Safety and Efficacy of Anti-Pandemic H1N1 Vaccination in Rheumatic Diseases

Rheumatoid ArthritisSpondyloarthritis10 more

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.

Outcome in Patients With Recent Onset Polymyositis and Dermatomyositis

PolymyositisDermatomyositis

Most patients respond to medical treatment with corticosteroids and immunosuppressive treatment, but a majority of patients develop sustained muscle impairment. The aim of this study was to evaluate the outcome of muscle endurance assessed with the Functional Index-2 (FI-2), muscle strength assessed by the MMT-8 and disease activity assessed by the six item core set at 6 and 12 months following diagnosis in patients with polymyositis (PM) and dermatomyositis (DM). 72 patients diagnosed with probable or definite PM or DM 2003-2010 who performed the FI-2 and the MMT at the time of diagnosis were included in this Swedish Myositis Register study. All patients had performed both the Functional Index-2 assessing muscle endurance and the Manual Muscle test (MMT) assessing isometric muscle strength. Physician Global assessment based on the evaluation of the consensus recommended six item core set for disease activity assessment was also included. Data were analysed on group levels as well as with criteria for individual responder criteria. A responder was identified as improving at least 20 % compared to baseline.

Study of the Prevalence of Polymyositis and Dermatomyositis in Normandy

PolymyositisDermatomyositis

Polymyositis and dermatomyositis are characterized by the association to a myopathic syndrome, inflammatory infiltrates in the skeletal muscle. They remain, even today, an important factor of morbidity and mortality in these patients. At present, studies that evaluated the prevalence of polymyositis / dermatomyositis are very few; they were mainly recorded in the United States and Japan, the prevalence of polymyositis / dermatomyositis has been estimated between 3.5 and 21.5 cases / 100 000 (according to the old diagnostic criteria of Bohan and Peter). However, previous works are old and retrospective; above all, they have almost always been performed (90% of cases) from cases reported to the hospital, leading to selection bias and an underestimate of the true prevalence of polymyositis / dermatomyositis in the general population. Thus, these data lead to achieve this epidemiological study, descriptive, multicenter, based on the population of Normandy.

Hand Function in Patients With Poly- or Dermatomyositis

PolymyositisDermatomyositis

The aim of this study is to investigate the hand function in patients with poly-and dermatomyositis and compare this to healthy individuals and norm values and secondly if hand function correlates to activity performance and health related quality of life. The study is a cross-sectional study. To assess hand function the investigators will measure grip force with Grippit and arm/hand mobility using EPM-ROM scale. The activity performance will be measured with Myositis Activities Profile and health related quality of life will be assessed with SF-36. The investigators' hypothesis is that hand function is reduced in comparison to the healthy population and that hand function affects both activity performance and health related quality of life.

Studies of the Natural History and Pathogenesis of Autoimmune/Connective Tissue Diseases

Autoimmune/Connective Tissue DiseasesIdiopathic Inflammatory Myopathies2 more

This study will define the major genetic risk and protective factors for idiopathic inflammatory myopathies (IIM), a group of immune disorders affecting connective tissues such as muscles. It will also identify new environmental risk factors for IIM and identify immune responses in myositis and related diseases. There are many forms of IIMs, and the causes of these diseases are unknown. However, scientists suspect that they result when people with some genetic factors that predispose them-that is, put them at greater risk-are exposed to certain environmental triggers. Some of those triggers include food, drugs, biologics (such as a vaccine to prevent disease), medical devices and occupational exposures. Patients, including children under 18, who had a diagnosis of myositis, a related autoimmune disease, or a rheumatic disease, as well as their blood relatives, and control subjects who were in good health have already been recruited for this study. The evaluation consisted of one outpatient visit to the patient's doctor, who will obtain a medical history and conduct a physician examination. Patients spent 20 to 30 minutes to answer written questions. There was a blood collection of about 6 tablespoons. If there was a major change in patients' medical conditions, they were asked to return for a second outpatient evaluation to determine whether any of the blood tests or antibodies, which show an immune response, had changed. Blood samples collected will be used only for laboratory research studies. The samples have been identified by a code, and all other identifying information have been removed. During the study, researchers will explore possible environmental risk factors, including studies of infectious and non-infectious agents. They will analyze the blood for genetic markers and test for certain antibodies. Laboratory results will be evaluated as they relate to the signs, symptoms, and severity of patients' illnesses. That would help researchers to better understand patterns of the diseases and the outcomes for patients. This study will not have a direct benefit for patients. However, results from the study can be made available to patients' doctors for use in appropriate care. Also, it is hoped that information gained can help other people in the future. ...

Genetic and Family Studies of Inherited Muscle Diseases

DermatomyositisGlycogen Storage Disease Type II3 more

The purposes of this study are to identify gene mutations in patients with the muscle diseases phosphofructokinase (PFK) deficiency, acid maltase deficiency (GAA deficiency) and to learn more about how these diseases develop. PFK deficiency is a mild, exercise-related illness. The childhood form of GAA deficiency (Pompe disease) affects the heart and liver and is rapidly fatal. The adult form begins in midlife and involves degeneration of skeletal muscles, leading to weakness and muscle wasting. The following groups of individuals may be eligible for this study: Group A: Patients with PFK deficiency, acid maltase deficiency, and relatives who also are affected. Participants in this group will undergo a brief medical and family history, blood sample collection, and possibly a physical examination, review of medical records, and interview with the patient's physician. Group B: Unaffected family members of patients in group A, including both blood relatives and spouses. People in this group may be asked to provide a history and genetic information. A review of medical records, interview with the individual's physician, and blood sample may also be requested. Group C: Control subjects. This group will provide a small blood sample or buccal mucosal sample (tissue sample collected by brushing the inside of the cheek). The samples will be coded and the investigators will not know the participants' identities. DNA from these samples will be analyzed for frequency of gene mutations. Genetic counseling will be arranged for patients, as appropriate.
