Abstract
Co-circulation of multiple HIV-1 subtypes in the same high-risk groups leads to the on-going generation of various inter-subtype recombinants, including unique (URFs) and circulating (CRFs) recombinant forms, which brings a new challenge for the prevention and eradication of HIV/AIDS. Identification and prompt reporting of new CRFs will provide not only new insights into the understanding of genetic diversity and evolution of HIV-1, but also an early warning of potential prevalence of these variants. Currently, 140 HIV-1 CRFs have been described; however, their prevalence and clinical importance are less concerned. Apart from the mosaic genomic maps, less other valuable information, including the clinical and demographic data, genomic sequence characteristics, origin and evolutionary dynamics, as well as representative genomic fragments for determining the variants, are available for most of these CRFs. Accompanied with the growing increase of HIV-1 full-length genomic sequences, more and more CRFs will be identified in the near future due to the high recombination potential of HIV-1. Here, we discuss the prevalence and clinical importance of various HIV-1 CRFs and propose how to report and make sense of a new HIV-1 CRF.

[PMID: 37701839 PMCID: PMC10493081 DOI: 10.7717/peerj.16005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Accepted: 08/09/2023] [Indexed: 09/14/2023] Open
Abstract
Background Due to the deficiencies of vaccines and effective medicine, the human immunodeficiency virus (HIV) infection mechanism should be studied. The C19orf66 gene, one of the interferon-stimulated genes (ISGs), expresses broad-spectra anti-viral activity, including inhibiting HIV replication. Methods In this study, we collect 421 HIV-1 infected patients and 448 controls to genotype three SNPs in the C19orf66 gene. Then, the association between SNPs and biochemical indices/ HIV-1 subtypes are analyzed. Results Genotypes CC and CT of rs12611087 show statistically lower and higher frequencies in HIV-1 infected patients than in controls, respectively. Alleles C and T of rs12611087 play protective and risk roles in Yunnan HIV population, respectively. Biochemical indices analysis shows that HIV-1 infected persons carried genotype TT of rs77076061 express significantly lower CD3+/CD45+ ratio level and higher IBIL level. The epidemic subtypes of HIV-1 patients in this study are CRF 07_BC and CRF 08_BC. Moreover, subtype CRF 08_BC tends to infect persons with genotype CC of rs12611087. Conclusion The genetic polymorphisms of the C19orf66 gene are firstly studied and reported to associate with HIV-1 infection and biochemical indices of patients in Yunnan. Furthermore, subtype CRF 08_BC infection could be influenced by genotypes of SNP in the C19orf66 gene.

ARCHIVES OF SEXUAL BEHAVIOR 2023; 52:2683-2700. [PMID: 36607518 DOI: 10.1007/s10508-022-02503-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Revised: 12/01/2022] [Accepted: 12/02/2022] [Indexed: 06/17/2023]
Abstract
BACKGROUND Vietnamese female sex workers (VFSWs) cross the border into Kaiyuan City, Yunnan Province yearly. However, very little is known about both the health and psychological issues VFSWs experience. The objectives of this study were to explore the dominant discourses that emerged from the VFSWs' talk. The interviews occurred between May 2018 and June 2018 with 20 VFSWs who worked in Kaiyuan City, China. The English translated transcripts were analyzed using an eclectic feminist method of discourse analysis. Two discourses emerged. First, "Agency when working in Karaoke Bars and other Indoor Venues", and second, "Negative Impacts on Psychological Well-being and Other Problems from Migration." As for Discourse 1, the VFSWs positioned themselves as having agency over choosing their clientele as well as agency over what they were willing to negotiate with their clients to establish boundaries of their bodies. As for the Discourse 2, while there was a discourse of agency in their work there was also a contrasting, confounding discourse around the negative impact on psychological well-being and reports of stress as a migrant worker. Discourse 1 and Discourse 2 are confounding. When analyzed together, the discourses suggest that the impacts on psychological well-being may be more related to the migrant status of the women, supporting the notion of systemically influenced agency.

Using molecular network analysis to understand current HIV-1 transmission characteristics in an inland area of Yunnan, China. Epidemiol Infect 2023; 151:e124. [PMID: 37462024 PMCID: PMC10540185 DOI: 10.1017/s0950268823001140] [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: 02/27/2023] [Revised: 05/26/2023] [Accepted: 07/07/2023] [Indexed: 08/05/2023] Open
Abstract
HIV-1 molecular surveillance provides a new approach to explore transmission risks and targeted interventions. From January to June 2021, 663 newly reported HIV-1 cases were recruited in Zhaotong City, Yunnan Province, China. The distribution characteristics of HIV-1 subtypes and HIV-1 molecular network were analysed. Of 542 successfully subtyped samples, 12 HIV-1 strains were identified. The main strains were CRF08_BC (47.0%, 255/542), CRF01_AE (17.0%, 92/542), CRF07_BC (17.0%, 92/542), URFs (8.7%, 47/542), and CRF85_BC (6.5%, 35/542). CRF08_BC was commonly detected among Zhaotong natives, illiterates, and non-farmers and was mostly detected in Zhaoyang County. CRF01_AE was frequently detected among married and homosexual individuals and mostly detected in Weixin and Zhenxiong counties. Among the 516 pol sequences, 187 (36.2%) were clustered. Zhaotong natives, individuals aged ≥60 years, and illiterate individuals were more likely to be found in the network. Assortativity analysis showed that individuals were more likely to be genetically associated when stratified by age, education level, occupation, and reporting area. The genetic diversity of HIV-1 reflects the complexity of local HIV epidemics. Molecular network analyses revealed the subpopulations to focus on and the characteristics of the risk networks. The results will help optimise local prevention and control strategies.

BMC Infect Dis 2022; 22:741. [PMID: 36117159 PMCID: PMC9483295 DOI: 10.1186/s12879-022-07734-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2022] [Accepted: 09/05/2022] [Indexed: 11/10/2022] Open
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.

Discordance between HIV-1 Population in Plasma at Rebound after Structured Treatment Interruption and Archived Provirus Population in Peripheral Blood Mononuclear Cells. Microbiol Spectr 2022; 10:e0135322.

Abstract
Antiretroviral therapy (ART) can sustain the suppression of plasma viremia to below detection levels. Infected individuals undergoing a treatment interruption exhibit rapid viral rebound in plasma viremia which is fueled by cellular reservoirs such as CD4+ T cells, myeloid cells, and potentially uncharacterized cellular sources. Interrogating the populations of viruses found during analytical treatment interruption (ATI) can give insights into the biologically competent reservoirs that persist under effective ART as well as the nature of the cellular reservoirs that enable viral persistence under ART. We interrogated plasma viremia from four rare cases of individuals undergoing sequential ATIs. We performed next-generation sequencing (NGS) on cell-associated viral DNA and cell-free virus to understand the interrelationship between sequential ATIs as well as the relationship between viral genomes in circulating peripheral blood mononuclear cells (PBMCs) and RNA from rebound plasma. We observed population differences between viral populations recrudescing at sequential ATIs as well as divergence between viral sequences in plasma and those in PBMCs. This indicated that viruses in PBMCs were not a major source of post-ATI viremia and highlights the role of anatomic reservoirs in post-ATI viremia and viral persistence. IMPORTANCE Even with effective ART, HIV-1 persists at undetectable levels and rebounds in individuals who stop treatment. Cellular and anatomical reservoirs ignite viral rebound upon treatment interruption, remaining one of the key obstacles for HIV-1 cure. To further examine HIV-1 persistence, a better understanding of the distinct populations that fuel viral rebound is necessary to identify and target reservoirs and the eradication of HIV-1. This study investigates the populations of viruses found from proviral genomes from PBMCs and plasma at rebound from a unique cohort of individuals who underwent multiple rounds of treatment interruption. Using NGS, we characterized the subtypes of viral sequences and found divergence in viral populations between plasma and PBMCs at each rebound, suggesting that distinct viral populations appear at each treatment interruption.

