[Rehabilitation program of post-COVID-19 syndrome with the use of nitric oxide and molecular hydrogen].

Рost-COVID-19 syndrome (PS) is one of the medical and social problem. According to WHO, 10-20% of COVID-19 patients suffer from PS. The use of medical gases - inhaled nitric oxide (iNO) and molecular hydrogen (iH2) - may influence on the mechanisms of development PC. AIM: To evaluate the safety and efficacy of the combined inhalation of NO and H2 (iNO/iH2) in patients with respiratory manifestations of PS. MATERIALS AND METHODS: 34 patients with PS (11 men/23 women, 60.0±11.7 years) were included in the prospective open-label controlled study in parallel groups: the main group (n=17) received iNO/iH2 for 90 minutes once a day for 10 days (concentration of NO 60 ppm, H2<4% in the gas mixture), the control group (n=17) didn't receive inhalations. The period from the confirmation of COVID-19 to the start of the study was 641.8±230.5 days. The groups did not differ in the baseline parameters. The clinical symptoms (from the self-observation diary and mMRC questionnaires, "dyspnea language"), FAS, HADS, SF-36 scores, 6-minute walk test, the blood serum parameters of oxidative stress, the dynamics of the microcirculation in the eye bulbar conjunctiva were evaluated. The individual dose of iNO has chosen during a 15-minute test (the positive dynamics of the microcirculation have indicated that the dose was selected correctly). RESULTS: The decrease the symptoms severity, such as dyspnea, cough, fatigue and palpitations (p<0.005), the increase in SF-36 questionnaire scores (p=0.006) and a reducing of FAS score (p=0.001), as well as the anxiety component of HADS (p=0.02) were revealed at the end of treatment in the main group compared to the control group. We observed an improvement in distance walked (p=0.01) and the values SpO2 (p=0.04) in 6-minute walk test, the increase in the volumetric blood flow velocity in venules (p<0.001), and the date in oxidative damage (p<0.001) and antioxidant activity (p=0.03) parameters in the blood serum. CONCLUSION: The results of the study demonstrate clinical efficacy iNO/iH2 on clinical indicators, parameters of oxidative stress and microcirculation in patients with PS.

The impact of ATP-sensitive potassium channel modulation on mitochondria in a Parkinson's disease model using SH-SY5Y cells depends on their differentiation state.

Inward rectifying potassium channels sensitive to ATP levels (KATP) have been the subject of investigation for several decades. Modulators of KATP channels are well-established treatments for metabolic as well as cardiovascular diseases. Experimental studies have also shown the potential of KATP modulation in neurodegenerative disorders. However, to date, data regarding the effects of KATP antagonists/agonists in experiments related to neurodegeneration remain inconsistent. The main source of confusion in evaluating available data seems to be the choice of experimental models. The present study aims to provide a comprehensive understanding of the effects of both opening and blocking KATP channels in two forms of SH-SY5Y cells. Our results offer valuable insights into the significance of metabolic differences between differentiated and non-differentiated SH-SY5Y cells, particularly in the context of glibenclamide and diazoxide effects under normal conditions and during the initiation of pathological events simulating Parkinson's disease in vitro. We emphasize the analysis of mitochondrial functions and changes in mitochondrial network morphology. The heightened protein expression of KATP channels identified in non-differentiated SH-SY5Y cells seems to be a platform for a more significant impact of KATP modulators in this cell type. The efficiency of rotenone treatment in inducing morphological changes in the mitochondrial network depends on the differentiation status of SH-SY5Y cells.

[The determinants of vaccination against the new coronavirus infection (COVID-19) of residents of the circumpolar region of Russia].

