Multicenter Airway Research Collaboration

Overview

Multicenter Airway Research Collaboration (MARC) is an international research network focusing on respiratory/allergy emergencies such as asthma, COPD, anaphylaxis, bronchiolitis, and other similar disorders.

Two major research activities are MARC-35 and MARC-43, which are two multicenter cohorts on infants. The cohorts examine which children develop recurrent wheezing and asthma, and the relation of airway microbiome to risk of childhood asthma.

Past Initiatives

The 38th Multicenter Airway Research Collaboration (MARC-38) was a multicenter chart review study that investigated the characteristics, ED management, and post-ED care of 2,000 children and adults who presented to the ED with an acute allergic reaction to food or insect stings. Please contact Dr. Carlos Camargo if you would like additional details.
