Cardiac Functions Assessment in Children with Celiac Disease and its Correlation with the Degree of Mucosal Injury: Doppler Tissue Imaging Study

BACKGROUND/AIMS: Celiac disease (CD)-associated cardiologic disorders is a growing concern. However, data regarding cardiac affection in children with CD are few. This study aimed at assessing the subclinical impact of CD on the global myocardial performance in Saudi children with CD using Doppler tissue imaging (DTI). PATIENTS AND METHODS: Conventional two-dimensional echocardiography was performed among 20 Saudi children with CDas well as 20 age and sex-matched healthy controls. DTI were used to determine right ventricular (RV) and left ventricular (LV) Tei indexes. These findings were correlated with the Modified Marsh Classification of the histologic findings in CD. RESULTS: LV and RV Tei indexes were significantly higher in children with CD than the control group (mean ± standard deviation: 0.47 ± 0.05 vs. 0.31 ± 0.18; P < 0.0005 and 0.51 ± 0.04 vs. 0.32 ± 0.05; P < 0.0001, respectively). RV Tei index was found to be positively correlated with the Modified Marsh Classification of CD (r = 0.7753, P < 0.0001). LV Tei index tended to be more affected in patients with more severe histologic findings, however, such relation did not reach statistical significance (r = 0.2479, P = 0.292). Fractional shortening did not correlate with the Modified Marsh Classification of histologic findings in CD patients (r= −0.11, P = 0.641). CONCLUSIONS: Subclinical myocardial dysfunction of both ventricles occurs in children with CD. The DTI method appears to be more sensitive than conventional two-dimensional echocardiography in the early detection of myocardial dysfunction in children with CD.
