Relationship between prolactin, breast cancer risk, and antipsychotics in patients with schizophrenia: a critical review.

OBJECTIVE: A recent meta-analysis showed that breast cancer probably is more common in female patients with schizophrenia than in the general population (effect size = 1.25, P < 0.05). Increasing experimental and epidemiological data have alerted researchers to the influence of prolactin (PRL) in mammary carcinogenesis. We therefore investigated the possible relationship between antipsychotic-induced hyperprolactinemia (HPRL) and breast cancer risk in female patients with schizophrenia. METHOD: A literature search (1950 until January 2015), using the MEDLINE database, was conducted for English-language published clinical trials to identify and synthesize data of the current state of knowledge concerning breast cancer risk (factors) in women with schizophrenia and its (their) relationship between HPRL and antipsychotic medication. RESULTS: Although an increasing body of evidence supports the involvement of PRL in breast carcinogenesis, results of human prospective studies are limited, equivocal, and correlative (with risk ratios ranging from 0.70 to 1.9 for premenopausal women and from 0.76 to 2.03 for postmenopausal women). Moreover, these studies equally do not take into account the local production of PRL in breast epithelium, although amplification or overexpression of the local autocrine/paracrine PRL loop may be a more important mechanism in tumorigenesis. Until now, there is also no conclusive evidence that antipsychotic medication can increase the risk of breast malignancy and mortality. CONCLUSION: Other breast risk factors than PRL, such as nulliparity, obesity, diabetes mellitus, and unhealthy lifestyle behaviours (alcohol dependence, smoking, low physical activity), probably are of greater relevance in individual breast cancer cases within the population of female patients with schizophrenia.

The effects of novel and newly approved antipsychotics on serum prolactin levels: a comprehensive review.

Since the 1970s, clinicians have increasingly become more familiar with hyperprolactinemia (HPRL) as a common adverse effect of antipsychotic medication, which remains the cornerstone of pharmacological treatment for patients with schizophrenia. Although treatment with second-generation antipsychotics (SGAs) as a group is, compared with use of the first-generation antipsychotics, associated with lower prolactin (PRL) plasma levels, the detailed effects on plasma PRL levels for each of these compounds in reports often remain incomplete or inaccurate. Moreover, at this moment, no review has been published about the effect of the newly approved antipsychotics asenapine, iloperidone and lurasidone on PRL levels. The objective of this review is to describe PRL physiology; PRL measurement; diagnosis, causes, consequences and mechanisms of HPRL; incidence figures of (new-onset) HPRL with SGAs and newly approved antipsychotics in adolescent and adult patients; and revisit lingering questions regarding this hormone. A literature search, using the MEDLINE database (1966-December 2013), was conducted to identify relevant publications to report on the state of the art of HPRL and to summarize the available evidence with respect to the propensity of the SGAs and the newly approved antipsychotics to elevate PRL levels. Our review shows that although HPRL usually is defined as a sustained level of PRL above the laboratory upper limit of normal, limit values show some degree of variability in clinical reports, making the interpretation and comparison of data across studies difficult. Moreover, many reports do not provide much or any data detailing the measurement of PRL. Although the highest rates of HPRL are consistently reported in association with amisulpride, risperidone and paliperidone, while aripiprazole and quetiapine have the most favorable profile with respect to this outcome, all SGAs can induce PRL elevations, especially at the beginning of treatment, and have the potential to cause new-onset HPRL. Considering the PRL-elevating propensity of the newly approved antipsychotics, evidence seems to indicate these agents have a PRL profile comparable to that of clozapine (asenapine and iloperidone), ziprasidone and olanzapine (lurasidone). PRL elevations with antipsychotic medication generally are dose dependant. However, antipsychotics having a high potential for PRL elevation (amisulpride, risperidone and paliperidone) can have a profound impact on PRL levels even at relatively low doses, while PRL levels with antipsychotics having a minimal effect on PRL, in most cases, can remain unchanged (quetiapine) or reduce (aripiprazole) over all dosages. Although tolerance and decreases in PRL values after long-term administration of PRL-elevating antipsychotics can occur, the elevations, in most cases, remain above the upper limit of normal. PRL profiles of antipsychotics in children and adolescents seem to be the same as in adults. The hyperprolactinemic effects of antipsychotic medication are mostly correlated with their affinity for dopamine D2 receptors at the level of the anterior pituitary lactotrophs (and probably other neurotransmitter mechanisms) and their blood-brain barrier penetrating capability. Even though antipsychotics are the most common cause of pharmacologically induced HPRL, recent research has shown that HPRL can be pre-existing in a substantial portion of antipsychotic-naïve patients with first-episode psychosis or at-risk mental state.

