Abstract Background Emerging evidence indicates that inflammation plays an important role as a mechanism underlying mental disorders. However, most of the research on inflammatory mechanisms focuses on serum levels of interleukins and very few studies have investigated molecules that initiate and expand innate immune pathways such as damage-associated molecular patterns (DAMPs). Objectives This study investigated the levels of DAMPs among patients diagnosed with major depressive disorder (MDD), bipolar disorder (BD) I and II, schizophrenia (SCZ), and generalized anxiety disorder (GAD). We quantified serum levels of heat shock proteins (HSPs) 70 and 60 and of S100 calcium-binding protein B (S100B). Methods Serum levels of HSP70, HSP60, and S100B were assessed in a sample of participants with psychiatric disorders (n = 191) and a control group (CT) (n = 59) using enzyme-linked immunosorbent assay (ELISA). Results Serum HSP70 concentrations were significantly higher in the MDD group compared to the CT, SCZ, and BD groups. The GAD group had higher concentrations of HSP70 than the SCZ group. Exploring associations with medications, lithium (p = 0.003) and clozapine (p = 0.028) were associated with lower HSP70 levels. Approximately 64% of the sample had DAMPs levels below the limits of detection indicated by the respective ELISA kit. Conclusion This was the first study to assess DAMPs levels in a transdiagnostic sample. Our preliminary findings suggest that HSP70 may be associated with MDD pathophysiology. Medications such as lithium and clozapine were associated with lower HSP70 levels in BD and SCZ groups, respectively. Therefore, it is worth mentioning that all participants were medicated and many psychotropic drugs exert an anti-inflammatory effect, possibly reducing the signs of inflammation.

Abstract Introduction Irritability has both mood and behavioral manifestations. These frequently co-occur, and it is unclear to what extent they are dissociable domains. We used confirmatory factor analysis and external validators to investigate the independence of mood and behavioral components of irritability. Methods The sample comprised 246 patients (mean age 45 years; 63% female) from four outpatient programs (depression, anxiety, bipolar, and schizophrenia) at a tertiary hospital. A clinical instrument rated by trained clinicians was specifically designed to capture irritable mood and disruptive behavior dimensionally, as well as current categorical diagnoses i.e., intermittent explosive disorder (IED); oppositional defiant disorder (ODD); and an adaptation to diagnose disruptive mood dysregulation disorder (DMDD) in adults. Confirmatory factor analysis (CFA) was used to test the best fitting irritability models and regression analyses were used to investigate associations with external validators. Results Irritable mood and disruptive behavior were both frequent, but diagnoses of disruptive syndromes were rare (IED, 8%; ODD, 2%; DMDD, 2%). A correlated model with two dimensions, and a bifactor model with one general dimension and two specific dimensions (mood and behavior) both had good fit indices. The correlated model had root mean square error of approximation (RMSEA) = 0.077, with 90% confidence interval (90%CI) = 0.071-0.083; comparative fit index (CFI) = 0.99; and Tucker-Lewis index (TLI) = 0.99, while the bifactor model had RMSEA = 0.041; CFI = 0.99; and TLI = 0.99 respectively). In the bifactor model, external validity for differentiation of the mood and behavioral components of irritability was also supported by associations between irritable mood and impairment and clinical measures of depression and mania, which were not associated with disruptive behavior. Conclusions Psychometric and external validity data suggest both overlapping and specific features of the mood vs. disruptive behavior dimensions of irritability.

OBJETIVOS: O objetivo do presente estudo foi investigar a validade de construto da Assessment of Countertransference Scale (ACS) no atendimento a vítimas de trauma, pela identificação de construtos latentes subjacentes dos itens medidos e sua homogeneidade. MÉTODOS: A ACS avalia 23 sentimentos de CT em três fatores: proximidade, rejeição e indiferença. A ACS foi aplicada a 50 residentes de psiquiatria após a primeira consulta com 131 vítimas de trauma selecionadas consecutivamente durante 4 anos. A ACS foi analisada por análise fatorial exploratória (AFE) e confirmatória (AFC), consistência interna e validade convergente-discriminante. RESULTADOS: Apesar do fato dos itens de proximidade terem obtido os escores mais altos, a AFE demonstrou que o fator de rejeição (24% da variância, α = 0,88) apresentou uma intercorrelação mais consistente dos itens, seguido pela proximidade (15% da variância, α = 0,82) e um fator distinto, tristeza (9% da variância, α = 0,72). Foi proposta, portanto, uma versão modificada. Na comparação entre a versão original e a proposta, a AFC detectou índices de adequação melhores para a versão proposta (GFI = 0,797, TLI = 0,867, CFI = 0,885 vs . GFI = 0,824, TLI = 0,904, CFI = 0,918). CONCLUSÕES: A ACS é um instrumento promissor para a avaliação de sentimentos de CT, tornando seu uso válido para a avaliação durante o cuidado de vítimas de trauma.

