Host immune factors play essential roles in all phases of the CHB infection. Cytokines may alter infection course, influencing the propensity for and the progression of CHB and thus warrant study. Three clinical groups were studied: 48 healthy individuals (HI), 28 patients with persistent positive anti-HBc serological markers and negative HBsAg over time, who were diagnosed as OBI and 12 patients with active CHB. OBI patients were defined by three independent detections of the hepatitis B virus genome through nested PCR and real-time PCR.
