RESUMEN

Introducción: Las últimas evidencias revelan que la infección por COVID-19 no tienen peor pronóstico en los pacientes con enfermedades inflamatorias inmunomediadas (EIMI), aunque desarrollan menor respuesta a la vacunación. Objetivo: Comparar la incidencia de COVID-19 y características clínicas en pacientes con EIMI entre la primera y sexta olas. Método: Estudio observacional prospectivo de 2 cohortes de pacientes con EIMI diagnosticados de COVID-19. Primera cohorte: marzo-mayo de 2020; segunda cohorte: diciembre/2021 a febrero/2022. Se recogieron variables sociodemográficas y clínicas, y en la segunda cohorte el estado de vacunación contra la COVID-19. El análisis estadístico estableció las diferencias de las características y la evolución clínica entre ambas cohortes. Resultados: De un total de 1.627 pacientes en seguimiento, contrajeron COVID-19 durante la primera ola 77 (4,60%) y 184 en la sexta (11,3%). En la sexta hubo menos hospitalizaciones, ingresos en cuidados intensivos y fallecimientos que en la primera (p=0,000) y 180 pacientes (97,8%) tenían al menos una dosis de vacuna. Conclusión: La detección precoz y la vacunación han evitado la aparición de complicaciones graves.(AU)


Introduction: Recent evidence shows that COVID-19 infection does not have a worse prognosis in patients with immune-mediated inflammatory diseases (IMID), although they develop a worse response to vaccination. Objective:To compare the incidence of COVID-19 and clinical features in patients with IMID between the first and sixth waves. Method: Prospective observational study of two cohorts of IMID patients diagnosed with COVID-19. First cohort March to May 2020, and second cohort December/2021 to February/2022. Sociodemographic and clinical variables were collected and, in the second cohort, COVID-19 vaccination status. Statistical analysis established differences in characteristics and clinical course between the two cohorts. Results: In total, 1627 patients were followed up, of whom 77 (4.60%) contracted COVID-19 during the first wave and 184 in the sixth wave (11.3%). In the sixth wave, there were fewer hospitalisations, intensive care unit admissions, and deaths than in the first wave (P=.000) and 180 patients (97.8%) had at least one dose of vaccine. Conclusion: Early detection and vaccination have prevented the occurrence of serious complications.(AU)

RESUMEN

Spain's rate of new human immunodeficiency virus (HIV) diagnoses exceeds that of the European Economic Area average (8.6 vs 5.6:100,000 in 2018). The country has failed to meet the first of United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 targets for HIV control by 2020, with 87.0% of people living with HIV knowing their status, and late presentation rates of 47.6% and 51.5% country-wide and in the Valencian autonomous community, respectively. Advancing screening and linkage to care (SLTC) practices is necessary to effectively control the epidemic. The Valencia Viral Screening (CRIVALVIR) project adopted the TEST model for opportunistic and systematic HIV SLTC in individuals aged 18 to 80 who required blood work for any purpose, as of February 2019. SLTC was integrated into routine clinical workflow across primary care centers serving a population of 360,000 people in Valencia, Spain. Our project successfully upscaled total HIV testing by 194% to over 32,000 patients tested in 14 months. We found an overall prevalence of 0.13% (0.08-0.21) among those screened per protocol (n = 13,061), with foreign-born citizens presenting a 12.5 times significantly higher likelihood of acquiring HIV (95% confidence interval 4.63-33.96, P < .0001). We improved late presentation by 18.2 percentage points and prevented an estimated 58 to 70 new secondary infections. HIV screening of the general population in primary care is an effective strategy for achieving timely diagnosis and preventing new infections. Opportunistic, systematic, opt-out approaches are essential to control the HIV epidemic.

