Effectiveness and tolerability of dolutegravir/lamivudine for the treatment of HIV-1 infection in clinical practice.

OBJECTIVES: To assess the effectiveness and tolerability of dolutegravir (DTG)/lamivudine (3TC) among treatment-naive and virologically suppressed treatment-experienced individuals in the multicentre cohort of the Spanish HIV/AIDS Research Network (CoRIS) during the years 2018-2021. METHODS: We used multivariable regression models to compare viral suppression (VS) [HIV RNA viral load (VL) <50 copies/mL] and the change in CD4 cell counts at 24 and 48 (±12) weeks after initiation with dolutegravir/lamivudine or other first-line ART regimens. RESULTS: We included 2160 treatment-naive subjects, among whom 401 (18.6%) started with dolutegravir/lamivudine. The remaining subjects started bictegravir (BIC)/emtricitabine (FTC)/tenofovir alafenamide (TAF) (n = 949, 43.9%), DTG + FTC/tenofovir disoproxil fumarate (TDF) (n = 282, 13.1%), DTG/3TC/abacavir (ABC) (n = 255, 11.8%), darunavir (DRV)/cobicistat(COBI)/FTC/TAF (n = 147, 6.8%) and elvitegravir (EVG)/COBI/FTC/TAF (n = 126, 5.8%). At 24 and 48 weeks after starting dolutegravir/lamivudine, 91.4% and 93.8% of the subjects, respectively, achieved VS. The probability of achieving VS with dolutegravir/lamivudine was not significantly different compared with any other regimen at 24 or 48 weeks, with the exception of a lower chance of achieving VS at 24 weeks for DRV/COBI/FTC/TAF (adjusted OR: 0.47; 95% CI: 0.30-0.74) compared with dolutegravir/lamivudine.For the analysis of treatment-experienced virally suppressed subjects we included 1456 individuals who switched to dolutegravir/lamivudine, among whom 97.4% and 95.5% maintained VS at 24 and 48 weeks, respectively. During the first 48 weeks after dolutegravir/lamivudine initiation, 1.0% of treatment-naive and 1.5% of treatment-experienced subjects discontinued dolutegravir/lamivudine due to an adverse event. CONCLUSIONS: In this large multicentre cohort, effectiveness and tolerability of dolutegravir/lamivudine were high among treatment-naive and treatment-experienced subjects.

Colchicine in Recently Hospitalized Patients with COVID-19: A Randomized Controlled Trial (COL-COVID).

BACKGROUND: Colchicine has been proposed as a potential therapy in coronavirus disease 2019 (COVID-19) due to their anti-inflammatory actions. METHODS: The COL-COVID study was a prospective, randomized, controlled and open-label clinical trial that compared colchicine added to standard treatment vs standard treatment in hospitalized COVID-19 patients that do not need mechanical ventilatory support. Colchicine was initiated within the first 48 hours of admission at a 1.5 mg loading dose, followed by 0.5 mg b.i.d. for one week and 0.5 mg per day for 28 days. The study endpoints were clinical status (7-points WHO ordinal scale) and inflammatory biomarkers (IL-6 and CRP). RESULTS: A total of 103 patients (51±12 years, 52% male) were randomly allocated to colchicine arm (n=52) and control arm (n=51). At day 28, all patients in the colchicine group were alive and discharged, whereas in the control group, two patients died in-hospital and one patient remained hospitalized. Clinical improvement in terms of changes on WHO scale at day 14 and 28 and time to 1-point clinical improvement did not differ between the two groups. Clinical deterioration (increase of at least 1-point in WHO scale) was observed in a higher proportion of cases in colchicine group (13.8%) vs control group (5.8%) (p=0.303); after adjustment by baseline risk factors and concomitant therapies, colchicine therapy was associated with a lower risk of clinical deterioration (p=0.030). Inflammatory biomarkers CRP and IL-6 concentrations course did not differ between the two arms. CONCLUSION: In hospitalized COVID-19 patients, colchicine treatment neither improved the clinical status, nor the inflammatory response, over the standard treatment. Nevertheless, a preventive effect for further clinical deterioration might be possible. TRIAL REGISTRATION: NCT04350320.

