概括
单边复发性初级中枢神经系统血管炎 (UR-PCNSV) 是一种罕见的亚型,其特征是单个半球内的复发. 这些患者通常需要加强免疫抑制,因为持续的炎症和血缩.
科学领域:
- 神经学 神经学
- 免疫学 免疫学 免疫学
- 血管医学 血管医学
背景情况:
- 单边复发性初级中枢神经系统血管炎 (UR-PCNSV) 是一种罕见的初级中枢神经系统血管炎 (PCNSV) 的亚型.
- 它的特征是经常出现的炎症性病变,仅限于单个大脑半球.
- 这项研究扩展了已知的UR-PCNSV表型,在文献中增加了三个新病例.
研究的目的:
- 进一步定义UR-PCNSV的临床和放射学表型.
- 为了增加这种罕见的神经疾病的现有病例系列.
- 在UR-PCNSV.中调查治疗反应和疾病进展.
主要方法:
- 两家三级推中心的诊所数据库的回顾性审查.
- 纳入标准:活检证明的PCNSV,单边病变,至少两次复发.
- 分析临床数据,神经成像 (MRI/CT血管学),脑脊液和组织病理学.
主要成果:
- 三个经过活检证明的UR-PCNSV病例被确定为复发性单边病变.
- 患者表现为头痛和单边神经缺陷;在1例中发现认知障碍.
- 组织病理学揭示了T细胞主导的淋巴细胞透物;尽管接受了抗CD20治疗,但发生了复发,需要长时间的免疫抑制,并在一年内导致血液缩.
结论:
- 与典型的PCNSV相比,UR-PCNSV的发病年龄较小,复发频繁.
- 较高的炎症活性和血缩表明需要强化免疫抑制,而不仅仅是抗CD20单疗.
- 与中枢神经系统脱髓化的重叠特征可能导致诊断延迟.

01:25Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
01:26Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
01:19Multiple 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...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
