The epidemiology of the disease was discussed both abroad and in Russia, including the most up-to-date data. In Russia CKD markers were detected in 49.4% of hypertensives. Authors describe risk factors and mechanisms of CKD at the most important pathogenetic conditions: hypertension, diabetes and obesity. The current classification and methods for calculating the glomerular filtration rate are given. The review disclose a paradigm of the renal continuum and its relation to cardiovascular diseases. It is well known fact that the final causes of the death of patients with CKD, as a rule, are cardiovascular complications. Based on the literature data, the necessity and expediency of screening for renal dysfunction is justified. In the example of use of an angiotensin receptor blocker II - irbesartan nephroprotective demonstrated possibilities of intervention in patients with renal dysfunction of varying severity.

Membranous nephropathy (MN) is one of the most common causes of nephrotic syndrome in adults and is classified as either primary (idiopatic) or secondary MN according to underlying etiology (the later result from some known disease such as systemic autoimmune diseases, infections, malignancies, drugs, etc). In recent years, phospholipase A2 receptor 1 (PLA2R) and thrombospondin type-1 domain-containing 7A (THSD7A) were identified as two major podocytic antigens involved in the pathogenesis of idiopatic MN (IMN). And the discovery of circulating antibodies specific for these target antigens has transformed the diagnostic workup and significally improved management of IMN. However why do such antibodies develop is not conclusively established. The role of underlying genetic factors is discussed. The review presents the results of recent studies, that have shown significant associations of specific genetic factors (particularly human leucocyte antigen class II and PLA2R1 genes) with IMN.

Their efficacy is still being investigated. The use of biofeedback when teaching pelvic floor muscle exercises to patients increases the effectiveness of therapy. Objective: to assess the efficacy of biofeedback-assisted pelvic floor muscle training in patients with urinary incontinence after laparoscopic and robot-assisted radical prostatectomy and to compare the results of teaching. Materials and methods. A total of 64 patients with urinary incontinence after nerve sparing prostatectomy underwent biofeedback-assisted pelvic floor muscle rehabilitation. Radical laparoscopic surgery was performed in 48 (75 %) patients, whereas robot-assisted surgery was performed in 16 (25 %) patients. The patients started their training 2 months postoperatively. We used two-channel electromyography with the Neurotrack ETS system (United Kingdom) to teach the patients isolated pelvic floor muscle contractions. After achieving a minimum activity of abdominal muscles during pelvic floor muscle contractions, the patients started exercises. Results. There was no significant difference in age between patients who underwent laparoscopic and robot-assisted radical prostatectomy (р = 0.79). Fifty-five patients (85.9%) acquired the skill of isolated pelvic floor muscle contractions and could perform training on their own. The remaining 9 patients (14.1 %) required regular support from healthcare professionals at an outpatient unit (1-2 biofeedback-assisted trainings per month). Thus, the type of surgery did not affect the process of training. The type of radical prostatectomy had no impact on the acquisition of the pelvic floor muscle contraction skill. Conclusion. The time for restoration of urinary continence by biofeedback-assisted pelvic floor muscle training did not vary between patients after laparoscopic and robot-assisted radical prostatectomy.

