Abstract
NMDA-R encephalitis is an autoimmune encephalitis that is known to be associated with ovarian teratomas. Eighty to 100 % of patients initially present with neuropsychiatric symptoms. Early recognition and intervention are critical to management and prognosis. This case demonstrates non-specific presenting symptoms of NMDA-R encephalitis. A 32-year-old woman presented to the emergency room with headache, nausea, vomiting, and photophobia. She was discharged with probable aseptic meningitis. Eight days later, she represented with delusional thought content, perseverative speech, and bizarre behavior. Cerebrospinal fluid studies showed elevated protein and mild pleocytosis. A computed tomography scan with contrast showed a 35-mm complex cystic lesion in the right adnexa, which was resected. Confirmatory pathology showed a mature cystic teratoma. Paraneoplastic panel later resulted positive for NMDA-R encephalitis. The patient was treated with methylprednisolone, IVIG, plasmapheresis, and rituximab. The clinical course was complicated by a hypersensitivity reaction to rituximab, non-convulsive status epilepticus requiring intubation, dysphagia requiring a PEG placement, a rectal ulcer causing acute blood loss anemia requiring multiple blood transfusions, bilateral hearing loss, and a left lung pneumothorax. The patient's mood, cognition, and motor function were favorably improving 19 months after diagnosis. This case illustrates presenting signs of NMDA-R encephalitis in a young woman as headache and altered mental status followed by psychosis and epilepsy. Treatment should involve a multidisciplinary team and be individualized and escalated in patients with worsening clinical status refractory to first-line therapy. Further research is warranted to understand the optimal treatment strategy for this disease.

Abstract
BACKGROUND For patients with neuronal surface antibody-associated autoimmune encephalitis (NSAE) whose clinical symptoms gradually improve, the recommended course of immunotherapy in China is about 6 months. We aim to explore the relationship between persistent antibody positivity when immunotherapy is discontinued at 6 months and subsequent relapse. METHODS Prospective inclusion of NSAE patients with clinical remission after 6-month immunotherapy. Their antibody titers and other clinical data were collected at onset and 6 months later. Based on the antibody test results at 6 months, patients were divided into an antibody-persistent group and an antibody-negative conversion group, and then the rate of relapse between the two groups were compared. RESULTS The study included 28 NSAE patients who were antibody-positive at diagnosis. After 6-month immunotherapy, there were 16 (57.1%) cases with persistent antibodies and 12 (42.9%) cases with antibody-negative conversion. In the acute phase of onset, seizures were more common in patients with persistent antibodies (87.5% vs. 50.0%, p = 0.044). During a mean follow-up period of 22 months, patients with persistent antibodies were more likely to experience relapse than those with antibody-negative conversion (37.5% vs. 0.0%, p = 0.024). There were no significant differences in antibody types, CSF findings, results of MRI and EEG, tumor combination, immunotherapy, and long-term outcome between the two groups (p > 0.05). CONCLUSIONS For patients with persistent antibodies when immunotherapy is discontinued at 6 months, persistent antibody positivity was associated with a higher relapse rate.

Abstract
We reported a case of ovarian teratoma-associated Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis with recurrent epileptic seizures and disturbance of consciousness. Although surgical excision of the tumor remains the established standard of care, unlike other reported cases, the patient exhibited limited response to early oophorocystectomy, as well as IVIG and steroid therapy; however, a favorable response was observed with Plasma exchange (PE) initiated on postoperative day 12. Literature review revealed no definite recommended surgical extent for ovarian teratomas, and outstanding improvement in patients with anti-NMDAR encephalitis following PE. Our case raises the question regarding the optimal surgical extent for tumor resection, necessitating careful consideration when deciding between oophorectomy and adnexectomy as the preferred surgical procedure for anti-NMDAR encephalitis in female teens and adults. Furthermore, for refractory patients who fail to respond following tumor resection, PE can be performed early instead of immediately initiating second-line therapy.

Abstract
Autoimmune diseases arise from atypical immune responses that attack self-tissue epitopes, and their development is intricately connected to the disruption of the JAK-STAT signaling pathway, where SOCS proteins play crucial roles. Conditions such as autoimmune uveitis, psoriasis, lupus, and autoimmune encephalitis exhibit immune system dysfunctions associated with JAK-STAT signaling dysregulation. Emerging therapeutic strategies utilize JAK-STAT inhibitors and SOCS mimetics to modulate immune responses and alleviate autoimmune manifestations. Although more research and clinical studies are required to assess their effectiveness, safety profiles, and potential for personalized therapeutic approaches in autoimmune conditions, JAK-STAT inhibitors and SOCS mimetics show promise as potential treatment options. This review explores the action, effectiveness, safety profiles, and future prospects of JAK inhibitors and SOCS mimetics as therapeutic agents for psoriasis, autoimmune uveitis, systemic lupus erythematosus, and autoimmune encephalitis. The findings underscore the importance of investigating these targeted therapies to advance treatment options for individuals suffering from autoimmune diseases.

