概括
青少年发病的混合结合组织疾病 (jMCTD) 与成人发病的MCTD具有相同的临床特征,但手指胀较少. 尽管需要更密集的治疗,但jMCTD患者表现出更有利的结果,缓解率更高.
科学领域:
- 类风湿病学 类风湿病学
- 儿科风湿病学 儿科风湿病学
- 免疫学 免疫学 免疫学
背景情况:
- 青少年发病的混合结合组织疾病 (jMCTD) 是混合结合组织疾病 (MCTD) 的罕见子群,占7-23%的病例.
- 关于jMCTD的特定临床特征,治疗策略和长期结果的数据有限.
- 了解jMCTD对于优化患者护理和管理至关重要.
研究的目的:
- 综合描述诊断为jMCTD的患者的临床特征,治疗方法和结果.
- 为了将这些特征,治疗方法和结果与成人发病性MCTD (aMCTD) 患者的特征,治疗方法和结果进行比较.
- 确定青少年和成人形式的MCTD之间的差异和相似之处.
主要方法:
- 一个多中心,回顾性,病例控制研究使用法国MCTD队列进行.
- 确定了47名jMCTD患者,并与3名aMCTD患者进行了匹配以进行比较.
- 收集和分析了临床表现,诊断标准 (夏普和卡苏卡瓦),治疗方法和患者结局的数据.
主要成果:
- 与aMCTD患者相比,jMCTD患者 (93.6%为女性,中位数发病年龄为14岁) 主要呈现雷诺现象,关节痛和肌痛,并且与aMCTD患者相比,手指发胀的频率较低 (p < 0.0001).
- 治疗通常涉及葡萄糖皮质激素,氧化和免疫抑制剂,jMCTD患者接受更高的初始葡萄糖皮质激素剂量和更频繁的甲基和修复药.
- 随访时间中位数为9.8年后,jMCTD患者的缓解率较高 (61.7%与44.0%,p <0.05),但与aMCTD患者相比,其他CTD的进展率和间歇性肺病的发展率相似.
结论:
- jMCTD与aMCTD具有共同的核心临床特征,其中一个显著的区别在于指部发胀的发病率降低.
- 对jMCTD的结果似乎比对aMCTD的结果更有利,其特点是显著更高的缓解率.
- 为了在jMCTD中获得这些改善的结果,需要更密集的治疗干预措施,包括更高剂量的葡萄皮质类药物和特定的免疫抑制剂,如甲基和利图西马布.

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
443
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

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...

Classification of Connective Tissues
14.5K
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....

Autoimmune Disorders
1.4K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Myocarditis II: Clinical Features and Diagnostic Tests
236
Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Secondary Lymphoid Organs
8.7K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
