RESUMEN

Oral PrEP's effectiveness relies on adequate adherence during periods of substantial HIV risk. Since most PrEP users will miss doses, understanding predictors within participants can help to explain adherence. We used a cross-sectional, within-participant design with 67 gay, bisexual, and other men who have sex with men taking PrEP daily. Using a questionnaire, informed by the Information Motivation Behavioral Skills Model, participants were asked about an adherent and a non-adherent episode. PrEP non-adherence was associated with non-normality of the day (p < .001), being out of the home (p < .001), weekend days (p = .01), having company (p = .02), using substances (p = 0.02), not using reminders (p = .03), lower PrEP information (p = .04), lower behavioural skills (p < .001) and less positive affect (p = .002). PrEP adherence assessment could focus on situational variations, supporting the construction of alternative strategies to facilitate adherence in these situations.

RESUMEN

ABSTRACTWomen living with HIV are reaching older age and experiencing menopause and age-related comorbidities. Data suggest that women living with HIV experience earlier menopause and more menopausal symptoms and age-related comorbidities compared to women without HIV. However, there are no guidelines on the screening for and management of age-related comorbidities and events in women living with HIV. Moreover, little is known about provision of care to this population across Europe. We surveyed 121 HIV healthcare providers in 25 World Health Organization European countries to ascertain screening practices for, and management of, menopause, psychosocial and sexual well-being and age-related comorbidities in women with HIV. Most respondents screened for diabetes, cardiovascular disease (CVD) risk factors and poor mental health at least annually. Low bone mineral density (BMD) was regularly checked but less than once a year. Fewer regularly screened for sexual well-being and intimate partner violence. Menstrual pattern and menopausal symptoms in women aged 45-54 were assessed by 67% and 59% of respondents. 44% stated that they were not confident assessing menopausal status and/or symptoms. CVD, diabetes, low BMD and poor mental health were managed mainly within HIV clinics, whereas menopause care was mainly provided by gynaecology or primary care. Most respondents stated a need for HIV and menopause guidelines. In conclusion, we found that whilst metabolic risk factors and poor mental health are regularly screened for, psychosocial and sexual well-being and menopausal symptoms could be improved. This highlights the need for international recommendations and clinician training to ensure the health of this population.

RESUMEN

OBJECTIVE: We present findings from a large cohort of individuals treated during primary HIV infection (PHI) and examine the impact of time from HIV-1 acquisition to antiretroviral therapy (ART) initiation on clinical outcomes. We also examine the temporal changes in the demographics of individuals presenting with PHI to inform HIV-1 prevention strategies. METHODS: Individuals who fulfilled the criteria of PHI and started ART within 3 months of confirmed HIV-1 diagnosis were enrolled between 2009 and 2020. Baseline demographics of those diagnosed between 2009 and 2015 (before preexposure prophylaxis (PrEP) and universal ART availability) and 2015-2020 (post-PrEP and universal ART availability) were compared. We examined the factors associated with immune recovery and time to viral suppression. RESULTS: Two hundred four individuals enrolled, 144 from 2009 to 2015 and 90 from 2015 to 2020; median follow-up was 33 months. At PHI, the median age was 33 years; 4% were women, 39% were UK-born, and 84% were MSM. The proportion of UK-born individuals was 47% in 2009-2015, compared with 29% in 2015-2020. There was an association between earlier ART initiation after PHI diagnosis and increased immune recovery; each day that ART was delayed was associated with a lower likelihood of achieving a CD4 + cell count more than 900 cells/µl [hazard ratio 0.99 (95% confidence interval, 95% CI 0.98-0.99), P  = 0.02) and CD4/CD8 more than 1.0 (hazard ratio 0.98 (95% CI 0.97-0.99). CONCLUSION: Early initiation of ART at PHI diagnosis is associated with enhanced immune recovery, providing further evidence to support immediate ART in the context of PHI. Non-UK-born MSM accounts for an increasing proportion of those with primary infection; UK HIV-1 prevention strategies should better target this group.