Comorbid substance abuse in first-episode schizophrenia: effects on cognition and psychopathology in the EUFEST study.

UNLABELLED: Studies and meta-analyses investigating the influence of substance use disorder (SUD) (substance abuse or dependence) on psychopathology and neurocognitive function in schizophrenia patients have revealed controversial results. Most studies did only have small samples and did not focus exclusively on first-episode schizophrenia patients. METHOD: In a post-hoc analysis of the European First Episode Schizophrenia Trial (EUFEST) psychopathology and cognitive performances of patients with (FE-SUD, N=119, consisting of N=88 patients with persisting SUD at baseline and N=31 patients with previous SUD) and without SUD (FE-non-SUD, N=204) were compared at baseline and 6 months follow-up. Neurocognitive assessment included the Rey Auditory Verbal Learning Test (RAVLT); Trail Making Tests A and B (TMT), Purdue Pegboard and Digit-Symbol Coding. RESULTS: In total 31.1% of patients reported SUD, and 22.2% of patients used cannabis. There were no significant differences between patients with and without SUD concerning PANSS scores, extrapyramidal motor symptoms or neurocognitive measures except better performance in psychomotor speed (TMT-A, p=0.033, Cohen's d=0.26) in patients with SUD at 6 months follow-up. Interestingly, SUD patients with ongoing substance use at follow-up showed elevated positive symptoms (PANSS positive score, p=0.008, Cohen's d=0.84) compared to those who abstained. PANSS scores at baseline were increased in patients with an onset of SUD before the age of 16 years. In addition we found a correlation between longer duration of cannabis use and higher cognitive performance as well as reduced symptom improvement and more extrapyramidal motor symptoms in patients with higher frequency of cannabis consumption. CONCLUSIONS: FE-SUD and FE-non-SUD show similar psychopathology and neuropsychological performances at baseline and during the first 6 months of antipsychotic treatment.

Familial sinistrality and handedness in patients with first episode schizophrenia: the EUFEST study.

The population with schizophrenia is characterised by a leftward shift in handedness-sinistrality. However, findings are inconsistent in chronic patients, and familial sinistrality (FS), defined as the presence of left-handed close relatives, might contribute to the discrepancies. Therefore the aim of this study was to investigate the strength of manual lateralisation in patients with first episode schizophrenia, taking into account familial sinistrality. The Edinburgh Inventory (EI) allowed us to categorise 179 patients from the EUFEST study and 189 controls presenting "strong handedness" (SH: EI absolute value between ∣81∣ and ∣100∣) or "weak-handedness" (WH: EI value between -80 and +80). The nominal logistic regression did not show an FS effect, but a nearly significant interaction between illness and FS (p =.07). There were fewer participants without FS presenting SH among patients (99/151: 65.6%) than among controls (134/164: 81.7%, p =.001). In contrast, the number of participants with FS presenting SH was similar between controls (68%) and patients (75%, p =.57). The presence of left-handed relatives (FS + ) tended to reduce manual lateralisation, but only in controls. This supports the notion that reduced manual lateralisation in schizophrenia is related to the illness rather than to familial left-handedness.

Setting new standards in schizophrenia outcomes: symptomatic remission 3 years before versus after the Andreasen criteria.

