Clindamycin treatment of osteomyelitis and septic arthritis in children.
Forty-eight children, 1 month to 14 years of age, including 11 patients with untreated acute osteomyelitis, 8 with pretreated acute osteomyelitis, 12 with septic arthritis, and 11 with cellulitis or soft tissue abscess, were treated with clindamycin. Staphylococcus aureus was isolated from the blood, synovial fluid, bone, or soft tissues of 27 of these individuals while group A, beta-hemolytic streptococci or Clostridia were isolated from 9 patients. Clindamycin was provided intravenously until patients were afebrile for three days followed by orally administered clindamycin for one week in patients with cellulitis to as long as six months in patients with chronic osteomyelitis. Clinical and bacteriologic responses to treatment generally were excellent, most likely reflecting the excellent serum and tissue concentrations of clindamycin which were achieved. Serum concentrations of clindamycin following intravenous infusion at 20 to 30 mg/kg/day in three divided doses were 8- to 32-fold in excess of the minimal inhibitory concentrations of all organisms isolated in this study. Bone and synovial fluid concentrations of clindamycin were 60% to 85% of the serum concentrations measured concomitantly. Clindamycin provides an effective alternative treatment of osteomyelitis and septic arthritis in children who are sensitive to penicillin.
