Abstract: Background: Spontaneous acute exacerbation (AE) of chronic hepatitis B (CHB) is often detrimental but sometimes leads to sustained immune control and disease remission. The efficacy and safety of nucleos(t)ide analogues (NAs) in patients with spontaneous AE of CHB remains unclear. Methods: We performed a systematic review and meta-analysis of NAs in patients with spontaneous AE of CHB. We calculated pooled effects of NAs in these patients of each study and conducted quantitative meta-analysis, displaying results using Forest plots. Results: 15 studies were included and substantial heterogeneity was noted in the inclusion/exclusion criteria and controls. Pooled data showed no benefit of lamivudine (LAM) vs. untreated controls for transplant-free survival in patients with spontaneous AE of CHB (OR = 0.98 (95% CI, 0.50–1.92; P = 0.956)), hepatic decompensation (OR = 0.94 (95% CI, 0.47–1.88; P = 0.862)) and liver failure owing to AE (OR = 2.30 (95% CI, 0.35–15.37; P = 0.387)) at 3 months. Entecavir achieved even higher short-term mortality than LAM. NAs led to rates of ALT normalization, undetectable HBV DNA, HBeAg loss, HBeAg seroconversion and drug resistance at 1 year in 88%, 61%, 46%, 35% and 5%. Pooled data also showed benefit favoring LAM vs. untreated controls for ALT normalization (OR = 1.98 (95% CI, 1.03–3.80; P = 0.039)) and undetectable HBV DNA (OR = 38.50 (95% CI, 7.68–192.99; P