Abstract
Resection of an underlying ovarian teratoma in patients with N-Methyl-d-Aspartate receptor (NMDAR)-antibody encephalitis is supported by pathophysiological studies demonstrating the production of NMDAR antibodies within the teratoma. This systematic review assesses the clinical effect of teratoma resection and compares early versus late resection. Literature search was performed on the first of October 2022 (MEDLINE, Embase, CENTRAL, Web of Science). Original studies including more than three patients with NDMAR encephalitis and associated ovarian teratoma were included and evaluated with the Study Quality Assessment Tool for risk of bias. Fourteen studies referring to 1499 patients were included and analyzed in four syntheses using the fixed Mantel-Haenszel method. The rate of relapse in patients with ovarian teratoma resection was lower than in patients without resection (risk ratio for relapse 0.30, 95% CI 0.17-0.51), however the certainty level of evidence is very low. Despite some evidence pointing to a beneficial effect of early teratoma resection in patients with NMDAR-antibody encephalitis, systematically accessible data are insufficient to provide recommendations for or against resection, as well as for timing of surgery. The authors received no financial support for the research, authorship, or publication of this article. For the systematic review no clinical-trial database registration had been done.

Abstract
A previously fit and healthy 39-year-old woman was admitted to our tertiary referral hospital with coexisting autoimmune encephalopathy and ovarian tumor. Due to the presence of anti-N-methyl-d-aspartate receptor (anti-NMDAR) in the cerebrospinal fluid, a diagnosis of anti-NMDAR encephalitis was first suggested after ruling out other etiologies. Thus, a laparoscopy was promptly performed to remove the ovarian tumor. The histological endpoint revealed an ovarian teratoma. Consequently, the patient recovered completely in good health condition after 2 months in a coma status. Herein, we report an uncommon case of anti-NMDAR encephalitis associated with ovarian teratoma at our hospital, thus raising awareness of physicians.

Abstract
Ovarian dermoid cysts, also called mature cystic teratomas (MCTs), account for 69% of ovarian germ cell tumors in young women. The tumors are formed by tissues derived from three germ layers, and sebaceous materials are most commonly seen. The origin of MCTs is widely considered to be the germ cell origin, which completes meiosis I. The clinical symptoms vary widely, but 20% of tumors could be asymptomatic. The diagnosis of MCTs is usually made without difficulty by ultrasound and confirmed by histopathology post-operatively. The imaging findings have a high diagnostic value. The typical characteristics present in the sonographic images, including a dermoid plug or Rokitansky nodule, are considered strong evidence for a teratoma. Although the malignant transformation of MCTs is rare, it can occur in some cases, especially in women of advanced age. The treatment of MCTs depends on the risk of malignancy, the age of the patient, and the patient's fertility reserve requirement. In this article, we review the epidemiology, clinical symptoms, diagnosis criteria, cellular origin, and treatment of mature cystic teratomas.

Abstract
BackgroundFor patients with anti-N-methyl-D-aspartate receptor encephalitis (NMDARE) and ovarian teratoma, “conservative” surgical approaches (complete or partial unilateral oophorectomy or bilateral partial oophorectomies) are associated with clinical improvement. “Aggressive” ovarian resections (complete bilateral oophorectomy or “blind” ovarian resections without pre-operative evidence of teratoma) are also reported, although the evidence supporting these approaches is unclear.ObjectiveTo compare the one-year functional outcomes of patients with NMDARE who underwent conservative vs. aggressive ovarian resections.MethodsPatients with NMDARE undergoing ovarian resection between January 1st, 2012 and December 31st, 2021 were retrospectively identified from three North American tertiary care centers. Primary outcome was a modified Rankin Scale score of 0–2 one year after ovarian resection. Fisher exact and Wilcoxon rank sum tests were used to compare demographic features, disease characteristics, and functional outcomes between the two surgical groups. A fixed-effects meta-analysis of studies reporting functional outcomes based on surgical approach was also performed.ResultsTwenty-three patients were included. Eight underwent aggressive surgical management. There was a non-significant trend toward an association between aggressive surgical management and younger age-at-onset, higher baseline disease severity, and longer delays to treatment. There was no difference between “aggressive” (3/8, 38%) and “conservative” (11/15, 73%) management groups in achieving the primary outcome (OR95% = <0.1–1.9; p = 0.18). Findings were similar when considering data from 52 patients in two published studies (RR = 0.74; CI95% = 0.48–1.13; p = 0.16).ConclusionsAggressive ovarian resection was not associated with improved outcomes in patients with NMDARE in this series. Group differences may have contributed, recognizing that patients who underwent aggressive resection tended to be sicker, with procedures performed later in the disease course. Based on available evidence, we advocate for function-sparing resection in patients with imaging-confirmed/suspected teratoma, and repeated multi-modal imaging in at-risk patients with NMDARE refractory to conventional treatment.

