Active clinical trials for "Dermatomyositis"

This is a phase 2, single-center study in patients with active cutaneous DM who have had an inadequate response. An inadequate response is defined as no improvement with standard of care treatment based on the investigator's opinion. All subjects will initially receive baricitinib 2mg daily for 8 weeks. If no unexpected serious adverse events related to baricitinib have occurred during the first 8 weeks of treatment in the opinion of the investigator, the dose will be increased to 4 mg daily for 16 weeks. Visits are scheduled at baseline, 4 weeks, 8 weeks, 12 weeks, 16 weeks, 20 weeks, and 24 weeks. Evaluation of primary endpoint occurs at week 24. All subjects receive a phone call from study

In the Netherlands, the human Papillomavirus (HPV) vaccination will be added to the National Vaccination Program for girls to protect against the development of cervical cancer. The vaccine protects against HPV type 16 & 18, which cause about 75% of cervical cancer. Studies have shown that the vaccine is effective in healthy subjects in preventing infection by HPV 16 & 18. However, no evidence exists on the immunogenicity and safety of HPV vaccination in patients with an immune system disorder, such as primary humoral immunodeficiency (i.e. hypogammaglobulinemia) or autoimmune diseases. Concerns exist that vaccination may cause an aggravation of the underlying disease. In addition, the immune response to vaccination may be diminished due to immunosuppressive therapy or the underlying disease. Objective: The primary goal of the current study is to study the immunogenicity of HPV vaccination in patients with an autoimmune disease and a primary humoral immunodeficiency. Based on retrospective analysis with other vaccines we hypothesize that patients with autoimmune diseases who are under immunosuppressive medication and patients with a immune system disorder have a decreased serological response to HPV vaccination, and that the produced HPV antibodies titers decrease more rapidly than in healthy individuals. The secondary objective is to explore safety of HPV vaccination and immune regulatory mechanisms induced by vaccination in a subset of patients. The investigators hypothesize that HPV vaccination is safe and that HPV-induced regulatory T cells are able to prevent an increase in the activity of an autoimmune disease.

The purpose of this study is to evaluate denosumab as a novel treatment for bone loss in children treated with glucocorticoids for rheumatic disorders. This is a pilot Phase 1/2, randomized open-label, 12-month clinical trial of denosumab to assess its effect on bone resorption markers and bone mineral density (BMD) in children with rheumatic disorders, age 4 to 16 years, recruited within 1 month of starting a chronic systemic glucocorticoid regimen. Primary outcomes include suppression of bone turnover markers and safety assessments. Secondary outcomes include changes in bone density as measured by dual energy X-ray absorptiometry (DXA) and peripheral quantitative computed tomography (pQCT) densitometry at the radius and tibia.

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.

This study is a Proof of Concept study aiming to evaluate the production of anti-IFNα antibodies (immune response) in adult subjects with dermatomyositis

Dermatomyositis (DM) are rare and heterogeneous systemic autoimmune diseases, characterized by the association of muscle inflammation, skin inflammation and vasculopathy. DM concern both adults and children. DM can be life-threatening (interstitial lung disease, infectious complications) and responsible of significant functional disability (muscle weakness). Age of onset appear to be an independent prognostic factor. Juvenile-onset DM is characterized by a higher frequency of calcinosis, skin ulceration and digestive vasculitis. In adults, interstitial lung disease and cancer are more frequent with higher mortality. Data concerning the comparison of the initial severity between juvenile and adult-onset DM are limited. The main objective is to compare global severity between juvenile DM and adult-onset DM at initial diagnosis. Secondary objectives are: to compare organ-specific severity between juvenile DM and adult-onset DM at diagnosis. to compare damage during follow-up and at last follow-up between juvenile DM and adult-onset DM. to compare activity at the last follow-up between juvenile DM and adult-onset DM. to compare iatrogenic complications between juvenile DM and adult-onset DM.

evaluation of level of serum circulating plexin D1 on extacellular vesicles in adult PM/DM patients and juvenile dermatomysitis.

This project will bring together a multidisciplinary team of pediatric rheumatologists, neurologists, metabolic geneticists and exercise physiologists to determine the effect of creatine (CR) supplementation on muscle function and muscle metabolism in children with Dermatomyositis (DM). The investigators propose using well-established exercise testing techniques as well as new, powerful exercise imaging protocols in order to better delineate the effects of CR on muscle pathophysiology in a non-invasive way. Evidence from this study will provide information regarding the effect of creatine supplementation on muscle function in DM. Improvements in muscle function and fatigue through CR use may also contribute to an improvement in quality of life and have significant clinical implications for the treatment of children with DM.

Polymyositis and dermatomyositis are rare inflammatory systemic conditions. Reduced muscle function is a cardinal symptom and lung involvement is very common. Knowledge of heart involvement in these patients is very limited, as is knowledge of exercise effects in recent onset, active disease. The aim of this project is to investigate effects of high-intensity interval training (HIIT) compared to standard low-intensity home exercise as to tolerance, physical capacity, quality of life, depression, disease activity, inflammation, muscle mass/fat mass, muscle metabolism and heart function in patients with recent onset, active polymyositis and dermatomyositis. This is a randomized controlled trial. Muscle biopsies are taken at time of diagnosis and after 12 weeks of exercise. Muscle biopsies will be analyzed as to baseline kynurenine pathway, calcium release, gene expression and inflammatory infiltrates and as to changes in these parameters following exercise. Muscle function (primary outcome), maximal oxygen uptake, muscle mass/fat mass, disease activity, systolic and diastolic heart function, as well as quality of life and depression is measured at baseline and after 12 weeks of exercise. After all assessments, patients are randomized to HIIT or standard low-intensity home exercise. The HIIT group will perform 6 sets of 30-60 second biking bouts reaching 85-100% of maximal heart rate, in combination with strength training, three days a week for 12 weeks. The control group will perform a standardized home exercise program five days a week for 12 weeks. After 12 weeks, all assessments are preformed again. If the HIIT is well tolerated, patients in the control group will be invited to HIIT exercise according to the same protocol. Clinical assessments will be performed at 3, 6 and 9 months follow-up in an open extension. This study will improve our understanding of heart function, muscle metabolism as well as tolerance and effects of intensive exercise as well as heart function early in the disease course and could also improve treatment and prognosis in patients with polymyositis and dermatomyositis.
