The proportion of new diagnoses of HIV infection in immigrants residing in Italy raised from 11% in 1992 to 29.7% in 2018. To investigate the HIV clades circulating in this community a retrospective study was performed in 557 HIV-infected immigrants living in 12 Italian cities. Immigrants originated from East-Europe and Central-Asia (11.7%), North Africa and Middle East (7.3%), South and South-East Asia (7.2%), Latin America and the Caribbean (14.4%), and sub-Saharan Africa (59.4%). More than 87% of immigrants were on antiretroviral therapy (ART), although 26.6% of them were viremic. A 22.0% of immigrants had hepatitis (HBV and/or HCV) and/or tuberculosis. HIV phylogenetic analysis on sequences from 192 immigrants showed the presence of clades B (23.4%), G (16.1%), C (10.4%), A1 (9.4%), F1 (5.2%), D (1.6%) and Circulating Recombinant Forms (CRFs) (33.9%). CRF02_AG represented 72.3% of the total CRFs. Clusters between immigrants and Italian natives were also present. Drug resistance mutations to NRTI, NNRTI, and PI drug classes occurred in 29.1% of ART-treated and in 12.9% of ART-naïve individuals. These data highlight the need for tailored public health interventions in immigrants to avoid spreading in Italy of HIV genetic forms and ART-resistant variants, as well as HIV co-morbidities.
意大利移民中新诊断出的 HIV 感染比例从 1992 年的 11%上升到 2018 年的 29.7%。为了调查该人群中流行的 HIV 株系,对居住在意大利 12 个城市的 557 名 HIV 感染移民进行了回顾性研究。移民来自东欧和中亚(11.7%)、北非和中东(7.3%)、南亚和东南亚(7.2%)、拉丁美洲和加勒比地区(14.4%)和撒哈拉以南非洲(59.4%)。超过 87%的移民正在接受抗逆转录病毒治疗(ART),但其中 26.6%的人存在病毒血症。22.0%的移民患有肝炎(HBV 和/或 HCV)和/或结核病。对 192 名移民的序列进行 HIV 系统发育分析显示存在 B (23.4%)、G (16.1%)、C (10.4%)、A1 (9.4%)、F1 (5.2%)、D (1.6%)和 Circulating Recombinant Forms (CRFs)(33.9%)。CRF02_AG 占总 CRFs 的 72.3%。移民和意大利本地人之间也存在聚类。在接受 ART 治疗的人群中,有 29.1%的人出现了对 NRTI、NNRTI 和 PI 类药物的耐药突变,而在未接受 ART 治疗的人群中,有 12.9%的人出现了耐药突变。这些数据强调了需要针对移民采取有针对性的公共卫生干预措施,以避免意大利 HIV 遗传形式和抗药性变异体以及 HIV 合并症的传播。
