Childhood Allergy and the Neonatal Environment

The purpose of this research study is to study the relationship between childhood asthma, allergies, and early-life environmental factors that may cause childhood asthma and allergies. Previous birth cohort studies have found early-life environmental factors such as allergies, pollutants, viruses and bacteria have all contributed to the development of asthma and allergies. Investigators are doing this research because there continues to be a strong need to understand the root causes of asthma and allergies. The CANOE study is an observational cohort study, which means investigators are not asking participants or participant's child to change their medications and investigators will not be giving participants or participant's child a study drug.

Tromsø Birch Rust Allergy Study. Allergy to Birch Rust, a Possible Explanation to Seasonal Airway Allergy During Autumn?

In this project we study if spores from birch rust fungi (Melampsoridium Betulinum = MB) may be the eliciting allergen in patients with seasonal airway allergy during autumn in North Norway. Patients with suspected allergy to MB are compared with non-allergic controls using data about allergic disease and daily allergic symptoms during autumn. Daily spread of MB spores are compared with daily variations in allergic symptoms. Sensitization to MB and MB allergy are tested with skin prick test, specific immunoglobulin E (IgE) in serum, nasal provocation test and basophil activation test (BAT).

Cognitive Behaviour Therapy for Adults With Allergy.

People with severe allergy often experience distress but research exploring psychological interventions for them is limited. Cognitive Behaviour Therapy (CBT) is routinely used in NHS services. The research investigators would like to know whether a short term CBT group is feasible and acceptable for those with severe allergy who are also experiencing distress and/or anxiety. The research investigators will recruit people with allergy through support groups and social media. Those interested in the study will be invited to complete a screening interview. If the participants meet the inclusion criteria and consent to take part the participants will be randomly allocated into the CBT or a self-help group. Full written consent will be needed at the telephone screening session if participants are eligible for the study. Participants will be given time to complete this prior to the intervention. Participants will be able to withdraw at any point during the study. The self-help group will be sent self-help materials. The CBT group will attend a single session day workshop based on CBT (maximum 6 hours length). Due to the Covid-19 pandemic, the workshop may need to be delivered online. If delivered online, the workshop may be delivered over two three hour sessions. Participants will be asked to complete questionnaires at baseline, the day of the intervention, one month later and three months later. They will be asked to complete a feedback form about their experiences in the group and at three month follow up, a small subsample of participants will be invited to interview. Once the data is analysed it will be written up into a report for a clinical psychology doctoral qualification major research project. It may also be published in academic journals and presented at conferences. A possible outcome of the research is that people with allergy either do or do not find the workshops an acceptable and/or feasible intervention. It will identify the potential for this intervention to reduce distress and anxiety and to improve coping skills in adults with allergy. Those who take part are welcome to contact the researchers to find out the results of the study.

Safety and Efficacy of Intracanalicular Dexamethasone Compared to Loteprednol Etabonate in Patients With Keratoconus

Drug delivery platforms are an innovative exciting advancement in ophthalmology. They allow patients to eliminate topical medications which are generally associated with lack of compliance, difficulty of use and requiring help from family members. These delivery systems can be applied easily in office, and patients do not have to worry about drop insertion in their post-operative regimen. The results of this research project should help to answer the following question: Does the use of a physician administered intracanalicular dexamethasone insert improve the signs and symptoms of ocular allergy and dry eye disease in KC patients compared to the use of topical loteprednol etabonate ophthalmic gel 0.38%?

Microbiota and Allergy

Food allergy derives from a dysregulation of oral tolerance mechanisms. Studies suggest a crucial role for gut microbiota in oral tolerance development. An altered composition of gut microbiota 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. Preliminary results of MATFA study demonstrated gut microbiota in allergic children.These findings support the pivotal role of the gut microbiota in the pathogenesis of allergic diseases and may open new strategies in the development of innovative preventive and therapeutic approaches.

Pilot Study: Characterization of the Immune Phenotype of Patients Allergic to Wasp Venom or Penicillin

Severity of allergic reactions are highly variable from one individual to another, they can range from absent to life threatening. Allergic manifestations and specifically those of anaphylactic reactions are generally attributed to an IgE-dependent activation of mast cells and/or basophils followed by the release of histamine. Recently however evidence accumulated that other pathways might similarly contribute or even trigger anaphylaxis. Moreover, while the variance in human populations is an important subject to scientific research, medical practices and public health policies typically take a 'one for all' approach to disease management and drug development. Indeed, individual heterogeneity in the immune response can have a big impact on the likelihood to respond to therapy. Because of the complexity of immune responses in the individual and within the population, it has not been possible thus far to define the parameters (genetic or environmental) that define the immune system of allergic patients and its natural occurring variability. Thanks to the efforts that have been made in the framework of the Labex "Milieu Intérieur" study genetic, immunological and environmental factors have been identified that can be linked to the heterogeneity of immune responses in healthy individuals. By comparing these already available data from healthy individuals to a novel cohort of patients with defined severe allergic manifestations, we will be able to identify for the first time immunological and environmental parameters that are common to patients with severe allergies and identify those parameters that distinguish allergic patients from the healthy donor cohort. This analysis will thus open new perspectives on deregulated immune pathways in allergic patients allowing to orient future treatment approaches. Furthermore, comparing immune responses before and after allergen-specific immunotherapy will help understanding, which changes in immune responses are causal to a successful treatment. Importantly, this analysis will shed light on the individual differences that may predict the outcome of treatment approaches and propose novel markers of its success.

Skin Barrier Assessment in Pregnancy and at Birth

This is a prospective birth cohort study assessing the role of maternal and environmental factors on the development of allergic diseases in children. Pregnant mothers will be enrolled and we will examine her skin barrier with skin tape strips (STS) and transepidermal water loss (TEWL), along with blood work. We will then follow her offspring and perform similar testing, along with detailed questionnaires inquiring about exposures such as use of detergents and soaps, sunlight exposure, and pollution exposure. When the infant is around 12 months old, we will contact the family via telephone to see if the child developed any allergic conditions within their first year of life, such as eczema, food allergy, or wheezing. A final questionnaire will be performed.