RESUMEN

OBJECTIVE: To develop and assess the feasibility in daily practice of four comorbidity checklists, for common use in rheumatoid arthritis (RA), axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA). METHODS: A multidisciplinary panel of experts on comorbidity was established. Data from the GECOAR, GECOAX and GECOAP projects were analysed and a narrative literature review in Medline on RA, axSpA and PsA comorbidity was performed in order to select the most relevant and common comorbidities across the three diseases. With these results and those obtained from a focus group of patients, in a nominal group meeting, the experts generated preliminary checklists. These were afterwards modified by an external evaluation by two associations, a patients' association and an association of health professionals related to rheumatology. As a result, the final checklists were generated. A cross-sectional study was conducted to test the feasibility of three of the checklists in daily practice, in which eight health professionals evaluated the checklists in five patients with RA, five with axSpA and five with SpA. RESULTS: Four comorbidity checklists were designed, three for health professionals (one to assess current comorbidity, one on prevention/health promotion and one with the referral criteria to other health professionals), and another for patients. The feasibility study showed them to be simple, clear, and useful for use in routine clinical practice. CONCLUSIONS: The use of specific and common checklists for patients with RA, axSpA and PsA is feasible and might contribute favorably to their prognosis as well as in daily practice.

RESUMEN

OBJECTIVE: Speckle-tracking echocardiography (STE) deformation parameters detect latent LV dysfunction in chronic aortic regurgitation (AR) and are associated with outcomes. The aim of the study was to evaluate cardiac magnetic resonance (CMR) feature tracking (FT) deformation parameters in asymptomatic patients with AR and implications in outcomes. METHODS: Fifty-five patients with AR and 54 controls were included. Conventional functional CMR parameters, aortic regurgitant volume, and fraction were assessed. CMR-FT analysis was performed with a dedicated software. Clinical data was obtained from hospital records. A combined endpoint included all-cause mortality, cardiovascular mortality, aortic valve surgery, or cardiovascular hospital admission due to heart failure. RESULTS: Left ventricular (LV) mechanics is impaired in patients with significant AR. Significant differences were noted in global longitudinal strain (GLS) between controls and AR patients (- 19.1 ± 2.9% vs - 16.5 ± 3.2%, p < 0.001) and among AR severity groups (- 18.3 ± 3.1% vs - 16.2 ± 1.6% vs - 15 ± 3.5%; p = 0.02 for AR grades I-II, III, and IV). In univariate and multivariate analyses, circumferential strain (GCS) and global radial strain (GRS) but not GLS were associated with and increased risk of the end point with a HR of 1.26 (p = 0.016, 1.04-1.52) per 1% worsening for GCS and 0.90 (p = 0.012, 0.83-0.98) per 1% worsening for GRS. CONCLUSIONS: CMR-FT myocardial deformation parameters are impaired in patients with AR not meeting surgical criteria. GLS decreases early in the course of the disease and is a marker of AR severity while GCS and GRS worsen later but predict a bad prognosis, mainly the need of aortic valve surgery. KEY POINTS: • CMR feature tracking LV mechanic parameters may be reduced in significant chronic AR with normal EF. • LV mechanics, mainly global longitudinal strain, worsens as AR severity increases. • LV mechanics, specially global radial and circumferential strain, is associated with a worse prognosis in AR patients.

RESUMEN

INTRODUCCIÓN Y OBJETIVOS: Evaluar si una puntuación de riesgo genético (GRS) mejora la predicción de eventos recurrentes en pacientes jóvenes con infarto agudo de miocardio (IAM) e identifica una forma de aterosclerosis más agresiva. MÉTODOS: Se diseñó un estudio prospectivo con pacientes <55 años, no diabéticos, ingresados por IAM. Se realizó un test genético, una tomografía computarizada cardiaca y determinación de varios biomarcadores. Se analizó la asociación de un GRS compuesto por 11 variantes genéticas con la aparición de un objetivo primario combinado (muerte cardiovascular, evento recurrente u hospitalización cardiovascular). RESULTADOS: Se siguió a 81 pacientes durante una mediana de 4,1 años, y se documentaron 24 eventos. La prevalencia de variantes de riesgo fue superior en 9 de los 11 alelos frente a población general. El GRS se asoció con recurrencias, particularmente cuando los niveles basales de colesterol-LDL estaban elevados. En el modelo multivariado, teniendo como referencia el tercil de bajo riesgo genético, el HR para el grupo de riesgo intermedio fue de 10,2 (IC95% 1,1-100,3; p = 0,04) y de alto riesgo 20,7 (2,4-181,0; p = 0,006) si el colesterol-LDL era≥2,8 mmol/l (≥ 110mg/dl). La incorporación del GRS al modelo multivariado mejoró el estadístico C (ΔC-statistic=0,086), el cNRI (30%) y el IDI (0,05). El TC cardiaco detectó ateromatosis calcificada frecuentemente, pero tuvo un valor pronóstico limitado. No se detectó una asociación entre metaloproteinasas, GRS y recurrencias. CONCLUSIONES: En una población de pacientes jóvenes no diabéticos con IAM, una puntuación de riesgo genético puede predecir recurrencias y mejorar los modelos clínicos de estratificación pronóstica, especialmente en aquellos pacientes con colesterol-LDL basal elevado