Symptomatic remission is often mentioned as one of the treatment goals for schizophrenia. However, the consistently with which this is documented in the schizophrenia literature since the introduction of the consensus criteria proposed by Andreasen and colleagues in 2005 has yet to be investigated. Similarly, additional treatment goals which are being discussed include improved functioning and quality of life, but whether these goals are being increasingly documented in the literature alongside symptomatic remission is as yet unknown. The objective of this article is therefore to review the use of the term 'remission' in the schizophrenia literature from Europe, U.S.A. and the rest of the world from 2002 to 2007, before and after the introduction of the Andreasen criteria. A second objective is to determine whether these manuscripts documenting symptomatic remission are also addressing other concepts such as functioning, quality of life and relationships. This literature review indicates that the use of the Andreasen criteria is indeed increasing, although there are manuscripts documenting alternative remission criteria or using the term remission without documentation of specific remission criteria. From 2004 to 2007 the number of manuscripts mentioning remission without documenting specific criteria has fallen by approximately 50%. Within these manuscripts there is increasing awareness of functioning and quality of life as outcome measures, in particular in manuscripts generated in Europe and the U.S.A. This review highlights the growing importance of co-assessment of symptomatic remission and functional outcomes, and calls for further consideration of the most appropriate and consistent way to evaluate functioning of schizophrenia patients.

No gender differences in social outcome in patients suffering from schizophrenia.

Differences between female and male patients with schizophrenia in psychopathology and course of illness have frequently been reported. However, the influence of sex on symptomatic and social remission is still an open issue. In the present study, differences between males and females in both clinical and social remission rates and in scores on several scales assessing social functioning were evaluated in 295 stabilized patients with schizophrenia, schizoaffective or delusional disorder. Female patients, as compared with males, showed a later onset of the illness, less negative symptoms and less frequent alcohol abuse. No significant difference was found between females and males in the rate of symptomatic and functional remission. No significant effect of sex was observed on any index of social functioning.

A prospective, multicentre, open-label study to evaluate the effectiveness of aripiprazole in the treatment of a broad range of patients with schizophrenia.

PURPOSE: The aim of this study is to evaluate the effectiveness of 12-week treatment with aripiprazole in a broad range of patients suffering from schizophrenia by using a variety of physicians, caregivers and patients scales. SUBJECTS AND METHODS: A total of 361 in- or outpatients who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for schizophrenia received open-label aripiprazole (10-30 mg per day) in this 12-week, prospective, multicentre, uncontrolled study. The primary endpoint was the Clinical Global Impression-Improvement (CGI-I) scale which measured effectiveness of study medication, including efficacy, safety and tolerability. A variety of physician-, patient- and caregiver-rated parameters were measured to gain a complete view of the effectiveness of aripiprazole. RESULTS: The effectiveness of aripiprazole treatment was demonstrated in a broad range of schizophrenia patients (CGI-I score of 3.0; 95% confidence interval: 2.8, 3.2: last observation carried forward [LOCF]) as the upper bound of the 95% CI was less than 4 (score of "no change"). Both patient and caregiver PGI-I scores (LOCF: 95% CI: 2.79, 3.09 and, 95% CI: 2.74, 3.17, respectively) corroborate this finding. Aripiprazole had a positive effect on disease severity by study end, as assessed by an increase of the (physician-rated) CGI-S scores, with 57.3% of patients having improved disease, one-third maintaining their condition (30.8%) and 11.3% with worsening symptoms (LOCF). The Investigator Assessment Questionnaire (IAQ) showed a great improvement (>50% of patients). Patients reported significantly improved quality of life and overall, 71% of patients and 67% of caregivers preferred aripiprazole to their previous antipsychotic medication (LOCF; P<0.0001 over time). CONCLUSION: Aripiprazole was effective in a broad range of patients with schizophrenia.

How are we assessing functioning in schizophrenia? A need for a consensus approach.

