Remission of minimal change disease in Type 2 diabetes after streptococcus bacteremia.
A 41-year-old man with Type 2 diabetes developed sudden onset of nephrotic syndrome. He initially refused a renal biopsy. However, 3 months later, the nephrotic syndrome persisted and percutaneous renal biopsy was performed. The study with light microscopy, immunofluorescence and electron microscopy showed minimal change disease. Three weeks after biopsy, before immunosuppressive therapy was begun, the patient presented Group A Streptococcus (GAS) bacteremia and acute renal failure which needed hemodialysis. Afterwards, the renal function recovered and complete remission of the nephrotic syndrome, maintained during a 22-month follow-up, was observed. We discuss the possible mechanisms implicated in the remission. This report extends the spectrum of infections associated with remission of minimal change disease (MCD).
