Abstract
Purpose

A comparison is made of epidemiological variables (demographic and clinical characteristics) and outcomes in patients with hospital-acquired pneumonia (HAP) or ventilator- associated pneumonia (VAP) caused by methicillin-susceptible and methicillin-resistant Staphylococcus aureus (MSSA and MRSA) in the Latin American VAP (LATINVAP) vs. the European Union VAP (EUVAP) cohorts of patients admitted to intensive care units (ICUs).

Methods

The EUVAP project was a prospective, multicenter observational study reporting 827 patients with HAP/VAP in 27 ICUs from 9 European countries. The LATINVAP project was a multicenter prospective observational study, with an identical design, performed in 17 ICUs from 4 Latin American countries involving 99 patients who developed HAP/VAP. Episodes of VAP/HAP caused by S. aureus, MSSA, and MRSA were compared in both cohorts.

Results

Forty-five patients had S. aureus HAP/VAP in the EUVAP cohort vs. 11 patients in the LATINVAP cohort. More patients had MRSA in the LATINVAP study than in the EUVAP (45% vs. 33%). ICU mortality among patients with MSSA HAP/VAP in EUVAP was 10% vs. 50% for LATINVAP (OR = 9.75, p = 0.01). Fifteen patients in the EUVAP cohort developed MRSA HAP/VAP as opposed to 5 in LATINVAP. In the EUVAP study there was an ICU mortality rate of 33.3%. In the LATINVAP cohort, the ICU mortality rate was 60% (OR for death = 3.0; 95%CI 0.24---44.7).

Conclusion

MRSA pneumonia was associated with poorer outcomes in comparison with MSSA. Our study suggests significant variability among European and Latin American ICU practices that may influence clinical outcomes. Furthermore, patients with pneumonia in Latin America have different outcomes.

Resumen
Objetivo

comparar las variables epidemiológicas (características demográficas y clínicas) y los efectos en pacientes con neumonía intrahospitalaria (NIH) o neumonía asociada a la ventilación (NAV) causada por Staphylococcus aureus susceptible a la meticilina (SASM) y resistente a la meticilina (SARM) en las cohortes LATINVAP y EUVAP de pacientes admitidos en unidades de cuidados intensivos (UCI).

Métodos

El proyecto EUVAP fue un estudio prospectivo, multicéntrico y observacional sobre 827 pacientes con NIH/NAV de 27 UCI de 9 países europeos. El proyecto LATINVAP fue un estudio pospectivo, multicéntrico y observacional de idéntico disen¿o que se llevó a cabo en 17 UCI de 4 países latinoamericanos y en el que se evaluaron 99 pacientes que habían desarrollado HAP/VAP. Se compararon entre las cohortes los episodios de VAP/HAP causados por S. aureus (SASM y SARM).

Resultados

Cuarenta y cinco pacientes presentaron NIH/NAV por S. aureus en la cohorte EUVAP frente a 11 pacientes en la cohorte LATINVAP. El número de pacientes con SARM en el estudio LATINVAP fue superior al del estudio EUVAP (45% frente al 33%). La mortalidad en la UCI entre los pacientes con NIH/NAV por SASM del estudio EUVAP fue del 10% frente al 50% en el caso del estudio LATINVAP (OR = 9,75, p = 0,01). Quince pacientes de la cohorte EUVAP desarrollaron NIH/NAV por SARM frente a 5 de la cohorte LATINVAP. En el estudio EUVAP se registró una tasa de mortalidad del 33,3%. En la cohorte LATINVAP la tasa de mortalidad en la UCI fue del 60% (OR de muerte = 3,0; IC del 95% de 0,24 a 44,7).

Conclusiones

La neumonía por SARM se asoció a unos peores resultados en comparación con la neumonía por SASM. Nuestro estudio sugiere una variabilidad importante entre las prácticas de las UCI europeas y latinoamericanas que podría influir sobre los resulta- dos clínicos. Además, los pacientes con neumonía de Latinoamérica presentaron resultados diferentes.
