Chronic Pain Following Thermal Burn Injury Clinical Trial
Official title:
Pilot, Double-blind, Randomized Controlled, Multi-center Study of the Effects of Fish Oil and Vitamin D in the Prevention of Chronic Pain Following Major Thermal Burn Injury
The goal of this study is to develop a safe, effective, and readily available treatment that will prevent chronic pain following Major Thermal Burn Injury (MThBI). Burn survivors are prone to develop chronic pain and there is an urgent unmet need for preventative treatments. The preventative treatments proposed for this study, Omega-3 Fatty Acids (O3FA) and Vitamin D have been selected given effectiveness across a range of painful musculoskeletal disorders and their wide availability and low cost. This study is a 2x2 factorial, double-blind, placebo-controlled randomized controlled trial test for the effectiveness of O3FA and Vitamin D to prevent chronic pain development. Burn survivors will be enrolled who have experienced thermal burns that cover less than 30% total body surface area that are severe enough to warrant surgical management, which represents the most common burn injury characteristics. Patients will be enrolled within 72 hours of their burn, and randomized via 1:1:1:1 allocation to receive placebo, O3FA, Vitamin D or both. The investigators will obtain blood samples on enrollment and at 6 weeks to assist in elucidating key mechanisms by which O3FA and Vitamin D reduce chronic pain following MThBI. Chronic pain severity, assessed with a 0-10 numeric rating scale at 6 weeks, 3 months, 6 months and 1 year will be entered into a repeated-measures model. Model estimated contrasts will serve as the primary outcome.
Patients will be screened daily. Patients who meet eligibility criteria will be approached for participation. Patients interested in participating will proceed through informed consent. Once informed consent is obtained, an initial questionnaire will be administered, a blood draw will be performed to assess for baseline Vitamin D/O3FA concentration and immune profile. Then patients will be randomized into one of 4 treatment arms in 1:1:1:1 allocation. Patients will receive study drug for 6 weeks following burn injury. Adverse event monitoring will occur daily while inpatient and weekly once discharged from the hospital through 6 weeks. Patient compliance with the study drug will be assessed via patient-reported reported missing doses, pill counts at the end of the study, and a 6-week blood draw in which Vitamin D/O3FA levels and immune profile will be assessed. Patient-reported outcomes will be collected via follow-up survey at 6 weeks, 3 months, 6 months, and 1 year following burn injury.s, and 1 year following burn injury. ;
