Faecal clearance of α 1 ‐antitrypsin was measured in patients with ulcerative colitis and Crohn's disease and compared with disease activity and markers of protein‐calorie malnutrition. Patients with active ulcerative colitis and Crohn's disease showed elevated clearance of α 1 ‐antitrypsin and clearance declined in most patients with induction of remission. However, even with inactive disease, elevated protein loss persisted in some patients, presumably reflecting residual inflammation in the intestinal mucosa. There was a significant correlation between clearance of α 1 ‐antitrypsin and serum levels of retinol‐binding protein and transferrin in patients with ulcerative colitis and with retinol‐binding protein in patients with Crohn's disease. Clearance of α 1 ‐antitrypsin reflects disease activity in inflammatory bowel disease and correlates with serum levels of rapid‐turnover proteins such as retinol‐binding protein and transferrin, which are markers for the presence of protein‐calorie malnutrition.
