RESUMEN

BACKGROUND: Incidence of anal cancer (AC) caused by persistent human papillomavirus (HPV) infection has risen in the last years in men who have sex with men (MSM) living with HIV. There is consensus that this population should be screened for anal precancerous lesions, but the role of HPV DNA testing in AC screening programmes is still under debate. OBJECTIVES: This study employed two molecular test to detect anal HPV DNA and compared assay performance and prognostic value for the diagnosis of histology proven high-grade intraepithelial anal lesions. METHODS: MSM living with HIV attended their regular check-up visits consisting of detection of anal HPV infection, anal cytology, digital anorectal examination and high resolution anoscopy. HPV DNA was detected using Hybrid Capture 2 High-Risk test (HC2, total assay) and LINEAR ARRAY HPV Genotyping Test (LA, type-specific assay) RESULTS: Among 274 participant, prevalence of HPV DNA was 48.5% by HC2 and 89.4% by LA. HPV16 (30.6%) and HPV6 (19.6%) were the most common genotypes identified. Prevalence of multiple HPV infections was 56.2%. Agreement between HPV DNA assays was 75.2% (κ=0.51; 95% CI 0.42 to 0.60). Total HPV detection demonstrated high sensitivity (90%; 95% CI 68.3 to 98.8) and moderate specificity (58.4%; 95% CI 50.2 to 66.3), while type-specific HPV16/18 genotyping provided an increase in specificity and showed the highest area under the curve (0.81; 95% CI 0.74 to 0.89) and Youden's index (0.63). CONCLUSIONS: Both methodologies identified a high prevalence of anal HPV infection and multiple HPV infections in MSM living with HIV, showing a moderate overall agreement between them. Either total HPV detection or type-specific HPV16/18 detection together with a threshold ≥atypical squamous cells of undetermined significance for abnormal cytology showed an acceptable diagnostic accuracy.

RESUMEN

BACKGROUND: Older People Living with HIV (OPWH) combine both aging and HIV-infection features, resulting in ageism, stigma, social isolation, and low quality of life. This context brings up new challenges for healthcare professionals, who now must aid patients with a significant comorbidity burden and polypharmacy treatments. OPWH opinion on their health management is hardly ever considered as a variable to study, though it would help to understand their needs on dissimilar settings. METHODS: We performed a cross-sectional, comparative study including patients living with HIV aged ≥50 years old from multiple centers worldwide and gave them a survey addressing their perception on overall health issues, psychological problems, social activities, geriatric conditions, and opinions on healthcare. Data was analyzed through Chisquared tests sorting by geographical regions, age groups, or both. RESULTS: We organized 680 participants data by location (Center and South America [CSA], Western Europe [WE], Africa, Eastern Europe and Israel [EEI]) and by age groups (50- 55, 56-65, 66-75, >75). In EEI, HIV serostatus socializing and reaching undetectable viral load were the main problems. CSA participants are the least satisfied regarding their healthcare, and a great part of them are not retired. Africans show the best health perception, have financial problems, and fancy their HIV doctors. WE is the most developed region studied and their participants report the best scores. Moreover, older age groups tend to live alone, have a lower perception of psychological problems, and reduced social life. CONCLUSIONS: Patients' opinions outline region- and age-specific unmet needs. In EEI, socializing HIV and reaching undetectable viral load were the main concerns. CSA low satisfaction outcomes might reflect high expectations or profound inequities in the region. African participants results mirror a system where general health is hard to achieve, but HIV clinics are much more appealing to them. WE is the most satisfied region about their healthcare. In this context, age-specific information, education and counseling programs (i.e. Patient Reported Outcomes, Patient Centered Care, multidisciplinary teams) are needed to promote physical and mental health among older adults living with HIV/AIDS. This is crucial for improving health-related quality of life and patient's satisfaction.

RESUMEN

Doravirine (DOR) concentrations and HIV-1 RNA were evaluated in genital fluids from adults with HIV on stable therapy who switched to DOR + FTC/TAF. High protein-unbound DOR concentrations were observed in both seminal plasma and cervicovaginal fluid. DOR + FTC/TAF maintained viral suppression in genital fluids in all but 1 participant.

