Summary
Brief summary
Myalgic encephalomyelitis, or chronic fatigue syndrome (ME/CFS) is a severe, chronic disease with an estimated prevalence of 0.76% in the Australian population. Post-exertional malaise (PEM) is the key symptom of ME/CFS which can last for several weeks or months, where patients have an exacerbation of symptoms (chronic fatigue, headaches, sleep disturbance, brain fog etc) following exertion, that cannot be relieved by sleep or rest. Simple everyday activities (such as walking and showers) can trigger PEM. Patients may face years of persistent symptoms including fatigue, PEM, sleep disturbance, impaired cognition, mood disturbance and muscle and/or joint pain. Despite the debilitating nature of its symptoms and high personal and socio-economic burden, there is no clear understanding of the underlying pathophysiology of the disease and no effective treatments .
ME/CFS is a complex multisystem disease with potential involvement of the immune system, nervous system, and the musculoskeletal system in addition to nociception, mitochondria metabolism, and oxidative defence mechanisms. To be efficacious, potential treatments will need to target multiple systems and multiple processes to meaningfully impact quality of life. We believe that krill oil is a potential treatment option.
Krill oil is a sustainable source of the long chain omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). It is also high in the antioxidant astaxanthin and the essential nutrient choline. EPA and DHA play critical roles in brain and metabolic function, in addition to being potent anti-inflammatory agents with analgesic properties. It is also known to improve cognitive and sleep quality. Choline plays an important role in the nervous system and energy metabolism while astaxanthin is a potent antioxidant proven to improve oxidative stress in humans. These compounds have systemic biological actions, and they have the potential to alleviate some of the systemic disruptions associated with ME/CFS such as brain fog, chronic pain and sleep disturbance resulting in reduced fatigue. Therefore, we propose that krill oil may be a viable treatment option for ME/CFS.

Will individual participant data (IPD) for this trial be available (including data dictionaries)?
Yes
What data in particular will be shared?
All data collected during trial, analysed, and stored in re-identifiable format so that we can provide individual feedback to participants on their responses to intervention. Results will be made available to participants if requested. The Principal Researchers will communicate these results to the participants or provide participants with a printed non-identifiable output of their results.
When will data be available (start and end dates)?
Start dates: December 2024, no end date.
Available to whom?
Participants
Available for what types of analyses?
Individual feedback to participants on their responses to intervention.
How or where can data be obtained?
Individual results will be available to the participants via email at the participant’s request. They will have the opportunity to contact the Principal Researcher by emailing (Lee.Hamilton@deakin.edu.au) to discuss their data in more detail if they would like.
