ABSTRACT

Objective To investigate the clinical features of children with systemic lupus erythematosus (SLE).Methods Ninety-five patients hospitalized in Wuxi Children's Hospital from Jan.2003 to Dec.2013 were analyzed retrospectively.They were diagnosed as SLE for the first time.The clinical features of SLE between boys and girls were compared.Chi-square test was used for statistical analysis.Results Of the 95 cases with SLE,12 were boys and 83 were girls.Clinical manifestations showed 69 cases with facial rash (72.6％),43 cases with fever (45.3％),31 cases with arthritis (32.6％),24 cases with serositis (25.3％),23 cases with oralulcer (24.2％),13 cases with allergy to sunlight (13.7％),11 cases with nervous system damage (11.6％).Laboratory examination94 cases (98.9％) with anti-nuclear antibody positive,91 cases (95.6％) with decreased C3 complement,71 cases (74.7 ％) with anti-dsDNA antibody positive,71 cases(74.7％) with decreased C4 complement,69 cases(72.6％) with anti-SSA antibody positive,62 cases (65.3％) with anti-Sm antibody positive,52 cases (54.7％) wiht proteinuria,anti-SSB antibody positive 49 cases(51.6％),46 cases (48.4％) with decreased leukocyte,38 cases(40.0％) with anti-nucleosome antibody,38 cases (40.0％) with anemia,26 cases(27.4％) with hematuresis,14 cases(14.7％) with decreased platelet,6 cases(6.3％) with injury of renal function.Renal injury,anti-Sm antibody and anti-nucleosome antibody of male children with SLE were significantly higher than those of female children(x2 =9.989,4.224,4.070,all P ＜ 0.05).The positive rate of anti-SSB antibody in female children with SLE was significantly higher than that of male children(x2 =3.885,P ＜ 0.05).Conclusions Male childre with SLE are easy to appear the renal injury,proteinuria is the most common.Anti-Sm antibody is a risk factor for the high incidence of renal injury in male children with SLE.Anti-nucleosome antibody is a risk factor for the high incidence of SLE disease activity in male children than that of female children.The risk of future Sjogren's syndrome in female children with SLE is higher than that of male children.
