Is there a relationship between Internet dependence and eating disorders? A comparison study of Internet dependents and non-Internet dependents.

OBJECTIVES

Coeliac disease (CD) is a chronic autoimmune disease of the small intestine caused by the ingestion of gluten, in which musculoskeletal manifestations may occur. Aim of this study was to evaluate the prevalence and severity of joint involvement in paediatric patients with CD using musculoskeletal ultrasound (US).

METHODS

Consecutive paediatric CD patients were enrolled and underwent US evaluations at level of knees, hips and ankles. The presence of joint effusion (JE), synovial hypertrophy, power Doppler signal and structural damage lesions (bone irregularities and erosions) was registered. Inflammatory abnormalities were scored on a semi-quantitative scale (0-3), and structural damage lesions on a dichotomous scale (0-1).

RESULTS

Seventy-four CD children (mean age: 7.6 years; range: 1-14.2; M/F 24/50) were enrolled. Thirty-eight were on a gluten-containing diet (GCD) and 36 on a gluten-free diet (GFD). US showed the presence of abnormalities in 23 patients overall (31.1%); JE was the most frequently observed change (23/23). US abnormalities were observed in 19 patients (50.0%) of GCD group and in 4 of GFD group (11.1%, p=0.007). Interestingly, 12/23 (52.2%) patients with US-detected changes were asymptomatic.

CONCLUSIONS

This is the first US study demonstrating joint involvement in children with CD. JE, the most frequent manifestation, was present also in asymptomatic patients and was reduced in those on GFD. These findings may indicate that, also at joint level, an inflammatory response represented by the appearance of JE may be induced by exposure to gluten.