Abstract
Objective HIV epidemiology in South-Central China is rarely reported. This study aims to characterize epidemiological and clinical features of HIV-infected patients in Hunan Province, located in South-Central China, for better management of HIV infections. Methods This retrospective study retrieved multi-center records of laboratory-confirmed HIV-infected patients in Hunan province. Information on HIV-associated mortality and antiretroviral therapies was also collected. Results Among 34,297 patients diagnosed with HIV infections from 2003 to 2018, 73.9% were males, 41.3% were older adults (≥50 years), and 71.2% were infected by heterosexual transmission. Despite a slow growth of new HIV infections in the overall population, annual percentages of HIV infections increased in older males (85.3% through heterosexual transmission) and young patients <30 years (39.9% through homosexual transmission). At baseline, serum levels of CD4+ T-cell counts were lower in older adults (191.0 cells/μl) than in young patients (294.6 cells/μl, p-value < 0.0001). A large proportion (47.2%, N = 16,165) of HIV-infected patients had advanced HIV disease (CD4+ T-cell counts < 200 cells/μl) from 2003 to 2018. All-cause mortality (57.0% due to AIDS-related illnesses) was reported among 4411 HIV-infected patients, including 2619 older adults. The 10-year survival rate was significantly lower in elderly males than in other patients (59.0 vs. 78.4%, p-value < 0.05). Conclusions Elderly males are prone to HIV infections with a high risk of HIV-associated fatality. Our findings support early prevention and critical care for elderly populations to control HIV infections.

Abstract
Background The China-Myanmar border area is considered a hot spot of active HIV-1 recombination in Southeast Asia. To better understand the characteristics of HIV-1 transmission in this area, a cross-sectional HIV-1 molecular epidemiological survey was conducted in Baoshan Prefecture of Yunnan Province. Methods In total, 708 newly reported HIV-1 cases in Baoshan Prefecture from 2019 to 2020 were included in this study. HIV-1 gag, pol and env genes were sequenced, and the spatial and demographic distributions of HIV-1 genotypes were analyzed. The characteristics of HIV-1 transmission were investigated using the HIV-1 molecular network method. Results In the 497 samples with genotyping results, 19 HIV-1 genotypes were found, with URFs being the predominant strains (30.2%, 150/497). The main circulating HIV-1 strains were mostly distributed in the northern area of Baoshan. URFs were more likely identified in Burmese individuals, intravenous drug users and those younger than 50 years old. CRF08_BC was more likely detected in farmers and those of Han ethnicity, CRF01_AE in the young and those of Han ethnicity, and CRF07_BC in the subpopulation with junior middle school education and higher. Moreover, CRF118_BC and CRF64_BC were more likely found in the subpopulation aged ≥40 years and ≥50 years, respectively. Among 480 individuals with pol sequence detection, 179 (37.3%) were grouped into 78 clusters, with Baoshan natives being more likely to be in the network. The proportion of the linked individuals showed significant differences when stratified by the regional origin, marital status, age and county of case reporting. In the molecular network, recent infections were more likely to occur among nonfarmers and individuals aged below 30 years. Conclusions HIV-1 genetics has become complex in Baoshan. HIV-1 molecular network analysis provided transmission characteristics in the local area, and these findings provided information to prioritize transmission-reduction interventions.

Abstract
New human immunodeficiency virus (HIV)-1 circulating recombinant forms (CRFs) have recently emerged and disseminated rapidly in China; in total 38 CRFs have been identified thus far. Yunnan province shares its border with Myanmar, and is regarded as a "hotspot" for the occurrence of new HIV-1 recombinations; more than half of novel CRFs reported in China have been first documented in Yunnan province. In the present study, based on the information available on four existing near-full-length genome (NFLG) sequences, combined with data on four other closely related sequences obtained via Basic Local Alignment Search Tool (BLAST) analysis, NFLG/subregion phylogenetic, bootscanning, and time to the most recent common ancestor (TMRCA) analyses were performed. Phylogenetic analysis revealed that the eight strains demonstrated the formation of a distinct monophyletic branch with a bootstrap value of 100%. Strains in this branch were distantly related to all known HIV-1 CRFs; it was temporarily named CRF111_01C. Bootscanning analysis revealed that CRF111_01C consisted of a CRF01_AE backbone and four inserted subtype C segments. Remarkably, CRF111_01C shared six mosaic fragment identities with the previously identified CRF100_01C. Furthermore, CRF111_01C may be deemed a potential second-generation CRF consisting of CRF100_01C and C. Coalescent Bayesian analyses revealed that the TMRCA of CRF111_01C was approximately the period 1999-2002. The emergence of such second-generation recombinants highlights that continuous molecular screening is necessary to carefully monitor the evolutionary dynamics of HIV-1 epidemics.

Curr HIV Res 2020; 17:240-257. [PMID: 31538898 DOI: 10.2174/1570162x17666190919115036] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2019] [Revised: 08/29/2019] [Accepted: 09/04/2019] [Indexed: 11/22/2022]
Abstract
BACKGROUND Since 1981, an increasing trend in HIV has been observed for transmission via injection drug users (IDUs), sexual transmission and mother-to-child transmission. The IDUs are blamed for early increases in HIV-positive cases in China. OBJECTIVE HIV genotypes of IDUs were comprehensively analysed to trace the source and relationships of the AIDS epidemic in China. METHODS Relevant databases written in English and Chinese were searched. Overall, 7,149 publications were identified in six databases. After screening 7,104 articles according to the inclusion and exclusion criteria, 45 studies consisting of 2,765 cases were finally identified. A meta-analysis was conducted using R MATLAB software, RevMan and SPSS. Subgroup analyses focused on time frame, region, and location of different genotypes of IDUs in China. RESULTS There were five dominant HIV-1 genotypes among the 2,765 IDU cases. The proportions of CRF07_BC, CRF01_AE, CRF08_BC, subtype B/B', and subtype C were 45.18% (95% CI: 33.55-57.08%), 16.00% (95% CI: 9.39-23.82%), 13.43% (95% CI: 7.32-20.84%), 3.58% (95% CI: 1.52-6.24%), and 0.90% (95% CI: 0.04-2.43%), respectively. HIV genotypes transmitted among IDUs in China are primarily CRF07-BC, followed by CRF01-AE and CRF08-BC. Across the different time frames and regions, CRF07_BC was the most prevalent HIV-1 genotype among IDUs, while CRF08_BC was the most prevalent genotype in the southwest region. CONCLUSION Our study reveals that CRF07-BC was the dominant prevalent strain among IDUs from 1991 to 2015 in China, while CRF08-BC was the dominant prevalent strain among IDUs in southwestern China. This systematic review and meta-analysis shows evidence of the comprehensive prevalence of different genotypes, data and characteristics of HIV among IDUs in China.

Abstract
HIV-1 drug resistance can compromise the effectiveness of antiretroviral therapy (ART). A survey of pretreatment HIV-1 drug resistance (PDR) was conducted in Lincang Prefecture of Yunnan Province. From 372 people living with HIV/AIDS initiating ART for the first time during 2017-2018, 322 pol sequences were obtained, of which 11 HIV-1 strain types were detected. CRF08_BC (70.2%, 226/322) was the predominant strain, followed by URF strains (10.6%, 34/322). Drug resistance mutations (DRMs) were detected among 34.2% (110/322) of the participants. E138A/G/K/R (14.3%, 46/322) and V179E/D/T (13.7%, 47/322) were the predominant DRMs. Specifically, E138 mutations commonly occurred in CRF08_BC (19.9%, 45/226). Among the DRMs detected, some independently conferred resistance, such as K65R (1.6%, 5/322), Y188C/F/L (0.9%, 3/322), K103N (0.6%, 2/322) and G190A (0.3%, 1/322), which conferred high-level resistance. The prevalence of PDR was 7.5% (95% CI: 4.6-10.3%) and the prevalence of non-nucleotide reverse transcriptase inhibitor (NNRTI) resistance was 5.0% (95% CI: 2.6-7.4%), which is below the threshold (⩾10%) of initiating a public health response. In conclusion, HIV-1 genetic diversity and an overall moderate level of PDR prevalence were found in western Yunnan. PDR surveillance should be continually performed to decide whether a public health response to NNRTI resistance should be initiated.

