Abstract Background: This research is recommended by the Myopathy Committee of the Brazilian Society of Rheumatology for the investigation and diagnosis of systemic autoimmune myopathies. Body: A systematic literature review was performed in the Embase, Medline (PubMed) and Cochrane databases, including studies published until October 2018. PRISMA was used for the review, and the articles were evaluated, based on the Oxford levels of evidence. Ten recommendations were developed addressing different aspects of systemic autoimmune myopathy investigation and diagnosis. Conclusions: The European League Against Rheumatism/ American College of Rheumatology (EULAR/ACR) classification stands out for the diagnosis of systemic autoimmune myopathies. Muscular biopsy is essential, aided by muscular magnetic resonance images and electroneuromyography in complementary research. Analysis of the factors related to prognosis with the evaluation of extramuscular manifestations, and comorbidities and intense investigation regarding differential diagnoses are mandatory.

Abstract Background: Recommendations of the Myopathy Committee of the Brazilian Society of Rheumatology for the management and therapy of systemic autoimmune myopathies (SAM). Main body: The review of the literature was done in the search for the Medline (PubMed), Embase and Cochrane databases including studies published until June 2018. The Prisma was used for the systematic review and the articles were evaluated according to the levels of Oxford evidence. Ten recommendations were developed addressing the management and therapy of systemic autoimmune myopathies. Conclusions: Robust data to guide the therapeutic process are scarce. Although not proven effective in controlled clinical trials, glucocorticoid represents first-line drugs in the treatment of SAM. Intravenous immunoglobulin is considered in induction for refractory cases of SAM or when immunosuppressive drugs are contra-indicated. Consideration should be given to the early introduction of immunosuppressive drugs. There is no specific period determined for the suspension of glucocorticoid and immunosuppressive drugs when individually evaluating patients with SAM. A key component for treatment in an early rehabilitation program is the inclusion of strengthbuilding and aerobic exercises, in addition to a rigorous evaluation of these activities for remission of disease and the education of the patient and his/her caregivers.

Resumo A esclerose sistêmica (ES) é uma doença autoimune crônica de alta morbimortalidade. Ainda que a ciclofosfamida seja eficaz, para casos graves e refratários há demanda para novos tratamentos. A terapia biológica com depleção de células B com rituximabe (RTX) demonstrou eficácia para tal demanda em estudos abertos. Objetivo Avaliar retrospectivamente todos os pacientes que fizeram uso do RTX para tratamento de ES em nosso centro. Pacientes e métodos Foram avaliados retrospectivamente todos os prontuários de pacientes com ES que fizeram uso de RTX para tratamento da ES de janeiro de 2009 a janeiro de 2015. Dados de acometimento sistêmico, cutâneo, pulmonar e laboratoriais antes e seis meses após a primeira infusão de RTX foram coletados. Resultados Dez pacientes receberam o tratamento no período de estudo e foram incluídos na presente série de casos. Todos os pacientes tinham a forma difusa da doença. Cinco pacientes tinham formas iniciais (tempo de doença menor ou igual a quatro anos) e rapidamente progressiva da doença e cinco receberam o RTX em fases tardias da doença. Houve estabilização do quadro pulmonar em ambos os grupos de pacientes e redução no escore cutâneo nos pacientes com formas iniciais da doença. Discussão Similar ao encontrado em estudos prévios, o RTX foi eficaz no tratamento de formas iniciais e rapidamente progressivas da ES. Verificamos também benefício em pacientes com longa duração da doença.

Abstract Systemic sclerosis (SSc) is a chronic autoimmune disease with a high morbidity and mortality. Although cyclophosphamide is effective for severe and refractory cases, there is demand for new treatments. The biological treatment with B-cell depletion with rituximab (RTX) has demonstrated efficacy for this demand in open-label studies. Objective This study was conducted with the aim to retrospectively evaluate all patients who used RTX for the treatment of SSc in our center. Patients and methods We retrospectively evaluated medical records of all patients with SSc who used RTX to treat this disease from January 2009 to January 2015. Systemic, cutaneous, and pulmonary involvement data and laboratory results before and six months after the first infusion of RTX were collected. Results Ten patients received treatment during the study period and were included in this series. All patients had a diffuse form of the disease. Five patients suffered from an early (duration of disease shorter or equal to four years), rapidly progressive disease, and another five received RTX at late stages of the disease. In both groups of patients, stabilization of the pulmonary picture was observed, with a fall in the skin score in those patients with early forms of the disease. Discussion Similar to findings in previous studies, RTX was effective in treating early and rapidly progressive forms of SSc. We also found that patients with long-term illness may benefit from the treatment.

RESUMOAs recomendações propostas pela Comissão de Síndrome de Sjögren da Sociedade Brasileira de Reumatologia para tratamento da síndrome de Sjögren foram baseadas em uma revisão sistemática da literatura nas bases de dados Medline (PubMed) e Cochrane até outubro de 2014 e opinião de especialistas na ausência de artigos sobre o assunto. Foram incluídos 131 artigos classificados de acordo com Oxford & Grade. Essas recomendações foram elaboradas com o objetivo de orientar o manejo adequado e facilitar o acesso aos tratamentos para aqueles pacientes com adequada indicação de recebê-los, considerando o contexto socioeconômico brasileiro e os medicamentos disponíveis no país.

ABSTRACTThe recommendations proposed by the Sjögren's Syndrome Committee of the Brazilian Society of Rheumatology for the treatment of Sjögren's syndrome were based on a systematic review of literature in Medline (PubMed) and the Cochrane databases until October 2014 and on expert opinion in the absence of studies on the subject. 131 articles classified according to Oxford & Grade were included. These recommendations were developed in order to guide the management and facilitate the access to treatment for those patients with an appropriate indication, considering the Brazilian socioeconomic context and pharmacological agents available in this country.
