Хромато-масс-спектрометрическое исследование микробных жирных кислот в биологических жидкостях человека и их клиническая значимость

Abstract

The technique of mass-spectrometric microbial markers is known for almost 20 years. The technique is described in a number of research publications, dissertations and methodological literature. It passed the registration in Roszdravnadzor and is permitted for implementation as a new medical technology in medical institutions on the territory of the Russian Federation ("The evaluation of microecological human status using technique of mass-spectrometry" license FS № 2010/038 of 24.02.2010). The technique of mass-spectrometric microbial markers began to be developed as instrument of clinical routine analysis and monitoring of microecological status, infection and disbiosises in clinical and out-patient practice. The description of technology of massspectrometric microbial markers in this aspect requires different than before approach to introduction of clinical laboratory assistants and physicians into technique application. The substantiation given concerning species specificity of composition of fatty acids and (fatty) aldehydes of cellular wall of microorganisms as a basis of their species differentiation in pure culture. The choice is explained concerning molecular markers for their detection in blood and other clinical material with the purpose of further reconstruction of composition of human microbial cenosis (microecology) on blood or calculation of composition of mixed infection in organs om samples of inflammation focus urine, liquor, phlegm, exudate, drainage, and similar samples containing chemical information about microbes.

Метод масс-спектрометрии микробных маркеров (МСММ) известен 20 лет. Он описан в ряде научных публикаций, диссертациях и методической литературе, прошел регистрацию в Росздравнадзоре и разрешен к применению в качестве новой медицинской технологии в медицинских учреждениях на территории Российской Федерации (“Оценка микроэкологического статуса человека методом хромато-масс-спектрометрии", разрешение ФС № 2010/038 от 24.02.10). Метод МСММ только начал формироваться как инструмент клинического рутинного анализа и мониторинга микроэкологического статуса, инфекции и дисбиозов в клинической и амбулаторной практике. Описание технологии МСММ в таком аспекте требует иного, чем было сделано ранее, подхода к введению клинических лаборантов и врачей в метод. Подробно дается обоснование видовой специфичности состава жирных кислот и (жирных) альдегидов клеточной стенки микроорганизмов как основы их видовой дифференциации в чистой культуре. Объясняется выбор молекулярных маркеров для их детектирования в крови и другом клиническом материале с целью дальнейшей реконструкции состава микробного сообщества (микроэкологии) человека по крови или расчет состава микст-инфекции в органах по материалу из очага воспаления моче, ликвору, мокроте, экссудату, дренажу и аналогичным пробам, содержащим химическую информацию о микробах.
