Summary Introduction Hyperprolactinemia is a common side-effect of antipsychotic treatment. Antipsychotics and hyperprolactinemia are both considered risk factors of metabolic disturbances and diabetes. Investigations on prolactin response to meal ingestion in antipsychotic-treated patients are missing. Material and methods In a case-control design, 49 antipsychotic-treated, clinically stable, non-diabetic, schizophrenia spectrum male patients were compared with 93 healthy male controls by age (33.1, SD 7.4 vs. 32.9, SD 6.6 years), body mass index (26.2, SD 4.6 vs. 26.1, SD 3.9 kg/m 2 ) and waist circumference (96.4, SD 13.0 vs. 96.7, SD 11.9 cm). Serum-prolactin was measured in the morning and 90 min after ingestion of a standardized liquid meal (2268 kJ). Results Fasting prolactin levels varied considerably, and mean fasting prolactin levels did not significantly differ between patients and controls (12.33, SD 11.58 vs. 10.06, SD 8.67 ng/ml, p = 0.623). In the controls, postprandial serum prolactin was significantly reduced ( Δ −2.53, SD 9.75 ng/ml, p = 0.016). In antipsychotic-treated patients postprandial serum prolactin tended to increase ( Δ 2.62, SD 10.96 ng/ml, p = 0.081). Analyses of subgroups based on the prolactinogenic liability of their antipsychotic treatment indicated 22 to 65% higher postprandial prolactin levels with high and intermediate prolactinogenic antipsychotics. Discussion A physiological postprandial suppression of serum prolactin appears absent in antipsychotic-treated males. Marked variability in fasting prolactin levels may reflect individual variations in the diurnal cycle. Uniform acquisition procedures accounting for diurnal variation and food intake may enhance reliability of prolactin levels in antipsychotic-treated male patients.

OBJECTIVE Treatment with antipsychotic drugs is widely associated with metabolic side effects such as weight gain and disturbed glucose metabolism, but the pathophysiologic mechanisms are unclear. METHOD Fifty nondiabetic (fasting plasma glucose ≤ 7.0 mmol/L), antipsychotic-treated male patients (ICD-10 diagnosis code F20, F21, F22, F25, F28, or F60; mean ± SD age = 33.0 ± 6.7 years; body mass index [BMI; kg/m²] = 26.0 ± 4.7; waist circumference = 95.9 ± 13.3 cm; glycated hemoglobin A1c [HbA1c] = 5.7% ± 0.3%) and 93 age- and waist circumference-matched healthy male controls (age = 33 ± 7.3 years; BMI = 26.1 ± 3.9; waist circumference = 94.6 ± 11.9 cm; HbA1c = 5.7% ± 0.3%) participated in this cross-sectional study. Blood was sampled in the fasting state and 90 minutes after ingestion of a standardized liquid meal (2,268 kJ). The primary outcomes were glucometabolic hormones and cardiovascular risk markers. Data were collected between March 2008 and February 2010. RESULTS Compared to healthy controls, patients were characterized by elevated fasting levels of proinsulin, C-peptide, and glucose-dependent insulinotropic polypeptide (GIP) (P < .05) and higher postprandial levels of insulin, proinsulin, C-peptide, and GIP (P ≤ .02). Also, patients exhibited elevated plasma levels of C-reactive protein and signs of dyslipidemia. Fasting plasma levels of insulin, glucagon, glucagon-like peptide-1 (GLP-1), ghrelin, leptin, adiponectin, tumor necrosis factor-α, plasminogen activator inhibitor-1, and interleukin-6 and postprandial levels of glucagon, GLP-1, ghrelin, leptin, and adiponectin did not differ between groups. CONCLUSIONS Presenting with an insulin resistant-like pattern, including beta cell hypersecretion and elevated GIP levels, nondiabetic antipsychotic-treated patients display emerging signs of dysmetabolism and a compromised cardiovascular risk profile. The appetite-regulating hormones GLP-1 and ghrelin appear not to be influenced by antipsychotic treatment. Our findings provide new clinical insight into the pathophysiology associated with metabolic side effects of antipsychotic treatment and put emphasis on the importance of implementing metabolic screening into psychiatric practice.

Background Various schizophrenic symptoms are suggested to be linked to a dysfunction of the brain reward system. Several studies have found alterations in the reward processing in patients with schizophrenia; however, most previous findings might be confounded by medication effects. Methods Thirty-one antipsychotic-naive schizophrenia patients and 31 age- and gender-matched healthy control subjects were examined with functional magnetic resonance imaging while playing a variant of the monetary incentive delay task. The task variant made it possible to separate overall salience (defined as arousing events) into behavioral salience (events where a predicted reward requires performance) and valence anticipation (the anticipation of a monetarily significant outcome) . Furthermore, the evaluation of monetary gain and loss was assessed. Results During reward anticipation, patients had a significant attenuation of the activation in ventral tegmentum, ventral striatum, and anterior cingulate cortex during presentation of salient cues. This signal attenuation in ventral striatum was correlated with the degree of positive symptoms. Signal attenuation was most pronounced for behavioral salience and nonsignificant for value anticipation. Furthermore, patients showed a changed activation pattern during outcome evaluation in right prefrontal cortex. Conclusion Our results suggest that changes during reward anticipation in schizophrenia are present from the beginning of the disease. This supports a possible involvement of reward disturbances in the pathophysiology of schizophrenia. The most pronounced changes were seen in relation to overall salience. In ventral striatum these changes were associated with the degree of positive symptoms.

Nielsen J, Damkier P, Lublin H, Taylor D. Optimizing clozapine treatment. Objective: Clozapine treatment remains the gold standard for treatment-resistant schizophrenia, but treatment with clozapine is associated with several side-effects that complicate the use of the drug. This clinical overview aims to provide psychiatrists with knowledge about how to optimize clozapine treatment. Relevant strategies for reducing side-effects and increasing the likelihood of response are discussed. Method: Studies of clozapine available in MEDLINE were reviewed. Results: A slow up-titration of clozapine is recommended in order to reach the optimal dosage of clozapine and diminish the risk of dose-dependent side-effects. Particularly, in case of partial response or non-response, the use of therapeutic drug monitoring of clozapine is recommended. Plasma levels above the therapeutic threshold of 350–420 ng/ml are necessary to determine non-response to clozapine. To ease the burden of dose-dependent side-effects, dose reduction of clozapine should be tried and combination with another antipsychotic drug may facilitate further dose reduction. For most side-effects, counteracting medication exists. Augmentation with lamotrigine, antipsychotics, or electroconvulsive therapy may be beneficial in case of partial response to clozapine. Conclusion: Treatment with clozapine should be optimized in order to increase the rate of response and to minimize side-effects, thus diminishing the risk of discontinuation and psychotic relapse.

