RESUMO
BACKGROUND: This was a substudy of a Phase IV, randomized clinical trial (ClinicalTrials.gov identifier: NCT04295460) aiming to compare the activity of dolutegravir/lamivudine versus dolutegravir plus tenofovir alafenamide/emtricitabine (DTGâ+âTAF/FTC) in the male genital tract. METHODS: Participants were asymptomatic adults without sexually transmitted diseases, treatment-naive people living with HIV (PLWH), with CD4+ T cell counts >200 cells/mm3 and plasma HIV-1-RNA levels >5000 and <500â000 copies/mL, randomized (1:1) to DTGâ+âTAF/FTC or dolutegravir/lamivudine. Blood plasma (BP) and seminal plasma (SP) were collected at baseline and Weeks 4, 8, 12 and 24. HIV-1-RNA was measured in BP and SP using the Cobas 6800 system (Roche Diagnostics) with a lower detection limit of 20 copies/mL. The primary efficacy endpoint was the proportion of subjects with undetectable SP HIV-1-RNA at Week 12 by intention-to-treat analysis. RESULTS: Fifteen participants in the DTGâ+âTAF/FTC and 16 in the dolutegravir/lamivudine arms were analysed, with basal SP viral load of 4.81 (4.30-5.43) and 4.76 (4.09-5.23), Pâ=â0.469, respectively. At Week 12, only one participant in each treatment arm had a detectable SP HIV-1-RNA (DTGâ+âTAF/FTC, 141 copies/mL; dolutegravir/lamivudine, 61 copies/mL). Based on the estimated means, there was no significant difference in the decay of HIV-1-RNA in both BP and SP over time between the two arms of treatment (Fâ=â0.452, Pâ=â0.662, and Fâ=â1.147, Pâ=â0.185, respectively). CONCLUSIONS: After 12 weeks of treatment, there were no differences in the percentage of undetectable SP HIV-1-RNA in naive PLWH who started dolutegravir/lamivudine compared with DTGâ+âTAF/FTC.

To evaluate the prevalence of transmitted drug resistance (TDR) to nucleoside and nonnucleoside reverse transcriptase inhibitors (NRTI, NNRTI), protease inhibitors (PI), and integrase strand transfer inhibitors (INSTI) in Spain during the period 2019-2021, as well as to evaluate transmitted clinically relevant resistance (TCRR) to antiretroviral drugs. Reverse transcriptase (RT), protease (Pro), and Integrase (IN) sequences from 1824 PLWH (people living with HIV) were studied. To evaluate TDR we investigated the prevalence of surveillance drug resistance mutations (SDRM). To evaluate TCRR (any resistance level ≥ 3), and for HIV subtyping we used the Stanford v.9.4.1 HIVDB Algorithm and an in-depth phylogenetic analysis. The prevalence of NRTI SDRMs was 3.8% (95% CI, 2.8%-4.6%), 6.1% (95% CI, 5.0%-7.3%) for NNRTI, 0.9% (95% CI, 0.5%-1.4%) for PI, and 0.2% (95% CI, 0.0%-0.9%) for INSTI. The prevalence of TCRR to NRTI was 2.1% (95% CI, 1.5%-2.9%), 11.8% for NNRTI, (95% CI, 10.3%-13.5%), 0.2% (95% CI, 0.1%-0.6%) for PI, and 2.5% (95% CI, 1.5%-4.1%) for INSTI. Most of the patients were infected by subtype B (79.8%), while the majority of non-Bs were CRF02_AG (n = 109, 6%). The prevalence of INSTI and PI resistance in Spain during the period 2019-2021 is low, while NRTI resistance is moderate, and NNRTI resistance is the highest. Our results support the use of integrase inhibitors as first-line treatment in Spain. Our findings highlight the importance of ongoing surveillance of TDR to antiretroviral drugs in PLWH particularly with regard to first-line antiretroviral therapy.

