Children, allergy, diet and environment

Around 30% of children suffer from allergies nowadays. These often start with so-called “childhood eczema”– neurodermatitis – as early as infancy. The symptoms of allergy sometimes disappear, but sometimes the condition deteriorates and additional symptoms occur, i.e. hay fever, asthma and food allergies may develop.

What prevents an allergy from developing in childhood?

This key question is being addressed in a CK-CARE research project. Why does our immune system develop a misdirected inflammatory reaction to harmless substances that surround us every day and actually do us no harm? Our modern lifestyle certainly encourages allergy development – that much is known. Our diet, the move away from an agricultural way of life, excessive hygiene, the use of pharmaceuticals, etc., all combine as contributory factors. However, diet in very early childhood plays a crucial role in whether or not a person develops an allergy, as discovered by CK-CARE – and other research teams worldwide. Hence the digestive has a decisive part to play. As knowledge in this field is still very limited, CK-CARE is conducting what is known as an observational study on the development of allergy in childhood.

Children are being observed from newborn infants up to 3 years of age: this includes keeping a “food diary”, investigating the environmental conditions and regularly checking the children for allergy symptoms. Microbial colonisation of skin, throat and bowel is identified and the function of the immune cells in the body is analysed. Breath tests are carried out and breastmilk is tested. The completed questionnaires are scanned, the data are exported, then transferred in anonymised form to the central CK-CARE study database.

Targeted laboratory testing of substances that might suppress allergies
​Based on early research work, it was possible to treat allergies with short-chain fatty acids (e.g. ingredients of butter). In collaboration with the SIAF, Davos, the team has now investigated in the laboratory whether treatment as early as pregnancy might be helpful. In addition, experiments are being conducted to study a potential effect of these fatty acids on inflammation of the bowel.

20th CK-CARE Team Meeting 2025

The 20th CK-CARE Team Meeting took place on 24 and 25 February 2025 under the motto ‘Embracing the concept of data analysis to further personalised patient care’. The aim of the meeting was to develop innovative ideas and prepare a draft publication for the CK-CARE Scientific Board based on the data from the CK-CARE registry and biobank. The event began with an informative presentation of the data from the CK-CARE repository and the biobank, which provided the framework for intensive group work. The participants were divided into four teams: Team 1, 2 and 3 chose the topic according to their personal interest based on the available data from the CKC repository and the biobank, while team 4 focused on science communication for the NIA app. The day was rounded off with a guided tour of the historic Fuggerei in Augsburg followed by a tapas dinner at the Tafeldecker restaurant, which provided space for lively discussions. On Tuesday, each group presented their idea in a 3-minute ‘Scientific Paper Pitch’ to the critical members of the ‘CK-CARE Scientific Board-lion’s den’.

Global Allergy Forum 2022

The 4th Davos Declaration: A Milestone for Atopic Dermatitis Patient Care

During the last Global Allergy Forum (GAF) key opinion leaders from science, medicine and industry met in Davos to discuss the current state of the art of patient care in atopic dermatitis (AD) and proposed new strategies for its improvement. The thinktank addressed the high prevalence of AD and strategized methods to advance research, diagnostics, management and prevention. The findings are now published as «Navigating the Evolving Landscape of Atopic Dermatitis: Challenges and Future Opportunities: the 4th Davos Declaration».

Annual Report CK-CARE 2023

CK-CARE’s work has global resonance and, thanks to this strong position, significant projects in clinical allergy research were again launched or catalysed in the reporting year. CK-CARE’s working methods were sharpened in terms of medical translation and a strengthening of research capacities on the medical campus in Davos was defined in order to increase CK-CARE’s performance.

Kühne-Foundation Annual Report 2023

“Entrepreneurial success should go hand in hand with the promotion of  the common good. The Kühne Foundation fulfills this task. With a variety of programs and projects, the founder and the Kühne Foundation also assume their socio-political responsibility.”

The activities were significantly expanded, particularly in the area of logistics. In addition, the new focus area of climate action was established, and the first projects were launched.

How flexible are neutrophils to opposing signaling?

Paola Martinez Murillo a postdoctoral researcher in Pierre-Yves Mantel’s group from CK-CARE obtained a Spark grant from the SNSF to investigate the effect of opposite signals on neutrophil biology in atopic dermatitis.

Spark is a Swiss National Science Foundation (SNSF) funding scheme aiming to support projects that show unconventional thinking and introduce a unique approach. The Spark is highly competitive and supports projects based on promising ideas of high originality. CK-CARE was recognized as an eligible institution in June 2023 by the SNSF, opening new funding opportunities for the CK-CARE researchers.

This project aims to understand how two opposing signals: eczema dysregulated immune environment (Th2 response) and bacterial colonization (Th1 response) impact neutrophils function.

Neutrophils are tiny but powerful immune cells in our blood that fight off bacteria and viruses. They live for only 2-3 days and can quickly respond to infections. Neutrophils can adapt to different situations thanks to their genetic instructions (RNA). Our body’s reversible changes in reading DNA, called epigenomic modifications, are crucial for a functional immune response.

Eczema, a chronic skin condition, happens when various factors like genetics, skin damage, and immune reactions go haywire. People with eczema have neutrophils that do not work as well in fighting bacteria, making them more prone to infections.

This study addresses a knowledge gap in neutrophil adaptation to an allergic milieu, by evaluating neutrophil adaptation to anti-bacterial response in a type 2 immune response dominated context such as atopic dermatitis using transcriptional and epigenomic profiling along with comprehensive analysis of neutrophil functionality (netosis, phagocytosis, ROS-production, bactericidal activity, chemotaxis). Building upon in-vitro stimulation insights, then we will aim for a comprehensive analysis of neutrophil functionality in atopic dermatitis patients treated or not with Dupilumab.
