[Liver abnormalities in adult celiac disease. Clinicopathologic characterization and outcome after therapy].
OBJECTIVE
The clinical manifestations of adult celiac disease are highly varied and may include liver disease. The present study aimed to characterize liver abnormalities and outcome after a gluten-free diet in patients with celiac disease diagnosed in a hepatology clinic.


METHODS
The clinical records of patients diagnosed with celiac disease during a 7-year period were reviewed.


RESULTS
Of 1916 patients attending a first consultation at the clinic, 10 were finally diagnosed with celiac disease. All patients had been referred for evaluation of persistent elevation of liver enzyme levels. All patients were young (mean age 30 years, range 21-39 years) and there were more women than men (eight women, 80%). Six patients (60%) had additional manifestations attributable to undiagnosed celiac disease, sometimes since childhood. In all patients, elevation of liver enzyme levels was moderate and overall liver function was preserved. Liver biopsy was performed in five patients and all showed chronic periportal infiltrate. Immunohistochemical studies revealed that the infiltrate was mainly composed of CD8-positive T lymphocytes. In all patients, a gluten-free diet was followed by normalization of liver enzyme levels.


CONCLUSIONS
Although celiac disease is not highly frequent, it should be considered in the differential diagnosis of patients with persistent abnormalities of liver markers. The most conspicuous histopathological change is periportal T-cell infiltrate. Liver abnormalities in celiac disease are generally mild and improve after a gluten-free diet.
