ABSTRACT
Objective To determine the levels of soluble intercellular adhesion molecule-1(SICAM-1) in serum and induced sputum in children with mycoplasma pneumoniae pneumonia(MPP),and to investigate the role of SICAM-1 in pathogenesis of MPP.Methods The levels of SICAM-1 in serum and induced sputum and sputum cell count were measured by enzyme linked immunosorbent assay(ELISA) kit in 44/34 children with MPP in acute episode period,36/28 children in remission episode period and 38/30 healthy children.Results The levels of serum SICAM-1,sputum SICAM-1 and percent of neutrophil(N),lymphocyte(L),eosinophile(EO),mast cell(Ma) were significantly higher in acute episode period in MPP than those in remission episode period and control group,respectively((all P0.05);)the indexs in remission period and in controls showed no marked difference.The le-(vels of) serum and sputum(SICAM-1) in children with asthma attack in acute and remission episode periods in MPP increased significantly compared with those in children without asthma in both periods(P
ABSTRACT
Objective To compare the heart function and observe the clinical prognosis of dilated cardiomyopathy(DCM) in children treated with combination of prednisone and azathioprine and high dose intravenous immunoglobulin(IVIG).Methods From Jan.1998 to May 2004,20 children who met the diagnostic criteria of DCM were divided into 2 therapeutic groups(groupⅠ,groupⅡ) according to the time of hospitalization.On the basis of traditional congestive heart failure(CHF) therapy,the children in groupⅠwere treated with immunosuppressive therapy(prednisone plus azathioprine) and the children in groupⅡ were treated with high dose IVIG.The course of treatment was 6 months for all children.Heart functions in all children were evaluated and echocardiographic parameters including left auricular diameter(LA),left ventricular end diastolic diameter(LV),left ventricular ejection fraction(LVEF) and cardiac index(CI) were measured before and after therapy,respectively.All children were followed up for 1 year to observe survival rate(%).The findings were analyzed by t test and ?~2 test.Results The percentage of heart function increased from Ⅲ-Ⅳ toⅠ-Ⅱin groupⅠ,which was lower than that in groupⅡ(P
