<p><b>OBJECTIVE</b>To investigate the short-term spontaneous fluctuation of viral load in patients with chronic hepatitis B (CHB) and explore the related factors in treatment naive CHB patients during immune clearance phase.</p><p><b>METHODS</b>A total of 123 treatment naive HBeAg-positive CHB patients with ALT>2 × ULN were enrolled in this study. Paired serum samples were obtained at the first and second visits with an interval of less than 4 weeks. The levels of quantitative HBV DNA (Roche COBAS), quantitative HBsAg, ALT and AST were analyzed. Liver biopsy specimen were collected within 4 weeks and evaluated using Knodell and Ishak histological scoring system.</p><p><b>RESULTS</b>Of the 123 patients, 93 (75.6%) and 30 (24.4%) had HBV DNA fluctuation ≤ 0.5 Log IU/ml and >0.5 Log IU/ml, respectively. Binary logistic multivariate regression analysis identified Knodell necroinflammation score and HBV DNA level as the factors related to HBV DNA fluctuation. Patients with Knodell necorinflammation score ≥ 10 or HBV DNA<7 Log IU/ml had significantly higher rates of HBV DNA fluctuation>0.5 Log IU/ml (50.0% vs 18.3%, P=0.042; 42.9% vs 20.6%, P=0.030).</p><p><b>CONCLUSION</b>Treatment naive CHB patients in immune clearance phase show short-term spontaneous fluctuation of HBV DNA, and nearly 25% of the patients have HBV DNA fluctuation >0.5 Log IU/ml. Such fluctuation is related to liver inflammation and quantity of HBV DNA.</p>