RESUMEN

We determined total and unbound concentrations of doravirine (DOR) in cerebrospinal fluid and blood plasma. Total and unbound DOR concentrations in cerebrospinal fluid exceeded the half-maximal effective concentration against wild-type virus (5.1 ng/mL) in all patients, suggesting that DOR may contribute to inhibit viral replication in this compartment.

RESUMEN

BACKGROUND: The aim of this study was to investigate whether switching from a ritonavir-boosted PI-based regimen to a dolutegravir-based regimen improved the atherogenic properties of LDL particles in patients with HIV. METHODS: This was a substudy of the NEAT022 study (ClinicalTrials.gov NCT02098837). Adults with HIV with a Framingham score >10% or aged >50 years and being treated with a stable boosted PI-based regimen were randomized to either switch to dolutegravir or continue with boosted PI. At baseline and Week 48, we assessed atherogenic LDL properties: LDL particle size and phenotype (A, intermediate, B), oxidized LDL (ox-LDL) and lipoprotein-associated phospholipase A2 (Lp-PLA2) activity. RESULTS: Eighty-six participants (dolutegravir 44; PI 42) were included. Participants had a median (IQR) age of 54 (51-57) years and 79.1% were male. In the dolutegravir arm, after 48 weeks, we observed: (1) an increase in LDL size [median 1.65 Š(IQR -0.60 to 4.20); P = 0.007], correlated with the decrease in triglyceride concentration [Spearman correlation = -0.352 (P = 0.001)], with a corresponding decrease of subjects with atherogenic LDL phenotype B (36.4% to 20.5%; P = 0.039); (2) a decrease in Lp-PLA2 activity [median 1.39 µmol/min/mL (IQR -2.3 to 0.54); P = 0.002]; and (3) a decrease in ox-LDL [median 14 U/L (IQR -102 to 13); P = 0.006]. In the PI arm, none of these favourable lipid modifications was observed. CONCLUSIONS: Forty-eight weeks after switching from a PI-based to a dolutegravir-based regimen, patients with Framingham score >10% or aged >50 years showed improvement of several atherogenic lipid features, including LDL particle phenotype, ox-LDL and Lp-PLA2.

RESUMEN

BACKGROUND: In addition to traditional cardiovascular (CV) risk factors, antiretroviral therapy, lifestyle, and human immunodeficiency virus (HIV)-related factors may contribute to future CV events in persons with HIV (PWH). METHODS: Among participants in the global REPRIEVE randomized trial, we characterized demographics and HIV characteristics relative to ACC/AHA pooled cohort equations (PCE) for atherosclerotic CV disease predicted risk and CV health evaluated by Life's Simple 7 (LS7; includes smoking, diet, physical activity, body mass index, blood pressure, total cholesterol, and glucose). RESULTS: Among 7382 REPRIEVE participants (31% women, 45% Black), the median PCE risk score was 4.5% (lower and upper quartiles Q1, Q3: 2.2, 7.2); 29% had a PCE score <2.5%, and 9% scored above 10%. PCE score was related closely to known CV risk factors and modestly (<1% difference in risk score) to immune function and HIV parameters. The median LS7 score was 9 (Q1, Q3: 7, 10) of a possible 14. Only 24 participants (0.3%) had 7/7 ideal components, and 36% had ≤2 ideal components; 90% had <5 ideal components. The distribution of LS7 did not vary by age or natal sex, although ideal health was more common in low sociodemographic index countries and among Asians. Poor dietary and physical activity patterns on LS7 were seen across all PCE scores, including the lowest risk categories. CONCLUSIONS: Poor CV health by LS7 was common among REPRIEVE participants, regardless of PCE. This suggests a critical and independent role for lifestyle interventions in conjunction with conventional treatment to improve CV outcomes in PWH. Clinical Trials Registration: NCT02344290. AIDS Clinical Trials Group study number: A5332.

