Filter by:The purpose of this study is to examine the effect of nursing intervention to regulate the home environment on symptom control and quality of life in children with allergic rhinitis.
A validated mobile Allergen exposure chamber (AEC) is used to expose qualified study participants suffering from house dust mite (HDM) induced allergic rhinoconjunctivitis. A maximum of four individuals are exposed at a time under standardized conditions with a mixture of allergens from Dermatophagoides pteronyssinus and Dermatophagoides farinae (each 50%, faeces and body allergens; doses of 250 μg/m3 air; 21°C, and 55% relative air moisture). After the first exposure, a dietary supplement lozenge, containing beta-lactoglobulin (BLG), iron, retinoic acid, zinc and polyphenols, is taken twice daily for a period of 12 weeks, followed by the second exposure. A minimum of thirty persons are challenged with HDM allergen. After entering the chamber there is an acclimatization phase of 20 minutes with no exposure. Exposure time starts after acclimatization in the chamber and is 120 minutes at each visit. Objective parameters are recorded every 30 minutes, and subjective parameters are recorded every 10 minutes over a period of 120 minutes. During the exposure a plateau (steady-state) of total nasal symptom score with a difference from baseline is measured in all participants for each of the two exposures with HDM.
This project consists of a psychological intervention in patients and their families with different chronic diseases in order to carry out a comparative study between medical pathologies to know which are the protective or risk variables for the adaptation to the disease.
40 allergic rhinitis patients in the acute phase will be enrolled in the study. All the allergic patients should be confirmed those who are over 20 years old and hypersensitive to house dust mite allergens confirmed by MAST test before study. All patients were treated with mixed formula of Chinese medicine for one months.
This study aims to investigate immune mechanisms and phenotypes and endotypes of allergic airway diseases - allergic rhinitis and allergic asthma. Pathogenesis of these diseases are not fully investigated yet. Patients with the same disease have different dominant symptoms, course of the disease and response to treatment. Moreover, there is a hypothesis about united airway disease suggesting that allergic rhinitis and allergic asthma is different manifestation of the same disease. This led to assumption of phenotypes and endotypes. This classification which still is not unified can let to prescribe personalized treatment for every patient.
52 patients that had previously participated in the RDBPC study of intralymphatic immunotherapy (ILIT) with 2 concomitant allergens, birch and grass, with NCT02423707, were eligible for an open follow up 5-6 years after treatment.
This study evaluate the efficacy of Polyvalent Mechanical Bacterial Lysate (PMBL - Ismigen) to improve the clinical course of grass pollen-induced allergic rhinitis (using: TNSS, TOSS, VAS, PNIF) in children aged 5 to 17. Half of the 70 participants will receive PMBL while the other half will receive placebo.
In this study researchers want to learn how quickly patients suffering from allergic rhinitis (also known as hay fever) can expect symptom relief after using Azelastine Hydrochloride 0.15% Nasal Spray. This study plans to enrol about 80 male or female participants in the age of 18 to 65 years suffering from an allergic rhinitis to ragweed pollen for at least 2 years. In a first phase participants will be exposed to ragweed pollen in a special study room to ensure they will be adequately symptomatic when they progress into the treatment phase of the study. In a second phase study participants will be divided in 2 groups. After exposure to ragweed pollen one group will receive Azelastine Hydrochloride 0.15% Nasal Spray and the other group will receive placebo (a nasal spray which does not contain any active drug substance). In the third phase of study the treatment will be switched: participants who received in the previous study Azelastine Hydrochloride 0.15% Nasal Spray will receive the nasal spray without any active drug substance and the other group will receive Azelastine Hydrochloride 0.15% Nasal Spray. During the second and third study phase the researchers will examine thoroughly over 4 hours the change of nasal symptoms such as runny nose, itchy nose, sneezing and nasal congestion after participants received the nasal spray.
This study series consists of four related studies and aims to explore and describe many important elements of alopecia areata over three key areas: (1) the current epidemiology of alopecia areata, (2) the prevalence and incidence of psychiatric co-morbidities in people with alopecia areata, (3) the prevalence and incidence of autoimmune and atopic conditions in people with alopecia areata, and (4) the incidence of common infections in people with alopecia areata.
Adults with known respiratory allergy/asthma with known skin test sensitization will undergo repeat skin prick testing at 4 areas of both arms (bilateral forearms, bilateral upper arms). Each site will be challenged with up to three known allergens, saline and histamine controls. Mean wheal diameter after 20 minutes challenge will be determined. This is followed by placement of minocycline cream (0%, 1%, 2%, 3%), placed in randomized fashion at each of 1 of 4 skin test sites. Measurement of subsequent wheal diameter will be done at 30 minutes, 60 minutes and 24 hours.
