Active clinical trials for "Hypersensitivity"

Brief Summary: This study aims to investigate whether protein fortification of beverages causes mouthdrying and mucoadhesion and whether this is influenced by saliva flow.

Aluminium is used in many different cosmetic products, including make-up, deodorants and sunscreen. The purpose of this study is to investigate whether these everyday skin products with small amounts of aluminium can cause skin reactions in children diagnosed with contact allergy to aluminium. The study is conducted as a Repeated Open Application Test study (ROAT), a method originally developed to clarify the clinical relevance of questionable and positive patch samples, by imitating everyday use of a skin product.

Ultravist is an iodine-based contrast agent that helps to make medical imaging scans clearer. It is also called iopromide, and it is available for doctors to give patients before they have scans. Even after a treatment or substance has been approved for use, researchers continue to study it to learn more about its safety. Researchers have done studies on the safety of Ultravist, but they want to learn more about specific medical problems called hypersensitivity reactions (HSRs). These are undesirable immune system reactions to the study drug. In this study, the researchers will compare the risk of HSRs in children and in the elderly to the risk of HSRs in middle aged adults. The researchers will look at information about medical problems that happened in people in 4 other studies. These studies are called PMS I, IMAGE, TRUST, and Ultravist in CT. A total of about 139,000 people will be included in this study. All of the people in the earlier 4 studies received Ultravist as an injection into the vein or artery before having a scan. In this study, the researchers will compare the number of children, middle aged adults, and elderly patients who had HSRs after receiving Ultravist.

This is a single-centre phase I study to assess the Drug-Drug Interaction potential of MLC1501 with a cocktail of drugs acting as sensitive clinical probe substrates of Cytochrome P450 isoenzymes and Transporters in healthy subjects . The study will have 2 cohorts, one for the CYP study and the other for the Transporters study. Eligible subjects (n=24) will be assigned to one of the 2 cohorts in a 1:1 ratio.

The aim of the study was to describe an intensive ultra rush (UR) protocol of raw Golden apple (RGA) reintroduction in 28 in-patients, show the protocol's tolerance and the patients' follow-up at 2 months and 1 year. Patients with oral allergic syndrome (OAS) having resulted in raw fruits eviction were admitted to day hospital between June 1 2016 and October 31 2017.

The aim of this 11 study analysis was to compare the effect of bioavailable stannous fluoride (SnF2) on dentine hypersensitivity versus a positive or negative control dentifrice.

Objective Seasonal allergic rhinitis (SAR) is a common disease in childhood and characterized by type 2 inflammation, bothersome symptoms, and impaired quality of life (QoL). Intranasal corticosteroids are effective medications in managing SAR patients. In addition, mometasone furoate nasal spray (MFNS) is a well-known therapeutic option. However, the literature provided no data about its effects in European children with SAR. Thus this study addressed this unmet need.

Application of artificial intelligence deep learning algorithm to analyze the relationship between hormone sensitivity of idiopathic interstitial pneumonia and imaging features of high resolution CT.

The investigators wish to evaluate the association between tryptase values as well as c-Kit mutation and adverse effects in the course of immunotherapy. The investigators also intend to assess the effect of immunotherapy on tryptase levels.

This is a pilot trial in cat allergic participants, designed to compare allergic responses in each participant to a specific allergen by two methods of exposure. The methods of exposure to be used are: the environment exposure chamber (EEC) and nasal allergen challenge (NAC). Potential participants will be screened for evidence of cat allergy. Participants with a range of allergic sensitivities to cat allergen will be enrolled. To help ensure some breadth in the level of allergic sensitivity among participants, individuals with both high and low exposures to cat allergens in their daily lives will be enrolled.
