Systematic Light Exposure Effects on Circadian Rhythms Entrainment, Inflammation, Neutropenic Fever and Symptom Burden Among Multiple Myeloma Patients Undergoing Autologous Stem Cell Transplantation
Icahn School of Medicine at Mount Sinai
Summary
The aim of this multi-site randomized control trial will be is to assess the impact Systematic lighting on circadian rhythm entrainment, Inflammation, Neutropenic Fever and Symptom Burden among Multiple Myeloma Patients undergoing Autologous Stem Cell Transplantation. To achieve this aim, 200 multiple myeloma patients will receive one of two different light-treatments that are designed to promote circadian rhythm alignment. While receiving these light treatments, participants' sleep efficiency, urine melatonin levels, blood inflammatory cytokine levels and symptoms will be assessed over a 2-month period.
Description
Individuals undergoing Autologous Stem Cell Transplant (ASCT) experience major transplant-related complications including elevated symptom burden, high rates of neutropenic fever, and increases in inflammatory cytokines. These transplant-related complications are augmented by circadian rhythms disruption (CRD), which leads to misalignment between melatonin levels and sleep times. Since light is a strong synchronizer of circadian rhythms, the proposed multi-site randomized controlled trial (RCT) will investigate whether lighting designed to deliver circadian effective light that promotes circad…

Interventions
- DeviceCircadian Effective Lighting
Participants will receive lighting with a spectrum of 300K, 500 lux to the eye level between 7:00am and 10:00am in the morning, and hospital lighting (\<100lux) during the afternoon between 10:00am and 6:00pm. In the evening this group of participants will receive lighting with a spectrum of 3000K, \<50lux at eye light level between 6:00PM and bedtime.
- DeviceCircadian Ineffective Lightning (CIL)
Participants will receive lower lighting levels in the morning (lighting with A spectrum of 300k, \<50lux to the eye level between 7:00am and 10:00am) and the same lighting levels throughout the rest of the day.
