Abstract

A 73-year-old woman suffering from dyspnea on effort and chronic cough was admitted to our hospital. Chest computed tomography disclosed ground-glass opacities, irregular linear opacities and honeycombing distributed predominantly in the subpleural area. The serum levels of SP-D and KL-6 rose to 889 ng/ml, 1,755 U/ml, respectively. These findings indicated idiopathic pulmonary fibrosis. However, the number of lymphocytes and the CD4/CD8 ratio in the BAL fluid were elevated. Transbronchial lung biopsy specimens demonstrated alveolitis with granuloma formation. The evidence that she had lived in a house with a heavy fungal growth and that tests of precipitation in response to Penicillium corylophilum were positive confirmations of a diagnosis of chronic hypersensitivity pneumonia.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