RESUMEN

BACKGROUND: In 2012, the central government of Spain enacted Royal Decree-Law (RDL) 16/2012 and Royal Decree (RD) 1192/2012, which abolished universal healthcare coverage, thus limiting access to care for undocumented immigrants. Free health care was also no longer granted to anyone who has never been employed. In this context, this study investigated the prevalence of late HIV diagnoses (LHDs) among immigrants living in Spain vs. native-born Spaniards. METHODS: Data (n = 5943) from the 2010 to 2015 Cohort of the Spanish AIDs Research Network were used, including HIV-positive and antiretroviral therapy (ART)-naïve patients throughout Spain. Multivariate logistic models were fitted to compare the prevalence of LHD among the groups, adjusting for covariates. RESULTS: The prevalence of LHD in the total sample was 39.5%. Compared with native-born Spaniards (n = 4445), immigrants (n = 1488) were more likely to have LHD (37.4% vs. 45.7%, respectively; P < 0.001). Multivariate analysis showed that the prevalence ratio of LHD among immigrants vs. native-born Spaniards was 1.15 [95% confidence interval (CI), 1.02-1.28], after adjusting for covariates. This disparity widened from 2010 to 2011 (APR = 1.14, 95% CI, 1.02-1.29) to 2012-15 (APR = 1.28, 95% CI, 1.17-1.39), although the change was not statistically significant. CONCLUSIONS: Immigrants in Spain had a higher risk of LHD compared with native-born counterparts. LHD is an important healthcare marker due to the positive benefits of early HIV diagnosis, including prevention, improvements in health outcomes and decreases in overall cost of treatment. More research is needed on the causes of the disparity and potential social and policy interventions to reduce the prevalence of LHD among immigrants.

RESUMEN

OBJECTIVE: HIV-positive men who have sex with men (MSM) are a vulnerable group for anal cancer (AC), a cancer with a well-described precursor lesion, which can be detected early in screening programs using anal liquid-based cytology (aLBC). We aim to compare two aLBC sample collection devices: cytology brush (CB) and Dacron swab (DS). METHODS: Retrospective analysis of two consecutive study periods, the first using CB and the second DS. Participants underwent an aLBC, a human papillomavirus (HPV) DNA test and a high-resolution anoscopy (HRA), and a biopsy was performed for suspicious lesions. The sensitivity and specificity of aLBC, area under the receiver operating characteristic (ROC) curve (AUC), and concordance between cytology and HRA were assessed using Cohen's kappa coefficient. RESULTS: A total of 239 participants were enrolled (CB group, 120; DS group, 119). aLBC was benign in 46% of samples, and high-grade squamous intraepithelial lesion (HSIL) was detected in 11.7%. Prevalence of biopsy-proven HSIL was 15.3%. No differences in cytological and histological results were observed between the groups. aLBC-HRA concordance was weak for benign results (CB group, k = 0.309; DS group, k = 0.350) as well as for HSIL (k = 0.321 and 0.387, respectively). Sensitivity and specificity were 100% and 51.4%, respectively, in the CB group and 88% and 54.3% in the DS group (AUC = 0.711 and 0.759, respectively, P-value = .514). Representation of the transformation zone (TZ) was adequate in 83.3% of samples in the CB group and 50.4% in the DS group (P-value <.001). CONCLUSION: Our data suggest that both devices had similar accuracy to detect anal HSIL, although samples collected with CB are more likely to have an adequate TZ representation, the presence of which could be an indicator of sample quality.

RESUMEN

We determined total and unbound concentrations of bictegravir (BIC) in cerebrospinal fluid (CSF) in 15 asymptomatic, virologically suppressed patients. The median plasma and CSF total BIC concentrations were 1837.1 ng/mL (interquartile range [IQR], 1237.2-2586.7) and 6.9 (IQR, 4.8-10.9), respectively. Median unbound BIC concentration was 2.48 ng/mL (IQR, 1.6-3.7). Total and unbound BIC CSF concentrations were above the half-maximal effective concentration value in all patients, and all subjects had human immunodeficiency virus viral suppression in plasma and CSF. Bictegravir may contribute to inhibit viral replication in this compartment.

