Spontaneous treatment discontinuation in panic disorder patients treated with antidepressants.

Objective: We examined the relationships between long-term treatment response, side-effects and drug discontinuation in panic disorder (PD)-agoraphobia.

Method: A total of 326 patients were naturalistically treated with antidepressants and followed for a period of 3 years. All patients were evaluated by means of the Panic Disorder/Agoraphobia Interview and the Longitudinal Interview Follow-up Examination (LIFE-UP).

Obsessive-compulsive bipolar comorbidity: focus on children and adolescents.

Background: Growing evidence documents the frequent co-morbidity between Obsessive Compulsive Disorder (OCD) and Bipolar Disorder (BP) in adults. The aim of the present study is to explore some clinical aspects of this interface in children and adolescents, as it appears in a setting of routine clinical practice.

Method: The sample comprised 102 consecutively referred children and adolescents, both inpatients and outpatients, with BP, OCD or co-morbid BP-OCD during a 3-year period.

Cyclothymic OCD: a distinct form?

Background: Clinical research on the comorbidity of obsessive compulsive disorder (OCD) and other anxiety disorders has largely focused on depression. However in practice, resistant or severe OCD patients not infrequently suffer from a masked or hidden comorbid bipolar disorder.

Method: The rate of bipolar comorbidity in OCD was systematically explored among 453 members of the French Association of patients suffering from OCD (AFTOC) as well as a psychiatric sample of OCD out-patients (n=175).

Externalizing disorders in consecutively referred children and adolescents with bipolar disorder.

We describe a consecutive clinical sample of children and adolescents with bipolar disorder (BD), in order to define the pattern of comorbid externalizing disorders and to explore the possible influence of such a comorbidity on their cross-sectional and longitudinal clinical characteristics. The sample consisted of 59 bipolar patients: 35 males and 24 females, with a mean age 14.6 +/- 3 years (range, 7 to 18 years), diagnosed as either type I or II according to DSM-IV.

Phenomenology and comorbidity of dysthymic disorder in 100 consecutively referred children and adolescents: beyond DSM-IV.

Objective: Diagnostic criteria and nosological boundaries of juvenile dysthymic disorder (DD) are under-researched. Two different sets of diagnostic criteria are still discussed in the DSM-IV, the first giving major weight to somatic and vegetative symptoms and the second, included in the appendix, to more affective and cognitive symptoms. The aim of this study was to describe prototypical symptomatology and comorbidity of DD, according to DSM-IV criteria, in a consecutive series of referred children and adolescents, as a function of age and sex.

Temperament in adolescents with anxiety and depressive disorders and in their families.

Aim of this study was to investigate whether specific temperamental features were associated with anxiety and depressive disorders in adolescents, in their siblings and in their parents. Thirty adolescents with Anxiety disorders and 25 with both Anxiety and Depressive disorders were compared to 25 adolescents with learning disorders and to 28 normal subjects. Temperament in subjects and relatives was assessed by their parents with the EAS questionnaire.

Obsessive-compulsive-bipolar comorbidity: a systematic exploration of clinical features and treatment outcome.

Background: Notwithstanding the emerging literature on comorbidity between obsessive-compulsive disorder (OCD) and bipolar disorder, relatively few systematic data exist on the clinical characteristics of this interface and its treatment. The aim of the present study is to address this challenge as it appears in a setting of routine clinical practice.

Method: The sample comprised 68 patients with comorbid DSM-IV diagnoses of OCD and major depressive episode admitted and treated at the day-hospital in the Department of Psychiatry at the University of Pisa (Pisa, Italy) during a 3-year period (January 1995-December 1998).

The role of cyclothymia in atypical depression: toward a data-based reconceptualization of the borderline-bipolar II connection.

Objective: Recent data, including our own, indicate significant overlap between atypical depression and bipolar II. Furthermore, the affective fluctuations of patients with these disorders are difficult to separate, on clinical grounds, from cyclothymic temperamental and borderline personality disorders. The present analyses are part of an ongoing Pisa-San Diego investigation to examine whether interpersonal sensitivity, mood reactivity and cyclothymic mood swings constitute a common diathesis underlying the atypical depression-bipolar II-borderline personality constructs.

The soft bipolar spectrum redefined: focus on the cyclothymic, anxious-sensitive, impulse-dyscontrol, and binge-eating connection in bipolar II and related conditions.

