ABSTRACT
BACKGROUND: Critical illness is a major ongoing health care burden worldwide and is associated with high mortality rates. Sodium-glucose cotransporter-2 inhibitors have consistently shown benefits in cardiovascular and renal outcomes. The effects of sodium-glucose cotransporter-2 inhibitors in acute illness have not been properly investigated. METHODS: DEFENDER is an investigator-initiated, multicenter, randomized, open-label trial designed to evaluate the efficacy and safety of dapagliflozin in 500 adult participants with acute organ dysfunction who are hospitalized in the intensive care unit. Eligible participants will be randomized 1:1 to receive dapagliflozin 10mg plus standard of care for up to 14 days or standard of care alone. The primary outcome is a hierarchical composite of hospital mortality, initiation of kidney replacement therapy, and intensive care unit length of stay, up to 28 days. Safety will be strictly monitored throughout the study. CONCLUSION: DEFENDER is the first study designed to investigate the use of a sodium-glucose cotransporter-2 inhibitor in general intensive care unit patients with acute organ dysfunction. It will provide relevant information on the use of drugs of this promising class in critically ill patients. CLINICALTRIALS.GOV REGISTRY: NCT05558098.

RESUMO Antecedentes: A doença crítica é um importante ônus permanente da assistência médica em todo o mundo e está associada a altas taxas de mortalidade. Os inibidores do cotransportador de sódio-glicose do tipo 2 têm demonstrado consistentemente benefícios nos desfechos cardiovasculares e renais. Os efeitos dos inibidores do cotransportador de sódio-glicose do tipo 2 em doenças agudas ainda não foram devidamente investigados. Métodos: O DEFENDER é um estudo de iniciativa do investigador, multicêntrico, randomizado, aberto, desenhado para avaliar a eficácia e a segurança da dapagliflozina em 500 participantes adultos com disfunção orgânica aguda hospitalizados na unidade de terapia intensiva. Os participantes aptos serão randomizados 1:1 para receber 10mg de dapagliflozina e o tratamento padrão por até 14 dias ou apenas o tratamento padrão. O desfecho primário é um composto hierárquico de mortalidade hospitalar, início de terapia renal substitutiva e tempo de internação na unidade de terapia intensiva, até 28 dias. O monitoramento da segurança será rigoroso durante todo o estudo. Conclusão: O DEFENDER é o primeiro estudo desenvolvido para investigar o uso de um inibidor do cotransportador de sódio-glicose do tipo 2 em pacientes de unidade de terapia intensiva geral com disfunção orgânica aguda. O estudo fornecerá informações relevantes sobre o uso de medicamentos dessa classe promissora em pacientes críticos. Registro ClincalTrials.gov: NCT05558098
ABSTRACT
AIMS: To evaluate whether a strategy of double-dose influenza vaccination during hospitalization for an acute coronary syndrome (ACS) compared with standard-dose outpatient vaccination (as recommended by current guidelines) would further reduce the risk of major cardiopulmonary events. METHODS AND RESULTS: Vaccination against Influenza to Prevent cardiovascular events after Acute Coronary Syndromes (VIP-ACS) was a pragmatic, randomized, multicentre, active-comparator, open-label trial with blinded outcome adjudication comparing two strategies of influenza vaccination following an ACS: double-dose quadrivalent inactivated vaccine before hospital discharge vs. standard-dose quadrivalent inactivated vaccine administered in the outpatient setting 30 days after randomization. The primary outcome was a hierarchical composite of all-cause death, myocardial infarction, stroke, unstable angina, hospitalization for heart failure, urgent coronary revascularization, and hospitalization for respiratory causes, analysed by the win ratio method. Patients were followed for 12 months. During two influenza seasons, 1801 participants were included at 25 centres in Brazil. The primary outcome was not different between groups, with 12.7% wins in-hospital double-dose vaccine group and 12.3% wins in the standard-dose vaccine group {win ratio: 1.02 [95% confidence interval (CI): 0.79-1.32], P = 0.84}. Results were consistent for the key secondary outcome, a hierarchical composite of cardiovascular death, myocardial infarction and stroke [win ratio: 0.94 (95% CI: 0.66-1.33), P = 0.72]. Time-to-first event analysis for the primary outcome showed results similar to those of the main analysis [hazard ratio 0.97 (95% CI: 0.75-1.24), P = 0.79]. Adverse events were infrequent and did not differ between groups. CONCLUSION: Among patients hospitalized with an ACS, double-dose influenza vaccination before discharge did not reduce cardiopulmonary outcomes compared with standard-dose vaccination in the outpatient setting.
