Abstract
OBJECTIVE To provide information on clinical, virological, and molecular epidemiological characteristics for early identification, diagnosis, and treatment of acute HIV infection (AHI). METHODS A retrospective study was conducted with patients with AHI from 2012 to 2017 in West China Hospital. RESULTS A total of 47 patients with AHI were found using a fourth-generation kit. Thirteen (27.66%) of these patients were negative if tested by third-generation tests. Median age of patients with AHI was 26 and 91.49% of them were males. Homosexual contact was responsible for 46.81% of AHI transmission. Among the individuals with AHI, 80.85% were outpatients. Common symptoms/signs were fever, headache, rash, cough and sputum, and sore throat. The syphilis coinfection rate was 17.24%. Most of the AHI was distributed in Fiebig stages IV (61.70%) and II (27.66%) with different clinical and virological characteristics. The increasing trend of cut-off index values was obvious in the course of AHI, helpful for auxiliary diagnosis. The main genetic forms of AHI were CRF07_BC and CRF01_AE, and a rare subtype CRF55_01B in Sichuan province was found. The drug resistance mutation rate was relatively high (17.65%) and five different mutations were identified. CONCLUSIONS Fourth-generation assays are strongly recommended for screening AHI compared to third-generation ones. Different clinical and virological characteristics in different Fiebig stages were found. Young individuals and outpatients were the majority of patients with AHI and this deserves special attention. Attention should also be paid to the rare CRF55_01B in Sichuan province and surveillance of HIV resistance ought to be strengthened.

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
The aim of this meta-analysis was to provide a comprehensive overview of human immunodeficiency virus (HIV)-1 subtypes and to investigate temporal and geographical trends of the HIV-1 epidemic among men who have sex with men (MSM) in China. Chinese and English articles published between January 2007 and December 2017 were systematically searched. Pooled HIV-1 prevalence was calculated, and its stability was analysed using sensitivity analysis. Subgroups were based on study time period, sampling area and prevalence. Publication bias was measured using Funnel plot and Egger's test. A total of 68 independent studies that included HIV-1 molecular investigations were eligible for meta-analysis. Circulating recombinant form (CRF) 01_AE (57.36%, 95% confidence interval (CI) 53.76–60.92) was confirmed as the most prevalent HIV-1 subtype among MSM in China. Subgroup analysis for time period found that CRF01_AE steadily increased prior to 2012 but decreased during 2012–2016. Further whereas CRF07_BC increased over time, B/B′ decreased over time. CRF55_01B has increased in recent years, with higher pooled estimated rate in Guangdong (12.22%, 95% CI 10.34–13.17) and Fujian (8.65%, 95% CI 4.98–13.17) provinces. The distribution of HIV-1 subtypes among MSM in China has changed across different regions and periods. HIV-1 strains in MSM are becoming more complex. Long-term molecular monitoring in this population remains necessary for HIV-1 epidemic control and prevention.

Abstract
New recombinant variants are a predominant challenge for preventing the spread of the HIV-1 epidemic. In this study, we confirmed a novel HIV-1 CRF07_BC/CRF55_01B recombinant form for the first time, which was isolated from a male patient in Jiangmen, China. The genomic sequence of the variant with four CRF55_01B segments inserted into the CRF07_BC backbone is 8,510 bp in length, extending from nucleotides 669 to 9,293 according to the HXB2 genome. Specifically, the recombinant strain contains site mutations associated with drug resistance.

Phylogenetic analysis highlights the role of older people in the transmission of HIV-1 in Fuyang, Anhui Province, China. BMC Infect Dis 2019; 19:562. [PMID: 31248372 PMCID: PMC6598234 DOI: 10.1186/s12879-019-4187-9] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2019] [Accepted: 06/12/2019] [Indexed: 01/16/2023] Open
Abstract
Background The proportion of older HIV-1 infected people in China has increased rapidly in recent years. Elucidation of the transmission characteristics of this high-risk population subgroup is helpful for the development of tailored interventions. Methods A phylogenetic analysis was performed that uses available HIV-1 pol sequences amplified with nested RT-PCR from plasma samples of all newly diagnosed participants spanning from October 2017 to September 2018 in Fuyang, Anhui Province. Transmission clusters were identified as two or more sequences that shared a corresponding node with an aLRT-SH value ≥90 in the maximum-likelihood phylogenetic tree and had an overall mean genetic distance of ≤1.5%. A local transmission cluster was defined as a cluster that had more than 80% of its sequences from Fuyang. The role of older people in local HIV-1 transmission was determined using an integration of molecular and demographic data. Results Of 362 available sequences, 14 subtypes, and 28 local transmission clusters were identified. It was found that the proportion of older people in the local transmission cluster (69/77, 89.61%) was much higher than that of younger people (46/114, 40.35%) (χ2 test, P < 0.001). In the pretreatment drug resistance analysis, the proportion of sequences with PDRMs in the local transmission cluster was not significantly different between the older people group (57.14%, 4/7) and non-old-aged group (11.11%, 1/9) (Fisher’s exact test, P > 0.05). Conclusion By combining phylogenetic analyses with demographic data, more detailed information was provided about the local transmission structure in Fuyang. These findings suggested that older people play an important role in local transmission, and more tailored interventions for this population subgroup are urgently needed.