RESUMEN

BACKGROUND: Chemsex (the use of psychoactive drugs in sexual contexts) has been associated with HIV acquisition and other STIs, so there is benefit in identifying those most likely to start chemsex to offer risk reduction interventions such as pre-exposure prophylaxis (PrEP). To date, there have been no data from a longitudinal study analysing factors most associated with starting and stopping chemsex. METHODS: The prospective cohort study, Attitudes to and Understanding Risk of Acquisition of HIV over Time (AURAH2), collected 4 monthly and annual online questionnaire data from men who have sex with men (MSM) from 2015 to 2018. We investigate the association of sociodemographic factors, sexual behaviours and drug use with starting and stopping chemsex among 622 men who completed at least one follow-up questionnaire. Poisson models with generalised estimating equations were used to produce risk ratios (RRs) accounting for multiple starting or stopping episodes from the same individual. Multivariable analysis was adjusted for age group, ethnicity, sexual identity and university education. FINDINGS: In the multivariable analysis, the under 40 age group was significantly more likely to start chemsex by the next assessment (RR 1.79, 95% CI 1.12 to 2.86). Other factors which showed significant association with starting chemsex were unemployment (RR 2.10, 95% CI 1.02 to 4.35), smoking (RR 2.49, 95% CI 1.63 to 3.79), recent condomless sex (CLS), recent STI and postexposure prophylaxis (PEP) use in the past year (RR 2.10, 95% CI 1.33 to 3.30). Age over 40 (RR 0.71, 95% CI 0.51 to 0.99), CLS, and use of PEP (RR 0.64, 95% CI 0.47 to 0.86) and PrEP (RR 0.47, 95% CI 0.29 to 0.78) were associated with lower likelihood of stopping chemsex by the next assessment. INTERPRETATION: Knowledge of these results allows us to identify men most likely to start chemsex, thus providing an opportunity for sexual health services to intervene with a package of risk mitigation measures, especially PrEP use.

RESUMEN

OBJECTIVES: Fostemsavir, a prodrug of temsavir, is indicated for heavily treatment-experienced adults with multidrug-resistant HIV-1 infection, antiretroviral (ARV) intolerance, or safety considerations. Understanding drug-drug interactions (DDIs) is important in individuals taking fostemsavir with hormonal contraceptives or menopausal or gender-affirming hormonal therapies. METHODS: Effect of temsavir (active moiety) on the pharmacokinetics of ethinyl estradiol (EE) and norethindrone (NET) was evaluated in an open-label, single-sequence, four-cycle, four-treatment study in 26 healthy female participants (study 206279, NCT02480881). Relevant ARV-contraceptive interaction studies and guideline recommendations were reviewed; that information was then applied to other contraceptive methods and hormone-based therapies to predict the impact of fostemsavir co-administration. RESULTS: Temsavir increased EE concentrations by 40% and had no effect on NET concentrations. Fostemsavir co-administration with hormone therapy is not expected to impact hormone treatment efficacy. Fostemsavir did not impact progestin; therefore, progestin-only and non-hormonal contraceptives will not be impacted by fostemsavir. Recommendations for co-administration of fostemsavir and hormonal contraceptives or menopausal or gender-affirming hormone therapies are based upon known and predicted DDIs, ensuring adequate hormonal concentrations to maintain the target effect. CONCLUSIONS: Applying the results of Study 206279 and other relevant ARV-contraceptive studies, we recommend that when co-administering fostemsavir with combined oral contraceptives (COCs) and other oestrogen-based therapies, EE dose should not exceed 30 µg or equivalent, and caution is advised in the case of individuals with risk factors for thromboembolic events. Other oestrogen-based therapies may be co-administered with fostemsavir, with monitoring of oestrogen concentrations and appropriate dose adjustments. No impact of fostemsavir on COC efficacy is expected.