OBJECTIVE The pharmacologic treatment of schizophrenia is characterized by excessive use of antipsychotic polypharmacy, which reflects a gap between evidence and practice. The aim of the present study was to investigate regional differences in treatment setting characteristics and in physician and nurse attitudes toward antipsychotic polypharmacy and clinical guidelines. METHOD Cross-sectional postal questionnaire survey directed to physicians and nurses at 2 pairs of treatment settings in Denmark, characterized by low and high prevalence of antipsychotic polypharmacy, respectively. The questionnaire investigation was conducted during November 2007 to February 2008. RESULTS Satisfactory response rates were obtained (physicians: 93%; nurses: 87%). The treatment settings with low use of antipsychotic polypharmacy were characterized by raised knowledge/awareness of local antipsychotic treatment guidelines (P = .02 for physicians; P = .01 for nurses). Among physicians, these settings were also characterized by an elevated confidence in these guidelines (P = .01), frequent local educational activities (P < .0001), and increased recent involvement in research (P = .01). Among nurses, a perception of an overwhelming work load (P = .01) and time pressure (P = .003) was significantly more prevalent in treatment settings with high rates of antipsychotic coprescribing, as was the belief in the benefit of antipsychotic polypharmacy augmentation (P = .001). CONCLUSION Albeit no causal relationships can be inferred from this cross-sectional observational study, we recommend the furtherance of a treatment environment characterized by easily accessible clinical guidelines, frequent academic activities, and an unruffled atmosphere.

First-generation antipsychotics have been associated with striatal volume increases. The effects of second-generation antipsychotics (SGAs) on the striatum are unclear. Moreover, SGAs may have neuroprotective effects on the hippocampus. Dose-dependent volumetric effects of individual SGAs have scarcely been investigated. Here we investigated structural brain changes in antipsychotic-naive, first-episode schizophrenia patients after 6 months treatment with the SGA, quetiapine. We have recently reported on baseline volume reductions in the caudate nucleus and hippocampus. Baseline and follow-up T1-weighted images (3 T) from 22 patients and 28 matched healthy controls were analysed using tensor-based morphometry. Non-parametric voxel-wise group comparisons were performed. Small volume correction was employed for striatum, hippocampus and ventricles. Dose-dependent medication effects and associations with psychopathology were assessed. Patients had significant bilateral striatal and hippocampal loss over the 6-month treatment period. When compared to controls the striatal volume loss was most pronounced with low quetiapine doses and less apparent with high doses. Post-hoc analyses revealed that the striatal volume loss was most pronounced in the caudate and putamen, but not in accumbens. Conversely, hippocampal volume loss appeared more pronounced with high quetiapine doses than with low doses. Clinically, higher baseline positive symptoms were associated with more striatal and hippocampal loss over time. Although patients' ventricles did not change significantly, ventricular increases correlated with less improvement of negative symptoms. Progressive regional volume loss in quetiapine-treated, first-episode schizophrenia patients may be dose-dependent and clinically relevant. The mechanisms underlying progressive brain changes, specific antipsychotic compounds and clinical symptoms warrant further research.

We have previously reported decreased frontal cortical serotonin2A receptor binding in 30 antipsychotic naïve first-episode schizophrenic patients and a relationship between this binding and positive psychotic symptoms. Until now, no longitudinal studies of serotonin2A receptor in first-episode antipsychotic-naïve schizophrenia patients have reported on the relationship between serotonin2A receptor occupancy and treatment effect after sustained treatment with a specific atypical antipsychotic compound.Here, we measured serotonin2A receptor occupancy with [(18)F]altanserin PET in 15 first-episode antipsychotic-naïve schizophrenia patients before and after 6 months of quetiapine treatment. Moreover, we investigated possible relationships between clinical efficacy, oral dose, and plasma levels of quetiapineSignificant nonlinear relationships were found between serotonin2A receptor occupancy, quetiapine dose, and plasma concentration. There was a modest effect on positive symptoms up until a serotonin2A receptor occupancy level of approximately 60%. A receptor occupancy level between 60% and 70% appeared to exert the optimal serotonin2A receptor related treatment effect on positive symptoms whereas no additional serotonin2A receptor associated treatment effect was obtained above a receptor occupancy of 70%.Taken together, the data point to a therapeutic role of the serotonin2A receptor in the treatment of subgroups of patients with schizophrenia. Specifically, the study indicates a serotonin2A receptor associated therapeutic window on positive symptoms in responding patients in the range between 60% and 70% occupancy in antipsychotic-naïve first-episode schizophrenia. We speculate that non-responding patients need higher dopamine D(2) receptor blockade. Future studies with concurrent measurement of interactions with the dopamine system are, however, warranted to clarify this.

Baandrup L, Allerup P, Lublin H, Nordentoft M, Peacock L, Glenthoj B. Evaluation of a multifaceted intervention to limit excessive antipsychotic co-prescribing in schizophrenia out-patients. Objective: To evaluate the effect of a multifaceted educational intervention on the frequency of antipsychotic co-prescribing in adult schizophrenia out-patients. Method: Controlled quasi-experimental study performed in two Danish municipalities matched for baseline prevalence of antipsychotic polypharmacy, socioeconomic status and functional level of patients. The intervention was aimed at psychiatric healthcare providers and consisted of 1 day of didactic lectures, six 3-h educational outreach visits and an electronic reminder during drug prescribing. Results: Between-group use of antipsychotic polypharmacy was compared at baseline (intervention group, N = 232/control group, N = 351) and after 1 year of intervention (intervention group, N = 216/control group, N = 386). The prevalence of antipsychotic polypharmacy at follow-up was not significantly different between treatment settings when adjusting for differences in case-mix (P = 0.07). Conclusion: This multifaceted educational intervention failed to reduce the frequency of antipsychotic co-prescribing, but it suggested that future efforts to improve prescribing practice should address organizational barriers to implementation.

