ABSTRACT
BACKGROUND: In several randomized controlled trials (RCT) acetylcholinesterase-inhibitors (AChE-I) were tested in patients with mild cognitive impairment (MCI) but were ineffective in delaying disease progression as determined by neuropsychological testing only. Here we present data from an open label observational extension of a multicenter RCT in order to assess if biomarkers are providing useful additional information about a drug's efficacy. We followed 83 amnestic MCI patients and performed correlational analyses of Aß 1-42 and total-Tau in the cerebrospinal fluid (CSF), hippocampal and amygdala volume at baseline, the total duration of blinded and open label AChE-I treatment and the outcome 24 months after inclusion into the RCT. Twelve out of 83 amnestic MCI (14%) had progressed to Alzheimer's disease (AD). Overall, worsening and disease progression as measured by the Alzheimer's Disease Assessment Scale - cognitive subscale (ADAS-cog), Alzheimer's Disease Cooperative Study - Activities of Daily Living (ADCS-ADL) and Clinical Dementia Rating (CDR) did not correlate with the duration of AChE-I treatment. However, a specific multidimensional biomarker profile at baseline indicated more reliably than cognitive testing alone progression to AD. We conclude that pharmacological RCTs testing symptomatic treatment effects in MCI should include biomarker assessment.

Approximately 1.2 million refugees have arrived in Germany since autumn 2014. They are often appraised as being a challenge for the German healthcare system because the acute need for healthcare support was large and appeared suddenly while at the same time resources were limited. This situation was previously unknown for a western European healthcare system, whereas it constitutes a typical challenge for nongovernmental organizations that are active in the field of emergency relief and development aid and that have developed a large number of successful intervention concepts. Of central importance in this context are the basic principles of equal rights, participation of those affected, the principle of nonmaleficence, the resource orientation instead of a deficit orientation as well as the need for integrated and stepped care models. These can serve as general principles not only in the setting of development aid in crisis areas worldwide but also in the health services provided to refugees in the current situation in Germany.

OBJECTIVES: Minocycline is a tetracycline antibiotic increasingly recognized in psychiatry for its pleiotropic anti-inflammatory and neuroprotective potential. While underlying mechanisms are still incompletely understood, several lines of evidence suggest a relevant functional overlap with retinoic acid (RA), a highly potent small molecule exhibiting a great variety of anti-inflammatory and neuroprotective properties in the adult central nervous system (CNS). RA homeostasis in the adult CNS is tightly controlled through local RA synthesis and cytochrome P450 (CYP450)-mediated inactivation of RA. Here, we hypothesized that minocycline may directly affect RA homeostasis in the CNS via altering local RA degradation. METHODS: We used in vitro RA metabolism assays with metabolically competent synaptosomal preparations from murine brain and human SH-SY5Y neuronal cells as well as viable human SH-SY5Y neuroblastoma cell cultures. RESULTS: We revealed that minocycline potently blocks RA degradation as measured by reversed-phase high-performance liquid chromatography and in a viable RA reporter cell line, even at low micromolar levels of minocycline. CONCLUSIONS: Our findings provide evidence for enhanced RA signalling to be involved in minocycline's pleiotropic mode of action in the CNS. This novel mode of action of minocycline may help in developing more specific and effective strategies in the treatment of neuroinflammatory or neurodegenerative disorders.

BACKGROUND: Aim was to examine depressive symptoms in acutely ill schizophrenia patients on a single symptom basis and to evaluate their relationship with positive, negative and general psychopathological symptoms. METHODS: Two hundred and seventy-eight patients suffering from a schizophrenia spectrum disorder were analysed within a naturalistic study by the German Research Network on Schizophrenia. Using the Calgary Depression Scale for Schizophrenia (CDSS) depressive symptoms were examined and the Positive and Negative Syndrome Scale (PANSS) was applied to assess positive, negative and general symptoms. Correlation and factor analyses were calculated to detect the underlying structure and relationship of the patient's symptoms. RESULTS: The most prevalent depressive symptoms identified were depressed mood (80%), observed depression (62%) and hopelessness (54%). Thirty-nine percent of the patients suffered from depressive symptoms when applying the recommended cut-off of a CDSS total score of >6 points at admission. Negligible correlations were found between depressive and positive symptoms as well as most PANSS negative and global symptoms despite items on depression, guilt and social withdrawal. The factor analysis revealed that the factor loading with the PANSS negative items accounted for most of the data variance followed by a factor with positive symptoms and three depression-associated factors. LIMITATIONS: The naturalistic study design does not allow a sufficient control of study results for the effect of different pharmacological treatments possibly influencing the appearance of depressive symptoms. CONCLUSION: Results suggest that depressive symptoms measured with the CDSS are a discrete symptom domain with only partial overlap with positive or negative symptoms.