Evaluating the incidence and predictors of anti-NMDAR encephalitis in a contemporary cohort of patients diagnosed with dermoid tumors: A national inpatient sample analysis. J Clin Neurosci 2022; 102:109-113. [PMID: 35777113 DOI: 10.1016/j.jocn.2022.06.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 06/02/2022] [Accepted: 06/24/2022] [Indexed: 10/17/2022]
Abstract
INTRODUCTION Anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis is a form of encephalitis previously associated with dermoid tumors. However, most studies in the literature evaluating the disease are case reports and small patient cohorts, limiting robust statistical analysis. Here, we demonstrate predictors of anti-NMDAR encephalitis in a large cohort of US patients. METHODS We used the 2016 National Inpatient Sample (NIS) to identify a cohort of 24,270 admitted for an ovarian dermoid tumor. Of these patients, 50 (0.21%) were diagnosed with anti-NMDAR encephalitis. Patient demographics, hospital characteristics, length of stay (LOS), and complications were collected. Statistical analysis consisted of odds ratios with chi-square testing to compare categorical variables. RESULTS The mean age of all patients with dermoid tumors was 45.5 ± 18.0 years, and the mean age of patients with diagnosed anti-NMDAR encephalitis was 27.4 ± 4.9 years. The mean LOS in the dermoid tumor cohort was 3.5 ± 4.9 days, while the mean LOS in the anti-NMDAR encephalitis cohort was 31.9 ± 25.9 days (p < 0.001). The mean cost in the dermoid tumor cohort was $44,813.18±$54,305.90, while the mean cost in the anti-NMDAR encephalitis cohort was $445,628.60±$665,423.40 (p < 0.001). Patients with age above 30 years with dermoid tumors had significantly lower odds of developing anti-NMDAR encephalitis compared to patients younger than 30 years (OR: 0.19; 95%CI: 0.045-0.67; p-value: 0.003). White patients had significantly lower odds of developing anti-NMDAR encephalitis (OR: 0.19; 95%CI: 0.026-0.77; p-value: 0.013), and Black patients had significantly higher odds of developing anti-NMDAR encephalitis (OR: 3.45; 95%CI: 1.00-12.46; p-value: 0.044). CONCLUSION Patient predictors of developing anti-NMDAR encephalitis include age, race, ethnicity and patients who go on to develop anti-NMDAR encephalitis have a significantly increased hospital LOS and cost compared to those who do not. Future research, including multi-center clinical trials and longitudinal data, is necessary to fully cement the findings of this manuscript.

Abstract
BACKGROUND Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a rare but important complication of ovarian teratoma. Between July 2012 and December 2019, six patients with ovarian teratoma-associated anti-NMDAR encephalitis were enrolled in our hospital and their clinical characteristics, treatment, and follow-up were reviewed. We also conducted a systematic literature review of ovarian teratoma related anti-NMDAR encephalitis reports between January 2014 and December 2019.
AIM To better understand anti-NMDAR encephalitis through literature review and patients enrolled in our hospital.
METHODS The six patients enrolled in the study were those diagnosed with anti-NMDAR encephalitis. Their history, clinical manifestations, and medications were recorded and optimum treatment provided in addition to maintaining a record of the follow-ups. In addition, we also extensively surveyed the literature and provide summarized data from 155 published cases of anti-NMDAR encephalitis from 130 case reports. PubMed and Scopus were the sources of these publications and the time period covered was 6 years ranging from January 2014 through December 2019.
RESULTS The six patients enrolled for this study presented with typical symptoms resulting in a diagnosis of ovarian teratoma induced anti-NMDAR encephalitis. Appropriate interventions led to a positive outcome in all the patients, with five of six patients reporting full recovery and the sixth patient recovering with a few deficits. No death was recorded. The literature survey comprising of 155 patients cases across 130 case reports of anti-NMDAR encephalitis clearly indicated an upward trend in the reports/diagnosis in China, particularly in the surveyed time from 2014 through 2019. The majority of patients (150/155) underwent surgical intervention resulting in positive outcome. No treatment intervention was mentioned for one case while the four patients who were not surgically operated succumbed to the disease.
CONCLUSION Suspected anti-NMDAR encephalitis should be quickly evaluated for anti-NMDAR antibodies since early diagnosis is important. In case of a tumor, its earliest and complete removal is recommended. Finally, early use of corticosteroids and IgG-depleting strategies (intravenous immunoglobulin or plasma exchange) may improve outcome.

