De novo diabetic glomerulosclerosis in a renal allograft recipient.

Posttransplant diabetes mellitus is a well-recognized complication of renal transplantation. Although such patients are at risk for the development of de novo diabetic glomerulosclerosis with increasing graft survival, this has rarely been reported. We describe a patient with posttransplant diabetes mellitus who developed end-stage renal failure due to diabetic glomerulosclerosis 12 years after renal transplantation.

Bilateral renal angiomyolipomatosis in tuberous sclerosis presenting with chronic renal failure: case report and review of the literature.

A 45-year-old patient with tuberous sclerosis and bilateral renal angiomyolipomas who presented with chronic renal failure is reported. Although bilateral renal angiomyolipomas are commonly associated with tuberous sclerosis, the occurrence of chronic renal failure in the absence of associated cystic disease of the kidneys as seen in this patient is very rare.

Spectrum of dermatological lesions in renal allograft recipients in a tropical environment.

A total of 157 renal allograft recipients were followed for over 1-23 months for the development of dermatological lesions. The non-infective lesions related to immunosuppressive drugs included cushingoid features in 133 (84.7%), xerosis in 120 (76.4%), striae in 69 (43.9%), hypertrichosis in 65 (21.6%), facial erythema in 42 (26.7%) and friable skin in 34 (21.4%) patients. Of the infective lesions, cutaneous mycoses were the most frequent (82.6%) and included tinea corporis and cruris in 82 (52.2%), tinea versicolor in 21 (13.3%), candidiasis in 7 (4%), onychomycosis in 4 (2%) and cryptococcosis in 2 (1.2%) patients. Viral infections included those due to herpes zoster in 17 (10.8%), herpes simplex in 5 (3.1%) and viral warts in 13 (8.2%) patients. Cutaneous malignancy was seen in 1 patient only.

Acute renal cortical necrosis--a study of 113 patients.

Over a 28-year period, 113 out of 2986 (3.8%) patients dialysed for acute renal failure at a referral center in North India were diagnosed to have acute renal cortical necrosis (ACN). Obstetric causes were responsible for ACN in 56.6% patients and nonobstetric causes in 43.4%. Within the obstetric group, ACN developed in association with complications of late pregnancy in 37.1% and following septic abortion in 19.5%. The various nonobstetric causes included viperine snake bite in 14.2%, hemolytic uremic syndrome in 11.5%, renal allograft rejection in 5.3%, acute gastroenteritis in 4.4%, acute pancreatitis in 3.5%, septicemia in 2.7%, and trauma and drug-induced IV hemolysis in 0.9% patients. Total anuria was the commonest presenting feature and was noted in 78.8% of patients. Renal histology showed diffuse cortical necrosis in 62.8% and patchy lesions in 37.2% patients. Computerized tomography (CT scan) of the kidneys revealed characteristic diagnostic findings in all the 5 patients in whom it was done. Dialytic support could be withdrawn as a result of improvement in renal function in 19 patients with patchy cortical necrosis. Dialysis-free survival of as long as 12 years has been recorded. The present study shows that, in contrast to the Western world, ACN continues to be a common cause of acute renal failure in developing countries. CT scan of the kidneys is helpful in establishing an early diagnosis.

Postheparin lipolytic activity in acute and chronic renal failure.

Lipid profile and postheparin lipolytic activity (PHLA) were investigated in 21 patients with acute renal failure (ARF), 24 with chronic renal failure (CRF), and 23 healthy volunteers. Plasma triglycerides were significantly elevated in ARF (155.19 +/- 72.39 mg/dL) as well as CRF (166.79 +/- 72.36 mg/dL), as compared to controls (89.91 +/- 23.41 mg/dL, p < .001). PHLA was determined at 5, 10, 30, and 60 min after intravenous heparin (100 U/kg) and was observed to be reduced in ARF (7.82 +/- 1.41 mumol FFA/mL/h) as well as CRF (8.44 +/- 1.68 mumol FFA/mL/h) at 10 min, as compared to the values in the control subjects (12.03 +/- 2.43 mumol FFA/mL/h, p < .01). No correlation was found between PHLA and plasma triglycerides in ARF or CRF. In 15 patients in each group, PHLA subfractions, hepatic triglyceride lipase (HTGL), and lipoprotein lipase (LPL) were determined at similar time intervals after heparin. Both fractions were found to be reduced significantly (p < .01) in ARF as well as in CRF versus controls. These findings indicate that the lipid alterations in acute and chronic renal failure share common features including hypertriglyceridemia and reduced PHLA and its subfractions HTGL and LPL.

Acute renal failure in a case of fatal chromic acid poisoning.

Despite its frequent use in industry, acute poisoning by chromic acid has very rarely been reported. We report a patient who developed massive gastrointestinal hemorrhage, acute renal failure, and hepatic injury following chromic acid ingestion, and subsequently died. Postmortem liver and kidney biopsies revealed centrilobular necrosis and severe acute tubular necrosis, respectively.

Esophageal candidiasis after renal transplantation: comparative study in patients on different immunosuppressive protocols.

