title: Thymalfasin (thymosin-alpha 1) therapy in patients with chronic hepatitis B.
abstract: Chronic hepatitis B virus (HBV) infection is a serious clinical problem because of its world-wide distribution and potential adverse sequelae. Globally, there are approximately 350 million people infected with chronic HBV, 75% of whom live in the Asia-Pacific region. Interferon-alfa and direct anti-viral agents such as lamivudine and adefovir are effective in the therapy of chronic HBV infection but the efficacy is far from satisfactory, particularly in perinatally infected patients, patients with lower ALT levels and those with HBeAg-negative chronic hepatitis B. Thymalfasin (thymosin-alphal) is an immunoregulatory agent able to enhance Thl response. It has been shown to trigger maturational events in lymphocytes, to augment T-cell function, and to promote reconstitution of immune defects. Studies are underway in both monotherapy and combination therapy with thymalfasin and interferon and results are promising.
