RESUMEN
INTRODUCTION: The extent to which individuals living with HIV experience residential and healthcare mobility during pregnancy in the UK is unknown. We aimed to determine a minimum estimate of residential and healthcare mobility during pregnancy in people living with HIV in the UK in 2009-2019 to explore patterns of and factors associated with mobility and to assess whether mobility was associated with specific HIV outcomes. METHODS: We analyzed data from the Integrated Screening Outcomes Surveillance Service to assess pregnancies with HIV in the UK and included livebirths and stillbirths with estimated delivery in 2009-2019. Residential mobility was defined as changing residential postcode between notification and delivery, and healthcare mobility was defined as changing NHS Trust or Strategic Health Authority (SHA) in that same timeframe. We used logistic regression to determine factors associated with residential and healthcare mobility and with detectable delivery viral load. RESULTS: Among 10 305 pregnancies, 19.6% experienced residential mobility, 8.1% changed NHS Trust, and 4.5% changed SHA during pregnancy. Mobility was more likely to be experienced by younger women, migrants, and those with new antenatal diagnosis; residential but not healthcare mobility declined over time. In a fully adjusted model, mobility was not associated with having a detectable viral load at delivery. Higher proportions of infants were lost to follow-up after mobile pregnancies than after non-mobile pregnancies. CONCLUSIONS: This analysis provides new knowledge on mobility during pregnancy in the context of HIV, but further research is needed to understand its broader impacts and its utility as a marker to help identify families requiring additional follow-up and support.

INTRODUCTION: The British HIV Association (BHIVA) guidelines were amended during the coronavirus (COVID-19) pandemic, allowing for less frequent monitoring of routine bloods. We assessed the impact of this on patient outcomes. METHODS: Between April 2020 and March 2021, routine blood appointments at our HIV clinic were replaced by virtual consultations in 'stable' people living with HIV (PLWH), defined using standard operating procedure (SOP) criteria. All had an undetectable HIV viral load (VL) (<50 copies/mL). Demographic, HIV clinical information, and antiretroviral treatment (ART) data were collated using the electronic patient record (EPR). Blood results from before (baseline) and after (follow-up) the omitted appointment were analysed for each parameter. RESULTS: In all, 791/2395 PLWH were scheduled to have blood tests omitted; 381 were excluded for reasons including not fitting the SOP criteria or presenting to clinic early, and 410 were included in analysis. The demographics of the group were consistent with our whole HIV cohort. HIV VL became detectable in 8/410 individuals (1.95%, range 51-730 copies/mL). VL resuppressed in 6/8 after a median of 29 days. VL remained detectable in two individuals, both of whom remain in care. Routine blood monitoring revealed baseline and follow-up blood parameters that were largely within normal range. Four out of 12 parameters had statistically significant changes but were not considered clinically significant; 59/410 (14.4%) changed ART, most commonly for simplification. CONCLUSION: For the majority of stable PLWH included in our evaluation, the omission of routine blood monitoring during the pandemic did not have a negative impact on HIV suppression or blood monitoring outcomes. ART switch was uncommon.
RESUMEN
BACKGROUND: Women living with HIV (WLWH) are at increased risk of human papillomavirus (HPV)-related cancers. Throughout Europe, there is great heterogeneity among guidelines for screening programmes, access to HPV testing and HPV vaccination. The aim of this systematic review is to summarize available data on screening and prevention measures for HPV-related anogenital cancers in WLWH across the WHO European Region (WER). METHODS: The systematic review followed the PRISMA guidelines and was registered on Prospero. PubMed, Embase and Web of Science databases were searched to identify available studies, written in English and published between 2011 and 2022. A metanalysis was conducted using random-effects models to calculate pooled prevalence of HPV. Subgroup analyses were conducted according to country and HPV testing. RESULTS: Thirty-four articles involving 10 336 WLWH met the inclusion criteria. Studies were heterogenous in their methodology and presentation of results: 73.5% of studies focused on cervical cancer prevention, and only 4.4% on anal cancer; 76.5% of studies conducted HPV testing as a routine part of screening. The prevalence of high-risk HPV was 30.5-33.9% depending on the detection method used. A total of 77% of WLWH had cervical cytology results reported. Six studies reported the positive association of CD4 cell count <200 cells/µL with HPV prevalence and cervical abnormalities. Anal HPV testing was conducted in <8% of participants. HPV vaccination was completed in 5.6% of women (106/1902) with known vaccination status. There was no information about the vaccination status of the majority of women in the analysed studies (8434/10336). CONCLUSION: Data about screening of HPV-related anogenital cancer in WLWH in Europe are heterogenous and lacking, especially in relation to anal cancer. HPV DNA testing is not routinely done as part of screening for HPV-related cancer; guidelines should include indications for when to use this test. Low CD4 count is a risk factor for HPV infection and cytological abnormalities. HPV vaccination data are poor and, when available, vaccination rates are very low among WLWH in Europe. This review concludes that significant improvements are required for data and also consistency on guidelines for HPV screening, prevention and vaccination in WLWH.

