Effect of gastrointestinal manifestations on quality of life in 87 consecutive patients with systemic sclerosis

Abstract

Objective: To assess the effect of gastrointestinal (GI) manifestation on the quality of life in patients with systemic sclerosis (SSc).

Methods: The University of California, Los Angeles Scleroderma Clinical Trial Consortium Gastrointestinal Tract 2 questionnaire was completed by 87 consecutive patients with SSc attending the scleroderma clinic at a single center. Their clinical features and current therapies were recorded; 100 patients with rheumatologic disorders other than SSc were used as controls. Individual scores were compared between SSc and controls, and between SSc subgroups.

Results: Of 87 patients, 76 (90%) were women. Median age was 55 years and disease duration 105 months. Thirty-three (38%) had diffuse and 54 (62%) had limited SSc. Patients with SSc had a higher score than controls in all domains (p < 0.05). Numbers of patients who responded positively to individual questionnaire components are as follows: any GI symptom 86 (99%), reflux 77 (89%), distension 73 (84%), soilage 19 (22%), diarrhea 44 (51%), constipation 51 (59%), well-being 43 (49%), and social 43 (49%). There was no difference between the scores of patients with diffuse and limited disease subtypes. The use of calcium channel blockers did not significantly increase the constipation score (p = 0.99). Patients who responded positively to the reflux, distension, diarrhea, and constipation domains had lower scores in the well-being and social domains.

Conclusion: GI manifestations, especially fecal incontinence (affecting 22% of patients), have a negative influence on the quality of life of patients with SSc. There was no difference between SSc disease subtypes.
