Axial and peripheral arthropathies are among the most prevalent extraintestinal manifestations in patients with Inflammatory Bowel Disease (IBD). This study has been designed to examine rheumatologic indices in patients registered in IBD bank of Golestan University of Medical Sciences (GOUMS).

In this cross-sectional study during September 2017 to December 2018, 101 patients with IBD (UC=81, Crohn’s disease=18, and 2 were undifferentiated IBD; male to female ratio: 44 to 57; mean (SD) age, 38± 11 years) recruited from the IBD registry in Golestan Research Center of Gastroentrology and Hepatology, Golestan University of Medical Sciences, Golestan, Gorgan, Iran. The study has been approved by the Ethical committee of GOUMS. After taking the informed consent, all patients have been interviewed by a trained physician and a questionnaire has been completed. The rheumatologist examined the symptoms and signs of peripheral arthritis, sacroiliitis, enthesitis and inflammatory low back pain. Schober’s test was done in all patients (positive: lower than 5 cm). After entering data into the SPSS-16 software, analysis was done using X2 and non-parametric tests.

Among 101 patients with IBD, 5 had positive Schober’s test (% 5), 5 (5%) inflammatory low back pain, and 6 (6%) enthesopathy. Inflammatory low back pain and positive Schober's test was seen in 3 males and 2 females, 3 patients with UC and 1 with CD (significant differences). Enthesopathy was seen in 3 males and 3 females, and in 3 UC and 2 CD (significant differences).

Low frequency of rheumatologic presentations was seen in the studied patients with IBD.