OBJECTIVE: To evaluate the predictive validity of early response in first-episode schizophrenia within a 1-year follow-up trial and to compare the resulting cutoff to the currently proposed early response definition (20% improvement by week 2). METHOD: Receiver operator characteristic (ROC) analyses were used to identify the predictive validity of the psychopathological improvement of treatment from week 1 to week 8, regarding the maintenance of response until week 52 as well as to define the most reasonable cutoff in 132 first-episode patients. The Youden Index (maximum of sensitivity and specificity) was used to compare the newly developed and the commonly used early response definition. RESULTS: Starting with week 6, a reasonable validity to predict the maintenance of response was found (area under the curve = 0.721) with the best fitting cutoff being a 51.6% PANSS total score improvement. Using this cutoff 74 patients (56%) were correctly identified to become responder and maintain response during follow-up (sensitivity: 0.747). The Youden Index was higher applying the newly developed early response cutoff featuring higher specificity compared to the commonly used early response definition. CONCLUSION: Regarding long-term treatment, it seems more appropriate to base predictions of the patient's maintenance of response not before 6 weeks of treatment.

BACKGROUND: Early diagnosis of Alzheimer's disease (AD) may be corroborated by imaging of beta-amyloid plaques using positron emission tomography (PET). Here, we performed an add-on questionnaire study to evaluate the relevance of florbetaben imaging (BAY 949172) in diagnosis and consecutive management of probable AD patients. METHODS: AD patients with a clinical diagnosis in accordance with the NINCDS-ADRDA criteria or controls were imaged using florbetaben. Referring physicians were asked on a voluntary basis about their confidence in initial diagnosis, significance of PET imaging results, and their anticipated consequences for future patient care. RESULTS: 121 questionnaires for probable AD patients and 80 questionnaires for controls were evaluated. In 18% of patients who had initially received the diagnosis of probable AD, PET scans were rated negative, whereas in controls 18% of scans were positive. An increase in confidence in the initial diagnosis was frequently reported (80%). Imaging results had a significant impact on the intended patient care, as judged by the referring physicians; this was most prominent in those patients with a contradicting scan and/or a low confidence in the initial diagnosis. CONCLUSION: Florbetaben amyloid imaging increases the overall confidence in diagnosis of AD and may frequently influence clinical decisions and patient management.

OBJECTIVES: Mild cognitive impairment (MCI) is etiologically heterogeneous, and a substantial proportion of MCI subjects will develop different dementia disorders. One subtype of this syndrome, amnestic MCI, occurs preferentially but not exclusively in prodromal AD and is characterized by defined deficits of episodic memory. DESIGN, SETTING AND PARTICIPANTS: For a 2-year, double-blinded, placebo-controlled study MCI patients, presenting with an amnestic syndrome but not necessarily based on presumed prodromal AD were randomized. INTERVENTION: Patients received (a) a combination of 16 mg galantamine plus 20 mg memantine, or (b) 16 mg galantamine alone or (c) placebo. MEASUREMENTS: The primary objective was to explore the differential impact of these interventions on the progression to dementia and on cognitive changes as measured by the ADAScog. RESULTS: After recruitment of 232 subjects, the trial was halted before reaching the planned sample size, because safety concerns arose in other studies with galantamine in MCI. This resulted in a variable treatment duration of 2-52 weeks. The statistical analysis plan was amended for studying cognitive effects of discontinuing the study medication, which was done separately for galantamine and memantine, and under double-blind conditions. There was one death, no unexpected severe adverse events, and no differences of severe adverse events between the treatment arms. The cognitive changes on the ADAScog were not different among the groups. Only for the subgroup of amnestic MCI with presumed AD etiology, a significant improvement of ADAScog score over placebo before the discontinuation of medication was observed, while amnestic MCI presumably due to other etiologies showed no cognitive changes with broad variation. Cognitive improvement was numerically larger in the combination treatment group than under galantamine alone. Patients who received placebo declined as expected. Discontinuation of galantamine, either as part of the combination regimen or as mono treatment, resulted in a transient decline of the ADAScog score in amnestic MCI of presumed AD etiology, while discontinuation of Memantine did not change the cognitive status. CONCLUSION: In an interrupted trial with amnestic MCI subjects the combination of galantamine plus memantine were generally well tolerated. In the subgroup of MCI subjects with presumed AD etiology, a cognitive benefit of a short-term combination treatment of galantamine plus memantine was observed, and cognitive decline occurred after discontinuation of galantamine.

