RESUMO

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

INTRODUCTION: Dolutegravir + rilpivirine (DTG + RPV) is an effective antiretroviral therapy regimen approved in clinical guidelines as a switch therapy for virologically suppressed people with HIV. Our study aimed to compare the effectiveness and tolerability of DTG + RPV in women and men in real-world clinical practice. METHODS: This was a retrospective analysis of treatment-experienced people with HIV from a large HIV unit who switched to DTG + RPV. We analysed treatment effectiveness, rates of adverse events and discontinuation, and metabolic changes after 48 weeks of treatment. HIV-RNA levels <50 copies/mL were analysed at 48 weeks using both intention-to treat analysis (where missing data were interpreted as failures) and per-protocol analysis (excluding those with missing data or changes due to reasons other than virological failure). Outcomes were compared between women and men based on sex at birth. RESULTS: A total of 307 patients were selected (71 women and 236 men). No transgender people were included. At baseline, women had lived with HIV infection and received antiretroviral therapy for longer than men (23.2 vs 17.4 years and 18.9 vs 14.2 years, respectively). In the intention-to-treat analysis, 74.6% (95% confidence interval [CI] 63.4-83.3%) of women and 83.5% (95% CI 78.2-87.7) of men had HIV-RNA <50 copies/mL. In the per-protocol analysis, 96.4% (95% CI 87.7-99) of women and 99% (95% CI 98.9-99.7) of men had HIV-RNA levels <50 copies/mL. Two women and two men had HIV-RNA >50 copies/mL at 48 weeks. Discontinuation due to adverse events was more frequent in women than in men: 12.7% vs 7.2% (p < 0.02). Neuropsychiatric and gastrointestinal events were the most frequently reported. A median (interquartile range) weight gain of 1.9 kg (0-4.2) in women and 1.2 kg (-1-3.1) in men was reported (median of differences between baseline visit and week 48); the remaining changes in metabolic parameters were neutral. CONCLUSIONS: DTG + RPV exhibited good and similar virological effectiveness in women and men in real-world settings. However, poorer tolerability and more treatment interruptions were observed in women.

RESUMO

INTRODUCTION: Due to hepatitis B virus (HBV) treatment and vaccination during the last decades in Spain, epidemiological and prognosis of chronic hepatitis B (CHB) may have changed. METHODS: Retrospective review of CHB-HIV coinfected patients in a single reference center in Madrid until year 2019. We compared incidence, epidemiological and clinical characteristics according diagnosis period (before 2000, 2000-2004, 2005-2009, 2010-2014, 2015-2019). A retrospective longitudinal study was done to assess mortality, related risk factors and hepatic decompensation. RESULTS: Out of 5452 PLHIV, 160 had CHB (prevalence 2.92%; 95%CI 2.5-3.4), 85.6% were men, median age 32.1 (27-37.2). Incidence rate did not change over the years (2.4/100 patients-year). PLHIV with CHB diagnosed before year 2000 (n = 87) compared with those diagnosed between 2015 and 2019 (n = 11) were more often native-Spanish (90.8% vs. 18.2%), had infected using intravenous drugs (55.2% vs. 0), were coinfected with hepatitis C (40% vs. 9.1%) or hepatitis delta virus (30.4% vs. 0) and had more severe liver disease (cirrhosis 24.1% vs. 0). After a median follow-up of 20.4 years, 23 patients died (7.1/1000 patients-year) and 19 had liver decompensation (4.9/1000 patients-year). All deaths and liver decompensation occurred in patients diagnosed before year 2010. Mortality was associated with higher liver fibrosis in Fibroscan® (HR 1.06, 95% CI 1.03-1.09). CONCLUSION: The epidemiology of CHB in PLHIV in our cohort is changing with less native Spanish, more sexually transmitted cases and less coinfection with other hepatotropic virus. Patients diagnosed before 2010 have worst prognosis related to higher grades of liver fibrosis.

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.

