  • Description: Introduction. The article is devoted to the study of the mechanism of occurrence of postcovid syndrome, a new laboratory method for its diagnosis and issues of drug and non-drug rehabilitation of patients who have suffered COVID-19. The purpose of this work was to study the possibilities of using the method of monochrome analysis of nanoparticles for instrumental and laboratory diagnostics of postcovid syndrome and to substantiate the use of complex therapeutic approaches to the treatment of patients. Materials and methods . The biomaterial (saliva) of 250 patients who underwent COVID-19 in mild, moderate and severe forms, with a slight predominance of males, in the age range from 18 to 75 years, who were in the Center of Eastern and European Medicine (Moscow) on rehabilitation treatment in the period from June 2020 to September 2021, was studied by the method of monochrome analysis of nanoparticles. According to the results of the work carried out, it was found that the most typical saliva spectrum of patients diagnosed with “postcovid syndrome” was multimodal (three or more peaks) with the greatest contribution (45%) to light scattering on agglomerates of  nanoparticles with a  diameter of  more than 1000  nm, with detectable nanoparticles of the middle sub-range of the spectrum from 119 to 122 nm with a 15% contribution to light scattering and an increased contribution to light scattering up to 41% on small nanoparticles with a diameter of 22 nm. Results . Analysis of the results of the study showed a statistically significant (p < 0.01) appearance of a peak of 119 nm on the histogram of patients, which was not observed either in the group of practically healthy individuals (control group) or in the group of patients with general somatic pathology (comparison group). Conclusions. An algorithm for non-invasive diagnosis of postcovid syndrome by saliva was developed. Also, special attention was paid during the study to the development of an integrated approach to the rehabilitation of patients who have undergone a new coronavirus infection, including medicinal and non-medicinal methods of treatment. >< 0.01) appearance of a peak of 119 nm on the histogram of patients, which was not observed either in the group of practically healthy individuals (control group) or in the group of patients with general somatic pathology (comparison group).