BACKGROUND: Anal squamous cell carcinoma is rare, in general, but considerably higher in HIV-infected men who have sex with men. There is no consensus on the screening of at-risk populations. OBJECTIVE: This study aimed to determine the incidence rates of anal squamous cell carcinoma and the efficacy of a screening program. DESIGN: This is a cohort study (SeVIHanal/NCT03713229). SETTING: This study was conducted at an HIV outpatient clinic in Seville, Spain. PATIENTS: From 2004 to 2017, all patients with at least 1 follow-up visit were analyzed (follow-up group), including a subgroup of men who have sex with men who participated in a specialized program for screening and treating anal neoplasia (SCAN group) from 2011 onward. MAIN OUTCOME MEASURES: The primary outcome measure was the incidence rate of anal squamous cell carcinoma. RESULTS: Of the 3878 people living with HIV included in the follow-up group, 897 were transferred to the SCAN group; 1584 (41%) were men who have sex with men. Total follow-up was 29,228 person-years with an overall incidence rate for anal squamous cell carcinoma of 68.4/100,000 person-years (95% CI, 46.7-97.4). The changes in the incidence rate/100,000 person-years (95% CI) over time was 20.7 (3.40-80.5) for 2004 to 2006, 37.3 (13.4-87.3) for 2007 to 2010, and 97.8 (63.8-144.9) for 2011 to 2017 (p < 0.001). The strongest impact on the incidence of anal squamous cell carcinoma was made by the lack of immune restoration (adjusted incidence rate ratio (95% CI): 6.59 (4.24-10); p < 0.001), the Centers for Disease Control and Prevention category C (adjusted incidence rate ratio (95% CI): 7.49 (5.69-9.85); p < 0.001), and non-men who have sex with men (adjusted incidence rate ratio (95% CI): 0.07 (0.05-0.10); p < 0.001) in a Poisson analysis. From 2010 to 2017, incidence rates (95% CI) of anal squamous cell carcinoma within the SCAN group and the men who have sex with men of the follow-up group were 95.7 (39.6-202) and 201 (101-386)/100,000 person-years (adjusted incidence rate ratio (95% CI): 0.30 (0.23-0.39); p<0.001). The incidence rate ratio (95% CI) including non-men who have sex with men in the follow-up group was 0.87 (0.69-1.11); p = 0.269. LIMITATIONS: Adherence to the visits could not be quantified. CONCLUSION: Incidence rates of anal squamous cell carcinoma in people living with HIV increased significantly from 2004 to 2017, especially in men who have sex with men who were not being screened. Participation in the SCAN program significantly reduced the incidence of anal squamous cell carcinoma in men who have sex with men, in whom focus should be placed, especially on those presenting with Centers for Disease Control and Prevention category C and advanced immune suppression.

The activation phenotypes and functional changes in monocyte subsets during hepatitis C virus (HCV) elimination in HIV/HCV-coinfected patients were evaluated. Twenty-two HIV/HCV-coinfected patients on suppressive combination antiretroviral treatment (cART) achieving HCV elimination after direct-acting antiviral (DAA) therapy and 10 HIV-monoinfected patients were included. The activation phenotype (10 markers) and polyfunctionality (intracellular interleukin-1α [IL-1α], IL-1ß, IL-6, IL-8, tumor necrosis factor alpha [TNF-α], and IL-10 production) in three monocyte subsets (classical, intermediate, and nonclassical) were evaluated by flow cytometry before and at the end of treatment. Cell-associated HIV DNA levels were assayed by droplet digital PCR. After HCV clearance, there was a significant increase in classical monocyte and decreases in intermediate and nonclassical monocyte levels. The levels of the activation markers CD49d, CD40, and CX3CR1 were decreased after treatment in the monocyte subsets, reaching the levels in HIV-monoinfected patients. After lipopolysaccharide (LPS) stimulation, although polyfunctionality significantly decreased in intermediate and nonclassical monocytes, some combinations, such as the IL-1α- (IL-1α-negative) IL-1ß- IL-6+ (IL-6-producing) IL-8- TNF-α- IL-10- combination, were remarkably increased at the end of treatment compared to the control group. Cell-associated HIV DNA levels correlated with activation markers before but not after treatment. HCV clearance after DAA treatment in patients on cART exerts an anti-inflammatory profile on monocyte subsets, activation phenotypes, and polyfunctionality. However, there is not a complete normalization compared with HIV-monoinfected patients.

OBJECTIVES: To analyse whether integrase inhibitor (InSTI)-based regimens achieve better immunological recovery than NNRTI- or boosted PI (bPI)-based regimens as initial ART. METHODS: In a retrospective analysis, we selected patients who initiated ART with two NRTIs plus an InSTI, an NNRTI or a bPI and maintained both the same 'third drug' and an HIV-RNA <50 copies/mL in ≥95% of determinations once undetectable viral load had been achieved. We compared CD4+ count, %CD4+ and CD4+/CD8+ ratio recovery over 2 years. Data were analysed using mixed-effects regression models for repeated measures. RESULTS: Of the 836 patients included, 208, 481 and 147 initiated with InSTI, NNRTI and bPI, respectively. For CD4+, %CD4+ and CD4+/CD8+ two main slopes were identified: from month 0 to month 6, with the highest increments; and from month 6 to month 24, with smaller increases every semester. Although the patients on InSTI achieved undetectable viral load faster, for CD4+ and %CD4+ there were no differences in the slopes of change according to the third drug either for the first phase (P=0.137 and P=0.393, respectively) or from month 6 onwards (P=0.834 and P=0.159, respectively). The increase in CD4+/CD8+ was slightly higher for bPI compared with InSTI (difference of 0.0119, 95% CI 0.0020-0.0205; P=0.018), but clinically negligible. From month 6 onwards, no differences were found between treatment groups (P=0.176). CONCLUSIONS: Immune restoration measured as CD4+ count, %CD4+ and CD4+/CD8+ increases was independent of the third antiretroviral drug class used when given with two NRTIs.

