© 2018 Voprosy Sovremennoi Pediatrii - Current Pediatrics. All rights reserved. Background. Infections are the main cause of death for patients with autoimmune rheumatic diseases. 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.

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.

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.

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.

To examine the frequency and risk factors for the development of diastolic dysfunction (DD) of the left ventricle (LV) of the heart in patients with chronic kidney disease (CKD). Materials and methods. The study included 225 patients with stage I-CKD of non-diabetic etiology (median age 47.0 years, 50.2% of women). Depending on the degree of decrease in the glomerular filtration rate (GFR), all patients were divided into 3 groups. Group 1 (n=70) consisted of patients with GFR 89-45 ml / min / 1.73 m2, group 2 (n=120) - patients with GFR 44-15 ml / min / 1.73 m2, group 3 (n=35) - patients with GFR <15 mL / min / 1.73 m2. The control group includes persons without CKD. All patients underwent general clinical examination and transthoracic echocardiography; in 86 patients the level of cystatin C in the blood serum was determined. Results. Hypertrophy of the left ventricle (LVH) of the heart was detected in 87 (38.7%) of 225 patients with CKD. Hypertrophic type (type I) of myocardial DD is diagnosed in 90 (41.4%) of 225 patients with CKD. The incidence of myocardial left ventricular dysfunction of the 1st type increased with a decrease in GFR, amounting to 30, 40 and 60% in groups 1, 2 and 3, respectively. The systolic function of the left ventricular myocardium was preserved. Patients with DD were older, they had a higher body mass index (BMI), a more pronounced decrease in GFR, a higher level of fibrinogen. They were more likely to have LVH. The level of cystatin C as the kidney function worsened, but when comparing the mean levels of cystatin C in patients with the presence / absence of DD in the groups isolated depending on the stage of CKD, no statistically significant differences were found. According to the multivariate analysis, the independent predictor of DD was the age (odds ratio 1.106, 95% confidence interval 1.051-1.157, p=0.00001). The conclusion. DD of the myocardium of the LV is detected on average in 40% of patients with CKD, the frequency of its development increases with the progression of renal dysfunction. The development of DD is influenced by traditional factors of cardiovascular risk (age, BMI), as well as the decline in GFR and closely related structural remodeling of LV myocardium.

In most cases, this problem is associated with musculoskeletal system pathology: Rickets in children, and osteomalacia or osteoporosis in adults. However, in recent years, convincing data was obtained on the links between Vitamin D deficiency and cardiovascular pathology. Low Vitamin D levels in humans are associated with the unfavorable cardiovascular risk factors, such as arterial hypertension (AH), diabetes mellitus, and dyslipidemia, which are the predictors of the severe cardiovascular diseases, including strokes and infarctions. It has been demonstrated that Vitamin D has a strong vasoptotective effect via endothelial dysfunction improvement, prevents blood vessels and myocardium remodeling, improves blood pressure parameters, reduces the risk of development of left ventricular hypertrophy, slows down fibrosis, reduces the risk of atherosclerosis, reduces insulin resistance, and also affects inflammation and immunity. This article provides data of Russian and foreign studies demonstrating the effect of Vitamin D deficiency on the development of atherosclerosis, AH, heart rhythm disorder and progression of chronic heart failure.

AIM: To develop new criteria of radical surgery for hilar cholangiocarcinoma (HCC). MATERIAL AND METHODS: There were 165 HCC patients who underwent surgery in 1986-2016 at the Vishnevsky Institute of Surgery. TNM stage distribution: stage I - 4 (2.4%), II - 45 (27.3%) (29 of them are referred to the 1st period of work), IIIA - 23 (13.9%), IIIB - 41 (24.8%), IVA - 35 (21.2%), IVB - 17 (10.3%). 80 (48%) patients underwent hemihepatectomy, 17 (10%) - advanced hemihepatectomy, 16 (10%) - minor liver resection with common bile duct repair, 52 (32%) - common bile duct repair resection. Kaplan-Meier survival analysis was performed. Cox proportional hazard model was applied to access relationship between survival and prognostic factors. Log-rank test was used to compare both survival curves. RESULTS: R0-resection as followed by 5-year survival rate near 32%. Microvascular invasion was observed in 42.9%, lymphovascular invasion - in 88.2%, positive resection margin - in 59.2%, perineural invasion - in 83.3%, cells in surrounding fatty tissue were revealed in 92.3%. Resection may be considered radical (R0) if all variables are absent, 5-7 negative factors are followed by conditionally radical procedure (R+number of positive factors). Long-term outcomes and significance of new criteria were accessed (p=0.004). CONCLUSION: New criteria of radical procedure are presented. The last reflects the concept of dependence of 'pure' surgical edge from not only presence or absence of tumor cells in cut-off plane but also from important morphological features of tumor.

Spinal cord injury (SCI) is a devastating condition that affects mostly young and active individuals but also impacts their family members and results in significant challenges for medical care and social integration. In addition to obvious motor impairment (tetraplegia/paraplegia), these individuals also suffer from a variety of less obvious but devastating autonomic nervous system dysfunctions that negatively impact their health and affect various aspects of daily living. Physical training and sports are essential components of rehabilitation and leaser activities for people with disabilities. Number of individuals with SCI who run an active lifestyle is increasing. Physical activity puts an additional stress on various organs and body systems. The presented manuscript describes in detail cardiovascular dysfunctions in physically active individuals with a SCI, including those engaged in Paralympic sports: low resting blood pressure, orthostatic hypotension, arrhythmias, and the phenomenon of «autonomic dysreflexia». We also address issues related to self-induced episodes of autonomic dysreflexia in order to improve athletic performance ― a phenomenon known as «boosting». Boosting may improve sports performance in short term but is associated with the risk of serious cardiovascular disorders and even sudden death. This practice is considered as anti-doping rule violation by the International Paralympic Committee and thus prohibited. Understanding of the changes occurring in the body of a physically active individual after SCI is necessary for general practitioners, neurologists, rehabilitation specialists, sports medicine physicians, as well as for specialists of adapted physical education and sports.

