概括

血友病的低剂量预防 (LDP) 与较低的国民收入和全民医疗覆盖率有关,这表明成本驱动在资源较低的国家采用,特别是儿童. 这突显了全球在血友病治疗获得的差异.

科学领域:

血液学血液学血液学
药理动力学药理动力学
全球健康全球健康

背景情况:

血友病的治疗,特别是因子VIII (FVIII) 预防,是昂贵的,全球只有25%的患者获得足够的护理.
使用FVIII的低剂量预防 (LDP),虽然不是最佳的,但可以降低年度关节出血率.
了解与人均国民总收入 (GNI) 和全民健康覆盖指数 (UHCI) 等经济指标相关的FVIII使用模式,对于解决全球差距至关重要.

研究的目的:

为了总结FVIII使用情况,LDP患病率,GNI和UHCI,使用Web可访问人口药物动力学服务-血友病 (WAPPS-Hemo) 平台 (2017-2023) 的数据.
估计儿科 (≤12岁) 和成人血友病患者的LDP (P_LDP) 和GNI/UHCI概率之间的关系.
在LDP和非LDP患者之间进行药理动力学 (PK) 概况的探索性比较.

主要方法:

用描述性统计数据和图形总结来分析FVIII使用,LDP流行,GNI和UHCI.
混合效应物流回归模型被用来估计P_LDP和GNI/UHCI之间的关联.
在LDP状态中对PK结果进行了探索性比较.

主要成果:

来自6223名严重血友病患者的数据显示,18%的国家 (儿童) 和32% (成人) 使用≤1%的LDP输液.
每年LDP的患病率都在增加,在儿童中达到7%的高峰,在成年人中达到14%.
在儿科和成人群体中观察到P_LDP和GNI和UHCI之间存在显著的反向关联. 在LDP组中,PK结果通常是相似的,在儿童中,血衍生产品可能是一个例外.

结论:

在WAPPS-Hemo数据库中,低资源国家的代表性不足凸显出血友病护理的重大财务障碍.
GNI/UHCI和P_LDP之间的反向关系表明,成本是影响LDP采用的主要因素,特别是在资源较低的环境中的儿科病例中.
在LDP状态中观察到的药理学相似性可能支持在WAPPS-Hemo所代表的环境中更广泛地实施LDP.

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
