Abstract | INTRODUCTION: METHODS: This retrospective analysis of the PRO-ACT database addresses the impact of melatonin on progression and overall survival of ALS. A Cox proportional hazards ratio model was performed to investigate the effect that melatonin had on time to death. For secondary outcome measures, linear mixed effects regression models were used to ascertain the effect of melatonin on change in standardized ALS Functional Rating Scale (sALSFRS) and percentage predicted forced vital capacity (FVC) scores. RESULTS:
Melatonin users had a significantly decreased annualized hazard death rate compared with the non- melatonin users (hazard ratio, 0.241; 95% confidence interval, 0.088-0.659; P = .0056). The melatonin users also had a slower rate of decline in sALSFRS score (t = 2.71; P = .0069) and change in percent predicted FVC score (t = 2.94; P = .0035) compared with the non- melatonin users. DISCUSSION: Our findings suggest that melatonin may be beneficial for patients with ALS. Due to the nature of this database, our results are solely intended to be hypothesis-generating and no strong associations can be made. Given the low cost and favorable safety profile of melatonin, the hypotheses generated warrant further investigation.
