Insulin-like growth factor-1 as a nutritional monitoring factor in patients with chronic intestinal failure.

Background & Aims: Nutritional monitoring plays an important role in optimizing nutritional support in patients with chronic intestinal failure (CIF) receiving long-term supplementation. Unlike initial nutritional assessment, however, there are no recommended guidelines for establishing a nutritional monitoring index. This study is to evaluate the suitability of insulin-like growth factor-1 (IGF-1) as a nutritional monitoring factor in CIF patients.