The bipolar II spectrum represents the most common phenotype of bipolarity. Numerous studies indicate that in clinical settings this soft spectrum might be as common--if not more common than--major depressive disorders. The proportion of depressive patients who can be classified as bipolar II further increases if the 4-day threshold for hypomania proposed by the DSM-IV is reconsidered.

Effectiveness of adjunctive gabapentin in resistant bipolar disorder: is it due to anxious-alcohol abuse comorbidity?

We evaluated effectiveness and predictors of response of gabapentin (GBP) as adjunctive treatment in a sample of 43 subjects with DSM-III-R bipolar disorder who were resistant to standard mood stabilizers. Diagnostic evaluation was performed by means of the Semistructured Interview for Mood Disorder. Clinical evaluation was performed at the beginning and end of the observation period by means of the Hamilton Rating Scale for Depression (HAM-D), the Young Mania Rating Scale, and the Clinical Global Impression Scale.

Open-label evaluation of venlafaxine sustained release in outpatients with generalized anxiety disorder with comorbid major depression or dysthymia: effectiveness, tolerability and predictors of response.

In a setting of routine clinical practice, 32 outpatients with generalized anxiety disorder (GAD) and major depression (MD) (n = 21) or dysthymia (n = 11), according to DSM-IV criteria, were consecutively treated with flexible dosages of sustained-release venlafaxine (SR-VF) for at least 8 weeks. In a 16-week follow-up, SR-VF daily dose could be modified on the basis of the therapeutic response and of the side effect profile. Symptomatological modifications were explored by means of the Clinical Global Impression (CGI) scale, Hamilton Rating Scale for Depression (HAM-D), and Hamilton Anxiety Scale (HAM-A).

[Cyclothymic obsessive-compulsive disorder. Clinical characteristics of a neglected and under-recognized entity].

Objective: Clinical research is largely focused on depressive comorbidity in obsessional compulsive disorder (OCD). However some recent publications have suggested that bipolar comorbidity occurs in authentic OCD and its presence has a differential impact on the clinical picture and course of OCD.

Method: Recent data from the collaborative survey conducted with AFTOC (French Association of patients suffering from OCD) have revealed a high rate of bipolar comorbidity in OCD: 30% for hypomania and 50% for cyclothymia.

Alcohol abuse in social phobic patients: is there a bipolar connection?

Background: Epidemiological and clinical studies have reported the frequent co-occurrence of social phobia (SP) and alcohol use disorders. Patients with SP often use alcohol to cope with the social situations they fear, and to lessen anticipatory anxiety, behavioral inhibition, and phobic avoidance. We investigated whether the presence of lifetime comorbidity with alcohol abuse was associated with significant differences as regards demographic and clinical features, family history and pattern of comorbidity in a large clinical sample of SP outpatients.

The temporal relationship between anxiety disorders and (hypo)mania: a retrospective examination of 63 panic, social phobic and obsessive-compulsive patients with comorbid bipolar disorder.

Background: The relationship between anxiety and depressive disorders has been conventionally limited to unipolar depression. Recent studies from both clinical and epidemiologic samples have revealed intriguing associations between anxiety and bipolar (mainly bipolar II) disorders. The present report examines the temporal sequence of hypomania to panic (PD), obsessive-compulsive (OCD) and social phobic (SP) disorders.

Clinical characterization of depressive mixed state in bipolar-I patients: Pisa-San Diego collaboration.

Background: Although mixed states were classically described as various concomitant admixtures of depression and mania, the official current definitions in both DSM-IV and ICD-10 tend to restrict the concept to manic patients with full syndromal depression. Recent research has actually shown that mania with few depressive symptoms constitutes the most prevalent clinical presentation of mixed or dysphoric mania. Major depressive patients with few concomitant manic symptoms are not officially recognized within the current nosology.

Reboxetine, a selective norepinephrine reuptake inhibitor, is an effective and well-tolerated treatment for panic disorder.

Background: Tricyclic antidepressants and selective serotonin reuptake inhibitors (SSRIs) as well as benzodiazepines have been shown to be effective for the treatment of panic disorder. The introduction of SSRIs has enabled a greater understanding of the role of serotonin in the etiology of panic disorder; however, the role of norepinephrine has been more challenging to ascertain. The aim of this study was to determine the efficacy and tolerability of reboxetine, a novel selective norepinephrine reuptake inhibitor, in patients with panic disorder with and without agoraphobia.

Anxiety disorders in children and adolescents with bipolar disorder: a neglected comorbidity.

