Filter by:Skin prick test (SPT) was used for diagnostic test for type 1 hypersensitivity. The efficacy and safety of SPT were proved. The positive control of SPT is histamine. In Thailand, the most common concentration of histamine for SPT is 10 mg/ml. However, in some practice they use other concentration (1, 2.5 mg/ml). This study will find the proper concentration of histamine for positive control use in SPT.
The prevalence of Allergic rhinitis(AR) and asthma was increased world wide. In 1998, ISAAC found that prevalence of AR and asthma inThailand was in moderately high group. Tests for immediated reaction SPT and spIgE, were used for evaluated sensitization of allergen in patient. They guided the investigators for proper management as well as patient education. Clinician will use the result for choose allergen in case that might need immunotherapy. SPT is safe and more economic for patient. Specific IgE has an advantage in patient who cannot withhold antihistamine prior SPT. In United state had a trial of result between SPT and spIgE for cockroach, cat, house dust mite and mold. It showed the correlation between two tests. In Thailand, the investigators haven't had data about it yet.
Insulin allergy (IA) is still observed even with recombinant human insulin and insulin analogs. Obviously, the usual attitude facing an allergy, i. e. exclusion of the allergen, poses problems in face of IA because insulin is often vital for the patient. IA is thus a complex situation in which a rigorous diagnostic procedure to identify the exact allergen is necessary to propose a therapeutic answer; the purpose of the study is 1/ to validate a diagnostic algorithm for patients presenting with possible allergy. 2/ to investigate immunogenetic profiles of patient with insulin allergy 3/ cellular mechanisms of IA.
The purpose of this study is to explore the safety and efficacy of a sublingual (under the tongue) immunotherapy (SLIT) dosing regimen and an oral immunotherapy (OIT) regimen in inducing desensitization and long term tolerance in children with persistent peanut allergy.
The purpose of this study is to evaluate the safety and side effects of a study product that contains recombinant modified peanut proteins (EMP-123) in healthy and peanut-allergic participants. This is a first in human study. As of November 2009, this study is no longer recruiting healthy volunteers and will only be recruiting individuals with peanut allergies.
The purpose of this study is to evaluate the safety and immune response to daily sublingual (under the tongue) immunotherapy (SLIT) with peanut extract in adults and children with peanut allergies.
The purpose of this study is to determine if oral immunotherapy (OIT) will desensitize a child with an allergy to egg and eventually lead to the development of tolerance to egg.
