[Interaction of somatic findings and psychiatric symptoms in COVID-19. A scoping review]. / Interaktion von körperlichen Veränderungen und psychischen Störungen bei COVID-19. Ein Scoping Review.

An infection with SARS-CoV­2 can affect the central nervous system, leading to neurological as well as psychiatric symptoms. In this respect, mechanisms of inflammation seem to be of much greater importance than the virus itself. This paper deals with the possible contributions of organic changes to psychiatric symptomatology and deals especially with delirium, cognitive symptoms, depression, anxiety, posttraumatic stress disorder and psychosis. Processes of neuroinflammation with infection of capillary endothelial cells and activation of microglia and astrocytes releasing high amounts of cytokines seem to be of key importance in all kinds of disturbances. They can lead to damage in grey and white matter, impairment of cerebral metabolism and loss of connectivity. Such neuroimmunological processes have been described as a organic basis for many psychiatric disorders, as affective disorders, psychoses and dementia. As the activation of the glia cells can persist for a long time after the offending agent has been cleared, this can contribute to long term sequalae of the infection.

THE EFFECT OF THE SARS-COV-2 PANDEMIC ON THE INCIDENCE OF PSYCHIATRIC DISORDERS: AN OVERVIEW.

The SARS-CoV-2 pandemic exerted an unprecedented threat to the population worldwide. This led to a sharp increase in symptoms of depression, anxiety, and PTSD, especially in the early phase of the pandemic. As far as data allowed a comparison with the pre-pandemic era, an increase by odds ratios of up to 3,5 was found. People affected by the virus showed an even greater amount of symptomatology as compared to the general population. Next to psychological stress, direct and indirect effects of the virus on the brain in these persons could be observed. Only on very few occasions, a direct invasion of the virus in the brain could be observed. Yet far more important seems to be the induction of a low-grade inflammation in the brain ("neuroinflammation"). This kind of processes have been observed earlier accompanying many psychiatric and neurologic diseases. In this way, especially cognitive symptoms might persist long after the acute infection has abated.

[S1 guidelines for the management of postviral conditions using the example of post-COVID-19]. / Leitlinie S1 für das Management postviraler Zustände am Beispiel Post-COVID-19.

These S1 guidelines are an updated and expanded version of the S1 guidelines on long COVID differential diagnostic and management strategies. They summarize the state of knowledge on postviral conditions like long/post COVID at the time of writing. Due to the dynamic nature of knowledge development, they are intended to be "living guidelines". The focus is on practical applicability at the level of primary care, which is understood to be the appropriate place for initial access and for primary care and treatment. The guidelines provide recommendations on the course of treatment, differential diagnostics of the most common symptoms that can result from infections like with SARS-CoV-2, treatment options, patient management and care, reintegration and rehabilitation. The guidelines have been developed through an interdisciplinary and interprofessional process and provide recommendations on interfaces and possibilities for collaboration.

First-episode psychotic disorders in the wake of the COVID-19 pandemic: a descriptive review of casereports.

OBJECTIVE: Since the onset of COVID-19 pandemic, many case reports and case series dealt with new-onset psychotic disorders in patients either infected with SARS-CoV-2 or thematically linked to the pandemic, but without an infection. Our aim was to provide a comprehensive collection of these reports to illustrate the nature of these psychoses. METHODS: We conducted a literature search in MEDLINE, Embase, PsycINFO, using search terms regarding first-episode psychotic disorders in the context of corona. RESULTS: 96 case reports or case series covering 146 patients (62 without and 84 with SARS-CoV-2 infection) were found. Compared to patients without infection, patients with infection showed significantly more often visual hallucinations (28.6% vs 8.1%), confusion (36.9% vs 11.3%), an acute onset of illness (88.5% vs 59.6%) and less often depression (13.1% vs 35.5%) and a delusional content related to the pandemic (29.5% vs 78.3%). Both groups had an equally favourable outcome with a duration of psychosis ≤2 weeks in half and full remission in two-thirds of patients. In patients with infection, signs of inflammation were reported in 78.3% and increased CRP in 58.6%. While reports on patients with infection are continuously published, no report about patients without infection was found after July 2020. CONCLUSION: Cases without infection were considered reactive and originated all from the first wave of the corona pandemic. In cases with infection, inflammation was considered as the main pathogenetic factor but was not found in all patients. Diagnosis was impeded by the overlap of psychosis with delirium.

[Neuropsychiatric Aspects of COVID-19 - A Narrative Overview]. / Neuropsychiatrische Aspekte von COVID-19 ­ Eine narrative Übersicht.

