Moxifloxacin monotherapy versus combination therapy in patients with severe community-acquired pneumonia evoked ARDS.
Abstract
BACKGROUND: We tested the hypothesis that moxifloxacin monotherapy is equally effective and safe as a betalactam antibiotic based combination therapy in patients with acute respiratory distress syndrome (ARDS) evoked by severe community acquired pneumonia (CAP).
METHODS: In a retrospective chart review study of 229 patients with adult respiratory distress syndrome (ARDS) admitted to our intensive care unit between 2001 and 2011, 169 well-characterized patients were identified to suffer from severe CAP. Patients were treated with moxifloxacin alone, moxifloxacin in combination with ß-lactam antibiotics, or with another antibiotic regimen based on ß-lactam antibiotics, at the discretion of the admitting attending physician. The primary endpoint was 30-day survival. To assess potential drug-induced liver injury, we also analyzed biomarkers of liver cell integrity.
RESULTS: 30-day survival (69% overall) did not differ (p = 0.89) between moxifloxacin monotherapy (n = 42), moxifloxacin combination therapy (n = 44), and other antibiotic treatments (n = 83). We found significantly greater maximum activity of aspartate transaminase (p = 0.048), alanine aminotransferase (p = 0.003), and direct bilirubin concentration (p = 0.01) in the moxifloxacin treated groups over the first 10-20 days. However, these in-between group differences faded over time, and no differences remained during the last 10 days of observation.
CONCLUSIONS: In CAP evoked ARDS, moxifloxacin monotherapy and…
