Abstract
OBJECTIVES There is conflicting data regarding the response of older people with HIV (PWH) to antiretroviral therapy (ART). The objective of this study was to evaluate the long-term immunological and virological responses, changes in regimen, and adverse drug reactions (ADRs) in older participants (50+ years) compared with younger (18-34 years) and middle-aged (35-49 years) PWH. METHODS A retrospective review of medical records was conducted on 1622 participants who received ART in Yunnan Province, China, from 2010 to 2019. The study compared CD4+ T-cell counts, CD4+/CD8+ ratio, and relative numbers between different groups using the Kruskal-Wallis test. Cox proportional hazards regression models were used to identify variables associated with the occurrence of immune reconstitution insufficiency. The rates of immune reconstitution, incidence of ADRs, and rates of treatment change were analyzed using the chi-squared test or Fisher's exact test. RESULTS Over 95% achieved viral load 200 copies/ml or less, with no age-related difference. However, older participants exhibited significantly lower CD4+ T-cell counts and CD4+/CD8+ recovery post-ART (P < 0.001), with only 32.21% achieving immune reconstitution (compared with young: 52.16%, middle-aged: 39.29%, P < 0.001) at the end of follow-up. Middle-aged and elderly participants changed ART regimens more because of ADRs, especially bone marrow suppression and renal dysfunction. CONCLUSION Although the virological response was consistent across age groups, older individuals showed poorer immune responses and higher susceptibility to side effects. This underscores the need for tailored interventions and comprehensive management for older patients with HIV.

Abstract
In this article, we present a mathematical model for human immunodeficiency virus (HIV)/Acquired immune deficiency syndrome (AIDS), taking into account the number of CD4+T cells and antiretroviral treatment. This model is developed based on the susceptible, infected, treated, AIDS (SITA) framework, wherein the infected and treated compartments are divided based on the number of CD4+T cells. Additionally, we consider the possibility of treatment failure, which can exacerbate the condition of the treated individual. Initially, we analyze a simplified HIV/AIDS model without differentiation between the infected and treated classes. Our findings reveal that the global stability of the HIV/AIDS-free equilibrium point is contingent upon the basic reproduction number being less than one. Furthermore, a bifurcation analysis demonstrates that our simplified model consistently exhibits a transcritical bifurcation at a reproduction number equal to one. In the complete model, we elucidate how the control reproduction number determines the stability of the HIV/AIDS-free equilibrium point. To align our model with the empirical data, we estimate its parameters using prevalence data from the top four countries affected by HIV/AIDS, namely, Eswatini, Lesotho, Botswana, and South Africa. We employ numerical simulations and conduct elasticity and sensitivity analyses to examine how our model parameters influence the control reproduction number and the dynamics of each model compartment. Our findings reveal that each country displays distinct sensitivities to the model parameters, implying the need for tailored strategies depending on the target country. Autonomous simulations highlight the potential of case detection and condom use in reducing HIV/AIDS prevalence. Furthermore, we identify that the quality of condoms plays a crucial role: with higher quality condoms, a smaller proportion of infected individuals need to use them for the potential eradication of HIV/AIDS from the population. In our optimal control simulations, we assess population behavior when control interventions are treated as time-dependent variables. Our analysis demonstrates that a combination of condom use and case detection, as time-dependent variables, can significantly curtail the spread of HIV while maintaining an optimal cost of intervention. Moreover, our cost-effectiveness analysis indicates that the condom use intervention alone emerges as the most cost-effective strategy, followed by a combination of case detection and condom use, and finally, case detection as a standalone strategy.

Abstract
Advancements in long-acting (LA) HIV treatment and cure research with analytical treatment interruptions (ATIs) have generated important scientific and implementation questions. There is an urgent need to examine challenges navigating the evolving HIV treatment and cure research landscape. From August to October 2022, we conducted 26 semistructured interviews with biomedical researchers and community members representing a predominantly woman demographic to explore the complexity of navigating the rapidly evolving HIV therapeutic and HIV cure research landscape. We purposively sampled individuals recruited from the AIDS Clinical Trials Group and the Martin Delaney Collaboratories for HIV Cure Research. Audio files were transcribed verbatim and analyzed through a thematic approach, using an inductive and iterative process. Among 26 participants, 10 were biomedical researchers and 16 community members, including 11 were people with HIV. Three main themes emerged: (1) We are at a pivotal moment in the evolving landscape of HIV therapeutics and LA HIV treatment and HIV cure research should not be siloed but considered together; (2) There are challenges with engagement in HIV cure research and in switching between oral daily antiretroviral treatment and LA formulations and, mainly, the prolonged pharmacokinetic tail of these compounds matched with limited patient education about their impacts; and (3) There are unique opportunities as a result of this evolving therapeutic landscape, including the key role of decision support for people with HIV, centering around patient autonomy, and the need to learn from the lived experiences of people with HIV who choose LA treatment and/or participation in HIV cure research. Despite a bias toward the woman gender, our study identifies key considerations for navigating concurrent LA HIV treatment and HIV cure research with ATIs from both community members and biomedical researchers' perspectives. Achieving optimal HIV control remains a formidable challenge, necessitating robust interdisciplinary collaborations and engagement with key stakeholders.

Abstract
This study aimed to elucidate the intrinsic and extrinsic resilience resources among people living with HIV (PLWH) during the Covid pandemic. Autoethnographic video diaries from 29 PLWH from Argentina, UK, Philippines, Zimbabwe, and Trinidad and Tobago were included. Data were thematically analysed and validated with community partners and a video was co-produced. PLWH displayed a readiness to adopt healthy behaviours and engage in optimistic and constructive thinking about the future. Hobbies and daily activities, supportive relationships with peers living with HIV, family and friends, opportunities to mobilise and contribute to their communities in meaningful ways, supportive healthcare providers and reliable access to antiretroviral treatment helped foster psychological resilience among PLWH. The extrinsic resilience resources also supported positive physical health outcomes among PLWH through improved medication adherence.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) infection can be associated with oral mucosal diseases, including oral candidiasis and HPV infection, which are putative indicators of the immune status. AIM AND METHODS This retrospective cross-sectional study was aimed at assessing the prevalence of HIV-related oral mucosal lesions in a cohort of Italian HIV+ patients regularly attending the Clinics of Infectious Diseases. RESULTS One hundred seventy-seven (n = 177) patients were enrolled and 30 (16.9%) of them showed HIV-related diseases of the oral mucosa. They were mainly found in male patients over 35 years old, undergoing Combination Antiretroviral Therapy (cART), and with CD4+ count < 500/µL. Oral candidiasis was the most common HIV-related oral lesion. No significant correlations could be detected between the prevalence of HPV infection and other clinical parameters (lymphocyte count, cART treatment and viral load). CONCLUSIONS HIV-related oral mucosal diseases can correlate with immunosuppression. Early diagnosis and management of oral lesions in HIV+ patients should be part of the regular follow-up, from a multidisciplinary perspective of collaboration between oral medicine and infectious disease specialists, in an attempt to reduce morbidity due to oral lesions and modulate antiretroviral therapy according to the patient's immune status.

Abstract
The use of long-acting antiretroviral regimens will not be suitable for all people living with HIV for various reasons (previous virological failure with drugs of the same class, side effects, logistic difficulties, and costs). We think that short-cycle therapies could represent a feasible and valuable option for antiretroviral treatment optimization in selected individuals. So here we review clinical evidence about efficacy of short-cycle therapy in suppressed HIV-infected patients.

Abstract
Person-centered care (PCC) aims to improve client's experiences in HIV care while advancing outcomes. This study team developed the PCC assessment tool (PCC-AT) to assess PCC service performance in HIV treatment settings in Ghana. Study objectives aimed to describe the range of PCC-AT scores within and across study facilities and examine the feasibility of PCC-AT implementation in diverse HIV treatment settings. The PCC-AT was piloted at five health facilities providing HIV services among 37 staff. Immediately following each pilot, focus group discussions (FGDs) were conducted to gather feasibility data. Thematic qualitative analysis was conducted on translated FGD transcripts. Across facilities, providers scored highest in the staffing domain, followed by service provision, and direct client support. Time required to implement the PCC-AT averaged 62 minutes. Providers described the tool as well-structured, user-friendly, relevant, reflective of the core PCC delivery elements, and useful in elucidating actions to improve PCC service delivery across domains. The PCC-AT holds potential to strengthen activities that support clients' broader clinical, mental and psychosocial wellbeing by offering friendly services that attend to each client's holistic needs while contributing progress towards epidemic control.

