Redefining therapeutic success in HIV patients: an expert view

Cross-sectional analysis of a cohort of people over 65 years of age living with HIV

INTRODUCTION

This study aims to describe and analyze the characteristics of aged people who are living with HIV (APHIV) and evaluate their association on the comorbidities they currently have.

METHODS

Cross-sectional analysis of APHIV under active follow-up at the Infectious Diseases Unit of the University Clinical Hospital of Santiago de Compostela. Demographic and clinical data were analyzed, along with their association with the development of comorbidities in this population. A correlation and multiple linear regression analysis were performed for this purpose.

RESULTS

Eighty-five APHIV, 65 males and 20 females, with an average age of 69 years (IQR 8) and a duration of living with HIV of 17 years (SD 7), were studied. 41% of them had their initial diagnosis with AIDS. The most common comorbidities are hypertension and dyslipidemia in 55% and 52%, respectively. 40% of APHIV take at least 5 medications. 35% have received more than 5 lines of antiretroviral treatment. At the time of analysis, all APHIV have an undetectable viral load. No significant association was observed between the number of comorbidities and various characteristics of APHIV; however, a weak correlation was noted among age, the cumulative number of antiretroviral treatments received throughout their lives, and the number of comorbidities.

CONCLUSIONS

This analysis highlights the substantial burden of comorbidities and polypharmacy experienced by APHIV. Further studies are needed to better understand the characteristics and variables influencing their development.

Perspectives of people with HIV and HIV clinicians on characteristics of antiretroviral treatment and HIV-related symptoms

OBJECTIVES

We aimed to assess HIV symptoms from the perspective of both patients and HIV specialists and the impact of discontinuing antiretroviral treatment (ART) on symptomology. We gathered opinions from HIV specialists and people living with HIV about ideal ART parameters and treatment satisfaction.

METHODS

Ex post-facto cross-sectional surveys were administered to 502 people living with HIV and 101 HIV clinicians in Spain (18 sites).

RESULTS

The median age of participants with HIV was 43.2 years, 74.5% were male, and 91.6% had an undetectable viral load. The mean time since initiation of ART was 10.2 years. Between 54% and 67% of people living with HIV reported experiencing nervousness or anxiety, sadness, fatigue, sleep problems, or muscle/joint pain during the preceding 4 weeks. However, only 22%-27% of specialists acknowledged the presence of these symptoms. The most bothersome symptoms were related to mental health or the central nervous system. There were significant differences between the burden of symptoms reported by people living with HIV and those acknowledged by specialists. The symptoms that more frequently caused ART discontinuation were depression, dizziness, and sleep problems. Both people living with HIV and specialists prioritized ART efficacy and low toxicity, but their importance ratings differed for 5 of the 11 ART characteristics assessed. People living with HIV rated their satisfaction with ART at a mean (± standard deviation) of 8.9 ± 1.5 out of 10, whereas HIV specialists rated it lower, at 8.3 ± 0.7 (p < 0.001).

CONCLUSIONS

Despite advances in HIV care and treatment, a large proportion of patients still experience symptoms. HIV specialists may not be fully aware of these. People living with HIV and HIV specialists are, overall, satisfied with ART. However, the importance they place on different ART characteristics may vary.

Effectiveness and safety of bictegravir/emtricitabine/tenofovir alafenamide in HIV late presenters

OBJECTIVES

The efficacy of BIC/FTC/TAF in HIV late presenters initiating antiretroviral therapy (ART) has not been sufficiently evaluated.

METHODS

The aim of this study was to assess the effectiveness and tolerability of BIC/FTC/TAF compared to other first-line antiretroviral regimens in treatment-naïve adult individuals from the CoRIS Cohort starting ART with CD4 counts <200 cells/mm3 and/or AIDS-defining conditions between January 1st 2019 and November 30th 2020. Logistic regression models were used to estimate odds ratios (ORs) of association between initial regimen and achievement of viral suppression (VS) (primary objective), defined as HIV RNA <50 cop/mL, and immunological recovery (IR) (secondary objective), defined as CD4 count >200 cells/mm3, at weeks 24 and 48 after initiation of ART.

