METHODS: Seroprevalence of HBsAg, anti-HCV and anti-HIV was studied among 113 051 and 106 695 voluntary blood donors screened in 2004 and 2005, respectively. Moreover, a pilot study on 1027 HBsAg negative donors was carried out for evaluating the presence of HBV DNA by PCR on HBsAg negative/anti- HBc positive donors. RESULTS: A statistically significant increase in the prevalence of HBV (1448 vs 1768, P < 0.001), HIV (262 vs 374, P < 0.001), HCV (314 vs 372, P = 0.003) and syphilis (772 vs 853, P = 0.001) infections was noted among blood donors of Kolkata West Bengal in 2005 as compared to 2004. Moreover, the exploratory study on 1027 HBsAg negative donors revealed that 188 (18.3%)of them were anti-HBc positive out of which 21% were positive for HBV DNA. CONCLUSION: The findings of this study underscore the significantly increasing endemicity of hepatitis viruses, syphilis and HIV among the voluntary blood donors of our community. The pilot study indicates a high rate of prevalence of HBV DNA among HBsAg negative/anti-HBc positive donors and thus emphasizes the need for a more sensitive and stringent screening algorithm for blood donations.展开更多
目的探讨在人免疫缺陷病毒-1(human immunodeficiency virus-1,HIV-1)感染者中丙型肝炎病毒(hepatitis C virus,HCV)感染对于隐匿性乙型肝炎病毒(hepatitis B virus,HBV)感染的影响。方法研究对象为河南某艾滋病治疗示范区中178例乙型...目的探讨在人免疫缺陷病毒-1(human immunodeficiency virus-1,HIV-1)感染者中丙型肝炎病毒(hepatitis C virus,HCV)感染对于隐匿性乙型肝炎病毒(hepatitis B virus,HBV)感染的影响。方法研究对象为河南某艾滋病治疗示范区中178例乙型肝炎表面抗原(hepatitis B surface antigen,HBsAg)阴性的经有偿献血感染HIV-1未经抗病毒治疗的患者,检测项目包括肝功能,HBV及HCV血清标志物,HBV DNA和HCV RNA。分析HIV-1阳性,抗HCV阳性、抗HCV阴性组及HIV-1/HCV感染组中不同HCV RNA载量组HBV病原学检测结果方面的差异。结果 178例HBsAg阴性的HIV-1感染者中,HBV-M全阴性35例;单独抗HBs阳性25例;单独抗HBc阳性51例;HBsAb及HBcAb均阳性34例。抗HCV阳性HIV-1感染者与抗HCV阴性HIV-1感染者的年龄、性别比较差异无统计学意义(P>0.05);丙氨酸转移酶(alanine transaminase,ALT)、天冬氨酸氨基转移酶(aspartate aminotransferase,AST)浓度比较差异有统计学意义(P<0.05);总胆红素(total bilirubin,TBIL)浓度比较差异无统计学意义(P>0.05);乙肝标志物(HBV marker,HBV-M)阴性、单独乙肝表面抗体(hepatitis B surface antibody,HBsAb)阳性、单独乙肝核心抗体(hepatitis B core antibody,HBcAb)阳性、HBsAb及HBcAb均阳性及HBV DNA阳性例数比较差异均无统计学意义(P>0.05)。不同HCV RNA载量患者HBV DNA检测结果比较差异无统计学意义(P>0.05)。结论经有偿献血感染HIV-1人群中,HCV感染及HCV RNA载量高低与隐匿性HBV感染的发生无关;但合并HCV感染可加重HIV-1感染者的肝功能损害。展开更多
目的探讨妊娠合并隐匿性或显性乙型肝炎病毒(hepatitis B virus,HBV)感染对早产发生率的影响。方法采用前瞻性队列研究设计,以2012年6月1日至2013年3月15日间安庆市立医院所有住院分娩的孕妇为研究对象,纳入妊娠结局为单胎活产的孕妇,...目的探讨妊娠合并隐匿性或显性乙型肝炎病毒(hepatitis B virus,HBV)感染对早产发生率的影响。方法采用前瞻性队列研究设计,以2012年6月1日至2013年3月15日间安庆市立医院所有住院分娩的孕妇为研究对象,纳入妊娠结局为单胎活产的孕妇,收集其血清并进行HBV表面抗原和HBV S基因片段的检测,并通过医院电子病历系统收集孕妇人口学信息等资料,采用单因素和多因素统计方法分析妊娠合并隐匿性和显性HBV感染对早产发生率的影响。结果孕妇早产发生率为21.00%(189/900);其中隐匿性HBV感染组、显性HBV感染组和非HBV感染组孕妇在人口学特征方面相似可比,其早产发生率分别为20.51%(16/78)、20.00%(14/70)、21.14%(159/752)。单因素与多因素分析未发现早产发生率与HBV感染相关,以非HBV感染组为参照,多因素COX回归分析发现显性HBV感染、隐匿性HBV感染与早产间调整后相对危险度(adjusted risk ratio,RRa)分别为1.03(0.81,1.32)和0.99(0.78,1.25);以同样参照,多因素线性回归分析发现孕周与HBV感染状况的回归系数β为0.09(-0.14,0.31)。结论妊娠合并隐匿性或显性HBV感染与早产的发生率无明显相关。展开更多