Background: Enlarged ventricles and reduced hippocampal volume are consistently found in patients with first-episode schizophrenia. Studies investigating brain structure in antipsychotic-naive patients have generally focused on the striatum. In this study, we examined whether ventricular enlargement and hippocampal and caudate volume reductions are morphological traits of antipsychotic-naive firstepisode schizophrenia. Methods: We obtained high-resolution 3-dimensional T1-weighted magnetic resonance imaging scans for 38 antipsychotic-naive first-episode schizophrenia patients and 43 matched healthy controls by use of a 3-T scanner. We warped the brain images to each other by use of a high-dimensional intersubject registration algorithm. We performed voxel-wise group comparisons with permutation tests. We performed small volume correction for the hippocampus, caudate and ventricles by use of a false discovery rate correction (p < 0.05) to control for multiple comparisons. We derived and analyzed estimates of brain structure volumes. We grouped patients as those with (n = 9) or without (n = 29) any lifetime substance abuse to examine the possible effects of substance abuse. Results: We found that hippocampal and caudate volumes were decreased in patients with first-episode schizophrenia. We found no ventricular enlargement, differences in global volume or significant associations between tissue volume and duration of untreated illness or psycho pathology. The hippocampal volume reductions appeared to be influenced by a history of substance abuse. Exploratory analyses indicated reduced volume of the nucleus accumbens in patients with first-episode schizophrenia. Limitations: This study was not a priori designed to test for differences between schizophrenia patients with or without lifetime substance abuse, and this subgroup was small. Conclusion: Reductions in hippocampal and caudate volume may constitute morphological traits in antipsychotic-naive first-episode schizophrenia patients. However, the clinical implications of these findings are unclear. Moreover, past substance abuse may accentuate hippocampal volume reduction. Magnetic resonance imaging studies addressing the potential effects of substance abuse in antipsychoticnaive first-episode schizophrenia patients are warranted.

Twentyfour male patients with sustained myocardial infarction (MI) were studied with 12-lead ECG and systolic time intervals (STI) 5 months after the acute episode. From the ECGs were calculated the summed voltages of the R wave (sigma R), the Q wave (sigma Q), and the ST segment deviation (sigma ST). These ischaemic ECG variables were correlated with the STI parameters of left ventricular function: LVETI, PEP and PEP/LVET. Statistically significant regression equations relating the ECG changes to the STI variables were found in anterior MI, for sigma ST in the entire series, but not in inferior MI. Thus a simple and rapid inspection of the resting 12-lead ECG gives an indirect but reliable quantitative estimate of left ventricular function in patients with a sustained myocardial infarction.

ResumenAntecedentes.Los ensayos naturalistas sobre la efectividad de los antipsicóticos atípicos son necesarios para aportar una información más amplia sobre la eficacia, la seguridad y la tolerabilidad en pacientes con esquizofrenia tratados en un centro médico de la comunidad.Métodos.En este estudio multicéntrico abierto de 26 semanas, diversos pacientes con esquizofrenia, que necesitaron un cambio en la medicación antipsicótica porque no toleraban bien la medicación actual y/o porque los síntomas clínicos no estaban bien controlados, se aleatorizaron para recibir aripiprazol o un tratamiento estándar (TE) con un antipsicótico atípico (por ejemplo, olanzapina, quetiapina o risperidona en función del juicio del investigador sobre el tratamiento óptimo de cada paciente individual y la respuesta previa del paciente a la medicación antipsicótica). El objetivo principal fue comparar la efectividad de un tratamiento de 26 semanas con aripiprazol con el TE, medido por la puntuación total del Cuestionario de Evaluación del Investigador (IAQ) en la última observación arrastrada (UOA) de la semana 26 (variable primaria), una medida validada que controla el alivio o el empeoramiento de 10 síntomas clave asociados con la psicopatología de la esquizofrenia y los efectos secundarios del tratamiento antipsicótico. Los objetivos secundarios fueron evaluar la efectividad usando las escalas Impresión Clínica Global - Mejoría Global (CGI-I) e Impresión Clínica Global - Gravedad de la Enfermedad, para evaluar el tiempo transcurrido hasta la suspensión del tratamiento, la preferencia del paciente respecto a la medicación, y la calidad de vida y la tolerabilidad de aripiprazol comparado con el TE.Resultados.El tratamiento con aripiprazol (n=268) fue significativamente más eficaz que el TE (n = 254; P < 0,001; UOA de la semana 26), evidenciado por la puntuación IAQ total, desde la semana 4 (primera fase de evaluación) y se mantuvo hasta la semana 26. Una relación similar se demostró en los pacientes que terminaron el estudio (análisis de casos observados); aripiprazol se asoció con una efectividad significativamente mayor en todas las fases de evaluación con un mayor efecto diferencial de TE con el tiempo. Los pacientes tratados con aripiprazol también tuvieron mejorías significativamente mayores en la escala CGI-I (tasa de rspuesta, P = 0,009 en la UOA de la semana 26), y en la calidad de vida (puntuación total en la escala de Calidad de Vida; P < 0,001 en la semana 26). Además, una proporción significativamente mayor de pacientes que recibieron aripiprazol calificaron la medicación del estudio como “mucho mejor” en la escala del Cuestionario de Preferencias de Medicación (POM) que la medicación anterior al estudio comparados con los pacientes tratados con TE (P < 0,001; semana 26). El tiempo hasta la suspensión del tratamiento y las tasas de suspensión debidas a episodios adversos fueron similares en los dos grupos de tratamiento. La incidencia de pacientes con uno o varios síntomas extrapiramidales (por ejemplo, acatisia, distonía, episodios parkinsonianos y episodios residuales) fue mayor en los pacientes que recibieron aripiprazol comparados con los pacientes tratados con TE (13,5% frente a 5,6%); sin embargo, una proporción mayor de pacientes del grupo TE tuvo un aumento de peso clínicamente significativo (21,2% frente a 7,3% para aripiprazol) y de las concentraciones séricas (potencialmente importantes desde el punto de vista clínico) de colesterol total, colesterol de lipoproteínas de baja densidad, triglicéridos y prolactina comparados con los pacientes que recibieron aripiprazol.Conclusiones.Aripiprazol es un antipsicótico atípico eficaz para el tratamiento de la esquizofrenia, que ha demostrado más efectividad que los fármacos estándar usados en este estudio en pacientes que necesitaban un cambio en la medicación antipsicótica.

The 32-bp deletion allele in chemokine receptor CCR5 has been associated with several immune-mediated diseases and might be implicated in schizophrenia as well.The authors genotyped DNA samples from 268 schizophrenia patients and 323 healthy subjects. Age at first admission to a psychiatric hospital department served as a measure of disease onset.Patients and comparison subjects differed marginally in their genotype distribution, with a slightly higher frequency of the deletion allele seen in the patients. The authors found the deletion allele to be associated with higher age at first admission. After age at first admission was analyzed as a continuous variable, it was dichotomized using 40 years as the cutoff. With this approach the authors found that genotype distributions of patients with age at first admission above the cutoff (possible cases of late-onset schizophrenia) and healthy subjects differed significantly. This was reflected in an increased frequency of the deletion allele in the patient subgroup. Patients with ages at first admission below and above 40 years significantly differed in distribution of genotypes and alleles, with an overrepresentation of the deletion allele in the latter subgroup of patients.These findings suggest that the CCR5 32-bp deletion allele is a susceptibility factor for schizophrenia with late onset. Alternatively, the CCR5 32-bp deletion allele may act as a modifier by delaying the onset of schizophrenia without affecting the disease susceptibility.