OBJECTIVES: The aim of the present study was to investigate the construct validity of the Assessment of Countertransference Scale (ACS) in the context of the trauma care, through the identification of the underlying latent constructs of the measured items and their homogeneity. METHODS: ACS assesses 23 feelings of CT in three factors: closeness, rejection and indifference. ACS was applied to 50 residents in psychiatry after the first appointment with 131 victims of trauma consecutively selected during 4 years. ACS was analyzed by exploratory (EFA) and confirmatory (CFA) factor analysis, internal consistence and convergent-discriminant validity. RESULTS In spite of the fact that closeness items obtained the highest scores, the EFA showed that the factor rejection (24% of variance, α = 0.88) presented a more consistent intercorrelation of the items, followed by closeness (15% of variance, α = 0.82) and, a distinct factor, sadness (9% of variance, α = 0.72). Thus, a modified version was proposed. In the comparison between the original and the proposed version, CFA detected better goodness-of-fit indexes for the proposed version (GFI = 0.797, TLI = 0.867, CFI = 0.885 vs. GFI = 0.824, TLI = 0.904, CFI = 0.918). CONCLUSIONS: ACS is a promising instrument for assessing CT feelings, making it valid to access during the care of trauma victims.

OBJETIVOS: Investigar a associação entre contratransferência (CT) no atendimento psiquiátrico inicial de vítimas de trauma e desfechos do tratamento. MÉTODO: A contratransferência de 50 terapeutas foi avaliada através da Assessment of Countertransference Scale após o primeiro atendimento de 131 vítimas de trauma (83% mulheres, idade entre 15 e 64 anos) selecionadas consecutivamente durante 4 anos. Foram avaliadas características demográficas e clínicas dos pacientes, e investigaram-se seus correlatos com os sentimentos contratransferenciais dos terapeutas. Os pacientes foram acompanhados ao longo do tratamento para verificar a associação entre a CT e o desfecho do tratamento, operacionalizado como alta ou abandono. RESULTADOS: A mediana de consultas realizadas foi 5 [4; 8], faltas 1 [0; 1] e taxa de abandono 34,4%. As características demográficas e clínicas dos pacientes dos grupos alta e abandono foram similares. Na análise multivariada, identificou-se que pacientes com relato de trauma na infância tiveram uma chance 61% menor de abandonar o tratamento que pacientes sem relato de trauma na infância (OR = 0,39; p = 0,039; IC 95% 0,16-0,95). Não foi detectada associação entre sentimentos contratransferenciais iniciais com os desfechos do tratamento. Conclusões: A CT no atendimento inicial de vítimas de trauma não esteve associada ao desfecho do tratamento. Estudos futuros devem avaliar a modificação da CT ao longo do tratamento e seu impacto sobre os desfechos.

OBJECTIVES: To investigate the association between feelings of countertransference (CT) at the early psychiatric care provided to trauma victims and treatment outcome. METHOD: The Assessment of Countertransference Scale was used to access CT after the first medical appointment. Fifty psychiatric residents cared for 131 trauma victims of whom 83% were women, aged 15 to 64 years. Patients had been consecutively selected over 4 years. Were evaluated the clinical and demographic characteristics of patients and the correlation with the therapists' CT feelings. Patients were followed-up during treatment to verify the association between initial CT and treatment outcome, defined as discharge and dropout. RESULTS: The median number of appointments was 5 [4; 8], absences 1 [0; 1], and the dropout rate was 34.4%. Both groups, namely the discharge group and the dropout group, shared similar clinical and demographic characteristics. A multivariate analysis identified that patients with a reported history of childhood trauma were 61% less likely to dropout from treatment than patients with no reported history of childhood trauma (OR = 0.39, p = 0.039, CI95% 0.16-0.95). There was no association between initial CT and treatment outcome. CONCLUSIONS: In this sample, CT in the initial care of trauma victims was not associated with treatment outcome. Further studies should assess changes in CT during treatment, and how such changes impact treatment outcome.

OBJETIVO: O objetivo do estudo foi avaliar os níveis séricos do fator neurotrófico derivado do cérebro em um paciente com transtorno de estresse pós-traumático e em um paciente com transtorno de estresse agudo antes e após o tratamento, comparando esses níveis aos de controles saudáveis. MÉTODO: Os níveis do fator neurotrófico derivado do cérebro, a Escala Davidson de Trauma, o Inventário de Depressão de Beck, a Avaliação do Funcionamento Global e a Impressão Clínica Global foram medidos antes e após seis semanas de tratamento. RESULTADOS: Os níveis de fator neurotrófico derivado do cérebro foram maiores nos pacientes, quando comparados aos controles, antes do tratamento. Depois de seis semanas houve redução dos sintomas e melhora do funcionamento nos dois casos. Ao mesmo tempo, houve redução dos níveis de fator neurotrófico derivado do cérebro, mesmo no caso 2, tratado exclusivamente com psicoterapia. CONCLUSÕES: Esses resultados sugerem que o fator neurotrófico derivado do cérebro está aumentado tanto no transtorno de estresse pós-traumático quanto no transtorno de estresse agudo, de forma oposta às alterações até então descritas nos transtornos do humor.

OBJECTIVE: The aim of this study was to evaluate brain-derived neurotrophic factor levels in two patients, one with posttraumatic stress disorder and one with acute stress disorder, before and after treatment, and to compare those levels to those of healthy controls. METHOD: Brain-derived neurotrophic factor level, Davidson Trauma Scale, Beck Depression Inventory, Global Assessment of Functioning, and Clinical Global Impression were assessed before and after 6 weeks of treatment. RESULTS: Brain-derived neurotrophic factor levels were higher in patients than in matched controls before treatment. After 6 weeks, there was a reduction in symptoms and an improvement in functioning in both cases. At the same time, brain-derived neurotrophic factor levels decreased after treatment, even in case 2, treated with psychotherapy only. CONCLUSIONS: These results suggest that serum levels of brain-derived neurotrophic factor, as opposed to what has been described in mood disorders, are increased in posttraumatic stress disorder as well as in acute stress disorder.
