Abstract
The implementation of pretreatment drug-resistance (PDR) surveillance among people living with HIV-1 (PLWH) is a top priority in countries using efavirenz (EFV)/nevirapine (NVP) for first-line ART. In this study, we assessed the prevalence of PDR among PLWH in Shanghai, China during 2017-2021, and to reveal PDR transmission between Shanghai and other regions of China. A total of 5050 PLWH not on ART during 2017-2021 were included. Partial HIV-1 pol sequences were amplified, sequenced, and analysed for drug-resistance mutations (DRMs). Besides, transmission network of PDR variants was inferred using HIV-TRACE. The overall prevalence of PDR was 4.8% (242/5050; 95% CI, 4.2-5.4). Prevalence of NNRTI-associated PDR was 3.9% (95% CI, 3.4-4.5), higher than those of NRTI-associated (0.8%; 95% CI, 0.5-1.1) and PI-associated PDR (0.9%; 95% CI, 0.6-1.2). High prevalence of PDR (especially high-level resistance) to EFV (132/5050, 2.6%) and NVP (137/5050, 2.7%) were found. CRF01_AE (46.0%) was the predominant HIV-1 genotype with any DRMs, followed by CRF55_01B (21.0%), and CRF07_BC (15.1%). Two NRTI-associated (S68G/N/R and T215A/N/S/Y), five NNRTI-associated (V179D/E/T/L, K103N/R/S/T, E138A/G/K, V106M/I/A and Y181C/I) and two PI-associated mutations (M46I/L/V and Q58E) were the most common observed DRMs in PDR patients in Shanghai. The vast majority of S68G occurred in CRF01_AE (45%). M46I/L/V and Q58E showed a relatively high prevalence in CRF01_AE (4.1%) and CRF07_BC (12.6%). Transmission network analyses demonstrated cross-regional transmission links of PDR variants between Shanghai and other regions of China, which was mainly driven by the potential low-level DRM V179D/E. These results provide crucial information for clinical decision making of first-line ART in PLWH with PDR.

Application of molecular epidemiology in revealing HIV-1 transmission network and recombination patterns in Tianjin, China. J Med Virol 2024; 96:e29824. [PMID: 39072805 DOI: 10.1002/jmv.29824] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2024] [Revised: 06/24/2024] [Accepted: 07/16/2024] [Indexed: 07/30/2024]
Abstract
Using a comprehensive molecular epidemiological approach, we characterized the transmission dynamics of HIV-1 among the MSM population in Tianjin, China. Our findings revealed that 38.56% (386/1001) of individuals clustered across 109 molecular transmission clusters (TCs), with MSM aged 50 and below being the group most commonly transmitting HIV-1. Among the identified TCs, CRF01_AE predominated, followed by CRF07_BC. Notably, CRF07_BC demonstrated a higher propensity for forming large clusters compared to CRF01_AE. Birth-death skyline analyses of the two largest clusters indicated that the HIV/AIDS transmission may be at a critical point, nearly all had Re approximately 1 by now. A retrospective analysis revealed that the rapid expansion of these large clusters was primarily driven by the introduction of viruses in 2021, highlighting the crucial importance of continuous molecular surveillance in identifying newly emerging high-risk transmission chains and adapting measures to address evolving epidemic dynamics. Furthermore, we detected the transmission of drug-resistant mutations (DRMs) within the TCs, particularly in the CRF07_BC clusters (K103N, Y181C, and K101E) and CRF01_AE clusters (P225H and K219R), emphasizing the importance of monitoring to support the continued efficacy of first-line therapies and pre-exposure prophylaxis (PrEP). Recombination analyses indicated that complex recombinant patterns, associated with increased amino acid variability, could confer adaptive traits to the viruses, potentially providing a competitive advantage in certain host populations or regions. Our study highlights the potential of integrating molecular epidemiological and phylodynamic approaches to inform targeted interventions.

