超大型脂质数据库 (VLDL) (VLDL)
超大型脂质数据库 (VLDL):临床实验室大数据项目
对大量人群中的颗粒脂质数据进行更仔细的检查提供了许多产生新知识的机会,范围从检查常用脂质参数之间一致性的研究到罕见或极端脂质代谢紊乱的表型特征,为未来更好地个性化异常血液治疗开辟了可能性脂质。
研究人群:
超大型脂质数据库 (VLDL) 包括临床转诊进行垂直自动配置文件 (VAP) 的成人和儿童。 患者样本主要来自美国的门诊初级保健诊所 (85%),以及专科诊所和住院环境。
脂质测量:
VAP 测试(VAP 诊断实验室,伯明翰,阿拉巴马州,美国)直接测量低密度脂蛋白、极低密度脂蛋白、中密度脂蛋白、高密度脂蛋白及其亚组分和脂蛋白 (a) 的胆固醇浓度。 数据库中的甘油三酯是使用 Abbott ARCHITECT C-8000 系统(美国伊利诺伊州 Abbott Park)直接测量的。 数据库中的脂质分布与具有代表性的全国健康和营养检查调查 (NHANES) 中的脂质分布非常匹配。
研究程序:
该数据库由研究者发起。 只有去识别化的数据才能到达调查站点。 主数据库位于马里兰州巴尔的摩的约翰霍普金斯医院,由 Drs 维护。 琼斯和马丁。 当前数据库(第二次收获)包括 5,051,467 名患者,其实验室样本是从 2015 年 10 月 1 日和 2019 年 6 月 30 日收集的。 只有电子数据,而不是血液样本,被发送到霍普金斯大学。 学术研究人员可以不受限制地访问研究数据,对分析的准确性负责,并对手稿的准备和提交拥有权力。
变量:
目前 VLDL 数据库中的变量是测试日期、年龄、性别、空腹/非空腹和 VAP 测试的组成部分。 从这些主要变量中,衍生出许多附加变量以包含在主数据库中。 通过 VLDL 数据库子集中经过验证的测定法测量的其他分析物包括载脂蛋白 B (apoB)、载脂蛋白 A1 (apoAI)、高灵敏度 C 反应蛋白 (hsCRP)、同型半胱氨酸、尿酸、胰岛素、血红蛋白 A1c、25-羟基维生素D、胱抑素C、脂蛋白相关磷酸酶(Lp-PLA2)、促甲状腺激素(TSH)、游离T3和T4、促脑利钠肽(pBNP)、直接胆红素、磷酸肌酸激酶(CPK)、肌酐等成分综合代谢组、镁和磷酸盐。
