Brucellosis-associated hepatitis

Brucellosis is a zoonotic infection that can affect almost every organ. A mild elevation of aminotransferase levels is usually observed in liver involvement. However, the development of clinical hepatitis is rare. In this study, we aimed to present the hospitalized cases with brucellosis hepatitis in our clinic in a 13-year period.

A hundred and three patients with significant hepatobiliary involvement, diagnosed by microbiological analysis, were included in the study. For the presence of hepatitis, it was required that the aminotransferases must be ≥ 5 times more than the upper limit and/or the total bilirubin level must be ≥ 2 mg/dl and/or the local hepatic lesion must be demonstrated.

Of the cases, 35.9%, 17.5%, and 46.6% had clinical hepatitis, cholestatic hepatitis, and both clinical and cholestatic hepatitis, respectively. The most frequent symptom was fever (85.4%) while the most preferred treatment options were combinations containing aminoglycosides. It was observed that the mean time-interval to decrease to normal values of ALT, AST, and bilirubin values was 15.2 ± 7.8 days while the patients having their treatment regimens. In our study, which focused on liver involvement, it was found that a chronic liver disease did not develop in any of the cases.

Our study showed that, even in the presence of hepatitis, clinical response and laboratory improvement were high with appropriate treatment. It was observed that the improvement in aminotransferases and total bilirubin values delayed in the cases with blood culture positivity, secondary organ involvement, and alanine aminotransferase/aspartate aminotransferase > 1.
