概括
在混合结缔组织疾病 (MCTD),具有自身免疫特征的间歇性肺炎 (IPAF) 和系统性硬化症 (SSc) (VEDOSS) 的非常早期诊断中,诊断时的标准不能预测到SSc的进展. 然而,抗脂抗体和低补体水平预测了系统性红斑狼 (SLE) 的演变.
科学领域:
- 类风湿病学 类风湿病学
- 免疫学 免疫学 免疫学
- 内部医学 内部医学
背景情况:
- 混合连接组织疾病 (MCTD) 通常被认为是差异化连接组织疾病 (dCTD) 的潜在早期,非特异性阶段.
- 需要进一步澄清的是,MCTD与具有自身免疫特征的间歇性肺炎 (IPAF) 和系统性硬化症的非常早期诊断 (VEDOSS) 等疾病之间的关系.
- 了解MCTD演变对于准确的诊断和患者管理至关重要.
研究的目的:
- 评估IPAF,VEDOSS和当前dCTD分类标准在被诊断为MCTD的患者中的预测价值.
- 确定特定的临床和血清学标记,预测MCTD向其他dCTD的进展,特别是系统性硬化症 (SSc) 和系统性红斑狼 (SLE).
主要方法:
- 通过使用法国MCTD队列的数据进行了一项观察性研究.
- 患者根据IPAF,VEDOSS和在MCTD诊断时现有的dCTD分类标准进行分类.
- 进行了纵向跟踪,以追踪疾病的进展.
主要成果:
- 在324名MCTD患者中,随访时间中位数为8年,其中111名 (34.3%) 进展为dCTD (50名SSc,40名SLE,11名Sjögren病).
- 在诊断时满足IPAF或VEDOSS标准并不能显著预测SSc.的进展.
- 抗脂抗体和基线较低的C3/C4水平预测了SLE的演变 (分别为p=0.01和p=0.04).
结论:
- 在MCTD诊断时的IPAF和VEDOSS标准不是SSc.进展的可靠预测标准.
- 抗脂抗体和低补充血 (低C3/C4) 是MCTD演变为SLE的显著预测因素.
- 目前的证据表明,将MCTD患者排除在IPAF和VEDOSS分类之外,以改进这些疾病的诊断标准.

Classification of Connective Tissues
14.6K
The connective tissues have different properties and functions in the human body. They are broadly categorized into proper, supporting, or fluid connective tissues.
Connective Tissue Proper
Connective tissue proper is the most abundant class of connective tissues. As its name implies, it predominantly connects different tissues in the body. Depending on the cell types, ground substance, viscosity, and fiber types in the ECM, connective tissue proper is further categorized into loose and dense....

Connective Tissue Cell Types
4.0K
Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...

Introduction to Connective Tissues
13.3K
Connective tissues are one of the four main tissue types in humans that are extensively present in the body. They are characterized by cells embedded in an extracellular matrix (ECM) composed of a ground substance and three main types of protein fibers— collagen, elastic, and reticular fibers. The ground substance of connective tissues can range from a watery and jelly-like consistency to mineralized and hard. The wide variety of cells in the connective tissues include fibroblasts,...

Cardiomyopathy I: Introduction and Classification
498
Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...

Overview of Connective Tissues Proper
9.6K
Connective tissue proper is a class of connective tissue that encompasses all mature connective tissues except bone, cartilage, blood, and lymph. This extensive class of tissues has two subclasses — loose and dense connective tissues — classified based on the protein fiber arrangement and the amount of ground substance.
The loose connective tissues have a meshwork of thin collagen and elastin fibers, which provide tensile strength for support and enough elasticity to move...

Connective Tissue Fibers and Ground Substance
10.7K
One of the significant functions of connective tissue is connecting tissues and organs. Unlike epithelial tissue that is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. The matrix usually includes a large amount of extracellular material produced by the connective tissue cells that are embedded within it. It plays a significant role in the functioning of this tissue. The major component of the matrix is a...
