Identification of Biomarkers of Response After Bariatric Surgery in Morbidly Obese Patients — PREDI-BAR  

Morbid Obesity Clinical Trial

Official title:
Identification of Biomarkers of Response After Bariatric Surgery in Morbidly Obese Patients

Clinical Trial Summary

The prevalence of obesity in Spain is about 21.6%. The discouraging results provided by dietary treatment, together with the lack of funding for pharmacological treatment, have led to the progressive use of bariatric surgery (CB). Besides weight loss, CB associates a beneficial effect on metabolic comorbidities. However, 25-30% of operated patients present a weight response considered inappropriate, they do not resolve their comorbidities and/or present a weight-regain shortly after surgery. Therefore, predictive strategies are necessary to allow a correct selection of obese patients who are candidates for CB. The main hypothesis of the study is that various factors such as psychopathological profile, body composition and metabolic alterations related to morbid obesity can influence the response to bariatric surgery.

Clinical Trial Description

The investigators have designed a prospective study in which 200 consecutive patients from the outpatient clinic of the Morbidly Obesity Unit of the Vall d'Hebron Hospital will be included, meeting criteria for bariatric surgery (with BMI> 40 kg / m2 or BMI> 35 kg /m2 in the presence of comorbidities) and will undergo surgery in the investigator's center between September 2018 and September 2019. All patients will undergo (baseline, month, 6, 12 and 24 month): complete clinical history, analysis complete biochemistry, 2 blood samples will be extracted to study metabolomics, stool sample for microbiota study, bioimpedance for the study of body composition, determination of AGEs in the skin and lens, cognitive function assessment, retinal function assessment by microperimetry and they will be asked to complete several specific questionnaires for the evaluation of the psychopathological profile and the dietetic survey. ;
