Can psychopharmacological treatment change personality traits in patients with panic disorder? / O tratamento psicofarmacológico pode mudar traços de personalidade em pacientes com transtorno do pânico?

OBJECTIVE: The aim of this study was to evaluate the effects that a particular psychopharmacological treatment has on personality patterns in patients with panic disorder. METHOD: Forty-seven patients with panic disorder and 40 controls were included in the study. The Mini International Neuropsychiatric Interview and Minnesota Multiphasic Personality Inventory were used to assess Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnoses and personality traits, respectively. Patients were treated with sertraline for 16 weeks. RESULTS: There was a significant decrease in the score on 8 of the 10 Minnesota Multiphasic Personality Inventory scales. In addition, neurotic triad and psychasthenia personality scores were higher among panic disorder patients, even during the posttreatment asymptomatic phase, than among controls. CONCLUSION: In the asymptomatic phase of the disease, panic disorder patients present a particular neurotic/anxious personality pattern. This pattern, although altered in the presence of acute symptoms, could be a focus of research.

OBJETIVO: O objetivo do estudo foi avaliar os efeitos do tratamento psicofarmacológico nos padrões de personalidade em pacientes com transtorno do pânico. MÉTODO: Quarenta e sete pacientes com transtorno do pânico e 40 controles foram incluídos no estudo. O Mini International Neuropsychiatric Interview e o Inventário Multifásico Minnesota de Personalidade foram usados para avaliar os diagnósticos do Manual Diagnóstico e Estatístico de Doenças Mentais - Quarta Edição e os traços de personalidade, respectivamente. Os pacientes foram tratados com sertralina por 16 semanas. RESULTADOS: Houve uma diminuição significativa nos escores de 8 das 10 escalas do Inventário Multifásico Minnesota de Personalidade. Adicionalmente, os pacientes com transtorno do pânico apresentaram maiores escores de personalidade da tríade neurótica e de psicastenia quando comparados aos controles, mesmo após o tratamento na fase assintomática. CONCLUSÃO: Pacientes com transtorno do pânico apresentam um padrão de personalidade neurótico/ansioso na fase assintomática da doença que, mesmo que influenciado pela presença de sintomas agudos, pode ser foco de pesquisa.

Harm avoidance and self-directedness as essential features of panic disorder patients.

OBJECTIVE: The purpose of the study is to compare the personality traits assessed with the Temperament and Character Inventory (TCI) between patients with panic disorder (PD) and a control group in a Brazilian sample. METHODS: One hundred thirty-five patients with PD paired according to sex and age with 135 controls without any psychiatric disorders were assessed with the Mini International Neuropsychiatric Interview (MINI), a structured interview. Temperament and character were assessed with the TCI. RESULTS: Consistently, patients with PD presented higher scores on the harm avoidance (HA) temperament scale (23.20 +/- 5.41 vs 15.21 +/- 4.92; P < .001) and lower scores on the self-directedness (SD) (27.81 +/- 7.25 vs 35.16 +/- 5.47; P < .001) if compared to the control group and has been associated independently from other TCI scales and confounders with PD. The multivariate logistic model containing HA and SD explains 38.6% to 51.4% of the differences between PD and controls. CONCLUSIONS: Harm avoidance could be a good candidate to be heritable because it appears to be a consistent finding across current literature in anxious and depressed patients independent of their cultural context. Also, SD seems to be a key character characteristic of PD patients. The dimensional assessment is an interesting alternative for understanding the relationship between the psychobiologic bases of temperament and character and is highly related to the development of psychiatric syndromes.

Lack of association between the serotonin transporter promoter polymorphism (5-HTTLPR) and personality traits in asymptomatic patients with panic disorder.

The serotonin transporter promoter polymorphism (5-HTTLPR) has been investigated regarding its association with neuroticism, which, in its turn, is a personality dimension often found in patients with panic disorder (PD). It has been recently evidenced that the long 5-HTTLPR polymorphism has a genetic variation (Lg), which is related to its lower expression. The objective of this study was to assess the association between the 5-HTTLPR polymorphism in the triallelic system and the neurotic personality traits in patients in PD remission. Sixty-seven Caucasian patients with PD diagnosis according to the DSM-IV-TR assessed with the MINI (mini international neuropsychiatric interview) were included. The MMPI (Minnesota multiphasic personality inventory) was used to assess the personality. The remission of PD symptoms was defined as CGI (clinical global impression)

Trauma and defense style as response predictors of pharmacological treatment in panic patients.

BACKGROUND: As panic disorder (PD) has a chronic course, it is important to identify predictors that might be related to non-remission. The aim of this study is to verify whether history of trauma and defense style are predictors to pharmacological treatment response in PD patients. METHOD: The sample was composed by 47 PD patients according to DSM-IV who were treated with sertraline for 16 weeks. Evaluations were assessed by the C.G.I. (Clinical Global Impression), the Hamilton-Anxiety Scale, the Hamilton-Depression Scale, the Panic Inventory and the DSQ-40 (Defense Style Questionnaire) at baseline and after treatment. RESULTS: Full remission was observed in 61.7% of the sample. The predictors significantly associated with non-remission were: severity of PD (p=0.012), age of onset (p=0.02) and immature defenses (p=0.032). In addition, the history of trauma was associated with early onset of PD (p=0.043). CONCLUSION: Panic patients had as predictors of worse response to pharmacological treatment the early onset and the severity of PD symptoms as well as the use of immature defenses at baseline. This finding corroborates the relevance of the evaluation of factors that might affect the response so as to enable the development of appropriate treatment for each patient.
