Connective Tissue DiseasesBlood Coagulation Disorders5 moreTo explore the hypothesis that leg ulcers are associated with hypercoagulable states, the CLUE study will evaluate patients with connective tissue disease associated leg ulcers, to identify risk factors (especially hypercoagulability and immunologic characteristics), characterize pathogenesis, predict response to therapy, and assess the impact of lower extremity ulcers on quality of life.
Safety and Efficacy of Anti-Pandemic H1N1 Vaccination in Rheumatic Diseases
Rheumatoid ArthritisSpondyloarthritis10 moreThe 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.
Study of Silicone-Associated Connective Tissue Diseases
Autoimmune DiseasesConnective Tissue Diseases4 moreThis study will examine the possible relationship between silicone implants or injections and the connective tissue diseases scleroderma and myositis. It will explore whether certain factors in the blood or the immune system or other factors are involved in the development of these diseases following silicone implantation or injection. Men and women 18 years of age and older who meet the following criteria may be eligible for this study: Group 1-Patients who have had silicone implants or injections and who later developed scleroderma or myositis Group 2-Patients with scleroderma or myositis who have not had silicone implants or injections Group 3-Healthy volunteers who have had silicone implants or injections and did not develop symptoms or other medical features of connective tissue disorders. Participants will have a thorough history and physical examination, blood and urine tests, chest X-ray and lung function tests. In addition, patients will complete a questionnaire about their procedure (including information such as the types of implanted devices and injections, reason for the procedure, post-operative complications, other illnesses or medical conditions present before and after the procedure, etc.).

The CARRA Registry
Juvenile Idiopathic ArthritisSystemic Lupus Erythematosus11 moreThis CARRA Registry study will create a foundational database for rheumatic diseases of childhood using a novel informatics infrastructure developed as part of the larger clinical project. The creation of a CARRA-wide informatics infrastructure will enable efficient, observational, disease-related data capture across all CARRA sites for pediatric rheumatic diseases. The CARRA Registry study will demonstrate the feasibility of expanding to more data intensive registries for observational studies, comparative effectiveness research, pharmaceutical clinical trials and translational research.

Connective Tissue Diseases and Vitamin D Deficiency
Connective Tissue DiseasesConnective tissue disease (CTD) covers all heterogeneous and broad immunological diseases. These immunological diseases are characterized by inflammation, tissue damage, and abnormal repair. Disorders such as fibrotic tissue or loss of function are seen in the degeneration of the target organ. There is a complex relationship between genetic and environmental factors on the basis of these disorders. Vitamin D deficiency has been frequently observed in autoimmune diseases such as systemic lupus erythematosus, diabetes mellitus, and rheumatoid arthritis. Vitamin D deficiency is primarily seen with musculoskeletal complaints and is an early warning of osteomalacia. Muscle weakness is most common in the trunk, shoulders and hips. It is characterized by difficulty in climbing stairs, getting up from sitting or lying position, feeling of heaviness in the legs, duck-like gait, difficulty getting up from a chair, fatigue easily, inability to lift objects with arms and hands. Patients experience decreased exercise capacity as a result of pain and muscle weakness. In addition, vitamin D deficiency causes smooth muscle contraction and an increase in airway inflammation. As a result, it was observed that the disease course and symptoms were more severe in CVD patients with vitamin D deficiency. In a study conducted with rheumatoid arthritis patients, the quality of life, physical activity and depression levels of patients with vitamin D deficiency were compared with the control group. The evaluation parameters of rheumatoid arthritis patients were worse than the control group. Vitamin D levels were compared with sleep, anxiety and depression levels in patients with systemic lupus erythematosus. A positive relationship was found between vitamin D deficiency and sleep disturbance level. It has been observed that the life expectancy of patients with connective tissue disease is significantly reduced compared to healthy ones. Exercise capacity and oxygen consumption decreased in these patients.
Early Detection of Cardiac Impairment and Prediction of RV Hypertrophy in Patients With CTD
Connective Tissue DiseasesRight Ventricular HypertrophyThere have been reports suggesting that progressive RV failure and death in connective tissue disease (CTD) are related to right ventricular hypertrophy (RVH) and dilation, irrespective of pulmonary arterial hypertension (PAH). The investigators aim to identify cardiac markers that occur before RVH and to investigate predictors of RVH.
Exploring the Comorbidity Between Mental Disorders and General Medical Conditions
OrganicIncluding Symptomatic42 moreMental disorders have been shown to be associated with a number of general medical conditions (also referred to as somatic or physical conditions). The investigators aim to undertake a comprehensive study of comorbidity among those with treated mental disorders, by using high-quality Danish registers to provide age- and sex-specific pairwise estimates between the ten groups of mental disorders and nine groups of general medical conditions. The investigators will examine the association between all 90 possible pairs of prior mental disorders and later GMC categories using the Danish national registers. Depending on whether individuals are diagnosed with a specific mental disorder, the investigators will estimate the risk of receiving a later diagnosis within a specific GMC category, between the start of follow-up (January 1, 2000) or at the earliest age at which a person might develop the mental disorder, whichever comes later. Follow-up will be terminated at onset of the GMC, death, emigration from Denmark, or December 31, 2016, whichever came first. Additionally for dyslipidemia, follow-up will be ended if a diagnosis of ischemic heart disease was received. A "wash-out" period will be employed in the five years before follow-up started (1995-1999), to identify and exclude prevalent cases from the analysis. Individuals with the GMC of interest before the observation period will be considered prevalent cases and excluded from the analyses (i.e. prevalent cases were "washed-out"). When estimating the risk of a specific GMC, the investigators will consider all individuals to be exposed or unexposed to the each mental disorder depending on whether a diagnosis is received before the end of follow-up. Persons will be considered unexposed to a mental disorder until the date of the first diagnosis, and exposed thereafter.
