Low-dose clozapine in acute and continuation treatment of severe borderline personality disorder

Analysis of antipsychotic drugs prescribing in incarcerated persons in a Serbian correctional facility

PURPOSE

Prison settings have limited resources, and it is of particular interest to analyze which antipsychotics are commonly prescribed in these conditions and to determine the prevalence of the adverse effects.

DESIGN/METHODOLOGY/APPROACH

A cross-sectional, epidemiological survey was used to measure the prevalence of antipsychotic prescribing among adult prisoners in Sremska Mitrovica Prison in 2020.

FINDINGS

The prevalence of antipsychotic use was 7.58%. The most commonly prescribed antipsychotic was clozapine (45.36%), but also olanzapine, haloperidol and risperidone were prescribed. The incidence of extrapyramidal adverse effects was nonexistent and the metabolic parameters did not differ between participants using metabolic syndrome-inducing antipsychotics and those who were prescribed metabolically inert medications. The prescribed doses were lower compared with the recommended.

RESEARCH LIMITATIONS/IMPLICATIONS

This research includes certain points that should be cautiously considered. First, the data were cross-sectional and the findings did not provide causal interpretations. Second, the data are from a single penitentiary institution, albeit the largest in the country; however, that may affect the generalizability of the findings. Third, because the included subjects were not hospitalized, some laboratory analyses were not available, according to the local regulations, and thus the prevalence of metabolic syndrome could not be precisely determined.

PRACTICAL IMPLICATIONS

The prevalence of the antipsychotic use in prison environment is significantly higher than in general population. The most frequently prescribed antipsychotics are clozapine and olanzapine. The prevalence of adverse effects is rare, however, that is possibly due to low doses of the prescribed antipsychotics. The list of therapeutic options available to the incarcerated persons in this facility is also limited. The list of available antipsychotics does not include some atypical antipsychotics with more favorable safety and tolerability profile, such as aripiprazole or cariprazine. Long-acting antipsychotic injectables were also not available to these patients. Laboratory analyses are not regularly conducted and do not include some essential parameters such as lipid status or differential blood count. Low-dose antipsychotics for behavioral symptoms appears to be well tolerated under prison conditions where adherence is assured. It is effective during the prison stay but long-term effects, especially after release from prison, had not been studied.

SOCIAL IMPLICATIONS

This paper advocates for better quality of health care in this correctional facility: more therapeutic options and better laboratory monitoring. The authors justify the use of clozapine in this settings due its benefits in reducing violence and aggression; however, further research would be necessary to clarify does the use of clozapine in incarcerated persons cause behavioral improvements that could result in shorter incarcerations, less recidivism and better quality of life.

ORIGINALITY/VALUE

To the best of the authors' knowledge, this is the first insight of the antipsychotic prescribing practice in Serbia. There is very limited data on prisoners' health care, especially mental health care, in Balkan countries. The antipsychotic prescribing pattern in this sample is characterized with higher than expected clozapine use, but without expected adverse effects.

A systematic review of the role of clozapine for severe borderline personality disorder

RATIONALE

Clozapine is a unique medication with a potential role in the treatment of severe borderline personality disorder (BPD).

OBJECTIVES

The review examines the effectiveness of clozapine as a medication for management for severe BPD with high risk of suicide, violence or imprisonment, and aims to help guide clinical practice in managing severe BPD.

METHODS

A database search of the terms "Clozapine" AND "BPD"; "Antipsychotics" AND "BPD"; "Clozapine" AND "Borderline Personality Disorder"; and "Antipsychotics" AND "Borderline Personality Disorder" were performed in CINAHL, Cochrane Library, Embase, Medline, PsychINFO, PubMed, and Web of Science. Full-text articles of clinical clozapine use for BPD were included for review.

RESULTS

A total of 24 articles consisting of 1 randomised control trial, 10 non-controlled trials, and 13 case reports were identified. Most of the studies reported benefits from clozapine when used for severe BPD. Many of the studies focused on clozapine use in BPD patients at high risk of suicide. Results from these non-controlled and case reports support the use of clozapine in patients with severe BPD at high risk of suicide.

CONCLUSION

There may be a role for clozapine in treating severe treatment refractory BPD, especially for those patients at high risk of suicide and frequent hospitalisations.

The Modernization of Clozapine: A Recapitulation of the Past in the United States and the View Forward

PURPOSE

Although clozapine was Food and Drug Administration (FDA) approved more than 3 decades ago, major barriers and gaps in knowledge continue to prevent its effective and safe use. We review modern-day problems encountered with clozapine in the United States (US).

METHODS

Information surrounding current administrative, clinical, research, and technological gaps or barriers related to clozapine use in the US was reviewed.

FINDINGS

The history of how clozapine became FDA approved likely contributes to gaps in knowledge. The frequency of safety warnings added to the FDA prescribing information may add to fears about clozapine, as evidence by numerous published survey studies. The clozapine Risk Evaluation and Mitigation Strategy (REMS) program has been modified several times in the last decade, causing access and safety issues for patients, which are discussed. Evidence may suggest that the FDA REMS requirements for hematologic monitoring are too cumbersome, and there may be ability to safely loosen requirements. The COVID-19 pandemic brought forth the ability for extended interval monitoring but also greater awareness of the clozapine-inflammation interaction. Newer guidelines published describe considerations in personalizing clozapine titration based on principles of ethnopsychopharmacology. Emerging technologies to support the use of clozapine are not widely available.

IMPLICATIONS

Clozapine is a unique life-saving drug but it is underused in the US, despite its established efficacy. The 2021 REMS changes led to significant difficulties for providers and patients. We highlight the importance of the clozapine-inflammation interaction, therapeutic drug monitoring, and the ability for individual care based on patient-specific factors. There is an urgent need for advancing technology used for clozapine monitoring, evaluating barriers created by REMS, and establishing consistent practices throughout the US.

Low-dose clozapine monotherapy for recurrent non-suicidal self-injury: A case report

Non-suicidal self-injury (NSSI) is a challenging issue in clinical settings. In the present case series, we report two female adolescents with recurrent depression and NSSI. Numerous approaches, such as anti-depressants, anti-psychotics, and even electroconvulsive therapy, were not effective. Clozapine has been implemented in a broad spectrum of psychiatric disorders, particularly refractory depression, impulse control problems, suicidal ideation, and NSSI. With a low dose (12.5-25 mg) of clozapine, the depressive symptoms and NSSI remarkably improved, and the improvement was sustained over four months after discharge. Low-dose clozapine monotherapy may be a treatment option with refractory depression and NSSI.

Current Clinical Psychopharmacology in Borderline Personality Disorder

BACKGROUND

Patients with Borderline Personality Disorder (BPD) manifest affective and behavioral symptoms causing personal distress, relationship difficulties, and reduced quality of life with global functioning impairment, mainly when the disease takes an unfavorable course. A substantial amount of healthcare costs is dedicated to addressing these issues. Many BPD patients receive medications, mostly those who do not respond to psychological interventions.

