Acute tubulointerstitial nephritis and anterior uveitis (TINU syndrome): a report of two cases.

TINU or Dobrin syndrome is a rare oculo-renal inflammatory condition which is comprised of acute idiopathic tubulointerstitial nephritis and uveitis. We report here two female patients aged 35 and 44 years, who were admitted with severe renal failure of acute onset (serum creatinine of 607 and 310 Umol/L [Editor note: do you mean "micromol/L"?] respectively) with the first patient requiring hemodialysis. The cause of acute renal failure was unclear on clinical and laboratory assessment, and a percutaneous renal biopsy was performed which showed features of acute tubulointerstitial nephritis in both cases. Both patients were started on oral steroids at a dose of 1 mg/kg/day. There was progressive improvement of their renal function. Three months later, the two patients presented with bilateral anterior uveitis requiring local corticosteroid therapy. This was followed by total resolution of the uveitis. The cause of the interstitial nephritis and the uveitis could not be identified in the two cases. The renal function was normal in these patients after 24 and 27 months of follow-up, respectively. Dobrin or TINU syndrome is rare, and must be considered in patients who present with acute tubular interstitial [Editor note: for consistency with the title, you may wish to replace this with "tubulointerstitial"] nephritis and anterior uveitis.

[Primary focal segmental glomerulosclerosis in adults: response to treatment and outcome]. / La hyalinose segmentaire et focale primitive de l'adulte: aspects thérapeutiques et evolutifs.

Response to therapy of primary focal segmental glomerulosclerosis (FSGS) in adults is poor, most studies demonstrated no response at all. We report our experience from a retrospective study about 22 adults patients. All patients presented proteinuria at admission with a nephrotic syndrome in 86 percent of cases. A high blood pressure was noted in 25 percent. A response to corticosteroid was obtained in 8 patients (36%) with complete remission in 5 cases (23%). Three patients were corticosteroid-dependant, two out of them went in remission under cyclophosphamide in one case and under chlorambucil in the other case. Fourteen patients did not respond to corticosteroids. Eight received cyclophosphamide with partial remission in 4 cases and progression to chronic renal failure (CRF) in 4 cases. The six non-responders did not receive immunosuppressive drugs because of severe CRF in 4 cases. The mean duration of follow-up was 39 months (20-55). The response to corticosteroid of primary FSGS in adults remain low (30%). The use of cyclophosphamide has improved the global remission to 50 percent.

[Ossifying fibroma of the face and hyperparathyroidism in a chronic hemodialysis patient]. / Fibrome ossifiant de la face et hyperparathyroïdie chez une hémodialysée chronique.

The bony complications in secondary hyperparathyroidism in chronic renal failure are varied. The ossifying fibroma is a rare manifestation. We report a case of a 40 years old woman with indeterminate nephropathy undergoing hemodialysis since 1982. Since may 1995, the patient had a diffuse and intensive bone pain of the two inferior members inducing functional importance with apparition of endobuccal tumefaction in the hard palate with an important increase of the volume of the maxillo-mandibular complex six months later associated to disturbances of the deglutition and phonation. In december 1995, the serum parathyroid hormone level is measured at 1527.6 pg/ml and the serum alkaline phosphatase level at 1620 UI/l. The bony lesions are disseminated to all the skeleton in the form of a demineralization with an ossifying expansive process affecting the maxillo-mandibular complex. Calcemia was at 2.3 mmol/l and phosphoremia at 2.1 mmol/l. The surgical biopsy of this pseudotumor showed an aspect of ossifying fibroma. The cervical echography showed a left inferior parathyroid nodular. In june 1996, a subtotal parathyroidectomy was done. The 9th day after surgery, the serum parathyroid hormone level was at 103 pg/ml with normal calcemia and phosphoremia. Five years later, the volume of the tumor reduced moderately. This observation induces 3 commentaries: the bony manifestations associated to secondary hyperparathyroidism have sometimes a tumoral aspect, the ossifying fibroma may be for known as well as the brown tumor and the treatment of these tumors in complex justifying furthermore a rigorous prevention of the hyperparathyroidism in hemodialyzed patients.

[Renal involvement in Behçet's disease. About six cases]. / L'atteinte rénale au cours de la maladie de Behçet. A propos de six observations.

