Mortality and risk factors for non-communicable diseases in Russia: Specific features, trends, and prognosis
Boytsov S.A., Deev A.D., Shalnova S.A.
Abstract
In the Russian Federation, the increase in all-cause and cardiovascular disease mortality began in the 1960s and lasted almost continuously until 2003. In our country, the characteristics of mortality are its substantially higher rates among men and a large regional variability, which is associated with economic, climatic, and geographic factors. Urbanization coupled with dietary changes and the higher prevalence of hypertension is the most likely initial impetus to the rise in mortality rates. The subsequent increase in mortality can be explained by the higher prevalence of behavioral and biological risk factors, alcoholism, and, since the 1990s, by heavy and protracted socioeconomic upheavals and lifestyle changes. The mortality decline since 2006 has been linked to the strengthening of the health system and to the reduction in the prevalence of smoking among men and hypertension in women. The slowing down of the pace of mortality decline may be due to the increase in the prevalence of hypertension and obesity among men. The modelling data show that by 2025, reductions in smoking prevalence rates by 23% among men and by 12% among women and increases in the efficiency of hypertension treatment by 17.2% in men and by 11.2% in women will reduce cardiovascular mortality rates by 15%.

Isakova Z.T., Talaibekova E.T., Asambaeva D.A., Kerimkulova A.S., Lunegova O.S., Aldashev A.A.
Abstract
Aim. To study the association of the polymorphic marker Glu23Lys in the KCNJ11 with the development of hypertension in Kyrgyz patients. Subjects and methods. This case-control study enrolled 214 unrelated ethnic Kyrgyzes, in which a study group included 152 hypertensive patients (82 men and 70 women) and a control group consisted of 109 apparently healthy individuals (61 men and 48 women). The examinees’ mean age was 55.2±10.1 years. Hypertension was verified when blood pressure (BP) was above 140/90 mm Hg. Polymerase chain reaction-restriction fragment length polymorphism analysis was used to identify the polymorphic marker Glu23Lys in the KCNJ11 gene. Results. In the hypertension and control groups, the prevalence of 3 genotypes (Glu23Glu, Glu23Lys, and Lys23Lys) of the Glu23Lys polymorphism in the KCNJ11 gene differed significantly (χ2=8.04; p=0.018). The Lys23Lys and Glu23Lys genotypes were statistically more frequently recorded in the hypertension group and the homozygous Glu23Glu genotype was, on the contrary, more common in the control group than in the study one. In the hypertension group, the 23Lys allele frequency was statistically significantly higher than that in the control one (χ2=7.36; p=0.0067). The carriage of the 23Lys allele increased the risk of hypertension by 1.68 times (odds ratio (OR), 1.68; 95% confidence interval (CI), 1.17—2.41), that of the Glu23 allele had, on the contrary, a protective effect (OR, 0.60; 95% CI, 0.41—0.86). Conclusion. The polymorphic marker Glu23Lys in the KCNJ11 gene is associated with hypertension in the Kyrgyzes. The 23Lys allele is a marker for the higher risk of hypertension.

Azizova T.V., Grigoryeva E.S., Hunter N., Pikulina M.V., Moseeva M.B.
Abstract
Aim. To assess mortality from circulatory diseases (CD) in a cohort of workers exposed occupationally to chronic radiation in relation to external and internal exposure, by taking into account known non-radiation risk factors (RFs), such as smoking (including smoking index), alcohol consumption, hypertension, and body mass index. Subjects and methods. Mortality from CD (ICD-10: I00 — I99) was studied in a cohort of 22,377 nuclear power plant («Mayak» Production Association) workers exposed occupationally to chronic radiation. The study was based on the individual dose estimates of external and internal exposure taken from the new Mayak workers dosimetry system 2008 (MWDS-2008). The quantitative characteristics of smoking (smoking index) were used for the first time to assess the risk for CD in the cohort of workers exposed to chronic radiation. Results. There was a statistically significant linear relationship between CD mortality and external gamma-dose after adjusting for the non-radiation RFs; the excess relative risk per unit dose (ERR/Gy) was 0.05 (95% confidence interval (CI): 0 to 0.11). Introducing an additional adjustment for internal alpha-dose resulted in a twofold increase in ERR/Gy (0.10 (95% CI: 0.02 to 0.21). There was a statistically significant increasing trend in CD mortality with the elevated absorbed dose from internal alpha-radiation in the liver (ERR/Gy=0.27; 95% CI: 0.12 to 0.48). However, ERR/Gy decreased and lost its statistical significance after adjusting for external gamma-dose. Conclusion. The results of this study are in good agreement with risk estimates obtained in the Japanese cohort of atomic bomb survivors and in the cohorts of occupationally exposed workers.

