Outbreaks of Mycoplasma pneumoniae (MP) in closed communities can have a high attack rate and can last several months. Azithromycin chemoprophylaxis has not been evaluated as a means of limiting transmission. This randomized, double-blinded placebo-controlled trial of azithromycin was conducted among asymptomatic hospital employees during an MP outbreak. Oropharyngeal swabs were obtained for de...
BACKGROUND Urogenital Chlamydia trachomatis infection remains prevalent and causes substantial reproductive morbidity. Recent studies have raised concern about the efficacy of azithromycin for the treatment of chlamydia infection. METHODS We conducted a randomized trial comparing oral azithromycin with doxycycline for the treatment of urogenital chlamydia infection among adolescents in youth ...
INTRODUCTION Acute respiratory infections (ARI) contribute to more than 75% of health care seeking in primary health care facilities in India. Respiratory tract infections (RTIs) are managed frequently by β-lactam, macrolide and fluroquinolone class of antibiotics. However, these recommended classes of antibiotic have shown resistance in community settings. Antibiotic combinations may provide b...
Although azithromycin is extensively used in the treatment of respiratory tract infections as well as skin and skin-related infections, pharmacokinetics of azithromycin in extracellular space fluid of soft tissues, i.e., one of its therapeutic target sites, are not yet fully elucidated. In this study, azithromycin concentration-time profiles in extracellular space of muscle and subcutaneous adi...
We report the first case in France of a high-level azithromycin-resistant Neisseria gonorrhoeae (minimum inhibitory concentration (MIC) = 96 mg/L) assigned to MLST7363 (NG-MAST ST6360), also resistant to ciprofloxacin and tetracycline but susceptible to ceftriaxone. The patient was a 51 year-old heterosexual man who returned following 1g azithromycin monotherapy. Mechanisms of azithromycin resi...
BACKGROUND Azithromycin has become a frequent choice for the treatment of group A streptococcal (GAS) tonsillopharyngitis. In this study, our objective was to determine the optimal dose of azithromycin for treatment of GAS tonsillopharyngitis in children and adults by analyzing trials that used different dose regimens. METHODS We performed a meta-analysis of randomized, controlled trials that...
The ketolide telithromycin (Ketek, Sanofi Aventis) has been found to be more effective than the macrolide azithromycin (Zithromax, Pfizer) in eradicating Streptococcus pneumoniae from the nasopharynges of patients with acute maxillary sinusitis. Furthermore, the emergence of antimicrobial resistance following therapy occurs only with azithromycin. The growing resistance of S. pneumoniae to peni...
The elastic properties of membrane bilayers are key parameters that control its deformation and can be affected by pharmacological agents. Our previous atomic force microscopy studies revealed that the macrolide antibiotic, azithromycin, leads to erosion of DPPC domains in a fluid DOPC matrix [A. Berquand, M. P. Mingeot-Leclercq, Y. F. Dufrene, Real-time imaging of drug-membrane interactions by...
PURPOSE World Health Organization guidelines for antibiotic treatment of trachoma currently include a 6-week course of tetracycline eye ointment twice daily or a single dose of oral azithromycin. Previous trials have shown similar efficacy of these two alternatives when administration of the ointment was carefully supervised. It is believed, however, that azithromycin may be a more effective tr...
A single dose of a novel formulation of azithromycin microspheres (Pfizer) has proved to be as effective as a seven-day course of levofloxacin (Levaquin®, Ortho-McNeil) for the treatment of an acute exacerbation of chronic bronchitis (AECB). This advance has made it possible to administer an entire regimen as a single oral dose while maintaining tolerability and efficacy. In a multicenter, rand...
