Aim: to assess the prevalence of bendopnea and association of this symptom with clinical, laboratory and echocardiographic features, clinical outcomes during 2 years of followup in ambulatory elderly patients with chronic heart failure (CHF). Materials and methods. We conducted an open, prospective, nonrandomized study of 80 ambulatory patients aged ≥60 years admitted with heart failure II-IV NYHA class CHF. Baseline survey included physical examination, estimation of Charlson comorbidity index, echocardiography and laboratory tests. Bendopnea was considered when shortness of breath occurred within 30 sec of sitting on a chair and bending forward. Mean followup was 26.6±11.0 months. Results. Bendopnea was present in 38.8% patients. All these patients complained of shortness of breath during physical exertion and 45.2% of them had orthopnea. Bendopnea was associated with the male gender (odds ratio [OR] 11.8, 95% confidence interval [CI] 4.04-34.8, p<0.001), severity of the clinical status (ШОКС [shocks] scale score) (OR 1.78, 95% CI 1.29-2.38, p<0.001), Charlson comorbidity index (OR 1.29, 95% CI 1.07-1.52, p=0.007), coronary heart disease (OR 26.6, 95% CI 3.34-21.3, p=0.002), history of myocardial infarction (OR 13.9, 95% CI 4.2-46.6, p<0.001), left ventricular (LV) aneurysm (OR 13.3, 95% CI 2.69-65.9, p=0.002), increased indexed LV endsystolic diameter (OR 8.2, 95% CI 1.9-34.1, p=0.004), left atrial size (OR 4.3, 95% CI 1,4-12.5, p=0.008), indexed LV endsystolic volume (OR 1.32, 95% CI 1.07-1.64, p=0.010), pulmonary artery systolic pressure (OR 1.26, 95% 1.03-1.45, p=0.002), high levels of NTproBNP (OR 1.0, 95% CI 1.0-1.002, p=0.055), creatinine (OR 1.04, 95% CI 1.02-1.07, p=0.001), uric acid (OR 1.006, 95% CI 1.002-1.011, p=0.004); hospitalizations (OR 7.61, 95% 2.04-28.4, p=0.003), and patient's mortality (OR 5.63, 95% CI 1.94-16.4, p=0.001). Multifactorial analysis confirmed association of bendopnea with severity of clinical status (OR 1.70, 95% CI 1.04-2.8, p=0.033), increased left atrial size (OR 5.67, 95% CI 2.75-21.32, p=0.029) and Charlson comorbidity index (OR 1.17, 95% CI 1.04-2.80, p=0.050). During followup 51.6 and 12.2% of patients died among those with and without bendopnea, respectively (OR 4.22, 95% CI 1.85-9.9, p<0.001). Conclusion. Bendopnea is associated with an adverse hemodynamic profile and prognosis, what allows to consider this symptom as a reliable marker of CHF severity.

