We determined the clinical potential of cefazolin by assaying aqueous samples for levels of aqueous penetration of cefazolin in humans and rabbits after subconjunctival injection. Cefazolin is a broad spectrum antiotic that appears to penetrate aqueous humor in bactericidal concentrations after subconjunctival injection and may serve as a useful alternative in patients sensitive to other antibi...

BACKGROUND Bacterial contamination during cold organ preservation occurs without major complications. However, with organ preservation steering toward (sub)normothermic temperatures, bacterial contamination may be detrimental with limited evidence to support the choice of antibiotic. METHODS This study aimed to determine the effective antibiotic prophylaxis for (sub)normothermic preservation ...

We studied the effect of the control of the hypothyroid state in humans on the pharmacokinetic parameters of cefazolin and gentamicin after a single intravenous injection. These two antibiotics were chosen because of their different patterns of binding to serum albumin (0% for gentamicin and 82% for cefazolin). In hypothyroidism, the behavior of cefazolin only was altered, with a decrease in th...

Serum and urinary levels of cefazolin were determined after a 500-mg parenteral dose in eight azotemic volunteers. The mean peak serum concentration was 1.5 to 5 times the levels obtained in nonazotemic patients. The serum half-life of cefazolin was increased significantly. In patients on dialysis, the mean serum half-life of cefazolin was 4.05 h during (or after) hemodialysis, and 32.1 h durin...

Several reports have implicated the inoculum effect that some strains of type A beta-lactamase (Bla)-producing, methicillin-susceptible Staphylococcus aureus (MSSA) show against cefazolin as the cause for clinical failures in certain serious deep-seated infections. Here, using a previously reported MSSA strain displaying this phenotype (TX0117), we obtained a Bla-cured derivative (TX0117c) with...

Cefazolin injection (3000 mg/kg, i.v.) in mice showed several behavioral excitations such as wild running, jumping, rolling, and finally undergoing severe convulsions followed by death. It's lower doses (500-2000 mg/kg, i.v.) were unable to produce any convulsions or behavioral excitations in mice. However, cefazolin (500 or 1000 mg/kg, i.v.) when administered before different doses of pentylen...

conclusion we suggest the standard cefazolin prophylaxis (after cord clamping) for elective cesarean section and cefazolin before incision for non elective cesarean section. therefore, administration of prophylactic cefazolin prior to incision will not increase the rate of neonatal sepsis. compared between these groups. results two groups were demographically identical. rate of iv line need (rr...

The objective of the present study was to assess the safety and tolerability of cefazolin therapy among patients with methicillin-sensitive Gram-positive bacterial infections who develop non-IgE-mediated hypersensitivity reactions (HSRs) to nafcillin. In this retrospective cohort analysis of the Outpatient Parenteral Antimicrobial Therapy program at the Massachusetts General Hospital from 2007 ...

To determine whether the infection-preventing capability of the neutrophil-activating agent poly-(1-6)-b-Dglucopyranosyl-(1-3)-b-D-glucopyranose glucan (PGG-glucan) can be enhanced with antibiotic prophylaxis, we administered PGG-glucan and cefazolin, alone and in combination, to guinea pigs inoculated with isolates of staphylococci. Guinea pigs receiving both PGG-glucan and cefazolin had 50% i...

Introduction: Drug-induced immune hemolytic anemia (DIIHA) is known as an unpredictable and in some cases serious complication occurring upon pharmacotherapy. Cefazolin, as a first generation cephalosporin used against gram-negative bacteria, has rarely been reported to cause hemolytic anemia. Here, we report the first fatal case of hemolytic anemia associated with cefazolin treatment. Material...