The maintenance of health of residents of the Northern Regions of Russia, including those living in the Arctic zone of the cbountry, is a condition of its advance development in XXI century. The percentage of Russian citizen vaccinated against the new coronavirus infection (COVID-19) does not exceed 50% after beginning of implementation of vaccination program. It can be conditioned by lower level of both of credence of citizen to health care system and health literacy.Purpose of the study is to establish determinants of vaccination of population against COVID-19 in circumpolar region of Russia as exemplified by the Arkhangelsk Oblast.The sociological survey was carried out using the interview technique of patients of medical organizations (n=433) and conditionally healthy residents of the Arkhangelsk Oblast (n=139). To evaluate the level of general health literacy the Russian version of questionnaire HLS19 - Q22-RU was applied. The most of conditionally healthy respondents and consumers of medical services looked for information about methods of prevention and treatment (80.4% and 58.2% correspondingly), had an experience of vaccination against COVID-19 (79% and 56.3% correspondingly). The relative chances of conditionally healthy respondents, women, and respondents having no children and no credence to national health care system to independently look for information related to COVID-19 is higher at 2.94, 2.08, 1.55 and 1.48-1.57 times correspondingly. The relative chances of conditionally healthy respondents having no children in family and assessing one's economic status as "higher than average" to be vaccinated against COVID-19 is higher at 4.02, 1.52, 1.53 times correspondingly. Availability of experience of vaccination against COVID-19 is conditioned by higher level of general health literacy.In the Arkhangelsk Oblast and other circumpolar regions of Russia the programs of increasing loyalty of citizen to measures of population prevention, including vaccine prevention, is to be implemented with consideration of established determinants of of vaccinations against COVID-19.

Selection of endogenous control and identification of significant microRNA deregulations in cervical cancer.

Introduction: Cervical cancer causes approximately 350,000 deaths each year. The availability of sensitive and specific diagnostic tests to detect cervical cancer in its early stages is essential to improve survival rates. Methods: In this study, we compared two strategies for selecting endogenous controls: miRNA profiling by small-RNA sequencing and a commercially available microfluidic card with 30 recommended endogenous controls preloaded by the manufacturer. We used the RefFinder algorithm and coefficient of variation to select endogenous controls. We selected the combination of miR-181a-5p and miR-423-3p as the most optimal normalizer. In the second part of this study, we determined the differential expression (between tumor/non-tumor groups) of microRNA in cervical cancer FFPE tissue samples. We determined the comprehensive miRNA expression profile using small-RNA sequencing technology and verified the results by real-time PCR. We determined the relative expression of selected miRNAs using the 2-ΔΔCt method. Results: We detected statistically significant upregulation of miR-320a-3p, miR-7704, and downregulation of miR-26a-5p in the tumor group compared to the control group. The combination of these miRNAs may have the potential to be utilized as a diagnostic panel for cervical cancer. Using ROC curve analysis, the proposed panel showed 93.33% specificity and 96.97% sensitivity with AUC = 0.985. Conclusions: We proposed a combination of miR-181a-5p and miR-423-3p as optimal endogenous control and detected potentially significant miRNAs (miR-320a-3p, miR-7704, miR-26a-5p). After further validation of our results, these miRNAs could be used in a diagnostic panel for cervical cancer.

[Hydrogen effect on the mechanisms of mucosal immunity in patients with COVID-19].

AIM: To study the inhalation of an active form of hydrogen effect to mucosal and system immunity in a rehabilitation program for health workers. MATERIALS AND METHODS: The study involved patients that survived COVID-19 after therapy with inhaled hydrogen for 90 minutes (n=30), and a control group of patients treated according to standard protocol for managing patients that survived COVID-19 during the rehabilitation period (n=30). Biomaterial was carried out in 2 stages: on the first day of the study, before the accepted therapy and on the 10th day of the study. The indicators of humoral and cellular immunity were studied. The levels of secretory immunoglobulin A (sIgA) and IgG were investigated using the method of enzyme-linked immunosorbent assay. Phagocytosis was assessed on a Beckman Coulter FC-500 flow cytometer. Statistical data processing was carried out in the GraphPad Prism 7.00 software using nonparametric methods. RESULTS: It was shown that the phagocytic index (PI) of monocytes in nasal scrapings after inhaled hydrogen treatment did not significantly change relative to the first day of treatment and control, while the PI of granulocytes in nasal scrapings significantly increased relative to the first day by 2.5 times (p=0.000189), as well as relative to the control by 1.1 times (p=0.047410). PI of monocytes in pharyngeal scrapings showed a significant increase relative to the first day of treatment by 2.8 times (p=0.041103), however, did not differ relative to the control. PI of granulocytes of pharyngeal scraping did not differ significantly relative to the first day and control. PI of granulocytes and blood monocytes of the studied group did not change significantly. PI of granulocytes and monocytes of peripheral blood relative to control during therapy did not change. The sIgA level in nasal scrapings significantly increased by 2.9 times, while in pharyngeal scrapings the level of sIgA significantly decreased by 2 times. Сonclusion. We have shown an increase in granulocytes PI in the nasal cavity and oral monocytes, as well as in the level of sIgA in the nasal cavity during therapy with active hydrogen. The data obtained indicate the effectiveness of therapy, which can be used both in the treatment of COVID-19, and in post-COVID syndrome as an additional therapy. The absence of changes in blood parameters, as well as individual links in nasal and pharyngeal scrapings, requires further study to develop ways to overcome treatment tolerance.

