Double-blind comparison of 30 and 60 mg tranylcypromine daily in patients with panic disorder comorbid with social anxiety disorder.

Our objective was to explore the dose-response relationship in patients with panic disorder and social anxiety disorder comorbidity (DSM-IV). After 1 week of no-drug washout, 36 such patients were assigned to a double-blind controlled comparison of the effects of 30 mg and 60 mg of tranylcypromine, and were followed up for 12 weeks. The main instrument used to measure the number of panic attacks was the Sheehan Panic and Anticipatory Anxiety Scale. The primary outcome measure for social anxiety disorder symptoms was the mean change from baseline in the Liebowitz Social Anxiety Scale (LSAS). After 12 weeks of treatment, panic attacks were reduced 69.6% from baseline in the 30-mg group (n=19) compared with a 74.8% reduction in the 60-mg group (n=17). Twelve patients (70.6%) of the higher dose group and 14 patients (68.4%) of the lower dose were completely free of panic attacks. There was no difference in efficacy between the tranylcypromine groups in the panic disorder symptoms. The 60-mg dose was more efficacious as measured by the LSAS scores, showing a significant difference in relation to the lower group. Mean change from baseline in LSAS total score (mean+/-SD) for 30-mg group was 17.9+/-14.7 and for the 60-mg group was 35.0+/-14.8. The social anxiety symptom scale showed a two-fold greater change with the 60-mg dose, and the 30-mg dose group could be considered the equivalent of a placebo control group. Tranylcypromine--60 mg daily--was found effective in the treatment of panic disorder and social anxiety disorder comorbidity.

Demographic and clinical features of panic disorder comorbid with bipolar I disorder: a 3-year retrospective study.

BACKGROUND: Mood disorders are considered related to anxiety disorders and their association may determine clinical course and prognosis. We aimed to describe with retrospective methodology the demographic, clinical, and treatment features in a group of panic disorder comorbid with bipolar I disorder (PD-BI) patients who were been treated for at least 3 year-period and compare them with bipolar I (BI) patients who were treated during the same period. METHOD: We compared the demographic and clinical data of 26 PD-BI, 28 BI, and 25 panic disorder (PD) outpatients without history of comorbidity with mood disorder were diagnosed and treated for at least 3 years in the Federal University of Rio de Janeiro. RESULTS: PD group have a higher educational level, are more married, and are more economically active. In the PD-BI and BI patients the disorders started earlier. They also turn out to have an equivalent pattern in the presence of drug abuse episodes, moderate or severe depressive episodes, psychotic episodes, suicide attempts, maniac episodes, mixed episodes, use of fewer days of antidepressants and benzodiazepines, and use of more days of antipsychotics and mood stabilizers. The PD-BI and the BI groups had a higher frequency of depressive episodes and psychotic episodes. LIMITATIONS: It is a retrospective data description based on a naturalistic treatment. The sample has a small size and the some data could be different in a large sample. CONCLUSION: PD-BI patients have demographic, clinical and therapeutic features similar to BI and the data support its validation as a special severe bipolar I disorder subgroup.

Demographic and clinical features of schizoaffective (schizobipolar) disorder--a 5-year retrospective study. Support for a bipolar spectrum disorder.

BACKGROUND: Schizobipolar disorder is considered related to both schizophrenia and bipolar disorder. We aimed to describe with retrospective methodology the demographic, clinical, and treatment features in a group of schizobipolar disorder patients who have been treated for at least a 5-year period and compare them with bipolar I and schizophrenic patients who were treated during the same period. METHOD: We compared the demographic and clinical data of 61 schizobipolar, 57 bipolar I, and 55 schizophrenic outpatients who were diagnosed and treated for at least 5 years in the outpatient clinic in the Federal University of Rio de Janeiro. RESULTS: The schizobipolar disorder patients had a profile similar to the bipolar I patients but are significantly different from schizophrenic patients in educational level, marital status, occupation, drug and alcohol abuse episodes, presence of depressive, mixed and maniac episodes, family history of bipolar I and mood disorders, and use of medications. Only the age of onset, suicide attempts, and family history of suicide are not significantly different among the groups. The schizophrenic patients used antipsychotics for more days and the schizobipolar and bipolar I used more antidepressants and mood stabilizers. 37 (60.6%) schizobipolar patients had their diagnosis changed to bipolar disorder by their physician in different periods during the period studied. LIMITATIONS: It is a retrospective data description based on a naturalistic treatment. The family history was collected from the patient and whenever possible from one first-degree relative. CONCLUSION: Schizobipolar disorder patients have demographic, clinical and therapeutic features similar to bipolar I patients and data support its definite inclusion in the bipolar spectrum group.