RESUMO

Metabolic-dysfunction-associated fatty liver disease (MAFLD) is a comorbidity that generally increases in people living with HIV (PLWH). This condition is usually accompanied by persistent inflammation and premature immune system aging. In this prospective cohort study, we describe a straightforward methodology for quantifying biomarkers of aging, such as DNA methylation and telomere length, in PLWH and in the context of another relevant condition, such as MAFLD. Fifty-seven samples in total, thirty-eight from PLWH and nineteen from non-PLWH participants with or without MAFLD, were obtained and subjected to DNA extraction from peripheral blood mononuclear cells (PBMCs). Global DNA methylation and telomere length quantification were performed using an adapted enzyme-linked immunosorbent assay (ELISA) and qPCR, respectively. The quantification results were analysed and corrected by clinically relevant variables in this context, such as age, sex, and metabolic syndrome. Our results show an increased association of these biomarkers in PLWH regardless of their MAFLD status. Thus, we propose including the quantification of these age-related factors in studies of comorbidities. This will allow a better understanding of the effect of comorbidities of HIV infection and MAFLD and prevent their effects in these populations in the future.

RESUMO

BACKGROUND: To understand the effects of frailty, geriatric syndromes, and comorbidity on quality of life and mortality in older adults with HIV (OAWH). METHODS: Cross-sectional study of the FUNCFRAIL multicenter cohort. The setting was outpatient HIV-Clinic. OAWH, 50 year or over were included. We recorded sociodemographic data, HIV infection-related data, comorbidity, frailty, geriatric syndromes (depression, cognitive impairment, falls and malnutrition), quality of life (QOL) and the estimated risk of all-cause 5-year mortality by VACS Index. Association of frailty with geriatric syndromes and comorbidity was evaluated using the Cochran-Mantel-Haenszel test. RESULTS: Seven hundred ninety six patients were included. 24.7% were women, mean age was 58.2 (6.3). 14.7% were 65 or over. 517 (65%) patients had ≥3 comorbidities, ≥ 1 geriatric syndrome and/or frailty. There were significant differences in the estimated risk of mortality [(frailty 10.8%) vs. (≥ 3 comorbidities 8.2%) vs. (≥ 1 geriatric syndrome 8.2%) vs. (nothing 6.2%); p = 0.01] and in the prevalence of fair or poor QOL [(frailty 71.7%) vs. (≥ 3 comorbidities 52%) vs. (≥ 1 geriatric syndrome 58.4%) vs. (nothing 51%); p = 0.01]. Cognitive impairment was significantly associated to mortality (8.7% vs. 6.2%; p = 0.02) and depression to poor QOL [76.5% vs. 50%; p = 0.01]. CONCLUSIONS: Frailty, geriatric syndromes, and comorbidity had negative effects on mortality and QOL, but frailty had the greatest negative effect out of the three factors. Our results should be a wake-up call to standardize the screening for frailty and geriatric syndromes in OAWH in the clinical practice. TRIAL REGISTRATION: NCT03558438.

RESUMO

INTRODUCTION: The use of tenofovir alafenamide (TAF) has been associated with increased cholesterol and body weight. Real-life data on the metabolic effects of switching from a TAF-based triple regimen to a dolutegravir (DTG)-based two-drug regimen (2-DR) are scarce. METHODS: A retrospective cohort study of patients who have switched from a triple TAF-based regimen to a 2-DR [DTG-lamivudine (DTG-3TC) or DTG- rilpivirine (DTG-RPV]) with at least 6 months of follow-up. The primary endpoint was the absolute change in lipid fractions at 6 months. Secondary outcomes were percentage changes in lipid fraction, effectiveness and safety at 6 and 12 months [intention to treat (ITT), missing = failures]. RESULTS: A total of 118 patients (87 on DTG-3TC, 31 on DTG-RPV) were included. Median age was 51 years (interquartile range: 43-59), 86% were male, CD4 T-cell count was 692 cells/µL, and 98% viral load (VL) < 50 copies/mL. At 6 months there was a decrease in total and low-density lipoprotein cholesterol of 10.7 mg/dL [95% confidence interval (CI): 2.2-19.1; p ≤ 0.001] and 8.3 mg/dL (95% CI: 0.74-15.9; p = 0.026), respectively. There was a reduction in cardiovascular risk from 4.5% at baseline to 4% at 12 months (p = 0.040). Virological effectiveness as determined by ITT analysis was 85.6% at 6 months and 66.1% at 12 months. Seven patients (5.9%) withdrew from the 2-DR and there was no virological failure. CONCLUSIONS: In real life, switching from a triple regimen with TAF to DTG-3TC or DTG-RPV dual therapy improves the lipid profile and is an effective and well-tolerated strategy.

