Allergic AsthmaAllergic Rhinitis1 more

The prevalence of allergic diseases (atopic dermatitis, asthma, rhinitis, conjunctivitis and food allergy) has increased dramatically in industrialized countries over the last 20-30 years. Allergic diseases are present especially in children and young adults, but all age groups are affected, with variations across countries and age. To propose new therapies, the investigators must first understand the physiopathology. Since their discovery the regulatory T cells have continued to be the subject of work to understand their role in maintaining immune homeostasis in the human body but also their involvement in autoimmune diseases, inflammatory diseases, transplants of solid organs or fluids and allergic diseases. It was identified two broad classes of regulatory T cells: T cells = natural regulators acquisition of a phenotype and a regulatory function right out of the thymus ( CD25 + / CD127 + low / FoxP3 +). T cells induced regulators = acquisition of a phenotype and a regulatory function on the periphery depending on the cytokine micro-environment. Phenotypic characterization of these is less obvious and even more so than during the last ten years several induced regulatory T cell populations have been described ( eg, Tr1 ). A new subpopulation of T cells induced in patients with inflammatory bowel disease recently identified have a particular phenotype as bearing the CD4 and CD8 double marking with a regulatory phenotype. These regulatory T cells are also induced a specific of a commensal intestinal bacterium (Faecalibacterium prausnitzii). Regarding allergies, it has been widely demonstrated a relationship between changes of the intestinal microbiota and the occurrence of allergic diseases. The investigators would therefore propose a cross-sectional study, single-center, controlled, single blinded to study the role of T cells called double positive induced regulators DP8 to compare the frequency and the regulatory function of specific DP8 of Faecalibacterium prausnitzii in atopic dermatitis, asthma and allergic rhinitis compared to control samples.

Allergic RhinitisAsthma

"Studio Nava" is a National Study aiming to assess allergic rhinitis and asthma outcomes on Quality of Life and Quality of Sleep in adolescent patients by means of Web Survey. "Studio Nava" also proposes the innovative use of a web platform ("http://nava.ibim.cnr.it/") that contains all standardized tools (medical-healthcare web form, ACT, Asthma control test; PSQI, Pittsburgh Sleep Quality Index; T5SS, Total Symptom Score; modified SIDRIA for adolescents; Rhinasthma; VAS scale), that will be available for the doctors after the registration to the web platform. Downloaded questionnaires will be delivered to case-patient, asking him/her to fill them during the waiting time of the visit.

Prevalence of Nasal Hyperreactivity in Chronic Upper Airway Inflammation

HyperactivityChronic Rhinosinusitis (Diagnosis)2 more

Rhinitis, or inflammation of the nasal mucosa, can present with nasal obstruction, nasal discharge, itch or sneezing. If the sinusal mucosa is involved as well, it is called rhinosinusitis and facial pain or loss of smell is possible. Several causes are known, such as an underlying allergy ("allergic rhinitis", AR). If at least 2 symptoms are present for at least 12 weeks, it is called "chronic rhinosinusitis" (CRS). Up to 2/3 of the AR and CRS patients have symptoms upon exposure to triggers such as sudden temperature changes, smoke, fragrances… a phenomenon called "nasal hyperreactivity" (NHR). It is currently not clear why some patients suffer NHR while others do not. In this study, the investigators want to determine the prevalence and severity of nasal hyperreactivity in patients with chronic upper airway inflammation. To this end, patients and healthy controls will be asked to fill out a questionnaire inquiring presence and severity of nasal symptoms upon exposure to particular environmental triggers.

EczemaAsthma1 more

This study aims to document prospectively the incidence of allergies of eczema, asthma and allergic rhinitis in 2 diverse cohorts (Singaporean and Indonesian) with contrasting lifestyles and socioeconomic development. The profile of microbial colonization in terms of species variety, as well as their genetic diversity will be studied in Singapore and Indonesia cohorts and to correlate these with clinical allergy.