Associations between high levels of hostility and coronary heart disease in an open urban population among 25—64-year-old men
Akimova E.V., Akimov M.Y., Gakova E.I., Kayumova M.M., Gafarov V.V., Kuznetsov V.A.
Abstract
Aim. To establish the associations of the prevalence of coronary heart disease (CHD) with high levels of hostility in the open population of 25—64-year-old men in an average urbanized Siberian town. Subjects and methods. A cross-sectional epidemiological survey was conducted in a representative sample of the electorate of a Tyumen administrative district among 1000 males, with 250 being in each of 4 life decades (25—34, 35—44, 45—54, and 55—64 years). There were 850 (85%) responses. Different forms of CHD were identified by standard methods (the WHO exertional angina questionnaire, resting EEG, and Minnesota coding) used in epidemiological surveys. Definite CHD (DCHD) and possible CHD were identified. A continuous survey method was used by self-filling out the WHO MONICA-psychosocial questionnaire to estimate the levels of hostility. Results. In an average urbanized Siberian town, the prevalence of high levels of hostility among 25—64-year-old men was 46.4% (age-adjusted rate). The high levels of hostility increased with age, peaking in the 55—64-year-old group. In the Tyumen male population aged 25—64-year-old, the odds ratio (OR) for coronary heart disease and high levels of hostility was 2.71; 95% confidence interval (CI), 1.63—4.52 (p<0.05); that for DCHD was almost twice higher (OR, 4.65; 95% CI, 2.14—10.12 (p<0.05). In the older men aged 55-64 years, OR for coronary heart disease and high levels of hostility was 5.42; 95% CI, 2.32—12.66 (p<0.05); that for DCHD was 25.85; 95% CI, 3.30—202.60 (p<0.05). Conclusion. Consequently, the epidemiological criteria for psychosocial risk factors, including hostility, which are detected by the standardized survey methods, should be used in prophylactic examinations of a male population and in the selection of able-bodied people with cardiovascular disease to be comprehensively examined and followed up.

Arutyunov G.P., Dragunov D.O., Arutyunov G.P., Sokolova A.V., Papyshev I.P., Kildyushov E.M., Negrebetsky V.V., Fedorova V.N.
Abstract
Aim. To determine a relationship between the level of total sodium in the myocardium to its stiffness. Subjects and methods. The investigation enrolled 18 hypertensive patients who had suddenly died; their mean age was 40±10 years; mean waist circumference, 102±12.5 cm; height, 170±7.7 cm; myocardial mass, 319±53 g. Results. The variation in the myocardial level of total sodium averaged 211.7±37.5 (min, 71.5; max, 226.17) mmol/l. The sodium level was ascertained to be affected to the greatest extent by myocardial mass (SS=3615.56; p=0.00029) and age at death (SS=1965.568; p=0.0029), whereas gender and smoking had a considerably lower impact (SS=778.584; p=0.03). A univariate regression analysis showed that there was a relationship between myocardial sodium levels and the thickness of the anterior wall of the left ventricle (β=0.94; p=0.000001; r2=0.88), that of the anterior wall of the right ventricle (β=0.82; p=0.000021; r2=0.66), and that of the interventricular septum (β=0.94; p=0.000001; r2=0.89). The wall thickness of the myocardium was established to depend on its sodium level (SS=21813.89; p=0.000001; r2=0.88): the higher sodium amount in the myocardium, the thicker its walls. The average velocity of acoustic wave propagation was 6.24±0.51 m/sec. A significant correlation was observed between sodium concentrations in the myocardium and its stiffness (β=0.72; p=0.00062; r2=0.49). Conclusion. The level of sodium deposited in the myocardium, which is directly related to dietary sodium intake, is significantly correlated with myocardial stiffness. It can be assumed that the elevated level of sodium deposited in the myocardium is an independent factor that changes the stiffness of the myocardium and appears to influence the development of its diastolic dysfunction.