OBJECTIVES: We report the results of the reverse transcriptase (RT)/protease (PR) transmitted drug resistance (TDR) prevalence study in 2018, focusing on doravirine resistance-associated mutations and the differences observed when Stanford or French National Agency for AIDS Research (ANRS)/Spanish Network of AIDS Research (RIS)/IAS-USA resistance interpretation algorithms are used to describe clinically relevant resistance. METHODS: We used the WHO 2009 list to investigate the prevalence of NNRTI, NRTI and PI TDR, in treatment-naive HIV-1-infected patients, adding mutations E138A/G/K/Q/R, V106I, V108I, V179L, G190Q, H221Y, F227C/L/V, M230IDR, L234I, P236L and Y318F in RT. The prevalence of doravirine resistance-associated mutations, as described by Soulie et al. in 2019, was evaluated. Clinically relevant TDR was investigated using the latest versions of ANRS, RIS, IAS-USA and Stanford algorithms. RESULTS: NNRTI mutations were detected in 82 of 606 (13.5%) patients. We found 18 patients (3.0%) with NRTI mutations and 5 patients (0.8%) with PI mutations. We detected 11 patients harbouring doravirine resistance-associated mutations (prevalence of 1.8%). Furthermore, we observed important differences in clinically relevant resistance to doravirine when ANRS/RIS (0.7%), IAS-USA (0.5%) or Stanford algorithms (5.0%) were used. V106I, which was detected in 3.8% of the patients, was the main mutation driving these differences. V106I detection was not associated with any of the clinical, demographic or virological characteristics of the patients. CONCLUSIONS: The prevalence of NRTI and PI TDR remains constant in Spain. Doravirine TDR is very infrequent by RIS/ANRS/IAS-USA algorithms, in contrast with results using the Stanford algorithm. Further genotype-phenotype studies are necessary to elucidate the role of V106I in doravirine resistance.

BACKGROUND: Screening methods for anal squamous intraepithelial lesions (SILs) are suboptimal. We aimed to determine the diagnostic performance of a composite endpoint comprising anal liquid-based cytology (aLBC) and high-risk human papillomavirus (HR-HPV) testing to predict histological high-grade SILs (hHSILs). METHODS: From the SeVIHanal cohort, human immunodeficiency virus (HIV)-infected men who have sex with men (MSM) who had an aLBC with concomitant HR-HPV testing were included. hHSILs were determined by high-resolution anoscopy (HRA)-guided biopsy. RESULTS: A total of 705 visits obtained from 426 patients were included. The prevalence of HR-HPV among aLBC results were 51.9% (133/215) normal, 87.9% (20/232) low-grade SILs (LSILs), and 90.9% (149/164) high-grade SILs; P (linear association) < .001. Low prevalence of hHSILs was only observed for the composite aLBC/HR-HPV testing endpoint "normal/noHR-HPV" (10%) and "LSIL/noHR-HPV" (4%). The prognostic values (95% confidence interval) for HR-HPV to predict hHSILs in normal cytology were positive predictive value (PPV), 29.3% (25.6%-33.3%); negative predictive value (NPV), 90.2% (82.8%-94.7%); sensitivity, 83% (69.2%-92.4%); and specificity, 44.1% (36.4%-51.9%). Corresponding figures for cytologic LSILs were PPV, 39.2% (37.4%-41.1%); NPV, 96.4% (78.9%-99.5%); sensitivity, 98.8% (93.3%-99.9%); and specificity, 17.9% (12.1%-24.9%). A positive interaction and a synergistic effect for the composite endpoint were observed (relative excess risk = 1.50, attributable proportion of histological results to interaction = 0.17, synergy index = 1.24). CONCLUSIONS: HRA should not be indicated in the setting of LSILs/noHR-HPV following aLBC-based screening. In contrast, HIV-infected MSM with normal aLBC/HR-HPV infection should be considered for HRA.

