Autosomal dominant polycystic kidney disease with congenital absence of contralateral kidney.

Autosomal dominant polycystic kidney disease is the most frequent hereditary kidney disorder, accounting for 8-10% of the cases of end-stage renal disease. It is characterized by bilateral multiple renal cysts, nevertheless, asymmetric enlargement of the kidneys is frequently observed, and this can lead to diagnostic confusion. We report the rare occurrence of autosomal dominant polycystic disease confined to a right kidney and congenital absence of the contralateral one. Unexpected early onset of terminal renal failure in this hypertensive 23-year-old male is discussed with the review of the literature.

Postinfectious diffuse proliferative glomerulonephritis and acute renal failure in an HIV patient.

Postinfectious proliferative glomerulonephritis may occur in HIV-infected patients, although it is not a common cause of severe acute renal failure in them. We report a woman with HIV infection, who developed hypocomplementemic acute nephritic syndrome 10 days after an upper respiratory infection. Systemic diseases were excluded. The serum creatinine level increased to 6.6 mg/dl. Renal biopsy showed diffuse endocapillary proliferative glomerulonephritis, with mesangial and capillary walls, granular deposits of IgG and C3 by immunofluorescence. She was given corticosteroids with progressive normalization of her renal function. No opportunistic infections have occurred during 1-year follow-up.

Renal hypomagnesemia, hypercalciuria and nephrocalcinosis in a middle-aged man.

We report a 41-year-old man with hypomagnesemia, hypercalciuria, nephrocalcinosis, myopia and horizontal nystagmus. The hypomagnesemia was due to primary renal magnesium loss. He was diagnosed as having the syndrome of renal hypomagnesemia, hypercalciuria and nephrocalcinosis. This is a rare condition generally diagnosed by the first to third decades of life. Renal failure is common and end-stage renal disease can occur in children or young adults. The patient was treated with oral magnesium, chlorthalidone, potassium citrate and allopurinol and was followed up for 3 years. Treatment resulted in an improvement in hypercalciuria but serum magnesium level could not be normalized. The patient's renal function remains stable, with a mild degree of renal insufficiency.

Antiglomerular basement membrane antibody-crescentic glomerulonephritis complicating chronic bronchiectasis.

A 68-year-old woman with chronic bronchiectasis presented with haematuria and severe oligoanuric renal failure with no other serious systemic manifestation. Antiglomerular basement membrane (anti-GBM) antibodies and anti-myeloperoxidase antibodies were positive. Renal biopsy revealed anti-GBM crescentic glomerulonephritis. A conservative approach was followed and the patient is stable on chronic haemodialysis 6 months later. To the authors' knowledge, there has only been one previous report of anti-GBM disease complicating bronchiectasis.

[Extracapillary IgA nephropathy associated with infection with hepatitis C virus and hepatic cirrhosis].

We describe a 36 year old man who was admitted to the hospital with dyspnea, edema of the lower limbs, arterial hypertension and oliguric renal failure. He had microhematuria and nephrotic range proteinuria, immunological tests were normal or negative. Renal biopsy revealed global (55%) or segmental glomeruloesclerosis, remaining glomeruli showed extracapillary proliferation (25%). Immunofluorescence study disclosed IgA mesangial deposits. He was also diagnosed as having liver cirrhosis with positive serology against hepatitis C virus. He was treated with dialysis, antihypertensive drugs and steroids with improvement of the renal function. However, ten months later maintenance hemodialysis became necessary. We emphasize two points: first IgA glomerulonephritis is rarely associated with hepatitis C infection, and second crescentic IgA nephropathy has been infrequently reported in liver cirrhosis.

[Rhabdomyolysis and anuric kidney failure induced by the treatment with a gemfibrozil-cerivastatin combination].

A 67-year-old man treated with gemfibrozil for a year development rhabdomyolysis and anuric renal failure after addition of cerivastatin. The clinical features and serological studies ruled out other causes of rhabdomyolysis. Drugs were stopped and hemodialysis was carried on for 14 days until diuresis occurred. The renal function improved steadily to a serum creatinine of 1.2 mg/dl two months later. On the basis of its pharmacokinetic profile cerivastatin appears to have less interactions than other statins. There are only two reports of rhabdomyolysis and acute renal failure due to fibrates and cerivastatin combination. This patient shows the potential risk of a fibrates-cerivastatin combination. When this association is required it is necessary to avoid other nephrotoxic and myopathic factors and to monitor CK levels closely.
