Exosomes (vesicles with the size of 30-150 nm) are formed in multivesicular bodies (MVB) by invagination of early endosome membranes and mediate intercellular interactions. Exosomes are secreted by various kinds of cells, their content might be represented by proteins, lipids and nucleic acids, which reflect the functional state of donor cells. The effect of exosomes on recipient cells depends on their quantity and characteristics of their «load». Comparatively recently, placental exosomes secreted by various placental cells have been isolated from blood of pregnant women. A specific protein - placental alkaline phosphatase (PLAP) - has been determined for these exosomes. PLAP-positive exosomes can be found in maternal blood as soon as in the first trimester of pregnancy, their number increases with maturation of the foetus and reaches its maximum by the moment of birth. Although the functional significance of placental exosomes is still investigated, some authors relate changes in the placental exosome profile (their number and composition) to placental dysfunction underlying the development of complications of pregnancy. Isolation of exosomes from blood of pregnant women (fluid biopsy) and determination of their biological characteristics might be regarded as early noninvasive diagnosis of structural and functional placental abnormalities. The appearing evidence of blastocyst-secreted exosomes and their role in modulating maternal immunity and endometrial receptiveness during implantation are also promising. The review presents data about the biogenesis, structure and functions of exosomes and the role of placenta-associated exosomes in the development of physiological and complicated pregnancy, and also about the possibility of using exosomes as a marker of the state of the blastocyst in assisted reproductive technologies, in particular, in oocyte donation and surrogate motherhood.

In the affected families, there is a higher risk of the child's impaired emotional, social and cognitive development. Post-partum depression is one of the most common complications of the postnatal period. The disease prevalence varies from 6.5 to 12.9% and more in countries with low and middle levels of income and life. We analysed 62 Russian and worldwide literature sources published in the PubMed, Google Scholar databases and in Russian medical periodicals over the period 2002-2017 on this theme, we also translated the original Edinburgh Postnatal Depression Scale. This systematic review presents current ideas of the causes of postpartum depressions, methods of treatment and prevention.

Inflammasomes are macromolecular complexes that contain many copies of receptors recognizing molecular patterns of pathogenic agents (PAMP) and damage-associated structures (DAMP), and also include molecules of adapter protein ASC and procaspase- 1. Activation of inflammasomes leads to the formation of active caspase-1 that, in turn, provides the maturation of pro-IL-1β and pro-IL-18 to IL-1β and IL-18. The latter cytokines play an important role in control of neuroinlfammation in the central nervous system contributing to the pathogenesis of a series of neurological, neurodegenerative and mental disorders. The review discusses the involvement of NLRP3 inflammasome and other their types in the development of the traumatic brain injury, ischemic and hemorrhagic stroke, brain tumors, CNS infections, Alzheimer’s and Parkinson’s diseases, epilepsy, amyotrophic lateral sclerosis, depressiver, and consequences of alcohol abuse. The elucidation of molecular mechanisms and signaling pathways controlled by inflammasomes will allow the development of new therapeutic measures for diseases, in which neuroinflammation plays a leading pathogenetic role.

These drugs increase BDNF level in CNS and adult hippocampal neurogenesis, which events are in common for both NMDA receptor modulators and classical antidepressants. However, unlike classical antidepressants, drugs of this new group produce no direct influence on the monoaminergic system, but regulate the neuroplasticity in the prefrontal cortex and hippocampus via modulation of the glutamatergic neurotransmission. Clinical tests of ketamine and rapastinel confirmed the rapid onset of action and the continuation of stable antidepressant effect (upon single administration per 7 days) for both usual and treatment-resistant forms of depression.

To study the effectiveness of two-step treatment of female patients with cervical intraepithelial neoplasia (CIN) associated with papillomavirus infection (PVI). Patients and methods. 126 female patients of reproductive age were examined (mean age – 31.4 ± 2.1 years), in whom CIN was associated with papillomavirus infection (PVI). In all cases, cervical pathologies – low-grade squamous intraepithelial lesions (L-SIL) have been found. In all patients treatment included a surgical step (laser and plasma energy) and medication, which was employed in 101 (80.1%) patients (treatment group). 25 (19.9%) women comprised the control group, since they did not receive post-operative pathogenetic therapy. In the treatment group, patients received an immunostimulating and antiviral drug inosine pranobex (IP) – Isoprinosine. Results. The effectiveness of treatment was assessed after 60 and 120 days from the termination of complex therapy (treatment group), or surgical intervention (control group). After a 60-day period, complete elimination of virus was noted 97 (96%) patients of the treatment group and in 18 (72%) of the control group. After 120 days, PVI relapse was recorded in 3 women of the treatment group (3%) and in 4 (22%) – of the control group among patients with complete elimination of virus. Conclusion. The use of IP as monotherapy is an optimal solution ensuring minimal risks of relapses of pathological PVI. Preparations of pure IFN and their inductors do not always promote complete elimination of PVI owing to interferon resistance of HPV-infected patients.

