目的了解输血传播病毒(TTV)在老年易感人群中的感染情况。方法采用套式PCR方法,对214例老年易感人群血清进行TTV-DNA的检测。结果在214例老年易感人群中共检出71例TTV-DNA阳性血清,总检出率为33.2%,TTV-DNA阳性率与民族、性别无统计学差异(χ2=1.14,P>0.05);其中甲型肝炎老年病人中TTV-DNA阳性率为28.6%,乙型肝炎老年病人中TTV-DNA阳性率为36.0%,HBsAg(+)携带者的TTV-DNA阳性率为29.1%,各组相比差异无统计学意义(χ2=0.779,P>0.05)。结论新疆老年易感人群中存在较高的TTV感染,TTV的感染可能与肝炎有关。
Objective To understand the infection of transfusion transmitted virus (TTV) in elderly susceptible population. Methods The nested PCR method was used to detect the serum TTV-DNA in 214 senile susceptible population. Results Totally 71 cases of TTV-DNA positive sera were detected in 214 elderly susceptible population, the total positive rate was 33.2%. The positive rate of TTV-DNA was not significantly different from that of nationality and sex (χ2 = 1.14, P> 0.05). The positive rate of TTV-DNA in elderly patients with hepatitis A was 28.6%, the positive rate of TTV-DNA in elderly patients with hepatitis B was 36.0%, and the positive rate of TTV-DNA in HBsAg (+) carriers was 29.1% The difference was not statistically significant (χ2 = 0.779, P> 0.05). Conclusion There is a high prevalence of TTV infection among elderly people in Xinjiang. The infection of TTV may be related to hepatitis.
