摘要 目的:探讨慢性乙型肝炎(CHB)、乙型肝炎肝硬化(HBV-LC)患者HBsAg定量和HBVDNA定量的变化及两者的相关性。方法采集46例CHB轻中度患者(CHB-LM组),24例CHB重度患者(CHB-S组)和28例HBV-LC患者入院时及51例患者经核苷(酸)类似物(NA)抗病毒治疗4.08±3.06月时的血清标本;采用化学发光法定量检测HBsAg水平,荧光PCR定量检测HBVDNA载量。多组比较采用Kruskal-Wallis,两组间比较采用Mann-Whitney U检验,治疗前后比较采用Wilcoxon检测,相关性分析采用Spearman检验。结果 HBsAg和HBVDNA定量在CHB-LM组、CHB-S组和HBV-LC组中逐渐下降(χ2=12.537和8.381,P=0.002和0.015);CHB-LM组和CHB-S组HBsAg和HBV DNA定量值均高于HBV-LC组(P0.05)。HBeAg阳性患者HBsAg和HBVDNA定量在CHB-LM组、CHB-S组和HBV-LC组中呈下降趋势(χ2=6.146,P=0.046和1.009,P〉0.05);CHB-LM组HBsAg定量高于HBV-LC组(Z=-2.247,P=0.025)。HBeAg阴性患者HBsAg和HBVDNA定量在CHB-LM组、CHB-S组和HBV-LC组中逐渐下降(χ2=7.196和14.658,P〈0.05);CHB-LM组和CHB-S组HBsAg和HBV DNA定量均高于HBV-LC组(P〈0.01)。HBsAg与HBVDNA定量水平在CHB-LM组(r=0.389,P=0.009)、HBV-LC组(r=0.431,P=0.022)中均呈正相关性;而在CHB-S组中无相关性(r=0.348,P=0.104)。与NA抗病毒治疗前相比,51例患者治疗后HBsAg水平略有下降(Z=-1.050,P=0.294),而HBVDNA水平明显下降(Z=-5.415,P〈0.001);治疗后HBsAg定量与HBVDNA定量无统计学相关性(r=0.241,P=0.111);且两者治疗前后的差值也无统计学相关性(r=0.257,P=0.085)。结论 HBsAg和HBVDNA定量在CHB-LM、CHB-S和HBV-LC患者中逐渐降低,按照HBeAg阳性和阴性分组后,这种趋势依然存在;HBsAg和HBVDNA之间呈正相关,但并非绝对平行。 Objective To explore the changes in HBsAg titer and HBV DNA load and their correlation in patients with chronic hepatitis B (CHB) and HBV-related liver cirrhosis (HBV-LC). Methods Forty-six patients with mild to moderate CHB (CHB-LM), 24 patients with severe CHB (CHB-S), and 28 patients with HBV-LC at admission, and 51 patients with HBV-LC at 4.08± 3.06 months during antiviral treatment were tested for serum HBsAg titer and HBV DNA load using Abbott chemiluminescence and fluorescence quantitative PCR, respectively. Results The serum HBsAg titer and HBV DNA load gradually decreased with increased disease severity (from CHB-LM, CHB-S to HBV-LC;χ2=12.537 and 8.381, respectively, P0.05). Among HBeAg-positive patients, HBsAg titer and HBV DNA load tended to decrease with increased disease severity (from CHB-LM, CHB-S to HBV-LC;χ2=6.146, P=0.046 andχ2=1.017, P〉0.05;respectively), and CHB-LM group had significantly higher HBsAg titer than HBV-LC group (Z=-2.247, P=0.025). Among the HBeAg-negative patients, serum HBsAg and HBV DNA load gradually declined with the disease severity (χ2=8.660 and 13.581, respectively, P〈0.05), and were obviously higher in CHB-LM and CHB-S groups than in HBV-LC group (P〈0.05). Positive correlations were found between serum HBsAg and HBV DNA levels in CHB-LM (r=0.389, P=0.009) and HBV-LC groups (r=0.431, P=0.022), but not in CHB-S group (r=0.348, P=0.104). After antiviral therapy, the serum HBsAg titer was slightly decreased (Z=-1.050, P=0.294) while HBV DNA load markedly reduced (Z=-5.415, P〈0.001), showing no correlation between them (r=0.241, P=0.111) or between the measurements before and after treatment (r=0.257, P=0.085). Conclusion Serum HBsAg titer and HBV DNA load decreases progressively from CHB-LM to CHB-S and HBV-LC in both HBeAg- positive and-negative patients. The serum HBsAg titer is positively correlated with HBV DNA load, but their levels are not consistently parallel.
