| description | Introduction: Difficult-to-control asthmatics, as defined by
the Global Initiative for Management of Asthma (GINA), belong
to a subset of patients whose symptoms remain uncontrolled
despite adhering to maximal optimised therapy. Complex
hypersensitivity reactions in response to airway colonization
with Aspergillus fumigatus, which occurs in patients with asthma
or cystic fibrosis, are established factors for a poor response to
treatment and frequent exacerbations. Only limited data related
to Allergic Bronchopulmonary Aspergillosis (ABPA) is available
from India, particularly from Kerala.
Aim: To assess the occurrence of ABPA in patients with difficultto-control asthma using the modified ISHAM criteria.
Materials and Methods: This cross-sectional analysis was
conducted in the Department of Pulmonary Medicine, Institute
of Chest Diseases, Government Medical College, Kozhikode,
Kerala, India from February 2019 to July 2020. The study
population comprised asthmatics attending the Pulmonary
Medicine Outpatient Services who were on regular medications,
including optimal doses of inhaled corticosteroid and longacting beta-agonist combinations. Patients with two or more
exacerbations per year requiring systemic steroids for symptom
control and a positive skin test for Aspergillus fumigatus antigen
were further analysed using the modified International Society
for Human and Animal Mycology (IHAM) criteria to determine
the proportion of difficult-to-control asthmatics with ABPA. A
total of 185 subjects were enrolled. Twelve patients opted out of
the study, and the remaining 173 patients were screened using
the modified ISHAM criteria. Statistical analysis was performed
using Stastistical Packages of Social Sciences (SPSS) software
version 21.0. Continuous parameters were expressed as mean
and median, while categorical parameters were measured as
frequency and percentages.
Results: It was observed that 104 (60.1%) patients belonged
to the age group between 41-60 years, while approximately 60
patients (34.7%) were below 40 years of age. Among the 173
patients, 86 (49.7%) tested positive for Aspergillus fumigatus
antigen. Applying the ISHAM criteria, it was found that only 17
(9.8%) of these patients satisfied the criteria for co-existent
ABPA. A total of 101 patients (58.4%) required at least one
hospital admission, while 4 (2.3%) patients required more than
three hospital admissions per year. Total 21 (12.1%) patients had
IgE specific to Aspergillus fumigatus, while total IgE levels were
elevated in 46 (26.6%) cases. Thirty-six cases (20.8%) had a high
peripheral eosinophil count
Conclusion: This study suggests the possibility of the treating
physician overlooking 10% of asthmatics in this region who are
being managed as difficult-to-control asthma, but who have
co-existent ABPA. This subset should be identified early in the
course and managed separately for better treatment response. |
