Longitudinal trends and determinants of patient-reported side effects on ART-a Swedish national registry study

Asymptomatic Cerebrospinal Fluid HIV-1 Escape: Incidence and Consequences

BACKGROUND

The incidence and clinical relevance of asymptomatic cerebrospinal fluid escape (CSFE) during antiretroviral therapy (ART) is uncertain. We examined the impact and incidence of asymptomatic CSFE in a Swedish HIV cohort.

METHODS

Neuroasymptomatic people with HIV (PWH) who have been on ART for at least 6 months with suppressed plasma viral load were followed longitudinally. CSFE was defined as either increased CSF HIV-1 RNA with concurrent plasma suppression or CSF HIV-1 RNA exceeding that in plasma when both were quantifiable. Paired CSF and plasma were analyzed for HIV-1 RNA, neopterin, neurofilament light protein (NfL), white blood cell (WBC) count, and albumin ratio.

RESULTS

Asymptomatic CSFE (cutoff 50 copies/mL) was found in 4 of 173 PWH (2%) and 5 of 449 samples (1%). The corresponding proportions were 8% of PWH and 4% for samples using a 20 copies/mL cutoff for CSF HIV-1 RNA. CSFE samples (cutoff 20 copies/mL) had a 25% higher geometric mean of CSF neopterin (P = .01) and 8% higher albumin ratio (P = .04) compared to samples without CSFE. No differences were observed in CSF NfL levels (P = .8). The odds ratio for increased CSF WBC (≥ 3 cells/μL) in samples with CSFE was 3.9 (P = .004), compared to samples without elevated CSF viral load.

CONCLUSIONS

Asymptomatic CSFE was identified in only 4 (2%) PWH, with no cases of continuous CSFE observed. Increased CSF HIV-1 RNA was associated with biomarkers of CNS immune activation and blood-brain barrier impairment, but not with biomarkers of neuronal injury.

Sexual dysfunction in women living with HIV: an updated narrative review

INTRODUCTION

Female sexual dysfunction is a significant concern for many women worldwide, with chronic health conditions such as HIV infection contributing to its prevalence. However, there is a paucity of studies focusing this subject in the available literature.

OBJECTIVES

This narrative review aimed to provide a comprehensive and updated overview of the current state of knowledge regarding sexual dysfunction in women living with HIV (WLWH).

METHODS

References for this review were identified from MEDLINE, Embase, and Cochrane databases using the search terms "sexual dysfunction" AND "HIV" AND "female" OR "woman." The final reference list was generated based on the timeline, originality, and relevance to the scope of this narrative review.

RESULTS

In the general population, female sexual function is influenced by various factors, including biological, psychological, physiological, sociocultural, and relational ones. In WLWH, the role of antiretroviral therapy in female sexual dysfunction is controversial. Although current international guidelines recommend collecting a thorough sexual life anamnesis during routine outpatient visits, sexual difficulties are often inadequately addressed.

CONCLUSION

A tailored clinical approach that focuses on the multidimensional domains of sexual dysfunction may improve the sexual health and quality of life in WLWH.

Patient-reported outcome measures in adult HIV care: A rapid scoping review of targeted outcomes and instruments used

OBJECTIVE

There is international interest in the integration of patient-reported outcome measures (PROMs) into routine HIV care, but little work has synthesized the content of published initiatives. We conducted a rapid scoping review primarily to identify their selected patient-reported outcomes and respective instruments.

METHODS

Four databases were searched on 4 May 2022 (Medline, Embase, CINAHL and PsychINFO) for relevant English language documents published from 2005 onwards. Dual review of at least 20% of records, full texts and data extraction was performed. Outcomes and instruments were classified with an adapted 14-domain taxonomy. Instruments with evidence of validation were described.

RESULTS

Of 13 062 records generated for review, we retained a final sample of 94 documents, referring to 60 distinct initiatives led mostly in the USA (n = 29; 48% of initiatives), Europe (n = 16; 27%) and Africa (n = 9; 15%). The measured patient-reported outcome domains were: mental health (n = 42; 70%), substance use (n = 23; 38%), self-management (n = 16; 27%), symptoms (n = 12; 20%), sexual/reproductive health (n = 12; 20%), physical health (n = 9; 15%), treatment (n= 8; 13%), cognition (n = 7; 12%), quality of life (n = 7; 12%), violence/abuse (n = 6; 10%), stigma (n = 6; 10%), socioeconomic issues (n = 5; 8%), social support (n = 3; 5%) and body/facial appearance (n = 1; 2%). Initiatives measured 2.6 outcome domains, on average (range = 1-11). In total, 62 distinct validated PROMs were identified, with 53 initiatives (88%) employing at least one (M = 2.2). Overwhelmingly, the most used instrument was any version of the Patient Health Questionnaire to measure symptoms of depression, employed by over a third (26; 43%) of initiatives.

