Abstract
Strategies to improve the scale-up of antiretroviral therapy (ART) for patients with HIV in Trinidad and Tobago, including the adoption of the "Test and Treat All" policy, have accompanied an increase in the number of patients with pretreatment HIV drug resistance (PDR) in the country. However, the scale of this public health problem is not well established. The objective of this study was to estimate the prevalence of PDR and evaluate its impact on viral suppression among patients with HIV receiving care at a large HIV treatment center in Trinidad and Tobago. We retrospectively analyzed data from the Medical Research Foundation of Trinidad and Tobago of patients newly diagnosed with HIV who had HIV genotyping performed. PDR was defined as having at least one drug-resistant mutation. We assessed the impact of PDR on achieving viral suppression within 12 months of ART initiation, using a Cox extended model. Among 99 patients, 31.3% had PDR to any drug, 29.3% to a non-nucleoside reverse transcriptase inhibitor (NNRTI), 3.0% to a nucleoside reverse transcriptase inhibitor, and 3.0% to a protease inhibitor. Overall, 67.1% of the patients who initiated ART (n = 82) and 66.7% (16/24) of patients with PDR achieved viral suppression within 12 months. We found no significant association between PDR status and achieving viral suppression within 12 months [adjusted hazard ratio: 1.08 (95% confidence interval: 0.57-2.04)]. There is a high prevalence of PDR in Trinidad and Tobago, specifically driven by NNRTI resistance. Although we found no difference in virologic suppression by PDR status, there is an urgent need for an effective HIV response to address the many drivers of virologic failure. Accelerating access to affordable, quality-assured generic dolutegravir and adopting it as the preferred first-line ART therapy are critical.

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

Age and CD4+ T cell counts are inversely associated with HIV drug resistance mutations in treatment naive female sex workers. Medicine (Baltimore) 2023; 102:e34060.

Abstract
The increasing prevalence of human immunodeficiency virus (HIV) drug resistance mutations (HIVDRM) in untreated seropositive persons has consequences for future treatment options. This is extremely important in key populations such as female sex workers (FSWs), where the prevalence of pretreatment drug resistance (PDR) and associated risk factors are unknown. In this study, we analyzed PDR and associated risk factors in recently diagnosed and treatment-naive FSWs in Nairobi, Kenya. In this cross-sectional study, we used 64 HIV-seropositive plasma samples collected from FSWs between November 2020 and April 2021. To identify HIVDRM, the pol gene was amplified and genotyped using sanger sequencing. The effects of age, tropism, CD4+ T cell count, subtype, and location on HIVDRM counts were examined using Poisson regression. Overall, the prevalence of PDR was 35.9% (95% CI: 24.3-48.9), which was strongly influenced by K103N and M184V mutations, which confer resistance to non-nucleoside reverse transcriptase inhibitors (NNRTIs) and nucleoside reverse transcriptase inhibitors (NRTI), respectively. Subtype A1 was predominant followed by subtype D with a notable increase in inter-subtype recombinants. We found statistically significant evidence that age was inversely related to HIVDRM. A FSW who is 1 year older had 12% less HIVDRM (incidence rate ratios [IRR]: 0.88; 95% CI: 0.82-0.95; P < .001), after adjusting for CD4+ T cell count, subtype, location, and tropism. Similarly, an increase in CD4+ T cell count by 1 unit, was associated with 0.4% fewer HIVDRM (IRR: 0.996; 95% CI: 0.994-0.998; P = .001), while controlling for the other variables. HIV-1 tropism was not associated with HIVDRM counts. In conclusion, our findings show a high prevalence of NNRTIs. Lower CD4+ T cell counts and younger age were significant risk factors that influenced HIVDRM loads. This finding underscores the relevance of targeted interventions and the importance of continuing to focus on FSWs as a way of addressing the HIV epidemic.

Abstract
Intimate partner violence (IPV) is associated with a higher risk of contracting HIV and developing worse HIV outcomes. This cross-sectional, mixed methods study presents data on IPV using the Conflicts Tactics Scale (CTS2-S) among 180 persons with HIV in Lima, Peru, as well as qualitative interviews with 7 of them and 18 of their community caregivers. This study used data collected for a randomized controlled trial (RCT), CASAommunity Based Accompaniment with Supervised Antiretrovirals (CASA) Community-based Accompaniment with Supervised Antiretrovirals (CASA). Physical or sexual IPV was self-reported in 82 (45.6%) of participants reporting having been in a relationship in the last year and 59,8% of those were involved in bidirectional violence. Coping subscales, social support, and stigma were associated with IPV. Intimate partner violence negatively impacted patient adherence to medication and care, particularly during times of severe conflict. In conclusion, profound psychosocial vulnerability-including low social support, substance use as coping, and HIV stigma-contextualize IPV among people with HIV. Bidirectional violence often evolved over time as victims negotiated inter-personal strategies for survival, including retaliation. Interventions should focus on a deeper understanding IPV and facilitating of coping mechanisms to help people with HIV stay in care.

