Nutritional Rehabilitation in Patients with Malnutrition Due to Crohn's Disease.

BACKGROUND: Crohn's disease (CD) is a chronic inflammatory bowel disease frequently associated with malabsorption and secondary protein-energy malnutrition (PEM). METHODS: Biochemical and clinical data of 63 (34 females, 29 males) patients with PEM due to CD sent to our outpatient unit for nutritional evaluation were retrospectively analyzed. Patients were divided into two groups, according to disease activity. Thirty-eight patients (group A) had the active disease, and 25 patients (group B) suffered from malabsorption resulting from past intestinal resections due to CD. After a physical and hemato-biochemical evaluation at the first visit, all patients received disease-specific personalized dietetic indications. When indicated, oral nutritional supplements, oral/parenteral vitamins, micronutrients, and electrolytes, up to parenteral nutrition, were prescribed. RESULTS: After 1, 3, and 6 months of nutritional therapy, body weight, body mass index (BMI), and serum butyryl-cholinesterase significantly improved in both groups. In 8 out of 13 (61.5%) patients with a cutaneous stoma, intestinal continuity was restored. CONCLUSIONS: This study confirms the effectiveness of nutritional rehabilitation and provides information on the time required for nutritional treatment in patients with CD, both during the acute phase and after malabsorption due to intestinal resection.

Long-term medical complications after malabsorptive procedures: effects of a late clinical nutritional intervention.

OBJECTIVE: The growing prevalence of severe obesity, combined with the failure of conservative treatments, has led to a significant spread of bariatric surgical procedures. The aim of this study was to emphasize the need of adequate presurgery patient selection and close follow-up after malabsorptive procedures for bariatric surgery. METHODS: The study retrospectively evaluated 25 (20 F, 5 M; mean age 43 ± 13 y) obese patients (mean weight before intervention 134 ± 30.7 kg, body mass index 50.7 ± 10.1 kg/m(2)) attending our outpatient clinical nutrition unit for severe malabsorption and secondary malnutrition after surgical intervention that had been performed outside the regional area. RESULTS: All patients received personalized dietetic indications; in 12 of 25 (48%) cases integrated by oral protein supplements and in 5 of 25 (20%) by medium chain triglycerides. According to screening exams, patients were prescribed oral/parenteral iron, vitamins A, B group, D, and folate supplementation. In 14 of 25 (56%) patients, parenteral hydration and in 4 of 25 (16%), long-term parenteral nutrition was required. Five patients required hospitalization for severely complicated protein-energy malnutrition. CONCLUSION: Nutritional deficiencies are common after malabsorptive procedures for bariatric surgery; these can be present or latent before surgery, frequently going unrecognized and/or inadequately treated particularly when patients are not strictly followed up by the operating center. Despite the adequate-even intensive-intervention, clinical nutritional status moderately improved in all patients.
