An unexpected presentation: Minimal change disease in an adult with treatment-naïve hepatitis C

Minimal change disease is the most common glomerular disease affecting children; its prevalence among adults, however, is eclipsed by other glomerular pathologies. Each of these diseases has a number of classic associations, such as membranoproliferative glomerulonephritis with hepatitis C. We report the case of a middle-aged African-American male who presented with the nephrotic syndrome and acute renal failure and was concomitantly diagnosed with a new hepatitis C infection. He also had a history of urethral strictures with potential reflux nephropathy, which - in combination with his African-American race - also made focal segmental glomerulosclerosis a diagnostic possibility. Full laboratory evaluation did not distinguish the cause of his massive proteinuria; subsequent renal biopsy ultimately revealed minimal change disease. A full course of high-dose steroids eventually reduced his proteinuria, after which his renal failure resolved as well without need for hemodialysis.