Abstract
There are well-known traditional risk factors for coronary artery disease (CAD). Among them, smoking is one of the most prominent and modifiable risk factors. This study aims to determine the magnitude of smoking as a risk factor for CAD in the Nepalese population. A hospital-based age- and sex-matched case-control study was carried out with a total of 612 respondents. Bivariate analysis showed that the risk of developing CAD in ex-smokers and current smokers was higher (odds ratio (OR): 1.81 (confidence interval (CI): 1.21-2.7) and OR: 5.2 (CI: 3.4-7.97)), with p-values less than 0.004 and <0.00001, respectively, compared to the risk in never smokers. From stratified socio-demographic, cardio-metabolic, behavioural and psychosocial risk factor analysis, smoking was found to be associated with CAD in almost all subgroups. In the subsequent multivariate analysis, adjustment for socio-demographic, cardio-metabolic and psychosocial risk factors showed a steady increase in risk. However, further adjustment for behavioural risk factors (alcohol use and physical activity) showed that the risk was attenuated by 59% in current smokers. After adjusting for the covariates, current smokers and ex-smokers had an increased risk of CAD (OR: 6.64, 95% CI: 3.64-12.12, p < 0.00001; OR: 1.89, 95% CI: 1.08-3.31, p < 0.012, respectively) compared with non-smokers. In conclusion, smoking was found to increase the risk of CAD in the Nepalese population.

Abstract
Background Guangdong Province is one of the most developed and populous provinces in southern China, with frequent foreign exchanges and large transient population. The annual number of cases of HIV/AIDS reported in Guangdong has been higher than most of provinces in China for several successive years. HIV infection by heterosexual transmission occurs across the province, with transmission among men who have sex with men occurring mainly in larger urban centers. There is a lack of widespread and representative data on the distribution of HIV subtypes in Guangdong. This study aimed to thoroughly investigate and estimate the prevalence and distribution of HIV-1 subtypes using a city-based sampling strategy to better understand the characteristics of HIV transmission in Guangdong. Methods Archived plasma samples (n = 1205) from individuals diagnosed as HIV-1 infection in 2013 were selected randomly from all 21 cities in Guangdong Province. Genotypes were determined using env and/or gag sequences using phylogenetic analysis. The distributions of HIV genotypes in different risk groups and different cities were analyzed. Results A total of 15 genotypes, including six discordant genotypes, were identified. The four main HIV-1 subtypes in Guangdong were CRF01_AE (43.2%), CRF07_BC (26.3%), CRF55_01B (8.5%), and CRF08_BC (8.4%). CRF01_AE was the predominant subtype in all risk populations. The high mobility of people shaped the complexity of the HIV genotypes, while the switch of risk factors affected the distribution and future trend of HIV-1 genotypes in Guangdong. Another epicenter located in the western region in addition to the known epicenter cities in the Pearl River Delta region of Guangdong may exist. Conclusions Our study provides a comprehensive molecular epidemiologic dataset to understand the diversity and distribution of HIV genotypes in Guangdong, as well as to clarify the unique region- and risk group-specific transmission dynamics. The results provide critical and insightful information for more effective intervention strategies to limit HIV transmission in the future.

Abstract
The cross border movement of populations would potentially increase the transmission and spread of various diseases including HIV/AIDS, which needed strict surveillance. In the current study, a total of 2,961,530 specimens were collected between 2012 and 2016 from the entry-exit populations at frontier ports of China for epidemiology and molecular epidemiology study. Results showed that HIV-1 prevalence rate among these populations was significantly higher than that of other general populations in China (p < .001). Epidemiological investigation indicated that most of the HIV-1 infected participants were male and young general population, in contrast to intravenous drug users as revealed by previous studies. There were significantly more female, Chinese, and migrant labors in southeastern ports than in northwestern ports (p < .05). Molecular epidemiology study revealed that three subtypes C/BC, CRF01_AE and B dominated, with the emerging of novel unique recombinant forms and drug-resistant viruses among this population. Overall, the results suggests and calls for the shift of HIV-1 prevention projects' focus and the continuous monitoring of HIV-1 molecular epidemiology among entry-exit populations. These findings are useful for the generation of evidence-based biomedical and behavioral prevention programs to HIV/AIDS.

Abstract
The discovery of an HIV-1 cure remains a medical challenge because the virus rebounds quickly after the cessation of combination antiretroviral therapy (cART). Here, we investigate the potential of an engineered tandem bispecific broadly neutralizing antibody (bs-bnAb) as an innovative product for HIV-1 prophylactic and therapeutic interventions. We discovered that by preserving 2 single-chain variable fragment (scFv) binding domains of each parental bnAb, a single gene-encoded tandem bs-bnAb, BiIA-SG, displayed substantially improved breadth and potency. BiIA-SG neutralized all 124 HIV-1-pseudotyped viruses tested, including global subtypes/recombinant forms, transmitted/founder viruses, variants not susceptible to parental bnAbs and to many other bnAbs with an average IC50 value of 0.073 μg/ml (range < 0.001-1.03 μg/ml). In humanized mice, an injection of BiIA-SG conferred sterile protection when administered prior to challenges with diverse live HIV-1 stains. Moreover, whereas BiIA-SG delayed viral rebound in a short-term therapeutic setting when combined with cART, a single injection of adeno-associated virus-transferred (AAV-transferred) BiIA-SG gene resulted dose-dependently in prolonged in vivo expression of BiIA-SG, which was associated with complete viremia control and subsequent elimination of infected cells in humanized mice. These results warrant the clinical development of BiIA-SG as a promising bs-bnAb-based biomedical intervention for the prevention and treatment of HIV-1 infection.

Abstract
Multiple human immunodeficiency virus (HIV)-1 genotypes in China were first discovered in Yunnan Province before disseminating throughout the country. As the HIV-1 epidemic continues to expand in Yunnan, genetic characteristics and transmitted drug resistance (TDR) should be further investigated among the recently infected population. Among 2828 HIV-positive samples newly reported in the first quarter of 2014, 347 were identified as recent infections with BED-captured enzyme immunoassay (CEIA). Of them, 291 were successfully genotyped and identified as circulating recombinant form (CRF)08_BC (47.4%), unique recombinant forms (URFs) (18.2%), CRF01_AE (15.8%), CRF07_BC (14.4%), subtype C (2.7%), CRF55_01B (0.7%), subtype B (0.3%) and CRF64_BC (0.3%). CRF08_BC and CRF01_AE were the predominant genotypes among heterosexual and homosexual infections, respectively. CRF08_BC, URFs, CRF01_AE and CRF07_BC expanded with higher prevalence in central and eastern Yunnan. The recent common ancestor of CRF01_AE, CRF07_BC and CRF08_BC dated back to 1983.1, 1992.1 and 1989.5, respectively. The effective population sizes (EPS) for CRF01_AE and CRF07_BC increased exponentially during 1991-1999 and 1994-1999, respectively. The EPS for CRF08_BC underwent two exponential growth phases in 1994-1998 and 2001-2002. Lastly, TDR-associated mutations were identified in 1.8% of individuals. These findings not only enhance our understanding of HIV-1 evolution in Yunnan but also have implications for vaccine design and patient management strategies.

