Filter by:Ayurvedic medicine has been practiced in for more than 2,500 years. Ashwagandha is one of the most widely utilized herbs in the system. It is thought to affect the endocrine, immune, nervous, and cardiopulmonary systems. This study is designed as a preliminary investigation of the effects of Ashwagandha on stress, inflammation, and immune modulation. Participants will take the liquid extract in cow's milk twice a day for five days. The results of initial, one-day, and final blood draws will be compared to determine participant's beginning and ending levels of cortisol, inflammatory cytokines, and immune-cell activation (CD4 T-cells, CD8 T-cells, B cells and natural killer cells). Measurements will be completed using flow cytometry and ELISA assay. The purpose of this study is to determine which effects of Ashwagandha are most suitable for further investigation.
In the Netherlands, the human Papillomavirus (HPV) vaccination will be added to the National Vaccination Program for girls to protect against the development of cervical cancer. The vaccine protects against HPV type 16 & 18, which cause about 75% of cervical cancer. Studies have shown that the vaccine is effective in healthy subjects in preventing infection by HPV 16 & 18. However, no evidence exists on the immunogenicity and safety of HPV vaccination in patients with an immune system disorder, such as primary humoral immunodeficiency (i.e. hypogammaglobulinemia) or autoimmune diseases. Concerns exist that vaccination may cause an aggravation of the underlying disease. In addition, the immune response to vaccination may be diminished due to immunosuppressive therapy or the underlying disease. Objective: The primary goal of the current study is to study the immunogenicity of HPV vaccination in patients with an autoimmune disease and a primary humoral immunodeficiency. Based on retrospective analysis with other vaccines we hypothesize that patients with autoimmune diseases who are under immunosuppressive medication and patients with a immune system disorder have a decreased serological response to HPV vaccination, and that the produced HPV antibodies titers decrease more rapidly than in healthy individuals. The secondary objective is to explore safety of HPV vaccination and immune regulatory mechanisms induced by vaccination in a subset of patients. The investigators hypothesize that HPV vaccination is safe and that HPV-induced regulatory T cells are able to prevent an increase in the activity of an autoimmune disease.
Increase prevalence of thyroid autoimmunity is found in patients with chronic urticaria. About 5-34% of chronic urticaria patients is associated with the presence of thyroid autoimmunity who are euthyroid status whereas 5-10% of them with either hyperthyroidism or hypothyroidism.
This study, done in collaboration with Cornell University in New York, will explore the potential role of the body s immune response to gluten in ataxia. Celiac disease is an autoimmune disorder that is triggered by the ingestion of wheat gluten and related proteins in genetically susceptible individuals. Some people with celiac disease also develop ataxia, which is a loss of muscle coordination, leading to imbalance. The cause of the associated ataxia is not well understood, but it is suspected to be related to the immune response towards gluten in these patients. Preliminary results indicate that antibodies in people with celiac disease can react with brain proteins, which might have a role in the associated neurologic deficits. The aim of this study is to characterize the immune response in the ataxia that is associated with celiac disease. People 18 years of age and older with 1) ataxia and no celiac disease, 2) ataxia plus celiac disease and 3) matched healthy control subjects will be enrolled at the NIH. People with celiac disease only will be enrolled at Cornell University. All participants have a blood sample drawn for various tests of immune function as well as genetic tests. Healthy volunteers also have a history and physical examination if they have not had one done at NIH in the past year. Some patients may require additional clinical evaluations for clinical or diagnostic reasons.
This is an observational study designed to help researchers understand the genetics and pathogenesis of type 1 diabetes, and to identify biomarkers for disease and disease complication prediction.
The objective of the proposed study is to assess the role of smoking and complex gene-smoking interactions in two understudied Rheumatoid Arthritis (RA)groups.
It is difficult to predict how a women with an autoimmune disease will do during pregnancy. Some women will improve, others will worsen. Some pregnancies progress normally and others become very complicated. The Duke Autoimmunity in Pregnancy (DAP) Registry will enroll women with autoimmune diseases, such as lupus, rheumatoid arthritis, scleroderma, and Sjogren's syndrome who wish to become, or already are, pregnant. We will follow these women throughout pregnancy to better understand how their autoimmune disease affects their pregnancy, and vice versa.
This study was designed to evaluate the incidence of both, inherited and adquired thrombophilia, and thyroid autoinmunity in unknown infertility (UI), implantation failure (IF) and recurrent miscarriage (RM). To focus on these particular disorders and to rule out another potential confounding variables, 4 particular groups of women were created. Only young women (< 38 years old), patients whose previous preimplantation genetic screening (PGS) cycles displayed an acceptable rate of aneploidies, and women without organic uterine abnormality, autoimmune disease or endocrine disorder were included in the study.
The purpose of this research study is to test the safety, tolerability, and effectiveness of Topical AmphiMatrix with Nitroglycerin (MQX-503) to relieve Raynaud's symptoms and increase blood flow to the fingers.
The Purpose of this study is to determine the response to two different strengths of a topical gel containing nitroglycerin in patients with Raynaud's disease.
