Early, Goal-Directed Therapy for Septic Shock — A Patient-Level Meta-Analysis

N Engl J Med  Mar 21, 2017

The PRISM Investigators*

BACKGROUND

After a single-center trial and observational studies suggesting that early, goal-directed therapy (EGDT) reduced mortality from septic shock, three multicenter trials (ProCESS, ARISE, and ProMISe) showed no benefit. This meta-analysis of individual patient data from the three recent trials was designed prospectively to improve statistical power and explore heterogeneity of treatment effect of EGDT.

METHODS

We harmonized entry criteria, intervention protocols, outcomes, resource-use measures, and data collection across the trials and specified all analyses before unblinding. After completion of the trials, we pooled data, excluding the protocol-based standard-therapy group from the ProCESS trial, and resolved residual differences. The primary outcome was 90-day mortality. Secondary outcomes included 1-year survival, organ support, and hospitalization costs. We tested for treatment-by-subgroup interactions for 16 patient characteristics and 6 care-delivery characteristics.

RESULTS

We studied 3723 patients at 138 hospitals in seven countries. Mortality at 90 days was similar for EGDT (462 of 1852 patients [24.9%]) and usual care (475 of 1871 patients [25.4%]); the adjusted odds ratio was 0.97 (95% confidence interval, 0.82 to 1.14; P=0.68). EGDT was associated with greater mean (±SD) use of intensive care (5.3±7.1 vs. 4.9±7.0 days, P=0.04) and cardiovascular support (1.9±3.7 vs. 1.6±2.9 days, P=0.01) than was usual care; other outcomes did not differ significantly, although average costs were higher with EGDT. Subgroup analyses showed no benefit from EGDT for patients with worse shock (higher serum lactate level, combined hypotension and hyperlactatemia, or higher predicted risk of death) or for hospitals with a lower propensity to use vasopressors or fluids during usual resuscitation.

CONCLUSIONS

In this meta-analysis of individual patient data, EGDT did not result in better outcomes than usual care and was associated with higher hospitalization costs across a broad range of patient and hospital characteristics.

Corticosteroids in treating CAP – has the time really come.

Clinical Microbiology and Infection May 2017 V.23 N.5

Whether corticosteroids should be used in the treatment of severe community-acquired pneumonia (CAP) is still a matter of debate.

This question is all the more relevant as pneumonia remains a leading cause of death worldwide.

Severe CAP is associated with an increase in pulmonary and circulatory cytokines, which may be associated with treatment failure, especially in bacteraemic pneumococcal pneumonia.

Thus corticosteroids, which suppress inflammatory reactions and prevent the migration of inflammatory cells to tissues, may be of particular interest in the treatment of such severe pneumonias …

Abstract

OBJECTIVES:

We conducted a systematic review and meta-analysis to summarize the clinical evidence and usage patterns of intravenous fosfomycin from its development to the present time.

METHODS:

PubMed, the Cochrane Library and local journals were searched for relevant studies reporting aggregated data of intravenous fosfomycin use in adults and children, with no restrictions regarding study design. Single case reports were excluded. Data were systematically abstracted for all included studies. Clinical and microbiological efficacy from randomized controlled and comparative observational studies were synthesized using meta-analysis to calculate pooled effect sizes.

RESULTS:

In all, 128 studies on intravenous fosfomycin in 5527 patients were evaluated. Fosfomycin was predominantly used for sepsis/bacteraemia, urinary tract, respiratory tract, bone and joint, and central nervous system infections. No difference in clinical (OR 1.44, 95% CI 0.96-2.15) or microbiological (OR 1.28, 95% CI 0.82-2.01) efficacy between fosfomycin and other antibiotics was observed in comparative trials. The pooled estimate for resistance development during fosfomycin monotherapy was 3.4% (95% CI 1.8%-5.1%). Fosfomycin showed a favourable safety profile, with generally mild adverse events not requiring discontinuation of treatment. Included studies explored intravenous fosfomycin as an anti-staphylococcal agent in monotherapy and combination therapy, whereas studies from 1990 focused on combination therapy (fosfoymcin + β-lactams or aminoglycosides) for challenging infections frequently caused by multidrug-resistant organisms.

CONCLUSION:

Intravenous fosfomycin can play a vital role in the antibiotic armamentarium, given its long history of effective and safe use. However, well-designed randomized controlled trials are still desired.

Abstract

Yersinia enterocolitica infection rarely can cause extra-intestinal infections. We present a case of septic arthritis of the shoulder due to this organism in an elderly man with liver and cardiac disease. We review previously published cases of Y. enterocolitica septic arthritis, and discuss risk factors and management.

Daptomicina es un anti-infeccioso de reciente introducción en Chile, miembro exclusivo de una nueva familia de antimicrobianos conocida como lipopéptidos cíclicos. Tiene un mecanismo de acción único que le confiere un potente efecto bactericida sobre los microorganismos susceptibles. Su especto antimicrobiano comprende cocáceas grampositivas de importancia clínica como Staphylococcus aureus y Enterococcus spp., incluyendo cepas resistentes a antimicrobianos habituales. Está aprobada para el uso clínico en infecciones de piel y tejidos blandos y bacteriemia complicada y no complicada por S. aureus, en adultos. Estudios en curso sugieren que será una alternativa útil en otras infecciones frecuentes como osteomielitis, infecciones asociadas a dispositivos ortopédicos, infecciones asociadas a biopelículas e infecciones en hospederos inmunosuprimidos, en particular en pacientes onco-hematológicos. El principal efecto adverso asociado al uso de daptomicina es la toxicidad muscular, observándose miopatía reversible, la mayoría de las veces asintomática, en aproximadamente 3% de los pacientes que utilizan el fármaco.

Yersinia enterocolitica: patogénesis, virulencia y resistencia a antibióticos

Enferm Infecc Microbiol Clin 2012;30:24-32

Anna Fàbrega, Jordi Vila

Department of Microbiology, Hospital Clínic, School of Medicine, University of Barcelona, Spain

Y. enterocolitica es un grupo heterogéneo de cepas clasificadas en 6 biogrupos y en más de 57 serogrupos O. Las cepas patógenas humanas más frecuentemente aisladas pertenecen a los serogrupos O:3, O:5,27, O:8 y O:9.

La transmisión de la infección es principalmente a través de alimentos o agua contaminados. La etapa esencial de la patogénesis es la colonización del tracto intestinal, donde ocurren la mayoría de los efectos patológicos y manifestaciones clínicas.

La temperatura y la concentración de calcio regulan la expresión de los factores de virulencia que guían al patógeno durante la invasión, supervivencia y diseminación. Normalmente las infecciones gastrointestinales son autolimitadas y no necesitan tratamiento antimicrobiano.

Las fluoroquinolonas y cefalosporinas de tercera generación son los tratamientos más eficaces en casos de enterocolitis en immunodeprimidos, septicemia o infección invasiva, situaciones en las que la mortalidad puede alcanzar el 50%.

Se presenta una revisión de la patogénesis, virulencia y resistencia antimicrobiana.
