Change and clinical value of SP-D,CCL18 and CC16 in serum and in exhaled breath condensate in acute exacerbation of COPD / 重庆医学

ABSTRACT

Objective To study the change and clinical value of SP‐D ,CCL18 and CC16 in serum and in exhaled breath con‐densate in acute exacerbation of chronic obstructive pulmonary disease .Methods Sixty two cases of COPD patients admitted in our hospital from 2010 January to 2013 December were selected as the research object .All the 62 patients were divided into group A(32 patients with COPD in acute exacerbation) and group B(30 patients with COPD in remission stage) in accordance with the severity of COPD .Thirty six cases of health people were selected as the control group .Statistical subjects SP‐D ,CCL18 ,CC16 content in se‐rum and in exhaled breath condensate ,and the relations between the various indexes and age ,smoking ,pulmonary function and BMI were analyzed .Results The exhaled breath condensate SP‐D ,CCL18 content in group A was significantly higher than that of B group and the control group (P<0 .05) ,and the SP‐D ,CCL18 in group B was higher than that in control group (P<0 .05) .The se‐rum SP‐D ,CCL18 ,CC16 content in group A was significantly higher than that of B group and the control group (P<0 .05) ,and the SP‐D ,CCL18 ,CC16 in group B was higher than that in control group (P< 0 .05) .Serum SP‐D ,CCL18 levels were significantly higher than those in the exhaled breath condensate (P< 0 .01) .Exhaled breath condensate SP‐D was positively associated with smoking age (r=0 .298 ,P<0 .05) ,and FEV1% pred ,FEV1/FVC (% ) showed a negative correlation (r= -0 .318 ,-0 .402 ,P<0 .05);the serum levels of SP‐D was positively associated with tobacco (r=0 .297 ,P<0 .05) ,and FEV1% pred ,FEV1/FVC (% ) were negative correlated (r= -0 .278 ,-0 .298 ,P<0 .05);serum CC16 and FEV1% pred ,FEV1/FVC (% ) were negatively corre‐lated (r= -0 .358 ,-0 .382 ,P<0 .05);Exhale breath condensate SP‐D ,condensate CCL18 ,SP‐D ,CCL18 serum ,serum CC16 were are positively correlated in each two (P<0 .05);and there was no significant correlation between other indexes and age ,smoking , pulmonary function and BMI etc .Conclusion Exhaled breath condensate ,serum SP‐D ,serum CCL18 ,exhaled breath condensate , exhaled breath condensate ,serum CC16 are closely related to acute exacerbation of COPD ,and monitoring the indicators can be judgment of the degree and prognosis of COPD .