OBJECTIVE

Our aim was to assess the efficacy of the most used strategies of pharmacological interventions in BPD with a comprehensive overview of the field.

METHODS

We searched the PubMed database for papers focused on the most used psychotropic drugs for BPD. We included randomized controlled trials and open studies in adult patients with BPD, focusing on the efficacy and tolerability of single classes of drugs with respect to specific clinical presentations that may occur during the course of BPD.

RESULTS

Specific second-generation antipsychotics (SGAs) or serotonergic antidepressants can be effective for different core symptoms of BPD, mainly including mood symptoms, anxiety, and impulse dyscontrol. Some atypical antipsychotics can also be effective for psychotic and dissociative symptoms. Specific antiepileptics can be useful in some cases in treating different BPD symptoms, mainly including mood instability, impulsiveness, and anger.

CONCLUSION

No medication is currently approved for BPD, and clinicians should carefully assess the benefits and risks of drug treatment. Further studies are needed to identify specific personalized treatment strategies, also considering the clinical heterogeneity and possible comorbidities of BPD.

Real-World Effectiveness of Clozapine for Borderline Personality Disorder: Results From a 2-Year Mirror-Image Study

While some second-generation antipsychotics have shown efficacy on patients with borderline personality disorder (BPD), limited data exist regarding the effect of clozapine. Thus, we aimed to investigate the effects of clozapine on naturalistic outcomes in BPD patients with a 2-year mirror-image model. Among 25,916 patients with BPD, 1,107 redeemed ≥ 1 clozapine prescription. Of these, 18,188 were "specific" BPD patients, and 102 redeemed ≥ 1 clozapine prescription. During a mean observation period of 598.51 days, in all BPD patients, clozapine was associated with a significant reduction in psychiatric admissions from 2.52 (95% CI [2.31, 2.78]) to 2.00 (95% CI [1.77, 2.23]) admissions (p < .001) and a significant reduction in psychiatric bed-days from 190.08 (95% CI [176.84, 203.33]) to 65.95 (95% CI [58.27, 73.66]) bed-days (p < .001). Similar findings were found for "specific" BPD patients. The number of patients with intentional self-harm or overdose decreased significantly from 189 to 114 individuals (p < .001) after clozapine initiation. Randomized trials evaluating the risk- benefit ratio of clozapine in patients with severe BPD are warranted.

Drug treatment for personality disorders

There is some evidence that antidepressants, particularly the selective serotonin reuptake inhibitors and the monoamine oxidase inhibitors, have some benefits in the management of borderline personality disorder, and lesser evidence (partly because of limited trial data) for the benefits of antipsychotic drugs and mood stabilisers. There is not sufficient distinction between the different personality disorders to recommend that any one disorder should be treated by any one drug, and successful treatment is dependent on careful management, sensitive to the patient's expectations.

Auditory Verbal Hallucinations in Borderline Personality Disorder and the Efficacy of Antipsychotics: A Systematic Review

Background: Auditory verbal hallucinations (AVH) are experienced more frequently by patients with borderline personality disorder (BPD) than previously assumed. However, consensus is lacking on how to treat them. Objective: To provide a systematic review of studies reporting on AVH in patients with BPD, with a focus on the efficacy of treatment of psychotic symptoms. Methods: For this review a systematic search was made in the PubMed and Ovid databases, and mean weighted prevalence rates, adjusted for sample size, were computed. Results: The search yielded 36 studies describing a total of 1,263 patients. Auditory hallucinations (including AVH) were reported in 27% of hospitalized BPD patients; AVH were reported in 25% of all patients and in 24% of outpatients. Of the hallucinating patients, 78% experienced AVH at least once per day, for a duration of several days to many years. On the whole, patients with BPD regarded their voices as malevolent and omnipotent in nature. Compared to patients with schizophrenia, the phenomenological characteristics of AVH were similar and the ensuing distress was equal or even higher, whereas scores for other positive symptoms were lower. The presence of AVH in BPD was associated with an increase of suicide plans and attempts, and more frequent hospitalization. Moreover, AVH in the context of BPD were associated with higher prevalence rates for post-traumatic stress disorder and emotional abuse. The efficacy of antipsychotics was investigated in 21 studies. Based on these studies, we conclude that both typical and atypical antipsychotics tend to have positive effects on AVH experienced in the context of BPD. The efficacy of cognitive-behavioral therapy and non-invasive brain stimulation has not yet been systematically assessed. Conclusions: These findings indicate that AVH experienced in the context of BPD are in need of proper diagnosis and treatment, and that antipsychotics tend to be beneficial in treating these (and other psychotic) symptoms.There is an urgent need for studies assessing the efficacy of cognitive-behavioral therapy and non-invasive brain stimulation in this underdiagnosed and undertreated group.

Impact of Clozapine versus Haloperidol on Conditional Release Time and Rates of Revocation in a Forensic Psychiatric Population

Background

Clozapine remains the cornerstone of treatment for treatment refractory schizophrenia. Clozapine has been shown to improve quality of life and cognitive functioning and to reduce hospital days in psychiatric patients. The impact of clozapine in a forensic population of psychiatric patients has not been studied.

Methods

This study is a naturalistic, retrospective database analysis of forensic patients hospitalized at the Northwest Missouri Psychiatric Rehabilitation Center from January 1, 1990 to August 1, 1999 who were treated with clozapine or haloperidol. Patients were either court ordered for hospitalization as having been found not guilty by reason of insanity or as incompetent to proceed to trial.

Results

Data from 84 patients (69 male, 15 female) were included in the analysis. The primary Axis I diagnoses were substance abuse (n = 61) and schizophrenia (n = 46). Patients had been treated with haloperidol (n = 78) and clozapine (n = 21), and some had received each agent as monotherapy during their course of treatment (n = 15). Assault (n = 22), armed criminal action (n = 18), and burglary (n = 18) were the primary forensic reasons for admission. Of those eligible to obtain a conditional release, 33% of haloperidol-treated patients and 38% of clozapine-treated patients obtained their conditional release on those medications. Haloperidol-treated patients were more likely to have their conditional release revoked (58.8%) versus those treated with clozapine (0%). Clozapine-treated patients were also more likely to stay on conditional release for longer periods of time. Global Assessment of Functioning (GAF) scores improved in both treatment groups; however, of 15 patients converted from haloperidol to clozapine, 93% (n = 14) saw improvements in GAP scores.

Conclusions

Clozapine and haloperidol effectively reduce psychosis and aggression. In our study, clozapine-treated patients were more likely to obtain a conditional release and stayed on conditional release for longer periods of time. Although the need exists to study this patient population more closely from a longitudinal standpoint, one may suspect that these findings represent a potential decrease in healthcare costs for the treatment of forensic psychiatric patients.

