etudes plus larges seront d’un grand apport.
