Treatment and prevention of pertussis by antimicrobial agents (Part II)
Abstract:
Suitable antimicrobials given during the catarrhal stage of whooping cough can attenuate the course of the disease. The efficacy of antibiotics administered prophylactically during the incubation period remains controversial but appears to be beneficial. Currently, erythromycin given for two weeks is the antibiotic of choice for pertussis. No treatment failures were observed with erythromycin estolate. Erythromycin ethylsuccinate and stearate must be given at high dosages (50-60 mg/kg/day) in order to achieve sufficient concentrations in the respiratory secretions. With ampicillin and amoxicillin treatment failures have been observed. The role of josamycin and co-trimoxazole in pertussis remains open.
Insights
Early antibiotic treatment for whooping cough (pertussis) can shorten the illness. Erythromycin is the preferred antibiotic, though other options like ampicillin and amoxicillin have shown treatment failures.
Area of Science:
- Infectious Diseases
- Microbiology
- Pharmacology
Background:
- Whooping cough (pertussis) is a contagious respiratory illness.
- Antimicrobial therapy during the early stages can impact disease severity.
- The prophylactic use of antibiotics during pertussis incubation is debated.
Purpose of the Study:
- To review the efficacy of antimicrobial agents in treating pertussis.
- To evaluate the role of antibiotics in different stages of whooping cough.
- To identify optimal antibiotic choices and dosages for pertussis management.
Main Methods:
- Literature review of existing studies on pertussis treatment.
- Analysis of clinical data regarding antibiotic efficacy and treatment failures.
- Comparison of different antimicrobial agents, including erythromycin, ampicillin, amoxicillin, josamycin, and co-trimoxazole.
Main Results:
- Antimicrobials administered during the catarrhal stage can reduce disease duration.
- Erythromycin is the current antibiotic of choice for pertussis.
- Erythromycin estolate showed no treatment failures; high dosages of ethylsuccinate and stearate are needed for respiratory secretions. Ampicillin and amoxicillin have been associated with treatment failures.
Conclusions:
- Early antimicrobial intervention is beneficial for managing whooping cough.
- Erythromycin is effective, but specific formulations and dosages are critical.
- Further research is needed to clarify the roles of josamycin and co-trimoxazole in pertussis treatment.
