Ectopic soft tissue calcifications or ossifications can complicate the course of numerous diseases; most of them are rare or very rare. Even if the clinical, radiological and pathological presentation of ectopic calcifications and ossifications are different, the same hypotheses are discussed considering their hypothetical pathophysiology. Indeed, high calcium phosphate product, local cellular lesions and abnormal transdifferentiation of mesenchymal cells are regularly evoked when pathophysiology of such calcifications or ossifications are discussed. Apart from several case reports that have not been confirmed so far, no medical treatments are available, leading to significant pain and impairment of quality of life for patients. Therefore, only surgical treatment can be proposed when the volume or the consequences of these calcifications/ossifications become too important. Sodium thiosulfate (STS) is currently used as a cyanide poisoning antagonist and a chemoprotectant against adverse effects of several chemotherapies such as Cisplatin. Numerous case reports and several studies have revealed the potential interest of STS in the treatment of uremic induced vascular or soft tissues calcifications. Recently, our group has developed an expertise in the use of STS for the treatment of ectopic soft tissue calcifications or ossifications. Considering these promising preliminary data, and their limits, we developed a strategy to treat soft tissue calcifications or ossifications based on a local administration of STS. The first results of this therapeutic strategy are highly promising and the local or systemic safety is satisfactory so far. These preliminary data also reported by others deserve to be confirmed in a prospective study. We propose in this project to conduct a prospective open controlled phase II trial in order to assess the efficacy and the safety of intralesional administration of STS for the treatment of calcifications secondary to dermatomyositis or systemic sclerosis and ectopic ossifications secondary to pseudo-hypoparathyroidism 1a type (PHP1A/iPPSD2) (inactivating parathyroid hormone / parathyroid-hormone-related peptid (PTH/PTHrP) signalling disorder).
With limited treatment options available for dermatomyositis, the investigators hypothesize that apremilast, a phosphodiesterase-4 (PDE-4) inhibitor, is a safe and efficacious add-on treatment in patients with refractory cutaneous dermatomyositis. The study will investigate the efficacy, safety and toxicity of apremilast given at 30 mg twice daily to patients with refractory cutaneous dermatomyositis. Clinical response will be assessed at 1 and 3 months. Patients will also be evaluated for durability of their response for up to 6 months. Treatment will be monitored with frequent clinical visits (0, 1, 3 and 6 months) and blood tests (CBC, CMP, creatine kinase, aldolase). Treatment will be discontinued at disease progression or unacceptable adverse events. Disease progression is defined as 4 points increase in the cutaneous dermatomyositis disease area and severity index (CDASI) score, worsening of muscle disease by manual muscle testing (MMT-8) score and 5 points increase in dermatomyositis life quality index (DLQI). 5 mm skin biopsies from lesional skin will be performed before treatment with apremilast and after 3 months of treatment for gene expression profiling and confirmatory immunohistochemical stains.
This is a retrospective descriptive cross-sectional and observational multicenter clinical and progressive study of juvenile dermatomyositis. The aim is to determine the clinical, paraclinical, and evolutive characteristics and therapeutic modalities from a series of juvenile dermatomyositis identified in Alsace between 2000 to 2015.
This is a descriptive, retrospective, multi-center, cross-sectional and observational epidemiological study of incidence and prevalence of juvenile dermatomyositis in Alsace from 2000 to 2015. Alsace is a French region with a low migratory flow
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.
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.
Dermatomyositis (DM) patients experience muscle weakness and low aerobic capacities, which are associated with poor health status and increased mortality. The origin of this muscle impairment remains unknown. The investigators hypothesize that mitochondria functioning is impaired in DM muscle and links with exercise capacities.
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.
