Drug-induced liver injury: diagnosis of exclusion
Abstract
Drug-induced liver injury (DILI) is a relevant issue in clinical practice and is still a diagnosis of exclusion. Despite the low incidence in the general population, DILI is the cause of most cases of acute hepatic injury and has a mortality rate of up to 50%. Despite many reports in the medical literature about the DILI mechanisms, a clear causal relationship between them, drugs, and risk factors has not been established. Current clinical practice is based on a combination of a thorough study of a history of risk factors, the timing of drug and dietary supplements' administration, and the analysis of laboratory and instrumental tests. It aligns with the international criteria of the Rousell Uclaf Causality Assessment Method (RUCAM), which is considered one of the main diagnostic algorithms for DILI. The article addresses current DILI classification, risk factors, diagnostic algorithms, causalities, clinical evaluation, promising liver function biomarkers, and specific treatment.

Particularities of arterial stiffness dynamics on the background of breast cancer chemotherapy
Abstract
Background. Modern breast cancer chemotherapy regimens (BC) consider individual patient parameters and ranges of cardiotoxic doses. However, clinicians often record clinical and laboratory-instrumental signs of cardio- and vasculotoxicity in patients, which emphasizes the high importance of searching for markers of early toxic response.
Aim. To study the characteristics of the response of arterial stiffness on the background of anthracycline-containing chemotherapy to determine potential markers of vasculotoxicity in BC patients.
Materials and methods. 20 women with a BC were included. The patients received 4 cycles of chemotherapy in the doxorubicin + cyclophosphane (AC) regimen with an interval of 2–3 weeks, then they were injected with paclitaxel weekly for 12 injections, or docetaxel once every 3 weeks. All patients underwent TTE, arterial stiffness determination by the "gold standard" method and using volumetric sphygmography before the start of treatment, after the completion of the anthracycline component and after the end of taxanes.
Results. The average age of the patients was 45.5±5.31 years. After completing the course of anthracyclines, there was a significant increase in heart rate (from 65.6±9.3 to 73.3±10.1 beats/min.), a decrease in SBP (from 122.6±9.9 to 116.5±12.3 mmHg) and DBP (from 78.9±8.5 to 76.2±8.6 mmHg), a decrease in carotid femoral pulse wave velocity (cfPWV) (from 9.32±1.41 to 7.85±1.57 m/s), CAVI index on the left (from 6.78±0.81 to 6.5±0.88), the velocity of the cardio-ankle pulse wave on the right and left (from 6.7±0.6 to 6.5±0.7 m/s; from 7.0±0.6 to 6.3±0.8 m/sc, respectively). After the completion of the taxane, there was a tendency to increase these indicators, however, they remained significantly lower compared to the values before the start of treatment.
Conclusion. A comparative analysis of arterial stiffness indicators at different stages of chemotherapy showed a more pronounced reaction of cfPWV, CAVI, cardio-ankle pulse wave to the administration of anthracyclines, which presumably may be associated with concomitant hemodynamic restructuring.

