Inactive HBV Carrier State
This group of patients has positive HBsAg and a low level of HBV load (i.e. < 1 x 105 copies/ml). Clinically, these patients have normal transaminases (i.e. ALT and AST) and no symptoms related to HBV infection. Histologically, most patients do not have significant hepatitis.
Three different outcomes have been described in inactive HBV carriers. While 70-80% remain in inactive HBV carriers indefinitely, 10-20% may develop HBeAg-positive CHB presented with a high level of HBV DNA, elevated transaminases and hepatic inflammation. Anti-HBe-positive hepatitis may occur in inactive HBV carriers, but the frequency of this transition remains unknown. Approximately 0.5% of the inactive HBV carriers spontaneously lose HBsAg annually. It should be noted that all HBV carriers are at increased risk of developing HCC.

In the meantime, it is reasonable for clinicians who care for persons with chronic HBV infection to follow all HBsAg carriers at regular intervals to determine whether liver disease is occurring and to prepare to treat patients manifesting progressive liverМеждувременно е разумно лекарите, които се грижат за хората с хроничен хепатит В, да проследяват всички носители на HBsAg през определени интервали, за да определят дали имат чернодробно заболяване и да бъдат готови за лечение с антивирусна терапия при очевидно прогресивно увреждане на черния дроб.
