IgA nephropathy (IgAN) is the most common primary glomerulonephritis worldwide. It is characterized by variability in its clinico-biological, histological and evolutionary manifestations.

The study included all patients with primary IgA nephropathy confirmed by renal biopsy.Two hundred and thirteen patients were included. The mean age at diagnosis was 34±12 years.