RESUMO

Introduction: Metabolic dysfunction-associated steatotic liver disease (MASLD), has emerged as an increasingly recognized problem among people living with HIV (PLWH). The gut-liver axis is considered to be strongly implicated in the pathogenesis of MASLD. We aimed to characterize the gut microbiota composition in PLWH and MASLD and compare it with that of two control groups: PLWH without MASLD and individuals with MASLD without HIV infection. Methods: We collected clinical data and stool samples from participants. Bacterial 16S rRNA genes were amplified, sequenced, and clustered into operational taxonomic unit. Alpha diversity was studied by Shannon and Simpson indexes. To study how different the gut microbiota composition is between the different groups, beta diversity estimation was evaluated by principal coordinate analysis (PCoA) using Bray-Curtis dissimilarity. To further analyze differences in microbiome composition we performed a linear discriminant analysis (LDA) effect size (LEfSe). Results: We included 30 HIV+MASLD+, 30 HIV+MASLD- and 20 HIV-MASLD+ participants. Major butyrate producers, including Faecalibacterium, Ruminococcus, and Lachnospira dominated the microbiota in all three groups. Shannon's and Simpson's diversity metrics were higher among MASLD+ individuals (Kruskal-Wallis p = 0.047). Beta diversity analysis showed distinct clustering in MASLD-, with MASLD+ participants overlapping regardless of HIV status (ADONIS significance <0.001). MASLD was associated with increased homogeneity across individuals, in contrast to that observed in the HIV+NAFDL- group, in which the dispersion was higher (Permanova test, p value <0.001; ANOSIM, p value <0.001). MASLD but not HIV determined a different microbiota structure (HIV+MASLD- vs. HIV+MASLD+, q-value = 0.002; HIV-MASLD+ vs. HIV+MASLD+, q-value = 0.930; and HIV-MASLD+ vs. HIV+MASLD-, q-value < 0.001). The most abundant genera in MASLD- were Prevotella, Bacteroides, Dialister, Acidaminococcos, Alloprevotella, and Catenibacterium. In contrast, the most enriched genera in MASLD+ were Ruminococcus, Streptococcus, Holdemanella, Blautia, and Lactobacillus. Conclusions: We found a microbiome signature linked to MASLD, which had a greater influence on the overall structure of the gut microbiota than HIV status alone.

RESUMO

Paleotemperature proxy data form the cornerstone of paleoclimate research and are integral to understanding the evolution of the Earth system across the Phanerozoic Eon. Here, we present PhanSST, a database containing over 150,000 data points from five proxy systems that can be used to estimate past sea surface temperature. The geochemical data have a near-global spatial distribution and temporally span most of the Phanerozoic. Each proxy value is associated with consistent and queryable metadata fields, including information about the location, age, and taxonomy of the organism from which the data derive. To promote transparency and reproducibility, we include all available published data, regardless of interpreted preservation state or vital effects. However, we also provide expert-assigned diagenetic assessments, ecological and environmental flags, and other proxy-specific fields, which facilitate informed and responsible reuse of the database. The data are quality control checked and the foraminiferal taxonomy has been updated. PhanSST will serve as a valuable resource to the paleoclimate community and has myriad applications, including evolutionary, geochemical, diagenetic, and proxy calibration studies.

