ABSTRACT

INTRODUCCIÓN: Las infecciones bacterianas en trasplante hepático (TH) son una de las principales causas de morbimortalidad. OBJETIVO: Caracterizar las complicaciones infecciosas bacterianas en el primer mes postrasplante. Pacientes y MÉTODOS: Estudio retrospectivo entre los años 2009-2020. RESULTADOS: 225 pacientes recibieron un TH. 80 (35,5%) desarrollaron al menos un episodio de infección bacteriana en el primer mes postrasplante hepático. Hubo 105 episodios de infección bacteriana con una incidencia de 46,6%. El foco más frecuente fue el abdominal (48,6%) y el microorganismo predominante fue Klebsiella spp. De los 104 aislamientos, el 57,6% presentaron un perfil MDR/XDR. Los pacientes que desarrollaron una complicación infecciosa presentaron menor sobrevida al alta hospitalaria en comparación con los que no la presentaron 87,5 versus 94,5% [OR 4,18 (IC 95%: 1,5-11,6)]. En el análisis multivariado la reintervención quirúrgica precoz [OR 4,286 (IC 95%: 1,911-9,61)], mostró un riesgo significativo de desarrollar una complicación infecciosa bacteriana en el primer mes postrasplante. CONCLUSIONES: Tres de cada 10 pacientes presentaron una infección bacteriana en el primer mes postrasplante con una alta incidencia de bacilos gramnegativos MDR/XDR. Los pacientes que desarrollaron una complicación infecciosa presentaron una menor sobrevida al alta. La reintervención quirúrgica precoz se identificó como un factor predisponente de infección temprana.


BACKGROUND: Bacterial infections are one of the main causes of morbidity and mortality in liver transplant recipients (LT). Aim: To characterize bacterial infectious complications in the first month an after a liver transplant. METHODS: Retrospective analysis of a cohort of liver transplant recipients who presented at least one bacterial infectious complication in the first month after transplant between 2009 and 2020. RESULTS: 225 patients were analyzed. 80 (35.5%) had a least one documented bacterial infection during the first month after transplant. 105 bacterial infections were documented, with an incidence of 46.6%. The most frequent origin was intra-abdominal (48.6%) and the predominant isolated microorganism was Klebsiella spp. Among 104 isolated microorganisms 57.6% showed MDR/XDR profile. Patients who developed a bacterial infectious complication had a shorter overall survival (OS) after discharge from hospital (87.5% vs 94.5%) [OR 4.18 (IC 95%: 1.5-11,6)]. When multivariate analysis of predisposing factors was performed early surgical reoperation was the only variable associated with an increased risk of developing a bacterial complication in the first month [OR 4.286 (IC 95%: 1.911-9.61)]. CONCLUSIONS: Three out of 10 patients developed a bacterial infectious complication during the first month after liver transplant with a high incidence of gram-negative bacillus MDR/XDR. Patients who presented infectious complications had a shorter OS after discharge, and early reoperation was identified as a predisposing factor of early infectious complications.
