ABSTRACT
Several studies have demonstrated that viral load is a key factor to determine the development of HBV infection and to assess treatment options for the disease. There is a lack of studies analyzing viral load levels in chronic hepatitis B patients in Argentina and the epidemiologic information is limited. The aim of this study was to determine viral load levels and its distribution in patients diagnosed with chronic hepatitis B from geographical areas with high prevalence for HBV in Argentina. Fifty-one per cent of the study population had HBV DNA levels > or = 10(4) copies/ml and a median viral load of 11,910 copies/ml. The viral load was significantly higher in HBeAg seropositive patients compared with those seronegative for HBeAg (P < 0.05). Salta and Entre Ríos provinces showed low viral loads, while Chaco, Misiones and Formosa provinces had a median viral load ranging between 10(4) and 10(5) copies/ ml. This is the first study providing detailed information on viral load in chronic hepatitis B patients from Argentina. Availability of viral load levels in chronic hepatitis B enables evaluation of implementation of actions to analyze follow-up and/or treatment options for preventing disease complications, improving health care and diminishing the potential burden on the health care system.