Abstract
Adolescent girls and young women (AGYW) in sub-Saharan Africa may benefit from pre-exposure prophylaxis (PrEP), yet stigma may limit PrEP acceptance and continuation. We examined factors associated with PrEP use stigma among 307 participants of the EMPOWER trial (2016-2018), an unblinded randomized controlled trial among HIV-negative, AGYW, aged 16-24, in South Africa and Tanzania. The 6-item, brief-PrEP use stigma scale (B-PSS) had high internal reliability. At the end of the trial, 34.2% of study participants reported any PrEP use stigma. Three latent classes were observed, reflecting low (46.9%), medium (31.9%), and high (21.2%) reported PrEP use stigma. Disclosure of PrEP use to sexual partner and belief that PrEP prevents HIV were associated with less reported PrEP use stigma. Conversely, participants who reported fear and shame about people living with HIV were more likely to report PrEP use stigma. Our validated tool and findings will enable practitioners to identify AGYW at high risk of PrEP use stigma who may benefit from additional support.Pan African clinical trials registry PACTR202006754762723, 5 April 2020, retrospectively registered.

Abstract
HIV-1 genetic diversity and resistance profile might change according to the risky sexual behavior of the host. To show this, we recruited 134 individuals between the years 2015 and 2017 identified as transgender women sex workers (TWSW, n = 73) and Heterosexual Military Officers (HET-MO, n = 61). After obtaining informed consent, we collected a blood sample to perform the HIV genotyping, CD4 cell count, and viral load. We used bioinformatics approaches for detecting resistance mutations and recombination events. Epidemiological data showed that both groups reported sexually transmitted diseases and they were widespread among TWSW, especially syphilis and herpes virus (35.6%). Illegal drugs consumption was higher among TWSW (71.2%), whereas condom use was inconsistent for both HET-MO (57.4%) and TWSW (74.0%). TWSW showed the shortest time exposition to antiretroviral therapy (ART) (3.5 years) and the lowest access to ART (34.2%) that conducted treatment failure (>4 logs). HIV-1 sequences from TWSW and HET-MO were analyzed to determine the genetic diversity and antiretroviral drug resistance. Phylogeny analysis revealed 125 (93%) cases of subtype B, 01 subtype A (0.76%), 07 (5.30%) BF recombinants, and 01 (0.76%) AG recombinant. Also, TWSW showed a higher recombination index (9.5%, 7/73) than HET-MO (1.5%, 1/68). HET-MO only showed acquired resistance (26.23%, 16/61), whereas TWSW showed both acquired as transmitted resistance (9.59% for each). In conclusion, TWSW and HET-MO showed significant differences considering the epidemiological characteristics, genetic diversity, recombination events, and HIV resistance profile.

Abstract
A two-strain model, comprising of drug-sensitive and drug-resistant strains, is proposed for the dynamics of Human Immunodeficiency Virus (HIV) spread in a community. A treatment model is introduced by taking drug adherence into account. The treatment-free model is analyzed for the effect of treatment availability and drug adherence on disease dynamics. The analysis revealed that for the treatment-free model, at least one strain faces competitive exclusion, and co-existence of both strains is not possible. On the contrary, both strains may co-exist in presence of treatment. The analysis carried out was both local, as well as global. A comprehensive bifurcation analysis showed periodic behaviour and all solutions approached a stable limit cycle for a wide range of parametric values. Overall, we concluded that the treatment availability and drug adherence play a significant role in determining the dynamics of HIV spread. Numerical simulations are performed to validate the analytical results using MATLAB.

Abstract
BACKGROUND Transgender women (TW) in Peru are disproportionately affected by HIV. The role that cisgender men who have sex with TW (MSTW) and their sexual networks play in TW's risk of acquiring HIV is not well understood. We used HIV sequences from TW, MSTW, and cisgender men who have sex with men (MSM) to examine transmission dynamics between these groups. METHODS We used HIV-1 pol sequences and epidemiologic data collected through three Lima-based studies from 2013 to 2018 (n = 139 TW, n = 25 MSTW, n = 303 MSM). We identified molecular clusters based on pairwise genetic distance and used structured coalescent phylodynamic modeling to estimate transmission patterns between groups. FINDINGS Among 200 participants (43%) found in 62 clusters, the probability of clustering did not differ by group. Both MSM and TW were more likely to cluster with members of their own group than would be expected based on random mixing. Phylodynamic modeling estimated that there was frequent transmission from MSTW to TW (67·9% of transmission from MSTW; 95%CI = 52·8-83·2%) and from TW to MSTW (76·5% of transmissions from TW; 95%CI = 65·5-90·3%). HIV transmission between MSM and TW was estimated to comprise a small proportion of overall transmissions (4·9% of transmissions from MSM, and 11·8% of transmissions from TW), as were transmissions between MSM and MSTW (7·2% of transmissions from MSM, and 32·0% of transmissions from MSTW). INTERPRETATION These results provide quantitative evidence that MSTW play an important role in TW's HIV vulnerability and that MSTW have an HIV transmission network that is largely distinct from MSM.

