ABSTRACT
Background: Fungal colonisation of airways in Post TB patients, can lead to a spectrum of diseases based on the immune response of the host. This study was aimed at studying the different entities of this spectrum. Methods: A cross sectional observational study was conducted over 100 patients of post TB patients to make an observation of the diseases of the spectrum of Aspergillus infections. Results: Of the 100 patients who were studied, IPA was found in 24 (48%), ABPA in 13 (26%), CPA in 5 (10%) patients out of the 50 diabetics. ABPA in 23 (46%) patients, Simple colonization, CPA in 11 (22%) and 4 (8%) patients showed IPA out of the 50 non-diabetics. Conclusion: Chronic pulmonary Aspergillosis was the most common disease from Aspergillus among Post TB patients. Diabetes was associated with invasive forms of Aspergillosis, Invasive Pulmonary Aspergillosis (IPA) and subacute invasive pulmonary aspergillosis (SAIA).
