Psychoemotional Status and Functional Gastrointestinal Disorders

Detailed Description Functional gastrointestinal disorders are highly prevalent and are currently understood within a biopsychosocial model that includes disturbances in gut-brain interaction. Functional dyspepsia and irritable bowel syndrome are frequently associated with anxiety, depression, and somatization, which may worsen symptom severity and reduce quality of life. This study is designed to evaluate the influence of psychoemotional disturbances on the clinical course of these disorders. This is a prospective cohort study planned for 2 years and will enroll 150 adult patients with functional dyspepsia and/or irritable bowel syndrome. Eligible participants must be 18 years of age or older, meet Rome IV diagnostic criteria, and provide informed consent. Patients younger than 18 years, those who do not meet Rome IV criteria, and those with inflammatory bowel disease, pregnancy or lactation, malignant neoplasms, or a history of gastrointestinal surgery will not be included. Participants may be withdrawn if they choose to discontinue participation at any stage. At the baseline visit, after informed consent is obtained, an individual case report form will be completed. Patients will undergo assessment of quality of life using SF-36, psychoemotional status using PHQ-9, GAD-7, and PHQ-15, and pain severity using a visual analogue scale. Patients with irritable bowel syndrome will also complete an assessment of stool form and stool frequency using the Bristol stool scale. In patients with functional dyspepsia, Helicobacter pylori status will be assessed using available laboratory or diagnostic methods, including 13C urea breath test, stool PCR analysis, rapid urease test, or esophagogastroduodenoscopy with biopsy. At the second visit, participants will repeat the questionnaires to assess changes after treatment, and the investigator will evaluate clinical status and adjust treatment if necessary. The primary outcome measure is quality of life as assessed by SF-36. Secondary outcome measures include changes in PHQ-9, GAD-7, and PHQ-15 scores over time. The study will also explore the relationship between Helicobacter pylori status and psychoemotional status and quality of life in patients with functional dyspepsia.
