Background Nonthyroidal illness syndrome (NTIS) is prevalent in critical illness and is associated with poor outcomes. However, only few studies have focused on the relationship between NTIS and short‐bowel syndrome (SBS). The aim of this study was to investigate the prevalence, etiology, and prognosis of NTIS and its correlation with clinical variables in adult patients with SBS. Methods Sixty‐one eligible adults diagnosed with SBS, from December 2016 to December 2018, were retrospectively identified from a prospectively maintained database. Demographic and clinical characteristics (including thyroid hormones and nutrition variables) were evaluated for each participant. Results The prevalence of NTIS in adults with SBS was 52.5%. Patients with NTIS tended to have a longer duration of hospital stay and poor survival, but the results were not significant. A decreased, standard thyroid‐stimulating hormone index and sum activity of deiodinases and an increased secretory capacity by the thyroid were observed in the NTIS group. Receiver operating characteristic curve analysis showed that insulin‐like growth factor‐1 (IGF‐1) had better performance for distinguishing NTIS from patients with euthyroidism, with an area under the curve of 0.862 (cutoff, 101.0; sensitivity, 0.813; and specificity, 0.800). Conclusions NTIS is a common complication in adult patients with SBS. Patients with NTIS tend to have a worse nutrition status and poor prognosis. A potential pituitary thyrotroph dysfunction and hypodeiodination condition may play a role in the pathophysiology of NTIS in SBS. Furthermore, IGF‐1 is a meaningful predictor for distinguishing NTIS from euthyroid.