Efforts to improve everyday living skills are important in schizophrenia. What constitutes appropriate functioning is however difficult to evaluate. Several instruments were tested in different settings throughout Europe (EGOFORS initiative), including two new questionnaires (FROGS, PSRS), to provide directions on domains to be assessed and tools to be used.

[Body-directed techniques on psychomotor therapy for people with schizophrenia: a review of the literature]. / Lichaamsgerichte werkvormen binnen de psychomotorische therapie voor mensen met schizofrenie: een literatuuronderzoek.

BACKGROUND: Patients with schizophrenia frequently undergo a disturbance of body experience. This can occur during an acute psychotic phase or during a period of remission. AIM: To investigate the scientific evidence of the effects of introducing body-directed techniques into psychomotor therapy for patients with schizophrenia. METHOD: PubMed, PEDro, CINAHL, psycINFO and SPORTDiscus were searched form 1 January, 2000, tot 1 January 2011, for reports of randomised controlled trials, controlled clinical trials and for studies wit a different design. The Tijdschrift voor Psychiatrie (the Dutch Journal of Psychiatry), the Tijdschrift voor Vaktherapie (The Journal for Special therapies) and Actuele Themata (Actual Themes) in psychomotor therapy were also screened. The quality of the methodology was assessed with the help of a checklist. Evidence for the efficacy of the interventions was summarised on the basis of a best-evidence synthesis. RESULT: Eleven studies satisfied our inclusion and exclusion criteria. There was a strong evidence for the reduction of psychiatric symptoms after yoga and reduced feelings of anxiety and stress after progressive muscle relaxation. There is limited evidence for yoga in reducing feelings of anxiety and stress and for body-directed group techniques in reducing negative symptoms. Qualitative research reported that mindfulness ­ and massage-techniques were able to considerably reduce feelings of stress. There is no evidence for the beneficial effects of dancing techniques. CONCLUSION: A body-directed approach can be effective an deserves to be included in the multidisciplinary treatment of schizophrenia.

Guidelines for screening and monitoring of cardiometabolic risk in schizophrenia: systematic evaluation.

BACKGROUND: Metabolic and cardiovascular health problems have become a major focus for clinical care and research in schizophrenia. AIMS: To evaluate the content and quality of screening guidelines for cardiovascular risk in schizophrenia. METHOD: Systematic review and quality assessment of guidelines/recommendations for cardiovascular risk in people with schizophrenia published between 2000 and 2010, using the Appraisal of Guidelines for Research and Evaluation (AGREE). RESULTS: The AGREE domain scores varied between the 18 identified guidelines. Most guidelines scored best on the domains 'scope and purpose' and 'clarity of presentation'. The domain 'rigour of development' was problematic in most guidelines, and the domains 'stakeholder involvement' and 'editorial independence' scored the lowest. The following measurements were recommended (in order of frequency): fasting glucose, body mass index, fasting triglycerides, fasting cholesterol, waist, high-density lipoprotein/low-density lipoprotein, blood pressure and symptoms of diabetes. In terms of interventions, most guidelines recommended advice on physical activity, diet, psychoeducation of the patient, treatment of lipid abnormalities, treatment of diabetes, referral for advice and treatment, psychoeducation of the family and smoking cessation advice. Compared across all domains and content, four European guidelines could be recommended. CONCLUSIONS: Four of the evaluated guidelines are of good quality and should guide clinicians' screening and monitoring practices. Future guideline development could be improved by increasing its rigour and assuring user and patient involvement.

[Aripiprazole-induced parkinsonism in a 64-year-old female patient diagnosed with bipolar disorder]. / Door aripiprazol geïnduceerd parkinsonisme bij een 64-jarige patiënte met een bipolaire stoornis.

A 64-year-old female patient, diagnosed with bipolar disorder, developed parkinsonism 18 days after aripiprazole had been initiated. Twenty-six days after the patient had stopped taking aripiprazole the parkinson syndrome disappeared completely. Aripiprazole is usually associated with a low incidence of extrapyramidal symptoms. So far, little is known about the pathophysiology of parkinsonism and the possible role of aripiprazole. The case-study includes some hypotheses and recommendations.

