Floxacillin-induced cholestatic hepatitis with evidence of lymphocyte sensitization.

A severe and prolonged form of biopsy-proved cholestatic hepatitis occurred in a 45-year-old man who had received floxacillin for two weeks preceding the episode of drug-related cholestatic injury. Immunologic tests revealed evidence of in vitro sensitization to the drug as well as to the serum of a normal subject collected after ingestion of floxacillin. Floxacillin should be added to the list of drugs causing cholestatic hepatitis, most likely by an immunologic mechanism.

Preparation and immunological cross-reactions of penicilloic and penilloic acids.

Methods are described for the preparation of pure crystalline samples of the penicilloic and penilloic acids of penicillin G, carbenicillin, cloxacillin, floxacillin, methicillin, penicillin V, and ticarcillin and the penicilloic acids of amoxicillin, ampicillin, phenethicillin, and propicillin. The interaction between the compounds and rabbit antibenzylpenicilloyl antibodies was evaluated by hemagglutination inhibition measurements. A significant correlation was found in this system between the reactivity of penicilloic acids and the corresponding penilloic acids; on average, the penicilloic acids were more reactive on a molar basis by a factor of 11. The results are discussed in terms of the general immunochemistry and side-chain structure of the parent penicillins.

Infected false aneurysms in the groin of intravenous drug abusers.

The hazards of dealing with infected false femoral aneurysms resulting from intra-arterial narcotic injection are highlighted in six patients. Two patients were human immunodeficiency virus positive and three patients were hepatitis B surface antigen positive. Because of these infections exploration of groin swellings as presumed soft tissue abscesses is potentially hazardous without proper proximal vascular control. All patients underwent reconstruction following arterial ligation and five grafts became infected, with life threatening haemorrhage occurring in four patients. Five grafts have subsequently occluded or have been removed without loss of limb viability, although two patients have been regrafted. A high index of suspicion and assessment by a vascular surgeon, with angiography if indicated, is required in any intravenous drug abuser presenting with a groin swelling following injection. Because of the great risk of graft infection, it is suggested that ligation and debridement alone be carried out, with immediate arterial reconstruction only for non-viability.

The role of piperacillin therapy in pulmonary exacerbations of cystic fibrosis: a controlled study.

Piperacillin was evaluated as an antipseudomonas antibiotic in a double-blind controlled trial involving 18 pulmonary exacerbations of cystic fibrosis. Standard antibiotic treatment (flucloxacillin plus tobramycin) was compared with standard treatment plus intravenous piperacillin administered according to two regimens. No added benefit from piperacillin was demonstrable on the basis of improvement in symptoms, physical signs, weight gain, pulmonary function tests, radiologic signs, or sputum Pseudomonas bacterial counts. Some patients experienced sensitivity reactions to piperacillin. In vitro, piperacillin was a potent antibiotic against all beta-lactamase-producing mucoid strains of Pseudomonas aeruginosa; however, in spite of the fact that adequate serum antibiotic concentrations were achieved, sputum bacterial counts did not correlate with either the clinical status or the use of piperacillin therapy.

Infective iliopsoas bursitis. A case report.

We report a case of infective iliopsoas bursitis, and to our knowledge a similar case has not been described. The anatomical relation between the bursa and the hip, and related pathological conditions are reviewed. The contribution of CT-guided catheterisation is emphasised as it allows aspiration of fluid, injection of radio-opaque material and lavage.

Pharmacokinetics of free and total flucloxacillin in newborn infants.

Flucloxacillin 50 mg/kg b.w. was administered intravenously (in combination with ampicillin/gentamicin) and orally (with amoxicillin) to 9 newborn infants (gestational age 33-41 weeks) to treat bacterial infections. The concentrations of flucloxacillin in plasma and urine after i.v. injection were analysed according to an open two-compartment model, and the plasma protein binding of flucloxacillin and its distribution to blood cells and plasma water in whole blood were determined. Considerable differences were found from values reported in adults. The terminal half-life averaged 4 h 38 min and was significantly correlated with gestational age. Plasma clearance was low (0.744 ml X min-1 X kg-1), due to the small renal clearance (0.182 ml X min-1 X kg-1), whilst non-renal clearance (0.563 ml X min-1 X kg-1) was approximately the same as in adults. The mean apparent volume of distribution of total drug (Vz) was 0.280 l/kg. The corresponding volume of distribution of unbound drug (Vu1 + Vu2) was 1.74 l/kg, which indicates considerable extravascular drug binding. The plasma protein binding of flucloxacillin (mean 86.3%) was significantly correlated with gestational age and the bilirubin/albumin concentration ratio. Bioavailability after oral administration, when corrected for changes in terminal half-life, was 47.7%, which is only slightly lower than that reported in adults. Since the plasma concentrations after both i.v. and oral administration were well above the MIC-values generally reported for Staphylococcus aureus, and since few side-effects were observed, intravenous injection or, in selected cases, orl administration of flucloxacillin appears to be a reliable therapy for the treatment of infections due to sensitive strains of S. aureus in premature newborn infants.

