Psychiatric
Issues in the Management of Patients With HIV Infection [Treisman
GJ et al. JAMA 2001;286:2857] The
authors review the experience with the AIDS Psychiatry Service at
the Johns Hopkins Moore Clinic. This review concerns the HIV-associated
issues with the four main categories of psychiatric disorders: Brain
diseases, personality disorders, addiction and problems with life
circumstances.
Psychiatric
diseases associated with HIV: Major
depression is the greatest concern because it is common, devastating,
and responds well to treatment with antidepressant drugs. The authors
note that about 20% of patients who present to the AIDS Psychiatry
Service have major depression and they estimate that about 60% of
HIV-infected patients have a depressive episode at some time during
their illness. The major source of confusion in diagnosis is an
"adjustment disorder" which is characterized as "demoralization."
Patients with major depression are considered to have brain disease
whereas demoralization is a response to life circumstances. The
former responds well to antidepressants, but demoralization probably
responds best to psychotherapy. The authors report that antidepressant
therapy with psychotherapy provides benefit to 85% of patients and
restores half of them to baseline [Psychosomatics 1997;38:423].
The use of antidepressants is complicated by the drug interactions
associated with HAART, which have been described in detail previously
by these authors [CID 2001;33:847]. The following two tables
provide a comparison of depression vs. demoralization and a summary
of the most important antidepressant agents with dosage and major
interactions, which generally reflect competition for, or induction
of the P450 enzymes.

There are two
additional dimensions to depression that are important to emphasize:
First, depression is associated with poor adherence to HAART [Ann
Intern Med 2000;133:21]; second, there is the confusion distinguishing
depression from AIDS dementia. AIDS dementia is a subcortical dementia,
which produces a flat apathetic state and is best treated with HAART.
Personality
disorders: The authors characterize two personality dimensions,
stability-instability and introversion-extroversion, both of which
exert influence on and can cause difficulties with a patients' adherence
to treatment regimens. The authors note that most health workers
are introverts making them, "consequence-avoidant," but
most HIV-infected patients are extroverts who tend to be insensitive
to consequences. This difference often poses difficulties with effective
communication. The authors state that the goal of therapy is "a
series of gradual behavior changes sustained over several years."
Addictions:
This is sometimes referred to as "motivated behavior,"
to encompass both biologic and volitional aspects. Management of
substance abuse requires a team of clinicians.
Problems with
life circumstances: This category includes demoralization and
risk of suicide. The interventions with the best results are counseling,
support groups, family groups, drop in centers and advocacy programs.
Severe demoralization usually requires psychotherapy by a trained
provider.
