概括

在多发性硬化症 (MS) 患者中,自主造血干细胞移植 (AHSCT) 可能导致胸腺增生,表明胸腺再生. 这一发现支持AHSCT.

科学领域:

免疫学免疫学免疫学
放射学放射学是一门学科.
神经学神经学

背景情况:

在自身免疫性疾病中,对自身免疫性干细胞移植 (AHSCT) 后的胸膜形成的重新激活对于免疫复原至关重要.
之前的研究报告了在系统性硬化症中AHSCT后的胸膜增生,但在多发性硬化症 (MS) 中没有.
多发性硬化症患者可能会经历由于疾病修饰治疗 (DMT) 和过早的胸腺内置而导致的加速免疫衰变.

研究的目的:

为了调查在经过自身造血干细胞移植 (AHSCT) 后多发性硬化症 (MS) 患者中胸膜增生的发生情况.
评估胸膜激活的放射证据,作为MS中AHSCT后免疫复合的指标.

主要方法:

在AHSCT (BEAM/ATG疗法) 后进行胸部CT扫描的MS患者的单心病例系列.
胸膜增生是由CT扫描的特定放射学标准 (圆形质量,~40HU密度,厚度>1.3厘米) 定义的.
胸部CT检查的审查由胸部放射科医生进行.

主要成果:

在AHSCT后1-3个月内,在15名多发性硬化患者中,有3名 (20%) 检测到胸膜增生症.
所有患有胸膜增生症的患者都是女性,年龄在30-40岁之间.
胸膜增生和临床人口因素或AHSCT后结果之间没有发现联系,包括感染或二次自身免疫.

结论:

在接受AHSCT治疗的多发性硬化患者中,胸腺增生发生在20%的患者中,这表明胸腺再生.
这些发现与免疫学研究一致,这些研究表明在MS中AHSCT诱导的胸腺激活.
这支持了 de novo 胸膜形成在MS的AHSCT后免疫复原中的作用.

Bone Marrow Sampling and Transplants

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Multiple Sclerosis l: Introduction

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