RESUMEN

Natural Killer (NK) cells play a key role in controlling HIV replication, with potential downstream impact on the size of the HIV reservoir and likelihood of viral rebound after antiretroviral therapy (ART) cessation. It is therefore important to understand how primary HIV infection (PHI) disrupts NK cell function, and how these functions are restored by early ART. We examined the impact of commencing ART during PHI on phenotypic and functional NK cell markers at treatment initiation (baseline), 3 months, 1 year, and 2 years in seven well-characterised participants in comparison to HIV seronegative volunteers. We then examined how those NK cell properties differentially impacted by ART related to time to viral rebound and HIV DNA levels in 44 individuals from the SPARTAC trial who stopped ART after 48 weeks treatment, started during PHI. NK cell markers that were significantly different between the seven people with HIV (PWH) treated for 2 years and HIV uninfected individuals included NKG2C levels in CD56dim NK cells, Tim-3 expression in CD56bright NK cells, IFN-γ expressed by CD56dim NK cells after IL-12/IL-18 stimulation and the fraction of Eomes-/T-bet+ in CD56dim and CD56bright NK cells. When exploring time to viral rebound after stopping ART among the 44 SPARTAC participants, no single NK phenotypic marker correlated with control. Higher levels of IL-12/IL-18 mediated NK cell degranulation at baseline were associated with longer times to viral rebound after treatment interruption (P=0.028). Additionally, we found higher fractions of CD56dim NK cells in individuals with lower levels of HIV DNA (P=0.048). NKG2A and NKp30 levels in CD56neg NK cells were higher in patients with lower HIV DNA levels (p=0.00174, r=-0.49 and p=0.03, r= -0.327, respectively) while CD27 levels were higher in those with higher levels of HIV DNA (p=0.026). These data show NK cell functions are heterogeneously impacted by HIV infection with a mixed picture of resolution on ART, and that while NK cells may affect HIV DNA levels and time to viral rebound, no single NK cell marker defined delayed viral rebound.

RESUMEN

OBJECTIVES: We describe here characteristics and clinical outcomes of women living with HIV attending an HIV menopause service. METHODS: This was a retrospective case note review of women attending the monthly HIV menopause clinic from January 2015 to July 2018. RESULTS: In all, 55 women attended the service. The overall mean age was 49 years; 50% were black and 20% had a previous AIDS-defining condition. All were on antiretroviral therapy (ART); the median CD4 count was 678 cells/µL; 93% had a viral load < 50 copies/mL; 7% had previous hepatitis C infection; 27% had a history of smoking; 45% had risk factors or existing cardiovascular disease; 24% had a mental health condition. The median duration of symptoms before clinic attendance was 18 months. Vasomotor symptoms (84%), menstrual cycle changes (62%), psychological (56%) and urogenital symptoms (29%) were reported. Twenty-two per cent had early menopause or premature ovarian insufficiency. The mean age at attendance of women diagnosed with menopause (n = 24) was 52 years. However, their average duration of symptoms prior to review was 28 months. A total of 61% had osteopenia/osteoporosis, 73% received menopausal hormone therapy (MHT), and 73% had symptomatic improvement, although 58% of these required higher doses of MHT. Median time on MHT was 10 months. Five patients had their ART modified. No serious MHT adverse effects were observed. CONCLUSIONS: Menopausal hormone therapy uptake was high, with most women observing an improvement in symptoms. Comorbidities were common, highlighting the need for integrated care based on a woman's needs. The long delay from initial symptoms to treatment demonstrates the need for better access to specialist advice for women experiencing menopause.

RESUMEN

There is a well-documented link between infectious diseases, especially HIV, armed conflict, lack of respect for human rights and migration. War leads to disruption of services, increased vulnerability to violence and social hardships that put individuals and especially women at risk of infections such as HIV. HIV in Europe is highly associated with migration, with over 40% of new infections being diagnosed among migrants. Our aim was to provide an overview of the factors that put migrant populations, and especially migrant women, at risk for HIV infection and to illustrate this from three different perspectives: 1) recent migration from the Ukraine, and Polish experiences in provision of HIV care to Ukrainian migrants; 2) successful HIV programs targeting African migrant women in the United Kingdom (UK); 3) the impact of the prolonged crisis and women's rights violations during the internal Afghanistan conflict. We conclude that although they may be dramatically different, situations having detrimental health effects in women often share common underlying causes, and therefore may potentially be addressed by applying universal principles that emphasise the importance of self-management of health needs, empowerment of vulnerable communities and building community strengths. As crisis situations are often unpredictable, and shortage of resources common, empowerment of communities and creation of systematic policies that proactively address women's specific needs is crucial to ensuring that vulnerable populations are able to thrive in their new environment, thereby becoming contributors to, rather than being seen as burdens to society. This can only be achieved by continuous dialogue between women's communities, health care providers, policy makers and other stakeholders involved in the care of women.

