Study clinical and subclinical features of Henoch-Schönlein purpura in children Objective: Describe clinical and subclinical characteristics of Henoch-Schönlein purpura in children.

Methods: Cross-sectional descriptive study, including 51 children <15 years of age diagnosed with Schonlein-Henoch purpura being treated at Hue Central Hospital and Hue University Hospital from April 2016 - May 2018.

The most frequent laboratory abnormalities were Leukocytosis (WBC >10 x 109/L) in 60,8%, high-erythrocyte sedimentation rate (ESR) in 80.4%, microscopic hematuria in 15.7%, proteinuria in 13.7%. Renal lesion were correlated with age of onset. The age group> 10 years old has 6.1 times more kidney lesion than the group ≤ 10 years (OR: 6.1; 95% CI (1.5-26).
