Psychoeducation in bipolar patients with comorbid personality disorders

BACKGROUND: The co-occurrence of personality and bipolar disorders is quite common. Bipolar patients with personality disorders have been described as having poorer outcome than 'pure' bipolar patients. However, from a combined-approach point of view, a little has been done to improve the course of these patients. Psychoeducation has shown its efficacy in the prevention of relapses in the bipolar population but, to date, no data is available on its efficacy in the management of bipolar patients with personality disorders. METHOD: The present study shows a subanalysis from a single-blind randomized prospective clinical trial on the efficacy of group psychoeducation in bipolar I patients. Bipolar patients fulfilling DSM-IV criteria for any personality disorder were randomized to either psychoeducational treatment or a non-structured intervention. There were 22 patients in the control group and 15 in the psychoeducation group. All patients received naturalistic pharmacological treatment as well. The follow-up phase comprised 2 years where all patients continued receiving naturalistic treatment without psychological intervention and were assessed monthly for several outcome measures. RESULTS: At the end of the follow-up phase (2 years), a 100% of control group patients fulfilled criteria for recurrence versus a 67% in the psychoeducation group (p < 0.005). Patients included in the psychoeducation group had a higher time-to-relapse and a significantly lower mean number of total, manic and depressive relapses. No significant differences regarding the number of patients who required hospitalization were found but the mean duration of days spent in the hospitalization room was significantly higher for the patients included in the control group. CONCLUSION: Psychoeducation may be a useful intervention for bipolar patients with comorbid personality disorders. Further studies should address the efficacy of specifically tailored interventions for this common type of patients.     

Psychosocial outcome in bipolar I patients with a personality disorder

This study examined whether comorbid personality disorders and other clinical factors were predictive of functional morbidity in bipolar I disorder. Fifty-one participants with a diagnosis of bipolar I were assessed for personality disorders and administered measures of symptomatic and functional outcomes approximately 1 year after a psychiatric hospitalization. Forty-five percent of the sample met criteria for at least one personality disorder, and patients with a personality disorder reported higher levels of residual symptoms at the time of assessment. Two thirds of participants displayed compromised functional outcomes. The three outcome domains examined (i.e., occupational, residential, social/leisure) were related to a range of clinical characteristics, and for all three, either the presence of a personality disorder diagnosis or maladaptive trait scores was associated with impaired functioning. These relationships, however, were not independent of mood symptoms according to multivariate analysis. Residual depression predicted poorer residential and social/leisure outcomes independent of personality disorders or maladaptive traits.     

Sympathetic reactivity in agoraphobic patients with and without personality disorders

OBJECTIVE: To compare sympathetic activity in agoraphobic patients with and without personality disorders before and after 11 weeks inpatient treatment. METHODS: Agoraphobic patients (n=38), 84% with panic disorder and 47% with personality disorders underwent cold pressure test (CPT), mental stress test (MST), and a specific anxiety test (SAT). Psychological assessments were done by the Bodily Sensations Questionnaire (BSQ), the Agoraphobic Cognitions Questionnaire (ACQ), Spielberger STAI-1 and -2, and a Stress Test Anxiety (STA) questionnaire. Sympathetic activity was measured by blood pressure, heart rate, epinephrine, and norepinephrine. RESULTS: The sympathetic activity did not differ significantly between patient groups, and the reactivity to stress was very low. The sympathetic reactivity remained unchanged after treatment, whereas psychiatric symptoms decreased. Correlations between sympathetic activity and psychological distress were not significant. CONCLUSION: Interpretation of bodily signals seems to be more important than the actual sympathetic activity in agoraphobic patients.     

Sleep disorders in patients with personality disorders

63 patients with personality disorders have been hospitalized in a Sleep Disorder Clinic. Sleep disorders usually started during childhood, disappeared ant the reappeared around the age of 25. The polysomnographic data do not show a specific profile. Most of the patients were of the schizotypal or the borderline type. Therapeutic guidelines are presented.     

Frequency of comorbid personality disorders in bipolar and unipolar affective disorders

One expression of the complex relationship between personality and affective disorder is the comorbidity of personality disorders (PDs) with affective disorders. In a sample of 117 patients with unipolar and 60 with bipolar affective disorders, we assessed DSM-III-R PDs with the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II) and compared them with personality factors as obtained by the five-factor model (FFM-NEO Five-Factor Inventory). Fifty-one percent of the unipolar and 38% of the bipolar disorders fulfilled criteria for a comorbid PD. The three most frequent PDs were obsessive-compulsive PD, borderline PD, and narcissistic (bipolar) or avoidant (unipolar) PD. Cluster C PDs and especially avoidant PD occurred significantly more frequently in unipolar than in bipolar patients, while narcissistic PD occurred significantly more often in bipolar than in unipolar patients. The FFM results supported the validity of our PD diagnoses. In a logistic regression analysis, higher depression score at the time of the SCID-II interview and shorter duration of the illness were weakly related to a higher frequency of PDs. Our results indicate that PDs are frequent in affective disorders and that there are subtle differences between unipolar and bipolar patients concerning such comorbid disorders.     