CONCLUSION

Published PROM initiatives in HIV care have spanned 19 countries and disproportionately target mental health and substance use.

Factors associated with sex differences in viral non-suppression in the Swedish InfCareHIV cohort: An observational real-world study

OBJECTIVES

Women living with HIV are underrepresented in clinical trials assessing outcomes of antiretroviral treatment (ART), justifying the need for observational studies. We investigated differences in viral non-suppression between women and men in the Swedish InfCareHIV cohort and analysed results in relation to biological and socio-demographic variables and patient-reported outcome measures (PROMs).

METHODS

The study included people living with HIV (PLWH) aged ≥18 years, who initiated ART at least 6 months prior to inclusion. Data from the InfCareHIV registry 2011-2018 were collected. Associations between variables and HIV RNA ≥50 copies/mL were investigated in uni- and multivariable analyses using generalized estimating equations, providing relative risks (RRs) as effect size.

RESULTS

The study included 38% (n = 2981) women. Women were more likely to have HIV RNA ≥50 copies/mL than were men [RR = 1.20, 95% confidence interval (CI): 1.10-1.31]. After adjusting for origin and route of transmission, sex at birth was no longer associated with viral non-suppression. PROMs were available in 52.4% of PLWH, and items associated with viral non-suppression were impaired adherence in women (RR = 2.38, 95% CI: 1.79-3.17) and men (RR 1.84, 95% CI: 1.40-2.42), and experience of side effects in women (RR = 1.49, 95% CI: 1.10-2.02).

CONCLUSIONS

This observational study found a 20% higher relative risk of viral non-suppression in women than in men and the difference was associated with socio-demographic factors. The associations between PROMs and viral non-suppression varied between women and men. PROMs are important health outcomes that may identify PLWH in need of support to achieve viral non-suppression.

Difficult-to-treat HIV in Sweden: a cross-sectional study

BACKGROUND

Our aim was to examine the prevalence and characteristics of difficult-to-treat HIV in the current Swedish HIV cohort and to compare treatment outcomes between people with difficult and non-difficult-to-treat HIV.

METHODS

In this cross-sectional analysis of the Swedish HIV cohort, we identified all people with HIV currently in active care in 2023 from the national register InfCareHIV. We defined five categories of difficult-to-treat HIV: 1) advanced resistance, 2) four-drug regimen, 3) salvage therapy, 4) virologic failure within the past 12 months, and 5) ≥ 2 regimen switches following virologic failure since 2008. People classified as having difficult-to-treat HIV were compared with non-difficult for background characteristics as well as treatment outcomes (viral suppression and self-reported physical and psychological health).

RESULTS

Nine percent of the Swedish HIV cohort in 2023 (n = 8531) met at least one criterion for difficult-to-treat HIV. Most of them had ≥ 2 regimen switches (6%), and the other categories of difficult-to-treat HIV were rare (1-2% of the entire cohort). Compared with non-difficult, people with difficult-to-treat HIV were older, had an earlier first year of positive HIV test and lower CD4 counts, and were more often female. The viral suppression rate among people with difficult-to-treat HIV was 84% compared with 95% for non-difficult (p = 0.001). People with difficult-to-treat HIV reported worse physical (but not psychological) health, and this remained statistically significant after adjustment for age, sex, and transmission group.

CONCLUSIONS

Although 9% of the HIV cohort in Sweden in 2023 were classified as having difficult-to-treat HIV, a large proportion of these were virally suppressed, and challenges such as advanced resistance and need for salvage therapy are rare in the current Swedish cohort.

Sagittal Abdominal Diameter as the Best Predictor of Metabolic Syndrome in HIV-Infected Men on Antiretroviral Therapy

BACKGROUND

The interaction of human immunodeficiency virus (HIV), host and antiretroviral therapy (ART) causes a range of metabolic disorders that can be characterized as a metabolic syndrome (MetS) that increases the cardiovascular risk. MetS involves central obesity, which can be detected using different anthropometric parameters.

OBJECTIVE

To assess the abilities of different anthropometric parameters in the prediction of MetS in HIV-infected men on ART.