The SARS-CoV-2 virus (Severe Acute Respiratory Syndrome Coronavirus Type 2) and COVID-19 (Coronavirus Disease 2019) can affect numerous organ systems. In the present paper we offer an overview of the current state of knowledge about the psychiatric aspects of SARS-CoV-2 infection.Medline, Embase und LIVIVO were searched for relevant literature, the last query dating from March 2nd, 2021. Different stress factors in the context of the pandemic can lead to manifest mental illnesses. In addition, there is a risk of neuropsychological changes due to the biological effects of the virus itself.Our work describes the psychological symptoms of COVID-19 sufferers themselves and the psychological effects of the epidemic and the associated socio-economic and psychosocial stress factors on those who are not sick.The most common psychiatric complication among people with COVID-19 is delirium, while hospitalized patients seem to have an increased incidence of symptoms of anxiety, depression and PTSD. There are many case reports on psychotic disorders. In general, an existing psychiatric illness (especially dementia and psychotic disorders) also increases the risk of infection and of a more severe course of the disease. After recovery from COVID-19 infection, there is also a higher incidence of mental illnesses, in particular "Chronic Post-SARS Syndrome" with its manifestations such as fatigue, anxiety, depression and PTSD. In addition, the course of dementia seems to be negatively influenced by an infection with SARS-CoV-2.The second part deals with the effects of the epidemic as a stressor and the established socio-political measures on the mental health of people with and without previous mental illnesses. The literature currently available shows high symptom values for anxiety and depressive disorders as well as post-traumatic stress disorders, stress, suicidality, sleep disorders etc. Risk factors seem to include female gender, younger age and fewer resources, as well as previous psychiatric or physical illnesses. Extrinsic factors such as high infection rates, large numbers of deaths, long curfews/lockdowns, low trust in the government and ineffective measures against economic and social consequences increase the burden.

[Guideline S1: Long COVID: Diagnostics and treatment strategies]. / Leitlinie S1: Long COVID: Differenzialdiagnostik und Behandlungsstrategien.

This guideline comprises the state of science at the time of the editorial deadline. In view of the high turnover of knowledge the guideline is designed as a living guideline. The main objective was to provide a tool for the use in primary care, being considered well suited as a first point of entry and for the provision of care. The guideline gives recommendations on the differential diagnosis of symptoms following SARS-CoV­2 infection, on their therapeutic options, as well as for guidance and care of the patients concerned. It also offers advice concerning return to daily life and rehabilitation. Long COVID being a very variable condition, we chose an interdisciplinary approach.

Serotonin 1A receptor density measured by F18-Mefway PET/CT in mesiotemporal cortex and raphe does not discriminate therapeutic response in patients with major depressive episode.

BACKGROUND: More than 50% of patients with major depressive episode (MDE) fail to respond to initial treatment with first line pharmacological therapy. Altered receptor and serotonin transporter function are considered to be associated with mental disorders. Our investigation aimed on the density of the HT1A receptor in mesiotemporal cortex (MTC) and raphe measured by F18-Mefway in patients with MDD. METHODS: Patients with untreated clinically suspected major depressive episode were recruited from June 2012 to May 2014. 49 patients were included into the study: 36 patients (73%) were identified as responders, whereas 13 (27%) were non-responders. Gender distribution was 26 men (56%) and 23 women (44%). For treatment, only a standard medication of a selective serotonin reuptake inhibitor (SSRI) with escitalopram in a range of 10-20 mg/day was permitted. Responders were defined by improvement of the MADRS>50%. Visually MTC had the highest uptake of F18-Mefway among all brain regions, an asymmetry could not be observed in any patient. An elliptical region was drawn over the amygdala and hippocampus area and a small circular region was drawn over the raphe nuclei. All data were calculated related to (unspecific) cerebellar uptake. RESULTS: The quotient of the right MTC was 5.00 [4.33; 5.50] in all patients, in responders 5.00 [4.00; 5.75] and in non-responders 5.00 [4.50; 5.50] (P=0.56). The quotient of the left MTC presented with a median level of 4.50 [4.50; 5.50] in all persons. The responders had 4.50 [4.50; 5.75] which was not statistically significant to the data of the non-responders with 5.00 [4.50; 5.50] at P=0.64. The raphe had a median quotient of 2.50 [2.00; 3.00] in all and the cohort of responders, whereas non-responders had 2.50 [2.00; 2.50] (P=0.61). Also the absolute values of SUV in the three brain regions were not statistically different between the cohorts. Additionally, we did not find any sex-related differences in our patient group. CONCLUSIONS: Serotonin 1A receptor density can be assessed efficiently by F18-Mefway and PET-CT in patients with MDE. The method can be estimated as a possible tool for clinical and academic investigation, marked tracer uptake can constantly be observed at MTC and the raphe. Anyhow, under conditions of real life in patient care, it is not possible to distinguish patients with a good prognosis who will respond to standard SSRI therapy from non-responders who would benefit from a different therapeutic approach starting earlier.

