Prevalence of functional gastrointestinal disorders in adults with systemic lupus erythematosus.

Abstract

Objective (a) to assess the prevalence of functional gastrointestinal disorders (FGIDs) in female Mexican systemic lupus erythematosus (SLE) patients using the Rome III criteria and (b) to examine the effect of disease duration on FGID prevalence. Methods Female SLE outpatients aged ≥18 years with no organic gastrointestinal disorder were included. Participants were invited to upper gastrointestinal endoscopy screening and a faecal immunochemical test. FGID symptoms were evaluated using the Rome III questionnaire. Results Eighty-six SLE patients with median age of 45 (interquartile range 34-54) years were included. At least one FGID was found in 76.7% (66/88) of patients with SLE. The most prevalent domains of FGID diagnosed were functional oesophageal, gastroduodenal disorders and bowel disorders, of which functional dyspepsia (72.7%), functional heartburn (68.1%) and bloating (63.8%) were the most frequent. Fifty-nine per cent of patients had overlapping FGIDs. The most prevalent overlap was the combination of functional dyspepsia and functional heartburn. Patients with longer disease duration had a higher prevalence of FGID than those with shorter disease duration. Conclusions There was a high prevalence of FGIDs in Mexican SLE women with low disease activity. Overlapping FGIDs were frequent. Longer disease duration may be associated with FGIDs in SLE patients.