BACKGROUND: Integrase strand-transfer inhibitors (INSTIs) constitute at present one of the pillars of first-line ART. OBJECTIVES: To study the prevalence of and the trend in transmitted drug resistance (TDR) to INSTIs in ART-naive patients in Spain. METHODS: During the period 2012-17, 1109 patients from CoRIS were analysed. The Stanford algorithm v8.7 was used to evaluate TDR and transmission of clinically relevant resistance. To describe individual mutations/polymorphisms, the most recent IAS list (for INSTIs) and the 2009 WHO list update (for the backbone NRTIs used in combination with INSTIs in first-line treatment) were used. RESULTS: Clinically relevant resistance to the INSTI class was 0.2%: T66I, 0.1%, resistance to elvitegravir and intermediate resistance to raltegravir; and G163K, 0.1%, intermediate resistance to raltegravir and elvitegravir. No clinical resistance to dolutegravir or bictegravir was observed. The prevalence of INSTI TDR following the IAS-USA INSTI mutation list was 2.6%, with no trend towards changes in the prevalence throughout the study period. The overall prevalence of NRTI WHO mutations was 4.3%, whereas clinically relevant resistance to tenofovir, abacavir and emtricitabine/lamivudine was 1.7%, 1.9% and 0.7%, respectively. CONCLUSIONS: Given the low prevalence of clinically relevant resistance to INSTIs and first-line NRTIs in Spain, it is very unlikely that a newly diagnosed patient will present with clinical resistance to a first-line INSTI-based regimen. These patients may not benefit from INSTI and NRTI baseline resistance testing.

Background: There are contradictory data about the influence that hepatitis C virus (HCV) has on immune activation and inflammation in patients coinfected with human immunodeficiency virus (HIV) and HCV. Methods: HIV/HCV-coinfected patients receiving antiretroviral treatment who achieved a sustained virological response with interferon-free regimens were consecutively enrolled in a prospective study. The following factors were assessed before, immediately after the end of, and 1 month after the end of therapy: expression of HLA-DR/CD38, PD-1, and CD57 on CD4+ and CD8+ T-cells; measurement of the total HIV DNA load in peripheral blood mononuclear cells; and determination of plasma levels of soluble CD14 (sCD14), lipopolysaccharide (LPS), 16S ribosomal DNA (rDNA), interleukin 6 (IL-6), D-dimers, and high-sensitivity C-reactive protein (hsCRP). Results: Ninety-seven patients were consecutively included. At the end of therapy and 1 month later, there were significant reductions in the expression of HLA-DR and CD38 in CD4+ and CD8+ T cells, as well as levels of proviral HIV DNA, sCD14, LPS, 16S rDNA, and D-dimer (P < .001). By contrast, the expression of PD-1 and CD57 in CD4+ and CD8+ T cells and levels of IL-6 and hsCRP did not change. The improvement in levels of immune activation markers, proviral HIV DNA, and microbial translocation markers did not translate into an increased CD4+ T-cell count or increased ratio of the CD4+ T-cell count to the CD8+ T-cell count. Conclusions: HCV eradication in HIV/HCV-coinfected patients results in significant decreases in levels of immune activation markers, proviral HIV DNA load, microbial translocation markers, and D-dimers. These findings support the use of HCV treatment for all HIV/HCV-coinfected patients, even those with low-grade fibrosis.

BACKGROUND: There are several regimens for starting antiretroviral treatment, but it remains unknown whether either of them is more advantageous regarding the time course and magnitude of human immunodeficiency virus (HIV) RNA decay in semen. OBJECTIVE: To evaluate the differential effect of different antiretroviral drug families on viral kinetics in seminal plasma (SP) of treatment-naive HIV-infected patients. METHODS: Phase II, randomized, open-label study in which participants were randomized 1:1:1 to receive tenofovir-disoproxil fumarate (DF) plus emtricitabine, and either cobicistat-boosted elvitegravir (EVGcobi), rilpivirine (RPV), or ritonavir-boosted darunavir (DRVrtv). The primary endpoint was the proportion of participants with undetectable HIV-RNA in SP at week 12. HIV type 1 (HIV-1) RNA was measured in paired SP and blood plasma (BP) at baseline and after 1, 2, 4, 6, 8, 12, 18, and 24 weeks. Elvitegravir (EVG), RPV, and darunavir (DRV) concentrations were quantified by the liquid chromatography-tandem mass spectrometry method. RESULTS: In SP, the HIV-RNA decay rate with RPV was as fast as with EVGcobi; by week 12, all participants in the RPV and the EVGcobi groups reached an undetectable viral load but only 58.3% in the DRVrtv arm (P = .003). The highest SP/BP drug concentration ratio was for EVG (0.43), followed-up by RPV (0.19), and DRV (0.10). For both EVG and RPV, the SP concentrations exceeded >2-fold the protein binding-adjusted EC90 for wild-type HIV-1; for DRV, only 33.7% of the SP showed concentrations above the protein binding-adjusted EC90. CONCLUSIONS: In SP, both RPV and EVGcobi, associated to tenofovir-DF and emtricitabine, behave similarly and achieve an undetectable viral load much faster than DRVrtv.

