P58 - The role of osteopontin and vitamin D in school-age asthmatic children for predicting asthma exacerbation

Results OPN levels (ng/ml) were significantly higher in asthmatics in exacerbation period when compared to nonexacerbation period, and controls [30,61±3,21 vs. 28,7 ±3,71 vs. 27,62±3,91, respectively; p<.001]. There was no significant difference among OPN levels between asthmatics and controls, (p=.094). 25(OH)D levels (ng/ml) were significantly lower in asthmatics in exacerbation period when compared to non-exacerbation period, and controls [30,15±5,11 vs. 32,23±5,80 vs. 34,16±5,86, respectively; p<.001]. There was no significant difference among 25(OH)D levels between asthmatics and controls, (p=.051).There was a correlation for both OPN and 25 (OH)D levels among asthmatics in exacerbation period and non-exacerbation period, respectively (r=0,40, p<,001 and r=0,62, p<.001). But, no correlation between OPN and 25(OH)D levels among asthmatics in exacerbation and non-exacerbation periods (r=-0,78, p=,481; r=0,10, p=,448, respectively).