RESUMO

INTRODUCTION: Few clinical trials and cohort studies have evaluated the efficacy of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in people with HIV (PWH) with preexisting M184V/I or other nucleos(t)ide reverse transcriptase inhibitor (NRTI) resistance-associated mutations (RAMs). Real-world data are also scarce. METHODS: Retrospective review of treatment-experienced patients who started B/F/TAF in a cohort of PWH. HIV-RNA less than 50 copies/ml was analyzed at 48 weeks in an intention-to-treat (ITT) analysis (missing=failure) and per protocol analysis (patients with missing data or changes for reasons other than virological failure were excluded). Results were compared in patients with and without previous NRTI-RAMs. RESULTS: Five hundred and six PWH were included (16.2% women). Median age and time with HIV infection were 52.3 and 18.9 years, respectively. At baseline, viral load was less than 50 copies/ml in 440 patients (86.6%). Overall, 69 (13.6%) participants had documented preexisting NRTI-RAMs: 57 (11.2%) M184V/I and 30 (5.9%) tenofovir RAMs. In the ITT analysis, 83% (420/506) had HIV-RNA less than 50 copies/ml [82.2% (359/437) and 88.4% (61/69) in persons without and with NRTI-RAMs, respectively ( P  = 0.2)]. In the per protocol analysis 94.2% (420/445) had HIV-RNA less than 50 copies/ml [94.4% (359/380) vs. 93.8% (61/65); P  = 0.2]. A total of 61 participants were excluded from the per protocol analysis (23 missing data, 19 discontinued B/F/TAF because of toxicity, 13 for other reasons, and 6 died). CONCLUSION: Switching to B/F/TAF is well tolerated and effective in the real-world setting, even in patients with preexisting NRTI RAMs, such as M184V and RAMs conferring resistance to tenofovir. These results confirm the robustness of this combination.

RESUMO

Despite its high prevalence, the mechanisms underlying non-alcoholic fatty liver disease (NAFLD) in people living with HIV (PLWH) are still unclear. In this prospective cohort study, we aim to evaluate differences in plasma fatty acid profiles between HIV-infected and HIV-uninfected participants with NAFLD. We included participants diagnosed with NAFLD, both HIV-infected and HIV-uninfected. Fatty acid methyl esters were measured from plasma samples. Ratios ([product]/[substrate]) were used to estimate desaturases and elongases activity. We used linear regression for adjusted analyses. We included 31 PLWH and 22 HIV-uninfected controls. We did not find differences in the sum of different types of FA or in FA with a greater presence of plasma. However, there were significant differences in the distribution of some FA, with higher concentrations of ALA, trans-palmitoleic, and behenic acids, and a lower concentration of lignoceric acid in PLWH. PLWH had lower C24:0/C22:0 and C16:0/C14:0 ratios, which estimates the activity of elongases ELOVL1 and ELOVL6. Both groups had similar fatty acid distribution, despite differences in traditional risk factors. PLWH had a lower proportion of specific ratios that estimate ELOVL1 and ELOVL6 activity, which had been previously described for other inflammatory conditions, such as psoriasis.

RESUMO

Evidence on the risk of hepatocellular carcinoma (HCC) in patients with stage 3 liver fibrosis (F3) and SVR is scarce and continues to generate uncertainty. Furthermore, the distinction between F3 and F4 disease is complex. Consequently, the latest international guidelines recommend using the same screening protocol for HCC after SVR in both F3 and F4 patients. However, the risk of HCC in these groups is possibly different and maintaining screening for HCC in this population indefinitely generates an excessive burden for the health system. This editorial aims to review the available evidence on this topic.

RESUMO

OBJECTIVE: The prevalence of subclinical liver abnormalities is high among people with HIV, but data regarding perinatally HIV-infected children and adolescents (PHIV) are scarce. Noninvasive image techniques offer an opportunity to address nonalcoholic fatty liver disease (NAFLD) in a population in which the scores validated for adults have not been tested. DESIGN: Prospective cross-sectional study including PHIV and uninfected controls. METHODS: Noninvasive imaging techniques for the diagnosis of NAFLD and/or fibrosis were performed, and four scores to predict NAFLD were evaluated. RESULTS: Seventy-six participants (59.2% women) with a median of 19 years old (interquartile range: 15.5-25.6) were included, 38 were PHIV and 38 were age and sex-matched controls. All HIV participants were on ART at the moment of inclusion, and 86.8% were virologically suppressed. A total of 11 PHIV and three controls were diagnosed with NAFLD (28.9% vs. 7.9%; P = 0.02) by noninvasive imaging techniques. The performance of scores based on clinical and analytical parameters was very poor. Although nonsignificant, overweight was more common among participants with NAFLD, who had a significantly higher BMI. Differences in HIV-related parameters between the groups were nonsignificant, except for the CD4+/CD8+ T-cells ratio, decreased among PHIV diagnosed with NAFLD (P = 0.04). CONCLUSIONS: The prevalence of NAFLD was high (28.9%) among PHIV, and only partially explained by overweight and metabolic syndrome defining factors. The scores based on clinical and analytical parameters did not accurately identify participants at risk. Therefore, liver ultrasound assessment should be considered for the screening of NAFLD among PHIV in routine clinical practice.

