RESUMO

Neuroleptic malignant syndrome (NMS) is a severe adverse reaction associated with neuroleptic or antipsychotic drugs. This case report discusses a 43-year-old man with a history of bipolar disorder and polysubstance abuse who presented with altered mental status, autonomic dysfunction, and muscular rigidity. The patient had recently started on ziprasidone, a second-generation antipsychotic, leading to an atypical presentation of NMS. Unlike classic findings associated with NMS induced by first-generation antipsychotics, this case lacked high fever, lead pipe rigidity, or elevated creatine kinase levels greater than 1000 on initial presentation. The delay in diagnosis was attributed to the milder symptoms and absence of typical findings, resulting in extensive diagnostic workup and interventions. The patient responded positively to treatment with lorazepam based on the Woodbury severity stage guidelines. This case underscores the complexity of diagnosing NMS induced by second-generation antipsychotics and highlights the need for awareness and tailored treatment approaches for atypical presentations.

RESUMO

Malignant catatonia (MC) is a complex, life-threatening condition characterized by motor dysregulation and autonomic instability, which requires prompt and effective treatment. There are some limitations to the current recommendations for treating MC, including barriers to receiving ECT, failure to respond to benzodiazepines, or benzodiazepine intolerance. To the authors' knowledge, there are 3 case reports in the literature describing the use of amantadine in the treatment of MC. We present the case of a 51-year-old female with a history of multiple medical and psychiatric conditions who was admitted to the hospital for altered mental status. During her admission, she developed symptoms that raised concern about MC, which was initially managed with lorazepam. However, due to concerns about severe respiratory compromise, lorazepam was discontinued, and the patient was started on liquid amantadine. She showed marked reduction in the symptoms of malignant catatonia, and the autonomic instability resolved after she was started on amantadine. The patient was eventually discharged home with outpatient follow-up scheduled. Our case report shows successful treatment of MC with liquid amantadine in a patient who was unable to tolerate escalating doses of benzodiazepines. The positive response to amantadine suggests that it may be a useful treatment option for MC. While further studies are needed, clinicians should consider the use of amantadine in the treatment of MC, especially in patients who are unable to tolerate benzodiazepines, who have failed to respond to treatment with benzodiazepines, or who are being treated in institutions where the availability of ECT is limited. Amantadine may be more readily accessible given its multiple formulations and wide availability.

RESUMO

Symptoms of catatonia include silence, motionlessness, and postural retention. Although it is important to detect and treat catatonia early, before it becomes severe, postoperative cases have inherent risks that hinder diagnosis and treatment. A 60-year-old man with schizophrenia underwent endoscopic/thoracoscopic esophagectomy and was extubated in the operating room. In the intensive care unit (ICU), he had stiffness in the neck, ankles, and knees, catalepsy during passive knee flexion, mild disturbance of consciousness, mild creatine kinase elevation, and respiratory depression. Intravenous diazepam was administered for diagnosis, and the patient's rapid improvement indicated catatonia. He was intubated and started on lorazepam; tapering produced no recurrence of symptoms. The patient was extubated and transferred to the general ward on postoperative Day 2. Because this patient was extubated in the operating room and was managed postoperatively in the ICU with a full-time doctor, his symptoms were easily recognized and early diagnosis was possible. Thus, we were able to administer drug therapy quickly and adequately and perform forward management that accounted for postoperative risks, thereby achieving a favorable outcome.

RESUMO

Catatonia is a neuropsychiatric disorder characterized by motor, affective and cognitive-behavioural signs, which lasts from hours to days. Intensive research over the past two decades has led to catatonia being recognized as an independent diagnosis in the International Classification of Diseases, 11th Revision (ICD-11) since 2022. Catatonia is found in 5-18% of inpatients on psychiatric units and 3.3% of inpatients on medical units. However, in an unknown number of patients, catatonia remains unrecognized and these patients are at risk of life-threatening complications. Hence, recognizing the symptoms of catatonia early is crucial to initiate appropriate treatment to achieve a favourable outcome. Benzodiazepines such as lorazepam and diazepam, electroconvulsive therapy, and N-methyl-D-aspartate antagonists such as amantadine and memantine, are the cornerstones of catatonia therapy. In addition, dopamine-modulating second-generation antipsychotics (for example, clozapine and aripiprazole) are effective in some patient populations. Early and appropriate treatment combined with new screening assessments has the potential to reduce the high morbidity and mortality associated with catatonia in psychiatric and non-psychiatric settings.

