Active clinical trials for "Hypersensitivity"

There has been a rise in type 2 diabetes (T2D) rates in adolescents, disproportionately in girls from disadvantaged racial/ethnic groups. This group of girls also is at heightened risk for depression, and depression and T2D are linked. Depressive symptoms are a risk factor for worsening of insulin sensitivity, one if the major precursors to T2D. In preliminary studies, the investigators found that a brief cognitive-behavioral therapy group decreased depressive symptoms and prevented worsening of insulin sensitivity in adolescent girls at-risk for T2D with moderate depressive symptoms. The aims of this study are: 1) to assess the efficacy of a cognitive-behavioral therapy depression group vs. a health education control group for improving insulin sensitivity and preserving insulin secretion in racially/ethnically diverse adolescent girls at-risk for T2D with moderate depressive symptoms over a 1-year follow-up; 2) to evaluate changes in eating, physical activity, and sleep as explanatory and 3) to test changes in cortisol factors as explanatory.

This is a randomized, controlled trial designed for children who are have already developed atopic dermatitis (AD or eczema) by 12 weeks of age. The aim is to compare the effect of proactive sequential skin care, including the twice-daily use of a tri-lipid skin barrier cream (Epiceram) or moisturizer and proactive use of fluticasone propionate cream, against reactive AD therapy, to reduce the occurrence and severity of AD in early infancy and thereby prevent food allergy (FA).

Background: Atopic dermatitis (AD), also called eczema, makes skin dry, red, and itchy. People with AD are more likely to get a food allergy than people without AD. But some food allergy tests are not always accurate in people with AD. Researchers want to study if people are truly allergic to milk and/or peanuts. Objectives: To improve the ways doctors test for food allergy in people with AD. Eligibility: People ages 3 21 who have had AD; have a high total IgE level (an allergic antibody); might have a milk and/or peanut allergy; and are currently enrolled in another NIH study Design: Participants will be screened under another protocol. Participants will have a physical exam, blood tests, and medical history. Participants will breathe into a plastic device that measures lung strength. Participants may get a small plastic tube inserted in their arm. Participants who have not had an allergic reaction to food in the past 3 years will do 1 or more oral food challenge (OFCs) depending on their allergies. They will eat a little bit of the food they might be allergic to. They will be watched for a reaction. If they have one, they will know for sure they are allergic. They may keep eating bigger portions of the food until they either have a reaction or finish all the food. In some OFCs, participants will get a placebo food. OFCs will last a few hours or 2 days. Participants will repeat all tests at each OFC. Participation can last up to 12 months. ...

Current treatments for patients with drug reaction with eosinophilia and systemic symptoms (DRESS) include supportive care, steroids and cyclosporine. No randomized controlled trial (RCT) exists in comparing these treatments and all available literature comes in the form of case reports and case series. These two treatments are considered standard of care and this trial seeks only to compare outcomes of DRESS between these two therapies. No additional labs, therapies or procedures will be used apart from those that are routinely done for patients with this diagnosis. This will be a pilot study to determine efficacy of the two therapies with particular endpoints in mind so that the investigators can study the safety of these two therapies in patients with DRESS. Data suggests a potential benefit for adults with DRESS using either steroids or cyclosporine but the investigators are seeking a comparison of efficacy of these two therapies. The study population will include adults with a Registry of Severe Cutaneous Adverse Reaction (RegiSCAR) score of greater than 4 (i.e. a likely diagnosis of DRESS). The investigators will exclude patients with sepsis, active Hepatitis B or C, active tuberculosis, a documented allergy to steroids or cyclosporine, and patients with an estimated glomerular filtration rate (eGFR) < 30 (unless on dialysis in which case the participants will be included).

The purpose of this study is to compare clinical outcomes of patients with self reported nickel sensitivity undergoing primary total knee arthroplasty (TKA) with conventional, standard-of-care vs nickel-free implants. The hypothesis is that patients with a self-reported nickel sensitivity will have similar patient reported outcome scores compared to those patients without reported nickel sensitivity. Therefor the anticipation is for there to be no differences in other clinical outcome measures or functional outcome scores between the two cohorts.

The purpose of this study is to estimate the prevalence of penicillin allergy, evaluate the diagnostic value of the allergologic work-up used in the study, and the health effects of penicillin allergy.

Investigators will conduct a hybrid implementation-effectiveness trial of a trauma-adapted Comprehensive School Physical Activity Program (CSPAP) intervention. A clustered stepped wedge design will be used, with the duration of the trial being 3 years.

This is a prospective exploratory biodistribution study in patients with interstitial lung disease (ILD). The purpose of this research study is to determine where and to which degree the FAPI tracer (68Ga-FAPI-46) accumulates in normal and fibrotic lung tissues of patients with interstitial lung disease. The study will include patients with interstitial lung disease who have or will initiate a new ILD medication OR will undergo tissue biopsy or surgery of the lung. The study will include 30 patients, the upper limit for PET imaging studies conducted under the Radioactive Drug Research Committee (RDRC) purview. Participants will be injected with up to 7 mCi of 68-GaFAPi and will undergo one PET/CT scan and one High Resolution CT of the lungs. The study is sponsored by Ahmanson Translational Theranostic Division at UCLA.

The goal of this randomized, double-blind, parallel group interventional study is to evaluate the effect of ketone bodies on healthy older adults (65-85 y) during 5 days of bed rest. The main questions it aims to answer are: Does supplementation of ketone bodies prevent the typical decline in muscle protein synthesis, muscle size, muscle function, insulin sensitivity, and muscle mitochondrial function that occurs in response to bed rest? Researchers will compare ketone supplements (KET) to an energy matched control beverage (carbohydrates and fats) to see if the ketones can rescue the decline in muscle protein synthesis rates, muscle loss, muscle function, insulin sensitivity, and mitochondrial function due to 5 days of bed rest. This may positively impact the heath of older adults subjected to bed rest.

This study aims to determine the frequency of allergy to beef meat in children with allergy to cow's milk by serum measurement. Also, the study aims to assess the sensitivity and specificity of beef IgE in relation to gold standardized of elimination challenge test and to assess effect of eating of cooked meat on symptoms of allergy in those proven to have either CMA alone +/- beef allergy (by serology).