BACKGROUND: To analyse insight of illness during the course of inpatient treatment, and to identify influencing factors and predictors of insight. METHODS: Insight into illness was examined in 399 patients using the item G12 of the Positive and Negative Syndrome Scale ("lack of insight and judgement"). Ratings of the PANSS, HAMD, UKU, GAF, SOFAS, SWN-K and Kemp's compliance scale were performed and examined regarding their potential association with insight. The item G12 was kept as an ordinal variable to compare insight between subgroups of patients. RESULTS: Almost 70% of patients had deficits in their insight into illness at admission. A significant improvement of impairments of insight during the treatment (p<0.0001) was observed. At admission more severe positive and negative symptoms, worse functioning and worse adherence were significantly associated with poorer insight. Less depressive symptoms (p=0.0004), less suicidality (p=0.0218), suffering from multiple illness-episodes (p<0.0001) and worse adherence (p=0.0012) at admission were identified to be significant predictors of poor insight at discharge. CONCLUSION: The revealed predictors might function as treatment targets in order to improve insight and with it outcome of schizophrenia.

BACKGROUND: Self-ratings of psychotic experiences might be biased by depressive symptoms. METHOD: Data from a large naturalistic multicentre trial on depressed inpatients (n=488) who were assessed on a biweekly basis until discharge were analyzed. Self-rated psychotic symptoms as assessed with the 90-Item Symptom Checklist (SCL-90) were correlated with the SCL-90 total score, the SCL-90 depression score, the Beck Depression Inventory (BDI), the Hamilton Depression Rating Scale 21 item (HAMD-21) total score, the Montgomery Åsberg Depression Rating Scale (MADRS) total score and the clinician-rated paranoid-hallucinatory score of the Association for Methodology and Documentation in Psychiatry (AMDP) scale. RESULTS: At discharge the SCL-90 psychosis score correlated highest with the SCL-90 depression score (0.78, P<0.001) and with the BDI total score (0.64, P<0.001). Moderate correlations were found for the MADRS (0.34, P<0.001), HAMD (0.37, P<0.001) and AMDP depression score (0.33, P<0.001). Only a weak correlation was found between the SCL-90 psychosis score and the AMDP paranoid-hallucinatory syndrome score (0.15, P<0.001). Linear regression showed that change in self-rated psychotic symptoms over the treatment course was best explained by a change in the SCL-90 depression score (P<0.001). The change in clinician-rated AMDP paranoid-hallucinatory score had lesser influence (P=0.02). CONCLUSIONS: In depressed patients self-rated psychotic symptoms correlate poorly with clinician-rated psychotic symptoms. Caution is warranted when interpreting results from epidemiological surveys using self-rated psychotic symptom questionnaires as indicators of psychotic symptoms. Depressive symptoms which are highly prevalent in the general population might influence such self-ratings.

Parkinson's disease (PD) is frequently compounded by neuropsychiatric complications, increasing disability. The combined effect of motor and mental status on care-dependency in PD outpatients is not well characterized. We conducted a cross-sectional study of 1449 PD outpatients. The assessment comprised the Montgomery-Asberg Depression Rating Scale (MADRS) and the diagnostic criteria for dementia. PD severity and treatment complications were rated using Hoehn and Yahr staging and the Unified Parkinson's Disease Rating Scale (UPDRS) IV. The acknowledged level of care-dependency was documented. Care-dependency was present in 18.3% of all patients. A total of 13.9% had dementia, 18.8% had depression, and 14.3% had both. Regression analyses revealed increasing effects of age, PD duration, and PD severity on care-dependency in all three mental-disorder subgroups with the strongest effects in patients with depression only. Depressed patients with antidepressive treatment still had significantly higher PD severity, higher MADRS and UPDRS-IV scores but were not more likely to be care-dependent than non-depressed patients. Older age, longer duration and increased severity of PD contribute to care-dependency in patients with untreated depression. Treatment of depression is associated with lower rates of care-dependency.