Objectives: To evaluate if there are significant drug-drug interactions between cobicistat-boosted elvitegravir and 800 mg darunavir once daily taken simultaneously, as has been suggested previously. Methods: The study population consisted of three groups of unselected volunteers taking a regimen of elvitegravir, cobicistat, emtricitabine and tenofovir disoproxil fumarate (150, 150, 200 and 300 mg, respectively) co-formulated in a single tablet plus 800 mg darunavir (group A); only co-formulated elvitegravir, cobicistat, emtricitabine and tenofovir disoproxil fumarate (group B); and cobicistat-boosted darunavir (800 mg darunavir + 150 mg cobicistat) plus two nucleos(t)ide analogues (group C). Elvitegravir, cobicistat and darunavir concentrations at the end of the dosing interval ( C 24 ) were quantified using a validated LC with tandem MS method. Results: A total of 170 samples were obtained from 24, 32 and 32 patients in groups A, B and C, respectively. In group A, the elvitegravir C 24 were similar to those in group B (233.67 versus 250.39 ng/mL) ( P = 0.406) and the darunavir C 24 were similar to those in group C (1293.54 versus 1319.34 ng/mL) ( P = 0.908). The cobicistat C 24 were comparable in groups A and B (20.2 versus 20.9 ng/mL) and slightly higher in group C (27.7 ng/mL) ( P = 0.059). Conclusions: The results provide evidence of similar elvitegravir and darunavir C 24 concentrations when these drugs are co-administered as co-formulated elvitegravir, cobicistat, emtricitabine and tenofovir disoproxil fumarate plus 800 mg darunavir or dosed separately.

A higher incidence of anemia has been observed during the treatment of hepatitis C virus genotype 1 (HCV-1) infection with pegylated alpha interferon (pegIFN-α), ribavirin, and telaprevir. We assessed the impacts that concomitant administration of telaprevir and changes in the glomerular filtration rate have on ribavirin plasma levels. The minimum concentrations of ribavirin in plasma (ribavirin Cmin) determined during triple therapy including telaprevir were compared with those observed after telaprevir withdrawal and those observed in the same subjects and in a large cohort during a previous course of pegIFN-α plus ribavirin. Intensive pharmacokinetic sampling for ribavirin was performed at steady state during the triple-therapy phase. Ribavirin levels were measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Twenty-seven HCV-1/HIV-coinfected patients were enrolled. The median ribavirin Cmin for triple therapy (4.08 µg/ml; range, 2.14 to 5.56 µg/ml) was higher than that observed after telaprevir withdrawal (1.96 µg/ml; range, 0.41 to 3.45 µg/ml) (P < 0.001) and that observed for 125 HCV-1/HIV-coinfected patients treated only with pegIFN-α plus ribavirin (1.65 µg/ml; range, 0.41 to 5.56 µg/ml) (P < 0.001). The estimated glomerular filtration rate (eGFR) decreased >20% from the baseline value in 11 of 27 patients and became normal after telaprevir removal in almost all cases. There was a negative correlation between eGFR and ribavirin clearance (r(2) = 0.257; P = 0.064) but not the ribavirin area under the concentration-time curve from 0 to 12 h (AUC0-12) (r(2) = 0.001; P = 0.455). Thus, there is a significant pharmacokinetic interaction between telaprevir and ribavirin that results in very high ribavirin levels, which explains the excess of toxicity observed with this drug combination. A blockade of the proximal tubular transporters might be implicated in both the increase in plasma creatinine and the high ribavirin levels.