RESUMEN

BACKGROUND: Switching from boosted PIs to dolutegravir in virologically suppressed HIV-infected patients with high cardiovascular risk significantly decreased total cholesterol and other proatherogenic lipid fractions at 48 weeks. The impact of this strategy on subclinical cardiovascular disease is unknown. METHODS: NEAT022 is a European, multicentre, open-label, randomized, non-inferiority trial. HIV-infected adults aged >50 years or with a Framingham score >10% were eligible if plasma HIV RNA was <50 copies/mL for >24 weeks on a boosted PI-based regimen. Patients were randomized 1:1 to switch from boosted PIs to dolutegravir or to continue on boosted PIs. Common carotid arteries intima-media thickness (CIMT) and pulse wave velocity (PWV) were measured following a standardized protocol in a subgroup of NEAT022 study participants at baseline and at Week 48. RESULTS: One hundred and fifty-six patients participated in the ultrasonography and arterial stiffness substudies, respectively. In each substudy, population characteristics did not differ between arms and matched those of the main study. At 48 weeks, patients who switched to dolutegravir had lower mean progression of both right (+4 versus +14.6 µm) and left (-6.1 versus +1.6 µm) CIMT and also a smaller increase in mean PWV (+0.18 versus +0.39 m/s) than patients continuing on boosted PIs, although differences were not statistically significant. CIMT trends were consistent across Framingham score, age and country. Inconsistent effects were seen in arterial stiffness. CONCLUSIONS: Relative to continuing on boosted PIs, switching to dolutegravir in virologically suppressed patients with high cardiovascular risk showed consistent favourable although non-significant trends on CIMT progression at 48 weeks.

RESUMEN

Background: Both immediate and deferred switching from a ritonavir-boosted protease inhibitor (PI/r)-based regimen to a dolutegravir (DTG)-based regimen may improve lipid profile. Methods: European Network for AIDS Treatment 022 Study (NEAT022) is a European, open-label, randomized trial. Human immunodeficiency virus (HIV)-infected adults aged ≥50 years or with a Framingham score ≥10% were eligible if HIV RNA was <50 copies/mL. Patients were randomized to switch from PI/r to DTG immediately (DTG-I) or to deferred switch at week 48 (DTG-D). Week 96 endpoints were proportion of patients with HIV RNA <50 copies/mL, percentage change of lipid fractions, and adverse events (AEs). Results: Four hundred fifteen patients were randomized: 205 to DTG-I and 210 DTG-D. The primary objective of noninferiority at week 48 was met. At week 96, treatment success rate was 92.2% in the DTG-I arm and 87% in the DTG-D arm (difference, 5.2% [95% confidence interval, -.6% to 11%]). There were 5 virological failures in the DTG-I arm and 5 (1 while on PI/r and 4 after switching to DTG) in the DTG-D arm without selection of resistance mutations. There was no significant difference in terms of grade 3 or 4 AEs or treatment-modifying AEs. Total cholesterol and other lipid fractions (except high-density lipoprotein) significantly (P < .001) improved both after immediate and deferred switching to DTG overall and regardless of baseline PI/r strata. Conclusions: Both immediate and deferred switching from a PI/r to a DTG regimen in virologically suppressed HIV-infected patients ≥50 years old or with a Framingham score ≥10% was highly efficacious and well tolerated, and improved the lipid profile.

