BACKGROUND Because clarithromycin provided beneficiary nonantibiotic effects in experimental studies, its efficacy was tested in patients with sepsis and ventilator-associated pneumonia (VAP). METHODS Two hundred patients with sepsis and VAP were enrolled in a double-blind, randomized, multicenter trial from June 2004 until November 2005. Clarithromycin (1 g) was administered intravenously on...
BACKGROUND Subinhibitory levels of clarithromycin and azithromycin have been shown to reduce the activity of bacterial virulence factors, but few studies have examined the effects of subinhibitory levels of telithromycin. Here, we examined the effects of telithromycin, clarithromycin and azithromycin on methicillin-resistant Staphylococcus aureus (MRSA) coagulase in vitro. We also examined the ...
Background: Chronic sinusitis is one of the most common medical problems affecting 30 million people in USA annually. In the present study, we compared the efficacy and safety of clarithromycin XL and co-amoxiclav on clinical and CT scan findings of patients suffering from chronic sinusitis. Patients and methods: In this clinical trial, a total of 59 subjects (37 males and 22 females, mean age ...
The prevalence of chronic obstructive pulmonary disease (COPD) is increasing in under-developing and developing countries. As per current estimations, COPD will become the third leading cause of death globally, by 2030. Long-acting anti-cholinergic agents, β2-agonists, inhaled corticosteroids, antibiotics and mucolytics are few of the agents currently used in the treatment of COPD, which improv...
CYP3A4-inhibitors can potentiate the hypotensive effect of calcium-channel blockers. However, insufficient attention to such drug interactions may result in serious adverse reactions. A 71-year-old hypertensive man prescribed nifedipine was hospitalized for infectious endophthalmitis. Antimicrobial therapy with voriconazole lowered the blood pressure, and then clarithromycin further lowered it ...
We investigated the effects of azithromycin and clarithromycin, two antibiotics that possess a broad spectrum of antimicrobial activity (including antimycobacterial activity), on interleukin-8 (IL-8) release from human whole blood leucocytes and lung macrophages. Ex vivo stimulation of leukocytes with either of the antibiotics (0.04-40 mg/L) significantly increased IL-8 secretion. Incubation of...
OBJECTIVE The aim of this study was to evaluate the prevalence of resistance among 83 Helicobacter pylori isolates cultured from biopsies taken during routine endoscopies in 1998-1999. METHODS Minimum Inhibitory Concentration of amoxicillin, tetracycline, clarithromycin and metronidazole were determined by Epsilometer test. RESULTS Forty-seven strains (57%) were resistant to metronidazole, ...
results of the 135 h. pylori-positive specimens, two harbored strains with the a2143g mutation and nine contained strains with the a2144g mutation. thus, the prevalences of the a2143g and a2144g point mutations were 1.5% and 6.7%, respectively. the a2143c point mutation was not found. conclusions the prevalences of the point mutations a2143g and a2144g were low in our geographic area. based on ...
