概括
在东非和东南亚,后卡拉阿扎尔皮肤雷什曼病 (PKDL) 的危险因素不同. 了解这些因素,包括宿主,寄生虫和环境影响,对于开发对这种被忽视的热带疾病有效的控制策略至关重要.
科学领域:
- 被忽视的热带疾病被忽视的热带疾病
- 莱什曼病的研究研究
- 皮肤病学和免疫学
背景情况:
- 卡拉阿扎尔后皮肤雷什曼病 (PKDL) 在东非 (EA) 和东南亚 (SEAR) 呈现不同.
- 在幼儿中,EA PKDL发生在内脏莱什曼病 (VL) 治疗后不久,而SEAR PKDL影响在VL治疗后的青少年/年轻人.
- 在这两个地区,对PKDL发展的风险因素的了解仍然很少.
研究的目的:
- 审查和综合有关PKDL风险因素,流行病学,遗传学,病理生理学,免疫反应和并发感染的当前知识.
- 确定EA和SEAR之间的PKDL呈现和风险因素的关键差异和相似之处.
- 为未来的PKDL研究和控制策略提供信息.
主要方法:
- 为了收集关于PKDL的数据,进行了全面的文献搜索.
- 提取的信息集中在宿主因素,寄生虫因素,药物药理动力学/药理动力学,环境影响和并发感染.
- 数据综合旨在确定与PKDL相关的模式和重大风险因素.
主要成果:
- 宿主因素:年轻年龄和男性性别是EA的风险因素;在EA和SEAR中观察到PKDL中的IFNGR1表达率下降.
- 寄生虫因素:VL/PKDL菌株的差异和共感染 (例如,勒普托马纳斯西莫里) 有关.
- 其他因素:以前的VL治疗,药物特性,暴露,紫外线和影响免疫反应下降的微生物共感染是显著的.
结论:
- 对PKDL病理生理学的进一步研究对于理解免疫应答调节至关重要.
- 优化VL治疗,可能使用多种药物治疗方案或免疫修饰剂,可以降低PKDL发病率.
- 建议采用综合的PKDL管理方法,考虑并发症和皮肤疾病策略,以有效控制.

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...

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