Drug therapy’s new options in the treatment of the severe irritable bowel syndrome
Abstract
Background. Stress, individual characteristics of each patient, visceral hypersensitivity and intestinal motility have the key importance in the pathogenesis of irritable bowel syndrome (IBS). In recent years, there has been growing interest in the use of selective serotonin and norepinephrine reuptake inhibitors (SNRIs) in the complex therapy of IBS patients with somatoform disorders.
Aim. To examine the effectiveness of the SNRIs antidepressant therapy in the treatment of patients with IBS and diarrhea (IBS-D) with extraintestinal manifestations.
Materials and methods. 42 patients with severe IBS and diarrhea (IBS-D) were examined, among them 22 female with a median age of 32 years old (22; 38), and 20 male with a median age of 31 years old (25; 35). Treatment with duloxetine 60 mg/day was prescribed. The effectiveness of the therapy was assessed after eight weeks. The IBS clinical symptoms dynamics were assessed by the intensity of pain syndrome and bloating, which were determined using Visual Analogue Pain Scale (VAS), stool frequency and shape based on the Bristol stool scale; Visceral sensitivity threshold was assessed according to the Balloon dilatation test. There was studied the effect of the duloxetine on the extraintestinal manifestations of IBS. The psycho-emotional state was assessed using the Beck scale of anxiety and depression and the Spielberger–Khanin scale by psychiatrist, neurologist-vegetol.
Results. All patients showed positive dynamics after eight weeks duloxetine treatment: the decrease of pain syndrome from 9 (9; 10) to 2 (2; 3) points, bloating from 8 (8; 9) points to 2,5 (1; 3) points according to VAS, and defecation frequency from 10 (9; 12) to 2 (1; 2) times a day; the change of stool consistency from 6th (6; 7) to 3rd (3; 4) type. The visceral sensitivity threshold increased: the time of appearance of the first urge to defecate increased from 56 (34; 74) ml to 95 (80; 98) ml. Significantly decreased extraintestinal manifestations of IBS. In reassessing each patient’s individual characteristics there were the decrease of the depression level according to the Beck scale from 26 (23; 32) to 11.5 (10; 13) points and personal personal anxiety level according to the Spielberger–Khanin scale from 42.5 (35; 53) to 22 (20; 24) points, as well as the decrease of situational anxiety from 40 (37; 49) to 22 (21; 36) points.
Conclusion. The severe course of IBS-D is mainly associated with the patients’ individual characteristics and anxiety or anxiety-depressive syndromes. The positive impact of duloxetine therapy in severe IBS-D with extraintestinal manifestations is associated with the regulation of serotonergic and noradrenergic activity of the central.

Use of a controlled attenuation parameter for the diagnosis of non-alcoholic fatty liver disease
Abstract
Aim. To evaluate the efficacy of vibration-controlled transient elastography (VCTE) with a controlled attenuation parameter (CAP) in a population of patients with non-alcoholic fatty liver disease (NAFLD)and to compare to US and different non-invasive indices.
Materials and methods. Single center NAFLD patients’ database of 2021–2023 years was retrospectively analysed. Data of VCTE evaluation with CAP (FibroScan 530® and FibroScan 630 Expert®) as well as liver US examination results and values of HSI, FLI, BAAT and NAFLD-LFS were extracted. AUROCs for all methods used were constructed and sensitivity and specificity analysis was performed.
Results. The data of 1081 patients were available for analysis (385 with steatosis, 274 with NASH, 422 without NAFLD as a control). Ultrasound examination in the diagnosis of liver steatosis compared to VCTE with CAP showed sensitivity and specificity of 94.6 and 63.7%, respectively. Diagnosis of liver steatosis using indices and scales showed sensitivity and specificity of HSI: 97.9 and 60.1% (AUROC 0.90), FLI: 92.5 and 85.3% (AUROC 0.93), BAAT: 76.6 and 73.5% (AUROC 0.82), NAFLD-LFS: 56.7 and 81.8% (AUROC 0.85).
Conclusion. The sensitivity of the US of the liver was consistent with previous studies, but the specificity was low. The HSI index had the best indicators of sensitivity and specificity in relation to the diagnosis of liver steatosis. Combination of liver US and HSI can be used in screening of liver steatosis, however, for the complete diagnosis better tools which can simultaneously evaluate liver steatosis and fibrosis should be used.

