概括

确定了全身性硬化症患者组,揭示了不同的临床表现和预后. 肺高血压在这些已识别的全身性硬化症队伍中显著影响了生存率.

科学领域:

类风湿病学类风湿病学
免疫学免疫学免疫学
肺部病理学肺部病理学

背景情况:

系统性硬化症 (SSc) 是一种复杂的自身免疫性疾病,患病率和死亡率很高,主要是由扩散性间歇性肺病 (ILD) 和肺高血压 (PH) 等肺部并发症引起的.
异质呈现的SSc使得疾病过程的预测具有挑战性.
这项研究的重点是在严重系统性硬化症中创建同质的患者队列,以更好地了解预后.

研究的目的:

将患有严重系统性硬化症的患者分层成同质的子组.
分析每个子组内的临床特征和预后因素.
研究特定并发症 (如肺高血压和间歇性肺病) 对患者结局的影响.

主要方法:

在198名患有系统性硬化症的患者中进行了一项回顾性观察性研究.
使用自下而上的等级分类,根据与预后不佳相关的因素对患者进行分组.
患者数据包括临床表现,自身抗体概况,器官参与和职业暴露.

主要成果:

四个不同的患者集群出现了:集群1 (n=25) 患有PH和ILD的高患病率;集群2 (n=11) 患有硬质皮质危机和一些PH;集群3 (n=109) 主要是女性患者,皮肤SSc和抗中心抗体有限,没有严重的肺病;集群4 (n=53) 职业暴露,ILD和抗毒素酶I抗体.
在集群1中,存活率明显较低 (p < 0.001).
肺高血压是关键因素,与整个集群的不良预后相关.

结论:

系统性硬化症在临床表型和疾病轨迹方面表现出显著的异质性.
层次聚类有效地识别了具有不同预后的不同患者子组.
肺高血压的发展是系统性硬化症患者预后不佳的关键决定因素.

Psychological and Sociocultural Causes of Schizophrenia

Psychological and Sociocultural Causes of Schizophrenia

Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

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...
