Purpose: Sydenham chorea is known for its rapid, irregular, and aimless involuntary movements and is considered a benign and self-limiting condition among the major manifestations of rheumatic fever. The current study reviewed the demographic, clinical, and paraclinical findings of pediatric patients with Sydenham chorea.
Methods: This cross-sectional study was conducted among 22 patients with Sydenham chorea who were admitted to the pediatric wards of Mashhad Imam Reza and Ghaem Hospitals between 2006 and 2016. Data from these patients’ medical records were extracted, organized using checklist forms, and analyzed.
Results: Eight patients were male and 14 were female. The average age was 10.09±3.53 years. In 31.8% of patients, chorea was the only sign of rheumatic fever. Chorea was unilateral in 21.1% of patients. The most common clinical findings were, in descending order, jerky movements, facial grimacing, gait disorders, mental disorders, speech disorders, muscle weakness, and milkmaid’s grip. Cardiac auscultation was normal in 76.2% of patients, while a holosystolic murmur was heard in 23.8%. In laboratory exams, 50% of patients were erythrocyte sedimentation rate (ESR)-positive, 31.2% were C-reactive protein (CRP)-positive, and 53.3% were anti-streptolysin O (ASO)-positive. Echocardiography showed the prevalence of mitral regurgitation (63.6%), aortic regurgitation (45.5%), tricuspid regurgitation (22.7%), pulmonary regurgitation (4.5%), and pericardial effusion (4.5%).
Conclusion: This study showed that Sydenham chorea can be the only sign of rheumatic fever. This disease typically occurs in children between the ages of 7 and 12. ESR, CRP, and ASO can be the most effective laboratory tests for diagnosis.
