A case of schizophrenia with relapsed catatonia successfully treated with blonanserin transdermal patch.

BACKGROUND: Catatonia is a syndrome that may present with stupor, immobility, and postural retention, and appears in various primary disorders including schizophrenia, depressive disorders, and neurodevelopmental disorders. CASE PRESENTATION: In this report, we describe a 34-year-old female patient with schizophrenia, who had previously been treated with antipsychotic agents to improve psychotic symptoms with delusional symptoms and catatonia. However, she relapsed with catatonic symptoms around 1 year after she voluntarily discontinued the prescribed antipsychotic medications by herself. Her catatonia was successfully improved using the transdermal blonanserin patch, a drug formulation globally first approved in Japan in 2019. DISCUSSION: Although benzodiazepines or electroconvulsive therapy have been recommended as the first-line treatment of catatonic manifestation observed in psychiatric patients, this patient responded well to antipsychotic blonanserin. From the differential drug responses, catatonia may be the complex of heterogeneous conditions with different pathophysiologies.

[Delirium, catatonia and substance withdrawal syndrome manifested as psychomotor agitation in COVID-19: a pharmacological management approach for the general hospital setting]. / Delirium, catatonía y síndrome de abstinencia manifestados como agitación psicomotora en COVID-19: una propuesta de manejo farmacológico en el hospital general.

BACKGROUND: Neuropsychiatric symptoms can be part of the clinical spectrum of COVID-19 infections. AIM: To devise an evidence based clinical algorithm as a guide for clinicians, to identify and treat underlying clinical syndromes of psychomotor agitation, such as delirium, catatonia or substance withdrawal in patients who are hospitalized and infected with SARS-CoV-2. MATERIAL AND METHODS: A review of the literature about the pharmacological management of neuropsychiatric manifestations of COVID-19 at the general hospital, to develop a clinical protocol based on a consensus from an interdisciplinary expert panel at a Clinical Hospital. RESULTS: A consensual clinical algorithm for the management of delirium, catatonia, and substance withdrawal, manifested as psychomotor agitation in patients hospitalized with COVID-19, was developed as a clinical proposal for physicians at different levels of complexity in health services. CONCLUSIONS: Cooperation among different clinical units in the general hospital facilitated the implementation of a clinical algorithm for clinicians for the management of psychomotor agitation in COVID-19 patients.

Treatment of Catatonia with Asenapine in a Patient with Schizotypal Personality Disorder, Psychotic Depression and Septic Shock from SARSCoV- 2 - A Case Report.

INTRODUCTION: Catatonia is a psychomotor syndrome that presents with severe symptoms which can lead to dangerous and lethal conditions if not diagnosed and treated properly. SARS-- CoV-2 is a positive-sense single-stranded RNA virus that can occur in severe cases with acute pneumonia, ARDS, sepsis and septic shock. In these cases, ICU admission is necessary. CASE SUMMARY: A 59-year-old Caucasian man with septic shock and bilateral interstitial pneumonia from SARS-CoV-2 and schizotypal personality disorder presented with catatonic behaviour manifested by soporous state, response to intense painful stimuli with the opening of the eyes, execution of simple verbal commands, maintenance of the same position, catalepsy, immobility, rigidity and mutism. At the same time, there were symptoms of septic shock and catatonic symptoms, causing greater difficulty in the correct formulation of the diagnosis. During the course of his hospitalization, he was treated with asenapine 20 mg/day. The catatonia responded rapidly and significantly to the asenapine. DISCUSSION: To date, the pathophysiology of catatonia is unclear, and few guidelines are available for the treatment of catatonia. In the literature, studies have reported the efficacy of benzodiazepines such as lorazepam and diazepam, GABAA agonists such as zolpidem, NMDA receptor antagonists such as memantine, antidepressant SSRIs such as fluoxetine and paroxetine, and antipsychotics such as olanzapine, clozapine and aripiprazole. We demonstrate that the antipsychotic asenapine is also effective in treating catatonic symptoms in psychiatric disorders. CONCLUSION: Asenapine produced a rapid and significant reduction in catatonic symptoms in our patient with schizotypal personality disorder.