Retrospective Study on Genetic Diversity and Drug Resistance among People Living with HIV at an AIDS Clinic in Beijing. Pharmaceuticals (Basel) 2024; 17:115. [PMID: 38256948 PMCID: PMC10819489 DOI: 10.3390/ph17010115] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 01/03/2024] [Accepted: 01/10/2024] [Indexed: 01/24/2024] Open
Abstract
(1) Background: The objective of this study was to investigate the prevalence of genetic diversity and drug resistance mutations among people living with HIV (PLWH) attending clinics in Beijing. (2) Methods: A retrospective analysis was conducted on PLWH admitted to the Fifth Medical Center of People's Liberation Army (PLA) General Hospital between 1 March 2013 and 31 July 2020. The participants were analyzed for pretreatment drug resistance (PDR) and acquired drug resistance (ADR). Nested polymerase chain reaction (PCR) was utilized to amplify the pol gene from plasma RNA samples obtained from the participants. Genotypic and HIV drug resistance were determined using the Stanford University HIV Drug Resistance Database. Univariate and multifactorial logistic analyses were used to assess the risk factors for PDR. (3) Results: The overall prevalence rates of PDR and ADR were 12.9% and 27.8%, respectively. Individuals treated with non-nucleoside reverse transcriptase inhibitors (NNRTIs) exhibited the highest prevalence of mutations. Specific mutation sites, such as V179D for NNRTIs and M184V and K65R for nucleoside reverse transcriptase inhibitors (NRTIs), were identified as prevalent mutations. Individuals treated with efavirenz (EFV) and nevirapine (NVP) were found to be susceptible to developing resistance. The multifactorial regression analyses indicated that the factors of circulating recombination form (CRF) genotype CRF07-BC and a high viral load were associated with an increased risk of PDR. CRF01-AE and CRF07-BC were the most prevalent HIV genotypes in our study. (4) Conclusions: The distribution of HIV genotypes in Beijing is complex. There is a need for baseline screening for HIV drug resistance among ART-naive individuals, as well as timely testing for drug resistance among ART-experienced individuals.

Drug Des Devel Ther 2023; 17:1485-1494. [PMID: 37220545 PMCID: PMC10200113 DOI: 10.2147/dddt.s406255] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Accepted: 04/29/2023] [Indexed: 05/25/2023] Open
Abstract
Purpose The genetic diversity and genetic predisposition for drug resistance mutations are the primary features of human immunodeficiency virus type 1 (HIV-1), which could cause the incidence of failure of antiretroviral therapy (ART). This study investigates the distribution of various HIV-1 genotypes and the incidence of pretreatment drug resistance (PDR) in the antiretroviral-naive HIV-1 infected participants in Xi'an, China. Patients and Methods In this study, a cross-sectional analysis was carried out at the Xi'an Eighth Hospital between January 2020 and December 2021 among newly-diagnosed ART-naive HIV-1 infected participants. A nested PCR technique was used for amplifying the target segment of 1.3 kb present in the pol gene that spanned the reverse transcriptase and the protease regions. HIV-1 genotypes and the PDR-associated mutations were identified using the Stanford HIV Drug Resistance Database. Results A total of 317 pol gene sequences were retrieved, amplified, and sequenced. The circulating recombinant form (CRF), CRF07_BC (51.7%) was seen to be the most prevalent HIV-1 genotype, followed by other genotypes like CRF01_AE (25.9%), B (14.2%), and CRF55_01B (4.7%). PDR was found in 18.3% of the population. The PDR mutation frequency in the non-nucleoside reverse transcriptase inhibitor (NNRTI) (16.1%) was significantly higher compared to that of the nucleoside reverse transcriptase inhibitor (NRTI) (4.4%) and the protease inhibitor (0.9%). V179D/E (both were 4.4%) was seen to be the most predominant type of NNRTI mutation. K65R and M184V (1.3%) were the most frequent NRTI-associated mutations. About half (48.3%) of the sequenced HIV-1 strains that had mutations could show a potential low-level NNRTI resistance owing to V179D/E. Multivariate regression analysis revealed one PDR mutation associated with subtype CRF01_AE (p=0.002) and CRF55_01B (p<0.001) as a higher risk mutation. Conclusion Diverse and complex HIV-1 genotypes are distributed in Xi'an, China. Considering new evidence, it is necessary to screen for baseline HIV-1 drug resistance among the newly-diagnosed HIV-1 individuals.

Abstract
During the routine surveillance of HIV-1 pretreatment drug resistance in Beijing, five men who have sex with men (MSM) and a woman were observed to get infected by newly identified CRF103_01B strain. To elucidate the genetic characteristics, the near full-length genome (NFLG) was obtained. Phylogenetic inference indicated that CRF103_01B NFLG was composed of six mosaic segments. Segments IV and V of CRF103_01B were located among the clusters subtype B and CRF01_AE (group 5), respectively. The CRF103_01B strain was deduced to originate from Beijing MSM population around 2002.3-2006.4 and continued to spread among MSM population at a low level, then to the general population via heterosexual contact in northern China. Molecular epidemiology surveillance of CRF103_01B should be reinforced.