BACKGROUND: Prevention of HIV transmission is fundamental to ending the HIV epidemic. Pre-exposure prophylaxis (PrEP) with oral tenofovir-emtricitabine (TDF-FTC) is an established HIV-prevention method; however, most PrEP services in Europe have been targeted at men who have sex with men (MSM). A survey in 2021 by Women Against Viruses in Europe (WAVE) showed considerable variation in PrEP access and guidance for women throughout Europe. WAVE therefore commissioned this systematic review to provide insight into PrEP provision and barriers to uptake for women in Europe. METHODS: PubMed, Embase, and Scopus were searched for studies (January 2013-May 2021) that reported on actual (e.g., efficacy and safety) or hypothetical (e.g., awareness, barriers, PrEP impact models) use of oral PrEP involving women (including cis, transgender, pregnant, migrant, and breastfeeding women). Search terms included HIV, pre-exposure prophylaxis (specifically TDF-FTC), and women. Studies performed outside of the World Health Organization European region were excluded. RESULTS: The search identified 4716 unique citations, and 45 peer-reviewed articles (44 studies) were included. The majority of these studies (34/44 [77%]) included recipients or potential recipients of PrEP, representing 4699 women (243 transgender women). However, few studies were women focused (4/34 [12%]) or took place outside of Western Europe (3/34 [9%]). Across the three clinical studies that reported women-specific outcomes (60 transgender women, 13 pregnant, and 19 cis women), no breakthrough infections were recorded during the use of PrEP. Lack of awareness of PrEP, low self-estimation of HIV acquisition risk, concerns about stigma, lack of protection against other sexually transmitted infections, and PrEP interaction with hormones (for transgender women) were identified as barriers to use. The remaining studies examined healthcare professionals' perceptions of PrEP (9/44 [20%]), asked for public opinion (2/44 [5%]), or modelled the potential of PrEP for HIV prevention (1/44 [2%]). CONCLUSIONS: This review revealed a notable lack of literature on PrEP for cis and transgender women in Europe. This is synonymous with a lack of PrEP provision for women in this region. Barriers to PrEP uptake are complex and rooted in institutional and societal stigma, which must be addressed at policy level. HIV prevention with PrEP is not 'one size fits all' and requires a nuanced gender-responsive approach. Further research into the use of PrEP in cis, pregnant, breastfeeding, and transgender women is essential if we are to stop HIV transmission by 2030.

OBJECTIVES: The aim was to review and analyse evidence on the impact of service integration on quality of care for women living with HIV. METHODS: Evidence search in September 2020 using the PICO format yielded 60 potential papers. Inclusion required evidence of measurement of an outcome associated with service delivery within a system showing clear integration of services exclusively for women living with HIV. In all, 60 papers were screened, 27 were excluded at the abstract stage, and 17 were excluded after full text review, leaving 20 final papers included in this review. RESULTS: Three papers measured the impact of integrating sexual health services and all showed some measure of improved quality of care. Outcome measures considered in this paper were impact on uptake, prevention, user satisfaction, user knowledge and cost-effectiveness. Ten papers studied the impact of integrating family planning, with eight papers suggesting positive outcomes. Eleven papers studied integrated cervical cytology services with 10 able to demonstrate positive impact. Two papers assessed integrating menopause services and two looked at integration of psychological and social services. The most described positive impact was improved user knowledge and satisfaction. There were two main methods of integration demonstrated, described as 'upskilling' of staff and 'guest services'. CONCLUSIONS: Integrating services can create opportunities to improve the quality of patient-centred care whilst promoting the sexual, reproductive and human rights of women living with HIV, with an emphasis on designing services to suit local contexts.