[Validity of nonaffective functional psychosis of the DSM IV in a Congolese population. A transversal clinical trial]. / Validité des psychoses fonctionnelles non affectives du DSM IV dans une population congolaise. Une étude clinique transversale.

BACKGROUND: The fourth edition of Diagnostic and Statistical Manual of Mental Disorders (DSM IV) distinguishes schizophrenia, schizophreniform disorder and brief psychotic disorder only according to the duration of the illness. Thus, the validity of these nosological concepts sounds uncertain. AIM: The aim of this study was to evaluate the validity of the DSM IV concepts schizophrenia, schizophreniform disorder and brief psychotic disorder. POPULATION AND METHODS: Seventy schizophrenics, 68 patients with brief psychotic disorder and 50 with schizophreniform disorder, all Congolese people, selected from the 'Telema' Mental Health Centre and the 'Neuropsychopathological centre of the University of Kinshasa, from 5(th) August 2003 to 14(th) March 2005 were compared with respect to the following clinical parameters: family schizophrenia and brief psychoses history, precipitating psychosocial factors, mode of onset of the disease, clinical syndromes linked to psychoses and general functioning. Statistical analyses included analysis of variances 'one way' (Anova), post hoc Tukey's test, discriminant analysis, and analysis of covariances. RESULTS: Brief psychotic disorder differed from schizophrenia and schizophreniform Disorder in respect with positive syndrome (F=8.76, df=2; 179, p=0.0002), cognitive syndrome (F=3.79, df=2; 179, P=0.024), syndrome of excitement (F=3.23, df=2; 179, P=0.042), general functioning (F=13.73, df=2; 179, P<0.0001), family history of schizophrenia (χ(2)=8.65; P=0.013), precipitating psychosocial factors (χ(2)=19.82; P<0.0001), and mode of onset of the disease (χ(2)=91.3; P<0.0001). Schizophreniform disorder differered from schizophrenia only by a more frequent acute onset and a better general functioning. Two nosological realities were thus distinguishable: brief psychotic disorder and schizophrenia-schizophreniform disorder complex. Surprisingly, negative syndrome could not distinguish brief psychotic disorder from schizophrenia and schizophreniform (F=2.80, df=2; 179, P=0.063). Data of the discriminant analysis based on scores on general functioning, positive, negative, depressive, cognitive and excitement syndromes was conclusive (F=6.41, df=2; 185, P<0.0001) and allowed correct classification rates of 75% for brief psychotic disorder, 48% for schizophreniform disorder, 54% for schizophrenia. Schizophreniform disorder was thus the less distinguishable group; this is in the line with longitudinal studies, which demonstrated the lowest diagnostic stability of this affection, compared with the two other diseases. Total error rate was 41%. CONCLUSIONS: Brief psychotic disorder could constitute a distinct affection from schizophrenia and schizophreniform disorder, whereas schizophreniform disorder and schizophrenia could be the same affection; the first being an acute and "good functioning" form of the second. However, these viewpoints need to be confirmed by data on long-term course. The data of this study validate ultimately a binary model of the major nonaffective functional psychoses, like that of the tenth edition of the International classification of mental and behavioural disorders (ICD-10).

[Clinical assessment of the ultra high risk of developing a a psychotic disorder; review and critical reflection]. / Klinische beoordeling van sterk verhoogd risico op psychose: overzicht en kritische reflectie.

