Long-term impact of immediate versus deferred antiretroviral therapy on kidney health in people with HIV.

People with human immunodeficiency virus (HIV) are at risk for chronic kidney disease (CKD) due to HIV and antiretroviral therapy (ART) nephrotoxicity. Immediate ART initiation reduces mortality and is now the standard of care, but the long-term impact of prolonged ART exposure on CKD is unknown. To evaluate this, the Strategic Timing of Antiretroviral Treatment (START) trial randomized 4,684 ART-naïve adults with CD4 cell count under 500 cells/mm3 to immediate versus deferred ART. We previously reported a small but statistically significantly greater decline in estimated glomerular filtration rate (eGFR) over a median of 2.1 years in participants randomized to deferred versus immediate ART. Here, we compare the incidence of CKD events and changes in eGFR and urine albumin/creatinine ratio (UACR) in participants randomized to immediate versus deferred ART during extended follow-up. Over a median of 9.3 years, eight participants experienced kidney failure or kidney-related death, three in the immediate and five in the deferred ART arms, respectively. Over a median of five years of more comprehensive follow-up, the annual rate of eGFR decline was 1.19 mL/min/1.73m2/year, with no significant difference between treatment arms (difference deferred - immediate arm 0.055; 95% confidence interval -0.106, 0.217 mL/min/1.73m2). Results were similar in models adjusted for baseline covariates associated with CKD, including UACR and APOL1 genotype. Similarly, there was no significant difference between treatment arms in incidence of confirmed UACR 30 mg/g or more (odds ratio 1.13; 95% confidence interval 0.85, 1.51). Thus, our findings provide the most definitive evidence to date in support of the long-term safety of early ART with respect to kidney health.

Prevalence of people living with multidrug-resistant HIV and limited treatment options in Spain.

OBJECTIVES: Our aim was to determine the prevalence and characteristics of people with HIV on antiretroviral therapy (ART) with multidrug resistance (MDR; confirmed resistance to three or more [or resistance to two or more plus contraindication to one or more] core ART classes) and limited treatment options (LTOs) in Spain. METHODS: This was an observational, retrospective, multicentre, cross-sectional chart review study undertaken in five reference Spanish centres. Participants were people with HIV on ART with MDR and LTOs (detectable viral load [HIV-RNA >200 copies/mL], treatment-limiting drug-drug interaction [DDI], or intolerance precluding the use of one or more ART classes). Prevalence, demographic/clinical characteristics, and treatment options were assessed. Logistic regression analyses were used to identify MDR-associated variables. RESULTS: Of 14 955 screened people with HIV, 69 (0.46%) presented with MDR and 23 (0.15%) had LTOs. The population analysed was 73.9% male with a median age of 54.0 years; the median time since HIV diagnosis was 26.5 years, and median CD4+ cell count was 511.0 cells/µL. The only factor significantly associated with MDR (univariate analysis) was CD4+ cell count. Injection drug use was the most common transmission route. Comorbidities (mainly endocrine and cardiovascular disorders; 34.8% affecting HIV management) and concomitant treatments were frequent. No recent opportunistic infections were reported. Patients had been exposed to the following ART: nucleoside analogue reverse transcriptase inhibitors (100%), protease inhibitors (95.6%), non-nucleoside analogue reverse transcriptase inhibitors (87.0%), and integrase strand transfer inhibitors (82.6%). The available fully active drugs were dolutegravir (39.1%), bictegravir (30.4%), and raltegravir (21.7%). CONCLUSIONS: The prevalence of people with HIV with MDR and LTOs in Spain is very low, with approximately half of those studied not exhibiting virological suppression. Low CD4+ cell counts were associated with MDR. These findings may help address the impact and treatment needs of these patients and prevent clinical progression and transmission of MDR HIV.

Improvements in Patient-Reported Outcomes After 12 Months of Maintenance Therapy With Cabotegravir + Rilpivirine Long-Acting Compared With Bictegravir/Emtricitabine/Tenofovir Alafenamide in the Phase 3b SOLAR Study.

