Abstract:
【Objective】 To analyze the serological markers and RNA prevalence of HEV infection in Chinese voluntary blood donors in different regions of China, so as to provide basis for the necessity of HEV screening and the formulation of screening strategies for voluntary blood donors. 【Methods】 Databases such as CNKI, Wanfang medicine and PubMed were searched for eligible literature, and the literature data meeting the inclusion criteria were extracted for meta-analysis using R4.1.3 software. 【Results】 A total of 26 studies were included, involving 97 928, 117 831 and 82 673 cases, respectively, for anti-HEV IgG, anti-HEV IgM and HEV RNA. The pooled estimated prevalence of anti-HEV IgG, anti-HEV IgM and HEV RNA among Chinese voluntary blood donors was 23.0% [95% CI (18%, 29%)] vs 1.13% [95% CI (0.94%, 1.36%)] vs 0.028%[95%CI(0.006%, 0.059%)], and there were significant differences among different cities and regions. 【Conclusion】 The past infection rate of HEV among voluntary blood donors in China was somewhat high and with significant regional differences. The current infection rate was relatively low and had decreased compared with that in the past decade, but there was still residual risk of blood transfusion. It is necessary to pay more attention to blood HEV screening of voluntary blood donors.
