Abstract:
We conducted an open-label randomized controlled trial to compare the efficacy and safety of clarithromycin (15/mg/kg/day in 2 divided doses for 7 days) with those of azithromycin (10 mg/kg/day in 1 dose for 3 days) in the treatment of children with Mediterranean spotted fever. Until now, there has not been a gold-standard therapy for this rickettsial disease in children. Eighty-seven children were randomized to receive 1 of the 2 drugs. The mean time to defervescence (+/- standard deviation) was 46.2+/-36.4 h in the clarithromycin group and 39.3+/-31.3 h in the azithromycin group. These differences were not statistically significant and both drugs were equally well-tolerated. Clarithromycin and azithromycin could be acceptable therapeutic alternatives to chloramphenicol and tetracyclines for children aged < or =8 years with Mediterranean spotted fever. Azithromycin, because it has a long half-life, offers the advantages of administration in a single daily dose and a shorter duration of therapy, which could increase compliance in children.
Insights
This study found that both clarithromycin and azithromycin are effective treatments for Mediterranean spotted fever in children. These antibiotics offer safe alternatives for treating this rickettsial disease.
Area of Science:
- Pediatrics
- Infectious Diseases
- Pharmacology
Background:
- Mediterranean spotted fever is a rickettsial disease in children lacking a gold-standard therapy.
- Current treatment options like chloramphenicol and tetracyclines have limitations for pediatric use.
Purpose of the Study:
- To compare the efficacy and safety of clarithromycin versus azithromycin for treating Mediterranean spotted fever in children.
- To identify potential alternative antibiotic therapies for this pediatric rickettsial infection.
Main Methods:
- An open-label randomized controlled trial involving 87 children diagnosed with Mediterranean spotted fever.
- Participants were randomized to receive either clarithromycin (15 mg/kg/day in 2 doses for 7 days) or azithromycin (10 mg/kg/day in 1 dose for 3 days).
- Efficacy was assessed by time to defervescence, and safety was evaluated through tolerability.
Main Results:
- The mean time to defervescence was 46.2 ± 36.4 hours for clarithromycin and 39.3 ± 31.3 hours for azithromycin.
- No statistically significant difference in the time to defervescence was observed between the two treatment groups.
- Both clarithromycin and azithromycin were equally well-tolerated by the pediatric patients.
Conclusions:
- Clarithromycin and azithromycin are acceptable therapeutic alternatives for children aged 8 years or younger with Mediterranean spotted fever.
- Azithromycin's single daily dose and shorter treatment duration may improve patient compliance.
- These macrolides offer safer alternatives to chloramphenicol and tetracyclines in pediatric cases.
