| 目的探究妊娠合并慢性乙型肝炎病人血清乙型肝炎病毒( HBV)前基因组 RNA(HBV pgRNA)、前 S1抗原( PreS1 Ag)水平变化及与妊娠期肝内胆汁淤积症( ICP)发生的相关性。方法选取 2017年 6月至 2020年 6月在雅安市人民医院进行孕期检查的慢性乙型肝炎孕妇 279例作为研究对象，根据入组病人是否患有 ICP分为合并 ICP组 43例、未合并 ICP组 236例。比较两组病人血清中 HBV pgRNA、PreS1 Ag水平，并分析两组血清 HBV pgRNA、PreS1 Ag表达与 HBV DNA表达水平相关性；比较两组病人妊娠结局，并分析合并 ICP组病人血清 HBV pgRNA表达水平及 PreS1 Ag阳性表达率与妊娠结局的关系。受试者操作特征( ROC)曲线分析血清 HBV pgRNA、PreS1 Ag光密度［D(λ)］值诊断慢性乙型肝炎孕妇合并 ICP的效能。结果合并 ICP组慢性乙型肝炎病人血清 HBV表面抗原( HbsAg)水平［( 3.71±0.92)log IU/mL］、 HBV e抗原(HbeAg)阳性率［65.12%(28/43)］、 HBV DNA含量［( 8.03±1.69)log copies/mL］、天冬氨酸转氨酶( AST)［( 79.68±15.73)U/L］、丙氨酸转氨酶( ALT)［( 72.08±16.95)U/L］、 PreS1 Ag阳性表达率［88.37%(38/43)］、 PreS1 Ag D(λ)值水平( 1.24±0.25)及 HBV pgRNA表达水平［( 5.17±1.25)log copies/mL］明显高于未合并 ICP组［( 2.26±0.74)log IU/mL、24.15%(57/236)、(5.19±1.07)log copies/mL、(23.01±12.47)U/L、(21.76±10.51)U/L、67.80%(160/236)、(0.92±0.23)、(3.02±0.98)log copies/mL］(P<0.05)。血清HBV pgRNA诊断慢性乙型肝炎孕妇合并 ICP的曲线下面积( AUC)为 0.89，灵敏度为 81.40%，特异度为80.50%。PreS1 Ag D(λ)值诊断慢性乙型肝炎孕妇合并 ICP的 AUC为 0.83，灵敏度为 76.70%，特异度为 79.20%。二者联合诊断的 AUC为 0.91，灵敏度为 93.00%，特异度为 78.40%。合并 ICP组、未合并 ICP组血清 PreS1 Ag阳性的慢性乙型肝炎病人血清 HBV DNA、HBV pgRNA表达水平均明显高于 PreS1 Ag阴性表达病人( P<0.05)。合并 ICP组、未合并 ICP组血清HBV pgRNA、PreS1 Ag D(λ)值均与 HBV DNA表达水平呈正相关( P<0.05)。合并 ICP组产后出血、早产的发生率明显高于未合并 ICP组( P<0.05)。发生不良妊娠结局的慢性乙型肝炎合并 ICP病人血清 PreS1 Ag阳性表达率、 PreS1 Ag D(λ)值、 HBV pgRNA表达水平均明显高于未发生不良妊娠结局病人( P<0.05)。结论合并 ICP的慢性乙型肝炎病人血清 HBV pgRNA表达水平、 PreS1 Ag阳性表达率及 D(λ)值水平均明显升高，对 ICP有一定诊断价值，且两者水平变化均与 HBV DNA含量有关，并可能预示病人不良妊娠结局的发生。 |

| Objective To investigate the changes of serum HBV pregenomic RNA (HBV pgRNA) and pre-S1 antigen (PreS1 Ag) lev?els in pregnant women with chronic hepatitis B and their correlation with intrahepatic cholestasis of pregnancy (ICP).Methods A total of 279 pregnant women with chronic hepatitis B who underwent pregnancy examination in Ya'an People's Hospital from June 2017 toJune 2020 were selected as the research objects. According to whether the patients had ICP, they were assinged into ICP group (n=43) and non-ICP group (n=236). The levels of serum HBV pgRNA and PreS1 Ag were compared between the two groups, and the correla?tion between the expressions of HBV pgRNA and PreS1 Ag and the expression of HBV DNA was analyzed. The pregnancy outcomeswere compared between the two groups, and the relationship between serum HBV pgRNA level, PreS1 Ag positive expression rate andpregnancy outcome in ICP group was analyzed. Receiver operating characteristic (ROC) curve analysis was made of serum HBVpgRNA, PreS1 Ag D(λ) value in the diagnosis of chronic hepatitis B pregnant women complicated with ICP.Results The level of se? rum HBV surface antigen (HBsAg) [(3.71±0.92) log IU/mL], positive rate of HBV e antigen (HBeAg) [65.12% (28/43) ], content of HBVDNA [(8.03±1.69) log copies/mL], aspartate aminotransferase (AST) [(79.68±15.73) U/L], alanine aminotransferase (ALT) [(72.08±16.95) U/L], positive expression rate of PreS1 Ag [88.37% (38/43)], PreS1 Ag D(λ) value level (1.24±0.25) and expression level of HBVpgRNA [(5.17±1.25) log copies/mL] in the ICP group were significantly higher than those in the non-ICP group [(2.26±0.74) log IU/mL,24.15% (57/236), (5.19±1.07) log copies/mL, (23.01±12.47) U/L, (21.76±10.51) U/L, 67.80% (160/236), (0.92±0.23), (3.02±0.98) logcopies/mL] (P<0.05). The area under the curve (AUC) of serum HBV pgRNA for the diagnosis of ICP in pregnant women with chronichepatitis B was 0.89, the sensitivity was 81.40%, and the specificity was 80.50%. The AUC of PreS1 Ag D(λ) value in the diagnosis ofchronic hepatitis B pregnant women complicated with ICP was 0.83, the sensitivity was 76.70%, and the specificity was 79.20%. TheAUC of the combined diagnosis was 0.912, the sensitivity was 93.00%, and the specificity was 78.40%. The levels of serum HBV DNAand HBV pgRNA in patients with positive serum PreS1 Ag in ICP group and non-ICP group were significantly higher than those in pa? tients with negative PreS1 Ag (P<0.05). The serum HBV pgRNA and PreS1 Ag D(λ) value in the ICP group and the non-ICP group were positively correlated with the expression level of HBV DNA (P<0.05). The incidences of postpartum hemorrhage and premature birth inthe ICP group were significantly higher than those in the non-ICP group (P<0.05). The positive expression rate of serum PreS1 Ag,PreS1 Ag D(λ) value and the expression level of HBV pgRNA in patients with adverse pregnancy outcomes were significantly higherthan those in patients without adverse pregnancy outcomes (P<0.05).Conclusion The serum HBV pgRNA expression level, the posi?tive expression rate of PreS1 Ag and the D(λ) value of chronic hepatitis B pregnant women complicated with ICP are significantly in?creased, which have a certain diagnostic value for ICP, and the changes of the two levels are related to the content of HBV DNA, andmay indicate poor pregnancy outcomes. |
