Abstract
Objectives : We examined whether D8/17 expression in Tourette syndrome children who suggested PANDAS were higher than comparison group, and there was my clinical difference by D8/l7 expression. Methods : Nine Tourette's syndrome children suggested PANDAS and two ADHD children without tic disorder were evaluated far percentage of D8/17 expression-positive B cells by immunofluorescence flow cytometric assay and anti-streptolysin O titer. Results : The frequency of D8/17 positive B lymphocyte rate was significantly higher in Tourette's syndrome than ADHD, whose average rate were 77.9 and 24.8, respectively. Among 9 TD patients,4 patients showed above 90% D8/l7 expression. There was high concordance expression rate between mother (98.4%) and daughter (99.0%) The significant relation between percentage of D8/17 expression and tic severity were not detected. The significant relation between percentage of D8/17 expression and anti-streptolysin O titer were not detected, however in 66.7% TD patients showed above 100IU/ml. Conclusion : We concluded that subgroup of TD children are streptococcal infected tic disorder, so called PANDAS.
연구목적 : Streptococcus 감염에 취약한 생물학적 지표라고 알려진 D8/17 항체가 PANDAS로 의심되는 뚜렛장애 환자에서 높은지를 알아보고, 뚜렛장애군 중 D8/17 양성반응 여부에 따라 임상경과에 차이가 있는지를 알아보고자 본 연구를 시행하였다. 방 법 : PANDAS가 의심되는 뚜렛장애 소아환자 9명과 비교 대상으로 틱증상이 없이 일관되게 지속적으로 주의력결핍 과잉 행동장애를 보이는 2명의 소아를 택하여 B 임파구 D8/17 항원 양성반응 비율과 혈청 ASO 농도를 비교분석하였다. 결 과 : PANDAS가 의심되는 9명의 뚜렛장애 소아의 경우 평균 77.9%(
