Abstract
Background
Data on prevalence of extraintestinal manifestations (EIMs) in inflammatory bowel disease (IBD) range from 6% up to 47%. Recently, several red flags and questionnaires have been proposed for early diagnosis of articular manifestations. Our aim was to analyse the prevalence of EIMs in a single-centre prospective cohort, using a comprehensive questionnaire developed by our group to detect all EIMs (EMAIL questionnaire).
Methods
Patients with IBD attending our Clinic from November 2017 to January 2019 were interviewed using a two-part questionnaire, the first part for clinical-demographic data and the second part for EIMs. Patients positive to screening were referred for multidisciplinary approach.
Results
Two hundred and six IBD patients were interviewed, 114 (55.3%) Crohn’s disease (CD) and 92 (44.7%) ulcerative colitis (UC), 52.4% male, mean age 46.7 years (SD ± 15,2). Sixty (53%) CD patients and 48 (52%) UC patients, in total 108, had history of at least one EIM. Articular EIMs were found in 49 patients (24%); peripheral arthritis was found in 14% (29/206), axial arthritis in 9.7% (20 patients): seven patients (3.4%) had ankylosing spondylitis, 13 (6.3%) sacroiliitis. Cutaneous EIMs were detected in 39 patients (19%), erythema nodosum in 15 patients (7.3%), pyoderma gangrenosum in 9 (4.4%), psoriasis in 15 (7.3%) and folliculitis in 7 (3.4%). Ocular EIMs were observed in 35 patients (17%): uveitis in 7 patients (3.4%), conjunctivitis in 8 (3.9%), optic neuritis in 2, glaucoma in 2 patients, cataract in 13 (6,3%), dry eye in 4 (1.9%), central serous chorioretinopathy in 1. Hepatobiliary EIMs were observed in 31 patients (15%): 26 steatosis (12.6%), 5 (2.4%) primary sclerosing cholangitis. Four (2%) patients had DVT. Articular EIMs were more frequent in CD patients (p = 0.001). Skin manifestations were more frequent in female (p = 0.002) in CD (p = 0,032) and related with IBD activity (<0.001). Hepatobiliary manifestations were more frequent in male (p = 0,017) and in UC (p = 0,044). There was a significant correlation between DVT and IBD activity (p = 0,016).
Conclusion
The questionnaire developed by our group proved to be a sensitive screening tool. Articular and cutaneous EIMs are more frequent in CD, hepatobiliary EIMs are more frequent in UC. A gender difference has been found since cutaneous EIMs are more frequent in females, hepatobiliary more in males. Cutaneous EIMs and DVT are related with IBD activity.