OBJECTIVES: Effective antiretroviral therapy (ART) has improved the life expectancy of women living with HIV (WLWH). This population is now experiencing age-related comorbidities. This systematic review presents the current understanding of the prevalence and impact of comorbidities in WLWH in the modern ART era. METHODS: MEDLINE and Embase were searched for studies (1 January 2010 to 1 September 2020) reporting the prevalence of cardiovascular, bone, renal and neurocognitive disease in WLWH aged > 18 years. Studies were included if at least 100 participants (or > 50%) were female and data analysis included prevalence by sex. RESULTS: In all, 3050 articles were identified and screened; 153 full-text articles were assessed for eligibility and 38 were included in the final review. Significant gaps in the literature were identified, notably a lack of data on WLWH aged > 50 years. The data suggest a high burden of cardiovascular, bone, renal and neurocognitive disease in WLWH compared with HIV negative women. Traditional risk factors, such as hypertension, diabetes and dyslipidaemia, were common and often poorly managed. Generalizability of the results was limited, as many studies were conducted in the USA. Comparisons between WLWH and men with HIV were limited by marked differences in demographic and socioeconomic factors. CONCLUSIONS: Women living with HIV experience a high burden of comorbid disease. Traditional risk factors are common and often poorly managed. This review also highlights the magnitude of differences between women and men living with HIV beyond the pathophysiological. Future research must unpick the complex drivers of morbidity in WLWH, to improve the holistic management of this population.

OBJECTIVES: Tenofovir disoproxil fumarate (TDF) is associated with reduced bone mineral density (BMD). The aim of the study was to evaluate changes in BMD in women who switched from TDF, emtricitabine and a nonnucleoside reverse transcriptase inhibitor (TDF/FTC/NNRTI) to abacavir, lamivudine and dolutegravir (ABC/3TC/DTG). METHODS: We conducted a randomized controlled trial in which women aged ≥ 40 years were randomized 1:2 to continue TDF/FTC/NNRTI or switch to ABC/3TC/DTG. We analysed changes in BMD at the hip and lumbar spine from baseline to week 96 using linear regression, and markers of bone turnover and kidney function using repeated measures mixed effects models with multiple imputation for missing data. We conducted exploratory analyses of weight, mental health, sleep and symptoms attributed to HIV infection and antiretroviral therapy. RESULTS: Ninety-one women [mean (standard deviation) age 50.4 (6.6) years] were randomized. Women who switched to ABC/3TC/DTG maintained viral suppression and experienced improvements in BMD at the lumbar spine (but not the neck of the femur or the total hip), bone resorption markers and proteinuria (total protein, albumin and retinol-binding protein) and modest weight gain without changes in body mass index. Although mean anxiety, depression and sleep scores did not differ between the two study arms, anxiety, depression and sleep disturbance at baseline predicted ABC/3TC/DTG discontinuation for neuropsychiatric side effects [odds ratios (95% confidence intervals) 11.9 (2.0-71.6), 16.0 (2.6-97.9) and 10.0 (1.8-56.0), respectively]. CONCLUSIONS: Switching from TDF/FTC/NNRTI to ABC/3TC/DTG improved the BMD of the lumbar spine and kidney function. These benefits need to be balanced against modest weight gain and the need for antiretroviral therapy substitutions in a proportion of participants.

