Use of clozapine in Brazilian patients with Parkinson's disease / Uso da clozapina em pacientes brasileiros com doença de Parkinson

Clozapine has been used as an attempt to manage levodopa complications in advanced Parkinson's disease (PD). To investigate the use of clozapine in this context in a Brazilian sample, a retrospective chart review was carried out at the Movement Disorders Clinic from the Federal University of Minas Gerais. This study enrolled 43 PD patients who used or were in use of clozapine. Patients had a mean age of 64 years and a mean UPDRS score of 55. Clozapine was indicated for dyskinesias in 17 patients, for psychosis in 15 and for both reasons in 11. The average maximum dose was 70 mg/day. Twenty six patients used it for a mean of 3.5 years. Twenty nine presented an improvement of their condition, 9 remained clinically stable. Twenty subjects interrupted the use of clozapine, being 9 due to adverse effects. Clozapine may play a role in the management of motor and psychiatric complications in PD, but it is associated with low tolerability.

A clozapina vem sendo utilizada na doença de Parkinson (DP) avançada para controle das complicações causadas pela levodopa. Com o objetivo de investigar o emprego da clozapina nesse contexto em amostra de pacientes brasileiros, um estudo retrospectivo foi realizado no Ambulatório de Distúrbios do Movimento da Universidade Federal de Minas Gerais. Este estudo incluiu 43 pacientes que usaram clozapina, apresentando idade média de 64 anos e uma média de 55 pontos no UPDRS. A clozapina foi indicada para discinesias em 17 pacientes, para psicose em 15 e para ambos os motivos em 11. A média da dose máxima empregada foi de cerca de 70 mg/dia. Vinte e seis pacientes usaram a medicação por uma média de 3,5 anos. Houve melhora do quadro clínico em 29 pacientes, 9 permaneceram com quadro clínico estático. O tratamento foi interrompido em 20 pessoas, sendo 9 por efeitos adversos. Apesar de a clozapina ser eficaz no controle das complicações motoras e psiquiátricas na DP, seu uso está associado com baixa tolerabilidade.

Psychosis during peginterferon-alpha2a and ribavirin therapy: case report

Pegylated Interferon-alpha, combined with ribavirin, gives high sustained virological response in patients with hepatitis C virus, an important public health problem and one of the most frequent chronic infectious diseases worldwide. Though it has therapeutic benefits, treatment with IFN-alpha may be complicated by various side effects, especially symptoms of major depression and acute mania. Psychosis is a rare side effect, and its management usually includes discontinuation of IFN-alpha. We report a case of psychotic disorder that occurred during therapy with pegylated Interferon-alpha given associated with ribavirin. After good response to psychiatric treatment, it became possible to finish the anti-viral therapy.

A 4-week, double-blind comparison of olanzapine with haloperidol in the treatment of amphetamine psychosis.

OBJECTIVE: To compare the efficacy and tolerability of olanzapines and haloperidol in treating patients with amphetamine psychosis. MATERIAL AND METHOD: Fifty-eight patients experiencing episode of amphetamine psychosis were randomly assigned to olanzapine (N=29) or haloperidol (N=29) in 1:1 (olanzapine: haloperidol) ratio. All patients started with 5-10 mg/day of the study drug; after each 7-day period, the study drug could be adjusted in 5-mg increments or decrements within the allowed dose range of 5-20 mg/day during the 4-week double-blind period. RESULTS: Clinical response was seen in both treatment groups since the first week. Ninety three percent of the olanzapine patients (N=27 of 29) and 79.3% of the haloperidol patients (N=23 of 27) were clinically improved at endpoint. These differences were not statistically significant (p=0.25). The Simpson-Angus total score change from baseline to endpoint reflected no extrapyramidal symptoms among the olanzapine-treated patients (median=0.0, range=0.0). In contrast, worsening occurred among the haloperidol-treated patients (median=0.2, range=0.0-3.1). The differences of mean change in Simpson Angus Scale significantly favored olanzapine (p<0.01). Change to endpoint on the Barnes Akathisia Scale showed that olanzapine-treated patients' scores were close to the baseline (median=0.0, range=-1.0-0.0), whereas haloperidol-treated patients' scores worsened from the baseline (median=0.0, range=-1.0-3.0). This difference was statistically significant (p=0.02). CONCLUSION: Both olanzapine and haloperidol were efficacious in the treatment of patients with amphetamine psychosis. Olanzapine was superior to conventional neuroleptic haloperidol in treatment safety with lower frequency and severity of extrapyramidal symptoms.

Psychosis during disulfiram therapy for alcoholism.

Fifty-two patients (51 males, one female) of alcohol dependence/abuse diagnosed according to DSM 111 R1 were registered for disulfiram treatment and were admitted for a 4-week period. No alcohol challenge test was given during their hospital stay. Disulfiram tablets were administered 250 mg twice daily after food. After one week's hospital stay with disulfiram therapy they were sent home to be followed up initially after 15 days and later on once a month. Six male patients developed psychotic symptoms. All of them had shown a mood disorder but no thought disorder was observed. Psychotic symptoms remitted completely after withdrawing disulfiram and then a short course of antipsychotic therapy was given, except in one patient who had to be given lithium for remission of symptoms.
