Objectives: People living with HIV face several challenges as they age, including the potential for polypharmacy and increased susceptibility to drug-related adverse effects. Thus, effective and well-tolerated regimens with minimal or no drug interactions would be useful in this population. We present real-world effectiveness and safety data for individuals aged >50 years who achieved virological suppression (HIV-1 RNA <50 copies/mL) and switched to dolutegravir/lamivudine (DTG/3TC).
Methods: This retrospective, observational, single-centre study conducted in Portugal included individuals aged >50 years who switched to DTG/3TC while virologically suppressed and had ≥12 months of follow-up. Proportions of individuals maintaining virological suppression were described at 12 months; CD4+ cell counts were described at baseline and 12 months. Descriptive subgroup analyses were performed based on age, sex assigned at birth, and availability of historical genotypic resistance results.
Results: Overall, 538 individuals aged >50 years were included (74% male; mean age, 62 years; mean time on previous therapy, 160 months). High proportions (intention-to-treat population, 97%; on-treatment population, 98%) of individuals who switched to DTG/3TC maintained virological suppression through 12 months of follow-up. CD4+ cell counts remained stable (mean baseline: 727 cells/mm3 [range 94-2371]; mean month 12: 742 cells/mm3 [range 99-2659]). No individuals experienced virological failure. Nine (2%) individuals discontinued DTG/3TC for non-treatment-related reasons. Proportions with virological suppression at month 12 were similar between on-treatment subgroups by age, sex assigned at birth, and historical genotypic resistance results availability.
Conclusions: DTG/3TC demonstrated robust effectiveness and a good safety profile in individuals aged >50 years with virological suppression in Portugal.
Objective: Adherence to antiretroviral treatment (ART) plays a key role in achieving viral suppression in people living with HIV. We aimed to quantify ART adherence in the entire French HIV-infected population treated in 2019 and to determine factors of influence.
Methods: People living with HIV were identified using HIV diagnosis according to International Statistical Classification of Diseases and Related Health Problems, Tenth Revision criteria, HIV-specific laboratory tests, and prescription of antiretrovirals in 2019. Adherence was measured using the medication possession ratio (MPR; actual divided by theoretical number of tablets). Variables of interest included sex, age, type of ART, relevant comorbidities, and receiving supplementary universal health coverage for low-income citizens (CMUc).
Results: Of the n = 211 124 people living with HIV identified between 2006 and 2019, we included n = 140 607 on ART with two or more prescription fills in 2019 in this analysis. In total, 87.5% of people living with HIV were receiving ART in 2019. Mean ± standard deviation MPR was 82.5 ± 22.7%; 57% of people living with HIV had an MPR ≥90%, and 12.7% had an MPR <50%. Those with an MPR ≥90% significantly differed between males and females (59.1% and 52.8%, respectively; p < 0.001), and between CMUc recipients and non recipients (54.1% and 57.6%, respectively; p < 0.001). MPR ≥90% rate was lower for those with chronic nephropathy (50.2%), renal failure (46.6%), and tuberculosis (50.1%), and for those using psychoactive substances (52.3%). Factors associated with MPR ≥90% in multivariable analysis were older age, male sex, not receiving CMUc, more recent HIV diagnosis, and triple (vs. dual) ART.
Conclusion: In 2019, the average MPR in people living with HIV was 82.5% according to the comprehensive French health care database. Besides sociodemographic variables such as older age, male sex, and not being a CMUc recipient (i.e. of low socioeconomic status), more recent HIV diagnosis and triple therapy were independently associated with better adherence, possibly reflecting advances in ART tolerability and dosing.
Objectives: We examined adverse event (AE) reports relating to cabotegravir/rilpivirine (CAB/RPV) in the US FDA Adverse Event Reporting System (FAERS), focusing on therapeutic failure (TF) and non-therapeutic failure (NTF) outcomes.
Methods: FAERS is a database of AE and medication error reports from post-marketing surveillance. The study was granted exempt approval by the Binghamton University Institutional Review Board. We queried reports for CAB/RPV in the FAERS system from 1 January 2021 to 31 March 2024. TFs were defined as involving any of the following terms: viral load increased, virological failure, pathogen resistance, blood HIV RNA increased, treatment failure, drug ineffective, viral mutation identified, viraemia, and therapy non-responder. The top 20 most common AEs were also identified. Means, standard deviations, and percentages were used to characterize the sample.
Results: The study cohort consisted of 2605 reports. The reported sex of the study cohort was 50% male (n = 1295), 19% female (n = 505), and 31% unspecified (n = 805), with a mean ± standard deviation (SD) age of 46.9 ± 12.4 years (n = 378). The top three most reported AEs were TFs, product dose omissions, and injection site pain, with 377 (14.5%), 354 (13.6%), and 331 (12.7%) cases, respectively. The mean ± SD weight of people with a report of TF versus NTF was 101.8 ± 33.4 kg and 87.7 ± 26.7 kg, respectively (p = 0.0175).
Conclusion: Our findings suggest that healthcare professionals should have a heightened awareness of potential challenges with CAB/RPV administration, including TFs and dose omissions in real-world settings.
Objective: Our objective was to evaluate the trajectory of immunology in patients with HIV with different baseline CD4 T-cell count strata after antiretroviral therapy (ART) under long-term viral suppression.