RESUMO

Catatonia is a complex syndrome with unique cognitive, psychomotor, and mood features. Mannerisms and stereotypies are catatonic signs that have been extensively observed and described in the literature, mostly in the context of movements or motor acts. Stereotypies are commonly described as repetitive psychomotor or verbal acts with the abnormality not inherent in the act but in its frequency. Mannerisms, like stereotypies, are repetitive psychomotor or verbal acts, but they are fundamentally odd in nature. Recently, several reports have described these phenomena in the context of complex behaviors, such as eating and drinking. Identification and appreciation of personal and cultural norms, in addition to a careful analysis of behavioral processes and actions, are important tools for clinicians to identify these potentially elusive and often missed patterns of behavior in patients with catatonia. We present the case of a 30-year-old male with a psychiatric history of treatment-resistant, recurrent major depressive disorder with psychotic features who presented to the inpatient psychiatric unit with signs of catatonia, including repeated, purposeless eating. The patient's chart was reviewed, and a literature review was conducted using PubMed with the keywords catatonia, stereotypies, mannerisms, and hyperphagia. The patient, who was diagnosed with catatonia and expressed hyperphagia as a stereotypy, responded to lorazepam. This case shows that hyperphagia may present as a stereotypy in patients with catatonia.

RESUMO

BACKGROUND: Anxiety disorders are highly prevalent and socio-economically costly. Novel pharmacological treatments for these disorders are needed because many patients do not respond to current agents or experience unwanted side effects. However, a barrier to treatment development is the variable and large placebo response rate seen in trials of novel anxiolytics. Despite this, the mechanisms that drive placebo responses in anxiety disorders have been little investigated, possibly due to low availability of convenient experimental paradigms. We aimed to develop and test a novel protocol for inducing placebo anxiolysis in the 7.5% CO2 inhalational model of generalized anxiety in healthy volunteers. METHODS: Following a baseline 20-minute CO2 challenge, 32 healthy volunteers were administered a placebo intranasal spray labelled as either the anxiolytic "lorazepam" or "saline." Following this, participants surreptitiously underwent a 20-minute inhalation of normal air. Post-conditioning, a second dose of the placebo was administered, after which participants completed another CO2 challenge. RESULTS: Participants administered sham "lorazepam" reported significant positive expectations of reduced anxiety (P = .001), but there was no group-level placebo effect on anxiety following CO2 challenge post-conditioning (Ps > .350). Surprisingly, we found many participants exhibited unexpected worsening of anxiety, despite positive expectations. CONCLUSIONS: Contrary to our hypothesis, our novel paradigm did not induce a placebo response, on average. It is possible that effects of 7.5% CO2 inhalation on prefrontal cortex function or behavior in line with a Bayesian predictive coding framework attenuated the effect of expectations on subsequent placebo response. Future studies are needed to explore these possibilities.

RESUMO

BACKGROUND: Catatonia is a highly prevalent syndrome in patients presenting with major neurocognitive disorders (dementia). In this study, we aim to provide a comprehensive description of the clinical and therapeutic aspects of catatonia in patients with dementia. METHOD: This descriptive study, conducted between September 2015 and June 2022, collected data from 25 patients diagnosed with dementia, out of 143 patients treated for catatonia in our specialized psychiatry department. We collected sociodemographic, clinical and treatment data for each patient. RESULTS: Dementia patients constituted 17% of the catatonic cases. Predominantly female, the cohort had a mean age of 65. Diagnoses included Alzheimer's (4 patients, 17%) and Parkinson's (1 patient, 4%) diseases, Lewy body dementia (5 patients, 21%), vascular dementia (4 patients, 17%) and frontotemporal lobar degeneration (10 patients, 41%). The mean Bush-Francis Catatonia Rating Scale score upon admission was 20/69. Overall, complete remission of catatonia was achieved in 75% of patients (n=18), with only 13% (n=3) responding to lorazepam alone, while others required additional interventions such as electroconvulsive therapy (ECT) and/or amantadine. Vascular dementia was predominantly observed in cases resistant to treatment. CONCLUSION: The findings indicate a frequent co-occurrence of catatonia and dementia, highlighting treatability yet suggesting a potential for resistance to lorazepam, which varies by dementia diagnosis. Investigating the mechanisms underlying this resistance and the variability in treatment response is crucial for developing more precise therapeutic strategies.

