Differences in neutralizing antibody sensitivities and envelope characteristics indicate distinct antigenic properties of Nigerian HIV-1 subtype G and CRF02_AG. Virol J 2024; 21:148.

Abstract
The magnitude of the HIV-1 epidemic in Nigeria is second only to the subtype C epidemic in South Africa, yet the subtypes prevalent in Nigeria require further characterization. A panel of 50 subtype G and 18 CRF02_AG Nigerian HIV-1 pseudoviruses (PSV) was developed and envelope coreceptor usage, neutralization sensitivity and cross-clade reactivity were characterized. These PSV were neutralized by some antibodies targeting major neutralizing determinants, but potentially important differences were observed in specific sensitivities (eg. to sCD4, MPER and V2/V3 monoclonal antibodies), as well as in properties such as variable loop lengths, number of potential N-linked glycans and charge, demonstrating distinct antigenic characteristics of CRF02_AG and subtype G. There was preferential neutralization of the matched CRF/subtype when PSV from subtype G or CRF02_AG were tested using pooled plasma. These novel Nigerian PSV will be useful to study HIV-1 CRF- or subtype-specific humoral immune responses for subtype G and CRF02_AG.

Abstract
The wide variety of new HIV-1 recombinant variants are a predominant challenge for understanding the molecular epidemiology and preventing the spread of the HIV-1 epidemic. In this study, we confirmed a novel HIV-1 unique B/C recombinant (ZLQ01186) isolated from a male patient infected with HIV-1 through injection drug use in Foshan city, Guangdong Province. The near full-length genome was amplified, and then the polymerase chain reaction products were sequenced by Sanger sequencing. The genomic sequence of the strain, with two subtype B segments inserted into the subtype C backbone, was 8,953 bp in length, extending from 647 to 9,599 bp according to the HXB2 genome. In addition, this B/C recombinant strain contained the non-nucleoside reverse transcriptase inhibitor resistance mutation K103N and the integrase strand transfer inhibitor other resistance mutation L74I according to the Stanford University HIV Drug Resistance Database program. The drug resistance profile indicates high-level resistance against efavirenz and rilpivirine. This study identified a recombinant between the main circulating strains, indicating a more complicated trend of the HIV-1 epidemic in Guangdong, China.

Lan Y, Xin R, Cai W, Deng X, Li L, Li F, Cai X, Tang X, Fan Q, Hu F. Characteristics of drug resistance in HIV-1 CRF55_01B from ART-experienced patients in Guangdong, China. J Antimicrob Chemother 2021; 75:1925-1931. [PMID: 32300784 DOI: 10.1093/jac/dkaa116] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2019] [Revised: 02/27/2020] [Accepted: 03/03/2020] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND HIV-1 acquired drug resistance (ADR) has become a critical clinical and public health issue. Recently, HIV-1 CRF55_01B has been found more frequently in the MSM population. OBJECTIVE To investigate the characteristics of HIV-1 drug resistance mutations (DRMs) and the extent of changes in drug susceptibility among ART-experienced CRF55_01B-infected adults of Guangdong. METHODS ADR was tested for immediately in CRF55_01B-infected patients with virological failure. Demographic and epidemiological information was collected. DRMs and antiretroviral susceptibility were interpreted using the Stanford University HIV Drug Resistance Database HIVdb program. RESULTS Overall, 162 (4.78%) CRF55_01B isolates were identified from 2013 to 2018. Among DRMs, M184V (43.83%) was the most frequent NRTI DRM, followed by K65R (23.46%), and V179E (98.77%) was the most frequent NNRTI DRM, followed by K103N (47.53%) and Y181C (14.81%). According to the HIVdb program, 79.01% of the CRF55_01B-infected patients carried mutations conferring low-level or higher drug resistance to any of the three classes of ART drugs. Among PI DRMs, only one mutation affording low-level resistance to nelfinavir was found (0.62%). Among NRTI DRMs, a high proportion of high-level resistance to lamivudine (58.64%) and emtricitabine (58.02%) was found. As regards NNRTIs, more than 75% of patients carried efavirenz and nevirapine DRMs. The percentages of high-level resistance were 70.99%, 63.58%, 22.22%, 17.90% and 4.32% for nevirapine, efavirenz, rilpivirine, doravirine and etravirine, respectively. CONCLUSIONS High frequencies of DRMs and resistance were observed among CRF55_01B-infected patients failing ART in Guangdong, and interventions may be considered to minimize ecological contributions to ART.