Pharmacotherapy of personality disorders: what we know and what we have to search for

Pharmacotherapy for personality disorders is in the early stage of development because the evidence base for effective drug treatment is insufficient, biased toward borderline personality disorder and rampant with methodological issues. In this paper, we reviewed randomized, placebo-controlled trials of drugs efficacy in patients with personality disorders published between 1990 and 2016. Overwhelming majority of studies focused on borderline personality disorder, and the accumulation of evidence resulted in seven meta-analyses, which are interpreted into better strategies for evidence-based practice. Little research attention was given to schizotypal and antisocial personality disorders, with only indirect treatment efficacy evidence for the obsessive–compulsive and avoidant personality disorders. Some avenues for future efficacy research are indicated.

Switching bipolar disorder patients treated with clozapine to another antipsychotic medication: a mirror image study

Bipolar disorder (BD) is associated with periodic symptom exacerbations, leading to functional impairment, and increased risk of suicide. Although clozapine has never been approved for the treatment of BD, it is occasionally used in severe mania. The aim of the study is to evaluate the risks and benefits of switching clozapine in remitted BD patients. This is an observational, mirror image study of 62 consecutive remitted BD outpatients treated with clozapine. Twenty-five patients were switched to another antipsychotic following a change in a drug reimbursement rule, while 37 continued on clozapine. The mean time in remission was shorter for the switched group (9.2±4 months vs 13±6 months, P=0.018), and the number of patients who relapsed was larger (n=21 vs n=8, P<0.0001). The results suggest that switching from clozapine to another antipsychotic may increase the risk of relapses in remitted patients with BD.

Use of Clozapine for Borderline Personality Disorder: A Case Report

Patients with borderline personality disorder (BPD) show significant impairment in functioning, particularly in the interpersonal and social domains. Prior reports suggest that clozapine may be effective in the management of BPD. We present the case of a patient with BPD who experienced persistent suicidal ideation and was treated with clozapine at a state psychiatric hospital. After treatment failure with other psychotropic medications, clozapine medication was initiated; not only did suicidal ideation cease, but social and professional functioning also greatly improved to the point of no longer requiring intensive levels of observation or restrictive procedures. Clozapine appears to be efficacious in the management of suicide attempts and self-injurious behavior. Moreover, it appears to be promising as a therapeutic measure for ameliorating the global functioning of patients with severe BPD. Larger, randomized, blinded, and controlled prospective studies are needed to confirm these findings and to determine optimal dosage.

Second-generation antipsychotic use in borderline personality disorder: What are we targeting?

Introduction:

Borderline personality disorder (BPD) is a personality disorder plagued with high rates of psychotropic polypharmacy. Estimates show that second-generation antipsychotics (SGAs) are used in most of these patients; however, they are being prescribed off label.

Methods:

A literature review was conducted via PubMed in search for studies evaluating SGA use in BPD.

Results:

There are available data investigating 8 of 11 SGAs and their use in BPD. Of N = 269 potential articles, N = 34 evaluating the use of SGAs in BPD were included.

Discussion:

Strong evidence supporting SGAs in BPD is lacking. Potential target symptoms in which a SGA may be useful include depression, anxiety, anger, impulsivity, and paranoia/dissociative behavior.

Experiences of women in secure care who have been prescribed clozapine for borderline personality disorder

BACKGROUND

Clozapine is an atypical antipsychotic medicine which can cause significant side-effects. It is often prescribed off-license in severe cases of borderline personality disorder contrary to national treatment guidelines. Little is known about the experiences of those who take clozapine for borderline personality disorder. We explored the lived-experience of women in secure inpatient care who were prescribed clozapine for borderline personality disorder.

FINDINGS

Adult females (N = 20) participated in audio-taped semi-structured interviews. Transcripts were subject to thematic analysis. The central themes related to evaluation, wellbeing, understanding and self-management; for many, their subjective wellbeing on clozapine was preferred to prior levels of functioning and symptomatology, sometimes profoundly so. The negative and potentially adverse effects of clozapine were explained as regrettable but relatively unimportant.

CONCLUSIONS

When psychological interventions are, at least initially, ineffective then clozapine treatment is likely to be evaluated positively by a group of women with borderline personality disorder in secure care despite the potential disadvantages.

Pharmacotherapy for borderline personality disorder--current evidence and recent trends

Drug treatment of patients with borderline personality disorder (BPD) is common but mostly not supported by evidence from high-quality research. This review summarises the current evidence up to August 2014 and also aims to identify research trends in terms of ongoing randomised controlled trials (RCTs) as well as research gaps. There is some evidence for beneficial effects by second-generation antipsychotics, mood stabilisers and omega-3 fatty acids, while the overall evidence base is still unsatisfying. The dominating role SSRI antidepressants usually play within the medical treatment of BPD patients is neither reflected nor supported by corresponding evidence. Any drug treatment of BPD patients should be planned and regularly evaluated against this background of evidence. Research trends indicate increasing attention to alternative treatments such as dietary supplementation by omega-3 fatty acids or oxytocin.

Clozapine: an effective treatment for seriously violent and psychopathic men with antisocial personality disorder in a UK high-security hospital

OBJECTIVE

A number of studies have demonstrated the anti-aggressive properties of clozapine in schizophrenia and its positive effect in borderline personality disorder. There is no published literature on the treatment of antisocial personality disorder (ASPD) with clozapine. We present a case series of 7 patients with primary ASPD and high psychopathic traits treated with clozapine, having a significant history of serious violence and currently detained in a UK based high-security hospital.

METHODS

A retrospective review of case notes was carried out to formulate Clinical Global Impression (CGI) scores and record incidents of violence and aggression. Effect on specific symptom domains (cognitive-perceptual, impulsive-behavioural dyscontrol, affective dysregulation) was also noted. Metabolic parameters and serum clozapine levels were also sampled.

RESULTS

All 7 patients showed significant improvement on clozapine. It was shown to benefit all symptom domains, especially impulsive behavioral dyscontrol and anger. The number of violent incidents committed by 6 of the 7 patients reduced significantly, and all patients' risk of violence reduced. Clozapine serum levels for 6 of the 7 patients were in the range 150-350 ng/mL.

CONCLUSION

Clozapine is of benefit in reducing the clinical severity of ASPD. It improved all symptom domains, especially impulsive-behavioral dyscontrol and anger, and reduced levels of aggression and violence, especially at lower doses (serum levels <350 ng/m). To our knowledge, this is the first account of clozapine treatment in patients with ASPD and high psychopathy.

The novel use of clozapine in an adolescent with borderline personality disorder

BACKGROUND

Clozapine has been used to good effect in the treatment of adults with borderline personality disorder, but there is scant evidence of it being used in an adolescent population with these difficulties.

METHODS

Clozapine was trialled in an adolescent with a clinical presentation consistent with an emerging borderline personality disorder.