Abstract
BACKGROUND Early diagnosis and effective antiretroviral therapy (ART) lead to similar life expectancy in people living with HIV (PLWH) compared to the general population. This population faces problems such as decreased bone mineral density (BMD) and increased fracture risk. The aim of this study was to determine the prevalence of osteoporosis in men aged 50 years and over who were PLWH and to determine risk factors and changes in bone metabolism with bone turnover markers. METHODS 79 male PLWH aged 50 years and over were followed up in our outpatient clinic between May 2021 and October 2021. The patients' demographic, clinical, laboratory, and DEXA data were analyzed. Serum levels of bone turnover markers were measured. RESULTS The prevalence of osteopenia, osteoporosis, and normal BMD was found to be 55.7%, 13.9%, and 30.4%, respectively. A correlation was found between low BMD and low body mass index, elapsed time since diagnosis of HIV infection, high rate of use of ART, and long usage time of tenofovir disoproxil fumarate + protease inhibitor. A one-year increase in HIV infection duration was associated with an increased risk of low BMD by 1.246. CONCLUSION Compared to studies conducted on the general population, the prevalence of osteoporosis in male PLWH aged 50 years and older was two times higher. The limited effect of the duration of ART use on low BMD may be due to the patients' histories of replacement therapy. Therefore, to eliminate the negative effects of ART on BMD, it may be beneficial to start replacement therapy when necessary.

Abstract
Rapid advances in the potency, safety, and availability of modern HIV antiretroviral therapy (ART) have yielded a near-normal life expectancy for most people living with HIV (PLWH). Ironically, considering the history of HIV/AIDS (initially called "slim disease" because of associated weight loss), the latest dilemma faced by many people starting HIV therapy is weight gain and obesity, particularly Black people, women, and those who commenced treatment with advanced immunodeficiency. We review the pathophysiology and implications of weight gain among PLWH on ART and discuss why this phenomenon was recognized only recently, despite the availability of effective therapy for nearly 30 years. We comprehensively explore the theories of the causes, from initial speculation that weight gain was simply a return to health for people recovering from wasting to comparative effects of newer regimens vs prior toxic agents, to direct effects of agents on mitochondrial function. We then discuss the implications of weight gain on modern ART, particularly concomitant effects on lipids, glucose metabolism, and inflammatory markers. Finally, we discuss intervention options for PLWH and obesity, from the limitations of switching ART regimens or specific agents within regimens, weight-gain mitigation strategies, and potential hope in access to emerging antiobesity agents, which are yet to be evaluated in this population.

Abstract
Objective This study aims to analyze the efficacy of anti-syphilis treatment and the impact of syphilis events on HIV virology and immunology in HIV/syphilis co-infected patients on long-term antiretroviral therapy (ART) and to investigate the incidence and factors of syphilis recurrence/re-infection/serofast state. The insights derived from this investigation can potentially guide strategies for preventing and managing syphilis and AIDS. Methods A retrospective case-control study was conducted at the AIDS clinic of Peking Union Medical College Hospital from January 2003 to December 2022. The study involved 86 HIV/syphilis co-infected patients and 86 HIV mono-infected patients matched based on age, baseline CD4 + T cell counts, and viral load. We examined the clinical characteristics of HIV/syphilis co-infected patients, evaluated the efficacy of anti-syphilis treatment, and analyzed the dynamic changes in HIV virology and immunology. The Generalized Estimating Equations (GEE) model investigated the factors associated with HIV/syphilis co-infection and syphilis recurrence/reinfection/serofast state. Results Syphilis serofast state was observed in 11.6% (10/86) of HIV/syphilis co-infected patients after treatment, and 33.7% (29/86) had syphilis recurrence or re-infection. The overall effectiveness of syphilis treatment stood at 76.8% (63/82). Notably, the effectiveness of syphilis treatment displayed a significant correlation with baseline syphilis titers exceeding 1:128 (p = 0.003). Over the 10-year follow-up period on ART, the HLA-DR + CD8+/CD8 + % levels in the HIV/syphilis co-infected group were markedly higher than those in the HIV mono-infected group (p < 0.05). However, no significant differences were observed between the two groups regarding HIV viral load, CD4+ T cell counts, CD8+ T cell counts, CD4/CD8 ratio, and CD38 + CD8+/CD8 + % (p > 0.05). GEE analysis model revealed that elevated HLA-DR + CD8+/CD8 + % levels were associated with HIV/syphilis co-infection (OR = 1.026, 95% CI = 1.007-1.046; p = 0.007) and syphilis recurrence/reinfection/serofast state (OR = 1.036, 95% CI = 1.008-1.065; p = 0.012). Conclusion While HIV/syphilis co-infected patients typically receive adequate treatment, the incidence of syphilis recurrence and reinfection remain notably elevated. A heightened HLA-DR + CD8+/CD8+ % is a notable risk factor for HIV/syphilis co-infection and syphilis recurrence/reinfection/serofast state. Therefore, it is advisable to reinforce health education efforts and ensure regular follow-ups for people living with HIV undergoing ART to monitor syphilis infection or increased risk of syphilis infection.

Abstract
Adolescents living with HIV (ALHIV) face unique challenges resulting in persistent treatment gaps, particularly viral non-suppression. Country programs adopt policies, guidelines, and innovations, based on WHO recommendations and best practices from elsewhere. However, it is unclear to what extent these tools address the management of adolescents with viral non-suppression. We report on a review of guidelines for the provision of HIV services to ALHIV in Namibia. We conducted a systematic document review using Content Analysis and Thematic Analysis methodology, and the READ approach. We identified seven relevant policy documents, four of which somewhat addressed viral non-suppression (treatment gap) in ALHIV and outlined interventions to improve treatment outcomes in adolescents considering their lived experience and unique challenges. The persistent treatment gap may reflect policy implementation gaps in specifically addressing viral non-suppression. It may be worthwhile to leverage existing documents to develop specific operational guidance for ALHIV with unsuppressed viral loads.

Abstract
Background Limited data exist on the differential risk of HIV acquisition between infants born preterm versus those born at term to women living with HIV (WLHIV). With a reported increase in preterm delivery among pregnant WLHIV, understanding the risk of vertical transmission of HIV in preterm infants can inform strategies to optimise the timing of diagnostic testing, antiretroviral prophylaxis, and infant feeding. Objectives To describe the prevalence and timing of HIV acquisition, in utero versus perinatal, among infants with perinatal HIV exposure born prior to 37 weeks completed gestation age compared to those born at term in the Botswana-based Mpepu study and explore predictors of infant HIV acquisition. Method Using data extracted from the Mpepu study, we describe the prevalence, timing and risk factors for HIV acquisition in infants born preterm versus those born at term. Fisher exact testing was used to test for differences in prevalence and timing of HIV and a multivariable logistic regression model was used to assess risk factors for infant HIV acquisition. Results 2866 infants born to WLHIV were included in this secondary analysis. 532 (19%) were born preterm. There was no observed difference in the prevalence of HIV acquisition among infants born preterm versus at term overall (0.8% vs 0.6%, P = 0.54), at birth (0.2% vs 0.3%, P = 1.00) or between 14 and 34 days post-delivery (0.6% vs 0.3%, P = 0.41). The absence of maternal antiretroviral use during pregnancy significantly predicted infant HIV acquisition, with the risk of HIV acquisition reduced by 96% among infants whose mothers were taking antiretroviral treatment (ART) during pregnancy (adjusted odds ratio: 0.003, confidence interval: 0.01-0.02, P < 0.001). Conclusion There was no observed increase of in utero and peripartum HIV acquisition among infants born preterm following foetal exposure to HIV compared to those born at term.

Abstract
Background Interferon-inducible protein-10 (IP-10) and monokine induced by interferon-gamma (MIG) are chemokines recognized as inflammatory biomarkers during HIV-1 infection. We assessed their early and long-term dynamics after initiation of antiretroviral treatment (ART). Methods Persons with HIV-1 (PWH) aged>18 years starting their first ART in 2015-2021 in a prospective cohort (n=73) were included. IP-10 and MIG plasma levels were quantified using a multiplexed bead-based assay. Results IP-10 and MIG plasma levels showed a significant and consistent reduction following ART (80% integrase inhibitor [INSTI]-based) initiation, starting at day 20 and maintained throughout the study period (48 months), paralleling the HIV-1 RNA decay and CD4+ count recovery (p<0·001). At baseline, PWH≥ 50 years, CDC stage C and CD4+ count<350cells/mm3 had higher levels of IP-10 (p=0·022, p=0·001 and p=0·002, respectively) and MIG (p<0·001, p=0·024 and p=0·069, respectively). All of them matched their counterparts several months following ART initiation. MIG levels showed a greater decrease at day 10 in those treated with INSTI (p=0·038). Low-level HIV-1 viremia did not impact MIG or IP-10 levels. Conclusion Plasma IP-10 and MIG showed an early significant decline following ART initiation, with greater early declines in MIG levels in INSTI-based regimens. These findings suggest a strong impact of HIV-1 viremia on IP-10 and MIG levels.

