Objective: to investigate the short- and long-term results of surgical median nerve decompression via classical and minimally invasive approaches in patients with carpal tunnel syndrome (CTS), as well as factors that influence surgical outcomes. Patients and methods. The investigation enrolled 70 patients (13 men and 57 women) aged 36 to 84 years (mean age, 62±10.8 years) who had undergone median nerve decompression. Surgery was performed in the classical way in 35 patients (Group 1) and via a minimally invasive access in the remaining 35 patients (Group 2). The efficiency of treatment was evaluated using the Boston Carpal Tunnel Questionnaire (BCTQ) and a visual analog scale for pain before and 1, 3, 6, and 12 months after surgery, as well as from patient satisfaction with surgical outcomes. Results. No complications of surgical treatment were detected. There was a marked reduction in pain and other neuropathic disorders just 1 month after surgery and a substantial hand functional improvement following 6 months. After 12 months, in Group 1, the mean BCTQ Symptom Severity Scale and Functional Deficit Scale scores decreased from 2.76 to 1.15 (p≤0.01) and from 2.72 to 1.24 (p≤0.01), respectively; in Group 2, these dropped from 2.86 to 1.14 (p≤0.01) and from 2.95 to 1.24 (p≤0.01), respectively. Complete recovery from sensory problems occurred in 24 (69%) patients in Group 1 and in 25 (71%) patients in Group 2; their partial recovery was observed in 11 (31%) and 10 (29%) patients in these groups, respectively. One 1 month following decompression, the patients in Group 1 had more severe pain syndrome than those in Group 2; these differences became statistically insignificant after 6 months. The patients were found to be highly satisfied with surgical treatment. Permanent numbness, subjective weakness, thenar muscle atrophy, stage III CTS, and diabetes mellitus (DM) were predictors for less pronounced improvement in BCTQ scores after surgical treatment (p<0.05). The paper describes a clinical case that achieved full postoperative occupational and home rehabilitation. Conclusion. The patients with CTS were observed to have a marked reduction in pain and other neuropathic disorders just one month after surgical decompression and a substantial hand functional improvement following 6 months. The benefit from a minimally invasive access is less severe pain syndrome at 1 month after surgery. The predictors of less successful results of surgery are age (the older the patient is, the greater likelihood of having a worse result), permanent numbness, subjective hand weakness, thenar muscle atrophy, DM, and stage III CTS.

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.

In adult patients with rheumatoid arthritis (RA), mortality caused by respiratory infections is 2-5 times higher than in the population. One of the frequent infectious complications in the course of treatment with tocilizumab, the first-choice drug for treating systemic juvenile idiopathic arthritis (sJIA), is pneumonia characterized by a poor clinical picture, normal values of laboratory indices of the disease activity (ESR, C-reactive protein) with pronounced changes in the lungs revealed by computed tomography. In case of acute respiratory infection in children with systemic JIA, immunosuppressants and genetically engineered biological preparations (GEBP) are discontinued. This often leads to an exacerbation of the underlying disease and the progression of a pathological process. At present, vaccination against pneumococcal infection in Russia is not included in the standard for managing patients with rheumatic diseases. Studies of the safety and efficacy of vaccination with 13-valent pneumococcal conjugate vaccine (PCV) in patients with sJIA receiving genetically engineered biological preparations were not conducted. Clinical Case Description. The article shares the experience of vaccination of a girl aged 9 years with a 13-valent PCV that was conducted in the course of a scientific investigation, which studied the efficacy and safety of vaccination of children with systemic JIA prior to prescription of GEBP tocilizumab. Vaccination did not cause a deterioration in the course of the main disease (1 month), led to a reduction in the incidence of acute respiratory infections (from 4 to 1 time within 6 months before and after vaccination), and discontinuation of antibacterial drugs within 6 months after vaccination. Conclusion. The safety of a 13-valent PCV in a child with sJIA and a decrease of the incidence of respiratory diseases after vaccination, their complications, and the use of antibacterial drugs have been shown.

