The prevalence of aspergillus skin hypersensitivity (AH) has been well studied in patients of bronchial asthma. However not many studies have evaluated the rate of AH in patients of COPD. The aim of this study is to assess rate of AH to common aspergillus antigens in patients of COPD normal healthy volunteers. The study was conducted on 100 patients of COPD and 100 normal healthy volunteers. 11% of the patients COPD showed AH positivity to aspergillus fumigatus and none of the controls were positive. Whenever suspected patients of COPD should be investigated for AH and Allergic bronchopulmonary aspergillosis (ABPA).
