FUNDAMENTO: Tem-se observado que a depressão é preditora de reinternação e mortalidade na insuficiência cardíaca. O hormônio da paratireoide é um biomarcador novo e promissor que pode predizer a internação, a capacidade funcional e a mortalidade na insuficiência cardíaca. OBJETIVO: Nosso objetivo foi investigar a associação da depressão aos níveis séricos de hormônio da paratireoide em pacientes com insuficiência cardíaca sistólica. MÉTODOS: Cem pacientes ambulatoriais consecutivos com IC sistólica com fração de ejeção do ventrículo esquerdo < 40% foram examinados prospectivamente. Todos os pacientes foram submetidos a exames laboratoriais, incluindo análises de peptídeo natriurético cerebral e de hormônio da tireoide. Os pacientes foram convidados a completar o Inventário de Depressão de Beck-II. RESULTADOS: Cinquenta e um pacientes (51%) apresentavam escore de BDI ruim (escore de BDI > 18). Esses pacientes apresentavam níveis de hormônio da paratireoide significativamente mais elevados em comparação com aqueles com bons escores de BDI (133 ± 46 pg/ml versus 71 ± 26 pg/ml, p < 0,001). No modelo de regressão logística multivariada, constatou-se que o nível do hormônio da tireoide (razão de chances (OR) = 1.035, p = 0,003), fração de ejeção do ventrículo esquerdo (OR = 0,854, p = 0,004), classe funcional III / IV (OR = 28,022, p = 0,005), C-reactive protein (CRP) (OR = 1,088, p = 0,020) e presença de edema pré-tibial (OR = 12,341, p = 0,033) constituíam preditores independentes de depressão moderada a importante após o ajuste de outros possíveis fatores de confusão. CONCLUSÃO: Pacientes com insuficiência cardíaca sistólica com depressão moderada a importante apresentavam níveis séricos elevados de hormônio da tireoide e CRP, capacidade funcional ruim e fração de ejeção do ventrículo esquerdo mais baixa. A associação da depressão com esses parâmetros pode explicar a contribuição da depressão para a internação e a mortalidade na insuficiência cardíaca.BACKGROUND: Depression has been found to be a predictor of rehospitalization and mortality in heart failure (HF). Parathyroid hormone (PTH) is a novel promising biomarker that can predict hospitalization, functional status and mortality in HF. OBJECTIVE: We aimed to investigate the association of depression with serum PTH levels in patients with systolic HF. METHODS: A total of consecutive 100 outpatients with systolic HF having left ventricular ejection fraction (LVEF) < 40%, were prospectively studied. All patients underwent laboratory tests, including brain natriuretic peptide (BNP) and PTH analyses. The patients were asked to complete the Beck Depression Inventory- II (BDI). RESULTS: Fifty-one patients (51%) were shown to have poor BDI score (BDIS > 18). Patients with poor BDI score had significantly higher PTH levels compared to those with good BDIS (133 ± 46 pg/ml vs. 71 ± 26 pg/ml, p < 0.001). In multivariable logistic regression model, PTH level (Odds ratio (OR) = 1.035, p = 0.003), LVEF (OR = 0.854, p = 0.004), NYHA functional class III/IV (OR = 28.022, p = 0.005), C-reactive protein (CRP) (OR = 1.088, p = 0.020), and presence of pretibial edema (OR = 12.341, p = 0.033) were found to be independent predictors of moderate to severe depression after adjustment of other potential confounders. CONCLUSION: Systolic HF patients with moderate to severe depression had higher serum levels of PTH and CRP, poor functional status and lower LVEF. The association of depression with such parameters might explain the contribution of depression to hospitalization and mortality in HF.

Objective: The aim of this study was to detect the frequency of suicide attempts as well as psychological disorders for the individuals that attempt to commit suicide in the province of Sivas and clarify the relation between suicide attempts and the relevant characteristics. Method: The socio-demographic information was collected during the clinical interview. Structured clinical interview for axis I disorders based on DSM-IV (Structured Clinical Interview for DSM-IV, SCID-I) and structured clinical interview for personality disorders based on DSM-III-R (Structured Clinical Interview for DSM-III-R, SCID-II) were administered, consecutively. Results: Majority of the suicide attempters were women, at the 18-29 age group, people with low level of education, housewives and unemployed people of low socio-economical status whose parents also have a low education profile and people who belong to the core family structure. The most common method of suicide attempts was taking high doses of drugs. The most frequent reported reason for suicide was family disputes (33%). 61% of the cases were identified as having an axis I disorder and 58% were identified as having an axis II disorder. The most frequent axis I diagnosis was major depressive disorder and the most frequent axis II diagnosis was borderline personality disorder. Mood disorders were more common among married people, people at age 30 or older, people who have a history of a psycho-social stress factor before attempt and among those who have previous suicide attempts. Cluster B personality disorders were more common among people with dysfunctional family relationships, split family, alcohol abuse and previous suicide attempts. Conclusions: In-depth assessment for cases with depressive disorder and borderline personality disorder should include inquiry about previous suicide attempts and these cases should receive appropriate treatment. It should be kept in mind that the probability of suicide attempts is high for these cases. [ABSTRACT FROM AUTHOR]
