Abstract
Importance Sydenham chorea is the most common acquired chorea of childhood worldwide; however, treatment is limited by a lack of high-quality evidence. Objectives To evaluate historical changes in the clinical characteristics of Sydenham chorea and identify clinical and treatment factors at disease onset associated with chorea duration, relapsing disease course, and functional outcome. Data Sources The systematic search for this meta-analysis was conducted in PubMed, Embase, CINAHL, Cochrane Library, and LILACS databases and registers of clinical trials from inception to November 1, 2022 (search terms: [Sydenham OR Sydenham's OR rheumatic OR minor] AND chorea). Study Selection Published articles that included patients with a final diagnosis of Sydenham chorea (in selected languages). Data Extraction and Synthesis This study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Individual patient data on clinical characteristics, treatments, chorea duration, relapse, and final outcome were extracted. Data from patients in the modern era (1945 through 2022) were entered into multivariable models and stratified by corticosteroid duration for survival analysis of chorea duration. Main Outcomes and Measures The planned study outcomes were chorea duration at onset, monophasic course (absence of relapse after ≥24 months), and functional outcome (poor: modified Rankin Scale score 2-6 or persisting chorea, psychiatric, or behavioral symptoms at final follow-up after ≥6 months; good: modified Rankin Scale score 0-1 and no chorea, psychiatric, or behavioral symptoms at final follow-up). Results In total, 1479 patients were included (from 307 articles), 1325 since 1945 (median [IQR] age at onset, 10 [8-13] years; 875 of 1272 female [68.8%]). Immunotherapy was associated with shorter chorea duration (hazard ratio for chorea resolution, 1.51 [95% CI, 1.05-2.19]; P = .03). The median chorea duration in patients receiving 1 or more months of corticosteroids was 1.2 months (95% CI, 1.2-2.0) vs 2.8 months (95% CI, 2.0-3.0) for patients receiving none (P = .004). Treatment factors associated with monophasic disease course were antibiotics (odds ratio [OR] for relapse, 0.28 [95% CI, 0.09-0.85]; P = .02), corticosteroids (OR, 0.32 [95% CI, 0.15-0.67]; P = .003), and sodium valproate (OR, 0.33 [95% CI, 0.15-0.71]; P = .004). Patients receiving at least 1 month of corticosteroids had significantly lower odds of relapsing course (OR, 0.10 [95% CI, 0.04-0.25]; P < .001). No treatment factor was associated with good functional outcome. Conclusions and Relevance In this meta-analysis of treatments and outcomes in patients with Sydenham chorea, immunotherapy, in particular corticosteroid treatment, was associated with faster resolution of chorea. Antibiotics, corticosteroids and sodium valproate were associated with a monophasic disease course. This synthesis of retrospective data should support the development of evidence-based treatment guidelines for patients with Sydenham chorea.

Abstract
Postinfectious neuroinflammation has been implicated in multiple models of acute-onset obsessive-compulsive disorder including Sydenham chorea (SC), pediatric acute-onset neuropsychiatric syndrome (PANS), and pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection (PANDAS). These conditions are associated with a range of autoantibodies which are thought to be triggered by infections, most notably group A streptococci (GAS). Based on animal models using huma sera, these autoantibodies are thought to cross-react with neural antigens in the basal ganglia and modulate neuronal activity and behavior. As is true for many childhood neuroinflammatory diseases and rheumatological diseases, SC, PANS, and PANDAS lack clinically available, rigorous diagnostic biomarkers and randomized clinical trials. In this review article, we outline the accumulating evidence supporting the role neuroinflammation plays in these disorders. We describe work with animal models including patient-derived anti-neuronal autoantibodies, and we outline imaging studies that show alterations in the basal ganglia. In addition, we present research on metabolites, which are helpful in deciphering functional phenotypes, and on the implication of sleep in these disorders. Finally, we encourage future researchers to collaborate across medical specialties (e.g., pediatrics, psychiatry, rheumatology, immunology, and infectious disease) in order to further research on clinical syndromes presenting with neuropsychiatric manifestations.

Abstract
OBJECTIVE An association between streptococcal infections, ABGA positivity, and no comorbidity ADHD (nc-ADHD) has been little investigated. The aim of this study was to evaluate the streptococcal infection frequency, defined entitled serum antistreptolysin O (ASO), and frequency of serum ABGA positivity in a sample of patients with nc-ADHD. METHOD In all 40 participants were investigated the ASO titer and ABGA. RESULTS The results showed that ABGA positivity was statistically significantly higher in patients affected by ADHD than in patients of a control group, and pathological values of ASO were statistically more frequent in the ADHD group than the control group. CONCLUSION These data suggest that streptococcal infections and autoimmune reactions against the basal ganglia are more frequent in ADHD patients than patients in a control group.

