- 免疫学 免疫学 免疫学
- 传染性疾病 传染性疾病
背景情况:
- 系统性红斑狼 (SLE) 涉及免疫功能障碍和感染易感性增加.
- 与感染相关的发作 (IAF) 在SLE中很常见,但其临床特征尚不清楚.
- 了解IAF至关重要,因为它们可能会影响疾病管理和患者的治疗结果.
研究的目的:
- 调查SLE中IAFs的临床表型和免疫特征.
- 为了比较IAF与其他火焰 (OF) 的严重程度和长期损害.
- 探索潜在的独特的病理生理机制,是IAF的基础.
主要方法:
- 对2039名患者访问的查,以确定134个发作 (狼丧失低疾病活动状态 - LLDAS).

01:26Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