Amisulpride as an Augmentation Agent in Treatment Resistant Depression: A Case Series and Review of the Literature.

Amisulpride (AMS) in low dosage has been used effectively for treatment of dysthymia. Yet there is a dearth of reports on its use as an augmentation agent in therapy-resistant depression. We deal with this issue presenting case reports and a review of the literature. The addition of 50 mg amisulpride (AMS) to antidepressant therapy in seven patients with depression at different stages of treatment resistance, one of them a case of recurrent brief depression, is described in this report. Augmentation with AMS led to a profound improvement in psychopathology in most patients. The only side effects were elevation of prolactin levels and occasional weight gain. In most cases, improvement occurred early, after only 1-2 weeks of treatment. In some patients, reduction or cessation of AMS led to an immediate and intense recurrence of depressive symptoms that resembled a withdrawal syndrome. Further investigations into the clinical utility and the mode of action of AMS as an augmentation agent are warranted.

Treatment Duration With Long-Acting Injectable Antipsychotics After In-hospital Initiation: A Retrospective Cohort Study.

PURPOSE: Long-acting injectable (LAI) antipsychotics are recommended especially for patients with multiple admissions and poor adherence. The empirical basis of this strategy is a matter of debate. METHODS: In a retrospective cohort study extending over 6 years, all patients admitted for inpatient treatment with a diagnosis of psychotic disorders according to International Statistical Classification of Diseases and Related Health Problems, 10th Revision (F2) were screened for treatment episodes with a new start of an LAI. Indication for LAI treatment was based primarily on previous medication default. All-cause discontinuation was used as a measure of treatment efficiency. Patients with early dropout (termination of LAI treatment within 6 months) were compared with patients with longer treatment (treatment >6 months) for sociodemographic and treatment variables using bivariate and multivariate analyses. RESULTS: A total of 194 treatment episodes with new start of LAIs were identified. Almost one half dropped out within 6 months (early dropout: n = 95 [49%]; mean duration, 2.2 months). Termination of treatment was mainly due to patients' refusal to continue. However, almost a third of patients (61; 31.4%) had a treatment duration of more than 2 years. In a multivariate Cox regression model, longer treatment duration was associated with older age (P = 0.05), not being single (P = 0.04), fewer admissions during the year preceding the index episode (P = 0.02), and better ratings for adherence at the index episode (P = 0.03). CONCLUSIONS: There are both more patients than expected leaving the treatment early and more patients than expected staying for long periods, even among patients with a history of poor adherence.

[Antipsychotic-induced tardive syndromes]. / Antipsychotikainduzierte tardive Syndrome.

Tardive dyskinesia (TD) remains a relevant clinical problem despite the increasing use of new-generation antipsychotics. Antipsychotic-induced tardive syndromes are difficult to treat and have a low tendency of remission. Therefore, prophylaxis is of utmost importance, with the responsible use of antipsychotics as a prime desideratum. With respect to managing tardive dyskinesia, discontinuing the antipsychotic, if possible, albeit not backed up by unequivocal evidence, is still the main recommendation. If this is not possible, the switch to an antipsychotic with a lower TD risk is the next-preferred option. Other symptomatic treatments have been explored, but clinical trials have provided inhomogeneous results and only very few compounds are approved for the treatment of tardive dyskinesia. This manuscript summarizes the current evidence with respect to the phenomenology, course, prevention and treatment of tardive syndromes.

[Heavy users of inpatient services: a comparison of diagnostic subgroups]. / Heavy User stationärer psychiatrischer Behandlung: Vergleich nach Diagnosegruppen.