The medical demographic characteristic of group of citizen injured in road accidents on the Federal Highway.

The role of citizen of elderly age in road accidents on the Federal Highway was principally passive since passengers of vehicles predominated (p<0,0001). The most of victims of elderly age (66,7%) suffered of combined lesions. Considering gender of victim, presence of ethanol in blood at the moment of hospitalization, the role of victim of road accident and degree of severity of lesions in citizen of elderly age was in overall higher than in citizen of able-bodied age up to 2.3-2.9 points according ISS scale. The established medical demographic characteristics of victims of elderly age condition necessity of development of differentiated approaches to their medical care support, planning of measures of population prevention of medical sanitary aftermaths of road traumatism.

[Biological activity of interferons in the novel coronavirus infection COVID-19].

INTRODUCTION: The immunopathogenesis of the novel coronavirus infection COVID-19 is usually associated with the development of imbalance in the immune response to its causative agent, SARS-CoV-2 virus (Coronaviridae: Coronavirinae: Betacoronavirus: Sarbecovirus). This is manifested, in particular, by interferons' (IFNs) deficiency at the beginning of the disease followed by hyperproduction of pro-inflammatory cytokines. The virus causes a decrease in IFN types I (α/ß) and III (λ) levels; changes in IFN type II (γ) are less studied. In this regard, it is relevant to assess the functional bioactive IFN (interferon status) in COVID-19. The aim of the study was to assess the antiviral potential of the body by testing the biologically active IFNs in COVID-19. MATERIAL AND METHODS: We used biological serum samples of COVID-19 patients taken in the acute phase (110 patients on the 1-5 days of the disease) and during rehabilitation (47 patients during 1-3 months after the disease onset). Assessment of interferon status was performed according to the technique developed by the authors and described earlier. RESULTS: The IFN status of patients with COVID-19 in the acute period and in the phase of post-infection rehabilitation was studied вduring the observation period. It was found that SARS-CoV-2 causes a pronounced inhibition of biological activity of IFN types I and II compared to the reference values by more than 20 and 7 times, respectively. During the post-COVID period, incomplete recovery of the IFN system activity was registered, which proceeded very slowly. No cases of reaching physiological indicators of interferon status were identified during the observation period. CONCLUSION: The obtained data on deficiency of the functional biologically active IFN confirm the hypothesis about the predominant role of impaired IFN production of different types in the immunopathogenesis of the novel coronavirus infection.

[Invasive mucormycosis affecting maxillofacial region in oncohematological patients undergoing chemotherapeutic treatment and transplantation of hematopoietic stem cells]. / Invazivnyi mukormikoz s porazheniem organov chelyustno-litsevoi oblasti u onkogematologicheskikh bol'nykh na fone khimioterapevticheskogo lecheniya i transplantatsii gemopoeticheskikh stvolovykh kletok.

The aim of the work is to attract the attention of specialists: dentists, oncologists, hematologists to thorough sanitation of the oral cavity of patients preparing for chemotherapy treatment, to transplantation of hematopoietic stem cells. Two clinical cases described in the article were observed at the R.M. Gorbacheva First Saint-Petersburg State Medical University from 2010 to 2019. They confirm the possibility of the occurrence of infectious complications with damage to the maxillofacial region caused by rare pathogens of invasive mycosis, which debuted as an odontogenic inflammatory process. The success of the treatment of Invasive Mycosis depends on early diagnosis and antimycotic therapy; active surgical tactics in relation to the affected tissues in a controlled course of the underlying disease and the restoration of effective hematopoiesis.

[The development of first medical care support to victims of road traffic accidents: The publications review].

The medical and demographic losses because of road traffic accidents continue to be significant in most of economically developed and developing countries. The national strategies of reducing medical and demographic losses include two groups of measures, depending on object of exposure: (1) targeted to decreasing risk of road traffic accidents and (2) targeted to timely and adequate medical care support of victims. Beyond this classification are activities targeted to developing and improving in participants of road traffic skills of first self-care and mutual assistance. The availability of mentioned skills is important for saving lives and preventing permanent disability of victims of road traffic accidents.

