DT 9602 AU Ferini-Strambi L; Oldani A; Tirloni G; Zucconi M; Castagna A; Lazzarin A; Smirne S; Sleep Disorders Center, State University, Milan, Italy. SO Sleep. 1995 Jul;18(6):446-50. Unique Identifier : AIDSLINE MED/96066127 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.
