Clinical management of HIV disease in intravenous drug-users.

Intravenous drug-users comprise a major group of HIV-infected individuals in the developed world and, whilst progression of HIV disease in them appears little different from other risk groups, their medical presentations may be altered by continuing drug use. Drug-users are particularly susceptible to bacterial infections irrespective of their HIV status; they may present with symptoms directly caused by their drugs, which can be difficult to differentiate from non-drug-related causes and may closely resemble symptoms directly attributable to HIV. In addition, the life style associated with drug use can make compliance difficult, but in clinics combining HIV care and methadone prescribing these problems can be overcome.