RESUMO

BACKGROUND: Dysfunctional sensory gating in anxiety disorders, indexed by the failure to inhibit the P50 event-related potential (ERP) to repeated stimuli, has been linked to deficits in the major inhibitory neurotransmitter γ-aminobutyric acid (GABA). AIMS/METHODS: This study, conducted in 30 healthy volunteers, examined the acute effects of GABAA (lorazepam: 1 mg) and GABAB receptor (baclofen: 10 mg) agonists on P50 measures of auditory sensory gating within a paired-stimulus (S1-S2) paradigm and assessed changes in gating in relation to self-ratings of anxiety. RESULTS: Compared to placebo, lorazepam reduced ERP indices of sensory gating by attenuating response to S1. Although not directly impacting P50 inhibition, baclofen-induced changes in gating (relative to placebo) were negatively correlated with trait but not state anxiety. CONCLUSIONS: These preliminary findings support the involvement of GABA in sensory gating and tentatively suggest a role for GABAB receptor signaling in anxiety-associated gating dysregulation.

RESUMO

PURPOSE: Toxicological analyses of biological samples play important roles in forensic and clinical investigations. Ingested drugs are excreted in urine as conjugates with endogenous substances such as glucuronic acid; hydrolyzing these conjugates improves the determination of target drugs by liquid chromatography-tandem mass spectrometry (LC-MS/MS). In this study, we sought to improve the enzymatic hydrolysis of glucuronide conjugates of five psychoactive drugs (11-nor-9-carboxy-Δ9-tetrahydrocannabinol, oxazepam, lorazepam, temazepam, and amitriptyline). METHODS: The efficiency of enzymatic hydrolysis of glucuronide conjugates in urine was optimized by varying temperature, enzyme volume, and reaction time. The hydrolysis was performed directly on extraction columns. This analysis method using LC-MS/MS was applied to forensic autopsy samples after thorough validation. RESULTS: We found that the recombinant ß-glucuronidase B-One® quantitatively hydrolyzed these conjugates within 3 min at room temperature directly on extraction columns. This on-column method saved time and eliminated the loss of valuable samples during transfer to the extraction column. LC-MS/MS-based calibration curves processed with this method showed good linearity, with r2 values exceeding 0.998. The intra- and inter-day accuracies and precisions of the method were 93.0-109.7% and 0.8-8.8%, respectively. The recovery efficiencies were in the range of 56.1-104.5%. Matrix effects were between 78.9 and 126.9%. CONCLUSIONS: We have established an LC-MS/MS method for five psychoactive drugs in urine after enzymatic hydrolysis of glucuronide conjugates directly on extraction columns. The method was successfully applied to forensic autopsy samples. The established method will have broad applications, including forensic and clinical toxicological investigations.

RESUMO

BACKGROUND: Seizure clusters, prolonged seizures, and status epilepticus are life-threatening neurological emergencies leading to irreversible neuronal damage. Benzodiazepines are current evidence-based rescue therapy options; however, recent investigations indicated the prescription of mainly unsuitable benzodiazepines and inappropriate use of rescue medication. OBJECTIVE: To examine current use, satisfaction, and adverse events concerning rescue medication in patients with epilepsy in Germany. PATIENTS AND METHODS: The study was conducted at epilepsy centres in Frankfurt am Main, Greifswald, Marburg, and Münster between 10/2020 and 12/2020. Patients with an epilepsy diagnosis were assessed based on a questionnaire examining a 12-month period. RESULTS: In total, 486 patients (mean age: 40.5, range 18-83, 58.2 % female) participated in this study, of which 125 (25.7 %) reported the use of rescue medication. The most frequently prescribed rescue medications were lorazepam tablets (56.8 %, n = 71 out of 125), buccal midazolam (19.2 %, n = 24), and rectal diazepam (10.4 %, n = 13). Seizures continuing for over several minutes (43.2 %, n = 54), seizure clusters (28.0 %, n = 35), and epileptic auras (28.0 %, n = 35) were named as indications, while 28.0 % (n = 35) stated they administered the rescue medication for every seizure. Of those continuing to have seizures, 46.0 % did not receive rescue medication. On average, rescue medication prescription occurred 7.1 years (SD 12.7, range 0-66) after an epilepsy diagnosis. CONCLUSIONS: Unsuitable oral benzodiazepines remain widely prescribed for epilepsy patients as rescue medication. Patients also reported inappropriate use of medication. A substantial proportion of patients who were not seizure-free did not receive rescue medication prescriptions. Offering each patient at risk for prolonged seizures or clusters of seizures an individual rescue treatment with instructions on using it may decrease mortality and morbidity and increase quality of life. .

