Filter by:According to World Health Organization (WHO), since December 2016, Brazil is showing a significant increase in cases of yellow fever in humans. In view of this, vaccination is suitable for residents and travelers to the risk area. However, for immunosuppressed patients there is a formal recommendation not to vaccinate with live virus vaccine. On the other hand, the safety and efficacy of the vaccine has been demonstrated in patients with HIV, and safety and seroconversion have also been demonstrated in patients with rheumatic disease who were inadvertently revaccinated for yellow fever. Faced with the impossibility of leaving the high-risk area for some patients the vaccination could be released to only those who have low level of immunosuppression as suggested by some recommendations of medical societies. The availability of a fractional vaccine in the State of São Paulo, which has proved its efficacy, opens the possibility of exposure to a lower number of copies of the virus in the first exposure of immunosuppressed patients, allowing, if necessary, a safer revaccination, after 28 days to obtain of a more effective immunogenic response. The objectives of the study are to evaluate the immune response of the immunization with fractional yellow fever vaccine (neutralizing antibodies) in patients with systemic autoimmune rheumatic diseases residing in a high-risk area. Secondarily, evaluate the possible association between immunogenicity and vaccination with: demographic data, clinical and laboratory activity of the disease in patients with chronic rheumatic diseases, evaluate the curve of viremia and report adverse events. Patients and healthy controls will be vaccinated for yellow fever in the Immunization Center of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC-FMUSP). The patients' screening for exclusion and inclusion criteria will be done at the rheumatology outpatient clinic after medical evaluation. For the controls will be the routine screening of the Immunization Center. The vaccination protocol will be a fractional dose of the yellow fever vaccine on day D0 for both groups. Patients will be evaluated on day D0, D5, D10, D30-4 and D365 and controls only on days D0, D10, D30-45 and D365 for aspartate aminotransferase (AST), alanine aminotransferase (ALT), platelets, urea and creatinine, immunoglobulin M (IgM) by immunofluorescence for Yellow Fever, viremia, autoantibodies.
Comparing the clinical effects of Acthar Gel before and after treatment and compare it to patients with inactive disease.
Soccer is an intermittent sport including a high number of powerful actions such as accelerations, decelerations, changes of direction, jumps and impacts that incorporate a strong eccentric component and may therefore lead to skeletal muscle damage. Indeed, match activity is associated with the onset of muscle damage and an acute inflammatory response that result in attenuated performance for as long as 1 to 3 days. In competitive soccer though, multiple matches are performed within a small-time frame resulting in inadequate muscle recovery and reduced field performance. Supplementation with milk proteins following intense exercise protocols has been shown to stimulate protein synthesis and facilitate muscle recovery. Thus, the aim of the present investigation is to examine the effects of milk protein supplementation on muscle recovery and soccer-specific performance during an in-season microcycle with two matches performed three days apart.
The study aimed to assess the safety and, partially, the efficacy of dietary supplementation of a flavonoids-, DHA- and EPA-based natural supplement in non-ambulant DMD boys and in a cohort of LGMD and FSHD patients to compare its effect in MDs of different aetiology and to eventually highlight any differences in inflammatory involved pathways. To assess safety, patient's laboratory parameters were monitored and adverse events recorded, while efficacy was evaluated through performance scale questionnaire and strength measurement (6 minute walking test and Biodex System 4 Dynamometer parameter evaluation). This study was conceived as proof of principle for the safe use of flavonoids/omega3s-based compound as an adjuvant in the management of neuromuscular disorders; besides, its efficacy in alleviating symptoms linked to secondary effects of genetic mutation as inflammation, muscular pain and weakness was assessed.
This study aims at assessing the gene expression in the muscles of patients suffering from sporadic Inclusion Body Myositis (sIBM) at various stages of the disease, by comparison with muscles of control subject. The investigators use the RNA-seq technique to analyze the gene expression levels and potential alternate transcripts, including long non-coding RNAs (lncRNAs), in muscle tissue samples. The gene expression profiles will point to the genes of interest that can then become the object of future studies, in which epigenetic changes of these genes will be explored further. The value of those possible biomarkers will be assessed. The investigators will also evaluate the correlation between the gene expression profile, the degree of functional impairment, the histological picture and the presence or absence of autoantibodies.
Background: Dermatomyositis (DM) and juvenile dermatomyositis (JDM) cause inflammation in the muscles. People with DM and JDM can develop calcium deposits in places they should not, known as calcinosis. Calcinosis can be painful and cause disabilities and other problems. Researchers want to learn more about calcinosis to find treatments for it. Objective: To test if sodium thiosulfate (STS) can treat people with DM with calcinosis. Eligibility: People ages 7 and older who have moderate or severe calcinosis. They must have stable DM and calcium deposits in the torso or at least 2 limbs. Design: Participants will be screened with: - Medical history - Physical exam - Muscle strength and function tests - Blood and urine tests Participants will have several visits: - 7-day pre-treatment visit about 10 weeks before starting STS - Treatment visits over 10 weeks. They will get STS 3 times a week through IV infusion. They may be hospitalized the whole time. If they tolerate the drug, they may be discharged at certain times. During these times, they will return for the infusions. - 3- to 5-day post-treatment visits 24 weeks and 62 weeks after starting STS. Visits may include repeats of screening tests and: - Questionnaires - Scans: They lie in a machine that takes pictures of the body. They may be injected with a radioactive agent. - Durometry: A small instrument applies pressure on the skin or exposed calcinosis. - Measurements of blood flow in the arms and fingernail blood vessels - Photographs of the skin - Kidney ultrasound - Tests of kidney function - Calcinosis aspiration: A needle placed into areas of calcinosis removes liquid.
Physical training may improve physical capacity and health parameters in various systemic autoimmune diseases, including idiopathic inflammatory myopathies. Therefore, the present study will assess the role of an exercise training program in patients with idiopathic inflammatory myopathies.
The aim of the study is to evaluate the psychometric properties (content and construct validity, reliability, measurements error, as well as possible floor and ceiling effects) of both the assessments MMT8 and the myositis activity profile in patients with IM.
The purpose of this study was to determine whether moderate-severe endpoints (including high fever, lower respiratory tract disease, acute otitis media, or serious extra-pulmonary complications) were predictive of hospitalization, intensive care admission, antibiotic use and other complications in children under 8 years of age.