Abstract
A rapidly increasing number of HIV-1 infections have been identified among men who have sex with men (MSM) in Fujian province of China since 2010. We aimed to investigate the causative factors underlying this surging epidemic. Using immunoassays for HIV-1 diagnosis and phylogenetic analysis for viral genotyping, we found that the number of MSM infections doubled from 171 in 2011 to 340 in 2013 with a significantly increased prevalent rate from 4.1% to 5.2%. Majority of these increased infections took place in Fuzhou, Xiamen, and Quanzhou, three large cities in Fujian, mainly among youth, unemployed, business, and well-educated MSMs. Phylogenetic analysis revealed three major HIV-1 genotypes including CRF01_AE, CRF07_BC, and B/B' yet the surging MSM infections were primarily associated with the rapid sexual spread of CRF07_BC in addition to CRF01_AE. In particular, there was a significant proportional expansion of CRF07_BC infections among recently infected MSMs from 19% in 2012 to 41.9% in 2013. This increase was accompanied by emergence of complex patterns of viral recombination including multiple hybrid variants derived from CRF01_AE and CRF07_BC. Full-genome analysis indicated that CRF07_BC in Fujian was likely originated from similar strains previously found among IDUs in Yunnan province but with unique recombination break points. Our findings indicated that HIV-1 CRF07_BC has adapted for rapid sexual transmission, resulting in the surging HIV-1 epidemic and the emergence of new recombinant strains among MSMs in Fujian. Our findings have implications to vaccine and passive immunization trials in Fujian with emphasis on the induction of cross-subtype protective immunity.

Abstract
In this study, a novel CRF01_AE/07_BC HIV-1 recombinant form, with five breakpoints in the pol, vpr, env, and nef gene regions, was identified from a voluntary blood donor in North China. Our study showed that this HIV-1 recombinant form might be a second-generation recombinant form from two predominant strains in the men who have sex with men (MSM) population, with the CRF07_BC fragments belonging to a CRF07_BC lineage specific to Chinese MSM and the CRF01_AE fragments belonging to the CRF01_AE lineage 5 common among MSM in northern China. Our findings supported the high-risk blood donation behaviors of MSM, implied the increasing complexity of the HIV-1 epidemic among the Chinese MSM population, and called more attention to the effectiveness of the screening test for the growing number of new HIV-1 recombinant forms.

Abstract
The Yunnan province in China has a high incidence of human immunodeficiency virus-1 (HIV-1) infection. Zhaotong City is located in the Yunnan province, a neglected 'important region'. In this study, we evaluated the unique molecular epidemiological characteristics of HIV-1 infection in Zhaotong City. We collected 305 serum samples from HIV-infected patients in Zhaotong City between May 2015 and April 2016. A total of 122 samples were selected for HIV-1 gag-pol gene amplification, of which 88 were successfully amplified and sequenced for phylogenetic and phylogeographic analysis. Circulating recombinant forms 07_BC (CRF07_BC, 23 cases, 26.14 %) and CRF08_BC (49 cases, 55.68 %) were the predominant subtypes; the high proportions of these two subtypes differed from those elsewhere in the Yunnan province. The other subtypes were CRF01_AE (11 cases, 12.5 %), B (one case, 1.14 %) and unique recombinant forms (four cases, 4.55 %). Phylogeographic analysis of the CRF07_BC and CRF08_BC subtype strains revealed that Zhaotong was one of the regions in which CRF07_BC and CRF08_BC entered initially. The CRF08_BC strain originated from this region closer to the 'root' position of the phylogenetic tree. Thus, Zhaotong City may have been an important channel in the transmission route of HIV-1 from Yunnan to other parts of the country. Based on this unique distribution of HIV-1 subtypes in Zhaotong City, the epidemic outbreak in this area may have played an important role in the spread of CRF07_BC and CRF08_BC subtypes.

Abstract
In China, CRF01_AE and CRF07_BC are the most circulating strains of HIV-1, more and more second-generation recombinant forms have been isolated around the two strains. The same situation happened in Beijing in recent years. In our study, we have isolated a new second-generation recombinant form of HIV-1 from a male patient who was infected by homosexual behavior. Polygenetic analysis revealed that the sequence includes five CRF01_AE fragments and four CRF07_BC fragments. CRF01_AE is the skeleton of the recombinant which was inserted with four CRF07_BC fragments. The emergency of such second-generation recombinant forms manifests the diversity of the HIV-1 epidemic. Consequently, further investigation of molecular epidemiology is needed to track the genetic evolution of HIV-1.

Abstract
Background: Heterosexual transmission (HST) has become the current predominant transmission pathways of the HIV-1 epidemic in China. The aim of this study was to explore the geographic and dynamic change of HIV-1 subtypes through HST in China from published studies. Methods: Several electronic databases were searched to identify the studies, and the overall prevalence of HIV-1 subtypes was estimated by a meta-analysis method. Subgroup analysis was conducted by study region and time period. Publication bias was evaluated using Egger's test. The χ² test was used to evaluate the proportion differences among subgroups. Sensitivity analysis was carried out to assess the stability of the overall prevalence estimates. Results: 42 studies were included in our final analysis. The overall prevalence of CRF01_AE was 46.34% (95% CI: 40.56-52.17%), CRF07_BC was 19.16% (95% CI: 15.02-23.66%), B/B' was 13.25% (95% CI: 9.68-17.25%), CRF08_BC was 10.61% (95% CI: 7.08-14.70%), and C was 4.29% (95% CI: 1.85-7.48%). In subgroup analysis, the prevalence of CRF01_AE and CRF07_BC increased, while the prevalence of B/B' decreased over time, whereby the prevalence of CRF07_BC and CRF08_BC have exceeded that of B/B' since 2010. A significant higher prevalence of CRF01_AE was found in the South provinces, CRF07_BC in East provinces, CRF08_BC and C in Southwest provinces, and B/B' in North provinces. Conclusions: The HIV-1 prevalent strains have evolved into complicated and diverse subtypes, and the proportion of HIV-1 subtypes through HST has changed constantly in different regions and periods in China. This highlights the urgent need to vigorously strengthen the prevention and control of the HIV-1 epidemic.

Abstract
Increasing second-generation recombinant forms (CRF01_AE/07_BC) have been detected in China recently. Here, we isolated a novel CRF01_AE/07_BC second-generation recombinant form in HIV-1-positive Nei Monggoi's heterosexuals with one CRF07_BC inserted into the CRF01_AE backbone. Polygenetic analyses showed that the CRF01_AE region was grouped with the previously reported cluster 5 lineage, which spreads among the sexual population in north of China, inferring that this recombinant event occurred through heterosexual contact in the north of China possibly. The growing emergence of recombinant forms means coexistence of multiple strains and complexity of the HIV-1 epidemic, which reminds us of the urgent necessity to focus the HIV surveillance among the high-risk populations nationwide in China, particularly to enhance preventive measures in HIV-1 low-prevalence areas.

Abstract
In this research, we reported a new second generation recombinant form (GXDY460B) between circulating recombinant form (CRF)01_AE and CRF07_BC in a seroconversion couple who obtained the virus from her husband by heterosexual behavior. The analysis result of the near full-length genomic characterization showed that the genome comprises at least 12 interlaced segments, including six CRF07_BC and six CRF01_AE segments, with CRF07_BC as the main framework. Cocirculation of multiple virus subtypes and multiple infection routes have existed for a long time in Guangxi, but the recombinant strain was rarely reported among heterosexual transmission population because of its lower crowd confounding degree than men who have sex with men and injecting drug user population. It is the first time that the unique recombinant form (URF) between CRF01_AE and CRF07_BC was identified among heterosexual transmission in Guangxi. The emergence of the novel recombinant helps to understand the pattern of the URF virus.

Abstract
Yunnan seems to be a "hot spot" region of HIV-1 recombination. CRF01_AE and subtype CRF08_BC are two main HIV-1 clades circulating in Yunnan. We report here a novel HIV-1 second-generation recombinant form originated from CRF01_AE and CRF08_BC. The strain (12YN10551) was isolated from a HIV-positive male infected through heterosexual contact in Dali prefecture of Yunnan province, China. This is the first report of HIV-1 near full-length genomic sequence in Dali. Recombinant analysis shows that 12YN10551 was composed of two well-established circulating recombinant forms (CRF01_AE and CRF08_BC). Two CRF01_AE recombinant fragments were inserted into the CRF08_BC backbone genome in the pol/vif/vpr/tat/rev and nef gene regions, respectively. The discovery and characterization of this new recombinant indicate that intersubtype recombination is continuously generating new forms of HIV-1. More work is needed to better monitor the genetic diversity of HIV-1 in this region.

