Aim. An appraisal of practitioners with chronic constipation management details in older and senile adults.
Key points. Chronic constipation is a common issue in geriatrics. Aside to age-related physiological bowel disfunction, a higher constipation incidence is conditioned by declined physical activity and frailty, polypharmacy and a series of secondary constipation-developing chronic states and diseases. Chronic constipation is associated with a higher risk of cardiovascular disease and complications, impaired general perception of health and pain, growing alarm and depression, and reduced quality of life. The treatment tactics in chronic constipation is cause-conditioned and should account for the patient’s history and therapy line, overall clinical condition, cognitive status and functional activity level. An essential baseline aspect of constipation management is apprising the patient and his family of the underlying factors and methods for non-drug and drug correction. An higher-fibre diet is recommended as first measure, with osmotic laxatives added and titrated to clinical response if none observed towards the non-drug and high-fibre regimens. Stimulant laxatives and prokinetics should be recommended in patients reluctant to fibre supplements and osmotic laxatives. Subsidiary correction includes biofeedback, transanal irrigation, acupuncture, foot reflexology and percutaneous tibial nerve stimulation.
Conclusion. Elderly and senile chronic constipation is a prevalent multifactorial state requiring an efficient management via assessment and correction of total risk factors and consistent use of non-medication and drug therapies.

Aim. A study of the overlap syndrome of uninvestigated dyspepsia and heartburn at an industrial hub city of Eastern Siberia.
Materials and methods. A total of 1,382 subjects (684 men and 698 women, mean age 40.6 years) were randomly selected and examined for the central district of Krasnoyarsk. The clinical check-up and interviewing results were registered with a standard questionnaire. Heartburn was diagnosed as per the Montreal Consensus. Since no endoscopic patient examination had been performed, dyspepsia was assumed uninvestigated. Dyspepsia was diagnosed as per the Rome IV criteria. The study conduction complied with ethical standards. Each participant signed an informed examination consent, in accordance to the regulations by the World Medical Association’s Declaration of Helsinki. The survey data were analysed with common statistical methods.
Results. Heartburn, uninvestigated dyspepsia and their overlap syndrome had prevalence of 12.4, 21.1 and 5% in study population, respectively. Uninvestigated dyspepsia was registered in 40.4% patients with and 18.4% — without heartburn (p < 0.001). The risk factors of overlap syndrome were age >40 years (p = 0.002), obesity (p = 0.002), nonsteroidal anti-inflammatory drug and/or aspirin intake (p = 0.004) and tobacco smoking (p = 0.007). Among total patients with the heartburn/uninvestigated dyspepsia overlap syndrome, only 33.3% systemically had proton pump inhibitors, and only 17.4% had a prokinetic therapy.
Conclusion. The heartburn/uninvestigated dyspepsia overlap syndrome is an actual issue in the Krasnoyarsk population. Attention is warranted to this problem to optimise treatment and prevention measures.
Introduction. Hyperammonaemia develops both in cirrhosis and earlier fibrotic stages during metabolic-associated fatty liver disease (MAFLD). Besides neurotropic, ammonia exerts the hepatotoxic and profibrotic effects. L-ornithine-L-aspartate (LOLA) has been proved effective in treatment for hyperammonaemia in cirrhosis patients.
Aim. An impact study of the LOLA course therapy on inflammation, steatosis and liver fibrosis biomarkers in MAFLD.
Materials and methods. A total of 90 patients were divided between two cohorts. The control cohort included patients with liver steatosis S0–S1, absent liver fibrosis, normal liver function tests, clean history of liver disease, while MAFLD cohort gathered liver steatosis S2–S3 and METAVIR fibrosis F1. Steatosis and fibrosis were assessed with a Fibroscan 502 unit with CAP measurement. All patients had ammonia estimated from whole blood. At high ammonia, LOLA was ordered at 9 g/day for 8 weeks, with control of blood ammonia, AST, ALT, GGT, CRP and ferritin, as well as fibrosis and steatosis post-therapy.
