Abstract
The Kyrgyz Republic experienced a widespread resurgence of diphtheria during 1994–1998. To describe the clinical characteristics and management of diphtheria patients hospitalized in 1995, a retrospective chart review was conducted. Physician-diagnosed cases of diphtheria were classified according to the system recommended by the World Health Organization and UNICEF. Among 676 patients hospitalized with respiratory diphtheria, 163 (24%) were carriers, 186 (28%) had tonsillar forms, 78 (12%) had combined types or delayed diagnosis, and 201 (30%) had severe forms of diphtheria. The highest age-specific incidence rates occurred among persons 15–34 years old, and 70% of cases were among those ⩾15 years of age. Myocarditis occurred among 151 patients (22%), and 19 patients died (case fatality ratio: 3%). Diphtheria antitoxin was administered to 507 patients (75%), and all patients received antibiotics (penicillin or erythromycin). Respiratory diphtheria remains a potentially fatal disease, commonly presenting with a typical membranous pharyngitis. Early diagnosis and treatment of cases with diphtheria antitoxin and antibiotics are the cornerstones of effective treatment.
