Immunological Response After Shrimp Oral Immunotherapy Treatment

Study Purpose

Oral immunotherapy is effective in desensitized food allergy. Shrimp allergy is increasing in Thailand. So the purpose of our study is to determine level of specific immunoglobulin E antibodies to shrimp, Immunoglobulin G4 and immunoblot analysis in shrimp allergy patients after shrimp oral immunotherapy.

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Allergy to Shrimp, Immunotherapy
Additional Details

All subject in this study were sensitized to shrimp. All patient was clinically evaluated, with focus on shrimp allergy by medical history, medical examination and gold standard oral food challenge test. Compare oral immunotherapy to shrimp and shrimp avoidance. Blood sample was taken for baseline determination of immunoglobulin E antibodies to shrimp. The primary outcome was the specific immunoglobulin E antibodies to shrimp,Immunoglobulin G4 and immunoblot analysis in case that oral immunotherapy.
