ICD-10: J67.2

Bird fancier's lung, classified under ICD-10 code J67.2, is a specific type of hypersensitivity pneumonitis. This condition arises from an allergic reaction to organic dust, particularly from bird droppings, feathers, or other organic materials associated with birds. Below is a detailed clinical description and relevant information regarding this diagnosis.

Clinical Description

Definition

Bird fancier's lung is a form of hypersensitivity pneumonitis, which is an inflammatory response in the lungs triggered by inhaling organic dust. This condition is particularly associated with individuals who frequently handle birds, such as pet bird owners or those working in avian environments.

Pathophysiology

The immune system reacts to inhaled antigens from birds, leading to an inflammatory response in the lung tissue. This can result in symptoms ranging from mild respiratory issues to severe lung damage if exposure continues over time. The condition is characterized by the presence of immune complexes and inflammatory cells in the alveoli, which can lead to pulmonary fibrosis if not addressed.

Symptoms

Common symptoms of bird fancier's lung include:
- Cough
- Shortness of breath
- Chest tightness
- Fever and chills (in acute cases)
- Fatigue

Symptoms may vary based on the duration and intensity of exposure to the offending antigens. Acute episodes can occur within hours of exposure, while chronic symptoms may develop over time with ongoing exposure.

Diagnosis

Clinical Evaluation

Diagnosis typically involves a thorough clinical history, including exposure to birds and related environments. Physicians may conduct physical examinations and order imaging studies, such as chest X-rays or CT scans, to assess lung involvement.

Laboratory Tests

• Serological Tests: Blood tests may be performed to detect specific antibodies against bird antigens.
• Pulmonary Function Tests: These tests help evaluate the extent of lung impairment.

Histopathological Examination

In some cases, a lung biopsy may be necessary to confirm the diagnosis, revealing characteristic changes associated with hypersensitivity pneumonitis.

Treatment

Avoidance

The primary treatment for bird fancier's lung is the avoidance of exposure to birds and their droppings. This is crucial to prevent further lung damage and manage symptoms effectively.

Medications

• Corticosteroids: These may be prescribed to reduce inflammation in acute cases.
