Management, treatment, and clinical approach of Sydenham's chorea in children: Italian survey on expert-based experience.

Sydenham's chorea (SC), an autoimmune disorder affecting the central nervous system, is a pivotal diagnostic criterion for acute rheumatic fever. Primarily prevalent in childhood, especially in developing countries, SC manifests with involuntary movements and neuropsychiatric symptoms. Predominantly occurring between ages 5 and 15, with a female bias, SC may recur, particularly during pregnancy or estrogen use. The autoimmune response affecting the basal ganglia, notably against dopamine, underlies the pathophysiology. Clinical management necessitates an integrated approach, potentially involving immunomodulatory therapies. To address discrepancies in SC management, a survey was conducted across Italy, targeting specialists in neurology, pediatrics, child neuropsychiatry, and rheumatology. Of the 51 responding physicians, consensus favored hospitalization for suspected SC, with broad support for laboratory tests and brain MRI. Treatment preferences showed agreement on oral prednisone and IVIG, while opinions varied on duration and plasmapheresis. Haloperidol emerged as the preferred symptomatic therapy. Post-SC penicillin prophylaxis and steroid therapy gained strong support, although opinions differed on duration. Follow-up recommendations included neuropsychological and cardiological assessments. Despite offering valuable insights, broader and more studies are needed in order to guide treatment decisions in this well-known yet challenging complication of acute rheumatic fever, which continues to warrant scientific attention and concerted clinical efforts.