Abstract
BACKGROUND While a growing number of studies focus on men who have sex with men (MSM), they typically ignore the heterogeneity of gender minorities within the MSM population. The recognition of new sub-groups among gender minorities (i.e., transgender and gender non-conforming), who also identify as MSM, play a considerable role in new HIV infections in China. Information on the psychosocial factors and HIV-related sexual behaviors require further consideration to understand the prevalence of HIV infection among MSM within these gender minority sub-groups. METHODS From September 2017 to January 2018, MSM without HIV were recruited in Wuhan, Nanchang, and Changsha cities in China. Participants were asked to fill out a structured self-administered questionnaire to assess depression, perceived social support, resilience, identity concealment, and HIV-related risky sexual behaviors. RESULTS A total of 715 MSM completed the structured questionnaire, the number of MSM identifying as gender minorities were 63 and accounted for 8.8% of the population. Compared to the cisgender MSM population, transgender MSM were more likely to have a one-night stand/occasional partner (AOR = 3.49, 95% CI =1.02-11.98), to have sex after drug use in the past 6 months (AOR = 2.57, 95%CI =1.05-6.29), and to have reported a significantly lower likelihood of identity concealment (mean difference = - 3.30, 95%CI = -5.86, - 0.74, P = 0.01). CONCLUSIONS The findings highlight the significance of providing targeted interventions for different gender minorities within the MSM population. Research is required to further understand the relationship between gender identity, mental health, and HIV-related sexual behaviors.

Increase in HIV-1-transmitted drug resistance among ART-naïve youths at the China-Myanmar border during 2009 ~ 2017. BMC Infect Dis 2021; 21:93. [PMID: 33478415 PMCID: PMC7818912 DOI: 10.1186/s12879-021-05794-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2020] [Accepted: 01/12/2021] [Indexed: 11/16/2022] Open
Abstract
Background HIV-transmitted drug resistance (TDR) is found in antiretroviral therapy (ART)-naïve populations infected with HIV-1 with TDR mutations and is important for guiding future first- and second-line ART regimens. We investigated TDR and its effect on CD4 count in ART-naïve youths from the China-Myanmar border near the Golden Triangle to better understand TDR and effectively guide ART. Methods From 2009 to 2017, 10,832 HIV-1 infected individuals were newly reported along the Dehong border of China, 573 ART-naïve youths (16 ~ 25 y) were enrolled. CD4 counts were obtained from whole blood samples. HIV pol gene sequences were amplified from RNA extracted from plasma. The Stanford REGA program and jpHMM recombination prediction tool were used to determine genotypes. TDR mutations (TDRMs) were analyzed using the Stanford Calibrated Population Resistance tool. Results The most common infection route was heterosexuals (70.51%), followed by people who inject drugs (PWID, 19.20%) and men who have sex with men (MSM) (8.90%). The distribution of HIV genotypes mainly included the unique recombinant form (URF) (44.08%), 38.68% were CRFs, 13.24% were subtype C and 4.04% were subtype B. The prevalence of TDR increased significantly from 2009 to 2017 (3.48 to 9.48%) in ART-naïve youths (4.00 to 13.16% in Burmese subjects, 3.33 to 5.93% in Chinese subjects), and the resistance to non-nucleoside reverse transcriptase inhibitors (NNRTIs), nucleoside and nucleotide reverse transcriptase inhibitors (NRTIs), and protease inhibitors (PIs) were 3.49, 2.62, and 0.52%, respectively. Most (94.40%, n = 34) of HIV-1-infected patients with TDRM had mutation that conferred resistance to a single drug class. The most common mutations Y181I/C and K103N, were found in 7 and 9 youths, respectively. The mean CD4 count was significantly lower among individuals with TDRMs (373/mm3 vs. 496/mm3, p = 0.013). Conclusions The increase in the prevalence of HIV-1 TDR increase and a low CD4 count of patients with TDRMs in the China-Myanmar border suggests the need for considering drug resistance before initiating ART in HIV recombination hotspots.