To study the efficacy of plasmapheresis as the main type of pathogenic treatment or in combination with immunosuppressive therapy in patients with dilated cardiomyopathy (DCMP) and arrhythmias of immune-inflammatory nature. Material and methods. The main group included 20 patients with arrhythmic myocarditis (with premature supraventricular / ventricular contraction >3000/day, n=3/8, atrial fibrillation (AF) n=9) and 14 patients with DCMP syndrome (enddiastolic volume (EDV) left ventricle (LV) 6,3±0,6 cm, ejection fraction (EF) 33,5±8,1%). The inclusion criterion was an increase of at least 2 types of anti-cardiac antibodies titers ≥ twice. Myocarditis is diagnosed using myocardial biopsy, magnetic resonance imaging, multispiral computed tomography, scintigraphy, coronary angiography. We used a course of discrete plasmapheresis. The comparison group included 26 patients with an arrhythmic myocarditis and 19 with DCMP syndrome (EDV 6,6±0,8 cm, EF 32,6±7,3%), which plasmapheresis was not used. Dynamics was assessed at 6 and 12 months. Results. In groups of patients with arrhythmias and DCMP, a significant decrease in anti-cardiac antibodies titers was observed immediately after plasmapheresis and in control studies (p<0,05). In patients with arrhythmias, a health-promoting effect (a decrease in the number of premature contraction and a frequency of atrial fibrillation ≥75%) was observed in 65% of the main group and 58% of the comparison group. Predictor of plasmapheresis efficiency was a titer of specific antinuclear factor ≥1: 40 (sensitivity — 92,3%, specificity — 71,4%, AUC — 0,813, p<0,05). Methylprednisolone was prescribed to 45% of patients in the main group and 73% to patients in the comparison group (p>0,05) at a dose of 8 [4; 16] and 16 [10; 24] mg per day, respectively, p>0,05. In patients with DCMP in the main group, a significant increase in EF (p<0,05) (up to 41,4±8,2% and 46,3±12,7% vs 39,1±13,7% and 37,2±10,7% in the comparison group) and the distance of 6-minute walking test was obtained. A good effect (increase in EF by 10% or more) was noted in 50% of the main group and 32% of the comparison group. The predictor of plasmapheresis efficacy was systolic pressure in the pulmonary artery ≥28,5 mm Hg. (sensitivity — 100%, specificity — 71,4%, AUC — 0,893, p<0,05). In the main group, methylprednisolone was assigned to 43% of patients, in the comparison group — 89%, p<0,05. The average doses of methylprednisolone in the main group were significantly lower than in the comparison group (8 [8; 17,25] vs 16 [13; 28] mg per day, p<0,05). Conclusion. Positive clinical response to plasmapheresis was noted in 65% of patients with arrhythmias and in 50% of patients with DCMP of immune-inflammatory nature. In patients with different types of myocarditis, plasmapheresis increases the efficacy of antiarrhythmic and immunosuppressive therapy.

Purpose: To assess effectiveness of algorithms of minimization of right ventricular pacing (MRVP) for prevention of progression of atrial fibrillation (AF), lowering of frequency of hospitalizations due to cardiovascular causes, and mortality in patients with sick sinus syndrome (SSS) and history of paroxysmal AF compared with standard compared with dual-chamber pacing (DDDR). Materials and methods. We included in this single-center prospective study 74 consecutive patients with indications to permanent DDDR pacing because of SSS combined with documented history of paroxysmal AF. Patients were randomized in the groups of DDDR pacing (n=3 6) and with activated algorithms of MRVP (n=38). Pacemaker check up was made after 6 months during I year after device implantation. Primary composite endpoint included development of persistent AF, hospitalization due to cardiovascular causes, and all cause death. Results. During follow-up there was no statistically significant difference in achievement of the primary endpoint (27.8 and 18.4% in groups of DDDR pacing and activated algorithms of MRVP respectively (relative risk 1.29% confidence interval 0.43 to 3.86; p=0.25). Rate of development of persistent AF in both groups was comparable (8.6 and 5.3% in DDDR and MRVP groups, re-spectively; p=0.47). Median AF burden was 6.0 (0;42) and 6.0 (0;42) min/day in DDDR and MRVP groups, respectively (p=0.67). Conclusion. Our study failed to demonstrate advantages of the use of algorithms of decreasing "unmotivated" right ventricular pacing over standard regimen of standard DDDR pacing in patients with SSS and history of paroxysmal AF.

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.

Urinary disorders in women with recurrent urinary tract infections (UTI) are a serious problem that has not yet been solved despite that there are a large number of papers on this topic. Pregnant women who have experienced acute urinary tract infection and those who have been treated for asymptomatic bacteriuria should be followed up until delivery, by examining their urine to prove the efficiency of antibacterial therapy that can threaten their pregnancy. It is necessary to emphasize the importance of prevention, timely detection of signs of UTI in pregnant women and the correct choice of antibiotic therapy in the developed UTI.

