概括
系统性免疫炎症指数 (SII) 和系统性炎症反应指数 (SIRI) 是有前途的,可作为预测自身免疫甲状腺炎 (AT) 死亡率的具有成本效益的生物标志物. 这些指数提供了对免疫失调的洞察力,并可以帮助AT患者的风险分层.
科学领域:
- 免疫学 免疫学 免疫学
- 内分泌学 在内分泌学.
- 生物统计学 生物统计学
背景情况:
- 慢性炎症是自身免疫性甲状腺炎 (AT) 的核心,但目前的生物标志物不能预测系统性并发症.
- 系统性免疫炎症指数 (SII) 和系统性炎症反应指数 (SIRI) 等新型指数可能为AT死亡率提供预后价值.
研究的目的:
- 调查SII和SIRI与自身免疫性甲状腺炎患者全因死亡率之间的关联.
- 确定这些炎症指数的潜在值,这些指标表明死亡风险增加.
主要方法:
- 来自NHANES 2007-2012的1053名AT患者的分析,从完整血清数据计算SII和SIRI.
- 考克斯的比例危险模型和受限立方线被用来评估死亡风险和非线性关系.
- 死亡率数据是通过与国家死亡指数联系而获得的.
主要成果:
- 升高的SII和SIRI与AT患者全因死亡率的增加显著相关.
- 在完全调整后,增加的SII (HR=1.819) 和SIRI (HR=1.314) 独立预测了更高的死亡率.
- 确定了关键值: ln-SII ≥6.18 (HR=2.629) 和 SIRI ≥1.01 (HR=1.257) 显示死亡风险急剧升级.
结论:
- SII和SIRI是可靠,具有成本效益的生物标志物,用于预测AT的死亡率.
- 对SII和SIRI的定义值表明向病理性炎症和死亡风险增加的转变.

Synthesis and Regulation of Thyroid Hormones
7.0K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

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
229
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...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
511
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
