Fatal diphtheria in an older woman.
A previously healthy 68-year-old woman presented with fever and sore throat. Her condition was initially diagnosed as necrotizing streptococcal tonsillitis and was treated with penicillin G, given intravenously. A swab of her throat taken for culture at the time of admission yielded Corynebacterium diphtheriae 48 hours later. At that time an electrocardiogram showed new T-wave inversion--evidence of diphtheritic myocarditis. She was immediately given 60 000 units of equine diphtheria antitoxin (following a test dose), but later that day she began choking, became apneic and died. The patient had not received any immunizing agents as a child, and no antitoxin was detected in a blood sample obtained prior to administration of the antitoxin. Her death re-emphasizes the seriousness of diphtheria, an infection to which many elderly people are susceptible.