Abstract
IRIS is a common complication in HIV-infected patients treated for tuberculosis (TB) and cART. Our aim was to evaluate NK cell reconstitution in HIV-infected patients with TB-IRIS compared to those without IRIS. 147 HIV-infected patients with TB from the CAMELIA trial were enrolled. HIV+TB+ patients were followed for 32 weeks. The NK cell repertoire was assessed in whole blood at different time points. As CAMELIA has two arms (early and late cART initiation), we analysed them separately. At enrolment, individuals had low CD4 cell counts (27 cells/mm3) and high plasma viral loads (5.76 and 5.50 log/mL for IRIS and non-IRIS individuals, respectively). Thirty-seven people developed IRIS (in the early and late arms). In the early and late arms, we observed similar proportions of total NK and NK cell subsets in TB-IRIS and non-IRIS individuals during follow-up, except for the CD56dimCD16pos (both arms) and CD56dimCD16neg (late arm only) subsets, which were higher in TB-IRIS and non-IRIS individuals, respectively, after cART. Regarding the repertoire and markers of NK cells, significant differences (lower expression of NKp30, NKG2A (CD159a), NKG2D (CD314) were observed in TB-IRIS compared to non-IRIS individuals after the start of cART. In the late arm, some changes (increased expression of CD69, NKG2C, CD158i) were observed in TB-IRIS compared to non-IRIS individuals, but only before cART initiation (during TB treatment). KIR expression by NK cells (CD158a and CD158i) was similar in both groups. CD69 expression by NK cells decreased in all groups. Expression of the NCR repertoire (NKp30, NKp44, NKp46) has similar kinetics in TB-IRIS subjects compared to non-IRIS subjects regardless of the arm analysed. NK cell reconstitution appeared to be better in TB-IRIS subjects. Although NK cell reconstitution is impaired in HIV infection after cART, as previously reported, it does not appear to be affected by the development of IRIS in HIV and TB-infected individuals.

Abstract
Objectives Highly active antiretroviral therapy (HAART) has decreased morbidity and mortality among HIV/AIDS-infected patients; however, many patients experience treatment failure. The present study aims to evaluate HIV-infected patients' clinical and immunological profiles with first-line antiretroviral treatment (ART) failure (immunological and clinical) at tertiary care hospitals in Northeast India and explore related treatment failure factors. Methods The hospital-based observational study was conducted among HIV-infected patients with first-line ART failure attending a tertiary care hospital from July 1, 2019, to June 30, 2020. The type of first-line ART failure was defined as a clinical, immunological, or virological failure as decided by the State AIDS Clinical Expert Panel (SACEP) meeting. Data were analyzed with Windows MS Excel (Microsoft Corporation, Redmond, Washington) and Statistical Package for the Social Sciences (SPSS) version 21 (IBM Corp., Armonk, NY). Results Among the 90 HIV-infected patients experiencing first-line ART treatment failure, the majority, 38 (42.2%), were in the age group of 30-40 years, 64 (71.1%) were males, and 70 (77.8%) were of average weight. Tuberculosis was the most typical opportunistic infection, affecting 11 (12.2%) patients. Most patients (38.9%) were initially presented at clinical stage 3. Maximum failures were experienced by patients with baseline CD4 ranging from 100-200 cells/mm3, with 38 (42.2%) patients, and by patients on efavirenz (64.5%) and tenofovir-based regimens (56.6%). Failures occurred more for 24-30 months and were common among patients with adherence below 90%. Conclusion Treatment failure was more common among young male patients and those with normal body mass index (BMI). Low baseline CD4 count and poor adherence were influential in the occurrence of treatment failure. First-line ART failure was higher in tenofovir- and efavirenz-based regimens.

Abstract
BACKGROUND Integrase strand transfer inhibitor-based regimens are recommended for first-line therapy in human immunodeficiency virus type 2 (HIV-2). Nonetheless, dolutegravir (DTG) clinical trial data are lacking. METHODS We conducted a phase 2, single-arm, open-label trial to evaluate the safety and efficacy of a triple therapy regimen that included DTG in persons with HIV-2 (PWHIV-2) in Portugal. Treatment-naive adults receive DTG in combination with 2 nucleoside reverse transcriptase inhibitors (NRTIs). Treatment efficacy was evaluated by the proportion of patients who achieved a plasma viral load (pVL) <40 copies/mL and/or by the change from baseline in CD4+ T-cell count and in CD4/CD8 ratio at week 48. RESULTS A total of 30 patients were enrolled (22 women; median age, 55 years). At baseline, 17 (56.7%) individuals were viremic (median, pVL 190 copies/mL; interquartile range [IQR], 99-445). The median CD4 count was 438 cells/μL (IQR, 335-605), and the CD4/CD8 ratio was 0.8. Three patients discontinued the study. At week 48, all participants (27) had pVL <40 copies/mL. No virological failures were observed. Mean changes in CD4 count and CD4/CD8 ratio at week 48 were 95.59 cells/µL (95% confidence interval [CI], 28-163) and 0.32 (95% CI, .19 to .46). The most common drug-related adverse events were headache and nausea. One participant discontinued due to central nervous system symptoms. No serious adverse events were reported. CONCLUSIONS DTG plus 2 NRTIs is safe and effective as first-line treatment for PWHIV-2 with a tolerability profile previously known. No virological failures were observed that suggest a high potency of DTG in HIV-2 as occurs in HIV-1. CLINICAL TRIALS REGISTRATION M NCT03224338.

Abstract
Endothelial glycocalyx (EG) derangement has been associated with cardiovascular disease (CVD). Studies on EG integrity among people living with HIV (PLWH), are lacking. We conducted a prospective cohort study among treatment-naïve PLWH who received emtricitabine/tenofovir alafenamide, combined with either an integrase strand transfer inhibitor (INSTI, dolutegravir, raltegravir or elvitegravir/cobicistat), or a protease inhibitor (PI, darunavir/cobicistat). We assessed EG at baseline, 24 (±4) and 48 (±4) weeks, by measuring the perfused boundary region (PBR, inversely proportional to EG thickness), in sublingual microvessels. In total, 66 consecutive PLWH (60 (90.9%) males) with a median age (interquartile range, IQR) of 37 (12) years, were enrolled. In total, 40(60.6%) received INSTI-based regimens. The mean (standard deviation) PBR decreased significantly from 2.17 (0.29) μm at baseline to 2.04 (0.26) μm (p = 0.019), and then to 1.93 (0.3) μm (p < 0.0001) at 24 (±4) and 48 (±4) weeks, respectively. PBR did not differ among treatment groups. PLWH on INSTIs had a significant PBR reduction at 48 (±4) weeks. Smokers and PLWH with low levels of viremia experienced the greatest PBR reduction. This study is the first to report the benefit of antiretroviral treatment on EG improvement in treatment-naïve PLWH and depicts a potential bedside biomarker and therapeutic target for CVD in PLWH.

Abstract
PURPOSE OF REVIEW The aim of this study was to provide an overview of the burden, pathogenesis, and recent recommendations for treating hypertension among people living with HIV (PLWH). This review is relevant because of the increase in the prevalence of HIV as a chronic disease and the intersection of the increasing prevalence of hypertension. RECENT FINDINGS The contribution of HIV to the pathogenesis of hypertension is complex and still incompletely understood. Evidence suggests that chronic inflammation from HIV, antiretroviral treatment (ART), and comorbidities such as renal disease and insulin resistance contribute to developing hypertension in PLWH. Treatment is not distinct from guidelines for HIV-noninfected people. Nonpharmacological guidelines such as decreasing blood pressure by promoting a healthy lifestyle emphasizing exercise, weight loss, and smoking cessation are still recommended in the literature. The pharmacological management of hypertension in PLWH is similar, but special attention must be given to specific drugs with potential interaction with ART regimens. Further research is needed to investigate the pathways and effects of hypertension on HIV. SUMMARY There are different pathways to the pathogenesis of hypertension in PLWH. Clinicians should take it into consideration to provide more precise management of hypertension in PLWH. Further research into the subject is still required.

