An animal model of allergic asthma through the challenge of Pleurotus sapidus besidiospores in primed rats was developed for investigating the role of cytokines in the pathogenesis of the disease. In the study a series of related cytokines and their receptors, including their activity and mRNA levels of spleen lymphocytes isolated from asthmatic rats, were measured. Determined by 3H-TdR incorporation assay and NAG microcolorimetric assay, Con A-induced spleen lymphocyte proliferation and IL-2 activity in culture supernatants of spleen lymphocytes from 7-day challengedrats with allergic asthma increased significantly by 261% and 208%, respectively, as compared with those in the control. Cytokines and their receptor expression at mRNA levels were determined by RNA/cDNA hybridization, using (α-32P-dCTP radiolabeled cDNA probes for different cytokines and their receptors in vitro. The results showed that mRNA expression of IL-4, GM-CSF, IL-6, IL-2 and IL-2R, except IL-6R, in lymphocytes of 7-day-challenged asthma-suffering rats, increased significantly by 54%, 45%, 170%, 83% and 76%, respectively. In 2-day challenged-rats, mRNA levels of IL-4, IL-6 and IL-2 increased by 37%,58% and 125%, respectively, whereas mRNA leve1s of GM-CSF, IL-2R and IL-6R remained unchanged. Thus, the experimental results suggested a significant increase in TH2type cytokines in the pathogenesis of Pleurotus sapidus besidiospore-induced allergic asthma and IL-4 may play an essential role.展开更多

By using case-control method, DNA and clinical data were obtained from allergic asthmatic patients and compared with those in the control subjects. The subjects were genotyped for the IL-4 C-589T promoter polymorphism, the IL-4Rα chain Q576R and the AICDA C8408T by poly-merase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The results showed that the IL-4 C-589T was not associated with adult allergic asthma in China. However, the IL-4Rα chain 576R/R and AICDA 8408T/T frequency was significantly increased in allergic asthma group as compared with that in the control group [odd ratio (OR) = 3. 797 and 9. 127, respectively; P<0. 01)] and was correlated with the increased plasma total IgE. These data suggested that the IL-4Rα chain 576R/R and AICDA 8408T/T genotypes confer genetic susceptibility to adult allergic asthma in China.展开更多

The patient is a man born in 1948, who first presented with rhinorrhea, nasal congestion and chronic urticaria, and had an episode of asthma after ingestion of non-steroidal anti-inflammatory drugs （NSAIDs） for the further eight years. He was diagnosed as AIA and the symptoms decreased in frequency when avoiding NSAIDs. At the age of 45, he presented with unusual symptoms, such as malaise, fever, and coughing. The diagnosis of ABPA was made based on his clinical features, such as the symptoms of asthma, typical pulmonary imaging, positive skin test, and high levels of the total IgE （T-IgE） and sIgE. Itraconazole accompanied with oral prednisone prevented pulmonary disease from developing.展开更多
