Effects of Salsalate on Prandial-Induced Vascular Inflammation After Spinal Cord Injury (SCI)
Effects of Salsalate on Prandial-Induced Vascular Inflammation After SCI
The overall study objectives are to examine whether:
- Persons with spinal cord injury (SCI) having elevated body mass are at greater cardiovascular disease (CVD) risk for fasting and postprandial lipidemia, glycemia, and vascular inflammation than persons with SCI having 'normal' body mass, and
- An inexpensive, low-risk, widely-available pharmacotherapy safely reduces CVD risks associated with fasting and postprandial lipidemia, glycemia, and vascular inflammation.

Detaljeret beskrivelse
To test Study Objective 1, 'overweight' and 'non-overweight' persons with SCI will be compared at baseline for fasting and postprandial responses. For Study Objective 2, all persons tested for Study Objective 1 will undergo randomization to either 1 month of Salsalate (4.0 g/day) or placebo. An untreated wash-in (1 month) will precede treatment (1 month), and a washout cross-over period (1 month) will follow. The last month will test effects of drug-placebo not examined in month 2. Fasting and postprandial responses will be tested at each time point. Intention-to-treat clinical standards ("…as randomized, so analyzed…") and 'last observation carried forward' clinical methods will be adopted.
Participants with tetraplegia are sought, as they have fewer exercise options than those with paraplegia and are at greater risk for sedentary lifestyle resulting in CVD, CVD risks, and obesity.

The postprandial lipemia is assessed by the change in the AUC for plasma triglycerides sampled before and after intervention at time points 0 (immediately post-feeding)to 480 min. For peak TG, and TG area under the curve (AUC), treatments (placebo and salsalate) and visits (pre and post treatment) were defined as within-subject's factors. |
