Abstract
The aim of the study was to evaluate the cognitive and emotional development after pediatric liver transplantation. A total of 21 patients, aged 4-16.9 yr (median 9.6 yr) were tested 1-9 yr (median 4.2 yr) after the transplantation. The pretransplant diagnoses included biliary atresia (eight patients), various metabolic diseases (n = 6), acute liver failure (n = 3), and miscellaneous (n = 4). The cognitive functions were tested with Wechsler preschool and primary scale of intelligence (WPPSI)-R or Wechsler intelligence scale for children (WISC)-III according to age. The Piers-Harris self-concept scale and the evaluation of human figure drawings according to Koppitz were used to detect emotional problems. All tests in all patients were performed by the same psychologist. A significantly lower result on cognitive tests was seen when compared with the expected normal values (p < 0.01). The number of patients with results within or under the lower normal range was higher than expected. Although the mean value of the Piers-Harris self-concept scale was normal, there was a large spread within the group. Indicators of emotional problems were found in the human figure drawings of 50% of the patients. To some extent, low cognitive scores coincided with low scores on self-concept scale and indicators of emotional difficulties. We conclude that the high degree of cognitive and emotional problems after liver transplantation is an important argument for routine psychologic follow-up and support in these patients.