RESUMO

INTRODUCTION: Catatonia, a psychomotor disorder characterized by diverse clinical signs, including stupor and mutism, remains elusive in its causes and a challenge to diagnose. Moreover, it is often underrecognized due to its resemblance to disorders of consciousness. However, when diagnosing catatonia, an antipsychotic medication may exacerbate the condition. The first-line treatment typically includes benzodiazepines and/or electroconvulsive therapy (ECT). CASE REPORT: A 60-year-old woman with systemic lupus erythematosus (SLE) and epilepsy presented with catatonic stupor. Despite stable treatment, she experienced an acute deterioration in consciousness, requiring hospitalization. Her condition improved markedly following a benzodiazepine challenge, as documented on EEG. This improvement was short-lived, but a second benzodiazepine challenge restored her from E1V1M1 (stupor) to E4V5M6 within minutes, as documented by a video recording. The patient was treated with lorazepam 1.5 mg/day orally and did not experience further relapses. DISCUSSION: The diagnosis of catatonia had been based on her scores on the Bush-Francis Catatonia Rating Scale (BFCRS; Screening, 6/14; Severity, 19), despite meeting only two DSM-5 criteria for catatonia (stupor and mutism). The diagnosis was supported by EEG and video documentation, excluding other potential differential diagnoses such as nonconvulsive status epilepticus and encephalopathy. Additional quantitative EEG analyses indicated that benzodiazepine administration increased brainwide alpha and beta band power significantly, suggesting that the benzodiazepine normalized attention, consciousness, and long-range synchronization. This report additionally emphasizes the significance of video recordings in managing catatonia, and it helps in accurately tracking symptoms, documenting comprehensively, and improving patient understanding, which is crucial for treatment adherence.

RESUMO

BACKGROUND: From 2000-2021, U.S. suicide deaths have risen 36 %. Identification of pharmacological agents associated with increased suicide risk and safer alternatives may help reduce this trend. METHODS: An exposure-only within-subject time-to-event pharmacoepidemiologic study of the dynamic association between alprazolam treatment and suicide attempts over 2-years. Parallel analyses were conducted for diazepam, lorazepam and buspirone. Data for 2,495,520 patients were obtained from U.S. private insurance medical claims MarketScan from 2010 to 2019. FINDINGS: Alprazolam was associated with over a doubling of risk of suicide attempts (HR=2.21, 95 % CI=2.06,2.38). A duration-response analysis for the modal dose (0.5 mg) revealed a 5 % increase in suicidal events per additional month of treatment (HR=1.05, 95 % CI=1.04,1.07). Parallel analyses with long-acting (diazepam) and short-acting (lorazepam), found similar associations (diazepam HR=2.87, 95 % CI=2.56,3.21; lorazepam HR=1.83, 95 % CI=1.69,2.00), whereas the non-benzodiazepine anxiolytic, buspirone, showed significantly less risk (HR=1.25, 95 % CI=1.13,1.38), and no increased risk in patients with an attempt history (HR=1.05, 95 % CI=0.70,1.59). INTERPRETATION: This study confirmed an earlier signal linking alprazolam to increased suicide attempt risk. The increased risk extends to benzodiazepines in general, regardless of half-life and risk of withdrawal seizure. Buspirone appears to be a safer treatment than benzodiazepines, particularly in patients at increased risk for suicide.