RESUMEN

OBJECTIVE: HIV-remission strategies including kick-and-kill could induce viral transcription and immune-activation in the central nervous system, potentially causing neuronal injury. We investigated the impact of kick-and-kill on plasma neurofilament light (NfL), a marker of neuro-axonal injury, in RIVER trial participants commencing antiretroviral treatment (ART) during primary infection and randomly allocated to ART-alone or kick-and-kill (ART + vaccination + vorinostat (ART + V + V)). DESIGN: Sub-study measuring serial plasma NfL concentrations. METHODS: Plasma NfL (using Simoa digital immunoassay), plasma HIV-1 RNA (using single-copy assay) and total HIV-1 DNA (using quantitative polymerase chain reaction in peripheral CD4+ T-cells) were measured at randomisation (following ≥22 weeks ART), week 12 (on final intervention day in ART + V + V) and week 18 post-randomisation. HIV-specific T-cells were quantified by intracellular cytokine staining at randomisation and week 12. Differences in plasma NfL longitudinally and by study arm were analysed using mixed models and Student's t-test. Associations with plasma NfL were assessed using linear regression and rank statistics. RESULTS: At randomisation, 58 male participants had median age 32 years and CD4+ count 696 cells/µL. No significant difference in plasma NfL was seen longitudinally and by study arm, with median plasma NfL (pg/mL) in ART-only vs ART + V + V: 7.4 vs 6.4, p = 0.16 (randomisation), 8.0 vs 6.9, p = 0.22 (week 12) and 7.1 vs 6.8, p = 0.74 (week 18). Plasma NfL did not significantly correlate with plasma HIV-1 RNA and total HIV-1 DNA concentration in peripheral CD4+ T-cells at any timepoint. While higher HIV-specific T-cell responses were seen at week 12 in ART + V + V, there were no significant correlations with plasma NfL. In multivariate analysis, higher plasma NfL was associated with older age, higher CD8+ count and lower body mass index. CONCLUSIONS: Despite evidence of vaccine-induced HIV-specific T-cell responses, we observed no evidence of increased neuro-axonal injury using plasma NfL as a biomarker up to 18 weeks following kick-and-kill, compared with ART-only.

RESUMEN

Objectives: Tenofovir DF (TDF) remains one of the preferred backbone agents for naïve HIV patients starting antiretroviral treatment (ART). The impact of TDF on renal function and metabolic parameters may vary by anchor agent. We investigated the impact of TDF in combination with 3 different integrase inhibitors on tubular and glomerular function, and metabolic parameters in ART-naïve patients.Methods: Sixty patients with normal renal function were randomised (20 per arm) to TDF/emtricitabine (FTC) plus either raltegravir (RAL) (400 mg b.d.), dolutegravir (DTG) or elvitegravir/cobicistat (EVG/c) for 48 weeks.Results: 57 patients completed the study. Significant increases in RBP/creatinine ratio at week 24 were seen in all arms [RAL +4.7 µg/mmol (CI 0.43 to 8.98, p = 0.032); DTG +4.96 µg/mmol (CI 0.77 to 9.15, p = 0.021); EVG/c +6.95 µg/mmol (CI 2.53 to 11.36, p = 0.002)], although this was not sustained to week 48 in the RAL arm. Similar changes across the arms were observed for urinary α1microglobulin (RAL +6.20 mg/L, p = 0.030; DTG +6.30 mg/L, p = 0.025; EVG/c +8.15 mg/L, p = 0.003). Urinary ß2microglobulin significantly increased at week 24 with DTG and EVG/c but remained unchanged in the RAL arm. Glomerular filtration measured with CKD-EPI creatinine-cystatin C increased significantly in the RAL arm at week 24 through 48 but declined modestly in other two arms. Total and LDL cholesterol decreased in the RAL arm, but increased in the EVG/c arm, with no significant changes in the DTG arm. Weight increased significantly from baseline with DTG but not RAL or EVG/c.Conclusion: INSTIs in combination with TDF/FTC impact differently on tubular microproteinuria, eGFR, metabolic markers and weight. Use of TDF/FTC with RAL had the least tubular effects and the most favorable metabolic profile.

