Filter by:1. To determine if BCG immunisation at birth, compared to no BCG immunisation, leads to a reduction in measures of allergy and infection in the first 12 months of life. 2. To evaluate the immunological mechanisms underlying the non-specific effects of BCG by comparing markers of immunity between the BCG and non-BCG groups.
A Phase III, randomised, double-blind, placebo-controlled, multi-centre study to assess the efficacy of olaparib maintenance monotherapy in relapsed high grade serous ovarian cancer (HGSOC) patients (including patients with primary peritoneal and / or fallopian tube cancer) or high grade endometrioid cancer with BRCA mutations (documented mutation in BRCA1 or BRCA2 that is predicted to be deleterious or suspected deleterious (known or predicted to be detrimental/lead to loss of function)) who have responded following platinum based chemotherapy.
Bevacizumab has been found to prolong progression free survival in first line, and more recently, in second line treatment for platinum sensitive ovarian cancer patients who had not received prior treatment with bevacizumab. Recently reported data suggest that patients with colon cancer who receive bevacizumab in more than one line of therapy (beyond progression) have better results. In ovarian cancer, the role of bevacizumab administered in both first and second-line therapies needs to be defined. This study aims to evaluate whether administering bevacizumab in combination with chemotherapy in second-line therapy to patients with recurrent ovarian cancer who have received first-line bevacizumab will be more effective than chemotherapy alone.
The purpose of this study is to determine growth and protein status of infants with cow's milk protein allergy and treated with a newly innovated amino acid formula compared to those with a commercial amino acid formula.
Birch pollen allergy is increasingly common. It causes asthma and early season hay fever. This is because the body recognises birch pollen and reacts to it, leading to symptoms. Many patients with birch allergy get an itchy and/or swollen mouth when they eat fresh fruit (apples, pears, peaches, plums etc). Some fruit proteins have a similar structure to birch pollen; because of this the body recognises these proteins too causing the immune system to respond. This response causes symptoms of itch and swelling inside the mouth and throat. the investigators want to find out whether it is possible to get rid of the fruit-induced symptoms by using a desensitisation procedure that has been developed for treating the kind of hay fever that is caused by birch pollen. Desensitisation involves giving a small injection of pollen just under the skin and gradually increasing the amount each week. This allows the body to build up a "tolerance" to the injected protein. When the pollen is then encountered in real life the immune system reacts less vigorously so symptoms are less severe. This treatment does reduce hay fever symptoms. Our study aims to find out if this tolerance is transferred to the fruit proteins enabling patients to eat apples with minimal symptoms. Patients will be given apple to eat in a hidden form before treatment and their response assessed. They will then receive either active or dummy pollen injections before birch pollen season. A few months after completing these injections they will have another disguised apple test to see whether their symptoms are any better. If symptoms have improved with treatment then this therapy could be offered to patients in the future. This would allow them to eat fresh fruit without worrying about unpleasant symptoms and improve their hay fever symptoms.
Dendritic cells (DC) play a key role in the pathogenesis of allergic diseases. The regulation of blood dendritic cells in patients with hymenoptera venom allergy before and during immune therapy is unknown.
Background: - Urticaria is a common itchy skin disorder that may occur spontaneously or on exposure to a physical trigger (called physical urticaria). - Researchers are studying the genetic basis of a physically induced urticarial syndrome. Once called familial cold urticaria, this condition is now called familial cold autoinflammatory syndrome (FCAS). FCAS is an autoinflammatory disease, a group of inherited disorders characterized by unprovoked episodes of inflammation. Patients with FCAS often have hives, joint pain, and fever following general exposure to cold. - Patients with FCAS have a mutation in a gene that makes a protein called cryopyrin. Cryopyrin seems to be involved with the production of a proinflammatory mediator called interleukin-1 (IL-1). Patients with FCAS and others with autoinflammatory syndromes have benefited from medication that blocks the effects of IL-1. Objectives: - To investigate mechanisms that may cause physical hives or urticaria. - To reproduce urticaria through challenge testing (procedures to test the skin for a reaction to a stimulus), followed by mast cell studies, measurement of IL-1, genetic studies, and other molecular studies to lead to a better understanding of urticaria and to design safe and more effective treatments. Eligibility: - Patients between 6 months and 65 years of age with a documented history of clinically reproducible physical urticaria that triggers hives and that has been evaluated by a physician. Patients should have a letter of referral, including copies of pertinent medical history and laboratory studies, from a referring physician. - Affected and nonaffected family members of such patients. - Exclusion criteria include (1) the presence of conditions that may put the subject at undue risk, such as acute infection, severe thrombocytopenia (a lower than normal number of platelets in the blood), or significant cardiovascular disease; (2) any condition that would make the subject unsuitable for enrollment in this study; and (3) a history of HIV, other known immunodeficiency, or evidence of chronic Hepatitis B and/or C infection. Design: - Researchers will conduct the following tests to verify which triggers cause the hives: - History and physical exam to determine the relationship between the trigger and appearance of the hives. - Blood samples for baseline screening (additional samples may be taken within 8 hours of triggering hives). - Verification of hives using standard challenge testing. - Procedures to trigger urticaria (the challenge testing) include dermatographism (stroking the skin), delayed pressure urticaria (direct pressure), cold-induced urticaria (cold exposure), cholinergic urticaria (exercise, hot water), solar urticaria (sun exposure), localized heat urticaria (direct heat exposure), aquagenic urticaria (room temperature water), and vibratory angioedema (direct vibratory stimulus exposure). - Participants who have a positive history for hives and failed challenge testing (that is, hives resulted from the triggers) will be asked to provide a skin biopsy and additional bloods samples for research purposes. - Participants will be asked to return to the clinic within 1 month if multiple triggers could not be verified during the initial visit, or to return for additional research evaluations, which may include a skin punch biopsy and blood sample collection. Patients may have to stay at the hospital overnight, if required to document the disease. - Nonaffected family members who enroll in this protocol will provide samples for comparison with the family member who has a history of hives. - Participants will receive a small financial compensation for the skin biopsy.
The aim of this study is to prevent asthma and allergies in childhood by supplementation with fish oil (n-3 fatty acids) to the mother during pregnancy. Paticipants are mother and children participating in the ABC-(Asthma Begins in Childhood)cohort. Mothers are recruited during pregnancy and receive supplement with n-3 fatty acids or olive oil (placebo) from week 24 of gestation to 1 week after delivery. The child is followed with acute and planned visit at the research unit and diagnosis of disease is done in the research unit according to predefined algorithms.
The purpose of this study is to determine if small oral and sublingual doses of milk protein are safe and effective in decreasing sensitivity to cow's milk in allergic children.
RATIONALE: Androgens can cause the growth of prostate cancer cells. Androgen ablation therapy may stop the adrenal glands from making androgens. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether androgen-ablation therapy is more effective with or without docetaxel in treating metastatic prostate cancer. PURPOSE: This randomized phase III trial is studying androgen-ablation therapy and chemotherapy to see how well they work compared to androgen-ablation therapy alone in treating patients with metastatic prostate cancer.
