Prevalence of celiac disease in children with joint hypermobility.

Introduction: Generalized joint hypermobility is a clinical feature that is associated with excessive joint laxity, which can occur alone or with various inherited disorders. The term of benign joint hypermobility or joint hypermobility is used when the presence of musculoskeletal symptoms in subjects with generalized joint hypermobility in the absence of demonstrable systemic rheumatic diseases. In recent studies, it was shown that there is a strong relationship between structural and functional gastrointestinal disorders and joint hypermobility. We aimed to analyze the prevalence of celiac disease in a group patient with joint hypermobility.

Patients and methods: The study included the 2 groups of children (i) Group 1; patients with joint hypermobility that were followed in pediatric rheumatology outpatient clinic (n=131). (ii) Group 2; healthy children without known chronic diseases (n=995). Demographic features, clinical findings, accompanying symptoms and anthropometric measurements of all patients were recorded. All cases were screened for celiac disease by serological marker and histopathological examinations if serological marker was positive.

Results: There was no difference between two groups for age, gender, presence of malnutrition and accompanying symptoms (p>0.05). Serology positivity of anti-tissue transglutaminase IgA >20 RU/ml was found in seven patients with joint hypermobility. After histopathological examinations, asymptomatic celiac disease was detected in one (n=1, 0.9%) and potential celiac disease in six patients (n=6, 5.3%). There were six (0.6%) patients with positive serology in the control group. Celiac serology positivity and potential celiac disease were higher in patients with joint hypermobility (6.2%, vs. 0.6%, OR: 10.9, 95% CI: 3.6-33, p < 0.001 and 5.3%, vs. 0.4%, OR: 13.9, 95% CI: 3.6-50, p < 0.001, respectively), but no significant difference was found on the prevalence of asymptomatic celiac disease (0.9%, vs. 0.2%, OR: 4.4, p=0.22).

Conclusion: Our study shows the increased prevalence of potential celiac disease in patients with joint hypermobility. Serological screening of celiac disease is recommended for to rule out organic problems in the presence gastrointestinal symptoms in patients with BJH.