RESUMEN

T cell dysfunction occurs early following HIV infection, impacting the emergence of non-AIDS morbidities and limiting curative efforts. ART initiated during primary HIV infection (PHI) can reverse this dysfunction, but the extent of recovery is unknown. We studied 66 HIV-infected individuals treated from early PHI with up to three years of ART. Compared with HIV-uninfected controls, CD4 and CD8 T cells from early HIV infection were characterised by T cell activation and increased expression of the immune checkpoint receptors (ICRs) PD1, Tim-3 and TIGIT. Three years of ART lead to partial - but not complete - normalisation of ICR expression, the dynamics of which varied for individual ICRs. For HIV-specific cells, epigenetic profiling of tetramer-sorted CD8 T cells revealed that epigenetic features of exhaustion typically seen in chronic HIV infection were already present early in PHI, and that ART initiation during PHI resulted in only a partial shift of the epigenome to one with more favourable memory characteristics. These findings suggest that although ART initiation during PHI results in significant immune reconstitution, there may be only partial resolution of HIV-related phenotypic and epigenetic changes.

RESUMEN

BACKGROUND: Prospective cohort studies of incident HIV and associated factors among gay, bisexual, and other men who have sex with men (GBMSM) in the United Kingdom are lacking. We report time trends in and factors associated with HIV incidence between 2013 and 2019 among a cohort of GBMSM: the AURAH2 prospective study. METHODS AND FINDINGS: Participants were recruited through 1 of 3 sexual health clinics in London and Brighton (July 2013 to April 2016) and self-completed a baseline paper questionnaire and subsequent 4-monthly and annual online questionnaires (March 2015 to March 2018), including information on sociodemographics, lifestyle, health and well-being, HIV status, sexual/HIV-related behaviours, and preexposure prophylaxis and postexposure prophylaxis (PrEP/PEP). Incident HIV was ascertained by linkage with national HIV surveillance data from Public Health England (PHE). We investigated the associations of HIV incidence with (1) baseline factors using mixed-effects Weibull proportional hazard models, unadjusted and adjusted for age, country of birth and ethnicity, sexuality, and education level; and (2) time-updated factors, using mixed-effects Poisson regression models. In total, 1,162 men (mean age 34 years, 82% white, 94% gay, 74% university-educated) were enrolled in the study. Thirty-three HIV seroconversions occurred over 4,618.9 person-years (PY) of follow-up: an overall HIV incidence rate (IR) of 0.71 (95% confidence interval (CI) 0.51 to 1.00) per 100 PY. Incidence declined from 1.47 (95% CI 0.48 to 4.57) per 100 PY in 2013/2014 to 0.25 (95% CI 0.08 to 0.78) per 100 PY in 2018/2019; average annual decline was 0.85-fold (p < 0.001). Baseline factors associated with HIV acquisition included the following: injection drug use (6/38 men who reported injection drug-acquired HIV; unadjusted conditional hazard ratio (HR) 27.96, 95% CI 6.99 to 111.85, p < 0.001), noninjection chemsex-related drug use (13/321; HR 6.45, 95% CI 1.84 to 22.64, p < 0.001), condomless anal sex (CLS) (26/741; HR 3.75, 95% CI 1.31 to 10·74, p = 0.014); higher number of CLS partners (HRs >10 partners [7/57]; 5 to 10 partners [5/60]; and 2 to 4 partners [11/293]: 14.04, 95% CI 4.11 to 47.98; 9.60, 95% CI 2.58 to 35.76; and 4.05, 95% CI 1.29 to 12.72, respectively, p < 0.001); CLS with HIV-positive partners (14/147; HR 6.45, 95% CI 3.15 to 13.22, p < 0.001), versatile CLS role (21/362; HR 6.35, 95% CI 2.18 to 18.51, p < 0.001), group sex (64/500; HR 8.81, 95% CI 3.07 to 25.24, p < 0.001), sex for drugs/money (4/55, HR 3.27, 95% CI 1.14 to 9.38, p = 0.027) (all in previous 3 months); previous 12-month report of a bacterial sexually transmitted infection (STI) diagnoses (21/440; HR 3.95, 95% CI 1.81 to 8.63, p < 0.001), and more than 10 new sexual partners (21/471, HRs 11 to 49, 50 to 99, and >100 new partners: 3.17, 95% CI 1.39 to 7.26; 4.40, 95% CI 1.35 to 14.29; and 4.84, 95% CI 1.05 to 22.4, respectively, p < 0.001). Results were broadly consistent for time-updated analysis (n = 622 men). The study's main limitation is that men may not be representative of the broader GBMSM population in England. CONCLUSIONS: We observed a substantial decline in HIV incidence from 2013 to 2019 among GBMSM attending sexual health clinics. Injection drug use, chemsex use, and measures of high-risk sexual behaviour were strongly associated with incident HIV. Progress towards zero new infections could be achieved if combination HIV prevention including Test and Treat strategies and routine commissioning of a PrEP programme continues across the UK and reaches all at-risk populations.