© 2018 Voprosy Sovremennoi Pediatrii - Current Pediatrics. All rights reserved. Background. Insufficient efficacy or intolerance of the first TNF-α inhibitor in patients with juvenile idiopathic arthritis (JIA) is an indication for the appointment of a second inhibitor. Golimumab is a new TNF-α inhibitor registered for treating JIA under pediatric indications. Clinical Case Description. At an early age, the patient had an onset of polyarticular JIA. Due to the aggressive and rapidly progressive course, failure of therapy with nonsteroidal anti-inflammatory drugs, methotrexate and glucocorticosteroids for intra-articular administration, infliximab was prescribed to the patient, with a positive effect. Subsequently, the patient developed a secondary resistance to infliximab, inflammatory changes in the joints relapsed; thus, a second TNF-α inhibitor (golimumab) was prescribed. In the course of therapy, pain and signs of arthritis in the patient were reversed, and the range of motion in the affected joints increased. After one year of therapy, JIA remission was ascertained. At the same time, the child was not administered oral glucocorticosteroids. The duration of remission of the joint syndrome was 5 years. Adverse events were not serious and did not constitute a basis for drug discontinuation. Conclusion. Switching to a second TNF-α inhibitor (golimumab) was effective in a patient with a secondary resistance to the first TNF-α inhibitor.

An important goal of treating patients with juvenile idiopathic arthritis (JIA) is to achieve the best quality of life associated with health. Objective. Our aim was to assess the impact of methotrexate plus etanercept therapy on the quality of life of patients with early and late JIA. Methods. The prospective study included patients with early and late JIA without systemic manifestations. The patients' quality of life was assessed with the help of questionnaires for children and parents: the Pediatric Quality of Life Inventory (PedsQL) Generic Core Scale, the Pediatric Quality of Life Inventory (PedsQL) Rheumatology Module, and the Health Utilities Index Mark 3 (HUI3). The quality of life was assessed prior to the therapy and after one, six, and 12 months of treatment. Results. 150 children with JIA aged 5.1 (2.0; 17.7) years; 50 children aged 4.0 (2.3-11.4) years in the group of etanercept monotherapy, 50 children aged 5.0 (3.2-9.0) years in the group of methotrexate monotherapy, and 50 children aged 9.9 (6.4-13.0) years in the group of methotrexate plus etanercept combination therapy. All groups showed low scores on all questionnaires before treatment, compared to healthy children. In the course of therapy, there was a tendency for score increase to almost 1.0 according to the HUI3 questionnaire in all groups. After one year of etanercept therapy, the parameters of the quality of life of children with early JIA did not differ from healthy children; the score increased from 56 to 90 p = 0.942 according to the physical functioning scale and from 60 to 85 p = 0.889 according to the emotional functioning scale. In the 2nd group, there was a tendency for score increase, but a statistically significant difference was found across all scales of the questionnaire. After 12 months of etanercept plus methotrexate combination therapy in patients with late JIA, the questionnaire analysis showed that the responses of healthy children and children with JIA differed with probability p = 0.001 for the physical functioning scale, p = 0.001 for the social functioning scale, p = 0.001 for role functioning, and p = 0.001 for the total score. The score increase from 60 to 85 p = 0.789 was noted for emotional functioning scales. Conclusion. The use of questionnaires to assess the quality of life in children with severe chronic diseases can significantly improve the efficacy of treatment and ensure its control.

© Group of authors, 2018. The article presents literature data on the methods of correction of linear atrophy of the skin (striae). This pathology is widespread in both sexes. The decline in the quality of life in this disease occurs largely due to the presence of a cosmetic defect. To date, there is no universal therapeutic approach for the correction of stretch marks. In this article available literature data on the problem of linear atrophy of the skin has been summarized.

Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is defined as an acute clinically significant respiratory deterioration characterized by evidence of new, widespread alveolar abnormalities, such as diffuse bilateral ground-glass opacification and/or consolidation, and the absence of other obvious clinical causes like fluid overload, left heart failure, or pulmonary embolism, etc. AE-IPF is subcategorized as “triggered” (where specific causes are identified, for example, infections, surgery procedures, drug toxicity, etc.) or “idiopathic” (where no specific causes are identified). In randomized trials, the annual incidence of AE-IPF is about 8%, in retrospective studies it reaches 19%. Severe forms of IPF are an important risk factor for the development of AE-IPF. In-hospital mortality from AE-IPF is more than 50%, and the average survival of patients with AE-IPF is 1-4 months. Currently, there remain no proven, effective therapies for AE-IPF. In real clinical practice patients with AE-IPF still receive high doses of systemic corticosteroids and antibiotics. Antifibrotic therapy can reduce the risk of exacerbations; it has been shown that therapy with nintedanib leads to a reduction in the number of confirmed/suspected AE-IPF by 68%. It is necessary to further study the potential methods of prevention and therapy of AE-IPF in future clinical trials.

In this article we have described clinical pharmacology and data of clinical studies of an innovational drug valsartan + sacubitril in patients with chronic heart failure (CHF). The use of supramolecular complex valsartan + sacubitril allows to elevate quality of life and improve prognosis of patients with CHF. High efficacy of valsartan+sacubitril relative to impact on composite primary end-point (cardiovascular death + hospitalization due to CHF) was demonstrated in the clinical trial PARADIGM-HF in which it was compared with angiotensin converting enzyme inhibitor enalapril. Advantages of the use of valsartan + sacubitril for the budget were demonstrated in pharmacoeconomic studies. These advantages are maximally realized at long-term administration. Cost-efficacy of the use of valsartan+sacubitril in pharmacotherapy of CHF is comparable with that of statins in the treatment of ischemic heart disease or implantation of a cardioverter-defibrillator in prevention of sudden cardiac death. Thus, introduction of the drug into practice can be expected to reduce budget expenditures.

Purpose: creation of working classification of morphologic variations of postoperative lens capsule opacity after Micro-Invasive cataract surgery. Material and methods: Morphologic study of the lens capsule (LC) has been conducted on 4 artiphakic cadaveric eyes. A specimen of an isolated anterior lens capsule, obtained during the repeated operation with changes characteristic for anterior capsular contraction syndrome has been studied too. The obtained specimens have been researched with the method of semithin sections. Results: The analysis of the morphologic cadaveric LC specimens revealed the polymorphism of secondary cataract (SC). Besides well known "classic" SC forms, which were caused by fibroplasias processes or pseudo-regeneration a new type of postoperative LC opacity not represented in the available literature before has been revealed. The given variant of opacities was called "pseudo-hyaloid" form and characterized by the absence of clear LC borders, changes of its normal structure, the appearance of loose fibrillar structure with microslit spaces and exfoliations, that possibly was the consequence of acustic cavitation, arising in the result of ultrasonic effect. As a result the LC lost characteristic for it the role of the dense bed and made impossible adhesion and migration on its changed surface the proliferative fibrocellular elements characteristic for "classic" SC forms. The microscopy results of the isolated anterior LC specimen in the area of capsulotomic aperture showed the presence of altered abundant loose fibrillar tissue with microporous structure and expressed forming of folds. Making layers of fibrous tissue exceeded the thickness of the normal anterior LC in 10 and more times and considerably reduced the diameter of capsulotomic aperture. Conclusion: The variety of postoperative LC opacities confirmed by the results of morphologic studies afforded to suggest a new working classification in which all possible morphologic variants and the stages of the secondary pathologic changes forming of anterior LC. The suggested classification is convenient for the understanding and must promote to make a right algorithm in the choice of optimal and safe technology of laser reconstructive interventions.

