    ABSTRACT: The present article is an update of the literature on endocarditis. A multidisciplinary group of Spanish physicians with an interest in cardiac infections selected the most important papers produced lately in the field. Two of the members of the group discussed the content of each of the selected papers, with a critical review by others members of the panel. After a review of the state of the art papers from the fields of epidemiology, new causative microorganisms (bacterial and fungal), clinical findings including those in special patients, laboratory diagnosis, prognostic factors, nosocomial endocarditis, prophylaxis, new drugs and guidelines for antibiotic treatment were discussed by the group.

    ABSTRACT: Introduction: Catheter-related bloodstream infection (CR-BSI) is a cause of morbidity and mortality in intensive care units, and the optimal approach for preventing these infections is not well defined. Comparison of CR-BSI rates with those provided by programs such as the National Nosocomial Infection Surveillance System (NNISS) from the USA and the Spanish National Nosocomial Infection Surveillance Study (ENVIN), enable determination of the need to implement control measures. In 2000, we found that the CR-BSI rates in UCIs of our hospital were much higher than the data reported by ENVIN. Objective: To assess the impact of implementing a protocol for proper use of intravascular catheters on CR-BSI rates in the intensive care unit (ICU) of a tertiary hospital. Methods: Prospective study of patients admitted to the ICUs of a tertiary hospital in the months of May and June, from 2000 to 2004. In 2001, a CR-BSI prevention program including aspects related to catheter insertion and maintenance in ICU patients was implemented. We calculated infection rates per 1000 days of catheter use in all the 2-month periods studied, and compared the 2000 and 2004 results by analysis of the odds ratios and confidence intervals.

We calculated infection rates per 1000 days of catheter use in all the 2-month periods studied, and compared the 2000 and 2004 results by analysis of the odds ratios and confidence intervals. A total of 923 patients were included. Mean age was 58.7 years (SD: 15.4), mean ICU stay was 11.6 days (SD: 11.4), mean SAPSII was 28.2 (SD: 15.9), and mortality was 20.5%. There was a significant reduction in CR-BSI rates from 13.3 episodes per 1000 days of catheter use in the first period to 3.21 in the last period (OR=3.53, 95% CI: 2.36-5.31). Application of a prevention program for CR-BSI and a system for monitoring BSI rates led to a significant, sustained reduction in these infections.

    ABSTRACT: To describe the incidence and clinical characteristics of imipenem-resistant (IR) Pseudomonas aeruginosa bacteraemia. We performed a retrospective study including all episodes of IR P. aeruginosa bacteraemia seen from January 2003 to December 2005 in a tertiary teaching hospital. There were 108 episodes of IR P. aeruginosa bacteraemia, which represented an incidence of 0.14 episodes per 1000 patient-days in 2003 and 0.11 episodes per 1000 patient-days in 2005. 83 of the episodes (77%) were nosocomially acquired. Most of patients had at least one underlying disease and had previously received antimicrobial treatment. The most frequent source was the urinary tract (31%), followed by unknown origin (22%). A total of 23 (21%) episodes were polymicrobial and 51 (47%) were caused by multidrug-resistant strains. The independent risk factors for mortality from IR P. aeruginosa bloodstream infection were a high-risk source of the bacteraemia (OR: 4.6; 95% CI 1.7-12.4; p=0.01), and presentation with severe sepsis (OR: 2.8; 95% CI 1-7.8; p=0.05). Our study shows that the rates of IR P. aeruginosa bacteraemia remained stable throughout the study period. The source of bacteraemia and the clinical presentation with severe sepsis were the main determinants of the prognosis.

    ABSTRACT: Bacteremia and endocarditis due to methicillin-resistant Staphylococcus aureus (MRSA) are prevalent and clinically important. The rise in MRSA bacteremia and endocarditis is related with the increasing use of venous catheters and other vascular procedures. Glycopeptides have been the reference drugs for treating these infections. Unfortunately their activity is not completely satisfactory, particularly against MRSA strains with MICs > 1 microg/mL. The development of new antibiotics, such as linezolid and daptomycin, and the promise of future compounds (dalvabancin, ceftobiprole and telavancin) may change the expectatives in this field.The principal aim of this consensus document was to formulate several recommendations to improve the outcome of MRSA bacteremia and endocarditis, based on the latest reported scientific evidence. This document specifically analyzes the approach for three clinical situations: venous catheter-related bacteremia, persistent bacteremia, and infective endocarditis due to MRSA.