RESUMO

INTRODUCTION: Human immunodeficiency virus (HIV) infection and cirrhosis are associated with a senescent phenotype that decreases telomere length. We evaluated the impact of hepatitis C virus (HCV) elimination on telomere length in patients with advanced HCV-related cirrhosis after sustained virological response (SVR), with all-oral direct-acting antiviral agents (DAAs). METHODS: Prospective study of 60 HIV/HCV-coinfected and 30 HCV-monoinfected patients with advanced HCV cirrhosis (liver decompensation or liver stiffness measurement (LSM) ≥ 25 kPa, hepatic liver pressure gradient (HVPG) ≥ 10 mmHg, or Child-Pugh-Turcotte (CPT) ≥ 7). The relative telomere length (RTL) was quantified by real-time multiplex PCR (MMqPCR) on peripheral blood mononuclear cells at baseline and 48 weeks after HCV treatment. Generalized linear models (GLMs) adjusted for the most relevant clinical and epidemiological variables and mixed GLMs were used. RESULTS: In comparison with HCV-monoinfected patients, HIV/HCV-coinfected patients were younger (p < 0.001), had lower body mass index (BMI) (p = 0.002), and had been exposed less frequently to interferons (p = 0.011). In addition, they were more frequently men (p = 0.011), smokers (p = 0.005), prior intravenous drug users (IVDUs) (p < 0.001), and alcohol abusers (p = 0.005). RTL was significantly lower in HIV/HCV-coinfected patients than in HCV-monoinfected patients, both at baseline (p < 0.001), and at the end of follow-up (p = 0.032). A significant RTL increase over time was found only for HIV/HCV-coinfected patients (p < 0.001), especially in those patients with compensated cirrhosis (p < 0.001). CONCLUSION: HCV eradication with all-oral DAAs was associated with an increase in telomere length in HIV/HCV-coinfected patients with advanced cirrhosis, particularly in compensated patients. This finding suggests that HCV clearance may have implications in age-related conditions in this population group.

RESUMO

BACKGROUND AND AIMS: Limited data are available on the effectiveness and tolerability of direct-acting antivirals (DAAs) therapies in the real world for HCV-infected patients with comorbidities. This study aimed to describe the effectiveness of OBV/PTV/r ± DSV (3D/2D regimen) with or without ribavirin (RBV) in HCV or HCV/HIV co-infected patients with GT1/GT4 and CKD (IIIb-V stages), including those under hemodialysis and peritoneal dialysis in routine clinical practice in Spain in 2015. MATERIAL AND METHODS: Non-interventional, retrospective, multicenter data collection study in 31 Spanish sites. Socio-demographic, clinical variables, study treatment characteristics, effectiveness and tolerability data were collected from medical records. RESULTS: Data from 135 patients with a mean age (SD) of 58.3 (11.4) years were analyzed: 92.6% GT1 (81.6% GT1b and 17.6% GT1a) and 7.4% GT4, 14 (10.4%) HIV/HCV co-infected, 19.0% with fibrosis F3 and 28.1% F4 by FibroScan®, 52.6% were previously treated with pegIFN and RBV. 11.1%, 14.8% and 74.1% of patients had CKD stage IIIb, IV and V respectively. 68.9% of patients were on hemodialysis; 8.9% on peritoneal dialysis and 38.5% had history of renal transplant. A total of 125 (96.2%) of 135 patients were treated with 3D, 10 (7.4%) with 2D and 30.4% received RBV. The overall intention-to-treat (ITT) sustained virologic response at week 12 (SVR12) was 92.6% (125/135) and the overall modified-ITT (mITT) SVR12 was 99.2% (125/126). The SVR12 rates (ITT) per sub-groups were: HCV mono-infected (91.7%), HCV/HIV co-infected (100%), GT1 (92.0%), GT4 (100%), CKD stage IIIb (86.7%), stage IV (95%) and stage V (93%). Among the 10 non-SVR there was only 1 virologic failure (0.7%); 4 patients had missing data due lost to follow up (3.0%) and 5 patients discontinued 3D/2D regimen (3.7%): 4 due to severe adverse events (including 3 deaths) and 1 patient´s decision. CONCLUSIONS: These results have shown that 3D/2D regimens are effective and tolerable in patients with advanced CKD including those in dialysis with GT 1 or 4 chronic HCV mono-infection and HIV/HCV coinfection in a real-life cohort. The overall SVR12 rates were 92.6% (ITT) and 99.2% (mITT) without clinically relevant changes in eGFR until 12 weeks post-treatment. These results are consistent with those reported in clinical trials.

