Objectives: This study aimed to show the relationship between gluten-free diet (GFD) compliance in Celiac Disease (CD) and early atherosclerotic findings in pediatric patients and to test the effectiveness of carotid-intima-media-thickness (cIMT) to possibly predict long-term compliance to the GFD. Methods: Patients from 6 to 18 years of age with a diagnosis of CD confirmed by endoscopic duodenal biopsy who were followed at our hospital's pediatric gastroenterology outpatient clinic between November 2020 and May 2021 were evaluated in this single-center, prospective study. The study patients were divided into two groups according to GFD compliance. Serologic and biochemical tests were conducted routinely during the follow-up period. cIMT was measured using ultrasound for both groups. Results: A total of 80 patients (GFD-non-compliant: n = 35, GFD-compliant: n = 45) were evaluated. No significant differences were observed between the groups in terms of demographic data and pathology results. The mean cIMT value was 0.44 ± 0.028 mm for the GFD-compliant group and 0.54 ± 0.036 mm for the GFD-non-compliant group, with a statistically significant between-group difference (P <.001). The receiver operating characteristic curve analysis showed an area under the curve of 0.992 (95% confidence interval [CI]: 0.978–1, P <.001) for discrimination of the groups. In addition, a cutoff value of 0.486 mm for cIMT showed 96% (95% CI: 0.83–0.99) sensitivity and 94% (95% CI: 0.79–0.99) specificity for distinguishing GFD-compliant patients from non-GFD-compliant patients. Conclusion: In this study, the relationship between long-term GFD compliance and cIMT was demonstrated in CD. Currently used by some authors for the assessment of preclinical atherosclerosis, cIMT can also be used as a long-term indicator of dietary compliance as well as cardiovascular risk.