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 results of the molecular-epidemiological analysis of HIV-1 variants circulating in Arkhangelsk and Murmansk - northern seaports of Russia - were presented. In these seaports the HIV-1 variants belonging to subtype A1 were predominant (93% in Murmansk, 83% in Arkhangelsk). In addition to these variants, viruses of other subtypes such as B, C, D and recombinant forms CRF02_AG and CRF03_AB were identifed. The heterogeneity of circulating HIV-1 variants was higher in Arkhangelsk than in Murmansk. According to the results of phylogenetic analysis, subtype A1 sequences formed the common branch with nucleotide sequences of IDU-A strains found in other regions of Russia. HIV-1 variants of subtype B sub-clustered with sequences of East European B-variants. The recombinant strains CRF02_AG formed the common branch with HIV-1 sequences from Central Asia republics of the former USSR. Among 124 therapy-naive patients from Arkhangelsk and Murmansk (n = 124) the transmitted resistance was less than 5%.

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
Understanding HIV-1 transmission dynamics is relevant to both screening and intervention strategies of HIV-1 infection. Commonly, HIV-1 transmission chains are determined based on sequence similarity assessed either directly from a sequence alignment or by inferring a phylogenetic tree. This review is aimed at both nonexperts interested in understanding and interpreting studies of HIV-1 transmission, and experts interested in finding the most appropriate cluster definition for a specific dataset and research question. We start by introducing the concepts and methodologies of how HIV-1 transmission clusters usually have been defined. We then present the results of a systematic review of 105 HIV-1 molecular epidemiology studies summarizing the most common methods and definitions in the literature. Finally, we offer our perspectives on how HIV-1 transmission clusters can be defined and provide some guidance based on examples from real life datasets.

Characterization of Humoral Immune Responses against Capsid Protein p24 and Transmembrane Glycoprotein gp41 of Human Immunodeficiency Virus Type 1 in China. PLoS One 2016; 11:e0165874. [PMID: 27802337 PMCID: PMC5089721 DOI: 10.1371/journal.pone.0165874] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2016] [Accepted: 10/19/2016] [Indexed: 11/18/2022] Open
Abstract
The objective of this study was to extend our previous research and to further characterize the humoral immune responses against HIV-1 p24, gp41 and the specific peptides carrying the immunodominant epitopes (IDEs) that react with human serum samples from HIV-1-infected individuals in China. We found that the majority (90.45%, 180/199) of the samples did not react with any of the three HIV-1 p24 peptides carrying IDEs, but did react with the recombinant full-length p24, suggesting that these samples tested in China were primarily directed against the conformational epitopes of HIV-1 p24. In contrast, 84.54% (164/194) of the samples reacted with at least one HIV-1 linear gp41 peptide, in particular the gp41-p1 peptide (amino acids 560-616). Both recently and long-term HIV-1-infected individuals displayed similar humoral immune responses against the recombinant gp41. However, samples from long-term HIV-1-infected subjects but not from recently infected subjects, showed a very strong reaction against the gp41-p1 peptide. The different response patterns observed for the two groups against the gp41 and the peptide gp41-p1 were statistically significant (P<0.01, Chi-square test). These results have direct relevance and importance for design of improved HIV-1 p24 detection assays and the gp41- based immunoassay that can be used to reliably distinguish recent and long-term HIV-1 infection.

Abstract
HIV is responsible for one of the largest viral pandemics in human history. Despite a concerted global response for prevention and treatment, the virus persists. Thus, urgent public health action, utilizing novel interventions, is needed to prevent future transmission events, critical to eliminating HIV. For public health planning to prove effective and successful, we need to understand the dynamics of regional epidemics and to intervene appropriately. HIV molecular epidemiology tools as implemented in phylogenetic, phylodynamic and phylogeographic analyses have proven to be powerful tools in public health planning across many studies. Numerous applications with HIV suggest that molecular methods alone or in combination with mathematical modelling can provide inferences about the transmission dynamics, critical epidemiological parameters (prevalence, incidence, effective number of infections, Re, generation times, time between infection and diagnosis), or the spatiotemporal characteristics of epidemics. Molecular tools have been used to assess the impact of an intervention and outbreak investigation which are of great public health relevance. In some settings, molecular sequence data may be more readily available than HIV surveillance data, and can therefore allow for molecular analyses to be conducted more easily. Nonetheless, classic methods have an integral role in monitoring and evaluation of public health programmes, and should supplement emerging techniques from the field of molecular epidemiology. Importantly, molecular epidemiology remains a promising approach in responding to viral diseases.

