Abstract
in English, Spanish

Although the transfusionofblood products is common practice, its effects on the immune system have not been adequately studied. A prospective cohort study was conducted in critically ill children followed up until their death, transfer or discharge to establish an association between red blood cell transfusions (RBCTs) and nosocomial infections. A nosocomial infection was considered to be post-transfusional if it occurred within 14 days after RBCT. A total of 162 children were included in the study, 35 (21.6%) had a nosocomial infection, and 49 (30.2%) received a RBCT. Among those with a nosocomial infection, a RBCT was more common (48.5% versus 14.9%, OR: 5.4, 95% CI: 2.412.6, p 〈 0.0001) and mortality rate was higher (45.7% versus 10.2%, OR: 7.4, 95% CI: 3.1-18.2, p 〈 0.0001). The binary logistic regression showed that RBCT was independently associated with nosocomial infections (OR: 4.2, 95% CI: 2.1-20.2, p = 0.049).

Conclusion: RBCT was associated with increased risk for nosocomial infections.

Aunque la transfusión de hemoderivados es una práctica común, los efectos sobre el sistema inmune no han sido bien estudiados. Para determinar la asociación entre transfusión de glóbulos rojos (TGR) e infecciones nosocomiales, se realizó un estudio de cohorte prospectivo con niños críticamente enfermos, seguidos hasta su fallecimiento, transferencia o egreso. Las infecciones nosocomiales se consideraron postransfusionales si ocurrieron dentro de los 14 días después de la TGR. Se incluyeron 162 niños, 35 adquirieron infección nosocomial (21,6%) y 49 recibieron TGR (30,2%). Los niños con infección nosocomial recibieron más frecuentemente TGR (48,5% vs. 14,9%; OR 5,4; IC 95%: 2,4-12,6; p 〈 0,0001) y presentaron mayor mortalidad (45,7% vs. 10,2%; OR 7,4; IC 95%: 3,1-18,2; p 〈 0,0001). En la regresión logística binaria, la TGR se mantuvo asociada independientemente a infección nosocomial (OR 4,2; IC 95%: 2,1-20,2; p = 0,049). Conclusión: La TGR se asoció a un incremento del riesgo de adquirir infecciones nosocomiales.