Abstract
Background & objective Human Immunodeficiency Virus (HIV) remains one of the world's most serious health challenges. The development of therapeutic regimens has significantly increased survival and reduced HIV-associated morbidities in HIV-infected individuals. However, some people living with HIV may not respond as expected, resulting in treatment failure. The objective of this study is to identify and characterize, by immunological (T-cell CD4) and virological (viral load) parameters, HIV infected patients with therapeutic failure in Morocco. Methods Prospective cross-sectional studies were conducted over a 5-years period (between January 2015 and December 2019) at the referral center of Ibn Zohr Hospital, Marrakech, Morocco. A total, of 1088 HIV-infected patients diagnosed by the rapid test (Immunochromatography) in addition to Western Blot analysis, was recruited. All patients were under the antiretroviral therapy (ART) for at least six months and followed every six months. Sociodemographic, clinical, and biological data as well as information on patient adherence were collected. Results Out of 1088 patients, 92.46% were under treatment based on non-nucleoside reverse transcriptase inhibitors (NNRTIs) including 26.20% first line first intention and 66.26% first line second intention, and 7.54% of patients on a protease inhibitor (PI) therapy. Regarding the immunological and virological status, 76% of HIV-infected patients had a CD4 count > 200 cells/µl and 24% had a CD4 count < 200 cells / µl, while 69.5% had an undetectable viral load and 30.05% had a detectable viral load (including 11.86% with viral load < 1000 copies / ml and 18.20% viral load > 1000 copies / ml) (P-values < 0.05). Conclusion In our study, we showed a therapeutic failure rate of 18.2% in HIV-infected patients under treatment in Marrakech region. These failures were mainly related to poor adherence and low CD4+ rates at the initiation of treatment. We concluded that immunological monitoring alone is insufficient to predict virological suppression and therapeutic success. Consequently, we recommend the HIV plasma viral load test be accessible as a routine exam.

Abstract
HIV-HBV coinfected patients have higher rates of liver-related morbidity, hospitalizations, and mortality compared to HBV or HIV mono-infected ones. Clinical studies have shown an accelerated progression of liver fibrosis and an increased incidence of HCC, resulting from the combined action of HBV replication, immune-mediated hepatocytolysis, and HIV-induced immunosuppression and immunosenescence. Antiviral therapy based on dually active antiretrovirals is highly efficient, but late initiation, global disparities in accessibility, suboptimal regimens, and adherence issues may limit its impact on the development of end-stage liver disease. In this paper, we review the mechanisms of liver injuries in HIV-HBV coinfected patients and the novel biomarkers that can be used for treatment monitoring in HIV-HBV coinfected persons: markers that assess viral suppression, markers for liver fibrosis evaluation, and predictors of oncogenesis.

Abstract
OBJECTIVE To establish a potential relationship between hypertensive disorders of pregnancy (HDP) and HIV infection. METHODS This cross-sectional observational study involving 300 women with HDP was undertaken from September 2018 to February 2019 in a regional hospital in Durban, South Africa, a setting with a background HIV prevalence of 45% among pregnant women. All women with new-onset elevation of blood pressure after the 20th week of pregnancy were enrolled and, following informed consent, the relevant information was extracted from their files. RESULTS Of the 300 women with HDP, the HIV prevalence was 30%, compared with the historical seroprevalence of 45% within the hospital (P = 0.028). For all categories of HDP, there were fewer primigravid women among women living with HIV (WLHIV), compared with those uninfected (30% vs 50.2%, respectively; P = 0.001). HDP developed later in gestation in WLHIV compared with uninfected women (32.6 weeks vs 34 weeks, respectively; P = 0.023), however, there were significant maternal complications of abruption and elevated liver enzymes among WLHIV (P = 0.02 and P = 0.014, respectively). Despite this, the perinatal outcomes were similar in both groups. CONCLUSION HIV or its treatment seems to have a protective effect in the development of HDP; however, the complications of HDP may be significant in WLHIV receiving treatment.

Abstract
BACKGROUND We evaluated trends in CD4/CD8 ratio among people living with HIV (PLWH) starting antiretroviral therapy (ART) with first-line integrase strand transfer inhibitors (INSTI) compared with non-INSTI-based ART, and the incidence of CD4/CD8 ratio normalization. METHODS All PLWH enrolled in adult HIV cohorts of IeDEA Asia-Pacific who started with triple-ART with at least 1 CD4, CD8 (3-month window), and HIV-1 RNA measurement post-ART were included. CD4/CD8 ratio normalization was defined as a ratio ≥1. Longitudinal changes in CD4/CD8 ratio were analyzed by linear mixed model, the incidence of the normalization by Cox regression, and the differences in ratio recovery by group-based trajectory modeling. RESULTS A total of 5529 PLWH were included; 80% male, median age 35 years (interquartile range [IQR], 29-43). First-line regimens were comprised of 65% NNRTI, 19% PI, and 16% INSTI. The baseline CD4/CD8 ratio was 0.19 (IQR, 0.09-0.33). PLWH starting with NNRTI- (P = 0.005) or PI-based ART (P = 0.030) had lower CD4/CD8 recovery over 5 years compared with INSTI. During 24,304 person-years of follow-up, 32% had CD4/CD8 ratio normalization. After adjusting for age, sex, baseline CD4, HIV-1 RNA, HCV, and year of ART initiation, PLWH started with INSTI had higher odds of achieving CD4/CD8 ratio normalization than NNRTI- (P < 0.001) or PI-based ART (P = 0.015). In group-based trajectory modeling analysis, INSTI was associated with greater odds of being in the higher ratio trajectory. CONCLUSIONS INSTI use was associated with higher rates of CD4/CD8 ratio recovery and normalization in our cohort. These results emphasize the relative benefits of INSTI-based ART for immune restoration.

Abstract
Nationally representative surveys provide an opportunity to assess trends in recent human immunodeficiency virus (HIV) infection based on assays for recent HIV infection. We assessed HIV incidence in Kenya in 2018 and trends in recent HIV infection among adolescents and adults in Kenya using nationally representative household surveys conducted in 2007, 2012, and 2018. To assess trends, we defined a recent HIV infection testing algorithm (RITA) that classified as recently infected (<12 months) those HIV-positive participants that were recent on the HIV-1 limiting antigen (LAg)-avidity assay without evidence of antiretroviral use. We assessed factors associated with recent and long-term (≥12 months) HIV infection versus no infection using a multinomial logit model while accounting for complex survey design. Of 1,523 HIV-positive participants in 2018, 11 were classified as recent. Annual HIV incidence was 0.14% in 2018 [95% confidence interval (CI) 0.057-0.23], representing 35,900 (95% CI 16,300-55,600) new infections per year in Kenya among persons aged 15-64 years. The percentage of HIV infections that were determined to be recent was similar in 2007 and 2012 but fell significantly from 2012 to 2018 [adjusted odds ratio (aOR) = 0.31, p < .001]. Compared to no HIV infection, being aged 25-34 versus 35-64 years (aOR = 4.2, 95% CI 1.4-13), having more lifetime sex partners (aOR = 5.2, 95% CI 1.6-17 for 2-3 partners and aOR = 8.6, 95% CI 2.8-26 for ≥4 partners vs. 0-1 partners), and never having tested for HIV (aOR = 4.1, 95% CI 1.5-11) were independently associated with recent HIV infection. Although HIV remains a public health priority in Kenya, HIV incidence estimates and trends in recent HIV infection support a significant decrease in new HIV infections from 2012 to 2018, a period of rapid expansion in HIV diagnosis, prevention, and treatment.

Abstract
BACKGROUND The extent of immune reconstitution in human immunodeficiency virus (HIV) infected persons receiving long-term antiretroviral therapy (ART) with controlled viral load has been controversial. We studied the extent and speed of T cell subsets retrieval after long-term antiretroviral treatment. METHODS 662 HIV-infected patients followed at least 2 years whose plasma HIV-1 RNA load <50 copies/mL were evaluated for longitudinal and functional phenotypic indices of immune restoration. Determinants of change in magnitude and importance of recovery have been evaluated using mixed linear regression models. RESULTS Almost all robust immune restorations achieved occurred after 2-3 years of ART. The median CD4 lymphocyte count increased 449 cells/μl (IQR 303-604) from 226 cells/μl (IQR 83-336) at baseline during the third year (P < 0.001); CD4+T lymphocyte rises during the sixth and tenth years were not significant. Naive and memory CD4+T cells'reconstitution occurred in the sixth and eighth years of ART but no significant change thereafter. The change of CD45RA+Naïve and CD45RA-memory CD4+T cell reconstitution is different in baseline CD4+T cell counts <100 cells/μl group and in baseline CD4+T cell counts >100 cells/μl group. Activation antigen expression (CD38 or HLA-DR) on CD8 lymphocytes declined mostly during the first till second year, and after 4 years, activation antigen expression on patient lymphocytes showed no significant change. The proportion of CD4 cells expressing CD28 climbed during the first years and reached normal levels in the second year. CONCLUSIONS Immune restoration was dependent on the capacity of immune system during the first 2-3 year of ART. But the significant change of CD4 and compartments of CD4+T cells could persist until 6-8 years. The pattern of CD38+CD8+, HLA-DR+CD8+, CD28+CD4+ T cells could quickly return to normal level and no significant change after sufficient time of ART. In general, the immune response compared to the baseline status may be the overall effect from the age and time of antiretroviral treatment.

