Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Our primary objective is to compare pre-treatment with the standard low calorie diet with pre-treatment with supplemental omega-3 fatty acids on liver volume. ;Secondary Objective: Secondary objectives are patient satisfaction about different dietary pre-treatments, the effect of omega-3 fatty acids before and after bariatric surgery on immune function, including adipose tissue macrophage function, cortisol response, erythrocyte function, and the long term effect of bariatric surgery on immune function and erythrocyte function six months after surgery.;Primary end point(s): Volume of the left hepatic lobe;Timepoint(s) of evaluation of this end point: 4 weeks | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • The ex-vivo inflammatory cytokine response in LPS stimulated whole blood cells before and after bariatric surgery, measured as: o TNF-alpha o IL-6 o IL-10 • The low-grade inflammatory state of adipose tissue, measured by the infiltration of macrophages, expression of Netrin-1 and Unc5b, different adopokines, cytokines, signal transduction molecules and 11ß-HSD-1 in adipose tissue biopsies • Erythrocyte deformability, measured as elongation index (EI) by the LORRCA • Erythrocyte aggregation, measured as aggregation index (AI) by the LORRCA • Cortisol response, measured with ACTH-stimulation test • Serum levels of cytokines before and after bariatric surgery, measured as: o TNF-alpha o IL-6 o IL-10 • Serum levels of C-reactive protein, HDL-cholesterol, LDL-cholesterol, triglycerides and fasting glucose • Weight, height and BMI • Postoperative outcome;Timepoint(s) of evaluation of this end point: 4 weeks, first postoperative day and after 6 months | — |