Abstract
Paraneoplastic neurological syndromes (PNSs) are a group of neurological disorders triggered by an underlying remote tumor. Ovarian teratoma (OT) is the most common histologic type of germ cell tumor in females. The most common PNSs associated with OT is anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. However, with the increasing number of new antibodies reported over the last decade, the clinical spectrum of OT-related PNSs is also expanding. Our knowledge of OT-related PNSs is still far from complete. Here, we provide a comprehensive review of the most recent findings in the field of OT-related PNSs, with a particular focus on their clinical and pathological characteristics. Overall, the description of neuronal antibodies in PNSs associated with OT strongly suggests that antibodies may be responsible for the clinical symptoms in some cases. OT-related PNSs are associated with various clinical manifestations, including anti-NMDAR encephalitis, limbic encephalitis, encephalomyelitis, progressive cerebellar syndrome and opsoclonus-myoclonus syndrome. The pathological characteristics of the OT suggest that the mechanism of PNSs is probably due to heteromorphic neurons in the tumor tissue, the ectopic expression of the antigens in neural tissue within the teratomas and patients' unusual immune response. Despite the severity of the neurological syndromes, most patients with OT-related PNSs showed good neurologic response to early tumor resection combined with immunotherapy. To further advance the management of OT-related PNSs, additional studies are needed to explore this complex topic.

J Pediatr Adolesc Gynecol 2022; 35:400-403. [PMID: 34863950 DOI: 10.1016/j.jpag.2021.11.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2021] [Revised: 10/19/2021] [Accepted: 11/15/2021] [Indexed: 01/17/2023]
Abstract
BACKGROUND Ovarian teratoma has an uncommon association with anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis. This is a life-threatening condition, and here, we describe a case of an adolescent girl with anti-NMDAR encephalitis caused by an ovarian teratoma. CASE A 14-year-old girl presented with acute features of fever, severe headache, altered behavioral changes, delirium, autonomic instability, episodes of seizure, and involuntary movement over a period of 1 month. Upon investigation, electroencephalogram (EEG), computed tomography (CT), and magnetic resonance imaging (MRI) of her brain showed normal findings. Her serum and cerebrospinal fluid were positive for anti-NMDARs, and a diagnosis of anti-NMDAR encephalitis was made, so she received a course of intravenous methyl prednisolone and immunoglobulin and was discharged after her neurological status improved. Upon further workup, she was suspected to have a left ovarian dermoid cyst on transabdominal ultrasonogram, which was an incidental finding. Her tumor marker panel showed normal serum lactate dehydrogenase, beta human chorionic gonadotropin, inhibin, alpha-fetoprotein, and carcinoembryonic antigen and a cancer antigen 125 level of 71.5 U/L. She eventually underwent laparoscopic left ovarian cystectomy and received immunotherapy in the postoperative period. She was discharged in stable condition on postoperative day 4. On histopathological examination, the specimen revealed a mature cystic teratoma with glial component. One year after surgery, the patient has recovered completely and has no residual psychiatric or neurological symptoms. CONCLUSION Complete recovery after surgery in cases of anti-NMDAR encephalitis with ovarian teratoma emphasizes the need for early recognition of the entity, search for underlying tumor, and tumor removal to improve the prognosis.