Light-chain deposition disease is a hematologic problem
Rekhtina I.G., Mendeleeva L.P., Biryukova L.S.
Abstract
Aim. To analyze clinical and laboratory data and treatment results in patients with light-chain deposition disease (LCDD). Subjects and methods. Nine patients with LCDD and kidney injury were examined. The diagnosis was based on the results of light and immunofluorescence microscopy of renal biopsy specimens. All the patients received bortezomib, cyclophosphamide, and dexamethasone (VCD) induction therapy. Results. Six patients were diagnosed with multiple myeloma; in 3 patients LCDD was considered within monoclonal gammopathy manly involving the kidney. By the initiation of therapy, all the patients were diagnosed as having chronic kidney disease (Stage III (n=2), Stage IV (n=2), and dialysis-related renal failure (n=5)). After the VCD treatment, 7 of 9 patients achieved a hematologic response. Second-line therapy with lenalidomide proved to be effective in the other 2 cases. Five patients achieved complete remission; 3 had a very good partial remission. Thereafter, 2 patients received high-dose melphalan chemotherapy and autologous hematopoietic stem cell transplantation. Better renal function was noted in only 2 cases. Conclusion. Despite the high efficiency of therapy aimed to reduce monoclonal light chains; improved renal function was observed in only 2 (22%) patients. Such low rates of a renal response were due to the late initiation of therapy.

Dorokhina E.I., Magomedova A.U., Galtseva I.V., Dvirnyk V.N., Glinkina S.A., Kulikov S.M., Kravchenko S.K.
Abstract
Aim. To estimate the number of early progenitors of bone marrow (BM) hematopoiesis in patients with diffuse large B-cell lymphoma (DLBCL) in the late period after high-dose chemotherapy (HDCT) according to the mNHL-BFM-90 program. Subjects and methods. The investigators analyzed the results of BM immunophenotypic and histological studies in 40 patients (median age, 57 years) with DLBCL who received HDCT according to the mNHL-BFM-90 program at the Hematology Research Center (HRC), Ministry of Health of the Russian Federation (MHRF), in the period 2002 to 2009. A comparison group consisted of 19 patients (median age, 70 years) treated according to the CHOP/R-CHOP program at HRC, MHRF, in the same period. The median follow-up period was 6 years. The results of BM examination were analyzed before and 5—10 years after the end of HDCT. Immunophenotypic study determined the number of early CD34+ hematopoietic progenitors. BM cellularity, the size of erythroid, granulocytic and megakaryocytic lineages, their ratio, the presence of dysplasia signs, and secondary stromal changes were histologically determined. The BM toxic injury signs found for the first time were evaluated as manifestations of late myelotoxicity. Results. At 5-to-10-year follow-ups after the end of HDCT according to the mNHL-BFM-90 program, the patients showed a smaller number of early CD34+ progenitors of BM hematopoiesis in 31 (78%) cases than those treated according to the CHOP/R-CHOP-21 program (n=8 (2%)) (p=0.005). Myelopoiesis with decreased CD34+ cell count was characterized by hypocellularity in 8 (26%) patients (p=0.07), the narrowing of megakaryocytic lineage in 14 (45%) (p=0.006), erythroid one in 7 (23%) (p=0.01), and granulocytic one in 8 (26%) (p=0.92), pronounced secondary stromal changes in 15 (48%) (p=0.03), and grade 1 thrombocytopenia in 13 (42%); p=0.02). Conclusion. There is evidence that the number of early CD34+ progenitors of BM hematopoiesis decreased in patients with DLBCL in the late period after HDCT. The investigation shows the relationship of the reduction in the number of early CD34+ progenitors of BM hematopoiesis in the late follow-up period to the presence of pronounced secondary changes in the BM stroma (p=0.02). There was no statistically significant relationship of the decreased number of CD34+ cells to the age younger or older than 60 years, to the period after the end of chemotherapy, to gender or presence of specific BM injury.

Komarova E.B., Rebrova O.A., Pokrushka I.I., Kindritskaya Y.G.
Abstract
Aim. To study the specific features of joint ultrasound readings in rheumatoid arthritis (RA) in relation to its duration. Subjects and methods. A total of 162 patients (mean age, 43.54±11.1 years) with a mean RA duration of 3.22±3.13 years were examined. Gray-scale ultrasound study (USS) of hand and ankle joints was performed using color Doppler energy imaging. Group 1 included 78 patients with a RA duration of less than 2 years; Group 2 consisted of 84 patients with a RA duration of more than 2 years. Results. Joint USS diagnosed osteochondral erosions twice more frequently than conventional radiography. 82% of the patients with RA were found to have synovitis; 77% had thickening of the synovial membrane (SM) with hypervascularization, the vascularization intensity scores of 2—3 being predominant; and 54% had tenosynovitis of the carpal extensor tendon. Effusion into the joint cavity, SM hypervascularization scores of 2—3, and tenosynovitis were most common in Group 1. SM thickening and osteochondral erosions were prevalent in Group 2. Conclusion. Joint USS revealed that angiogenesis and inflammation were dominant in the patients with a RA duration of less than 2 years and the proliferative-destructive processes were prevalent in those with a RA duration of more than 2 years. Identifying the predominance of pathophysiological processes in each specific patient with RA will be able to individualize therapy and to improve the prognosis of the disease.

