Adult celiac disease and hypertransaminasemia.

OBJECTIVE
to determine the incidence of hypertransaminasemia in adult patients with celiac disease with or without relevant chronic liver disease, and to evaluate the response after a gluten-free diet.


PATIENTS AND METHODS
retrospective study of 20 cases of adult celiac disease (> 14 years old at diagnosis). Patients were included in the study if they fulfilled the revised EPSGAN criteria. If laboratory tests of liver function revealed alterations, hepatitis B and C viral serology, thyroid hormones, and use of alcohol and drugs were investigated, and liver ultrasound scans were done. Liver biopsy and endoscopic retrograde cholangiopancreatography were done only in patients for whom these studies were considered necessary.


RESULTS
ten patients had hypertransaminasemia (50%), ascribed to benzodiazepine use in 1 patient, chronic HCV hepatitis in 1, and celiac disease in 8. In all of these last patients except 1 (benzodiazepine use), laboratory values returned to normal after 4-10 months on a gluten-free diet.


CONCLUSIONS
celiac disease was frequently associated with hypertransaminasemia. In most patients transaminase levels returned to normal within 1 year after dietary gluten intake was restricted. If alterations in laboratory values persist, other causes that may be related (e.g., autoimmunity or tumors) or unrelated to celiac disease (e.g., virus) must be ruled out.