Abstract
We report a novel HIV circulating recombinant form (CRF78_cpx) composed mainly of CRF01_AE with inserts from subtypes B and C identified from three epidemiologically unlinked individuals in Yunnan province, China. Two of the subjects are heterosexual men and one is a male intravenous drug user. Sequencing and analyzing the near-full-length genome of these three isolates (YNTC88, YNTC19, and YNTC35) revealed identical recombination breakpoints in all three viruses, but considerable genetic diversity between them, across the genomes, indicating that this is not a newly created CRF, only newly detected. CRF78_cpx differs from previously documented CRF01-AE/B'/C forms in its distinct backbone, inserted fragment size, and breakpoints, and is not related to other described recombinants in the region such as CRF07_BC or CRF65_cpx (also composed of CRF01_AE, B', and C). Our present findings further enrich the diversity of the prevalent HIV-1 CRFs in Yunnan, which is considered as an epicenter of HIV-1 infections in China.

Abstract
Recombination contributes substantially to the genetic diversity of HIV-1. Recently, many kinds of circulating recombinant forms (CRFs) and unique recombinant forms (URFs) were identified in China, especially in areas with multiple subtypes of HIV-1 circulating. Yunnan, which borders the "Golden triangle" region of South China, is an epicenter of HIV-1 infections in China. Multiple subtypes, including subtypes B, CRF01_AE, CRF07_BC, and CRF08_BC, were found epidemic in the area. Many URFs composed of subtypes B and C genomes were identified in Yunnan; however, CRF01_AE/B recombinant form is relatively rare. In this study, we identified a novel recombinant form of CRF01_AE/B, which was isolated from a heterosexual transmitted individual. The genomic structure of the strain is distinctly different from any previously reported URFs. Three CRF01_AE segments were inserted into the subtype B backbone genome. In the past few years, many kinds of URFs and CRFs have emerged and spread quickly in China, which implies that coinfection or super infection of more than one HIV-1 subtype might be common in China, especially in Yunnan. Therefore, more work is needed to monitor the appearance of URFs and survey the epidemiologic significance of the new recombination.

Rapid and Simultaneous Detection of Major Drug Resistance Mutations in Reverse Transcriptase Gene for HIV-1 CRF01_AE, CRF07_BC and Subtype B in China Using Sequenom MassARRAY® System. PLoS One 2016; 11:e0153641. [PMID: 27092551 PMCID: PMC4836728 DOI: 10.1371/journal.pone.0153641] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2015] [Accepted: 04/01/2016] [Indexed: 01/10/2023] Open
Abstract
The development of a rapid, high-throughput and cost-effective HIV-1 drug resistance (HIV-DR) testing system is a challenge for areas consisting different HIV-1 strains. In this study, we established a broadly reactive multiplex assay that could simultaneously detect major drug resistance mutations at 8 loci, which are associated with resistance to commonly used nucleoside reverse transcriptase inhibitors (NRTIs) and Non-nucleoside reverse transcriptase inhibitors (NNRTIs), in specimens of HIV-1 CRF01_AE, CRF07_BC and subtype B, the three major circulating strains in China, using the matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) provided by Sequenom MassARRAY® system. To establish the assay, pol gene fragments were prepared from the plasma viral RNA of 159 patients by nested PCR and the presence of wild type and mutant alleles at the 8 loci were analyzed by MALDI-TOF MS. In terms of loci, the detection rate of the alleles was greater than 97% for M41L, K65R, M184V and G190A, 91.2% for K101E/Q/P, 91.2% for T215F/Y, 89.9% for K103N/S and 80.5% for L210W. In terms of individuals, 80% of the alleles were detected in 95.4% CRF01_AE patients, 100% CRF07_BC patients and 83.3% subtype B patients. Importantly, the MALDI-TOF MS results were concordant to the drug resistance profiles of patients obtained from conventional sequencing analysis after excluded the failed detections. Using plasmid templates, the assay was estimated to be sensitive to detect drug resistant variants at level about 20% of the circulating viral population. The capability of this assay to detect mixed viral populations was further verified by two different patient specimens. In conclusion, this study evaluated the use of Sequenom MassARRAY® system for high-throughput detection of HIV-DR mutations towards the commonly used reverse transcriptase inhibitors in China.

Abstract
Background Here, we aimed to gain a comprehensive picture of the HIV-1 diversity in the northeast and southeast part of Brazil. To this end, a high-throughput sequencing-by-synthesis protocol and instrument were used to characterize the near full length (NFLG) and partial HIV-1 proviral genome in 259 HIV-1 infected blood donors at four major blood centers in Brazil: Pro-Sangue foundation (São Paulo state (SP), n 51), Hemominas foundation (Minas Gerais state (MG), n 41), Hemope foundation (Recife state (PE), n 96) and Hemorio blood bank (Rio de Janeiro (RJ), n 70). Materials and Methods A total of 259 blood samples were obtained from 195 donors with long-standing infections and 64 donors with a lack of stage information. DNA was extracted from the peripheral blood mononuclear cells (PBMCs) to amplify the HIV-1 NFLGs from five overlapping fragments. The amplicons were molecularly bar-coded, pooled, and sequenced by Illumina paired-end protocol. Results Of the 259 samples studied, 208 (80%) NFLGs and 49 (18.8%) partial fragments were de novo assembled into contiguous sequences and successfully subtyped. Of these 257 samples, 183 (71.2%) were pure subtypes consisting of clade B (n = 167, 65%), C (n = 10, 3.9%), F1 (n = 4, 1.5%), and D (n = 2, 0.7%). Recombinant viruses were detected in 74 (28.8%) samples and consist of unique BF1 (n = 41, 15.9%), BC (n = 7, 2.7%), BCF1 (n = 4, 1.5%), CF1 and CDK (n = 1, 0.4%, each), CRF70_BF1 (n = 4, 1.5%), CRF71_BF1 (n = 12, 4.7%), and CRF72_BF1 (n = 4, 1.5%). Evidence of dual infection was detected in four patients coinfected with the same subtype (n = 3) and distinct subtype (n = 1). Conclusion Based on this work, subtype B appears to be the prevalent subtype followed by a high proportion of intersubtype recombinants that appeared to be arising continually in this country. Our study represents the largest analysis of the viral NFLG ever undertaken worldwide and provides insights into the understanding the genesis of the HIV-1 epidemic in this particular area of South America and informs vaccine design and clinical trials.

Abstract
Sexual transmission has become the primary route of HIV transmission in China. Therefore, a comprehensive overview of HIV-1 subtype distribution is necessary for the prevention and control of the HIV epidemic. The present study aimed to provide a comprehensive prevalence estimate of different HIV-1 subtypes in sexual transmission in China. We conducted a systematic literature review for studies of HIV-1 subtypes in English and Chinese through several databases. Eligible articles were screened and selected by two authors independently. Random-effects model were applied to calculate the pooled prevalence of different HIV-1 subtypes, and subgroup analyses examined prevalence estimates across time, locations, and populations. A total of 130 eligible studies were identified, including 18 752 successfully genotyped samples. The pooled prevalence of CRF01_AE, subtype B, CRF07_BC, CRF08_BC, and subtype C were 44·54% (95% CI 40·81-48·30), 18·31% (95% CI 14·71-22·17), 16·45% (95% CI 13·82-19·25), 2·55% (95% CI 1·56-3·73), 0·37% (95% CI 0·11-0·72), respectively. The prevalence of subtype B in sexual transmission decreased, while the prevalence of CRF01_AE and CRF07_BC in sexual transmission, and CRF08_BC in heterosexual transmission increased. There is significant variation in HIV-1 subtype distribution between regions. The distribution of HIV-1 subtypes and circulating recombinant forms have changed significantly. The high genetic variability of HIV-1 poses a significant challenge for disease control and surveillance in China.