OBJECTIVES: We examined follicle-stimulating hormone (FSH) levels in women living with HIV aged > 45 reporting ≥ 12 months' amenorrhoea, and investigated correlation with menopausal symptoms. METHODS: A cross-sectional substudy of 85 women from the Positive Transitions through the Menopause (PRIME) Study who reported irregular periods at entry into the PRIME Study and ≥ 12 months' amenorrhoea at recruitment into this substudy. Serum FSH was supplemented with clinical data and menopausal symptom assessment. Serum FSH > 30 mIU/mL was defined as consistent with postmenopausal status. Associations between FSH and menopausal symptom severity were assessed using Pearson's correlation and the Kruskal-Wallis test. RESULTS: Median age was 53 years [interquartile range (IQR): 51-55]; all were on antiretroviral therapy, three-quarters (n = 65) had a CD4 T-cell count > 500 cells/µL and 91.8% (n = 78) had an HIV viral load (VL) < 50 copies/mL. Median FSH was 65.9 mIU/mL (IQR: 49.1-78.6). Only four women (4.7%) had FSH ≤ 30 mIU/mL; none reported smoking or drug use, all had CD4 T-cell count ≥ 200 cells/µL, and one had viral load (VL) ≥ 50 copies/mL. Median body mass index (BMI) was elevated compared with women with FSH > 30 mIU/mL (40.8 vs. 30.5 kg/m2 ). Over a quarter (28.2%) reported severe menopausal symptoms, with no correlation between FSH and severity of menopausal symptoms (p = 0.21), or hot flushes (p = 0.37). CONCLUSIONS: Four women in this small substudy had low FSH despite being amenorrhoeic; all had BMI ≥ 35 kg/m2 . We found that 95% of women with HIV aged > 45 years reporting ≥ 12 months' amenorrhoea had elevated FSH, suggesting that menopausal status can be ascertained from menstrual history alone in this group.

BACKGROUND: Modeling of the London hepatitis C virus (HCV) epidemic in men who have sex with men (MSM) and are living with human immunodeficiency virus (HIV) suggested that early access to direct-acting antiviral (DAA) treatment may reduce incidence. With high rates of linkage to care, microelimination of HCV within MSM living with HIV may be realistic ahead of 2030 World Health Organization targets. We examined trends in HCV incidence in the pre- and post-DAA eras for MSM living with HIV in London and Brighton, United Kingdom. METHODS: A retrospective cohort study was conducted at 5 HIV clinics in London and Brighton between 2013 and 2018. Each site reported all acute HCV episodes during the study period. Treatment timing data were collected. Incidence rates and reinfection proportion were calculated. RESULTS: A total of.378 acute HCV infections were identified, comprising 292 first infections and 86 reinfections. Incidence rates of acute HCV in MSM living with HIV peaked at 14.57/1000 person-years of follow-up (PYFU; 95% confidence interval [CI], 10.95-18.20) in 2015. Rates fell to 4.63/1000 PYFU (95% CI, 2.60 to 6.67) by 2018. Time from diagnosis to starting treatment declined from 29.8 (2013) to 3.7 months (2018). CONCLUSIONS: We observed a 78% reduction in the incidence of first HCV episode and a 68% reduction in overall HCV incidence since the epidemic peak in 2015, which coincides with wider access to DAAs in England. Further interventions to reduce transmission, including earlier access to treatment and for reinfection, are likely needed for microelimination to be achieved in this population.

Using data from the PRIME Study, an observational study of the menopause in women living with HIV in England, we explored the association between menopausal symptoms and: (i) antiretroviral therapy (ART) adherence and (ii) HIV clinic attendance. We measured menopausal symptom severity with the Menopause Rating Scale (MRS, score ≥17 indicating severe symptoms), adherence with the CPCRA Antiretroviral Medication Adherence Self-Report Form, and ascertained HIV clinic attendance via self-report. Odds ratios were obtained using logistic regression. Women who reported severe menopausal symptoms had greater odds of suboptimal ART adherence (adjusted odds ratio (AOR) 2.22; 95% CI 1.13, 4.35) and suboptimal clinic attendance (AOR 1.52; 95% CI 1.01, 2.29). When psychological, somatic and urogenital domains of the MRS were analysed individually there was no association between adherence and severe symptoms (all p > 0.1), however there was an association between suboptimal HIV clinic attendance and severe somatic (AOR 1.98; 95% CI 1.24, 3.16) and psychological (AOR 1.76; 95% CI 1.17, 2.65) symptoms. Severe menopausal symptoms were significantly associated with sub-optimal ART adherence and HIV clinic attendance, however we cannot infer causality, highlighting the need for longitudinal data.