PURPOSE: To analyze anatomoclinic and evolutive aspects of the renal involvement associated to the Behçet's disease through 6 observations collected in the nephrology department from 1985 to 2000 and to make a review of the literature. METHODS: Retrospective study, diagnosis of Behçet's disease according to the Classification of the International Group Study on the Behçet's disease and renal damage confirmed by histology. RESULTS: Our patients all male are aged between 25 to 55 years with a mean at 34 years old. The renal damage was revelated by a nephrotic syndrome in 3 cases and by a proteinuria at 1 to 2.7 g/day in 3 cases. Microscopic hematuria was present in 2 cases and arterial hypertension in 2 cases. The renal insufficiency has been noted in 2 cases of which severe in one of them. The renal biopsy showed an amyloidosis AA type in 3 cases, a segmental and focal glomerulonephritis in 2 cases and a thrombotic microangiopathy associated to a moderate tubulo-interstitiel lesions by toxicity of ciclosporine in 1 case. The extrarenal signs were dominated by bipolar aphtosis in all cases, necrotic pseudofolliculitis and the no specific cutaneous hyperreactivity in 5 cases and the erythema nodosum in 1 case. The ocular manifestation has been noted in 4 cases and articular manifestation in 3 cases. The vascular manifestation has been noted in one case. The treatment was colchicine in 4 cases and prednisone and cyclophosphamide in 1 case. Three patients were lost of view and a patient died in hemodialysis. The 2 other patients with amylosis had persistent proteinuria with a normal renal function. CONCLUSION: The kidney is one of organs that can alter the prognosis of the Behçet's disease; so, its screening must be realised in each patient with this disease.

[Obstetrical acute renal failure. Experience of the nephrology department, Central University Hospital ibn Rochd, Casablanca]. / Insuffisance rénale aiguë obstétricale. L'expérience du Service de néphrologie, Chu ibn Rochd, Casablanca.

The gravidic acute renal failure (ARF) becomes a rare complications of the pregnancy in the industrialized countries, whereas it is still frequent in the developing countries and responsible of great maternofetal morbidity and mortality. We studied the etiologic and evolutive aspects of the gravidic ARF in 55 patients during 18 years (1981-1998) at the department of nephrology, hospital center Ibn Rochd in Casablanca. The gravidic ARF represents 65% of the gravidic patients. The mean age of the patients is 30.92 +/- 6.44 years old. The mean parity is 3.38 +/- 2.25. The mean term is 31.73 +/- 10.02 weeks of amenorrhea. The main etiology is the preeclampsia and eclampsia, 41 patients (74.5%); the other causes are: the septic conditions: 6 patients (11%); the obstetrical hemorrhages: 4 patients (7.2%); the in uterofetal death: 3 patients (5.5%) and the post-cesarotomy: 1 patient (1.8%). 74.6% of the patients has been hemodialysed. The evolution has been characterized by the normal recuperation of the renal function is 48 patients (87.3%), a chronic renal failure in 2 patients (3.6%) and the death of 5 patients (mortality: 9.1%). The gravidic ARF is still a critical circumstances associated to a severe prognosis as well as in the woman and the fetus. So, the most effective measures are still the prevention and the managing of the obstetrical complications.

[Prevalence of subcutaneous, labial and rectal amyloid lesions in patients wi histologically confirmed renal amyloidosis]. / Prévalence des lésions amyloïdes sous-cutanée, labiale et rectale chez des patients ayant une amylose rénale confirmée histologiquement.

Our work is to evaluate the biopsies rectal (RB), cutaneous and one about the accessory salivary glands (ASGB) in the diagnosis of amyloidosis renal through 20 cases of renal amyloidosis confirmed by renal biopsy in unit of nephrology and hemodialysis in UHC lbn Rochd from February 1996 to January 1998. The mean age of our patients was 39 years old (15-80) with a male predominance of (4/1). The infectious pathology has been the most frequent cause (70%) which consisted essentially in the tuberculosis and the surinfection on dilatation of the bronchi. All the patients had nephrologic symptomatology dominated by the nephrotic syndrome. The 4 biopsies were practised in the 20 patients. Wright's reaction practised in all renal biopsy confirmed the AA nature of the amyloidosis. The amyloïd deposits were noticed in 100% of renal needle biopsy, 80% of accessory gland biopsy, 75% of rectal biopsy and in 35% of cutaneous biopsy. The association of RB and ASGB was positive in 90% of the cases. If the renal biopsy gave more positivity than the other biopsies, it caused complications that were severe sometimes. Also, the biopsy of the ASG, the simple technique is very reliable in the recognition of the amylosis and seems to be the best diagnostic test for this affection.