Purpose: Complications after hip/knee/other joint arthroplasty develop in approximately 1-1.5% of young people and in 2.5-3% of elderly patients. Despite the meager chance of developing negative consequences, they can affect anyone, especially those who did not follow the rigorous rehabilitation program. Complications after endoprosthetics of hip/knee/other joints results from incorrect postoperative care and physical activity after discharge from the hospital. The second reason is technical approach of the surgeon. And third is an inadequate preoperative examination. The aim of the article is to have a detailed description of short term, midterm and long-term complications after joint replacement surgeries and of the methods (clinical and radiological) to avoid those complications with all the required parameters.

Overweight provokes many metabolic and hemodynamic disorders. About 30% of inhabitants of the planet have overweight and prevalence of obesity increases by 10% every 10 years according to the WHO data. The probability of arterial hypertension in obese patients is 50% higher than in people with normal body mass. Framingham study showed that obesity is an independent, significant risk factor of ischemic heart disease, myocardial infarction, cerebral stroke and diabetes mellitus. The most dangerous is the central obesity with the preferential fat deposition in the abdomen. Combination of visceral obesity, violation of carbohydrate and lipid metabolism, arterial hypertension, and close pathogenic relationship between these factors underlie the isolated symptom complex known as metabolic syndrome. J. Vague was the first to describe relationship between abdominal obesity with cardiovascular disease and mortality in 1947. In our country G.F. Lang noticed common combination of arterial hypertension with obesity, lipid and carbohydrate metabolism disorders. Thus, metabolic syndrome significantly increases risk and severity of cardiovascular disease. Within last decades criteria of metabolic syndrome stays constant. The factors of insulin resistance and endothelial dysfunction as stages of the pathogenesis of the metabolic syndrome have been studied in detail. The mechanisms of insulin resistance and endothelial dysfunction are discussed in detail in this article as well as inflammatory markers and the significance of highly sensitive C-reactive protein.

Patients and methods. 120 women aged 18-65 years with recurrent depressive disorder (RDD; ICI-10 F33) (a study group) and 67 men of the same age with RDD (a control group) were clinically examined using a specially designed schedule and the Montgomery-Asberg Depression Scale. Results. The clinical picture and the course of RDD have gender differences. The earlier onset of the disease in women with a large number of depressive attacks and lower quality remissions is due to the relationship and mutual influence of menstrual and reproductive function and depression. Such typical symptoms of endogenous depression, as slow thinking, anhedony, decreased sleep duration and early morning awakenings, as well as diurnal swings of mood with its deterioration in the morning, were characteristic for most women and men. The pattern of depression in women is more commonly characterized by anxiety; ideas of self-accusation; suicidal thoughts; avoidance of contacts with others; weakness; fatigue; decreased or increased appetite; sleep onset insomnia; lack of sleep feeling. That in men is more often marked by symptoms, such as melancholy; motor retardation; decreased motivation; somatic symptoms of depression (tachycardia, constipation); comorbid panic attacks; and concomitant diseases of the cardiovascular, respiratory and genitourinary systems. Men more frequently abuse alcohol and other psychoactive substances. Conclusion. The revealed features of depression in women and men will be able to more accurately diagnose and to prescribe adequate therapy.

Objective: to study of the individual aspects of the relationship and interaction of menstrual and generative function and depressive disorders in women. Patients and methods. 120 women aged 18-65 years with recurrent depressive disorder (RDD) who had experienced at least two depressive episodes (a study group) and 120 mentally healthy women of the same age (a control group) were clinically examined using a specially designed map with subsequent statistical processing of the findings. Results and discussion. In 71.7% of women, depression manifests itself during hormonal rearrangement periods (puberty, postpartum, and menopause). 65.0% of women with RDD have premenstrual syndrome (PMS), the pattern of which shows depressive symptoms. Depression affects menstrual function: the later onset and irregularity of menstruation, the earlier restoration of menstrual function after childbirth, and the earlier onset of premenopause, which has an adverse impact on generative function (a reduction in the number of pregnancies, births, and babies). Depression, the onset of which is observed during puberty, exerts the most malignant effect on menstrual and generative function. Overall, depressive patients are less socially and family-friendly than healthy women. Menstrual and generative function and adaptation minimally suffer in women with postmenopausal depression. Conclusion. The onset of depressive disorders is associated with the hormonal rearrangement periods. The presence of depressive symptoms in the pattern of PMS is a prognostic sign of future depression or indicates partial remission. At the same time, menstrual function is impaired in women suffering from RDD, which along with psychic manifestations of depression (a decrease in sexual drive and contacts, as well as anesthesia of feelings, etc.) leads to infertility.

