Catatonia Associated With Systemic Lupus Erythematosus (SLE): A Report of Two Cases and a Review of the Literature

Gaps and Controversies in Catatonia as a Movement Disorder

The term "catatonia" was introduced by German psychiatrist Karl Kahlbaum in 1874. Although historically tied to schizophrenia, catatonia exhibits a diverse range of phenotypes and has been observed in various medical and neuropsychiatric conditions. Its intrinsic movement characteristics and association with hypokinetic and hyperkinetic phenomenologies place catatonia within the purview of movement disorders. Despite the presence of catatonia in psychiatry literature for over 150 years, many gaps and controversies persist regarding its etiopathogenesis, phenomenology, diagnostic criteria, and treatment. The current versions of the International Classification of Diseases (ICD-11) and the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) require clinicians to identify any three signs of 15 (ICD-11) or 12 (DSM-5) for the diagnosis of catatonia. Catalepsy and waxy flexibility are the only motor features with high specificity for the diagnosis. We highlight the gaps and controversies in catatonia as a movement disorder, emphasize the lack of a clear definition, and discuss the inconsistencies in the description of various catatonic signs. We propose the exploration of a bi-axial classification framework similar to that used for dystonia and tremor to encourage the evaluation of underlying etiologies and to guide therapeutic decisions to improve the outcome of these patients. © 2024 International Parkinson and Movement Disorder Society.

Juvenile neuropsychiatric systemic lupus erythematosus: A specific clinical phenotype and proposal of a probability score

OBJECTIVE

Juvenile systemic lupus erythematosus (j-SLE) is a rare chronic auto-immune disease involving several organs. Neuropsychiatric (NP) SLE (NPSLE) is frequent in j-SLE and associated with increased morbidity/mortality. Although NPSLE classification criteria exist, attributing NP features to j-SLE remains a major challenge. The study objective is to thoroughly describe j-NPSLE patients and assist in their diagnosis.

METHODS

This is a 4-year retrospective monocentric study of j-SLE patients. NP events were attributed to j-SLE using standardised diagnostic criteria and multidisciplinary paediatric clinical expertise. Clinical features, brain magnetic resonance imaging (MRI)s and samples analysis including cerebrospinal fluid were assessed. A risk of j-NPSLE score was developed based on multivariable logistic regression analysis.

RESULTS

Of 39 patients included, 44% were identified as having j-NPSLE. J-NPSLE diagnosis was established at the onset of j-SLE in 59% of patients. In addition to frequent kidney involvement (76%) and chilblains (65%), all j-NPSLE patients displayed psychiatric features: cognitive symptoms (82%), hallucinations (76%), depressed mood (35%), acute confused state (18%) and catatonia (12%). Neurological involvement was often mild and nonspecific, with headache (53%) in about half of the patients. The main features reported on brain MRI were nonspecific T2/FLAIR white matter hyperintensities (65%), and cerebral atrophy (88%). Upon immunosuppressive treatment, clinical improvement of NP features was observed in all j-NPSLE patients. The score developed to attribute j-NPSLE probability, guide further investigations and appropriate treatments is based on hallucinations, memory, sleep and renal involvement (Sensitivity: 0.95 Specificity: 0.85). Cerebrospinal fluid (CSF) neopterin assessment increases the score sensitivity and specificity.

CONCLUSION

Physicians should carefully and systematically assess the presence of NP features at diagnosis and early stages of j-SLE. For j-NPSLE patients with predominant psychiatric features, a multidisciplinary collaboration, including psychiatrists, is essential for the diagnosis, management and follow-up.

Antipsychotics reduces mortality in patients with neuropsychiatric systemic lupus erythematosus: a retrospective study of psychiatric consultation cases

Objective

This study aimed to identify the presence of psychiatric comorbidities as well as investigate the relationship between psychiatric interventions for mental symptoms and mortality in patients with systemic lupus erythematosus (SLE).

Method

We retrospectively evaluated the records of 160 inpatients with SLE who required psychiatric consultation for further therapeutic intervention from 2013 to 2020 in a tertiary general hospital. We collected clinical data, including diagnoses, medications, and mortality rate. We compared clinical characteristics among the diagnosis groups and correlations between variables.

