Participation of selected soluble cell adhesion molecules and syndecans in formation and development of endometriosis.

OBJECTIVES

Concentrations of soluble ICAM-2, -3, -4 and syndecan-1 and -4 have not yet been marked in the peritoneal fluid of women with endometriosis. The aim of the study was to determine whether these molecules can participate in formation and development of endometriosis.

MATERIAL AND METHODS

The study comprised of 80 women at the proliferative phase of the menstrual cycle, aged 21 to 49 years (mean age 31. 3 ± 6. 7 years) undergoing laparoscopy, to determine the causes of primary infertility and to confirm or exclude endometriosis. The study group consisted of 60 women with endometriosis in the pelvis as confirmed by laparoscopy and histopathology. The reference group consisted of 20 women in whom no endometriosis. Concentrations of selected sICAM and syndecans in the peritoneal fluid were determined with the use of ELISA method.

RESULTS

Decreased concentrations of sICAM-2 and increased concentrations of sICAM-3, sICAM-4 and syndnecan-1 and -4 were observed in the peritoneal fluid of women with endometriosis and compared with concentrations of this parameter in the reference group (p < 0.0001). Additionally, negative correlation was found between the concentrations of sICAM-3 and sICAM-2 among women with endometriosis. There was no statistically significant correlation between the concentration of sICAM-2 and sICAM-4, sICAM-3 and sICAM-4 and syndecan-1 and syndecan-4 in the examined women.

CONCLUSIONS

Changes in concentrations of all the evaluated molecules were observed in the peritoneal fluid in women suffering from endometriosis. Since they have a role in regulation of the immune response, in angiogenesis and apoptosis of the endometrial cells.