RESUMO

BACKGROUND: Phenobarbital has been used in the emergency department (ED) as both a primary and adjunctive medication for alcohol withdrawal, but previous studies evaluating its impact on patient outcomes are limited by heterogenous symptom severity. OBJECTIVES: We compared the clinical outcomes of ED patients with moderate alcohol withdrawal who received phenobarbital, with or without benzodiazepines, with patients who received benzodiazepine treatment alone. METHODS: This is a retrospective cohort study conducted at a single academic medical center utilizing chart review of ED patients with moderate alcohol withdrawal between 2015 and 2020. Patient encounters were classified into two treatment categories based on medication treatment: phenobarbital alone or in combination with benzodiazepines vs. benzodiazepines alone. Chi-square test or Fisher's exact was used to analyze categorical variables and the Student's t-test for continuous data. RESULTS: Among the 287 encounters that met inclusion criteria, 100 received phenobarbital, compared with 187 that received benzodiazepines alone. Patients who received phenobarbital were provided significantly more lorazepam equivalents. There was a significant difference in the percentage of patient encounters that required admission to the hospital in the phenobarbital cohort compared with the benzodiazepine cohort (75% vs. 43.3%, p < 0.001). However, there was no difference in admission level of care to the floor (51.2% vs. 52.0%), stepdown (33.8% vs. 28%), or intensive care unit (15% vs. 20%), respectively. CONCLUSIONS: Patients who received phenobarbital for moderate alcohol withdrawal were more likely to be admitted to the hospital, but there was no difference in admission level of care when compared with patients who received benzodiazepines alone. Patients who received phenobarbital were provided greater lorazepam equivalents in the ED.

RESUMO

This review aimed to examine the place of benzodiazepines, specifically lormetazepam, in the treatment of insomnia, including during pregnancy or in patients with psychodermatoses. PubMed was searched for the term "lormetazepam" in association with MeSH terms encompassing anxiety, insomnia/sleep disorders, pregnancy/gestation, and psychodermatoses/skin disorders. English-language articles up to 31 July 2022 were identified. Ad hoc searches for relevant literature were performed at later stages of review development. Multiple randomized, placebo-controlled studies have demonstrated that lormetazepam dose-dependently increases total sleep time, decreases wakefulness over a dosing range of 0.5-2.0 mg, and improves subjective assessments of sleep quality. Lormetazepam is as effective as other benzodiazepines in improving sleep duration and quality, but is better tolerated than the long-acting agents with minimal next-day effects. Benzodiazepines can be used as short-term monotherapy at the lowest effective dose during the second or third trimesters of pregnancy; lormetazepam is also a reasonable choice due to its limited transplacental passage. Insomnia associated with skin disorders or pregnancy can be managed by effective symptom control (especially itching), sleep hygiene, treatment of anxiety/depression, and a short course of hypnotics.

RESUMO

Previous neuroscientific research has expounded on the fundamental role played by emotion during moral decision-making. Negative emotionality has been observed to exert a general inhibitory effect towards harmful behaviors against others. Nevertheless, the downregulation of negative affects at different levels of moral processing (e.g. impersonal versus personal moral dilemmas) alongside its possible interactions with other factors (e.g. perspective taking) hasn't been directly assessed; both of which can assist in predicting future moral decision-making. In the present research, we empirically test (Study 1, N = 41) whether downregulating negative emotionality through pharmacological interventions using lorazepam (a GABA receptor agonist), modulate the permissibility of harm to others -i.e. if participants find it more morally permissible to harm others when harm is unavoidable (inevitable harm moral dilemmas), than when it may be avoided (evitable harm moral dilemmas). Furthermore, using another sample (Study 2, N = 31), we assess whether lorazepam's effect is modulated by different perspective-taking conditions during a moral dilemma task -e.g. "is it morally permissible for you to […]?" (1st person perspective), relative to "is it morally permissible for [x individual] to […]?" (3rd person perspective)-, where the outcome of the different scenarios is controlled. The results of both studies converge, revealing an emotion-dependent, rather than an outcome-dependent, pharmacological modulation. Lorazepam only influenced interpersonal moral judgments when not modulated by the evitable/inevitable condition. Furthermore, there was a significant interaction between perspective-taking and drug administration, as lorazepam exerted a larger effect in modulating moral choices rather than moral judgements.