[Non-Langengars type of sinus histiocytosis with maxillofacial skin lesions (Rosai-Dorfman disease). Clinical case description]. / Sinusovyi gistiotsitoz nelangengarsnogo tipa s porazheniem kozhi chelyustno-litsevoi oblasti (bolezn' Rozai­Dorfmana). Klinicheskoe nablyudenie.

In maxillofacial surgery, there are periodic cases of long-lasting chronic inflammation of the soft tissues without the positive effect of the conservative treatment. In these cases, questions arise of a detailed analysis of the etiology and pathogenesis of the disease, differential diagnosis of the pathological process, including those rarely encountered in the practice of a maxillofacial surgeon. One of these diseases is Rosai Dorfman's disease, which refers to extranodal histiocytosis. In domestic and foreign literature, single clinical observations are found without a detailed analysis of the diagnostic algorithm and the choice of treatment tactics. This article presents a clinical case of Rosai-Dorfman disease of a 55-year-old patient with a lesion of the soft tissues of the maxillofacial region. The described case took place in the clinic of maxillofacial surgery of the Research Institute of Dentistry of Surgical and Maxillofacial Surgery PSPbGMU named after academician I.P. Pavlova in the period from 2016 to 2019. Given the complexity of the diagnosis of this rare nosological form, we offer a specific examination algorithm that leads to a multidisciplinary comprehensive approach from disease verification to the choice of treatment tactics.

[Evaluation of the relationship between the parameters of peripheral skeletal and respiratory muscles in patients with chronic obstructive pulmonary disease].

Chronic obstructive pulmonary disease (COPD) is a group of diseases with high levels of comorbidity. Pathological changes of peripheral skeletal and respiratory muscles in COPD patients, which are often underestimated, occupy a special place. AIM: To study the relationship between functional and quantitative parameters of the peripheral (limb muscle) and respiratory muscles in COPD patients. MATERIALS AND METHODS: 127 patients (98 men/29 women, mean age 67.68.2 years) were under observation without acute COPD. All COPD patients were classified according to GOLD (2019) into groups A, B, C, D. The algorithm of the European Working Group on Sarcopenia in Older People (EWGSOP2) was used to diagnose sarcopenia. The muscle mass was measured using dual energy X-ray absorptiometry (DXA) and the appendicular lean mass index (ASM) was estimated. Maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) were measured by body plethysmograph MasterScreen Body. Quantitative assessment of thoracic muscle cross-sectional areas were performed using the CT scan using Vidar Dicom Viewer software. RESULTS: Sarcopenia was diagnosed in 43.3% of COPD patients. Respiratory muscle dysfunction was determined in 66.1% of patients with COPD, its probability increased in groups C and D in comparison with groups A and B [chance ratio 6.6 (95% confidence interval 2.915.0); p0.0001]. Correlations between the functional parameters of sarcopenia and respiratory muscle strength as well as between the mass of peripheral skeletal muscles and respiratory muscle area have been established according to the data of computerized tomography (р0.01). Sarcopenia as well as respiratory muscle dysfunction was observed more frequently in persons with severe and extremely severe airway obstruction and in patients with predominantly emphysematic COPD phenotype (p0.01). CONCLUSION: Sarcopenia is a frequent comorbidity in COPD and its development is connected with the severity of the course of the main disease. Correlation between parameters of peripheral (limb muscle) and respiratory muscles in patients with COPD has been determined.

Deregulation of Selected MicroRNAs in Sinonasal Squamous Cell Carcinoma: Searching for Potential Prognostic Biomarkers.

