Celiac disease clinical presentation is constantly changing. We set to determine the prevalence of elevated transaminases in newly diagnosed celiac patients and to evaluate this sub-group of patients for associated clinical and laboratory findings and assess their natural course of disease following therapeutic diet initiation. We conducted a prospective-observational study of all newly diagnosed pediatric celiac patients, between August 2016 and April 2018, in a pediatric gastroenterology clinic. Clinical data, anthropometrics, and blood test results were recorded at diagnosis and at 3, 6, and 12 months, respectively, of follow-up. We compared patients with normal and elevated transaminases at diagnosis. ALT threshold was set at 24 U/l. Of 125 newly diagnosed celiac patients, 31 (24.8%) had elevated ALT at diagnosis; two (1.6%) with over 3 × ULN. Patients with elevated ALT at diagnosis were significantly younger (mean age 5.5 (SD 3.4) vs. 7.3 (SD 3.7) years, p < 0.01) and more commonly presented with diarrhea (32.3% vs. 14.9%, p = 0.03). Eighty percent of patients with elevated ALT levels normalized their ALT within 3 months and all within 1 year. Following gluten-free diet initiation, patients with elevated ALT had similar clinical course, growth, serology normalization rate, and laboratory results, compared to patients with normal ALT over a 1-year follow-up. A single patient was simultaneously co-diagnosed with celiac disease and autoimmune hepatitis. Conclusion: Clinically significant ALT abnormalities are rare among newly diagnosed pediatric celiac patients. Significant elevations failing to normalize on a gluten-free diet should raise concern of a concomitant primary liver disease and warrant further investigations.What is Known:• Elevated liver enzymes may be an extra-intestinal manifestation of celiac disease.• Reported prevalences of ALT elevations among children with a new diagnosis of celiac disease ranges between 5 and 40%.What is New:• ALT elevations are present in 25% of children with a new diagnosis of celiac disease.• Significant elevations (>3 × ULN) are rare (1.6%).• Elevated liver enzymes are associated with earlier age at diagnosis.• The natural history of patients with elevated liver enzymes at diagnosis is comparable to those without.
