Abstract

Objective: To understand the current genotype distribution, epidemiological characteristics, and their relationship with pregnancy outcomes in pregnant women with hepatitis C in Nanjing city. Methods: An epidemiological survey method was used to analyze the data of 113 pregnant women with hepatitis C who were successfully genotyped and admitted to Nanjing Second Hospital from January 2018 to December 2023. The comparison of the quantitative data was analyzed by a t-test or rank-sum test between the two groups. The comparison of the enumeration data was analyzed using the χ2 test, adjusted χ2 test, or Fisher's exact probability method between the two groups. Results: A total of six kinds of genotypes (1b, 2a, 3a, 3b, 6a, 6n) were identified in 113 cases. The primary genotype was 1b (accounted for 76.1%), followed by 6, 3, and 2 rare genotypes, while 1 mixed type (type 2 mixed with type 6) and genotypes 4 and 5 were non-identified. The proportion of genotype 1b increased with the extension of the birth cohort, and the difference was statistically significant (χ2=24.35, P<0.001). There was a difference in genotyping proportions with educational and employment background (χ2=14.74, P<0.001; χ2=19.50, P<0.001). The proportion of non-1b types increased in populations with low educational backgrounds and unemployment. The proportion of type 1b was higher in those with a history of blood transfusion and hospitalization during infancy (χ2=5.57, P=0.018; χ2=5.17, P=0.023). The proportion of non-1b type was higher in those with a history of drug abuse (χ2=22.32, P<0.001). Normal pregnancy outcomes had no statistically significant difference between genotype 1b and non-1b groups. However, all pregnant women who experienced adverse infant outcomes had genotype 1b. Conclusion: Pregnant women with hepatitis C in Nanjing city are mainly genotype 1b, with genotype 3b<5%, and there is no significant difference in maternal and infant outcomes among different genotype subtypes. Therefore, no testing of genotype for women of childbearing age. However, the focus should be on the management of pregnancy, health education, and postpartum preparation for direct acting antiviral treatment.

[丙型肝炎孕妇基因分型的现状及其对妊娠结局的影响]。
目的:了解南京市丙型肝炎孕妇基因型分布、流行病学特征及其与妊娠结局的关系。方法:采用流行病学调查方法,对2018年1月至2023年12月南京市第二医院收治的基因分型成功的113例丙型肝炎孕妇资料进行分析。两组间定量资料比较采用t检验或秩和检验。采用χ2检验、校正χ2检验或Fisher精确概率法对两组间计数资料的比较进行分析。结果:113例患者共检出6种基因型(1b、2a、3a、3b、6a、6n)。主要基因型为1b(占76.1%),其次为6、3、2种罕见基因型,1种混合基因型(2型与6型混合)和4、5型未被发现。基因型1b的比例随着出生队列的延长而增加,差异有统计学意义(χ2=24.35, P<0.001)。不同教育、就业背景的人群基因分型比例差异有统计学意义(χ2=14.74, P<0.001;χ2 = 19.50,P < 0.001)。在低教育背景和失业人口中,非1b型人口的比例有所增加。婴儿时期有输血和住院史者1b型比例较高(χ2=5.57, P=0.018;χ2 = 5.17,P = 0.023)。非1b型在有药物滥用史人群中所占比例较高(χ2=22.32, P<0.001)。基因型1b组与非基因型1b组正常妊娠结局无统计学差异。然而,所有经历不良婴儿结局的孕妇都是基因型1b。结论:南京市孕妇丙型肝炎以基因型1b为主,基因型3b居多