Results. The study enrolled 45 patients of the MAFLD and 45 — of control cohort. Hyperammonaemia was revealed in 26 (58 %) MAFLD and 3 (7 %) control patients (p <0.001). MAFLD-hyperammonaemic patients also had the significantly higher male ratio, type 2 diabetes and severer hepatic steatosis rates vs. hyperammonaemia-negative MAFLD individuals. In 8 weeks of LOLA therapy, the ALT, AST, GGT, ferritin and CRP levels decreased significantly, and blood ammonia attained normal range (p <0.001). Elastometry liver stiffness decreased in 22 (85 %) patients, reaching F0 values in 6 cases (p <0.001). The steatosis grade reduced in 18 (69 %) individuals.
Conclusion. LOLA normalises blood ammonia levels and reduces the severity of inflammation, steatosis and liver fibrosis.
Background. The cholecystectomy is the major cause of sphincter of Oddi dysfunction (SOD), that may be classified as post-cholecystectomy syndrome (PCES). Treatment of PCES requires in most of the cases application of selective antispasmodic drugs.
Aim. To evaluate efficacy and safety of hymecromone in patients with post-cholecystectomy SOD, to compare standard and reduced doses of hymecromone.
Methods. Overall, 26 patients were enrolled in non-interventional comparative study: 2 males, 24 females, aged from 25 to 74 years. All patients underwent cholecystectomy for symptomatic gallstone disease within 1 to 10 years prior to beginning of the study. All patients were diagnosed to have SOD according to Rome IV Diagnostic Criteria for functional biliary sphincter of Oddi disorder (E1b). All patients underwent hymecromone monotherapy for 3 weeks. Patients were randomized to group A and B to receive full-dose or half-dose of the drug respectively.
Results. Abdominal pain completely subsided in 85 % of patients, significant improvement was found for bloating and diarrhea. Mild increase in fasting common bile duct (CBD) diameter after treatment (7.23 ± 0.99 vs 6.78 ± 1.01; p = 0.029) was attributed to choleretic action of hymecromone. Hymecromone resulted in significant improvement of CBD response to fatty meal stimulation (ΔCBD): –1.08 ± 0.46 mm vs –0.10 ± 0.33 mm pretreatment (p = 0.016). Degree of improvement was more pronounced in the group A (full-dose) as compared to group B (half-dose) for abdominal pain (Z = 2.74, p = 0.031), bloating (Z = 2.63, p = 0.035) and constipation (Z = 2.61, p = 0.038)
Conclusion. Hymecromone demonstrated itself to be an effective and safe drug, that may be applied both in standard and half dose. However, the efficacy of full-dose is higher both for the treatment of biliary pain and dyspeptic symptoms. Transabdominal ultrasound may be applied as a reliable test for both prediction of treatment efficacy and to monitor patients state during treatment course.
Aim. A definition and systematisation of sigmoid diverticulitis semiotics in a comprehensive ultrasonic check-up for early illness diagnosis.
Materials and methods. Ultrasound examination data on 64 patients with sigmoid diverticulum have been analysed. The primary visit reason was recurrent varying-intensity pain in left abdominal quadrant, unstable stool and flatulence. The patients were 28 (43.75%) men and 36 (56.25%) women aged 38–85 years, mean age 55.6 years; 31 (48.44%) were diagnosed with diverticulitis. We used the HD15 (Philips, the Netherlands), HS 60 (Samsung, South Korea) and Hi Vision Preirus (Hitachi, Japan) ultrasound instruments equipped with convex and intracavitary microconvex 2–12 MHz linear transducers. Patients were examined on an empty stomach and unprepared intestine. Colon and rectum were explored at different approaches, transabdominally, transperineally, transrectally and transvaginally
Results. The findings laid out a more elaborated ultrasound semiotics of diverticulitis. Ultrasound check-up enables a reliable estimation of blood supply and peristalsis, colonic wall thickness and layers, presence of asymptomatic diverticula, signs of acute diverticulitis (pain on sensor touch, mesocolic tissue infiltration, presence of faecal calculi and gas in diverticulum, peridiverticulitis) and other complications of diverticular disease (fistulae, abscess or peritonitis), as well as a consistent differential instrumental diagnosis of other organ illnesses.
