Objective: To investigate the clinical efficacy of liver transplantation in the treatment of acute liver in children with NBAS gene deficiency disease and their outcome. Methods: This retrospective study enrolled children with NBAS gene deficiency who were admitted to the Children's Hospital of Fudan University for liver transplantation from January 2013 to June 2022. The clinical data were collected and analyzed. Medical literature published before June 2022 was searched with the keywords of "NBAS" "neuroblastoma amplified sequence recurrent" "acute liver failure" "SOPH syndrome" "short stature with optic nerve atrophy" "Pelger-Huët anomaly" in PubMed, China National Knowledge Infrastructure and Wanfang database. Results: Liver transplantation was performed in 3 patients (2 males and 1 female) with NBAS deficiency. All patients presented with fever-triggered recurrent acute liver failure. The genetic detection found compound heterozygous NBAS gene pathogenic variants in them. The total episodes of acute liver failure before liver transplantation were 11, 2, and 4 respectively, and the age at liver transplantation was 3.5, 2.3, and 2.0 years respectively. During liver transplantation, patient 1 was in the convalescent phase of acute liver failure, patient 2 was in the acute phase, presenting with hepatic encephalopathy (grade V) and respiratory failure, and patient 3 was considered to be in the acute phase. After liver transplantation, patient 1 recovered normal liver function within 1 month and had no liver transplantation-related complications. Patient 2 had secondary epilepsy, intellectual disability, movement disorder, and transiently elevated transaminases. Patient 3 died of severe infection within 1 month. There was no literature in Chinese, 6 in English, 8 NBAS-deficient patients who were treated with liver transplantation. Total 11 patients presented with fever-triggered recurrent acute liver failure. Their age at liver transplantation ranged from 0.9 to 5.0 years. Postoperative complications occurred in 3 patients. Until the last visit, they were followed up for 0.7 to 14.0 years. Total 2 patients died and the 9 surviving patients did not develop acute liver failure. Conclusions: Liver transplantation is effective for the treatment of acute liver failure associated with NBAS gene disease. However, postoperative complications of liver transplantation may occur. The timing of liver transplantation still needs further research.
目的： 探讨肝移植治疗儿童NBAS基因缺陷病急性肝衰竭的临床疗效和预后。 方法： 回顾性病例总结2013年1月至2022年6月就诊于复旦大学附属儿科医院并行肝移植手术的3例NBAS基因缺陷病患儿的临床资料，并分别以“NBAS”“neuroblastoma amplified sequence recurrent”“acute liver failure”“SOPH syndrome”“short stature with optic nerve atrophy and Pelger-Huët anomaly”“发热相关肝衰竭”“急性肝衰竭”为关键词检索PubMed、万方数据库、中国知网数据库建库至2022年6月关于NBAS基因缺陷病肝移植的病例报道，总结其临床疗效和预后。 结果： 3例NBAS基因缺陷病患儿行肝移植治疗，男2例，女1例。3例患儿临床表型为发热相关的反复急性肝衰竭，基因结果为NBAS基因复合杂合致病变异。肝移植前急性肝衰竭次数分别为11、2和4次，手术年龄分别为3.5、2.3和2.0岁。肝移植时，例1为肝衰竭恢复期，例2为肝衰竭急性期肝性脑病Ⅴ期和呼吸衰竭，例3可能为肝衰竭急性期。肝移植后，例1于1个月内肝功能恢复正常，无术后并发症。例2出现癫痫、精神运动发育落后和暂时性转氨酶升高。例3于1个月内死于脓毒症。文献检索未见中文文献，6篇英文文献报道8例行肝移植手术的NBAS基因缺陷病患儿。结合本组3例患儿，11例患儿均表现为发热相关的反复急性肝衰竭，肝移植年龄为0.9~5.0岁。3例患儿出现术后并发症。截至末次随访，11例患儿随访时间为0.7~14.0年，2例患儿死亡，9例患儿存活并无肝衰竭。 结论： 肝移植是治疗NBAS基因缺陷病肝衰竭有效的措施，但术后可能出现肝移植相关并发症，NBAS基因缺陷肝衰竭肝移植时机仍需进一步研究。.
