Altered emotional experiences attributed to antipsychotic medications - A potential link with estimated dopamine D2 receptor occupancy. Psychiatry Res 2016; 236:9-14. [PMID: 26791397 DOI: 10.1016/j.psychres.2016.01.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2015] [Revised: 10/09/2015] [Accepted: 01/05/2016] [Indexed: 12/31/2022]
Abstract
Altered emotional experiences in response to antipsychotics may increase the burden of disease in patients with schizophrenia. In a large cross-sectional study, patients with schizophrenia completed the Subjects Reaction to Antipsychotics questionnaire (SRA) to assess whether they attributed altered emotional experiences (flattened affect or depressive symptoms) to their antipsychotics. Association with antipsychotic D2 receptor affinity and occupancy was examined using logistic regression. We compared antipsychotic-attributed emotional experiences between patients using antipsychotic monotherapy and combination therapy. Of the 1298 included patients, 23% attributed flattened affect to their antipsychotics and 16% attributed depressive symptoms to their antipsychotics, based on the SRA. No differences were observed between antipsychotics in patients on monotherapy. We discuss that within these patients' relatively low dose range, altered emotional experiences did not appear to relate to the level of D2 receptor affinity of antipsychotic monotherapy. Patients using antipsychotic combination therapy (22%) were more likely to attribute depressive symptoms to their antipsychotics than patients using antipsychotic monotherapy (OR [95%CI]=1.443 [1.033-2.015]); possibly due to higher D2 receptor occupancies as estimated by dose equivalents.

Differential stigmatizing attitudes of healthcare professionals towards psychiatry and patients with mental health problems: something to worry about? A pilot study. Soc Psychiatry Psychiatr Epidemiol 2015; 50:299-306. [PMID: 25123701 DOI: 10.1007/s00127-014-0931-z] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2014] [Accepted: 07/16/2014] [Indexed: 10/24/2022]
Abstract
PURPOSE This study compares stigmatizing attitudes of different healthcare professionals towards psychiatry and patients with mental health problems. METHODS The Mental Illness Clinicians Attitude (MICA) questionnaire is used to assess stigmatizing attitudes in three groups: general practitioners (GPs, n = 55), mental healthcare professionals (MHCs, n = 67) and forensic psychiatric professionals (FPs, n = 53). RESULTS A modest positive attitude towards psychiatry was found in the three groups (n = 176). Significant differences were found on the total MICA-score (p < 0.001). GPs scored significantly higher than the FPs and the latter scored significantly higher than the MHCs on all factors of the MICA. Most stigmatizing attitudes were found on professionals' views of health/social care field and mental illness and disclosure. Personal and work experience did not influence stigmatizing attitudes. CONCLUSIONS Although all three groups have a relatively positive attitude using the MICA, there is room for improvement. Bias toward socially acceptable answers cannot be ruled out. Patients' view on stigmatizing attitudes of professionals may be a next step in stigma research in professionals.

Psychometric properties of the self-report version of the Quick Inventory of Depressive Symptoms (QIDS-SR₁₆) questionnaire in patients with schizophrenia. BMC Psychiatry 2014; 14:247. [PMID: 25178310 PMCID: PMC4159524 DOI: 10.1186/s12888-014-0247-2] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2013] [Accepted: 08/19/2014] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND Self-report instruments for the assessment of depressive symptoms in patients with psychotic disorders are scarce. The Quick Inventory of Depressive Symptoms (QIDS-SR16) may be a useful self-report instrument, but has received little attention in this field. This paper aimed to test the psychometric properties of the QIDS-SR16 questionnaire in patients with a psychotic disorder. METHODS Patients diagnosed with a psychotic disorder from health care institutions in The Netherlands were included in the study. Depressive symptoms were assessed with the QIDS-SR16 and the Calgary Depression Scale for Schizophrenia (CDSS). Psychotic symptoms were assessed with the Positive and Negative Syndrome Scale (PANSS) and extrapyramidal symptoms (EPS) with three EPS rating scales. Spearman's correlation coefficients were used to compare the total score of the QIDS-SR16 with the total scores of the CDSS, PANSS-subscales and EPS rating scales. RESULTS In a sample of 621 patients with psychotic disorders, the QIDS-SR16 showed good internal consistency (α = 0.87). The QIDS-SR16 correlated moderately with the CDSS (r = 0.44) and the PANSS subscale for emotional distress (r = 0.47). The QIDS-SR16 showed weak correlation with the PANSS subscale for negative symptoms (r = 0.28) and minimal correlation with EPS rating scales (r = 0.09-0.16). CONCLUSIONS The QIDS-SR16 may reliably assess depressive symptoms in patients with psychotic disorders, but its concurrent validity with the CDSS was rather poor in this population. We would recommend developing a new self-report questionnaire for the assessment of depressive symptoms in patients with psychotic disorders.

A brief version of the Subjects' Response to Antipsychotics questionnaire to evaluate treatment effects. Schizophr Res 2013; 147:175-180. [PMID: 23561295 DOI: 10.1016/j.schres.2013.02.027] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2012] [Revised: 01/31/2013] [Accepted: 02/20/2013] [Indexed: 10/27/2022]
Abstract
BACKGROUND Monitoring patients' experiences with antipsychotics may help to improve medication adherence and outcome. We aimed to develop a shorter version of a comprehensive 74-item self-report questionnaire suitable for routine monitoring of desired and undesired effects of antipsychotics. METHODS Included were patients with psychotic disorders from seven mental health care organizations in The Netherlands, using antipsychotic medication, who completed the Subjects' Response to Antipsychotics (SRA-74). Exploratory factor analysis (EFA) and similarity analysis based on mutual information were used to identify the latent factor structure of the SRA. Items were reduced according to their metric properties and clinical relevance upon consensus by an expert panel, using a Delphi procedure of three rounds. We determined the internal consistency of the shorter version using Cronbach's alpha. RESULTS SRA data of N=1478 patients (mean age of 40 years, 31% females) were eligible for analysis. EFA extracted thirteen factors from the SRA-74, including four factors for desired effects (e.g. recovery of psychosis, cognition and social functioning) and nine factors for undesired effects (e.g. weight gain, flattened affect and increased sleep). Based on this solution 12 items were eliminated for statistical reasons. The expert panel eliminated another 28 items with redundant content, resulting in a 34-item version. The SRA-34 includes 10 desired and 24 clinically relevant undesired effects. Both the subscales for desired and undesired effects have a Cronbach's alpha coefficient of 0.82. CONCLUSIONS The SRA-34 can be used to evaluate desired and undesired effects of antipsychotics in routine clinical practice and research.

