概括
在西班牙住院的Listeria monocytogenes (LM) 患者中,免疫抑制 (IS) 的患病率从2000年至2021年显著增加. 这种IS的增加与较高的LM感染死亡率有关,强调需要改进预防和管理策略.
科学领域:
- 传染性疾病 传染性疾病
- 流行病学 流行病学
- 免疫学 免疫学 免疫学
背景情况:
- 免疫抑制 (IS) 显著增加了由Listeria monocytogenes (LM) 感染引起的严重疾病的风险.
- 了解LM患者中IS的流行病学趋势对于公共卫生至关重要.
- 该研究的重点是西班牙国家医院出院登记册,以获得全面的数据.
研究的目的:
- 检查西班牙住院患有Listeria monocytogenes (LM) 感染的患者免疫抑制 (IS) 的流行病学.
- 分析IS患病率的趋势及其对2000年至2021年间LM相关死亡率的影响.
- 为了确定与LM患者死亡率增加相关的特定免疫抑制条件.
主要方法:
- 追溯分析了西班牙8152例因LM入院的病例 (2000-2021年).
- IS是由包括肝病,糖尿病,慢性病和各种瘤在内的疾病定义的.
- 统计分析以确定IS患病率和相关死亡率的趋势.
主要成果:
- 48%的LM住院治疗涉及免疫抑制患者,在研究期间,患病率从39.5%上升到60%.
- 糖尿病,固体器官瘤,慢性脏病,血液瘤和肝脏疾病导致IS的增加.
- IS患者的死亡率 (22.4%) 是非IS患者 (11.3%) 的两倍,IS对住院死亡的贡献显著增加.
结论:
- 在西班牙住院的LM患者中,免疫抑制的患病率在过去二十年中显著增加.
- 这种上升的IS患病率与不成比例地对LM相关的死亡率产生更大的影响有关.
- 研究结果强调,迫切需要加强免疫抑制个体中LM感染的预防和管理策略.

Immunodeficiency Diseases
890
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.

Pulmonary Tuberculosis I
215
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
130
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Tumor Immunotherapy
461
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Factors Affecting the Risk of Infection
10.7K
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...