Abstract
BACKGROUND Age-associated comorbidities are higher in people with HIV (PWH) than HIV-negative individuals. This is partially attributed to immune activation and CD38 expression on T cells driving chronic inflammation. However, the exact contribution of CD38-expressing T cells on the proinflammatory response is not completely understood. METHODS CD38-expressing CD8 + T lymphocytes were measured from PWH and HIV-negative individuals. Mitochondrial mass, superoxide content, membrane depolarization of CD4 + and CD8 + T lymphocytes, and cytokine production after HIV(Gag)-specific peptide stimulation from CD38 + CD8 + T lymphocytes of PWH were measured to link biological effects of CD38 expression on cellular metabolism. RESULTS The frequency of activated CD8 + CD38 + T cells persists in PWH on ART compared with HIV-negative individuals. Higher CD38 expression is associated with mitochondrial biogenesis and HIV(Gag)-specific proinflammatory cytokine production in PWH. Blockade of CD38 results in lower Gag-specific cytokine production. CONCLUSIONS ART only partially reduced HIV-induced CD38 expression on CD8 + T cells. CD8 + CD38 + T cells are highly activated in vivo, and HIV-specific stimulation in vitro augments CD38 expression, contributing to a proinflammatory response despite virologic control with ART. Therefore, CD38 is a potential therapeutic target for mitigating chronic inflammation that likely drives cellular aging, comorbidities, and end-organ disease in PWH.

Abstract
INTRODUCTION Standard-of-care antiretroviral treatment (ART) monitoring in low and middle-income countries consists of annual determination of HIV-RNA viral load with confirmatory viral load testing in case of viral rebound. We evaluated an intensified monitoring strategy of three-monthly viral load testing with additional drug exposure and drug resistance testing in case of viral rebound. METHODS We performed an open-label randomized controlled trial (RCT) at a rural South African healthcare clinic, enrolling adults already receiving or newly initiating first-line ART. During 96 weeks follow-up, intervention participants received three-monthly viral load testing and sequential point-of-care drug exposure testing and DBS-based drug resistance testing in case of rebound above 1000 copies/ml. Control participants received standard-of-care monitoring according to the WHO guidelines. RESULTS Five hundred one participants were included, of whom 416 (83.0%) were randomized at 24 weeks. Four hundred one participants were available for intention-to-treat analysis. Viral rebound occurred in 9.0% (18/199) of intervention participants and in 11.9% (24/202) of controls ( P = 0.445). Time to detection of rebound was 375 days [interquartile range (IQR): 348-515] in intervention participants and 360 days [IQR: 338-464] in controls [hazard ratio: 0.88 (95% confidence interval (95% CI): 0.46-1.66]; P = 0.683]. Duration of viral rebound was 87 days [IQR: 70-110] in intervention participants and 101 days [IQR: 78-213] in controls ( P = 0.423). In the control arm, three patients with confirmed failure were switched to second-line ART. In the intervention arm, of three patients with confirmed failure, switch could initially be avoided in two cases. CONCLUSION Three-monthly viral load testing did not significantly reduce the duration of viraemia when compared with standard-of-care annual viral load testing, providing randomized trial evidence in support of annual viral load monitoring.

Abstract
INTRODUCTION Few clinical trials and cohort studies have evaluated the efficacy of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in people with HIV (PWH) with preexisting M184V/I or other nucleos(t)ide reverse transcriptase inhibitor (NRTI) resistance-associated mutations (RAMs). Real-world data are also scarce. METHODS Retrospective review of treatment-experienced patients who started B/F/TAF in a cohort of PWH. HIV-RNA less than 50 copies/ml was analyzed at 48 weeks in an intention-to-treat (ITT) analysis (missing=failure) and per protocol analysis (patients with missing data or changes for reasons other than virological failure were excluded). Results were compared in patients with and without previous NRTI-RAMs. RESULTS Five hundred and six PWH were included (16.2% women). Median age and time with HIV infection were 52.3 and 18.9 years, respectively. At baseline, viral load was less than 50 copies/ml in 440 patients (86.6%). Overall, 69 (13.6%) participants had documented preexisting NRTI-RAMs: 57 (11.2%) M184V/I and 30 (5.9%) tenofovir RAMs. In the ITT analysis, 83% (420/506) had HIV-RNA less than 50 copies/ml [82.2% (359/437) and 88.4% (61/69) in persons without and with NRTI-RAMs, respectively ( P = 0.2)]. In the per protocol analysis 94.2% (420/445) had HIV-RNA less than 50 copies/ml [94.4% (359/380) vs. 93.8% (61/65); P = 0.2]. A total of 61 participants were excluded from the per protocol analysis (23 missing data, 19 discontinued B/F/TAF because of toxicity, 13 for other reasons, and 6 died). CONCLUSION Switching to B/F/TAF is well tolerated and effective in the real-world setting, even in patients with preexisting NRTI RAMs, such as M184V and RAMs conferring resistance to tenofovir. These results confirm the robustness of this combination.

Abstract
OBJECTIVES We estimate the effects of ATLAS's HIV self-testing (HIVST) kit distribution on conventional HIV testing, diagnoses, and antiretroviral treatment (ART) initiations in Côte d'Ivoire. DESIGN Ecological study using routinely collected HIV testing services program data. METHODS We used the ATLAS's programmatic data recorded between the third quarter of 2019 and the first quarter of 2021, in addition to data from the President's Emergency Plan for AIDS Relief dashboard. We performed ecological time series regression using linear mixed models. Results are presented per 1000 HIVST kits distributed through ATLAS. RESULTS We found a negative but nonsignificant effect of the number of ATLAS' distributed HIVST kits on conventional testing uptake (-190 conventional tests; 95% confidence interval [CI]: -427 to 37). The relationship between the number of HIVST kits and HIV diagnoses was significant and positive (+8 diagnosis; 95% CI: 0 to 15). No effect was observed on ART initiation (-2 ART initiations; 95% CI: -8 to 5). CONCLUSIONS ATLAS' HIVST kit distribution had a positive impact on HIV diagnoses. Despite the negative signal on conventional testing, even if only 20% of distributed kits are used, HIVST would increase access to testing. The methodology used in this paper offers a promising way to leverage routinely collected programmatic data to estimate the effects of HIVST kit distribution in real-world programs.

Abstract
Background The coronavirus disease 2019 (COVID-19) pandemic resulted in unique programmatic opportunities to test hypotheses related to the initiation of antiretroviral treatment (ART) and viral load (VL) suppression during a global health crisis, which would not otherwise have been possible. Objectives To generate practice-relevant evidence on the impact of initiating ART pre-COVID-19 versus during the COVID-19 pandemic on HIV VL. Method Logistic regression was performed on data covering 6596 persons with HIV whose VL data were available, out of 36 585 persons who were initiated on ART between 01 April 2019 and 30 March 2021. Results After controlling for covariates such as age, gender, duration on ART, tuberculosis status at the time of the last visit, and rural vs urban status, the odds of having a VL < 1000 copies/mL were significantly higher for clients who started ART during the COVID-19 pandemic than the year before COVID-19 (adjusted odds ratio [AOR]: 2.50; confidence interval [CI]: 1.55–4.01; P < 0.001). Odds of having a VL < 1000 copies/mL were also significantly higher among female participants than male (AOR: 1.23; CI: 1.02–1.48), among patients attending rural clinics compared to those attending urban clinics (AOR: 1.83; CI: 1.47–2.28), and in clients who were 15 years or older at the time of their last visit (AOR: 1.50; CI: 1.07–2.11). Conclusion Viral loads did not deteriorate despite pandemic-induced changes in HIV services such as the expansion of multi-month dispensing (MMD), which may have played a protective role regardless of the general negative impacts of response to the COVID-19 crises on communities and individuals. What this study adds This research capitalises on the natural experiment of COVID-19-related changes in HIV services and provides new practice-relevant research evidence.