We sought to characterize risk factors and patterns of HCV transmission amongst men who have sex with men (MSM). MSM with recently acquired HCV (AHCV) were prospectively recruited ('clinic cohort') between January and September 2017. Clinical data and risk behaviours were identified and blood obtained for HCV whole genome sequencing. Phylogenetic analyses were performed, using sequences from this cohort and two other AHCV cohorts, to identify transmission clusters. Sixteen (40.0%) men in the clinic cohort were HIV-negative MSM. HIV-negative MSM were younger than HIV-positive MSM; most (81.3%) had taken HIV PrEP in the preceding year. Eighteen men (45.0%) reported injection drug use; most (34, 85.0%) reported noninjection drug use in the last year. Most in both groups reported condomless anal sex, fisting and sex in a group environment. Few (7, 17.5%) men thought partners may have had HCV. There were 52 sequences in the HCV genotype 1a phylogeny, 18 from the clinic cohort and 34 from other AHCV cohorts; 47 (90.4%) clustered with ≥1 other sequence. There were 7 clusters of 2-27 sequences; 6 clusters contained HIV-negative and HIV-positive MSM and 1 cluster only HIV-positive MSM. Four of these clusters were part of larger clusters first described in 2007. PrEP-using MSM are at risk of HCV, sharing similar risk factors to HIV-positive MSM. Phylogenetics highlights that PrEP-using and HIV-positive MSM are involved in the same HCV transmission networks. Few men demonstrated HCV awareness and risk reduction strategies should be expanded.

Increasing numbers of women living with HIV are reaching their midlife. We explore the association of HIV status with sexual function (SF) in women aged 45-60 using two national cross-sectional surveys: the third British National Survey of Sexual Attitudes and Lifestyles ("Natsal-3") and "PRIME", a survey of women living with HIV attending HIV clinics across England. Both studies asked the same questions about SF that take account not only sexual difficulties but also the relationship context and overall level of satisfaction, which collectively allowed an overall SF score to be derived. We undertook analyses of sexually-active women aged 45-60 from Natsal-3 (N = 1228, presumed HIV-negative given the low estimated prevalence of HIV in Britain) and PRIME (N = 386 women living with HIV). Women living with HIV were compared to Natsal-3 participants using multivariable logistic regression (adjusting for key confounders identified a priori: ethnicity, ongoing relationship status, depression and number of chronic conditions) and propensity scoring. Relative to Natsal-3 participants, women living with HIV were more likely to: have low overall SF (adjusted odds ratio (AOR) 3.75 [2.15-6.56]), report ≥1 sexual problem(s) lasting ≥3 months (AOR 2.44 [1.49-4.00]), and report almost all 8 sexual problems asked about (AORs all ≥2.30). The association between HIV status and low SF remained statistically significant when using propensity scoring (AOR 2.43 [1.68-3.51]). Among women living with HIV (only), low SF was more common in those who were postmenopausal vs. Premenopausal (55.6% vs. 40.4%). This study suggests a negative association between HIV status and sexual function in women aged 45-60. We recommend routine assessment of SF in women living with HIV.

BACKGROUND: In pregnancy, reduction of HIV plasma viral load (pVL) for the prevention of vertical transmission is time-constrained. The study primary objective is to investigate factors associated with faster initial HIV RNA half-life decay when combination antiretroviral treatment (cART) is initiated in pregnancy. METHODS: This was a multicentre, retrospective, observational study, conducted in south England, United Kingdom, between August 2001 and February 2018. Data were extracted from case notes of eligible women initiating cART during the index pregnancy. Anonymised data were collated and analysed centrally. Regression analyses were conducted to determine factors associated with faster HIV RNA half-life decay in the first 14 days after commencing cART (first-phase), and with achieving an undetectable maternal pVL by 36 weeks' gestation. We then assessed whether HIV- and obstetric- related parameters differed by antiretroviral third agent class and whether the proportions of women with undetectable pVL at 36 weeks' gestation and at delivery differed by antiretroviral third agent class. RESULTS: Baseline pVL was the only independent factor associated with faster first-phase HIV RNA half-life decay on commencing cART. Lower pVL on day 14 after starting cART was associated with an increased likelihood of achieving an undetectable pVL by 36 weeks' gestation. Integrase inhibitor-based cART was associated with a faster first-phase HIV RNA half-life decay on commencing cART. Overall, 73% and 85% of women had an undetectable pVL at 36 weeks' gestation and at delivery respectively, with no significant difference by antiretroviral third agent class. CONCLUSIONS: Only high baseline pVL independently contributed to a faster rate of first-phase viral half-life decay. pVL at 14 days after initiating cART allows early identification of treatment failure. In the first 14 days after initiating cART in pregnancy, integrase inhibitor-based cART reduced maternal pVL faster than protease inhibitor- and non-nucleoside reverse transcriptase-based cART. While our study findings support INSTI use when initiated in pregnancy especially when initiated at later gestations and in those with higher baseline pVL, other non-INSTI based cART with more data on safety in pregnancy also performed well.