Methods: This was a sub-analysis focused on patients with virological suppression for at least 5 years after ART. Data were obtained from the Yunnan HIV cohort in China. Patients were categorized according to prespecified baseline CD4 T-cell counts. The trajectories of CD4 T-cell count, CD8 T-cell count, and CD4/CD8 ratio changing over time were fitted using a B-spline regression model. The Cox proportional hazards regression model was used to assess the association of baseline CD4 T-cell count with the risk of both immunological responder (IR) and CD4/CD8 ratio normalization.
Results: A total of 2618 patients with a median follow-up of 7.25 years (interquartile range [IQR] 5.92-8.75) were included. Over a period of 12 years, the mean CD4 T-cell count remained above 500 cells/μL in all groups. The mean CD4/CD8 ratio was solely normalized in patients whose baseline CD4 T-cell counts were above 350 cells/μL. Patients with higher baseline CD4 T-cell counts showed higher risks of both IR and CD4/CD8 ratio normalization than those with the lowest (all p trend <0.001). A higher baseline CD4 T-cell count predicted a shorter time for both IR and CD4/CD8 ratio normalization.
Conclusions: Long-term, sustained viral suppression may not be able to fully normalize immunological functions in patients with HIV. A high baseline CD4 T-cell count benefits IR and CD4/CD8 ratio normalization.
Objectives: Our objective was to describe the prevalence of cardiovascular disease (CVD) risk factors in people of African ancestry with HIV in the UK.
Methods: We conducted a cross-sectional analysis of CVD risk factors in Black people with HIV aged ≥40 years and estimated the 10-year CVD risk using QRISK®3-2018. Correlations between body mass index (BMI) and CVD risk factors were described using Pearson correlation coefficients, and factors associated with 10-year CVD risk ≥5% were described using logistic regression.
Results: We included 833 Black people with HIV and a median age of 54 years; 54% were female, 50% were living with obesity (BMI ≥30 kg/m2), 61% had hypertension, and 19% had diabetes mellitus. CVD risk >5% ranged from 2% in female participants aged 40-49 years to 99% in men aged ≥60 years, and use of statins ranged from 7% in those with CVD risk <2.5% to 64% in those with CVD risk ≥20%. BMI was correlated (R2 0.1-0.2) with triglycerides and diastolic blood pressure in women and with glycated haemoglobin, systolic and diastolic blood pressure, and total:high-density lipoprotein (HDL) cholesterol ratio in men. In both female and male participants, older age, blood pressure, diabetes mellitus, and kidney disease were strongly associated with CVD risk ≥5%, whereas obesity, total:HDL cholesterol, triglycerides, and smoking status were variably associated with CVD risk ≥5%.
Conclusions: We report a high burden of CVD risk factors, including obesity, hypertension, and diabetes mellitus, in people of African ancestry with HIV in the UK. BMI-focused interventions in these populations may improve CVD risk while also addressing other important health issues.
Introduction: Prevention of cardiovascular disease is a major issue in the current management of people living with HIV. Concern is growing about the metabolic impact of integrase strand transfer inhibitors (INSTIs), which could lead to an increased risk of diabetes, but the data are conflicting. This is an updated version of our previous analysis, with longer follow-up and new molecules.
Methods: We retrospectively evaluated the incidence of new-onset diabetes in people living with HIV starting combined antiretroviral therapy with an INSTI compared with non-nucleoside reverse transcriptase inhibitors and protease inhibitors. Data were collected from the Dat'AIDS cohort study, a collaboration of 30 HIV treatment centres in France. We used a propensity score-based inverse probability of treatment weighting approach to adjust for baseline characteristics between the two groups (INSTI and non-INSTI).
Results: Between 2009 and 2021, a total of 12 150 people living with HIV were included. The incidence of diabetes was higher in the INSTI group than in the non-INSTI group (hazard ratio 1.38; 95% confidence interval 1.07-1.77; p = 0.012). Regardless of the third drug, but to a greater extent for INSTIs, we observed a peak of new-onset diabetes in the year following initiation of combined antiretroviral therapy.
Conclusions: The incidence of diabetes was higher in people treated with integrase inhibitors than in those receiving other third agents. This increased risk occurred both during the first year of treatment and in the longer term.
Objectives: Our objective was to assess the numbers of eligible people living with HIV attending one HIV clinic and receiving statins, the factors increasing the likelihood of statin prescription, the knowledge and involvement of primary care in cardiovascular risk prevention in people living with HIV, and the barriers to and drivers of shared care between general practitioners (GPs) and an HIV centre.
Methods: This was a retrospective case note review identifying cardiovascular risk, medications, and communication between the HIV clinic and GPs via an electronic survey of GPs identifying their knowledge about statin indications in people living with HIV.
Results: In total, 62% of GPs were unaware of the indication for statins in people living with HIV aged >40 years. A total of 33% of patients received statins, rising to 61% of patients with independent indications for statins. 92% of all statin prescriptions were provided by the GP. Statins were recommended in 25% of clinic letters but were not prescribed in 72% of these cases. There was discordance between antiretrovirals prescribed by the HIV clinic and those documented on the GP record in 60% of cases and in 40% of non-antiretroviral medications.
Conclusions: Our results indicate that GPs can engage people living with HIV in cardiovascular risk reduction measures but may not consider HIV a cardiovascular risk. Written communication alone is insufficient to improve safe patient care. Shared HIV care needs bidirectional shared medical records. Ongoing work needs to ensure that HIV is recognized as an independent cardiovascular risk factor.
