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.

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.

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.

© 2018 Stolichnaya Izdatelskaya Kompaniya. Hypertensive heart disease with biventricular cardiac failure is not common in clinical practice. This diagnosis requires an extensive diagnostic search. We present the clinical case of the male patient of 38 aged. He was admitted to the clinic with heart failure 3-4 NYHA class. EchoCG revealed symmetric hypertrophy of the left ventricle up to 18 mm without its dilatation, a decrease in ejection fraction up to 42%, restrictive hemodynamics, overload of the right chambers, severe pulmonary hypertension (60 mm Hg). The clinical status included persistent arterial hypertension (180-220 and 120-150 mm Hg), effusion in both pleural cavities and pericardium, ascites, renal failure. During examination (multispiral computed tomography, magnetic resonance imaging, scintigraphy with 131I-MIBG), bladder paraganglioma was diagnosed (normatenafrin 1468 μg/day). The resection of the tumor was performed, according to immunohistochemical research - neuroendocrine carcinoma, G1. After 3 months a partial regression of hypertension and cardiac failure was observed with the preservation of a high level of creatinine. The criteria and differential diagnosis of the hypertensive heart disease and the syndrome of primary myocardial hypertrophy, diagnostics of the urinary bladder paraganglioma, complex mechanisms of myocardial damage within the pheochromocytoma and its prognosis are discussed..

© 2018 Stolichnaya Izdatelskaya Kompaniya. Acute myocardial infarction (AMI) is one of the main causes of morbidity and mortality, both in the Russian Federation and around the world. Approximately, in up to 10% of patients with clinical diagnostic features of AMI, early angiography does not reveal an occluded vessel or possibly any evidence of coronary artery disease. These patients constitute an intriguing subgroup referred to as "Myocardial Infarction with Non-Obstructive Coronary Arteries" (MINOCA). MINOCA is a collective concept that unites many different pathologies, which determines the essential heterogeneity of the etiological factors. Coronary artery embolism is recognized as an important non-atherosclerotic cause of AMI. In turn, the most common underlying disease in those with coronary embolism is the atrial fibrillation. The advantages of reperfusion strategy and cardioprotective therapy in the treatment of obstructive arteriosclerosis are well studied, widely presented in the literature and supported by a strong evidence base, while the issues of diagnosis and treatment of patients with MINOCA are currently widely discussed We present two clinical cases of embolic myocardial infarction in patients with atrial fibrillation, diagnosed in our clinic in 2017..

Acute experimental hepatitis was induced by acetaminophen administration of 1000 mg/kg. Studies were conducted in white Wistar rats. The aqueous extract of C. jubata demonstrated the hepatoprotective effect, comparable to that of the reference preparation "Carcil". This was manifested by the normalization of biochemical blood parameters (ALT, AST, alkaline phosphatase, cholesterol, total bilirubin) and antioxidant activity of liver homogenates, determined by the method based on oxidation of luminol induced by 2,2-azo-bis-2-amidinopropane. Normalization of morphofunctional indices was also shown in a histological study of liver of rats that received aqueous extract from C. jubata.

The anterior capsular contraction syndrome (ACCS) in pseudophakic patients is known to be accompanied by postoperative opacity of anterior lens capsule (ALC) and partial or full closure of anterior capsulotomy opening. Purpose: to perform complex morphological assessment of ALC in patients with ACCS. Material and methods. The study involved complex analysis of ALC that was removed due to ACCS in the pseudophakic eye in the setting of diabetes mellitus and past vitreoretinal surgery. The following examination methods were used: light-optical microscopy of ALC samples in the form of polychrome-colored semifine sections using optical microscope Leica DM-2500 (Germany), scanning microscopy of ALC surface with EVO LS10 (Carl Zeiss, Germany) microscope, analysis of chemical element composition and its variation of the ALC sample with energy-dispersive spectrometer Oxford X-Max50 (Oxford, UK). Results. Light-optical microscopy showed altered state and plication of ALC induced by proliferation from inner surface of the fibrocellular tissue, which gradually thickens (up to 360 µm) towards center and causes reduction of anterior capsulotomy opening. Scanning electron microscopy revealed presence of tissue with uneven micro-relief and a porous three-dimensional structure uncharacteristic for capsule on the surface of ALC. Thickness of the fibrous deposition significantly exceeded the thickness of ALC. Evaluation of elemental composition of the fibrocellular tissue showed elevated concentration of sulfur and phosphorus, which indicates high activity of the regenerative process. In the observed case, the regenerative process was of substitute nature because an attempt to restore the lens was accompanied by formation of connective tissue structurally different from original. Conclusion. Complex assessment of an isolated ALC sample allowed revelation of the chain of pathological processes accompanying the development of ACCS.

© 2018 SPIE. In this work, tissue-engineered structures based on a matrix of protein conjugates, chitosan and carbon nanotubes were prepared and studied. Bovine serum albumin (BSA), bovine collagen (BCrossed D sign¡) were used. Two types of single-walled carbon nanotubes (SWCNTs) were used to form a strong internal scaffold in a protein-chitosan matrix under the action of laser radiation. Tissue-engineered structures were created by means of layered deposition and laser evaporation of the initial aqueous dispersion from SWCNT, BSA, BC and chitosan succinate. As sources of laser radiation, a continuous diode laser with a wavelength of 810 nm and a pulsed fiber laser with a wavelength of 1064 nm and frequency of 80 kHz were used. Studies of tissue-engineered structures were carried out using vibrational spectroscopy methods (IR and Raman). The changes in the frequencies and intensities of the corresponding absorption bands and Raman lines of the amide group oscillations were analyzed. IR spectra of tissue-engineered structures demonstrated a high degree of binding of organic (protein, chitosan) and inorganic (SWCNT) components. The structure and defectiveness of the carbon nanotube scaffold were investigated in the Raman spectra.