SOLAR (NCT04542070; registered 2020-09-09) is a Phase 3b study that demonstrated the noninferior virological efficacy of switching to cabotegravir + rilpivirine long-acting (CAB + RPV LA) dosed every 2 months vs. continuing daily oral bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) over 12 months. Participants were randomised (2:1) to switch to CAB + RPV LA or to continue BIC/FTC/TAF. Patient-reported endpoints included treatment preference, treatment satisfaction (12-item HIV Treatment Satisfaction Questionnaire status version), acceptability of injections (Perception of Injection questionnaire [acceptability domain]) and three single-item questions exploring psychological challenges related to HIV treatment (fear of disclosure, adherence-related anxiety and reminder of HIV status). Of 670 participants, 447 participants switched to CAB + RPV LA and 223 continued BIC/FTC/TAF. Overall, 18% were female, median age was 37 years and 31% were non-White. At Month 12, CAB + RPV LA significantly improved treatment satisfaction vs. BIC/FTC/TAF (mean [95% confidence interval (CI)] change: + 3.36 [2.59, 4.13] vs. -1.59 [-2.71, -0.47]; p < 0.001). At Month 12, a higher proportion of CAB + RPV LA arm participants reported improvements across the psychological challenges related to HIV treatment questions compared with BIC/FTC/TAF participants. Participants indicating ≥ 1 psychological challenge at baseline experienced a statistically significant and clinically meaningful improvement in treatment satisfaction after 12 months of CAB + RPV LA vs. continuing BIC/FTC/TAF (adjusted difference [95% CI]: 7.96 [5.65, 10.26]; p < 0.001). Most (90%, 382/425) questionnaire respondents preferred CAB + RPV LA vs. BIC/FTC/TAF (5%, 21/425). Switching to CAB + RPV LA was associated with significantly improved treatment satisfaction and relief from the fear of disclosure, anxiety surrounding adherence and reminder of HIV status.

RESUMEN: SOLAR (NCT04542070; registrado el 09-09-2020) es un estudio de fase IIIb que ha demostrado la eficacia virológica no inferior de cambiar a cabotegravir+rilpivirina de acción prolongada (CAB+RPV LA) administrado cada 2 meses frente a continuar con la administración oral diaria de bictegravir/emtricitabina/tenofovir alafenamida (BIC/FTC/TAF) durante 12 meses. Los participantes fueron asignados de forma aleatoria (2:1) al grupo de cambio a CAB+RPV LA o de continuación con BIC/FTC/TAF. Los parámetros declarados por los pacientes incluían la preferencia del tratamiento, la satisfacción del tratamiento (versión del estado del cuestionario de satisfacción del tratamiento de VIH de 12 preguntas), la aceptación de las inyecciones (cuestionario de percepción de las inyecciones [dominio de aceptación]) y tres preguntas individuales que analizaban los problemas psicológicos relacionados con el tratamiento del VIH (miedo a la revelación, ansiedad relacionada con el cumplimiento terapéutico y recordatorio del estado del VIH). De los 670 participantes, 447 participantes cambiaron a CAB+RPV LA y 223 continuaron con BIC/FTC/TAF. En general, el 18 % eran mujeres, el promedio de edad era de 37 años y el 31 % no eran blancos. En el mes 12, el tratamiento con CAB+RPV LA aumentó considerablemente la satisfacción del tratamiento frente al BIC/FTC/TAF (cambio [intervalo de confianza (IC) del 95 %] medio: +3.36 [2.59; 4.13] frente a ­1.59 [­2.71; ­0.47]; p<0.001). En el mes 12, una mayor proporción de participantes del grupo de CAB+RPV LA declararon mejoras en todos los problemas psicológicos relacionados con las preguntas sobre el tratamiento del VIH en comparación con los participantes del grupo de BIC/FTC/TAF. Los participantes que indicaron ≥ 1 problema psicológico en el inicio experimentaron una mejora importante estadísticamente y significativa clínicamente con respecto a la satisfacción del tratamiento al cabo de 12 meses del cambio a CAB+RPV LA frente a la continuación con BIC/FTC/TAF (diferencia ajustada [IC del 95 %]: 7.96 [5.65; 10.26]; p<0.001). La mayoría de encuestados (el 90 %, 382/425) preferían CAB+RPV LA frente a BIC/FTC/TAF (el 5 %, 21/425). El cambio a CAB+RPV LA se asoció a un aumento considerable de la satisfacción del tratamiento y al alivio del miedo a la revelación, la ansiedad en torno al cumplimiento terapéutico y el recordatorio del estado del VIH.
