Peanut Oral Immunotherapy in Children: IMPACT Follow Up Study
This application is being submitted as a follow-up to Protocol "Oral Immunotherapy for Induction of Tolerance in Peanut Allergic Children-The IMPACT Study." The IMPACT study was a double-blind, placebo-controlled study of peanut oral immunotherapy in children 12-48 months of age. As part this protocol, all participants who received placebo treatment were promised the opportunity to receive open label treatment at the conclusion of the double-blind phase and initial follow-up. At the time of submitting that protocol, the investigator did not specify any detailed protocol for the open label crossover treatment, as this is an evolving field,...
Peanut Oral Immunotherapy Study of Early Intervention for Desensitization
The purpose of this study is to determine the efficacy and safety of AR101 in peanut‑allergic children aged 1 to < 4 years.
Peanut Reactivity Reduced by Oral Tolerance in an Anti-IgE Clinical Trial
The investigators will perform a double blind, placebo controlled clinical trial with Xolair (omalizumab) at four centers to safely and rapidly desensitize patients with severe peanut allergy. The investigators will determine if pretreatment with anti-IgE mAb (Xolair/omalizumab) can greatly reduce allergic reactions and allow for faster and safer desensitization.
PIFR-based Inhalation Therapy in Patients Recovering From AECOPD
This study is designed to determine whether the optimized inhalation therapy based on peak inspiratory flow rates (PIFR) measured against the simulated resistance can reduce the rate of treatment failure in patients recovering from acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Errors in inhaler use and quality of life are also to be evaluated. The study will recruit 460 patients with AECOPD whose exacerbated symptoms are relieved by 5-7 days of standard therapy. The participants are divided into PIFR group and control group in a 1:1 ratio according to a random number table method. All the patients will be given ...
Pilot Study of Esocheck in Eosinophilic Esophagitis
Eosinophilic esophagitis (EoE) is a prevalent chronic inflammatory condition of the esophagus characterized by esophageal eosinophilia that can lead to inflammation and stricture formation. To assess remission, esophagogastroduodenoscopies (EGD) with biopsies are performed. This can lead to multiple EGDs, which are invasive and costly procedures. EsoCheck is a promising noninvasive device. It is an encapsulated balloon that can be easily swallowed and collect cells from the distal esophagus. The primary aim of this study is to determine the feasibility and safety of EsoCheck compared with standard endoscopy and biopsies in the assessment of...
Pilot Study on Traditional Chinese Medicine and Food Allergy
Recently, there has been an increasing interest in using traditional Chinese medicine for food allergy. The Harvard group has successfully demonstrated the Food Allergy Herbal Formula - FAHF2 completely blocked peanut-induced anaphylaxis in a murine model, and currently being studied in human. Therefore, in collaboration with the Institute of Chinese Medicine, CUHK, the investigators have developed a more simplified Chinese herbal formula - X (CHFX), containing four food-grade Chinese herbs, Wu-mei (Fructus Pruni Mume); Ling-zhi (Gonoderma); Huang-bai (Cortex Phellodendron) and Zhi-su (Perilla frutescens). In the present study, the...
Post-marketing Safety Surveillance of Xueshuantong-Injection : a Registry Study
This registry aims to monitor the safety of Xueshuantong Injection and to identify the potential risk factors for the adverse drug reactions.
Predictors of Persistent Peanut Allergy at Age 5 Years
The purpose of this study is to determine if avoidance of peanut by children with positive allergy testing to peanut in the first 5 years of life increases the likelihood of developing a persistent peanut allergy by age 5 years. To answer this question, the investigators need to determine which children with positive allergy testing to peanut have reactions after eating peanut (allergic to peanut) and which are able to tolerate eating peanut (not allergic). The investigators plan to conduct double-blind placebo-controlled peanut challenges (gold standard for peanut allergy diagnosis) for CHILD study (http://www.canadianchildstudy.ca) ...
Prescreening Protocol to Enroll in Food Allergy Clinical Studies at a Single Site
This is a protocol for prescreening of participants who would like to be in clinical studies in our Center at Stanford.
Preventing Atopic Dermatitis and ALLergies in Children
The primary objective is of the PreventADALL study is to test if primary prevention of allergic diseases is possible by simple and low cost strategies, and secondary to asses the impact of xenobiotic exposure and microbiota in and on the body and the environment on allergic disease development. The secondary objective is an exploratory focus to investigate early life risk factors for development of non-communicable diseases, including asthma and allergic diseases as well as for diseases that may share common risk factors, including cardiovascular disease, obesity and diabetes. Design: A multi-national population-based prospective...
