Objetivo Investigar as características psicométricas de uma versão traduzida da escala, propondo uma Versão Revisada que atenda aos critérios de adaptação transcultural para o contexto brasileiro. Métodos Este estudo incluiu 231 sujeitos – deprimidos (45,5%), bipolares (7,8%) e saudáveis (46,7%) – que participaram de uma pesquisa epidemiológica no sul do Brasil. A avaliação de transtornos mentais foi realizada por meio da Clinical Interview for DSM-IV (SCID) e uma versão traduzida da Escala de Avaliação de Depressão de Hamilton (HAM-D), que habitualmente vem sendo utilizada no país sem estudos de adaptação. Resultados Identificou-se o ponto de corte (9 pontos) para discriminar a presença ou não de sintomas de depressão pela análise da curva ROC, resultando em uma sensibilidade e especificidade de 90 e 91%, respectivamente. A validade interna foi investigada pela análise fatorial e consistência dos itens. Dos 17 itens originais, apenas o item que avalia a “consciência do transtorno” não apresentou carga fatorial satisfatória para avaliar depressão geral e foi eliminado; os 16 restantes agruparam-se em cinco dimensões, denominadas: Humor deprimido, Anorexia, Insônia, Somatização e Ansiedade, as quais, com exceção da última, mostraram homogeneidade nos seus construtos (coeficientes alfa entre 0,66 e 0,78). Na análise de conteúdo dos itens, cinco especialistas sugeriram alterações redacionais em sete itens. Conclusão O estudo determina um ponto de corte diferente do original e evidencia características psicométricas favoráveis para a utilização da escala no Brasil.

Objective To investigate the psychometric characteristics of a translated version of the scale, proposing a reviewed version in order to attend the transcultural adaptation criteria. Methods This study included 231 subjects – depressed (45.5%), bipolar (7.8%), and healthy (46.7%) – who participated of an epidemiological research in southern Brazil. The evaluation of mental disorders was made through Clinical Interview for DSM-IV (SCID) and a translated version of the Hamilton Scale (HAM-D), usually utilized in Brazil without adaptation studies. Results The ROC curve analysis identified the cutoff (9 points) to discriminate the presence or absence of depression, resulting in a sensibility and specificity of 90 and 91%, respectively. The internal validity was investigated by the factorial analysis and consistence of the items. It was observed that all 17 original items, except “Consciousness”, presented psychometric quality to evaluate general depression, and that there were five dimensions underling those 16 items: Depressed humor, Anorexia, Insomnia, Somatization, and Anxiety, and all of them, excepting the last, showed homogeneity in their constructs (alpha coefficients between 0.66 and 0.78). On content analysis, five specialists suggested editing changes in seven items. Conclusion This study determinates a different cutoff and psychometric evidences favourable to the use of HAM-D in Brazil.

Objective: High cardiovascular mortality rates have been reported in patients with bipolar disorder (BD). Studies indicate that matrix metalloproteinases (MMPs) are implicated in cardiovascular diseases. We evaluated the expression pattern of MMP-2 and MMP-9 in blood from patients with BD during acute mania and after euthymia, in comparison with healthy controls. Methods: Twenty patients and 20 controls were recruited and matched for sex and age. MMP messenger RNA (mRNA) levels were measured using real-time quantitative polymerase chain reaction (PCR). Body mass index (BMI) was calculated for all subjects. Results: There were no significant differences in MMP-2 and MMP-9 mRNA expression between patients and controls. mRNA levels were not significantly different during mania and euthymia. However, MMP-2 mRNA levels were negatively associated with BMI in BD patients and positively associated with BMI in controls. There was no difference in the pattern of MMP-9 expression between patients and controls. Conclusions: Our results suggest a different pattern of association between MMP-2 and BMI in BD patients as compared with controls. Despite some study limitations, we believe that the role of MMPs in BD should be further investigated to elucidate its relationship with cardiovascular risk.

Objective: To evaluate serum levels of different biomarkers associated with cardiovascular disease in patients with bipolar disorder (BD). Patients were prospectively evaluated in two separate instances: during acute mania and after remission of manic symptoms. All measurements were compared with those of healthy controls. Methods: The study included 30 patients with BD and 30 healthy controls, matched for gender and age. Biochemical parameters evaluated included homocysteine (Hcy), folic acid, vitamin B12, ferritin, creatine kinase (CK) and C-reactive protein (CRP). Results: Hcy levels were significantly higher in the BD patients, both during mania and after achieving euthymia. When Hcy was adjusted for body mass index, there was no significant difference between patients and controls. Ferritin was the only marker that showed a significant decrease during mania when compared to both euthymic patients and controls. There were no significant differences for folate, vitamin B12, CK and CRP. Conclusions: These findings do not show an association between alterations of markers of cardiovascular risk during manic episodes. Further studies are necessary to determine factors and mechanisms associated with cardiovascular risk in patients with BD.

OBJETIVO: Verificar vivências precoces de abuso e negligência na infância entre jovens com transtorno bipolar (TB), transtorno depressivo maior (TDM) e controles populacionais. MÉTODO: Estudo de caso-controle aninhado a um estudo transversal de base populacional. A confirmação do diagnóstico foi realizada por meio de entrevista clínica estruturada para transtornos de eixo I do DSM-IV (SCID) e os eventos traumáticos foram verificados pelo Questionário sobre traumas na infância (CTQ). RESULTADOS: A amostra foi composta por 231 jovens, sendo 95 indivíduos no grupo controle, 82 com TDM e 54 com TB (32 do tipo I e 22 do tipo II). A prevalência de trauma na infância foi de 42,2%, sendo 54,7% entre aqueles com TB, 62,2% entre os jovens com TDM e 18,1% entre o grupo controle. Os jovens com TB ou TDM apresentaram maiores médias no CTQ total e entre seus componentes quando comparados aos jovens do grupo controle, exceto o componente abuso sexual, em que se observou diferença estatística apenas entre o grupo controle e o grupo de jovens com transtorno bipolar. CONCLUSÃO: O relato de vivências traumáticas precoces foi mais presente entre os jovens com transtornos de humor do que na população geral, confirmando o que a literatura traz sobre o tema. Nesse sentido, as vivências de trauma na infância parecem contribuir para o aparecimento dos transtornos de humor.

OBJECTIVE: To verify early experiences of childhood abuse and neglect among young with bipolar disorder (BD), major depression (MDD), and controls. METHOD: Case-control study nested to a population-based cross-sectional study. The diagnosis was performed via the structured clinical interview for DSM-IV Axis I Disorders (SCID). Traumatic events were analyzed using the Portuguese version - Questionário sobre Traumas na Infância (CTQ) - based on the Childhood Trauma Questionnaire. RESULTS: The sample comprised 231 adolescents with 95 individuals in the control group, 82 with MDD and 54 with BD (32 of type I and 22 type II). The prevalence of trauma or violence in childhood was 42.2%; among those, 54.7% had BD, 62.2% had MDD and 18.1% were in the control group. Young people with BD or MDD obtained higher means in total CTQ and among their components when compared with those in the control group. DISCUSSION: Reports on early traumatic experiences were more frequent among young people with mood disorders than in the general population, corroborating the literature on the subject. In this sense, the traumatic experiences during childhood seemed to contribute to the onset of the disorder.