This review discusses the atypical antipsychotics, focusing on the possibility of symptom reduction with a minimum of side-effects. A selective review of clinically relevant reports, studies and meta-analyses is presented. The results from clinical trials suggest that atypical agents improve negative and affective symptoms, and cognitive functioning more than typical antipsychotics, but that the pattern of effects on these domains, as well as on suicidality, appears to differ. In clinical trials, the newer drugs generally have less extrapyramidal side-effects (EPS) than typical antipsychotics. However, amisulpride, risperidone, olanzapine and ziprasidone still show evidence of a dose-related increase in EPS, whereas clozapine, quetiapine, sertindole and aripiprazole do not. Weight gain, increased blood lipids/cholesterol, and insulin resistance/type 2 diabetes are emerging as significant treatment-associated concerns, particularly for clozapine and olanzapine. Sedation has been reported for all the newer compounds except sertindole. The considerable variation in benefit/risk profiles of the atypical compounds can help the clinician to select the most appropriate treatment for individual patients.

Objective: To evaluate the long-term effectiveness of the second generation antipsychotics, risperidone and olanzapine on hospitalization, clinical response, and adherence to therapy after switching from conventional antipsychotics or clozapine in a naturalistic setting of schizophrenic patients. Method: Data were registered for periods of identical duration before and after switching. Results: Fifty-seven patients were included. Mean study period was 3.1 ± 0.2 years. Mean number of in-patient days after switching declined by 78% of the level before switching (P=0.0002). There was no significant differences in ratio responders/non-responders between the subgroups. The number of patients with extrapyramidal symptoms (EPS) was significantly reduced after switching. However, intolerable weight gain led to a lack of adherence to therapy in 18% of the olanzapine-treated patients. Conclusion: Long-term treatment with the second generation antipsychotics, risperidone and olanzapine significantly improved the clinical outcome. However, weight gain may be a significant reason for discontinuation of treatment and reducing the long-term adherence to therapy.

Objective: QT interval (QTi) prolongation is generally associated with increased risk of ventricular arrhythmias such as torsade de pointes (TdP) and death. Method: Literature review based on publications identified by means of electronic and manual search. Results: It has recently become apparent that not only antiarrhythmic drugs such as sotalol and quinidine, but also a variety of non-antiarrhythmic drugs such as certain antihistamines, antimicrobial drugs, psychiatric drugs and cisapride, may have the ability to induce prolongation of the QTi and TdP. Special concern should be drawn to the coadministration of drugs that inhibit the metabolism of these drugs such as ketoconazole, itraconazol and erythomycin. Patients with congenital long QT syndrome, patients with heart disease, with hypokalemia or hypomagnesemia, and women have an increased risk. Every sign of dizziness or syncope should be regarded as a warning sign of possible arrhythmia in patients treated with drugs that potentially prolong the QTi. Conclusion: Measurement of the QTi before and during treatment is generally recommended in high-risk patients.

In schizophrenic patients in maintenance treatment, clozapine, compared to classic neuroleptics, induces relatively few extrapyramidal syndromes (EPS), especially less akathisia and tremor and usually no dystonia or rigidity. In patients with dyskinetic movements (acute or tardive) induced by other neuroleptics, clozapine may reduce or even remove dyskinesia or permit it to disappear. It cannot, however, be excluded that clozapine can induce dyskinesia in extremely rare cases, but it seems more likely that this is due to previous treatment with classic neuroleptics. The earlier clozapine is started, the less chance of development of dyskinesia. The low level of EPS with clozapine may be linked to the special receptor-binding profile of this drug: during treatment with therapeutic doses of clozapine, the level of D2 receptor blockade is too low (40% to 50% occupancy by positron emission tomography) to induce EPS, and the D1 receptor blockade (also 40% to 50% occupancy) has a lower EPS potential than D2 blockade. This binding profile may at the same time contribute to the special antipsychotic properties of clozapine. Other receptor affinities may contribute to the beneficial effect of clozapine in EPS and schizophrenia.

CONTEXT Schizophrenic symptoms are linked to a dysfunction of dopamine neurotransmission and the brain reward system. However, it remains unclear whether antipsychotic treatment, which blocks dopamine transmission, improves, alters, or even worsens the reward-related abnormalities. OBJECTIVE To investigate changes in reward-related brain activations in schizophrenia before and after antipsychotic monotherapy with a dopamine D2/D3 antagonist. DESIGN Longitudinal cohort study. SETTING Psychiatric inpatients and outpatients in the Capital Region of Denmark. PARTICIPANTS Twenty-three antipsychotic-naive patients with first-episode schizophrenia and 24 healthy controls initially matched on age, sex, and parental socioeconomic status were examined with functional magnetic resonance imaging while playing a variant of the monetary incentive delay task. INTERVENTIONS Patients were treated for 6 weeks with the antipsychotic compound amisulpride. Controls were followed up without treatment. MAIN OUTCOME MEASURES Task-related blood oxygen level-dependent activations as measured by functional magnetic resonance imaging before and after antipsychotic treatment. RESULTS At baseline, patients, as compared with controls, demonstrated an attenuation of brain activation during reward anticipation in the ventral striatum, bilaterally. After 6 weeks of treatment, patients showed an increase in the anticipation-related functional magnetic resonance imaging signal and were no longer statistically distinguishable from healthy controls. Among the patients, there was a correlation between the improvement of positive symptoms and normalization of reward-related activation. Those who showed the greatest clinical improvement in positive symptoms also showed the greatest increase in reward-related activation after treatment. CONCLUSIONS To our knowledge, this is the first controlled, longitudinal study of reward disturbances in schizophrenic patients before and after their first antipsychotic treatment. Our results demonstrate that alterations in reward processing are fundamental to the illness and are seen prior to any treatment. Antipsychotic treatment tends to normalize the response of the reward system; this was especially seen in the patients with the most pronounced treatment effect on the positive symptoms.