Weight change by baseline BMI from three-year observational data: findings from the Worldwide Schizophrenia Outpatient Health Outcomes Database. J Psychopharmacol 2013; 27:358-65. [PMID: 23343595 DOI: 10.1177/0269881112473789] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/01/2023]
Abstract
The aim was to explore weight and body mass index (BMI) changes by baseline BMI in patients completing three years of monotherapy with various first- and second-generation antipsychotics in a large cohort in a post hoc analysis of three-year observational data. Data were analyzed by antipsychotic and three baseline BMI bands: underweight/normal weight (BMI <25 kg/m²), overweight (25-30 kg/m²) and obese (>30 kg/m²). Baseline BMI was associated with subsequent weight change irrespective of the antipsychotic given. Specifically, a smaller proportion of patients gained ≥7% baseline bodyweight, and a greater proportion of patients lost ≥7% baseline bodyweight with increasing baseline BMI. For olanzapine (the antipsychotic associated with highest mean weight gain in the total drug cohort), the percentage of patients gaining ≥7% baseline weight was 45% (95% CI: 43-48) in the underweight/normal weight BMI cohort and 20% (95% CI: 15-27) in the obese BMI cohort; 7% (95% CI: 6-8) of the underweight/normal cohort and 19% (95% CI: 13-27) of the obese cohort lost ≥7% baseline weight. BMI has an association with the likelihood of weight gain or loss and should be considered in analyses of antipsychotic weight change.

A systematic review of instruments to measure depressive symptoms in patients with schizophrenia. J Affect Disord 2012; 140:38-47. [PMID: 22099566 DOI: 10.1016/j.jad.2011.10.014] [Citation(s) in RCA: 113] [Impact Index Per Article: 9.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2011] [Revised: 10/11/2011] [Accepted: 10/11/2011] [Indexed: 10/15/2022]
Abstract
BACKGROUND Depressive symptoms require accurate recognition and monitoring in clinical practice of patients with schizophrenia. Depression instruments developed for use in depressed patients may not discriminate depressive symptoms from negative psychotic symptoms. OBJECTIVE We reviewed depression instruments on their reliability and validity in patients with schizophrenia. METHODOLOGY A systematic literature search was carried out in three electronic databases. Psychometric properties were extracted for those instruments of which reliability, divergent, concurrent and predictive validity were reported in one or more publications. RESULTS Forty-eight publications described the reliability and validity of six depression instruments in patients with schizophrenia. The only self-report was the Beck Depression Inventory (BDI). The Brief Psychiatric Rating Scale-Depression subscale (BPRS-D), Positive and Negative Syndrome Scale-Depression subscale (PANSS-D), Hamilton Rating Scale for Depression (HAMD), Montgomery Asberg Depression Rating Scale (MADRS) and Calgary Depression Scale for Schizophrenia (CDSS) were clinician rated. All instruments were reliable for the measurement of depressive symptoms in patients with schizophrenia. The CDSS most accurately differentiated depressive symptoms from other symptoms of schizophrenia (divergent validity), correlated well with other depression instruments (concurrent validity), and was least likely to miss cases of depression or misdiagnose depression (predictive validity). CONCLUSIONS We would recommend to use the CDSS for the measurement of depressive symptoms in research and in daily clinical practice of patients with schizophrenia. A valid self-report instrument is to be developed for the use in clinical practice.

Abstract
BACKGROUND Weight change data from randomized clinical trials are often of limited duration and trials do not always report a full range of clinically relevant categorical end points. METHOD We conducted a post hoc analysis of data from the observational Worldwide Schizophrenia Outpatient Health Outcomes database (2000-2005) on weight change in 4,626 patients completing 3 years of antipsychotic monotherapy with amisulpride, clozapine, olanzapine, quetiapine, risperidone, and oral and depot first-generation antipsychotics (FGAs). Reported outcomes included mean and categorical weight changes and the trajectories of different measures of weight change. RESULTS Mean weight gain was lowest with amisulpride (1.8 kg; 95% CI, 0.2-3.3) and highest with olanzapine (4.2 kg; 95% CI, 3.9-4.5). Weight change for all antipsychotics was most rapid during the first 6 months; subsequent weight change was slower but did not plateau. All drugs showed considerable individual variation in weight change. The proportion losing ≥7% of their baseline bodyweight was highest with quetiapine (10%; 95% CI, 7%-16%) and lowest with depot FGAs (5%; 95% CI, 3%-10%). Between 7% and 15% of patients moved into an overweight or obese body mass index (kg/m2)category (≥25). CONCLUSIONS The degree of weight gain varied between antipsychotics. All antipsychotics were associated with significant (≥7%) weight loss and gain from baseline. The mean rate of weight gain was maximal during the first 6 months but continued over 3 years without a plateau in this specific cohort. Patients should receive regular monitoring of weight throughout treatment.

Abstract
BACKGROUND Antidepressants are frequently prescribed in patients with psychotic disorders, but little is known about their effects in routine clinical practice. The objective was to investigate the prescribing patterns of antidepressants in relation to the course of depressive symptoms in patients with psychotic disorders. METHODS A cohort of 214 Dutch patients with psychotic disorders received two assessments of somatic and psychiatric health, including a clinician-rated screening for depressive symptoms, as part of annual routine outcome monitoring. RESULTS Depressive symptoms were prevalent among 43% (93) of the patients. Antidepressants were prescribed for 40% (86) of the patients and the majority 83% (71) continued this therapy after one year. Multivariable analysis showed that patients with more severe psychopathology had a higher risk to develop depressive symptoms the following year (OR [95% CI]=0.953 [0.912-0.995]). For patients with depressive symptoms at baseline, polypharmacy was a potential risk factor to keep having depressive symptoms (OR [95% CI]=1.593 [1.123-2.261]). Antidepressant use was not an independent predictor in both analyses. CONCLUSIONS Routine outcome monitoring in patients with psychotic disorders revealed a high prevalence of depressive symptoms. Antidepressants were frequently prescribed and continued in routine clinical practice.

