AbstractImmunosuppression permits graft survival after transplantation and consequently a longer and better life. On the other hand, it increases the risk of infection, for instance with cytomegalovirus (CMV). However, the various available immunosuppressive therapies differ in this regard. One of the first clinical trials using de novo everolimus after kidney transplantation [1] already revealed a considerably lower incidence of CMV infection in the everolimus arms than in the mycophenolate mofetil (MMF) arm. This result was repeatedly confirmed in later studies [2–4]. Everolimus is now considered a substance with antiviral properties. This article is based on the expert meeting “Posttransplant CMV infection and the role of immunosuppression”. The expert panel called for a paradigm shift: In a CMV prevention strategy the targeted selection of the immunosuppressive therapy is also a key element. For patients with elevated risk of CMV, mTOR inhibitor-based immunosuppression is advantageous as it is associated with a significantly lower incidence of CMV events.

The objective: determination of morphofunctional features of leiomatous nodes and endometrium in women with uterine leiomyoma and infertility to restore reproductive function and prevent recurrence of the underlying disease. Materials and methods. In order to restore reproductive function and prevent recurrence of the underlying disease, morphofunctional features of leiomatous nodes and endometrium in women with uterine leiomyoma and infertility were determined. Thirty samples of leiomyomatous nodes and endometrium were examined, among which 15 were obtained from women with multiple uterine leiomyoma and infertility and 15 samples from women with uterine leiomyoma with isolated uterine leiomyoma. During the study, a general-histological method was used for staining with hematoxylin-eosin and picrofuxin by van Gizon, as well as immunohistochemical methods. Histological examination of the endometrium was performed according to conventional protocol, taking into account the day of the menstrual cycle and R.W. Noyes criteria. Results. In the morphological examination of leiomyomatous nodes in the vast majority of cases the presence of uterine leiomyomas of simple and cell types or their combination was established. In women with multiple uterine leiomyoma, simple-type leiomyoma (53.3%) was predominant, and in patients with isolated leiomyoma the signs of cellular uterine leiomyoma (66.7%) were more frequently found. In 80.0% of women with uterine leiomyoma revealed pathology of the endometrium, such as glandular and glandular-fibrous polyps, simple and complex atypical endometrial hyperplasia, which confirms the theory about the only pathogenetic mechanisms of the emergence of hyperplastic processes of female organs. In 66.7% of women with multiple leiomyomas, signs of chronic endometritis have been found, which exacerbates the pathological process and can have a negative impact on the reproductive function, such as secretory endometrial transformation and impaired blastocyst implantation, and explains a much higher percentage of infertility in the group. Conclusion. In women with impaired reproductive function, patients with uterine leiomyoma, it is necessary to conduct a study of the receptivity of the reproductive organs, namely - the endometrium and leiomatous nodes. This will make it possible to use one or another method of treatment in order to restore reproductive function and prevent recurrence of the underlying disease. Keywords: infertility, uterine leiomyoma, endometrium, receptive apparatus.
