The concordance of ICD-10 acute and transient psychosis and DSM-IV brief psychotic disorder.

BACKGROUND: ICD-10 acute and transient psychotic disorder (ATPD; F23) and DSM-IV brief psychotic disorder (BPD; 298.8) are related diagnostic concepts, but little is known regarding the concordance of the two definitions. METHOD: During a 5-year period all in-patients with ATPD were identified; DSM-IV diagnoses were also determined. We systematically evaluated demographic and clinical features and carried out follow-up investigations at an average of 22 years after the index episode using standardized instruments. RESULTS: Forty-two (4.1%) of 1036 patients treated for psychotic disorders or major affective episode fulfilled the ICD-10 criteria of ATPD. Of these, 61.9% also fulfilled the DSM-IV criteria of brief psychotic disorder; 31.0%, of schizophreniform disorder; 2.4%, of delusional disorder; and 4.8%. of psychotic disorder not otherwise specified. BPD showed significant concordance with the polymorphic subtype of ATPD, and DSM-IV schizophreniform disorder showed significant concordance with the schizophreniform subtype of ATPD. BPD patients had a significantly shorter duration of episode and more acute onset compared with those ATPD patients who did not meet the criteria of BPD (non-BPD). However, the BPD group and the non-BPD group of ATPD were remarkably similar in terms of sociodemography (especially female preponderance), course and outcome, which was rather favourable for both groups. CONCLUSIONS: DSM-IV BPD is a psychotic disorder with broad concordance with ATPD as defined by ICD-10. However, the DSM-IV time criteria for BPD may be too narrow. The group of acute psychotic disorders with good prognosis extends beyond the borders of BPD and includes a subgroup of DSM-IV schizophreniform disorder.

Depot flupenthixol decanoate for schizophrenia or other similar psychotic disorders.

BACKGROUND: Anti-psychotic drugs are the mainstay treatment for schizophrenia and similar psychotic disorders. Long-acting depot injections of drugs such as flupenthixol decanoate are extensively used as a means of long-term maintenance treatment. OBJECTIVES: To evaluate the effects flupenthixol decanoate in comparison with placebo, oral antipsychotics and other depot neuroleptic preparations for people with schizophrenia and other severe mental illnesses, in terms of clinical, social and economic outcomes. SEARCH STRATEGY: Relevant trials were identified by searching Biological Abstracts (1982-1998), Cochrane Library (Issue 2, 1998), Cochrane Schizophrenia Group's Register (December 1998), EMBASE (1980-1998), MEDLINE (1966-1998) and PsycLIT (1974-1998). The references of all identified trials were inspected for more studies and the first author of each included trial and relevant pharmaceutical companies were contacted. SELECTION CRITERIA: All randomised controlled trials that focused on people with schizophrenia or other similar psychotic disorders where flupenthixol decanoate had been compared to placebo or other antipsychotic drugs. All clinically relevant outcomes were sought. DATA COLLECTION AND ANALYSIS: Studies were reliably selected, quality rated and data extracted. For dichotomous data Peto odds ratios (OR) with 95% confidence intervals (CI) were estimated. Where possible, the number needed to treat statistic (NNT) was also calculated. Analysis was by intention-to-treat. Normal continuous data were summated using the weighted mean difference (WMD). Scale data were presented only for those tools that had attained pre-specified levels of quality. MAIN RESULTS: No trials compared flupenthixol decanoate to placebo. One small study compared flupenthixol decanoate with an oral antipsychotic (penfluridol). There were no clear differences between the two preparations. When flupenthixol decanoate was compared to other depot preparations, there were no differences between depots for outcomes such as death, global impression, relapse (OR 1.16 CI 0.7-1.9) or leaving the study early (OR 1.00 CI 0.6-1.7). Two small studies suggest that flupenthixol decanoate is responsible for less movement disorders than other depot antipsychotic drugs (OR 0.23 CI 0.08-0.7, NNT 5). This finding did not hold for specific side effects, such as tremor (OR 1.2 CI 0.3-4) and tardive dyskinesia (OR 1.60 CI 0.4-6). Two trials comparing high doses of flupenthixol decanoate to the standard approximately 40mg per injection reported no significant difference for the outcome of relapse (OR 0.32 CI 0.09-1.2). One small (n=59) trial comparing a very low dose of flupenthixol decanoate ( approximately 6 mg/IM) to a very low dose approximately 9 mg per injection also reported no difference in relapse rates (OR 0.3 CI 0.1-1.1). REVIEWER'S CONCLUSIONS: From the data reported in clinical trials, it would be understandable if those suffering from schizophrenia, who are willing to take flupenthixol decanoate, would request the standard dose rather than the high dose. In the current state of evidence, there is nothing to choose between flupenthixol decanoate and other depot antipsychotics. The choice of which depot to use must therefore be based on clinical judgement and the preferences of people with schizophrenia and their carers. Managers and policy makers should expect better data than the research community has provided thus far. This review highlighted the need for large, well-designed and reported randomised clinical trials to address the effects of flupenthixol decanoate, in particular when compared to oral antipsychotics. Future studies should also consider hospital and service outcomes, satisfaction with care and record economic data.

