Effect of Laparoscopic Sleeve Gastrectomy in the Morbidly Obese, Kidney Transplant Candidate
Study Details
Study Description
Brief Summary
A prospective clinical trial will study the effects of laparoscopic sleeve gastrectomy in the potential renal transplant candidate who is denied acceptance due mainly to the morbid obesity.
Condition or Disease | Intervention/Treatment | Phase |
---|---|---|
|
Detailed Description
The remaining factor in determining the effectiveness of bariatric surgery in the transplant population will be to study the effect on the pharmacokinetics of immunosuppressive medication, height, weight, BMI, abdominal circumference, blood pressure, Hba1c , average daily insulin requirements, lipid profile, TSH, 24h urine creatinine clearance and the SF-36 Quality of life questionnaire.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
morbidly obese, chronic renal disease adult patients (> 18 years) who have stage 4 or 5 chronic renal disease (CrCl < 30 ml/min) who are being considered for possible future kidney transplantation. The study inclusion criteria are an indication for laparoscopic sleeve gastrectomy (BMI > 40 kg/m2, or BMI > 35 with at least one co-morbidity such as hypertension, dyslipidemia or diabetes) |
Procedure: laparoscopic sleeve gastrectomy

Outcome Measures
Primary Outcome Measures
- changes in the pharmacokinetics of oral immunosuppressive medications due to bariatric surgery, comparing pre-bariatric surgery to 12 months post-operative [pre-bariatric surgery and 1 year after surgery]
Tacrolimus and Mycophenolate AUC 0-24h
- degree of weight loss achieved after bariatric surgery in the chronic renal failure patient. [baseline and every 3 months]
weight, BMI and abdominal circumference measures
- Evaluate the change in general quality of life score, SF-36 [Baseline and 1 year after bariatric surgery]
comparison of the SF score between Baseline and month 3, Baseline and month 6 and Baseline and month 12
Secondary Outcome Measures
- evaluate changes to residual renal function in the pre-dialysis renal transplant candidate [at baseline versus month 12 post-bariatric surgery]
serum creatinine/ urea, sodium, potassium, magnesium, calcium, phosphate and bicarbonate pre surgery and month 12
- evaluate the change in the number and dose of medications required to treat co-morbidities including, hypertension, hyperlipidemia and diabetes mellitus [baseline and 12 month post-bariatric surgery]
concommitant medication records at baseline vs month 12
- the incidence of complications post-bariatric surgery will be evaluated [1, 6 and 12 months post-bariatric surgery]
non serious and serious adverse events collection at Baseline, month 6 and month 12
