RESUMO

We analyzed the blood concentration of pro- and anti-inflammatory cytokines in the ovarian vein basin area in women of the reproductive age with primary pelvic varices. Increase in the disease severity was accompanied by a significant increase in proinflammatory cytokines (TNFα, IL-1ß, IL-2, IL-6, and IL-8) and the proinflammatory index (IL-6/IL-10), whereas anti-inflammatory cytokine production changed ambiguously (increase of IL-4 at stage I, decrease of IL-10 at stage II, significant decrease of IL-4 and IL-10 at stage III). Control of these changes in female patients should probably be an important component of treatment measures and prevention of morphofunctional disorders occurring at disease progression, in particular at stage III of the disease.

RESUMO

Pelvic venous disorder (PVD) in women is a polyetiological multifactorial disease characterized by a high prevalence (up to 80%), a high risk of infertility, and a progressive recurrent course. Morphological changes of the venous bed occur in PVD, contributing to retrograde blood flow and pelvic phlebohypertension. It is occur due to dynamic hypervolemia and hypertension long-term exposure on the venous wall. However, PVD pathogenesis analysis only from venous hemodynamic disorders position does not explain all mechanisms of the disease development and does not contribute to the treatment measures effectiveness. Currently oxidative stress reactions are considered as the most important markers of the pathological process. The aim of our work was a comparative analysis of lipid peroxidation-antioxidant defense component changes in the peripheral and regional blood flow in women with primary pelvic venous disorder depending on the disease stage. The study involved 137 women of reproductive age (mean age 37.4±9.1 years old) with diagnosed primary PVD divided into 3 groups according to the pathological process stages (stages I, II, III). Data from 30 practically healthy women (mean age 33.5±6.3 years old) were used as controls. Spectrophotometric, fluorometric, immunoassay and statistical methods were used. In patients with PVD stage I in peripheral bloodstream were higher values of SOD and GPO activity; in the regional bloodstream were higher levels of TBARs, SOD, catalase, GPO and lower GSH. In PVD stage II the peripheral bloodstream showed elevated levels of DC, GSH and SOD reduced levels; the regional bloodstream showed higher levels of DC, TBARs, GPO and GSH reduced levels relative to controls. PVD stage III was characterized by: higher levels of DC and TBARs and lower levels of SOD and GSH in the peripheral bloodstream; higher levels of DC, TBARs and lower levels of GSH and catalase in the regional bloodstream compared with control. Thus, the results of our study showed no significant differences in the LPO-AOD system between peripheral and regional bloodstreams in patients with PVD depending on the disease stage. However, negative changes in the redox balance in the regional bloodstream were earlier and were already registered at the first stage of the disease. It is likely that control of antioxidant insufficiency in patients with PVD should be an important component of preventive measures in the early stages and pathogenetic treatment in the pathological process progression, particularly in stage III of the disease.

RESUMO

Activity of some antioxidant enzymes (superoxide dismutase, catalase, and glutathionedependent enzymes), as well as the level of LPO products in the region regional blood flow (collateral branches of the main trunks of ovarian veins) in women with pelvic venous disorders were studied. A compensatory increase in activity of superoxide dismutase, catalase, and glutathione peroxidase during stage I of the disease was found; during stage II, superoxide dismutase activity decreased and glutathione peroxidase increased, while during stage III, pronounced decrease in activities of all studied enzymes was observed. The level of lipid peroxidation products in the regional blood flow increased as the disease progressed, with maximum values in the third stage.

RESUMO

Specific features of LPO processes and antioxidant defense were studied in patients with polycystic ovarian syndrome (PCOS) and infertility. Changes in LPO processes in patients with PCOS were compensatory, which manifested in increased α-tocopherol and retinol concentrations and moderate decrease in superoxide dismutase activity. Intensification of prooxidant processes was found in the group of patients with infertility without PCOS. The observed changes necessitate differentiated approach to the treatment of these patients.