METHOD

The study involved 92 male participants (mean age 44.46±10.38 years), divided into two groups: with and without MetS. All subjects underwent biochemical evaluation (triglycerides, HDL-cholesterol, fasting glucose), blood pressure measurement and anthropometric assessment: body mass, body height, body mass index (BMI), body fat mass, body circumferences (chest, upper arm, forearm, waist, hip, proximal and middle thigh and calf), sagittal abdominal diameter (SAD), skinfold thicknesses (subscapular, anterior and posterior upper arm, anterior and lateral forearm, abdominal, supraspinal, thigh and calf), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), waist-to-thigh ratio (WTR), sagittal abdominal diameter-to-body height ratio (SADH), body adiposity index (BAI) and conicity index. MetS was specified according to IDF criteria.

RESULTS

Subjects with MetS had statistically significant higher values of all anthropometric parameters except middle thigh circumference, calf skinfold and body height. According to ROC analysis and Binary Logistic Regression, SAD has been shown as the best predictor of MetS with a predictive value of 21.40 cm (AUC:0.91), followed by WHR with a predictive value of 0.93.

CONCLUSION

Sagittal abdominal diameter is the strongest anthropometric indicator of MetS in HIV-infected patients on ART.

Response rates in clinical quality registries and databases that collect patient reported outcome measures: a scoping review

BACKGROUND

Patient Reported Outcome Measures (PROMs) are being increasingly introduced in clinical registries, providing a personal perspective on the expectations and impact of treatment. The aim of this study was to describe response rates (RR) to PROMs in clinical registries and databases and to examine the trends over time, and how they change with the registry type, region and disease or condition captured.

METHODS

We conducted a scoping literature review of MEDLINE and EMBASE databases, in addition to Google Scholar and grey literature. All English studies on clinical registries capturing PROMs at one or more time points were included. Follow up time points were defined as follows: baseline (if available), < 1 year, 1 to < 2 years, 2 to < 5 years, 5 to < 10 years and 10 + years. Registries were grouped according to regions of the world and health conditions. Subgroup analyses were conducted to identify trends in RRs over time. These included calculating average RRs, standard deviation and change in RRs according to total follow up time.

RESULTS

The search strategy yielded 1,767 publications. Combined with 20 reports and four websites, a total of 141 sources were used in the data extraction and analysis process. Following the data extraction, 121 registries capturing PROMs were identified. The overall average RR at baseline started at 71% and decreased to 56% at 10 + year at follow up. The highest average baseline RR of 99% was observed in Asian registries and in registries capturing data on chronic conditions (85%). Overall, the average RR declined as follow up time increased.

CONCLUSION

A large variation and downward trend in PROMs RRs was observed in most of the registries identified in our review. Formal recommendations are required for consistent collection, follow up and reporting of PROMs data in a registry setting to improve patient care and clinical practice. Further research studies are needed to determine acceptable RRs for PROMs captured in clinical registries.

Cohort profile: InfCareHIV, a prospective registry-based cohort study of people with diagnosed HIV in Sweden

PURPOSE

The Swedish InfCareHIV cohort was established in 2003 to ensure equal and effective care of people living with HIV (PLHIV) and enable long-term follow-up. InfCareHIV functions equally as a decision support system as a quality registry, ensuring up-to-date data reported in real time.

PARTICIPANTS

InfCareHIV includes data on >99% of all people with diagnosed HIV in Sweden and up to now 13 029 have been included in the cohort. InfCareHIV includes data on HIV-related biomarkers and antiretroviral therapies (ART) and also on demographics, patient-reported outcome measures and patient-reported experience measures.

FINDINGS TO DATE

Sweden was in 2015 the first country to reach the UNAIDS (United Nations Programme on HIV/AIDS)/WHO's 90-90-90 goals. Late diagnosis of HIV infection was identified as a key problem in the Swedish HIV-epidemic, and low-level HIV viraemia while on ART associated with all-cause mortality. Increased HIV RNA load in the cerebrospinal fluid (CSF) despite suppression of the plasma viral load was found in 5% of PLHIV, a phenomenon referred to as 'CSF viral escape'. Dolutegravir-based treatment in PLHIV with pre-existing nucleoside reverse transcriptase inhibitor-mutations was non-inferior to protease inhibitor-based regimens. An increase of transmitted drug resistance was observed in the InfCareHIV cohort. Lower efficacy for protease inhibitors was not due to lower adherence to treatment. Incidence of type 2 diabetes and insulin resistance was high in the ageing HIV population. Despite ART, the risk of infection-related cancer as well as lung cancer was increased in PLHIV compared with HIV-negative. PLHIV were less likely successfully treated for cervical precancer and more likely to have human papillomavirus types not included in current HPV vaccines. Self-reported sexual satisfaction in PLHIV is improving and is higher in women than men.

