From Birds to Breaths: Investigating a Chronic Cough in a Bird Owner – A Case Report

The interaction between humans and birds dates back to the dawn of humanity. This connection has led to the emergence of certain diseases, one of which is hypersensitivity pneumonitis, also known as Bird Fancier's Lung. First described in 1960(1), hypersensitivity pneumonitis is an immune-mediated reaction in the lungs, often triggered by long-term exposure to birds and blood tests often reveal positive antibody results specific to bird types, such as pigeons(2). It can present in a variety of ways, ranging from no symptoms to severe pneumonia-like symptoms, including weight loss(1,3). Diagnosing this condition can be challenging, as it may resemble lung cancer, as seen in our case, which involved a patient presenting with cough, weight loss, and shortness of breath. A thorough history, including questions about pets, can raise suspicion of Bird Fancier's Lung. Treatment may involve a course of oral steroids, avoidance of exposure, or wearing protective equipment(4). In severe cases, oxygen therapy may be necessary(3) . Our case describes the patient’s journey from the initial presentation to the formal diagnosis and successful treatment, leading to the complete recovery of his symptoms. Despite the diagnosis, the patient chose to continue his bird-breeding hobby while maintaining a low-dose oral prednisolone regimen.
