Twenty-five infants and children with acute osteomyelitis suppurative arthritis or both were treated with imipenem and cilastatin sodium. Patients ranged in age from 5 months to 11.3 years. Needle aspiration of infected sites was performed in all patients, and 11required further surgicalgical drainage. Imipenem and cilastatin sodium in a dosage of 100 mg/kg/d was used for children 3 years of age or younger, while older ones received 60 mg/kg/d intravenously, divided in four eququal doses. Bacterial pathogens were identified in 15 patients Staphylococcus aureus in five, Haemophilus inluenzae b in four, Pseudomonas aeruginosa in two, Streptococcus pneumoniae in one, group A Streptococcus in one, Kingella kingae in one, and Citrobacter amalonaticus in one. All isolates Were susceptible to imipenem in vitro. mipenem and cilastatin therapy was continued for a median of six days followed by treatment with appropriate orally administered antibiotics. Median peak serum bactericidal titers after imipenem and cilastatin infusions were 11:512 ffor S aureus, 11:32 for H influenzae b, 11:512 for streptococci, and 11:16 for gramnegative rods. All but one patient with P aeruginosa osteomyelitis responded favorably to imipenem and cilastatin. The median duration until resolution of symptoms was six days. Imipenem and cilastatin infusions were well tolerated, and side effects included maculopapular rash in one patient, watery diarrhea in one, and mild transient elevation of alanine aminotransferase levels in three. Because of imipenem and cilastatin's unusually broad spectrum of activity and its relative safety, this drug combination can be used for the initial, empiric therapy of acute bone and joint infections in pediatric patients.
