Overview
Rheumatic chorea, also known as Sydenham chorea, is a neurological manifestation often associated with rheumatic fever, characterized by involuntary movements primarily affecting the face, limbs, and trunk. It typically occurs in children and adolescents following streptococcal infections 3.Diagnosis
Clinical Presentation: Presence of involuntary movements, emotional lability, and cognitive changes 3.
Laboratory Tests: Elevated antistreptolysin O (ASO) titers and other streptococcal antibodies 3.
Imaging and EEG: Typically normal, though may show nonspecific changes 3.
Autoantibody Screening: ANA screening; however, specificity for chorea is limited without antigen-specificity confirmation 3.Management
Antibiotics: Penicillin or other appropriate antibiotics to eradicate streptococcal infection 3.
Immunomodulatory Therapy: Corticosteroids or immunoglobulins for severe cases 3.
Supportive Care: Symptomatic management including psychological support and educational accommodations 3.Special Populations
Pediatrics: Commonly affects children and adolescents; management focuses on supportive care and addressing educational needs 3.
Comorbidities: No specific guidance provided in abstracts; management should consider underlying systemic autoimmune conditions and their treatments 2.Key Recommendations
Screen for Streptococcal Infection: Regular monitoring of streptococcal antibodies (e.g., ASO titers) in suspected cases 3.
Initiate Antibiotic Therapy: Early treatment with appropriate antibiotics to prevent complications 3.
Consider Immunomodulatory Support: Use corticosteroids or immunoglobulins for severe neurological manifestations 3 (Evidence: Expert opinion).
Monitor for Secondary Hypogammaglobulinemia: Regular immunoglobulin levels in patients on immunosuppressive therapy, though specific to broader SARDs context 2 (Evidence: Moderate).References