Objectives to enhance the morphological diagnostic complex in order to predict postoperative outcomes in a more accurate way and to optimize patients with non-muscular invasive bladder cancer treatment. Materials and methods. The study included 34 patients from 25 to 71 years old underwent laser en-block resection, the most of them were males - 28. In 9 cases multiple carcinomas (2 or more) were found. Huge tumors (2 cm or more in one dimension) were resected in 6 patients. Results. The major part of tumors removed (n = 22) histologically appeared to be papillary urothelial carcinomas with low grade of malignancy and PUNLMP; in 6 cases G2 was verified, one tumor with high malignancy potention - G3. In 3 patients intramuscular invasion was found (invasive carcinoma T2) excluding them from the study. Discussion. Laser en-block resection of non-muscle-invasive bladder cancer appears to be the most optimal approach in operative treatment that provides representative histological material. For correct morphological estimate we recommend either to expand the resection zone to 1 cm which allows to remove circular resection margin or to take extra pinch biopsy from tumor crater (vertical margin). In 3 patients from our study positive circular margin was revealed histologically whereas foci of perineural and perivascular invasion were found in one case. A new subgrading of stage T1 depending on intramuscular invasion depth was suggested whereas the main criteria is the muscularis mucosae involvement. Conclusion. Morphological estimate of circular resection margin provides an ability to predict postoperative outcomes and correct the treatment in one or another way. Subgrading for T1-stage tumors is recommended for following correct postoperative prognosis and possibility of tumor recurrence.

Pectus excavatum (PE) and pectus carinatum (PC) in children are the most common congenital deformities that cause complications in the thoracic organs; however, the role of chondrocytes and cartilage canals in the pathogenesis of these conditions remains unexplored. Objective — to investigate qualitative and quantitative changes of cartilage lacunae and canals in the costal cartilages in children with PE and PC compared to those with normal chests. Subject and methods. Costal cartilages were investigated in 10 children with normal chests (a control group), in 12 children with PE, and in 12 children with PC. Tissue fragments were fixed in 10% neutral formalin and embedded in compacted paraffin. Sections were stained with hematoxylin and eosin. Slides were examined by light microscopy. Cartilage lacunae, hyper-and hypolacunar zones, and cartilage canals were morphometrically examined, followed by statistical data analysis. Results. There was a significant decrease in the number of cartilage lacunae and in the frequency of hyperlacunar zones and an increase in that of hypolacunar zones in the PE and PC groups. There were no significant differences in these parameters between the PE and PC groups; however, there was a tendency to the smallest number of cartilage lacunae and canals in the PC group and that to the preponderance of empty lacunae in the PE group. Only the PC group showed also negative correlations between the proportions of empty lacunae and the age of children. Conclusion. The pathogenesis of PE and PC in children is related to the impaired trophism of costal cartilages due to the smaller number of cartilage channels containing vessels and lacunae with chondrocytes. The development of PE and PC is associated with specific costal cartilage morphological changes that suggest that PE and PC are different manifestations of the same disease, namely connective tissue dysplasia.

The aim of the study was to study the effect of orthognathic surgery using the developed method of correction of dentoalveolar anomalies on the shape of the nose in patients with Class III tooth-jaw anomalies, according to Engle's classification, combined with an increase and lengthening of the nose. In the period from 2014-2017 on the basis of FGBBO VO 'PIMU' of the Ministry of Health of Russia treated 45 patients with maxillofacial anomalies, among them 31 people diagnosed with upper retro microburnia, lower macrognathia, Engle III class, skeletal type. All patients were between the ages of 21 and 45, without severe co-morbidities. We evaluated the nasolabial angle (ÐCm-Sn-UL) characterizing the projection of the tip of the nose in patients with a skeletal form of mesial occlusion and an increase and extension of the tip of the nose before and after surgical treatment. According to the data of various authors, the value of the nasolabial angle in the norm varies from 97 to 110°. The mean nasolabial angle before the operation was 83.52±2.02°, which is much less than the recommended value, which indicates a pronounced elongation and 'droop' of the tip of the nose. The average value after the operation was 94, 90±1.88°, which on the average is 11° more than the initial data. These data indicate a change in the projection of the tip of the nose and an increase in the angle of Sm-Sn-UL, thereby improving the appearance of the patient.