Anti-NMDA Receptor Encephalitis: Retrospective Analysis of 15 Cases, Literature Review, and Implications for Gynecologists. JOURNAL OF HEALTHCARE ENGINEERING 2022; 2022:4299791. [PMID: 35340259 PMCID: PMC8941556 DOI: 10.1155/2022/4299791] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Accepted: 12/27/2021] [Indexed: 11/17/2022]
Abstract
Background Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis is a rare form of autoimmune encephalitis caused by anti-NMDA receptor antibodies. This disease mainly affects women of childbearing age and is commonly associated with ovarian teratoma. However, the relationship between anti-NMDA receptor encephalitis and ovarian teratoma and the role of anti-NMDA receptor antibody in the relationship remain unclear. Objectives This study aimed to describe 15 cases of anti-NMDA receptor encephalitis (5 with ovarian teratoma), review literature, and reinforce the gynecologist's knowledge of this disorder. Methods Clinical data of 15 patients from January 2015 to December 2020 admitted to The Second Hospital of Hebei Medical University were collected and analyzed. The diagnosis of anti-NMDA receptor encephalitis was based on the presence of anti-NMDA receptor antibodies in cerebrospinal fluid (CSF) and/or serum. Laparoscopic teratoma removal was performed in patients with ovarian teratoma. All patients had received immunotherapy. In addition, a review of the literature was performed to reinforce the gynecologist's knowledge of this disorder. Results A total of 15 patients with anti-NMDA receptor encephalitis were screened, of whom 5 patients were confirmed with ovarian teratoma by pathology. The most common symptoms of anti-NMDAR encephalitis with teratoma are fever (5/5, 100%), seizure (5/5, 100%), mental and behavioral disorders (4/5, 80%), and decreased consciousness (4/5, 80%). Conversely, the most common symptoms of patients without teratoma were neuropsychiatric symptoms, including headache (6/10, 60%) and mental and behavioral disorders (7/10, 70%). All patients underwent immunotherapy, including steroids, intravenous immunoglobulin (IVIG), plasma exchange, and cyclophosphamide, and 4 out of 5 patients with ovarian teratomas underwent surgical treatment. All patients had a good outcome after systemic, surgical, and immunotherapy treatment. No patient who underwent surgical treatment developed a recurrence. Conversely, 2 of 10 patients without teratoma developed an anti-NMDA receptor encephalitis recurrence. Conclusions Patients with anti-NMDA encephalitis show severe mental and neurological symptoms. Resection of teratoma is beneficial to the relief or disappearance of symptoms and has a good prognosis. This disorder should be fully recognized by gynecologists, who play an important role in diagnosis and treatment.

Abstract
Background To explore the clinical characteristics and prognosis of autonomic dysfunction and paroxysmal sympathetic hyperactivity (PSH), and evaluate the efficacy of drugs used to suppress PSH episode in anti-NMDAR encephalitis patients. Methods Patients who met the diagnostic criteria of anti-NMDAR encephalitis were enrolled from January 2012 to August 2018 and followed up for 2 years. PSH was diagnosed according to the PSH-Assessment Measure. The demographics data, clinical features, auxiliary tests results, treatments, and outcomes were prospective collected and analyzed. Results A total of 132 anti-NMDAR encephalitis patients were enrolled, of which 27.3% and 9.1% experienced autonomic dysfunction and probable PSH respectively. Cardiac autonomic dysfunction was the most common subtype (77.8%). Patients with a higher incidence of ovarian teratoma, mechanical ventilation, neurological intensive care unit admission, and elevated glucose and NMDAR antibody titer in the CSF were more likely to exhibit autonomic dysfunction or PSH. Episodes of PSH can be suppressed by monotherapy in patients without prior sedative drug use with an efficacy of 90%. No significant difference was observed between the prognosis of patients with or without autonomic dysfunction, or between the PSH versus non-PSH groups after 6 months and even during long-term follow-up. However, patients with cardiac autonomic dysfunction had poor prognosis at 6 months. Conclusion PSH is a common clinical condition in patients with anti-NMDAR encephalitis, especially in severe cases, and can be effectively managed by several drug monotherapies. Despite necessitating longer hospital stay, autonomic dysfunction or PSH do not seem to compromise the neurological recovery of patients.

Abstract
Objective This study aimed to evaluate the clinical characteristics and long-term surgical outcomes of patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis with teratoma. Methods Patients who were admitted to West China Hospital from June 2012 to June 2019 and diagnosed with anti-NMDAR encephalitis were enrolled in the study. Medical records were reviewed prospectively to gather clinical characteristic data. Patients were followed up at long-term every 3 months. Results This study included 192 patients, among whom 21 (10.9%) were detected with having a teratoma. Patients included 20 women, with a mean age of 24.62 ± 7.61 years. Seizure and psychiatric symptoms were the most dominant symptoms in both groups, followed by memory deficits. Central hypoventilation (52.4 vs. 17%, p < 0.001) and decreased consciousness (71.4 vs. 31.3%, p = 0.002) were significantly more frequent in patients with teratoma than in those without. Moreover, the anti-NMDAR antibody titer was higher (p = 0.021) and the baseline modified Rankin scale score was lower (p = 0.004) in patients with teratoma than in those without. First-line immunotherapy was performed in 21 (100%) patients with teratoma and 167 (97.7%) patients without teratoma. All patients with teratoma had the tumor removed. During follow-up, two (9.5%) patients with teratoma and 11 (6.4%) patients without teratoma died, whereas 1 (4.8%) patient with teratoma and 37 (21.6%) patients without teratoma had relapses. Overall, 19 (90.5%) patients with teratoma and 151 (88.3%) patients without teratoma achieved favorable clinical outcomes at the final follow-up. Conclusions With early detection and removal of teratoma, most patients with anti-NMDAR encephalitis and teratoma achieved a favorable long-term prognosis.