BACKGROUND: Parkinson's disease (PD) is frequently accompanied by dementia or depression which can aggravate the clinical picture of the disease and increase the risk of care dependency (CD). Little is known about the associations between PD, these neuropsychiatric comorbidities and CD in outpatients. PATIENTS AND METHODS: A nationwide sample of outpatients (n=1,449) was examined by office-based neurologists (n=315) comprising the documentation of the general, neurological status and the degree of CD. The dementia status was clinically rated according to the established DSM-IV criteria. Depression was screened with the Montgomery-Asberg Depression Rating Scale (MADRS). RESULTS: Overall, 18.3% of all patients were care dependent. Even after adjustment for PD severity, patients with depression (OR=2.8; 95% CI 1.8-4.3), dementia (OR=2.7; 95% CI 1.8-4.1) or both (OR=3.9; 95% CI 2.5-60,0) were at higher risk for CD than patients without dementia or depression. Patients aged ≥76 years were fourfold more likely to be care dependent than patients aged ≤65 years (OR=3.5; 95% CI 2.3-5.5). Across all age groups, patients with depression featured the highest increments (from 11.9 to 42.0%). CONCLUSION: The risk for CD is substantially elevated in outpatients with PD when further neuropsychiatric symptoms are present. The data suggest that depression contributes equally to disability as does dementia.

BACKGROUND: The clinical diagnosis of Alzheimer's disease in early stages may be substantiated by the quantification of the biomarkers Abeta42, Abeta40 and total-Tau (t-Tau) in cerebrospinal fluid (CSF). Different commercially available immunosorbent assays yield reliable results, yet the absolute values obtained may differ in between tests. METHODS: We used CSF samples from patients that reported to our memory clinic. Enzyme-linked immunosorbent assays obtained from Innogenetics were used for the quantification of Abeta42 and t-Tau, test kits from IBL International were used to determine Abeta42 and Abeta40 concentrations. The multiplex assay system obtained from Mesoscale Discovery (MSD) Systems was used for the quantification of all three biomarkers. RESULTS: For all biomarkers, the absolute values obtained with different test systems differ. However, the data sets highly correlate for all comparisons, with the MSD test system proving to be slightly more sensitive. Correlation coefficients (c) for the Abeta42 and Abeta40 quantifications lie between c = 0.80 and c = 0.87, and for the t-Tau quantifications we determined c = 0.99. CONCLUSION: We conclude that all assays evaluated give reliable results, yet absolute values obtained have to be assessed differently within the framework of diagnostic procedures, depending on the system used.

INTRODUCTION: Assessment of depression severity is of key importance, since several clinical guidelines recommend choice of treatment dependent on the depression severity grade. Using different tools to assess baseline severity may result in different outcomes. METHODS: This paper describes the results of a multicentre, naturalistic study investigating the relationship between depression symptom severity (using 4 different measures of symptom severity) and clinical outcome among patients hospitalised for depression (N=1 014). Moreover, the impact of differences between methods of measuring depression severity has been investigated. Statistical analyses (univariate measurements, logistic regression models) were conducted to detect coherences and differences between the various methods of severity categorisation. RESULTS: Results revealed different associations between outcome and classification methods. Response or remission rates varied if baseline severity was assessed by different instruments. Moreover, the number of responders increased with higher baseline severity grades of depression, whereas the number of remitters decreased. Additional analyses dependent on outcome criteria using continuous instead of categorical data revealed similar results. DISCUSSION: Baseline severity may be only one of many other important clinical variables that mediate clinical outcome, but it is surely an important one deserving further research and consideration.

OBJECTIVE: To examine depressive symptoms, their course during treatment, and influence on outcome. METHOD: Weekly Calgary Depression Scale for Schizophrenia ratings were performed in 249 inpatients with schizophrenia. Early response was defined as a 20% reduction in the total score of the Positive and Negative Syndrome Scale for Schizophrenia from admission to week 2, response as a 50% reduction in the total score of the Positive and Negative Syndrome Scale for Schizophrenia (PANSS) from admission to discharge and remission according to the consensus criteria. RESULTS: Thirty six per cent of the patients were depressed at admission, with 23% of them still being depressed at discharge. Depressed patients scored significantly higher on the PANSS negative and general psychopathology subscore, featured more impairments in subjective well-being (P < 0.0001) and functioning (P < 0.0001). They suffered from more suicidality (P = 0.0021), and had greater insight into their illness (P = 0.0105). No significant differences were found regarding early response, response, and remission. CONCLUSION: Patients with depressive symptoms should be monitored closely, given the burden of negative symptoms, their impairments in well-being and functioning and the threat of suicidality.

