ABSTRACT
Abstract Introduction Childhood trauma (CT) is known to be a vulnerability factor for schizophrenia, but the specific impacts of different trauma subtypes on the prognosis of these patients remains unclear. Objective To assess the relationships between the occurrence of overall CT and its subtypes with factors with known prognostic impact on schizophrenia, such as age at onset of symptoms, global functioning, and cognitive impairment in a sample of Brazilian patients. Methods One hundred and five stable patients diagnosed with schizophrenia according to DSM-5 criteria were evaluated using the Independent Living Skills Survey (ILSS; self-report global functioning), Schizophrenia Cognition Rating Scale (SCoRS; subjective cognitive impairment), and Childhood Trauma Questionnaire scales (CTQ; perceived overall CT, emotional neglect, physical neglect, physical abuse, and emotional and sexual abuse). Statistical analysis was performed with multivariate linear regression. Results After controlling for educational level and age, subjective cognitive impairment was directly correlated with overall perceived CT occurrence, emotional abuse, and sexual abuse. Self-report global functioning was inversely correlated with perceived overall CT occurrence, emotional abuse, and sexual abuse. Emotional abuse and physical abuse were also inversely correlated with age at onset of symptoms. Conclusions CT can be related to more severe prognoses in schizophrenia, impacting on early onset of symptoms, lower global functioning, and greater cognitive impairment. Subtypes of trauma can be associated with different prognostic risks.
ABSTRACT
Contexto: O transtorno bipolar tipo I está comumente associado a comorbidades clínicas e psiquiátricas, mas ainda há poucos dados disponíveis sobre pacientes brasileiros. Objetivos: O objetivo do presente estudo foi avaliar a prevalência de comorbidades clínicas e psiquiátricas em uma amostra brasileira de pacientes bipolares tipo I. O objetivo secundário foi investigar as associações de características clínico-demográficas e comorbidades com tentativas de suicídio. Métodos: Foram incluídos neste estudo 94 pacientes bipolares tipo I. O diagnóstico psiquiátrico foi determinado utilizando-se a avaliação Mini International Neuropsychiatric Interview (MINI-Plus). O diagnóstico de comorbidades clínicas foi baseado na história clínica e no acompanhamento de clínicos gerais. Resultados: As comorbidades mais prevalentes nos pacientes bipolares foram: transtorno de ansiedade generalizada (19,20 por cento), dependência de substâncias (43,60 por cento), hipertensão arterial (29,80 por cento), diabetes mellitus (17,00 por cento), dislipidemia (22,30 por cento) e hipotireoidismo (19,10 por cento). Não foram encontradas diferenças estatísticas em relação às características demográficas ou à prevalência de comorbidades nos grupos com e sem tentativa de suicídio. Conclusão: Pacientes bipolares atendidos em serviço psiquiátrico apresentam elevada prevalência de comorbidades psiquiátricas e clínicas. Nessa população, tentativas de suicídio não se associam com a presença de comorbidades ou características demográficas.
Background: Bipolar disorder type I is frequently associated with psychiatric and medical comorbidities, but data regarding Brazilian patients are lacking. Objectives: The aim of the present study was to evaluate the prevalence of psychiatric and medical comorbidities in a Brazilian sample of bipolar disorder patients type I. A secondary aim was to investigate the association of demographic characteristics and comorbidities with suicide attempts. Methods: Ninety four bipolar disorder type I patients were included in this study. Psychiatric diagnoses were performed following the Mini International Neuropsychiatric Interview (MINI-Plus) evaluation. The diagnosis of medical comorbidities was based on clinical history and general practice consultation. Results: The commonest comorbidities in bipolar disorder patients were generalized anxiety disorder (19.20 percent), substance dependence (43.60 percent), arterial hypertension (29.80 percent), diabetes mellitus (17.00 percent), dyslipidemia (22.30 percent) and hypothyroidism (19.10 percent). There were no differences in demographic characteristics or the prevalence of comorbidities when comparing patients with and without previous suicide attempt. Conclusion: Bipolar disorder patients from a psychiatric unit present higher prevalence of psychiatric and clinical comorbidities. Previous suicide attempts were not associated with comorbidities or demographic characteristics.
ABSTRACT
OBJETIVO: Pesquisas recentes têm implicado fatores imunes na patogênese de diversos transtornos neuropsiquiátricos. O objetivo do presente trabalho é revisar os trabalhos que investigaram a associação entre transtorno bipolar e alterações em parâmetros imunes. MÉTODOS: Artigos que incluíam as palavras-chave: "bipolar disorder", "mania", "immunology", "cytokines", "chemokines", "interleukins", "interferon" e "tumor necrosis factor" foram selecionados em uma revisão sistemática da literatura. As bases de dados avaliadas foram MedLine e Scopus, entre os anos de 1980 e 2008. RESULTADOS: Foram identificados 28 trabalhos que estudaram alterações imunes em pacientes com transtorno bipolar. Seis artigos investigaram genes relacionados à resposta imune; cinco, autoanticorpos; quatro, populações leucocitárias; 13, citocinas e/ou moléculas relacionadas à resposta imune e seis, leucócitos de pacientes in vitro. CONCLUSÕES: Embora haja evidências na literatura correlacionando o transtorno bipolar a alterações imunes, os dados não são conclusivos. O transtorno bipolar parece estar associado a níveis mais elevados de autoanticorpos circulantes, assim como à tendência à ativação imune com produção de citocinas pró-inflamatórias e redução de parâmetros anti-inflamatórios.
OBJECTIVE: Emerging research has implicated immune factors in the pathogenesis of a variety of neuropsychiatric disorders. The objective of the present paper is to review the studies that investigated the association between bipolar disorder and immune parameters. METHODS: Papers that included the keywords "bipolar to disorder", "mania", "immunology", "cytokines", "chemokines", "interleukins", "interferon" and "tumor necrosis factor" were selected in a systematic review of the literature. The evaluated databases were MedLine and Scopus in the period between 1980 and 2008. RESULTS: Twenty eight works were found. Six studies investigated immune response-related genes; five, auto-antibodies; four, leukocyte population; 13, cytokines and/or immune-related molecules; six, leukocytes in vitro. CONCLUSIONS: Although there is evidence in the literature correlating affective disorders with immune parameters, the results are still inconclusive. Bipolar disorder seems to be associated with increased levels of auto-antibodies as well as with a trend for increased immune activation with production of pro-inflammatory cytokines and reduction of the anti-inflammatory parameters.

A paciente MLC, de 46 anos, portadora de lupus eritematoso sistêmico e hipotireoidismo, evoluiu com plaquetopenia severa após o uso irregular de sulfametoxazol-trimetoprim. Foi Instituída terapêutica com transfusão de plaquetas, predinisone e pulsoterapia com metil- predinisona. A paciente apresentou resposta clínica tardia, no 26° dia após o início da pulsoterapia, evoluindo, porém, com complicações do tratamento, tais como infecções graves e hiperglicemia.
The patient MLe, 46 years old, female, with SLE and hypothy- roidism, developed important thrombocytopenia after irregular user of sulfonarnide. The treatment with platelets transfusions, predinisone and pulses with methylpredinisolone in high doses was iniriated. The patients demonstrated a late clinical response,at the twenty-sixth day aftes pulses. Complications of the treatment, like severe infections and hyperglicemia, ocurred.
