Evolución temporal en el tratamiento transcatéter de la estenosis aórtica: análisis del registro español de TAVI

Introduction and objectives: This study primary endpoint was to present the in-hospital all-cause mortality of the Spanish TAVI registry from its inception until 2018. Secondary endpoints included other in-hospital clinical events, 30-day all-cause mortality, and an assessment of the time trend of this registry. Methods: All consecutive patients included in the Spanish TAVI registry were analyzed. In this time-based analysis, the population was been divided into patients treated before 2014 (cohort A: 2009-2013) and patients treated between 2014 and 2018 (cohort B). Results: From August 2007 to June 2018, 7180 patients were included. The mean age was 81.2 ± 6.5 years and 53% were women. The logistic EuroSCORE was 12% (8-20). Transfemoral access was used in 89%. In-hospital and 30-day all-cause mortality was 4.7% and 5.7%, respectively. On the time-based analyses during the hospital stay, the rate of myocardial infarction, stroke, need for pacemakers, tamponade, coronary obstruction, and vascular complications was similar between both groups. However, cohort B showed less need for conversion to surgery and malapposition of the valve. Also, the implant success rate increased from 93% to 96% (P < .001). In-hospital and 30-day all-cause mortality was significantly lower in cohort B, ([OR, 0.65; IC95%, 0.48-0.86; P = .003] and [OR, 0.71; IC95%, 0.54-0.92; P = .002], respectively). Conclusions: The time trend analysis of the Spanish TAVI registry showed a change in the patients’ clinical profile and an improvement in the in-hospital clinical outcomes and 30-day all-cause mortality in patients treated more recently.Introducción y objetivos: El objetivo primario de este estudio fue presentar la mortalidad total intrahospitalaria del registro español de implante percutáneo de válvula aórtica (TAVI) desde su inicio hasta el año 2018, y como objetivos secundarios otros eventos clínicos intrahospitalarios, la mortalidad total a los 30 días y la evaluación de cuál ha sido la evolución temporal de este registro. Métodos: Fueron analizados todos los pacientes consecutivos incluidos en el registro español de TAVI. En este análisis temporal se dividió la población en pacientes tratados antes de 2014 (cohorte A: 2009-2013) y pacientes tratados entre los años 2014 y 2018 (cohorte B). Resultados: Desde agosto de 2007 hasta junio de 2018 se incluyeron 7.180 pacientes. La edad media fue de 81,2 ± 6,5 años y el 53% eran mujeres. El EuroSCORE logístico fue del 12% (8-20). Se utilizó un acceso transfemoral en el 89%. La mortalidad total intrahospitalaria fue del 4,7% y a los 30 días fue del 5,7%. En el análisis temporal durante la fase hospitalaria, las tasas de infarto, accidente cerebrovascular, necesidad de marcapasos, taponamiento, obstrucción coronaria y complicaciones vasculares fueron similares en ambos grupos. Sin embargo, en la cohorte B se observó una reducción de la necesidad de conversión a cirugía y de mala posición de la válvula, y además la tasa de éxito del implante fue mayor (93 frente a 96%; p < 0,001). La mortalidad por cualquier causa ajustada tanto intrahospitalaria como a los 30 días, fue significativamente menor en la cohorte B (odds ratio [OR] = 0,65; intervalo de confianza del 95% [IC95%], 0,48-0,86; p = 0,003; y OR = 0,71; IC95%, 0,54-0,92; p = 0,002, respectivamente). Conclusiones: En el análisis temporal del registro español de TAVI se observan un cambio en el perfil clínico de los pacientes y una mejora en la evolución clínica tanto intrahospitalaria como a los 30 días en los pacientes tratados en los últimos años

Comprehensive analysis and insights gained from long-term experience of the Spanish DILI Registry

Altres ajuts: Fondo Europeo de Desarrollo Regional (FEDER); Agencia Española del Medicamento; Consejería de Salud de Andalucía.Background & Aims: Prospective drug-induced liver injury (DILI) registries are important sources of information on idiosyncratic DILI. We aimed to present a comprehensive analysis of 843 patients with DILI enrolled into the Spanish DILI Registry over a 20-year time period. Methods: Cases were identified, diagnosed and followed prospectively. Clinical features, drug information and outcome data were collected. Results: A total of 843 patients, with a mean age of 54 years (48% females), were enrolled up to 2018. Hepatocellular injury was associated with younger age (adjusted odds ratio [aOR] per year 0.983; 95% CI 0.974-0.991) and lower platelet count (aOR per unit 0.996; 95% CI 0.994-0.998). Anti-infectives were the most common causative drug class (40%). Liver-related mortality was more frequent in patients with hepatocellular damage aged ≥65 years (p = 0.0083) and in patients with underlying liver disease (p = 0.0221). Independent predictors of liver-related death/transplantation included nR-based hepatocellular injury, female sex, higher onset aspartate aminotransferase (AST) and bilirubin values. nR-based hepatocellular injury was not associated with 6-month overall mortality, for which comorbidity burden played a more important role. The prognostic capacity of Hy's law varied between causative agents. Empirical therapy (corticosteroids, ursodeoxycholic acid and MARS) was prescribed to 20% of patients. Drug-induced autoimmune hepatitis patients (26 cases) were mainly females (62%) with hepatocellular damage (92%), who more frequently received immunosuppressive therapy (58%). Conclusions: AST elevation at onset is a strong predictor of poor outcome and should be routinely assessed in DILI evaluation. Mortality is higher in older patients with hepatocellular damage and patients with underlying hepatic conditions. The Spanish DILI Registry is a valuable tool in the identification of causative drugs, clinical signatures and prognostic risk factors in DILI and can aid physicians in DILI characterisation and management. Lay summary: Clinical information on drug-induced liver injury (DILI) collected from enrolled patients in the Spanish DILI Registry can guide physicians in the decision-making process. We have found that older patients with hepatocellular type liver injury and patients with additional liver conditions are at a higher risk of mortality. The type of liver injury, patient sex and analytical values of aspartate aminotransferase and total bilirubin can also help predict clinical outcomes
