What this trial studies

This is a single-site, randomized, parallel-group trial at the University of Pennsylvania enrolling 60 hemodialysis patients randomized 1:1 to bright light or dim light delivered via special glasses during dialysis sessions. Participants will use the glasses for one hour during each dialysis session over four weeks. The primary outcome is change in fatigue severity, with secondary outcomes including salivary cortisol, insomnia, depression, quality of life, and physical activity. The trial compares bright light to a dim-light control to isolate the effect of light intensity on these measures.

Who should consider this trial

Good fit: Adults (≥18) with end-stage kidney disease on hemodialysis three times weekly for at least one month who report significant fatigue (Fatigue Severity Scale > 9) and can store saliva samples at home are ideal candidates.

Not a fit: Patients with eye disorders (e.g., cataracts, glaucoma, retinal disease), photosensitivity, those who are hospitalized or acutely ill, or those without clinically significant fatigue are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, this could provide a simple, non-drug way to reduce fatigue for patients receiving hemodialysis.

How similar studies have performed: Bright light therapy has shown benefits for fatigue, sleep, and mood in other chronic conditions, but evidence specifically in hemodialysis patients is limited.
