NCT05455151

Brief Summary

The investigation is devoted to the study of the effect of the introduction of autologous platelet-rich plasma (PRP) on the thickness of the endometrium. It was found that the injection of PRP and endometrial cells resuspended in PRP into the endometrium of patients with thin endometrium leads to an increase in the proliferation of endometrial cells, and as a result, to an increase in its thickness.

Outcome Measures

Primary Outcomes (5)

  • Change in endometrial thickness after treatment compared with control.

    Ultrasonography measurements of endometrial thickness before and after the therapy and compare the thickness. Endometrial thickness measured in mm.

    Baseline and 2 month

  • The Doppler-assisted detection of the uterine spiral arteries

    The number of identified vessels is counted and the percentage of detection frequency is calculated accordingly, adjusted for the McNemar's binomial test. Compare the rates of visualization of the uterine spiral arteries after therapy in all groups of patients.

    1 month

  • Study of the effect of therapy on the onset of pregnancy

    Investigation of the rates of clinical pregnancies and live births in all groups. After therapy, the number of clinical pregnancy and the number of live births were calculated.

    9 months

  • The content of growth factor in autologous PRP

    Investigation of the content of platelet-derived growth factor-BB (PDGF-BB) and vascular endothelial growth factor (VEGF) in autologous PRP. Relative levels of PDGF-BB and VEGF are normalized to the total protein content.

    3 month

  • Phenotyping of cells isolated from endometrial biopsies

    Investigation of cellular composition in endometrial biopsy. The percentage of cells positive for markers of mesenzymal stromal cells, epithelial and endothelial cells, lymphocytes is calculated and the determination of the phenotype of cells in endometrial biopsy.

    3 month

Study Arms (4)

Conservative therapy

ACTIVE COMPARATOR

This is Group 1, whose patients received electrical impulse therapy using a BTL-4000 Premium G device (BTL Medical Technologies, Czech Republic) starting from day 5-7 of menstrual cycle for 10-12 days daily.

Procedure: Conservative therapy

PRP injection

EXPERIMENTAL

This is Group 2, whose patients received single intraendometrial injections of autologous PRP during proliferative phase (day 6-9) of menstrual cycle.

Biological: PRP injection

Injection of PRP after conservative therapy

EXPERIMENTAL

This is Group 3, whose patients received electrical impulse therapy identically with Group 1 during the first menstrual cycle. In the second cycle, the patients received autologous PRP injections identically with Group 2.

Biological: Injection of PRP after conservative therapy

Injection of PRP with endometrial cells

EXPERIMENTAL

This is Group 4, whose patients received single intraendometrial injections of the minimally manipulated autologous endometrial cells suspended in autologous PRP during proliferative phase (day 6-9) of menstrual cycle.

Biological: Injection of PRP with endometrial cells

Interventions

Conservative therapy to which the patients were subjected was the effect of an electrical impulse

Conservative therapy
PRP injectionBIOLOGICAL

This intervention consisted of injecting platelet-rich plasma (PRP) into the endometrium

PRP injection

This intervention consisted of conducting conservative therapy with an electrical impulse and then injecting PRP inside the endometrium

Injection of PRP after conservative therapy

This intervention consisted of injecting endometrial cells suspended in prp

Model Details: The patients were divided into 4 groups depending on the substances introduced into the basal layer of the endometrium. Group 1 underwent conservative therapy. Group 2 received intraendometrial injections of autologous PRP instead of the conservative therapy. Group 3 received identical injections after conservative therapy. Group 4 received injections of the minimally manipulated autologous endometrial cells suspended in autologous PRP.
