We examined whether the hepatitis B virus (HBV) pregenomic RNA (pgRNA) status after nucleos(t)ide (NA) treatment can predict the long‐time prognoses of chronic hepatitis B patients. Patients with chronic hepatitis B (98) who were treatment‐naïve and had begun a 7‐year NA therapy regimen were enrolled in this study. Biochemical indicators and serological markers of HBV infection were performed during therapy. HBV pgRNA was quantified by real‐time quantitative PCR with specific primers. During treatment, HBV DNA undetectable rates increased. The aminotransferase (ALT) normalization (ALT < 50 IU/L) and HBeAg‐negative rates also increased. After 48 weeks’ NA treatment, 48.28% (28/58) of HBV DNA undetectable patients still had HBV pgRNA‐positive. After 7 years of treatment, more HBV pgRNA‐negative patients (n = 35) achieved HBeAg clearance than the patients who were HBV pgRNA‐positive (n = 63) (19/23 vs 19/56, P < .00). HBV pgRNA‐positive patients also had an increased risk of failing to achieve HBeAg clearance (OR = 9.25, 95% CI: 2.75‐31.08). The median time to HBeAg clearance in the HBV pgRNA‐positive patients was longer than that of the HBV pgRNA‐negative patients (152 weeks vs 72 weeks). The HBV pgRNA‐positive patients also required more time to achieve HBV DNA undetectable (124 weeks, 95% CI: 103.33‐144.67 vs 48 weeks, 95% CI: 34.80‐61.20). The HBV pgRNA status after NA treatment can predict the long‐term prognoses of patients with chronic HBV. Patients who remain HBV pgRNA‐positive after 48 weeks of NA treatment have an increased risk of not achieving HBeAg clearance, need more time to achieve HBeAg clearance and undetectable HBV DNA load.
