Extraintestinal manifestations of inflammatory bowel disease.
Patients with inflammatory bowel disease (IBD) may confront a variety of nonintestinal problems. The first North American population-based data describing the incidence rates of several of these disorders have been reported over the past year. Reports have also documented our expanding knowledge of peristomal pyoderma gangrenosum, and of ulcerative colitis following liver transplantation in patients with primary sclerosing cholangitis. Osteopenia continues to receive considerable attention. Factors such as osteoprotegrin ligand, and its interaction with receptor activator of nuclear factor kappa B, are connected with T-cell activity, inflammation, and osteoclastogenesis. Studies in these and other areas are addressed in this review.
