摘要:
目的 了解湖北省人类免疫缺陷病毒(human immunodeficiency virus,HIV)感染人群中戊型肝炎病毒(hepatitis E virus,HEV)的流行情况,为戊型肝炎和艾滋病防治提供有效依据。 方法 于2017年1~6月在湖北省不同地域收集335例HIV感染人群血清样本并进行抗-HEV IgM、抗-HEV IgG检测。 结果 335名HIV感染人群的抗-HEV IgG阳性率为41.49%(139/335),抗-HEV IgM阳性率为0.89%(3/335)。抗-HEV IgG阳性率与年龄无线性相关(χ趋势2=0.756,P=0.385),各年龄组间差异均无统计学意义(均有P>0.05)。男女性抗-HEV IgG阳性率差异无统计学意义(χ2=0.085,P=0.771)。CD4 ≤ 200 cell/μl与CD4>200 cell/μl两组间抗-HEV IgG阳性率差异无统计学意义(χ2=1.016,P=0.314)。三例抗-HEV IgM阳性CD4值分别为222 cell/μl,446 cell/μl和198 cell/μl。湖北省东部(30.77%,32/1 041)与中部(47.92%,46/96)HIV感染人群抗-HEV IgG阳性率差异有统计学意义(χ2=6.169,P=0.013),与东南部抗-HEV IgG阳性率差异有统计学意义(χ2=5.034,P=0.025)。 结论 湖北省HEV病毒在HIV感染人群中流行度较高,需要进行进一步研究并及时采取有效措施进行预防控制。 Abstract:Objective To determinate the seroprevalence of hepatitis E virus (HEV) exposition among HIV-infected people in Hubei Province so as to provide basic data for effective prevention and control of HIV and hepatitis E virus. Methods A total of 335 serum samples of HIV-infected people were collected from January to June 2017.Serum samples were subjected to anti-HEV IgG andanti-HEV IgM screening. Data were statistically analyzed. Results In 335 HIV-infected people, 0.89% (3/335) of serum samples were anti-HEV IgM positive and 41.49% (139/335) of them were anti-HEV IgG positive.The anti-HEV IgG positive rate was not linearly correlated with age (χ2linear=0.756, P=0.385), and there was no significant difference between the age groups (P>0.05). There was no significant difference in anti-HEV IgG positive rate between different gender(χ2=0.085, P=0.771).Anti-HEV IgG positive rate for the crowd with CD4 value ≤ 200 cell/μl was higher than that with CD4 >200 cell/μl, but showed no significant difference(χ2=1.016, P=0.314), and CD4 indexes of three positive anti-HEV IgM patients were 222, 446 and 198 in cell/μl.The anti-HEV IgG positive rate in HIV-infected population in eastern Hubei (30.77%, 32/1 041) was statistically different from that in central Hubei (47.92%, 46/96) (χ2=6.169, P=0.013), and it was also different from that in southeastern Hubei (45.79%, 49/107) (χ2=5.034, P=0.025). Conclusions There were higher HEV infection rate among HIV-infected people in Hubei Province; thus, it is essential to positively carry out double-way screening for these two diseases at the same time, and effective prevention and control of these viruses are required. -