Abstract
An overall decrease of HIV prevalence is now observed in several key Asian countries due to effective prevention programs. The decrease in HIV prevalence and incidence may further improve with the scale-up of combination prevention interventions. The implementation of future prevention trials then faces important challenges. The opportunity to identify heterosexual populations at high risk such as female sex workers may rapidly wane. With unabating HIV epidemics among men who have sex with men (MSM) and transgender (TG) populations, an effective vaccine would likely be the only option to turn the epidemic. It is more likely that efficacy trials will occur among MSM and TG because their higher HIV incidence permits smaller and less costly trials. The constantly evolving patterns of HIV-1 diversity in the region suggest close monitoring of the molecular HIV epidemic in potential target populations for HIV vaccine efficacy trials. CRF01_AE remains predominant in southeast Asian countries and MSM populations in China. This relatively steady pattern is conducive to regional efficacy trials, and as efficacy warrants, to regional licensure. While vaccines inducing nonneutralizing antibodies have promise against HIV acquisition, vaccines designed to induce broadly neutralizing antibodies and cell-mediated immune responses of greater breadth and depth in the mucosal compartments should be considered for testing in MSM and TG. The rationale and design of efficacy trials of combination prevention modalities such as HIV vaccine and preexposure prophylaxis (PrEP) remain hypothetical, require high adherence to PrEP, are more costly, and present new regulatory challenges. The prioritization of prevention interventions should be driven by the HIV epidemic and decided by the country-specific health and regulatory authorities. Modeling the impact and cost-benefit may help this decision process.

Abstract
Unlike most areas of China, HIV transmission via men who have sex with men (MSM) is increasing rapidly, and has become the main route of HIV transmission in Harbin city. The purpose of the current study was to elaborate the molecular epidemiologic characteristics of the new HIV epidemic. Eighty-one HIV-1 gag gene sequences (HXB2:806-1861) from local HIV infections were isolated; CRF01_AE predominated among HIV infections (71.6%), followed by subtype B (16.5%), CRF07_BC (6.2%), and unique recombinant strains (URFs; 6.2%). URFs were most often identified in the MSM population, which consisted of a recombination of CRF01_AE with subtype B or CRF07_BC. Six clusters were formed in this analysis; clusters I and II mainly circulated in southwest China. Clusters III and IV mainly circulated in southwest, southeast, and central China. Clusters V and VI mainly circulated in north and northeast China. Clusters III and IV may facilitate the transmission of the CRF01_AE strain from the southwest to the north and northeast regions of China. HIV subtypes are becoming diverse with the persistent epidemic in this geographic region. In brief, our results indicate that the molecular epidemiology of HIV is trending to be more complex. Thus, timely molecular epidemiologic supervision of HIV is necessary, especially for the MSM population.

Abstract
To investigate the molecular subtypes of prevalent HIV-1 strains and characterize the genetics of dominant strains among men who have sex with men. Molecular epidemiology surveys in this study concentrated on the prevalent HIV-1 strains in Liaoning province by year. 229 adult patients infected with HIV-1 and part of a high-risk group of men who have sex with men were recruited. Reverse transcription and nested PCR amplification were performed. Sequencing reactions were conducted and edited, followed by codon-based alignment. NJ phylogenetic tree analyses detected two distinct CRF01_AE phylogenetic clusters, designated clusters 1 and 2. Clusters 1 and 2 accounted for 12.8% and 84.2% of sequences in the pol gene and 17.6% and 73.1% of sequences in the env gene, respectively. Another six samples were distributed on other phylogenetic clusters. Cluster 1 increased significantly from 5.6% to 20.0%, but cluster 2 decreased from 87.5% to 80.0%. Genetic distance analysis indicated that CRF01_AE cluster 1 in Liaoning was homologous to epidemic CRF01_AE strains, but CRF01_AE cluster 2 was different from other scattered strains. Additionally, significant differences were found in tetra-peptide motifs at the tip of V3 loop between cluster 1 and 2; however, differences in coreceptor usage were not detected. This study shows that subtype CRF01_AE strain may be the most prevalent epidemic strain in the men who have sex with men. Genetic characteristics of the subtype CRF01_AE cluster strain in Liaoning showed homology to the prevalent strains of men who have sex with men in other parts of China.

Abstract
CRF01_AE, which has led a new epidemic in many provinces in China and has displayed complex characteristics, has now evolved into multiple clusters in China. Some clusters often circulate in specific regions or among specific risk populations in China. To better determine the characteristics of CRF01_AE circulating in Anhui Province, we analyzed CRF01_AE based on gag and pol sequences. Our results showed that CRF01_AE circulating in Anhui Province was clearly divided into three clusters. Cluster 1 covered 90% of the sequences in all CRF01_AE. Among Cluster 1, the sequences from men who have sex with men (MSM) and heterosexuals were interwoven. It is suggested that MSM may play a bridge role in transmitting HIV-1 among the different risk groups.

Abstract
We report here two novel HIV-1 recombinant forms (CRF01_AE/B) isolated from two HIV-positive male subjects infected through homosexual contact in Beijing, China. Recombination contributes substantially to the genetic diversity of HIV-1, and is likely to occur in populations in which multiple subtypes circulate. Molecular epidemiological studies showed that subtype B, CRF01_AE, and CRF07_BC are currently cocirculating in parallel among men who have sex with men (MSM) in China, providing the opportunity for the emergence of new recombinants. Phylogenetic analysis of near full-length genome (NFLG) sequences showed that the unique recombinant forms (URFs) were composed of gene regions from CRF01_AE and subtype B. The CRF01_AE region of the recombinants clustered together with a previously described cluster 4 lineage of CRF01_AE. The B regions of both the recombinants clustered within the B strains. The two recombinants were quite similar with six breakpoints in common. These data highlight the importance of continuous surveillance of the dynamic change of HIV-1 subtypes and new recombinants among the MSM population.

Abstract
The Myanmar-China border appears to be the "hot spot" region for the occurrence of HIV-1 recombination. The majority of the previous analyses of HIV-1 recombination were based on partial genomic sequences, which obviously cannot reflect the reality of the genetic diversity of HIV-1 in this area well. Here, we present a near full-length characterization of a novel HIV-1 CRF01_AE/B/C recombinant isolated from a long-distance truck driver in Northern Myanmar. It is the first description of a near full-length genomic sequence in Myanmar since 2003, and might be one of the most complicated HIV-1 chimeras ever detected in Myanmar, containing four CRF01_AE, six B segments, and five C segments separated by 14 breakpoints throughout its genome. The discovery and characterization of this new CRF01_AE/B/C recombinant indicate that intersubtype recombination is ongoing in Myanmar, continuously generating new forms of HIV-1. More work based on near full-length sequence analyses is urgently needed to better understand the genetic diversity of HIV-1 in these regions.

Abstract
The most common antiretroviral treatment (ART) received by individuals infected with HIV-1 in China is the combination therapy, comprised of nucleoside reverse transcriptase inhibitors (NRTIs) and nonnucleoside reverse transcriptase inhibitors (NNRTIs). To assess the prevalence of HIV-1 drug resistance and subtypes in Honghe of Yunnan, China, patient plasmas from ART-failed individuals were collected from January 2010 to December 2012. Genotyping was conducted using an in-house assay on patient plasmas. A total of 254 pol sequences were obtained. The prevalence of drug resistance was 47.2% in ART-failed individuals. Of these drug-resistant individuals, 51.7% harbored HIV strains dually resistant to NRTIs and NNRTIs or protease inhibitors (PIs) (34.2% for NNRTIs and 14.2% for NRTIs). Mutations such as M184V, A62V, T69Ins, K103N, Y181C, and G190A were common among the ART-failed individuals. The frequencies of M184V, A62V, and K103N were 20.5%, 11.0%, and 23.6%, respectively. The most common subtypes in Honghe were CRF08_BC (68.50%) and CRF07_BC (12.20%). The subtypes were almost consistent in different time points for one individual. When receiving ART for 6-12 months, the frequency of HIV-1 drug-resistant variants ranked first. This study shows that the high prevalence of HIV drug resistance observed among the ART-failed individuals should be of increasing concern (monitoring of resistance mutations) in ART regions and facilitate developing novel strategies for prevention and control of HIV infection in China.