RESUMEN

OBJECTIVES: Rapid antiretroviral therapy (ART) initiation is recommended in early HIV infection (EHI), even in the absence of baseline viral resistance test result. We analysed time to viral suppression according to ART regimen started in a cohort of patients diagnosed with EHI. METHODS: Clinical records of individuals consecutively diagnosed with EHI between July 2016-June 2018 were reviewed. The distribution of clinical, virological and immunological factors was compared in treatment groups using the Mann-Whitney U-test. RESULTS: 262 individuals (97% MSM) were diagnosed with EHI. 58% of patients agreed to start ART within 14 days of diagnosis. Tenofovir-based combinations were prescribed to all patients. DRV/b was the most commonly prescribed third agent (78%), when genotypic resistance testing was not available at time of ART choice. Switching to INSTI was encouraged once VRT became available and 27% switched from DRV/b to INSTI (mainly RAL) within 28 days from ART start. Those receiving INSTI were more likely to have a baseline viral load exceeding 1 million HIV-1 RNA copies/mL compared with those starting with DRV/b. Rapid start with INSTI regimens resulted in quicker viral suppression than when DRV/b was chosen in EHI, even when that was subsequently switched to INSTI. Retention in care following rapid ART start was achieved by all patients at 24 weeks. CONCLUSIONS: Starting an INSTI-based ART combination was associated with quicker viral suppression than when a protease inhibitor-based combination was chosen. No differences in the achievement of viral suppression or in retention in care were observed.

RESUMEN

BACKGROUND: Since October, 2017 (and until October, 2020), pre-exposure prophylaxis (PrEP) has only been available in England, UK, through the PrEP Impact Trial, by purchasing it from some genitourinary medicine clinics, or via online sources. Here we report changes from 2013 to 2018 in PrEP and postexposure prophylaxis (PEP) awareness and use among HIV-negative gay, bisexual, and other men who have sex with men (MSM) and assess predictors of PrEP initiation. METHODS: In the prospective cohort study Attitudes to, and Understanding of Risk of Acquisition of HIV 2 (AURAH2), MSM were recruited from three sexual health clinics in England: two in London and one in Brighton, UK. Men were eligible if they were aged 18 years or older and HIV-negative or of unknown HIV status. Participants self-completed a baseline paper questionnaire at one of the three clinics between July 30, 2013, and April 30, 2016, and were subsequently able to complete 4-monthly and annual online questionnaires, which were available between March 1, 2015, and March 31, 2018, and collected information on sociodemographics, health and wellbeing, HIV status, and sexual behaviours. PrEP and PEP use in the previous 12 months was obtained at baseline and in annual questionnaires. We assessed trends over calendar time in 3-month periods from first enrolment to the end of the study period (July-December, 2013, was counted as one period) in use of PrEP and PEP using generalised estimating equation logistic models. We used age-adjusted Poisson models to assess factors associated with PrEP initiation among participants who reported never having used PrEP at baseline. FINDINGS: 1162 men completed a baseline questionnaire, among whom the mean age was 34 years (SD 10·4), and of those with available data, 942 (82%) of 1150 were white, 1076 (94%) of 1150 were gay, and 857 (74%) of 1159 were university educated. 622 (54%) of 1162 men completed at least one follow-up online questionnaire, of whom 483 (78%) completed at least one annual questionnaire. Overall, PrEP use in the past year increased from 0% (none of 28 respondents) in July to December, 2013, to 43% (23 of 53) in January to March, 2018. The corresponding increase in PrEP use among men who reported condomless sex with two or more partners was from 0% (none of 13 respondents) to 78% (21 of 27). PEP use peaked in April to June, 2016, at 28% (41 of 147 respondents), but decreased thereafter to 8% (four of 53) in January to March, 2018. Among 460 men who had never used PrEP at baseline, predictors of initiating PrEP included age 40-44 years (incidence rate ratio [IRR] 4·25, 95% CI 1·14-15·79) and 45 years and older (3·59, 1·08-11·97) versus younger than 25 years; and after adjustment for age, recent HIV test (5·17, 1·89-14·08), condomless sex (5·01, 2·16-11·63), condomless sex with two or more partners (5·43, 2·99-9·86), group sex (1·69, 1·01-2·84), and non-injection chemsex-related drugs use (2·86, 1·67-4·91) in the past 3 months, PEP use (4·69, 2·83-7·79) in the past 12 months, and calendar year (Jan 1, 2017, to March 31, 2018 vs July 30, 2013, to Dec 31, 2015: 21·19, 9·48-47·35). Non-employment (0·35, 0·14-0·91) and unstable or no housing (vs homeowner 0·13, 0·02-0·95) were associated with reduced rates of PrEP initiation after adjustment for age. About half of PrEP was obtained via the internet, even after the PrEP Impact trial had started (11 [48%] of 23 respondents in January to March, 2018). INTERPRETATION: PrEP awareness and use increased substantially from 2013 to 2018 among a cohort of MSM in England. Improving access to PrEP by routine commissioning by National Health Service England could increase PrEP use among all eligible MSM, but should include public health strategies to target socioeconomic and demographic disparities in knowledge and use of PrEP.

