STUDY OBJECTIVES To study circulatory endotoxin (ET) in patients with sepsis syndrome (SS) in order to answer three questions: (a) How often and at which concentration is ET present in the plasma of patients with SS and is the presence of ET a prognostic marker in this situation? (b) Is detection of ET helpful in predicting Gram-negative bacterial(More)
Increasing resistance to multiple antimicrobial agents including penicillins is a current problem with Streptococcus pneumoniae. Seven cases of severe infection due to penicillin G-resistant pneumococci were seen in two teaching hospitals in Paris (France) during the first half of 1991; six of the strains were recovered from pulmonary secretions (protected(More)
Clinical isolate Pseudomonas aeruginosa Mus showed resistance both to extended-spectrum cephalosporins and to aztreonam. We detected a typical double-disk synergy image when ceftazidime or aztreonam was placed next to a clavulanic acid disk on an agar plate. This resistance phenotype suggested the presence of an extended-spectrum beta-lactamase. Isoelectric(More)
Central venous catheters (CVC) are an important source of nosocomial infection in intensive care units. The unnecessary removal of CVC suspected to be infected can probably be minimized. In order to test the accuracy of non-invasive methods for predicting catheter colonization, we prospectively compared the results of 50 consecutive CVC tip cultures, with(More)
The impact of antibiotics on total endotoxemia and circulating tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, and IL-8 in 18 patients with severe bacteremic sepsis or septic shock due to gram-negative species was investigated. Endotoxemia, TNF-alpha, IL-6, and IL-8 were assayed before (H0) and 1 h (H1) and 4 h (H4) after the first antibiotic(More)
A 44-year-old alcoholic Frenchman of no fixed abode was admitted to our hospital in September 1991 with delirium tremens, fever, visual and auditory hallucinations, and mental confusion. The time of onset of fever before admission was unclear on questioning the patient after admission because the patient had memory problems related to a long history of(More)
Circulatory secretory non-pancreatic phospholipase A2 (snp-PLA2) was measured prospectively at the onset (day 0) of severe sepsis in 52 patients as well as on day 1 and 2 in 25 patients, in order to answer two questions: 1) does the snp-PLA2 plasma concentration differ according to the type and severity of infection? 2) what is the relation between snp-PLA2(More)
BACKGROUND Tirofiban at the bolus dose of 10 microg/kg does not suppress the inflammatory response following percutaneous coronary intervention (PCI). This may be due to less than optimal inhibition of platelet aggregation. High bolus dose tirofiban (25 microg/kg) allows better inhibition of platelet aggregation but its anti-inflammatory effect remains(More)
The killing kinetics of cefotaxime and fosfomycin, alone and in combination, against seven clinical isolates of penicillin-resistant pneumococci were studied. The antibiotics were tested at 1 x, 2 x and 4 x the MIC for each individual isolate. The results showed a synergic interaction of the two antibiotics for three of the seven strains. This strategy may(More)
