Filter by:Egg allergy is common in early childhood, affecting at least one in 50 preschool children. Influenza ("'flu") vaccines contain egg protein, as the vaccine is cultured in hen's eggs. There is robust data to support the safety of influenza vaccines (containing low or negligible amounts of egg protein) in patients with egg allergy. A new influenza vaccine, known as LAIV (Live Attenuated Intranasal Vaccine) has recently been approved by a number of licensing boards and is given by a spray into the nose. This new vaccine has been available in the United States for several years and is highly effective and against influenza infection, with an excellent safety profile in children without egg allergy. However, LAIV is also grown in hen's eggs and contains egg protein, and there are NO published data on the safety of LAIV in egg-allergic children. In SNIFFLE 1 Study, 433 doses were given to 282 egg-allergic children; data is currently being analysed. The objective of this multicentre study is to further assess the safety of intranasal LAIV in egg-allergic children, in order to demonstrate that these children can safely be given the new LAIV within a primary care health environment.
The purpose of this study is to determine whether DCVAC/OvCa added to chemotherapy (carboplatin and gemcitabine as second line chemotherapy) may result in prolongation of progression free survival (PFS).
The purpose of the study is to determine whether therapeutic education can improve the quality of life of the child from 8 to 12 years old suffering of food allergy. This study also show us if therapeutic education has an effect on the quality of life of child's family.
Determine whether peanut oral immunotherapy (OIT) induces clinical tolerance as assessed after the initial 3 month avoidance period Secondary Objectives: - Identify the basic immune mechanisms which can explain the differences in the effects of OIT in desensitized vs. tolerant individuals. - Determine whether immune monitoring measurements reflecting underlying mechanisms during OIT can be used to predict responses to OIT in individual subjects and, ultimately, to improve the safety and efficacy outcomes in peanut OIT protocols.
This is an open-label Phase 1b dose-escalation study to assess the safety, tolerability, and PK of OMP-54F28 when combined with paclitaxel and carboplatin. OMP-54F28 will be administered IV on Days 1 of each 21-day cycle. Paclitaxel (175 mg/m2) and carboplatin (AUC = 5 mg/mL • min) will be administered IV on Day 1 of each cycle. A total of 6 cycles of paclitaxel and carboplatin will be given. Additional cycles may be given as per institutional standard of care after discussion with the Medical Monitor. Treatment with OMP-54F28 will continue after completion of treatment with paclitaxel and carboplatin. The planned dose levels of OMP-54F28 are 5 and 10 mg/kg.
Food allergy (FA) derives from a dysregulation of oral tolerance mechanisms. Studies suggest a crucial role for enteric microflora in oral tolerance development. An altered composition of intestinal microflora results in an unbalanced local and systemic immune response to food allergens. There are qualitative and quantitative differences in gut microbiota composition in children with food allergy. These findings support the concept that specific beneficial bacteria from human intestinal microflora, designated probiotics, could restore intestinal microflora homeostasis and prevent or treat FA.
Egg, milk and cereal allergies are the most important food allergies in Finnish children, the prevalence in western countries is 1-4 %. In some individuals food-allergy is maintained in to adulthood. Recent studies suggest that specific oral tolerance induction (SOTI) provides a treatment option in children with continuing allergy with high success rates. The study aims at specific oral tolerance induction in adults allergic to cow's milk or hen's egg. Oral immunotherapy involves taking very small amounts of the allergen, and slowly increasing the amount. Consequently, an elimination diet may be wholly or partially cancelled, without the fear of serious allergic reactions. Another aim is to explore changes in antibody-mediated and cell-mediated immune response to individual components of cow's milk and egg allergens during tolerance induction and compare these with the effect of the treatment.
