The Clinical Course of Mesangial Proliferative Glomerulonephritis

Patients with a pure mesangial proliferative glomerulonephritis may present with either hematuria, asymptomatic proteinuria, or nephrotic syndrome. For patients with hematuria, the clinical course is self-limited, and spontaneous resolution of recurrent episodes of macroscopic hematuria occurred in many of these patients. For patients with asymptomatic proteinuria, a spontaneous decrease in proteinuria occurred and none of these patients developed a progressive course. The clinical course of patients with nephrotic syndrome was similar to that usually observed in children and adults with pure minimal change lesions. A complete remission of the nephrotic syndrome occurred in most of these patients during treatment with prednisone and cyclophosphamide. Overall, the prognosis for the patients reported in this series was quite good.
