India contributes heavily to the global burden of visceral leishmaniasis (VL, kala-azar) and human immunodeficiency virus (HIV)/AIDS. The prevalence of HIV seropositivity in VL patients at a tertiary care centre in northern India, as observed during a prospective study over a period of 2 years, is presented. Of the 104 cases of VL/post-kala-azar dermal leishmaniasis, six (5.7 %) were found to be HIV positive, compared to 11 (5.5 %) seropositive for HIV of 198 patients with fever due to other causes. Four of the six (67 %) VL/HIV co-infected patients had a chronic/relapsing course, not responding to antileishmanial treatment. A CD4 T-cell count of < 200 mm(-3) was found in four of the five (80 %) co-infected patients in whom the test was done. Although the level of HIV/VL co-infection in the present study was lower than that of Mediterranean countries, there is a trend towards rising co-infection. The VL-endemic states of India have a huge population of migrant labourers, who work in high-HIV-prevalence states. The reported increase in the prevalence of HIV in the VL-endemic, populous states of India is a cause of grave concern, and co-infection may assume epidemic proportions in the coming decade if left unchecked.
印度在全球内脏利什曼病(VL,黑热病)和人类免疫缺陷病毒(HIV)/艾滋病负担中占很大比例。本文呈现了在印度北部一家三级医疗中心进行的为期2年的前瞻性研究中观察到的VL患者的HIV血清阳性率。在104例VL/黑热病后皮肤利什曼病病例中,有6例(5.7%)被发现HIV呈阳性,相比之下,198例因其他原因发热的患者中有11例(5.5%)HIV血清呈阳性。6例VL/HIV合并感染患者中有4例(67%)病程呈慢性/复发型,对抗利什曼原虫治疗无反应。在进行检测的5例合并感染患者中,有4例(80%)的CD4 T细胞计数<200/mm³。尽管本研究中HIV/VL合并感染水平低于地中海国家,但合并感染有上升趋势。印度VL流行地区有大量流动劳工,他们在HIV高流行地区工作。据报道,印度VL流行且人口众多的邦中HIV患病率上升,这令人严重关切,如果不加以控制,合并感染在未来十年可能会呈流行态势。
