Pediatric bronchial hyperresponsiveness and asthma phenotypes

Dr. Lee and colleagues have examined the intersection of 2 relevant aspects of asthma, bronchial hyperresponsiveness (BHR) and clinical patterns of childhood asthma.1 Using the novel approach of considering different patterns of BHR as characteristic phenotypes, Dr. Lee demonstrated a relationship between the BHR phenotypes and the clinical patterns of asthma in children. These investigators had previously demonstrated a relationship between atopic phenotypes and the development of BHR and asthma.
