Relationship between Chlamydia Pneumoniae Infection and Changes of Coronary Artery in Children / 实用儿科临床杂志

Objective To explore whether chlamydia pneumoniae(CP) infection causes the coronary artery morphology change in children and their reciprocity.Methods Serum immunoglobin M(IgM) and immunoglobin G(IgG) antibody to CP were detected by enzymelinked immunosorbent assay(ELISA) in 52 hospitalized children aged 1 month to 10 years and 5 months old in respiratory ward in our hospital,serum interleukin-6(IL-6),triglyceride(TG) and peripheral blood C-reactive protein(CRP) were also determined,morphology change of coronary artery of the patients were harvested by colored doppler echocardiogram.Results In the 52 cases,21 cases were positive of IgM,28 cases were positive of IgG,3 cases were positive both IgM and IgG.Twelve cases were high of CRP,5 cases were high of IL-6,9 cases were high of TG.In the 52 patients,the different levels of IgM,IgG,IL-6,CRP and TG had not coronary artery morphology change.Conclusion CP infection in the children does not cause the coronary artery to occur morphology change.