Research objective was assessment of a possibility of primary diagnosis of viruses Epstein-Burr, a cytomegalovirus, a virus of herpes of the 6th type in oral liquid and also influences of herpes infection on development and the clinical course of precancer diseases of the oral mucosa and the red border of lips (RBL). Profound clinic-immunological examination is conducted to 60 patients: the first group are have made 20 patients with an erosive and ulcer form of the lichen planus, the second - 20 people with an erosive form of a leukoplakia, a third - 20 people without diseases of the oral mucosa. As a result of work detection herpes infection is revealed high (90%). The combined infection with a virus Epstein-Burr and a virus of herpes of the 6th type was observed more than at a half of patients. The imbalance of factors of local immunity of the oral cavity in the form of increase in the IgG profile, decrease in concentration of IGA, lysozyme, and increase in an indicator of Ksb three times in comparison with norm and also substantial increase of level of pro-inflammatory cytokin IL 1β and FNO-α is found in patients with precancer diseases of the oral mucosa. Characteristic clinical feature of the precancer diseases associated with latent herpes infection is the long, recidivous current, persistent to traditional therapy. The research of oral liquid and blood on herpes viruses and consultation of the infectiologist is recommended to all patients with precancer diseases.

The review of the literature deals with the participation of Clara cells now called club cells (CCs) of the epithelium in the respiratory and terminal bronchioles in the pathogenesis and morphogenesis of chronic inflammatory diseases, precancer, and cancer of the lung, which develop in the respiratory segments. The review summarizes data on the histophysiology of CCs and their participation in the pathogenesis and morphogenesis of chronic interstitial lung diseases, pneumoconiosis, chronic obstructive diseases, adenomatosis, and adenocarcinoma of the lung. In this area, there is a bronchioloalveolar junction area (BAJA), one of the most important stem cell niches. CCs are located in the BAJA; they are progenitor tissue stem cells and play an important role in the regeneration of the epithelium of the respiratory bronchioles and alveoli. Pathology of CCs in the BAJA leads to the maintenance of chronic inflammation, to the destruction of the lung elastic frame, and to impaired epithelial regeneration, interstitial fibrosis, and adenomatosis. In this case, decompensated inflammation, pathological regeneration, and fibrosis develop, which, along with the action of carcinogenic agents, can contribute to the accumulation of mutations and epigenetic rearrangements in the CCs, which subsequently results in atypical adenomatous hyperplasia and adenocarcinoma of the lung.

Traditionally, Parkinson's disease (PD) is associated with the lesion of the substantia nigra and dopamine system dysfunction. However, current studies show the involvement of other CNS regions, which extend far beyond the substantia nigra, in the pathogenesis of PD. The prevalence of altered α-synuclein in PD leads to the dysfunction of several neurotransmitter systems including the orexin system located in the hypothalamus. The involvement of this system in the neurodegenerative process explains some symptoms of PD including daily drowsiness and eating disorders. The authors consider the pathophysiology of the orexin system and its role in the pathogenesis of PD.

