Filter by:Metabolic syndrome (MetS) is a group of important cardiovascular risk factors: abdominal obesity, dyslipidemia, hyperglycemia, and high blood pressure. Treatment requires lifestyle changes and pharmacological therapy with different medications for each component. Ellagic acid (EA) is a polyphenol that has shown health benefits in multiple experimental studies. Patients consume EA without prescription; considering there aren't studies that demonstrate its effectiveness on MetS, it is important to evaluate the possible effects of AE on this pathology. METHODOLOGY: Current study is a double-blind, placebo-controlled clinical trial. The aim of this study is to evaluate the effect of AE on the components of metabolic syndrome, insulin sensitivity, and insulin secretion.
Peanut allergy is the most common cause of severe allergic reactions to food. Onset is common in childhood, but in contrast to other food allergies such as cow's milk and egg, peanut allergy tends to persist into adulthood. It is associated with a significant impact on quality of life, both for the affected individual and their family. There is no current cure for peanut allergy. Oral peanut immunotherapy (OIT) using defatted, roasted peanut flour has been demonstrated to offer potential in this regard, but is associated with significant and frequent reactions and can cause life-threatening allergic symptoms. The investigators have previously demonstrated that the processing of peanuts through boiling results in a relatively hypoallergenic product due to the loss of key allergenic components from peanut into the water. This has been tested in a recently-completed Phase 2b/3 trial (The BOPI Study, Clinicaltrials.gov NCT02149719; HRA reference 15/LO/0287): 47 children/ young people with peanut allergy confirmed at double-blind, placebo-controlled food challenge (DBPCFC) were randomised (2:1) to receive either oral immunotherapy (updosing using boiled peanut for ~6 months, followed by maintenance with roasted peanut) or standard treatment (allergen avoidance). Participants underwent repeat DBPCFC at 12 months to assess response, following which peanut OIT was stopped and sustained unresponsiveness assessed after 4 weeks (4SU). 24/32 participants (100% per protocol) achieved the primary outcome of desensitisation to >1.44g peanut protein (approximately 6-8 peanuts, p<0.0001)Íž of those 14 tolerated >4.4g peanut protein. 13/24 participants achieved 4SU. There was no significant change in threshold in the control group (p>0.05). Boiled peanut OIT had a favourable safety profile, with under 2% of doses associated with gastrointestinal symptoms. The BOPI-2 study is a non-inferiority study to demonstrate that boiled peanut is at least as effective as peanut flour in treating children with peanut allergy. The study will compare the rate of adverse events and other safety outcomes between these two interventions, and assess the immunological mechanisms involved, a secondary aim being to develop clinically-useful predictors for identifying individuals likely to undergo successful desensitisation.
This study is a multi-center, randomized, double-blind, placebo-controlled study in participants 1 to less than 56 years of age who are allergic to peanut and at least two other foods (including milk, egg, wheat, cashew, hazelnut, or walnut). While each participant may be allergic to more than two other foods, the primary endpoint/outcome in this study will only be assessed in peanut and two other foods for each participant. The primary objective of the study is to compare the ability to consume foods without dose-limiting symptoms during a double-blind placebo-controlled food challenge (DBPCFC), after treatment with either omalizumab or placebo for omalizumab.
Metastatic prostate cancer is an incurable disease that typically spreads beyond the prostate. The standard of care is to systemically treat the disease with androgen deprivation therapy (ADT). However, the disease progresses in virtually all patients to the state of castration resistant prostate cancer (CRPC), with a median time to progression of 24 months. Patients with high volume disease (with either visceral metastasis and/or bone metastasis) exhibit a worse prognosis, with a median clinical progression of 14 months. Recently, the CHAARTED and STAMPEDE studies demonstrated that the combination of Docetaxel (chemotherapy) and ADT delayed the clinical progression and improved the survival a median of 14 months (17 for high volume patients). Nevertheless, the prognosis of patients with high volume metastatic disease continues to be poor. Meanwhile the immunotherapy, the use of antibodies that recognize tumoral cells and promote the immune system activity against the cancer, has emerged as a very useful option in many cancers. Among others, the antibodies Nivolumab and Ipilimumab have been approved for the treatment of multiple types of cancer. In this context, SOGUG (Spanish Oncology Genitourinary Group) has designed this new study "PROSTRATEGY" with the objective of evaluating whether the addition of immunotherapy to chemotherapy and ADT improves the prognosis and survival of patients with high volume metastatic hormone-sensitive prostate cancer.
