研究目的: |
评估儿童ITP患者接受TPO-RA治疗后骨髓纤维化的发生率及严重程度分布,并识别与BMF发生相关的临床及治疗危险因素(如TPO水平、TPO-RA种类、疗程、超剂量使用等)。 |
||||||||||||||||||||||
|
Objectives of Study: |
Evaluate the incidence and severity distribution of bone marrow fibrosis in children with ITP after receiving TPO-RA treatment, and identify the clinical and treatment-related risk factors associated with the development of BMF (such as TPO levels, types of TPO-RA, treatment duration, and overdose use, etc.) |

纳入标准: |
1. 年龄1-18岁。 2. 符合《中国儿童原发性免疫性血小板减少症诊断与治疗改编指南(2021年版)》诊断标准。 3. 至少接受过一种TPO-RA(如艾曲泊帕、罗普司亭、阿伐曲泊帕)治疗。 4. TPO-RA治疗启动后完成了骨髓活检,且具备完整的网织纤维染色(Gomori银染)病理报告及纤维化分级。 |
||||||||||||||||||||||
|
Inclusion criteria |
1. Age 1–18 years. 2. Meets diagnostic criteria outlined in the Revised Chinese Guidelines for Diagnosis and Treatment of Primary Immunological Thrombocytopenia in Children (2021 Edition). 3. Has received treatment with at least one TPO receptor antagonist (e.g., eltrombopag, roux-Vorspin, avatrombopag). 4. Completed bone marrow biopsy following initiation of TPO-RA therapy, with a comprehensive pathological report including reticulin fibre staining (Gomori silver staining) and fibrosis grading. |
||||||||||||||||||||||
|
排除标准: |
1. 诊断为继发性ITP(如继发于系统性红斑狼疮、 Evans综合征等)或合并其他明确的血液系统疾病(如骨髓增生异常综合征、遗传性血小板减少症等)。 2. 临床病历资料或骨髓病理资料缺失关键信息,无法进行有效分组或分析。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. Diagnosed with secondary ITP (e.g., secondary to systemic lupus erythematosus, Evans syndrome, etc.) or coexisting with other clearly defined haematological disorders (e.g., myelodysplastic syndromes, hereditary thrombocytopenia, etc.). 2. Critical information is missing from clinical case records or bone marrow pathology data, rendering effective grouping or analysis impossible. |
