Selective immunoglobulin a deficiency, ulcerative colitis, and gluten-sensitive enteropathy--a unique association

Abstract

A patient with selective immunoglobulin A deficiency, severe ulcerative colitis, and malabsorption had a flat jejunal mucosa demonstrated by peroral biopsy. Treatment at different times with a gluten-free diet for the jejunal lesion and corticosteroids for the ulcerative colitis, led to improvement of the malabsorption. A repeat jejunal biopsy demonstrated histological improvement of the jejunal mucosa, even though the colitis remained active. The occurrence of immunoglobulin A deficiency in a patient with ulcerative colitis and gluten-sensitive enteropathy is uncommon.