Mortality in Perinatally HIV-infected Adolescents After Transition to Adult Care in Spain.

INTRODUCTION: After the introduction of combination antiretroviral treatment, (ART) mortality in HIV-infected patients has dramatically decreased. However, it is still high in patients at risk, as adolescents transitioning to adult care (AC) without virologic control. The aim of this study was to characterize mortality and comorbidities of perinatally infected HIV (PHIV) patients after transition to AC. METHODS: A multicenter retrospective study from patients included in the CoRISpe-FARO Spanish cohort was conducted. PHIV patients who died after transition to AC between 2009 and 2019 were included. Clinical, immunovirologic characteristics, treatments received, comorbidities and causes of death were described. RESULTS: Among 401 PHIV patients, 14 died (3.5%). All were Spanish, 11/14 (78.6%) women. The median age at diagnosis was 1.5 years (interquartile range [IQR] 0.5-3.9), at transfer to AC was 18 years [16.1-19.9] and at death was 25.8 years [23.6-27.1]. In pediatric units [pediatric care (PC)], CD4+ nadir was 85 cells/µL [IQR 9.7-248.5] and 6/14 patients were classified as C-clinical stage. During AC, all patients were on C-clinical stage and CD4+ nadir dropped to 11.5 cells/µL [4.5-43.3]. cART adherence was extremely poor: in PC, 8/14 patients registered voluntary treatment interruptions; only one had undetectable VL at transition. In AC, 12/14 patients stopped treatment 2 or more periods of time. All deaths were related to advanced HIV disease. Mental health disorders were observed in 7/14 (50%). Main complications described: recurrent bacterial infections (57.1%), wasting syndrome (42.9%), esophageal candidiasis (28.6%) and Pneumocystis jirovecii pneumonia (28.6%). Four women had 11 pregnancies; 5 children were born (none infected). CONCLUSIONS: Young adults PHIV infected who transition to AC without virologic suppression or proven ability to adhere to ART are at high risk of mortality. Mortality was noted as a consequence of advanced HIV disease, frequent mental health problems and poor adherence to ART.

Aortic valve stenosis provides complementary information to bleeding risk scores in non-valvular atrial fibrillation patients initiating anticoagulation.

BACKGROUND: The identification of modifiable bleeding risk factors may be of relevance. The aim is to evaluate if aortic stenosis (AS) provides additional information to bleeding risk scores for predicting major bleeding (MB) in non-valvular atrial fibrillation (AF). METHODS: We designed a retrospective multi-center study including 2880 consecutive non-valvular AF patients initiating oral anticoagulation between January 2013 and December 2016. AS was defined as moderate or severe according to European echocardiography guidelines criteria. HASBLED, ATRIA and ORBIT scores were used to evaluate the bleeding risk. MB was defined according to the International Society on Thrombosis and Haemostasia criteria and registered at 18 months of follow-up. RESULTS: 168 (5.8%) patients had AS. Patients with AS had higher risk for MB compared to those without AS (HR = 2.13, 95% CI: 1.40-3.23, P < 0.001). Patients without AS and low-intermediate bleeding risk (0 points) showed the lowest MB rate, whereas the MB rate observed among patients with AS and high bleeding risk (2 points) was the highest one. Discrimination and reclassification analyses showed that AS provided additional information to bleeding risk scores for predicting MB at 18 months of follow-up. CONCLUSIONS: In this population, AS was associated with an increased risk for MB at midterm follow-up. The three scoring systems showed a moderate discriminatory ability for MB. Moreover, the addition of AS was associated with a significant improvement in their predictive accuracy. We suggest that the presence of this valvulopathy should be taken into account for bleeding risk assessment.

