Human immunodeficiency virus (HIV/AIDS) infected patients have a higher risk of opportunistic infections (OIs) depending on their immunological status, especially CD4 + cell count. Toxoplasma gondii, hepatitis C virus (HCV), and hepatitis B virus (HBV) are important OIs among Human Immunodeficiency Virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS) patients. However, little is known about co-infection of these pathogens among HIV-infected individuals and their correlation with the patient's CD4 + cell count. Hence, this study aimed to investigate the serological and molecular status of T. gondii infection among HIV-infected individuals who had co-infection with HBV and HCV infections.
A total of 100 HIV/AIDS patients in two cities in the southwest of Iran was tested for T. gondii Immunoglobulin G (IgG) and Immunoglobulin M (IgM) antibodies as well as DNA detection by polymerase chain reaction (PCR) targeting the RE gene. HBV and HCV were detected by hepatitis B surface antigen (HBsAg) test, hepatitis C antibody (HCV Ab) test, and Real-Time PCR. The number of CD4 + cell counts was determined by Flow cytometry.
Anti-T. gondii IgG was positive in 22% of the patients, but anti-T. gondii IgM and PCR were negative in all samples. HBV and HCV were positive in 8% and 33% of the patients, respectively. Co-infections were as followed: HIV + HCV (16%), HIV + HCV + T. gondii (11%), HIV + T. gondii (5%), HIV + HBV (1%), HIV + HBV + T. gondii (1%), HIV + HBV + HCV (1%), and HIV + HBV + HCV + T. gondii (5%). A significant decline in CD4 + cell counts was found in such co-infection groups (HIV + T. gondii, HIV + HCV + T. gondii, and HIV + HBV + HCV + T. gondii) compared with the HIV mono-infection group.
Our study showed that co-infections of T. gondii, HCV, and HBV were common among HIV-infected patients and co-infections had a negative correlation with CD4 + cell counts of the patients.
人类免疫缺陷病毒(HIV/AIDS)感染患者的机会性感染(OIs)风险较高,这取决于他们的免疫状态,尤其是 CD4+细胞计数。弓形体、丙型肝炎病毒(HCV)和乙型肝炎病毒(HBV)是 HIV/AIDS 患者中重要的 OIs。然而,对于 HIV 感染个体中这些病原体的合并感染以及它们与患者 CD4+细胞计数的相关性,人们知之甚少。因此,本研究旨在调查感染 HIV 的个体中弓形体感染的血清学和分子状态,这些个体同时合并感染 HBV 和 HCV。
对伊朗西南部两个城市的 100 名 HIV/AIDS 患者进行了检测,以检测 IgG 和 IgM 抗体以及聚合酶链反应(PCR)针对 RE 基因的 DNA 检测。通过乙型肝炎表面抗原(HBsAg)检测、丙型肝炎抗体(HCV Ab)检测和实时 PCR 检测 HBV 和 HCV。通过流式细胞术确定 CD4+细胞计数。
22%的患者抗弓形体 IgG 阳性,但所有样本的抗弓形体 IgM 和 PCR 均为阴性。HBV 和 HCV 的阳性率分别为 8%和 33%。合并感染如下:HIV+HCV(16%)、HIV+HCV+弓形体(11%)、HIV+弓形体(5%)、HIV+HBV(1%)、HIV+HBV+弓形体(1%)、HIV+HBV+HCV(1%)和 HIV+HBV+HCV+弓形体(5%)。与 HIV 单一感染组相比,在这些合并感染组(HIV+弓形体、HIV+HCV+弓形体和 HIV+HBV+HCV+弓形体)中发现 CD4+细胞计数显著下降。
我们的研究表明,HIV 感染患者中弓形体、HCV 和 HBV 的合并感染很常见,合并感染与患者的 CD4+细胞计数呈负相关。