Diagnosis and treatment of benign paroxysmal positional vertigo in common clinical practice
Lebedeva N.V., Zamergrad M.V., Parfenov V.A., Antonenko L.M.
Abstract
Aim. To analyze typical medical practice in managing patients with benign paroxysmal positional vertigo (BPPV). Subjects and methods. 33 patients (5 men and 28 women; mean age, 58 years) with BPPV who had been referred for consultation to the Medical Diagnostic Department, Clinic of Nervous Diseases, I.M. Sechenov First Moscow State Medical University, regarding for vertigo, were examined. Information about the disease before visiting the clinic, such as the duration of vertigo, its pattern, and triggers, previously established diagnoses, prescribed treatment and its efficacy, concomitant diseases, was analyzed. Results. BPPV was not timely diagnosed in 93.9% of cases. The cause of vertigo was most commonly mistakenly assumed to be cerebrovascular disease (66.6%) and cervical spine pathology (15.1%). During a primary examination, none of the patients underwent positional tests (otoneurological examination) that formed the basis for the diagnosis of BPPV. Alternatively, 90.3% of cases underwent instrumental examination: magnetic resonance imaging of the brain, X-ray of the cervical spine, and ultrasonic duplex scanning of the brachiocephalic arteries. Ineffective diagnosis led to the choice of nonoptimal treatment tactics: instead of therapeutic repositioning maneuvers (RM), the patients received therapy with drugs, such as various vasoactive agents (84.8%), nootropic and chondroprotective drugs (12%), or muscle relaxants (9.1%). After BPPV was detected, all patients underwent curative RM, which resulted in regression of the disease. One-year follow-up of the patients showed that the therapeutic effect of RM persisted. Conclusion. Lack of effective and timely diagnosis of BPPV reflects physicians’ poor awareness that this condition is the most common cause of vestibular vertigo. The role of vascular and cervicogenic factors in the development of vertigo is overestimated. Most patients with BPPV undergo unreasonable examinations and receive ineffective treatment. It is necessary to raise awareness of BPPV among of physicians and to set up specialized centers for the management of patients with dizziness.

Bulgakova V.A., Poromov A.A., Grekova A.I., Pshenichnaya N.Y., Selkova E.P., Lvov N.I., Leneva I.A., Shestakova I.V., Maleev V.V.
Abstract
Aim. To identify risk factors (RFs) for the development of bacterial complications and the prolonged course of influenza and other acute respiratory viral infections (ARVIs) among inpatients treated in Russian healthcare facilities in the post-pandemic period; to determine the clinical presentation of the disease (flu-like syndrome) in risk-group people and to evaluate the efficacy of antiviral therapy with arbidol (umifenovir). Materials and methods. The investigators retrospectively analyzed randomly selected medical records of inpatients with influenza and other ARVI in 88 hospitals from 50 regions of the Russian Federation: those of 3532 and 1755 patients in the 2010-2011 and 2014-2015 seasons, respectively, by applying parametric and nonparametric statistical methods. Results. The built database of patients with influenza-like syndrome contained data from the histories of 2072 men and 2537 women, of whom there were 317 (12.49%) pregnant women; gender evidence was not given in the medical records for 678 patients. 382 (7.2%) were vaccinated against influenza. 1528 (28.9%) people were admitted to hospital with various complications. Information on laboratory tests was available in 1691 (31.98%) patients; of these, 1291 (76.4%) were detected to have influenza and other respiratory viruses. Influenza viruses were found in 1026 (60.7%) examinees; influenza A viruses in 712 (42.1%) people while pandemic strain of swine influenza A/H1N1 and A/H3N2 viruses was detected in 487 (28.8%) and 107 (6.3%) patients, respectively; influenza A subtype was indicated in 118 (7%) persons with laboratory-confirmed influenza virus. Influenza B viruses were found in 314 (18.6%) examinees. Other types of respiratory viruses were detected in 265 (15.7%) patients. The body mass index exceeded 30 kg/m2 in 227 (4.3%) patients. Single-factor analysis of variance revealed factors influencing the course of flu-like syndrome and identified risk groups: children younger than 2 years old and adults over 65, pregnant women, and people with chronic somatic diseases and obesity. The high-risk groups exhibited a more severe course of flu-like syndrome than did the patients outside the risk groups. The incidence of complications was higher, especially in the under 2-year-year-old children and in patients with endocrine, metabolic, or respiratory diseases, with a large proportion of complications being pneumonia. The efficacy of antiviral therapy was higher in the elderly, patients with chronic diseases, and pregnant women than in patients not at risk. In patients treated with umifenovir (provided that it was administered in the first 48 hours after disease onset), the duration of fever and frequency of complications proved to be lower than those in patients who did not receive antiviral therapy. Conclusion. The FRs for influenza and ARVI complications are patient’s age (children under 3 years of age and adults older than 65 years), the presence of chronic somatic diseases, and pregnancy. Patients with endocrine, eating, metabolic (including obesity), circulatory, and respiratory disorders are at high risk for influenza and ARVI complications. Umifenovir therapy substantially reduces the duration of fever and risk of complications, especially in patients with laboratory-confirmed influenza infection

