uCTD and HT and especially their concurrence are commonly a concomitant disease and risk factors for infertility in women due to impaired endometrial receptivity. In uCTD, connective tissue remodeling processes are substantially retarded, which ultimately leads to increased processes of endometrial stromal sclerosis, reduced endometrial receptivity, and infertility. The most pronounced morphological and immunophenotypical changes have been ascertained to develop in the uCTD + NT group. The findings may be used to predict and devise new infertility treatments in patients with uCTD + NT.
Currently, the problems of the mechanisms of immune and inflammatory response aging, which determine the mechanisms of the development of the inflammatory process in the elderly, are being actively studied. A sectional observation of senile tuberculosis in a patient K., 78 years old, who had been treated for 4 months in the University Clinical Hospital No. 4 of the First Sechenov Moscow State Medical University in 2018 is presented. After autopsy, histological, histochemical and PCR examination, the following pathoanatomical diagnosis was made: primary (senile) tuberculosis with hematogenous and lympho-vascular generalization, with a focus of caseous pneumonia in the III segment of the right lung; caseous lymphadenitis of bifurcation, thoracic and abdominal paraaortic lymph nodes; miliary and large-focal generalization in the lungs, parietal and visceral pleura on the left, spleen and liver (acid fast stain; PCR study No. 18-5935 dated 08/13/2018 (Central Research Institute of Tuberculosis) detected DNA of mycobacterium tuberculosis complex). A feature of senile tuberculosis is the course of primary tuberculosis with hematogenic generalization and predominantly exudative-necrotic tissue reaction. Its pathogenesis is mainly due to the phenomenon of "aging immune system" (immunosenescence), as well as inflammaging — features of the inflammatory response in old age. Their main characteristics are the preactivated status of the immune system even before the recognition of the antigen, characterized by a basal level of circulating cytokines, as well as a sharp weakening of the adaptive immune response in the presence of an antigen associated with impaired functioning of the immune system with a large number of memory T cells lacking naive T-cells.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