RESULTS

There was a large reduction in the number of incidents involving abuse to staff, or harm to self, in the 8 weeks after commencing clozapine therapy, compared with the 8 weeks prior, and also a large reduction in the number of episodes of the use of seclusion in the 13 weeks after commencing clozapine therapy, compared with the 13 weeks prior. The young person was also able to be reintegrated in to the ward environment once established on clozapine therapy, which had not been possible full-time, for a whole year prior.

CONCLUSIONS

Although limited by involving just one adolescent, this very preliminary data does nonetheless suggest that clozapine may have a role in treating adolescents with emerging borderline personality disorder when other treatment options have been exhausted.

Clozapine for self-injurious behavior in individuals with borderline personality disorder

Prior reports suggest that clozapine can markedly reduce aggression and self-injurious behavior in patients with borderline personality disorder (BPD). We present a series of four patients with BPD and persistent self-injurious behavior treated with clozapine at a state psychiatric hospital. After treatment with clozapine these patients ceased self-injurious behaviors and aggression, and no longer required intensive levels of observation or restrictive procedures. All were successfully discharged from the hospital soon after initiation of clozapine. Clozapine appears to be efficacious in the management of chronic suicidality, self-injurious behaviors and aggression in patients with severe BPD.

Psychotic symptoms in patients with borderline personality disorder: prevalence and clinical management

PURPOSE OF REVIEW

The aim of this article is to review findings on the prevalence, phenomenology and treatment of psychotic features in borderline personality disorder (BPD), and to discuss factors that might be related to their occurrence.

RECENT FINDINGS

Of patients with BPD about 20-50% report psychotic symptoms. Hallucinations can be similar to those in patients with psychotic disorders in terms of phenomenology, emotional impact, and their persistence over time. Although more research is needed on the exact nature of psychotic phenomena in patients with BPD, terms like pseudo-psychotic or quasi-psychotic are misleading and should be avoided. Childhood trauma might play an important role in the development of psychotic symptoms in patients with BPD, as in other populations. More research is necessary on the role of comorbid disorders, especially posttraumatic stress disorder (PTSD). Atypical antipsychotics seem to be beneficial in some patients; evidence on psychotherapy of psychotic symptoms is sparse.

SUMMARY

Psychotic symptoms, especially hallucinations, seem to be an important feature of BPD. More research on potential mediators and adequate treatment approaches for psychotic symptoms in BPD is needed, and current diagnostic systems might require revision to emphasise psychotic symptoms.

Borderline personality disorder: current drug treatments and future prospects

Individuals with borderline personality disorder (BPD) suffer from marked affective disturbance, an unstable sense of self, difficulty in interpersonal relationships and heightened impulsivity, leading to high rates of self-harm and suicide. Patients are often refractory to treatment and are at high risk for acute or dangerous presentations, with a serious impact on mental health services. There has been much debate on the effectiveness of pharmacotherapy in treating different facets of the psychopathology of the disorder. Several guidelines recommend the use of antidepressant agents, mood stabilizers for affective dysregulation and impulsive-behavioural dyscontrol, and antipsychotics for cognitive-perceptual symptoms. However, concerns have recently been raised regarding the strength of evidence for these treatment recommendations in BPD. Here, we review the evidence for efficacy of the main psychotropic medications used in BPD, drawing, in particular, on evidence from randomized controlled trials and meta-analyses. Overall, meta-analysis provides little evidence to support the use of antidepressant medication in BPD outside episodes of major depression. However, there is evidence for the use of both mood stabilizers and antipsychotic medications for the treatment of specific aspects of the disorder. Most existing studies have been conducted on small numbers of patients, and there is a requirement for further large-scale trials to substantiate these findings. In addition, given the limitations of current pharmacological treatment of BPD, there is a pressing need to investigate potential new therapeutic targets, including neuropeptides, such as the opioids and vasopressin, and drugs targeted at ameliorating the biological effects of early life stress.

Borderline personality disorder: bipolarity, mood stabilizers and atypical antipsychotics in treatment

In this article, it is aimed to review the efficacies of mood stabilizers and atypical antipsychotics, which are used commonly in psychopharmacological treatments of bipolar and borderline personality disorders. In this context, common phenomenology between borderline personality and bipolar disorders and differential features of clinical diagnosis will be reviewed in line with the literature. Both disorders can demonstrate common features in the diagnostic aspect, and can overlap phenomenologically. Concomitance rate of both disorders is quite high. In order to differentiate these two disorders from each other, quality of mood fluctuations, impulsivity types and linear progression of disorders should be carefully considered. There are various studies in mood stabilizer use, like lithium, carbamazepine, oxcarbazepine, sodium valproate and lamotrigine, in the treatment of borderline personality disorder. Moreover, there are also studies, which have revealed efficacies of risperidone, olanzapine and quetiapine as atypical antipsychotics. It is not easy to differentiate borderline personality disorder from the bipolar disorders. An intensively careful evaluation should be performed. This differentiation may be helpful also for the treatment. There are many studies about efficacy of valproate and lamotrigine in treatment of borderline personality disorder. However, findings related to other mood stabilizers are inadequate. Olanzapine and quetiapine are reported to be more effective among atypical antipsychotics. No drug is approved for the treatment of borderline personality disorder by the entitled authorities, yet. Psychotherapeutic approaches have preserved their significant places in treatment of borderline personality disorder. Moreover, symptom based approach is recommended in use of mood stabilizers and atypical antipsychotics.

A systematic review of the evidence of clozapine's anti-aggressive effects

Reducing the risk of violent and aggressive behaviour in patients with schizophrenia remains a clinical priority. There is emerging evidence to suggest that the second-generation antipsychotic, clozapine, is effective at reducing this risk in patients with schizophrenia and some evidence to suggest that it may be best in selected patients. We conducted a systematic literature search in March 2011 of all prospective and retrospective studies, which investigated clozapine's anti-aggressive effects in a variety of mental disorders. The review identified six animal studies, four randomized controlled trials, 12 prospective non-controlled studies and 22 retrospective studies, with four case studies. We found considerable evidence in support of clozapine's ability to reduce violent and aggressive behaviour. Clozapine's anti-aggressive effect was most commonly explored in patients with schizophrenia, with less evidence available for other psychiatric disorders, including borderline personality disorder, autistic spectrum disorders, post-traumatic stress disorder, bipolar disorder and learning disability. There was mixed evidence to address the question of whether or not clozapine was any more effective than other antipsychotics. In the case of schizophrenia, there was evidence to suggest that clozapine's anti-aggressive effect was more marked particularly in those with treatment-resistant illness. Its anti-aggressive effects appeared to be 'specific', being to some extent greater than both its more general antipsychotic and sedative effects. There were significant methodological inconsistencies in the studies we identified, particularly surrounding patient recruitment criteria, the definition and measurement of violence and the lack of randomized, controlled trials. Data on therapeutic monitoring were also limited. Clozapine can reduce violence and persistent aggression in patients with schizophrenia and other psychiatric disorders. It may offer an advantage over other antipsychotics, although perhaps exclusively in the case of traditionally defined 'treatment resistance' or more broadly defined 'complex cases' with co-morbidity. Larger, randomized, blinded, controlled studies with robust characterization of participants, and standardized measures of violence and aggression are, however, needed to fully understand this link and explore the possible mechanisms.

