Daniel A. Salerno, MD, MS, Professor of Clinical Thoracic Medicine and Surgery at the Lewis Katz School of Medicine at Temple University, provided perspective for a Medscape article on new findings on optimizing diagnostic approaches for allergic bronchopulmonary aspergillosis (ABPA). The findings were published in Allergy and Asthma Proceedings and presented at the American Academy of Allergy, Asthma & Immunology (AAAAI) 2026 Annual Meeting. Salerno, who was not involved in the study, emphasized the findings were important because they challenge traditional tools used to diagnose ABPA and reinforce the idea that allergic fungal lung disease exists along a spectrum.