Abstract
BACKGROUND Patients suffering from psychotic disorders have an increased risk of comorbid somatic diseases such as cardiovascular disorders and diabetes mellitus. Doctor-related factors, such as unfamiliarity with these patients, as well as patient-related factors, such as cognitive disturbance and negative symptoms, contribute to suboptimal health care for these patients.General practitioners (GPs) could play a key role in diagnosing and treating this somatic comorbidity as in the Netherlands, almost all residents are registered at a general practice. This study aims to find out whether there are any differences between the levels of health care provided by GPs to patients with psychotic disorders, compared to other types of patients. METHODS A cohort of patients with an ICPC code of psychosis and two matched control groups, one consisting of patients with other mental problems and the other one of patients without any mental problems, were followed over a period of 5 years. RESULTS Patients with psychotic disorders (N = 734) contacted the GP practice more often than patients in the control groups. These patients, both adults (p = 0.051) and the elderly (p < 0.005), received more home visits from their GPs. In the adult group (16 to 65 years old inclusive), the number of consultations was significantly higher among both psychosis patients and the group of patients with other mental problems (p < 0.0005). The number of telephone consultations was significantly higher in both age categories, adult group (p < 0.0005), and > 65 years old (p = 0.007). With regard to chronic illnesses, elderly psychosis patients had fewer contacts related to cardiovascular diseases or chronic lung diseases. CONCLUSION Patients with psychotic disorders contact the GP practice more frequently than other types of patients. Adult psychosis patients with diabetes mellitus, cardiovascular diseases or chronic lung diseases receive the same amount of health care for these diseases as other primary care patients. The finding that older patients with psychotic disorders are diagnosed with cardiovascular diseases and obstructive lung diseases less frequently than other types of elderly patients requires further study.

Abstract
Although it has been suggested that second-generation antipsychotics (SGA) may reduce the rate of prevalent tardive dyskinesia (TD), little is known about the incidence and outcome of TD in those exposed exclusively to SGA. The incidence and subsequent persistence of TD and extrapyramidal symptoms (EPS) was calculated in a cohort of patients with schizophrenia treated predominantly with SGA. This cohort of more than 10,000 patients with schizophrenia was seen six times over a period of two years. Dichotomous measures of EPS and TD were used to calculate the yearly incidence rates of TD and EPS as well as their subsequent cumulative persistence rate in a subset of 9104 and 6285 patients at risk for TD and EPS, respectively. Of 9104 individuals who did not present with TD at baseline, 138 developed TD, yielding a TD incidence rate of 0.74% (95% CI: 0.62, 0.87) and a subsequent cumulative persistence rate of 80%. Of 6285 individuals without EPS at baseline, 464 developed EPS yielding an incidence rate of 3.7% (95% CI: 3.4, 4.0) and a subsequent cumulative persistence rate of 82%. Incidence rates of TD and EPS may be low in the SGA era. However, once emerged, these disorders prove persistent, suggesting strong moderators effects of underlying predisposing factors.

Abstract
BACKGROUND Negative symptoms in patients with schizophrenia predict a worse social outcome. The treatment options for negative symptoms are extremely limited. Various treatment strategies have been studied in which several types of medication were added to antipsychotics in order to alleviate negative symptoms. AIM To review the types of medication that have been used to supplement antipsychotic treatment in order to alleviate negative symptoms in patients with schizophrenia. METHOD By means of PubMed we were able to perform a systematic review of all randomised controlled trials and relevant meta-analyses published up to and including May 2009. RESULTS The pharmacological mechanisms that were studied in connection with the treatment of negative symptoms were as follows: the modulation of the glutamate system, the modulation of the serotonergic system, the histaminergic system and the dopaminergic system and the influencing by means of antioxidants and hormones. Despite all the methodological problems the modulation of the glutamate system and the blocking of serotonin 5-HT-3/2a receptors may be able to bring about a limited reduction of negative symptoms. The therapeutic results of the pharmacological treatments studied which may be effective is only moderate. CONCLUSION For the time being the pharmacological addition strategies do not lead us to recommend their use in current clinical practice but they can certainly serve as a basis for further research. medication, negative symptoms, schizophrenia.

Abstract
BACKGROUND Routine outcome monitoring (ROM) means the assessment of the patient's condition on a routine basis using instruments. So far there is no consensus about which instruments should be used for ROM with severely mentally ill patients (ROM-SMI). AIM To reach a consensus about instruments for ROM-SMI in the Netherlands and Belgium and to create possibilities for comparison of ROM data. METHOD This article discusses the consensus document of the National Remission Working Group for ROM in patients with smi and covers the following topics: reasons for ROM-SMI, domains for ROM-SMI and appropriate instruments, logistics and analyses of the data. RESULTS Patients with SMI have problems in several domains. These can be assessed by collecting information about psychiatric symptoms, addiction, somatic problems, general functioning, needs, quality of life and care satisfaction. Potential instruments for ROM-SMI are short, valid, reliable and assess several domains, taking the patient's perspective into account, and have been used in national and international research. The working group advises institutions to choose from a limited set of instruments. After the scores have been aggregated and standardised, comparisons can be drawn. ROM-SMI data can be interpreted more meaningfully, if outcome data are supplemented with data regarding patient characteristics and the treatment interventions already applied. CONCLUSION It should be possible to reach a consensus about instruments for ROM-SMI and the way in which they should be used. The use of identical instruments will lead to improvements in mental health care and create possibilities for comparison (benchmarking) and research.

