Active clinical trials for "Hypersensitivity"

This trial is performed to assess whether the Grazax-R treatment is safe to use in children aged 5-12 years.

This study will determine whether use of an in-home test kit results in decreased dust mite allergen levels in homes of children who are sensitive or allergic to dust mites. Dust mite allergens come from dust mites - microscopic spider-like animals that feed on house dust. Dust mites are common anywhere there is dust, such as in carpeting and beds. Some people are allergic to dust mite allergens and may develop asthma from living near them. People who live in the Research Triangle Park area of North Carolina who have a child between 5 and 15 years old with a dust mite allergy or sensitivity may be eligible for this study. Participants must plan to remain in the same house for at least 12 months from the start of the study. At least half the floor of the child's room must be carpeted. Participants are given materials on how to reduce dust mite allergens in their home. Study staff visit participants' homes three times over a 12-month period to ask questions about the home, home cleaning habits, and participants' experiences with home test kits (see below) for measuring dust mite allergen. At each visit, staff collect dust samples from the child's bedroom, the parents' bedroom, and the living room. The dust samples are analyzed in the laboratory for dust mite allergens and the results are given to the participants at the end of the study. Participants are also given four home test kits for measuring dust mite allergen in the home. At the first home visit, staff instruct the participants on how to use the kits and answer any questions they may have. The kits are mailed at certain times during the study for the participants to use to measure allergen and send the results to the study investigators in a pre-paid addressed envelope. A control group is given educational materials but no test kits.

This trial is performed to assess whether the Grazax® treatment compliance can be improved by use of a compliance device (Memozax®).

The goal of this proposal is to culturally adapt and tailor an existing, theory-based intervention, using state-of-the-art methods designed to maximize cultural sensitivity, feasibility and acceptability to HIV+ Latino MSM, and to test it in a small randomized controlled trial (n=60 intervention; n=60 control).

This study will critically evaluate the effects of a novel dietary fiber administered to subjects at high risk for developing diabetes to determine if this intervention will improve insulin sensitivity compared to control product administration and, thus, decrease risk for developing diabetes. The hypothesis is that consuming this novel fiber twice a day for 12 weeks will significantly decrease fasting plasma glucose, insulin and glycosylated hemoglobin values in pre-diabetic subjects (i.e. subjects with fasting plasma glucose levels 95-140 mg/dl at screening) compared to consumption of the control product.

The aim of this study is to evaluate the acceptability, feasibility and preliminary effects a GP_Posit intervention. GP_Posit is an intervention where mothers will learn how to participated in their preterm infant's care and positioning while being guided by a nurse. Preliminary effects will be estimated on maternal sensitivity, stress and anxiety as well as preterm infant's neurodevelopment.

People who are undergoing oral immunotherapy for food allergy treatment can feel anxious about the treatment process, particularly when they have allergic responses (e.g., hives, vomiting, nausea) during the dosing process. People may commonly believe that these symptoms are simply side effects that must be endured or avoided. However, the investigators propose that changing participants' mindsets about the meaning of symptoms-toward viewing them as a sign that the treatment is working and desensitization is increasing-during the treatment process will reduce anxiety and improve treatment outcomes.

The purpose of this study is to evaluate use of a mobile application (also commonly referred to as an app) designed to support caregivers of children with newly diagnosed food allergy. This study has 2 phases. In Phase 1, the researchers obtained feedback regarding use of mobile apps from caregivers who have been managing their child's food allergy for one year or more. The researchers then used this feedback to build a mobile app for caregivers of children with newly diagnosed food allergy. In Phase 2, the researchers will evaluate the mobile app during a 4-week evaluation period with a group of caregivers of children newly diagnosed with food allergy. The data obtained from this study will hopefully benefit caregivers of children with newly diagnosed food allergy.

In this research project, the effect of different polyphenol-containing beverages with varying alcohol content of < 0.4 vol% on immune function as well as muscular growth factors will be investigated

Adverse drug reactions are an important public health consern that affects physician prescriptions and practice. The responsibilities of healthcare professionals in monitoring, prevention, treatment and reporting of drug hypersensitivity reactions and drug allergies are essential for patient safety. Providing drug safety must be one of the main goals to be achieved for every member of our society. In our study, we planned to evaluate the knowledge, attitudes, and behaviors of healthcare workers in our country about drug hypersensitivity reactions in pediatric patients and to determine the risk factors that may affect them.