RESUMO

ABSTRACT: Catatonia is an underrecognized disorder that has been widely described as a psychomotor syndrome, with little emphasis on its thought and cognitive dimensions. The current Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision describes only motor and behavioral presentations, whereas a few catatonia scales describe only one form of thought disorders, which is thought perseveration. Thought blocking, a disorder of the thought process, is characterized by regular interruptions in the thought stream. It was described by several scholars as a sign of schizophrenia, with few reports describing thought blocking in association with catatonia. In this article, we describe the course of a patient with bipolar I disorder who presented with catatonia and demonstrated thought blocking. Her catatonic symptoms and thought blocking improved with the addition of lorazepam, recurred upon lorazepam discontinuation, and improved with resumption of lorazepam, demonstrating a clear on/off phenomenon. This report highlights the importance of recognizing thought and cognitive manifestations of catatonia, as it can enhance recognition and improve treatment.

RESUMO

Psychotropic medications are one of the most prescribed pharmaceuticals in the world. Given their frequent detection and ecotoxicity to the no-target organism, the emission of these medications into environments has gradually draw attention. The study developed a sensitive and reliable analytic method to simultaneously investigate 47 psychotropic medications in four matrices: wastewater, surface water, activated sludge, and sediment by ultra-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (UPLC-ESI-MS/MS). These 47 target analytes include 24 antidepressants, 17 antianxiety drugs, 5 anticonvulsants, and 1 relevant hormone. Solid phase extraction (SPE) was employed to extract analytes from water-phase samples. Ultrasonic Solvent Extraction method with Enhanced Matrix Removal clean-up (USE-EMR) was utilized to extract target compounds from solid-phase samples, which requires more straightforward and convenient procedures than previous methods. The extraction recoveries of all analytes ranged from 80 % to 120 % in these four sample matrices. In this study, The limit of quantitation for 47 psychotropic medications were 0.15 ng/L (estazolam) to 2.27 ng/L (lorazepam), 0.08 ng/L (desvenlafaxine) to 2 ng/L (mianserin), 0.22 ng/g (dry weight, dw) (nordiazepam) to 3.65 ng/g (dw) (lorazepam), and 0.07 ng/g (dw) (carbamazepine) to 2.85 ng/g (lorazepam), in wastewater, surface water, sludge, and sediment, respectively. In addition, the developed method was employed to analyse actual samples in two wastewater treatment plants and their receiving rivers. Carbamazepine, escitalopram, clozapine, desvenlafaxine, diazepam, lamotrigine, sertraline, temazepam, and venlafaxine were nearly ubiquitous in all matrices. Moreover, this study indicated that the inadequate removal efficiencies of psychotropic medications in wastewater treatment plants (WWTPs) had resulted in a persistent discharge of these contaminants from human sources into environments.

RESUMO

The effect of lorazepam in the treatment of catatonia is outstanding and almost immediate. Clinicians are familiar with its effects: mute patients can speak again, akinetic patients can move again and patients with negativism can eat and drink again within usually a short duration of about 10 min to 1-2 h. Fear is often gone after lorazepam administration. While not always effective, the introduction of lorazepam into clinical practice represented a breakthrough and was often life-saving for many patients suffering from catatonia. It is rare to observe such rapid therapeutic effects in other domains of psychiatry. In this narrative review we will briefly look at the past, present and future of lorazepam in the treatment of catatonia. It is gratifying to reflect on the fact that clinicians using the age-old medical practice of observation and empirical treatment succeeded in advancing the management of catatonia 40 years ago. The present evidence shows that the clinical effect of lorazepam in catatonia treatment is excellent and more or less immediate although it remains to be explicitly tested against other substances such as diazepam, zolpidem, clozapine, quetiapine, amantadine, memantine, valproate and dantrolene in randomized clinical trials. In addition, future studies need to answer the question how long lorazepam should be given to patients with catatonia, months or even years? This narrative review promotes the rapid use of lorazepam in the treatment of acute catatonic patients and stipulates further scientific examination of its often impressive clinical effects.