Additional Value of [18F]FDG PET/CT in Detection of Suspected Malignancy in Patients with Paraneoplastic Neurological Syndromes Having Negative Results of Conventional Radiological Imaging. J Clin Med 2022; 11:jcm11061537. [PMID: 35329862 PMCID: PMC8949922 DOI: 10.3390/jcm11061537] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Revised: 03/03/2022] [Accepted: 03/09/2022] [Indexed: 11/28/2022] Open
Abstract
Background: Paraneoplastic neurological syndromes (PNS) affecting the CNS (central nervous system) are rare, presenting in less than 1% of all those with cancer. The pathogenesis of paraneoplastic neurological syndromes is not fully understood, but it is presumed to result from an immune attack on the underlying malignancy. The presence of different types of onconeural antibodies may occur in different tumors and can lead to different clinical manifestations, making the early detection of cancers challenging. Aim: An evaluation of [18F]FDG PET/CT in neoplastic tumor detection in patients with paraneoplastic neurological syndromes having negative or unremarkable results of conventional radiological imaging. Methods: Among all patients diagnosed with paraneoplastic neurological syndromes in the Neurology Department in 2016–2020, 15 patients with unremarkable conventional radiological findings who underwent [18F]FDG PET/CT were included in the study. Results: [18F]FDG PET/CT enabled localization of suspected malignancy in 53% (8 of 15) of PNS cases with previous unremarkable conventional radiological findings. Conclusion: [18F]FDG PET/CT may be considered as a useful tool for neoplastic tumor detection in patients with paraneoplastic neurological syndromes, accelerating the diagnostic process and enabling faster initiation of appropriate treatment.

Abstract
BackgroundMechanical ventilation (MV) is commonly used in anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis patients with serious conditions. However, little is known about the potential risk factors and long-term outcomes of anti-NMDAR encephalitis requiring MV, especially prolonged MV.MethodsThe data collected prospectively from 305 patients with anti-NMDAR encephalitis were retrospectively reviewed. The functional outcome was assessed using a modified Rankin scale (mRS) every 3 months.ResultsWe identified 62 (20.3%) patients who required MV. The most common reasons for MV were decreased consciousness and/or status epilepticus (SE). Among 60 patients analyzed, 27 patients required prolonged MV (>15 days). Prolonged MV primarily was based on the younger age, coma, tumor, and severe pneumonia. During the follow-up (median: 28 months, range: 3–87 months), 77% of patients required MV that exhibited a good outcome. In univariate analysis, prolonged MV, higher levels of C-reactive protein (CRP), and neutrophil-to-lymphocyte ratio (NLR) were found to be associated with poor neurological outcome at 6 months. Although the prolonged MV group exhibited a longer time to achieve a good outcome as compared to the short MV group (median duration 6 months vs. 3 months, p = 0.004), no significant difference was observed between the two groups about long-term outcomes.ConclusionIt is important to recognize that most anti-NMDAR encephalitis patients who required MV will achieve a favorable long-term outcomes, despite the longer duration of MV. Our results may help clinicians in the ventilator management of severe anti-NMDAR encephalitis patients.

Abstract
BACKGROUND Autoimmune encephalitis (AE) is a common cause of encephalitis. We review the most recent evidence on this neuroimmune condition and autoantibody testing currently available. CONTENT Clinical criteria, neuroimaging and electroencephalography can facilitate the diagnosis of AE prior to obtaining autoantibody testing results, and lead to a diagnosis of AE even in the absence of a recognized antibody. Early treatment of AE has been found to correlate with improved long-term functional and cognitive outcomes. We suggest a clinical approach to diagnosis based on the predominant area of nervous system involvement and the results of ancillary testing that are widely available. We also propose a 2-tiered approach to the acute management of probable or definite AE. We, finally, provide guidance on the long-term management of AE-a challenging and understudied area. SUMMARY Much work remains to be done to improve the care of patients with AE. As understanding of the pathophysiology and predisposing factors underlying this condition steadily increases, a more evidence-based, targeted approach to the treatment of AE is still desired. Nonetheless, looking at the progress made over the past 2 decades, since the discovery of the first autoantibodies associated with AE, one cannot help but feel optimistic about the road ahead.