Abstract
OBJECTIVE To assess disruption in healthcare services for HIV treatment by national emergency in response to the coronavirus disease 2019 (COVID-19) pandemic in the United States. DESIGN Time-series analysis. METHODS We analyzed the IQVIA Real World Data-Longitudinal Prescriptions Database and calculated time trends in the weekly number of persons with active antiretroviral prescriptions for HIV treatment, and of persons who obtained antiretroviral prescriptions during January 2017-March 2021. We used interrupted time-series models to estimate the impact of the COVID-19 pandemic on antiretroviral therapy (ART) use between March 2020 and March 2021. RESULTS We found that the weekly number of persons with active antiretroviral prescriptions decreased by an average 2.5% (95% confidence interval [CI]: -3.8% to -1.1%), compared to predicted use, during March 2020 through March 2021. The weekly number of persons who obtained antiretroviral prescriptions decreased 4.5% (95% CI: -6.0% to -3.0%), compared to the predicted number. Men, persons aged ≤34 years, privately insured persons, and persons in medication assistance programs had greater decreases than other groups. CONCLUSIONS We demonstrated a decrease in the number of persons with active antiretroviral prescriptions during the first year of the COVID-19 pandemic and the number did not return to levels expected in the absence of the pandemic. Disruptions in HIV care and decreased ART may lead to lower levels of viral suppression and immunologic control, and increased HIV transmission in the community.

Abstract
Antiretroviral therapy (ART) uptake continues to increase across sub-Saharan Africa and emergence of drug-resistant HIV mutations poses significant challenges to management of treatment-experienced patients with virologic failure. In Zambia, new third-line ART (TLART) guidelines including use of dolutegravir (DTG) were introduced in 2018. We assessed virologic suppression, immunologic response, and HIV drug-resistant mutations (DRMs) among patients on TLART at the University Teaching Hospital (UTH) in Lusaka, Zambia. We conducted a retrospective review of patients enrolled at UTH on TLART for >6 months between January 2010 and June 30, 2021. CD4 and HIV viral load (VL) at TLART initiation and post-initiation were assessed to determine virologic and immunologic outcomes. Regression analysis using bivariate and multivariate methods to describe baseline characteristics, virologic, and immunologic response to TLART was performed. A total of 345 patients met inclusion criteria; women comprised 57.6% (199/345) of the cohort. Median age at HIV diagnosis was 30 (interquartile range: 17.3-36.8). In 255 (73.8%) patients with at least two VLs, VL decreased from mean of 3.45 log10 copies/mL (standard deviation [SD]: 2.02) to 1.68 log10 copies/mL (SD: 1.79). Common ARVs prescribed included DTG (89.9%), tenofovir disoproxil fumarate (68.7%), and darunavir boosted with ritonavir (66.4%); 170 (49.3%) patients had genotypes; mutations consisted of 88.8% nucleoside reverse transcriptase inhibitor, 86.5% non-nucleoside reverse transcriptase inhibitor, and 55.9% protease inhibitor. VL suppression to <1,000 copies/mL was achieved in 225 (78.9%) patients. DRM frequency ranged from 56% to 89% depending on drug class. Treatment-experienced patients receiving TLART in Zambia achieved high rates of suppression despite high proportions of HIV mutations illustrating TLART effectiveness in the DTG era.

Abstract
Background Pragmatic clinical trials generally rely on real world data and have the potential to generate real world evidence. This approach arose from concerns that many trial results did not adequately inform real world practice. However, maintaining the real world setting during the conduct of a trial and ensuring adequate protection for research participants can be challenging. Best practices in research oversight for pragmatic clinical trials are nascent and underdeveloped, especially in developing countries. Methods We use the PRECIS-2 tool to present a case study from Lilongwe in Malawi to describe ethical and regulatory challenges encountered during the conduct of a pragmatic trial and suggest possible solutions. Results In this article, we highlight the following six issues: (1) one public facility hosting several pragmatic trials within the same period; (2) research participants refusing financial incentives; (3) inadequate infrastructure and high workload to conduct research; (4) silos among partner organisations involved in delivery of health care; (5) individuals influencing the implementation of revised national guidelines; (6) difficulties with access to electronic medical records. Conclusion Multiple stakeholder engagement is critical to the conduct of pragmatic trials, and even with careful stakeholder engagement, continuous monitoring by gatekeepers is essential. In the Malawian context, active engagement of the district research committees can complement the work of the research ethics committees (RECs).

Abstract
Objective In the determination and monitoring of neurocognitive disorders in human immunodeficiency virus (HIV)-positive individuals, there is a need for significantly more practical methods which provide results in a shorter time than the tests that require challenging and specialized expertise. This study aimed to evaluate cognitive functions and the factors affecting them in naïve HIV-positive patients using by Montreal Cognitive Assessment (MoCA) test before and after the initiation of combination antiretroviral therapy. Materials and Methods HIV-positive, treatment-naïve patients monitored between January-June 2017 were included in the study. The MoCA test was performed at the beginning and the sixth month of the treatment. Results Forty male patients were included in the study. The mean age was calculated as 29.1±4.0. When the factors affecting the MoCA score were examined, there was a significant relationship between the education level and the MoCA score. Smoking, using alcohol, and substance did not have a significant impact on baseline MoCA values. A significant correlation was found between cluster differentiation 4 (CD4) count and HIV RNA level and attention function. There was a significant increase in the total MoCA score and the MoCA subgroup scores at the end of the sixth month of the treatment. Conclusion MoCA test is one of the most practical tests that can be applied in a short time period, and it was found useful in evaluating the changes in the cognitive functions of HIV-positive patients during antiretroviral treatment.

Abstract
Introduction With virologic suppression and longer life expectancy, older adults with HIV (OAHIV) are at risk for neurocognitive impairment (NCI). This study investigated neurocognitive performance, quality of life (QOL) and the association between OAHIV determinants. Methods This cross‐sectional study was conducted in OAHIV aged ≥ 50 years on antiretroviral treatment at community hospitals in Northern Thailand between September and November 2020. The Montreal Cognitive Assessment Thai Version (MoCA‐T) and the Thai‐validated Medical Outcomes Study HIV (MOS‐HIV) were used. NCI was defined as MoCA‐T scores <25: 16–24 for amnestic mild cognitive impairment (aMCI) and <16 for dementia. For QOL, higher scores meant better QOL; a physical health summary T‐score ≥50 was defined as good QOL. Results Overall, 269 OAHIV were enrolled; 59% were female and 99% had virologic suppression. The current median age was 61.8 years (interquartile range [IQR] 58.9–65.7). The median duration of antiretroviral treatment was 10.5 years (IQR 8.5–13.5). The current median CD4 count (234 tested) was 484 cells/mm3 (IQR 339–634), and 99% had plasma HIV RNA <40 copies/ml (229 tested). The median MoCA‐T score was 20.0 (IQR 16.3–23.0). There were 234 OAHIV (87.3%) with NCI: 182 (67.9%) with aMCI and 52 (19.4%) with dementia. A hundred and ninety (70.6%) had good QOL. Bivariate analysis revealed no correlation between MoCA‐T scores and QOL. Multivariable linear regression analysis revealed that MoCA‐T score was associated with older age (r = –0.144, p = 0.002), lower education (r = 0.629, p < 0.001), lower income (r = 0.797, p = 0.040) and shorter treatment duration (r = 0.189, p = 0.006). Conclusions The vast majority of OAHIV with virologic suppression had NCI. Approximately two‐thirds had a mild impairment and one‐fifth had dementia. Neurocognitive performance and QOL were not correlated. Addressing mild NCI would enable more targeted monitoring. Early intervention and support could minimize functional impairment with increased age.

Abstract
BACKGROUND The European AIDS Clinical Society (EACS) Guidelines were revised in 2021 for the 17th time with updates on all aspects of HIV care. KEY POINTS OF THE GUIDELINES UPDATE Version 11.0 of the Guidelines recommend six first-line treatment options for antiretroviral treatment (ART)-naïve adults: tenofovir-based backbone plus an unboosted integrase inhibitor or plus doravirine; abacavir/lamivudine plus dolutegravir; or dual therapy with lamivudine or emtricitabine plus dolutegravir. Recommendations on preferred and alternative first-line combinations from birth to adolescence were included in the new paediatric section made with Penta. Long-acting cabotegravir plus rilpivirine was included as a switch option and, along with fostemsavir, was added to all drug-drug interaction (DDI) tables. Four new DDI tables for anti-tuberculosis drugs, anxiolytics, hormone replacement therapy and COVID-19 therapies were introduced, as well as guidance on screening and management of anxiety disorders, transgender health, sexual health for women and menopause. The sections on frailty, obesity and cancer were expanded, and recommendations for the management of people with diabetes and cardiovascular disease risk were revised extensively. Treatment of recently acquired hepatitis C is recommended with ongoing risk behaviour to reduce transmission. Bulevirtide was included as a treatment option for the hepatitis Delta virus. Drug-resistant tuberculosis guidance was adjusted in accordance with the 2020 World Health Organization recommendations. Finally, there is new guidance on COVID-19 management with a focus on continuance of HIV care. CONCLUSIONS In 2021, the EACS Guidelines were updated extensively and broadened to include new sections. The recommendations are available as a free app, in interactive web format and as an online pdf.