Results

A total of 138 (86.3%) patients met the diagnostic criteria for at least one mental disorder, with the most common being delirium (54.4%). The average Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score significantly differed among the diagnosis groups (p = 0.003). The mortality rate among patients with delirium was significantly higher than that in the other patient groups (x2 = 12.967, p = 0.024). SLEDAI-2K score was not significantly correlated with mortality (r = 0.123, p = 0.087). Antipsychotics use was associated with mortality (odds ratio 0.053, p = 0.021).

Conclusion

Antipsychotic use may decrease death risk for patients with NPSLE. Early psychiatric consultation is necessary for patients with SLE who have developed or have suspected psychiatric symptoms in order to establish a comprehensive intervention plan.

Malignant Catatonia: A Review for the Intensivist

Catatonia is a clinical syndrome characterized by psychomotor, neurological and behavioral changes. The clinical picture of catatonia ranges from akinetic stupor to severe motoric excitement. Catatonia can occur in the setting of a primary psychiatric condition such as bipolar disorder or secondary to a general medical illness like autoimmune encephalitis. Importantly, it can co-occur with delirium or coma. Malignant catatonia describes catatonia that presents with clinically significant autonomic abnormalities including change in temperature, blood pressure, heart rate, and respiratory rate. It is a life-threatening form of acute brain dysfunction that has several motoric manifestations and occurs secondary to a primary psychiatric condition or a medical cause. Many of the established predisposing and precipitating factors for catatonia such as exposure to neuroleptic medications or withdrawal states are common in the setting of critical illness. Catatonia typically improves with benzodiazepines and treatment of its underlying psychiatric or medical conditions, with electroconvulsive therapy reserved for catatonia refractory to benzodiazepines or for malignant catatonia. However, some forms of catatonia, such as catatonia secondary to a general medical condition or catatonia comorbid with delirium, may be less responsive to traditional treatments. Prompt recognition and treatment of catatonia are crucial because malignant catatonia may be fatal without treatment. Given the high morbidity and mortality associated with malignant catatonia, intensivists should familiarize themselves with this important and under-recognized condition.

Plasmapheresis for a Patient with Catatonia and Systemic Lupus Erythematosus: A Case Report and Literature Review

Neuropsychiatric systemic lupus erythematous (NPSLE) encompasses various psychiatric and neurological manifestations that develop in patients with systemic lupus erythematous (SLE), secondary to the involvement of the central nervous system (CNS). Although neuropsychiatric manifestations are commonly described in NPSLE, catatonia has been less frequently reported in patients with SLE. The roles of benzodiazepines (BZDs), immunosuppression, therapeutic plasma exchange (TPE), and electroconvulsive therapy (ECT) have all been reported in the management of catatonia. Furthermore, another research reported that catatonic symptoms associated with NPSLE were considerably improved by TPE. We, herein, report a case of catatonia in a patient with newly diagnosed NPSLE who exhibited a favorable prognosis through the early initiation of systemic immunosuppressants and TPE. Furthermore, we have reviewed the literature on the role of medication and plasmapheresis (PP), or TPE, in the treatment of catatonia that is associated with SLE.

Catatonia in systemic lupus erythematosus: case based review

Catatonia is a rare psychomotor syndrome characterized by stupor, posturing and echophenomena. It can be associated with schizophrenia, infections, drugs and autoimmune causes like anti N-methyl D-aspartate (NMDA) receptor encephalitis and systemic lupus erythematosus (SLE). Here we report two cases of systemic lupus erythematosus with catatonia, who improved with immunosuppressive treatment and review the cases described in the literature. The first case presented with fever, pancytopenia, toxic epidermal necrolysis (TEN)-like rash and later developed catatonia and macrophage activation syndrome (MAS). The second case presented with acute cutaneous lupus erythematosus (ACLE), fever, alopecia, polyarthralgias, nephritis, cytopenias along with catatonia. Successful management of this syndrome requires prompt recognition and treatment with immunosuppression as well as benzodiazepines with or without electroconvulsive therapy (ECT).

