    Vascular Endothelial Growth Factor Serum Levels in Women with Advanced Endometriosis

    Acta Endo (Buc) 2016 12(1): 7-13 doi: 10.4183/aeb.2016.7

    Context. Endometriosis is a common gynecological disease, characterized by ectopic deposits of endometrial tissue outside of the uterine cavity, and it is associated with pelvic pain and infertility, with an important impact on the quality of life. At this point there is a controversy regarding the etiology and pathophysiology of endometriosis and it seems that pro-angiogenic growth factors might be involved, but their role is not completely understood. Objective. To evaluate the serum concentration of the main growth factors in patients with diagnosed endometriosis compared to healthy controls. S ubjects and Methods. A total of 157 women were divided into two study groups (Group I – endometriosis; Group 2 – healthy women). Serum levels of VEGF, G-CSF, GM-CSF, b-FGF, EGF, and HGF were measured with Human Multiplex Cytokine Panels. Results. VEGF serum levels were significantly lower in women with endometriosis compared to controls (1.924±0.145 compared to 1.806±0.078 pg/mL, p<0.001). Serum levels of GM-CSF, b-FGF, EGF, and HGF respectively did not differ significantly between patients with endometriosis and healthy controls. G-CSF had a very low detection rate. Conclusions. The present study showed that VEGF serum levels are significantly lower in endometriosis patients compared to healthy controls, indicating a possible role in endometriosis pathogenesis.

    Interleukin-8 and vasomotor symptoms in natural and surgically induced menopause

    Acta Endo (Buc) 2013 9(1): 133-144 doi: 10.4183/aeb.2013.133

    Objectives. The aim of this study was to evaluate serum levels of interleukin (IL)-8 in pre- and postmenopausal women and in patients with surgically-induced menopause, and the relationship between IL-8 and vasomotor symptoms. Material and Method. 175 women were enrolled and were divided into 5 groups (I – Fertile women; II – Pre- and perimenopausal women; III – Postmenopausal women; IV – Surgically-induced menopause; V – Chronic inflammation). Multiplex cytokine kits were used to evaluate serum levels of interleukin-8. We determined the serum levels of the follicle stimulating hormone, of the luteinizing hormone, 17β-estradiol, progesterone, dehydroepiandrosterone and dehydroepiandrosterone sulfate using sandwich ELISA. The severity of the vasomotor symptoms was evaluated according to FDA guidelines. Results. Serum concentration of IL-8 in women with natural menopause (233.0±226.5 pg/ml; p<0.001) and in women with surgically-induced menopause (148.0±162.0 pg/ml; p=0.045) is significantly higher than in women of reproductive age (84.88±82.32 pg/ml). Serum levels of IL-8 in premenopausal women, postmenopausal women, and in women with surgically-induced menopause, respectively, with severe and moderate hot flashes, on one hand (174.8±90.94 pg/ml, 369.3±194.2 pg/ml, respectively 274.1±146.3 pg/ml), is significantly higher than in women without vasomotor symptoms or with mild hot flashes, on the other hand (19.97±22.15 pg/ml, 28.66±35.72 pg/ml, respectively 28.94±37.68 pg/ml; p<0.001). Serum levels of IL-8 are significantly higher in women of reproductive age with chronic inflammatory pathology (152.3±121.0 pg/ml) than in women without such pathology (84.88±82.32 pg/ml; p=0.02). Conclusions. IL-8 is significantly higher in postmenopausal women with vasomotor symptoms than in women without vasomotor symptoms. In the postmenopausal group, the serum levels of IL-8 are similar to those in women with chronic inflammatory pathology. IL-8 could be a key factor in occurrence of hot flashes in menopause and could be associated with peripheral vasodilatation in these women.

    Bone Mineral Density and Proinflamatory Cytokines (IL-1ß and TNFa) in Menopause

    Acta Endo (Buc) 2014 10(2): 169-180 doi: 10.4183/aeb.2014.169

    Background. Osteoporosis has a high incidence after menopause, and at the same time the relationship between menopausal oestrogen deprivation and proinflammatory status is considered to be involved in postmenopausal bone turnover. Objective. The aim of this study was to evaluate the serum levels of IL-1β and of the TNFα in pre and postmenopausal women, as well as to investigate the relationship between these cytokines and bone mineral density. Design. A case-control study was performed during a period of 12 months. Subjects and Methods. The study included 150 women divided into 4 study groups. Serum levels of IL-1β and TNFα were determined using multiplex cytokine kits. BMD was measured by DXA at the level of the hip and lumbar spine. Results. Serum concentration of IL-1β is significantly higher in natural and surgically induced menopausal women, compared to women in the control group. Serum levels of TNFα in postmenopausal women and with surgically induced menopause are significantly higher than in fertile and premenopausal women. Serum levels of IL-1β are significantly higher in patients with osteopenia and osteoporosis compared to patients with normal BMD values. We found a negative correlation between serum levels of IL-1β, TNFα and BMD in pre and postmenopausal women, and in women with surgically induced menopause. Conclusions. Serum levels of IL- 1β and TNFα are significantly higher in menopausal women compared to fertile women. IL-1β is significantly higher in patients with osteopenia and osteoporosis than in women with normal BMD values, and IL-1β and TNFα associate negatively with BMD in pre and postmenopausal women, as well as in women with surgically induced menopause.