OBJECTIVES: The incidence of esophageal candidiasis (EC) in renal allograft recipients has not been well documented. The present study was done to determine the incidence of EC in renal allograft recipients receiving different forms of immunosuppressive therapy and to identify patients at a high risk of developing Candida esophagitis. METHODS: We conducted a retrospective study of 265 live related renal allograft recipients and compared three groups: patients given azathioprine and prednisolone (group I), those given cyclosporine, azathioprine, and prednisolone (group II), and those given cyclosporine and prednisolone (group III). EC was diagnosed by esophagogastroduodenoscopy. RESULTS: The overall incidence of EC was 10.5%. Group II patients had a significantly higher incidence (28.6%) than those in group I (10.4%) and group III (3.8%). EC was noted earlier in patients in groups II and III, who were on higher doses of steroids than group I patients. Dysphagia (57.1%) was the most common presenting symptom of EC, but 21.4% of patients were asymptomatic. Oral thrush was present in 42.9%. The entire esophageal mucosa was affected in six (46.1%) patients in group II and one (20%) in group III. No correlation was found between fungal serology or daily dose of steroids and extent of esophageal involvement. Treatment included nystatin in seven, nystatin and ketoconazole in 10, ketoconazole alone in eight, amphotericin B in one, and ketoconazole and amphotericin B in two episodes. Treatment failure occurred in seven (25%). Three patients died of disseminated candidiasis. Serology and biopsy were poor predictors of dissemination. CONCLUSIONS: In this retrospective study of renal allograft recipients, patients on triple drug immunosuppression, diabetics, and those with myelosuppression had an increased risk of developing EC. This high incidence calls for prophylactic use of antifungal agents in selected renal transplant recipients.

Pancreatic pseudocyst. A rare complication of polyarteritis nodosa.

An 18-year-old male who developed a pancreatic pseudocyst during the active phase of polyarteritis nodosa is described. Cytotoxic therapy with cyclophosphamide and prednisolone was unable to control the manifestation of this disease, and he required percutaneous drainage of the pseudocyst. The drainage resulted in complete resolution.

Renal mucormycosis: computerized tomographic findings and their diagnostic significance.

Isolated renal involvement by mucormycosis has been reported rarely in immunocompromised individuals. We describe four patients with mucormycosis confined to the kidneys, three of whom did not exhibit any predisposing factors. Only one patient had acute viral hepatitis with fulminant hepatic failure as the preceding disease. Two patients presented with oliguric renal failure of undetermined etiology and investigations revealed bilateral extensive involvement of the kidneys. Computerized tomography showed diffuse enlargement of the kidneys and multiple low-density areas. Treatment included systemic amphotericin B therapy in all four patients and nephrectomy in three patients. Two patients recovered completely. Our experience emphasizes the need for a high index of suspicion and recognition of computed tomographic scan appearances for making a prompt diagnosis. Early surgical intervention and systemic antifungal therapy are necessary for survival in this life-threatening condition.

Hereditary nephritis (Alport's syndrome)--clinical profile and inheritance in 28 kindreds.

Sixty-three patients, (52 males and 11 females) from 28 kindreds of hereditary nephritis (Alport's syndrome) were identified over a 14-year period from 1977 to 1991. Group I included 51 patients with (a) positive family history of haematuria with or without chronic renal failure, (b) characteristic GBM changes on electron-microscopy, (c) characteristic ocular signs, and (d) high-frequency sensorineural deafness. Group II included 12 patients with a negative family history. All of them had evidence of renal disease with characteristic ocular signs and deafness and four had characteristic GBM changes on electron-microscopy. The main clinical features were haematuria in 96.8%, deafness in 82.5%, and diminished visual acuity in 66.7% of affected subjects. Hypertension was present in 71.4% patients. Pure tone audiometry revealed high-frequency sensorineural deafness in 96.8%. Ocular examination showed bilateral anterior lenticonus in 37.8%, retinal flecks in 22.2%, cataract in 20%, and keratoconus in 6.7% patients. Proteinuria (> 2.0 g/24 h) was detected in 31.8%. Sixteen (57.1%) of the 28 index patients (all males) were diagnosed for the first time when they presented with end-stage renal disease. Serum creatinine in the overall group ranged from 0.9 to 18.7 mg/dl(7.81 +/- 5.37 mg/dl). Adequate renal tissue was obtained by biopsy in 14 patients. Light-microscopy revealed focal segmental glomerulosclerosis in five, mesangial proliferation in four, chronic interstitial nephritis in three, and mesangiocapillary and crescentic glomerulonephritis in one each. Electron-microscopy showed characteristic changes in the GBM in seven specimens.(ABSTRACT TRUNCATED AT 250 WORDS)

Corticotropin-dependent Cushing's syndrome in a patient with chronic renal failure--a rare association.

Corticotropin-dependent Cushing's syndrome was detected in a 32-year-old male suffering from membranous nephropathy and chronic renal failure. Cortisol dynamics revealed high basal cortisol, loss of circadian rhythm, and nonsuppressibility with low-dose dexamethasone. However, the latter was suppressible with high-dose dexamethasone. Treatment with ketoconazole led to a remarkable response both clinically and biochemically. The occurrence of Cushing's syndrome in a patient with chronic renal failure is extremely rare and poses significant diagnostic and therapeutic problems.
