RESUMO
Patients with schizophrenia are eight times more likely than healthy individuals to become infected with the human immunodeficiency virus (hiv). Although in vitro studies provide some data on the interaction between antipsychotics and retroviral agents, there is a lack of in vitro data on this subject. We describe the case of a 35-year-old patient who suffered from schizophrenia, polydrug abuse and an hiv infection and who also had treatment-resistant psychosis. An interaction between the antiretroviral drug ritonavir and the antipsychotic olanzapine turned out to be the cause of the treatment resistance. As far as we know, this is the first report of such a clinically relevant interaction. We present a review of the current literature on this type of interaction.

The practice of coercive measures in psychiatry is controversial. Although some have suggested that it may be acceptable if patients are a danger to others or to themselves, others committed themselves to eliminate it. Ethical, legal and clinical considerations become more complex when the mental incapacity is temporary and when the coercive measures serve to restore autonomy. We discuss these issues, addressing the conflict between autonomy and beneficence/non-maleficence, human dignity, the experiences of patients and the effects of coercive measures. We argue that an appeal to respect autonomy and/or human dignity cannot be a sufficient reason to reject coercive measures. All together, these ethical aspects can be used both to support and to reject a non-seclusion approach. The total lack of controlled trials about the beneficial effects of coercive measures in different populations however, argues against the use of coercive measures.
