Neglected Tropical Diseases (NTDs), particularly those caused by parasites, remain a major Public Health problem in tropical and subtropical regions, with 10% of the world population being infected. Their management and control have been traditionally hampered, among other factors, by the difficulty to deploy rapid, specific, and affordable diagnostic tools in low resource settings. This is especially true for complex PCR-based methods. Isothermal nucleic acid amplification techniques, particularly loop-mediated isothermal amplification (LAMP), appeared in the early 21st century as an alternative to PCR, allowing for a much more affordable molecular diagnostic. Here, we present the status of LAMP assays development in parasite-caused NTDs. We address the progress made in different research applications of the technique: xenomonitoring, epidemiological studies, work in animal models and clinical application both for diagnosis and evaluation of treatment success. Finally, we try to shed a light on the improvements needed to achieve a true point-of-care test and the future perspectives in this field.
被忽视的热带病(NTDs),尤其是由寄生虫引起的那些疾病,仍然是热带和亚热带地区的一个主要公共卫生问题,全球10%的人口受到感染。传统上,其管理和控制受到诸多因素的阻碍,其中包括在资源匮乏地区难以部署快速、特异且经济实惠的诊断工具。基于复杂PCR的方法尤其如此。等温核酸扩增技术,特别是环介导等温扩增(LAMP),在21世纪初作为PCR的替代方法出现,使得分子诊断的成本大幅降低。在此,我们介绍了LAMP检测方法在由寄生虫引起的被忽视热带病中的发展现状。我们阐述了该技术在不同研究应用中取得的进展:异体监测、流行病学研究、动物模型研究以及用于诊断和评估治疗效果的临床应用。最后,我们试图阐明实现真正的即时检测所需的改进以及该领域的未来前景。