BACKGROUND: It may be possible to improve the prognosis of psychotic disorders by the timely recognition and treatment of the early stages of these disorders. Since the first psychotic episode is often preceded by a period of non-specific symptoms and functional decline, it could be worthwhile investigating whether this early phase can be detected. AIM: To review existing diagnostic approaches and clinical instruments that are currently used for prospective identification of the prodromal phase. METHOD: We searched the literature between 1995 and 2009 using the search terms 'prodromal' or 'ultra high risk' in combination with 'psychosis' or 'schizophrenia' and 'assessment'. RESULTS: In international literature we found four diagnostic approaches to ultra high risk of psychosis: the attenuated positive symptom approach, the basic symptom approach, the clinical high risk approach and the strictly phenomenological approach. Within each of these approaches specific screening instruments had been developed and tested with regard to their ability to correctly predict a first psychotic episode. CONCLUSION: None of the current diagnostic approaches produces a sufficiently reliable prediction of the risk of a first psychotic episode. Within the group of persons assumed, based on screening, to be at very high risk, only a small percentage will actually develop a psychotic disorder.

Ziprasidone vs olanzapine in recent-onset schizophrenia and schizoaffective disorder: results of an 8-week double-blind randomized controlled trial.

INTRODUCTION: Head-to-head comparisons of antipsychotics have predominantly included patients with chronic conditions. The aim of the present study was to compare the efficacy and tolerability of ziprasidone and olanzapine in patients with recent-onset schizophrenia. METHODS: The study was an 8-week, double-blind, parallel-group, randomized, controlled multicenter trial (NCT00145444). Seventy-six patients with schizophreniform disorder, schizophrenia or schizoaffective disorder (diagnosis < 5 y), and a maximum lifetime antipsychotic treatment < 16 weeks participated in the study. Efficacy of ziprasidone (80-160 mg/d) and olanzapine 10-20 mg was measured using the Positive and Negative Syndrome Scale (PANSS), the Clinical Global Impression (CGI) Scale, the Calgary Depression Scale for Schizophrenia (CDSS), and the Heinrich Quality of Life Scale (HQLS); tolerability assessments included laboratory assessments, body weight, and electroencephalogram. RESULTS: Olanzapine (n = 34) and ziprasidone (n = 39) showed equal efficacy as measured by the PANSS, CDSS, CGI, and HQLS. However, mean weight gain was significantly higher in the olanzapine group (6.8 vs 0.1 kg, P < .001). Ziprasidone was associated with decreasing levels of triglycerides, cholesterol, and transaminases, while these parameters increased in the olanzapine group (all P values < .05). There were no significant differences in fasting glucose and prolactin levels or in cardiac or sexual side effects. Patients on ziprasidone used biperiden for extrapyramidal side effects more frequently (P < .05). DISCUSSION: The results of this study indicate that ziprasidone and olanzapine have comparable therapeutic efficacy but differ in their side effect profile. However, there is a risk of a type II error with this sample size. Clinically significant weight gain and laboratory abnormalities appear early after initiating treatment and are more prominent with olanzapine, while more patients on ziprasidone received anticholinergic drugs to treat extrapyramidal symptoms.

Second-generation antipsychotics and constipation: a review of the literature.

Antipsychotics are the cornerstone in the management of psychotic disorders and schizophrenia. They are effective agents but also have a wide range of side effects. In the recent literature constipation as possible side effect has received little attention. A review of the literature concerning constipation associated with antipsychotics was performed. Overall constipation is a rarely studied or reported side effect of antipsychotic medication. Nevertheless constipation is a common side effect. Antipsychotic agents differ in their liability to induce constipation. Constipation can be severe and can lead to serious consequences such as paralytic ileus, bowel occlusion and death. Active screening, monitoring and treatment are recommended. Further research on incidence, prevalence, underlying mechanisms and preventive measures is required.

Suicide attempts in a prospective cohort of patients with schizophrenia treated with sertindole or risperidone.