Abstract
BACKGROUND HIV drug resistance increased with the widespread use of antiretroviral drugs, and posed great threat to antiretroviral therapy (ART). Pu'er Prefecture, lying in the southwest of Yunnan Province, China, borders Myanmar, Laos and Vietnam, is also the area where AIDS was discovered earlier, however, in which there has been no information on HIV drug resistance. METHODS A cross-sectional survey of pretreatment drug resistance (PDR) was conducted in Pu'er Prefecture in 2021. Partial pol gene sequences were obtained to analyze drug resistance and construct genetic transmission network. HIV drug resistance was analyzed using the Stanford University HIVdb algorithm. RESULTS A total of 295 sequences were obtained, among which 11 HIV-1 strain types were detected and CRF08_BC (62.0%, 183/295) was the predominant one. Drug resistance mutations (DRMs) were detected in 42.4% (125/295) of the sequences. The prevalence of PDR to any antiretroviral drugs, nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitors (PIs) were 10.8% (32/295), 9.5% (28/295), 1.0% (3/295) and 0.3% (1/295), respectively. The risk of PDR occurrence was higher among individuals with CRF01_AE strain types. HIV-1 molecular network was constructed, in which 56.0% (42/75) of links were transregional, and 54.7% (41/75) of links were associated with Lancang County. Among the sequences in the network, 36.8% (35/95) harbored DRMs, and 9.5% (9/95) were drug resistance strains. Furthermore, 8 clusters had shared DRM. CONCLUSION The overall prevalence of PDR in this study was in a moderate level, but NNRTIs resistance was very approaching to the threshold of public response initiation. PDR was identified in the transmission network, and DRMs transmission was observed. These findings suggested that the consecutive PDR surveillance should be conducted in this region.

Epidemic Characteristics of HIV Drug Resistance in Hefei, Anhui Province. Pathogens 2022; 11:pathogens11080866. [PMID: 36014987 PMCID: PMC9416635 DOI: 10.3390/pathogens11080866] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 07/22/2022] [Accepted: 07/25/2022] [Indexed: 02/04/2023] Open
Abstract
To study the characteristics of HIV pretreatment drug resistance (PDR) and acquired drug resistance (ADR) in Hefei, a cross-sectional survey was used to collect 816 samples from newly reported HIV infections from 2017 to 2020 and 127 samples from HIV infections with virological failure from 2018 to 2019 in Hefei. HIV drug resistance levels and drug resistance mutations were interpreted using the Stanford Drug Resistance Database. Molecular networks were constructed by HIV-TRACE. Among the newly reported infections in Hefei, the prevalence of PDR was 6.4% (52/816). The drug resistance mutations were mainly V179E/D/T (12.4%), K103N (1.3%), and V106I/M (1.3%). In addition, it was found that the CRF55_01B subtype had a higher drug resistance rate than other subtypes (p < 0.05). Molecular network analysis found that K103N and V179E may be transmitted in the cluster of the CRF55_01B subtype. The prevalence of ADR among HIV infections with virological failure was 38.6% (49/127), and the drug resistance mutations were mainly M184V (24.4%), K103N/S (15.7%), Y181C (11.0%), G190S/A/E (10.2%), and V106M/I (10.2%). The molecular network was constructed by combining HIV infections with virological failure and newly reported infections; M184V and Y181C may be transmitted between them. The chi-square trend test results indicated that the higher the viral load level, the greater the number of newly reported infections linked to the infections with virological failure in the molecular network. In conclusion, interventions should focus on infections of the CRF55_01B subtype to reduce the transmission of drug-resistant strains. However, improving the treatment effect of HIV infections is beneficial for reducing the second-generation transmission of HIV.

