Background: Bariatric surgery is the most effective long-term treatment for morbid obesity, reducing obesity-associated co-morbidities. We decide to investigate the role of the polymorphism (G1359A) of the cannabinoid (CB)1 receptor gene on clinical outcomes 1 year after biliopancreatic diversion in morbidly obese patients.
Design: A sample of 66 morbidly obese patients (BMI >40 kg/m2) were operated. Weight, fat mass, blood pressure, basal glucose, triacylglycerols, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol were measured at basal visit and at each visit. The frequency of metabolic comorbidities was recorded at each visit.
Results: Thirty-nine patients (59.1%) had genotype G1359G (wild type group) and 27 (40.9%) patients had genotype G1359A (mutant type group). In wild and mutant type groups, body mass index, weight, waist circumference, systolic blood pressure, glucose, total cholesterol, low-density lipoprotein cholesterol and triacylglycerols concentrations decreased, without statistical between genotype groups. Initial weight percent loss at 1 year of follow up was similar in both genotypes (33.1% vs 33.6%; ns).
Conclusion: The present study demonstrates that polymorphism G1359A in the CB1 receptor did not have a significant effect on biochemical and anthropometric improvements after biliopancreatic diversion surgery.
