Analysis of changes in the levels of soluble molecules CD50, CD54 and CD95 in the blood serum of patients with uterine fibroids depending on the characteristics of the disease (pilot study)

Background. Currently, the search for circulating immunological and inflammatory markers that play a significant role in the pathogenesis of uterine fibroids (UF) is relevant.Aim. Changes in the serum levels of soluble molecules CD50 (sCD50), CD54 (sCD54) and CD95 (sCD95) in patients with UF depending on the characteristics of the disease.Materials and methods. The study involved 78 patients with UF aged 31–59 years and 45 clinically healthy women of comparable age. The patients were divided into the following groups depending on the localization of the myomatous node: interstitial-subserous localization (n = 17), subserous localization (n = 16), submucosal localization (n = 15), interstitial-submucosal localization (n = 15), interstitial localization (n = 15). In 34.6 % patients, the number of myoma nodes was 4–6, in 46.2 % women there were 2–3 nodes, in 19.2 % – 1 node.Determination of the serum concentration of sCD50, sCD54 and sCD95 molecules was performed using a two-site enzyme immunoassay and expressed in conventional units (U / ml).Results. The average serum concentration of sCD95, sCD54 and sCD50 in all patients with UF was significantly higher than in the control group (p 0.05). The maximum level of the tested molecules was found in UF patients with submucosal localization and the presence of one myomatous node.Conclusions. The detected increase in sCD50, sCD54 and sCD95 levels in UF patients indicates the participation of these proteins in the immunopathogenesis of this pathology. The imbalance in studied proteins levels is most pronounced in submucosal localization of fibroids, which may indicate an unfavorable course of the disease and serve as an additional criterion for selecting patients in the preoperative period.
