Active clinical trials for "Immune System Diseases"

This is a pilot study (a small scale study testing procedures so that the investigators can apply this to a larger scale study). This study will test the accuracy of a new brain scan (Magnetic Resonance Imaging) technique in predicting the diagnosis of multiple sclerosis (MS) in patients where there is uncertainty about the diagnosis. For patients where there is a suspicion (but not definite) diagnosis of MS, an additional MRI brain scan will be offered. There will be no other research tests and the patient is followed up to see what the eventual diagnosis is. The investigators will then review the original brain scan to see if this predicted the diagnosis of MS or not.

The study will examine the prevalence of venous thromboembolism in children with acute lymphoblastic leukaemia treated in accordance with NOPHO ALL-2008. The investigators will prospectively study clinical symptomatic thromboses, asymptomatic central line-associated thromboses, and infections.

The purpose of this study is to determine the ability of STRATUS OCT and high resolution OCT to detect and to quantify the neural loss in multiple sclerosis and neuromyelitis optica and its subtypes.

Rheumatoid arthritis (RA) is an autoimmune disease of unknown etiology characterized by peripheral polyarthritis, symmetric, which leads to joint destruction and deformity. It is estimated that the RA reaches about 0.5% of the population. According to data from DATASUS, was responsible for 26,671 hospitalizations, 229 deaths and cost exceeding R$ 20 million in 2005-2007. The main bodily changes are related to joint problems, however, systemic manifestations are also found in organs such as lung and heart. Although cardiovascular diseases are the most responsible of the deaths AR, pulmonary complications are common and account for 10% to 15% of all mortality. Anaya and colleagues point out that the pulmonary involvement contributes significant morbidity and mortality in these patients. Although pulmonary involvement is a frequent manifestation in RA, the prevalence and nature of rheumatoid lung disease has not yet been precisely established. Several lung disorders such as interstitial pulmonary fibrosis, pulmonary nodules and bronchiolitis may ocorrer1. Laitinen et al point out that studies of lung function appear to be a valuable helper for radiography in the evaluation of pulmonary involvement in connective tissue diseases. Previous studies indicate that patients with RA have an increased incidence of abnormal lung function, according to assessments including spirometry, lung volume tests and diffusion capacity of carbon monoxide. Thus, the main objective of this study is to analyze the respiratory mechanics of patients with RA. Specific objectives were to seek to understand whether a relationship exists between duration of rheumatoid disease and lung function in these patients. For this, the investigators used 18 subjects in the control group, free of pulmonary disease and / or heart, all nonsmokers. In the RA group, a total of 72 patients divided into 4 groups of 18 volunteers each, classified according to disease duration (0-5 years, 6-10 years, 11-15 years and> or = 16 years). It is noteworthy that all patients in the RA group will also be non-smokers, since it is already known in the literature that smoking impairs lung function. All individuals will perform the function test with a trained technician and qualified to function. The examinations will be conducted: Forced oscillation technique and spirometry, in that order.

This study is a cross sectional study of patients diagnosed with clinically isolated syndrome (CIS) and RRMS, who will undergo a series of tests to assess cognitive impairment, fatigue severity and depressive symptoms. Cognitive impairment will be assessed with Multiple Sclerosis Inventory Cognition (MUSIC) and symbol digit modalities test (SDMT), fatigue severity will be measured with the Fatigue Scale for Motor and Cognitive Functions (FSMC) and depressive symptoms with the Beck Depression Inventory (BDI). All tests mentioned above are validated for MS patients. In the second step we will use our large longitudinal database of serial MRI examinations from which a linear measurement of CCI will be retrospectively calculated.

The purpose of this study is to determine whether the orthostatic hypotension reported among subjects during bortezomib-containing regimen is caused by a dysfunction of the autonomic nervous system (ANS).

The purpose of this study is to evaluate the improvement in severity of Atopic Dermatitis and quality of life after 4 weeks of treatment in the Dead Sea.

To assess specificity and overall accuracy of interim dual-point acquisition PET in predicting treatment outcome. The study is aimed at assessing the specificity of interim dual-point PET performed after 2 ABVD cycles to predict treatment outcome in early-stage Hodgkin's Lymphoma patients presenting bulky lesions at baseline.

The purpose of this study is to assess the glycemic response to cycling road races (using continuous glucose monitoring ) in elite athletes with type 1 diabetes and non-diabetic controls. The investigators will also assess the relationship between power/work during cycling (using a power meter) and the subject's glucose profile.

Individuals with a past diagnosis of severe combined immune deficiency (including many cases of "leaky SCID", Omenn syndrome, and reticular dysgenesis) who have undergone blood and marrow transplant, gene therapy, or enzyme replacement in the past may be eligible for this study. The purpose of study is to look backwards at what has already been done in the. Over 800 patients with SCID are expected to be enrolled, making this one of the largest studies ever to describe outcomes for patients with SCID treated at many different hospitals around North America.
