Modern aspects of the pathogenesis and treatment of dyspepsia

A review of current data suggests that the attention to the problem of dyspepsia is huge. The definition of functional dyspepsia was given in the Rome IV criteria, according to which two of its main options are distinguished – epigastric pain syndrome and postprandial distress syndrome. The term “uninvestigated dyspepsia” is important, which means the presence of dyspepsia symptoms in patients who have not performed diagnostic procedures to identify the organic causes of the pathology. The prevalence of uninvestigated dyspepsia in the world is about 21%. The prevalence of functional dyspepsia is significantly lower than the prevalence of uninvestigated dyspepsia and fluctuates around 10%. The risk factors for dyspepsia are usually tobacco smoking, non-steroidal anti-inflammatory drugs and/or aspirin, and Helicobacter pylori infection. The concept of the pathogenesis of functional dyspepsia undergoes significant changes. By analogy with the pathophysiology of irritable bowel syndrome, lesions of the relationship between the modulation of the cerebral cortex and the signal system of the gastroduodenal zone, the association of sluggish immune inflammation in the duodenum with motility and sensory activity of the stomach are most actively studied. The treatment of functional dyspepsia is a complex problem and changes after new ideas about its pathogenesis. Modern meta-analyzes have made it possible to expand the indications for the proton pump inhibitors administration, which can be actively used not only for the treatment of epigastric pain syndrome, but also for postprandial distress syndrome. Along with the required Helicobacter pylori eradication, there are reasons for the use of probiotics and antibiotics for the dyspepsia treatment.