RESULTS

We evaluated 314 individuals (84.7% men, median age 40 years). Of them, 158 initiated with BIC/FTC/TAF. At inclusion, 117 had an AIDS-defining condition. In multivariable analyses, individuals with AIDS-defining conditions initiating ART with BIC/FTC/TAF achieved higher rates of VS at 24 weeks than other regimens (aOR: 0.2; 95% CI: 0.06-0.64) and, at 48 weeks, than DTG/ABC/3TC (aOR: 0.06; 95% CI: 0.01-0.76) and DTG + TDF/3TC (aOR: 0.2; 95% CI: 0.47-0.9). No other differences in VS or IR were observed. At 24 and 48 weeks after ART initiation, treatment discontinuations were lower with BIC/FTC/TAF than with other regimens (3.2% and 7.6% vs. 24.4% and 37.8%, respectively; P < 0.005).

CONCLUSION

Our results suggest that BIC/FTC/TAF could be a preferred regimen as initial therapy in HIV late presenters because of its high effectiveness and good tolerability.

Pillars of long-term antiretroviral therapy success

BACKGROUND

Meeting the challenge of antiretroviral therapy (ART) whose efficacy can last a lifetime requires continuous updating of the virological, pharmacological, and quality of life outcomes to be pursued and a continuous review of literature data on the efficacy and tolerability of new drugs and therapeutic strategies.

METHODS

With the aim of identifying open questions and answers about the current controversies in modern ART, we adapted the Design Thinking methodology to the needs of the design phase of a scientific article, involving a team of experts in HIV care.

RESULTS

Five main pillars of treatment success were discussed: sustained virologic suppression over time; immunological recovery; pharmacological attributes; long-term tolerability and safety of ART; and people's satisfaction and quality of life. The definition of the outcomes to be achieved in each thematic area and the tools to achieve them were reviewed and discussed.

CONCLUSIONS

Long-term treatment success should be intended as a combination of HIV-RNA suppression, immune recovery, and high quality of life. To achieve this, the regimen should be well-tolerated, with high potency, genetic barrier, and forgiveness, and should be tailored by a person-centered perspective, based on individual needs, preferences, and therapeutic history.

HIV-Specific Reported Outcome Measures: Systematic Review of Psychometric Properties

BACKGROUND

The management of people living with HIV and AIDS is multidimensional and complex. Using patient-reported outcome measures (PROMs) has been increasingly recognized to be the key factor for providing patient-centered health care to meet the lifelong needs of people living with HIV and AIDS from diagnosis to death. However, there is currently no consensus on a PROM recommended for health care providers and researchers to assess health outcomes in people living with HIV and AIDS.

OBJECTIVE

The purpose of this systematic review was to summarize and categorize the available validated HIV-specific PROMs in adults living with HIV and AIDS and to assess these PROMs using the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) methodology.

METHODS

This systematic review followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A literature search of 3 recommended databases (PubMed, Embase, and PsychINFO) was conducted on January 15, 2021. Studies were included if they assessed any psychometric property of HIV-specific PROMs in adults living with HIV and AIDS and met the eligibility criteria. The PROMs were assessed for 9 psychometric properties, evaluated in each included study following the COSMIN methodology by assessing the following: the methodological quality assessed using the COSMIN risk of bias checklist; overall rating of results; level of evidence assessed using the modified Grading of Recommendations, Assessment, Development, and Evaluation approach; and level of recommendation.

RESULTS

A total of 88 PROMs classified into 8 categories, assessing the psychometric properties of PROMs for adults living with HIV and AIDS, were identified in 152 studies including 79,213 people living with HIV and AIDS. The psychometric properties of most included PROMs were rated with insufficient evidence. The PROMs that received class A recommendation were the Poz Quality of Life, HIV Symptom Index or Symptoms Distress Module of the Adult AIDS Clinical Trial Group, and People Living with HIV Resilience Scale. In addition, because of a lack of evidence, recommendations regarding use could not be made for most of the remaining assessed PROMs (received class B recommendation).

CONCLUSIONS

This systematic review recommends 3 PROMs to assess health outcomes in adults living with HIV and AIDS. However, all these PROMs have some shortcomings. In addition, most of the included PROMs do not have sufficient evidence for assessing their psychometric properties and require a more comprehensive validation of the psychometric properties in the future to provide more scientific evidence. Thus, our findings may provide a reference for the selection of high-quality HIV-specific PROMs by health care providers and researchers for clinical practice and research.

