Filter by: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.
AsthmaVent is a multi-center study, investigating the association between indoor air quality and childhood asthma. In Denmark, we spend more and more time indoors. Our houses are built airtight to save energy and are difficult to ventilate. We are thus more exposed to our indoor air than ever before. We know that indoor air contains many different components that can affect our airways inappropriately and particularly children with asthma, who have sensitive airways are sensitive to these components. The AsthmaVent project examines whether increased ventilation is able to improve the indoor environment to such an extent that the asthma disease control, for children with asthma and house dust mite allergy improves, resulting in need for less medication. Previous studies have pointed towards a beneficial effect of mechanical ventilation, on both the indoor air quality and on children's health and quality of life. There is not currently a consensus in this area, as studies so far have not been large or good enough to confidently determine the effect. This project is big and is designed so that it takes into account the sources of error seen in previous studies on the topic. We include, over a 3-year period (2012-2014), a total of 80 children with asthma and house dust mite allergy aged 6-18 years, from pediatric departments in Aarhus, Odense, Kolding, Randers and Herning. They are divided into two groups, receiving either active ventilation or placebo ventilation, meaning a non-functioning ventilation system that just recirculates the air in the room. Ventilation systems are installed in the fall and winter and ventilate the child's bedroom during 9 months. Indoor air quality and asthma control are assessed every 3 months, both at home visits were air quality and allergen levels of house dust mites are studies and at visits to the outpatient clinics with control of asthma parameters and quality of life. The project involves collaboration between several institutions with an interest in indoor air quality in relation to allergies and asthma and with great expertise in the field.The project was initiated by CISBO (Centre for Indoor Environment and Health in Dwellings), a center consisting of several institutions in Denmark dealing with indoor environment: Department of Public Health at Aarhus University and University of Copenhagen, Danish Building Research Institute and the Technical University of Denmark. Since asthma is the most common chronic childhood disease in Denmark and since the development of allergies and asthma has high social and personal costs, it is important for both society and the individual family, to find out whether simply improving the indoor air quality by increased ventilation can lead to an improvement in asthma disease control.
The aim of the intervention is to examine the effect of the bacterial strain BB-12, provided for 6 mo, on the prevalence of infections and allergic manifestations in small children, and how BB-12 affects the immune system, the gastrointestinal tract and the microbiota. Children are enrolled during 2 winter seasons.
Food allergy is a potentially life threatening condition. The current practice consists of elimination diet and injectable epinephrine in case of a reaction. Recently, oral immunotherapy has emerged as a treatment for food allergy in milk eggs and peanuts. We conduct an oral immunotherapy program with ~500 patients so far. In this study we intent to follow patients who completed the program and assess their allergy status and quality of life.
A Phase III study to determine the sensitivity and specificity of three solutions of different allergen extracts for diagnosis by skin prick-test: - 5 Grasses pollen, - Birch pollen, - Dermatophagoides pteronyssinus mite
The respiratory epithelium plays a leading role in the development of allergic respiratory disease with barrier function alteration, its repair mechanisms, of anti-viral fight and the ability to induce by itself Th2 responses. The majority of allergic asthmatic patients have reached concomitant ENT: the concept of "one airway, one disease." Access to this material of epithelial study in the different phenotypes of the disease appears to be crucial. Nasal and bronchial epithelial tissues reveal essential differences in particular related to their environment (remodeling less intense and a lower sensitivity to the virus in the nose), but they nevertheless share many common cellular characteristics.
The primary objective of the study is to assess the safety and tolerability of single ascending doses of subcutaneously (SC) administered REGN1908-1909 in allergic, adult subjects.
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 Cumulative Patch Test with a Challenge Phase is a test devised to ascertain if a chemical agent or agents have the potential to cause contact irritation or contact allergy in the skin. Allergy is only elicited in immunologically competent individuals who have become sensitized through exposure to the chemical agent at a sufficient concentration and for a sufficient duration of time.
The purpose of the study is to determine if any of Mother's Choice' all-natural personal-care products cause either irritation or allergic reaction when applied to both normal or sensitive skin. Each product will be tested on the skin using patch tests.
