A dopamine receptor D2 genetic polymorphism associated with transition to mental disorders in a cohort of individuals with at-risk mental state for psychosis

Objectives: To test the association of 45 single nucleotide polymorphisms (SNPs) with transition to psychiatric disorders in a cohort of individuals at ultrahigh risk (UHR) mental state for psychosis. Methods: Through general population screening, 88 non-help-seeking UHR subjects and 130 healthy control individuals were genotyped for 45 SNPs related to psychosis. They were followed for a mean of 2.5 years, and conversion to psychotic and to general psychiatric disorders was assessed. Genotype frequencies between controls, converters, and non-converters were analyzed. Results: There were no differences in sociodemographics between controls and UHR. Also, UHR converters and non-converters had no differences in their baseline symptoms scores. The dopamine receptor D2 gene (DRD2) SNP rs6277 was significantly more common among UHR who transitioned to psychosis (p < 0.001) and to UHR who transitioned to any psychiatric disorders (p = 0.001) when compared to UHR who did not transition. The rs6277 T allele was related to psychiatric morbidity in a dose-response fashion, being significantly more frequent in UHR converters than UHR non-converters and control subjects (p = 0.003). Conclusion: Our findings suggest that rs6277 could potentially constitute a genetic marker of transition to psychiatric disorders in subjects with at-risk mental states, warranting further investigation in larger samples.

Influence of migration on the thought process of individuals at ultra-high risk for psychosis

Objective: To assess the influence of migration on the psychopathological presentation of individuals at ultra-high risk for psychosis (UHR) in São Paulo, Brazil. Methods: This study is part of the Subclinical Symptoms and Prodromal Psychosis (SSAPP) project, a cohort study in São Paulo, Brazil, designed to follow individuals at UHR. After screening with the Prodromal Questionnaire (PQ) and a clinical interview, the Global Assessment of Functioning (GAF) was administered, a neuropsychological assessment was performed, sociodemographic and migration data were obtained. We then analyzed UHR individuals who had migration data to see if migration had any effect on their cognition and psychopathology. Chi-square tests were used for categorical variables, and Student's t test or analysis of variance (ANOVA) were used for nonparametric and parametric distributions, respectively. Results: The sample was composed of 42 at-risk subjects, of whom 5 had a migration history in the past two generations. Those with migration history showed significantly more formal thought disturbances (p = 0.012) and sleeping problems (p = 0.033) compared to those without. Conclusions: Our data reinforce migration as a risk factor for psychosis in developing countries as well, and highlights the importance of studying the specific effect of this factor in UHR psychopathology.

Atitudes de profissionais de saúde mental em relação a indivíduos com esquizofrenia: uma comparação transcultural entre Suíça e Brasil / Attitudes of mental health professionals towards persons with schizophrenia: a transcultural comparison between Switzerland and Brazil

CONTEXTO: A estigmatização é uma questão importante no tratamento e no curso da esquizofrenia. A manutenção de atitudes estigmatizantes pode estar relacionada a fatores socioculturais. OBJETIVOS: Comparar atitudes estigmatizantes de profissionais de saúde mental em países culturalmente diversos: Brasil e Suíça. MÉTODOS: Foram analisados dados de duas grandes pesquisas sobre o estigma na Suíça e no Brasil, focando-se no desejo de distância social em relação a indivíduos com esquizofrenia e atitudes de profissionais de saúde mental em relação à aceitação de efeitos colaterais do tratamento psicofarmacológico. RESULTADOS: Profissionais de saúde mental suíços apresentaram níveis significativamente mais elevados de distância social do que suas contrapartes brasileiras. Houve também um efeito fraco de idade, bem como um efeito da interação entre a origem e a idade. Com relação à aceitação de efeitos colaterais, a influência da origem foi bastante fraca. Com exceção do risco de dependência dos psicotrópicos, a aceitação dos profissionais suíços a efeitos colaterais de longa duração foi significativamente maior do que a de seus colegas no Brasil. CONCLUSÕES: A forte associação entre origem e distância social pode estar relacionada à formação sociocultural dos profissionais de saúde mental; em comparação com a Suíça, o Brasil é muito heterogêneo em termos de estrutura étnica e socioeconômica. A aceitação de efeitos colaterais pode também estar relacionada com os medicamentos mais sofisticados (ou seja, drogas antipsicóticas de nova geração) comumente usados na Suíça.

