Association of gastrointestinal involvement and depressive symptoms in patients with systemic sclerosis

Methods. One hundred and fifty-two patients with SSc completed the UCLA SCTC GIT 2.0 and the Center for Epidemiologic Studies Short Depression scale (CES-D10). Patients were divided into depressed (CES-D epsilon 10) or non-depressed group (CES-D < 10) and compared using t-test or chi-square test. Multiple linear regression was used to determine associations between GI scales and depressed mood (CES-D). Results. Study participants were 84% female, 78% Caucasian and 40% had depressed mood (CES-D10 epsilon 10). Patients with depressed mood had statistically worse GI scale scores (except fecal soilage) and worse total GIT score (P < 0.05). In the multivariable model reflux and constipation scales were independently associated with worse CES-D scores (P = 0.01-0.06) Conclusion. SSc-GIT involvement is associated with depressed mood. Reflux and constipation scales of UCLA-SCTC GIT 2.0 were independently associated with CES-D. Future studies should assess if treatment of GIT symptoms will improve depressed mood in patients with SSc-GIT.
