Genomic Study of Genetic Polymorphisms Involved in Immediate Allergic Reactions to Beta-lactam Antibiotics

PANGENOMIC-BL
Start date: June 2012
Phase: N/A
Study type: Observational

Beta-lactam antibiotics include penicillin and cephalosporins and are among the most prescribed antibiotics. This category of drugs is the most involved in immediate allergic manifestations with 2% reactions in treated subjects and a fatal outcome in 1/50000 treatments. Reactions are IgE-mediated and have a considerable but unknown genetic origin, revealed by studies in groups of different ethnical origins in the same geographical region. There are also some families with a high frequency of allergic reactions without identified Mendelian inheritance. The purpose of this study is to identify predictive risk factors associated to immediate allergic reactions against beta-lactam antibiotics with a pangenomic approach. A secondary purpose is to identify rare predictive factors with homozygosity mapping and exome sequencing in various families with high risk of allergy to beta-lactam antibiotics.