Assessment of body mass index in patients with chronic hepatitis C who received an effective antiviral therapy
Abstract
Aim. To evaluate the body mass index (BMI) in patients with chronic hepatitis C (CHC) with different stages of liver fibrosis and steatosis who received effective antiviral therapy (AVT).
Materials and methods. The study included 278 CHC patients with a sustained virologic response (SVR) at the end of treatment. In addition to assessing the investigational data to determine the clinical status of the patient, we calculated BMI (following the World Health Organization guidelines) and determined the severity of liver fibrosis (F) and steatosis (S) using transient elastography. The patients were assessed at the start of antiviral therapy, after ≥6 months from the moment SVR was confirmed, and then every 12 to 24 months.
Results. By the end of the study, the mean patient age was 49 years, 53% of them were men, and 34% of the patients were obese. Excessive weight gain was registered in 17% (n=48) of the cases, with 60% newly diagnosed with Class 1 to 2 obesity. Both before the start of AVT and years after reaching SVR, the mean BMI corresponded to the reference pre-obesity values, the liver steatosis was significantly more often absent in normal BMI; on the contrary, fatty liver (predominantly S2 to S3) was registered in individuals with elevated BMI (p<0.0001). After the long-term period following a successful therapy, Stage F4 liver fibrosis patients were mainly diagnosed with obesity (80% versus 44% before AVT; p=0.0010).
Conclusion. The high proportion of patients with elevated BMI and liver steatosis seen years after a successful CHC therapy indicates a continued risk of progression of chronic liver disease. Such patients should be advised on how important it is to change their lifestyle to reduce overweight and prevent weight gain. We also need long-term assessments of how liver steatosis changes over time and what are the outcomes associated with post-SVR increase in BMI.

The role of structure-modifying agents in the treatment of back pain
Abstract
Background. Back pain is currently one of the most urgent problems within pain syndromes. Inadequate treatment of nonspecific back pain, even with a relatively favorable prognosis, leads to its chronicity and decreases the patient's quality of life. The most common cause of vertebrogenic dorsopathies is spinal osteochondrosis. The etiopathogenetic basis of spinal osteochondrosis is degenerative and dystrophic changes in the intervertebral discs involving adjacent vertebrae, joints, and ligaments. Considering the experience of many years of using chondroprotective therapy in clinical practice, we performed an observational study using Ambene Bio to assess the change of pain severity over time in patients with osteochondrosis and back pain.
Aim. To study the change in the severity of pain and its components in patients with back pain during therapy with Ambene Bio combined with standard therapy (NSAIDs and muscle relaxants).
Materials and methods. Fifty-one patients with chronic lower back pain lasting more than 3 months were included in the study.
Conclusion. The study results confirmed the high efficacy of Ambene Bio in patients with dorsopathies with an alternating treatment regimen (10 IM injections 2 mL every other day).

Opportunities to improve the prognosis of the course of COVID-19 for at-risk patients
Abstract
Aim. To evaluate the efficacy and safety of a combination of virus neutralizing monoclonal antibodies in the treatment of patients with confirmed COVID-19 and risk factors for disease progression and severe disease course.
Materials and methods. The study was carried out in the Sokolniki temporary hospital of the Inozemtsev City Clinical Hospital. A retrospective comparative case-control study included 400 patients hospitalized for confirmed COVID-19 infection from November 01, 2022 to March 31, 2023. Patients were divided into two groups depending on the treatment given: the first control group (n=200) and the second group (n=200), where patients received a single intramuscular injection of tixagevimab + cilgavimab within the first days of hospitalization.
Results. When analyzing the concomitant pathology, C-reactive protein level and CT scans at the time of hospitalization, it was revealed that patients in the tixagevimab + cilgavimab treatment group were more severe compared to the control group. On the 2nd day of hospitalization, there was a decrease in the level of C-reactive protein in the control group by 36.2%, in the group receiving tixagevimab + cilgavimab – by 45.2%; p<0.05. Standard treatment was supplemented with antibacterial therapy in 47 (23.5%) patients of the first group and in 32 (16.0%) patients of the second group, which was due to the accession of bacterial infection; p<0.05. Significant differences were found in the duration of hospitalization, which averaged 8.0±0.21 bed-days in group 1 and 6.4±0.13 (p<0.05) bed-days in group 2. No adverse reactions to intramuscular injection of tixagevimab + cilgavimab were detected.
Conclusion. The use of a combination of neutralizing monoclonal antibodies in patients with COVID-19 reduce the average bed-day in hospitalization of patients with comorbid pathology and/or immunodeficiencies and high risk of progression of infection.

