RESUMO

Objetivo. Describir la efectividad y tolerabilidad delajuste de dosis de meropenem en el tratamiento empíricode infecciones nosocomiales en pacientes críticos ingresadosen Servicios de Medicina Intensiva (SMI).Método. Estudio prospectivo, observacional y multicéntricode pacientes ingresados en 17 SMI con infecciones nosocomialesy tratamiento inicial con meropenem a dosis de1 g cada 8 h. Se ajustó la dosis inicial a 0,5 g cada 8 h cuandocumplían las siguientes condiciones: a) evolución clínicafavorable y b) un aislamiento microbiológico sensible a meropenemo ausencia de microorganismos en los cultivos realizados.Resultados. Se incluyeron 92 pacientes en los que seajustó la dosis de meropenem a 0,5 g cada 8 h. La infeccióntratada más frecuentemente fue la neumonía relacionadacon ventilación mecánica, seguido de las bacteriemias. Losestudios microbiológicos fueron positivos en 53 pacientesen los que predominaron bacterias grampositivas (53,7 %),en especial Staphylococcus aureus sensible a la meticilina,seguido de bacterias gramnegativas (42,7%).En 18 casos los pacientes no fueron evaluables al finaldel tratamiento. De los 74 casos evaluables, 67 (90,5%) presentaronuna evolución favorable (curación: 54 pacientes;mejoría: 13). En 50 de los 53 casos evaluables por Microbiologíase logró la erradicación o supuesta erradicación de losmicroorganismos iniciales y en 3 persistió el patógeno inicial:Acinetobacter baumannii (2 casos) y Pseudomonasaeruginosa (1 caso). Se detectó la aparición de nuevos microorganismosdurante el tratamiento en tres ocasiones: A. baumannii(2 casos) y 1 de S. aureus resistente a la meticilina.Aparecieron efectos adversos en 3 pacientes (4%), ninguno valorado como grave, que no precisaron la retirada del tratamiento.Fallecieron 25 (27,2%) pacientes, 3 de ellos en relacióncon la infección (AU)


Objective. To describe the effectiveness and tolerabilityof the dose adjustment of meropenem in empiricaltreatment of nosocomial infections in critically-ill patientsadmitted to intensive care medicine services.Methods. Prospective, observational and multicenterstudy in patients admitted to 17 intensive care medicineservices with nosocomial infection, who were initiallytreated with meropenem, 1 g every 8 h, were eligible.The initial dose was adjusted to 0.5 g every 8 h if therewere: a) a favorable clinical course, and b) microbiologicalisolation of meropenem-susceptible pathogens or absenceof pathogens in cultures.Results. Ninety-two patients in whom meropenemdoses were adjusted to 0.5 g every 8 h were included.Ventilator-associated pneumonia followed by bacteremiawas the most frequently treated infections. Microbiologicalstudies were positive in 53 patients, with apredominance of gram-positive bacteria (53.7%), especiallymethicillin-susceptible Staphylococcus aureus,followed by gram-negative bacteria (42.7 %). A total of18 patients were not evaluable at the end of treatmentSixty-seven (90.5 %) of the 74 evaluable patients had afavorable clinical course (54 patients cured and 13 improved).In 50 out of 53 microbiologically evaluable cases,eradication or apparent eradication of initial microorganismswas achieved. In 3 cases, the initial pathogenpersisted: Acinetobacter baumannii (2 cases) and Pseudomonasaeruginosa (1 case). On three occasions, new pathogensdeveloped during treatment: A. baumannii (2cases) and methicillin-resistant S. aureus (1 case). Adverseevents occurred in 3 patients (4%), none of whichwas considered severe, and withdrawal of meropenemwas not necessary. A total of 25 (27.2 %) patients died,three of them in relation to the infectious process(AU)

RESUMO

INTRODUCTION: Acute hepatic failure (AHF) is an uncommon entity but with high mortality. Liver transplantation has improved prognosis but is an aggressive treatment with high risk. Currently, there are no accurate criteria to differentiate between irreversible AHF and the possibility of hepatic regeneration. The aim of this study is to review the clinical characteristics indicating transplantation and the outcome of AHF in patients at our institution. PATIENTS AND METHOD: Descriptive and retrospective study of cases of AHF at our institution in the last 3 years. RESULTS: Eleven patients were studied. Mortality was lower in transplant recipients (23%; 2 out of 8) than in non-transplanted patients (67%; 2 out 3). Hepatic regeneration occurred in one patient. Overall mortality was 36% with a perioperative mortality of 13%. CONCLUSION: The indication of hepatic transplantation in patients with a poor prognosis, early stage acute liver failure, and a low grade of encephalopathy, and prior to the development of multiorgan failure could improve the results of transplantation and reduce perioperative mortality.

RESUMO

INTRODUCCIÓN: El fallo hepático agudo (FHA) es una entidad infrecuente pero con una alta mortalidad. La instauración del trasplante hepático, que es un tratamiento radical y de riesgo, ha mejorado el pronóstico. No disponemos actualmente de criterios certeros que diferencien la posibilidad de regeneración hepática del FHA irreversible. El objetivo de nuestro estudio ha sido revisar las características clínicas determinantes de la indicación del trasplante y la evolución de los pacientes con FHA en nuestro medio. PACIENTES Y MÉTODO: Estudio descriptivo retrospectivo delos casos de FHA ingresados en nuestra unidad en 3 años. RESULTADOS: Se recogieron 11 casos. Se observó una menor mortalidad en los pacientes trasplantados (23%; 2 de 8) que en los no intervenidos (67%; 2 de 3). Un solo caso presentó regeneración hepática. La mortalidad global fue del 36%con una mortalidad perioperatoria del 13%.CONCLUSIÓN: La indicación de trasplante hepático en los pacientes con criterios de mal pronóstico en una fase temprana, con un bajo grado de encefalopatía y previo al desarrollo de fracaso multiorgánico, podría mejorar el resultado del trasplante y disminuir la mortalidad perioperatoria
