Treatment of Typhoid Fever in Children and Adolescents
Recommended First-Line Therapy
- The American Academy of Pediatrics recommends azithromycin as the first-line treatment for typhoid fever in children and adolescents, with a dosage of 20 mg/kg/day (maximum 1g/day) for 7 days 1, 2
- For adolescents and adults, the recommended dosage is 500 mg once daily for 7-14 days 1, 2
Comparison with Other Antibiotics
- Azithromycin has a lower risk of clinical failure (OR 0.48) compared to fluoroquinolones 1, 2
- The length of hospital stay is shorter by approximately 1 day (mean difference -1.04 days) with azithromycin 1, 2
- Azithromycin has a significantly lower risk of relapse (OR 0.09) compared to ceftriaxone 1, 2
- The cure rate with azithromycin is 94% in children with typhoid fever 3
Alternative Therapies
- Ceftriaxone is a second-line option, with a dosage of 50-80 mg/kg/day IV/IM (maximum 2g/day) for 5-7 days 4, 2
- Cefixime is an alternative option, but it has a higher risk of treatment failure (4-37.6%) and requires a test-of-cure on week 1 1, 2
Monitoring and Expected Response
- Fever should resolve within 4-5 days of appropriate antibiotic therapy 1, 2, 3
- If there is no improvement by day 5, consider resistance or alternative diagnoses 2
Potential Complications
- Intestinal perforation occurs in 10-15% of patients when the disease duration exceeds 2 weeks 1, 2
- Surgical intervention is required, with a success rate of 88.2% 1, 2
