Acute Rheumatic Fever is an autoimmune inflammatory post-infectious syndrome, mainly caused by type A streptococcus. It is characterized as an inadequate immune response. It may provoke carditis (which associates valvular leakages, cardiac conduction system troubles, and pericardial signs), combined with articular, skin and neurologic signs. Only carditis, prevalent in 60% of acute rheumatic diseases, may provoke valvular sequels, which define rheumatic cardiopathy. Prevalence of acute rheumatic disease (ARD) in pproximately 6 cases per 1000 children in Sub-Saharan Africa countries, whereas prevalence in developed countries is less than a case per 100 000 children, with an annual incidence of 470 000 cases and almost 230 000 deaths annually worldwide. Carditis affect between 15 and 20 million people worldwide, mostly children and young adults from low and middle-income countries. This prevalence may be underestimated. In 2007, our team conducted a study in Mozambique and Cambodia that highlighted that, through a screening based on systematic echocardiography in children from several schools, approximately 2/3 of them had asymptomatic and unknown cardiac lesions, which cannot be screened only with a clinical examination. Role of B-type lymphocytes (B cells) in auto-immune diseases physiopathology is nowadays largely accepted and justifies, in certain auto-immune diseases, the use of therapeutics that target and destroy B cells. Rituximab is a CD-20-specific monoclonal chimeric antibody, indicated to treat B lymphomas, where its efficacy and safety have changed the management of these diseases. Recently, it is thought to use Rituximab in auto-immune diseases. Antibiotherapy based on penicillin is the standard treatment of both acute rheumatic fever and its prevention. Although no anti-inflammatory treatment has proved its efficacy, with or without steroids anti-inflammatory treatments are administered in acute episode of ARF. Up to date, only prevention strategies have shown efficacy.
