Research on changes of brain natriuretic peptide,uric acid and procalcitonin levels in children patients with dilated cardiomyopathy / 国际检验医学杂志

ABSTRACT

Objective To study the changes of serum brain natriuretic peptide(BNP),uric acid(UA)and procalcitonin(PCT)levels in children patients with dilated cardiomyopathy(DCM).Methods 24 children pa-tients with DCM and 24 children undergoing healthy physical examination from March 2015 to September 2016 were selected as the observation group and control group.The observation group was divided into differ-ent Ross grade groups according to the improved Ross heart failure grade scoring.The levels of serum BNP, UA and PCT in each group were detected and their correlation with the main echocardiographic indicators was analyzed.Results The levels of BNP,UA and PCT had statistical difference between the observation group and control group(P<0.05);the BNP and UA levels had statistical difference among different Ross grades (P<0.05),moreover which were increased along with the severity increase,but the PCT level had no statisti-cally significant(P> 0.05);the BNP level was positively correlated with the DCM severity(r= 0.713,P=0.000),the UA level was positively correlated with the DCM severity(r=0.489,P=0.002),while the corre-lation between the PCT level and DCM severity had no statistical significance(r=0.288,P=0.076);the BNP had obvious correlation with main echocardiographic indicators(P<0.05).Conclusion The levels of serum BNP,UA and PCT in children patients with DCM are changed significantly,in which BNP and UA may be the good markers for reflecting the disease severity and progression or prognosis.
