The disease was found to be more common among males. Poor control of asthma, constitutional symptoms, mucopurulent expectoration, increased dyspnoea and wheezing and rhonchi were the main presenting features. Skin reactivity against aspergillin was seen in 73 (82%), precipitating antibodies against Aspergillus species were positive in 64 (72%) and …