Abstract
BACKGROUND Neuroimaging findings implicate bilateral superior temporal regions in the genesis of auditory-verbal hallucinations (AVH). This study aimed to investigate whether 1 Hz repetitive transcranial magnetic stimulation (rTMS) of the bilateral temporo-parietal region would lead to increased effectiveness in the management of AVH, compared to left rTMS or placebo. METHODS 38 patients with schizophrenia (DSM-IV) and medication-resistant AVH were randomly assigned to 1 Hz rTMS treatment of the left temporo-parietal region, bilateral temporo-parietal regions, or placebo. Stimulation was conducted over 6 days, twice daily for 20 min, at 90% of the motor threshold. Effect measures included the Auditory Hallucination Rating Scale (AHRS), Positive and Negative Affect Scale (PANAS), and a score for hallucination severity obtained from the Positive and Negative Syndrome Scale (PANSS). RESULTS All groups showed some improvement on the total AHRS. Hallucination frequency was significantly reduced in the left rTMS group only. The bilateral rTMS group demonstrated the most remarkable reduction in self-reported affective responsiveness to AVH. A modest, but significant decrease on the PANSS hallucination item was observed in the combined rTMS treatment group, whereas no change occurred in the placebo group. The left rTMS group showed a significant reduction on the general psychopathology subscale. CONCLUSION Compared to bilateral or sham stimulation, rTMS of the left temporo-parietal region appears most effective in reducing auditory hallucinations, and additionally may have an effect on general psychopathology. Placebo effects should however not be ruled out, since sham stimulation also led to improvement on a number of AVH parameters.

Abstract
Cross-sectional studies showed a high prevalence of metabolic syndrome in patients with schizophrenia.This study aimed to identify the incidence of metabolic syndrome and its reversal in a non-preselected cohort of chronic psychotic patients in routine practice in one year follow-up and to find variables to describe development and reversal of metabolic syndrome. This cohort study was conducted as part of a disease management program and patients were included if they had two complete assessments in a one year follow-up. We conducted two logistic regressions to find variables to describe the development of metabolic syndrome and the reversal of metabolic syndrome. At the time of the first assessment 35% (n=92) of the 260 included patients had metabolic syndrome. Within one year 21 patients developed metabolic syndrome and 30 patients had it reversed. This was an incidence of 13% (21/168) and a reversal of 33% (30/92). Smoking, family history of cardiovascular diseases, and duration of disease >6 years was associated with a higher risk of developing metabolic syndrome as well as abdominal obesity and dyslipidemia. Patients with abdominal obesity had a smaller chance of reversing metabolic syndrome. Other variables included in the logistic regression such as receiving cardiovascular/antidiabetic drug treatment or duration of disease >6 years did not alter the risk of reversing the metabolic syndrome. Our study showed that the natural course of metabolic syndrome is dynamic. A considerable number of patients developed or reversed the metabolic syndrome in one year follow-up.

Abstract
BACKGROUND Patients with severe mental illness (SMI) experience distress and disabilities in several aspects of life, and they have a higher risk of somatic co-morbidity. Both patients and their family members need the support of an easily accessible primary care system. The willingness of general practitioners and the impeding factors for them to participate in providing care for patients with severe mental illness in the acute and the chronic or residual phase were explored. METHODS A questionnaire survey of a sample of Dutch general practitioners spread over the Netherlands was carried out. This comprised 20 questions on the GP's 'Opinion and Task Perspective', 19 questions on 'Treatment and Experiences', and 27 questions on 'Characteristics of the General Practitioner and the Practice Organisation'. RESULTS 186 general practitioners distributed over urban areas (49%), urbanised rural areas (38%) and rural areas (15%) of the Netherlands participated. The findings were as follows: GPs currently considered themselves as the first contact in the acute psychotic phase. In the chronic or residual phase GPs saw their core task as to diagnose and treat somatic co-morbidity. A majority would be willing to monitor the general health of these patients as well. It appeared that GP trainers and GPs with a smaller practice setting made follow-up appointments and were willing to monitor the self-care of patients with SMI more often than GPs with larger practices.GPs also saw their role as giving support and information to the patient's family.However, they felt a need for recognition of their competencies when working with mental health care specialists. CONCLUSION GPs were willing to participate in providing care for patients with SMI. They considered themselves responsible for psychotic emergency cases, for monitoring physical health in the chronic phase, and for supporting the relatives of psychotic patients.

Abstract
OBJECTIVE To investigate the feasibility of switching overweight schizophrenic patients to aripiprazole and to assess the impact of 12 months of aripiprazole treatment on weight in routine practice. METHOD This was a non-controlled cohort study in overweight schizophrenic patients. Data were collected before treatment with aripiprazole was started and at 12-month follow-up. RESULTS A total of 53 patients were included; of these 55% continued using aripiprazole for 12 months. Aripiprazole treatment for 12 months (P = 0.027) and stopping clozapine or olanzapine treatment (P = 0.038) predicted weight loss (> or =3 kg). Patients receiving aripiprazole monotherapy (n = 16, mean -3.0 kg) had similar weight loss than patients receiving aripiprazole in addition to another antipsychotic drug (n = 13, mean -4.4 kg). CONCLUSION In routine practice once aripiprazole treatment was started, more than half of the patients remained on aripiprazole and most of them lost weight. Adding aripiprazole to clozapine gave similar weight loss as monotherapy with aripiprazole.

Abstract
BACKGROUND Antipsychotics are effective drugs that are prescribed frequently for a large group of patients. However, they also have many side-effects which can lead ultimately to serious somatic complications. These complications fall into various categories: metabolic, cardiovascular, neurobiological, haematological, gastro-intestinal and urogenital. AIM To make an inventory of the side-effects and advise on ways of monitoring and preventing them. method The multidisciplinary working group on somatic complications arising from the use of antipsychotics (Werkgroep Somatische Complicaties) has collected literature on the subject and has discussed it at a number of consensus meetings. results The most frequent somatic complications are described on the basis of specific risk profiles and advice is given on how to identify these complications and on how to treat them when necessary. It is essential to monitor, systematically and regularly, somatic complications arising from the use of antipsychotics; furthermore, polypharmacy should be avoided. The person ultimately responsible for this is the doctor who has prescribed the antipsychotics. In addition, it is important to draw patients' attention to the general rules for a healthy lifestyle: no smoking, a balanced diet and adequate exercise. CONCLUSION It is very important that somatic complications should be monitored carefully and accurately. So far, the Netherlands has no official guidelines on ways to identify and treat somatic complications.

