K469EICAM-1 polymorphism was analyzed using PCR assay. Serum sICAM-1 was determined using ELISA rnebhod from 72 BA patients. In order to evaluate the association between these variables and their clinical outcome, the patients were categorized into two groups： patients without jaundice and those with persistent jaundice. RESULTS： There were no significant differences between BA patients and controls in terms of gender, K469E ICAM-1 genotypes, and alleles. The proportion of patients having serum sICAM-1 ≥3 500 ng/mL in persistent jaundice group was significantly higher than that in the other group. In addition, there was no association between K469EICAM-1 polymorphism and the status of jaundice in BA patients after Kasai operation. CONCLUSION： ICAM-1 possibly plays an important and active role in the disease progression. However, the process is not associated with genetic variation of K469E ICAM-1 polymorphism.展开更多