BACKGROUND: Detrimental bidirectional pharmacokinetic interactions have been observed when telaprevir (TVR) and ritonavir (RTV)-boosted human immunodeficiency virus (HIV) protease inhibitors are coadministered in healthy volunteers. Our aim was to evaluate the role of RTV in the bidirectional TVR and atazanavir (ATV) interactions. METHOD: An open-label, sequential study was carried out in hepatitis C virus (HCV)/HIV-coinfected patients on a RTV-boosted ATV-based (ATVr) antiretroviral regimen (300/100 mg every 24 hours) and triple therapy for chronic C hepatitis genotype 1 (TVR, 1125 mg every 12 hours, pegylated interferon-alpha and ribavirin). Pharmacokinetic profiles were acquired before and after switching from ATVr to unboosted ATV (200 mg every 12 hours). The plasma levels of both drugs were determined by liquid chromatography coupled with mass spectrometry. Pharmacokinetic parameters were calculated by noncompartmental analysis and compared by geometric mean ratios and their 90% confidence intervals. RESULTS: Fourteen white HCV/HIV-coinfected males were enrolled in this study. After RTV was withdrawn, the TVR AUC(0-12) (area under the concentration-time curve), maximum concentration (C(max)), and minimum concentration (C(min)) values increased by 19% (7%-30%), 12% (0.9%-29%), and 18% (2%-34%), respectively, without any changes in the TVR terminal half-life. The ATV AUC(0-12), C(max), and C(min) values were 39% (13%-66%), 19% (8%-59%), and 48% (1%-96%) higher, respectively, with a significantly shorter terminal half-life (22.6 hours vs 10.4 hours). CONCLUSIONS: RTV is responsible for the adverse interactions that occur when TVR and ATVr are administered together, possibly by influencing either the absorption phase or first-pass metabolism of TVR. The boost effect of TVR on ATV exposure is higher than on RTV, despite its shorter terminal half-life. The coadministration of TVR and unboosted ATV results in increased exposure of both drugs compared with their coadministration with RTV. CLINICAL TRIALS REGISTRATION: ClinicalTrials.gov: NCT01818856.

Real-life data on doravirine (DOR) in different drug combinations are limited. We evaluated the effectiveness of DOR plus two nucleos(t)ide reverse transcriptase inhibitors (NRTI), mainly abacavir/lamivudine, and dual therapies in people with HIV (PWH), mostly virologically suppressed. Ambispective observational study that enrolled adults PWH who initiated a DOR-based regimen from September 2020 to February 2022 at a referral center in Spain. Participants were grouped as follows: A, received DOR plus two NRTI; B, dual therapy (DT) with DOR plus dolutegravir (DTG) or darunavir/cobicistat (DRVc); C, DOR plus ≥two antiretroviral drugs. The primary endpoints were treatment effectiveness at week 48 by intention-to-treat (ITT) and per-protocol analysis (OT). A cohort of 187 participants, 91% virologically suppressed, were analyzed after a median follow-up of 112 weeks (80-136). Group A received DOR plus abacavir/lamivudine (ABV/3TC) (n = 109) or tenofovir/emtricitabine (TFV/3TC) (n = 45). At week 48, the effectiveness of DOR plus ABV/3TC by ITT was 90.8% (CI95, 88.0-93.6), better than with TFV/FTC [73.3% (66.7-79.9); P = 0.003]. Only one virologic failure was observed. Mild adverse effects were the cause of treatment discontinuation in 7.8%, followed by switching to a single-tablet regimen. In group B, the effectiveness by ITT was 92.9% (CI95, 88.0-97.8) at week 48. No adverse effects or virologic failure were registered in this group. DOR plus two NRTI or DT have long-term effectiveness and safety as a switching option for PWH, mostly virologically suppressed. The DOR plus ABV/3TC combination has shown even better effectiveness than TFV/FTC.IMPORTANCEDOR-based regimens have shown long-term effectiveness and safety in PWH, mostly virologically suppressed. The combination of DOR plus ABV/3TC has shown even better safety and effectiveness than TFV/FTC. DOR plus two NRTI offers cost benefits compared to other regimens.

Objective: To compare the long-term effects on immune parameters, inflammation, and HIV-1 reservoir after switching to a two-drug (2DR) versus maintaining an integrase inhibitor (InSTI)-based three-drug regimen (3DR). Methods: Cross-sectional study in which HIV-1 treatment-naïve people started and maintained an InSTI-based 3DR or, at different times, switched to 2DR (dolutegravir or darunavir/cobicistat + lamivudine). CD4+ and CD8+ T-cell activation and exhaustion, plasma concentrations of hs-CRP, D-dimer, P-selectin, IL-1ß, IL-6, TNF-α, IFN-γ, IP-10, sTNFR-I/II, MIP-1α/ß, I-FABP, LBP, sCD14, sCD163, MCP-1, and cellular-associated HIV-1-DNA and -RNA were quantified by flow cytometry, different immunoassays, and droplet digital PCR, respectively. The U de Mann-Whitney test evaluated differences between 3DR and 2DR. Immune recovery was evaluated using a general linear model for repeated measures adjusted for different co-variables. Results: Fifty participants per group were included. The median time on 3DR was 82 months for the 3DR group and 30 months for the 2DR group, after which it switched to 2DR for a median of 57 months. We did not find differences between both groups in any of the parameters analyzed. Specifically, some values in 3DR and 2DR were hs-CRP, 0.92 mg/L (0.45-2.23) vs. 1.23 (0.61-2.38); D-dimer, 190.0 µg/L (150.0-370.0) vs. 190.0 (150.0-397.5); IL-6, 2.8 pg/mL (1.3-5.3) vs. 3.2 (2.1-4.7); sCD14, 4.5 ng/mL (3.3-6.2) vs. 5.0 (3.6-6.1), respectively, all p ≥ 0.399. Conclusion: In the long term, switching to 2DR does not negatively affect immunologic parameters, inflammatory markers, or HIV-1 reservoir. Clinical trial registration: identifier NCT04076423.

