MyositisThe purpose of the study is to understand how the study medicine PF-06823859 works in people with idiopathic inflammatory myopathies (DM and PM). These disorders cause inflammation that weakens the muscles that are important for movement and may also cause skin rash in people with DM. This study is seeking participants who: Are 18 years of age or older. Have active DM or active PM. Are receiving a stable dose of 1 corticosteroid taken by mouth and/or 1 traditional immunosuppressant. Note: Corticosteroids and immunosuppressants are medicines that help reduce inflammation and may signal to the immune system not to attack the body. Dermatomyositis (DM) is a rare disease that causes muscle inflammation that results in muscle weakness and low muscle stamina. Patients with DM have a characteristic skin rash. Polymyositis (PM) is a rare disease that involves mainly muscle inflammation resulting in muscle weakness, that can sometimes be painful. Patients with DM and PM may have trouble going up the steps, walking or getting to a standing position. Some of the participants will receive the study medicine (PF-06823859) and some will receive placebo (which is similar to study medicine but contains no medicine in it). The study medicine or placebo will be given as an intravenous (IV) infusion (directly into the veins), which takes about1 hour; every 4 weeks from Day 1 to Week 48 of the study. Both PF-06823859 and placebo and will be given at the study site. The study will compare the experiences of people receiving study medication to those of the people who do not. This will help to see if PF-06823859 is safe and effective. Participants will take part in this study for about 13 months. During this time, participants will have 16 study visits. These visits will be performed at the study site, but some study visits may be available at home or via mobile clinic if the study location participates in this option.
Add-on Intravenous Immunoglobulins in Early Myositis
Inflammatory MyopathyIdiopathic5 moreIn patients with myositis early immunomodulation by intensive treatment ("hit-early/hit-hard" principle) may induce faster reduction of disease activity and prevent chronic disability. Intravenous immunoglobulin (IVIg) in addition to standard treatment with glucocorticoids may be beneficial for this purpose: add-on IVIg improved symptoms in steroid-resistant myositis, and first-line monotherapy IVIg led to a fast and clinically relevant response in a pilot study in nearly 50% of patients with myositis.

High-intensity Strength Training in Myositis

Adult and Juvenile Myositis
DermatomyositisPolymyositis1 moreThis study will evaluate subjects with adult- and childhood-onset myositis to learn more about their cause and the immune system changes and medical problems associated with them. Myositis is an inflammatory muscle disease that can damage muscles and other organs, resulting in significant disability. Children or adults with polymyositis or dermatomyositis or a related condition may be evaluated under this study. Healthy children or adults will also be enrolled as "controls," for comparison of test results. All patients will undergo a complete history (including completing some questionnaires) and physical examination, review of medical records, and blood and urine tests. Patients may then choose to participate in an additional 1- to 5-day evaluation, which will include some or all of the following diagnostic, treatment or research procedures: Standardized muscle strength testing, range of motion of joints and walking (gait) analysis by a physiotherapist; completion of a questionnaire regarding ability to perform daily tasks Skin assessment, possibly including photographs of lesions and a skin biopsy (removal of a small skin sample under local anesthetic) Magnetic resonance imaging (scans that use magnetic fields to visualize tissues) of leg muscles Swallowing studies, including a physical examination and questionnaire on swallowing ability, studies of tongue strength, and ultrasound imaging during swallowing, and possibly, a modified barium swallow Voice and speech assessment, possibly including computerized voice analysis and laryngoscopy-analysis of the larynx (voice box) using a small rigid scope with a camera placed in the mouth to view and record vocal cord function Pulmonary function tests (measurement of air moved into and out of the lungs, using a breathing machine) to evaluate lung function and, possibly, chest X-ray Electrocardiogram (measurement of the electrical activity of the heart) and, possibly, echocardiogram (ultrasound imaging of the heart) Endocrine evaluation Eye examination, in patients with vision loss or other eye symptoms Nutrition assessment to evaluate muscle mass and muscle wasting, including tape measurements or bioelectric impedance testing, a painless procedure in which wires are attached to the extremities with a sticky paste. Muscle ultrasound. Electromyography (record of the electrical activity of muscles) Muscle or skin biopsy (removal of a small piece of muscle tissue for microscopic examination) All patients may have only a one-time evaluation or may return for one follow-up evaluations (either the 1-day or 3- to 5-day evaluation) over a 1-year period. Healthy children will undergo a medical history and brief physical examination; blood and urine tests; speech and swallowing studies including questionnaires and physical examination, tongue strength, and ultrasound study; and bioelectric impedance testing. Children 8 to 18 years old may also have exercise testing.
Environmental Risk Factors for the Anti-synthetase Syndrome
MyositisDermatomyositis3 moreBackground: Like other complex diseases, autoimmune diseases are the result of numerous causes, including genetic and environmental factors. Some researchers believe that people who are susceptible to autoimmune disorders develop them when the body reacts to environmental or other factors by creating white blood cells that attack the body s own tissues, which then progresses to autoimmune diseases. These immune-triggered disorders can overlap with one another to some extent, but most autoimmune diseases have certain distinct triggers. The autoimmune disorder myositis weakens the muscles and may cause other health problems. Environmental exposures associated with myositis include ultraviolet radiation, stressful life events and muscle overexertion, collagen implants, infections such as retroviruses and streptococci bacteria, and certain drugs and chemicals. Some individuals with myositis also produce proteins in the blood called autoantibodies that react with certain parts of the person s own cells, called synthetases, which are involved in making new proteins. A syndrome called the anti-synthetase syndrome, which includes myositis and lung disease, is associated with having the anti-synthetase autoantibodies. Researchers are interested in studying differences in environmental exposures in individuals with myositis. This study is being conducted to determine if persons with the anti-synthetase syndrome have had different environmental exposures before disease onset compared with other patients with myositis who do not have this syndrome and also compared with healthy volunteers. Objectives: - To determine whether selected infectious and noninfectious environmental exposures are more common in individuals who have myositis with the anti-synthetase syndrome, compared with healthy volunteers. Eligibility: - Individuals who have been diagnosed with myositis (with or without anti-synthetase autoantibodies), and healthy volunteers without autoimmune disorders. Design: Participants will be screened with a full medical history and physical examination, and will provide blood, urine and house dust samples. Participants will complete questionnaires about their medical history and the types of exposures they have had at work, at home, and elsewhere. Participants who have myositis will also be asked about certain infections, heavy exercise or physical exertion, sun exposure, tobacco and alcohol use, and stressful events prior to being diagnosed with the disease. Healthy volunteers will be asked about the same exposures before the date of diagnosis of disease of the myositis subject to which they have been matched. Participants will receive a kit that contains instructions and a filter to be put onto their vacuum cleaner to collect house dust in the bedroom. This dust will be kept for possible future analyses of infectious or toxic agents based on the other results from the study. Individuals with myositis will have other tests as clinically indicated, including lung function tests and imaging studies....
