ABSTRACT

BACKGROUND & OBJECTIVES: This study aimed to: 1) analyze the inflammatory profile of Rheumatoid Arthritis (RA) patients, identifying clinical phenotypes associated with cardiovascular (CV) risk; 2) evaluate biologic and targeted-synthetic disease-modifying antirheumatic drugs (b-DMARDs and ts-DMARDs': TNFi, IL6Ri, JAKinibs) effects; and 3) characterize molecular mechanisms in immune-cell activation and endothelial dysfunction. PATIENTS & METHODS: A total of 387 RA patients and 45 healthy donors were recruited, forming three cohorts: i) 208 RA patients with established disease but without previous CV events; ii) RA-CVD: 96 RA patients with CV events, and iii) 83 RA patients treated with b-DMARDs/ts-DMARDs for 6 months. Serum inflammatory profiles (cytokines/chemokines/growth factors) and NETosis/oxidative stress-linked biomolecules were evaluated. Mechanistic in vitro studies were performed on monocytes, neutrophils and endothelial cells (EC). RESULTS: In the first RA-cohort, unsupervised clustering unveiled three distinct groups: cluster 3 (C3) displayed the highest inflammatory profile, significant CV-risk score, and greater atheroma plaques prevalence. In contrast, cluster 1 (C1) exhibited the lowest inflammatory profile and CV risk score, while cluster 2 (C2) displayed an intermediate phenotype. Notably, 2nd cohort RA-CVD patients mirrored C3's inflammation. Treatment with b-DMARDs or ts-DMARDs effectively reduced disease-activity scores (DAS28) and restored normal biomolecules levels, controlling CV risk. In vitro, serum from C3-RA or RA-CVD patients increased neutrophils activity and CV-related protein levels in cultured monocytes and EC, which were partially prevented by pre-incubation with TNFi, IL6Ri, and JAKinibs. CONCLUSIONS: Overall, analyzing circulating molecular profiles in RA patients holds potential for personalized clinical management, addressing CV risk and assisting healthcare professionals in tailoring treatment, ultimately improving outcomes.

ABSTRACT

BACKGROUND: /Objective: Sleep-disordered breathing (SDB) may change from the acute to stable phase of some cardiovascular disorders, but little is known whether these dynamic changes also exist in pulmonary embolism (PE). This study aimed to analyze the changes in the apnea-hypopnea index (AHI) from the acute to stable phase of PE as well as the factors associated. PATIENTS/METHODS: We conducted a prospective, longitudinal and multicenter study of consecutive adults requiring hospitalization for non-hypotensive acute PE, with a protocol including clinical, imaging (transthoracic echocardiography [TTE] and computed tomography), blood tests and a sleep study within 48 h of diagnosis of PE. After 3 months of follow-up, the sleep study was repeated. Right ventricular (RV) dysfunction was defined according to TTE criteria. RESULTS: One hundred and eleven patients (mean age [SD]: 63 [15] years; body mass index: 28.4 [4.7] kg/m2) were included. The initial AHI was 24.4 (21.8) events/h (AHI≥5: 82.8 %; AHI≥30: 33.3 %). Seventy-seven patients (69.4 %) had RV dysfunction. In the overall cohort, the AHI decreased by 8.7 events/h from the acute to stable phase (24.4/h vs. 15.7/h; p=0.013). Patients with RV dysfunction showed a greater decrease in AHI (mean decrease 12.3/h vs. 0.43/h). In the multivariable analysis a drop of an AHI≥5 events/hour was independently associated with the presence of initial RV dysfunction (hazard ratio 3.9; 95%CI 1.3 to 12.1). CONCLUSIONS: In hemodynamically stable patients with acute PE, there is a transient but clinically significant decrease in the AHI from the acute to stable phase, particularly when initially presenting with RV dysfunction.

ABSTRACT

BACKGROUND: Heart transplantation (HT) is the reference treatment for patients with terminal heart failure. In recent years there has been a progressive increase in HT procedures in patients who have a circulatory support (CS). METHODS: This is a retrospective single-center study of 293 consecutive patients who underwent HT from 2009 to 2018, analyzing the evolution of the 2 cohorts: patients with and without CS as a bridge to HT. Baseline and evolutionary clinical data collected following the usual follow-up protocol were recorded, including clinical events observed during the follow-up 1 year after the procedure. RESULTS: The subgroup of patients transplanted with CS showed a higher incidence of primary graft failure, frequent infection, and mortality. A tendency toward lower cardiac allograft vasculopathy was observed in this subgroup. Mechanical ventilation added to the CS resulted in a higher incidence of primary graft failure, infection, and renal dysfunction. The CS variable as a bridge to HT was shown to be predictive of 1-year mortality in both univariate (odds ratio, 1.84; 95% confidence interval, 1.03-3.3; P = .038) and multivariate (odds ratio, 2.1; 95% confidence interval, 1.01-4.3; P = .047) analyses. CONCLUSIONS: In our experience, CS as a bridge to HT results in a higher incidence of primary graft failure, frequent infection, and mortality at 1-year follow-up. Mechanical ventilation added to CS has a clear unfavorable prognostic impact. CS as a bridge to HT was shown to be predictive of 1-year mortality in both univariate and multivariate analyses.

