[Sydenham's chorea in Tunisia: a report on 65 cases (author's transl)]

Abstract

Sydenham's chorea was observed in 65 patients in Tunisia during the period 1971-1976. The average age of onset was 10.8 years, and girls were affected twice as often as boys. Sydenham's chorea is a seasonal disorder; it usually develops between the months of november and march, and its frequency is closely related to that of Bouillaud's disease. A study of the past history of infections disease or rheumatic disorder (ARF), and biological tests for inflammation (sedimentation rate, blood fibrin levels, antistreptolysins O, and culture of throat swabs), showed that it is possible to distinguish cases of true chorea occurring alone from those in which it is associated with a rheumatic affection. These facts are discussed in the light of the data published in the literature. The authors conclude that sydenham's chorea and acute rheumatic fever are but two unrelated expressions of a streptococcal infection. Anti-inlammatory treatment with corticoids, therefore, is only indicated in the presence of signs of rheumatic affection.
