概括
与慢性乙肝 (CHB) 患者相比,慢性乙肝 (CHD) 患者的非疾病特异性抗体 (NOSA) 标位和免疫球蛋白G (IgG) 水平较高. 在心血管疾病中,这些升高的水平与疾病严重程度相关,但其临床相关性不清楚.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 免疫学 免疫学 免疫学
- 病毒学 病毒学
背景情况:
- 肝炎病毒感染引发免疫反应.
- 肝炎D病毒 (HDV) 导致严重的病毒性肝炎.
- 在慢性肝炎D (CHD) 中,关于非疾病特异性抗体 (NOSA) 标位和免疫球蛋白G (IgG) 的数据有限.
研究的目的:
- 调查慢性肝炎D患者的NOSA标位和IgG水平.
- 为了比较这些慢性肝炎,慢性乙型肝炎 (CHB) 和自身免疫性肝炎 (AIH) 患者之间的免疫标志物.
- 探索免疫标志物和心脏病的疾病参数之间的相关性.
主要方法:
- 对40名心脏病患者,70名心脏病患者和46名AIH患者的NOSA标位和IgG水平的比较分析.
- 在CHD患者中评估先前的基化干扰素-α (IFN-α) 治疗.
- 对IgG水平与HDV病毒载量,转氨酶和肝硬度的相关性分析.
主要成果:
- 增加的NOSA标位在CHD患者 (69%) 显著高于CHB患者 (43%) (p<0.01).
- 中位数IgG水平在CHD患者 (16.9g/L) 显著高于CHB患者 (12.7g/L) (p<0.01),AIH患者显示最高水平 (96%,19.5g/L).
- 在心血管疾病中,IgG水平与较高的HDV病毒载荷,转氨酶和肝硬度相关;根据先前的IFN-α治疗,没有观察到差异.
结论:
- 与CHB患者相比,慢性肝炎D患者经常表现出较高的NOSA标位和IgG水平.
- 在心血管疾病中观察到的自身抗体在很大程度上是不特定的,它们的临床意义仍然不清楚.
- 冠状动脉疾病中的免疫标志物概况虽然与冠状动脉疾病不同,但在之前的IFN-α治疗中并没有显著改变.

Gastritis-II: Pathophysiology
380
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Chronic Pancreatitis I: Introduction
116
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Antigens Involved in Adaptive Immunity
560
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Immune Response Against Viral Pathogens
829
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Autoimmune Disorders
517
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.
