Objectives:
With reports of high rates of sleep disruption in Human Immunodeficiency Virus (HIV) + persons, this study tested whether there were differences in sleep quality and well-being between a group of HIV+ persons who reduced their caffeine intake from baseline by 90% or greater for 30 days (n=44) versus a group of HIV+ persons who continued their usual caffeine consumption (n=44).
Methods:
Subjects were administered pre- and post-Pittsburgh Sleep Quality Index (PSQI), Perceived Well-being Scale-Revised (PWB-R) and MOS-HIV Health Survey instruments, with MOS-HIV summary scores used as a covariate.
Results:
On ANCOVA analysis for sleep quality (F=14.032, P<.001), a 35% improvement in sleep among experimental subjects was identified. There was no significant difference between the two groups on ANCOVA analysis for well-being (F=0.111. P=.739).
Conclusions:
High levels of caffeine consumption may have an exacerbating effect on already prevalent HIV-related sleep pattern disturbances, and significant reductions of caffeine may improve sleep quality.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