Medication for borderline personality disorder: a survey at a secure hospital

OBJECTIVES

To study the use of medication in the treatment of inpatients with borderline personality disorder (BPD). To survey clinicians' views on the UK National Institute for Health and Clinical Excellence (NICE) Guideline on BPD.

METHODS

Cross-sectional survey of the use of psychotropics purely for BPD at a large secure UK psychiatric hospital, together with interviews with the treating psychiatrists.

RESULTS

A total of 79 patients had a DSM diagnosis of BPD, of whom 80% were receiving one or more psychotropics and 48% were receiving two or more. Most prescriptions were off-label. Antipsychotics followed by antidepressants were the most frequent class of drug prescribed for BPD. Clozapine was the most commonly prescribed drug and according to the treating psychiatrists the one most likely to lead to a major improvement in target symptoms. Other psychotropics were generally rated as resulting in minor improvement or no change. Clinicians were aware they were prescribing contrary to NICE but justified this on the basis of having to treat severe and complex cases.

CONCLUSIONS

Use of psychotropics (especially clozapine), off-label prescribing and polypharmacy were very common in these inpatients with BPD. Randomised controlled trials of the use of clozapine in severe BPD are needed.

Clozapine use in schizophrenia: findings of the Research on Asia Psychotropic Prescription (REAP) studies from 2001 to 2009

OBJECTIVE

Optimizing treatment and outcomes for people with schizophrenia requires understanding of how evidence-based treatments are utilized. Clozapine is the most effective antipsychotic drug for treatment-refractory schizophrenia, but few studies have investigated trends and patterns of its use over time internationally. This study examined the prescription patterns of clozapine and its demographic and clinical correlates in Asia from 2001 to 2009.

METHOD

Clozapine prescriptions were collected in a sample of 6761 hospitalized schizophrenia patients in nine Asian countries and regions using a standardized protocol and data collection procedure.

RESULTS

Overall, the proportion of patients receiving clozapine prescriptions was stable across the three surveys from 2001 to 2009, ranging from 14.5% to 15.9%. However, the rates and patterns observed within different regions and countries at each survey differed considerably. Clozapine use decreased significantly over time in China, while it increased in Korea and Singapore. Multiple logistic regression analysis revealed that patients taking clozapine were significantly younger, had a higher dose of antipsychotic drugs in chlorpromazine equivalents, were more likely to be female, had fewer extrapyramidal symptoms, and had more negative symptoms, admissions and weight gain in the past month than those not receiving clozapine.

CONCLUSION

The variability in overall rates and changes in prescription rates over time in these samples suggest that factors other than psychopharmacological principles play an important role in determining the use of clozapine in schizophrenia in Asia.

Antipsychotics, antidepressants, anticonvulsants, and placebo on the symptom dimensions of borderline personality disorder: a meta-analysis of randomized controlled and open-label trials

The aim of this study was to quantitatively review randomized controlled trials (RCTs) and open-label trials analyzing the efficacy of antidepressants, mood stabilizers, and antipsychotics for the treatment of the core symptoms of borderline personality disorder (BPD). Using a similar meta-analytic approach, the efficacy of placebo on the same core symptoms of BPD was evaluated. The risk of discontinuation of each of the medication classes reported in the studies was also analyzed to establish the major causes of discontinuation. MEDLINE (1966 to June 2010) and EMBASE (1980 to June 2010) databases were systematically searched to identify relevant RCTs and open studies. The primary outcome was improvement in the specific core symptoms of the disorder: affective dysregulation, impulsive-behavioral dyscontrol, and cognitive-perceptual symptoms. Evidence from RCTs and open studies suggests that drug treatment, especially with mood stabilizers and antipsychotics, may be effective for treating affective dysregulation and impulsive-behavioral dyscontrol. Antipsychotics were also effective in reducing cognitive-perceptual symptoms. Antidepressants failed to show efficacy in treating BPD symptom dimensions other than affective dysregulation. Our analyses of the placebo arm of RCTs showed a significant improvement of symptomatology in these patients also. There were no significant differences in overall dropout rates between patients on medications and those on placebo. In conclusion, the efficacy of pharmacological treatment on the symptom dimensions of BPD has been shown by various independent meta-analyses, with a positive effect of drug treatment on the core symptoms of BPD and some documentable differences in terms of efficacy between different drug classes in each of the symptom domains.

Paliperidone ER in the Treatment of Borderline Personality Disorder: A Pilot Study of Efficacy and Tolerability

Antipsychotics are recommended for the treatment of impulsive dyscontrol and cognitive perceptual symptoms of borderline personality disorder (BPD). Three reports supported the efficacy of oral risperidone on BPD psychopathology. Paliperidone ER is the metabolite of risperidone with a similar mechanism of action, and its osmotic release reduces plasmatic fluctuations and antidopaminergic effects. The aim of this study is to evaluate efficacy and safety of paliperidone ER in BPD patients. 18 outpatients with a DSM-IV-TR diagnosis of BPD were treated for 12 weeks with paliperidone ER (3-6 mg/day). They were assessed at baseline, week 4, and week 12, using the CGI-Severity item, the BPRS, the HDRS, the HARS, the SOFAS, the BPD Severity Index (BPDSI), and the Barratt Impulsiveness Scale (BIS-11). Adverse events were evaluated with the DOTES. Paliperidone ER was shown to be effective and well tolerated in reducing severity of global symptomatology and specific BPD symptoms, such as impulsive dyscontrol, anger, and cognitive-perceptual disturbances. Results need to be replicated in controlled trials.

Classifying personality disorder according to severity

Current systems for classifying personality disorder according to specific categories are unsatisfactory because they do not take account of wide variations in levels of personality disturbance and associated impairment. We review previous attempts to classify personality disorder according to severity and place these findings in the context of work exploring the severity of other mental disorders. On the basis of these findings, we propose a new system for classifying personality-related problems based on severity defined by the extent of personality disturbance, the level of social dysfunctioning, and the impact of the disorder for individuals and society. We recognize that studies using these definitions will need piloting and testing in field trials, but believe that this simplified approach to classifying personality disorder would encourage greater use by clinicians and assist those involved in planning services for people with personality disorder.

