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.

Outcome Measures

Primary Outcomes (1)

  • Change in Weight

    Change in weight. Negative values represent weight loss.

    0 to 9 months

Secondary Outcomes (3)

  • Change in Glucose

    0-9 Months

  • Change in Tissue Doppler Diastolic Velocity

    0-9 Months

  • Change in Left Ventricular Mass

    0-9 Months

Study Arms (1)

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.

Procedure: Bariatric surgery

Interventions

Bariatric surgery was not part of this trial. This was observational trial of persons post-bariatric surger.

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Male and female, adult patients with clinically severe obesity who have undergone elective bariatric surgery.

You may qualify if:

  • 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. .