The antidepressant-like effect of fluoxetine (20 mg/kg i.p.) has been assessed using the forced swimming test (FST) in IRC (CD-1) mice exposed or not to a pretest session of different duration (5 or 20 min). The influence of the mitochondrial translocator protein (TSPO) activity on the antidepressant-like effect of fluoxetine (20 mg/kg i.p.) in the FST was also studied. The antidepressant-like effect of fluoxetine was observed only in mice subjected to a 5-min pretest session 24 h before the FST. The TSPO antagonist PK11195 [1-(2-chlorophenyl)-N-methyl-N-(1-methylpropyl)-3-isoquinolinecarboxamide; 1 or 3 mg/kg i.p.] inhibited the antidepressant activity of fluoxetine in the FST. In the present study, fluoxetine or PK11195 was administered for a short duration. We suppose that the functional activity of TSPO may depend on a pretest session and that using this procedure is necessary to detect antidepressant activity of fluoxetine-like drugs.

The objective: To optimize a tactics of examination and treatment of patients with a benign cervical pathology associated with papillomavirus infection (PVI) in female patients of reproductive age. Patients and methods: 124 patients aged 22 to 35 years underwent complex examination and treatment. Two groups were singled out: the first (main) group included 72 patients, who in the postoperative period received treatment with an antiviral immunostimulating drug isoprinosine, the second group comprised 52 patients, who did not receive the antiviral medication (control group). Inosine pranobex (isoprinosine) was administered 3 g/day (2 tablets 3 times daily) for 28 days. A carbon dioxide (CO2) laser and argon plasma were used to destroy the affected uterine cervical epithelium. Results: The Pap test found various pathological changes in 112 (90.3%) patients. ASCUS smear results had similar incidence rates in the groups 16 and 18% (p > 0.05). The incidence of LSIL in the groups was 31.9 and 32.6%, respectively (p > 0.05). In the basic group, 60 days afterwards complete elimination of virus was noted in 95.8% of cases; in the control group in 78.8%. The frequency of HPV infection recurrence among patients with complete virus elimination was 2.9% in the basic group, in the control group - 14.6%. Conclusion: The employment of the surgical stage permits to destroy pathological tissue, deactivate virus at the local level and prepare conditions for deactivation of virus in the body. Postoperative antiviral and immunostimulating therapy not only ensures practically complete elimination of virus but also reduces recurrences of PVI.

© 2018, Media Sphera Publishing Group. All rights reserved. Objective. To study the association between proinflammatory cytokine genes and depression. Material and methods. IL-1B С-511T and TNF-a G-308A gene polymorphisms were studied in patients diagnosed with depression and age and sex-matched healthy controls. Results and conclusion. The IL-1B С-511T and TNF-a G-308A polymorphisms were associated with depression; CC genotype (р=0,001, OR=1.9 CI 1,3—2,7) and GG genotype (р=0,001, OR=3,0 CI 1,8—4,9) were the risk factors. The results suggest that immune factors may play a role in the development of depression. The authors highlight the role of clinical polymorphism of depression that makes it difficult to form homogenous groups of patients and to select phenotypes for biological studies.

However, the prevalence and phenotype of such impairment in chronic migraine have not been studied. Objective-to evaluate the prevalence of the objective cognitive deficit in patients with chronic migraine and factors underlying its etiology. Materials and methods. We recruited 62 subjects with chronic migraine and 36 gender-and age-matched controls with low-frequency episodic migraine (not more, then 4 headache days per month) aged 18-59. All patients filled in the Hospital Anxiety and Depres sion Scale (HADS) and Sheehan Disability Scale. Cognitive function was assessed with the Montreal Cognitive Assessment (MoCA), Digital Symbol Substitution Test (DSST), Rey Auditory Verbal Learning Test (RAVLT), and the Perceived Deficits Questionnaire (PDQ-20). Results. In this study 58 % of patients with chronic migraine complained of memory loss. Cognitive impairment was also found with PDQ-20. Objectively, we found a significant decrease in 90-second DSST results and RAVLT total recall and learning rate. In 40 % of subjects with chronic migraine scored lower than 26 points on MoCA. Patients with chronic migraine more frequently had lower DSST rates as compared to episodic migraine (odds ratio 5.07 (95 % confidence interval-1.59-16.17); p = 0.003). Depression and anxiety did not correlate with performance on cognitive tests. Chronic migraine (frequent headache) and longer headache history, but not depression, anxiety or medication overuse were independent predictors of cognitive impairment. Conclusion. Subjective and objective cognitive deficits are prevalent in the chronic migraine population. Most often memory and attention are impaired. Longer headache history and presence of chronic migraine are independent risk factors for cognitive impairment in patients with chronic migraine.