Trajectories of CD4+/CD8+ T-Cells Ratio 96 Weeks after Switching to Dolutegravir-Based Two-Drug Regimens: Results from a Multicenter Prospective Cohort Study

The aim of the present study was to evaluate CD4/CD8 dynamics in patients on dolutegravir (DTG)-based two-drug regimens (2DRs) and compare them with DTG-containing triple-drug regimens (3DRs). A prospective observational study was performed in the context of the SCOLTA cohort. Experienced PWH with HIV-RNA < 50 copies/mL were included if they were on the DTG-2DR, the DTG + tenofovir/emtricitabine (TDF/FTC) regimen, the DTG + tenofovir alafenamide (TAF)/FTC regimen, or the DTG + abacavir/lamivudine (ABC/3TC) regimen; they were followed-up for at least one year. A total of 533 PWH were enrolled, 120 in the DTG + 3TC group, 38 in the DTG + protease inhibitors (PI) group, 67 in the DTG + rilpivirine (RPV) group, 49 in the DTG + TDF/FTC group, 27 in the DTG + TAF/FTC group, and 232 in the DTG + ABC/3TC group. After one year, the CD4/CD8 ratio significantly increased in the PWH treated with DTG + 3TC (+0.08 ± 0.26), DTG + TDF/FTC (+0.1 ± 0.19), and DTG + ABC/3TC (+0.08 ± 0.25). At two years, the CD4/CD8 increase was confirmed for PWH on DTG + TDF/FTC (+0.16 ± 0.28) and DTG + ABC/3TC (+0.1 ± 0.3). In the SCOLTA cohort, PWH on 2DRs experienced a CD4/CD8 increase only in the DTG + 3TC group. Controlled studies with longer follow-up will clarify the long-term immunological and clinical impacts of DTG-2DR.

Importance of multidisciplinary collaboration for smooth kidney transplantation in HIV-infected patients with chronic kidney disease: a case report

Background

Antiretroviral therapy (ART) has reduced mortality caused by AIDS resulting from HIV infection. Meanwhile, the prevalence of chronic kidney disease, a chronic HIV complication, is increasing. Antiretroviral therapy has improved the life expectancy of HIV-infected kidney transplant recipients. In Japan, discrimination and prejudice against HIV persist, and few kidney transplants are performed. We report three cases in which kidney transplantation was smoothly performed with multidisciplinary collaboration.

Case presentation

The first case involved a 29-year-old male urgently hospitalized due to severe kidney dysfunction, diagnosed with HIV-associated nephropathy (HIVAN), and placed on maintenance dialysis. The patient was administered oral lamivudine, abacavir, and raltegravir as ART and underwent blood group-matched living donor kidney transplantation at age 32. The second case involved a 49-year-old male diagnosed as HIV-positive at age 33 and placed on maintenance dialysis for HIVAN at age 47. Darunavir, ritonavir, and dolutegravir (DTG) were initially administered. However, the ART was switched to rilpivirine (RPV) and DTG prior to kidney transplantation because of potential ART interactions with calcineurin inhibitors. The patient underwent blood group-matched living donor kidney transplantation. The third case involved a 41-year-old male diagnosed as HIV-positive at 23 years old and treated with RPV and DTG. Due to autosomal dominant polycystic kidney disease (ADPKD), his kidney function gradually worsened, and he was started on hemodialysis. He underwent hemodialysis, followed by blood type-matched living donor kidney transplantation. In all cases, transplant physicians, nephrologists, infectious disease physicians, hepatologists, nurses, pharmacists, nutritionists, and clinical psychologists collaborated to discuss and share medical problems and sociopsychological backgrounds of the patients. There was no rejection, CD4+ lymphocyte counts were maintained, and there was no increase in viral load post-surgery. Information sharing among various departments has continued post-surgery, kidney function has improved, and no increase in viral load has been identified on follow-up.

Conclusions

Kidney transplantation is the kidney replacement therapy of choice for HIV-infected patients with CKD. Specialized support is required for kidney transplantation, including coordinating immunosuppressive therapy to avoid rejection, learning about drug interactions, and providing sociopsychological support. Multidisciplinary collaboration is important to ensure safe and smooth kidney transplantation care for HIV-infected patients.