Cardiovascular risk factors in patients with ulcerative colitis
Abstract
Background. Given the current trends in increasing the life expectancy of patients with ulcerative colitis (UC), the study of the risk of atherothrombotic events in them requires study. For effective prevention of cardiovascular diseases, it is necessary to assess cardiovascular risk factors since the concept of their timely detection is the basic one when planning preventive measures.
Aim. To assess the prevalence of cardiovascular risk factors in patients with UC.
Materials and methods. One hundred eighty four UC patients participated in the case-control study; 56 participants were included in the control group. The studied parameters are unmodified, behavioral, and biological factors of cardiovascular risk. The study participants were surveyed, examined, measured blood pressure, height, weight, the level of total cholesterol was studied, and the lipid spectrum was analyzed in 80 patients with UC. Parametric and nonparametric statistical methods were used.
Results. UC patients consumed fruit less often, drank tea and coffee with sugar more often, exercised less often and experienced high levels of stress. A higher incidence of arterial hypertension in UC patients was established, even though the fact of taking glucocorticosteroids was considered. No significant differences were found in the assessment of relative and total cardiovascular risk.
Conclusion. Risk management of cardiovascular diseases in UC patients should focus on a personalized approach and timely screening of modifiable cardiovascular risk factors with their subsequent correction. The absence of significant differences in the level of relative and total cardiovascular risk indicates a limited contribution of traditional risk factors to the development of cardiovascular diseases in UC patients.

Abstract
Background. The problem of recurrent urinary tract infections (UTI) in patients with type 2 diabetes mellitus (DM 2) is relevant, especially when there is a combination of predisposing factors, such as female gender, history of UTI episodes, and therapy with sodium glucose cotransporter type 2 (SGLT-2) inhibitors, and the choice of effective and safe means could cause some difficulties, including ina terms of the burden of antibiotic resistance.
Aim. To evaluate the effectiveness and safety of the phytoproduct Canephron® N for the prevention of exacerbations of recurrent cystitis and the effect on metabolic parameters in patients with type 2 diabetes taking SGLT-2 inhibitors.
Materials and methods. Prospective, randomized, open, parallel group study in 60 women. The main group took the drug Canephron® N for 3 months. The main parameters for evaluating were the frequency of recurrence of cystitis, level of albuminuria and LDL-cholesterol peroxidation product – malondialdehyde.
Results. Within 3 months of taking Canephron® N, exacerbations of chronic cystitis were diagnosed 2 times less often, a decrease in albuminuria was found in the form of an increase in the proportion of patients with an optimal level of albuminuria by 20%, a 50% reduction in the frequency of the initial increase in albuminuria, and the absence of moderate albuminuria in all patients at the end of course of therapy. A decrease in the level of MDA by 1.4 times was noted (p=0.019).
Conclusion. Thus, the herbal drug Canephron® N can be used for accompanying therapy and prophylactic treatment in patients with recurrent cystitis on the background of DM 2, taking SGLT-2 inhibitors. The course of therapy should last at least 3 months.