INTRODUCTION AND OBJECTIVES: To evaluate whether a genetic risk score (GRS) improves prediction of recurrent events in young nondiabetic patients presenting with an acute myocardial infarction (AMI) and identifies a more aggressive form of atherosclerosis. METHODS: We conducted a prospective study with consecutive nondiabetic patients aged <55 years presenting with AMI. We performed a genetic test, cardiac computed tomography, and analyzed several biomarkers. We studied the association of a GRS composed of 11 genetic variants and a primary composite endpoint (cardiovascular mortality, a recurrent event, and cardiac hospitalization). RESULTS: A total of 81 patients were studied and followed up for a median of 4.1 years. There were 24 recurrent cardiovascular events. Compared with the general population, study participants had a higher prevalence of 9 out of 11 risk alleles. The GRS was significantly associated with recurrent cardiovascular events, especially when baseline low-density lipoprotein cholesterol (LDL-C) levels were elevated. Compared with the low-risk GRS tertile, the multivariate-adjusted HR for recurrences was 10.2 (95%CI, 1.1-100.3; P=.04) for the intermediate-risk group and was 20.7 (2.4-181.0; P=.006) for the high-risk group when LDL-C was≥2.8 mmol/L (≥ 110mg/dL). Inclusion of the GRS improved the C-statistic (ΔC-statistic=0.086), cNRI (continuous net reclassification improvement) (30%), and the IDI (integrated discrimination improvement) index (0.05). Cardiac computed tomography frequently detected coronary calcified atherosclerosis but had limited value for prediction of recurrences. No association was observed between metalloproteinases, GRS and recurrences. CONCLUSIONS: A multilocus GRS may identify individuals at increased risk of long-term recurrences among young nondiabetic patients with AMI and improve clinical risk stratification models, particularly among patients with high baseline LDL-C levels

RESUMEN

Left atrium (LA) size has an important role in determining prognosis and risk stratification in hypertrophic cardiomyopathy (HCM). Cardiovascular magnetic resonance myocardial feature tracking (CMR-FT) is a novel technique for the quantification of LA function. Our aim was first to evaluate LA function by CMR-FT and volumetric analysis in patients with HCM; and secondly we sought to determine the association of LA-longitudinal strain (LA-LS) with major cardiovascular outcomes, particularly all cause mortality and heart failure. 75 patients with HCM and 75 control subjects underwent a conventional CMR study including assessment of LA function by CMR-FT (LA-LS) and volumetric analysis. A primary endpoint of all-cause mortality and secondary combined endpoint of hospital admission related to heart failure, lethal ventricular arrhythmias or cardiovascular death were defined. Compared to controls, LA-LS and all volumetric indices of LA function were significantly impaired in HCM even in patients with normal LA volume and normal LV filling pressures. LA-LS showed moderate-high correlation with LA-emptying fraction (total, active and passive LA-EF, r = 0.68, r = 0.67, r = 0.31, p < 0.001 for all) and with parameters of diastolic function (E/é, r = 0.4, p < 0.001). The age, minimum LA volume and % of LGE were independent predictors of LA-LS (p < 0.01 for all). During a mean follow-up of 3.3 ± 1.2 years LA-LS was associated with the primary (HR: 0.85 (0.73-0.98), p = 0.02) and the secondary end-point (HR: 0.88 (0.82-0.96), p = 0.003). LA-LS by CMR-FT provides accurate measurements of LA function in HCM patients. LA-LS may become a novel potential predictor of poor cardiac outcomes, particularly cardiovascular mortality and HF.

