This case-control study aimed to characterize the factors associated with amebiasis, defined as presence of anti-Entamoeba histolytica antibody titers of ≧ 128 by indirect hemagglutination assay, among persons seeking voluntary counseling and testing (VCT) for human immunodeficiency virus (HIV) infection. Between April 2006 and September 2009, 57 of 4,802 persons (1.2%) seeking VCT services were seropositive for E. histolytica infection. Compared with 228 seronegative controls, case subjects were older (odds ratio [OR] for per 1-year increase, 1.098; 95% confidence interval [CI], 1.036, 1.165), less likely to hold bachelor degree or higher (OR, 0.359; 95% CI, 0.152, 0.846), and were more likely to be men who have sex with men (MSM) (OR, 8.382; 95% CI, 2.050, 34.266) and have oral-anal sex (OR, 4.016; 95% CI, 1.711, 9.427) in multiple logistic regression analysis. The MSM, fecal-oral contamination, lower educational achievement, and older age were associated with increased risk for amebiasis among persons seeking VCT for HIV infection.
本病例对照研究旨在描述与阿米巴病相关的因素，阿米巴病定义为间接血凝试验抗体滴度≧128。研究对象为在寻求人免疫缺陷病毒（HIV）感染自愿咨询检测（VCT）服务的人群中，4802 名寻求 VCT 服务者中有 57 人（1.2%）血清抗 Entamoeba histolytica 抗体阳性。与 228 名血清阴性对照者相比，病例组年龄更大（每增加 1 岁的比值比[OR]，1.098；95%置信区间[CI]，1.036，1.165），获得学士学位或更高学历的可能性更小（OR，0.359；95%CI，0.152，0.846），更有可能是男男性行为者（MSM）（OR，8.382；95%CI，2.050，34.266），肛交（OR，4.016；95%CI，1.711，9.427）。在多因素逻辑回归分析中，MSM、粪口污染、教育程度低和年龄大与 HIV 感染者 VCT 中阿米巴病的风险增加相关。