Sinonasal carcinomas are head and neck tumours arising from the nasal cavity and paranasal sinuses characterized by unfavourable outcome, difficult treatment, diagnosis and prognosis. MicroRNAs are key molecules in the regulation of development and progression of cancer and their expression profiles could be used as prognostic biomarkers, to predict the patients' survival and response to treatment. In this study, we used quantitative real­time PCR with TaqMan® Advanced miRNA Assays to investigate the relative expression values of selected micro- RNAs in a unique set of formalin-fixed paraffin-embedded tissue samples obtained from 46 patients with sinonasal squamous cell carcinoma. Our results showed statistically significant up-regulation of three mature microRNAs: miR-9-5p (fold change: 6.80), miR-9-3p (fold change: 3.07) and let-7d (fold change: 3.93) in sinonasal carcinoma patients. Kaplan-Meier survival analysis and logrank test identified association between higher expression of miR-9-5p and longer survival of the patients (P = 0.0264). Lower expression of let-7d was detected in the patients with impaired survival, and higher expression of miR-137 was linked to shorter survival of the patients. We also identified several correlations between expression of the studied microRNAs and recorded clinicopathological data. Higher expression of miR-137 and lower expression of let-7d correlated with local recurrence (P = 0.045 and P = 0.025); lower expression of miR-9-5p and higher expression of miR-155-5p correlated with regional recurrence (P = 0.045 and P = 0.036). Higher expression of miR-9-3p correlated with occupational risk (P = 0.031), presence of vascular invasion (P = 0.013) and perineural invasion (P = 0.031). Higher expression of miR-155-5p was present in the samples originating from maxillary sinus (P = 0.011), cN1-3 classified tumours (P = 0.009) and G2-3 classified tumours (P = 0.017). In conclusion, our study supports the hypothesis of future prospect to use expression of miRNAs as prognostic biomarkers of squamous cell sinonasal carcinoma. In particular, miR-9-5p and miR-9-3p seem to be important members of the sinonasal cancer pathogenesis.

[The use of the functional state of the joints for the estimation of the effectiveness of the application of oxygen/ozone therapy for the rehabilitative treatment of the patients suffering from knee arthritis]. / Funktsional'noe sostoianie sustavov kak kriterii otsenki éffektivnosti ispol'zovaniia ozonoterapii v vosstanovitel'nom lechenii bol'nykh gonartrozom.

BACKGROUND: In the recent years, the ever increasing tendency toward the growth in the prevalence of degenerative-dystrophic articular diseases has been observed especially among the young subjects and the middle-aged people. The enhanced economic burden of treating the patients with this condition on the public health care system frequently comes not only from chronic pathology of the joints but also from the development of concomitant disorders which dictates the necessity of the search for the new methods for the management of such patients. AIM: The objective of the present study was the optimization of the treatment of the patients presenting with stage I-II gonarthrosis by the para-articular application of oxygen/ozone therapy at the early stages of knee arthritis and the evaluation of the clinical effectiveness of this approach. MATERIAL AND METHODS: A total of 89 patients suffering from I-II sg gonarthrosis were recruited for the participation in the study. They included 67.2% of men and 32.8% of women. The age of the patients varied from 33 to 54 (mean 42±5) years, the duration of the disease averaged 4±1.2 years. All the patients were randomly divided into two groups: matched for the age, gender, the duration and severity of the disease, and the methods of its treatment. The main group was comprised of 45 patients whereas the group of comparison consisted of 44 patients. The generally accepted therapeutic modalities were used to treat the patients of both groups. Those included in the main group (n=45) additionally received para-articular oxygen/ozone therapy applied to the affected knee at a permanent ozone concentration of 8 gr/l (the injection area 15-20 sq.cm), main group n=45). The results of the treatment were evaluated within 1 and 6 months after the onset of therapy. RESULTS: The application of the up-to-date methods of oxygen/ozone therapy in the combination with the universally-accepted drug-based treatments for the patients of the main group resulted in the significant (p<0.01) improvement of the indicators of the biomechanical activity of the knee joints in comparison with that achieved by means of the generic drug-based treatment alone. DISCUSSION: The results of the present study give evidence of the feasibility of application of oxygen/ozone therapy for the treatment of degenerative-dystrophic articular diseases of the knees. The positive dynamics of the indicators of the functional activity of the knee joints, intensity and duration of the pain syndrome as well as the reduction of the period of the temporary incapacity for work associated with exacerbation of knee arthrosis suggests the high clinical and economic effectiveness of the para-articular application of oxygen/ozone therapy. CONCLUSIONS: The present study has demonstrated the expediency and effectiveness of the application of oxygen/ozone therapy during exacerbation of stage І-ІІ knee arthritis as evaluated based on the WOMAC index, VAS, and Lyshom scale within one and six months after the onset of the treatment. The resulting reduction in the number of days of temporary incapacity for work in the patients suffering from knee arthritis gives evidence of the clinical and economic validity of the proposed method of the combined treatment of this condition based on the application of oxygen/ozone therapy.

Pulmonary vasculitis: diagnosis and treatment.

