RESUMO
Objetivo: Evaluar la asociación entre los niveles plasmáticos de soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) y la mortalidad de los pacientes con sepsis. Diseño: Estudio de cohortes prospectivo. Ámbito: Dos unidades de cuidados intensivos generales. Pacientes: Pacientes con sepsis en los que se determinaron los niveles plasmáticos de sTREM-1 durante los 3 primeros días de su presentación. Variables de interés principales: Mortalidad a los 28 días. Resultados: Se analizaron 121 pacientes (el 23% sepsis grave, el 44% shock séptico y el 33% sepsis no grave). La mortalidad a los 28 días fue del 24,8%. Los niveles de sTREM-1 iniciales fueron ligeramente más elevados en los fallecidos que en los supervivientes (mediana de 366,9 frente a 266,5pg/ml; p=0,2668). Una elevación de los niveles de sTREM-1 a lo largo de los 3 primeros días (delta-TREM) superior a 90pg/ml se asoció con un exceso de mortalidad (hazard ratio: 2,68; p=0,0047), con una sensibilidad del 47% y una especificidad del 78%. Este exceso de mortalidad de los pacientes desapareció al ajustar para gravedad mediante análisis de Cox (hazard ratio ajustado de 1,07; p=0,8665). Conclusiones: En pacientes críticos con sepsis, el aumento de los niveles de sTREM-1 a lo largo de los 3 primeros días de evolución se asocia con un exceso de mortalidad, que se explica por la mayor gravedad inicial de estos pacientes. La capacidad discriminativa de este hallazgo es insuficiente para ser útil en la clínica (AU)
Objective: To evaluate the association between plasma levels of soluble Triggering Receptor Expressed on Myeloid Cells-1 (sTREM-1) and mortality of patients with sepsis. Design: Prospective cohort study. Setting: Two general Intensive Care Units. Patients: Patients with sepsis in whom sTREM-1 plasma levels were determined daily in the first 3 days of their presentation. Variables of interest: Mortality at 28 days. Results: We analyzed 121 patients (23% severe sepsis, 44% septic shock, 33% non-severe sepsis). Mortality at 28 days was 24.8%. The initial sTREM-1 levels were slightly higher in nonsurvivors than in survivors (median 366.9 versus 266.5pg/ml, p=0.2668). An increase in sTREM-1 levels higher than 90pg/ml within the first 3 days (delta-TREM) was associated with an excess of mortality (hazard ratio [HR] 2.68, p=0.0047), with a sensitivity of 47% and a specificity of 78%. This excess of mortality disappeared after adjusting for severity by Cox analysis (adjusted HR 1.07, p=0.8665). Conclusions: The increase in the levels of sTREM-1 during the first 3 days of evolution is associated with an excess of mortality in critically ill patients with sepsis. This is explained by the greater initial severity of these patients. The discriminative capacity of this finding is insufficient to be clinically useful (AU)

OBJECTIVE: To evaluate glycoprotein IIb/IIIa inhibitors (GPIIb/IIIa inhibitors) effectiveness and safety in patients with non-ST segment elevation acute coronary syndrome (NSTEACS) or stable coronary disease referred for percutaneous coronary revascularization pre-treated with aspirin and thienopyridines by means of a systematic review. SOURCE OF DATA: Electronic search using Medline, Embase, Pascal, Cochrane Library and ISI Proceedings and manual review of the articles found. STUDY SELECTION: We included randomized controlled trials that assessed the clinical efficacy (risk of death or infarction) and safety (bleeding and thrombocytopenia) of GPIIb/IIIa inhibitors in patients pretreated with thienopyridines. DATA EXTRACTION: Data were obtained by duplicate. RESULTS: Nine randomized controlled trials (8,604 patients) were included. Addition of GPIIb/ IIIa inhibitors reduced the risk of death or myo-cardial infarction at 30 days in those trials that included patients with NSTEACS (RR 0.67; 95%CI 0.56-0.80) but not in studies that excluded NSTEACS patients (RR 1.07; 95%CI 0.75-1.53) (p test of interaction 0.0175), As a counterpart, GPIIb/ IIIa inhibitors increased the risk of bleeding and thrombocytopenia. CONCLUSIONS: Use of GPIIb/IIIa inhibitors reduces the risk of adverse cardiac events in NSTEACS patients pre-treated with aspirin and thienopyridines but increases the risk of severe bleeding and thrombocytopenia. Its utilization in stable coronary patients does not seem justified.

Objetivo. Evaluar, mediante una revisión sistemática de la literatura, la efectividad y seguridad de los antagonistas IIb/IIIa (AGIIb/IIIa) en pacientes con síndrome coronario agudo sin elevación de ST (SCASEST) o cardiopatía coronaria estable sometidos a revascularización percutánea pretratados con aspirina y tienopiridinas. Fuente de datos. Búsqueda electrónica en Medline a través de PubMed, Embase, Pascal, Cochrane Library e ISI Proceedings y revisión manual de las referencias bibliográficas recuperadas. Selección de estudios. Se incluyeron en la revisión aquellos ensayos clínicos aleatorizados que evaluaban el efecto de los AGIIbIIIa en pacientes pretratados con tienopiridinas que incluían información sobre el riesgo a medio plazo de muerte/infarto y/o hemorragia/trombopenia. Extracción de datos. Los datos se obtuvieron por duplicado. Resultados. Se incluyeron 9 ensayos aleatorizados (8.604 pacientes). El tratamiento con AGIIb/IIIa redujo el riesgo de muerte o infarto a los 30 días en los ensayos que incluían pacientes con SCASEST (RR: 0,67; IC95%: 0,56-0,80), pero no en los ensayos que excluían a dichos pacientes (RR 1,07; IC95% 0,75-1,53) (p test de interacción 0,0175). En contrapartida, la adición de un AGIIb/ IIIa aumentó el riesgo hemorrágico y de trombopenia. Conclusiones. El uso de AGIIb/IIIa en pacientes con SCASEST sometidos a intervencionismo coronario, tratados con aspirina y tienopiridinas, reduce el riesgo de eventos cardiovasculares adversos, aunque aumenta el riesgo de trombopenia y complicaciones hemorrágicas. Su utilización en pacientes coronarios estables no parece justificada