Background Antipsychotic-induced weight gain constitutes a major unresolved clinical problem which may ultimately be associated with reducing life expectancy by 25 years. Overweight is associated with brain deterioration, cognitive decline and poor quality of life, factors which are already compromised in normal weight patients with schizophrenia. Here we outline the current strategies against antipsychotic-induced weight gain, and we describe peripheral and cerebral effects of the gut hormone glucagon-like peptide-1 (GLP-1). Moreover, we account for similarities in brain changes between schizophrenia and overweight patients. Discussion Current interventions against antipsychotic-induced weight gain do not facilitate a substantial and lasting weight loss. GLP-1 analogs used in the treatment of type 2 diabetes are associated with significant and sustained weight loss in overweight patients. Potential effects of treating schizophrenia patients with antipsychotic-induced weight gain with GLP-1 analogs are discussed. Conclusions We propose that adjunctive treatment with GLP-1 analogs may constitute a new avenue to treat and prevent metabolic and cerebral deficiencies in schizophrenia patients with antipsychotic-induced weight gain. Clinical research to support this idea is highly warranted.

Clozapine augmentation with antipsychotic drugs is widely used despite sparse evidence supporting this strategy. Sertindole is a nonsedating atypical antipsychotic drug with low affinity for cholinergic receptors, which makes it potentially suitable for augmentation of clozapine. The study design was a 12-week, double-blind, randomized, placebo-controlled study including patients with International Statistical Classification of Diseases, 10th Revision schizophrenia (F20.0-F20.3) and treated with clozapine for at least 6 months who had not achieved sufficient response. Patients were randomized 1:1 to either sertindole 16 mg or placebo, and assessment was done at baseline and after 6 and 12 weeks. Assessment included the Positive and Negative Syndrome Scale, Clinical Global Impression, Udvalg for Kliniske Undersøgelser, World Health Organization Quality of Life Brief, Drug Attitude Inventory, fasting glucose, lipids, and electrocardiogram. Clozapine augmentation with sertindole was not superior to placebo regarding total score or subscale score of the Positive and Negative Syndrome Scale, Clinical Global Impression, World Health Organization Quality of Life Brief, or Drug Attitude Inventory. No increased adverse effects compared with placebo were found. Four patients randomized to sertindole experienced a significant worsening of psychosis, and 2 of them required psychiatric admission. Metabolic parameters were unchanged during the study, but augmentation of clozapine with sertindole was associated with a 12-millisecond (SD, 20-millisecond) QTc prolongation compared with 0 millisecond (SD, 20 milliseconds) in the placebo group (P

Experience of 32 cases of symphysiotomy carried out in Mozambique and in Botswana is reviewed. Of all cases only 1 was lost to follow-up. The observation period varied from 7 days to 6 months. Among 31 cases examined at discharge or on return from check-up few complications occurred. Vaginal laceration occurred in 3 cases, haematuria in 1 case and wound infection in 1 case. In 2 cases there was significant postoperative pain causing gait problems, but in no case were there significant problems with pain at discharge or at follow-up. It is concluded that the intervention is seldom complicated by severe sequelae, provided strict adherence to given indications is respected. In rural areas in the third world symphysiotomy is a life-saving and simple surgical intervention, which should be regarded as an adjunct measure in some cases with a moderately contracted pelvic outlet incompatible with normal vaginal delivery.

Impaired prepulse inhibition of the startle reflex (PPI) in schizophrenia has been replicated in many studies. However, previous results may have been influenced by course of illness, and antipsychotic medication. Studies on antipsychotic-naive, first-episode schizophrenia patients are lacking, since these patients are so difficult to recruit. Furthermore, longitudinal studies are few, and their results are inconsistent: some results indicating a reduction of PPI deficits by treatment with atypical antipsychotics, while others do not. This study reports on PPI, habituation and sensitization of the human startle reflex in a large group of antipsychotic-naive, first-episode schizophrenia patients, and the effect of subsequent treatment with quetiapine. Thirty-four antipsychotic-naive, first-episode schizophrenia patients (24 males, 10 females), and age- and gender-matched healthy controls were tested in a psychophysiological test battery at baseline and again after 6 months. During this period, the patients were treated with quetiapine, while the controls received no treatment. Sixteen patients completed the study. At baseline, male patients showed significantly lower PPI than controls. Treatment with quetiapine for 6 months increased male PPI to a level where it was no longer statistically different from the controls. The much smaller group of females did not show PPI deficits at baseline. In addition, compared to controls, patients appeared highly aroused and showed a strong yet non-significant trend for reduced sensitization at baseline, but not at follow-up. Patients and controls showed similar levels of habituation, both at baseline, and at follow-up. These findings indicate that PPI deficits are already present from the earliest stage of clinical onset of schizophrenia, before the patients have received any antipsychotic treatment. In addition, following 6 months' treatment with quetiapine these PPI deficits were normalized. Furthermore, the results suggest that schizophrenia patients in the antipsychotic-naive state show reduced levels of sensitization, yet normal levels of habituation.

Clozapine is, in most countries, underutilized and the initiation of clozapine is often delayed. The purpose of this study is to investigate the reasons for the delay and the underutilization of clozapine. One hundred psychiatrists were interviewed by phone. The interview was a structured interview with questions regarding attitude to, knowledge of and experiences with clozapine. Forty-eight (48%) psychiatrists had treatment responsibility of fewer than five patients treated with clozapine and 31 of the interviewed psychiatrists (31%) had started clozapine within the last 3 months. Seven psychiatrists (7%) had never prescribed clozapine despite the fact that they had been working more than five years in general psychiatry. Sixty-four psychiatrists (64%) would rather combine two antipsychotics than use clozapine. Sixty-six psychiatrists (66%) believed that patients treated with clozapine were less satisfied with their treatment when compared with those treated with other atypical antipsychotics. Many psychiatrists are reluctant to use clozapine and this might be due to less experience and knowledge of clozapine. A reason for the low awareness of clozapine’s properties might be that clozapine is now a generic drug, and therefore, the marketing and education in using the drug is sparse.

This case report describes a 36-year-old schizophrenic man who developed malignant catatonia during a hospital stay. He was treated with benzodiazepines (BZD) and 26 sessions of electroconvulsive therapy (ECT). After the therapy his condition normalised. Malignant catatonia is a rare condition that develops quickly and fulminantly and is fatal within a few days. ECT treatment is crucial, but despite aggressive treatment the prognosis remains poor.

