Abstract:
Objective To analyze the risk factors of early renal damage in children with Henoch Schonlein purpura(HSP).Methods The clinical data of 196 children with HSP admitted to our hospital from April 2012 to January 2016 were analyzed retrospectively.They were divided into the renal damage group and non-renal damage group within 90 d after confirmed diagnosis.The related clinical data such as serum immunoglobulin and urinary microalbumin were compared between the two groups,and the risk factors of early renal damage in children with HSP were screened.Results There were significant differences between the two groups on age,joint symptoms,recurrent purpura,persistent rash,gastrointestinal bleeding and abdominal pain(with χ2 or t of 11.345,16.223,11.275,43.211,12.592,17.771,P<0.05).The white blood cell count,platelet count,immunoglobulin A(IgA) level and urinary albumin level also showed significant differences between the two groups(t=33.750,60.442,9.451,8.458,P<0.05).The multivariate regression analysis showed that the independent risk factors for early renal damage in children with HSP included age(OR=2.703),recurrent purpura(OR=2.721),persistent skin rash(OR=1.782),gastrointestinal bleeding(OR=11.472),abdominal pain(OR=2.046),IgA level(OR=1.221) and urine microalbumin(OR=3.214).Conclusion Age,recurrent purpura,persistent skin rash,gastrointestinal bleeding,abdominal pain,IgA level and urine microalbumin are closely related to early renal damage in children with HSP.