RESUMEN

BACKGROUND: It is unknown if tenofovir disoproxil fumarate (TDF), which is often coformulated with the lipid-neutral emtricitabine (FTC), has a lipid-lowering effect. METHODS: We performed a randomized, crossover, double-blind, placebo-controlled clinical trial on human immunodeficiency virus type 1 (HIV-1)-infected subjects with HIV-1 RNA < 50 copies/mL during ≥6 months on stable darunavir/ritonavir (800/100 mg once daily) or lopinavir/ritonavir (400/100 mg twice daily) monotherapy, fasting total cholesterol (TC) ≥200 mg/dL or low-density lipoprotein cholesterol (LDL-c) ≥130 mg/dL, and no lipid-lowering drugs. In arm 1, TDF/FTC was added for 12 weeks, followed by 12 weeks of placebo (washout) and 12 additional weeks of placebo (placebo period). Subjects in arm 2 added placebo for 12 weeks (placebo period) followed by TDF/FTC for 12 weeks and placebo for 12 additional weeks (washout). The primary endpoint was change in median fasting TC levels. RESULTS: Of 46 subjects enrolled, 56% received darunavir/ritonavir and 44% lopinavir/ritonavir. Exposure to TDF/FTC reduced TC from 234 to 205 mg/dL (P < .001), LDL-c from 155 to 128 mg/dL (P < .001), and high-density lipoprotein cholesterol (HDL-c) from 50.3 to 44.5 mg/dL (P < .001). It also decreased the proportion of subjects with fasting TC ≥200 mg/dL from 86.7% to 56.8% (P = .001), and LDL-c ≥130 mg/dL from 87.8% to 43.9% (P < .001). After 12 weeks, TDF/FTC exposure was associated with lower TC and LDL-c levels than placebo (P = .001 and P = .002, respectively). The TC/HDL-c ratio and triglyceride levels did not change with TDF/FTC exposure. CONCLUSIONS: Coformulated TDF/FTC has an intrinsic lipid-lowering effect, likely attributable to TDF. CLINICAL TRIALS REGISTRATION: NCT01458977.

RESUMEN

OBJECTIVES: To assess LDL subfraction phenotype and lipoprotein-associated phospholipase A2 (Lp-PLA2) in naive HIV-infected patients starting atazanavir/ritonavir or darunavir/ritonavir plus tenofovir/emtricitabine. METHODS: This was a substudy of a multicentre randomized study. Standard lipid parameters, LDL subfraction phenotype (by gradient gel electrophoresis) and Lp-PLA2 activity (by 2-thio-PAF) were measured at baseline and weeks 24 and 48. Multivariate regression analysis was performed. Results are expressed as the median (IQR). RESULTS: Eighty-six (atazanavir/ritonavir, n=45; darunavir/ritonavir, n=41) patients were included: age 36 (31-41) years; 89% men; CD4 319 (183-425) cells/mm(3); and Framingham score 1% (0%-2%). No differences in demographics or lipid measurements were found at baseline. At week 48, a mild but significant increase in total cholesterol and HDL-cholesterol was observed in both arms, whereas LDL cholesterol increased only in the darunavir/ritonavir arm and triglycerides only in the atazanavir/ritonavir arm. The apolipoprotein A-I/apolipoprotein B ratio increased only in the atazanavir/ritonavir arm. At week 48, the LDL subfraction phenotype improved in the darunavir/ritonavir arm (increase in LDL particle size and in large LDL particles), whereas it worsened in the atazanavir/ritonavir arm (increase in small and dense LDL particles, shift to a greater prevalence of phenotype B); the worsening was related to the greater increase in triglycerides in the atazanavir/ritonavir arm. No changes in total Lp-PLA2 activity or relative distribution in LDL or HDL particles were found at week 48 in either arm. CONCLUSIONS: In contrast with what occurred in the atazanavir/ritonavir arm, the LDL subfraction phenotype improved with darunavir/ritonavir at week 48. This difference was associated with a lower impact on plasma triglycerides with darunavir/ritonavir.

RESUMEN

Background: Effective antiretroviral therapy (ART) has substantially reduced acquired immunodeficiency syndrome (AIDS)-related deaths, shifting the focus to non-AIDS conditions in people living with human immunodeficiency virus (HIV) (PLWH). We examined mortality trends and predictors of AIDS- and non-AIDS mortality in the Population HIV Cohort from Catalonia and Balearic Islands (PISCIS) cohort of PLWH from 1998 to 2020. Methods: We used a modified Coding Causes of Death in HIV protocol, which has been widely adopted by various HIV cohorts to classify mortality causes. We applied standardized mortality rates (SMR) to compare with the general population and used competing risks models to determine AIDS-related and non-AIDS-related mortality predictors. Results: Among 30 394 PLWH (81.5% male, median age at death 47.3), crude mortality was 14.2 per 1000 person-years. All-cause standardized mortality rates dropped from 9.6 (95% confidence interval [CI], 8.45-10.90) in 1998 through 2003 to 3.33 (95% CI, 3.14-3.53) in 2015 through 2020, P for trend = .0001. Major causes were AIDS, non-AIDS cancers, cardiovascular disease, AIDS-defining cancers, viral hepatitis, and nonhepatitis liver disease. Predictors for AIDS-related mortality included being aged ≥40 years, not being a man who have sex with men, history of AIDS-defining illnesses, CD4 < 200 cells/µL, ≥2 comorbidities, and nonreceipt of ART. Non-AIDS mortality increased with age, injection drug use, heterosexual men, socioeconomic deprivation, CD4 200 to 349 cells/µL, nonreceipt of ART, and comorbidities, but migrants had lower risk (adjusted hazard risk, 0.69 [95% CI, .57-.83]). Conclusions: Mortality rates among PLWH have significantly decreased over the past 2 decades, with a notable shift toward non-AIDS-related causes. Continuous monitoring and effective management of these non-AIDS conditions are essential to enhance overall health outcomes.