Worsening of psychosis in schizophrenia is longitudinally associated with tardive dyskinesia in the European Schizophrenia Outpatient Health Outcomes study. Compr Psychiatry 2007; 48:436-40. [PMID: 17707251 DOI: 10.1016/j.comppsych.2007.05.003] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2007] [Revised: 04/27/2007] [Accepted: 05/02/2007] [Indexed: 01/23/2023] Open
Abstract
OBJECTIVE The objective of the study was to examine if worsening of psychosis predicts the emergence of tardive dyskinesia (TD). METHOD Global measures of TD and Clinical Global Impression (CGI) overall symptom severity score were rated in 4 assessments in 12 months. In a risk set free of TD at baseline, associations between TD onset and change in CGI scores were assessed using Cox proportional hazard regression. RESULTS A total of 8,620 patients yielded 23,565 follow-up observations, 8.8% of which represented a worsening in CGI overall symptom severity relative to the previous observation, yielding an incidence of TD of 5.2%, compared with 2.7% in observations without worsening of psychopathology (rate ratio, 1.9; 95% confidence interval, 1.3-2.7). Incidence of TD was longitudinally associated with a worsening of the CGI overall symptom severity in the months preceding TD onset (adjusted hazard ratio over 6 levels of CGI score, 1.3; 95% confidence interval, 1.1-1.4). CONCLUSION Worsening in overall psychopathology in schizophrenia is longitudinally associated with the emergence of TD as measured by CGI overall symptom severity.

How do General Practitioners experience providing care for their psychotic patients? BMC FAMILY PRACTICE 2007; 8:37.

Abstract
BACKGROUND In primary care, GPs usually provide care for patients with chronic diseases according to professional guidelines. However, such guidelines are not available in the Netherlands for patients with recurring psychoses. It seems that the specific difficulties that GPs experience in providing care for these patients hinder the development and implementation of such guidelines. This study aims to explore the chances and problems GPs meet when providing care for patients susceptible for recurring psychoses, including schizophrenia and related disorders, bipolar disorder, and psychotic depression. METHODS A qualitative study of focus group discussions with practising GPs in both town and rural areas. Transcripts from three focus groups with 19 GPs were analysed with the computer program 'Kwalitan'. Theoretical saturation was achieved after these three groups. RESULTS Analysis showed that eight categories of factors influenced the GPs' care for psychotic patients: patient presentation (acute vs. chronic phase), emotional impact, expertise, professional attitude, patient related factors, patient's family, practice organization, and collaboration with psychiatric specialists. CONCLUSION Current primary care for psychotic patients depends very much on personal characteristics of the GP and the quality of local collaboration with the Mental Health Service. A quantitative study among GPs using a questionnaire based on the eight categories mentioned above would determine the extent of the problems and limitations experienced with this type of care. From the results of this quantitative study, new realistic guidelines could be developed to improve the quality of care for psychotic patients.

Abstract
OBJECTIVE To compare the consequences of a guided discontinuation strategy and maintenance treatment in remitted first-episode psychosis in terms of relapse rates and functional outcome. METHOD The study was conducted in 7 mental health care organizations and the Department of Psychiatry of the University Medical Center Groningen in The Netherlands, covering a catchment area of 3.1 million inhabitants. A sample of 131 remitted first-episode patients, aged 18 to 45 years, with a DSM-IV diagnosis of schizophrenia or related psychotic disorder was included (i.e., all patients with a first psychotic episode from October 2001 through December 2002 who were willing to participate). After 6 months of positive symptom remission, they were randomly and openly assigned to the discontinuation strategy or maintenance treatment. Maintenance treatment was carried out according to American Psychiatric Association guidelines, preferably using low-dose atypical antipsychotics. The discontinuation strategy was carried out by gradual symptom-guided tapering of dosage and discontinuation if feasible. Follow-up was 18 months. Main outcome measures were relapse rates and social and vocational functioning. RESULTS Twice as many relapses occurred with the discontinuation strategy (43% vs. 21%, p = .011). Of patients who received the strategy, approximately 20% were successfully discontinued. Recurrent symptoms caused another approximately 30% to restart antipsychotic treatment, while in the remaining patients discontinuation was not feasible at all. There were no advantages of the discontinuation strategy regarding functional outcome. CONCLUSIONS Only a limited number of patients can be successfully discontinued. High relapse rates do not allow a discontinuation strategy to be universal practice. However, if relapse risk can be carefully managed by close monitoring, in some remitted first-episode patients a guided discontinuation strategy may offer a feasible alternative to maintenance treatment. Further research is needed to find predictors of successful discontinuation.

Evidence that early extrapyramidal symptoms predict later tardive dyskinesia: a prospective analysis of 10,000 patients in the European Schizophrenia Outpatient Health Outcomes (SOHO) study.

Abstract
OBJECTIVE This study examined whether extrapyramidal symptoms predict incidence of tardive dyskinesia 1 year later. METHOD Simple, global measures were used to rate extrapyramidal symptoms and tardive dyskinesia in a prospective, observational health outcomes study. Baseline and 3-, 6-, and 12-month data on 9,298 patients were analyzed by using a Cox proportional-hazard model. Onset of tardive dyskinesia was examined in two groups: 1) no tardive dyskinesia at baseline (broad risk set) and 2) no tardive dyskinesia at baseline and 3 months (narrow risk set). RESULTS Baseline extrapyramidal symptoms predicted later onset of tardive dyskinesia (broad risk set: hazard ratio=2.0, narrow risk set: hazard ratio=1.6). In analyses adjusted for age, gender, and medication exposure, this effect size was not reduced. About half of patients who developed tardive dyskinesia had earlier extrapyramidal symptoms. CONCLUSIONS Although the association of tardive dyskinesia and extrapyramidal symptoms is significant, extrapyramidal symptoms do not robustly identify individuals at high risk for tardive dyskinesia. However, drug regimens and disease processes that increase extrapyramidal symptoms are likely to result in increased risk of tardive dyskinesia.