Comparison of the effectiveness of rabeprazole original and generic products in the monotherapy of gastroesophageal reflux disease
Abstract
Aim. To compare the effectiveness of rabeprazole original and generic products in the treatment of gastroesophageal reflux disease (GERD) using impedance-pH monitoring.
Materials and methods. Patients (n=35) diagnosed with GERD were divided into two groups. Group 1 patients (n=17, 45.2±1.7 years) received the rabeprazole original product (Pariet) 20 mg/day; Group 2 patients (n=18, 48.1±1.9 years) received 20 mg/day of a generic product. On Day 10 of therapy, all patients underwent 24-hour esophagus impedance-pH monitoring (Ohmega, Medical Measurement Systems, the Netherlands). The percentage of time with pH<4 in the esophagus, the total number and number of acidic, slightly acidic and slightly alkaline gastroesophageal refluxes (GERs), the latency period, and the duration of rabeprazole action were analyzed. The clinical efficacy of the drug was assessed using the GerdQ questionnaire. Statistical data were processed using Microsoft Office 2010 (Excel) and Biostat 2000 software packages.
Results. No significant differences were noted between the two groups of patients by gender, age, body mass index, smoking frequency, and GERD type (p>0.05). The average duration of action of the rabeprazole original product was significantly higher than that of the generics (13.2±0.6 and 8.8±0.7 h, respectively, p<0.05). In the rabeprazole original product group, compared to the generics group, the following values were lower: total GERs – 47.0 [43.3; 60.0] and 71.8 [54.3; 95.0], respectively, p<0.05; percentage of time with intraesophageal pH<4 – 1.8 [0.5; 2.3] and 2.1 [0.3; 6.8], respectively, p<0.05; the number of acidic GERs – 4.7 [2.2; 12.0] and 23.3 [12.6; 32.0], respectively, p<0.05. The total GerdQ questionnaire score in Group 1 was significantly lower than in Group 2 (5.4±0.1 vs 6.9±0.4, respectively; p>0.05).
Conclusion. In treating GERD with the rabeprazole original product compared to generics, a significantly longer duration of acid production suppression, a more pronounced decrease in esophageal acidification, and a more statistically significant clinical improvement were observed.

Mild post-COVID syndrome in young patients
Abstract
Background. Many COVID-19 survivors suffer from post-COVID syndrome, which significantly worsens the quality of life. Its presentation is quite diverse, with cognitive disorders being of particular importance. Liver injury due to the direct virus action and the treatment of the new coronavirus infection can persist for a long time during the recovery period and lead to hyperammonemia, which can cause cognitive disorders, including minimal hepatic encephalopathy.
Aim. To study cognitive disorders in post-COVID syndrome and the possibility of their treatment with L-ornithine-L-aspartate.
Materials and methods. The study included 30 students from 18 to 24 years old who had COVID-19 and decreased attention, memory impairment, and other cognitive disorders inherent in hepatic encephalopathy of latent (grade 0) or mild (grade 1) severity, without pronounced impairment of intelligence, memory, speech, and learning ability. Hyperammonemia, elevated alanine aminotransferase, aspartate aminotransferase, and ã-glutamyl transpeptidase, signs of hepatic encephalopathy according to psychometric tests, were reported in young people. All patients in the study were treated with L-ornithine-L-aspartate to correct the ammonia blood level and improve signs of hepatic encephalopathy and the general condition.
Results and conclusion. An improvement in the objective findings, liver enzymes, a decrease in ammonia level, and an improvement in testing results for changes in cognitive functions were reported.

