PurposeIn this multicentre, retrospective, matched cohort study we aimed to evaluate the outcomes of neutropenic fever cases that were treated with daptomycin or a glycopeptide (vancomycin or teicoplanin).MethodsData and outcomes of adult (aged>18-years old) patients with neutropenic fever [(1) without clinical and radiological evidence of pneumonia, (2) who were treated with daptomycin or a glycopeptide (teicoplanin or vancomycin) for any reason and for at least 72 h] were extracted from the hospital databases. Matching was performed with all of the three following criteria: (1) underlying disease, (2) reason for starting daptomycin or glycopeptide (microbiologic evidence vs. microbiologic evidence, clinical infection vs. clinical infection and empirical therapy vs. empirical therapy) and (3) neutropenic status.ResultsOverall 128 patients [(69/123) (56.1%) in the daptomycin cohort (D) and 59/123 (48%) in the glycopeptide cohort (G)] had a resolution of fever at the end of 72h antibiotic treatment (p=0.25). There was no significant difference in cured, improved and (cured+improved) rates between (D) and (G) cohorts as well as fever of unknown origin cases or microbiologically confirmed infections or clinically defined infections subgroups (p>0.05). There was also no significant difference (p>0.05), in terms of persistent response in the (D) versus (G) cohorts,ConclusionsThese findings suggest that although not better, daptomycin efficacy is comparable to vancomycin if used as empiric therapy in the treatment of adult febrile neutropenia. We conclude that daptomycin may be used at least as a salvage therapy alternative to glycopeptides in the treatment of adult febrile neutropenia cases. A large, randomized-controlled trial may further consolidate the evidence related to this question.

Sepsis is a severe clinical syndrome owing to its high mortality. Quick Sequential Organ Failure Assessment (qSOFA) score has been proposed for the prediction of fatal outcomes in sepsis syndrome in emergency departments. Due to the low predictive performance of the qSOFA score, we propose a modification to the score by adding age. We conducted a multicenter, retrospective cohort study among regional referral centers from various regions of the country. Participants recruited data of patients admitted to emergency departments and obtained a diagnosis of sepsis syndrome. Crude in-hospital mortality was the primary endpoint. A generalized mixed-effects model with random intercepts produced estimates for adverse outcomes. Model-based recursive partitioning demonstrated the effects and thresholds of significant covariates. Scores were internally validated. The H measure compared performances of scores. A total of 580 patients from 22 centers were included for further analysis. Stages of sepsis, age, time to antibiotics, and administration of carbapenem for empirical treatment were entered the final model. Among these, severe sepsis (OR, 4.40; CIs, 2.35-8.21), septic shock (OR, 8.78; CIs, 4.37-17.66), age (OR, 1.03; CIs, 1.02-1.05) and time to antibiotics (OR, 1.05; CIs, 1.01-1.10) were significantly associated with fatal outcomes. A decision tree demonstrated the thresholds for age. We modified the quick Sequential Organ Failure Assessment (mod-qSOFA) score by adding age (> 50 years old = one point) and compared this to the conventional score. H-measures for qSOFA and mod-qSOFA were found to be 0.11 and 0.14, respectively, whereas AUCs of both scores were 0.64. We propose the use of the modified qSOFA score for early risk assessment among sepsis patients for improved triage and management of this fatal syndrome.
Variables Determining Mortality in Patients With Acinetobacter Baumannii Meningitis/Ventriculitis Treated With Intrathecal Colistin

Aim: To examine the variables associated with mortality in patients with Acinetobacter baumannii-related central nervous system infections treated with intrathecal colistin. Materials and methods: This multi-centre retrospective case control study included patients from 11 centres in Turkey, as well as cases found during a literature review. Only patients with CNS infections caused by multidrug-resistant or extensively drug-resistant Acinetobacter baumannii treated with intrathecal colistin were included in this study. The variables associated with mortality were determined by dividing the patients into groups who died or survived during hospitalisation, and who died or survived from Acinetobacter meningitis. Results: Among the 77 cases enrolled in the study, 35 were found through a literature review and 42 were cases from our centres. Forty-four cases (57.1%) were male and the median age was 48 years (range: 20-78 years). Thirty-seven patients (48%) died during hospitalisation. The variables associated with increased all-cause mortality during hospitalisation included old age (odds ratio, 1.035; 95% confidence interval (Cl), 1.004-1.067; p = 0.026) and failure to provide cerebrospinal fluid sterilisation (odds ratio, 0.264; 95% confidence interval, 0.097-0.724; p = 0.01). There is a trend (P=0.062) towards higher mortality with using of meropenem during meningitis treatment. Fifteen cases (19%) died from meningitis. There were no significant predictors of meningitis-related mortality. Conclusions: The mortality rate for central nervous system infections caused by multidrug-resistant or extensively drug-resistant Acinetobacter baumannii is high. Old age and failure to provide CSF sterilisation are associated with increased mortality during hospitalisation. (C) 2016 Published by Elsevier B.V.
