Abstract Human T-cell lymphotropic virus type 1 (HTLV-1) has low prevalence rates, but is endemic in some regions of the world. It is usually a chronic asymptomatic infection, but it can be associated with serious neurologic and urinary conditions. Hepatitis C virus (HCV) is broadly spread out worldwide. The majority of these infections have a chronic course that may progress to cirrhosis and hepatocellular carcinoma. Objectives: To compare sociodemographic and mental health (risk behaviors, depression, and suicide) aspects, and quality of life among patients with HCV or HTLV-1. Methods: Observational, comparative and cross-sectional study involving outpatients with HCV or HLTV-1 infection. Sociodemographic characteristics, risk behaviors and quality of life were assessed through the questionnaires Mini International Neuropsychiatric Interview - MINI Plus (depression and suicide) and Medical Outcomes Study 36-Item Short-Form Health Survey (quality of life). Univariate and multivariate statistical analyses (hierarchical logistic regression) were conducted. Results: 143 individuals with HCV and 113 individuals with HTLV-1 infection were included. Males were predominant in the HCV group (68.8%) and females in the HTLV-1 group (71.7%). The frequency of risk behaviors (sexual and drug use) was greater in those with HCV (p < 0.05). A past depressive episode was more common in the HTLV-1 group (p = 0.037). Quality of life was significantly worse in the physical functioning, vitality, mental health, and social functioning domains in those with HTLV-1 (p < 0.05). HTLV-1 infection remained independently associated with worse quality of life in multivariate analysis. Conclusions: Risk behaviors are frequent among those infected with HCV. Additionally, despite HTLV-1 being considered an infection with low morbidity, issues related to mental health (depressive episode) and decreased quality of life are relevant.

Objective: To evaluate the association between personality disorders (PDs) and suicide attempts (SAs) in euthymic patients with type I bipolar disorder (BD). Methods: One-hundred twenty patients with type I BD, with and without history of SA, were evaluated during euthymia. The assessment included a clinical and sociodemographic questionnaire, the Hamilton Depression Rating Scale, the Young Mania Rating Scale, the Barratt Impulsiveness Scale, and Structured Clinical Interviews for DSM-IV Axis I and II Disorders. Logistic regression was employed to determine associations between history of SA and patient characteristics. Results: History of SA was significantly associated with comorbid axis I disorder, rapid cycling, high impulsivity (attentional, motor, non-planning, and total), having any PD, and cluster B and C PDs. Only cluster B PDs, high attentional impulsivity, and lack of paid occupation remained significant after multivariate analysis. Conclusions: Cluster B PDs were significantly associated with SA in patients with type I BD. High attentional impulsivity and lack of gainful employment were also associated with SA, which suggests that some cluster B clinical and social characteristics may exacerbate suicidal behavior in this population. This finding offers alternatives for new therapeutic interventions.

Objectives: To describe the onset pattern, frequency, and severity of the signs and symptoms of the prodrome of the first hypomanic/manic episode and first depressive episode of bipolar disorder (BD) and to investigate the influence of a history of childhood maltreatment on the expression of prodromal symptoms. Methods: Using a semi-structured interview, the Bipolar Prodrome Symptom Scale-Retrospective (BPSS-R), information regarding prodromal symptoms was assessed from patients with a DSM-IV diagnosis of BD. History of childhood maltreatment was evaluated using the Childhood Trauma Questionnaire (CTQ). Results: Forty-three individuals with stable BD were included. On average, the prodrome of mania lasted 35.8±68.7 months and was predominantly subacute or insidious, with rare acute presentations. The prodrome of depression lasted 16.6±23.3 months and was also predominantly subacute or insidious, with few acute presentations. The prodromal symptoms most frequently reported prior to the first hypomanic or manic episode were mood lability, depressive mood, and impatience. A history of childhood abuse and neglect was reported by 81.4% of participants. Presence of childhood maltreatment was positively associated with prodromal symptoms, including social withdrawal, decreased functioning, and anhedonia. Conclusions: This study provides evidence of a long-lasting, symptomatic prodrome prior to first hypomanic/manic and depressive episode in BD and suggests that a history of childhood maltreatment influences the manifestations of this prodrome.