Treatment of severe borderline personality disorder with clozapine

Patients with borderline personality disorder (BPD) show significant impairment in the domain of interpersonal and social functioning and may use the resources of health and social services extensively, with little beneficial outcome. At present there are no clear guidelines in literature for the use of pharmacotherapy in the management of BPD. According to the scanty literature available in the form of case reports and small studies, clozapine has been demonstrated to be effective in the management of BPD. The case presented here describes the effectiveness of clozapine in a young female patient with severe BPD (without psychotic features), who had repeated and prolonged periods of hospitalization and was successfully treated with a moderate dose of clozapine, following a failure to improve with other psychotropic medications. More studies are suggested to evaluate the efficacy of clozapine in patients with BPD, both with and without psychotic features, to find out the optimum dose and to weigh the risk and benefits of clozapine.

Pharmacological interventions for borderline personality disorder

BACKGROUND

Drugs are widely used in borderline personality disorder (BPD) treatment, chosen because of properties known from other psychiatric disorders ("off-label use"), mostly targeting affective or impulsive symptom clusters.

OBJECTIVES

To assess the effects of drug treatment in BPD patients.

SEARCH STRATEGY

We searched bibliographic databases according to the Cochrane Developmental, Psychosocial and Learning Problems Group strategy up to September 2009, reference lists of articles, and contacted researchers in the field.

SELECTION CRITERIA

Randomised studies comparing drug versus placebo, or drug versus drug(s) in BPD patients. Outcomes included total BPD severity, distinct BPD symptom facets according to DSM-IV criteria, associated psychopathology not specific to BPD, attrition and adverse effects.

DATA COLLECTION AND ANALYSIS

Two authors selected trials, assessed quality and extracted data, independently.

MAIN RESULTS

Twenty-eight trials involving a total of 1742 trial participants were included. First-generation antipsychotics (flupenthixol decanoate, haloperidol, thiothixene); second-generation antipsychotics (aripirazole, olanzapine, ziprasidone), mood stabilisers (carbamazepine, valproate semisodium, lamotrigine, topiramate), antidepressants (amitriptyline, fluoxetine, fluvoxamine, phenelzine sulfate, mianserin), and dietary supplementation (omega-3 fatty acid) were tested. First-generation antipsychotics were subject to older trials, whereas recent studies focussed on second-generation antipsychotics and mood stabilisers. Data were sparse for individual comparisons, indicating marginal effects for first-generation antipsychotics and antidepressants.The findings were suggestive in supporting the use of second-generation antipsychotics, mood stabilisers, and omega-3 fatty acids, but require replication, since most effect estimates were based on single studies. The long-term use of these drugs has not been assessed.Adverse event data were scarce, except for olanzapine. There was a possible increase in self-harming behaviour, significant weight gain, sedation and changes in haemogram parameters with olanzapine. A significant decrease in body weight was observed with topiramate treatment. All drugs were well tolerated in terms of attrition.Direct drug comparisons comprised two first-generation antipsychotics (loxapine versus chlorpromazine), first-generation antipsychotic against antidepressant (haloperidol versus amitriptyline; haloperidol versus phenelzine sulfate), and second-generation antipsychotic against antidepressant (olanzapine versus fluoxetine). Data indicated better outcomes for phenelzine sulfate but no significant differences in the other comparisons, except olanzapine which showed more weight gain and sedation than fluoxetine. The only trial testing single versus combined drug treatment (olanzapine versus olanzapine plus fluoxetine; fluoxetine versus fluoxetine plus olanzapine) yielded no significant differences in outcomes.

AUTHORS' CONCLUSIONS

The available evidence indicates some beneficial effects with second-generation antipsychotics, mood stabilisers, and dietary supplementation by omega-3 fatty acids. However, these are mostly based on single study effect estimates. Antidepressants are not widely supported for BPD treatment, but may be helpful in the presence of comorbid conditions. Total BPD severity was not significantly influenced by any drug. No promising results are available for the core BPD symptoms of chronic feelings of emptiness, identity disturbance and abandonment. Conclusions have to be drawn carefully in the light of several limitations of the RCT evidence that constrain applicability to everyday clinical settings (among others, patients' characteristics and duration of interventions and observation periods).

Borderline personality disorder and psychosis: a review

Early views of borderline personality disorder (BPD) were based on the idea that patients with this pathology were "on the border" of psychosis. However, more recent studies have not supported this view, although they have found evidence of a malevolent interpersonal evaluation and a significant proportion of BPD patients showing psychotic symptoms. For example, in one study, 24% of BPD patients reported severe psychotic symptoms and about 75% had dissociative experiences and paranoid ideation. Thus, we start with an overview regarding the prevalence of psychotic symptoms in BPD patients. Furthermore, we report findings of studies investigating the role of comorbidity (eg, post-traumatic stress disorder) in the severity and frequency of psychotic symptoms in BPD patients. We then present results of genetic and neurobiological studies comparing BPD patients with patients with schizophrenia or nonschizophrenic psychotic disorders. In conclusion, this review reveals that psychotic symptoms in BPD patients may not predict the development of a psychotic disorder but are often permanent and severe and need careful consideration by clinicians. Therefore, adequate diagnosis and treatment of psychotic symptoms in BPD patients is emphasized.

Olanzapine for the treatment of borderline personality disorder: variable dose 12-week randomised double-blind placebo-controlled study

BACKGROUND

Despite the prevalence and clinical significance of borderline personality disorder, its treatment remains understudied.

AIMS

To evaluate treatment with variably dosed olanzapine in individuals with borderline personality disorder.

METHOD

In this 12-week randomised, double-blind trial, individuals received olanzapine (2.5-20 mg/day; n=155) or placebo (n=159) (trial registry: NCT00091650). The primary efficacy measure was baseline to end-point change on the Zanarini Rating Scale for Borderline Personality Disorder (ZAN-BPD) using last-observation-carried-forward methodology.

RESULTS

Both olanzapine and placebo groups showed significant improvements but did not differ in magnitude at end-point (-6.56 v. -6.25, P=0.661). Response rates (50% reduction in ZAN-BPD) were 64.7% with olanzapine and 53.5% with placebo (P=0.062); however, time to response was significantly shorter for olanzapine (P=0.022). Weight gain was significantly greater (2.86 v. -0.35 kg, P<0.001), with higher incidence of treatment-emergent abnormal high levels of prolactin for the olanzapine group.

CONCLUSIONS

Individuals treated with olanzapine and placebo showed significant but not statistically different improvements on overall symptoms of borderline personality disorder. The types of adverse events observed with olanzapine treatment appeared similar to those observed previously in adult populations.

