[The evaluation of atrial natriuretic peptide and endothelin in serum of the patients with non-atopic bronchial asthma during exacerbation].
The aim of the study was to evaluate concentrations of atrial natriuretic peptide (ANP) and endothelin in blood serum of the patients with nonatopic bronchial asthma in the exacerbation phase and during non-symptomatic period. The study included 20 patients with nonatopic bronchial asthma (10 women and 10 men, mean age 34.2) treated in the Allergological Outpatient Clinic in Zabrze (Poland). A control group consisted of 5 healthy volunteers without atopy. The study consisted of evaluation of the ANP and endothelin in blood serum by radioimmunoassay and by functional respiratory tests. It was shown that ANP concentrations during bronchial asthma exacerbation were two times lower than in the same group examined in the remission phase (7.8-13.7 pmol/ml, p < 0.05). At the time of bronchospastic symptoms occurrence, the concentrations of endothelin were statistically significant and higher than in the non-symptomatic group (11.6-6.9 pmol/ml, p < 0.05). In the examined group the reverse proportion relation between concentrations of the studied peptides in blood serum was observed r = -0.56, p < 0.05 according to Spearman test.