FUTURE PLANS

InfCareHIV provides a unique base to study and further improve long-term treatment outcomes, comorbidity management and health-related quality of life in people with HIV in Sweden.

Sex-based epidemiological and immunovirological characteristics of people living with HIV in current follow-up at a tertiary hospital: a comparative retrospective study, Catalonia, Spain, 1982 to 2020

BackgroundEpidemiological and immunovirological features of people living with HIV (PLWH) can vary by sex.AimTo investigate, particularly according to sex, characteristics of PLWH who consulted a tertiary hospital in Barcelona, Spain, in 1982-2020.MethodsPLWH, still in active follow-up in 2020 were retrospectively analysed by sex, age at diagnosis, age at data extraction (December 2020), birth place, CD4+ cell counts, and virological failure.ResultsIn total, 5,377 PLWH (comprising 828 women; 15%) were included. HIV diagnoses in women appeared to decrease from the 1990s, representing 7.4% (61/828) of new diagnoses in 2015-2020. From 1997, proportions of new HIV diagnoses from patients born in Latin America seemed to increase; moreover, for women born outside of Spain, the median age at diagnosis appeared to become younger than for those born in Spain, with significant differences observed in 2005-2009 and 2010-2014 (31 vs 39 years (p = 0.001), and 32 vs 42 years (p < 0.001) respectively), but not in 2015-2020 (35 vs 42 years; p = 0.254). Among women, proportions of late diagnoses (CD4+ cells/mm3 < 350) were higher than men (significantly in 2015-2020: 62% (32/52) vs 46% (300/656); p = 0.030). Initially, virological failure rates were higher in women than men, but they were similar in 2015-2020 (12% (6/52) vs 8% (55/659); p = 0.431). Women ≥ 50 years old represented 68% (564/828) of women actively followed up in 2020.ConclusionsWomen still have higher rates of late HIV diagnoses than men. Among currently-followed-up women, ≥ 50 year-olds, who need age-adapted care represent a high percentage. Stratifying PLWH by sex matters for HIV prevention and control interventions.

Comparison of Metabolic Effects of Three Different Treatment Combinations with Retrospective Real-life Data in People Living with HIV

INTRODUCTION

Comorbidities are increasing in people living with HIV (PLHIV), and different treatment options have advantages and disadvantages. It is important to compare information from real-life treated cases. The aim of this study was to retrospectively evaluate the data on efficacy and clinical and laboratory findings during different antiretroviral therapies.

METHODS

Retrospective file data of 47 PLHIV using Dolutegravir and Lamivudine (3TC/DTG), Tenofovir Alafenamide Emtricitabine and Elvitegravir Cobicistat (EVG/c/TAF/FTC) and Tenofovir Disoproxil Fumarate and Emtricitabine and Efavirenz (EFV/FTC/TDF) were analyzed. Data of the patients at baseline and 12 months after antiretroviral therapy (ART) were compared.

RESULTS

About 47 PLHIV were included in the study. Of the patients, 22 (46.8%) were in the 3TC/DTG group, 19 (40.4%) in the EVG/c/TAF/FTC, and 6 (12.8%) in the EFV/FTC/TDF group. After 12 months of treatment, BMI, HIV-RNA, CD4, WBC, hemoglobin, MCV, PDW, RDW, platelet count, creatinine, eGFR, HDL, AST, glucose values of the 3TC/DTG group were significantly different (p<0.05). After 12 months of treatment, BMI, HIV-RNA, CD4 count, MCV, creatinine, eGFR, HDL, LDL, TG, TC, AST, and HOMA-IR values of the EVG/c/TAF/FTC treatment group were significantly different (p<0.05). After 12 months of treatment, HIV RNA, total bilirubin, and LDL values in the EFV/FTC/TDF treatment group were statistically different (p<0.05).

CONCLUSION

All treatment groups showed a decrease in HIV-RNA and an increase in CD4 at the end of one year. While CD4 elevation is lower in EFV recipients than in integrase inhibitor (INSTI) recipients, weight gain is higher in INSTI recipients. While the lipid profile was more positively affected in the 3TC/DTG group, lipid profiles were more negatively affected in the EVG/c/TAF/FTC group, although liver and kidney functions were preserved.

