It has been suggested that HIV infection is associated with an increas
ed risk of suicidal behaviour. This paper reviews the literature on su
icide in patients with HIV disease and discusses methodological proble
ms encountered in studying the incidence of suicide in this population
. A snowballing method was used to identify cases of suicide in patien
ts who were receiving treatment for HIV disease in a central London he
alth district. The possible under detection of suicides among AIDS pat
ients is considered. The six case reports are described to illustrate
the clinical and psychosocial characteristics of suicides, and they ar
e discussed in relation to other findings on suicide in patients with
HIV disease and other physical illnesses.