RESUMEN

Studies conducted in people living with HIV (PLHIV) report high rates of sleep disturbance, without a clear explanation as to cause or effect. Therefore, we proposed use of multiple validated questionnaires that would allow a more comprehensive evaluation of sleep quality in PLHIV. We administered eight validated sleep and wellbeing questionnaires, recording different aspects of sleep in order to provide a comprehensive description of sleep quality, quantity, daytime functioning, wakefulness, and general wellbeing. Associations with demographics and clinical data were analyzed by univariable/multivariable analyses. Of 254 subjects 99% were male (98% men who have sex with men), 88% white, mean age 41 (SD ± 9.9) years, HIV duration eight years (SD ± 6.3), 94% were on antiretroviral therapy, mean CD4 cell count was 724 cells/mm3, 81% had HIV RNA<40 copies/ml, 72% were university educated, and 60% used 'chemsex' drugs. Almost half (45%) reported poor sleep quality, 22% insomnia, 21% daytime sleepiness, and 33% fatigue. As individual factors, HIV duration ≥10 years, anxiety, depression, and recreational drug use were associated with poor quality sleep, fatigue, and poorer functional outcomes (p ≤ 0.05). The prevalence of sleep disturbance was high in our cohort of PLHIV. Sleep disturbance was associated with longer duration of HIV infection, depression, anxiety, and recreational drug use.

RESUMEN

A fourth-generation HIV test is conventionally performed at baseline for individuals given HIV post-exposure prophylaxis (PEP). However, early HIV infection may be missed by fourth-generation tests especially in settings of high HIV incidence, meaning that recently infected individuals are potentially at risk of transmitting HIV. In 2013, HIV incidence in PEP recipients at the 56 Dean Street clinic was 7.6 per 100 person-years. We therefore wished to see if using a point-of-care PCR HIV test in such individuals would shorten the testing window period and pick up early infections that would be undiagnosed by conventional tests. We compared HIV detection in PEP recipients using the Cepheid GeneXpert® HIV-1 Qual viral load (Qual VL) assay with the standard HIV tests used in our clinical service. Between March 2017 and August 2018, a Qual VL assay was performed in addition to standard baseline HIV tests in consented PEP recipients. Of 494 consented PEP recipients, 476 had valid Qual VL assay results. Of these, 474 (99.6%) had a negative Qual VL result and were also negative on standard baseline HIV tests. Two (0.4%) tested positive for HIV on Qual VL. One of these patients was also HIV-positive on all baseline HIV tests. The other had discordant baseline point-of-care HIV test results. Although no additional HIV infections were diagnosed in PEP recipients using Qual VL, in one individual, it provided confirmation of new HIV infection more quickly than the standard HIV testing pathway.

RESUMEN

Initiation of antiretroviral therapy (ART) in early compared with chronic human immunodeficiency virus (HIV) infection is associated with a smaller HIV reservoir. This longitudinal analysis of 60 individuals who began ART during primary HIV infection (PHI) investigates which pre- and posttherapy factors best predict HIV DNA levels (a correlate of reservoir size) after treatment initiation during PHI. The best predictor of HIV DNA at 1 year was pre-ART HIV DNA, which was in turn significantly associated with CD8 memory T-cell differentiation (effector memory, naive, and T-bet-Eomes- subsets), CD8 T-cell activation (CD38 expression) and T-cell immunoglobulin and mucin-domain containing-3 (Tim-3) expression on memory T cells. No associations were found for any immunological variables after 1 year of ART. Levels of HIV DNA are determined around the time of ART initiation in individuals treated during PHI. CD8 T-cell activation and memory expansion are linked to HIV DNA levels, suggesting the importance of the initial host-viral interplay in eventual reservoir size.

