to collect data on children with ARF across Australia. Children up to 15 years of age were included if they had an ARF episode diagnosed between October 1, 2007 and December 31, 2010 that met the case definition.ARF was identified in 151 children: 131 Indigenous Australians, 10 non-Indigenous Australians, 8 Pacific Islanders and 1 African (1 unknown). Common presenting features were joint symptoms, fever and carditis. Sydenhamchorea was reported in 19% of children. Aseptic monoarthritis was a major
Movement disorders in autoimmune diseases. Movement disorders have been known to be associated with a variety of autoimmune diseases, including Sydenham'schorea, pediatric autoimmune neuropsychiatric disorders associated with streptococcus, systemic lupus erythematosus, antiphospholipid syndrome, gluten sensitivity, paraneoplastic and autoimmune encephalopathies. Tremors, dystonia, chorea, ballism, myoclonus, parkinsonism, and ataxia may be the initial and even the only presentation
and cardiac myosin and its peptides appear during progression of rheumatic heart disease. However, autoantibodies against collagen that are not crossreactive may form because of the release of collagen from damaged valve or to responses to collagen bound in vitro by certain serotypes of streptococci. In Sydenhamchorea, human mAbs derived from disease target the group A carbohydrate epitope GlcNAc and gangliosides and dopamine receptors found on the surface of neuronal cells in the brain. Human mAbs (...) and autoantibodies in Sydenhamchorea were found to signal neuronal cells and activate calcium calmodulin-dependent protein kinase II (CaMKII) in neuronal cells and recognize the intracellular protein biomarker tubulin.To summarize, pathogenic mechanisms of crossreactive autoantibodies which target the valve in rheumatic heart disease and the neuronal cell in Sydenhamchorea share a common streptococcal epitope GlcNAc and target intracellular biomarkers of disease including cardiac myosin in the myocardium
Anti-streptococcal antibodies reacting with brain tissue. I. Immunofluourescent studies. Serum JD from a 14-year old girl with Sydenhamschorea contained antibodies which gave immunofluorescent staining of the limiting membrane of the brain, ependymal tissue and fibrous astrocytes. These antibodies could be completely absorbed by Str. pyogenes type 24 (NCTC 8305) but only partially if at all by type 6 matt (NCTC 8302) or type 6 glossy (NCTC 8709). In contrast, staining by the same serum (...) reactions of 3/74 could be absorbed out by Str. pyogenes type 24 but not by Str. pyogenes type 6 matt or type 6 glossy. None of these staining patterns given by serum JD or by 3/74 could be absorbed by human uterine smooth muscle. Serum 3/74 stained heart muscle but this reaction could be absorbed without affecting the brain staining reactions. Sera from 4 other patients with Sydenham'schorea were found to give staining of the ependyma and the limiting membrane, 2 only very weakly.
Anti-streptococcal antibodies reacting with brain tissue. II. Utrastructural studies. The reaction of rabbit anti-Streptococcus pyogenes type 24 with mouse brain has been studied at the ultrastructural level using horseradish peroxidase labelled antiglobulin. It is shown that these antibodies, and by inference those found in Sydenham'schorea, react with the fibrous astrocyte. The cross-reacting antigen is the glial filament or a closely associated cytoplasmic constituent.
Involuntary movements in patients taking oral contraceptives Involuntary movements developed in five women taking oral contraceptives. In one, the sudden onset of a unilateral disturbance suggested a cerebral thrombosis; this case is considered to be a further example of the increased risk of cerebrovascular disease associated with oral contraception. The four other patients suffered a relapse of Sydenham'schorea between one and four months after starting an oral contraceptive regimen
equally elevated and were significantly higher than the normal controls. When Group A antibody levels were determined on sera obtained at intervals of 5-12 months and 1-5 yr after the acute illness) it was found that the antibody levels declined within the normal range at the 5-12 month interval in patients with glomerulonephritis as well as in patients with rheumatic fever in whom no valvular involvement had complicated the disease, i.e., patients with pure Sydenham'schorea. However, in patients (...) with rheumatic valvulitis, who had been on penicillin prophylaxis after the last acute episode, the A antibody level showed little decline from the level obtained during the acute illness. The elevated antibody level in patients with rheumatic valvulitis, including patients with Sydenham'schorea with valvulitis, persisted for periods of at least 1 yr and up to 20 yr after the last acute attack. The pattern of the decline of the antibody levels to the A-variant carbohydrate as well as of the antibody titers
, based on one Class I study (Level B). Plasmapheresis is possibly effective and may be considered for acute fulminant demyelinating CNS disease (Level C). There is insufficient evidence to support or refute the use of plasmapheresis for myasthenia gravis, pediatric autoimmune neuropsychiatric disorders associated with streptococcus infection, and Sydenhamchorea (Class III evidence, Level U).
. Perivascular neutrophilic and mononuclear infiltrates of the dermis occur. CNS Sydenhamchorea, the form of chorea that occurs with ARF, manifests in the CNS as hyperperfusion and increased metabolism in the basal ganglia. Increased levels of antineuronal antibodies have also been shown. Symptoms and Signs An initial episode of symptoms of rheumatic fever occurs typically about 2 to 3 wk after the streptococcal infection. Manifestations typically involve some combination of the joints, heart, skin, and CNS (...) . It sometimes lasts < 1 day. Its appearance is often delayed after the inciting streptococcal infection; it may appear with or after the other manifestations of rheumatic inflammation. CNS Sydenhamchorea occurs in about 10 to 30% of children. It may develop along with other manifestations but frequently arises after the other manifestations have subsided (often months after the acute streptococcal infection) and thus may be overlooked as an indicator of acute rheumatic fever. Onset of chorea is typically

