Sleep Disturbance in Inflammatory Bowel Disease Is Associated with Disease Activity and Adverse Outcome

There is growing evidence about the relationship between sleep quality (SQ) and disease activity in inflammatory bowel disease (IBD). This study aimed to identify the prevalence of sleep disturbance in IBD and its predictive factors and to assess its association with worse outcome.

IBD patients were prospectively enrolled. Clinical activity, inflammatory activity (high C-reactive protein or fecal calprotectin), and SQ (assessed using the Pittsburgh Sleep Quality Index) were evaluated, and logistic regression was used to identify predictors of poor SQ at baseline. The development of disability or disease progression at 6 months (surgery, hospitalization, development of stenosis, penetrating or perianal disease, steroid dependency, or start/change immunosuppression) was compared between patients with and without poor SQ.

Two hundred and five patients were enrolled, with 44.9% (n = 92) reporting poor SQ. On multivariate analysis, current smoking (OR 2.80), extraintestinal manifestations (OR 2.68), clinical activity (OR 3.31), and inflammatory activity (OR 4.62) were predictive factors of poor SQ. Cox proportional hazards model showed that poor SQ was predictive of worse prognosis at 6 months (HR 2.470).

There is a high prevalence of poor SQ in IBD patients, highlighting the importance of its inclusion in patient-reported outcomes. Sleep disturbance seems to have prognostic value in IBD.
