概括
减肥手术可以改善体重和代谢健康,但免疫细胞细胞因子的产生仍然有所改变. 即使体重正常化后,与体重正常的人相比,前肥胖患者的炎症反应也受到干扰.
科学领域:
- 免疫学 免疫学 免疫学
- 代谢手术 代谢手术
- 肥胖医学 肥胖医学
背景情况:
- 减肥手术对于严重的肥胖是有效的,经常使体重和代谢标志物正常化.
- 然而,它对全身炎症媒介和白细胞功能正常化后的影响尚未完全理解.
研究的目的:
- 研究肥胖的手术治疗对由脂多糖糖 (LPS) 刺激的白细胞产生的细胞因子产生的影响.
- 为了比较正常体重个体,肥胖者,肥胖糖尿病患者和腹部外科手术后患者的免疫反应.
主要方法:
- 横截面研究设计. 截面研究设计.
- 用LPS刺激的白细胞中细胞因子生产动学的分析.
- 在正常体重 (NW),肥胖 (Ob),糖尿病肥胖 (Ob-DM) 和以前肥胖的绕道手术后 (fOb+bypass) 组之间进行比较.
主要成果:
- 与NW相比,Ob和fOb+绕道组的IL-6水平在Ob和fOb+绕道组中更高.
- 在NW个体中,自发IL-10分泌量更高.
- 除了NW之外,LPS刺激在所有组都增加了IL-10; fOb+绕道中的IL-18和IL-33分泌模式与Ob组相似.
结论:
- 肥胖手术不能完全恢复白细胞中正常的细胞因子生产动态.
- 在手术后,尽管体重恢复,但在以前肥胖的患者中,炎症和抗炎性细胞因子配置仍然受到干扰.

Chronic Inflammation: Introduction
50
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...

Inflammatory Bowel Disease III: Crohn's Disease
69
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

Acute Pancreatitis II: Pathophysiology
49
The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...

Chronic Pancreatitis II: Pathophysiology
35
Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...