RESUMO

OBJECTIVE: Data of hepatitis C treatment with direct-acting antivirals (DAAs) in HIV infected patients are limited to a few number of antiretroviral therapies (ART). The aim of this study was to assess the effectiveness and safety of non-conventional ART as monotherapy or dual therapy (MDT) when combined with DAA. METHODS: Retrospective review of HIV/HCV-coinfected patients treated with DAAs during one year in 3 centers. Sustained virologic response 12 weeks after therapy (SVR) and maintenance of HIV viral suppression were compared between patients receiving triple ART (TT) or MDT. RESULTS: Overall 485 patients were included (359 receiving TT and 126 MDT). HCV SVR was 93.4% (95%CI, 90.8% to 95.3%) in the intention-to-treat analysis without differences between groups: 92.8% on TT vs 95.2% on MDT (p = 0.3). HCV virological failure was associated with lower CD4 + cell count at baseline (for every 100-cell/μl increment: OR, 0.8; 95%CI, 0.7-0.9; p = 0.01) and with liver stiffness (for every 10-unit increment: OR, 1.5; 95%CI 1.2-1.8; p < 0.01). HIV-RNA during HCV treatment or 12 weeks after was detectable in 23 patients on TT (6.6%) and 9 (7.2%) patients on MDT (p = 0.8). The median (IQR) change in CD4 + cell count was not significantly different between the groups: 15 (-55 to 115) in TT vs -12 (-68 to 133) cells/μl in MDT (p = 0.8). CONCLUSION: DAAs obtain high rates of SVR among HIV/HCV-coinfected patients independently of whether TT or non-conventional ART is used. Suppression of HIV was maintained in both groups


OBJETIVO: Los datos sobre el tratamiento de la hepatitis C con antivirales de acción directa (AAD) en los pacientes infectados por VIH se limitan a un escaso número de terapias antirretrovirales (TARV). El objetivo de este estudio fue valorar la efectividad y seguridad de las TARV no convencionales, como monoterapia y terapia dual (MDT), al combinarse con AAD. MÉTODOS: Revisión retrospectiva de pacientes co-infectados por VIH/VHC, tratados con AAD durante un año en 3 centros. Se comparó la respuesta virológica sostenida (RVS) a las 12 semanas de la terapia, y el mantenimiento de la supresión viral del VIH, entre los pacientes que recibieron triple TARV o MDT. RESULTADOS: Se incluyó a un total de 485 pacientes (359 que recibieron triple TARV y 126 que recibieron MDT). La RVS de VHC fue del 93,4% (IC 95%: 90,8-95,3%) en el análisis por intención de tratar, sin diferencias entre grupos: 92,8% en el grupo triple TARV vs. 95,2% en el grupo MDT (p = 0,3). El fracaso virológico de VHC se asoció a un menor recuento basal de células CD4+ (para cada incremento de 100células/μl: OR: 0,8; IC 95%: 0,7-0,9; p = 0,01) y a la rigidez hepática (para cada incremento de 10 unidades: OR: 1,5; IC 95%: 1,2-1,8; p < 0,01). El ARN-VIH durante el tratamiento de VHC, o transcurridas 12 semanas, fue detectable en 23 pacientes en el grupo triple TARV (6,6%) y 9 (7,2%) pacientes en el grupo MDT (p = 0,8). El cambio medio (RIC) en el recuento de células CD4 + no fue significativamente diferente entre ambos grupos: 15 (de -55-115) en el grupo triple TARV vs. -12 (de -68-133) células/μl en el grupo MDT (p = 0,8). CONCLUSIÓN: Los AAD obtienen tasas altas de RVS entre los pacientes co-infectados de VIH/VHC, independientemente de si se utiliza triple TARV o TARV no convencional. La supresión de VIH se mantuvo en ambos grupos