The sexually driven epidemic in youths in China's southwestern border region was caused by dynamic emerging multiple recombinant HIV-1 strains. Sci Rep 2015; 5:11323. [PMID: 26133091 PMCID: PMC4489098 DOI: 10.1038/srep11323] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2014] [Accepted: 05/01/2015] [Indexed: 11/25/2022] Open
Abstract
Dehong prefecture, Yunnan province on China’s southwestern border was the gateway of the country’s AIDS epidemic. Studies on HIV-1 molecular epidemiology will provide key information on virus transmission dynamics and help to inform HIV prevention strategies. HIV-1 infected youths (age 16–25 years) diagnosed in the continuous 3 months in 2009 to 2012 were enrolled. By means of phylogenetic and statistical analyses, It was showed that two thirds (133/205) of youths in Dehong, of which 74.1% were infected sexually, were infected by uncharacterized recombinant HIV-1 strains. Among them about 59.4% (79/131) were unique recombinant forms (URFs) and 40.6% (54/131) formed 11 transmission clusters, termed potential circulating recombinant forms (pCRFs). The emergence of recombinants was statistically significant related with people of low education, residents outside the capital city of Dehong and being Myanmar residents. It was the first report with ongoing HIV-1 recombinant strains in a sexually driven epidemic area in China. Great efforts should be put on reducing multiple risk exposures behavior in local young people, containing the spread of pCRFs to other regions, and preventing the URFs from evolving into future CRFs. Collaborative prevention across border is needed to better control the local AIDS epidemic.

Abstract
The aim of this study was to analyze the distribution of clusters and drug resistance of CRF01_AE among newly diagnosed, treatment-naïve HIV-infected teenagers and young adults in 3 major HIV-affected geographic regions of Guangxi Province, including the cities of Hezhou, Liuzhou, and Nanning. Samples were sequentially collected from newly diagnosed HIV-infected 16- to 25-year olds in these 3 regions from 2009 to 2013. The viral genome was extracted, and the partial pol gene was amplified and sequenced. Phylogenetic analyses were used to determine HIV-1 subtypes and CRF01_AE clusters. Transmitted drug resistance (TDR) mutations were identified using the 2009 WHO list of TDR mutations. A total of 216 sequences were obtained from CRF01_AE strains, which accounted for 83.1% of the 260 genotyped samples, of which 36 were from Hezhou, 147 from Liuzhou, and 33 in Nanning. Most (83.3%, 180/216) were from heterosexuals, followed by injection drug users (5.6%), homosexuals (4.2%), and unknown risk group (6.9%). Based on phylogenetic analyses by the maximum likelihood method, 5 distinct clusters (cluster 1-5) were identified with 213 (98.6%) sequences, whereas 3 (1.4%) sequences were ungrouped. In Hezhou, 88.9% (32/36) of CRF01_AE infections were caused by cluster 2, and 11.1% (4/36) were caused by cluster 1. In Liuzhou, 83.0% (122/147) of the CRF01_AE strains were found in cluster 1, 11.6% (17/147) from cluster 2, 1.4% (2/147) from cluster 3, 2.7% (4/147) from cluster 4, and 0.7% (1/147) from cluster 5. The distribution of CRF01_AE clusters was more even in Nanning than it was in the other 2 regions, with 18.2% (6/33) from cluster 1, 36.3% (12/33) from cluster 2, 9.1% (3/33) from cluster 3, 18.2% (6/33) from cluster 4, and 12.1% (4/33) from cluster 5. The most frequent TDR mutations were M46I (2) in the protease region and Y181C (2) from the reverse transcriptase fragment. Clusters 1 and 2 of CRF01_AE strains were prevalent in Liuzhou and Hezhou, respectively. However, multiple CRF01_AE clusters existed in Nanning. This can be partially explained by the high mobility of laborers in Nanning, the capital city of Guangxi. The prevalence of TDR was low.

Abstract
The increasing prevalence of HIV-1 among men having sex with men (MSM) calls for an investigation of HIV-1 prevalence and incidence in MSM by early diagnosis to assist with early preventive interventions in Hong Kong. The participants were recruited randomly from MSM communities within a one-year period. Rapid HIV Test (RHT) and real-time dried blood spot (DBS)-based quantitative polymerase chain reaction (DBS-qPCR) were used for the early diagnosis of 474 participants. Risk behavior analysis was performed by studying information obtained from the participants during the study period. The HIV-1 prevalence and incident rates in the studied MSM population were 4.01% (19/474) and 1.47% (7/474), respectively. Three infected participants were found at the acute phase of infection by DBS-qPCR. Only 46.4% (220/474) MSM were using condoms regularly for anal sex. HIV infection significantly correlated with unprotected receptive anal sex and syphilis infection. An increased number of infections was found among foreign MSM in Hong Kong. This study is the first to use DBS-qPCR to identify acutely infected individuals in a community setting and to provide both the prevalence and incident rates of HIV-1 infection among MSM in Hong Kong. The risk analysis provided evidence that behavior intervention strengthening is necessary to fight against the increasing HIV-1 epidemic among MSM in Hong Kong and surrounding regions in Asia.

Abstract
The aim of this study was to assess HIV-1 prevalence and the distribution of HIV-1 subtypes among travelers crossing the border at the HeKou land port. Between 2003 and 2012, 22,799 persons were randomly recruited from people entering China from Vietnam. In this crossing border population, a total of 161 (0.71%) travelers were determined as HIV-1-positive. From them, 140 HIV-1-positive serum samples were collected for RNA extraction and subsequent RT-nested PCR amplification of the group-specific antigen (gag)-RT with a length of 2.6 kb. The DNA sequences were analyzed to determine the HIV-1 subtypes/recombinants. We found that the circulating recombinant form 01_AE (CRF01_AE) was the most common HIV-1 subtype, accounting for 49.4% (41/83) of the subtyped 83 samples, followed by CRF08_BC (26.5%, 22/83) and CRF07_BC (7.2%, 6/83). Only 1 sample was classified as subtype C. Thirteen cases could not be clustered into any known subtypes or CRFs and presented as unique recombinant forms (URFs). Of them, 6 recombination patterns were identified. They had distinct structures consisting of fragments of subtypes B, C, CRF01_AE, CRF07_BC and CRF08_BC. Between 2003 and 2012, CRF01_AE and CRE08_BC were shown to be the most prevalent recombinant forms identified each year. But yearly change of each subtype is uncertain regular among in these travelers during the past decade. Understanding the distribution of HIV-1 subtypes/recombinants and how it changes across time among individuals entering China from Vietnam through this land port is crucial to establish strategies for the prevention of HIV cross-border transmission.

Abstract
BACKGROUND Distribution of HIV-1 subtypes, transmitted drug resistance (TDR)/drug resistance mutation (DRM), and their impact on response to combination antiretroviral therapy remain poorly understood in China. METHODS We analyzed data from our multicenter cohort study with 444 antiretroviral-naive participants recruited between 2008 and 2010. HIV-1 subtype and tropism were determined by V3 sequencing, and TDR/DRM was determined by Pol sequencing. Virologic and immunologic responses were monitored over 96 weeks of follow-up. The initial combination antiretroviral therapy regimen for all patients was nevirapine + lamivudine + zidovudine or stavudine. Analysis 1 included patients who finished 96 weeks of follow-up (n = 379), and analysis 2 included all 444 patients. RESULTS Subtype B/B' was associated with higher prevalence of TDR/DRM to nucleoside reverse transcriptase inhibitors and nonnucleoside reverse transcriptase inhibitors. Median time to HIV-1 suppression was 18 weeks in all 3 subtype groups. In Cox proportional models for viral suppression, neither viral tropism nor HIV-1 subtypes had any impact on viral suppression; however, subtypes CRF01_AE and C/CRF07_BC/CRF08_BC were associated with lower risk of virologic failure compared with subtype B/B', with adjusted hazard ratio of 0.11 (P = 0.032) and 0.06 (P = 0.036), respectively in analysis 1, 0.42 (P = 0.047) and 0.22 (P = 0.008), respectively in analysis 2. This association was attenuated by adding DRM profiles to multivariate regression models. Neither subtype nor HIV-1 tropism affected immunologic response. CONCLUSIONS HIV-1 subtype tended to be associated with virologic but not immunologic response; this effect could be ascribed to baseline DRM.

