概括
患有抗中性粒细胞体抗体 (ANCA) 相关血管炎 (AAV) 的患者面临某些血液癌症和固体瘤的风险增加. 这凸显了对AAV患者个性化癌症查策略的需求.
科学领域:
- 风湿病学和瘤学
- 自身免疫性疾病和癌症流行病学
- 罕见疾病的现实世界证据
背景情况:
- 反中性细胞质抗体 (ANCA) 相关的血管炎 (AAV) 是一种罕见的自身免疫性疾病,导致中小型血管的炎症.
- 以前的假设表明,由于免疫失调和细胞毒性治疗,AAV的恶性瘤风险增加,但缺乏大规模的证据.
- 这项研究解决了对AAV患者癌症风险的现实数据的需求.
研究的目的:
- 在被诊断为AAV的患者中调查和量化血液和固体器官恶性瘤的风险.
- 描述与AAV相关的特定癌症类型.
- 提供证据,为AAV制定量身定制的癌症监测策略.
主要方法:
- 一项回顾性队列研究,使用来自TriNetX研究网络 (2014-2024) 的非识别电子病历数据.
- 确定了19238名患有AAV的患者,倾向性得分与18,255名对照进行了匹配 (1:1).
- 使用Cox比例危险回归来计算危险比率 (HR) 和95%置信区间 (95%CI) 的5年恶性瘤发病率进行了比较.
主要成果:
- 患有AAV的患者的整体癌症风险显著增加 (HR 1.23;95% CI 1.12-1.35).
- 血液性恶性瘤 (HR 2.12;95% CI 1.77-2.53),特别是骨髓质综合征 (HR 4.11) 和白血病 (HR 2.72) 的风险增加.
- 还确定了特定固体瘤的风险增加,包括肺癌 (HR 1.78),膀癌 (HR 1.99),大脑癌 (HR 2.22),嘴唇/口腔/喉癌 (HR 1.78).
结论:
- AAV患者面临某些血液和固体器官癌症的明显和高风险.
- 这些发现强调了为患有AAV的个体制定专门的癌症监测协议的必要性.
- 该研究提供了实质性的现实世界证据,以指导恶性瘤风险分层和AAV人群的积极查.

Nephrotic Syndrome I : Introduction
470
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Nephrotic Syndrome II : Assessment and Medical Management
184
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...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
