The primary objective of this study is to assess the efficacy of IgPro20 subcutaneous (SC) doses in comparison to placebo in adult subjects with DM, as measured by responder status based on Total Improvement Score (TIS) assessments.
Background: - Myositis is a rare disease in which the body s immune cells attack the muscle tissue. It can cause muscle weakness, swelling, and pain. It can develop in people with no history of muscle problems. Environmental exposures may determine who develops myositis. Genes may also affect development of the disease. - Some people who serve in the military develop myositis. However, other military personnel do not. Researchers want to compare military personnel with and without myositis. They will look for common factors that might have led to the disease. Objectives: - To study environmental risk factors for myositis in military personnel. Eligibility: - Military personnel who developed myositis during their period of service. - Healthy military personnel who do not have myositis or another autoimmune disease. Design: - Participants will have a physical exam and medical history. - Participants will fill out forms about environmental exposures, particularly while in the military. The questions will ask about past infections, vaccines and medications, and personal habits. They will also ask about participants occupations during military service and their deployments. - Participants will also provide blood samples for study. - No treatment will be provided as part of this study.
Polymyositis (PM), dermatomyositis (DM) and inclusion body myositis (IBM)belong to a group of inflammatory muscle disorders, of unknown cause, that are characterised by skeletal muscle inflammation and progressive muscular weakness, which can be debilitating and chronic in nature (occasionally fatal). The current treatment options for these conditions are steroids and various other immunosuppressive drugs. However, these are usually only partially effective at reducing symptoms, and their toxic side effects also limit their usefulness. In order to develop more specific treatments for myositis in the future (and therefore more effective), it is important to understand the exact mechanisms that cause the disease in the first instance. In other similar inflammatory diseases such as rheumatoid arthritis (RA) and systemic lupus (SLE), it is known that changes to the Human Leukocyte Antigen(HLA), as well as certain inflammatory cytokines, are involved in both the development and expression of the disease. As many of the inflammatory mechanisms that cause damage in PM, DM and IBM are similar to those in RA and SLE, it seems likely that similar genetic factors will also be involved in the development and expression of PM, DM and IBM. In order to understand the genetic aspects / causes of myositis, and ultimately develop more effective treatment therapies in the future, patients with PM, DM or IBM, will be asked to give 20 mls of blood. These blood samples, along with the patient's clinical details, will then be sent to the Centre for Integrated Genomic Medical Research (CIGMR), at The University of Manchester, where all of the genetic analyses will take place. By understanding the genetic cause of the disease, it should be possible to design specific drugs for treating the condition in the future.
The prognosis of rheumatic diseases has improved considerably with development of therapy. However, infections are considered the most important cause of morbidity and mortality in this group of patients. One of the ways to prevent such complications is vaccination. In 2009, a new pandemic strain of influenza virus (A/H1N1/2009) has emerged raising major concerns for public health. Patients under immunosuppressive therapy have indication for immunization against influenza virus H1N1. There are, however, concerns about possibility of reactivation of autoimmune diseases, determine adverse events and insufficient immunogenicity in these patients. The lack of studies evaluating the efficacy and safety of the vaccine against influenza A(H1N1)/2009 in these rheumatic patients led to the development of this research. The objectives of this study are to evaluate the humoral response and safety of the vaccine virus A(H1N1)/2009 in immunosuppressed patients with rheumatic diseases compared to healthy controls. We have recruited 400 patients with rheumatoid arthritis, 350 with spondyloarthritis, 1000 with systemic lupus erythematosus (SLE), 150 with dermatomyositis (DM), 100 with mixed connective tissue disease, 150 with systemic vasculitis, 250 with systemic sclerosis (SSc) , 100 with Sjögren's syndrome, 100 with antiphospholipid syndrome, 100 patients with juvenile idiopathic arthritis, 80 with juvenile SLE, and 80 with juvenile DM, followed at our Rheumatology Outpatient Division and Unit Pediatric Rheumatology Children's Institute, HC-FMUSP. The control group was recruited were 200 healthy employees of ICHC-FMUSP. Informed consent was obtained from all participants and the study was approved by the Local Ethical Committee. All subjects were vaccinated against influenza virus A/(H1N1)/2009 (vaccine approved and supplied by Instituto Butantan-São Paulo). Blood samples was collected to measure levels of antibodies inhibiting hemagglutination by influenza virus A (H1N1)/2009 immediately prior to vaccination and 21 to 28 days after vaccination., Participants fulfilled a questionnaire on the immediate side effects of the vaccine. All patients with rheumatoid arthritis, spondyloarthritis, SLE, DM, systemic vasculitis, juvenile idiopathic arthritis, juvenile SLE, and DM were assessed before and 21 days after vaccination for clinical, laboratory parameters of disease activity as well as treatment. Continuous variables will be compared by t-test to evaluate differences between patients with rheumatic diseases versus healthy controls. Differences between categorical variables will be evaluated using the chi-square or Fisher exact test. Statistical significance was set at p<0.05.
