Glomerulonephritis as a variant of extra-intestinal manifestation of ulcerative colitis

Abstract

Studies of inflammatory bowel diseases (IBD), such as ulcerative colitis and Crohn's disease, is highly relevant due to their growing incidence and prevalence, and a wide range of extraintestinal manifestations. The paper deals with the discussion of renal damage types in IBD. Renal damage in IBD refers to rare cases of extra-intestinal manifestations and could both originate by the immunological mechanism common with IBD and directly related to inflammatory activity in the intestine, as well as be unrelated to the immunological activity of the bowel disease and be associated with metabolic disorders that develop in IBD. Finally, kidney damage in IBD can be caused by side effects of treatments. As an example, we present a case of mesangioproliferative glomerulonephritis as an extra-intestinal manifestation of ulcerative colitis and discuss the challenges of therapy and the effectiveness of genetically engineered biological agent golimumab. An algorithm for the differential diagnosis of the renal damage in patients with ulcerative colitis and Crohn's disease is proposed to be used in real clinical practice, with recommendations for monitoring of patients with IBD as those at risk for the development of chronic kidney disease.
