- Purpose: Short bowel syndrome (SBS) is the most common etiology for intestinal failure (IF) and these patients are at high risk of developing micronutrient deficiencies. This study aimed at assessing the level of vitamins in adult SBS patients at different stages of their disease before the initiation of multidisciplinary intestinal rehabilitation.
Methods: Patient data from November 2015 to March 2017 were retrospectively reviewed. Adult patients who underwent extensive bowel resection and were classified as SBS-IF were selected. Clinical data including age, sex, etiology of IF, biochemical data, nutritional status, nutrition support, and outcome of intestinal rehabilitation were analyzed.
Results: Nine patients with SBS-IF were included in the analysis. There were 6 male patients and 3 female patients, with a median age of 55.0 years. Vitamin levels were analyzed at 306 days (median) after the development of SBS. At the time of vitamin levels screening, 4 patients were receiving daily intravenous vitamin supplementation. Five patients were not receiving vitamin supplementations, either intravenously or orally. Vitamin B12 was within the normal range in 6 patients and higher than normal in 3 patients. Vitamin D was within the normal range in 3 patients and lower than normal in 6 patients. Vitamin E was within the normal range in 7 patients and higher than normal in 2 patients. Folate was within the normal range in 8 patients (not checked in 1 patient). Ambulatory patients had significantly higher vitamin D levels compared to hospitalized patients (P=0.015).
Conclusion: Vitamin D levels had decreased in 67% of patients with SBS in Korea, while vitamin B12, folate, and vitamin E deficiencies were rarely seen.
