The distinction between chronic HBeAg-negative hepatitis (CHB) and chronic HBeAg-negative infection (CIB) can be challenging and important for providing advice on prognosis, as well as determining need for treatment. The aim of the present study was to evaluate pgRNA levels in treatment-naïve HBeAg-negative chronic HBV-infected patients. In addition, pgRNA levels were compared to traditional markers in order to assess their clinical utility. A retrospective study was carried out, including 85 cases of CHBs and 74 CIBs. Globally, when the virological markers (pgRNA, qHBsAg, and HBV DNA) were analyzed, significant differences were found between the CHB and CIB groups (P<0.001). Overall, positive correlations were demonstrated, as follows: between pgRNA levels and qHBsAg (Spearman r=0.30, P<0.001), between pgRNA and HBV DNA (Spearman r=0.73, P<0.001), and between pgRNA and ALT (Spearman r=0.67, P<0.001). Out of the 85 CHB patients, 82 (96.5%) agreed to start treatment. At baseline, 38/82 patients, as well as the 3 untreated CHB patients, had undetectable pgRNA levels. The 74 CIB carriers also had undetectable pgRNA levels. During the follow-up period, no patients experienced viral reactivation or progression of liver disease. These results suggest that the addition of plasmatic HBV-pgRNA levels to the traditional diagnostic flowchart of HBeAg-negative patients may improve the correct identification of cases at risk, especially patients with occasional increases in HBV viremia.

Abstract

The distinction between chronic HBeAg-negative hepatitis (CHB) and chronic HBeAg-negative infection (CIB) can be challenging and important for providing advice on prognosis, as well as determining need for treatment. The aim of the present study was to evaluate pgRNA levels in treatment-naïve HBeAg-negative chronic HBV-infected patients. In addition, pgRNA levels were compared to traditional markers in order to assess their clinical utility. A retrospective study was carried out, including 85 cases of CHBs and 74 CIBs. Globally, when the virological markers (pgRNA, qHBsAg, and HBV DNA) were analyzed, significant differences were found between the CHB and CIB groups (P<0.001). Overall, positive correlations were demonstrated, as follows: between pgRNA levels and qHBsAg (Spearman r=0.30, P<0.001), between pgRNA and HBV DNA (Spearman r=0.73, P<0.001), and between pgRNA and ALT (Spearman r=0.67, P<0.001). Out of the 85 CHB patients, 82 (96.5%) agreed to start treatment. At baseline, 38/82 patients, as well as the 3 untreated CHB patients, had undetectable pgRNA levels. The 74 CIB carriers also had undetectable pgRNA levels. During the follow-up period, no patients experienced viral reactivation or progression of liver disease. These results suggest that the addition of plasmatic HBV-pgRNA levels to the traditional diagnostic flowchart of HBeAg-negative patients may improve the correct identification of cases at risk, especially patients with occasional increases in HBV viremia.
