First-Time Psychotic Symptoms in a Patient After COVID-19 Infection-A Case Report

Successful ECT in an adolescent with catatonia and psychosis due to COVID-19

This case report highlights the use of ECT in an adolescent patient with a COVID-19 infection, which is an area of limited data. The patient received a full course of bitemporal ECT, with a total of 15 treatments administered over four months. The patient responded robustly, with a complete return to her pre-infection baseline mental status, and response has remained durable for one-year post continuation phase ECT taper. Maintenance ECT considerations for catatonia should be determined on a case-by-case basis but was not needed for our patient, given the durability of the response to ECT.

COVID-19-Associated Acute Psychotic Disorder-Longitudinal Case Report and Brief Review of Literature

Even though since the beginning of the COVID-19 pandemic, the literature became more and more abundant on data and hypotheses about the various consequences on people's lives, more clarity needs to be added to the existing information. Besides the stressful experiences related to the COVID-19 pandemic, SARS-CoV-2 infection has been proven to impact brain functioning through direct and indirect pathogenic mechanisms. In this context, we report a case of a patient presenting with a first episode of psychosis following COVID-19. In our case, a 28-year-old male patient with no personal or family psychiatric history developed psychotic symptoms (delusions, hallucinations, and disorganized behaviour) that required antipsychotic treatment and inpatient hospitalization one week after he was discharged from the hospital after COVID-19. At the six-month and one-year follow-up, the patient was in remission without any psychotic signs or symptoms. A brief review of the literature is also provided. The case presented in this article outlines the possibility that the post-COVD-19 recovery period might be a crucial time for the onset of acute psychotic disorder, and therefore, routine psychiatric assessments should be carried out during all phases of the disease. A clearer picture of the impact of the COVID-19 pandemic on mental health will most likely be revealed in the future as many consequences need long-term evaluation.

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.

Pharmacological Treatment of Acute Psychiatric Symptoms in COVID-19 Patients: A Systematic Review and a Case Series

Delirium and psychomotor agitation are relevant clinical conditions that may develop during COVID-19 infection, especially in intensive care unit (ICU) settings. The psychopharmacological management of these conditions is receiving increasing interest in psychiatry, considering hyperkinetic delirium as one of the most common neuropsychiatries acute consequences in COVID-19 recovery patients. However, there are no actual internationally validated guidelines about this topic, due to the relatively newly introduced clinical condition; in addition, a standardized psychopharmacologic treatment of these cases is a complex goal to achieve due to the risk of both drug-drug interactions and the vulnerable conditions of those patients. The aim of this systematic review and case series is to evaluate and gather the scientific evidence on pharmacologic handling during delirium in COVID-19 patients to provide practical recommendations on the optimal management of psychotropic medication in these kinds of patients. The electronic databases PubMed, Embase and Web of Science were reviewed to identify studies, in accordance with the PRISMA guidelines. At the end of the selection process, a total of 21 studies (n = 2063) were included. We also collected a case series of acute psychomotor agitation in COVID-19 patients hospitalized in ICU. Our results showed how the symptom-based choice of the psychotropic medication is crucial, and even most of the psychotropic drug classes showed good safety, one must not underestimate the possible drug interactions and also the possible decrease in vital functions which need to be strictly monitored especially during treatment with some kinds of molecules. We believe that the evidence-based recommendations highlighted in the present research will enhance the current knowledge and could provide better management of these patients.

The Impact of the COVID-19 Virus Pandemic on the Incidence of First Psychotic Spectrum Disorders

The effects of COVID-19 on the human body are not yet understood enough. Medical history provides information on cases of psychiatric symptoms during viral infections in the 20th century, such as the influenza pandemic. Currently, it is observed that there is an increasing number of new psychiatric disorders in previously healthy individuals. In addition, because of the decreased amount of reporting to health care providers, including psychiatrists, many physicians suggest that the number of neuropsychiatric disorders may be underestimated. In this paper, we review available studies on the occurrence of first-time psychotic spectrum disorder (PSD) in individuals related to SARS-CoV-2 infection. The reviewed studies suggest that first-time psychotic disorder in COVID-19 patients is statistically significantly more frequent compared to influenza, as well as to other respiratory infections. The emergence of new PSDs is explained by direct neurotropism of the virus on the one hand and by immunological mechanisms on the other. The main conclusions of this review should be treated with caution, and future research on this topic is needed. The authors recognize the particular need to develop standardized laboratory panels that include inflammatory markers (IL-6, TNF-α), cerebrospinal fluid (CSF) testing, and SARS-CoV-2 antibody assays to entirely understand the etiology of neuropsychiatric complications of SARS-CoV-2 infections and the pandemic itself. In addition, public health efforts are required to promote mental health, especially during COVID-19.

Syncytin, envelope protein of human endogenous retrovirus (HERV): no longer 'fossil' in human genome

Human endogenous retroviruses (HERVs) are 'fossil viruses' that resulted from stable integrations of exogenous retroviruses throughout evolution. HERVs are defective and do not produce infectious viral particles. However, some HERVs retain a limited coding capacity and produce retroviral transcripts and proteins, which function in human developmental process and various pathologies, including many cancers and neurological diseases. Recently, it has been reported that HERVs are differently expressed in COVID-19 disease caused by infection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In this review, we discuss the molecular structure and function of HERV ENV proteins, particularly syncytins, and their conventional roles in human development and diseases, and potential involvement in COVID-19 regarding the newly reported mental symptoms. We also address COVID-19 vaccine-related infertility concerns arising from the similarity of syncytin with the spike protein of SARS-CoV-2, which have been proved invalid.
