Abstract:
Objective To investigate the relationship between urine IgG of the first hospitalized children suffered allergic purpura and recurrence within one year. Methods Used immunoturbidimetry to determine acute-stage and convalescent urine IgG of 43 children suffered allergic purpura in the first hospitalized and no recurrence within one year (no recurrence group), and of 29 children suffered allergic purpura and recurrence within one year (recurrence group), and of 28 hospitalized children suffered primary nephrotic syndrome during the corresponding time period before hormonal therapy (nephrotie syndrome group), and of 30 children done medical examination in out-patient clinic (control group), then analyzed.Results There was no significant difference of the urine IgG level in acute-stage between no recurrence group [(1.391± 0.743) g/L] and recurrence group [(1.474 ±0.658) g/L](P>0.05), while they were all lower than that in recurrence group [(2.808 ± 0.683) g/L] (P < 0.01). The level of convalescent urine IgG in nephrotic syndrome group [(0.202 ± 0.154) g/L] was obviously higher than that in no recurrence group [(0.115 ±0.103) g/L] and control group [(0.109 ±0.098) g/L](P<0.05). Conclusion Urine IgG is a significant index to judge the activity and recurrence and prognosis of pedo-allergie purpura.
