A reduction in new human immunodeficiency virus(HIV) cases is one of the ten areas prioritized by the United Nations Program on HIV. However, recent official reports confirm the HIV rate is increasing and predicted a huge incidence in the near future in Iran, despite the preventative program by Iran's Health Ministry. In this descriptive study, we evaluate the frequency of HIV positive cases among referral patients to a private clinic laboratory for its diagnosis in addition to specimens from other laboratories. An epidemiological analysis is also performed.
In this descriptive study, the total number of patients was 138 cases that referred for the diagnosis of HIV to the private Laboratory. Of these, 93 males (67.4%) and 45 females (32.6%) voluntarily requested to be examined for specific increases in specific antibody titer, western blot assays and RNA quantitation polymerase chain reaction. We collected two separate tubes of whole blood, one for reverse transcriptasepolymerase chain reaction analysis and the second one for the remaining two tests. Those patients who were antibody positive by western blot and/or reverse transcriptase-polymerase chain reaction(RT-PCR) analyses were considered as HIV positive cases.
There were 18.84% confirmed HIVcases (17.39% males; 1.45% females). Analysis of the results confirmed that the ratio of male to female patients in the infected group was not comparable to those in the suspect group. The majority of HIV positive cases were either infected by their partner via sexual intercourse (84.61%) or needle sticks (11.53%) among the drug addicted group. The infection routes of the remainder were unknown.
Analysis of the data revealed a higher frequency of HIVin males than females among the tested group. There was a shift in to unsafe sexual intercourse as seen in the present study. The higher rate of infected male patients shows a shift in transmission route to unsafe intercourse. Therefore, it is necessary to design new supportive programs by actively identifying and contacting at-risk groups, particularly infected females who are uninterested in being and monitored.
减少新的人类免疫缺陷病毒(HIV)病例是联合国艾滋病毒规划的十个重点领域之一。然而,最近的官方报告证实,尽管伊朗卫生部开展了预防计划,但伊朗的 HIV 感染率正在上升,并预计在不久的将来会出现大量病例。在这项描述性研究中,我们评估了一家私人诊所实验室对转介患者进行 HIV 诊断的阳性病例频率,以及来自其他实验室的标本。还进行了流行病学分析。
在这项描述性研究中,总共有 138 例患者因特定抗体滴度、western blot 检测和 RNA 定量聚合酶链反应的特异性增加而自愿要求到私人实验室进行诊断。我们收集了两管全血,一管用于逆转录聚合酶链反应分析,另一管用于其余两项检测。通过 western blot 和/或逆转录聚合酶链反应(RT-PCR)分析抗体阳性的患者被认为是 HIV 阳性病例。
有 18.84%的病例确诊为 HIV 感染(男性占 17.39%,女性占 1.45%)。结果分析证实,感染组的男女患者比例与疑似组的男女患者比例无差异。大多数 HIV 阳性病例是通过性接触(84.61%)或吸毒者的针具刺伤(11.53%)感染的。其余病例的感染途径不明。
数据分析显示,在接受检测的人群中,男性感染 HIV 的频率高于女性。在本研究中,不安全的性行为也有所增加。感染男性患者的比例较高表明,传播途径已转向不安全的性行为。因此,有必要通过积极识别和接触高危人群,特别是对监测不感兴趣的感染女性,制定新的支持性计划。