Intermanual coordination in relation to different clinical subgroups in right-handed patients with schizophrenic and other psychotic disorders.

BACKGROUND: Interhemispheric transfer in psychotic patients is still a controversial issue. Based on the fact that intermanual coordination is associated with interhemispheric transfer, scores in intermanual coordination were investigated in patients with psychotic disorders. METHOD: Intermanual coordination was assessed by alternating finger-tapping in 73 adult right-handed in-patients with schizophrenic and other psychotic disorders and was compared with that of 75 healthy right-handed controls. Five clinical subgroups of patients whose diagnoses were based on the DSM-IV classification were specified. RESULTS: Scores in intermanual coordination in the patients as a whole did not differ from those of the controls. When, however, different clinical subgroups and various manifestations of symptoms were taken into consideration, the scores among those subgroups differed significantly. For instance, patients with residual schizophrenia and chronic symptoms showed lower values in intermanual coordination than did patients with schizoaffective disorders and prevailing acute symptoms. CONCLUSIONS: The assessment of intermanual coordination may provide new insights into the functional coupling of both hemispheres in schizophrenic and other psychotic disorders and may be of a certain prognostic value. Because of its non-invasive, fast and simple application, this approach is thought to be especially suited for investigating acute psychiatric in-patients.

[Treatment of depression secondary to psychotic disorders].

More than 25% patients suffering from psychotic disorders would show during their evolution some depressive disorders. More than 10% would die from suicide. Secondary depressions following psychotic disorders are heterogeneous. They have to be specified in order to assess therapeutics including biological psychological and socio-environmental approaches. Treatment of depressive disorders correlated to psychotic symptomatology, being mood congruent or not, is the same as characterized depression. However it is preferred to associate antidepressant and neuroleptic or electroconvulsivotherapy. Depressive symptomatology in psychotic disorders is mostly secondary due to delusion, negative or even deficit symptomatology. It often requires to adapt individual choice and posology of antipsychotic treatment. Depressive states in "post-psychotic" phase, secondary to acute phase or in the evolution of chronic psychosis, may be for some of them linked to neuroleptic treatment side effects: in this case, posology and indication have to be discussed. In other cases, it may be indicated to prescribe antidepressant or even electroconvulsivotherapy after having considered the existence of psycho-dynamic reorganization and the need of psychotherapic, social or institutional support. The existence of depressive disorders in the evolution of psychosis leads to ask about their significance: psychological reaction, comorbidity of two distinct pathologies, evidence of continuum between affective disorders and schizophrenia.

Acute and transient psychotic disorder: comorbidity with personality disorder.

A study sample of 51 patients with acute and transient psychotic disorder (ATPD) (ICD-10) is presented. The findings suggest that, in hospital settings, ATPD is a non-frequent condition with onset in early adult life and most often associated with female sex, good premorbid social functioning and no or minor/moderate psychosocial stressors. The DSM-IV criteria distribute the patients into three diagnostic categories: schizophreniform disorder (41%), brief psychotic disorder (33%) and psychotic disorder not otherwise classified (25%). A high prevalence (63%) of personality disorders (PD) is revealed after recovery from the psychotic episode. The ATPD is not related to any specific PD, and in a substantial minority (37%) of cases no PD is found. The unspecified category is by far the most frequent PD in patients with ATPD. The sample will be followed up and reassessed.

Duloxetine treatment of major depressive episodes in the course of psychotic disorders.

During the course of psychotic disorders, patients often suffer from intercurrent major depressive episodes (MDEs), and suicides frequently occur. This constellation challenges further improvements in psychopharmacological therapy. The antidepressant duloxetine was recently introduced as a novel reuptake inhibitor of serotonin and noradrenaline. We provide the first reports on duloxetine treatment of MDEs in the course of psychotic disorders. In two cases this substance was successfully involved as an add-on to antipsychotic treatment consisting of clozapine or amisulpride. We achieved a response of the MDEs, as reflected by psychopathological rating scales. A significant rise in the clozapine serum level was detected, most likely because of pharmacokinetic interactions. Overall, the application of duloxetine was well tolerated; therefore, further investigations in prospective studies seem to be recommendable.