Postmortem investigations and the receptor affinity profile of atypical antipsychotics have implicated the participation of serotonin(2A) receptors in the pathophysiology of schizophrenia. Most postmortem studies point toward lower cortical serotonin(2A) binding in schizophrenic patients. However, in vivo studies of serotonin(2A) binding report conflicting results, presumably because sample sizes have been small or because schizophrenic patients who were not antipsychotic-naive were included. Furthermore, the relationships between serotonin(2A) binding, psychopathology, and central neurocognitive deficits in schizophrenia are unclear.To assess in vivo brain serotonin(2A) binding potentials in a large sample of antipsychotic-naive schizophrenic patients and matched healthy controls, and to examine possible associations with psychopathology, memory, attention, and executive functions.Case-control study.University hospital, Denmark.A sample of 30 first-episode, antipsychotic-naive schizophrenic patients, 23 males and 7 females, and 30 matched healthy control subjects.Positron emission tomography with the serotonin(2A)-specific radioligand fluorine 18-labeled altanserin and administration of a neuropsychological test battery.Binding potential of specific tracer binding, scores on the Positive and Negative Syndrome Scale, and results of neuropsychological testing.Schizophrenic patients had significantly lower serotonin(2A) binding in the frontal cortex than did control subjects. A significant negative correlation was observed between frontal cortical serotonin(2A) binding and positive psychotic symptoms in the male patients. No correlations were found between cognitive functions and serotonin(2A) binding.The results suggest that frontal cortical serotonin(2A) receptors are involved in the pathophysiology of schizophrenia.clinicaltrials.gov Identifier: NCT00207064.

To investigate the association of antipsychotic polypharmacy in schizophrenia with cost of primary and secondary health service use. Comparative analysis of health service cost for patients prescribed antipsychotic polypharmacy versus antipsychotic monotherapy. Resource utilisation and costs were described using central Danish registers for a 2 year period (2007–2008). We included patients attached to one of two Danish psychiatric referral centres in 1 January 2008 and/or 1 January 2009. Their prescribed treatment with either antipsychotic polypharmacy or monotherapy at the two cross-sectional dates was recorded and used as proxy of polypharmacy exposure during the preceding year. A multivariate generalised linear model was fitted with total costs of primary and secondary health service use as dependent variable, and antipsychotic polypharmacy, diagnosis, age, gender, disease duration, psychiatric inpatient admissions, and treatment site as covariates. The sample consisted of 736 outpatients with a diagnosis in the schizophrenia spectrum. Antipsychotic polypharmacy was associated with significantly higher total health service costs compared with monotherapy (2007: 25% higher costs; 2008: 17% higher costs) when adjusting for potential confounders and risk factors. A subgroup analysis suggested that the excessive costs associated with antipsychotic polypharmacy were partly accounted for by the functional level of the patients. The results demonstrate that antipsychotic co-prescribing is associated with increased use of health care services, even though no causal relations can be inferred from an observational study.

Animal data suggest that a D1 antagonistic component in neuroleptic drugs counteracts development of dopamine supersensitivity and of tolerance to cataleptic effect. This has led to the hypothesis that neuroleptics with D1 antagonistic activity should cause a better suppression of tardive dyskinesia (TD) and less rebound aggravation after withdrawal than pure D2 antagonists. In this study the effect of zuclopenthixol (mixed D1/D2 antagonist) and haloperidol (D2 antagonist) was evaluated in chronic psychotic patients with TD. Fifteen patients completed a randomized crossover study with blind evaluation of TD and parkinsonism. The test medications, haloperidol and zuclopenthixol, caused a significant suppression of TD and a significant increase of parkinsonism. No significant differences between haloperidol and zuclopenthixol were observed. No TD aggravation was seen. The lack of differences between the mixed D1/D2 antagonist and a D2 antagonist suggest that tolerance and DA supersensitivity play no or a minor role for development of TD.

Schizophrenia is a complex disease. A more complete understanding of its neurobiology has been hampered by the fact that most data have been based on studies of patients diagnosed according to either the ICD-10 or the DSM-IV, i.e. patients suffering from pathogenetically different diseases. In recent years, some research projects have attempted to take this into account by focusing on biologically more valid endophenotypes. The current brief review summarises central functional, neurochemical, and structural endophenotypes - and where possible also link these endophenotypes to each other.

Antipsychotic medication has been used for more than fifty years and has brought a dramatic improvement in the treatment of psychotic diseases by removing or reducing the psychotic symptoms and thereby also allowing other treatment approaches to be used. However, an urgent need remains for new medications with better efficacy, especially to limit the so-called negative symptoms and cognitive deficits often observed in schizophrenic patients and to reduce the occurrence of side effects.

The efficacy, safety and tolerability of ziprasidone versus the comparators olanzapine, risperidone or quetiapine were investigated in adult patients with chronic schizophrenia, schizoaffective and schizophreniform disorders, with lack of efficacy or intolerance to their previous antipsychotic treatment based on clinical judgement of the investigator. A total of 293 patients were randomized to 12 weeks treatment with either ziprasidone 80-160 mg/day (n=147) or with one of the comparator drugs (n=146). In the latter group the investigator could choose between olanzapine 10-20 mg/day (n=24), risperidone 4-8 mg/day (n=22) or quetiapine 300-750 mg/day (n=97). The study comprised four visits including a baseline examination prior to randomization and further examinations at the end of weeks 1, 4 and 12. Ziprasidone was non-inferior (defined as a difference of 7 units or less on the PANSS scale to the disadvantage of ziprasidone) to the composite group (olanzapine, risperidone or quetiapine) on the total PANSS score as well as on all subscores (P

The serotonin 5-HT(2A) receptor is suspected to be involved in a number of psychiatric disorders, including schizophrenia. In particular, atypical antipsychotics have antagonistic effects on the 5-HT(2A) receptors, supporting a specific role of the 5-HT(2A) receptor in the pathophysiology of this disease. The aim of this study is to investigate cortical and subcortical 5-HT(2A) binding in neuroleptic-naive schizophrenic patients. Fifteen neuroleptic-naive patients diagnosed with schizophrenia (age 27.5+/-4.5 years), 11 men and 4 women, and 15 healthy control subjects matched for age (28.5+/-5.7 years) and gender underwent a 40 min positron emission tomography (PET) study using the 5-HT(2A) antagonist, [(18)F]altanserin, as a radioligand. PET images were co-registered to 3 T magnetic resonance images (MRIs) for each individual subject, and ROIs were applied automatically onto the individual MRIs and PET images. The cerebellum was used as a reference region. The binding potential of specific tracer binding (BP(p)) was used as the outcome measure. No significant difference was seen in cortical receptor distribution between patients and controls. An increase in 5-HT(2A) receptor binding in the caudate nucleus was detected in the group of schizophrenic patients (0.7+/-0.1) when compared to the healthy controls (0.5+/-0.3) (p=0.02). Our results confirm other in vivo findings of no difference in cortical 5-HT(2A) receptor binding between first-episode antipsychotic-naive schizophrenic patients and age- and gender-matched healthy control subjects. However, a preliminary finding of increased 5-HT(2A) binding in the caudate nucleus requires further investigation to explore the relation of subcortical and cortical 5-HT(2A) receptor binding.