RESUMO

BACKGROUND: Current guidelines do not address the post-sustained virological response management of patients with baseline hepatitis C virus (HCV) cirrhosis and oesophageal varices taking betablockers as primary or secondary prophylaxis of variceal bleeding. We hypothesized that in some of these patients portal hypertension drops below the bleeding threshold after sustained virological response, making definitive discontinuation of the betablockers a safe option. AIM: To assess the evolution of portal hypertension, associated factors, non-invasive assessment, and risk of stopping betablockers in this population. METHODS: Inclusion criteria were age > 18 years, HCV cirrhosis (diagnosed by liver biopsy or transient elastography > 14 kPa), sustained virological response after direct-acting antivirals, and baseline oesophageal varices under stable, long-term treatment with betablockers as primary or secondary bleeding prophylaxis. Main exclusion criteria were prehepatic portal hypertension, isolated gastric varices, and concomitant liver disease. Blood tests, transient elastography, and upper gastrointestinal endoscopy were performed. Hepatic venous pressure gradient (HVPG) was measured five days after stopping betablockers. Betablockers could be stopped permanently if gradient was < 12 mmHg, at the discretion of the attending physician. RESULTS: Sample comprised 33 patients under treatment with propranolol or carvedilol: median age 64 years, men 54.5%, median Model for End-Stage Liver Disease (MELD) score 9, Child-Pugh score A 77%, median platelets 77.000 × 103/µL, median albumin 3.9 g/dL, median baseline transient elastography 24.8 kPa, 88% of patients received primary prophylaxis. Median time from end of antivirals to gradient was 67 wk. Venous pressure gradient was < 12 mmHg in 13 patients (39.4%). In univariate analysis the only associated factor was a MELD score decrease from baseline. On endoscopy, variceal size regressed in 19/27 patients (70%), although gradient was ≥ 12 mmHg in 12/19 patients. The elastography area under receiver operating characteristic for HVPG ≥ 12 mmHg was 0.62. Betablockers were stopped permanently in 10/13 patients with gradient < 12 mmHg, with no bleeding episodes after a median follow-up of 68 wk. CONCLUSION: Portal hypertension dropped below the bleeding threshold in 39% of patients more than one year after antiviral treatment. Endoscopy and transient elastography are inaccurate for reliable detection of this change. Stopping betablockers permanently seems uneventful in patients with a gradient < 12 mmHg.

RESUMO

BACKGROUND: The efficacy of licensed direct-acting antiviral (DAA) regimens is assumed to be the same for hepatitis C virus (HCV)-monoinfected patients (HCV-Mono) and HIV/HCV-coinfected patients (HCV-Co). However, the high sustained viral response (SVR) rates of DAA regimens and the small number of HIV-infected patients included in registration trials have made it difficult to identify predictors of treatment failure, including the presence of HIV. METHODS: We compared treatment outcomes for ledipasvir/sofosbuvir (LDV/SOF) against HCV G1 in treatment-naïve HCV-Mono and HCV-Co without cirrhosis in a prospective registry of individuals receiving DAAs for HCV. RESULTS: Up to September 2017, a total of 17 269 patients were registered, and 1358 patients (1055 HCV-Mono/303 HCV-Co) met the inclusion criteria. Significant differences between HCV-Mono and HCV-Co were observed for age, gender, and G1 subtype distribution. Among HCV-Co, 99.0% were receiving antiretroviral therapy. SVR rates for LDV/SOF at 8 weeks did not differ significantly between HCV-Mono and HCV-Co (96.9% vs 94.0%; P = .199). However, the SVR rate for LDV/SOF at 12 weeks was significantly higher for HCV-Mono than HCV-Co (97.2% vs 91.8%; P = .001). A multivariable logistic regression model including age, sex, liver stiffness, G1 subtype, HCV-RNA, HIV, and treatment duration showed the factors associated with treatment failure to be male sex (adjusted odds ratio [aOR], 2.49; 95% confidence interval [CI], 1.27-4.91; P = .008) and HIV infection (aOR, 2.23; 95% CI, 1.13-4.38; P = .020). CONCLUSIONS: The results of this large prospective study analyzing outcomes for LDV/SOF against HCV G1 in treatment-naïve noncirrhotic patients suggest that HIV infection is a predictor of treatment failure in patients with chronic hepatitis C.