Objective: The incidence of type 2 diabetes mellitus (T2DM) has risen dramatically. Among people living with HIV (PLHIV), chronic disease (now >15 cases/1000 in the general population worldwide) and long-term exposure to antiretroviral therapy (ART) can alter metabolic processes early, favoring insulin resistance and T2DM. We retrospectively studied the incidence of T2DM and associated factors in the Cohort of the Spanish AIDS Research Network, a prospective cohort of PLHIV enrolled at diagnosis and before initiation of ART. Methods: PLHIV were aged >18 years and ART naive at inclusion. The incidence of new diagnoses of T2DM after initiation of ART (per 1000 person-years) was calculated. Predictors of a diagnosis of T2DM were identified by a Cox proportional hazards model adjusted for statistically significant and clinically relevant variables. Results: Cumulative incidence was 5.9 (95% CI, 5.1-6.7) per 1000 person-years, increasing significantly in persons aged >50 years to 14.4 (95% CI, 10.4-19.3). Median time to diagnosis of T2DM was 27 months. Only age and higher education were significant. Interestingly, higher education was associated with a 33% reduction in the incidence of T2DM. Having received tenofovir disoproxil fumarate + (lamivudine or emtricitabine) + rilpivirine was almost significant as a protective factor (hazard ratio, 0.49; 95% CI, .24-1.01; P = .05). Conclusions: The incidence of T2DM in PLHIV in Spain was high, especially in persons aged >50 years. Age was the factor most closely associated with onset, and educational level was the factor most associated with reduced risk. We highlight the lack of association between HIV-related factors and T2DM and show that, within nonnucleoside reverse transcriptase inhibitors, rilpivirine could prove more benign for metabolic comorbidities.
RESUMO
Rat hepatitis E virus (ratHEV; species Rocahepevirus ratti) is considered a newly emerging cause of acute hepatitis of zoonotic origin. ratHEV infection of people living with HIV (PLWH) might portend a worse, as with hepatitis E virus (HEV; species Paslahepevirus balayani), and consequently this group may constitute a high-risk population. We aimed to evaluate the prevalence of ratHEV by measuring viral RNA and specific IgG antibodies in a large Spanish cohort of PLWH. Multicentre study conducted in Spain evaluating PLWHIV included in the Spanish AIDS Research Network (CoRIS). Patients were evaluated for ratHEV infection using PCR at baseline and anti-ratHEV IgG by dot blot analysis to evaluate exposure to ratHEV strains. Patients with detectable ratHEV RNA were followed-up to evaluate persistence of viremia and IgG seroconversion. Eight-hundred and forty-two individuals were tested. A total of 9 individuals showed specific IgG antibodies against ratHEV, supposing a prevalence of 1.1 (95% CI; 0.5%-2.1%). Of these, only one was reactive to HEV IgG antibodies by ELISA. One sample was positive for ratHEV RNA (prevalence of infection: 0.1%; 95% CI: 0.08%-0.7%). The case was a man who had sex with men exhibiting a slightly increased alanine transaminase level (49 IU/L) as only biochemical alteration. In the follow-up, the patients showed undetectable ratHEV RNA and seroconversion to specific ratHEV IgG antibodies. Our study shows that ratHEV is geographical broadly distributed in Spain, representing a potential zoonotic threat.

