IgA Nephropathy in a Patient with Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is an autoimmune disorder. One of the most typical aspects of SLE is renal involvement. Lupus nephritis is a serious disease whose prognosis can usually be improved dramatically by treatment. The occurrence of non-lupus nephritis in SLE patients has rarely been reported. IgA Nephropathy (IgAN) and lupus nephritis (LN) have quite different laboratory, histopathologic findings and extra-renal clinical manifestations. In the light of these data we thought that IgAN and LN have different pathogeneses. We report a patient with SLE in whom IgA nephropathy was diagnosed.