Therapeutical trial in patients with idiopathic polymyositis and dermatomyositis is proposed. The study will investigate the safety and efficacy of combined methotrexate + glucocorticoids treatment compared with glucocorticoids alone. This will be a randomised, open-label, assessor-blind, international multicenter trial, performed in several European centres interested in research on inflammatory myopathies. A total number of 50 patients with polymyositis/dermatomyositis will be randomised into two groups (1: Methotrexate + glucocorticoids and 2: Glucocorticoids only). Patients will be equally distributed between the two groups providing 25 patients per treatment arm. The randomisation will be based on random numbers generated by a computer program. After being enrolled in the study, the patients will receive 12 months of therapy followed by a 12-month follow-up period. The primary endpoint is the total dose of glucocorticoids (calculated in mg/kg weight), which will be administered for 12 months between baseline and the end of treatment. There are several of secondary objectives, which will be pursued during and after the trial. Disease activity and damage will be prospectively assessed by the newly developed tools for myositis disease activity (MYOACT and MITAX) and for myositis damage (MYODAM and MDI. Other secondary objectives comprise: global assessment of activity and damage by patients and by physician, muscle endurance, muscle strength by manual muscle testing, enzyme levels, glucocorticoid related side effects, functional ability measured by HAQ, quality of life by SF-36, and number of patients with treatment failures. The other aims will also include (i) search for reliable prognostic parameters in the further prognosis of patients with inflammatory myopathies and (ii) studies on the pathogenic aspects of inflammatory myopathies. The investigations of serum, lymphocytes, muscle tissue and MRI will be organized. DNA and RNA will be stored for future genetic studies. Patients with definite or probable polymyositis or dermatomyositis diagnosed according to diagnostic criteria will be enrolled. They will have disease activity that according to physician's own judgement requires high dose immunosuppressive treatment (based on clinical assessment of weakness, elevation of muscle enzymes and, if available, on magnetic resonance imaging findings). Patients should be previously untreated with the exception of glucocorticoid treatment up to 8 weeks. Patients with other than primary idiopathic polymyositis or dermatomyositis, such as drug-induced myositis, myositis in association with other connective tissue disease, inclusion body myositis, malignancy related myositis, and juvenile dermatomyositis will be excluded. All patients will start with prednisone 1 mg/kg/day and the dose will be tapered if patients meet definition of improvement, which has been proposed by IMACS group. Methotrexate will be administered orally, once weekly, with a starting dose 10 mg. This will be increased gradually to 25 mg/week if tolerated by week 5. Patients will be first assessed after 2 weeks and than monthly for a period of 48 weeks. There will be a follow-up after a further 1 year in order to find out the impact of the early treatment on the long-term disease outcome. All efficacy analyses will be performed using intention-to-treat population (ITT). In addition, the primary and secondary variables will be analysed using the per-protocol population, which will contain all patients in the ITT population, who also reached Week 48 of treatment without any major protocol violations. The safety population, which will contain any patient who received at least one dose of study drug, will be used for all safety analyses.