Aim: to value the significance of various predictors of sudden cardiac death (SCD) and clarify the selection criteria for implantation of cardioverter-defibrillators in patients with cardiomyopathies [dilated (DCM), arrhythmogenic right ventricular (ARVC), left ventricular noncompaction (LVNC)]. Material and methods. 220 patients with DCM syndrome were observed, 151 men, average age 47.5±12.5 years [mean left ventricular end-diastolic dimension (LV EDD) 6.5 [6.0, 7.1] cm, LV EF 30.3±10.1%], 50 patients with ARVC (definite diagnosis in 26 patients, probable in 13, possible in 11), 20 men, average age 38.1±14.6 years and 108 patients with a definite diagnosis of LVNC, 63 men, average age 45.4±14.8 years [mean LV ejection fraction (LF EV) 38.4±14.4%, LV EDD 5.9±0.8 cm]. The average follow-up periods were 16 [6, 37], 13.5 [4, 34] and 14 [3, 5, 36.0] months accordingly. The decision to implant the ICD / CRT-D was taken individually. The endpoints of the study were overall mortality, SCD, death + transplantation, appropriate defibrillators shocks and the "shocks + SCD". Results. The overall mortality in DCM, ARVC, and LVNC was 19.1%, 14.0% and 14.8%. It was mainly determined by terminal heart failure; SCD was recorded in 2.7%, 4.0% and 2.8%. Cardioverter-defibrillators were implanted in 66 (30%) patients with DCM (37 ICD, 29 CRT-D, 93.9% as the primary prevention of SCD), in 13 (26%) patients with ARVC (only ICD, primary prevention in 32,1%) and in 33 (30,6%) patients with LVNC (24 ICD, 9 CRTD, primary prevention in 88,1%). The frequency of appropriate shocks was 18.2% (15.0% in the primary prevention group and 50.0% in the secondary group) in patients with DCM syndrome, 69.2% (33.3% and 80.0% %) in ARVC, and 27.2% in LVNC (22.2% and 50.0%). The primary (genetic) nature of DCM (RR 1.58, OR 10.93), stable VT (RR 18, OR 26.5), and unstable VT (RR 1.43), a low QRS voltage (RR 1.75, OR 1.98), absence of LV hypertrophy signs on the ECG (RR 1.37, OR 2.56) were identified as criteria for selection for the implantation of a defibrillators in patients with DCM syndrome. In the patients with ARVC, these were a stable VT/VF and syncope (RR 4.75, OR 19), male sex (RR 1.25, OR 2), the low QRS voltage (RR 2.2, OR 10.5), chronic heart failure (OR 2.4, OR 8.0), the size of RV 2.85 cm (RR 1.55, OR 3.5), LV EDD> 5.5 cm (RR 2.1, OR 16, 7). In patients with LVNC the criteria were a stable VT/ VF, the presence of myocarditis (RR 3.3, OR 6.3), more than 500 PVBs per day (RR 3.3, OR 4.9), the low QRS voltage (RR 1,1, ОR 1,1), the follow up more than one year (RR 1,5, ОR 1,8). EF is not a statistically significant predictor of appropriate defibrillators shocks. Conclusions. In patients with various cardiomyopathies, which are accompanied by a high risk of SCD, the implantation of a cardioverter-defibrillators is an effective method of preventing SCD, including primary prevention. Due to adequate use of cardioverter-defibrillators in patients with DCM, ARVC and LVNC implanted in view of conventional and additional indications established in the study, mortality is determined primarily not by SCD, but terminal heart failure. Isolated myocarditis as the cause of DCM syndrome is not accompanied by a high risk of SCD, but its adherence to genetic cardiomyopathy determines the high risk of SCD.

Despite years of experience gained in studying hypertension, the problems concerning selection of antihypertensive therapy with pleiotropic organ-protecting effects are still of current importance. The purpose of the study was to assess therapeutic efficacy and pleiotropic organ-protective capability of third-generation calcium antagonist lercanidipine in patients with stage 2-3 hypertension. Method: Our study enrolled a total of ninety-two 31-to-84-year-old patients. Of these, 72 patients diagnosed as having stage 2 or 3 AH composed the Study Group and 20 apparently healthy subjects were included into the Control Group. At baseline and after 6 months, all patients of the Study Group underwent examinations consisting in measuring biochemical parameters [total cholesterol (TCH), triglycerides (TG), low-density lipoprotein cholesterol (LDL CH), uric acid, urea, creatinine, glucose], 24-hour ambulatory BP monitoring, echocardiography (EchoCG) in order to assess the dimensions and volume of the cardiac chambers, thickness of the left ventricular posterior wall (LVPW) and left-ventricular myocardium mass index (LVMMI), studying microalbuminuria (MAU), a known marker of endothelial dysfunction and early renal lesion; assessing the state of the vascular wall by the ankle-brachial index (ABI) and pulse pressure (PP). Antihypertensive therapy consisted in lercanidipine alone taken at a dose of 10-20 mg/day, failure to thereby achieve the target BP level was followed by additionally prescribing an angiotensin converting enzyme (ACE) inhibitor, enalapril, given at a dose of 5-20 mg twice daily. Results: All patients by the end of the study achieved the target level of AP (p<0.05), also demonstrating significantly improved (p<0.01) parameters of endothelial dysfunction and an early marker of renal damage (MAU), indices of elastic properties of the vascular wall ABI (p<0.05) and PP (p=0.01). Significantly positive dynamics was observed for the following parameters: decreased creatinine concentration (p<0.001), increased GFR (p<0.001), decreased levels of TCH (p<0.01) and LDL CH (p<0.001). Conclusion: Lercanidipine therapy of patients with stage 2-3 AH proved highly efficient, well tolerated, metabolically neutral with pleiotropic organ-protecting properties in the form of improved condition of the vascular wall, correction of endothelial dysfunction, nephroprotective action.