Introduction: The purinergic receptor gene P2RX7 is located in a major linkage hotspot for schizophrenia and bipolar disorders, 12q21–33. It has previously been associated with bipolar disorder but has never been analysed in relation to schizophrenia, although it is involved in several neuronal processes associated with schizophrenia. Methods: Nine functionally characterised variants in P2RX7 were genotyped in 389 patients diagnosed with schizophrenia, each matched on sex, birth-year and month with two healthy controls. Results: We did not find association between P2RX7 and schizophrenia and stratification on gender did not change this result. The high ethnic and diagnostic homogeneity of the sample adds credibility to this finding. Conclusion: P2XR7 was not associated with schizophrenia in this study. © 2008 Elsevier B.V.

The effects of dopamine D1 and D2 receptor agonists and antagonists were studied in eight Cebus apella monkeys previously treated with haloperidol for two years. SKF 81297 (specific D1 receptor agonist) induced oral hyperkinesia of variable intensity (P less than 0.01): some of the monkeys developed extreme lip smacking, tonque protrusions and licking movements while others developed only slight lip movements. A combined treatment of SKF 81297 with LY 171555 (full D2 receptor agonist) or SCH 23390 (D1 receptor antagonist) inhibited the oral hyperkinesia induced by SKF 81297 (P less than 0.01, P less than 0.02, respectively). Raclopride (D2 receptor antagonist) did not statistically change oral hyperkinesia (P less than 0.2), although five monkeys showed increased oral movements; most of these monkeys had pre-existing hyperkinesia. Treatment with SCH 23390 or raclopride resulted in an identical dystonic/cataleptic syndrome. SKF 81297 inhibited the dystonia induced by SCH 23390, while it did not significantly affect raclopride dystonia. The investigation indicates that oral dyskinesia may be related to an imbalance in D1 receptor and D2 receptor stimulation in favor of D1 receptors. The question now is whether D1 receptor antagonists, which may have antipsychotic potential, will produce tardive dyskinesia after long-term use.

Lublin H, Gerlach J. Effect of ketotifen (a histamine antagonist) in tardive dyskinesia in monkeys.Ketotifen (a histamine H-1 antagonist) was given to 8 Cebus monkeys, which previously had received haloperidol for 2 years. Five monkeys had mild tardive dyskinesia. In rodents ketotifen has been shown to reduce haloperidol-induced hypersensitivity. In the present study ketotifen (single dose, 0.5-10.0 mg/kg, and multiple dose, 2 mg × 2/kg/day for 14 days) did not influence tardive dyskinesia. The monkeys were sedated, and locomotor activity was reduced. Ketotifen did not change the effects of haloperidol (a dopamine D-2 antagonist) or apomorphine (a mixed dopamine D-1/D-2 agonist). The results suggest that the only behavioral changes induced by ketotifen were sedation and decreased locomotion, caused by sedation.

To examine the effectiveness of aripiprazole in schizophrenia in a naturalistic setting in 14 European countries.This multicentre, open-label study of aripiprazole evaluated outpatients with schizophrenia for whom a medication switch was clinically reasonable or antipsychotic initiation was required. Patients (n = 833) were randomized in a 4:1 ratio to aripiprazole (recommended starting dose 15 mg/day, permitted adjustment 10-30 mg/day) (n = 680) or another antipsychotic (safety control [SC] group) (n = 153) for 8 weeks. The control group received an antipsychotic different to their recent pre-study medication. The primary effectiveness measure was the Clinical Global Impression - Improvement (CGI - I) score of aripiprazole-treated patients at Week 8 (last observation carried forward [LOCF]). Patients' and caregivers' medication preference was assessed using the Preference of Medication (POM) questionnaire. The Investigator Assessment Questionnaire (IAQ) was used to record investigators' assessments of their patients' responses to the study antipsychotic. Adverse events (AEs) were recorded.At endpoint (Week 8, LOCF), the mean CGI - I score of 3.16 (95% confidence interval, [CI]: 3.04, 3.28) demonstrated the effectiveness of aripiprazole. At endpoint, 43% of aripiprazole-treated patients showed a response (CGI - I score = 1/2). Aripiprazole was rated as slightly or much better than previous antipsychotic at endpoint by 68% of patients and 65% of caregivers. The mean CGI - I score (Week 8, LOCF) for the SC group was 3.37 (95% CI: 3.14, 3.60). No major differences in the occurrence of AEs were noted between aripiprazole- and SC-treated patients.As this is an open-label design, there may have been a bias. Secondly, the study was not powered to show differences between treatment groups and no statistical comparisons were planned. Thirdly, 8 weeks is too short to evaluate long-term effectiveness.Aripiprazole was effective, well tolerated and well accepted by patients and caregivers in this naturalistic study.

The objective of this study was to examine the effects of adjunctive treatment with the acetylcholinesterase inhibitor, donepezil, on cognitive deficits and psychopathology in schizophrenic patients treated with the antipsychotic, ziprasidone. The design of the study was double blind, placebo controlled, and longitudinal. Patients were treated with ziprasidone for 8 weeks, thereafter randomized to 4 months of double-blind adjunctive treatment with either donepezil (dose, 5-10 mg) or placebo. The severity of psychopathology (PANSS) and the cognitive deficits were examined at baseline and after 4 months. A total of 21 schizophrenic patients were enrolled, of whom 11 patients completed the trial (donepezil, n = 7; placebo, n = 4). There were no within- or between-group differences in changes on the Positive and Negative Syndrome Scale scores or a global cognitive score. Within-group improvements (all at trend level P = 0.07) were seen in the placebo group on Trail-Making Test B, immediate verbal recall, and set-shifting errors. The donepezil group showed a significant deterioration on planning efficiency (P = 0.04). Between-group differences were found between the lack of improvement in immediate verbal recall in the donepezil group and the improvement in the placebo group (P = 0.02), and between the deterioration of planning efficiency in the donepezil group and the stability in the placebo group (trend level, P = 0.07). Linear regression analyses showed that neither baseline psychopathology scores, baseline levels of cognitive deficits, nor psychopathology changes over time accounted for these changes in cognitive scores. The study found no evidence of improved cognition after treatment with donepezil, although the conclusions that can be drawn are limited by the small sample size.