RESUMEN

Human Papillomavirus (HPV) prophylactic vaccination has proven effective in preventing new infections, but it does not treat existing HPV infections or associated diseases. Hence, there is still an important reservoir of HPV in adults, as vaccination programs are mainly focused on young women. The primary objective of this non-randomized, open-label trial is to evaluate if a 3-dose regimen of Gardasil-9 in HPV16/18-positive women could reduce the infective capacity of their body fluids. We aim to assess if vaccine-induced antibodies could neutralize virions present in the mucosa, thus preventing the release of infective particles and HPV transmission to sexual partners. As our main endpoint, the E1^E4-HaCaT model will be used to assess the infectivity rate of cervical, anal and oral samples, obtained from women before and after vaccination. HPV DNA positivity, virion production, seroconversion, and the presence of antibodies in the exudates, will be evaluated to attribute infectivity reduction to vaccination. Our study will recruit two different cohorts (RIFT-HPV1 and RIFT-HPV2) of non-vaccinated adult women. RIFT-HPV1 will include subjects with an HPV16/18 positive cervical test and no apparent cervical lesions or cervical lesions eligible for conservative treatment. RIFT-HPV2 will include subjects with an HPV16/18 positive anal test and no apparent anal lesions or anal lesions eligible for conservative treatment, as well as women with an HPV16/18 positive cervical test and HPV-associated vulvar lesions. Subjects complying with inclusion criteria for both cohorts will be recruited to the main cohort, RIFT-HPV1. Three doses of Gardasil-9 will be administered intramuscularly at visit 1 (0 months), visit 2 (2 months) and visit 3 (6 months). Even though prophylactic HPV vaccines would not eliminate a pre-existing infection, our results will determine if HPV vaccination could be considered as a new complementary strategy to prevent HPV-associated diseases by reducing viral spread.

RESUMEN

Objectives: People with HIV (PWH) have a higher cardiovascular risk than the general population. It remains unclear, however, whether the risk of cardiovascular disease (CVD) is higher in late HIV presenters (LP; CD4 ≤ 350 cells/µL at HIV diagnosis) compared to PWH diagnosed early. We aimed to assess the rates of incident cardiovascular events (CVEs) following ART initiation among LP compared to non-LP. Methods: From the prospective, multicentre PISCIS cohort, we included all adult people with HIV (PWH) initiating antiretroviral therapy (ART) between 2005 and 2019 without prior CVE. Additional data were extracted from public health registries. The primary outcome was the incidence of first CVE (ischemic heart disease, congestive heart failure, cerebrovascular, or peripheral vascular disease). The secondary outcome was all-cause mortality after the first CVE. We used Poisson regression. Results: We included 3,317 PWH [26 589.1 person/years (PY)]: 1761 LP and 1556 non-LP. Overall, 163 (4.9%) experienced a CVE [IR 6.1/1000PY (95%CI: 5.3-7.1)]: 105 (6.0%) LP vs. 58 (3.7%) non-LP. No differences were observed in the multivariate analysis adjusting for age, transmission mode, comorbidities, and calendar time, regardless of CD4 at ART initiation [aIRR 0.92 (0.62-1.36) and 0.84 (0.56-1.26) in LP with CD4 count <200 and 200- ≤ 350 cells/µL, respectively, compared to non-LP]. Overall mortality was 8.5% in LP versus 2.3% in non-LP (p < 0.001). Mortality after the CVE was 31/163 (19.0%), with no differences between groups [aMRR 1.24 (0.45-3.44)]. Women vs. MSM and individuals with chronic lung and liver disease experienced particularly high mortality after the CVE [aMRR 5.89 (1.35-25.60), 5.06 (1.61-15.91), and 3.49 (1.08-11.26), respectively]. Sensitivity analyses including only PWH surviving the first 2 years yielded similar results. Conclusion: CVD remains a common cause of morbidity and mortality among PWH. LP without prior CVD did not exhibit an increased long-term risk of CVE compared with non-LP. Identifying traditional cardiovascular risk factors is essential for CVD risk reduction in this population.

