ABSTRACT The increased prevalence of diabetes in schizophrenia is partly attributed to antipsychotic treatment, in particular second-generation antipsychotics, but the evidence has not been systematically reviewed.
Systematic review and meta-analysis comparing diabetes risk for different antipsychotics in people with schizophrenia.
We searched MEDLINE, PsycINFO, EMBASE, International Pharmaceutical Abstracts, CINAHL and Web of Knowledge until September 2006. Studies were eligible for inclusion if the design was cross-sectional, case-control, cohort or a controlled trial in individuals with schizophrenia or related psychotic disorders, where second-generation antipsychotics (defined as clozapine, olanzapine, risperidone and quetiapine) were compared with first-generation antipsychotics and diabetes was an outcome. Data were pooled using random effects inverse variance weighted meta-analysis.
Of the studies that met the inclusion criteria (n=14), 11 had sufficient data to include in the meta-analysis. Four of these were retrospective cohort studies. The relative risk of diabetes in patients with schizophrenia prescribed one of the second-generation v. first-generation antipsychotics was 1.32 (95% CI 1.15-1.51). There were insufficient data to include aripiprazole, ziprasidone and amisulpride in this analysis.
There is tentative evidence that the second-generation antipsychotics included in this study are associated with a small increased risk for diabetes compared with first-generation antipsychotics in people with schizophrenia. Methodological limitations were found in most studies, leading to heterogeneity and difficulty interpreting data. Regardless of type of antipsychotic, screening for diabetes in all people with schizophrenia should be routine.

    ABSTRACT: Resumen El cambio de antipsicóticos es un hecho frecuente en la práctica clínica y está sujeto a potenciales complicaciones clínicamente relevantes. Un grupo de expertos seleccionados por la Sociedad Española de Psiquiatría y la Sociedad Española de Psiquiatría Biológica ha revisado y discutido las pruebas provenientes de los ensayos clínicos y otros artículos relevantes para llegar a unas recomendaciones de consenso sobre el cambio de antipsicóticos. En este artículo se revisa toda la información que ha dado lugar a esas recomendaciones y que incluye: indica-ciones y contraindicaciones del cambio de antipsicóticos, aspectos farmacológicos, estrategias de cambio, el cambio por motivos de eficacia, el cambio por motivos de tolerabilidad (inclu-yendo los síntomas extrapiramidales y la discinesia tardía, el aumento de peso, los trastornos metabólicos, la hiperprolactinemia, la disfunción sexual, la sedación persistente y la prolon-gación del QT), el cambio por problemas de cumplimiento y el cambio de antipsicóticos en el trastorno bipolar. © 2011 SEP y SEPB.

    ABSTRACT: People of color with serious mental illnesses experience high rates of morbidity and mortality. Patient navigators, developed for cancer care, may help this group benefit from integrated care. This review examined patient navigators' key ingredients for cancer care for relevance to patients of color for application of peer services to psychiatric goals. Among cancer patients, navigators lead to greater treatment engagement and improved health outcomes for ethnic minority groups. Research also suggests peers can improve integrated care by providing effective psychiatric services to individuals with mental illness. Ongoing research examines peer navigators' impact on integrated care for patients of color.

    ABSTRACT: The primary objectives in the treatment of schizophrenia are to reduce the frequency and severity of psychotic exacerbation, ameliorate a broad range of symptoms, and improve functional capacity and quality of life. Treatment includes pharmacotherapy and a range of psychosocial interventions. Antipsychotics are the cornerstone of pharmacological treatment for schizophrenia. The sixty-five antipsychotics available in the world are classified into two major groups: first-generation (conventional) agents (FGAs) and second-generation (atypical) agents (SGAs). Whereas clozapine is found to be more efficacious than other agents among otherwise treatment-refractory schizophrenia patients, other differences in efficacy between antipsychotic agents are minor. There are, however, pronounced differences in adverse effect profiles among the 65 antipsychotic medications. Although the 14 SGAs differ “on average” from the 51 FGAs in terms of being associated with a lower risk of EPS and greater risk of metabolic side-effects, substantial variation within the two classes with regards to both risks and other relevant clinical properties undermines the categorical distinction between SGAs and FGAs. Choice of antipsychotic medication should be based on prior treatment response, individual preference, medical history and individual patient vulnerabilities. An individualized treatment approach with ongoing risk-benefit monitoring and collaborative decision-making is outlined. Even as rapid neuroscience advances promise revolutionary improvements in the future, a thoughtful and disciplined approach can provide enhanced outcomes for all schizophrenia patients today.