Abstract
Infections, and the resulting immune response to these infections, have recently received increased recognition as pathogenic mechanisms for neuropsychiatric disorders. Sydenham's chorea (SC), a widely recognized post-streptococcal autoimmune disorder, represents a model for this proposed pathogenesis. In SC, a dysregulated immune response to a streptococcal infection is hypothesized to result in inflammation of neuronal networks, particularly the basal ganglia nuclei. The resulting dysfunction in the basal ganglia nuclei are hypothesized to lead to a constellation of adventitious movements and psychiatric symptoms, which investigations have shown are amenable to immunomodulatory therapies. PANDAS (Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal infections) has been proposed as a variant of SC, and is hypothesized to share a pathogenic mechanism, despite a unique symptom profile of predominantly psychiatric symptoms. In this review, we present the clinical aspects of both disorders, the data for potential shared etiopathogenesis between them, and the evidence for the therapeutic use of immunomodulatory therapies for the symptoms of SC and PANDAS. This article is part of a Special Issue entitled SI: Neuroimmunology in Health And Disease.

Abstract
Attention deficit/hyperactivity disorder (ADHD) is often present in patients with post-streptococcal neuropsychiatric disorders such as Sydenham's chorea and PANDAS, in which anti-basal ganglia antibodies (ABGA) have been frequently found. Our study investigates the hypothesis that pharyngeal group A beta-hemolytic streptococcus (GABHS) infections and serum ABGA are more frequent in children with ADHD non-comorbid (nc-ADHD) with obsessive-compulsive disorder or tics than in controls. We compared 22 children with nc-ADHD (DSM-IV-TR) and 22 healthy controls matched by age, gender and season of sample collection, for the frequency of recent GABHS infection and the presence of ABGA. Eleven out of 22 children (51%) with nc-ADHD showed evidence of GABHS infection compared to three out of 22 (14%) controls (P = 0.007). We found positive ABGA in one ADHD subject (4%) and in one control (4%). This preliminary study indicates that frequency of ABGA in children with nc-ADHD does not differ from that in matched controls, despite the fact that our ADHD patients had had more recent GABHS infections than the controls. This suggests that ABGA do not have a role in the pathogenesis of nc-ADHD.

Abstract
The well-known symptoms of rheumatic fever and Sydenham's chorea are briefly discussed. Then the associated psychiatric and neurological disorders are considered, especially the obsessive-compulsive and the attention deficit hyperactivity disorders; all linked to previous haemolytic streptococcal infections. Dystonic syndromes, and acute disseminated encephalopathies, also show such links; and may be part of the clinical spectrum of the post-infectious streptococcal illnesses. The causes of Sydenham's chorea are considered, especially an immune reactivity against the basal ganglia, supported by the finding of antibodies reactive against the neurons of the caudate nucleus. The resulting imbalance between dopaminergic and cholinergic systems may cause the involuntary choreiform movements, and account for the beneficial effects of certain drugs. The differential diagnosis of Sydenham's chorea is discussed, and the role of tests such as special imaging techniques. The possible treatments include prophylaxis with penicillin and the use of drugs like sodium valproate, carbamazapine and haloperidol. Immune therapy occupies a special role in selected patients, There is still a need for research into the links between these conditions.

Abstract
PURPOSE OF REVIEW Pediatric movement disorders the represent a broad range of disorders, the majority of which are intermittent and hyperkinetic. The goal of this review is to discuss recent findings in several under-recognized conditions (motor stereotypy disorder, restless legs syndrome, and infantile masturbation) as well as the area of autoimmune movement disorders [Sydenham's chorea and PANDAS (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection)]. RECENT FINDINGS Advances to be discussed include clarification of symptoms, diagnostic clues, epidemiology, pathogenesis, and treatment. SUMMARY Significant progress has been made in the study of several paroxysmal movement disorders. Motor stereotypies can occur in typical children and persist over time. Infantile masturbation is often misdiagnosed for seizures or dystonia. Restless leg syndrome is a relatively common problem in children and established criteria are available. Advances have been made in the hallmark autoimmune disorder Sydenham's chorea, but PANDAS remains controversial.

Abstract
The anterior cingulate cortex (ACC) plays a major role in modulating executive control of attention. Here, 15 medication-nai ve patients with attention deficit/hyperactivity disorder (ADHD) and 10 carefully matched healthy controls were studied with 2D (1)H-magnetic resonance spectroscopic imaging (MRSI) of the ACC [Brodmann areas 24b'-c' and 32']. Attentional skills were assessed using the identical pairs version of the continuous performance task (CPT-IP). Analysis of regional brain spectra revealed a significantly increased signal of choline-containing compounds (Ch) in the ACC of ADHD patients (p<0.05). Across and within groups, the Ch signal showed high correlations with slowed hit reaction times on the CPT-IP. No group differences in N-acetyl-aspartate (NAA) and creatine (tCr) were detectable. The combination of performance deficits and elevated Ch levels in the ACC supports the hypothesis that subtle structural abnormalities underlie the functional alterations in ACC activation previously observed in ADHD patients.