Abstract
Tardive dyskinesia (TD) may occur in never-medicated patients with psychotic illness, indicating the existence of non-medication, possibly disease-related, causes. We tested the hypothesis that, independent of the antipsychotic-induced rise in prolactin, the incidence of TD would be associated with the incidence of prolactin-related sexual disturbances (PRSD), which would be suggestive of a common pathology involving multiple dopamine tracts. Simple, global measures of TD and PRSD (loss of libido, amenorrhea, gynaecomastia, impotence, and galactorrhea) were rated in a prospective, observational European Health Outcomes Study (SOHO). New onset of TD and new onset of PRSD at 3, 6, and 12 months was analyzed in a risk set of 4263 patients using a Cox proportional hazard model yielding adjusted hazard ratios (aHR). Incidence of TD was significantly and linearly comorbid with the incidence of PRSD in both men and women. Compared to those with no PRSD, the risk for TD was 2.0 (95% CI: 1.1, 3.7) with one PRSD, 2.4 (95% CI: 1.3, 4.5) with two PRSD, and 3.6 (95% CI: 1.1, 11.8) with three PRSD. Associations were stronger in those who only had received prolactin-sparing medications (aHR per unit PRSD increase=2.0, 95% CI: 1.2, 3.3) than in those who only had received prolactin-raising medications (aHR=1.3, 95% CI: 0.9, 1.9). In people with schizophrenia, TD and PRSD show comorbidities that are independent of antipsychotic-induced alterations in plasma prolactin. This may suggest a shared, pandopaminergic pathological mechanism associated with schizophrenia itself, rather than only a medication effect.

Abstract
OBJECTIVE To compare the incidence and persistence of tardive dyskinesia between patients diagnosed with schizophrenia (ICD-10 and/or DSM-IV) who were treated with second-generation antipsychotics and first-generation antipsychotics in routine clinical practice. METHOD The European Schizophrenia Outpatient Health Outcomes (SOHO) study is a 3-year, prospective, observational study. Each country had a start date for patient enrollment before October 2000. All enrollment was completed by June 30, 2001. A simple, global measure of tardive dyskinesia was rated by participating clinicians. For the current analysis, data at baseline, 3 months, and 6 months were analyzed using a generalized estimating equation model. RESULTS Second-generation antipsychotics conferred a lower risk for tardive dyskinesia at 6 months than first-generation antipsychotics (0.9% vs. 3.8%, odds ratio [OR] = 0.29, 95% confidence interval [CI] = 0.18 to 0.46). In addition, patients with tardive dyskinesia at baseline who were receiving second-generation antipsychotics were less likely than patients receiving first-generation antipsychotics to have tardive dyskinesia symptoms at 6 months (43.6% vs. 60.8%, OR = 0.50, 95% CI = 0.30 to 0.85). A sensitivity analysis suggested no bias related to pharmaceutical industry financial support. CONCLUSION The results suggest that the relative advantage of second-generation antipsychotics in terms of lower rates of incidence and persistence of tardive dyskinesia, observed in technical randomized controlled trials, generalizes to routine clinical care.

Abstract
BACKGROUND There is increasing evidence that cognitive-behavioural therapy can be an effective intervention for patients experiencing drug-refractory positive symptoms of schizophrenia. AIMS To investigate the effects of cognitive-behavioural therapy on in-patients with treatment-refractory psychotic symptoms. METHOD Manualised therapy was compared with supportive counselling in a randomised controlled study. Both interventions were delivered by experienced psychologists over 16 sessions of treatment. Therapy fidelity was assessed by two independent raters. Participants underwent masked assessment at baseline, after treatment and at 6 months' follow-up. Main outcome measures were the Positive and Negative Syndrome Scale and the Psychotic Symptoms Rating Scale. The analysis was by intention to treat. RESULTS Participants receiving cognitive cognitive-behavioural therapy had improved with regard to auditory hallucinations and illness insight at the post-treatment assessment, but these findings were not maintained at follow-up. CONCLUSIONS Cognitive-behavioural therapy showed modest short-term benefits over supportive counselling for treatment-refractory positive symptoms of schizophrenia.

Abstract
OBJECTIVE Novel antipsychotics are increasingly used in the treatment of bipolar and schizoaffective mania. This paper presents an overview of the controlled studies in this field. METHOD Using cross-references, a computerized search was performed on MEDLINE and EMBASE psychiatry covering the period 1990-2002. RESULTS Olanzapine and risperidone, added to mood stabilizers, and olanzapine as monotherapy enjoy the most evidential support in terms of efficacy and side-effect profile for their use in acute bipolar mania. The use of modern antipsychotics in bipolar prophylaxis and in both the short- and long-term treatment of schizomania has not been widely studied yet. CONCLUSION More controlled trials are still needed comparing modern antipsychotics as monotherapy and adjunctive to mood stabilizers with conventional antipsychotics, lithium, anticonvulsants and with each other in short-term and, especially, maintenance treatment of (schizo)mania. Partly based on controlled studies, olanzapine, risperidone and other modern antipsychotics could become preferable for these indications.

Abstract
Antipsychotic drugs are generally registered for treating schizophrenia, psychosis, mania, and conditions of severe (locomotor) agitation. In common practice, however, they are prescribed in a wide range of different psychiatric disorders. We conducted a retrospective, exploratory study to examine off-label use of antipsychotics and possibly sex differences. We defined antipsychotic use as quasi-label when used in non-registered disorders that have psychosis as an inherent co-morbidity. When antipsychotics were prescribed in disorders that are generally not known with psychosis, we defined this as off-label use. In this study, we combined pharmacy records with data from general practitioners in order to evaluate the range of diagnoses for which antipsychotic drugs are used. We focused on sex differences in type of disorder and in prescribed dosages of antipsychotic drugs. Among 97 male and 95 female antipsychotic users, we could classify women significantly more often as on-label antipsychotic drug users compared with men. Most often, this occurred with typical antipsychotic drug treatment. While female patients used equal dosages for on-label and quasi-/off-label indications, we found that male patients used significantly lower dosages in quasi-/off-label indications compared with on-label indications. We suggest elaborate future research on the characteristics of quasi- and off-label antipsychotic drug use in order to define effective and safe use of antipsychotic drugs among off-label indications.

