Mycobacterium avium intracellulare infection complicated by allergic bronchopulmonary aspergillosis in a non-asthmatic patient.

Allergic bronchopulmonary aspergillosis (ABPA) most often develops in patients with asthma or cystic fibrosis. We present a 91-year-old non-asthmatic patient with pre-existing Mycobacteriumavium complex (MAC) infection who got diagnosed with ABPA. Treatment of the two conditions can be challenging as immunosuppression with steroids for treatment of ABPA may exacerbate the underlying MAC infection. Treatment with steroids and antibiotics resulted in significant improvement in the patient's condition. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.
