The relationship of bronchial provocation tests and the onset of the disease / 中国综合临床

ABSTRACT

Objective To investigate the correlation between bronchial provocation tests and the onset of the disease.Methods One hundred and seven patients who hospitalized in General Hospital of China Aviation from 2013-2014 were selected as our subjects.They all were with unexplained symptoms such as cough and asthma suppress.All the patients were performed bronchial provocation tests.In accordance with the onset time,patients were divided into acute (＜ 3 weeks),subacute (3-8 weeks) and chronic (＞ 8 weeks) groups.The positive rates of bronchial provocation test of three groups were compared.Results Of all 107 patients,36 patients were positive and 71 were negative in terms of bronchial provocation test.The cases with acute,subacute and chronic disease history were 16,36 and 55 respectively.The positive rate of bronchial provocation tests in different onset were 56.3％ (9/16),36.1％ (13/36),23.6％ (13/55) respectively,and there was statistics significant difference(x2 =6.275,P ＜ 0.05).The positive rate of bronchial provocation tests in acute group was higher than that in chronic group (x2 =6.165,P ＜ 0.05).There was positive correlation between the positive rate of bronchial provocation tests and the onset,and the correlation coefficient Pearson was 0.239 (P ＜0.05).Conclusion There is a correlation between the positive rate of bronchial provocation tests and the onset.We should strengthen the monitoring in patients with acute onset and follow-up.
