Erythromycin resistance in Streptococcus pyogenes in Italy.
نویسندگان
چکیده
In a prospective study of acute pharyngitis in Italian children, 69 (38.3%) of 180 isolates of Streptococcus pyogenes were resistant to macrolides. S. pyogenes was eradicated in 12 (63.1%) of 19 patients with erythromycin-resistant S. pyogenes treated with clarithromycin and in 22 (88%) of 25 patients with erythromycin-susceptible strains. The constitutive-resistant phenotype was correlated with failure of macrolide treatment.

A survey of antibiotic resistance in Streptococcus pyogenes in Italy showed a sharp increase in erythromycin resistance. In 1993, the incidence of erythromycin-resistant strains was on average 5.1%, with marked variations by geographic area. Two years later, the incidence of these strains had registered a 1.5- to roughly 20-fold increase, with a mean value of 25.9%, exceeding 40% in three cente...
متن کاملA regionwide intervention to promote appropriate antibiotic use in children reversed trends in erythromycin resistance to Streptococcus pyogenes.
Streptococcus pyogenes is the major bacterial pathogen responsible for acute pharyngitis in children. Oral penicillin is the drug of choice for streptococcal pharyngitis, while macrolides are an alternative option for patients allergic to penicillin. The frequent use of macrolides promotes the spread of erythromycin resistance (1-2), but reducing the use of these antibiotics has been correlated...
متن کاملMacrolide prescriptions and erythromycin resistance of Streptococcus pyogenes.
This study shows a significant association between the number of macrolide prescriptions reimbursed by the Italian National Health Service and resistance of Streptococcus pyogenes to erythromycin in children from a region in northern Italy with high prevalence of erythromycin resistance. Recent prescription of a macrolide (especially azithromycin) is a predictor of erythromycin resistance, as w...

Many studies have shown a correlation between higher consumption of long-acting macrolides and the development of resistance of S. pyogenes but, to our knowledge, no studies have reported the disappearance of S. pyogenes macrolide resistance. We evaluated the possible relationship between the rational use of long-acting macrolide consumption and the disappearance of S. pyogenes erythromycin res...
متن کاملIn vitro activity of ketolides telithromycin and HMR 3004 against italian isolates of Streptococcus pyogenes and Streptococcus pneumoniae with different erythromycin susceptibility.
Two ketolides, telithromycin and HMR 3004, were evaluated for their in vitro activity against erythromycin-susceptible and -resistant strains of Streptococcus pyogenes and Streptococcus pneumoniae. On the basis of their resistance to macrolide, lincosamide and streptogramin (MLS) antibiotics, erythromycin-resistant test strains were assigned to the constitutive resistance (cMLS) phenotype, the ...
