Limited Competition for the Continuation of the Childhood Liver Disease Research Network (ChilLDRen) Clinical Centers.

尽管每一种都是相对罕见的，先天性淤胆性肝病共同影响着儿科 健康状况显著。其中，胆道闭锁(BA)是儿科最常见的病因。 终末期肝病和儿童肝移植的主要适应症。这个 儿童肝病研究网络(CHILDS)成立于2009年，旨在扩大 胆道闭锁研究联盟研究众多罕见先天性胆汁淤积症的范围 肝脏疾病包括Alagille综合征，进行性家族性肝内胆汁淤积症，A1- 抗胰蛋白酶缺乏症、线粒体肝病和胆盐合成缺陷。从那以后， NIDDK资助的财团报告了许多高影响的观察结果。 原发硬化性胆管炎目前正被该网络列为重点疾病。 洛杉矶儿童医院(CHLA)临床研究中心一直非常活跃 网络努力的方方面面。在这份申请中，我们重申我们致力于改善 先天性肝病患者的临床结局。这个项目的总体目标是 应用程序通过以下方式影响罕见肝病儿童的存活率：(1) 受试者参加儿童联合会内的各种临床研究和试验，以及(2)a 翻译辅助研究的重点是辅酶Q10，作为肝纤维化的生物标志物。中环 目标2的假设是血清辅酶Q10水平与肝纤维化程度相关。这 项目具有创新性，因为(1)CHLA拥有唯一的儿科首席调查员 外科医生，从而为指导委员会提供外科洞察力和视角 (2)辅酶Q10是一种新的潜在的肝纤维化生物标志物。

Albeit each is relatively rare, congenital cholestatic liver diseases collectively impact pediatric health significantly. Amongst them, biliary atresia (BA) is the most common cause of pediatric end-stage liver disease and the leading indication for pediatric liver transplantation. The Childhood Liver Disease Research Network (ChiLDReN) was established in 2009 to expand the scope of the Biliary Atresia Research Consortium to study numerous rare congenital cholestatic liver diseases including Alagille syndrome, Progressive Familial Intrahepatic Cholestasis, a1- Antitrypsin Deficiency, Mitochodrial Hepatopathies, and Bile Salt Synthesis Defects. Since then, numerous high impact observations have been reported by the NIDDK-funded consortium. Primary Sclerosing Cholangitis is currently being added as a disease of focus by the network. The Children’s Hospital Los Angeles (CHLA) clinical research center has been very active in all aspects of the network’s efforts. In this application, we restate our commitment to improve the clinical outcomes of patients with congenital liver diseases. The overall objectives of this application are to impact survival of children with rare liver diseases via (1) the enrollment of subjects into the various clinical studies and trials within the ChiLDREN consortium and (2) a translational ancillary study focused on CoQ10, as a biomarker of liver fibrosis. The central hypothesis of objective #2 is that serum levels of CoQ10 correlate with extent of liver fibrosis. This project is innovative because (1) CHLA has the only Principal Investigator who is a pediatric surgeon, thus providing surgical insight and perspective for a Steering Committee otherwise comprised of pediatric hepatologists and (2) CoQ10 is a novel potential biomarker for liver fibrosis.