Diagnostic challenges in children and adolescents with psychotic disorders.

The diagnosis of psychotic disorders in children and adolescents is often complex and challenging. The symptomatic overlap between different psychotic conditions and other emotional, behavioral, and developmental disorders has led to high rates of misdiagnosis, especially at time of onset. The clinical expression and progression of diagnosable disorders are affected by maturational processes. Thus, psychotic illnesses in pediatric patients may vary from adult presentations because of developmental factors. Establishing a specific diagnosis is difficult when the differential diagnosis comprises disorders that share common symptoms and are frequently comorbid. The clinical assessment depends as much on input from parents and teachers as from the patients themselves, and there may be conflict between these different perceptions. This article reviews recent research and current concepts relating to diagnostic challenges in pediatric psychiatry.

Stress, the hippocampus and the hypothalamic-pituitary-adrenal axis: implications for the development of psychotic disorders.

OBJECTIVE: The experience of stress is commonly implicated in models of the onset of psychotic disorders. However, prospective studies investigating associations between biological markers of stress and the emergence of psychotic disorders are limited and inconclusive. One biological system proposed as the link between the psychological experience of stress and the development of psychosis is the Hypothalamic-Pituitary-Adrenal (HPA) axis. This paper summarizes and discusses evidence supporting a role for HPA-axis dysfunction in the early phase of schizophrenia and related disorders. METHOD: A selective review of psychiatric and psychological research on stress, coping, HPA-axis, the hippocampus and psychotic disorders was performed, with a particular focus on the relationship between HPA-axis dysfunction and the onset of psychotic disorders. RESULTS: Individual strands of past research have suggested that the HPA-axis is dysfunctional in at least some individuals with established psychotic disorders; that the hippocampus is an area of the brain that appears to be implicated in the onset and maintenance of psychotic disorders; and that an increase in the experience of stress precedes the onset of a psychotic episode in some individuals. Models of the onset and maintenance of psychotic disorders that link these individual strands of research and strategies for examining these models are proposed in this paper. CONCLUSIONS: The current literature provides some evidence that the onset of psychotic disorders may be associated with a higher rate of stress and changes to the hippocampus. It is suggested that future research should investigate whether a relationship exists between psychological stress, HPA-axis functioning and the hippocampus in the onset of these disorders. Longitudinal assessment of these factors in young people at 'ultra' high risk of psychosis and first-episode psychosis cohorts may enhance understanding of the possible interaction between them in the early phases of illness.

Effect of video self-observation on development of insight in psychotic disorders.

Many patients with psychotic disorders lack awareness of being ill. This often presents a serious impediment to treatment compliance. We hypothesized that exposing partially remitted patients to videotapes of themselves, made while they were acutely psychotic, might increase their insight into the nature of their illness. Eighteen acutely psychotic inpatients were assigned randomly to a control or experimental group and interviewed on videotape 24 to 48 hours after admission, using scales that measure insight (Insight and Treatment Attitudes Questionnaire [ITAQ]) and psychopathology (Brief Psychiatric Rating Scale [BPRS]). One to six weeks later, when judged to be significantly improved, subjects were shown either a videotape of their initial interview (experimental group) or a placebo videotape (control group) and then reinterviewed 24 to 48 hours later on videotape, using the BPRS and ITAQ scales. Evaluation of initial and final ITAQ and BPRS scores revealed significantly greater improvement in insight scores and in delusionality in the experimental group. However, no significant difference in overall psychopathology was seen for the two groups. These results suggest that exposure of hospitalized patients to videotapes of their own psychotic behavior may be a cost-effective therapeutic tool for developing personal insight into psychotic illness.

A critique of the Diagnostic Criteria for Psychiatric Disorders for Use with Adults with Learning Disabilities/Mental Retardation (DC-LD) chapter on non-affective psychotic disorders.