RESUMEN

OBJECTIVE: To evaluate the psychometric properties of the HIV Disability Questionnaire (HDQ) among people living with HIV (PLHIV) in London, United Kingdom (UK). METHODS: This is a cross-sectional measurement study. We recruited and administered the self-reported HDQ, seven criterion measures, and a demographic questionnaire with adults living with HIV accessing HIV care. We determined median and interquartile ranges (IQR) for disability presence, severity and episodic scores (range 0-100). We calculated Cronbach's alpha (α) Kuder-Richardson-20 (KR-20) statistics for disability and episodic scores respectively (internal consistency reliability), smallest detectable change (SDC) for each HDQ severity item and domain (precision), and tested 36 a priori hypotheses assessing correlations between HDQ and criterion scores (construct validity). RESULTS: Of N = 243 participants, all were male, median age 40 years, 94% currently taking antiretroviral therapy, and 22% living with ≥2 concurrent health conditions. Median HDQ domain scores ranged from 0 (IQR: 0,7) (difficulties with day-to-day activities domain) to 27 (IQR: 14, 41) (uncertainty domain). Cronbach's alpha for the HDQ severity scale ranged from 0.85 (95% Confidence Interval (CI): 0.80-0.90) in the cognitive domain to 0.93 (95%CI: 0.91-0.94) in the mental-emotional domain. The KR-20 statistic for the HDQ episodic scale ranged from 0.74 (95%CI: 0.66-0.83) in the cognitive domain to 0.91 (95%CI: 0.89-0.94) in the uncertainty domain. SDC ranged from 7.3-15.0 points on the HDQ severity scale for difficulties with day-to-day activities and cognitive symptoms domains, respectively. The majority of the construct validity hypotheses (n = 30/36, 83%) were confirmed. CONCLUSIONS: The HDQ possesses internal consistency reliability and construct validity with varied precision when administered to males living with HIV in London, UK. Clinicians and researchers may use the HDQ to measure the nature and extent of disability experienced by PLHIV in the UK, and to inform HIV service provision to address the health-related challenges among PLHIV.

RESUMEN

Background and objectives: Access to safe and reliable contraception in the context of ARVs is essential. This study aimed to investigate the steady-state pharmacokinetics (PK) of ethinylestradiol/levonorgestrel (EE/LNG) 30/150 µg (Microgynon®) and atazanavir/cobicistat (ATV/COBI) 300/150 mg (Evotaz®), co-administered in HIV negative female volunteers, and assess its safety and tolerability.Methods: This phase 1, open label, 57-day, cross over, PK study randomized participants to one of two groups: (i) group 1 received EE/LNG alone on days 1-21, EE/LNG (21 days) + ATV/COBI (14 days) in the co-administration phase (days 22-42) and ATV/COBI alone on days 43-56; (ii) group 2 followed the same sequence but started with ATV/COBI and concluding with EE/LNG. Each group underwent intensive PK sampling on days 14, 35, and 56. EE/LNG and ATV/COBI concentrations were measured using validated LC-MS/MS methods.Results: Of 14 healthy female volunteers screened, 11 attended baseline and six completed all PK phases (five withdrew secondary to side effects). Paired data were available for analysis in six subjects for EE/LNG and eight for ATV/COBI. Geometric mean ratios (GMR, with versus without ATV/COBI) and 90% confidence intervals (CI) for LNG Cmax, AUC0-24, C24 were 0.83 (0.68-1.02), 0.92 (0.71-1.18), 1.01 (0.73-1.38). GMR and 90% CI for EE Cmax, AUC0-24, C24 were 1.05 (0.92-1.19), 1.01 (0.83-1.22), 0.75 (0.60-0.93). No grade 3 or 4 adverse events or laboratory abnormalities were observed in the women who completed the study.Conclusions: Our findings showed no significant changes in LNG concentrations and a 25% decrease in EE C24 when EE/LNG was co-administered with ATV/COBI.
