AB Alterations of sleep structure have been reported in asymptomatic human
immunodeficiency virus (HIV)-infected subjects. In these patients some
authors have found an increased percentage of slow wave sleep (SWS) and
a SWS preponderance in the second half of the night, as well as
subjective sleep complaints. Other authors have found an increased stage
1 non-rapid eye movement (NREM) and reduced stage 2 NREM percentages in
asymptomatic subjects. We evaluated the macrostructure and the
microstructure (cyclic alternating pattern, CAP) of sleep in nine
HIV-infected asymptomatic men without sleep complaints or psychiatric
illness, in comparison with nine age-matched controls. Our study showed
a decreased amount of SWS and a significantly higher CAP rate in
HIV-subjects, suggesting an altered organization of the sleep process in
these patients.