ataxia and pesudoathetosis. Other disorders such as Sydenham'schorea, or chorea related to systemic lupus erythematosus and antiphospholipid syndrome occur in association with multiple antibodies, are not paraneoplastic, and are triggered by molecular mimicry or unknown mechanisms. Recent studies have revealed a new category of disorders that can be paraneoplastic or not, and associate with antibodies against cell-surface or synaptic proteins. They include anti-N-methyl-D-aspartate receptor (anti (...) Movement disorders in paraneoplastic and autoimmune disease The most relevant advances in immune-mediated movement disorders are described, with emphasis on the clinical--immunological associations, novel antigens, and treatment.Many movement disorders previously considered idiopathic or degenerative are now recognized as immune-mediated. Some disorders are paraneoplastic, such as anti-CRMP5-associated chorea, anti-Ma2 hypokinesis and rigidity, anti-Yo cerebellar ataxia and tremor, and anti-Hu

An April 2013 review article in the Indian Journal of Medical Research stated that echocardiographic and Doppler (E & D) studies, despite some reservations about their utility, have identified a massive burden of rheumatic heart disease, which suggests the inadequacy of the 1992 Jones' criteria. E & D studies have identified subclinical carditis in patients with rheumatic fever, as well as in follow-ups of rheumatic heart disease patients who initially presented as having isolated cases of Sydenham's (...) chorea.

interest has been Group A Streptococcus (GAS), which began to receive attention as a potential cause of neuropsychiatric symptoms, following the investigation of the symptoms reported in Sydenham'schorea (SC) and rheumatic fever, such as motor tics, vocal tics, and both obsessive-compulsive and attention deficit/hyperactivity symptoms. Young children have been described as having a sudden onset of these neuropsychiatric symptoms temporally associated with GAS, but without supporting evidence (...) and MedLine databases using the following keywords: OCD, immune, PANDAS, Sydenhamchorea, Tourette's disorder Group A Streptococcus. Articles were also identified through reference lists from research articles and other materials on childhood OCD, PANDAS, and TD between 1966 and December 2010. Considering the overlap of clinical and neuroanatomic findings among these disorders, this review explores evidence regarding the immunobiology as well as the relevant clinical and therapeutic aspects of TD, OCD