Abstract
Cognitive dysfunction in schizophrenia has well-known functional consequences. The ability to learn (learning potential) may be an important mediator. This study examines the relationship between learning and functional status in schizophrenia patients before and after participation in a rehabilitation program. We reasoned that learning is a broad construct, encompassing controlled, effortful as well as automatic (learning by doing) mechanisms, called explicit and implicit learning, respectively. Both types of learning ability are important in daily life. The study included 44 medicated schizophrenia patients and 79 healthy controls. We included measures of implicit and explicit learning as well as measures of the cognitive domains for which significant relationships with functional outcome have been established: immediate and secondary verbal memory, card sorting and vigilance. Learning potential and the patient's 'learner status' were also assessed. The results show that learning, as assessed by measures of explicit and implicit learning and learning potential, was not associated with social functioning or rehabilitation outcome. The highest correlations between cognitive functioning and social functioning were found for more or less 'static' performance measures when they were assessed for a second time with or without instructions on how to do the test. Optimized cognitive performance (i.e. performance after instruction or training) seems to be a better predictor of complex domains of functioning than naive or everyday performance.

Abstract
OBJECTIVE To review evidence-based literature regarding the necessary duration of antipsychotic relapse prevention in schizophrenia and related psychoses. METHOD A computerized search was performed on Medline, Embase Psychiatry and PsycLIT which covered the period 1974-99. We also used cross-references. RESULTS Although schizophrenia refers mainly to an intrinsic biological vulnerability, only maintenance studies with a follow-up of 2 years at most are available. Relapses appear unpredictable and occur even after long-term successful remission during antipsychotic treatment. CONCLUSION Since rehabilitation efforts have effects only after long-term endeavours, antipsychotic relapse prevention should be maintained for long periods. It is reasonable to treat patients suffering from schizophrenia and related psychoses for longer periods than indicated by the current guidelines.

Abstract
Data are presented on the 15-year natural course of schizophrenia and other nonaffective functional psychoses in a cohort of 82 first-contact cases from a circumscribed area in the Netherlands. The subjects were suffering from functional psychosis with International Classification of Diseases-Ninth Revision (ICD-9) diagnoses 295, 297, or 298.3-9 (broad definition of schizophrenia) on entry. Standardized assessments of psychopathology, psychological impairments, negative symptomatology, social disability, and use of mental healthcare were used. The study reveals a pattern of chronicity and relapses with a high risk of suicide: Two-thirds of the subjects had at least one relapse and after each relapse 1 of 6 subjects did not remit from the episode; 1 of 10 committed suicide; and 1 of 7 had at least one episode with affective psychotic symptoms that started on average 6 years after the onset of the schizophrenic disorder. Diagnoses were reclassified in five patients, according to DSM-III-R criteria for a bipolar disorder. The predictive power--in terms of time in psychosis and in partial or full remission--of demographic, illness, and treatment variables at onset of the illness was very limited. Insidious onset and delays in mental health treatment are risk factors that predict a longer duration of first or subsequent episodes. The importance of mental health treatment in regard to outcome is probably subject to change because an early warning and intervention strategy could prevent further damage and deterioration. Our data support the need for an adequate relapse prevention program as a priority for our mental health services.

Abstract
Need for care was studied in a Dutch incidence cohort of patients with schizophrenic disorders 15 and 17 years from first onset of psychosis. Long-term course of the disorders varied from complete remission and full community participation to chronic psychosis and long-term hospital stay. Fifty patients were assessed twice with the Needs For Care Assessment Schedule (NFCAS, Brewin and Wing 1989); at the latter follow-up an assessment was also made using the Camberwell Assessment of Need (CAN, Phelan et al. 1995). The NFCAS is an investigator- or professional-based instrument which provides an 'objective' assessment of needs. Need for care was recorded in 22 areas of clinical and social functioning. Comparison of the two assessments over a 2-year period demonstrated a high stability on the individual items (mean 88%, mostly concerning the absence of a problem twice), but did not show the expected stability of need status among this group of patients with chronic disorders. One in five patients (22%) had no needs at all on both occasions and 56% of the patients showed a change in needs. There was more negative than positive change: 28% suffered from new unmet needs at the 17-year follow-up, while only 12% had improved their status to no needs. About one-third (36%) had at least one unmet need, mostly regarding psychotic symptoms, dyskinesia or underactivity. The CAN provides a 'subjective' assessment of needs according to the view of patients themselves. The problems patients reported most commonly were in the areas of day-time activities, social relationships and information on their condition and treatment, for all which they asked for more help than they received. This patient-based instrument produces slightly higher numbers of problems and unmet needs, and a lower ratio between met and unmet needs. There is an overall percentage of 21% of disagreement between patient and investigator view regarding the unmet need status. Agreement between the two instruments on the nature of the problems with unmet needs was lacking altogether.

Abstract
Severe and long term mental disorders, like schizophrenia, show in general a wide range of psychiatric signs and symptoms, psychological and physiological impairments and social disablement (Shepherd, 1994; Wing, 1982) reflecting a variety of mental health needs. Many studies provide only a cross-sectional view of the clinical and social problems of the patient population, for example at intake or admission to a mental hospital. Longitudinal studies following patients after discharge for some period of months or years show in general the expected improvement of functioning (e.g. Nienhuis et al., 1994), but as far as only chronic patients are concerned such a positive change is much less noted. The concept of chronicity of mental disorders would presume that after some time needs are fairly predictable and stable and do not change much over time. Our investigation on the long-term course of schizophrenia (Wiersma et al., 1996; 1997) enables us to study over a period of two years, from 15 to 17 years since first onset of psychosis, the stability or variability of needs in schizophrenic disorder. We are not aware of empirical studies on changes in needs among patients with long-term disorders.

Abstract
We examined the influence of an educational programme on nurses' level of expressed emotion (EE), on ward climate and on social functioning and psychopathology of hospitalized schizophrenic patients. Nurses and patients were from long-stay wards of six Dutch psychiatric hospitals. Despite an increase of nurses' knowledge about schizophrenia we did not find measurable effects on nurses' levels of EE. According to the five minute speech sample method, a third of the nurses participating in this study had a high level of expressed emotion, mainly consisting of criticism. This was a rather stable pattern. Patients, however, were reluctant to give their nurses high EE ratings on the level of expressed emotion scale. Psychopathology was not influenced by the educational programme, but social functioning of patients was related to EE in nurses. Moreover, we found a significant decline in the number of restrictive ward rules at follow-up. We conclude that, while it may be difficult to detect changes in EE level after an educational programme for nurses, there nevertheless appear to be measurable benefits for patients.

