Nefazodone and REM sleep: how do antidepressant drugs decrease REM sleep?

In previous uncontrolled studies, nefazodone, a new antidepressant drug, increased REM sleep or had no effect on REM sleep. We report a double-blind, placebo-controlled, parallel group study on effects of nefazodone (N) on polysomnographic sleep variables in healthy human volunteers. Nefazodone was administered for 16 consecutive days, and nocturnal sleep, as well as multiple sleep latency test (MSLT), was monitored before, during, and after N administration. We found that N had no effect on any measured REM sleep variable including REM sleep duration, REM density, and nocturnal REM sleep distribution. Nefazodone also had no significant effect on nocturnal total sleep time or NREM variables, but increased daytime alertness measured by the MSLT. Since N is a potent serotonin reuptake blocker, the present findings that N had no effect on REM sleep cast doubt on the hypothesis that antidepressant drugs decrease REM sleep by increasing serotonergic neurotransmission. A review of other relevant work also casts doubt on this hypothesis.

Liaison between gynaecologists, microbiologists and genitourinary medicine clinics in the management of patients with genital chlamydia and gonococcal infections.

Inadequate treatment and follow-up of women with genital infection with Chlamydia trachomatis and Neisseria gonorrhoeae can cause long-term morbidity. Inadequate contact tracing can predispose to re-infection. As some women with genital infections present to agencies other than genitourinary medicine (GUM) clinics, improved liaison between these and GUM departments are important in safeguarding proper follow-up and contact tracing.
