ABSTRACT
Objective: To estimate the prevalence of major depressive episode (MDE) in patients with presumptive pulmonary tuberculosis (pre-PTB, defined by cough lasting ≥ 3 weeks) and compare it between patients with pulmonary tuberculosis (PTB) and without PTB. Methods: Patients with pre-PTB (n=260) were screened for depression using the Patient Health Questionnaire (PHQ-9). Those individuals with scores ≥ 10 were subsequently assessed with the depression module of the Mini International Neuropsychiatric Interview (MINI-Plus) to confirm diagnosis. Associations of categorical variables with PTB and MDE were calculated using the chi-square test and OR. Results: PTB was confirmed in 98 patients (37.7%). A high proportion of both groups (active PTB and no PTB) screened positive for depression (60.2 vs. 62.1%, respectively). Among 159 patients who screened positive for depression, a subset of 97 (61.0%) were further evaluated with the MINI-Plus; current MDE was confirmed in 54.6% (53/97). On univariate and multivariate analysis, female sex was the only factor associated with the diagnosis of current MDE (p = 0.04). Conclusion: The prevalence of MDE was high among individuals with prolonged respiratory symptoms, independent of PTB diagnosis. This is consistent with other studies of depression in primary care in Brazil.

OBJECTIVE: This article reviews the evidence for the major risk factors associated with suicidal behavior in bipolar disorder. METHOD: Review of the literature studies on bipolar disorder, suicidal behavior and suicidal ideation. RESULTS: Bipolar disorder is strongly associated with suicide ideation and suicide attempts. In clinical samples between 14-59 percent of the patients have suicide ideation and 25-56 percent present at least one suicide attempt during lifetime. Approximately 15 percent to 19 percent of patients with bipolar disorder die from suicide. The causes of suicidal behavior are multiple and complex. Some strong predictors of suicidal behavior have emerged in the literature such as current mood state, severity of depression, anxiety, aggressiveness, hostility, hopelessness, comorbidity with others Axis I and Axis II disorders, lifetime history of mixed states, and history of physical or sexual abuse. CONCLUSION: Bipolar disorder is the psychiatric condition associated with highest lifetime risk for suicide attempts and suicide completion. Thus it is important to clinicians to understand the major risk factors for suicidal behavior in order to choose better strategies to deal with this complex behavior.
OBJETIVO: O artigo revisa as evidências relacionadas aos principais fatores de risco associados ao comportamento suicida no transtorno bipolar. MÉTODO: Revisão de artigos da literatura em transtorno bipolar, tentativa de suicídio e ideação suicida. RESULTADOS: O transtorno bipolar está fortemente associado à presença de ideação suicida e a tentativas de suicídio. Em amostras clínicas, entre 14 por cento e 59 por cento dos pacientes apresentam ideação suicida e entre 25 por cento e 56 por cento têm pelo menos uma tentativa de suicídio ao longo da vida. Aproximadamente 15 por cento a 19 por cento dos pacientes com transtorno afetivo bipolar morrem por suicídio. As causas do comportamento suicida são múltiplas e complexas. Alguns preditores de comportamento suicida vêm sendo demonstrados consistentemente na literatura, tais como estado de humor atual, gravidade da depressão, ansiedade, agressividade, hostilidade, presença de comorbidades com outros transtornos do eixo I e eixo II, presença de estados mistos ao longo do curso da doença e história de abuso físico ou sexual. CONCLUSÃO: O transtorno bipolar é o transtorno psiquiátrico com maior risco ao longo da vida para tentativas de suicídio e suicídio completo. Sendo assim é importante para o clínico identificar os principais fatores de risco para comportamento suicida visando a escolha das melhores estratégias para lidar com esse comportamento complexo.