© 2018, Media Sphera Publishing Group. All rights reserved. This article was designed as a comparative review of the literature publications pertaining to the two opposite approaches to the surgical treatment of varicose veins of the lower extremities based on the vein-sparing and radical principles. We compare classical phlebectomy (i.e. endovenous treatment of varicose veins including thermal obliteration) and the vein-savings treatment with the use of the methods for the hemodynamic correction of venous insufficiency, such as ASVAL, CHIVA, and short stripping with special reference to its location and extent. Also covered in the article is the issue of the appropriate length of great saphenous vein stripping. The authors emphasize that it should be based on the extent of reflux rather than on the desire to avoid saphenous nerve injury. It is maintained that either partial or complete preservation of the stem of the great saphenous vein (GSV) in addition to the endovenous obliteration techniques is an efficient and safe modification of the surgical intervention. Stripping is indicated when the endovasal intervention is either impossible or undesirable because of clinical, anatomical, and/or technical limitations. Short stripping in the absence of total reflux in the great saphenous vein is a safer procedure in comparison with the total extirpation of the venous stem.

© 2018 Ismailova et al. Orbital decompression is a surgical procedure aimed at increasing the orbital volume and/or decreasing the volume of the orbital fat. The indications for orbital decompression are determined in the course of thorough eye examination. An important objective of examination of a patient with thyroid eye disease (TED) is determination of inflammation activity and severity. Orbital decompression is a surgical procedure that can be performed in both the active and non-active stages of the disease. However, the indications for the surgery in these cases are different. Optic neuropathy and severe corneal disease are threatening complications that may lead to permanent visual loss and generally occur in the presence of active orbital inflammation. If treatment with high-dose corticosteroids has proven ineffective, an urgent surgical procedure consisting of orbital decompression and, in case of involvement of the cornea, eyelid and corneal surgery has to be performed. Owing to significant progress in technology, improvement of methods and accumulated experience over the past decade, the indications for bone orbital decompression have extended compared to the time when this procedure was used only in patients with extremely severe TED. The most common complication of the orbital decompression is the development or deterioration of previously existing binocular diplopia and strabismus. In addition, other parameters may change as well, including the position of the globe, the eyelids, the angle of deviation of the eye, and intraocular pressure. Thus, bone orbital decompression is a major step of a comprehensive, often multistage, system of rehabilitation of patients with severe refractory TED.

The stability of the expression of reference genes varied depending of the cells type and chemical structure of nanoparticles. The level of YWHAZ mRNA after exposure by nanoparticles demonstrated highest stability in lymphocytes, neutrophils, and monocytes. Stability of YWHAZ expression was confirmed by Western blotting. Our findings suggest that YWHAZ is the most suitable as the reference gene.

PURPOSE: To analyze the condition of the lacrimal gland in patients confirmed to have sarcoidosis. MATERIAL AND METHODS: The study included 46 patients (92 orbits) with verified diagnosis of systemic sarcoidosis that were examined during the period of 2009 to 2014. The age of patients ranged from 23 to 65 years and the average was 45.1 years. Among the examined patients, 66% were female and 34% male. In all patients, the diagnosis was verified according to modern criteria. RESULTS: Acoustic structure of 46 lacrimal glands of patients with systemic sarcoidosis (92 orbit), and lacrimal glands of 30 healthy individuals (60 orbits) were examined. In-depth in vivo examination of morphological changes was done using 'advanced' analysis of three-dimensional images. CONCLUSION: The analysis of a large number of studies devoted to changes in the lacrimal glands caused by sarcoidosis revealed a difficult problem: are there any differences between isolated involvement of the lacrimal gland tissue and the defeat of various organs and tissues? For now, the question remains unanswered.

Materials and methods. In the blood of 50 patients with DM and 25 patients without disorders of carbohydrate metabolism were estimated: the level of oxidized low-density lipoprotein (oxLDL) by immunochemical method, the content of SH-groups in plasma proteins, the activity of Cu, Zn-superoxide dismutase (SOD) in erythrocytes, the length of telomere in leukocyte DNA, the level of 8-hydroxy-2'-deoxy-gunosine (8-oxo-dG) in plasma and urine. Results and discussion. It is shown that in DM patients the level of oxLDL increases and the content of SH-groups in proteins and peptides of the blood plasma decreases, which indicates the development of oxidative stress. In addition, a carbonyl-dependent modification of erythrocyte SOD was detected in DM patients, as well as oxidative DNA destruction (decrease in telomere length in leukocytes and an increase in the level of 8-oxo-dG in blood plasma and urine). Conclusion. On the basis of the definition of a complex of correct indicators, a multiple oxidative modification of biopolymers of blood (proteins and DNA) was detected in patients with DM.

