研究目的:

本研究旨在系统阐明中国人群红细胞生成性原卟啉症(EPP)的临床及遗传学特征,并全面评估红细胞置换疗法在中国患者中的临床应用价值。具体而言,我们将通过分析中国EPP家系的FECH基因突变谱、等位基因异质性及单倍型特征,探索基因型与临床表型间的内在关联规律,为个体化风险评估提供依据。同时,通过观察单次及系列红细胞置换治疗对患者红细胞原卟啉水平的动态影响,评估该疗法在改善临床症状的潜在效益,并系统监测治疗相关不良反应,以全面评价其临床应用的安全性特征。  

Objectives of Study:

This study aims to systematically clarify the clinical and genetic characteristics of erythropoietic protoporphyria (EPP) in the Chinese population, and comprehensively evaluate the clinical application value of red blood cell exchange transfusion in Chinese patients. Specifically, we will analyze the FECH gene mutation spectrum, allelic heterogeneity, and haplotype characteristics of Chinese EPP families to explore the inherent correlation between genotypes and clinical phenotypes, thereby providing a basis for individualized risk assessment. Meanwhile, by observing the dynamic effects of single and serial red blood cell exchange transfusions on patients' erythrocyte protoporphyrin levels, we will assess the potential benefits of this therapy in improving clinical symptoms and systematically monitor treatment-related adverse reactions to comprehensively evaluate the safety profile of its clinical application.