DSM-III-R personality disorders in patients with eating disorders

The authors conducted a systematic examination of DSM-III-R personality disorders among 35 patients with eating disorders. Fifty-seven percent of the patients met the criteria for at least one axis II diagnosis; borderline, self-defeating, and avoidant were the most frequently assigned personality disorders. Forty percent of the patients were given two or more diagnoses, and 17% of the patients met criteria for five to seven diagnoses. No differences were found between patients with anorexia nervosa, anorexia and bulimia nervosa, and bulimia nervosa in the distribution of diagnoses or the frequency with which individual criteria (traits) were assigned.     

Prophylaxis latency and outcome in bipolar disorders.

OBJECTIVE: To analyze new and reviewed findings to evaluate relations between treatment response and latency from onset of bipolar disorder (BD) to the start of mood-stabilizer prophylaxis. METHOD: We analyzed our own new data and added findings from research reports identified by computerized searching. RESULTS: We found 11 relevant studies, involving 1485 adult patients diagnosed primarily with BD. Reported latency to prophylaxis averaged 9.6 years (SD 1.3), and follow-up in treatment averaged 5.4 years (SD 3.1). Greater illness intensity and shorter treatment latency were closely associated, resulting in a greater apparent reduction in morbidity with earlier treatment. However, this finding was not sustained after correction for pretreatment morbidity, and treatment latency did not predict morbidity during treatment. Therefore, assessments based on improvement with treatment, or without correction for pretreatment morbidity, can be misleading. CONCLUSIONS: Available evidence does not support the proposal that delayed prophylaxis may limit response to prophylactic treatment in BD and related disorders.     

Twelve-month outcome of adolescents with bipolar disorder following first hospitalization for a manic or mixed episode

OBJECTIVE: Although adolescent-onset bipolar disorder is associated with significant morbidity, there have been few prospective outcome studies of this population. The aim of this study was to examine the 12-month outcome of bipolar adolescents following an initial hospitalization for a manic or mixed episode. METHOD: Bipolar adolescents (N=71) were recruited during their first hospitalization for a manic or mixed episode and were evaluated using diagnostic, symptomatic, and functional assessments. Patients were also evaluated at 1, 4, 8, and 12 months after hospitalization to assess syndromic, symptomatic, and functional outcomes. Predictors of each type of outcome were identified. RESULTS: Kaplan-Meier estimates of the cumulative probabilities of syndromal, symptomatic, and functional recovery and syndromic recurrence during the first 12 months following initial hospitalization were 0.86, 0.43, 0.41, and 0.54, respectively. Only 35% of bipolar adolescents reported full medication adherence. Individual predictors of poor syndromic recovery included co-occurring attention deficit hyperactivity disorder (ADHD), anxiety disorders, and disruptive behavior disorders as well as nonadherence to psychotropic medication and lower socioeconomic levels. Co-occurring alcohol use disorders, treatment with antidepressants, and the absence of psychotherapeutic intervention predicted syndromic recurrence. Boys were more than twice as likely as girls to experience symptomatic recovery. CONCLUSIONS: Most bipolar adolescents experienced syndromic recovery following their first hospitalization. However, rates of symptomatic and functional recoveries were much lower. Future studies examining effective pharmacological and nonpharmacological treatment strategies for bipolar youth with co-occurring disorders and investigating factors that contribute to the development of substance use disorders and treatment adherence in bipolar youth are necessary to improve outcome.     

Awareness of illness in patients with bipolar I disorder with or without comorbid anxiety disorders

BACKGROUND: The present study examined whether specific types of comorbid anxiety disorders, namely panic disorder (PD), social phobia (SP) and obsessive-compulsive disorder (OCD) are differentially associated with course variables and insight into bipolar illness. METHOD: The sample consisted of 151 consecutively hospitalized patients with bipolar I disorder. They were assessed in the week prior to discharge using the Structured Clinical Interview for DSM-III-R (SCID-P), the Brief Psychiatric Rating Scale (BPRS), the Global Assessment of Functioning Scale (GAF) and the Hopkins Symptom Checklist (HSCL-90). Level of insight was assessed with the Scale to assess Unawareness of Mental Disorders (SUMD). RESULTS: Of the 151 bipolar subjects, 92 had no PD, SP and OCD comorbidity, 35 had PD and 24 had SP and/or OCD. The three groups differed significantly on the current awareness of illness and treatment response scores and the retrospective awareness of illness and treatment response scores. Post-hoc analyses revealed that, compared with bipolar patients without PD/SD/OCD and those with comorbid PD, patients with comorbid SP and/or OCD had better insight on current awareness of illness, current awareness of treatment response, retrospective awareness of illness and retrospective awareness of treatment response. The regression analysis showed that the presence of no panic type anxiety comorbidity was a predictor of good insight. CONCLUSIONS: These data indicate the value of identifying comorbid anxiety disorders in patients with bipolar illness. The results could be interpreted as evidence of discrete disorders within the bipolar spectrum, one that is characterized by, among other things, SP and/or OCD with good insight, another characterized by PD with poor insight.     