Pulmonary vasculitis is a group of rapidly progressing severe diseases characterized by vascular inflammation, destruction and necrosis of the pulmonary tissue. The pathological process in the lungs varies from diffuse alveolar hemorrhage to inflammation of the parenchyma, pleural effusion, thrombotic and thromboembolic complications. Depending on the size of the affected vessels, vasculites are divided into vasculites of large, medium and small vessels. Most frequently the lung is found in the small vessels vasculitis, including ANCA-associated vasculitis [granulomatosis with polyangiitis (GP), eosinophilic granulomatosis with polyangiitis (EGPA) and microscopic polyangiitis (MPA)] and the disease is glomerular basement membrane (goodpasture syndrome). Clinical examination of other systems and organs involved in the pathological process, including the skin and kidneys, as well as the detection of autoantibodies can improve approaches to early diagnosis and treatment of vasculitis. Treatment of life-threatening pulmonary bleeding and irreversible damage to organs, especially the kidneys, requires rapid diagnosis of these conditions. Vasculitis is a rare disease with lesions of many organs, and methods of their treatment, including biological, are rapidly developing, which requires the cooperation of doctors of various specialties and specialized centers to achieve better control of the disease.

[Analysis of the state-of-the-art of consulting medical care to patients with glucocorticoid-induced osteoporosis or its risk according to the data of a questionnaire survey (GLUCOST study)].

AIM: To analyze the state-of-the-art of consulting medical care to Russian patients with glucocorticoid-induced osteoporosis (GCOP) or its risk. SUBJECTS AND METHODS: This GLUCOST study was organized and conducted by the Russian Association of Osteoporosis. A total of 1129 patients with chronic inflammatory diseases, who had been taking oral glucocorticosteroids (OGCSs) a long time (3 months or more), were examined. The patients filled out an anonymous questionnaire on their own. Whether the measures taken to diagnose, prevent, and treat GCOP complied with the main points of Russian clinical guidelines was assessed. RESULTS: 61.8% of the patients knew that the long-term treatment of GCOP might cause osteoporosis. 48.1% of the respondents confirmed the results of bone densitometry; 78.1% of the patients reported that they had been prescribed calcium and vitamin D supplements by their physician, but their regular intake was confirmed by only 43.4%; 25.4% of the patients had sustained one low-energy fracture or more. Treatment for GCOP was prescribed for 50.8% of the patients at high risk for fractures, but was actually received by 40.2%. Therapeutic and diagnostic measures were implemented in men less frequently than in women. When the patient was aware of GCOP, the probability that he/she would take calcium and vitamin D supplements rose 2.7-fold (95% Cl; 2.1 to 3.5; p = 0.001) and that he/she would follow treatment recommendations did 3.5-fold (95% Cl; 2.3 to 5.3; p = 0.001). Bone densitometry increased the prescription rate for antiosteoporotic medication and patient compliance. CONCLUSION: According to the data of Russia's large-scale GLUCOST survey, every four patients with chronic inflammatory disease who are on long-term OGCS therapy have one low-energy fracture or more. Due to inadequate counseling, the patients are little aware of their health and do not get the care required to prevent the disease. Less than 50% of patients who have GCOP and a high risk for fractures undergo examination and necessary treatment aimed at preventing fractures.

[Choice of basic therapy for asthma in real clinical practice].

According to the Global Initiative for Asthma, the treatment of asthma should be mainly based on its control that encompasses symptom control and exacerbation risk reduction. Control-based treatment contributes to decreases in the frequency of exacerbations, the incidence of drug side effects, the needs of asthmatic patients for emergency care, and the number of their visits to a doctor and hospitalizations, resulting in a reduction of direct health care costs of asthma. Drugs for the basic therapy of asthma are chosen on the basis of evidence for their efficacy and safety and the view of availability and cost of treatment. In case of poor asthma control it is important to reveal its causes and to change basic therapy according to the individual needs of the patient. A major role in the achievement of asthma control is assigned to a combination of inhaled glucocorticosteroids (ICS) and long-acting ß2-agonists. Combined medications are prescribed to asthma patients in accordance with the daily ICS dose required to achieve asthma control.

[Comparative analysis of the effectiveness of antiviral therapy of children with infectious mononucleosis].

A group of 126 children (4 to 7 years old) with infectious mononucleosis received basic therapy in combination with nonspecific antiviral drugs. The same therapeutic efficiency was observed for cycloferon and genferon light included in complex treatment of infectious mononucleosis in children. The use of cycloferon (10 mg/kg i.m., single daily injection for 10 days) prevents the development of frequent acute respiratory viral infections in the period of convalescence.
