A Study of Ustekinumab in Participants With Takayasu Arteritis (TAK)
Takayasu ArteritisThe purpose of this study is to evaluate the efficacy of ustekinumab compared to placebo, in combination with oral glucocorticoid (GC) taper regimen, in participants with relapsing Takayasu Arteritis (TAK).
Induction of Regulatory t Cells by Low Dose il2 in Autoimmune and Inflammatory Diseases
Rheumatoid ArthritisAnkylosing Spondylitis12 moreTRANSREG will assess the safety and biological efficacy of low-dose IL2 as a Treg inducer in a set of 14 autoimmune and auto-inflammatory diseases, with the aim to select diseases in which further therapeutic development will be performed. Extensive biological- and immune-monitoring pre- and post-IL2 will contribute (i) to define the common or distinct processes responsible for the breakdown of immunological tolerance in these pathologies and (ii) to discover potential biomarkers of the IL2 response.
Abatacept for Treating Adults With Giant Cell Arteritis and Takayasu's Arteritis
Takayasu's ArteritisGiant Cell ArteritisGiant cell arteritis (GCA) and Takayasu's arteritis (TAK) are diseases that cause swelling of the arteries in the head, neck, upper body, and arms. TAK specifically affects the aorta, the largest blood vessel in the body, and its branches. Therapies are available to improve the symptoms of GCA and TAK, but relapse often occurs, and better treatments are needed. Abatacept is a drug that interacts with certain cells in the body that are involved with GCA and TAK. This study will evaluate the effectiveness of abatacept in treating GCA and TAK and preventing disease relapse.
Comparison of Mycophenolate Mofetil and Cyclophosphamide for Active Takayasu's Arteritis
Takayasu ArteritisTakayasu's arteritis(TAK) is a rare systemic vasculitis which can cause ischemia or inflammation of the involved organs and increase the overall mortality rate.The traditional treatment of TAK is primarily empirical. The most commonly used drugs for treating active TAK are glucocorticosteroids(GC) and immunosuppressants. However, the genital toxicity of CYC has limited its long term use. In a pilot study carried out by the principal investigator of this study has shown that mycophenolate mofetil(MMF) combined with MTX is effective and with few adverse effects. The purpose of this prospective open-label study is to compare the efficacy and safety of GC+MMF+MTX with GC+CYC followed by GC+AZA for the treatment of active TAK. 150 patients with active TAK will be recruited and randomized in a 2:1 ratio to GC+MMF+MTX group and C+CYC and AZA group. Patients were followed for 52 weeks for efficacy and safety assessment.
Efficacy and Tolerance of Tocilizumab In Takayasu Arteritis
TAKAYASU ARTERITISFirst-line tocilizumab treatment during 6 months could permit rapid steroid-tapering and induction of remission in Takayasu arteritis (TA).
PET Imaging of Giant Cell and Takayasu Arteritis
Giant Cell ArteritisTakayasu ArteritisWhile 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) imaging is often included in the diagnostic work-up of patients with large-vessel vasculitis (LVV), 18F-FDG lacks specificity for inflammatory cells and has limited ability to track therapy response. Moreover, high background 18F-FDG uptake in the brain and myocardium largely precludes imaging temporal arteritis in giant-cell arteritis (GCA) and coronary artery involvement in Takayasu arteritis respectively. These limitations of 18F-FDG for imaging LVV highlight important unmet clinical needs, which might be overcome by using a somatostatin receptor subtype-2 (SST2) PET tracer.
Yellow Fever Vaccine in Patients With Rheumatic Diseases
Systemic LupusRheumatoid Arthritis9 moreAccording 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.
Aerobic Capacity and Strength Exercise in Takayasu's Arteritis
Physical ActivityTakayasu ArteritisTakayasu's arteritis is a primary systemic vasculitis that affects large vessels and their main branches. The objectives of the present study were to assess: a) the aerobic capacity (CA); b) security of the acute strength exercise session; c) correlation between CA, as well as strength exercise session, with demographic, clinical, therapeutic, comorbid parameters, and presence and degree of vascular damage; d) serum levels of the cytokines
Exercise in Juvenile Takayasu Disease
Takayasu's ArteritisJuvenile Takayasu disease is characterized by chronic inflammation that leads to vascular disease. Exercise may render anti-inflammatory effects and protect against cardiovascular events. This trial aims to investigate the therapeutic role of exercise in juvenile Takayasu disease.