Efficacy of combined therapy and pharmacotherapy for depressed patients with or without personality disorders

In general, depressed patients with personality pathology--Axis II disorders--respond less well or less quickly to the various kinds of individual treatment that are available, whether pharmacotherapy, psychotherapy, or both combined. This article sets forth the results of a six-month, randomized clinical trial of antidepressants and combined therapy in ambulatory patients with major depression and a baseline score of at least 14 on the 17-item Hamilton Rating Scale for Depression (HAM-D-17). The presence or absence of Axis II pathology was determined on the basis of a self-report version of the International Personality Disorder Examination. The study's antidepressant protocol provided for three successive steps in case of intolerance or inefficacy: fluoxetine, amitriptyline, and moclobemide. In addition to pharmacotherapy, the combined-therapy condition included 16 sessions of Short Psychodynamic Supportive Psychotherapy. Efficacy of the therapy provided was assessed using the HAM-D-17 and also other instruments. According to the results in secondary analyses, it emerged that combined therapy was more effective than pharmacotherapy for depressed patients with personality disorders. Combined therapy was not more effective than pharmacotherapy alone for depressed patients without personality disorders. It is recommended that depressed patients with comorbid personality pathology should be treated with combined therapy, with the focus of psychotherapy being not on the patient's symptoms and complaints, but on all aspects of the patient's actual relationships.     

Hepatitis C testing and infection rates in bipolar patients with and without comorbid substance use disorders

OBJECTIVES: To determine and compare hepatitis C (HCV) screening and testing rates among four groups: those with (i) bipolar disorder [BD group (history of BD but no substance use disorder)]; (ii) substance use disorders [SUD group (history of SUD but no BD)]; (iii) co-occurring disorders [DD group (history of both BD and an SUD)]; and (iv) a control group (no history of either bipolar disorder or substance use disorder). Our hypothesis was that HCV antibody testing rates and HCV prevalence would be higher in the BD, SUD, and DD groups than the control group. METHODS: Data were retrospectively collected on 325,410 patients seen between 1998 and 2004 within facilities and clinics of the Veterans Integrated Service Network (VISN) 20 Northwest Veterans Health Care Administration from electronic medical records. HCV screening and prevalence rates were compared between the BD, SUD, DD, and control groups. Odds ratios and relative risks were determined and compared between groups. RESULTS: Patients in the BD, SUD, and DD groups had been tested at a higher rate than controls and were at increased risk for HCV infection compared with controls. These high-risk groups had a 1.31-fold, 4.86-fold, and 5.46-fold increase in the relative risk of HCV infection, respectively. Overall, compared to the control group, the relative risk of a patient having HCV if he or she had BD (with or without an SUD) was 3.6. CONCLUSIONS: Patients with BD and comorbid SUD had an over fourfold increase in relative risk for HCV than our control group and a similar risk as patients in our SUD group. Furthermore, even if bipolar patients did not have a comorbid SUD (the BD group), their relative risk of HCV was significantly higher than that of the control group. This suggests that patients with BD, particularly those with a comorbid SUD, should be screened and tested for HCV.     

Eating disorders and illness burden in patients with bipolar spectrum disorders

OBJECTIVES: The objectives of the study were to evaluate the clinical significance of lifetime eating disorder comorbidity in a well-defined sample of patients with bipolar spectrum disorders and to describe cognitive correlates of disordered eating in this group. METHOD: Twenty-six bipolar patients with a lifetime history of a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV)-defined eating disorder (n = 17) or a clinically significant subthreshold eating disorder (n = 9) (ED group) were compared with 46 bipolar patients with no history of an eating disorder (no-ED group) on demographic and clinical characteristics at study presentation, history of bipolar illness, and other psychiatric comorbidity. Measures included the Structured Clinical Interview for the DSM-IV Axis I Disorders, the Clinical Global Impression-Severity Scale-Bipolar Version (CGI-S-BP), and the Eating Disorder Examination. Height and weight were recorded to calculate body mass index. RESULTS: Patients in the ED group were heavier and were rated as more symptomatic on the CGI-S-BP than were patients in the no-ED group. The ED group also had a higher number of lifetime depressive episodes and greater psychiatric comorbidity, excluding eating and mood disorders. Finally, after controlling for body mass index and CGI-S-BP rating, patients in the ED group had significantly higher Eating Disorder Examination Restraint, Eating Concern, Shape Concern, Weight Concern, and Global scores than did patients in the no-ED group. CONCLUSIONS: These findings highlight the need for a renewed emphasis on the evaluation and management of weight and eating in the mood disorders. In particular, this research suggests that eating disorder comorbidity may be a marker for increased symptom load and illness burden in bipolar disorder.     