Conclusion. Ultrasound is an indispensable supplement in clinical diagnosis of diverticula, diverticulitis and their complications in the cases when other methods like X-ray, CT or colonoscopy are contraindicated.

Aim. A comparative review of the rabeprazole properties vs. other PPIs, its efficacy and safety in treatment for aciddependent diseases.
Key points. Rabeprazole provides a rapid proton pump blockade in parietal cells due to its high dissociation constant (pKa). A lower rabeprazole metabolic dependence on cytochrome P-450 enzyme system renders its antisecretory effect predictable and reduces the risk of interactions with other drugs metabolised through this system. A faster antisecretory effect and higher acid-suppressive activity of rabeprazole determine its better clinical efficacy in treatment for such acid-dependent diseases as gastroesophageal reflux disease and peptic ulcer. This makes rabeprazole (Pariet) a preferred drug in course and maintenance therapies for acid-dependent diseases, as well as in H. pylori eradication.
Conclusion. The rabeprazole properties of high acid suppression potential, persistent antisecretory effect from first day of therapy, non-enzymatic metabolism and pleiotropic action determine its high efficacy in treatment for a wide range of acid-dependent diseases at a minimal risk of drug interaction.
CLINICAL CASES
Aim. A clinical observation of colitis conditioned by mycophenolate mofetil intake and concomitant Clostridium difficile-associated disease.
Key points. Mycophenolate mofetil (MMF) is an active immunosuppressant with side effects affecting gastrointestinal tract (GIT). A 37-yo male patient with type 1 diabetes mellitus was admitted at a gastroenterology unit with clinical signs of diarrhoea with haematochezia. A history of diabetic nephropathy and related-donor pre-dialysis kidney transplantation in 2012, since when MMF intake was 2000 mg daily. Catarrhal ulcerative colitis in colonoscopy, C. difficile toxins in pathogen stool panel. Ulcerative, ischaemic colitises and the graft-versus-host disease were ruled out in examination. A positive clinical and endoscopic trend was observed upon MMF withdrawn and start of vancomycin.
Conclusion. The case presented illustrates the clinical picture and diagnostic algorithm in MMF-associated colitis. The case-distinctive is association with C. difficile infection.
CLINICAL GUIDELINES
Aim. The clinical guidelines are intended to supplement specialty decision-making for improved aid quality in patients with gastritis and duodenitis though acknowledging the latest clinical evidence and principles of evidencebased medicine.
Key points. Gastritis is an inflammatory disease of stomach mucosa, with a separate definition of acute and chronic gastritis. Chronic gastritis is a cohort of chronic diseases uniting a typical morphology of persistent inflammatory infiltration, impaired cellular renewal with emergent intestinal metaplasia, atrophy and epithelial dysplasia of gastric mucosa. Oesophagogastroduodenoscopy (OGDS) or high-resolution OGDS with magnified or non-magnified virtual chromoendoscopy, including targeted biopsy for atrophy and intestinal metaplasia grading and neoplasia detection, are recommended to verify gastritis and duodenitis, precancer states and/or gastric mucosal changes. All chronic gastritis patients positive for H. рylori should undergo eradication therapy as aetiological and subsidiary for gastric cancer prevention. Chronic gastritis patients with symptoms of dyspepsia (epigastric pain, burning and congestion, early satiety), also combined with functional dyspepsia, are recommended proton pump inhibitors, prokinetics, rebamipide and bismuth tripotassium dicitrate in symptomatic treatment. With focal restricted intestinal metaplasia, follow-up is not required in most cases, mainly when advanced atrophic gastritis is ruled out in high-quality endoscopy with biopsy. However, a familial history of gastric cancer, incomplete intestinal metaplasia and persistent H. pylori infection render endoscopy monitoring with chromoendoscopy and targeted biopsy desirable once in three years. Patients with advanced atrophic gastritis should have high-quality endoscopy every 3 years, and once in 1–2 years if complicated with a familial history of gastric cancer.
Conclusion. The recommendations condense current knowledge on the aetiology and pathogenesis of gastritis and duodenitis, as well as laboratory and instrumental diagnostic techniques, main approaches to aetiological H. pylori eradication and treatment of dyspeptic states.