The drug has a unique receptor profile, being a melatonin receptor type 1 and 2 agonist and a serotonin receptor subtype 2C antagonist. Due to this and in addition to antidepressant action, the drug has a number of other effects, such as analgesic, anti-apathetic, anti-asthenic, procognitive, anxiolytic, and sleep-normalizing ones, which are of great importance in the treatment of neurological diseases. There are clinical and experimental data that prove the high efficiency and safety of agomelatin in the follow-up of patients with post-stroke depression, Parkinson's disease, Alzheimer's disease, Pick's disease, Huntington's disease, chronic fatigue syndrome, and pain syndromes.

The superfamily of nuclear receptors represents ligand-activated transcription factors and includes receptors for steroid hormones, lipophilic vitamins, sterols, and bile acids. These receptors serve as targets for creating numerous drugs. As a result, a new class of compounds (ligands) appeared exhibiting agonistic/partial agonistic/antagonistic functional activities depending on the context (tissue or gene target). This class of ligands is called selective modulators of nuclear receptors. Initially, mifepristone was developed as the progesterone receptor antagonist, but further it demonstrated the properties of a selective modulator of progesterone receptor and became the ancestor of this group. At present, the development of new selective modulators of progesterone receptor is aimed at obtaining higher selectivity with respect to progesterone receptors and decreasing the anti-androgenic and anti-glucocorticoid properties. Unfortunately, most of the subsequent selective modulators of progesterone receptors exhibited hepatotoxicity, which limited their wide introduction into clinical practice.

Tumour necrosis factor alpha inhibitors are widely used in the treatment of juvenile idiopathic arthritis (JIA). To achieve maximum efficiency of genetically engineered biologic drugs, it is necessary to study predictors of the response to therapy. Objective. Our aim was to identify early predictors of the response to adalimumab therapy in patients with JIA without systemic manifestations. Methods. A prospective cohort study analysed treatment results of patients with JIA without systemic manifestations, who were prescribed adalimumab for the period from August 2008 to August 2014. We studied the relationship between baseline demographic indicators as well as baseline and registered after one month of treatment clinical and laboratory parameters and the best (remission according to the Wallace criteria) response to therapy after one year. Results. In the first year of therapy, 94 (43.9%) of 214 patients achieved remission according to the Wallace criteria. In a multivariate analysis, predictors of achieving remission after one year of adalimumab therapy were the improvement according to the ACR70 criterion after one month of therapy [odds ratio (OR) 3.3; 95% confidence interval (CI) 1.7-6.7], a history of uveitis (OR 1.86; 95% CI 1.03-3.33), a decrease in the number of joints with active arthritis after one month of therapy (OR 1.09; 95% CI 1.02-1.16). During therapy, injection reactions in the form of pain were observed in 36 (16.8%) of 214 patients, infectious diseases of ENT organs - in 85 (39.7%), of the respiratory tract - in 17 (7.9%), and tubinfection - in 13 (6.1%) children. Conclusion. The presence of uveitis, rapid reduction in the number of joints with active arthritis and a high level of response to treatment after one month of adalimumab therapy are predictors for achieving remission during the first year of treatment.

© 2018, Media Sphera Publishing Group. All rights reserved. Objective. To study cognitive functions, anxiety and depression levels, 24-hour blood pressure (BP) profile, cerebral blood flow (CBF) perfusion in treatment-naive middle-aged patients with uncomplicated essential arterial hypertension (EAH) depending on the white matter hyperintensities (WMH) burden. Material and methods. Forty-one hypertensive patients (mean age 46.2±4.6 years) and 41 healthy volunteers (mean age 50.3±6.7 years) were enrolled to the study. All subjects underwent brain MRI (MAGNETOM Skyra 3.0T, T1, T2 FSE, T2 FLAIR, T1 MPRAGE, ASL), Montreal cognitive assessment (MoCA), 10-word learning task, verbal fluency test, trail making test, Stroop color and word test, anxiety and depression assessment with Hamilton rating scales, 24-hour blood pressure monitoring (ABPM). Results. WMH were found in 22 (53.7%) hypertensive patients and in 3 (7.3%) healthy volunteers (p=0.0002). Hypertensive patients had the significantly lower CBF compared to controls (p<0.001). Conclusion. WMH were identified in treatment-naive middle-aged patients with uncomplicated mild to moderate EAH. There was an association between WMH and lower CBF in the cortical plate of frontal lobes, SBP variability and worse cognition. Cerebral hypoperfusion can cause cognitive impairment even in the earliest stages of EAH, which increases due to emotional disorders.
