P061 Impact of Inflammatory Bowel Disease on sleep quality in a Mexican population attended in a referral center

BACKGROUND: Sleep disorders occur recurrently in patients with inflammatory bowel disease (IBD). The relationship between poor sleep quality and IBD activity has been subject to scarce attention. Poor sleep quality could be considered a relevant extraintestinal manifestation and a potential marker of subclinical inflammation, which could increase the severity of inflammation and the risk of relapse, however, we do not have enough information to confirm this hypothesis. Objective: Describe the impact of IBD on the quality of sleep, in patients treated in a referral hospital. METHODS: Observational, analytical, and cross-sectional study. Patients with diagnosis of IBD treated at Centro Médico Nacional "20 de Noviembre" were evaluated. The Pittsburgh Sleep Quality Index (PSQI) was used to measure sleep quality. IBD activity was measured using the Harvey-Bradshaw index for Crohn's disease (CD) and the Mayo scale for Ulcerative Colitis (UC). RESULTS: A total of 51 patients were included, the Pittsburgh Sleep Index Questionnaire (PSQI) was performed, after informed consent was signed. Patients had a mean age of 52. Fifty five percent were female, 65% had UC. Biological therapy was administered to 70.5%. In CD 89% were in remission and 11% in moderate activity. In UC 48.5% were in remission, 45.5% had mild activity and 6% had moderate activity. Eighty percent of the patients did not use hypnotic drugs. Patients with UC in remission had a bad perception of sleep quality in 68%, quite good sleep quality in 18% and very good sleep quality in 12% with a PSQI of 10.5 ± 3.2. In patients with mild activity, the perception of sleep quality was very good in 6%, quite good in 46%, quite bad in 40% and very bad in 6%, with a PSQI of 8 ± 3.7. In patients with moderate activity, 100% had a rather bad perception of sleep quality with a PSQI of 11 ± 1.4. For CD in remission the perception of sleep was quite bad in 43%, quite good in 43%, very bad in 6% and very good in 6% with a PSQI of 9 ± 4.3. In patients with moderate activity 50% had a very bad sleep quality perception and 50% a fairly good sleep quality perception with a PSQI of 14 ± 4.2. CONCLUSION: In this study a statistically significant association was obtained between PSQI and the perception of sleep reported by the patients, with a p < 0.005. Further research is still needed to better characterize sleep disturbances in this population. Due to the sample size, a prospective, randomized study is required to confirm these findings. The present analysis has no conflict of interest.