There is a category of patients with renal masses, due to severe concomitant diseases, can not perform the operation or may be associated with a threat to life. In addition, many patients with small tumor sites are extremely concerned about their disease and are negative about the tactics of active observation and insist on treatment. These patients can be offered alternative methods of treatment of renal cell carcinoma (RCC), the leading of which is cryoablation. Objective: to evaluate the effectiveness and safety of percutaneous cryoablation of the kidney tumor under ultrasound control. Materials and methods. In the Urology Clinic of the I.M. Sechenov First Moscow State Medical University during the period from 2015 to 2017 performed 23 percutaneous cryoablation of RCC, 7 (men - 4, women - 3) of which were performed under local anesthesia. In 4 patients due to severe concomitant diseases, general anesthesia was associated with an extremely high risk. Three patients refused from dynamic observation and from traditional surgical treatment; preferred an alternative treatment in the form of a percutaneous cryoablation under local anesthesia. In 4 cases, the formations were located in the lower segment along the posterior surface of the kidney, in 3 - along the lateral surface in the middle segment. The size of the formations was not used 4 cm (T1a). The age of the patients was 62.3 years (51 to 83 years). Right-sided localization of the tumor was noted in 3 patients, left-sided - in 4. One patient had a single kidney. At the preoperative stage and 6 months after the operation, all patients underwent ultrasound with dopplerography, multislice computerized tomography with contrast, and computer 3D modeling, which helped to clearly assess the size of the tumor, clarify the prevalence of the tumor process and the spatial ratio of the internal surface of the tumor node to the elements of the bowl-and-pelvis system. In all the observations, the formations were located along the posterior or lateral surface of the kidney; in the lower or middle segment; without invasion of the sine. We used a 3 rd generation cryomash machine SeedNet gold (Galil Medical), cryoprobes IceSeed and IceRod. Intraoperative, immediately before cryoablation, a tumor biopsy was performed, the presence of RCC in all patients was confirmed morphologically. Results. According to the ultrasound examination with echodopplerography at 6 months after the operation, the size of the tumor node's formations decreased on average by 6-8 mm, while there was no blood flow in them. When multislice computerized tomography with 3D modeling was performed, the formation was reduced and the accumulation of the contrast preparation was completely absent or their accumulation gradient did not exceed 10 HU (initially it was about 200 HU). There were no intraoperative complications. In 1 observation, a postoperative hematoma measuring 7 × 3 cm was resolved conservatively and did not require surgical treatment. Conclusions. Percutaneous cryodestruction under local anesthesia using ultrasound guidance seems to be an effective and safe technique for treating patients with stage T1a RCC with localization in the posterior or lateral surface in the lower or middle segments without invasion of the renal sinus and surrounding tissues. It is planned to continue monitoring patients to assess the long-term effectiveness of cryoablation.

The purpose of the study was to present data on polymixin-based antibiotics with activity against infections caused by multidrug-resistant Gram-negative bacteria, such as Acinetobacter baumannii, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Material and methods. The review includes data from clinical as well as in vitro studies for the period 1998–2017. The search for relevant sources was carried out in the Medline, Cochrane Library, Elibrary and other databases. Results. The analysis of the data showed the presence of synergism and additive activity of polymyxin in combination with carbapenems, rifampicin and azithromycin. However, experimental data showed no direct positive correlation between combination of polymyxim and azithromycin/ rifampicin. In clinical studies, in hospital-acquired pneumonia, including ventilator-associated pneumonia, the clinical response rate of polymyxin B combined with other antibiotics ranged from 38 % to 88 %. High nephro- and neurotoxicity of polymyxin observed in previous studies can be explained by a lack of understanding of its toxicodynamics or the use of an incorrect dose. Conclusion. Polymyxin B in combination with other antibiotics is a promising treatment against infectious complications caused by multidrug resistant Gram-negative bacteria.

The choice of the reconstruction technique depends on the tumor size and localization, type of the defect, patient’s age, concomitant diseases, and disease prognosis. Surgeons have currently a broad range of material for reconstructive surgery, from free flaps to revascularized flaps. Microsurgical reconstruction has made a revolution in treatment of patients with complex head and neck defects. However, the use of this technique may not be advisable for some patients. The search for new techniques is needed to improve functional and aesthetic results and reduce traumatism without compromising oncologic outcomes. Thirty-six patients underwent surgery with reconstruction using the submental island flap, a new alternative in the reconstruction of various head and neck defects. The graft was taken after making a neck incision for neck lymph node dissection. A few patients develop total and marginal necrosis of the graft. Short- and long-term results showed no worsening of oncologic outcomes in the selected group of patients.

The outcome of diseases accompanied or caused by mucostasis depends both on the restoration of drainage function of the airways and on the effectiveness of immune mechanisms against pathogens. N-acetylcysteine (NAC) is widely used as mucolytic and antioxidant remedy in clinical practice. In this regard, the data of the scientific literature on the direct and indirect effects of NAC on the mucosal immunity of the respiratory tract have been reviewed. NAC possesses pleiotropic immunomodulating properties, most of which contribute to the regression of clinical manifestations of acute and chronic inflammatory diseases of the respiratory tract. Biological and pharmacological effects of NAC include improvement in rheological properties of mucus, reduction of excess mucin production, restoration of mucociliary clearance and production of sIgA, suppression of excess production of IgE and IgG4, destruction of biofilms and inhibition of their formation, suppression of adhesion of pathogenic bacteria to epithelial cells, antioxidant activity, regulation of the production of pro-inflammatory and profibrotic cytokines. There was no convincing evidence that NAC is able to suppress any component of mucosal immunity. For final conclusions on this subject, further research are required.

