Objectives To study hemolytic Streptococcus infection relationship with Henoch-Schonlein Purpura in children.
Methods 42 cases in children with Henoch-Schonlein Purpura (Observer Group) and healthy children in 40 cases of physical examination (the control group) for blood antistreptolysin O (ASO) detection, observation group at the same time children are divided into (belly-non-abdominal Purpura and Purpura group set and repeatedly attacks groups and the Group of non-recurrent) for statistical analysis.
Results Observation group in the blood ASO detection positive 22 cases, accounted for 52.4%; normal control group children 40 cases, blood ASO detection positive 2 cases, accounted for 5%, both comparison differences has significantly significance (χ2=22.22, p<0.01); abdominal type Purpura children with 23 cases, blood ASO detection positive 17 cases, accounted for 73.9%; non-abdominal type Purpura children with 19 cases, blood ASO detection positive 5 cases, accounted for 26.3%, both comparison differences has significantly significance (χ2=9.45, p<0.01); 14 cases in children with recurrent Henoch-Schonlein Purpura, ASO blood test positive in 12 cases, 85.7%, non-recurrent attacks of 28 cases of children with Henoch-Schonlein Purpura, ASO blood test positive in 10 cases, 35.7%, comparing the two differences are significant (χ2=9.35, p<0.01).
Conclusions Streptococcal infections may be the important factor relatated to Henoch-Schonlein Purpura in children.Purpura and Purpura of abdominal type recurrence is related with streptococcal infection, which is the great value to treatment.
