概括
狼性炎 (LN) 爆发期间血清干扰素 (IFN) -α水平升高预测脏结果更差. 在LN患者中,较高的IFN-α水平与更频繁的爆发和更快的功能下降有关.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學.
- 免疫学 免疫学 免疫学
- 生物标志物发现发现
背景情况:
- 狼性炎 (LN) 是系统性红斑狼的一种严重并发症.
- 对LN进展的预测生物标志物对于及时干预至关重要.
研究的目的:
- 研究LN爆发的患者血清干扰素 (IFN) -α水平和结局之间的关联.
- 确定基线IFN-α水平是否可以预测LN病的严重程度和进展.
主要方法:
- 研究了一组92名患有活跃LN和初始估计的淋巴球过率 (eGFR) ≥60毫升/分钟的患者.
- 使用Simoa测量了血清IFN-α水平.
- 脏结局包括随后的LN爆发的时间,持续的eGFR下降 (30%和50%),进展到末期脏疾病 (ESRD),以及脏不良事件.
主要成果:
- 在LN爆发时血清IFN-α水平升高与较差的结局显著相关.
- 较高的IFN-α基线水平增加了≥2次后续LN爆发的风险 (HR: 1.31),30%的eGFR下降 (HR: 1.27),50%的eGFR下降 (HR: 1.27) 和ESRD进展 (HR: 1.29).
- 确定IFN-α切断值为0.6pg/mL用于预测脏不良事件.
结论:
- 血清IFN-α是一种潜在的预测生物标志物,用于狼性炎的不良结局.
- 在LN爆发时IFN-α水平升高表明疾病复发的风险更高,功能明显恶化.

01:17Factors Affecting Renal Clearance: Renal Impairment
54
Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

01:11Renal Failure: Dose Adjustments
64
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
