摘 要:目的比较HCV单感染、人类免疫缺陷病毒(HIV)/HCV共感染、HCV自发清除者血清HCV抗体S/CO比值低值与高值的分布情况,对HCV不同感染状态下HCV抗体检测的临床意义进行初步评价。方法2009年对河南上蔡某村的129例HCV单感染者、98例HIV/HCV共感染者、65例HIV阴性的HCV自发清除者和48例HIV阳性的HCV自发清除者的血清或血浆样本进行HCV抗体、HCVRNA、ALT、AST检测,对HCV慢性感染者和HIV感染者分别进行HCV基因型分析和CD4+T淋巴细胞计数检测,将各组人群的各项指标进行对比分析。2012年对该调查人群进行随访采样并检测HCV抗体水平。计量资料组间比较采用t检验,计数资料采用疋。检验;相关分析采用Pearson检验。结果HCV慢性感染者的HCV抗体水平几乎均为高值分布(S/CO≥10),而HCV抗体低值(1≤S/CO〈10)主要分布在HCV自发清除者和HIV/HCV共感染者中;HCV自发清除者的抗体水平随着时间推移发生衰减(2012年与2009年比:HIV阴性组:5.51土3.67与7.75±3.8,f=10.67,P〈0.01;HIV阳性组:4.93±3.35与7.61±3.47,t=9.52,P〈0.01),而HCV慢性感染者无此变化;HIV/HCV共感染者的HCV抗体S/CO比值与CD4+T淋巴细胞数呈正相关(r=0.28,P=0.008)。比较不同HCV基因型的慢性感染者,HCV单感染组HCV-lb型患者的HCV抗体水平高于HCV-2a型(14.74±1.68与14.08±1.44,t=2.20,P=0.03);HIV/HCV共感染者中,HCV—Ib型血浆ALT/AST水平升高的患者比例显著高于HCV-2a型(ALT:25/42与16/56,x^2=9.45,P=0.002;AST:28/42与18/56,x^2=11.49,P=0.001)。将HCV抗体水平、HCVRNA以及血浆ALT/AST检测结果联合分析,无论是否合并HⅣ感染,HCV抗体高值组的HCVRNA阳性率显著高于HCV抗体低值组(HIV阴性:128/151与1/43,z。=102.11,P〈0.01;HIV阳性:88/98与10/48,x^2=69.44,P〈0.01�Objective To investigate the potential of hepatitis C virus (HCV) antibody measurement as a clinical approach to determine the infection status and potential for spontaneous-resolution among patients with HCV mono-infection and HCV/human immunodeficiency virus (HIV) co-infection. Methods A total of 340 individuals who tested positive for serum anti-HCV antibodies and/or serum anti-HIV antibodies were enrolled for study in 2009 from a single village in central China. Markers of liver function (alanine aminotransferase (ALT) and aspartate aminolransfemse (AST)) and infection (anti-HCV antibodies, CD4+ T cell counts, HCV genotype, and HCV viral load) were measured at baseline and follow-up (in July 2012). At follow-up, the subjects were grouped according to ongoing HCV mono-infection (n = 129), ongoing HCV/HIV co-infection (17 = 98), spontaneously resolved (SR)-HCV in mono-infection (n = 65), and SR-HCV in HCV/I-IIV co-infection (n = 48) for statistical analysis. Results Almost all of the subjects in the ongoing HCV mono-infection group showed high levels of HCV antibodies (S/CO 1〉 10), but the majority of the subjects in the SR-HCV in mono-infection group and in the ongoing HCV/HIV co-infection group. The SR-HCV mono-infection group showed a remarkable decrease in HCV antibodies from 2009 (HIV-: 7.75± 3.8; HIV+: 7.61 ±3.47) to 2012 (HIV: 5.51 ±3.67; HIV+: 4.93 ±3.35) (HIV: t = 10.67, P 〈 0.01; I-IV+: t = 9.52, P 〈 0.01). The ongoing HCV/HIV co-infection group showed a positive correlation between HCV antibodies S/CO ratio and CD4+ T cell count (r = 0.28,P = 0.008). In the ongoing HCV mono-infection group, the levels of HCV antibodies were significantly higher in individuals infected with HCV-lb than in those with HCV-2a (14.74 :L 1.68 vs. 14.08 q- 1.44, t = 2.20,P = 0.03). In the ongoing HCV/HIV co-infection group, the numbers of subjects with elevated (〉 40 U/L) liver function markers were significantly
