Snapshot A 24-year-old woman with a past medical history of atopic dermatitis presents to an urgent care center for dyspnea on exertion. She reports that for the past few months, she has become increasingly short of breath with exertion, particularly during exercise. She denies any other symptoms and denies having ever smoked or been exposed chronically to second-hand smoke. Close examination into her pediatric records shows a documented history of hepatomegaly but no workup. Labs reveal significantly decreased alpha-1 antitrypsin and increased transaminitis. She is given nebulized ipratropium and albuterol, a course of steroids, and referred for regular treatments with alpha-1 antitrypsin.
