Increased risk of chronic fatigue syndrome following burn injuries.
Tsai, Shin-Yi, Lin, Cheng-Li, Shih, Shou-Chuan et al. · Journal of translational medicine · 2018 · DOI
Quick Summary
This study found that people who suffer burn injuries have a higher chance of developing ME/CFS later on. Researchers looked at over 17,000 people in Taiwan who had burn injuries and compared them to a similar group without burns. Those with burns were about 1.5 times more likely to develop ME/CFS, and burns in visible areas like the face and arms had a stronger link to ME/CFS than burns on the trunk.
Why It Matters
This study strengthens the evidence that ME/CFS can develop following acute systemic insults, supporting post-viral and post-injury pathophysiology hypotheses. Understanding risk factors for ME/CFS development following identifiable triggers like burn injury may help clinicians identify high-risk patients for early intervention and monitoring.
Observed Findings
Burn injury patients had an incidence of 1.61 CFS cases per 1000 person-years compared to 0.86 in matched controls.
Adjusted hazard ratio for CFS following burn injury was 1.48 (95% CI 1.41-1.56).
Increased CFS risk persisted across all strata (sex, age, and comorbidity subgroups).
Burn injuries to sun-exposed areas (face, limbs) showed greater association with subsequent CFS than trunk injuries.
Extensive burned areas and visible scars were associated with greater physiological and psychosocial burden.
Inferred Conclusions
Thermal injury is an independent risk factor for subsequent ME/CFS development.
Location and extent of burn injury may influence the likelihood of ME/CFS development.
Burn patients with extensive scarring and visible disfigurement warrant long-term follow-up monitoring for ME/CFS symptoms.
Remaining Questions
What are the biological mechanisms linking acute burn injury to ME/CFS pathophysiology?
Does the timing of ME/CFS onset following burn injury vary, and if so, what factors predict earlier versus delayed onset?
What This Study Does Not Prove
This study cannot establish causation or explain the biological mechanisms linking burn injury to ME/CFS—it only shows an association. The findings cannot determine whether burn-related stress, inflammation, infection, or other factors directly trigger ME/CFS, nor can they explain why some burn patients develop ME/CFS while others do not. Administrative database coding may not capture clinically confirmed ME/CFS cases with strict diagnostic criteria.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
