Clinical, spirometric, serological differences and outcomes in patients with allergic bronchopulmonary aspergillosis (ABPA) based on the classification by Kumar et al with and without the presence high attenuation mucus (HAM).

Values are expressed as mean (SD) or median (IQR) unless otherwise stated; ABPA-S - serologic ABPA; ABPA-CB - ABPA with central bronchiectasis; ABPA-CB-ORF - ABPA with CB and other radiologic findings;aABPA-CB-ORF value significant compared to ABPA-s;bABPA-CB-ORF value significant compared to ABPA-CB;cABPA-CB value significant compared to ABPA-s;dABPA-CB value significant compared to ABPA-CB-ORF;The A fumigatus specific IgE levels and eosinophil counts, but not the total IgE levels are different between the groups (columns 1 to 3). On post hoc analysis, the A fumigatus specific IgE levels are higher in ABPA-CB (column 2) compared to ABPA-S (column 1) and the eosinophil counts are higher in ABPA-CB (column 2) in comparison to the other two groups (columns 1 and 3). Once HAM is excluded (columns 5 and 6), only the eosinophil counts remain significant in ABPA-CB (column 5) compared to ABPA-S (column 1) and ABPA-CB-ORF (column 6).