Ryzhko V.V., Grachev A.E., Klodzinsky A.A., Ivanova T.V., Sataeva M.S., Gribanova E.O.
Abstract
Concurrences of multiple myeloma with myeloproliferative diseases or secondary myeloid leukemoid reactions are rather rare. The paper describes 3 cases of multiple myeloma: the first case concurrent with neutrophilic leukocytosis; the second case with secondary erythropoetin-dependent erythrocytosis, and the third case with chronic myeloid leukemia. In such cases, an accurate diagnosis requires molecular testing, besides routine clinical and laboratory studies. The paper discusses therapeutic strategy in cases of a concurrence of 2 competing tumors of the blood system: to treat them simultaneously or the most aggressive tumor now, as well as a relationship between multiple myeloma and chronic myeloid leukemia, other myeloproliferative disorders, and secondary myeloid leukemoid reactions.

Ntanishyan K.I., Sabirov K.R., Shcherbakova O.V., Vybornykh D.E., Shupletsova I.A., Tsvetaeva N.V.
Abstract
The paper describes a case of autoimmune hemolytic anemia (AIHA) in a 27-year-old woman whose examination revealed mesenteric teratoma. AIHA was characterized by a hypertensive crisis and a temporary response to corticosteroid therapy that was complicated by the development of somatogenic psychosis and discontinued. A relapse of hemolysis developed 6 months later. The patient underwent laparoscopic splenectomy and removal of mesenteric root teratoma. Immediately after surgery, a hematological response was obtained as relief of hemolysis and restoration of a normal hemoglobin level. There is a sustained remission of AIHA for the next 16 months.

Myocardial fibrosis: Current aspects of the problem
Karetnikova V.N., Kashtalap V.V., Kosareva S.N., Barbarash O.L.
Abstract
Fibrosis is one of the main components in the progression of most cardiovascular diseases, including coronary heart disease, by causing structural changes in the myocardium and vascular wall. The quantitative and qualitative characteristics of fibrosis of the myocardium are responsible for decreasing its elastic properties, developing diastolic dysfunction, impairing myocardial contractility, developing systolic dysfunction and cardiac arrhythmias, and worsening coronary blood flow in patients with heart failure of different etiologies. The important aspect of studying fibrosis is not only its interpretation as a model of the typical pathological process, but also its consideration as a systemic lesion of various organs and tissues. At the same time, the identification of myocardial fibrosis biomarkers that are available for their determination in circulating blood is of particular interest. Since there was evidence for the role of fibrosis in developing dysfunction of various organs and ensuring the systematicity of most diseases, especially at their development stages, the process of fibrosis came to be regarded as a promising therapeutic target. It is relevant to further investigate myocardial fibrosis, which is aimed at increasing the efficiency of its diagnosis and predicting its course and pathogenetically sound therapy.

