Frail Phenotype in Patients With Inflammatory Bowel Disease.

BACKGROUND
Recent retrospective studies have shown that frailty is common in hospitalized patients with inflammatory bowel disease (IBD) and enhances the risk of drug-related infections, postsurgery complications, hospital readmissions, and mortality, independently of age and comorbidities. We carried out a descriptive cohort study to evaluate the frequency of frail phenotype in IBD and analyzed the risk factors associated with this condition.


METHODS
Frail phenotype was assessed in IBD patients by using the Fried frailty phenotype. Univariate and multivariate analyses were conducted to assess the risk factors for frail phenotype. Serum levels of interleukin (IL)-6 were quantified in patients with a frail or a fit phenotype by ELISA.


RESULTS
Three hundred eighty-six IBD outpatients (198 Crohn's disease and 188 ulcerative colitis) were prospectively enrolled from December 2021 to April 2022. Frail phenotype was diagnosed in 64 of 386 (17%) IBD patients and was significantly associated with female gender, active disease, and current use of steroids. Multivariate analysis showed that active disease was a risk factor for frail phenotype (odds ratio, 11.5; 95% confidence interval, 3.9-33.9). No difference in IL-6 serum levels was seen between patients with a frail phenotype and those who were fit.


CONCLUSIONS
This is the first prospective study showing that frail phenotype occurs in nearly one-fifth of IBD patients. Data indicate that active IBD is an independent risk factor for frail phenotype in IBD.