Objective: We describe a consecutive clinical sample of children and adolescents with bipolar disorder to define the pattern of comorbid anxiety and externalizing disorders (attention-deficit hyperactivity disorder [ADHD] and conduct disorder [CD]) and to explore the possible influence of such a comorbidity on their cross-sectional and longitudinal clinical characteristics.

Methods: The sample comprised 43 outpatients, 26 boys and 17 girls, (mean age 14.9 years, SD 3.

Putative clinical subtypes of social phobia: a factor-analytical study.

Objective: To examine symptomatological subtypes of social phobia (SP) and their relationships with a number of feared situations and avoidant personality disorder (APD).

Method: In 153 out-patients with SP according to DSM-III-R criteria, clinical subtypes were investigated by means of principal component factor analysis of the Liebowitz Social Anxiety Scale (LSAS). We compared the various SP subtypes on the basis of the highest Z-scores obtained on each LSAS factor.

Bipolar II and unipolar comorbidity in 153 outpatients with social phobia.

Previous studies on social phobia (SP) have focused largely on comorbidity between SP and major depression. Less attention has been devoted to the comorbidity between SP and bipolar disorder. In this retrospective study, we investigated family history, lifetime comorbidity, and demographic and clinical characteristics among 153 outpatients who met DSM-III-R diagnostic criteria for SP.

Adjunctive dopamine agonists in treatment-resistant bipolar II depression: an open case series.

Objective: Previous studies and case observations have suggested that dopamine agonists (DAAs) such as pramipexole (PPX) and ropinirole (RPN) might be effective for major depression, but their adjunctive use in treatment-resistant bipolar II depression has not yet been specifically addressed.

Method: A chart review was conducted on 18 patients with a DSM-III-R bipolar NOS (Bipolar II) major depressive episode who were admitted to the day-hospital of the Department of Psychiatry at the University of Pisa. DAAs were added to ongoing treatments with conventional antidepressants and mood stabilizers to which patients had no responded after a period of at least 8 weeks.

Paroxetine in child and adolescent outpatients with panic disorder.

Paroxetine has repeatedly been shown to be effective in the treatment of panic disorder (PD) in adults, and, according to previous case observations, it may be useful in treating children and adolescents with PD as well. This preliminary naturalistic study examines effectiveness and safety of paroxetine in the treatment of children and adolescents with PD. A chart review was conducted on 18 patients with Diagnostic and Statistical Manual of Mental Disorders PD admitted to the Division of Child Neurology and Psychiatry and to the Department of Psychiatry at the University of Pisa.

Is mood-incongruent manic psychosis a distinct subtype?

Background: Despite several research reports on incongruent psychotic features in mania, whether such features define a distinct disorder is unsettled.

Method: One hundred and fifty-five inpatients with mania according to DSM-III-R were systematically evaluated in order to collect demographic and clinical information. The symptomatological evaluation was conducted by means of the Comprehensive Psychopathological Rating Scale (CPRS) and the Scale for the Assessment of Positive Symptoms (SAPS).

The contrasting influence of depressive and hyperthymic temperaments on psychometrically derived manic subtypes.

The present investigation focused on symptomatological subtypes of mania and their relationships with affective temperaments and other clinical features of bipolar disorder. In 153 inpatients with mania diagnosed according to DSM-III-R, symptomatological subtypes have been investigated by means of principal component factor analysis of 18 selected items of the Comprehensive Psychopathological Rating Scale (CPRS). We compared other clinical features, depressive and hyperthymic temperamental attributes, and first degree-family history for mood disorders among the various manic subtypes on the basis of the highest z-scores obtained on each CPRS factor (dominant CPRS factor groups).

A prospective naturalistic study of 326 panic-agoraphobic patients treated with antidepressants.

Objective: How far the results of randomized controlled studies apply to everyday care cannot be judged without regular measurements of outcomes in daily practice. We report on systematic data from a 3-year naturalistic prospective study on panic disorder-agoraphobic (PDA) patients treated with antidepressants in a setting of routine clinical practice. Our aim is to describe the evolution of PDA in relation to the treatments employed, and to explore demographic and clinical characteristics that might be predictive of outcome.

Polarity of the first episode, clinical characteristics, and course of manic depressive illness: a systematic retrospective investigation of 320 bipolar I patients.

In 320 patients with established bipolar I disorder, we examined the past course on the basis of polarity at onset (depressive, mixed, and manic). Despite the obvious limitations of retrospective methodology, information on course parameters in a large sample of affective disorders is most practically obtained by such methodology. We believe that our systematic interview of patients and their relatives--as well as the systematic study of their records--minimized potential biases.