Materials and methods. The analysis of falciparum malaria cases with deaths recorded in Russian Federation from 2013 to 2017 was conducted. The results of optimization of pathogenetic therapy of severe forms of falciparum malaria for the prevention of adverse outcomes in the intensive care unit of the Infectious Clinical Hospital №2 of Moscow in 44 patients with severe course are presented. Treatment, clinical laboratory and instrumental investigations were carried out in accordance with our intensive care protocol, which took into account the current WHO recommendations. Results. From 2013 to 2017 there were nine deaths from falciparum malaria reported in patients from African countries (6) and India (3). In Russia, due to the lack of effective drugs of artemisinin group, quinine with tetracycline or doxycycline is used for etiotropic therapy of patients with complicated form of falciparum malaria. In the management of such patients, the basis for treatment was the prevention of is-chemic, reperfusion injuries of organs and hemorrhagic complications. In the infectious clinical hospital №2 of Moscow, since 2007, the intensive care unit has developed and tested a protocol for intensive therapy in patients with severe and complicated forms of falciparum malaria, including preventive methods of extracorporeal hemocorrection with prolonged veno-venous hemodiafiltration therapy and plasmapheresis, as a result of which the mortality rate decreased from 84 to 6.8% Conclusion. The country's lack of anti-malarial drugs, the insufficient awareness of the population about the risk of infection and measures to prevent malaria, late referral of cases for medical care and errors of clinical diagnosis and treatment annually lead to fatal outcomes. In such situation, the experience of optimizing the treatment of severe falciparum malaria is particularly useful, allowing decreasing the mortality.

Objective: to study changes of acute-phase reactants (erythrocyte sedimentation rate – ESR, C-reactive protein – CRP), autoantibodies (IgM/IgA rheumatoid factors – RF, anti-citrullinated protein antibodies), immunoglobulin classes G, M, and A, and CD19+ B-lymphocytes in patients with rheumatoid arthritis (RA) 12 and 24 weeks after initiation of therapy with a rituximab (RTM) biosimilar at a total dose of 1200 mg. Subjects and methods. Examinations were made in 20 patients with a reliable diagnosis of RA (including 18 women; median age, 61.5 [54; 66.5] years; disease duration, 39.5 [20; 84] years; DAS28, 5.6 [4.9; 6.8]). All the patients received two intravenous infusions of RTM (Acellbia®) 600 mg at a 2-week interval during therapy with methotrexate, nonsteroidal anti-inflammatory drugs, and glucocorticoids. Clinical and laboratory parameters were analyzed immediately before therapy and then 12 and 24 weeks after the first infusion of the drug. Results and discussion. DAS28, ESR, and CRP level in respondents significantly decreased 12 and 24 weeks after RTM administration. The serum IgM RF concentration in the respondents was found to be significantly reduced at weeks 12 and 24 and amounted to 79.7 and 87.1% of baseline, respectively. The IgA RF level significantly decreased by 72 and 85% of baseline at weeks 12 and 24 of RTM therapy, respectively, in patients with a good response, and by 59.7 and 67.5% at weeks 12 and 24 in patients with a satisfactory response. The serum concentration of anti-cyclic citrullinated peptide antibodies in the respondents remained high throughout the follow-up. All the patients achieved CD19+ B-cell depletion at week 12 of therapy (absolute levels, 0); there was an increase in the level of CD19+ B-lymphocytes at week 24 (0.0030 [0.0003; 0.0270] 109/l). In both in the good and satisfactory response groups, the mean immunoglobulin levels remained within normal limits. Conclusion. The analysis of the efficiency of two infusions of the RTM biosimilar at a total dose of 1200 mg following 24 weeks of therapy initiation suggests that the drug is able to cause reductions in disease activity, laboratory signs of inflammatory activity, autoantibody concentrations, and complete B-lymphocyte depletion.