Rehabilitative residential treatment in patients with severe mental disorders: personality features associated with short-term outcome

The aims of this study were to evaluate the outcome of inpatients with severe psychiatric disorders after 6 months of multimodal residential treatment. Ninety-one subjects admitted to residential prolonged treatment at an Italian rehabilitative complex were included in the study. Within 6 months, the program of treatment was effective in reducing symptoms and improving the patients' psychosocial functioning. The study of personality can be useful to "dose" symptomatic (pharmacological and psychotherapeutic) and rehabilitative treatments in the therapy program.     

Impact of comorbid anxiety disorders on outcome in a cohort of patients with bipolar disorder

BACKGROUND: High rates of comorbid anxiety disorders have been described in individuals with bipolar disorder. Although it is well recognized that anxiety disorders often co-occur with bipolar disorder, few studies have examined the impact of more than 1 anxiety disorder on long-term outcome in patients with bipolar disorder. METHOD: The rates of DSM-IV generalized anxiety disorder, panic disorder, social phobia, obsessive-compulsive disorder, and posttraumatic stress disorder were determined using structured clinical interviews in 138 patients with bipolar disorder who presented consecutively between 1994 and 1999. Patients were then followed for up to 3 years with longitudinal clinical surveillance. The impact of 1 or more comorbid anxiety disorders on mood symptoms and general function was evaluated. RESULTS: In our sample, 55.8% of the patients had at least 1 comorbid anxiety disorder, and 31.8% had 2 or more anxiety disorder diagnoses. The most common anxiety disorder was generalized anxiety disorder, followed by panic disorder. The presence of an anxiety disorder led to significantly (p <.05) worse outcome on global as well as specific illness measures, including illness severity, proportion of patients characterized as euthymic, and proportion of the year spent ill. Number of anxiety disorders was less important than type, with generalized anxiety disorder and social phobia having the most negative impact on outcome. CONCLUSION: Our data suggested that multiple anxiety disorder comorbidities were not infrequent in bipolar disorder and that generalized anxiety disorder and social phobia were more likely to be associated with poor outcome. We discuss some potential mechanisms and implications in our findings.     

Longitudinal outcome in patients with bipolar disorder assessed by life-charting is influenced by DSM-IV personality disorder symptoms

Objectives:  Few studies have examined the question of how personality features impact outcome in bipolar disorder (BD), though results from extant work and studies in major depressive disorder suggest that personality features are important in predicting outcome. The primary purpose of this paper was to examine the impact of DSM-IV personality disorder symptoms on long-term clinical outcome in BD.
Methods:  The study used a 'life-charting' approach in which 87 BD patients were followed regularly and treated according to published guidelines. Outcome was determined by examining symptoms over the most recent year of follow-up and personality symptoms were assessed with the Structured Clinical Interview for DSM-IV (SCID-II) instrument at entry into the life-charting study.
Results:  Patients with better outcomes had fewer personality disorder symptoms in seven out of 10 disorder categories and Cluster A personality disorder symptoms best distinguished euthymic and symptomatic patients.
Conclusions:  These results raise important questions about the mechanisms linking personality pathology and outcome in BD, and argue that conceptual models concerning personality pathology and BD need to be further developed. Treatment implications of our results, such as need for psychosocial interventions and treatment algorithms, are also described.     

The interface between borderline personality disorder and bipolar spectrum disorders

OBJECTIVE: This review examines whether borderline personality disorder (BPD) should be considered part of the bipolar spectrum. METHODS: A literature review examined studies of co-occurrence, phenomenology, family prevalence, medication response, longitudinal course, and etiology. RESULTS: Borderline personality disorder and bipolar disorder co-occur, but their relationship is not consistent or specific. There are overlaps but important differences in phenomenology and in medication response. Family studies suggest clear distinctions, and it is unusual for BPD to evolve into bipolar disorder. Research is insufficient to establish whether these disorders have a common etiology. CONCLUSIONS: Existing data fail to support the conclusion that BPD and bipolar disorders exist on a spectrum but allows for the possibility of partially overlapping etiologies.