Long-term probiotic administration for irritable bowel syndrome: a legal need
Abstract
Background. Irritable bowel syndrome (IBS) is one of the most common functional diseases of the gastrointestinal tract. Violations in the intestinal microbiocenosis play a significant role in the pathogenesis of this suffering. The probiotic strain Bifidobacterium longum 35624® has a strong evidence base for use in the management of patients with IBS. The duration of probiotic therapy and the need for repeated courses of probiotics require further study, which determined the need for this observational study.
Aim. To compare the results of prolonged (12 weeks) and usual duration of courses of probiotic Bifidobacterium longum 35624® in patients with IBS.
Materials and methods. 42 patients with a verified diagnosis of IBS of moderate and severe severity who met the inclusion criteria were recruited into the study. Patients were prescribed probiotic Bifidobacterium longum 35624® at a dose of 1 capsule (1×109 CFU), 1 time per day for 12 weeks. The course of the disease was assessed using the visual analogue scale, visceral sensitivity index (VSI), IBS symptom severity scale (IBS-SSS), quality of life indicators were assessed using the IBS-QoL questionnaire scales. Evaluation of indicators was carried out at the inclusion visit, on days 14, 28, 56, 84 of probiotic intake and on day 112 (28 days after the last dose of Bifidobacterium longum 35624®).
Results. The results obtained confirmed the ability of the probiotic Bifidobacterium longum 35624® to positively influence the course of IBS. The addition of the main therapy with a probiotic made it possible to achieve a significant decrease in the severity of abdominal pain, bloating, and stool disorders. The severity of IBS significantly decreased according to the results of IBS-SSS. Reliable positive dynamics of indicators on the scales IBS-QoL, VSI is shown. The most pronounced changes were observed by the end of the third month of taking Bifidobacterium longum 35624®. Thus, according to the IBS-SSS indicators, only by the end of the third month of observation, some patients achieved remission of the disease. All described changes were persistent and persisted one month after the end of the probiotic intake.
Conclusion. The addition of a prolonged course of the probiotic Bifidobacterium longum 35624® to the basic therapy in patients with IBS allows a more pronounced and lasting effect to be achieved. A “post-probiotic” effect was shown – a decrease in VSI after the end of the intake of the probiotic strain. Given the chronic relapsing course of IBS, the use of repeated probiotic courses was proposed to prevent exacerbation of the disease.

Diagnostics and treatment of intraductal papillary mucinous pancreas neoplasm
Abstract
A clinical case of a 71-year-old patient with intraductal papillary mucinous neoplasia (IPMN) is presented. The diagnosis was established using endoscopic retrograde cholangiopancreatography, magnetic resonance imaging, computed tomography. Asymptomatic course, absence of pain syndrome, obstruction, exocrine and endocrine pancreatic failure, relatively satisfactory general health, but the presence of structural changes: an increase cyst in the head of the pancreas measuring 27×23 mm, expansion of the main pancreatic duct up to 13 mm raised doubts about the choice of treatment tactics, the need for surgical intervention. To exclude the risk of malignancy and the choice of treatment tactics, a fine-needle aspiration biopsy was performed, a cytological examination of the material, an expert opinion determined the scope of the surgical intervention. IPMN is a rather rare tumor of the pancreas. For a long time, IPMN flow “under the guise” of chronic pancreatitis. Depending on the type of degree of dysplasia and invasiveness of IPMN, the tactics of treatment and the volume of surgical intervention are determined. High-tech methods provide high information content in the diagnosis of IPMN. But only a morphological study allows you to determine the tactics of treatment.

Eosinophilic chronic obstructive pulmonary disease: A review
Abstract
Over the past decades, chronic obstructive pulmonary disease (COPD) has become a major public health problem due to increasing morbidity and mortality. COPD is characterized by airflow limitation due to inflammation of the bronchial tree and remodeling of the small airways. In 20–40% of patients with COPD, eosinophilic inflammation of the airways is observed, as in bronchial asthma. Eosinophilic COPD has recently been shown to be a distinct disease and is associated with more pronounced airway remodeling. Although the role of eosinophils in the pathogenesis of COPD is not fully understood, the level of eosinophils can be used in the prognosis and administration of corticosteroids, and their effectiveness is higher in eosinophilia. Currently, monoclonal antibodies directed against interleukins (IL-5, IL-4 and IL-13) or their receptors are being tested in the T2 endotype of COPD. This review focuses on the mechanisms of eosinophilia in COPD, the use of blood and sputum eosinophils as a biomarker, and the advisability of using monoclonal antibodies in the treatment of eosinophilic COPD.