RESUMEN

Extranodal natural killer/T-cell lymphoma is a rare non-Hodgkin lymphoma that is divided into nasal, non-nasal, and aggressive/leukemia subtypes, according to anatomic origin and clinical manifestations, with each subtype carrying a different prognosis. We present a case of primary cardiac natural killer/T-cell lymphoma with extension to other organs in a 38-year-old man, to highlight the role of imaging in categorizing nasal versus non-nasal types. This distinction has relevant implications for patient care because the non-nasal type has a much lower survival rate.

RESUMEN

BACKGROUND: Interstitial fibrosis, myocardial fiber disarray and non-uniform shortening are common histological features of hypertrophic cardiomyopathy (HCM). The degree of LV hypertrophy and fibrosis are postulated to contribute to the impairment of myocardial shortening. Cardiovascular magnetic resonance myocardial (CMR) feature tracking (CMR-FT) has emerged as a robust method that provides quantitative measurements of myocardial deformation. Our aim was first to evaluate LV strain parameters in HCM by CMR-FT and their dependence on both functional parameters and late gadolinium enhancement (LGE); and secondly we sought to determine their association with major cardiovascular outcomes. METHODS AND RESULTS: 74 patients with HCM and 75 controls subjects underwent a CMR study including LGE imaging. Global peak longitudinal, circumferential and radial systolic strain values (GLS, GCS, GRS) were measured by CMR-FT. A primary endpoint of all-cause mortality and secondary combined endpoint of hospital admission related to heart failure, lethal ventricular arrhythmias or cardiovascular death were defined. Patients with HCM showed attenuation of all LV strain values (p<0.001). Multivariate analysis showed that both LV hypertrophy and %of LGE were independent predictors of attenuated LV strains. All systolic LV strain parameters were impaired in patients with primary and secondary endpoints (follow up time: 25.6±9.9months, p<0.05 and p<0.01 respectively). Abnormal GLS, GCS and GRS were significantly associated with primary and secondary endpoints. CONCLUSION: Both LV hypertrophy and fibrosis contribute to the impairment of LV myocardial mechanics in HCM. In this population, reduced LV strain is associated with poor cardiac outcomes, particularly cardiovascular mortality and HF.

RESUMEN

BACKGROUND: Hypertrophic cardiomyopathy (HCM) remains the most common cause of sudden cardiac death (SCD) in the young; however, current strategies do not identify all HCM patients at risk. A novel validated algorithm was proposed by the last European Society of Cardiology guidelines to guide implantable cardioverter-defibrillator (ICD) therapy. Recently, extensive myocardial fibrosis was independently associated with increased risk of SCD events. This study aimed to establish the relation between myocardial fibrosis (late gadolinium enhancement [LGE] extension) and the novel SCD risk-prediction model in a real population of HCM to evaluate its potential additional value in the different risk groups. HYPOTHESIS: There is a significant association between LGE extension and the novel SCD risk calculator that may help conflicting ICD decisions. METHODS: Seventy-seven patients with HCM underwent routine clinical evaluation, echocardiography, and cardiac magnetic resonance study. Their SCD risk at 5 years was calculated using the new model. RESULTS: Extension of LGE positively correlated with SCD risk prediction (r = 0.7, P < 0.001). Low-, intermediate-, and high-risk groups according to the model showed significantly different extent of LGE (5% ± 6% vs 18% ± 9% vs 17% ± 4%; P < 0.001). Four patients (6%) in the low-risk group and 5 (62%) in the intermediate-risk group showed extensive areas of LGE. All patients except 1 (86%) at highest risk (n = 6) showed extensive areas of LGE. CONCLUSIONS: LGE extension is concordant with the novel SCD-risk model defining low- and high-risk groups; it may provide additional information, allowing better discrimination to support implantable cardioverter-defibrillator decision. LGE quantification holds promise for SCD stratification in HCM.
