Active clinical trials for "Hypersensitivity"

Study objectives Primary objective: This study wants to evaluate the safety of a latex safe protocol as proposed by the Australasian Society of Clinical Immunology and Allergy. In other words,the investigators hope to demonstrate that patients with known latex allergy or latex sensitisation can be treated safely in operating theatres without special requirements towards scheduling provided that all powdered latex gloves are removed from the OR environment( preparation rooms, theatres, recovery room and surroundings). In contrast, earlier guidelines require the theatre to be left unused during at least 3 hours before a patient with suspected latex allergy can be operated on in this theatre. Secondary objectives: The investigators want to evaluate to what extend patients who report a latex allergy show risk factors of latex allergy. To investigate to what extend latex allergy was proven by laboratory testing or skin testing in patients who report a latex allergy. Type of latex allergic reaction when patients report a latex allergy. The level of satisfaction of surgeons and OR scheduling staff with the new latex safe protocol and with the switching to powder free latex gloves.

Assessment of the knowledge levels of restaurant personnel about food allergies. A structured questionnaire was given through a telephonic interview to evaluate the responses of the respondents.

This is a prospective observational study , to clarity the characteristics of airway inflammation, airway reactivity and airway resistance in rhinitic children with or without asthma and to explore the possible predictors in the progression of allergic rhinitis to asthma.

"Troponin T (TnT) is a component of the contractile apparatus of the striated musculature. Although the function of TnT is the same in all striated muscles found in the heart to form a TNT (cardiac TnT) differing significantly TnT of the skeletal muscles. Because of its high tissue specificity, cardiac TnT is a specific marker and highly sensitive of myocardial injury. Asymptomatic elevations of troponins is frequently found in patients with chronic renal failure in stage V, which present no clinical signs of acute or electrical myocardial injury. Many studies have been conducted in recent years to explain the origin and clinical significance of this elevation, but the results are controversial: cardiac dysfunction, left ventricular hypertrophy or chronic inflammation. Besides the effect of the dialysis session was evaluated on this biological parameter in different studies which together do not find Impact hemodialysis session on the value of troponin Achieving dosages rate hypersensitive serum troponin T in a dialysis population, will: to determine the evolution of TnT in time and what are the characteristics of the patients for whom this rate varies to know what its evolution during the session, to identify if possible the criteria that are responsible for the variation in the direction of increasing and / or its reduction and to characterize patients whose base rate is higher than the 99 percentile in the absence of clinical symptoms which could lead to establish reference population for this specific normal values. The Purpose of this study is to evaluate the serum troponin T in a hypersensitive dialysis population and verify what is the influence of the hemodialysis session, the session parameters and intradialytic events on changes in serum troponin T hypersensitive after a hemodialysis session.

Sensitive skin is a common problem, with 50% of women and 30% of men in Europe feel they have sensitive skin. The Quantitative sensory testing (QST) is a physico-psychic method that uses gradients stimuli of different modalities to measure a subjective somatosensory response. This allows to characterize sensory dysfunction by assessing the participation of small and large nerve fibers. The aim of this project is to characterize the presence or absence of a neurological disorder in patients with sensitive skin. This discovery would be a decisive argument to reinforce the suspicion that sensitive skins is linked to a small fiber neuropathy.

Teicoplanin is an antibiotic used very commonly to prevent infection during surgery. Its use has expanded rapidly in the last few years, with around 18,500 doses administered in Leeds Teaching Hospitals NHS Trust alone, in 2014-15. Unfortunately, anaphylaxis (a severe allergic reaction) to the drug appears to be increasing. These reactions can result in admission to intensive care, prolong hospital stay, or even be fatal. It is vital that patients who suffer anaphylaxis have tests to accurately identify the cause, so they can avoid the drug in future. However these tests are currently very limited, because we don't have any diagnostic tools proven to confirm or refute a diagnosis of teicoplanin allergy. We have to make a 'best guess' diagnosis, leaving patients vulnerable to harm in the future, should they require antibiotics again. We need to reliably diagnose teicoplanin allergy to reduce this arm. Where a diagnosis of teicoplanin allergy is confirmed, patients and their doctors know to avoid it. Importantly, where allergy is excluded, teicoplanin can be safely used, avoiding alternatives that may be less effective, more toxic, and more expensive. This directly benefits individuals, saves the NHS money by reducing avoidable harm, and helps improve antibiotic stewardship at a population level - which in the long term helps reduce antibiotic resistance. The clinical need for this work has become imperative. Collaborating with our industry partner ThermoFisher (significant expertise in this area), we aim to: Standardise the current skin testing protocols being used when testing patients with suspected teicoplanin allergy. Develop laboratory tests to support the skin tests, and give a more confident diagnosis to patients. Understand how and why people develop allergy to teicoplanin, to better predict and modify the allergic response.

The recent finding that early introduction of peanut can prevent ~70-90% of peanut allergy is a major step towards prevention of food allergy. However, because that finding was from a clinical trial in a very select population, there are several major questions that must be answered in order to implement these findings into clinical practice without causing more harm than good. These questions include who, if anyone, should be screened prior to early introduction for peanut allergy, how this screening should be done, and what quantity of peanut ingestion is needed to prevent peanut allergy. The goal of this project is to answer these critical questions so that the potential of these recent findings can be realized. To that end, 400 infants at high-risk of peanut allergy will be enrolled. These infants will be given a peanut skin prick test, peanut food challenge and have blood drawn for measurement of peanut IgE, and then will be followed for assessment of peanut consumption and development of peanut allergy until 3 years of age.

The purpose of this study is to investigate the differences in the quality of life of patients and caregivers who are treated by general pediatricians versus pediatric dermatologists for eczema (atopic dermatitis or AD).

The main goal of this project is to investigate how low intensity cycling exercise (1.5W/kg, for 6 minutes) influences cerebral functions, such as: Cerebral blood flow, oxygenation, and other physiological variables in different normobaric and hypobaric hypoxic conditions.

The Nutrition Study of the GA2LEN Follow-Survey was designed to investigate the association between usual dietary intake and allergic and respiratory outcomes in adults across Europe. Within this framework, a food frequency questionnaire (FFQ) was designed to ascertain usual dietary intake of 250 food items, which was translated into the languages of the participant centres. Information on daily intake of foods, nutrients, and flavonoids was derived.