Use of Electroconvulsive Therapy in Autism

The mechanism of action of electroconvulsive therapy (ECT) is not fully elucidated, with prevailing theories ranging from neuroendocrinological to neuroplasticity effects of ECT or epileptiform brain plasticity. Youth with autism can present with catatonia. ECT is a treatment that can safely and rapidly resolve catatonia in autism and should be considered promptly. The literature available for ECT use in youth with autism is consistently growing. Under-recognition of the catatonic syndrome and delayed diagnosis and implementation of the anticatatonic treatment paradigms, including ECT, as well as stigma and lack of knowledge of ECT remain clinical stumbling blocks.

A Case of Prolonged Catatonia Caused by Sjögren's Syndrome

Sjögren's syndrome (SS) is a chronic autoimmune disorder, often associated with some neuropsychiatric symptoms as well as systemic lupus erythematosus. Although catatonia is frequently reported in patients with systemic lupus erythematosus, it has been rarely reported in patients with SS. Herein, we present a case of SS with catatonia effectively and safely treated with modified electroconvulsive therapy (ECT). A 58-year-old woman showed prolonged catatonia and depressive mood along with pathologically dried eye and mouth. Based on physical findings and blood tests, she was diagnosed with SS. Because of the presence of pressure sores, we were unable to perform lumbar puncture for the diagnosis of abacterial encephalitis. Alternatively, single-photon emission computed tomography of her brain revealed multifocal hypoperfused areas in the parietotemporal region. Consequently, we performed ECT for the treatment of catatonia comorbid with SS. Following 20 sessions of ECT, the catatonia was improved without obvious adverse effects. One week after the last ECT, elevated levels of interleukin-6 were identified in the cerebral fluid. After receiving steroid pulse therapy, she has not experienced catatonia for more than 5 years. SS can cause catatonia, and ECT is a safe and effective option for the treatment of catatonia with SS.

Electroconvulsive Therapy for Patients with Catatonia: Current Perspectives

Catatonia is a serious, common syndrome of motoric and behavioral dysfunction, which carries high morbidity and mortality. Electroconvulsive therapy (ECT) is the definitive treatment for catatonia, but access to ECT for the treatment of catatonia remains inappropriately limited. Catatonia is observable, detectable, and relevant to various medical specialties, but underdiagnosis impedes the delivery of appropriate treatment and heightens risk of serious complications including iatrogenesis. Current understanding of catatonia's pathophysiology links it to the current understanding of ECT's mechanism of action. Definitive catatonia care requires recognition of the syndrome, workup to identify and treat the underlying cause, and effective management including appropriate referral for ECT. Even when all of these conditions are met, and despite well-established data on the safety and efficacy of ECT, stigma surrounding ECT and legal restrictions for its use in catatonia are additional critical barriers. Addressing the underdiagnosis of catatonia and barriers to its treatment with ECT is vital to improving outcomes for patients. While no standardized protocols for treatment of catatonia with ECT exist, a large body of research guides evidence-based care and reveals where additional research is warranted. The authors conducted a review of the literature on ECT as a treatment for catatonia. Based on the review, the authors offer strategies and future directions for improving access to ECT for patients with catatonia, and propose an algorithm for the treatment of catatonia with ECT.

Medical Etiologies of Secondary Psychosis in Children and Adolescents

This is an updated review of child and adolescent somatic disorders associated with psychosis/psychotic symptoms, organized into neurologic, infectious, genetic, inborn errors of metabolism, autoimmune, rheumatologic, endocrine, nutritional, metabolic, and iatrogenic categories. When possible clinical manifestations or types of psychotic symptoms and proposed neuropathogenesis causing the neuropsychiatric symptoms are included. In some cases, the psychiatric symptoms may be the first presentation of the disease. The authors hope that this review will aid child and adolescent psychiatrists in considering alternative etiologies of youth presenting with psychosis and encourage appropriate physical examination, history, and further work-up when suspected.