Efficacy and tolerability of aripiprazole augmentation in sertraline-resistant patients with borderline personality disorder

Information is available on aripiprazole as a treatment for borderline personality disorder (BPD), but no data have yet been presented concerning the use of this drug as an adjunctive treatment for drug-resistant BPD patients. This study investigates aripiprazole augmentation of ongoing sertraline therapy in drug-resistant BPD patients. Twenty-one outpatients with a DSM-IV-TR diagnosis of BPD who did not respond to sertraline, 100-200 mg/day for 12 weeks, were treated for 12 weeks with the addition of aripiprazole, 10-15 mg/day. Patients were assessed at baseline, week 4, and week 12 with the Clinical Global Impression Scale - Severity item (CGI-S), the Brief Psychiatric Rating Scale (BPRS), the Hamilton scales for depression and anxiety (HAM-D, HAM-A), the Social Occupational Functioning Assessment Scale (SOFAS) for social functioning, the Borderline Personality Disorder Severity Index (BPDSI), and the Barratt Impulsiveness Scale (BIS-11). Adverse effects were evaluated using the Dosage Record and Treatment Emergent Symptom Scale (DOTES). Sixteen patients completed the study. Five patients (23.8%) dropped out due to anxiety/insomnia or non-compliance. Nine patients (56.3%) were responders. Analysis of variance revealed significant changes in the following measures: CGI-S, BPRS, BPDSI total score, BPDSI "impulsivity" and "dissociation/paranoid ideation" items, and BIS-11. Adverse effects were mild headache, insomnia, and anxiety. Aripiprazole is an efficacious and well-tolerated add-on treatment for sertraline-resistant BPD patients. It acts on impulsive and psychotic-like symptoms.

Efficacy and tolerability of pharmacotherapies for borderline personality disorder

Borderline personality disorder is a pervasive pattern of instability of interpersonal relationships, affects and self-image, as well as marked impulsivity. Although psychotherapy is needed to attain lasting improvements in a patient's personality and overall functioning, practice guidelines state that pharmacotherapy is indicated to manage state symptoms and trait vulnerabilities. Three psychopathological dimensions are the main targets for pharmacotherapy of borderline personality disorder: affective dysregulation, impulsive-behavioural dyscontrol and cognitive-perceptual symptoms. Guidelines recommend the use of antidepressant agents and mood stabilizers for affective dysregulation and impulsive-behavioural dyscontrol, and antipsychotics for cognitive-perceptual symptoms. This review aims to report and discuss data from clinical trials, reviews and meta-analyses concerning drug efficacy and tolerability in the treatment of borderline personality disorder. Investigations that considered antidepressant agents mainly focused on SSRIs, which are recommended as first-line treatments for affective instability and impulse dyscontrol. Both open-label and randomized controlled studies have been performed, predominantly concerning the efficacy of fluoxetine and fluvoxamine. Other classes of antidepressants, such as TCAs and MAOIs, were investigated as alternative treatments for borderline personality disorder, but the risk of adverse effects and toxicity is a limitation to their use in clinical practice. Increasing amounts of data have recently been collected on the use of mood stabilizers to control mood instability and impulsivity in patients with borderline personality disorder. More substantial data were derived from controlled trials of valproate semisodium, although other drugs such as lithium, carbamazepine, oxcarbazepine and lamotrigine were tested with promising results. Several first-generation antipsychotics were studied in open-label and controlled trials, with good effects on behavioural dyscontrol and psychotic-like symptoms. Selection biases and heterogeneity of drugs and methods somewhat limited the value of these results. More recent investigations have examined atypical antipsychotics, with most of these studies being open-label trials with small sample sizes; however, a few controlled studies have been performed using olanzapine, showing improvements in impulsivity, anger and hostility. In conclusion, a large number of different drugs have been evaluated in the treatment of patients with borderline personality disorder. Initial findings are encouraging for many of these drugs. However, data need to be replicated in further controlled studies with head-to-head comparisons and long-term follow-ups. Many questions remain to be answered.

Aripiprazole in children and adolescents with Tourette disorder with and without explosive outbursts

OBJECTIVE

We conducted a retrospective, observational study of aripiprazole for the treatment of tics and/or co-morbid explosive outbursts in 37 children and adolescents with Tourette disorder (TD).

METHOD

Thirty seven children and adolescents with TD, with and without explosive outbursts, and refractory to previous treatment were treated at one of two university affiliated specialty clinics. All diagnoses were made using Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text Revision (DSM-IV-TR) criteria. Tic severity was rated using the Clinical Global Impressions Scale for tics (CGI-Tics) and frequency of explosive outbursts was assessed using the CGI-Rage; both measures were obtained at pretreatment baseline and at posttreatment follow up.

RESULTS

High rates of psychiatric co-morbidity were observed in these subjects: 31 of 37 (84%) subjects met criteria for obsessive-compulsive disorder (OCD), and 31 of 37 (84%) met criteria for attention-deficit/hyperactivity disorder (ADHD). Twenty nine of 37 (78%) subjects met criteria for intermittent explosive disorder (IED) minus criterion C; the remaining 8 subjects had TD only. Eight subjects (22%) discontinued treatment before 12 weeks due to inability to tolerate the drug. At follow up, tics reduced at a mean daily dose of 12.3 (7.50) mg in 29 of 29 (100%) subjects who completed the study, and explosive outbursts improved in 24/25 subjects (96%) who completed the study. Aripiprazole was tolerated reasonably well, although 8/37 (22%) subjects discontinued treatment; most common side effects included weight gain, akathisia, and sedation.

CONCLUSION

Aripiprazole should be investigated further as a treatment option for TD with and without co-morbid explosive outbursts.

World Federation of Societies of Biological Psychiatry (WFSBP) guidelines for biological treatment of personality disorders

These practical guidelines for the biological treatment of personality disorders in primary care settings were developed by an international Task Force of the World Federation of Societies of Biological Psychiatry (WFSBP). They embody the results of a systematic review of all available clinical and scientific evidence pertaining to the biological treatment of three specific personality disorders, namely borderline, schizotypal and anxious/avoidant personality disorder in addition to some general recommendations for the whole field. The guidelines cover disease definition, classification, epidemiology, course and current knowledge on biological underpinnings, and provide a detailed overview on the state of the art of clinical management. They deal primarily with biological treatment (including antidepressants, neuroleptics, mood stabilizers and some further pharmacological agents) and discuss the relative significance of medication within the spectrum of treatment strategies that have been tested for patients with personality disorders, up to now. The recommendations should help the clinician to evaluate the efficacy spectrum of psychotropic drugs and therefore to select the drug best suited to the specific psychopathology of an individual patient diagnosed for a personality disorder.

John D, Pfohl B, Stuart S, McCormick B, Allen J, Arndt S, Black DW. Systems Training for Emotional Predictability and Problem Solving (STEPPS) for outpatients with borderline personality disorder: a randomized controlled trial and 1-year follow-up

OBJECTIVE

Systems Training for Emotional Predictability and Problem Solving (STEPPS) is a 20-week manual-based group treatment program for outpatients with borderline personality disorder that combines cognitive behavioral elements and skills training with a systems component. The authors compared STEPPS plus treatment as usual with treatment as usual alone in a randomized controlled trial.