Abstract
Objective: The primary endpoint of the study was to determine the proportion of patients with HIV RNA < 50 copies/mL at 48 weeks. Design: Phase IV, multicentric, open-label, single-arm clinical trial of participants recruited in 2018−2019 to evaluate the efficacy and safety of tenofovir alafenamide/emtricitabine/elvitegravir-cobicistat (TAF/FTC/EVG-c) as first-line treatment in HIV-1 infected naïve participants with advanced disease. Methods: Adverse events were graded according to the Division of AIDS scale version 2.0. Quantitative variables were recorded as median and interquartile range, and qualitative variables as absolute number and percentage. T-Student or Wilcoxon tests were used to analyze intragroup differences of the continuous variables. Results: Fifty participants were recruited with a baseline median CD4 lymphocyte count of 116 cells/µL and a viral load of 218,938 copies/mL. The proportion of patients with viral load <50 copies/mL at week 48 was 94% in the per-protocol analysis, with a median time of 1.9 months to achieve it. Three adverse events attributed to the study drug caused trial discontinuation. Conclusions: the use of TAF/FTC/EVG-c in patients with advanced HIV disease in our study demonstrated efficacy comparable to data from pivotal clinical trials with a good safety profile.

Abstract
BACKGROUND Human immunodeficiency virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS) is a public health issue of global importance. To our knowledge, no previous meta-analysis documenting the prevalence, socio-demographic, and service use determinants associated with HIV/AIDS disclosure to infected children has been conducted. The present study aimed to determine the prevalence, socio-demographics and service use determinants associated with the disclosure of HIV/AIDS status to infected children. METHODS Studies in English published between 01 January 1985 and 01 November 2021, and available on PubMed, Scopus, Web of Science, and Cochrane electronic databases were searched. After reviewing for study duplicates, the full-text of selected articles were assessed for eligibility using Population, Intervention, Comparator, Outcomes (PICO) criteria. We used fixed and random-effects meta-analysis models to estimate the pooled prevalence, pooled odds ratio (OR), and 95% confidence intervals. RESULTS After article duplicates were excluded, assessments of abstracts were completed, and full-text papers evaluated, 37 studies were included in this meta-analysis. The prevalence of the disclosure of HIV status to children was measured to be 41% in this research. The odds that a child of 10 years and older is informed that they are HIV-positive is 3.01 time the odds that younger children are informed. Those children who had primary or lower schooling level were 2.41 times more likely to be informed of their HIV-positive status than children with higher levels of schooling. Children who had a non-biological parents were 3.17 times more likely to have been disclose being HIV-positive; social support (OR = 8.29, 95%CI = 2.34, 29.42), children who had higher levels of social supports were 8.29 times more likely to disclose HIV-positive; the primary educational level of caregivers (OR = 2.03, 95%CI = 1.43, 2.89), respondents who had caregivers with primary education level were 2.03 times more likely to disclose HIV-positive; antiretroviral treatment (ART) adherence (OR = 2.59, 95%CI = 1.96, 3.42), participants who adhered to ART were 2.59 times more likely to disclose HIV-positive and hospital follow-up (OR = 2.82, 95%CI = 1.85, 4.29), those who had hospital follow-up were 2.82 times more likely to disclose HIV-positive; were all significantly associated with the disclosure of HIV/AIDS status to infected children. CONCLUSION Such data are of importance for healthcare pediatrics HIV care professionals. Facilitating HIV diagnosis and disclosure to the infected children and ensuring access to HIV treatment will likely prevent secondary HIV transmission. Healthcare professionals are expected to provide age-appropriate counseling services to this population.

Abstract
Objectives International lockdowns during the COVID‐19 pandemic impacted antiretroviral drug supplies in Indonesia. We assessed the impact of antiretroviral treatment (ART) provision and being lost to follow‐up (LTFU) on people living with HIV, attending a key population‐focused HIV clinic in Denpasar, Bali. Methods This was a retrospective note review of anonymized data from adult Indonesian patients living with HIV. We collected demographic data and information on being LTFU, and assessed the numbers of patients impacted by ART switches from fixed‐dose combination (FDC) tenofovir/lamivudine/efavirenz to multi‐pill zidovudine‐based regimens, during the first international lockdown from March 2020. Results Records of 260 Indonesian adult patients registered for HIV care and prescribed ART were reviewed; 240 (92.3%) were men, and 90% were men who have sex with men. Between 13 March and 28 May 2020, 214 (87%) out of 247 patients (previously diagnosed with HIV) had to switch to individual, multi‐pill zidovudine‐based regimens from their FDC. The switch lasted a mean of 35 days (range 10–85). Twenty‐five patients (10%) were LTFU; patients who switched were more likely to remain in care. Data on viral load status and toxicity are lacking as laboratory testing requires self‐payment. Conclusions The majority of patients living with HIV had no choice but to switch to multi‐pill, zidovudine‐based regimens. Despite significant efforts to minimize the impact of lockdown on care, 10% of patients were LTFU. Patients switching ART required greater clinic attention and support, improving retention. Complete national data are needed to understand the impact of ART stockouts on virological suppression and drug resistance throughout Indonesia.

Abstract
OBJECTIVES Antiretroviral treatment (ART) is essential in preventing mother-to-child transmission of human immunodeficiency virus (HIV), and postpartum discontinuation of ART is associated with adverse outcomes. This study identified factors associated with postpartum follow-up of HIV-positive women. METHODS This was a retrospective cohort study of 170 HIV-infected pregnant women who received regular obstetric examination and delivered successfully in Beijing between 2003 and 2020.The women's sociodemographic, clinical, treatment, obstetric, and gestational characteristics were analyzed. Cox proportional hazards models were used to estimate adjusted hazard ratios (AHRs) of loss to follow-up between levels of confounders. RESULTS In the multivariable Cox proportional hazard models, women with a longer time from HIV diagnosis to delivery per year had a 1.4-timeshigher risk (AHR = 1.433, 95% CI: 0.897-2.229) and a higher rate of loss to follow-up than the other women. Perinatal health care (AHR = 0.003,95% CI: 0.000-0.105) and gestational age above 37 weeks at delivery (AHR = 0.294, 95% CI: 0.005-15.818) were associated with a longer follow-up of postpartum HIV-positive women, when compared to women who did not receive perinatal healthcare and who delivered before 37 weeks of gestation, respectively. CONCLUSIONS The longer time from HIV diagnosis to delivery, access to perinatal care, and full-term gestation at delivery improved postpartum ART adherence and follow-up among HIV-positive women. Early initiation of ART, integration of adult ART into prevention of mother-to-child transmission, combination ART with maternal healthcare, and enhanced pregnancy care will improve ART adherence among HIV-positive women after delivery.

Abstract
HIV-infected people have started to live longer since the introduction of antiretroviral therapy, however various co-morbid illnesses have emerged. Three HIV-infected individuals, all at least 43 years old, reported with a new onset of type 2 diabetes after switching to dolutegravir-combined antiretroviral therapy regimen. These three people were switched to integrase strand transfer inhibitor (dolutegravir)-based first-line antiretroviral treatment after receiving non-nucleoside reverse transcriptase inhibitor-combined first-line antiretroviral treatment for at least 6 years, as recommended by the World Health Organization for Sub-Saharan African countries, including Ethiopia.All of the given cases had normal plasma fasting sugar (fasting blood sugar <100 mg/dL) at the time of switching. Polyuria, polydipsia, considerable weight loss, and fatigue were all classified as signs of diabetes mellitus in the two male cases. In addition, their laboratory results demonstrated hyperglycemia (plasma fasting blood sugar > 200 mg/dL and urine glucose level ⩾2+) with no ketonuria after switching to dolutegravir for 4–10 months. A glycemic control was achieved, and metformin medication was continued. After 6 months of dolutegravir treatment, the third female case developed diabetic ketoacidosis and severe hyperglycemia (fasting blood glucose level 600 mg/dL, urine glucose level 3+, and ketonuria 3+). To recover from diabetic ketoacidosis, the patient was given intravenous normal saline and regular insulin. Her glycemic control was then restored, and she was switched to NPH insulin. For all of the cases presented, the dolutegravir-based regimen was maintained. Antiretroviral regimens using dolutegravir have the potential to cause hyperglycemia and other side effects. As a result, blood glucose monitoring is required throughout treatment initiation and regularly throughout treatment follow-up, particularly for those on dolutegravir-combined antiretroviral therapy regimens.

