孤立肌炎揭示全身性红斑狼:一种罕见的初始表现
在PubMed上查看摘要
概括
此摘要是机器生成的。系统性红斑狼 (SLE) 很少仅表现为肌肉炎,导致肌肉衰弱. 早期诊断和治疗与狼相关的肌肉炎对于改善患者的结果至关重要.
科学领域
- 关节病学
- 免疫学
- 神经学
背景情况
- 系统性红斑狼 (SLE) 是一种复杂的自身免疫性疾病,临床表现不同.
- 肌肉骨症状在SLE中很常见,但由于最初的表现是罕见的,因此可能会延迟诊断.
研究的目的
- 报告一种罕见的SLE病例,最初呈现出孤立的自身免疫肌炎.
- 强调在炎症性肌肉病的差分诊断中考虑SLE的重要性.
主要方法
- 一个19岁的女性, 肌肉逐渐衰弱.
- 诊断包括血清肌酸酶,抗核抗体,肌电图和肌肉活检.
- 自免疫检测证实抗dsDNA和抗Sm抗体,符合2019年EULAR/ACRSLE标准.
主要成果
- 患者表现出孤立的近端肌肉衰弱,肌酸激酶升高和阳性抗核抗体.
- 肌肉活检证实了自身免疫性肌肉炎, 进一步的测试显示了SLE特异性抗体.
- 确立了主导性肌肉炎的SLE诊断.
结论
- 孤立的肌肉炎可能是系统性红斑狼 (SLE) 的首要表现.
- 早期识别和治疗狼相关的肌肉炎,使用皮质类固醇和氧化,导致显著的临床改善.
- 这一案例强调了需要将SLE纳入炎症性肌肉病的差异诊断,特别是在近端肌肉衰弱的年轻女性中.

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...
Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...
Myocarditis is an inflammatory condition of the myocardium requiring meticulous nursing management for optimal patient outcomes. Effective management begins with a thorough assessment of the patient's medical history, paying close attention to past infections, autoimmune disorders, travel history, and exposure to toxins or drugs. Recent viral infections and systemic diseases are particularly relevant due to their potential role in triggering myocarditis.Physical Examination and MonitoringThe...