BACKGROUND: There has been a longstanding interest in the study of psychotic disorders in adults with intellectual disability. The DC-LD chapter for non-affective psychotic disorders provides operationalised criteria for use with this population. METHODS: A detailed, structured review of the literature was carried out. Relevant papers were reviewed to provide a framework for a critique of the DC-LD criteria. RESULTS: Most of the research literature focuses on psychotic disorders in adults with mild intellectural disability and suggests that this group experience clinical symptoms similar to those experienced by adults with average abilities. Although the DC-LD criteria for non-affective psychotic disorders are derived from the ICD-10 equivalent categories they are broader than other classification systems, which may affect their reliability, validity and utility. CONCLUSIONS: At this stage, it is important that the DC-LD criteria are used alongside established systems to gather information about their use for clinical and research purposes.

Impact of panic attacks on rehabilitation and quality of life among persons with severe psychotic disorders.

OBJECTIVE: The study evaluated data from a sample of persons with severe psychotic disorders to determine whether those with and without comorbid panic attacks differed in rates of comorbidity of other psychiatric disorders, in quality of life, and in rehabilitation outcomes. METHODS: A total of 120 individuals with psychotic disorders were assessed with the Center for Epidemiologic Studies-Depression scale, the Structured Clinical Interview for DSM-III-R, the General Health Questionnaire, the Global Assessment of Functioning scale, and several quality-of-life measures at baseline and four and a half months after they had participated in a social rehabilitation program. Multivariate analyses of variance and Pearson's chi square tests were used to compare baseline and follow-up scores between individuals who did and did not have panic attacks. RESULTS: Eighteen (15 percent) of the participants who had severe psychotic disorders also had panic attacks. Participants with this type of comorbidity had significantly higher rates of major depressive disorder, specific phobia, sedative abuse, polysubstance abuse, other substance abuse, and anorexia nervosa than participants who did not have panic attacks. Participants who had panic attacks also had poorer rehabilitative outcomes and poorer quality of life at baseline and at follow-up than participants who did not have panic attacks. CONCLUSIONS: These data are the first to show that comorbid panic attacks are associated with poorer rehabilitative outcomes and poorer quality of life among individuals with severe psychotic disorders than among those who have psychotic disorders without panic attacks. Panic attacks may be a valuable prognostic indicator among persons with psychotic disorders and may have implications for treatment and rehabilitation.

What is schizophrenic in acute and transient psychotic disorder?

Acute and transient psychotic disorder (ATPD) is supposed to differ from schizophrenia, but little research has been done on the subject. In a prospective longitudinal case control study we compared all inpatients with ATPD (ICD-10 F23) treated at Halle University Hospital during a 5-year period with matched controls with "positive" schizophrenia (PS) and with mentally healthy controls. Followup investigations were performed at a mean of 2.2 years after the index episode or 8.2 years after the first episode. Female preponderance in ATPD was marked (78.6%). ATPD and PS patients were similar to each other (but different from healthy controls) in the prevalence of a "broken home" situation and a family history for mental disorders. Compared with PS patients, ATPD patients showed better premorbid social adaptation, and they more often displayed rapidly changing symptoms in the index episode and a negative life event preceding the episode. Despite comparable relapse rates, at followup ATPD patients showed better social adaptation, less psychological impairment, and better global functioning than PS patients. These data support the delineation of ATPD from schizophrenia.

The concept of cycloid psychotic disorder.

The concept of cycloid psychosis or cycloid psychotic disorder has been used in the European psychiatric literature for almost half a century. However, it has now for the first time been comprised into the 10th revision of the World Health Organization's International Classification of Diseases (ICD-10) that is currently in the phase of field trials. In this article evidence is presented that supports the independence of cycloid psychotic disorder from other major psychotic disorders. In particular, evidence is presented in favour of the clinical and predictive validity of the cycloid psychosis construct. Issues related to treatment are discussed and suggestions for future research are given.

Biological studies of DSM-III psychotic disorders. I. Platelet measures and apomorphine-induced growth hormone response.

The relationship between DSM-III schizophrenia, major affective disorders, and the psychotic disorders not elsewhere classified (PDNEC) can be explored through studies which attempt to determine whether these disorders can be differentiated from one another and normal controls by biological measures. Preliminary results of an ongoing project which utilizes measures of blood platelet monoamine oxidase (MAO), serotonin (5-HT) uptake, and 5-HT content, and the apomorphine-induced increase in growth hormone (GH) to accomplish these goals are reported here. DSM-III major affective disorders (bipolar disorder and major depression) can be differentiated from normal controls by the V max of platelet 5-HT. Platelet 5-HT V max of bipolar disorder, depressed type, is significantly different from that of schizophrenia and PDNEC. Elevated platelet 5-HT content is present in black schizophrenic patients compared to black normal controls. Platelet MAO was increased in a small group of schizophreniform female patients. There was no difference in the apomorphine-induced GH response between any of the diagnostic groups. If confirmed in a larger series of patients, these results tend to identify the PDNEC more closely with schizophrenia than the major affective disorders.