Pharmacokinetics and distribution of flucloxacillin in pacemaker patients.

The pharmacokinetics of flucloxacillin in plasma and tissue fluid after i.v. infusion of 1 g was analyzed according to an open two-compartment model in 19 patients with bradyarrhythmias (mean age 70.8 years) admitted for implantation or replacement of a permanent pacemaker system. After the first infusion of flucloxacillin (5 min), the distribution phase was rapid (t 1/2 alpha = 0.13 h). The plasma half-life of elimination (t 1/2 beta) was 1.51 h, which is almost twice as long as reported in healthy volunteers. Total plasma clearance (93.1 ml/min) was also lower than is usually found in healthy individuals, due to low renal clearance of flucloxacillin (60.2 ml/min). The total apparent volume of distribution during the beta-phase (Vdarea) was 0.172 l/kg and distribution in the central compartment (Vc) 0.064 1/kg. In each patient plasma protein binding and drug distribution to plasma water, proteins and blood cells in whole blood were determined. Binding in plasma to proteins was 91.0% and distribution to blood cells in whole blood 13.8%. The mean distribution volume of free flucloxacillin during the beta-phase (Vd beta free) was 2.18 1/kg, which exceeds total body water, suggesting possible intracellular distribution and substantial tissue binding. Plasma concentrations of flucloxacillin after the fourth dose (1 g t.i.d.) were very similar to those obtained after the first infusion and those predicted from the single dose kinetics. The concentration of flucloxacillin in fluid from the pacemaker pockets in 5 patients averaged 12.1 micrograms/ml and 9.5 micrograms/ml at 1 and 5 h, respectively, which was more than ten times the MIC-values for Staphylococcus aureus and S. epidermidis.(ABSTRACT TRUNCATED AT 250 WORDS)

Flucloxacillin compared with cefazolin in short-term prophylaxis for clean orthopedic surgery.

Two-hundred and fifty-two patients were included in a prospective, randomized, double-blind trial comparing the efficacy of flucloxacillin with that of cefazolin for clean orthopedic surgery. The preventive antibiotic regimen consisted of three 1-g injections perioperatively. There were 126 patients in each group, and the follow-up period was at least 6 months. Two deep (1.6%) and five superficial (4.0%) infections occurred in the flucloxacillin group. Three deep (2.4%) and five superficial (4.0%) infections developed in the cefazolin group.

The influence of flucloxacillin and amoxicillin with clavulanic acid on the aerobic flora of the alimentary tract.

In a randomized study, 42 patients undergoing extensive maxillo-facial surgery (correction of the position of the mandible or maxilla by using autologous bone transplants) received prophylactically ten-day courses of either flucloxacillin or amoxicillin with clavulanic acid. Patients were comparable with regard to age and type of surgery. During the prophylactic treatment the effect of antibiotics used on the microbial flora of the alimentary tract was studied. Patients receiving flucloxacillin showed increased numbers of Klebsiella spp. isolated from the faeces (59% of the patients versus 19% of the patients receiving amoxicillin with clavulanic acid). Patients receiving amoxicillin with clavulanic acid showed higher colonization rates of oropharynx with Enterobacteriaceae than patients receiving flucloxacillin (ten patients versus five patients). 60% of those strains isolated from patients receiving amoxicillin with clavulanic acid were resistant to this combination, as compared to 20% of gram-negative bacilli isolated from patients receiving flucloxacillin. In 50% of patients receiving amoxicillin with clavulanic acid, colonization of the gut with yeast occurred, as compared to 18% of patients receiving flucloxacillin. Only one infection leading to a partial loss of the graft was seen in the group of patients receiving flucloxacillin.

Efficacy of penicillin G, flucloxacillin, cefazolin, fusidic acid, vancomycin, rifampicin and fosfomycin in muscular infections in mice due to Staphylococcus aureus.

Two strains each of sensitive, penicillinase-producing, methicillin-resistant and "tolerant" Staphylococcus aureus were used to infect mice intramuscularly. The mice were then treated with three doses each of fosfomycin, vancomycin, rifampicin, fusidic acid, penicillin G, flucloxacillin or cefazolin intravenously. Infections due to sensitive strains were effectively treated with all antibiotics investigated except fusidic acid. Fosfomycin, vancomycin, rifampicin and flucloxacillin showed the best activity against penicillinase-producing strains. Fosfomycin and vancomycin were equally effective against infections due to methicillin-resistant S. aureus. Infections caused by "tolerant" strains again responded best to fosfomycin, vancomycin and rifampicin.