METHOD

Subjects with borderline personality disorder were randomly assigned to STEPPS plus treatment as usual or treatment as usual alone. Total score on the Zanarini Rating Scale for Borderline Personality Disorder was the primary outcome measure. Secondary outcomes included measures of global functioning, depression, impulsivity, and social functioning; suicide attempts and self-harm acts; and crisis utilization. Subjects were followed 1 year posttreatment. A linear mixed-effects model was used in the analysis.

RESULTS

Data pertaining to 124 subjects (STEPPS plus treatment as usual [N=65]; treatment as usual alone [N=59]) were analyzed. Subjects assigned to STEPPS plus treatment as usual experienced greater improvement in the Zanarini Rating Scale for Borderline Personality Disorder total score and subscales assessing affective, cognitive, interpersonal, and impulsive domains. STEPPS plus treatment as usual also led to greater improvements in impulsivity, negative affectivity, mood, and global functioning. These differences yielded moderate to large effect sizes. There were no differences between groups for suicide attempts, self-harm acts, or hospitalizations. Most gains attributed to STEPPS were maintained during follow-up. Fewer STEPPS plus treatment as usual subjects had emergency department visits during treatment and follow-up. The discontinuation rate was high in both groups.

CONCLUSIONS

STEPPS, an adjunctive group treatment, can deliver clinically meaningful improvements in borderline personality disorder-related symptoms and behaviors, enhance global functioning, and relieve depression.

Efficacy of quetiapine for impulsivity and affective symptoms in borderline personality disorder

Data on the efficacy of quetiapine in borderline personality disorder (BPD) are still scarce. We aimed to investigate the efficacy of quetiapine for impulsivity and a broad range of affective symptoms in BPD. In this 12-week open-label study, we included individuals with BPD who presented to psychiatric in- and outpatient services. After a gradual titration of quetiapine, a flexible dose (range, 100-800 mg) was administered. The main outcome measures consisted of the scores on patient-rated questionnaires (Barratt Impulsiveness Scale, Buss-Durkee Hostility Inventory, Affective Lability Scale, Spielberger State and Trait Anxiety Inventory, Spielberger State and Trait Anger Inventory, and Beck Depression Inventory) and on neurocognitive tasks related to impulsivity (Stroop Color Word Task and IOWA Gambling Task). A mixed linear model, correcting for age, sex, antidepressant use, and weeks in psychotherapy, was applied. Forty-one patients (34 females and 7 males; mean [SD] age, 27.0 [9.0] years) were enrolled in the study, 32 of which completed the trial. Patients' scores decreased significantly (mean [SD] difference; P value) on the Barratt Impulsiveness Scale (19.7 [2.0]; P < 0.0001), Buss-Durkee Hostility Inventory (11.5 [1.4]; P < 0.0001), Affective Lability Scale (0.75 [0.08]; P < 0.0001), Beck Depression Inventory (25.0 [1.7]; P < 0.0001), Spielberger State and Trait Anxiety Inventory state (19.9 [1.9]; P < 0.0001) and trait (20.8 [1.7]; P < 0.0001) subscale, and Spielberger State and Trait Anger Inventory state (7.3 [1.1]; P < 0.0001) and trait (10.1 [1.0]; P < 0.0001) subscale. In addition, patients showed significantly less inference on the Stroop Color Word Task and had more 'good choices' on the IOWA Gambling Task. These results suggest that quetiapine may be efficacious in the treatment of impulsivity and affective symptoms in BPD.

[Treatment of borderline personality disorder with atypical antipsychotic drugs]

Pharmacotherapy of Borderline personality disorder with atypical antipsychotics has recently been the subject of several mostly small studies and case reports. In contrast to the frequent clinical use of this substance class in borderline patients the amount of data on that subject is still sparse. The clinical data gathered thus far suggest a potential use of atypical antipsychotics in the areas of psychotic symptoms, impulsivity and possibly affective symptoms. The drugs were sufficiently well tolerated; however, the observation period in most studies was short and the dosage low. The current set of clinical data does not support the frequently applied polypharmacy. However, recent data suggest that a therapeutic approach combining atypical antipsychotics and psychotherapy may reveal synergistic effects. Future trials should study larger sample sizes over a longer period of time. Open questions are the required dose and the optimal treatment duration.

Epidemiology, risk factors, and psychopharmacological management of suicidal behavior in borderline personality disorder

Borderline personality disorder (BPD) is a chronic psychiatric condition characterized by a pervasive pattern of instability in affect regulation and impulse control. These maladaptive coping strategies predispose individuals with BPD to suicidal behavior, and this diagnosis increases the risk for completed suicide. Empirical data indicate that adverse life events; a history of childhood trauma; and the presence of comorbid psychiatric conditions, in particular major depressive disorder and substance use disorders; confer an elevated risk of suicidal behavior in patients with BPD. Psychopharmacological interventions, including the use of antidepressants, anti-psychotics, and mood stabilizers, are considered in this review in terms of the evidence for their utility in reducing the risk of suicidal behavior in BPD.

Medications in the treatment of borderline personality disorder 2006

This review covers all significant randomized controlled trials and open trials of medications for the treatment of borderline personality disorder. New developments in the effectiveness of mood stabilizers and antipsychotics are discussed. Differences were found in the effectiveness of medications based on the presence or absence of depression and significant anger symptoms. Medications continue to be recommended as adjuncts to psychotherapy. Most of the trials discussed require replication, and more trials that investigate the effectiveness of medications in combination with psychotherapy are recommended.

Quetiapine for the treatment of borderline personality disorder; an open-label study

PURPOSE

Only a few studies have commented on the use of atypical antipsychotics for the treatment of Borderline Personality Disorder (BPD) features, including affective dysregulation and aggression. We aimed at evaluating both efficacy and safety of quetiapine in a sample of consecutive BPD patients.

GENERAL METHODS

29 BPD outpatients entered, and 23 completed, a 12 week, open-label, regime of quetiapine at an average daily dosage of 540 mg (range: 400-800 mg). Efficacy assessment psychometric instruments included: Hamilton Rating Scales for Depression (HAM-D); Brief Psychiatric Rating Scale (BPRS); Global Assessment of Functioning (GAF); Clinical Global Impression Scale (CGI); and Aggression Questionnaire (AQ).

FINDINGS

Both completer and intent-to-treat analysis showed that most psychometric scales' scores exhibited a highly significant (HAM-D: p=.003; BPRS Hostility and Suspiciousness subscales; CGI; GAF; AQ: all at p=.000) improvement over time. Six patients dropped out early from treatment due to side effects; quetiapine was associated with two cases of transient thrombocytopenia.

CONCLUSIONS

Present findings would suggest that quetiapine may be effective for the treatment of a number of BPD features, including low mood and aggression. However, monitoring blood counts in patients receiving quetiapine seems to be justified.
