Abstract | OBJECTIVE: METHODS: RESULTS: A total of 266 cases were documented using 3 serologic markers for HBV infection: HBV surface antigen ( HBsAg), HBV surface antibody (HBsAb), and HBV core IgG Ab (HBcAb). Of these, 8 cases had chronic hepatitis B ( HBsAg+), 170 cases were HBcAb-negative, and 88 cases were identified as having potential HBV occult infections represented by HBsAg-negative and HBcAb-positive, irrespective of the status of the HBsAb. The frequency of clinically significant (> 2 times normal value) and persistent increase (> 2 consecutive tests) of aminotransferase levels was significantly higher in the group with a potential HBV occult infection compared to the HBcAb-negative group. In the multiple logistic regression analysis controlling for various potential confounding factors such as prophylactic anti- tuberculosis medication, methotrexate, nonsteroidal antiinflammatory drugs, and the type of anti- TNF-alpha therapy, only potential HBV occult infection was a significant risk factor for abnormal liver function test (LFT). CONCLUSION: All rheumatic patients who plan to take anti- TNF-alpha treatment should undergo a test for HBV serology, including HBcAb, and have a close followup with an LFT test during therapy. Further prospective studies for hepatitis B viral load using HBV-polymerase chain reaction in patients who are HbcAb positive are needed to identify whether the abnormal LFT comes from the reactivation of occult HBV infection.