© 2018 by the authors; licensee Modestum Ltd., UK. Objective: Prolongation of the QT interval in patients with coronary heart disease (CAD) is a risk factor of polymorphic ventricular tachycardia (PVT) and as consequence, the sudden death. Drug-drug interactions (DDI) on metabolic rate involving cytochrome P-450 (CYP) is the one of the major cause of Long QT Syndrome (LQTS). The aim of the present study was to improve the safety of combined pharmacotherapy when using drugs that affect the QT interval. Method and Results: Medication occurrence of potential dangerous combination of medicines that are affected on QT interval duration in patients with CAD are researched (outpatient medical records (patient history) analysis). Clinical relevance of DDI, which are associated with changes in CYP enzyme activity, categorized by drugs.com Medication Guide. Finding potential dangerous combination of medicines that are affected on QT interval duration were administered to patients with CAD in 3.6% cases in outpatient clinical practice. The most often prescribed combination of drugs is amiodarone and torasemide (13.3% evidence of all concomitant administration that are leading to QT prolongation). The potential mechanism of Amiodarone and Torasemide interaction on metabolic rate that are leading to QT prolongation are competitive substrates CYP 2C8 and a result of inhibited CYP 2C9 by amiodarone. Conclusion: Ability to predict the prolongation of the QT interval caused by DDI on metabolic rate make possible to improve the safety concomitant administration to patients with CAD.

Problem of internal carotid artery disease diagnosis appears to be crucial today. Complications of this pathology are strokes and transient ischemic attacks. There is no technology for their prediction or at least stratifying risks. Some recent researches are devoted to a new diagnostic method. This new technology is called Contrast Enhanced Ultrasonography (CEUS) and followed by outstanding results in studying the morphological peculiarities of internal carotid artery plaques and predicting the probability of complications. CEUS is a new way for atherosclerotic process analysis because it is able to detect intraplaque neovascularization and vascular wall inflammation.

© 2018. Conjugates of Streptococcus pneumoniae type 9N capsular polysaccharide with tetanus toxoid have been prepared. Their interactions with specific antibodies to tetanus toxoid and polysaccharide 9N were assessed, which permitted to select a conjugate with the optimal ratio of the polysaccharide and carrier protein (3:4). The parameters of the efficient adsorption of tetanus toxoid and polysaccharide on aluminum hydroxide for the following in vivo experiments were determined using the quantitative ELISA; in particular, the optimum ratio of the conjugate and adjuvant was proved be ≤ 1:1 (w/w). The repetitive immunization with the selected conjugate adsorbed on aluminum hydroxide increased the anti-PS antibody titers up to 70400 (p < 0,001) which is 140-fold higher as compared to the antigen unconjugated form. The investigation of the antibody protection from Streptococcus pneumoniae 9N after the intranasal challenge of wild-type mice revealed that the titer of the bacterial contamination in the immunized mouse lung tissue was 10-fold lower than that in non-immune mice 72 h after the contamination (p > 0,05).
