What is the purpose of this trial?

This trial explores whether vitamin D can help prevent chronic pain in people who have experienced burn injuries. Researchers aim to determine the safety of a one-time dose of vitamin D and its effects on the immune system post-burn. Participants will receive either vitamin D (Ergocalciferol) or a placebo (a harmless pill with no active ingredients) and will report their pain levels while providing blood samples for analysis. The trial seeks individuals admitted to a hospital for a burn injury who have a smartphone and experience severe pain. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group, offering a chance to contribute to important findings.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, if you are taking Vitamin D supplements in excess of 800 IU daily, you may not be eligible to participate.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that Vitamin D2, also known as ergocalciferol, is generally safe for people. It often helps maintain healthy bones and muscles. Studies have found that Vitamin D can also aid in healing and boosting the immune system for burn patients.

In this trial, researchers will closely monitor the safety of Vitamin D2 for people with burn injuries. Participants will report any side effects they experience over six weeks. This will help researchers determine if Vitamin D2 is well-tolerated in this specific situation.

In summary, Vitamin D2 is considered safe based on past use, but this study will provide more detailed information about its safety after burn injuries. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for chronic pain after burns, which often include opioids and non-steroidal anti-inflammatory drugs (NSAIDs), Ergocalciferol, a form of Vitamin D2, is being explored for its potential pain-relieving properties. Researchers are excited about Ergocalciferol because it represents a non-opioid alternative, which could reduce the risk of addiction and side effects common with current pain medications. Additionally, Vitamin D2 might work by modulating inflammation and supporting nerve health, offering a novel mechanism that could complement existing pain management strategies.

What evidence suggests that Vitamin D might be an effective treatment for chronic pain after burns?

This trial will compare Vitamin D2 (Ergocalciferol) with a placebo to assess its effects on chronic pain after burns. Research has shown that low Vitamin D levels are linked to worse chronic pain, and taking Vitamin D supplements might improve pain, sleep, and quality of life for burn patients. Studies have found that burn patients often have low Vitamin D, which can lead to issues like muscle weakness and itching. Taking Vitamin D, such as Ergocalciferol, might aid in muscle recovery and strength after burns. While more data is needed on pain relief specifically from Vitamin D, these findings suggest it could help manage chronic pain after burns. ^{1 2 3 6 7}

Published Research Related to This Trial

A systematic review of 81 observational studies involving over 50,000 participants found that patients with arthritis, muscle pain, and chronic widespread pain had significantly lower levels of 25-hydroxyvitamin D (25(OH)D) compared to controls, indicating a potential link between low vitamin D levels and these pain conditions.

The study also revealed that the odds of vitamin D deficiency were higher in individuals with arthritis, muscle pain, and chronic widespread pain, suggesting that monitoring and addressing vitamin D levels could be important in managing these conditions.

Is there role for vitamin D in the treatment of chronic pain? Martin, KR., Reid, DM.[2023]

Five patients experienced unusual hyperesthetic pain linked to low vitamin D levels, which resolved within 5 to 7 days after receiving vitamin D supplementation (ergocalciferol).

The pain did not respond to typical analgesics or tricyclic antidepressants, suggesting a specific pain syndrome related to vitamin D deficiency that can significantly impact mobility and function.
