The role of nitric oxide in the development of gastroesophageal reflux disease against the backdrop of obesity
Today gastroesophageal reflux disease (GERD) occupies a leading position among chronic diseases of the gastrointestinal tract. The prevalence of GERD in people with normal BMI ranges from 15 to 20%, with obesity – from 50% to 100%. The basis of GERD is a violation of the motor – evacuation function of the gastroesophageal zone, which is accompanied by a steady relaxation of the antireflux barrier. Nitric oxide (NO) plays an important role in this process. The aim of this work is to study the level of nitric oxide in patients with gastroesophageal reflux disease on the background of obesity and to assess its impact on the course of the disease. Materials and methods. The study involved 80 young people. Questionnaire was conducted using the GERDQ questionnaire, BMI, serum nitric oxide level by Griss spectrophotometric method with sulfanilic acid and 1-naphthylamine, FGDS to determine the severity of reflux esophagitis. Study participants were divided into 3 groups: patients with GERD with concomitant obesity, patients with GERD without concomitant pathology, the control group, which consisted of almost healthy individuals. Analyzing the obtained results, a significant increase in the concentration of nitric oxide in the blood of patients with GERD with concomitant obesity, compared with patients with GERD without concomitant pathology and the control group. There is a direct correlation between the level of nitric oxide in the blood and the severity of reflux esophagitis in patients with GERD with concomitant obesity. Further study of the role of nitric oxide in the pathogenesis of comorbid GERD and obesity will contribute to the development of improved methods for diagnosis, treatment and prediction of disorders.