This is a single-blind randomized controlled trial, aiming to evaluate the effects of vaginal seeding on body mass index as well as allergy risk for cesarean-delivered infants. It will be conducted in Liuyang city of China, and the targeted sample size is 106. All the eligible pregnant women will be randomly assigned to either the intervention or control group, and their babies of the participants will be followed up to 24 months of age.
Oral immunotherapy (OIT) is a food allergy treatment where small amounts of the food a child is allergic to is eaten and gradually increased over time with the aim to be able to eat a certain amount of the allergen without experiencing an allergic reaction. While this process works in many children there are concerns about safety, feasibility and drop-outs and how to adapt protocols for multiple allergies. Many OIT trials have targeted approximately 4000mg of single food/day. In these trials up to 40% drop-out. There is evidence much lower doses can have beneficial effects. The investigators will evaluate if low doses of foods can allow for OIT to multiple foods. This approach may have efficacy against accidental exposure and be able to demonstrate immune changes. This approach may have a low burden of treatment and a low rate of allergic reactions and
There is growing evidence that microbial programming beginning in-utero can be a central component for a balanced development of innate immunity and optimal growth and development in newborns. However, the specific types of bacteria along with their cross-talk with maternal and fetal host factors are far from being clear. The investigators hypothesize microbial compositions at different body sites of pregnant women are associated with early-life microbiota of their offspring as well as growth, neurodevelopment and the development of allergic and neurocognitive disorders. This is a prospective birth cohort study involving Chinese mother-child pairs. The investigators will follow up 120 pregnant women from first trimester until childbirth, and the child until three years of age.
The study determines how a 6 months oral immunotherapy (OIT) program with hen's egg (HE) effects cellular and humoral immune responses in 50 children with HE allergy. Clinical data, transcriptomics and epigenetics are combined and analyzed by advanced system biology methods. This study will provide better understanding of the effects and mechanisms of OIT.
This is a 2:1 randomized, double-blind, placebo-controlled, multi-center, phase III clinical study evaluating the efficacy and safety of ZL-2306 (niraparib) for maintenance treatment in patients with platinum-sensitive relapsed ovarian cancer, fallopian tube carcinoma or primary peritoneal cancer (collectively referred to as relapsed ovarian cancer).The evaluation will be divided into two stages: Stage I will be conducted in all patients, and if the predetermined statistically significant difference is not reached, the trial will continue to extend to Stage II during which evaluation will be performed in gBRCA mutation-positive ovarian cancer patients.
This phase I trial studies the best dose and side effects of NY-ESO-1 T cell receptor (TCR) engineered T cells and how well they work with NY-ESO-1 TCR engineered hematopoietic stem cells (HSCs) after melphalan conditioning regimen in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that has come back (recurrent) or does not respond to treatment (refractory). The melphalan conditioning chemotherapy makes room in the patient's bone marrow for new blood cells and blood-forming cells (stem cells) to grow. Giving NY-ESO-1 TCR T cells and stem cells after the conditioning chemotherapy is intended to replace the immune system with new immune cells that have been redirected to attack and kill the cancer cells and thereby improve immune system function against cancer. Giving NY-ESO-1 TCR engineered T cells and HSCs after melphalan may work better in treating patients with ovarian, fallopian tube, or primary peritoneal cancer.
