摘要:
目的 探讨内蒙古自治区蒙古族聚集区丁型肝炎病毒(HDV)感染情况以及分子流行病学特点。 方法 纳入2019年4月—2020年10月在国际蒙医医院就诊的乙型肝炎表面抗原(HBsAg)阳性的患者230例,根据患者情况分为乙型肝炎合并肝硬化组(n=18)和乙型肝炎组(n=212);并以HBsAg定量值250 IU/mL为界限将患者分为HBsAg<250 IU/mL组(n=104)和HBsAg≥250 IU/mL组(n=126)。采用ELISA方法进行HDV抗体的检测,抗体阳性者进一步利用实时定量PCR方法进行HDV RNA检测。并对HDV RNA阳性标本进行分型检测。计数资料两组间比较采用χ2检验。 结果 HDV抗体检测阳性率为16.09%,抗体阳性患者中HDV RNA阳性率为91.89%。乙型肝炎合并肝硬化患者共18例,HDV抗体检测阳性率为44.44%,抗体阳性患者HDV RNA阳性率为100%。HBsAg<250 IU/mL的患者共104例,其中只有3例(2.88%)HDV抗体阳性。而HBsAg≥250 IU/mL的患者共126例,HDV抗体阳性率为26.98%。所有能测出分型的标本的基因分型均为1型。 结论 内蒙古自治区蒙古族聚集区HDV感染率较高,尤其是HBsAg≥250 IU/mL及肝硬化患者。需加强HBsAg阳性患者的丁型肝炎检测,及早诊断和治疗,防止肝炎进一步发展。 Abstract:Objective To investigate the status and molecular epidemiology of hepatitis D virus (HDV) infection in the gathering area of Mongolian population in Inner Mongolia Autonomous Region of China. Methods A total of 230 patients with positive hepatitis B surface antigen (HBsAg) who attended Inner Mongolia International Mongolian Hospital from April 2019 to October 2020 were enrolled, and according to related information, they were divided into hepatitis B+liver cirrhosis group(n=18) and hepatitis B group(n=212). According to HBsAg quantification with a cut-off value of 250 IU/mL, the patients were divided into HBsAg < 250 IU/mL group(n=104) and HBsAg ≥250 IU/mL group(n=126). ELISA was used to detect HDV antibody, and quantitative real-time PCR was used to measure HDV RNA in patients with positive HDV antibody. Genotyping was performed for HDV RNA-positive samples. The chi-square test was used for comparison of categorical data between two groups. Results The positive rate of HDV antibody was 16.09%, and among the patients with positive HDV antibody, the positive rate of HDV RNA was 91.89%. Among the 18 patients with hepatitis B and liver cirrhosis, the positive rate of HDV antibody was 44.44%, and among the patients with positive HDV antibody, the positive rate of HDV RNA was 100%. There were 104 patients with HBsAg < 250 IU/mL, among whom only 3 patients (2.88%) were positive for hepatitis D antibody, and there were 126 patients with HBsAg ≥250 IU/mL, with a positive rate of HDV antibody of 26.98%. Genotype 1 was observed in all the samples that could be genotyped. Conclusion There is a relatively high infection rate of HDV in Inner Mongolia Autonomous Region, especially in patients with HBsAg ≥250 IU/mL or those with liver cirrhosis. It is necessary to strengthen the detection of hepatitis D in HBsAg-positive patients and perform early diagnosis and treatment to prevent the further progression of hepatitis. -
