Moxifloxacin versus standard therapy in patients with pneumonia hospitalized after failure of preclinical anti-infective treatment.Infection. 2006 Aug; 34(4):190-5.I
The failure rate of primary empirical anti-infective treatment of community-acquired pneumonia is reported to range between 2 and 7%. These patients are subject to a greater risk of intensive medical treatment and a higher mortality rate than patients who respond to primary treatment. We investigated 63 patients in a "real life scenario" who were admitted to the hospital after failure of primary outpatient therapy for community-acquired pneumonia. Thirty-three patients received intravenous standard therapy (betalactam 14, macrolide 3, levofloxacin 6, doxycycline 1, combinations 9 patients) while 30 patients were treated with intravenous moxifloxacin. The oral antibiotic pretreatment that failed most frequently was clarithromycin (n = 25), followed by amoxicillin/clavulanic acid (n = 16), cefixime (n = 10), cefuroxime/axetil (n = 5), doxycycline (3), cefpodoxime, and ciprofloxacin (2 each). There were no differences between the two groups in respect of age, gender, numbers of patients in nursing homes, numbers of patients with different underlying diseases (chronic bronchitis, coronary heart disease, diabetes mellitus, smoking, etc.), severity of pneumonia at the time of admission, numbers of patients requiring intensive care, and lethality. The group that underwent standard therapy experienced failure of the empirical intra-hospital antibiotic therapy more often during therapy [10 (30%) patients vs 2 (6%) in the moxifloxacin group, p = 0.009] and clinical failure of treatment on day 28 after initiation of therapy [7 (21%) patients vs 2 (6%) in the moxifloxacin group, p = 0.003]. In cases of failure of empirical preclinical antibiotic treatment for community-acquired pneumonia, subsequent intrahospital treatment with moxifloxacin is more successful than standard therapy in our study reflecting a "real life scenario".