Ependymoma is a central nervous system tumor that grows from ependymal cells lining the cerebral ventricles, central canal of the spinal cord, and filum terminale. Regardless of the histological type of ependymomas, they rarely have exophytic growth. Because of an extremely low occurrence rate of this phenomenon, we present two clinical cases of patients with classical intramedullary ependymomas (Grade II) having an extramedullary component. Material and methods. The paper presents two clinical cases of patients with intramedullary-extramedullary ependymomas of the spinal cord. The surgical technique is described. After surgical treatment, the performance status of patients remained unchanged. Conclusion. Radical removal of complex ependymomas provides conditions for long-term disease-free survival and further neurological recovery.

Immunosuppressive therapy aimed at the prevention of acute allograft rejection is the cornerstone of post-transplant management. In addition to its direct effects, immunosuppressive therapy is also involved in the generation of a number of post-transplant morbidities that limit the long-term outcome of heart transplant recipients. Given these data it appears that the individual tailoring of immunosuppressive therapy is of paramount importance in determining the outcome of heart transplantation. The goal of immunosuppressive therapy is to prevent rejection of the transplanted heart, while minimizing drug-related effects, such as infection, malignancy, diabetes, hypertension, and renal insuffi ciency. This review aimed is to analyze the protocols for the appointment of immunosuppressive therapy in various groups of recipients after heart transplantation.

The review discusses the role of blood pressure variability as a novel risk factor and its prognostic value in hypertension associated with the coronary artery disease. We discuss the modern approaches to calculation of blood pressure variability, its classification. The choice of antihypertensive drugs based on the blood pressure variability is discussed considering hypertension associated with coronary artery disease. We pay special attention to angiotensin enzyme converting inhibitors and calcium channel blockers, as well as their combinations. We present the evidence of the effects of perindopril and amlodipine and their fixed combination on the blood pressure variability and the decrease in cardiovascular risk in hypertension associated with coronary artery disease.

© Russian Journal of Cardiology. Arterial hypertension (AH) remains one of the most prevalent cardiovascular disorder in the world, as one of the main risk factors of myocardial infarction and stroke development. Monotherapy of AH is effective in no more than one half of patients even with moderate increase of blood pressure. Combinational antihypertension treatment does influence pathogenetic mechanisms of AH being an optimal solution. It is worthful to apply a fixed combination of telmisartan and hydrochlorothiazide. Such combination provides additional antihypertensive effect with more significant decrease of blood pressure than for the components separately. Also it is protective for organs and tissues that makes it to prescribe such combination to a broad range of patients.

© The European Society of Cardiology 2017. Aims: To evaluate safety and efficacy of moderate intensity interval exercise training early after heart failure decompensation on exercise tolerance and health-related quality of life (HRQoL). Methods and results: This is a prospective randomized controlled study. We screened 234 consecutive patients admitted with decompensated heart failure; 46 patients (42 men/4 women; 61±12 years of age) were randomized to a moderate intensity aerobic interval training (n = 24) or to a control group (n = 22). Patients underwent cardiopulmonary exercise testing, echocardiography and Minnesota Living with Heart Failure questionnaire (MLHFQ) at baseline, after three weeks and after three months. After three weeks, peak-VO2 increased by 17% in the training group (p = 0.003) with further increase by 10% after three months (p < 0.001) but did not change significantly in controls. MLHFQ score improved after three weeks, with better results in the training group (from 64.6±15.6 to 30.8±12.9, p < 0.001). After three months, MLHFQ further improved in the exercise training group, but not in controls. Left ventricular ejection fraction was not significantly different between the two groups at baseline and after three months. No serious adverse events related to exercise testing or training wssere observed. Conclusions: Interval exercise training early after an episode of heart failure decompensation is safe and effective in improving exercise tolerance and health-related quality of life in selected patients after achievement of clinical stability. Positive effects remained sustained after three months. Further studies are needed to define role and indications for interval exercise training early after heart failure decompensation.

Authors present a case-report of a 36-year-old patient with pain syndrome in the face region (craniomandibular dysfunction with occlusive disorders) involving pericranial muscles and shoulder girdle muscles. Thioctic acid was prescribed as a basic therapy, and relaxation tire, mimic gymnastics, post-isometric relaxation, vitamin and mineral complex were additionally used. Thioctic acid was prescribed according to the following scheme: stage I — intravenous injections of thioctic acid (600 mg/daily, 5 procedures, every other day); stage II — oral administration of the drug in the dose of 600 mg/daily for 3 months. A significant reduction of pain syndrome and the palpable tension of muscles were noted; the symmetric even muscle tone was revealed. This case-report demonstrates the high efficacy of thioctic acid in treatment of patients with craniomandibular disorders using the 2-stage scheme. There was a significant improvement of quality of life of the patients due to the additional use of vitamin and mineral complex and medical tools (relaxation tire) for treatment at all stages of pain formation.