RESUMEN

BACKGROUND: We report NP, clinical and laboratory changes in patients switching from EVG/Cobi/FTC/TAF to BIC/FTC/TAF in clinical practice. METHODS: A group of subjects switching from EVG/Cobi/FTC/TAF to BIC/F/TAF was prospectively followed. A validated sleep quality questionnaire (Pittsburgh Sleep Quality Index), as well as the Hospital Anxiety and Depression Scale (HADS), were administered after 4 weeks from the treatment switch. Adverse events, side effects and discontinuation were recorded at weeks 4 and 24. Pretreatment switch and week 24 body weight and laboratory data were compared. RESULTS: A total of 96 virologically suppressed patients (86% male) were included. All patients received EVG/Cobi/FTC/TAF at least 1 year before the treatment switch. Median (IQR) nadir CD4 was 367 (263). The most common comorbidities were dyslipidemia, HTA and diabetes, 26%, 14% and 7%, respectively. Depression was reported by 8%. Five patients discontinued BIC/FTC/TAF before week 4 due to intolerance (2 insomnia, 1 headache and 2 GI symptoms). No changes in sleep quality, anxiety and depression outcomes were observed at week 4 (p = 0.1, p = 0.1 and p = 0.3, respectively). After 6 months, the median body weight change was statistically significant (0.6 kg, p = 0.003). All patients maintained HIV suppression. CONCLUSION: Except in a few cases, sleep quality, anxiety and depression symptoms remain stable in HIV virologically suppressed patients on EVG/Cobi/FTC/TAF who switch to BIC/F/TAF. NPAEs are mild and tend to occur in those with previous neuropsychiatric symptoms. Weight gain tends to be small but statistically significant. Long-term follow-up in "real-life" cohorts would be needed to confirm these findings.

RESUMEN

In this study, we aim to explore the effects on lipids of integrase strand transfer inhibitors (INSTIs) in naïve and switch randomised controlled trials, and compare them with protease inhibitors (PIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs). We reviewed phase 3/4 randomised clinical trials in the Cochrane and PubMed databases that compare an INSTI with a boosted PI, an NNRTI, or another INSTI plus one or two nucleoside/nucleotide reverse transcriptase inhibitors (NtRTIs) in naïve patients and switching strategies in HIV-infected patients. We reported the baseline plasma concentration of total cholesterol (TC), low and high-density lipoprotein cholesterol (LDL-c, HDL-c), triglycerides (TG), and the TC/HDL-c ratio, as well as the change at weeks 48 and 96, when available. In naïve HIV-infected patients, raltegravir (RAL) and dolutegravir (DTG) have a more favourable lipid profile compared with NNRTI and boosted PI. Elvitegravir (EVG/c) has a superior lipid profile compared with efavirenz and is similar to that observed with ritonavir-boosted atazanavir except in TG, which increases less with EVG/c. In naïve patients, RAL, DTG, and bictegravir (BIC) produce a similar, slight increase in lipids. In switching trials, the regimen change based on a boosted PI or efavirenz to RAL, DTG, or BIC is associated with clinically significant decreases in lipids that are minor when the change is executed on EVG/c. No changes were observed in lipids by switching trials between INSTIs. In summary, RAL, DTG, and BIC have superior lipid profiles compared with boosted-PI, efavirenz, and EVG/c, in studies conducted in naïve participants, and they are associated with a clinically significant decrease in lipoproteins by switching studies.