BackgroundNaturalistic effectiveness trials of atypical antipsychotics are needed to provide broader information on efficacy, safety, and tolerability in patients with schizophrenia treated in a community practice setting.Methodin this 26-week, open-label, multicentre study, patients with schizophrenia requiring a switch in antipsychotic medication because current medication was not well tolerated and/or clinical symptoms were not well controlled were randomized to receive aripiprazole or an atypical antipsychotic standard of care (SOC) treatment (i.e., olanzapine, quetiapine, or risperidone based on the investigator's judgment of the optimal treatment for the individual patient and the patient's prior response to antipsychotic medication). The primary objective was to compare the effectiveness of a 26-week treatment of aripiprazole versus SOC, as measured by the investigator Assessment Questionnaire (IAQ) total score at Week 26 last observation carried forward (LOCF) (primary endpoint), a validated measure that monitors relief or worsening of 10 key symptoms associated with the psychopathology of schizophrenia and side effects of antipsychotic treatment. Secondary objectives were to further assess effectiveness using the Clinical Global Impression – Global Improvement (CGI-I) and Clinical Global Impression – Severity of Illness scale, to assess time to treatment discontinuation, patient preference of medication, quality of life, and the tolerability of aripiprazole compared with SOC.ResultsAripiprazole treatment (n = 268) resulted in significantly better effectiveness than SOC treatment (n = 254; P < 0.001; Week 26 LOCF) as evidenced by the IAQ total score beginning at Week 4 (the first assessment point) and sustained through Week 26. A similar relationship was demonstrated among patients who completed the study (observed cases analysis); aripiprazole was associated with significantly better effectiveness at all time points with a greater differential effect from SOC over time. Patients treated with aripiprazole also demonstrated significantly greater improvements on the CGI-I scale (responder rate, P = 0.009 at Week 26 LOCF), as well as on quality of life (Quality of Life scale total score; P < 0.001 at Week 26). Furthermore, a significantly higher proportion of patients receiving aripiprazole rated their study medication as “much better” on the Preference of Medication Questionnaire (POM) scale than their pre-study medication compared with SOC patients (P < 0.001; Week 26). Time to treatment discontinuation and rates of discontinuation due to adverse events were similar in both treatment groups. The incidence of patients with one or more extrapyramidal symptom (e.g., akathisia, dystonia, parkinsonian events, and residual events) was higher in patients receiving aripiprazole compared with patients treated with SOC (13.5% vs. 5.6%); however, a higher proportion of patients in the SOC-treated group had clinically significant weight gain (21.2% vs. 7.3% for aripiprazole) and potentially clinically relevant elevated fasting levels of total cholesterol, low-density lipoprotein cholesterol, triglycerides, and serum prolactin compared with patients receiving aripiprazole.ConclusionsAripiprazole is an effective atypical antipsychotic for the treatment of schizophrenia, demonstrating better effectiveness than SOC agents used in this study in patients for whom a switch in antipsychotic medication was warranted.

Today drug therapy of dementia in elderly patients is possible. Owing to a huge increase in the number of elderly people throughout the Western world in the coming years, evidence-based treatment of dementia in this group is needed. The article reviews double-blind, randomized trials on the effect in dementia of donepezil, galantamine, rivastigmine and memantine up to 2003. A total of 27 studies were included. Donepezil, galantamine, rivastigmine and memantine improve cognition and the global level of functioning in mild to moderate Alzheimer's disease (AD). Most evidence exists for donepezil and galantamine. The effect of rivastigmine is best documented in Lewy body dementia (LB). Galantamine, memantine and donepezil may improve cognition in vascular dementia (VD). Galantamine may improve behavioural psychological symptoms of dementia (BPSD). No solid evidence for drug therapy in severe dementia exists. Elderly patients with mild to moderate AD should be offered drug therapy. One should also consider expanding the indication of dementia treatment to LB and VD. An international consensus on what primary efficacy variables to use is needed.

As with the two preceding guidelines of this series, these practice guidelines for the pharmacological maintenance treatment of bipolar disorder were developed by an international task force of the World Federation of Societies of Biological Psychiatry (WFSBP). Their purpose is to supply a systematic overview of all scientific evidence relating to maintenance treatment. The data used for these guidelines were extracted from a MEDLINE and EMBASE search, from recent proceedings from key conferences and various national and international treatment guidelines. The scientific justification of support for particular treatments was categorised into four levels of evidence (A-D). As these guidelines are intended for clinical use, the scientific evidence was not only graded, but also reviewed by the experts of the task force to ensure practicality.

Quality management and quality control of health services has become increasingly important. Central to the concept of quality of care is the patient's (the health care consumer's) own view of the care provided and the treatment outcome. UKU (Udvalg for Kliniske Undersøgelser; that is, Committee for Clinical Trials), a working group within the Scandinavian Society for Psychopharmacology (SSP), has designed a brief consumer satisfaction rating scale, the UKU-ConSat. Based on an extensive literature review, a number of principles related to content, assessment, interview techniques, documentation and standardisation steered the design of the rating scale. UKU-ConSat consists of six items related to the structure and process of treatment care, and two items related to outcome and well-being. A manual accompanies the rating scale with guidelines for how to solicit information from the patient and how to rate each item. A first field trial of the rating scale in 135 inpatients at multiple clinical sites in Finland and Sweden showed that it could be applied to several relevant patient categories (psychotic, affective, neurotic, organic and alcohol and substance abuse disorders). According to both patients and staff the rating scale promises to become useful both for research and for improvement of routine psychiatric services.

A self-rating version of the UKU Side Effect Rating Scale has been developed. The present study examines the agreement between patients' self-assessment of side effects and the attending clinicians' ratings. The patient sample consisted of 63 patients with schizophrenia under maintenance treatment with risperidone, clozapine or classical antipsychotics. Approximately two thirds of the patients used concomitant medication with e.g. benzodiazepines, SSRIs, anticholinergics. Most inter-correlations between scores for single, corresponding items, subscores of Psychic, Neurological, Autonomic and Other side effects, as well as the Total Score from the patient version of the UKU Side Effect Self Rating Scale (UKU-SERS-Pat) and the clinician version (UKU-SERS-Clin) were found to be statistically significant. Patients reported side effects more frequently and or rated symptoms more severe than the clinicians. The results support the validity of the SERS-Pat and suggest that patient rated side effects may provide important clinical information not detected by clinician rated interviews. Such information can be utilised both in clinical investigations, in development of treatment programs and for individual patients in clinical practice.
