Celiac disease associated membranous nephropathy - a rare cause or coincidence? A case report.

Introduction: Celiac disease is associated with a variety of autoimmune diseases such as type 1 diabetes mellitus, autoimmune thyroid disorders, Sjogren's syndrome and IgA nephropathy, however membranous nephropathy is not recognized amongst one of them.

Case Presentation: We report a rare case of nephrotic syndrome due to membranous nephropathy in a patient with celiac disease. A 77-years-old male patient presented with uncontrolled hypertension, anemia and acute renal failure.

Necrotizing and crescentic lupus nephritis with antineutrophil cytoplasmic antibody seropositivity.

Background And Objectives: Lupus nephritis is a classic immune complex glomerulonephritis. In contrast, antineutrophil cytoplasmic antibodies are associated with necrotizing and crescentic glomerulonephritis, in the absence of significant immune deposits. Antineutrophil cytoplasmic antibodies are detected by indirect immunofluorescence in 20% of patients with systemic lupus erythematosus.