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.

Evolving molecular epidemiological profile of human immunodeficiency virus 1 in the southwest border of China. PLoS One 2014; 9:e107578.

Abstract
Background We have previously reported in Xishuangbanna (Banna) Dai Autonomous Prefecture, a well-developed tourist destination in the southwest border of China, that HIV-1 transmitted dominantly through heterosexual contact with less divergent genotypes and few drug resistant mutations [1]. Due to the rapid increase of newly diagnosed HIV-1 cases per year in Banna in recent years, it’s important to evaluate the evolution of HIV-1 molecular epidemiology for the better understanding of ongoing HIV-1 outbreak in this region. Methodology/Principal Findings By sequencing of HIV-1 pol genes and phylogenetic analysis, we conducted a molecular epidemiologic study in 352 HIV-1-seropositive highly active antiretroviral treatment (HAART)-naïve individuals newly diagnosed at the Banna Center for Disease Control and Prevention between 2009 and 2011. Of 283 samples (84.1% taken from heterosexually acquired adults, 10.6% from needle-sharing drug users, 2.8% from men who have sex with men, 0.4% from children born from HIV-1-infected mothers, and 2.1% remained unknown) with successful sequencing for pol gene, we identified 108 (38.2%) HIV-1 subtype CRF08_BC, 101 (35.7%) CRF01_AE, 49 (17.3%) CRF07_BC, 5 (1.8%) C/CRF57_BC, 3 (1.1%) B’, 1 (0.4%) B/CRF51_01B, and 16 (5.7%) unique recombinants forms. Among these infected individuals, 104 (36.7%) cases showed drug resistant or resistance-relevant mutations, and 4 of them conferring high-level resistance to 3TC/FTC, EFV/NVP or NFV. Phylogenetic analysis revealed 21 clusters (2–7 sequences) with only 21.2% (60/283) sequences involved. Conclusion/Significance In contrast to our previous findings, CRF08_BC, replaced CRF01_AE, became the dominant genotype of HIV-1 in Banna prefecture. The viral strains with drug resistance mutations were detected frequently in newly diagnosed HIV-1-infected individuals in this region.

Abstract
Little is known about HIV drug resistance (HIVDR) in newly diagnosed HIV-infected adults in eastern China where the HIV epidemic is spreading predominantly through sexual contact. During 2008-2011, newly HIV-diagnosed adults in Taizhou prefecture, Zhejiang province in eastern China were examined for HIVDR by amplifying and sequencing the HIV-1 pol gene. Of 447 genotyped participants, 53·7% were infected with CRF01_AE, 20·1% with CRF07_BC, 12·5% with subtype B, and 11·6% with CRF08_BC. Most of the participants had one or more minor genetic mutations in the pol gene that are associated with HIVDR. Twelve (2·7%) participants met the standard guidelines of having low to high HIVDR, suggesting that the prevalence of HIVDR in newly HIV-diagnosed adults was low in the study area and current antiretroviral therapy (ART) regimens are likely to remain effective. However, given high frequency of minor HIVDR in HIV patients and the scaling up of ART programmes in China, larger HIVDR surveillance programmes are needed.

Abstract
We sought to identify the prevalent subtypes and study the genetic variation of HIV-1 circulating in HIV infections in Harbin City, China. Forty-seven samples from the env V3-V4 region were successfully sequenced and analyzed, which involved thirty-one men who have sex with men (MSM), eight heterosexuals, seven former plasma donors (FPD)/blood transfusion recipients (BT), and one injection drug user (IDU). In all, 46.8% of CRF01_AE, 40.4% of subtype B, and 12.8% of CRF07_BC were identified. CRF01_AE (64.5%) was the dominant strain in MSM, and subtype B (81.2%) was the chief strain in other infected subjects except for the MSM population. Among all the genotypes, the B subtype possesses greater diversity of the tetramer on the tip of V3 loop than CRF07_BC and CRF01_AE, in which the peculiar GWGR was commonly found. Because nationwide there is a trend toward the increasing presence of CRF01_AE, a consecutive surveillance campaign was necessary among all HIV vulnerable populations in this locality.
