The Frequency of Primary Sjogren’s Syndrome and Fibromyalgia in Irritable Bowel Syndrome

OBJECTIVE To determine the frequency of sicca complex, Sjogren's Syndrome (SS) and Fibromyalgia (FM) in patients with Irritable Bowel Syndrome (IBS). METHODS Seventy seven IBS patients who fulfilled the Rome-III criteria were included in the study. All patients were assessed for FM according to the American College of Rheumatology (ACR) 2010 criteria. After examination for objective evidence of sicca complex by Schirmer test, TBUT and Ocular Staining Score (OSS), serological tests were performed. And the diagnosis of SS was made according to the American College of Rheumatology (ACR) classification criteria for SS - 2012. RESULTS Thirteen (16.9%) of IBS patients had FM. Dry eye was detected in 20(26.0%), 7(9.1%) and 29(37.7%) patients by OSS, Schirmer test and TBUT, respectively. Of 77 patients with IBS, the diagnosis of SS was established in two patients (2.6%). CONCLUSION The frequency of Sjogren's Syndrome among patients with IBS is relatively higher than the general population. All IBS patients should be questioned for dryness of the mouth and eyes, and if necessary, should be evaluated for SS.
