Allergic bronchopulmonary aspergillosis in India

Allergic bronchopulmonary aspergillosis (ABPA) is a lung disorder caused by immune-mediated reactions mounted against Aspergillus fumigatus. The disorder most commonly complicates the course of patients with asthma and cystic fibrosis. From its first description in 1952, significant advances have been made in understanding the pathogenesis and the diagnosis and treatment of ABPA. In the last two decades, most research on ABPA has been published from India. The prevalence and clinical presentation may differ in India from that reported elsewhere. Herein, we review the epidemiology, clinical and radiological characteristics, and distinctive features of ABPA in the Indian subcontinent. To support the review, we surveyed pulmonologists nationwide to understand the challenges in diagnosing and managing ABPA. The survey has yielded valuable insights into the practices associated with the diagnosis and management of ABPA in India.