OBJECTIVE: Quantitative and qualitative assessment of heavy users (HU) of psychiatric inpatient treatment. METHODS: Screening over 9 months for patients with ≥ 3 admissions or ≥ 100 days of treatment during 1 year prior to index admission. RESULTS: During the recruiting period 1217 persons were treated of whom 132 (10.8 %) fulfilled HU criteria. Patients belonged most often to the diagnostic group F2 (43 %), followed by F1 (21 %) and F3 (17 %). HU were most common within the diagnostic group F6 (33 %), next to F2 (21 %), F1 (9 %) and F3 (6 %). HU had signs of more severe illness compared to the other patients: only 8 % held a job and 73 % ware on a disablement pension, patients with a diagnosis of F2 faring worst. HU were treated more frequently involuntarily (50.5 vs 30.7 %). An office-based physician referred only 5 % of the patients and almost half attended the clinic without any referral. HU participated only to a modest degree in community-based treatments and 37 % attended no doctor in the month prior to admission. During the year following the index admission more than 80 % of HU were admitted again and were hospitalized almost as many days as before the index admission. Patients with a diagnosis of F1 and F2 showed the greatest persistence of heavy use behavior. CONCLUSIONS: This sample of HU show a persistent pattern of use of psychiatric inpatient treatment. Strategies to improve the situation are discussed.

[Between faith and delusion]. / Zwischen Glauben und Wahn.

Religious beliefs can lead to difficulties in psychiatric diagnosis, when it comes to distinguishing between faith and delusion. Delusion is defined as a false assessment of reality combined with subjective certainty, which is in contrast with the reality of the social environment. The problem with this definition is that reality cannot be examined with scientific methods/criteria and that the assessment of reality itself underlies historical and cultural fluctuations. The current diagnostic manuals for psychiatric disorders DSM 5 and ICD-10 require, that the content of the belief has to be inadequate even in the subculture of the patient (ICD-10) and that the cultural and socioeconomic background of the patient has to be taken into account (DSM 5). On the basis of this case-report and of selected publications on this topic we want to discuss this diagnostic problem. After that we present a diagnostic model for delusion, which is easy to handle in the daily routine of psychiatrists.

Individual music therapy for mental health care clients with low therapy motivation: multicentre randomised controlled trial.

BACKGROUND: Music therapy (MT) has been shown to be efficacious for mental health care clients with various disorders such as schizophrenia, depression and substance abuse. Referral to MT in clinical practice is often based on other factors than diagnosis. We aimed to examine the effectiveness of resource-oriented MT for mental health care clients with low motivation for other therapies. METHOD: This was a pragmatic parallel trial. In specialised centres in Norway, Austria and Australia, 144 adults with non-organic mental disorders and low therapy motivation were randomised to 3 months of biweekly individual, resource-oriented MT plus treatment as usual (TAU) or TAU alone. TAU was typically intensive (71% were inpatients) and included the best combination of therapies available for each participant, excluding MT. Blinded assessments of the Scale for the Assessment of Negative Symptoms (SANS) and 15 secondary outcomes were collected before randomisation and after 1, 3 and 9 months. Changes were analysed on an intention-to-treat basis using generalised estimating equations in longitudinal linear models, controlling for diagnosis, site and time point. RESULTS: MT was superior to TAU for total negative symptoms (SANS, d = 0.54, p < 0.001) as well as functioning, clinical global impressions, social avoidance through music, and vitality (all p < 0.01). CONCLUSION: Individual MT as conducted in routine practice is an effective addition to usual care for mental health care clients with low motivation.

Mood-dependent changes of serum lithium concentration in a rapid cycling patient maintained on stable doses of lithium carbonate.

OBJECTIVE: Serum lithium levels may be influenced by mood state. We report on a 58-year-old female patient suffering from rapid cycling bipolar disorder. Her serum lithium levels varied greatly, despite stable medication. METHODS: The patient was observed over a one-year period. RESULTS: The patient received a stable medication of lithium carbonate (450 mg), valproate (1500 mg), and clozapine (200 mg). Investigating mood and serum lithium levels over one year revealed six manic and six depressive phases. The mean lithium serum level was 0.67 mmol/L in the depressive states, 0.39 mmol/L in the manic states (t = 4.11, p = 0.001 versus depression), and 0.40 mmol/L in the euthymic states (t = 3.58, p = 0.003 versus depression). Noncompliance was ruled out. The patient gained up to 8 kg during manic phases, accompanied by pretibial edema. CONCLUSIONS: Changes in serum lithium concentration are probably not caused by altered lithium, but by water metabolism. During mania, body water increases, leading to dilution and therefore a reduction in serum lithium levels. As there is no proof for any other known cause of hypervolemia, we propose the hypothesis that the increase in body water is due to a variant of idiopathic edema.