BACKGROUND: Stigmatization is an important issue in the treatment and course of schizophrenia. The maintenance of stigmatizing attitudes may be related to socio-cultural factors. OBJECTIVES: To compare stigmatizing attitudes of mental health professionals in the culturally diverse countries Brazil and Switzerland. METHODS: We analyzed data of two broad stigmatization surveys from Switzerland and Brazil by focusing on the social distance and attitudes of mental health professionals towards the acceptance of side effects of psychopharmacological treatment. RESULTS: Swiss mental health professionals showed significantly higher levels of social distance than their Brazilian counterparts. There was also a weak effect of age as well as an interaction effect between origin and age. With respect to the acceptance of side effects, the effect of origin was rather weak. With the exception of drug dependence, Swiss professionals' acceptance of long-lasting side effects was significantly higher than for their counterparts in Brazil. DISCUSSION: The strong association between origin and social distance may be related to the socio-cultural background of the mental health professionals. In comparison with Switzerland, Brazil is very heterogeneous in terms of ethnicity and socio-economic structure. The distinct acceptance of side effects may additionally be related to the more sophisticated medicaments (i.e. new generation of antipsychotic drugs) commonly used in Switzerland.

O estigma atribuído pelos psiquiatras aos indivíduos com esquizofrenia / Psychiatrists' stigma towards individuals with schizophrenia

CONTEXTO: A literatura acerca da maneira como a população geral estigmatiza indivíduos com distúrbios mentais aumentou consideravelmente nas últimas décadas. Mas a dúvida sobre se os psiquiatras também estigmatizam seus pacientes ainda permanece. OBJETIVO: O presente estudo visou avaliar as atitudes de psiquiatras brasileiros em relação aos indivíduos com esquizofrenia. MÉTODOS: Dos cerca de 6.000 participantes do Congresso Brasileiro de Psiquiatria em 2009, 1.414 psiquiatras concordaram em participar do estudo. Entrevistas face a face foram realizadas utilizando um questionário que avaliava o estigma em três dimensões: estereótipos, distância social e preconceito, todas relacionadas a alguém com esquizofrenia. Opinião sobre medicações psicotrópicas e tolerância aos efeitos colaterais também foram avaliadas. Dados sociodemográficos e profissionais foram coletados. RESULTADOS: Psiquiatras brasileiros tenderam a estereotipar negativamente pessoas com esquizofrenia. Estereótipos negativos correlacionaram-se com uma melhor opinião sobre medicações psicotrópicas e com maior tolerância a efeitos colaterais. Idade maior correlacionou-se com estereótipos positivos e com menor preconceito. CONCLUSÃO: Os psiquiatras estigmatizam indivíduos com esquizofrenia e possivelmente têm certa dificuldade em admitir esse fato. Campanhas antiestigma para profissionais de saúde mental devem ser promovidas.

BACKGROUND: Literature on how the general population stigmatizes individuals with mental disorders has increased considerably over the last decades. But the question remains if psychiatrists also stigmatize their patients. OBJECTIVE: The present study aimed to assess Brazilian psychiatrists' attitude towards individuals with schizophrenia. METHODS: Out of the approximately 6,000 participants of the 2009 National Psychiatry Congress in Brazil, 1,414 psychiatrists agreed to undergo the survey. Face-to-face interviews were conducted using a questionnaire that assessed stigma in three dimensions: stereotypes, social distance and prejudice towards a person with schizophrenia. Their opinion on psychotropic drugs and tolerance of side-effects were also assessed. Socio-demographic and professional data were collected. RESULTS: Brazilian psychiatrists tend to negatively stereotype individuals with schizophrenia. More negative stereotypes correlated with a positive opinion on psychotropic drugs and with a higher tolerance of side-effects. Higher age was correlated with positive stereotyping and with less prejudice. DISCUSSION: Psychiatrists stigmatize individuals with schizophrenia and possibly find it difficulty admit this fact. Anti-stigma campaigns among mental health professionals should be promoted.
