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. |

纳入标准: |
EPP患者组纳入标准:1.临床符合EPP诊断:基因测序示亚铁螯合酶(FECH)基因异常;红细胞原卟啉含量明显升高,超过正常值(<80μg/dL红细胞)的3-4倍。2.年龄18-75岁,性别不限。3.自愿签署知情同意书,能配合完成随访及相关检查。4.无红细胞置换治疗禁忌症(包括:严重凝血功能障碍、严重贫血Hb<80g/L、对血液制品过敏、严重感染未控制等)。 健康对照组纳入标准:1.无慢性疾病史(包括但不限于心血管疾病、肝病、血液病、卟啉病等);2.红细胞原卟啉<80μg/dL红细胞;3.年龄 18-75 岁,与 EPP 患者组性别、年龄分布匹配;4.自愿签署知情同意书。5.不调用医院生物样本库中的健康血样(因红细胞游离原卟啉具有见光易分解、随时间延长会发生降解的特性,库存血样无法保证检测结果的准确性,为确保研究数据可靠,仅采集新鲜血样)。 |

|
Inclusion criteria |
Inclusion Criteria for the EPP Patient Group 1.Clinically confirmed diagnosis of EPP: Genetic sequencing reveals ferrochelatase (FECH) gene abnormalities; erythrocyte protoporphyrin levels are significantly elevated, 3–4 times higher than the normal reference value (< 80 μg/dL red blood cells). 2.Aged 18–75 years, with no gender restrictions. 3.Voluntarily sign the informed consent form and be able to cooperate with follow-up visits and relevant examinations. 4.No contraindications to red blood cell exchange transfusion, including severe coagulation disorders, severe anemia (hemoglobin < 80 g/L), hypersensitivity to blood products, and uncontrolled severe infections. Inclusion Criteria for the Healthy Control Group 1.No history of chronic diseases, including but not limited to cardiovascular diseases, liver diseases, hematological disorders, and porphyrias. 2.Erythrocyte protoporphyrin level < 80 μg/dL red blood cells. 3.Aged 18–75 years, with gender and age distribution matched to the EPP patient group. 4.Voluntarily sign the informed consent form. 5.Healthy blood samples from the hospital biobank are excluded. Given that free erythrocyte protoporphyrin is photolabile and susceptible to degradation over time, stored blood samples cannot guarantee the accuracy of test results. To ensure the reliability of research data, only fresh blood samples are collected. |

排除标准: |
EPP患者组排除标准:1.合并心、肾、脑等其他严重脏器功能衰竭。2.存在红细胞置换禁忌症。3.妊娠或哺乳期妇女。4.急性发作伴严重感染及意识不清者。5.拒绝配合新鲜外周血采集者及血液检查者。 健康对照组排除标准:1.符合EPP患者组排除标准①-④。2.有卟啉病家族史或亲属确诊EPP者。3.近3个月内有重大手术史、输血史或服用可能影响卟啉代谢的药物(如某些抗生素、抗癫痫药)者。4.拒绝配合新鲜外周血采集者及血液检查者。 |
||||||||||||||||||||||
|
Exclusion criteria: |
Exclusion Criteria for the EPP Patient Group: 1.Complicated by cardiac, renal, cerebral or other severe organ failure: 2.Has contraindications to red blood cell exchange transfusion; 3.Pregnant or lactating women; 4.Those with acute episode complicated by severe infection and altered consciousness; 5. Those who refuse to cooperate with the collection of fresh peripheral blood and blood tests. Exclusion Criteria for the Healthy Control Group: 1.Meeting criteria 1–4of the exclusion criteria for the EPP patient group. 2.Having a family history of porphyria or relatives diagnosed with EPP. 3.Having a history of major surgery, blood transfusion, or administration of drugs that may affect porphyrin metabolism (e.g., certain antibiotics, antiepileptic drugs) within the recent 3 months. 4.Those who refuse to cooperate with fresh peripheral blood collection and blood tests. |