Abstract
Objectives The emergence of pretreatment drug resistance (PDR) caused by increased usage of antiretroviral therapy (ART) represents a significant challenge to HIV management. In this study, we evaluated the prevalence of PDR in people living with HIV (PLWH) in Chongqing, China. Methods We retrospectively collected the data of 1110 ART‐naïve PLWH in Chongqing from January 1, 2018 to June 30, 2021. HIV‐1 genotypes and drug resistance were analyzed using the HIV‐1 pol sequence. Risk factors associated with PDR were evaluated via the logistic regression model. Results Nine genotypes were detected among 1110 participants, with CRF07_BC (55.68%) being the dominant genotype, followed by CRF01_AE (21.44%), CRF08_BC (14.14%), and other genotypes (8.74%). Of all the participants, 24.14% exhibited drug resistance mutations (DRMs). The predominant DRMs for non‐nucleoside reverse transcriptase inhibitors (NNRTIs) and nucleoside reverse transcriptase inhibitors (NRTIs) were V179D/E/A/DIN (13.60%) and M184V/I (1.44%), respectively, whereas only two major DRMs (M46L and I54L) were identified for protease inhibitors (PIs). The total prevalence of PDR was 10.54%, with 2.43%, 7.66%, and 1.71% participants exhibiting PDR to NRTIs, NNRTIs, and PIs, respectively. Furthermore, female PLWH, delays in ART initiation, and the CRF08_BC genotype were associated with a higher risk of PDR. Conclusions Our study provides the first large cohort data on the prevalence of PDR in Chongqing, China. HIV‐1 genotypes are diverse and complex, with a moderate level of PDR, which does not reach the threshold for the initiation of a public health response. Nevertheless, continuous surveillance of PDR is both useful and advisable.

[PMID: 35293099 DOI: 10.1111/hiv.13252] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Revised: 10/19/2021] [Accepted: 01/07/2022] [Indexed: 11/30/2022]
Abstract
OBJECTIVES This study investigated the prevalence and patterns of pre-treatment and acquired HIV drug resistance mutations among people living with HIV (PLWH) on antiretroviral therapy (ART) for 12 (±3) months in Tianjin, China. METHODS From Jan 2018 to Dec 2020, PLWH with HIV-1 RNA greater than 1000 copies/mL visiting the ART clinic in the Tianjin Second People's Hospital were enrolled. Viral RNA isolated from blood samples were taken for genotypic resistance testing using an in-house method. Major drug resistance mutations were analyzed for reverse transcriptase and protease Sanger sequences using the Stanford University HIV Drug Resistance Database. Multivariable Poisson regressions were used to evaluate the factors associated with drug resistance mutations. RESULTS HIV drug resistance testing was successfully performed on 584 ART-naive and 71 ART-experienced participants. Pre-treatment drug resistance mutation prevalence was 13.5% (79/584) to any antiretroviral drug, 12.5% (73/584) to non-nucleoside reverse transcriptase inhibitors (NNRTIs), 1.5% (9/584) to nucleoside reverse-transcriptase inhibitors (NRTIs), and 0.3% (2/584) to protease inhibitors (PIs). Acquired drug resistance to any antiretroviral drug among PLWH on ART with viral load >1000 copies/mL was 88.7% (63/71). The prevalence of mutation for NNRTIs, NRTIs, and PIs were 93.7% (59/63), 82.5% (52/63), and 3.2% (2/63), respectively. CONCLUSIONS Pre-treatment and acquired drug resistance mutations were highly prevalent among PLWH in Tianjin; therefore, routine baseline genotypic resistance testing and adequate intervals of viral load surveillance are urgently needed for the long-term treatment success. Our findings provide important evidence for first- and second-line regimen drugs for PLWH, especially in China.

PLoS One 2021; 16:e0260670. [PMID: 34855860 PMCID: PMC8638862 DOI: 10.1371/journal.pone.0260670] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2021] [Accepted: 11/13/2021] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Human immunodeficiency virus type 1 (HIV-1) genetic diversity and pre-treatment drug resistance (PDR) are major barriers to successful antiretroviral therapy (ART). In China, sexual intercourse is the most frequent route of HIV-1 transmission. However, few studies have analyzed PDR and transmission networks in detail among individuals in China with acute HIV-1 infection and their sexual contacts. METHODS A cross-sectional study was conducted in Baoding City, Hebei Province, China from 2019-2020. CD4 T cell counts and viral loads were assessed and a HIV-1 genotypic PDR assay was developed in-house. Transmission networks were visualized using Cytoscape with a threshold genetic distance of 0.015 among HIV-1 subtypes. RESULTS From 139 newly diagnosed and drug-naïve individuals with HIV-1, 132 pol gene sequences were obtained and revealed eight HIV-1 subtypes. Circulating recombinant form (CRF)01_AE was the most frequent subtype (53.0%, 70/132) followed by CRF07_BC (26.5%, 35/132), B (13.6%, 18/132), unique recombinant forms (2.3%, 3/132), CRF55_01B (1.5%, 2/132), CRF103_01B (1.5%, 2/132), CRF65_cpx (0.8%, 1/132), and C (0.8%, 1/132). A total of 47 pol gene sequences were used to generate 10 molecular transmission networks. The overall prevalence of PDR was 7.6% and that of PDR to non-nucleotide reverse transcriptase inhibitors was 6.1%. Of three transmission networks for PDR, two were closely associated with Beijing and Tianjin, while another was restricted to sequences determined in this study. CONCLUSIONS These results demonstrate that during acute HIV-1 infection, PDR is transmitted in dynamic networks. This suggests that early detection, diagnosis, surveillance, and treatment are critical to effectively control HIV-1 spread.

