          Abstract

          RESUMEN Objetivo Evaluar los factores de riesgo para infecciones relacionadas con la asistencia sanitaria causadas por Enterobacteriaceaeproductoras de carbapenemas. Método Este es un estudio retrospectivo de casos y controles que consistió en una muestra de 82 pacientes infectados y 164 controles, totalizando 246 pacientes. La recopilación de datos se realizó entre enero y mayo de 2017 mediante la búsqueda en el Sistema Automatizado de Control de Infecciones Hospitalarias y en los registros electrónicos de pacientes. Resultados Pacientes previamente colonizados con microorganismos gramnegativos (OR: 10.7, 95% CI: 2-60, p=0.007), con cáncer (OR: 20.8, 95% CI: 4-120, p<0.001), utilizando una catéter de doble luz (OR: 30.5, 95% CI: 2-382, p=0.008), con lesión por presión (OR: 136.2, 95% CI: 11- 1623, p<0.001) y permanecer en la Unidad de Cuidados Intensivos (OR: 1.4, 95% CI: 1.2-1.6, p <0.001) fueron más propensos a desarrollar infecciones causadas por Enterobacteriaceaeproductoras de carbapenemas que el grupo control. El área bajo la curva ROC mostró un buen rendimiento general (0,99; IC 95%: 0,992-0,998) del modelo de regresión logística final. Conclusión La colonización previa, el cáncer, el uso de catéteres de doble luz, la lesión por presión y la estadía en la UCI fueron factores de riesgo muy importantes para la adquisición de infecciones en el entorno hospitalario.

A área sob a curva ROC apresentou um bom desempenho geral do modelo final de regressão logística (0,99, IC95%: 0,992-0,998). Conclusão Colonização prévia, câncer, uso de cateter de duplo lúmen, lesão por pressão e permanência na UTI foram fatores de risco muito importantes para a aquisição de infecções no ambiente hospitalar.

          ABSTRACT Objective To evaluate the risk factors for healthcare-associated infections caused by Klebsiella pneumoniaecarbapenemase producing Enterobacteriaceae. Method This is a retrospective case-control study that consisted of a sample of 82 infected patients and 164 controls, totaling 246 patients. Data collection was performed between January and May 2017 through search in the Automated Hospital Infection Control System and in the electronic patient records. Results Patients previously colonized with gram-negative microorganisms (OR: 10.7, 95% CI: 2-60, p=0.007), with cancer (OR: 20.8, 95% CI: 4-120, p<0.001), using a double lumen catheter (OR: 30.5, 95% CI: 2-382, p=0.008), with pressure injury (OR: 136.2, 95% CI: 11- 1623, p<0.001) and Intensive Care Unit stay (OR: 1.4, 95% CI: 1.2-1.6, p <0.001) had a greater chance of developing Healthcare-associated Infections caused by KPC-producing Enterobacteriaceaethan the control group. The area under the ROC curve showed a good overall performance (0.99, 95% CI: 0.992-0.998) of the final logistic regression model. Conclusion Previous colonization, cancer, double lumen catheter use, pressure injury and ICU stay were very important risk factors for the acquisition of infections in the hospital environment.

          Incidence, risk factors, and outcomes of Klebsiella pneumoniae bacteremia.

          Although Klebsiella pneumoniae is the second most common cause of Gram-negative bloodstream infections, its epidemiology has not been defined in a nonselected population. We sought to describe the incidence of, risk factors for, and outcomes associated with K. pneumoniae bacteremia. Population-based surveillance for K. pneumoniae bacteremia was conducted in the Calgary Health Region (population 1.2 million) from 2000 to 2007. A total of 640 episodes of K. pneumoniae bacteremia were identified for an overall annual population incidence of 7.1 per 100,000; 174 (27%) were nosocomial, 276 (43%) were healthcare-associated community onset, and 190 (30%) were community acquired. Elderly patients and men were at highest risk for K. pneumoniae bacteremia. Dialysis, solid-organ transplantation, chronic liver disease, and cancer were the most important risk factors for acquiring K. pneumoniae bacteremia. Rates of resistance to trimethoprim/sulfamethoxazole increased significantly during 2000 to 2007. The case fatality rate was 20%, and the annual population mortality rate was 1.3 per 100,000. Increasing age, nosocomial acquisition, non-urinary and non-biliary focus of infection, and several comorbid illnesses were independently associated with an increased risk of death. This is the first population-based study to document the major burden of illness associated with K. pneumoniae bacteremia and identifies groups at increased risk of acquiring and dying of these infections.

            Risk factors for bloodstream infections due to colistin-resistant KPC-producing Klebsiella pneumoniae: results from a multicenter case-control-control study.

            The increasing prevalence of colistin resistance (ColR) Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae (Kp) is a matter of concern because of its unfavourable impact on mortality of KPC-Kp bloodstream infections (BSI) and the shortage of alternative therapeutic options. A matched case-control-control analysis was conducted. The primary study end point was to assess risk factors for ColR KPC-Kp BSI. The secondary end point was to describe mortality and clinical characteristics of these infections. To assess risk factors for ColR, 142 patients with ColR KPC-Kp BSI were compared to two controls groups: 284 controls without infections caused by KPC-Kp (control group A) and 284 controls with colistin-susceptible (ColS) KPC-Kp BSI (control group B). In the first multivariate analysis (cases vs. group A), previous colistin therapy, previous KPC-Kp colonization, ≥3 previous hospitalizations, Charlson score ≥3 and neutropenia were found to be associated with the development of ColR KPC-Kp BSI. In the second multivariate analysis (cases vs. group B), only previous colistin therapy, previous KPC-Kp colonization and Charlson score ≥3 were associated with ColR. Overall, ColR among KPC-Kp blood isolates increased more than threefold during the 4.5-year study period, and 30-day mortality of ColR KPC-Kp BSI was as high as 51%. Strict rules for the use of colistin are mandatory to staunch the dissemination of ColR in KPC-Kp-endemic hospitals.

              Colonization of liver transplant recipients with KPC-producing Klebsiella pneumoniae is associated with high infection rates and excess mortality: a case-control analysis.

              From mid-2010 to early 2013 there was a large single-center (Leipzig University Hospital, Germany) outbreak of Klebsiella pneumoniae carbapenemase (KPC) type 2 producing K. pneumoniae (KPC-2-KP) involving a total of 103 patients. The aim of this study was to compare KPC-positive liver transplant recipients (LTR) and KPC-negative controls to determine both the relative risk of infection following colonization with KPC-2-KP and the case fatality rate associated with KPC-2-KP.