In-depth study of the function and structure of the lymphoid tissue of the gastrointestinal tract and respiratory tract opens wide opportunities for the use of mucosal vaccines to improve immunity to various infectious agents. One such drug is The immunovac-VP4 vaccine containing pathogen-associated molecular structures (PAMSs) of microorganisms. They are the antigens of Klebsiella pneumoniae, Proteus vulgaris, Escherichia coli, Staphylococcus aureus. Discovered in many studies and experiments, the ability of the vaccine to induce innate immunity provides opportunities for prevention and treatment of both infections and allergic diseases, because it promotes the switching of Th2 immune response to Th1. The aim of the study was to study the effectiveness of the complex use of bacterial therapeutic vaccine Immunovac-VP4 and allergen-specific immune therapy (ASIT) in pollinosis in children and adults. Materials and methods. Bacterial therapeutic vaccine Immunovac-VP4 was used annually, nasal and oral administration in patients before the course of ASIT standardized aqueous-salt solutions of allergens. Results. The therapeutic application of bacterial vaccines, Immunoac-ÂÏ4 before the course ASIT has helped to reduce the frequency of acute respiratory infections in 8,5 times in comparison with the control group. Clinical efficacy of complex treatment according to the results of the survey of patients in 7 years after the start of therapy was 90%. There was a significant decrease In IgG4 to causally significant allergens, General immnunoglobulin E (IgE) and a tendency to decrease IgE. Conclusion. The use of bacterial therapeutic vaccine Immunovac-VP4, which is a natural ligand of toll-like receptors in combination with ASIT, seems to be an effective and promising direction in the treatment of allergic diseases.

The results of a clinical study showing the importance of surfactant proteins A and D in assessing the activity and progression of idiopathic pulmonary fibrosis and chronic lung sarcoidosis are presented. Aim. To study the clinical significance of SP-A, SP-D in assessing the activity of idiopathic pulmonary fibrosis and sarcoidosis. We examined 81 patients with morphologically confirmed diagnoses of idiopathic pulmonary fibrosis (ILF) and sarcoidosis, a control group of 20 healthy individuals. The MSCT of the thoracic organs of the chest was performed, the diffusivity of the lungs was examined, oxygen saturation was determined. In the serum, the surfactant proteins SP-A and SP-D were determined by the enzyme-linked immunosorbent assay. Results. A significant increase in SP-A and SP-D (p<0.05) was observed in patients compared with patients in the control group, a direct correlation was found with signs of activity: SP-A with alveolitis (p<0.05), SP- D with progressive fibrosis (p<0.05), inverse correlation of surfactant proteins with respiratory function indices (p<0.05). Conclusion. Serological parameters of SP-A and SP-D reflect the activity of alveolitis and the progression of pulmonary fibrosis in patients with ILF and sarcoidosis.

At present, compelling evidence has been obtained that combined therapy of pulmonary arterial hypertension (PAH) with specific drugs can significantly slow progression of PAH. Therefore, in current guidelines combination therapy is already considered as standard treatment for a significant proportion of patients with moderately severe and severe forms of PAH. However, the quality of life and long-term prognosis of patients receiving combination therapy, should be the object of further research. The future research is absolutely necessary to identify the most optimal strategy of treatment of patients with PAH, such as initial combination therapy or rapid sequential combination therapy, double or triple combinations as well as exploring new signaling pathways PAH, which can become targets for new specific drugs PAH.

Systemic vasculitis is a heterogeneous group of inflammatory diseases, which are classified according to the diameter of the affected vessels. The treatment of systemic vasculitis is no longer empirical, because of increasing number of randomized clinical trials in this field. In recent years, there was a trend to limit the cumulative dose of glucocorticosteroids and immunosuppressive drugs, partially through biological drugs usage. However, biologic therapy is not always superior to combination of glucocorticosteroids and cytotoxic drugs. The efficacy of different biologic drugs varies in patients with different forms of systemic vasculitis, which creates the ground for personalized therapy of these diseases. Another serious problem is the absence of strict criteria to immunosuppressive therapy intensification, especially in vasculitis, affecting large vessels, due to the lack of reliable laboratory markers of disease activity. The article reviews modern approaches to the treatment of some types of systemic vasculitis, including ANCA-associated vasculitides, giant cell arteritis, Takayasu`s arteritis and cryoglobulinemic vasculitis.