Prevalencia e implicación pronóstica de la enfermedad valvular en pacientes con fibrilación auricular que inician anticoagulantes orales / Prevalence and prognostic implications of valve disease in patients with atrial fibrillation initiating direct oral anticoagulants

Introducción y objetivos: La enfermedad valvular en los pacientes con fibrilación auricular incluidos en los ensayos clínicos con anticoagulantes orales directos (ACOD) es frecuente y se asocia con peor pronóstico. El objetivo es evaluar la prevalencia de valvulopatía y su influencia en los eventos clínicos en la práctica clínica real. Métodos: Registro multicéntrico retrospectivo que incluyó a 2.297 pacientes consecutivos con fibrilación auricular no valvular que iniciaron tratamiento con ACOD entre enero de 2013 y diciembre de 2016. La enfermedad valvular se definió como afección moderada o grave. El evento principal fue la combinación de muerte, ictus o accidente isquémico transitorio/embolia sistémica o hemorragia mayor. Se realizó un análisis de riesgos competitivos mediante un modelo de regresión de Fine y Gray, con la muerte como evento competitivo. Resultados: Tenían valvulopatía 499 pacientes (21,7%), y la insuficiencia mitral fue la más frecuente (13,7%). Los pacientes con valvulopatía eran de más edad y con mayor comorbilidad. Tras el análisis multivariable, la enfermedad valvular fue predictora del evento combinado (HR=1,54; IC95%, 1,22-1,94; p<0,001), muerte (HR=1,44; IC95%, 1,09-1,91, p=0,010) y hemorragia mayor (HR=1,85; IC95%, 1,23-2,79, p=0,003), pero no de eventos tromboembólicos (p >0,05). Conclusiones: En pacientes con fibrilación auricular no valvular que inician tratamiento con ACOD, la enfermedad valvular es frecuente y se asocia con mayor riesgo de muerte, ictus o accidente isquémico transitorio/embolia sistémica o complicaciones hemorrágicas. Estos hallazgos confirman los resultados de los ensayos clínicos y los expande al ámbito de la práctica clínica real

Introduction and objectives: Valvular heart disease in patients with atrial fibrillation included in clinical trials with direct oral anticoagulants (DOAC) is common and is associated with worse prognosis. The aim of this study was to evaluate the prevalence of valvular heart disease and its influence on clinical events in real-world clinical practice. Methods: We conducted a retrospective multicenter registry including 2297 consecutive patients with nonvalvular atrial fibrillation initiating DOAC between January 2013 and December 2016. Valvular heart disease was defined as moderate or severe involvement. The primary study endopoint was the composite of death, stroke or transient ischemic attack/systemic embolism or major bleeding. A competing risks analysis was carried out using a Fine and Gray regression model, with death being the competing event. Results: A total of 499 (21.7%) patients had significant valvular heart disease. The most common form was mitral regurgitation (13.7%). Patients with valvular heart disease were older and had more comorbidities. After multivariable analysis, valvular heart disease was associated with a higher risk for the primary endpoint (HR, 1.54; 95%CI, 1.22-1.94; P<.001), death (HR, 1.44; 95%CI, 1.09-1.91, P=.010), and major bleeding (HR, 1.85; 95%CI, 1.23-2.79, P=.003), but there was no association with thromboembolic events (P >.05). Conclusions: In patients with nonvalvular atrial fibrillation initiating DOACs, valvular heart disease is common and increases the risk of mortality, stroke, transient ischemic attack/systemic embolism, and major bleeding complications. These findings confirm the results of clinical trials and expand them to a real-life clinical setting

Effect of concomitant antiplatelet therapy in patients with nonvalvular atrial fibrillation initiating non-vitamin K antagonists.

BACKGROUND: Antiplatelet therapy (APT) use in combination with oral anticoagulation is common among patients with atrial fibrillation, but there is scarce information regarding its effect on outcomes in patients on non-vitamin K antagonist oral anticoagulants (NOAC). We aimed to evaluate the safety and efficacy of APT use in a 'real-world' cohort of nonvalvular atrial fibrillation (NVAF) patients initiating NOAC. DESIGN: We conducted a retrospective multicentre study including 2361 consecutive NVAF patients initiating NOAC between January 2013 and December 2016. Patients with an acute ischaemic event within the last 12 months (acute coronary syndrome, stroke or revascularization) were excluded. Patients were followed up, and all clinical events were recorded at 3 months. The primary outcome of the study was major bleeding, and the secondary outcomes were stroke, nonfatal myocardial infarction, intracranial bleeding and death. RESULTS: One hundred forty-five (6.1%) patients received concomitant APT, and aspirin was the more common (79%). At 3 months, 25 (1.1%) patients had major bleeding, 8 (0.3%) had nonfatal myocardial infarction, 7 (0.3%) had ischaemic stroke, and 40 (1.7%) died. After multivariate adjustment, concomitant APT was associated with higher risk for major bleeding (HR = 3.62, 95% CI 1.32-9.89; P = .012), but was not associated with a higher risk of other clinical outcomes. CONCLUSIONS: Concomitant APT use is uncommon among these patients and does not seem to be associated with lower rates of ischaemic events or death. However, there are signals for an increased risk of bleeding, which reinforces current guideline recommendations.