The main reason of surgical treatment failure in cases of chronic dacryocystitis concurrent with nasolacrimal duct obliteration is scarring of the newly created ostium. This outcome is caused by the continued activity of myofibroblasts that leads to the formation of a rough scar. Mitomycin C is currently considered to be the most preferred anti-fibrotic drug. Nonetheless, contradictory evidence of the drug efficiency stimulates further research for finding alternative anti-fibro-tic therapeutics. Recently, several advances were made in developing new anti-fibrotic drugs, including monoclonal antibodies, small RNA molecules, and other gene therapy formulations, nanoparticles and small-molecule therapeutics. This review article aims to provide up-to-date information on the efficacy of mentioned agents and on prospects of their use in dacryology.

AIMS: On the basis of echocardiography to evaluate the thickness of epicardial fat (TEF) in patients with metabolic syndrome (MS) and to establish a connection with the main indicators of laboratory and instrumental methods of research. MATERIALS AND METHODS: The study included 76 patients, 43 patients with MS and 33 without MS.The average age of patients in the MS group at the time of inclusion in the study was 62.7±10.3 years in the control group (without MS) - 60±14.7 years. All patients underwent a comprehensive examination that included the collection of complaints, study of history, physical examination, anthropometric measurements, laboratory (including the study of the levels of caspase - 8, leptin in blood plasma enzyme-linked immunosorbent assay using kits «Platinum ELISA») and instrumental examination (echocardiography, ultrasound examination of organs of small pelvis). TEF was determined using transthoracic echocardiography on the machine Acuson Sequoia 512. RESULTS: According transthoracic echocardiography was significantly higher in the group of patients with MS and was 4.67±1.7 mm, as compared to 2.66+1.15 mm in the control group (p<0.001). Identified moderate and strong correlation between TEF and weight of the patients, waist circumference, ratio of waist circumference to hip circumference, body mass index, glucose levels in the blood plasma, the presence of diabetes mellitus type 2, ultrasonic signs of steatosis of the liver and pancreas, increased aminotransferases, the level of caspase-8 concentration in plasma leptin. Patients the MS group with increased TEF increases the risk of developing hypertension, ischemic heart disease, left ventricular hypertrophy, diastolic dysfunction of the left ventricle type 2, level of caspase-8 and concentration in plasma leptin. CONCLUSION: Based on the obtained data, the measurement of TEF is justified in patients with MS in everyday clinical practice. The correlations between theTEF and the clinical and metabolic parameters of the CVD and MS make it possible to consider the TEF as a new marker of the risk of developing MS and cardiovascular diseases.

Methods: 44 (M/F - 18/26) DMARD-na?ve patients (pts) with active EPsA, according to the CASPAR criteria, mean age 37.5±11.3 years, PsA duration 7 [4; 24] months, psoriasis duration 36 [12; 84] months, disease activity index (DAS) 3.78 [3.18; 4.67], DAS28 4.33 [3.67; 4.8] study were included. At the baseline and every other 3 months for total 12 months of therapy all pts underwent standard clinical examination, tender joint count (TJC), swollen joint count (SJC), patient pain VAS, patient/physiciańs global disease activity VAS, enthesitis by Leeds Enthesial Index (LEI)+Plantar Fascia (PF), dactylitis, Psoriasis Area Severity Index (PASI), body surface area (BSA), Health Assessment Questionnaire (HAQ), DAS, DAS28-C-RP, C-RP (mg/l). The dose of MTX s/c was escalated by 5 mg every 2 weeks from 10 mg/wk to appropriate dose 20-25 mg/wk according to the drug intolerance. If pts does not achieve the lower disease activity (LDA), MDA or remission after 3 months of MTX subcutaneous (s/c) mono-therapy, then combination therapy of MTX+Adalimumab (ADA) by standard regime was continued up to one year. At 12 months of therapy the proportion of pts who attained LDA by DAS/DAS28 or remission by DAS<1.6/DAS28-C-RP<2.6 or MDA, ACR20/50/70, PASI75 and dynamics of HAQ, LEI+PF, dactylitis were calculated. Mean±SD, Me [Q25; Q75], %, Friedman (Fr.) ANOVA, U-test, Wilcoxon test were performed. All p<0.05 were considered to indicate statistical significance. Results: At one year of treatment according to T2T strategy significant improvements disease activity and physical health function related to quality of life was seen. By 12 months of therapy remission by DAS and MDA was reached 61.4%/65.9% of pts accordingly. By 12 months of therapy ACR20/50/70 was seen in 88%/77%/59% of pts. In pts with BSA≥3% (n=16) at baseline psoriasis improvements by PASI75 was seen in 88% of pts. In 55% of active EPsA pts MTX (s/c) mono-therapy was an effective treatment. Conclusions: One-year treatment according to T2T strategy significantly improves all PsA clinical domains - Arthritis, dactylitis, enthesitis, skin psoriasis and quality of life despite of type of treatment. It seems that T2T is a useful strategy in EPsA but additional research concerning its implementation in real practice are needed.

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.

© 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..