Reversibility of Central Nervous System Adverse Events in Course of Art

The purpose of this study is to evaluate the frequency of central nervous system adverse events (CNS-AE) on dolutegravir (DTG) and non-DTG containing ART, and their reversibility, in the observational prospective SCOLTA cohort. Factors associated with CNS-AE were estimated using a Cox proportional-hazards model. 4939 people living with HIV (PLWH) were enrolled in DTG (n = 1179) and non-DTG (n = 3760) cohorts. Sixty-six SNC-AE leading to ART discontinuation were reported, 39/1179 (3.3%) in DTG and 27/3760 (0.7%) in non-DTG cohort. PLWH naïve to ART, with higher CD4 + T count and with psychiatric disorders were more likely to develop a CNS-AE. The risk was lower in non-DTG than DTG-cohort (aHR 0.33, 95% CI 0.19−0.55, p < 0.0001). One-year follow-up was available for 63/66 PLWH with CNS-AE. AE resolution was reported in 35/39 and 23/24 cases in DTG and non-DTG cohorts, respectively. The probability of AE reversibility was not different based on ART class, sex, ethnicity, CDC stage, or baseline psychiatric disorder. At the same time, a lower rate of event resolution was found in PLWH older than 50 years (p = 0.017). In conclusion, CNS-AE leading to ART discontinuation was more frequent in DTG than non-DTG treated PLWH. Most CNS-AE resolved after ART switch, similarly in both DTG and non-DTG cohorts.

Association of high SARS-CoV-2 RNAemia with diabetes and mortality in COVID-19 critically ill patient

It has been suggested that during the period of respiratory worsening of severe COVID-19 patients, viral replication plays a less important role than inflammation. Using the droplet-based digital PCR (ddPCR) for precise quantification of plasma SARS-CoV-2 viral load (SARS-CoV-2 RNAemia), we investigated the relationship between plasma viral load, comorbidities, and mortality of 122 critically ill COVID-19 patients. SARS-CoV-2 RNAemia was detected by ddPCR in 90 (74%) patients, ranging from 70 to 213,152 copies per mL. A high (>1 000 copies/ml) or very high (>10,000 copies/ml) SARS-Cov-2 RNAemia was observed in 46 patients (38%), of which 26 were diabetic. Diabetes was independently associated with a higher SARS-CoV-2 RNAemia. In multivariable logistic regression models, SARS-CoV-2 RNAemia was strongly and independently associated with day-60 mortality. Early initiation of antiviral therapies might be considered in COVID-19 critically ill patients with high RNAemia.

•

Plasma SARS-CoV-2 RNA was detected in 90 of 122 COVID-19 critically ill patients

•

Plasma SARS-CoV-2 RNA was high (>1000 copies per mL) in 46 patients

•

Diabetic patients had significantly higher levels of plasma SARS-CoV-2 RNA

•

Plasma SARS-CoV-2 RNA levels were independently associated with day-60 mortality

DOLAVI Real-Life Study of Dolutegravir Plus Lamivudine in Naive HIV-1 Patients (48 Weeks)

Brief: Real-world data in naïve HIV-1 patients demonstrate that dolutegravir plus lamivudine in a multiple tablet regimen is effective, safe, and satisfactory; it causes moderately increasing weight and abdominal circumference and is administrable on a test-and-treat strategy. Background: Our objectives were to determine the real-life effectiveness and safety of DT with dolutegravir (50 mg/QD) plus lamivudine (300 mg/QD) in a multiple-tablet regimen (MTR) in naïve PLHIV followed up for 48 weeks and to evaluate the compliance and satisfaction of patients. Material and methods: An open, single-arm, multicenter, non-randomized clinical trial from May 2019 through September 2020 with a 48-week follow-up. Results: The study included 88 PLHIV patients (87.5% male) with a mean age of 35.9 years; 76.1% were MSM patients. The mean baseline CD4 was 516.4 cells/uL, with a viral load (VL) of 4.49 log10, and 11.4% were in the AIDS stage. DT started within 7 days of first specialist consultation in all patients and the same day in 84.1%; 3.4% had baseline resistance mutations (K103N, V106I + E138A, and V108I); 12.5% were lost to follow-up. At week 48, 86.3% had VL < 50 cop/uL by intention-to-treat analysis and 98.7% by per-protocol (PP) analysis. Virological failure (VF) was recorded in 1.1%, with no resistance mutation. One blip was detected in 5.2% without VF. Three reported anxiety, dizziness, and cephalgia, respectively, at week 4 and one reported insomnia at week 24; none reported adverse events at week 48. The mean weight was 4 kg higher at 48 weeks (p = 0.0001) and abdominal circumference 3 cm larger at 24 weeks (p = 0.022). No forgetfulness occurred in 98.7% of patients. Patient satisfaction was 90/100 at 4, 24, and 48 weeks. Conclusion: Real-world data demonstrate that dolutegravir plus lamivudine in MTR is effective, safe, and satisfactory, moderately increasing weight and abdominal circumference and administrable on a test-and-treat strategy.
