The analysis of current literature data on the study of the features of the course of free-radical reactions, as well as the state of the antioxidant defense system at socially significant infectious diseases HIV infection, hepatitis, tuberculosis was carried out. The role of this kind of reaction in the genesis and progression of socially significant infections a long time has been studied. Foreign studies of recent years have been focused on the identification of specific markers of oxidative and carbonyl stress, which make it possible to identify the redox imbalance of the cell under conditions of infection and target affect it to modulate the activity of the main transcription factors of viral proteins and the bacteria pathogenicity. Numerous sources indicate the involvement of active oxygen metabolites in a wide range of events in infected cells and tissues, including neoplastic transformation processes. These biochemical markers can be used as additional criteria for monitoring the progression of infection. At the same time, noticeable gaps in this area there are that may become the goal of future research. The issues of changing free radical reactions depending on gender, age, place of residence of patients remain practically unstudied. There is little data about intensity of oxidative stress in patients of reproductive age with HIV, hepatitis B and C, and pulmonary tuberculosis, as well as the relationship of antioxidant deficiency with reproductive disorders in conditions of infection. These data could serve as the basis for the development of pathogenetically substantiated methods for the correction of socially significant infectious diseases. Modulation of the production of reactive oxygen metabolites and oxidative stress is a potentially new pharmacological approach to reduce the effects of viral and bacterial exposure.

Background: Information about involvement of general nonspecific reactions, in particular lipid peroxidation processes, in the progression of varicose veins of the pelvic (VVP) in women is still too scarce. Aims: To study the intensity of processes of lipid peroxidation and the activity of components of the antioxidant system in women with primary varicose veins of the pelvic at different stages of the disease. Materials and methods: 167 women of reproductive age were examined ― 137 with VVP and 30 made up a control group. All patients with VVP were divided into 3 groups depending on stages of the disease. Spectrophotometric and fluorometric methods of investigation were used. The study was conducted during 2012−2017. Results: It was revealed that the level of primary products of lipid peroxidation, diene conjugates, increased statistically significantly according to the stage of the disease by 1.25 times (in the 1st stage), 1.51 times (in the II stage) and 1.59 times (in the III stage) values. Changes in the content of final TBA-active products showed similar changes-an increase in the mean values for all stages of the disease relative to control (in 1.24, 1.17, and 1.77 times, respectively). Activity of glutathione peroxidase increased in stage 2 of VVP (1.19 times), with the maximum increase in stage III (1.42 times); activity of glutathione-S-transferase increased 1.18 times in the II stage of the disease. The concentration of GSH in the clinical groups was characterized by lower values with respect to the control (by 1.22 times in the 1st stage, in 1.64 times in the II stage), with the maximum decrease of this parameter in the III stage of VVP (3.67 times). The level of catalase activity increased in the I stage of VVP ― by 1.18 times and decreased in the III stage ― by 1.14 times with respect to the control. The activity of SOD showed similar changes with catalase ― in the form of increased activity at the 1st stage (1.35 times higher) and decreased values for II (1.35 times lower) and III (1.65 times lower) for the stages of VVP to the values of control. Conclusions: At progression of primary VVP in women (from the initial stage to the 3rd stage of the disease), there is an increase in imbalance in the lipid peroxidation − antioxidant defense system. Moreover, if the compensatory increase in activity of antioxidant enzymes is registered at stage 1 of the disease, then the most of the antioxidant defense factors decreases as relative to control values, and the initial stages of the disease.

Objective: The objective of this study was to identify features of the lipid status and lipid peroxidation-antioxidant defense system in women of reproductive age with acute form of hepatitis. Methods: The study involved 36 women with acute viral hepatitis and 28 healthy women of the same age. Spectrophotometric and fluorometric methods were used. Results: In patients with acute viral hepatitis we detected an increase in triglycerides levels ― by 21% and very low density lipoprotein values — by 17% in relative to control group, high-density lipoprotein cholesterol content reduced by 38%. In group with acute viral hepatitis the TBA-reactive products level increased by 2.21 times and superoxide dismutase activity decreased by 1.43 times in comparison with control group. Conclusion: The acute form of hepatitis is characterized by series of metabolic disorders that require a more careful approach in therapeutic and diagnostic administration.