Algorithm for the management of patients with stable coronary artery disease and high-grade ventricular arrhythmias
Ryngach Е.А., Treshkur T.V., Tatarinova A.A., Shlyakhto E.V.
Abstract
The paper gives an original algorithm for the management of patients with stable coronary artery disease, preserved/moderately reduced left ventricular systolic function, and high-grade ventricular arrhythmias from the first registration of the latter to the choice of treatment policy. Great attention is paid to the assessment of a private clinical case, by determining the nature of arrhythmias, and to the involvement of autonomic regulation in the genesis of ventricular arrhythmias. The importance of topical diagnosis of ventricular arrhythmias and identification of psychological disorders is emphasized. Diagnostic problems are solved in a step-by-step fashion using up-to-date techniques. The key point of the algorithm proposed is to prevent sudden cardiac death.

Obstructive sleep apnea at high altitude
Myrzaakhmatova A.K.
Abstract
Obstructive sleep apnea (OSA) is an important and socially relevant problem of modern medicine, which is referred to as a most common pathological condition. The problem of OSA is especially urgent for inhabitants of high mountainous regions, as a combination of climatic, social, and cultural factors can significantly affect the course of the disease in both indigenous highlanders and people temporarily residing at high altitude. The paper reviews the current literature covering the problem of OSA at high altitude. It gives the data of Russian and foreign literature on the pathogenesis and clinical presentation of OSA. The author also analyzes an update on the impact of high altitude on the course of OSA in indigenous highlanders and people temporarily living at high altitude. She emphasizes the role of hypobaric hypocapnia as the most important factor for the development of central sleep apnea in the presence of conditions that are obstructive and aggravating the course of the disease.

The problem of obstructive sleep apnea syndrome in asthmatic patients
Sheludko E.G., Naumov D.E., Perelman Y.M., Kolosov V.P.
Abstract
Asthma and obstructive sleep apnea syndrome (OSAS) are one of the most common chronic respiratory diseases. These have common risk factors that include obesity, gastroesophageal reflux disease (GERD) and impaired nasal breathing (allergic rhinitis, sinusitis). At the same time, experimental evidence demonstrates common pathophysiological mechanisms of these diseases, such as involvement in the process of the respiratory tract, a systemic inflammatory response, and implementation of neuromechanical reflexes. Thus, there is an obvious synergism between these conditions, which affects symptoms, response to therapy, and prognosis. The available data allow discussion on whether there is a need to identify and treat OSAS in asthmatic patients. By keeping in mind the high incidence of OSAS in patients with severe asthma, it may be suggested that treatment for OSAS can reduce the number of exacerbations, improve the quality of life, and decline the number of obstinate asthma cases. It is very important for general practitioners to assess risk factors, such as body weight, nasal stuffiness, and GERD, and to utilize screening tools for more efficient use of healthcare resources. Considering the known positive effects of CPAP therapy in short-term studies, future investigations should focus on the impact of CPAP therapy on asthma symptoms in the long-term, as well as on the effects of asthma drugs on the course of OSAS.

Chronic obstructive pulmonary disease concurrent with metabolic syndrome: Pathophysiological and clinical features
Budnevsky A.V., Ovsyannikov E.S., Labzhania N.B.
Abstract
Chronic obstructive pulmonary disease (COPD) still remains a serious public health problem, which is a common cause of disability and death in the able-bodied population. Furthermore, the number of patients with metabolic syndrome (MS) is steadily increasing worldwide. Recently, there is also an increase in the number of patients with COPD concurrent with MS, which is a mutually confounding risk factor for concomitant cardiovascular disease and adversely affects prognosis in these patients. Systemic subclinical inflammation is a common link between COPD and the components of MS. Systemic inflammation in patients with comorbidity is complemented by an inflammatory process in the abdominal visceral adipose tissue that serves as a source of proinflammatory adipokines (leptin, resistin, and tumor necrosis factor-α). Patients with COPD in the presence of MS components have in general higher ventilation needs, more obvious clinical manifestations of bronchopulmonary diseases, and more frequent COPD exacerbations and frequently require higher doses of inhaled glucocorticosteroids. As compared with normal-weight patients with COPD, obese patients with this condition have more limited physical activity and much more exercise intolerance. There are currently no practical recommendations for the management of patients with comorbidity; patients with COPD concurrent with MS need an individual therapeutic approach. It is important to elaborate a package of preventive measures to improve quality of life in patients, to reduce the incidence of systemic complications, and to achieve symptomatic improvements. Thus, to develop and implement practical guidelines for physicians and patients are an urgent issue.