BACKGROUNDWe evaluated the safety and viral rebound, after analytical treatment interruption (ATI), of vedolizumab and ART in recent HIV-1 infection. We used this model to analyze the effect of α4ß7 on the HIV-1 reservoir size.METHODSParticipants started ART with monthly vedolizumab infusions, and ATI was performed at week 24. Biopsies were obtained from ileum and cecum at baseline and week 24. Vedolizumab levels, HIV-1 reservoir, flow cytometry, and cell-sorting and antibody competition experiments were assayed.RESULTSVedolizumab was safe and well tolerated. No participant achieved undetectable viremia off ART 24 weeks after ATI. Only a modest effect on the time to achieve more than 1,000 HIV-1 RNA copies/mL and the proportion of participants off ART was observed, being higher in the vedolizumab group compared with historical controls. Just before ATI, α4ß7 expression was associated with HIV-1 DNA and RNA in peripheral blood and with PD1 and TIGIT levels. Importantly, a complete blocking of α4ß7 was observed on peripheral CD4+ T cells but not in gut (ileum and cecum), where α4ß7 blockade and vedolizumab levels were inversely associated with HIV-1 DNA.CONCLUSIONOur findings support α4ß7 as an important determinant in HIV-1 reservoir size, suggesting the complete α4ß7 blockade in tissue as a promising tool for HIV-cure combination strategies.TRIAL REGISTRATIONClinicalTrials.gov NCT03577782.FUNDINGThis work was supported by the Instituto de Salud Carlos III (Fondo Europeo de Desarrollo Regional, "a way to make Europe," research contracts FI17/00186 and FI19/00083 and research projects PI18/01532, PI19/01127, PI22/01796), Conserjería de Economía, Conocimiento, Empresas y Universidad, Junta de Andalucía (research projects P20/00906), the Red Temática de Investigación Cooperativa en SIDA (RD16/0025/0020), and the Spanish National Research Council.

BACKGROUNDPersistent controllers (PCs) maintain antiretroviral-free HIV-1 control indefinitely over time, while transient controllers (TCs) eventually lose virological control. It is essential to characterize the quality of the HIV reservoir in terms of these phenotypes in order to identify the factors that lead to HIV progression and to open new avenues toward an HIV cure.METHODSThe characterization of HIV-1 reservoir from peripheral blood mononuclear cells was performed using next-generation sequencing techniques, such as full-length individual and matched integration site proviral sequencing (FLIP-Seq; MIP-Seq).RESULTSPCs and TCs, before losing virological control, presented significantly lower total, intact, and defective proviruses compared with those of participants on antiretroviral therapy (ART). No differences were found in total and defective proviruses between PCs and TCs. However, intact provirus levels were lower in PCs compared with TCs; indeed the intact/defective HIV-DNA ratio was significantly higher in TCs. Clonally expanded intact proviruses were found only in PCs and located in centromeric satellite DNA or zinc-finger genes, both associated with heterochromatin features. In contrast, sampled intact proviruses were located in permissive genic euchromatic positions in TCs.CONCLUSIONSThese results suggest the need for, and can give guidance to, the design of future research to identify a distinct proviral landscape that may be associated with the persistent control of HIV-1 without ART.FUNDINGInstituto de Salud Carlos III (FI17/00186, FI19/00083, MV20/00057, PI18/01532, PI19/01127 and PI22/01796), Gilead Fellowships (GLD22/00147).

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is one of the most important liver comorbidities in people living with HIV (PLWH). Factors that could lead to a higher prevalence of NAFLD or ease the onset of fibrosis are unclear. METHODS: Cohort study of the Spanish HIV Research Network, which comprehends 46 hospitals and more than 15,000 PLWH. Primary objectives were to assess NAFLD prevalence and liver fibrosis according to hepatic steatosis index (HSI) and NAFLD fibrosis score, respectively. Factors associated with both were analysed. RESULTS: A total of 4798 PLWH were included of whom 1461 (30.5%) showed an HSI>36; these patients had higher risk for significant fibrosis (OR 1.91; 95%CI 1.11-3.28). Factors associated with NAFLD were body mass index (OR 2.05; 95%CI 1.94-2.16) and diabetes (OR 4.68; 95%CI 2.17-10.08), while exposure to integrase strand transfer inhibitors showed a lower risk (OR 0.78; 95%CI 0.62-0.97). In patients with HSI>36, being female (OR 7.33; 95%CI 1.34-40), age (OR 1.22; 95%CI 1.11-1.34), body mass index (OR 1.35; 95%CI 1.18-1.54) and exposure to thymidine analogues (OR 75.4, 95%CI 6.9-823.5) were associated with a higher risk of significant fibrosis. However, exposure to non-nucleoside reverse transcriptase inhibitors (OR 0.12, 95%CI 0.02-0.89) and time of exposure to protease inhibitors (OR 0.97, 95%CI 0.95-1) showed a lower risk. CONCLUSION: NAFLD prevalence was high in our cohort. Patients exposed to INSTI showed a lower risk of NAFLD. In patients with hepatic steatosis, exposure to thymidine analogues had 75-fold more risk of significant fibrosis while exposure to NNRTIs reduced this risk.
