Comparative StudyComparative roles of moxifloxacin and levofloxacin in the treatment of pulmonary multidrug-resistant tuberculosis: a retrospective study.
This study compared the efficacy of moxifloxacin and levofloxacin in the treatment of multidrug-resistant tuberculosis (MDR-TB) in Shanghai, China. A retrospective analysis of 158 patients with MDR-TB receiving either moxifloxacin- or levofloxacin-containing regimens was performed. Clinical data from patients were subjected to univariate analysis, stratification and multiple logistic regression to compare the roles of moxifloxacin and levofloxacin in multidrug regimens. ⋯ No demographic, clinical, bacteriological or treatment characteristics were independent predictors of favourable outcome. Fourteen patients from the moxifloxacin group and twelve patients from the levofloxacin group had bacteriological relapse after treatment cessation. In conclusion, compared with levofloxacin, moxifloxacin did not show superior efficacy when incorporated into multidrug regimens used for the treatment of MDR-TB.

Pharmacokinetics of meropenem and piperacillin in critically ill patients with indwelling surgical drains.
Meropenem and piperacillin are two commonly prescribed antibiotics in critically ill surgical patients. To date, the pharmacokinetics of these antibiotics in the presence of indwelling abdominal surgical drains is poorly defined. This was a prospective pharmacokinetic study of meropenem and piperacillin. ⋯ A linear correlation was present between the percentage of antibiotic cleared through the drain and the volume of surgical drain fluid output for meropenem (r(2) = 0.89; P = 0.05) and piperacillin (r(2) = 0.63; P = 0.20). Meropenem and piperacillin have altered pharmacokinetics in critically ill patients with indwelling surgical drains. We propose that only when very high drain fluid output is present (>1000 mL/day) would an additional dose of antibiotic be necessary.
