[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.
