Population prevalence of aspergillus sensitization and allergic bronchopulmonary aspergillosis in COPD subjects in North India.
Background: Sensitization to Aspergillus fumigatus (AS) has been recently described in chronic obstructive pulmonary disease (COPD) patients. However, there is no data on the community prevalence of AS in COPD.
Objectives: To assess the prevalence of AS among COPD subjects. The secondary objectives were to (1) assess the prevalence of allergic bronchopulmonary aspergillosis (ABPA) in COPD and (2) compare the lung function in COPD subjects with and without AS.
Methods: We conducted a cross-sectional study in rural (29 villages) and urban (20 wards) communities in North India. We identified individuals with respiratory symptoms (IRS) through a house-to-house survey using a modified IUATLD questionnaire. We then diagnosed COPD through specialist assessment and spirometry using the GOLD criteria. We assayed A.fumigatus-specific IgE in COPD subjects. In those with A. fumigatus-specific IgE ≥0.35 kUA/L (AS), ABPA was diagnosed with raised serum total IgE and raised A.fumigatus-specific IgG or blood eosinophil count.
Results: We found 1315 (8.2%) IRS among 16,071 participants >40 years and diagnosed COPD in 355 (2.2%) subjects. 291 (82.0%) were men and 259 (73.0%) resided in rural areas. The prevalence of AS and ABPA was 17.7% (95% CI, 13.9-21.8) and 6.6% (95% CI, 4.4-8.8). We found a lower percentage predicted FEV1 in COPD subjects with AS than those without (p =.042).
Conclusions: We found an 18% community prevalence of AS in COPD subjects in a specific area in North India. Studies from different geographical areas are required to confirm our findings. The impact of AS and ABPA on COPD requires further research.
期刊介绍：
The journal Mycoses provides an international forum for original papers in English on the pathogenesis, diagnosis, therapy, prophylaxis, and epidemiology of fungal infectious diseases in humans as well as on the biology of pathogenic fungi.
Medical mycology as part of medical microbiology is advancing rapidly. Effective therapeutic strategies are already available in chemotherapy and are being further developed. Their application requires reliable laboratory diagnostic techniques, which, in turn, result from mycological basic research. Opportunistic mycoses vary greatly in their clinical and pathological symptoms, because the underlying disease of a patient at risk decisively determines their symptomatology and progress. The journal Mycoses is therefore of interest to scientists in fundamental mycological research, mycological laboratory diagnosticians and clinicians interested in fungal infections.