Abstract
HIV-1-infected cells that persist despite antiretroviral therapy (ART) are frequently considered "transcriptionally silent," but active viral gene expression may occur in some cells, challenging the concept of viral latency. Applying an assay for profiling the transcriptional activity and the chromosomal locations of individual proviruses, we describe a global genomic and epigenetic map of transcriptionally active and silent proviral species and evaluate their longitudinal evolution in persons receiving suppressive ART. Using genome-wide epigenetic reference data, we show that proviral transcriptional activity is associated with activating epigenetic chromatin features in linear proximity of integration sites and in their inter- and intrachromosomal contact regions. Transcriptionally active proviruses were actively selected against during prolonged ART; however, this pattern was violated by large clones of virally infected cells that may outcompete negative selection forces through elevated intrinsic proliferative activity. Our results suggest that transcriptionally active proviruses are dynamically evolving under selection pressure by host factors.

Abstract
People living with HIV (PLWH) require life-long anti-retroviral treatment and often present with comorbidities such as metabolic syndrome (MetS). Systematic lipidomic characterization and its association with the metabolism are currently missing. We included 100 PLWH with MetS and 100 without MetS from the Copenhagen Comorbidity in HIV Infection (COCOMO) cohort to examine whether and how lipidome profiles are associated with MetS in PLWH. We combined several standard biostatistical, machine learning, and network analysis techniques to investigate the lipidome systematically and comprehensively and its association with clinical parameters. Additionally, we generated weighted lipid-metabolite networks to understand the relationship between lipidomic profiles with those metabolites associated with MetS in PLWH. The lipidomic dataset consisted of 917 lipid species including 602 glycerolipids, 228 glycerophospholipids, 61 sphingolipids, and 26 steroids. With a consensus approach using four different statistical and machine learning methods, we observed 13 differentially abundant lipids between PLWH without MetS and PLWH with MetS, which mainly belongs to diacylglyceride (DAG, n = 2) and triacylglyceride (TAG, n = 11). The comprehensive network integration of the lipidomics and metabolomics data suggested interactions between specific glycerolipids' structural composition patterns and key metabolites involved in glutamate metabolism. Further integration of the clinical data with metabolomics and lipidomics resulted in the association of visceral adipose tissue (VAT) and exposure to earlier generations of antiretroviral therapy (ART). Our integrative omics data indicated disruption of glutamate and fatty acid metabolism, suggesting their involvement in the pathogenesis of PLWH with MetS. Alterations in the lipid homeostasis and glutaminolysis need clinical interventions to prevent accelerated aging in PLWH with MetS.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is strongly associated with the metabolic syndrome and is one of the most prevalent comorbidities in HIV and HBV infected patients. HIV plays an early and direct role in the development of metabolic syndrome by disrupting the mechanism of adipogenesis and synthesis of adipokines. Adipokines, molecules that regulate the lipid metabolism, also contribute to the progression of NAFLD either directly or via hepatic organokines (hepatokines). Most hepatokines play a direct role in lipid homeostasis and liver inflammation but their role in the evolution of NAFLD is not well defined. The role of HBV in the pathogenesis of NAFLD is controversial. HBV has been previously associated with a decreased level of triglycerides and with a protective role against the development of steatosis and metabolic syndrome. At the same time HBV displays a high fibrogenetic and oncogenetic potential. In the HIV/HBV co-infection, the metabolic changes are initiated by mitochondrial dysfunction as well as by the fatty overload of the liver, two interconnected mechanisms. The evolution of NAFLD is further perpetuated by the inflammatory response to these viral agents and by the variable toxicity of the antiretroviral therapy. The current article discusses the pathogenic changes and the contribution of the hepatokine/adipokine axis in the development of NAFLD as well as the implications of HIV and HBV infection in the breakdown of the hepatokine/adipokine axis and NAFLD progression.

Abstract
Objectives Pill count is used to assess drug adherence in people living with HIV (PLHIV). Carrying a pillbox is associated with fear of concealment and stigma and might indicate poor adherence and predict someone who will be lost to follow‐up (LTFU). We therefore assessed the association between pillbox return and being LTFU in rural Tanzania. Methods This is a nested study of the Kilombero and Ulanga Antiretroviral Cohort (KIULARCO). We included PLHIV aged ≥ 18 years enrolled in KIULARCO between January 2013 and March 2019 with follow‐up through January 2020, who were on antiretroviral treatment (ART) for ≥ 6 months. Baseline was defined as the latest ART initiation or KIULARCO enrolment. We determined the association between time‐dependent failed pillbox return updated at every visit and LTFU using Kaplan–Meier estimation and Cox models. Results Among 2552 PLHIV included in the study, 1735 (68.0%) were female, 959 (40.3%) had a WHO stage III/IV and 1487 (66.4%) had a CD4 cell count < 350 cells/µL. The median age was 38.4 years [interquartile range (IQR): 31.7–46.2]. During a median follow‐up of 33.1 months (IQR: 17.5–52.4), 909 (35.6%) participants were LTFU, 43 (1.7%) died and 194 (7.6%) had transferred to another clinic. The probability of being LTFU was higher among PLHIV with failed pillbox return than among those who returned their pillbox [30.0%, 95% confidence interval (CI): 26.8–33.2% vs. 19.4%, 95% CI: 17.4–21.6%, respectively, at 24 months (hazard ratio = 1.67, 95% CI: 1.46–1.90; p < 0.001)]. Conclusions Failed pillbox return was associated with a higher risk of being LTFU and could be used as a simple tool to identify PLHIV for appropriate interventions to reduce their chance of being LTFU.

Abstract
INTRODUCTION Globally, HIV-related adolescent deaths have increased about 50%, especially for those who are vertically infected. This could be driven by archived drug resistance mutations (DRMs) as children grow up, which might jeopardize antiretroviral therapy (ART). Our objective was to compare HIV-1 genotypic variation between plasma RNA and proviral DNA of vertically infected adolescents (aged 10-19 years) failing ART. METHODS A comparative study was conducted in 2019 among 296 adolescents with perinatal HIV infection (ALPHI) failing ART in health facilities of the Centre Region of Cameroon. The WHO clinical stage, CD4 count and plasma viral load (PVL) were measured. For those failing ART (PVL ≥ 1000 copies/mL), RNA (plasma) and proviral DNA (buffy coat) were sequenced in the pol gene at Chantal BIYA International Reference Centre (CIRCB), Yaoundé, Cameroon. HIV-1 subtypes and DRMs were interpreted using Stanford HIVdb v.8.8 and MEGA-X. RESULTS Of the 30% (89/296) failing ART, 81 had both RNA and DNA sequences generated and three were excluded for APOBEC mutations: the mean age was 16 ± 3 years; female-to-male ratio was 3:5; median PVL was 46 856 copies/mL [interquartile range (IQR): 19 898-271 410]; median CD4 count was 264 cells/μL (IQR: 131-574); and 42% were at WHO clinical stage 3/4. Subtype concordance between RNA and DNA viral strains was 100%, with CRF02_AG being predominant (65%) and two potential new recombinants found (A1/G/K; F1/G). Adolescents with DRMs were significantly higher in plasma than in proviral DNA (92% vs. 86%, p < 0.0001). Prevalent DRMs by drug class (RNA vs. DNA respectively) were at position M184 (74% vs. 67%) for nucleoside reverse transcriptase inhibitors (NRTIs), K103 (63% vs. 59%) for non-NRTIs, and V82, L76 and M46 (2% vs. 2%) for protease inhibitors. A total of 35% (27/78) of adolescents had concordant DRM profiles in RNA and DNA, while 27% (21/78) had DRMs only in proviral DNA. The presence of archived DRMs was associated with advanced clinical stage 3/4 (OR = 0.14, p = 0.0003) and PVL < 5 Log (Copies/mL) (OR: 4.88, p = 0.006). CONCLUSIONS Although plasma RNA remains more sensitive for detecting HIV-1 DRMs, about a quarter of ALPHI experiencing ART failure in an African setting might have archived DRMs in viral reservoirs, indicating clinically occult resistance. Thus, to ensure effective ART success, proviral DNA profiling (alongside RNA genotyping) would provide additional DRMs for adolescents with advanced clinical stages and/or moderate PVL.