Survey of pretreatment HIV drug resistance and the genetic transmission networks among HIV-positive individuals in southwestern China, 2014-2020. BMC Infect Dis 2021; 21:1153. [PMID: 34772365 PMCID: PMC8590229 DOI: 10.1186/s12879-021-06847-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Accepted: 11/03/2021] [Indexed: 11/10/2022] Open
Abstract
Background Pretreatment drug resistance (PDR) can limit the effectiveness of HIV antiretroviral therapy (ART). The aim of this study was to assess the prevalence of PDR among HIV-positive individuals that initiated antiretroviral therapy in 2014–2020 in southwestern China. Methods Consecutive cross-sectional surveys were conducted in Qinzhou, Guangxi. We obtained blood samples from individuals who were newly diagnosed with HIV in 2014–2020. PDR and genetic networks analyses were performed by HIV-1 pol sequences using the Stanford HIV-database algorithm and HIV-TRACE, respectively. Univariate and multivariate logistic regression models were used to explore the potential factors associated with PDR. Results In total, 3236 eligible HIV-positive individuals were included. The overall prevalence of PDR was 6.0% (194/3236). The PDR frequency to NNRTI (3.3%) was much higher than that of NRTI (1.7%, p < 0.001) and PI (1.2%, p < 0.001). A multivariate logistic regression analysis revealed that PDR was significantly higher among individuals aged 18–29 (adjusted odds ratio (aOR): 1.79, 95% CI 1.28–2.50) or 30–49 (aOR: 2.82, 95% CI 1.73–4.82), and harboring CRF08_BC (aOR: 3.23, 95% CI 1.58–6.59). A total of 1429 (43.8%) sequences were linked forming transmission clusters ranging in size from 2 to 119 individuals. Twenty-two individuals in 10 clusters had the same drug resistant mutations (DRMs), mostly to NNRTIs (50%, 5/10). Conclusions The overall prevalence of PDR was medium, numerous cases of the same DRMs among genetically linked individuals in networks further illustrated the importance of surveillance studies for mitigating PDR.

Abstract
Guangzhou city is the political, economic, and cultural center of the Guangdong Province, China. The molecular epidemiological characteristics of HIV-1 in Guangzhou are not widely known. The aim of this study was to explore the characteristics of HIV-1 genotypes among treatment naïve HIV/AIDS patients living in Guangzhou. HIV-1 RNA was extracted from serum specimens. The partial pol gene of the HIV-1 genome was amplified and sequenced. The genotypes were screened using the subtyping tool COMET and further confirmed by phylogenetic analysis, with the exception of the URFs that were analyzed by jpHMM and RIP. The distributions of HIV genotypes in different risk populations were analyzed. Subsequently, pol sequences were used to construct transmission networks and analyze drug resistance. Twelve HIV-1 genotypes including 3 subtypes and 9 CRFs, with several URFs were identified from 1388 HIV-1 sequences, which were derived from 1490 patients. The main genotypes circulating in Guangzhou were CRF07_BC (38.3%), CRF01_AE (32.3%), and CRF55_01B (10.7%). CRF01_AE was the secondary dominant strain and multiple lineages of CRF01_AE had been identified in Guangzhou. The 01B recombinant forms, including CRF55_01B, CRF59_01B and CRF68_01B, have circulated widely in Guangzhou. 42.22% (586/1388) of the study sequences fell into 143 transmission networks, and the three main clusters revealed that sequences from MSM and HET populations were intermixed. 5.40% (75/1388) of patients had pre-treatment drug resistance. The HIV-1 strains that were present in Guangzhou have demonstrated complex genotypes. Particular attention should be given on these genotypes for the further strategy of prevention and intervention of HIV transmission.