Clozapine and obsessions in patients with recent-onset schizophrenia and other psychotic disorders.

BACKGROUND: The increase or emergence of obsessions was compared in young patients with recent-onset schizophrenia or other psychotic disorders taking clozapine and other antipsychotic drugs. METHOD: We conducted a retrospective cohort study. Subjects were 121 consecutively admitted patients diagnosed with DSM-III-R schizophrenia, schizoaffective disorder, schizophreniform disorder, or psychotic disorder not otherwise specified. Obsessions were diagnosed according to DSM-IV criteria. RESULTS: More clozapine-treated subjects (20.6%) than subjects treated with other antipsychotic drugs (1.3%) experienced an emergence or increase of obsessions (p<.01). CONCLUSION: Use of clozapine is associated with the emergence or increase of obsessions in early-phase schizophrenia.

Patterns of service use among persons with schizophrenia and other psychotic disorders.

OBJECTIVE: This study assessed 12-month service use patterns among people with psychotic disorders and sought to identify determinants of service use. METHODS: As part of a large two-phase Australian study of psychotic disorders, structured interviews were conducted with a stratified random sample of adults who screened positive for psychosis. Demographic characteristics, social functioning, symptoms, mental health diagnoses, and use of psychiatric and nonpsychiatric services were assessed. Data were analyzed for 858 persons who had an ICD-10 diagnosis of a psychotic disorder and who had been hospitalized for less than six months during the previous year. RESULTS: People with psychotic disorders had high levels of use of health services, both in absolute terms and relative to people with nonpsychotic disorders. Those with psychotic disorders were estimated to have an average of one contact with health services per week. Use of psychiatric inpatient services was associated with parenthood, higher symptom levels, recent attempts at suicide or self-harm, personal disability, medication status, and frequency of alcohol consumption. Services provided by general practitioners (family physicians) were more likely to be obtained by older people, women, people with greater availability of friends, those with fewer negative symptoms, and those whose service needs were unmet by other sources. People who were high users of health services also reported having more contact with a range of non-health agencies. CONCLUSIONS: The predictors of service use accounted for small proportions of the variance in overall use of health services. The role of general practitioners in providing and monitoring treatment programs and other psychosocial interventions needs to be acknowledged and enhanced.

Occurrence and clinical correlates of psychiatric comorbidity in patients with psychotic disorders.

BACKGROUND: The aim of this study was to explore patterns and clinical correlates of psychiatric comorbidity in patients with schizophrenia spectrum disorders and mood spectrum disorders with psychotic features. METHOD: Ninety-six consecutively hospitalized patients with current psychotic symptoms were recruited and included in this study. Index episode psychotic diagnosis and psychiatric comorbidity were assessed using the Structured Clinical Interview for DSM-III-R-Patient Version (SCID-P). Psychopathology was assessed by the SCID-P, Brief Psychiatric Rating Scale, Scale for the Assessment of Negative Symptoms, and Hopkins Symptom Checklist. Awareness of illness was assessed with the Scale to Assess Unawareness of Mental Disorders. RESULTS: The total lifetime prevalence of psychiatric comorbidity in the entire cohort was 57.3% (58.1% in schizophrenia spectrum disorders and 56.9% in mood spectrum psychoses). Overall, panic disorder (24%), obsessive-compulsive disorder (24%), social phobia (17.7%), substance abuse (11.5%), alcohol abuse (10.4%), and simple phobia (7.3%) were the most frequent comorbidities. Within the group of mood spectrum disorders, negative symptoms were found to be more frequent among patients with psychiatric comorbidity than among those without comorbidity, while such a difference was not detected within the group of schizophrenia spectrum disorders. Social phobia, substance abuse disorder, and panic disorder comorbidity showed the greatest association with psychotic features. An association between earlier age at first hospitalization and comorbidity was found only in patients with unipolar psychotic depression. Patient self-reported psychopathology was more severe in schizophrenia spectrum patients with comorbidity than in those without, while such a difference was less pronounced in mood spectrum psychoses. CONCLUSION: These findings suggest that psychiatric comorbidity is a relevant phenomenon in psychoses and is likely to negatively affect the phenomenology of psychotic illness. Further studies in larger psychotic populations are needed to gain more insight into the clinical and therapeutic implications of psychiatric comorbidity in psychoses.
