摘要:

目的    了解0~7岁儿童乙型肝炎病毒(HBV)血清学模式及其分布特征。方法 收集2013年1月至12月重庆医科大学附属儿童医院0~7岁就诊儿童HBV血清学标志物检测结果及HBV表面抗原(HBsAg)(+)患儿家族史,对其资料进行回顾性分析。结果 共检出17种血清学模式,各模式在不同年龄组检出率不同。HBsAg总检出率为0.32%,各年龄组HBsAg检出率差异无统计学意义。模式10“HBV表面抗体(抗-HBs)(+)、HBV核心抗体(抗-HBc)(+)”、模式11“抗-HBs(+)、HBV e抗原(HBeAg)(+)、抗-HBc(+)”、模式12“抗-HBs(+)、HBV e抗体(抗-HBe)(+)、 抗-HBc(+)”、 模式16“抗-HBc(+)”及模式17“抗-HBe(+)、 抗-HBc(+)”在0~28 d组、 >28 d至1岁组的检出率均明显高于其余各年龄组(P<0.05)。HBV前S1抗原(PreS1-Ag)(+)见于5种血清学模式,以“HBsAg(+)、HBeAg(+)”模式检出率最高(100%),其次为“HBsAg(+)、HBeAg(+)、抗-HBc(+)”模式(80.77%)。PreS1-Ag在HBeAg(+)组中的检出率为80.72%,明显高于HBeAg(-)组(25.00%),两组检出率比较,差异具有统计学意义(χ2=14.083,P=0.000)。结论 重庆医科大学附属儿童医院0~7岁儿童HBsAg阳性率随年龄增长无明显变化,而HBV血清学模式分布与年龄相关。PreS1-Ag与HBeAg具有相关性,二者联合检测能更好地反映HBV复制情况,具有重要临床价值。

Abstract:

Objective    To investigate the serological patterns of hepatitis B virus and the distribution characteristics among 0-7-year-old children. Methods    The detection results of hepatitis B virus serological markers (HBVM) in 0-7-year-old children and the family history of ‘HBsAg(+)’ children from Children's Hospital of Chongqing Medical University in 2013 were analyzed retrospectively. Results    Seventeen serological patterns of hepatitis B virus were found,and the detection rate of each pattern in different age groups was different. The positive rate of HBsAg was 0.32%,and there were no significant differences in HBsAg positive rate in different age groups. The detection rates of ‘anti-HBs(+) anti-HBc(+)’,‘anti-HBs(+) HBeAg(+) anti-HBc(+)’,‘anti-HBs(+) anti-HBe(+) anti-HBc(+)’,‘anti-HBc(+)’ and ‘anti-HBe(+) anti-HBc(+)’ in 0 to 28 day age group and 1 month to 1-year age group were significantly higher than other age groups (P<0.05). PreS1-Ag was detected in five serological patterns,the highest frequency pattern was ‘HBsAg(+) HBeAg(+)’ (100%), followed by ‘HBsAg(+) HBeAg(+) anti-HBc(+)’. The detection rate of PreS1-Ag in the HBeAg (+) group was 80.77%,which was significantly higher than the HBeAg (-) group (χ2=14.083,P=0.000). Conclusion    There is no significant change in positive rate of HBsAg with the increase of age among 0-7-year-old children in Chongqing,but the distribution of serological patterns is associated with age. There is correlation between PreS1-Ag and HBeAg,and the combined test of the two serological markers can better reflect the HBV replication,which has important clinical value.
