OBJECTIVES: The aim of the present study was to determine the proportion of pediatric patients with celiac disease (CD) who had transaminases obtained at diagnosis and to determine the proportion with hypertransaminasemia.
METHODS: Data from newly diagnosed patients with CD at Nationwide Children's Hospital from February 2007 to March 2014 were retrospectively reviewed. Alanine transaminase (ALT) and aspartate transaminase (AST) values at diagnosis and after initiation of a gluten-free diet (GFD) were assessed.
RESULTS: Of 388 patients (mean age 10.1 ± 4.4 years, 235 girls), 185 (47.7%) had transaminases obtained at the time of diagnosis. Twenty-eight of one hundred eighty-five (15.1%) had an elevated ALT and/or AST level with an average ALT 2.52 × upper limit of normal (ULN) and AST 1.87 × ULN. Those with hypertransaminasemia were younger than those with normal levels (6.31 ± 4.75 vs 11.00 ± 4.28 years, P < 0.0001). Sex, symptoms at diagnosis, and weight, height, and body mass index z scores were not predictive of elevated transaminases. Of the 21 patients with hypertransaminasemia at diagnosis who had repeat laboratory test results after starting the GFD, 15 (71.4%) normalized whereas 6 (28.6%) remained elevated.
CONCLUSIONS: There is variation in practice among pediatric gastroenterologists in the assessment of transaminases in children with CD. Hypertransaminasemia is present at diagnosis in a significant proportion of children with CD although at a lower frequency than previously reported. Younger patients are more likely to have an elevation in transaminases. Abnormal transaminases normalize in the majority of patients within 1 year after initiation of a GFD.
