Effects of Salsalate on Prandial-Induced Vascular Inflammation After Spinal Cord Injury (SCI)

8. juni 2015 oppdatert av: Mark S. Nash, Ph.D., FACSM, University of Miami

Effects of Salsalate on Prandial-Induced Vascular Inflammation After SCI

The overall study objectives are to examine whether:

  1. 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
  2. An inexpensive, low-risk, widely-available pharmacotherapy safely reduces CVD risks associated with fasting and postprandial lipidemia, glycemia, and vascular inflammation.

Detaljert 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.