Clinical effectiveness and pharmacokinetics of gliflozin from the point of view of individual genetic characteristics: A review
Abstract
A review of publications devoted to the analysis of genetic polymorphisms and features of the functioning of genes that affect the pharmacokinetics and pharmacodynamics of sodium-glucose cotransporter-2 inhibitors (SGLT2i) is presented. Objective of the study was to reveal information about genes whose polymorphism may affect the effectiveness of SGLT2i. The review was carried out in accordance with the PRISMA 2020 recommendations, the search for publications was carried out in the PubMed databases (including Medline), Web of Science, as well as Russian scientific electronic libraries eLIBRARY.RU from 1993 to 2022. Polymorphisms in the structure of several genes (SLC5A2, UGT1A9, ABCB1, PNPLA3) have been described that may affect the treatment of type 2 diabetes mellitus complicated by diseases such as chronic heart failure, chronic kidney disease, or non-alcoholic fatty liver disease. The information found on the genetic features of the development of the effects of SGLT2i is limited to a description of the differences in their pharmacokinetics. The relevance of currently available pharmacogenetic studies is largely constrained by small sample sizes.

Anxiety in subjects with cardiovascular disease: Current diagnostic strategies and therapeutic options. A review
Abstract
Anxiety and anxiety disorders are important modifiable risk factors for cardiovascular and other common chronic non-communicable diseases and complications. Anxiety disorders significantly reduce the motivation and adherence of patients to lifestyle changes and drug therapy, significantly worsen the quality of life, and increase the risk of disability and the costs of the health care system. The issues of diagnosis and therapy of anxiety are relevant for the practice of physicians and cardiologists due to the high incidence of anxiety disorders in patients with cardiovascular diseases, a decrease in the quality of life and an increase in adverse outcomes, and also due to the insufficient awareness of the risks associated with the psycho-emotional state of patients. Therapy of anxiety disorders includes both drug and non-drug methods. The first-line drugs in treating most anxiety disorders are selective serotonin reuptake inhibitors or selective serotonin-norepinephrine reuptake inhibitors. The risk of possible side effects of these agents in patients with cardiovascular diseases should be considered. Sedative and anti-anxiety drugs, including non-benzodiazepine tranquilizers, are more commonly used. The most studied drug from this class in therapeutic and cardiological practice is fabomotizole. The efficacy and safety of fabomotizole, including long-term use, have been studied in numerous studies in patients with cardiovascular diseases and a wide range of anxiety disorders.

Current status and prospects of using the prokinetic acotiamide in gastroenterology: A review
Abstract
Acotiamide is a prokinetic with a novel mechanism of action – an antagonist of muscarinic M1 and M2 receptors and an acetylcholinesterase inhibitor. Acetylcholine is the central mediator of the tone of the muscular components of the gastrointestinal tract, increasing its motor activity. Blockade of presynaptic M1 and M2 receptors neutralizes the inhibitory effect of the feedback mechanism on the acetylcholine synthesis, while inhibition of acetylcholinesterase in the synaptic cleft reduces the acetylcholine degradation. Currently, the clinical efficacy of acotiamide in the population of patients with functional dyspepsia is demonstrated in more than 10 clinical studies in different regions of the world, demonstrating a reduction of the symptoms of the disease during treatment with this agent and an improvement in the quality of life of patients. In addition, the combination of acotiamide with proton pump inhibitors optimizes the management of patients with gastroesophageal reflux disease.

Moscow scientific schools on the field of internal medicine in the second half of the XIX – early XX centuries: comparative characteristics
Abstract
Peculiarities and comparative characteristics of three main Moscow schools on the field of internal medicine of the second half of the XIX – early XX centuries are discussed: schools of Grigory Zakharyin, Alexey Ostroumov and Vassily Shervinsky – Leonid Golubinin; the legitimacy to acknowledge scientific clinical schools of Mikhail Cherinov and Nikolay Golubov is disputed. The arguments are provided that of the Moscow therapeutic schools, it was the Shervinsky–Golubinin school, and not the Zakharyin or Ostroumov school, that played the most significant role in the formation of the internal medicine in the USSR, in passing the accumulated knowledge and ideas to therapeutic elites in the USSR.
