Immunoglobulin A (IgA) nephropathy is characterized by IgA deposition in the glomerular mesangium and is one of the most common causes of glomerulonephritis and renal failure. The prevalence of IgA nephropathy is lower in the United States and in Europe, with higher rates in Asian countries. It is more common in Asian and White individuals than in Black individuals and is found predominantly in males in their 20s and 30s. About one quarter of patients with IgA nephropathy progress to end-stage renal disease (ESRD) within 10 years of initial diagnosis.

Treatment is based upon each patient's personal presentation, but all patients should be provided with supportive care to manage hypertension and proteinuria.
