MEMBRANOUS GLOMERULOPATHY AND CHRONIC SMALL‐INTESTINAL ENTEROPATHY ASSOCIATED WITH AUTOANTIBODIES DIRECTED AGAINST RENAL TUBULAR BASEMENT MEMBRANE AND THE CYTOPLASM OF INTESTINAL EPITHELIAL CELLS

Abstract
A child with an immune-mediated disease is described, who presented two very rare clinical manifestations, a membranous glomerulopathy with circulating anti-renal tubular basement membrane antibody and a small-intestinal enteropathy with circulating antibody directed against the cytoplasm of intestinal epithelial cells. Steroid treatment was followed by complete resolution of the renal but not the intestinal manifestations.