    ABSTRACT: El presente artículo recoge una actualización bibliográfica de patógenos bacterianos. Dado el interés científico y la importancia que tienen para la salud pública las infecciones producidas por patógenos bacterianos con nuevos mecanismos de virulencia y/o nuevos mecanismos de resistencia a los antimicrobianos, un grupo multidisciplinario de microbiólogos y clínicos españoles, con experiencia en enfermedades infecciosas, organizó una reunión en la que se revisaron los artículos más importantes en este campo, publicados en 2006. El contenido de cada uno de los artículos seleccionados fue expuesto y discutido por uno de los miembros del grupo. Este artículo revisa algunas de las enfermedades infecciosas bacterianas que suponen hoy en día algunos de los principales retos para la salud pública e incluye las infecciones producidas por Staphylococcus aureus resistente a meticilina de adquisición comunitaria, las producidas por variantes de colonia pequeña de S. aureus, las relacionadas con estafilococos coagulasa negativa multirresistentes, la infección neumocócica, la listeriosis humana, la infección meningocócica, la tos ferina, las infecciones por Haemophilus influenzae, la diseminación de las bacterias productoras de BLEE, y las infecciones por bacilos gramnegativos no fermentadores. Tras la revisión de la situación actual, se discuten y comentan diferentes artículos relacionados con estos aspectos.

    ABSTRACT: To investigate an increase in the number of Salmonella enteritidis isolates detected in a large hospital to ascertain whether it was due to a nosocomial source, to identify the mechanisms of transmission, and to institute effective control measures to prevent future episodes. Observational study, survey of all microbiological samples positive for S. enteritidis detected in the hospital, outbreak investigation, and review of the literature. A tertiary-care teaching hospital for adults in Barcelona, Spain. During a 7-month period from May to November 1998, we identified 22 inpatients with S. enteritidis infection for whom nosocomial acquisition was strongly suspected. The attack rate was 0.138 per 1,000 patient-days. All affected patients were immunosuppressed and overall mortality was 41% (9 of 22). A sample of a meal cooked in the kitchen was culture positive for S. enteritidis. All isolates shared the same antibiotic susceptibility pattern and all except one shared the same pulsed-field gel electrophoresis (PFGE) pattern, but PFGE could not differentiate between outbreak-related and control strains. After compliance with kitchen hygiene procedures was emphasized and cleansing was intensified, no more cases were detected. Apparently, sporadic cases of S. enteritidis may be part of an outbreak with a low attack rate. A small but persistent inoculum affecting only individuals with special predisposition for Salmonella infection might account for this. Suspicion should be raised in hospitals and institutions with a highly susceptible population.

    ABSTRACT: La sepsis grave y el shock séptico son causas frecuentes de fallecimiento en las unidades de cuidados intensivos (UCI). La incidencia de sepsis se ha incrementado durante los 2 últimos decenios y se considera que lo va a seguir haciendo durante los próximos años. A pesar de que actualmente poseemos mucha más información acerca de las complejas alteraciones fisiopatológicas que tienen lugar en la sepsis grave y en el shock séptico, los pacientes con sepsis siguen presentando un elevado riesgo de muerte. Sin embargo, durante los últimos años la introducción de nuevas estrategias terapéuticas ha mejorado significativamente el pronóstico de estos pacientes. En este artículo se revisan nueve estudios de gran envergadura publicados en 2004 y 2005: en dos de ellos se abordan las tasas de incidencia, la distribución de los patógenos y las tendencias en la resistencia frente a los antibióticos en los pacientes con sepsis atendidos en la UCI; en otros dos artículos se exponen diversos aspectos seleccionados del tratamiento antibiótico, la utilidad del tratamiento de combinación en los cuadros de sepsis que presentan los pacientes inmunocompetentes y el impacto del tratamiento empírico en los cuadros de sepsis causados por Pseudomonas aeruginosa; en otras dos publicaciones se consideran la utilidad de la evaluación del riesgo en el tratamiento de la sepsis y la importancia de una evaluación clínica dinámica en los pacientes con infección y en situación clínica crítica. En los tres estudios restantes se analiza el tratamiento complementario en la sepsis grave: el efecto de un protocolo de control intensivo de la glucemia sobre la evolución de los pacientes en situación clínica crítica; la evaluación de la insuficiencia suprarrenal relativa y de la variabilidad de las concentraciones plasmáticas de cortisol durante un período de 24 horas, y el uso de drotrecogina alfa (activada) en los adultos con sepsis grave y riesgo bajo de muerte.