Chemical exchange saturation transfer for detection of antiretroviral drugs in brain tissue

OBJECTIVE

Antiretroviral drug theranostics facilitates the monitoring of biodistribution and efficacy of therapies designed to target HIV type-1 (HIV-1) reservoirs. To this end, we have now deployed intrinsic drug chemical exchange saturation transfer (CEST) contrasts to detect antiretroviral drugs within the central nervous system (CNS).

DESIGN AND METHODS

CEST effects for lamivudine (3TC) and emtricitabine (FTC) were measured by asymmetric magnetization transfer ratio analyses. The biodistribution of 3TC in different brain sub-regions of C57BL/6 mice treated with lipopolysaccharides was determined using MRI. CEST effects of 3TC protons were quantitated by Lorentzian fitting analysis. 3TC levels in plasma and brain regions were measured using ultraperformance liquid chromatography tandem mass spectrometry to affirm the CEST test results.

RESULTS

CEST effects of the hydroxyl and amino protons in 3TC and FTC linearly correlated to drug concentrations. 3TC was successfully detected in vivo in brain sub-regions by MRI. The imaging results were validated by measurements of CNS drug concentrations.

CONCLUSION

CEST contrasts can be used to detect antiretroviral drugs using MRI. Such detection can be used to assess spatial--temporal drug biodistribution. This is most notable within the CNS where drug biodistribution may be more limited with the final goal of better understanding antiretroviral drug-associated efficacy and potential toxicity.

Health-related quality-of-life in people living with HIV after switching to dual therapy with ritonavir-boosted darunavir + dolutegravir: a DUALIS sub-study

The DUALIS study demonstrated efficacy and safety of switching to dolutegravir plus ritonavir-boosted darunavir (DRV/r) (2DR) as compared to standard-of-care-therapy with two nucleoside reverse transcriptase inhibitors + DRV/r (3DR) in pretreated people living with HIV (PLWH), 48 weeks after switching. This DUALIS sub-study investigates health-related-quality-of-life (HrQoL) in this study-population. The Hospital Anxiety and Depression Scale (HADS) and the Medical Outcome Survey-HIV (MOS-HIV) were used assessing anxiety and depression symptoms, respectively HrQoL. Data were collected at baseline, 4, 24, and 48 weeks after randomization. Outcome scores were dichotomized and used as criteria in longitudinal models identifying differential developments. Odds ratios (ORs) with 95% confidence intervals (CIs) were computed as main measures of effects. ORs<1 indicate better results for HADS, and worse for MOS-HIV scores in the 2DR compared to 3DR group. In total, 263 subjects were randomized and treated (2DR n=131, 3DR n=132; median age 48 years). Significant different progressions could only be found for HADS-Depression scores (OR=.87, 95% CI: .78, .98, p=.02). While HADS-Depression scores decreased in the 2DR group, they increased in 3DR group. This sub-study showed no disadvantages regarding HrQoL in PLWH after switching to DTG+DRV/r. Considering lifelong requirements for antiretroviral medication, close attention to HrQL is required.

People living with HIV in Sweden report high levels of sexual satisfaction in a registry-based cohort study

Sexual satisfaction can be challenging for people living with HIV (PLWH). To investigate self-reported sexual satisfaction in PLWH and its association with HIV-related biomarkers, a retrospective observational cohort study with data on sociodemographic characteristics and changes in PLWH's assessment of their sexual satisfaction over time were retrieved from the Swedish National Quality Assurance Registry (InfCareHIV) where patient-related outcomes are reported annually. PLWH who had assessed self-reported sexual satisfaction 2011-2016 were included. Sexual satisfaction was dichotomized into sexual "satisfaction and dissatisfaction" and associations were analysed. In total, 3798 patients (66% men) answered 8202 questionnaires. Overall, 67% reported sexual satisfaction, with women more satisfied than men (72% vs 64%, p < 0.0001). Sexual satisfaction did not differ between patients on antiretroviral treatment (ART) >6 months whether the viral load was suppressed or not. Overall, the probability of reporting sexual satisfaction increased by 4% annually (p < 0.001). This increase may be explained by evolving knowledge about the minimal risks of sexual HIV transmission when on ART together with Sweden's concomitant revision of legal restrictions. The use of patient-related outcomes in clinical practice is an important tool for facilitating conversations about sexuality in order to promote the health and well-being of PLWH.