In this prospective study conducted from October 2013 to June 2015 in Brighton, England, we examined differences between men and women in new-onset major depressive disorder (MDD) during interferon-alpha-based (IFN-α) therapy for hepatitis C virus (HCV). We included 155 HCV-infected patients (47 women), eligible to receive HCV therapy, including direct-acting antivirals. The Semi-Structured Clinical Interview was used to assess MDD. Severity of depressive symptoms was assessed using the Hamilton Depression Rating Scale. Patients were assessed at baseline, during treatment and 6 months after treatment completion. A significant increase in depressive symptoms was observed in the total sample from baseline to week 4, and a significant decrease was observed from end of treatment (week 24) to the sustained virological response (SVR) end point at 6 months posttreatment. Women were more likely to have a MDD at week 24. In both men and women, neurovegetative and mood-cognitive syndromes increased significantly at the early stage of treatment but remitted by the end of HCV therapy. Proportions with SVR were similar among females and males (91.5 percent vs. 87 percent). Under an inflammatory condition, boosted by interferon-based treatments, these results suggest that female gender is not associated with increased vulnerability for developing depression during IFN-α therapy.

Effective combination antiretroviral therapy (cART) has lead to a significant reduction in the prevalence and incidence of central nervous system (CNS) HIV-associated brain disease, particularly CNS opportunistic infections and HIV encephalitis. Despite this, cognitive deficits in people living with HIV, also known as HIV-associated neurocognitive disorders (HAND) have become more prevalent in recent years. The pathogenesis of HAND is likely to be multifactorial, however recent evidence suggests that brain microglial activation is the most likely pathogenic mechanism. Recent developments in positron emission tomography (PET) brain neuroimaging using novel brain radioligands targeting a variety of physiological changes in the brains of HIV-positive individuals have improved our understanding of the mechanisms associated with the development of HAND. This review will highlight recent PET brain neuroimaging studies in the cART era, focusing on physiological and neurochemical changes associated with HAND in people living with HIV.

Recent advances in antiviral therapy have improved outcomes in HIV-positive individuals co-infected with hepatitis B and C virus (HBV/HCV). Our aim was to assess prevalence and predictors of chronic liver disease (CLD) due to the metabolic syndrome (MS), alcohol and antiretrovirals (ARVs) use in HIV-monoinfected individuals. This was a retrospective cohort study (2005-2012). HIV-positive patients with negative HBV/HCV serology and at least two elevated alanine aminotransferase (ALT) levels six months apart were included. Data are presented as mean ± SD or percentage. Despite negative viral serology, 27% (1047/3872) of HIV-positive individuals had persistently elevated ALT. Only 243 (23.2%) were investigated (by imaging in the majority, only 58 undergoing liver biopsy/transient elastography). CLD was identified in 66.2%, this being clinically significant in one in four individuals. Potential CLD risk factors were alcohol (44.2%), hepatotoxic ARVs (74.1%) and MS risk factors (68%) with 68.7% having >1 risk factor. On multivariate logistic regression analysis serum triglyceride (OR 1.482, 95% CI 1.053-2.086, p = .024) was the only independent predictor of CLD. Overall, 4.3% were referred to Hepatology services. In conclusion, less than 6% of HIV-monoinfected individuals with persistently elevated ALT undergo objective assessment of hepatic fibrosis. Despite non-stringent criteria, some degree of non-viral CLD is identified in approximately two-thirds of those investigated, risk factors being synonymous with those for the MS. This increasing yet under-recognised non-viral CLD burden warrants timely recognition to prevent long-term morbidity and mortality.