Cow's milk allergy is the most common food allergy in children. The scenery clinical and epidemiological of cow's milk allergy is significantly changed in the last decade. The severity of the clinical manifestations is still rising, and now cow's milk allergy has become the leading cause of hospitalization for food -induced anaphylaxis in our country. In addition, the overall prevalence of cow's milk allergy is increasing for a gradual reduction in the ability to acquire immunological tolerance to cow's milk protein in the first years of life. These mutations dictate the need to identify strategies to stimulate the acquisition of immunological tolerance in children affected by cow's milk allergy . The mechanisms of acquired immunological tolerance are not yet fully defined . The current view suggests the existence of a dynamic mechanism , consisting of various cellular compartments , which is set in a crucial environmental factors arising mainly from the diet and its effects on the intestinal microbiota. These acquisitions have contributed to the definition of a new concept in the field of human nutrition: immunonutrition. The immunonutrition is the ability, through the intake of specific nutrients on the immune system to interfere directly or indirectly through modulation of the composition and function of the intestinal microbiota. The proponent group has recently shown that it is possible to stimulate a more rapid acquisition of immunological tolerance in children affected by CMA through the administration of extensively hydrolysed casein containing the probiotic Lactobacillus rhamnosus GG (LGG) (Berni Canani et al. J Pediatr 2013) . Several lines of evidence suggest that this effect is induced by a combination of direct immunomodulatory action exerted by some small peptides derived from the beta - casein and the action of lactobacillus GG. It 's well known that the Lactobacillus GG is able to adjust the composition and functions of the microbiota in the child with CMA and directly adjust some immunological mechanisms involved in the pathogenesis of this condition. At the same time other groups have demonstrated the possibility that a high percentage of patients with IgE-mediated CMA is able to tolerate foods containing hydrolyzed cow's milk proteins with different processes. It has also been speculated that these strategies can facilitate the acquisition of immune tolerance in patients with cow's milk allergy. One of these foods is Parmigiano -Reggiano cheese, which is characterized by an ' extensive hydrolysis of the proteins in cow's milk , which degrade the caseins present and generate large amounts of peptides and free amino acids and by the presence of appreciable quantities of Lactobacillus GG in the samples to maturing higher . In a recent study it was shown that 58% of patients suffering from IgE-mediated CMA is able to tolerate a daily intake of normal amounts of this food , especially in the absence of a sensibilization to IgE specific to the beta lactoglobulin. These new findings allow us to hypothesize the use of Parmigiano REggiano cheese as a possible strategy immunonutrition can stimulate the acquisition of immune tolerance in patients with CMA .
This is a follow-up cohort study of 6 years old children born preterm in Denmark from 2004-2008, and at four different neonatal units. During hospitalisation they received breast milk with fortification. At time of discharge there were made 3 different nutrition groups; if possible they were randomised into one of two groups: 1. Breastfeeding solely 2. Breastfeeding with fortification If breastfeeding was not possible they were put in group 3 and were bottle fed with: 3. Preterm formula This nutrition intervention went on for 4 month. At the age of 6, the children will be invited to come for an ambulant control and other examinations regarding growth, allergy and metabolic syndrome.
Purpose: The proposed research, if successfully implemented, will result in a low-dose, low-cost, and highly effective method for screening of lung cancer, leading to reduction of the lung cancer mortality rate. Using the stationary Digital Chest Tomosynthesis (s-DCT) system the imaging dose for a full tomosynthesis scan is expected to be only 10% of that from a low-dose computed tomography (CT). The targeted imaging time of 2s is 1/5 to 1/3 of that from a current commercial digital chest tomosynthesis (DCT) system at the same imaging dose. Beyond lung cancer screening, the low-dose and sensitive 3D lung imaging modality will likely to find applications in areas such as monitoring of pediatric cystic fibrosis patients where reduction of imaging dose is critical. Participants: One hundred (100) patients undergoing a clinical non-contrast CT for their lung nodules will be asked to have this procedure (scan) within 2 weeks (+/- 1 week) of their clinical CT and chest radiograph, with no intervening procedures or therapies. Procedures (methods): The purpose and endpoint of this study is to compare the sensitivity of the s-DCT system to the conventional chest radiographs with non-contrast chest CT as the reference standard. One hundred (100) patients undergoing a clinical non-contrast CT for their lung nodules will be asked to have this procedure (scan) within 2 weeks (+/- 1 week) of their clinical CT and chest radiograph, with no intervening procedures or therapies.
