IgA Nephropathy in an adolescent with juvenile systemic lupus erythematosus. A case report

Introduction: Juvenile systemic lupus erythematosus (JSLE) is a multisystem autoimmune disease characterized by the production of autoantibodies and the frequent development of immune complex-mediated glomerulonephritis. Lupus nephritis is a frequent and serious complication of JSLE, has a high associated morbidity rate, and is the cause of end -stage renal failure in many of these patients. IgA Nephropathy represents the most common etiology in the general population and is rarely associated with JSLE.Clinical case: a female adolescent with JSLE who was diagnosed with non-lupus nephritis (IgA nephropathy).Conclusions: The anatomopathological diagnosis is key to establish the prognosis and plan the treatment.
