Epidemiological survey and study of hepatitis E virus among HIV-infected population in Hubei Province / 中华疾病控制杂志

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 ( 2linear=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( 2=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( 2=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) ( 2=6.169，P=0.013) , and it was also different from that in southeastern Hubei (45.79%， 49/107) ( 2=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.