[Value of the biopsy of accessory salivary glands in amyloidosis]. / Intérêt de la biopsie des glandes salivaires accessoires dans l'amylose.

PURPOSE: To assess the value of accessory salivary gland biopsy for the diagnosis of amyloidosis, a study was conducted in the nephrology and hemodialysis department at Ibn Rochd University Hospital from February 1996 to January 1998. METHODS: Renal amyloidosis was confirmed by renal biopsy accompanying accessory salivary gland biopsy. RESULT: The patient's mean age was 39 years old (range 15-80), with a 4:1-male/female ratio. An infectious cause (either tuberculosis or superinfection and dilatation of the bronchi) was the most frequent (70% of the cases) etiology. All the patients presented renal symptomatology. Nephrotic syndrome predominated. Amyloid deposits were observed in 100% of renal needle biopsies and in 80% of accessory salivary gland biopsies. CONCLUSION: Renal biopsy led to more positive cases than the other biopsies. It may be accompanied by severe complications. Furthermore, biopsy of the accessory salivary glands is a simple and very reliable technique for the diagnosis of amyloidosis. It is currently the best diagnostic test.

[Arteriovenous fistula. Apropos of a local experience in Morocco]. / Les fistules artérioveineuses. A propos d'une expérience locale au Maroc.

During eleven years (1983-1994), 684 arteriovenous fistulas (AVF) were realized for 422 patients. The mean follow-up was 39 months. The most frequent AVF was Cimino and Brescia and the most frequent seat was radial. The failure rate in the immediate post-operative period was 10% and 8% after 48 hours. The permeability of the AVF was 59%, 51% and 42% at 1, 2 and 3 years. The late complications were thrombosis (28%), stenosis (15%) and false aneurysm (11%). In spite of recruiting patients with chronic renal failure and deficiency in hospital basic equipment, this experience permit us to start and then, to improve the activity of making AVF and to be able to pick-up patients with chronic renal failure.

[Tuberculosis in hemodialysis]. / La tuberculose des hémodialysés.

The authors report a retrospective study in order to illustrate the particular features of tuberculosis in hemodialysis population. Thirty two patients over 203 (15.8%) in periodic hemodialysis, have presented a tuberculosis between 1983 and 1996. There were 17 men and 15 women aged from 14 to 60 years old. The features of the tuberculosis in these cases were marked by the extrapulmonary localizations (50%) notably nodes tuberculosis, and the difficulties of the diagnosis certainty. The diagnosis was suspected basing on the fever, the weigh loss, the rate sedimentation increase and the radiologic lesions in pulmonary tuberculosis and peripheric or deep lymph nodes involvement. The diagnosis confirmation was established bacteriologically in 6 cases (18.7%) and histologically in 14 cases (43.8%). The treatment consisted on the association of isoniazide, rifampicin and pyrazinamide which leads to recovery in 87.5%. This treatment was a diagnosis proof in the absence of confirmation.

[Acute obstructive renal failure. Analysis of 28 cases]. / Insuffisance rénale aiguë obstructive. Analyse de 28 observations.

This retrospective study is concerned 28 patients hospitalized with acute obstructive renal failure at the department of nephrology in UHC Ibn-Rochd between 1988 and 1995. The objective of this study was to determine the clinical, étiological, therapeutical and evolutive aspects of the acute obstructive renal failure. It concerned 21 men and 7 women, their mean age is 52 years old. The main symptoms were anuria (85%) and lumbar pain (75%), the mean delay of consultation was 42 days. The diagnosis of the acute obstructive renal function and the presence of obstacle on the upper urinary tract. The obstacle was a stone in 19 cases, cancer in 8 cases and one case of retroperitoneal fibrosis was noted. Treatment of the cause was done whenever possible. Treatment was often palliative in the tumoral pathology. We observed 3 deaths (10.5%), 16 recoveries (58%), 6 cases of residual renal failure (21%), 3 cases of terminal chronic renal failure (10.5%) and 4 cases of recurrence. The lithiasic etiology of acute obstructive renal failure led to a high short-term mortality (15.5%), an effective etiologic causative treatment (69.5%) and a high rate or restoration of the renal function (69.5%). On the other hand, in the neoplastic etiology, there were no short-term mortality, but a frequent course to chronic renal failure.
