title: Antibiotic-associated pseudomembranous colitis in children.
abstract: Antibiotic-associated colitis is a rare complication of antimicrobial therapy in children. Ampicillin, penicillin, and clindamycin are the drugs most frequently reported to cause pseudomembranous colitis in pediatric patients. This diagnosis should be suspected in any child with significant diarrhea during or after a course of antimicrobial therapy, especially if the diarrhea persists after the drug has been discontinued. The diagnosis is established by proctoscopic findings of typical plaques of pseudomembranes. Most cases resolve promptly when the implicated antibiotic is stopped; however, the disease can be fulminant, progressing to toxic megacolon, peritonitis, and shock. Therapy of patients who have persistent diarrhea after the offending antibiotic has been discontinued should include oral vancomycin. Close fluid management is crucial for survival.