Restless legs syndrome induced by quetiapine: report of seven cases and review of the literature.

We report on seven cases of restless legs syndrome (RLS) in patients treated with quetiapine. Small doses (50-250 mg at bedtime) provoked RLS in a dose-dependent way. Most patients suffered from an affective disorder and all were treated concomitantly with antidepressants. A search of the literature revealed a further nine cases of RLS concerning quetiapine, also afflicting only patients with affective disorders. Quetiapine seems to carry a special risk for RLS in this sort of patient. Possible causes for this concurrence are discussed.

[The diagnosis "schizophrenia": past, present and future]. / Die diagnose: "schizophrenie vergangenheit, gegenwart und zukunft.

Schizophrenia is one of the most important diseases in psychiatry. The diagnostic criteria, first formulated more than 100 years ago, have since undergone multiple changes. While the disease was originally named "dementia praecox" by Emil Kraepelin, the term "schizophrenia" was coined by Eugen Bleuler soon afterwards. DSM-III changed diagnostic criteria dramatically in 1980, relying especially on Kurt Schneider's first rank criteria. These changes were also incorporated into ICD-10. Diagnosis of schizophrenia thus became much more reliable. Yet there remain many problems to be solved: the demarcation towards other psychotic disorders remains arbitrary; the diagnosis is based on multiple, quite different symptoms, enabling two patients being diagnosed with schizophrenia without sharing a single symptom, yet further important symptoms (e.g. cognitive impairments) are not even covered by present diagnostic criteria; until now it was not possible to formulate diagnostic criteria reflecting underlying biological processes or to find a reliable biological marker. These methodological uncertainties are in stark contrast to the persistence of the stigma which accompanies schizophrenia despite all efforts. For the forthcoming publication of DSM-5 and ICD-11 further revisions of diagnostic criteria of schizophrenia are to be expected.

[Risks for Burden among Relatives Caring for Schizophrenia Patients]. / Prädiktoren für die Belastung von Angehörigen Schizophreniekranker.

OBJECTIVE: Relatives of persons with schizophrenia have an essential role in informal caregiving. This may result in a high level of burden. Aim of the study was to investigate, if the frequency of unmet needs among relatives caring for schizophrenia patients increases the risk for burden among these relatives. METHODS: 135 relatives of patients with schizophrenia or schizoaffective disorder were investigated by means of the "Involvement Evaluation Questionnaire" (IEQ) and the "Carer's Needs Assessment for Schizophrenia" (CNA-S). RESULTS: Multiple linear regression analyses showed positive associations between the frequency of caregivers' unmet needs and the IEQ-subscores "tension" and "worrying". Further, the IEQ-subscore "worrying" was significantly lower among caregivers of outpatients than among caregivers of inpatients or day hospital patients. The IEQ-subscore "urging" was significantly associated with patient's negative symptoms. CONCLUSION: Unmet needs among caring relatives have negative effects on their burden. Further, the patients' type of treatment setting (inpatient, outpatient, day hospital) seems to predict caregivers' burden.

Deterioration of metabolic parameters during short-term psychiatric inpatient treatment: a prospective naturalistic study.

OBJECTIVE: To investigate the influence of a single episode of psychiatric inpatient treatment on metabolic parameters. METHODS: A total of 294 consecutive patients of an Upper Austrian psychiatric department were assessed at admission and discharge regarding bodyweight, body mass index (BMI), high density cholesterol (HDL), low density cholesterol (LDL), triglycerides (TG) and fasting glucose (FG), and the TG/HDL ratio. RESULTS: Patients showed an increase of BMI of 0.35 kg/m² (+ 1.3%) during a mean duration of inpatient stay of 25.8 days. LDL rose by 10.7 mg/dl (+ 8.1%), triglycerides by 23.0 mg/dl (+ 17%), HDL decreased by 4.4 mg/dl (-7.4%). Fasting glucose decreased by 3.6 mg/dl (-3.8%), yet the TG/HDL ratio, as a marker for insulin resistance, increased significantly from 2.86 to 3.58 (+ 25.2%) on average. Patients with psychotic disorders gained about three times more weight than patients with other diagnoses. Negative alterations of serum lipids were to be found in all diagnostic groups but were especially pronounced in patients with psychotic disorders who were treated with second-generation antipsychotics clozapine, olanzapine and quetiapine. CONCLUSIONS: Psychiatric inpatient treatment leads to clinically relevant deterioration of metabolic parameters within a short time, most pronouncedly in patients with psychotic disorders.