The incidence of suicide attempts (fatal and non-fatal) was analysed in a prospective cohort of patients with schizophrenia randomly assigned to sertindole (4905 patients) or risperidone (4904 patients) in a parallel-group open-label study with blinded classification of outcomes (the sertindole cohort prospective study--SCoP). The total exposure was 6978 and 7975 patient-years in the sertindole and risperidone groups, respectively. Suicide mortality in the study was low (0.21 and 0.28 per 100 patients per year with sertindole and risperidone, respectively). The majority (84%) of suicide attempts occurred within the first year of treatment. Cox's proportional hazards model analysis of the time to the first suicide attempt, reported by treating psychiatrists and blindly reviewed by an independent expert group according to the Columbia Classification Algorithm of Suicide Assessment (both defining suicide attempts by association of suicidal act and intent to die), showed a lower risk of suicide attempt for sertindole-treated patients than for risperidone-treated patients. The effect was statistically significant with both evaluation methods during the first year of randomized treatment (hazard ratios [95% CI]: 0.5 [0.31-0.82], p=0.006; and 0.57 [0.35-0.92], p=0.02, respectively). With classification by an independent safety committee using a broader definition including all incidences of intentional self-harm, also those without clear suicidal intent, the results were not significant. A history of previous suicide attempts was significantly associated with attempted suicides in both treatment groups.

Effects on cognitive functioning after olanzapine-ziprasidone crossover in recent-onset schizophrenia.

INTRODUCTION: To enhance functional outcome in schizophrenia improvement of cognitive symptoms is crucial. EXPERIMENTAL PROCEDURES: Using a comprehensive test battery, this follow-up examines cognitive effects in patients with recent-onset schizophrenia after a change of medication following insufficient clinical response and intolerance. RESULTS: After eight weeks cognitive outcomes had not improved in the patients having switched from olanzapine to ziprasidone (n=11; mean dose 136 mg) nor in those having switched from ziprasidone to olanzapine (n=10; mean 16 mg), while the symptoms of patients maintaining olanzapine (n=18; mean 10.9 mg) or ziprasidone (n=18; mean 88.9 mg) treatment had not improved further. DISCUSSION: The findings suggest that also in early-stage schizophrenia the antipsychotics tested affect cognitive symptoms similarly.

[The therapeutic value of physical exercise for people with schizophrenia]. / De therapeutische waarde van bewegen voor mensen met schizofrenie.

BACKGROUND: Only about 25% of people with schizophrenia follow the public health recommendations for a minimum of 150 minutes per week of moderate physical exercise. In their leisure time people diagnosed with schizophrenia take considerably less exercise than their healthy counterparts. AIM: To collect scientific evidence of movement-related interventions in patients with schizophrenia. METHOD: PubMed, PEDro, CINAHL, PsychINFO and Sport Discus were searched for the period from 2003 up to April 2009 for reports of randomised controlled trials (RCTs) on the basis of the search terms 'schizophrenia', 'exercise' and 'physical activity'. Relevant literature was also traced by means of the reference lists for selected articles. RESULTS: Eight RCTs were selected. Physical exercise was reported to bring about significant improvements in cardiovascular and metabolic parameters and in psychiatric symptomatology. A physical exercise also has social advantages; it helps patients to cope with stress and improves their quality of life. CONCLUSION: Physical exercise as part of psychomotor therapy should play an important role within the multidisciplinary treatment of schizophrenia. More research is needed into the effect of physical activity on cognitive functioning.

Physical health management in psychiatric settings.

Severe mental disorders have a chronic course associated with a high risk for co-morbid somatic illnesses and premature mortality, but despite this increased risk, general health care needs in this population are often neglected. Over recent years, several groups have developed screening and monitoring guidelines for metabolic and cardiovascular risk assessment in patients treated with antipsychotics. The psychiatrist needs to be aware of the potential metabolic side-effects of antipsychotic medication and to include them in the risk/benefit assessment when choosing a specific antipsychotic. He should also be responsible for the implementation of the necessary screening assessments and referral for treatment of any physical illness. Multidisciplinary assessment of psychiatric and medical conditions is needed. The somatic treatments offered to people with severe and enduring mental illness should be at par with general health care in the non-psychiatrically ill population. In our University Centre, a structured and elaborate screening and monitoring protocol was introduced in late 2003. This paper describes the practical aspects of this monitoring protocol and the results obtained 4 years after its implementation.