© 2018 Ima-Press Publishing House.All right reserved. Impaired B-cell immunological tolerance plays a central role in the pathogenesis of autoimmune rheumatic diseases and autoimmune diseases of another nature. B-cells link innate and acquired immunity: they express Toll-like receptors that respond to danger signals; act as antigen-presenting cells; induce an antigen-specific immune response; determine the development of immunological memory; and synthesize a wide range of cytokines that regulate (stimulate or suppress) an immune response and inflammation. In autoimmune diseases, there are metabolic and B-cellular signaling disturbances that lead to defects in B-regulatory, T-regulatory, follicular T-helper, and dendritic cells. B-cells synthesize organ-nonspecific and organ-specific autoantibodies that are biomarkers for autoimmune diseases and play an important role in their immunopathogenesis. Anti-B-cell therapy that causes B-cell depletion in blood and target organs is effective in a wide range of autoimmune diseases. Its efficiency is determined by various mechanisms, such as suppression of pathogenic autoantibody synthesis; modulation of the function of B-cells (antigen presentation, cytokine synthesis, and costimulation), T-lymphocytes and dendritic cells. Further study of a strategy for targeted anti-B-cell therapy, mechanisms of action, and new targets is important for the progress of modern rheumatology to improve the treatment strategy of autoimmune rheumatic diseases.

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.

Preoperative anemia is common in clinical practice, particularly in women of reproductive age, and it worsens the outcomes of operative treatment. Red blood cell hemotransfusions can be used for management of anemia developing in the perioperative period, however, they have only a short-term effect and can lead to serious complications. Introduction of blood saving strategies can prevent the development and progression of perioperative anemia and hence avoid hemotransfusions. The review considers modern perioperative blood saving strategies based on recent guidelines of the European and American societies of anesthesiologists.

© Bionika Media Ltd. Objective. To investigate whether early endometrial cancer can be treated and whether fertility can be preserved in young women, by using a hormonal combination: levonorgestrel intrauterine hormonal system (LNG-IUS; Mirena 52 mg of LH) and gonadotropin-releasing hormone agonists (Zoladex 3.6 mg). Subjects and methods. The investigation covered 79 patients. The case histories of 37 patients with atypical hyperplasia and 42 with stage IA (T1aNxMo) endometrial cancer were analyzed. The patients’ mean age was 33 years. The investigation was conducted at the Academician V.I. Kulakov National Medical Research Center of Obstetrics, Gynecology, and Perinatology, Ministry of Health of the Russian Federation. Results. Primary treatment was completed in 67 (84.8%) patients and in 12 (15.2%) during hormonal treatment. After completion of special treatment, 8 (11.9%) of the 67 women had 10 pregnancies that resulted in childbirth and spontaneous miscarriage in 8 and 2 cases, respectively. Recurrences and incurable disease were stated in 3 (4.2%) and 9 (12.8%) cases, respectively. Repeated hormone therapy cycles were not performed because the patients had refused organ-sparing treatment. All the 12 (17.1%) patients were successfully operated on. Conclusion. The proposed treatment regimen is a highly effective medical treatment in patients with precancer and early endometrial cancer. Independent hormone therapy is undoubtedly the best alternative to hysterectomy today in this group of patients who want to preserve reproductive function.

A quantitative analysis of the levels of environmental contaminants from the class of polychlorinated diben-zoparadioxins, furans (PCDD/F) and polychlorinated biphenyls (PCB) as sensors of chemical alteration in the reproductive system in idiopathic infertility. Patients and methods. The examination included 122 women diagnosed with «idiopathic infertility». The levels of ecopollutants were determined by a combination of high-performance capillary gas chromatography and high-resolution gas chromatography/ mass spectrometry according to the standard protocol. Results. In follicular fluid of patients, the total content of dioxins/furans did not exceed 15.7 pg/g of lipids, i.e. was at the sensitivity threshold of the employed method. PCB concentrations were also low (not more than 28.6 pg/g of lipids), but PCB153 and PCB180 congeners associated with fertility disorders have not been found. Conclusion. As has been hypothesized, this class of xenobiotics does not play a leading role in the genesis of environmentally-conditioned reproductive pathologies in women.
