概括
爪视频毛囊镜 (NVC) 异常预测系统性硬化症 (SSc) 中肺功能恶化和间歇性肺病 (ILD) 进展. 这些发现支持NVC作为一种非侵入性工具,用于识别需要更密切监测和早期治疗的SSc-ILD患者.
科学领域:
- 类风湿病学 类风湿病学
- 肺部病理学 肺部病理学
- 微血管医学是一种微血管医学.
背景情况:
- 系统性硬化症 (SSc) 是一种连接组织疾病,其中间歇性肺病 (ILD) 是死亡的主要原因.
- 爪视频毛囊显微镜 (NVC) 评估SSc中的微血管损伤,但其对ILD进展的预测价值尚未得到充分确立.
- 克雷布斯登肺-6 (KL-6) 是一种潜在的ILD生物标志物,但它与NVC模式和肺功能下降的相关性需要进一步研究.
研究的目的:
- 调查SSc患者的基线NVC异常是否预测肺功能下降,ILD进展以及两年内血清生物标志物的变化.
- 探索NVC模式,KL-6水平和疾病活动指数之间的关系.
主要方法:
- 一项前性纵向研究包括SSc患者 (n=74),评估ILD的存在和严重程度.
- 基线评估包括NVC,高分辨率计算机断层扫描 (HRCT),肺功能测试 (PFT) 和血清生物标志物分析 (KL-6,IL-18,IL-18BP).
- 通过强迫生命能力 (FVC) 的变化,一氧化碳的扩散能力 (DLCO) 和使用多变量回归分析的HRCT发现来监测ILD进展.
主要成果:
- 在NVC上的毛细血管失调预测了%FVC和%DLCO的更大下降,以及皮肤分数 (mRSS) 的恶化.
- 晚期的NVC模式与恶化的mRSS相关,增加了KL-6水平,并降低了%DLCO.
- 较高的基线SCTC-DI得分预测了HRCT上的渐进性纤维化和两年后升高的CRP水平.
结论:
- 基线NVC异常,特别是毛细血管失调和晚期模式,是SSc.中ILD进展和肺功能下降的独立预测因素.
- 升高的KL-6水平与NVC异常和肺功能下降相关.
- 在SSc中,NVC显示出作为ILD风险分层的非侵入性工具的潜力,有助于早期干预和改善患者的治疗结果.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
38
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Nephrotic Syndrome II : Assessment and Medical Management
24
IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document...