Effectiveness and safety of rivaroxaban in nonvalvular atrial fibrillation: data from a contemporary Spanish registry.

Objective: To ascertain the clinical profile, management and rates of thromboembolic and bleeding complications in a contemporary cohort of patients with nonvalvular atrial fibrillation (NVAF) on rivaroxaban treatment, with a particular focus on some subgroups of patients. Methods: Retrospective study that included all NVAF patients who started treatment with rivaroxaban for the prevention of stroke or systemic embolism between December 2012 and December 2015. Rates of outcomes (stroke, nonfatal myocardial infarction, major bleeding, intracranial bleeding and death) during follow-up were calculated. Results: A total of 732 patients (mean age 76.4 ± 9.2 years; 54.5% women) were included. Comorbidities were common (hypertension 87.5%; diabetes 26.5%; renal insufficiency 24.6%; prior stroke/transient ischemic attack 16.8%). Mean CHA2DS2-VASc was 3.9 ± 1.5 and HAS-BLED 2.3 ± 0.9; 61.9% of patients were rivaroxaban naïve users. After a mean treatment period of 22.7 ± 7.4 months, rates of stroke, nonfatal myocardial infarction, major bleeding, intracranial bleeding and death were 1.8, 1.0, 3.2, 0.4 and 5.5 events per 100 patient-years, respectively. Rates of stroke and death were higher in patients >75 years (vs. ≤75 years) and in patients with prior stroke/transient ischemic attack or renal insufficiency. Rates of major bleeding were higher among patients >75 years and in patients with prior stroke/transient ischemic attack. Conclusions: In this contemporary Spanish cohort of NVAF patients on rivaroxaban, patients had many comorbidities, a high thromboembolic risk and a moderate bleeding risk. Overall, rates of stroke and bleeding complications were low and similar to other previous studies. These data suggest that rivaroxaban is effective and safe in routine practice.

Kidney function monitoring and nonvitamin K oral anticoagulant dosage in atrial fibrillation.

BACKGROUND: Clinical practice guidelines recommend regular kidney function monitoring in atrial fibrillation patients on nonvitamin K oral anticoagulants (NOAC); however, information regarding compliance with these recommendations in daily life conditions is scarce. We sought to determine the compliance with kidney function monitoring recommendations in nonvalvular atrial fibrillation (NVAF) patients starting NOAC and its implication on the appropriateness of NOAC dosage. MATERIAL AND METHODS: This study involves the retrospective analysis of a multicentre registry including consecutive NVAF patients who started NOAC (n = 692). Drug dosage changes and serum creatinine determinations were recorded during 1-year follow-up. European Heart Rhythm Association criteria were used to define the appropriateness of kidney function monitoring as well as adequate NOAC dosage. RESULTS: During the follow-up (334 ± 89 days), the compliance with kidney function monitoring recommendations was 61% (n = 425). After multivariate adjustment, age (OR × year: 0.92 (CI 95%: 0.89-0.95) P < .001), creatinine clearance (OR × mL/min: 1.02 (CI 95%: 1.01-1.03) P < .001) and adequate NOAC dosage at baseline (OR: 1.54 (CI 95%: 1.06-2.23), P = .024) were independent predictors of appropriate kidney function monitoring. Compliance with kidney function monitoring recommendations was independently associated with change to appropriate NOAC dose after 1 year (OR: 2.80 (CI 95%: 1.01-7.80), P = .049). CONCLUSIONS: Noncompliance with kidney function monitoring recommendations is common in NVAF patients starting NOAC, especially in elderly patients with kidney dysfunction. Compliance with kidney function monitoring recommendations was associated with adequate NOAC dosage at 1-year follow-up. Further studies are warranted to evaluate the implication of kidney function monitoring on prognosis.
