Metabolic Parameters 3 Months, 9 Months, and 2 Years After Bariatric Surgery

- Procedure: Bariatric surgery
- Registration Number
- NCT00178633
- Brief Summary
An original cohort of 43 patients were recruited for analysis of anthropometrics, metabolic profile, skeletal muscle biopsy, echocardiogram at baseline, 3 months and 9 months post bariatric surgery. While all 43 patients reportedly completed 3 and 9 month evaluations, only 15 patients completed 24 month evaluations due to 28 patients unwilling to return.
The overarching purpose appears to have been not only evaluation of weightloss, but normalization of metabolic profile over time.

- The subjects in this study will represent both male and female patients with clinically severe obesity (BMI > 40kg/m2 or 35kg/m2 with significant obesity related co-morbidities), who have chosen to undergo elective bariatric surgery. Patients are screened through the University of Texas Houston Bariatric Surgery Center (UTHBSC) and are evaluated for bariatric surgery, defined in this study as small pouch gastric bypass with Roux-en-Y (SPGB), or laparoscopic adjustable gastric banding (LAGB). Adults (>18)from diverse ethnic backgrounds, with clinically severe obesity, are eligible to be evaluated for bariatric weight loss surgery in the UTHBSC. Candidates considered for the study are patients who not only fulfill the criteria for weight loss surgery, but also demonstrate a high likelihood of complying with the long-term follow-up that is required for a successful study.
Patients who have components of the metabolic syndrome (hypertension, diabetes, and dyslipidemia) will be included if these complications do not preclude a safe operation. .
Exclusion criteria include age over 70 years, current history of smoking, coronary artery disease, congestive heart failure, ischemic cardiomyopathy, known peripheral vascular disease, severe psychiatric disease, any medical problem or physical contraindication for surgery (as determined by the physician) and pregnancy. This study will be limited to adults since the safety of gastric bypass surgery has not been shown to be safe in children in large clinical trials

- Arm && Interventions
Group Intervention Description Bariatric Surgery Bariatric surgery Procedures were not part of the trial. Patients already undergoing these clinical procedures agreed to analysis and follow-up for research purposes. All patients had one of two different types of procedures, but outcome analyses did not distinguish between the two procedures.
- Primary Outcome Measures
Name Time Method Change in Weight 0 to 9 months Change in weight. Negative values represent weight loss.
- Secondary Outcome Measures
Name Time Method Change in Glucose 0-9 Months Change in glucose. Negative values represent a decrease in glucose levels.
Change in Left Ventricular Mass 0-9 Months Change in left ventricular mass, or myocardium, as measured in centimeters using echocardiography. Negative values represent a decrease in ventricular mass.
Change in Tissue Doppler Diastolic Velocity 0-9 Months Change in tissue doppler diastolic velocity. Negative values indicate a decrease in tissue doppler diastolic velocity.
