Abstract

Purpose: It has been reported that children with hypopituitarism have features of metabolic syndrome, including obesity, impaired glucose tolerance, and dyslipidemia. The aim of this study was to investigate the clinical features and liver histology of pediatric non-alcoholic fatty liver disease (NAFLD) associated with hypopituitarism. Methods: We reviewed the clinical data of 11 children diagnosed with NAFLD among patients with hypopituitarism. Results: The mean age at the time of diagnosis of hypopituitarism was 10.4${\pm}$3.2 years, and the mean age at the time of diagnosis of NAFLD was 13.1${\pm}$2.7 years. A craniopharyngioma was the most common cause of pituitary dysfunction. At the time of diagnosis of NAFLD, 9 patients (82%) had a body mass index greater than the 85th percentile, 5 patients (45%) had elevated fasting blood glucose levels, and 9 patients (82%) had hypertriglyceridemia. The mean height SD score was significantly lower at the time of diagnosis of NAFLD than at the time of diagnosis of hypopituitarism. Of the six patients who were biopsied, one had cirrhosis, two had non-alcoholic steatohepatitis (NASH) with bridging fibrosis, two had NASH with mild portal fibrosis, and one had simple steatosis. Conclusion: Children with hypopituitarism are at risk of short stature, obesity, dyslipidemia, and NAFLD. The early diagnosis of NAFLD is important in children with hypopituitarism because advanced fibrosis is common.

목 적: 뇌하수체저하증 환아들은 비만, 당불내성, 고지질혈증을 포함한 대사증후군의 양상을 보인다. 이 연구의 목적은 뇌하수체저하증과 연관된 소아 지방간질환의 임상 양상과 간조직 소견을 알아보는 것이다. 방 법: 뇌하수체저하증 환자 중에서 비알코올성 지방간질환으로 진단된 소아 11명의 임상자료를 조사하였다. 결 과: 뇌하수체저하증 진단 시 연령은 10.4${\pm}$3.2세였다. 지방간질환 진단 시 연령은 13.1${\pm}$2.7세였다. 두 개인 두종이 뇌하수체저하증의 기저질환 중 가장 흔하였다. 지방간질환 진단 당시 체질량지수 85백분위수 이상이 9명(82%), 금식 시 고혈당이 5명(45%), 고지질혈증이 9명(82%)에서 발견되었다. 신장의 표준편차 점수의 평균은 뇌하수체저하증 진단 시보다 지방간질환 진단시에 유의하게 낮았다. 간생검을 실시한 6명 중에서 1명은 간경변, 2명은 연결 섬유화가 동반된 지방간염, 2명은 경도의 간문맥 섬유화가 동반된 지방간염, 1명은 단순 지방간으로 진단되었다. 결 론: 뇌하수체저하증을 가진 소아는 저신장, 비만, 고지질혈증, 비알코올성 지방간질환이 발생할 위험이 높다. 간조직의 진행된 섬유화가 흔하기 때문에 뇌하수 체저하증 환아에서 지방간질환의 조기 진단이 중요하다.