Abstract
CRF01_AE and subtype B are the two major HIV-1 clades circulating in China. Heterosexual transmission is the predominant route for the spread of HIV and heterosexuals often include men who have sex with men and intravenous drug users. Furthermore, many kinds of circulating recombinant forms (CRF) and unique recombinant forms (URF) between CRF01_AE and subtype B were recently identified in Southeast Asia. Therefore it is inevitable that the new recombinant of CRF01_AE/B will emerge among them. Here we identified a novel recombinant of CRF01_AE/B, isolated from heterosexuals, which has a distinctly different genome structure from other CRF01Bs and URFs reported before. The analysis of the near full-length sequence of JS2011001 shows that it is composed of at least five interlaced CRF01_AE and B segments. Recently, many kinds of URFs and CRFs began to prevail within a short period in China, which implies that a mix of HIV-1 infections is common in China and more attention should focus on it.

Abstract
The epidemic characteristics of human immunodeficiency virus type 1 (HIV-1) in Zhejiang Province have not been systematically identified. This study presented a dynamic analysis of HIV-1 subtype variation in Zhejiang from 2004 to 2008, based on the surveillance of molecular epidemiology or drug resistance. CRF01_AE was the major strain (43.5 %) spreading across the province, second by B/B' (17.9 %), CRF07_BC (17.1 %), and CRF08_BC (13.7 %). The strains were mainly transmitted by heterosexual contact. Novel recombinant strains and vertical transmission were occasionally reported. Floating population from other provinces accounted for a significant number of HIV-1 cases in Zhejiang. These data may provide us rational intervention strategy for further control of HIV dissemination.

Three amino acid residues in the envelope of human immunodeficiency virus type 1 CRF07_BC regulate viral neutralization susceptibility to the human monoclonal neutralizing antibody IgG1b12.

Abstract
The CD4 binding site (CD4bs) of envelope glycoprotein (Env) is an important conserved target for anti-human immunodeficiency virus type 1 (HIV-1) neutralizing antibodies. Neutralizing monoclonal antibodies IgG1 b12 (b12) could recognize conformational epitopes that overlap the CD4bs of Env. Different virus strains, even derived from the same individual, showed distinct neutralization susceptibility to b12. We examined the key amino acid residues affecting b12 neutralization susceptibility using single genome amplification and pseudovirus neutralization assay. Eleven amino acid residues were identified that affect the sensitivity of Env to b12. Through site-directed mutagenesis, an amino acid substitution at position 182 in the V2 region of Env was confirmed to play a key role in regulating the b12 neutralization susceptibility. The introduction of V182L to a resistant strain enhanced its sensitivity to b12 more than twofold. Correspondingly, the introduction of L182V to a sensitive strain reduced its sensitivity to b12 more than tenfold. Amino acid substitution at positions 267 and 346 could both enhance the sensitivity to b12 more than twofold. However, no additive effect was observed when the three site mutageneses were introduced into the same strain, and the sensitivity was equivalent to the single V182L mutation. CRF07_BC is a major circulating recombinant form of HIV-1 prevalent in China. Our data may provide important information for understanding the molecular mechanism regulating the neutralization susceptibility of CRF07_BC viruses to b12 and may be helpful for a vaccine design targeting the CD4bs epitopes.

Diverse forms of HIV-1 among Burmese long-distance truck drivers imply their contribution to HIV-1 cross-border transmission. BMC Infect Dis 2014; 14:463.

Abstract
BACKGROUND The China-Myanmar border is a particularly interesting region that has very high prevalence of and considerable diversity of HIV-1 recombinants. Due to the transient nature of their work, long-distance truck drivers (LDTDs) have a comparatively high potential to become infected with HIV-1 and further spread virus to other individuals in the area they travel within. In this study, we hypothesized that Burmese LDTDs crossing the China-Myanmar border frequently may potentially be involved in the cross-border transmission of HIV, and contribute to the extremely high prevalence of HIV-1 inter-subtype recombinants in this border region. METHODS A molecular epidemiology study was conducted among 105 Burmese LDTDs between 2008 and 2010. HIV-1 genetic fragments including p17, pol, vif-vpr, vpr-env, and C2V3 were amplified and sequenced. The subtype characterization and HIV-1 transmission were determined by both phylogenetic and phylogeographic analyses. RESULTS Diverse forms of HIV-1, including subtypes CRF01_AE (41.9%), C (8.6%), B (4.8%), CRF02_AG (1.0%), and inter-subtype recombinants (33.3%), as well as dual infection (10.5%), were detected among the tested LDTDs. Phylogeographic analyses based on pure subtype revealed that 77.8% Burmese LDTDs acquired HIV-1 infection in Yunnan, and the others in Myanmar. Both the C-related and CRF01_AE-related recombinants from these LDTDs appeared to have close genetic relationship with those from IDUs in Myanmar and Dehong. CONCLUSIONS Burmese LDTDs may contribute to HIV-1 transmission along the China-Myanmar border. The results may provide some new perspective for understanding the on-going generation and prevalence of HIV-1 recombinants in the border region.

Abstract
Background Guangxi has become one of the provinces with the most severe HIV-1 epidemic in China, where heterosexual contact is the dominant transmission route. However, data of acute HIV infections and HIV incidence among female sex workers (FSWs) from low-grade venues are scant. Methods A cross-sectional survey was performed among FSWs from low-grade venues in Guangxi. HIV antibody screening was performed by rapid testing (RT). HIV antibody–negative specimens were screened by pooled nucleic acid amplification testing (NAAT) for acute HIV infections. HIV antibody-positive specimens were further analyzed by Western blot (WB), followed by an HIV-1 BED capture enzyme immunoassay (BED-CEIA) to identify the recent infections. HIV-1 incidence was estimated by the data of pooled NAAT and BED-CEIA, respectively. Results A total of 7936 FSWs were recruited and answered the questionnaires. We successfully collected the blood samples from 6469 (81.5%) participants, of which 139 (2.1%) were HIV antibody–positive and 6330 (97.9%) were HIV antibody-negative by RT. With pooled NAAT, 7 cases were found to be HIV RNA positive, representing an additional 5.0% of HIV-infected persons and an estimated HIV incidence of 1.45 (95% CI: 1.17–1.76) per 100 person years. There were 137 positive and 2 indeterminate by WB, of which 124 (90.5%) positive specimens were subjected to BED-CEIA testing identifying 28 recent infections. The HIV incidence determined by BED-CEIA testing was 1.04 (95% CI: 0.65–1.43) per 100 person years. The overall prevalence of HIV among FSWs from low-grade venues in Guangxi was 2.2% (95% CI: 1.9–2.6). Conclusions We found that the addition of HIV RNA screening to routine HIV antibody testing significantly improved the detection of HIV infection among FSWs from low-grade venues in Guangxi. Our findings also provided the useful baseline data of HIV incidence among this population for targeting local HIV prevention, intervention, monitoring and treatment.

Abstract
Human immunodeficiency virus type 1 (HIV-1) subtype CRF01_AE is transmitted mainly by sexual activity in Guangxi, southwestern China. Other subtypes, including CRF07_BC, CRF08_BC, and subtype B, are also prevalent in this region. Cocirculation of multiple subtypes, as well as a high rate of drug use, creates favorable conditions for the emergence of recombinant viruses in Guangxi. In the present study, we identified a new HIV-1 unique recombinant form (CRF01_AE /08BC) transmitted from the infected index patient to his seronegative sexual partner. This is the first near full-length genome characterization of a CRF01_AE /08BC recombinant virus in Guangxi, and provides an important basis for future analysis on potential new recombinant transmission events.
