The Gut-Renal Connection in IgA Nephropathy
Summary: The connection between a dysregulated gut-associated lymphoid tissue and IgA nephropathy (IgAN) was supposed decades ago after the observation of increased association of IgAN with celiac disease. Pivotal studies have shown a role for alimentary antigens, particularly gliadin in developing IgAN in BALB/c mice, and a reduction in IgA antigliadin antibodies and proteinuria was reported after gluten free-diet in patients with IgAN. Recently a genome-wide association study showed that most loci associated with IgAN also are associated with immune-mediated inflammatory bowel diseases, maintenance of the intestinal barrier, and response to gut pathogens.
