Purpose: To develop and evaluate a self- and observer-rating scale on quality of life in patients suffering from schizophrenia with regard to the efficacy of atypical antipsychotics based on different dimensions and to apply within a pilot study.Methods: Following review of existing scales and a prevalidation phase, the Riedel-Spellmann-Musil (RSM) scale was developed comprising 36 items assigned to different subscales. As reference scales, the Quality of Life Scale (QLS) and the Subjective Well-being Under Neuroleptic Treatment Scale-short version (SWN-K) were performed, psychopathology and adverse events were measured at all visits. Reliability was assessed using Cronbach's alpha, Pearson's correlation coefficients were used to assess construct validity, and Intraclass Correlation Coefficients (ICCs) were used for test-retest reliability. T tests were performed in normal distributed samples; otherwise Wilcoxon tests were used.Results: One hundred and thirty-six patients were included in the study. Cronbach`s α was 0.917 for the self-rating and 0.915 for the interviewer-rating part. ICCs were >0.70 for all subscales. The self-rating part correlated strongly with the SWN-K and the observer part with the QLS. Changes in psychopathology over the study period and different levels of functioning were detected.Conclusion: The RSM-scale is a new scale to assess the quality of life in different dimensions of patients with schizophrenia treated with antipsychotics and shows good internal consistency, test-retest reliability, construct and discriminant validity.

Working memory as a part of higher-order executive functions is defined by the parallel storage and processing of information. Recent functional fMRI studies have revealed a functional, interregional disintegration of a neuronal network connecting cortical, subcortical and cerebellar regions in schizophrenic patients (SZ). Cognitive impairment in working memory is a core psychopathological correlate of schizophrenic symptoms. Atypical neuroleptics such as quetiapine have shown good efficacy in treating positive and negative symptoms. The presented study evaluated the impact of a neuroleptic steady state treatment with quetiapine on the altered working memory activation patterns in schizophrenia. Patients were examined by fMRI at baseline and after 12 weeks of steady state treatment with quetiapine. Matched healthy controls (HC) underwent baseline examination. In the scanner, stimuli were presented in a 2-back and 0-back condition of a working memory (wm) paradigm, whereby a degraded and a non-degraded version were used each time. Additionally, behavioural responses (reaction time to target stimuli and error ratio) were measured. At baseline, healthy controls revealed increased activity in the frontal lobe, especially in regions of the prefrontal cortex. Compared to HC, SZ showed hypoactivation in the right dorsolateral prefrontal cortex (DLPFC) and the ventrolateral prefrontal cortex (VLPFC) bilaterally for the 2-back condition. In the 2-back degraded condition there was a hypoactivation in both, the right DLPFC and the VLPFC. Additionally, patients showed bilaterally decreased activation in the basalganglia in the 2-back and in the right caudatus in the 2-back degraded condition compared to healthy controls. After treatment with quetiapine, patients activations patterns were increased. The pre–post comparison of the 2-back condition revealed a significant increase of activation in the left VLPFC at a significance level of 0.001 (uncorrected). The 2-back degraded condition led to a significant activation pattern in the lingual gyrus and the right precuneus. In both wm conditions, at baseline there were no differences in reaction time but only a worse performance in SZ. After treatment, behavioural measurement of responses, including reaction time and performance, showed slight improvements in SZ, although these did not reach statistical significance. The neuronal networks underlying working memory are clearly altered in schizophrenia. After 12 weeks of treatment with quetiapine monotherapy, patients showed significant clinical improvement and revealed increased BOLD activity in the VLPFC during a working memory task, although there was no improvement of cognitive performance.

Signs of an inflammatory process, in particular increased pro-inflammatory cytokines and increased levels of prostaglandine E
2 (PGE2 ), have repeatedly been described in major depression (MD). As cyclooxygenase-2 (COX-2) inhibitors inhibit the PGE2 production and the production of pro-inflammatory cytokines, we performed a therapeutic trial with the COX-2 inhibitor celecoxib. In a prospective, double-blind, add-on study, 40 patients suffering from an acute depressive episode were randomly assigned to either reboxetine and celecoxib or to reboxetine plus placebo. After a wash-out period, 20 patients received 4–10 mg reboxetine plus placebo and 20 received reboxetine plus 400 mg celecoxib for 6 weeks. The treatment effect was calculated by analysis of variance. There were no significant differences between groups in age, sex, duration or severity of disease or psychopathology, or reboxetine dose or plasma levels. Over 6 weeks, both groups of patients showed significant improvement in scores of the Hamilton Depression Scale. However, the celecoxib group showed significantly greater improvement compared to the reboxetine-alone group. Additional treatment with celecoxib has significant positive effects on the therapeutic action of reboxetine with regard to depressive symptomatology. Moreover, the fact that treatment with an anti-inflammatory drug showed beneficial effects on MD indicates that inflammation is related to the pathomechanism of the disorder, although the exact mechanisms remain to become elucidated.Molecular Psychiatry (2006) 11, 680–684. doi:10.1038/sj.mp.4001805; published online 21 February 2006 [ABSTRACT FROM AUTHOR]- Published
