Abstract:
Objective To investigate the clinical,renal pathological characteristics of Henoch Sch(O)nlein purpura nephritis (HSPN) in children.Methods One hundred and sixty-seven children hospitalized with HSPN from Jan.2008 to Dec.2011 in the First Affiliated Hospital of Zhengzhou University were divided into 2 groups by 24-hour urinary protein quantity:group A with 24-hour urinary protein quantity ＜ 25 mg/kg,group B with 24-hour urinary protein quantity ≥ 25 mg/kg.Age of onset,gender,injury time of kidney,clinical manifestations,24-hour urinary protein quantity and renal pathological grades of the 2 groups were collected and analyzed.Results In 167 HSPN children,the ratio of male to female was 1.8:1.0.The ages from 5 to 10 years old accounted for 70.7％.Renal injurytime was from a day to 5 months,91.6％ of the HSPN children occurred renal damage within 1 month.HSPN children had clinical signs of gastrointestinal involvement in 56 cases(33.5％),at the same time,the digestive tract and joint involvement in 52 cases(31.1％).Pathological classification of 6 grades:8 cases(4.8％) of grade Ⅰ ;32 cases(19.2％) of grade Ⅱ ;124 cases (74.3 ％) of grade Ⅲ ;3 cases (1.8％) of grade Ⅳ ; no grade Ⅴ or Ⅵ.Pathologic grade of group B was higher than group A,and the difference was significant (P ＜ 0.05).Conclusions The HSPN children,expecially the boys,were more found with digestive tract injury or multiple organ damage.Most HSPN children occurred renal damage within 1 month.The renal biopsy of HSPN children should be positive,especially when the 24-hour urinary protein quantity is ≥25 mg/kg.
