Abstract:
PURPOSE:Corticosteroids, which are a mainstay in the treatment of acute lymphoblastic leukemia (ALL), have a well-documented adverse effect on sleep. We sought to characterize the effects of dexamethasone on sleep over an entire 28-day treatment cycle using actigraphy, an objective measure of sleep. METHODS:The sleep of 25 children aged 2-9 years (mean 4.5 years) with ALL treated with dexamethasone were evaluated during maintenance chemotherapy using a within-subject experimental design, actigraphy, and standardized questionnaires to assess sleep, sleep problems, and fatigue. RESULTS:During the five days of dexamethasone treatment, sleep time increased during the night (535 vs. 498 min; p = 0.004) and daytime napping increased the following day (14 vs. 0 min; p = 0.002), and the number of wake episodes during the night was lower (14 vs. 20; p = ≤ 0.001). However, when assessed individually, sleep-onset time, efficiency, and wake after sleep onset during the night were unchanged during dexamethasone treatment; when the cumulative effect of all of these factors was assessed, there was a statistically and clinically significant increase in nighttime sleep duration during dexamethasone treatment. CONCLUSIONS:During the five days of treatment with dexamethasone, an increase in nighttime sleep as well as daytime napping was observed in young children with ALL. The increases in sleep duration return to baseline one day after the discontinuation of dexamethasone.