BACKGROUND: Purpose of this study was to assess subjective well-being in schizophrenia inpatients and to find variables predictive for response and remission of subjective well-being. METHOD: The subjective well-being under neuroleptic treatment scale (SWN-K) was used in 232 schizophrenia patients within a naturalistic multicenter trial. Early response was defined as a SWN-K total score improvement of 20% and by at least 10 points within the first 2 treatment weeks, response as an improvement in SWN-K total score of at least 20% and by at least 10 points from admission to discharge and remission in subjective well-being as a total score of more or equal to 80 points at discharge. Logistic regression and CART analyses were used to determine valid predictors of subjective well-being outcome. RESULTS: Twenty-nine percent of the patients were detected to be SWN-K early responders, 40% fulfilled criteria for response in subjective well-being and 66% fulfilled criteria for remission concerning subjective well-being. Among the investigated predictors, SWN-K early improvement and the educational status were significantly associated with SWN-K response. The SWN-K total score at baseline showed a significant negative predictive value for response. Baseline SWN-K total score, PANSS global subscore, and side effects as well as the educational status were found to be significantly predictive for remission. CONCLUSIONS: Depressive symptoms should be radically treated and side effects closely monitored to improve the patient's subjective well-being. The important influence of subjective well-being on overall treatment outcome could be underlined.

Posttraumatic stress disorder (PTSD) is a severe, frequently chronic condition with a high rate of co-morbidity with other psychiatric syndromes. In contrast to the majority of psychiatric disorders, the traumatic event in PTSD constitutes a clearly defined etiological factor. A growing understanding of the mechanisms contributing to the development of PTSD has highlighted the possibilities for early preventive psychological and pharmacological treatment during the so-called golden hours after a traumatic experience. Whereas preliminary evidence suggests that a pharmacological recalibration of the HPA system and cognitive behavioral therapy may be helpful, other frequently used strategies, such as psychological debriefing or benzodiazepine treatment, seem to be largely ineffective, possibly even worsening PTSD symptoms.

BACKGROUND: The aim of this paper is to apply the proposed consensus remission criteria to an acutely ill inpatient sample at admission and evaluate their adaptability in this patient population and pharmaceutical trials. METHODS: The Remission in Schizophrenia Working Group's consensus criteria were applied to 272 acutely ill schizophrenia patients. Patients were examined using the PANSS, HAMD, UKU and SWN-K total scales at admission as well as the GAF, SOFAS and the Strauss-Carpenter Prognostic Scale. Sociodemographic and clinical baseline variables were assessed using a standardized documentation system. RESULTS: 33 patients (12%) fulfilled the symptom severity component of the proposed remission criteria already at baseline. Almost no significant differences were found when comparing patients with achieved and failed symptom severity component that would explain the hospitalization of the patients with achieved criteria despite their apparently mild psychopathological symptoms. The only explainable difference was that patients with an achieved symptom severity component had received significantly more antipsychotics and had suffered from significantly more life events before admission. CONCLUSION: The present results raise the question whether the symptom severity threshold is adequate to identify patients in remission when applied in clinical trials.

UNLABELLED: It is unknown, how frequently Parkinson's disease (PD) is complicated by dementia, depression and other neuropsychiatric conditions. An epidemiologic characterisation of the situation in specialised neurologic settings is lacking. The Geman Study on the Epidemiology of Parkinson's Disease with Dementia (GEPAD) isa national representative epidemiological study of n=1449 PD patients in n=315 office-based neurological settings, designed to estimate the prevalence of dementia, depression and other neuropsychiatric conditions in patients with PD of all stages by using standardized clinical assessments. RESULTS: 28.6% met DSM-IV criteria for dementia. 33.6% met criteria for depression and 61% additionally had other clinically significant psychopathological syndromes. Only 29.4% had no neuropsychiatric conditions. GEPAD reveals for the first time comprehensively that the neuropsychiatric burden of PD patients in all stages and even early stages is considerable, posing challenging questions for research and clinical management.

OBJECTIVE: To describe the course of positive and negative symptoms during inpatient treatment and examine remission and response rates under routine clinical care conditions. METHODS: Two hundred and eighty inpatients with schizophrenia (DSM-IV criteria) were assessed with the Positive and Negative Syndrome Scale (PANSS) at admission and at biweekly intervals until discharge from hospital. Remission was defined according to the symptom-severity component of the consensus criteria (Remission in Schizophrenia Working Group) as a rating of three or less in the relevant PANSS items at discharge, and response as a reduction of at least 20% in the PANSS total score from admission to discharge. RESULTS: The mean duration of inpatient treatment was 54.8 days. Of the total sample, 78.5% achieved the criteria for response and 44.6% those for remission. Mean PANSS total scores decreased from 72.4 at admission to 52.5 at discharge (p<0.001). A reduction in PANSS total scores was found from visit to visit, up to week 8. The most pronounced decline was observed within the first two weeks of treatment. CONCLUSION: Response rates were comparable to those found in efficacy studies, and remission rates were slightly higher. This may be explained by differences in the selection and the treatment of patients. Nevertheless, the findings might indicate that a complex naturalistic treatment approach is beneficial in terms of effectiveness.
