Quality of life in unipolar and bipolar depression: Are there significant differences?

In the present investigation, we compared the impact of illness on quality of life (QOL) in adult outpatients with unipolar (N = 89) and bipolar (N = 25) depression. While attending a university hospital in southern Brazil, patients completed the WHOs QOL Instrument-Short Version and the Beck Depression Inventory. After analyses, patients with bipolar depression reported significantly lower scores on the psychological QOL domain (p = .013) than patients with unipolar depression. There were no significant differences between the study groups in terms of social and demographic variables, in the other QOL domains assessed (i.e., physical health, social relationships, and environmental), and in the severity of depressive symptoms. In conclusion, our findings suggest that patients with bipolar and unipolar depressions have different QOL profiles, and that this difference is probably independent of the severity of the mood disturbance and might be related to the higher rates of suicide observed in the bipolar population.

A pilot study of clonazepam versus psychodynamic group therapy plus clonazepam in the treatment of generalized social anxiety disorder.

BACKGROUND Both psychodynamic group therapy (PGT) and clonazepam are used as treatment strategies in reducing symptoms of generalized social anxiety disorder (GSAD). However, many individuals remain symptomatic after treatment with PGT or clonazepam. METHOD Fifty-eight adult outpatients with a diagnosis of GSAD according to DSM-IV were randomized to 12 weeks PGT plus clonazepam or clonazepam. The Clinical Global Impression-Improvement (CGI-I) Scale was the primary efficacy measure. Secondary efficacy measures included the Liebowitz Social Anxiety Scale (LSAS) total score, the World Health Organization Instrument to Assess Quality of Life-Brief (WHOQOL-Bref) Scale and the Beck Depression Inventory (BDI). RESULTS CGI-I data from 57 patients (intent-to-treat population) showed that patients who received PGT plus clonazepam presented significantly greater improvement than those who received clonazepam (P=0.033). There were no significant differences between the two groups in the secondary efficacy measures. CONCLUSIONS Our study suggests that the combination of PGT with clonazepam may be a promising strategy for the treatment of GSAD, regarding gains in the global functioning. However the present study failed to detect more specific changes in social anxiety symptomatology between the two groups.

Serum levels of brain-derived neurotrophic factor in acute and posttraumatic stress disorder: a case report study

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.

Does caffeine change the effect of sleep deprivation on moderate to severe depressed patients

INTRODUCTION Sleep deprivation (SD) has been used as an alternative approach to treat major depressive disorder (MDD). Caffeine, due to its stimulating effect, could be an alternative to promote sleep deprivation. However, there are no data about its potential influence on the antidepressive effect of SD. The objective of this study is to assess the effect of caffeine on SD in non-psychotic patients with moderate to severe unipolar depression. METHODS Randomized, double-blind, crossover clinical trial comparing caffeine and placebo in moderate to severe depressed patients who underwent total sleep deprivation (SD). The patients were assessed with items of the Bond-Lader scale, the 6-item Hamilton Depression Rating Scale (HAMD-6), and the Clinical Global Impression (CGI)-Severity/Improvement. RESULTS Twenty patients participated in this study. The patients who consumed caffeine presented the same level of energy before and after sleep deprivation (lethargic-energetic item of the Bond-Lader scale), while the patients in the placebo group had a reduced level of energy after sleep deprivation (p=0.0045). There was no difference between the caffeine and placebo groups in the other items of the Bond-Lader scale. CONCLUSION The combined use of caffeine and SD can be a useful strategy to keep the patient awake without impairing the effect of SD on depressed outpatients. However, further studies involving patients who have responded to SD are needed in order to verify if caffeine also does not interfere with the results in this group.