Abstract
The majority of patients with anti-N-Methyl-D-Aspartate receptor (NMDAR) encephalitis present with psychiatric symptoms and subsequently develop neurological features. However, isolated psychiatric episodes occur in <5% of affected individuals, less frequent at disease onset (<1%) compared to relapse (4%). We report the case of a previously healthy 24-year-old female who presented with psychotic symptoms and behavioral alterations. Despite therapy, she showed no improvement and subsequently developed catatonic features. While the ancillary tests were normal, the clinical warning signs raised the suspicion of anti-NMDAR encephalitis which we later confirmed. Given its strong association with underlying tumors, we screened the patient and found an ovarian teratoma. Once removed, the patient displayed a substantial improvement in the mental status. Besides being extremely rare, this case illustrates the need to maintain clinical suspicion of anti-NMDAR encephalitis even in the absence of neurological features or paraclinical anomalies.

Abstract
Introduction. Autoimmune encephalitis associated with ovarian teratoma is a
serious and potentially fatal pathology. While this clinical entity is known
to neurologists, the available literature rarely mentions the role of a
gynecologist in diagnostic imagining and treatment. Although several months
have passed from the appearance of the symptoms to surgical treatment, this
case shows that even then a complete recovery is possible. Case
presentation. The patient was a 28-year-old female, brought to the hospital
because a sudden onset of unusual behavior - an acute psychosis with
suicidal thoughts and auditory hallucinations. Soon after the admission she
became delirious, uncooperative and agitated. Blood check, neurological
assessment and cranial computed tomography yielded normal results.
Therefore, a psychiatric disorder was suspected. Electroencephalogram
revealed a diffuse encephalitic insufficiency. As cerebrospinal fluid was
negative for infections, the autoimmune etiology of the disease was
suspected. Abdominal computer tomography showed a complex right ovarian mass
measuring 50 x 40 x 30 mm, confirmed by vaginal ultrasound. Laparoscopy with
right adnexectomy was performed. The pathohistological finding showed a
mature teratoma. In the meantime, the result of the cerebrospinal fluid test
came positive for anti NMDAR antibodies. Six months after surgery, the
patient was in a good mental and neurological status without symptoms.
Conclusion. Gynecologists should be aware of the presence of ovarian tumors
in encephalitis cases. A timely diagnosis of the underlying gynecological
cause of a neurological condition, allows for prompt treatment and can
remarkably improve clinical conditions and, thus, be lifesaving.

Abstract
This is a case of a young woman who developed neurological and psychiatric symptoms 3 days after resection of an immature teratoma. She was diagnosed with anti-NMDA receptor encephalitis via positive serum antibody titres, which was later confirmed with cerebrospinal fluid antibody titres. Given her cancer diagnosis, she underwent treatment with bleomycin, etoposide and cisplatin chemotherapy in addition to 5 days of high-dose steroids (1 g of intravenous methylprednisolone) for the encephalitis. This treatment regimen led to significant clinical improvement 3 weeks after completion of one cycle of chemotherapy.

Abstract
Ovarian teratomas are by far the most common ovarian germ cell tumor. Most teratomas are benign unless a somatic transformation occurs. The designation of teratoma refers to a neoplasm that differentiates toward somatic-type cell populations. Recent research shows a striking association between ovarian teratomas and anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis, a rare and understudied paraneoplastic neurological syndrome (PNS). Among teratomas, mature teratomas are thought to have a greater relevance with those neurological impairments. PNS is described as a neurologic deficit triggered by an underlying remote tumor, whereas anti-NMDAR encephalitis is characterized by a complex neuropsychiatric syndrome and the presence of autoantibodies in cerebral spinal fluid against the GluN1 subunit of the NMDAR. This review aims to summarize recent reports on the association between anti-NMDAR encephalitis and ovarian teratoma. In particular, the molecular pathway of pathogenesis and the updated mechanism and disease models would be discussed. We hope to provide an in-depth review of this issue and, therefore, to better understand its epidemiology, diagnostic approach, and treatment strategies.

