Gentamicin nephrotoxicity is one of the most common causes of acute kidney injury (AKI). Hypoxia-inducible factor (HIF) is effective in protecting the kidney from ischemic and toxic injury. Increased expression of HIF-1α mRNA has been reported in rats with gentamicin-induced renal injury. We hypothesizd that we could study the role of HIF in gentamicin-induced AKI by modulating HIF activity. In...

The reasons why aminoglycosides are bactericidal have not been not fully elucidated, and evidence indicates that the cidal effects are at least partly dependent on iron. We demonstrate that availability of iron markedly affects the susceptibility of the facultative intracellular bacterium Francisella tularensis strain SCHU S4 to the aminoglycoside gentamicin. Specifically, the intracellular dep...

objective(s): the aim of this study was to evaluate the effect of subacute administration of propylthiouracil (ptu) on gentamicin (gm)-induced nephrotoxicity in male rats.   materials and methods: male wistar rats were divided into 4 experimental groups as follow: (1) control group: isotonic saline (1 ml/kg, ip. for 18 d), (2) gm group: 100 mg/kg, ip for 8 d, (3) ptu group: ptu (10 mg/kg, ip fo...

The increasing gentamicin resistance among bacteria in septic joint arthroplasty has stimulated interest in adding a second antibiotic into gentamicin-loaded bone cement. A first aim of this in vitro study is to investigate whether addition of fusidic acid or clindamycin to gentamicin-loaded bone cement has an additional antimicrobial effect against a collection of 38 clinical isolates, includi...

BACKGROUND Recent studies described an increase in acute kidney injury when high dose gentamicin was included in perioperative prophylaxis for orthopedic surgeries. To this effect, we compared the rate of nephrotoxicity for selected orthopedic surgeries where gentamicin was included (Gentamicin Group) to those where it was not included (Control Group) for perioperative prophylaxis and evaluated...

Zager RA, Johnson AC, Geballe A. Gentamicin suppresses endotoxin-driven TNFproduction in human and mouse proximal tubule cells. Am J Physiol Renal Physiol 293: F1373–F1380, 2007. First published August 15, 2007; doi:10.1152/ajprenal.00333.2007.— Gentamicin is a mainstay in treating gram-negative sepsis. However, it also may potentiate endotoxin (LPS)-driven plasma TNFincreases. Because gentamic...

A mutant strain of Micromonospora purpurea, designated var. JI-33, produced an antibiotic complex consisting primarily of gentamicin C1a. A further product of this fermentation was identical to a very minor component isolated from the fermentation of the parent organism and named gentamicin C2b. Physical measurements indicated its structure to be 6'-N-methylgentamicin C1a and this was confirmed...

The effects of ceftizoxime and gentamicin alone and in combination were determined against 100 Pseudomonas aeruginosa strains. Concentrations of 32 micrograms of ceftizoxime and 8 micrograms of gentamicin per ml inhibited 22 and 43% of the strains, respectively. At concentrations of ceftizoxime and gentamicin that are readily achievable in serum, 15 strains were affected synergistically and 17 ...

Mycoplasma gallisepticum is the major mycoplasmal pathogen in poultry. The present study was undertaken to evaluate the efficacy of six commonly used antimicrobials, including difloxacin, enrofloxacin, ciprofloxacin, doxycycline, gentamicin, and valnemulin, against Mycoplasma gallisepticum, using a Monte Carlo simulation based on the pharmacokinetics-pharmacodynamic (PKPD) theory. The ratio of ...

PURPOSE To evaluate the analgesic action of combined indomethacin 0.1%/gentamicin eyedrops in traumatic corneal abrasion. METHODS We evaluated 123 patients presenting traumatic corneal abrasion in a multicentre, randomised, double-masked study comparing two parallel treatment groups: indomethacin/gentamicin (group 1) or gentamicin alone (group 2). Study treatments were administered four times...
