[Coeliac disease and membranous nephropathy].

Celiac disease results from the interaction between gluten and immune, genetic, and environmental factors. Although the main clinical manifestations are derived from gastrointestinal system, it has been described some renal diseases, especially chronic glomerulonephritis. We describe a young female patient with celiac disease that it appears after delivery. Moreover, she develops simultaneously nephrotic proteinuria and microhematuria as a result of membranous nephropathy. The treatment with gluten-free diet and other conservative measures (ACEI and statin) is followed by clinical improvement and simultaneous decrease of tissue antitransglutaminase IgA-antibodies and complete remission of proteinuria. We review the relationship between celiac disease and membranous nephropathy and the role of diet in the management of both diseases.
