Abstract:
From 1974 to 1983, inclusive, 274 children with acute suppurative osteoarticular infections were treated with antibiotic regimens that were shorter than usually recommended. The median duration of antibiotic treatment for acute suppurative arthritis caused by staphylococci, streptococci, Haemophilus influenzae type b, gram-negative cocci, or other gram-negative bacteria was 23, 16, 16, 15, and 22 days, respectively. For acute osteomyelitis caused by staphylococci, streptococci, H influenzae, or other gram-negative bacteria the median duration of antibiotic therapy was 24, 23, 17, and 22.5 days, respectively. Osteoarthritis usually had to be treated for about a month. 180 patients received large dosages of oral antimicrobials after clinical stabilisation with intravenous treatment, the median duration of intravenous therapy being about a week (range up to 7 weeks). 99% of patients underwent needle aspiration for diagnostic reasons. 36%, 71%, and 63% of the patients with acute suppurative arthritis, osteomyelitis, and osteoarthritis, respectively, underwent incision and drainage. Recurrence occurred in 4 patients with acute osteomyelitis (3.8% of cases). There was no recurrence of arthritis.
Insights
Shorter antibiotic regimens for pediatric osteoarticular infections were effective, with low recurrence rates for osteomyelitis and no recurrence for arthritis. This study evaluated outcomes in 274 children.
Area of Science:
- Pediatric Infectious Diseases
- Orthopedic Surgery
- Pharmacology
Background:
- Acute suppurative osteoarticular infections in children often require prolonged antibiotic treatment.
- This study investigates the efficacy of shorter antibiotic regimens in pediatric patients.
Observation:
- 274 children with acute suppurative osteoarticular infections were treated between 1974 and 1983.
- Median antibiotic treatment durations varied by pathogen and infection type (arthritis vs. osteomyelitis).
- Surgical interventions like needle aspiration and incision/drainage were frequently employed.
Findings:
- Shorter antibiotic durations were used, with median treatment ranging from 15 days (gram-negative cocci arthritis) to 24 days (staphylococcal osteomyelitis).
- Most patients received oral antimicrobials after initial intravenous therapy.
- Recurrence rates were low: 3.8% for osteomyelitis and 0% for arthritis.
Implications:
- Shorter antibiotic courses may be a viable treatment option for pediatric osteoarticular infections, potentially reducing treatment burden.
- Findings support the judicious use of antibiotics and surgical interventions in managing these conditions.
- Further research could explore optimal durations based on specific pathogens and clinical presentation.