© Russian Journal of Cardiology. Aim. To assess possibility and safety of intervalic hypoxic-hyperoxic training (HHT) as a method of cardioprotection and metabolic adaptation of myocardium for onpump coronary bypass surgery. Material and methods. Totally, 80 coronary heart disease patients included, hospitalized to the clinics of aortic and cardiosurgery of the University hospital of Sechenov University. All had indications for the operation — direct myocardial revascularization with bypass grafting. In 5 days before surgery, according to the scheme of preparation, the patients were randomized to two groups (main — with HHT, and controls; n=40). The rate of complications was evaluated, during the operation and in post-surgery period. The level of troponin I was measured before operation, in 2 and 24 hours after, as well as level of lactate in venous blood before and after operation. Results. The rate of intra- and early postsurgery complications in both groups did not differ significantly, though in the main there was tendency to decline of total rate of complications. In patients of HHT group median troponin I was significantly lower: 1,068 (0,388; 1,397) ng/L, when in controls — 1,980 (1,068; 3,239) ng/mL, р=0,012. Lactate level after HHT operation was significantly lower — 1,74 (1,23; 2,04) mM/L, comparing to the controls — 2,10 (1,80; 2,29) mM/L, р=0,04. Conclusion. The applicability and safety were demonstrated, of HHT as a method of cardioprotection in shunting of coronary arteries on-pump. Taken low number of participants, it is important to conduct broader investigation on this type of entrainment.

A literature review provided, on the usage of various schemes of perioperational anticoagulation therapy (ACT) in atrial fibrillation patients undergoing scheduled surgery. It is noted that clinicians quite often pass through a situation when patients taking ACT require invasive investigations and surgery. Perioperational management of such category of patients is complicated as, on the one hand, the surgery under ACT is associated with intraoperational hemorrhagic complications, and, on the other hand, ACT cessation might increase the risk of thrombotic complications. The variants assessed, of different periprocedural ACT in patients taking vitamin K antagonists. It was found that as an alternative to continuous ACT recently, bridge therapy with low molecular weight heparins applied, aiming the decrease of the risk of bleeding in adequate thromboprophylaxis. The results of clinical trials provided on the assessment of bridge therapy in surgery. Risk stratification approaches presents for thromboembolic and hemorrhagic complications in surgery.

The spread of a latent tuberculosis infection - 2.3 billion people - is of emergency importance for the global task of mankind - to eliminate tuberculosis as a common disease by 2035. For children, due to the limited use of the radiological diagnosis methods, the main methods today are the immunological tests for the detection of tuberculous infection. The most common used method is the tuberculin skin test (Mantoux test) due to its lack of specificity has significant drawbacks, especially in countries using mass BCG vaccination. Relatively new methods using specific recombinant MTB proteins, both in vitro tests and in new skin tests, allow to determine tuberculosis infection in latent or active form much more specifically, however, they are somewhat less sensitive, in comparison with the Mantoux test, which requires development of these methods with the introduction of new additional specific antigens. It is obvious that crucial task is the development of new methods for distinguishing active and latent tuberculosis infection or being able to predict progression from latent to active TB diseases both in children and in adult population. The article shows new diagnostic techniques of blood cells and plasma samples based on the use of flow cytometry with the detection of antigen-specific T-cells producing interferongamma and tumor necrosis factor alpha, T-cells specific markers, as well as using combinations of the identification of various protein factors that have the prospect to determining active tuberculosis infection signs. However, these methods are still time-consuming and expensive. Currently, some new promising approaches based on the using of new genetically engineered products are being developed to determine specific antibodies in the blood serum. With the development of accelerated methods for the analysis of the expression of specific genes in blood cells, this direction also has the prospect of introducing into healthcare practice.

© 2018 Stolichnaya Izdatelskaya Kompaniya. Cardiovascular diseases occupy a leading position in morbidity, mortality and disability in most countries. Ischemic heart disease and stroke lead in the structure of mortality from cardiovascular diseases. The issues of lipid-lowering therapy with statins in the aspect of stroke prevention are discussed in the article. The main risk factors of atherosclerosis and their prevalence are presented. Topical standards for statin use, evidence-based medicine data obtained in randomized clinical trials, and evidence from actual clinical practice are covered. Possible promising areas of statin use for the prevention of acute cerebrovascular accident are also considered. Combination therapy together with other lipid-lowering drugs, as well as drugs of other pharmacological groups, the use of statins from earlier ages, the practical implementation of pleiotropic effects of statins can be attributed to the latter. The authors clearly demonstrate that the actual practice of using statins lags significantly behind the ideal, reflected in the recommendations and randomized clinical trials. Adherence to medical recommendations is one of the key factors in this. The main factors that can influence the increase of adherence of patients to taking statins and increase the effectiveness of their application in real clinical practice are presented..