Abstract
Assessment of needs for care is crucial in the evaluation of ongoing changes from institutional care to various forms of day- and outpatient treatment. Do patients really do better in the community and are they adequately cared for? The 15-year follow-up of a Dutch incidence cohort of patients with schizophrenia and other functional non-affective psychoses showed that 47 (out of 63) patients had positive ratings of symptoms and disabilities. They were assessed by means of the Needs for Care Assessment Schedule, which articulates the problems and corresponding interventions resulting in a judgement of met or unmet need for treatment or assessment. There was a mean of 2.1 clinical problems and 2.1 social problems per patient. Few problems were considered to generate unmet needs: 14% of the clinical problems and only 7% of the social problems. Nevertheless, 32% of the patients had one or more unmet needs. These results were compared with data from six research centres in the United Kingdom (Camberwell, Oxford and South Glamorgan), Canada (Montreal), Italy (Verona) and Finland (Tampere). Despite differences in health care settings in the four countries, the ratio of met to unmet needs (about 4-5 to 1) among chronic, mostly schizophrenic patients is more or less the same with the exception of an apparently underserved hostel population in Oxford and the Finnish patient population probably due to high expectations with respect to independent community living.

Abstract
Generalization of skills is a major problem in social skills training for schizophrenic patients. Assessment of skills is mostly not based on objective indices of specific skill deficits. The results of this study show that global competence of schizophrenics can be differentiated from specific competence. Global competence was found to be related to symptoms, whereas specific competence was not. No support was found for the assumption that social dysfunctions are caused by negative symptoms. Social perception and positive symptoms did explain a substantial part of the variance of global competence. It is therefore concluded that neither global incompetence nor negative symptoms should be used as an indication for social skills training.

Abstract
We investigated whether the lack of therapeutic response to long-term and adequate neuroleptic treatment was due to a failure to achieve a blockade of cerebral dopamine receptors. Six chronic schizophrenic and medicated patients (DSM-III-R diagnosis, paranoid or disorganized type) were assessed with the Present State Examination and the Brief Psychiatric Rating Scale. According to the Chouinard Rating Scale there were little extrapyramidal symptoms, although no anticholinergic drugs were given. Plasma levels of the neuroleptics were determined and found in the therapeutic range or higher. Dopamine D2-receptor occupancy was determined with positron emission tomography using 11C-methylspiperone as ligand. There was a more than 95% blockade of the D2 receptors in the striatum. These results indicate that the lack of therapeutic response and extra-pyramidal side effects cannot be attributed to an incomplete blockade of cerebral D2 receptors and that the pathogenetic role of these receptors can be questioned in therapy-resistant schizophrenic patients.

Abstract
Two diagnostic systems are compared in a psychiatric outpatient population of 175 patients. The Present State Examination (PSE)-Catego system identified 121 patients (69%) as "cases," whereas DSM-III identified 152 patients (87%) as cases. The two systems converged in 115 patients, yielding a kappa coefficient of only .32. Approximately one third of the DSM-III cases that were not detected by the PSE-Catego system was due to the restricted coverage of the latter system; the remaining two thirds could be attributed to differences in threshold and time framing. Compared with DSM-III, the PSE-Catego system showed a strong bias toward depression, and the system was extremely insensitive to the detection of social phobias and obsessive-compulsive disorders. Only 58% of cases of depression and 46% of cases of anxiety were diagnosed by both systems. The results are compared with other studies, and some consequences are discussed.

Abstract
The effectiveness of lithium prophylaxis in bipolar affective disorders is generally supported in the literature. The effects in this group, as well as in unipolar depressions and schizo-affective disorders were studied, using an individual retrospective control method, and the Life Table method. Lithium prophylaxis resulted in a substantial decrease in the number of episodes and hospital admissions in bipolar and schizo-affective disorders. In addition, these two groups showed frequent relapses after termination of the prophylaxis. The number of episodes preceding the prophylaxis and the absence of unipolar depression are found to be predictors of effectiveness. The consequences of patient selection and of inconclusive diagnostic criteria are pointed out.

Abstract
To gain more insight into the social (as opposed to clinical) outcome of schizophrenia, a unidimensional, heirarchical scale was constructed. Items were selected from the Disability Assessment Schedule (DAS)--a new instrument, used in the WHO Collaborative Study on the Assessment and Reduction of Psychiatric Disability. Data were derived from the Dutch cohort participating in this study, which consisted of patients with a first life-time episode of a non-affective, functional psychosis. Patients were followed-up during the first three years of their illness, and analyses of the stability and reliability of the scale proved to be satisfactory. It was subsequently used to characterise the course of social disability.

Abstract
In order to evaluate Foulds' hierarchical model of psychiatric illness, a study was carried out using data from a 3-year follow-up of patients suffering from functional non-affective psychoses. Of the 177 Present State Examinations carried out 86% yielded symptom patterns compatible with the model. It was shown that failures to fit the hierarchy can be explained either by measurement error or by the masking of major symptoms by the simultaneous presence of minor ones. A one-dimensional scale to measure the severity of psychiatric illness was constructed. Patients' scores were compared with ratings on the Index of Definition and the diagnosis of current mental state. The results of these comparisons were considered to be supportive validatory evidence. Some of the implications of the model and the data are discussed.

Abstract
Recent data from a 2-year follow-up of functional non-affective psychosis, and particularly schizophrenia, favoured social selection rather than social causation theory. Data concerning the cohort were compared with inter- and intra-generational mobility in a random Dutch sample. The results indicate that the educational and occupational mobility of patients, relative to their fathers, was greater than expected. Although patients were better educated than the random sample, they fared less well occupationally. An analysis of patterns of occupational mobility before and after the onset of psychosis also showed that social selection played a major role in achieving social status. The outcome of patients' occupational career at follow-up was poor, and only a minority succeeded in obtaining or keeping a regular job.
