Abstract
INTRODUCTION: Obese patients often find it difficult to adhere to long-term low-calorie diets. One of the reasons for dietary failure is the permanent feeling of hunger. Ghrelin is an orexigenic hormone, secreted by enterochromaffin cells in the gastric fundus. The aim of this study was to analyze changes in plasma ghrelin levels after PENS of dermatome T6 associated to a low-calorie diet, as well as changes in appetite and weight loss, as compared to a control group on a low-calorie alone. MATERIAL AND METHODS: A prospective, non-randomized study was conducted including 20 patients who underwent PENS of dermatome T6 associated to a low-calorie diet before undergoing bariatric surgery to lose weight (Group 1), and 20 patients who were only prescribed a low-calorie diet before surgery (Group 2). In Group 1, plasma ghrelin levels were measured at 5 timepoints: before the first PENS session (Sample 1a); after the first PENS session (Sample 1b); before the last PENS session (Sample 2a); after the last PENS session (Sample 2b); and one month after treatment completion (Sample 3). In Group 2, only two samples were collected: before the start of the diet (Sample 1) and after 12 weeks of diet (Sample 2). RESULTS: After 12 weeks of treatment, BMI decreases of 8.42%±2.6% and 1.32%±0.98% were seen in Group 1 and Group 2 respectively (p=0.007). A significant decrease was seen in ghrelin levels between samples 1a and 2a, and between samples 1a and 3. In Group 2, a non-significant increase was seen in ghrelin levels. CONCLUSION: PENS of dermatome T6 was associated to decreased plasma ghrelin levels. This therapy, associated to a low-calorie diet, achieves a BMI reduction greater than 8% after 12 weeks of treatment.
