Clinical and pathological features of Henoch-Sch?nlein purpura nephritis in children / 临床儿科杂志

ABSTRACT

Objective To investigate the clinical and pathological features of Henoch-Sch?nlein purpura nephritis (HSPN) in children. Methods The clinical and pathological data of 242 children with HSPN admitted from January 2009 to January 2014 were retrospectively analyzed. Results The most common clinical type was proteinuria and hematuria (135 cases, 55.79%). The mainly pathological types were typeⅡandⅢ. The distribution of pathological types was statistically signiifcant between different clinical types (P=0.000). The patients with normal urine test had the lowest pathological grade. The patients with isolated hematuria and proteinuria mainly had pathological typeⅡ. The patients with hematuria and proteinuria mainly had pathological typeⅢa. The patients with nephrotic syndrome mainly had pathological typeⅢb. The length of the courses at renal biopsy was not statistically signiifcant among different clinical types (P>0.05) and pathological types (P>0.05). The deposition of immune complex in kidney was not statistically signiifcant among different pathological types (P>0.05). The levels of IgA, C3, and platelet count were not statistically signiifcant among different clinical and pathological types (P>0.05). Conclusion The clin-ical classiifcation is related to the pathological grade in children with HSPN.
