ABSTRACT
Objective To evaluate the outcome of long-term cognitive function after liver transplan-tation in children and the role of age factor.Methods Ninety-five pediatric patients,aged 2 yr and 6 months to 6 yr and 11 months at test,at least 1 yr after liver transplantation,were selected.The children's cognitive function was assessed using Chinese Wechsler Intelligence Scale for Children.The patients were divided into 2 groups according to the age at transplantation: ≤1 yr group(L1 group,n＝65)and > 1 yr group(M1 group,n＝22).Results Compared with the normal value,the scores of verbal comprehension and total intelligence quotient(IQ)were significantly decreased,and the proportion of children who had a-bove-average IQ was decreased 1 yr after liver transplantation,the scores of verbal comprehension were de-creased,and the proportion of children who had above-average IQ was decreased in group L1,and the scores of verbal comprehension,visual space and total IQ were significantly decreased,the proportion of children who had above-average IQ was reduced,and the proportion of children who had below-average IQ was increased in group M1(P＜0.05).Compared with L1 group,the total IQ score was significantly de-creased,the proportion of children who had above-average IQ was reduced,and the proportion of children who had below-average IQ was increased in group M1(P＜0.05).Conclusion The long-term cognitive function of children after liver transplantation is lower than that of normal children,and the long-term cogni-tive function of children ≤1 yr is better than that of children >1 yr.
ABSTRACT
Objective@#To evaluate the outcome of long-term cognitive function after liver transplantation in children and the role of age factor.@*Methods@#Ninety-five pediatric patients, aged 2 yr and 6 months to 6 yr and 11 months at test, at least 1 yr after liver transplantation, were selected.The children′s cognitive function was assessed using Chinese Wechsler Intelligence Scale for Children.The patients were divided into 2 groups according to the age at transplantation: ≤1 yr group (L1 group, n=65) and > 1 yr group (M1 group, n=22).@*Results@#Compared with the normal value, the scores of verbal comprehension and total intelligence quotient (IQ) were significantly decreased, and the proportion of children who had above-average IQ was decreased 1 yr after liver transplantation, the scores of verbal comprehension were decreased, and the proportion of children who had above-average IQ was decreased in group L1, and the scores of verbal comprehension, visual space and total IQ were significantly decreased, the proportion of children who had above-average IQ was reduced, and the proportion of children who had below-average IQ was increased in group M1(P<0.05). Compared with L1 group, the total IQ score was significantly decreased, the proportion of children who had above-average IQ was reduced, and the proportion of children who had below-average IQ was increased in group M1 (P<0.05).@*Conclusion@#The long-term cognitive function of children after liver transplantation is lower than that of normal children, and the long-term cognitive function of children ≤1 yr is better than that of children >1 yr.
