Abstract
AIM OF THE STUDY: To evaluate the prevalence and the type of liver pathology in children at the time of diagnosis of celiac disease (CD). MATERIAL AND METHODS: Data from newly diagnosed children with CD hospitalized in the university hospital were retrospectively reviewed. Liver pathology was defined as elevated alanine transaminase (ALT) and/or gamma-glutamyl transpeptidase (GGT) serum activity and/or pathological changes of the organ in ultrasound. RESULTS: Liver pathology was detected in 17 of 149 children (11.4%). Ten patients (6.7%) had an elevated ALT serum activity, whereas no child had an elevated GGT activity. Pathological changes of liver in ultrasound (mainly enlargement or steatosis of the organ) were found in 12 patients (8.1%), of whom 5 children (3.4%) had simultaneously elevated ALT serum activity. Children with liver pathology had lower iron (Fe) (p = 0.02) and folic acid (p = 0.01) concentrations compared to the rest of the patients. There were no statistically significant differences between liver pathology existence and age, sex, serum immunoglobulin A anti-tissue transglutaminase type 2 antibodies (IgA anti-TG2), ferritin, vitamin B12, or vitamin D concentrations. Moreover, a positive correlation between IgA anti-TG2 concentration and ALT serum activity was found (p < 0.01, R = 0.29). CONCLUSIONS: Liver pathology is present at diagnosis in a significant proportion of children with CD in the form of hypertransaminasemia and pathological changes of the organ in ultrasound. There is a correlation between IgA anti-TG2 concentration and ALT serum activity.