ABSTRACT

Abstract Introduction: Patients undergoing cardiac surgery frequently develop low cardiac output syndrome (LCOS). Multiple interventions including levosimendan have been used in the prevention and treatment of LCOS. Preliminary studies reported lower mortality respect to placebo or other inotropes, however, recently, 3 clinical trials found no benefit against this outcome. Objective: Our objective was to evaluate the evidence of levosimendan on mortality and secondary outcomes in patients undergoing cardiac surgery, and to determine the sources of heterogeneity. Methods: We conducted a systematic review and meta-analysis of the clinical trials that evaluated the efficacy of levosimendan in patients undergoing cardiac surgery. We obtained the odds ratio (OR) of mortality and other outcomes such as kidney injury with dialysis requirement and LCOS, using fixed and random effects models. The risk of bias was assessed and the sources of heterogeneity were explored. Results: Of 47 studies identified, 14 studies were selected (n=2752). Regarding the mortality outcome and use of levosimendan, only a decrease was found in the studies of low quality (OR 0,30; CI 95%, 0,18 to 0,51). While high-quality studies, there was no protective effect (OR 0.99,95% CI 0.70-1.40) with an I2 = 0%. The quality of the studies and ejection fraction were the main sources of heterogeneity. Conclusion: In high-quality studies, the use of levosimendan in patients undergoing cardiovascular surgery has no effect on 30-day mortality. There was a protective effect on postoperative renal failure with dialysis.


Resumen Introducción: Los pacientes llevados a cirugía cardiaca tienen riesgo de desarrollar síndrome de bajo gasto cardiaco posoperatorio (SBGC). Estudios previos han encontrado una menor mortalidad con levosimendán respecto a placebo u otros inotrópicos; sin embargo, tres experimentos clínicos no encontraron beneficio frente a este desenlace. Objetivo: Evaluar la evidencia del levosimendán sobre la mortalidad y los desenlaces secundarios en pacientes sometidos a cirugía cardiaca, y determinar las fuentes de heterogeneidad. Métodos: Mediante una revisión sistemática y metaanálisis de los experimentos clínicos que evaluaron la eficacia del levosimendán en los pacientes llevados a cirugía cardiaca, se evaluó la eficacia en la mortalidad y en otros desenlaces, como lesión renal y SBGC, utilizando los modelos de efectos fijos y aleatorios. Resultados: De 47 estudios identificados, fueron seleccionados 14 (n = 2752). Respecto al desenlace de mortalidad y el uso de levosimendán solo se encontró una disminución en los estudios de baja calidad (OR 0.30; IC 95%, 0.18-0.51), mientras que para los de alta calidad no hubo efecto protector (OR 0.99; IC 95%, 0.70-1.40) con un I2=0%. La calidad de los estudios y la fracción de eyección fueron las principales fuentes de heterogeneidad. Conclusión: el uso del levosimendán en los pacientes llevados a cirugía cardiovascular no tiene efectos sobre la mortalidad a 30 días en los estudios de alta calidad. Hubo efecto protector sobre la falla renal postoperatoria con necesidad de diálisis.

ABSTRACT

The idiopathic retinitis, vasculitis, aneurysms and neuroretinitis syndrome is a rare retinal vascular disorder characterized by multiple leaking aneurysmal dilations, retinal vasculitis, neuroretinitis and peripheral vascular ischemia. Visual loss mainly occurs due to the development of retinal neovascularization and/or exudative maculopathy. Although the treatment of choice has not yet been established, retinal photocoagulation seems to be the best option to control the disease and to prevent its progression. Herein, we report a case of idiopathic retinitis, vasculitis, aneurysms and neuroretinitis syndrome with both retinal neovascularization and macular exudation successfully managed with intravitreal ranibizumab (Lucentis(®)) as adjunctive therapy to retinal photocoagulation.
