Assessment of nutritional status in Crohn's disease in remission or low activity.
Malnutrition is frequently reported in chronic diseases with involvement of gastrointestinal tract, such as Crohn's disease; however, information about this problem is scarce, and available only for hospitalized patients with severe disease. The aim of this study was to evaluate the nutritional status of 44 consecutive outpatients with Crohn's disease in remission or in a stage of low activity (CDAI less than 250). Eighteen of the patients weighed less than 90% of ideal weight and 5 of these weighed less than 80%. Triceps skinfold, a measure of fat store, was less than or equal to 15th percentile in 30%; arm muscle circumference, indicative of muscle mass, was less than or equal to 15th percentile in 59%. The alteration of weight and arm muscle circumference was greater in patients with midly active disease (p less than 0.005) and in those with ileal and ileocolic involvement. Caloric intake, assessed by a seven day questionnaire, was generally good (35.9 +/- 11 Kcal/kg ideal weight/day) and sufficient to maintain weight. Creatinine height index was elevated in 55% of the whole group. Serum albumin was decreased in only 2 cases, and haemoglobin in only 4. Our results show that malnutrition is a serious problem also in outpatients with Crohn's disease. Anthropometric parameters are more sensitive indicators than conventional laboratory studies.
