Comparison of levofloxacin and cefotaxime combined with ofloxacin for ICU patients with community-acquired pneumonia who do not require vasopressors.

STUDY OBJECTIVES: To evaluate the efficacy and tolerability of levofloxacin (L) as monotherapy in patients with severe community-acquired pneumonia (CAP) in comparison with therapy using a combination of cefotaxime (C) plus ofloxacin (O). DESIGN: Prospective, randomized 1:1, comparative, open, parallel-group study. SETTING: Multinational study with 149 sites. PATIENTS: A total of 398 randomized patients who had been admitted to the ICU with severe CAP without shock, including 308 patients in a modified intent-to-treat population and 271 patients in the per-protocol (PP) population (L group, 139 patients; C + O group, 132 patients). INTERVENTIONS: Therapy with levofloxacin (500 mg IV, q12h) vs therapy with a C + O combination (C, 1g IV, q8h; O, 200 mg IV, q12h) for 10 to 14 days. MEASUREMENTS AND RESULTS: The main end point was the clinical efficacy at the end of treatment (ie, the test-of-cure [TOC] visit). The statistical hypothesis was the noninferiority of L therapy to C + O therapy with a 2.5% alpha risk (unilateral) and a 15% maximum set difference. At the TOC visit, a clinical success was observed in 79.1% of patients (L group) and 79.5% of patients (C + O group) in the PP population (difference, -0.4%; 95% confidence interval [CI], -10.79 to 9.97% without adjustment for simplified acute physiology score [SAPS] II at inclusion; difference, -0.3%; 95% CI, -10.13 to 9.58% with adjustment for SAPS II). A satisfactory bacteriologic response was present in 73.7% of L group patients and 77.5% of C + O group patients, including responses of 75.7% and 70.3%, respectively, in the L group and C + O group in the Streptococcus pneumoniae-documented population. In the safety analysis, 20 patients in the L group (10.3%) and 16 patients in the C + O group (8.0%) experienced at least one adverse event that was considered to be treatment-related. CONCLUSION: L therapy was at least as effective as the combination therapy of C + O in the treatment of a subset of patients with CAP requiring ICU admission. This conclusion cannot be extrapolated to patients requiring mechanical ventilation or vasopressors (ie, those patients in shock).

Pneumomediastinum causing pneumoperitoneum during mechanical ventilation.

The causes of nonsurgical pneumoperitoneum include numerous diseases. We report here a case of nonsurgical pneumoperitoneum caused by benign pneumomediastinum during mechanical ventilation, and we discuss the anatomic pathways and the pathophysiologic mechanisms responsible for the development of this association.

The clinical spectrum of severe imported falciparum malaria in the intensive care unit: report of 188 cases in adults.

Little is known about severe imported malaria in nonendemic industrialized countries. The purpose of this retrospective study was to describe the clinical spectrum of severe imported malaria in adults and to determine factors that were present at admission and were associated with in-intensive care unit mortality. This retrospective study evaluated the 188 patients who were admitted to our intensive care unit in 1988-1999 with severe and/or complicated imported malaria. Among them, 93 had strictly defined severe malaria, and 95 had less severe malaria. The mean age was 38 years, 51% of patients were nonimmune whites, 94% acquired Plasmodium falciparum in sub-Saharan Africa, and 96% had taken inadequate antimalarial chemoprophylaxis. Mortality was 11% (10 patients) in the severe malaria group, whereas no patients died in the less severe malaria group (p = 0.002). In the bivariable analysis, the main factors associated with death in the severe malaria group were the Simplified Acute Physiology Score, shock, acidosis, coma, pulmonary edema (p < 0.001 for each), and coagulation disorders (p = 0.002). Bacterial coinfection is not infrequent and may contribute to death. Severe imported malaria remains a major threat to travelers. In our population, the most relevant World Health Organization major defining criteria were coma, shock, pulmonary edema, and acidosis.
