It can be associated with the development of autoimmune diseases both in adults and in children even though the exact pathophysiology is not fully defined.Case Presentation: We report here a case of a young patient who developed nephrotic syndrome secondary to membranoproliferative glomerulonephritis associated with the incidental finding of IgAD. We began corticosteroid therapy and angiotensin-converting enzyme inhibitor, and we observed partial remission of the nephrotic syndrome after about nine months; nonetheless, in the following follow-up visits, a progressive decline of renal function was found.Conclusion: Our case extends the spectrum of hitherto described glomerulonephritides associated with IgAD which were described until now.Keywords: membranoproliferative glomerulonephritis, IgA deficiency, nephrotic syndrome
