Treatment duration for central line-associated infection caused by Enterococcus spp.: a retrospective evaluation of a multicenter cohort

Objective of this study was to assess the appropriate treatment duration for enterococcal central line-associated bloodstream infections (CLABSIs). This observational, retrospective, multicenter study conducted between 2011 and 2019 enrolled all hospitalized patients with monomicrobial enterococcal CLABSI. Those with infective endocarditis and non-survivors at least 7 days from index blood culture (BC) were excluded. Primary endpoint was 30-day mortality. We enrolled 113 patients, of whom 59% were male, median age was 64 (SD ± 15) and median Charlson’s index score 5 (IQR 3–8). Enterococcus faecalis and Enterococcus faecium were found in 51% and 44% of cases, respectively. Median treatment duration was 11 days (IQR 6–17), and 32% of patients (n = 36) received ≤ 7 days. Characteristics of patients receiving more or less than 7 days of treatment were similar. Central line was removed in 82% (n = 93) of cases within a median of 3 days (1–8). At both uni- and multivariate analysis, duration of antibiotic treatment > 7 days was not associated with 30-day mortality [HR 0.41 (95% CI, 0.13–1.24), p = 0.12] even after adjustment with propensity score [HR 0.47 (95% CI 0.17–1.26), p = 0.13]. A 7-day treatment course appears to be safe in non-complicated enterococcal CLABSIs

Suspected acute exacerbation of idiopathic pulmonary fibrosis as an outcome measure in clinical trials

Background: Acute exacerbation of idiopathic pulmonary fibrosis has become an important outcome measure in clinical trials. This study aimed to explore the concept of suspected acute exacerbation as an outcome measure.Methods: Three investigators retrospectively reviewed subjects enrolled in the Sildenafil Trial of Exercise Performance in IPF who experienced a respiratory serious adverse event during the course of the study. Events were classified as definite acute exacerbation, suspected acute exacerbation, or other, according to established criteria.Results: Thirty-five events were identified. Four were classified as definite acute exacerbation, fourteen as suspected acute exacerbation, and seventeen as other. Definite and suspected acute exacerbations were clinically indistinguishable. Both were most common in the winter and spring months and were associated with a high risk of disease progression and short-term mortality.Conclusions: In this study one half of respiratory serious adverse events were attributed to definite or suspected acute exacerbations. Suspected acute exacerbations are clinically indistinguishable from definite acute exacerbations and represent clinically meaningful events. Clinical trialists should consider capturing both definite and suspected acute exacerbations as outcome measures. © 2013 Collard et al.; licensee BioMed Central Ltd