Autoimmune encephalitis with antibodies against neuronal cell surface antigens is a group of neuropsychiatric disorders, with anti-N-methyl D-aspartate (NMDAR) encephalitis being one of them. We report a case of a young male patient who presented with complaints of seizures associated with fever, rapidly progressing memory loss, and choreoathetoid movements for 1 month. His serum was strongly positive for anti-NMDAR receptor antibodies. F-18 fluorodeoxyglucose positron-emission tomography/computed tomography for the brain revealed hypermetabolism involving bilateral basal ganglia and bilateral mammillary bodies associated with hypometabolism in bilateral occipital lobes.

[PMID: 34307584 PMCID: PMC8283584 DOI: 10.12998/wjcc.v9.i19.5319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Revised: 04/25/2021] [Accepted: 05/07/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND A population-based comparative study in United States shows that the prevalence and incidence of autoimmune encephalitis are comparable to those of infectious encephalitis and its detection is increasing over time. Some patients are complicated with ovarian teratoma. The younger the patient is, the less likely a tumor will be present.
CASE SUMMARY This case report describes the successful treatment of anti-N-methyl-D-aspartate-receptor (NMDAR) encephalitis by early laparoscopic ovarian cystectomy and immunotherapy in a 4-year-old female child. And to the best of our knowledge, this detailed case report describes the youngest patient to date with anti-NMDAR encephalitis who underwent laparoscopic ovarian cystectomy.
CONCLUSION Although the younger the patient is, the less likely a tumor will be detected, we still emphasize that all patients with suspected or confirmed anti-NMDAR encephalitis should be screened for ovarian tumors if possible. Prompt initiation of immunotherapy and tumor removal are crucial for good outcomes.

Abstract
Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an autoimmune disease frequently associated with ovarian teratomas. In cases where an ovarian teratoma is identified, treatment involves prompt removal of the ovarian teratoma, resulting in significant clinical improvement and decreased incidence of relapse. We present the case of a 14-year-old female patient admitted for progressively worsening psychiatric and neurological status, diagnosed with anti-NMDAR encephalitis, and negative initial imaging for ovarian pathology. She was in the hospital for 8 months requiring admission to the intensive care unit and multiple courses of immunotherapy before clinical improvement. Three months after discharge, she was readmitted with clinical relapse and repeat imaging showed an ovarian teratoma. Removal of the teratoma resulted in sustained clinical improvement with return to baseline and no further relapse. Our case report highlights the importance of maintaining a high suspicion for an underlying ovarian teratoma in a female patient with anti-NMDAR encephalitis, even when initial imaging is negative. Currently, there are limited data on recommendations for repeat imaging. Therefore, we recommend repeat imaging in patients resistant to multiple lines of treatment or presenting with clinical relapse.

Anti-N-Methyl-D-Aspartate Receptor Encephalitis Associated with Ovarian Teratoma in South China-Clinical Features, Treatment, Immunopathology, and Surgical Outcomes of 21 Cases. DISEASE MARKERS 2021; 2021:9990382. [PMID: 34093900 PMCID: PMC8163540 DOI: 10.1155/2021/9990382] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Accepted: 05/08/2021] [Indexed: 11/24/2022]
Abstract
Objective To study the clinical characteristics and surgical outcomes of anti-NMDAR encephalitis and the immunopathology of associated teratomas. Methods Twenty-one patients were enrolled in this retrospective study, who were diagnosed with anti-NMDAR encephalitis with ovarian teratoma and admitted to two tertiary hospitals in South China from July 2014 to December 2019. The clinical data of patients were reviewed. Comparisons were made between the patients with different outcomes after surgery. Immunohistochemical analyses of associated ovarian teratomas were performed. Results The mean age of the patients was 24.33 ± 5.12 years. The peak seasons of disease onset were autumn and winter (30.61% and 32.65%). The symptoms could be divided into 8 categories, including psychiatric abnormalities, seizures, movement dysfunction, consciousness disorders, autonomic dysregulation, speech disturbance, central hypoventilation, and memory deficits. All patients developed four or more categories of symptoms within the first four weeks. Twelve patients (57.1%) had a maximum mRS of 5, and 11 patients (52.4%) were admitted to ICU. Twenty patients received surgery, and only 3 patients were diagnosed pathologically with immature ovarian teratomas, while the other 17 patients had mature ovarian teratomas. After surgery, 17 patients (85.0%) got clinical improvement. The central hypoventilation symptom and mature ovarian teratomas were associated with surgical outcome. Immunohistochemical analysis revealed that there were NMDAR-positive neural tissues in all 8 teratomas and in which 3 cases also contained large numbers of NMDAR-positive sebaceous glands and squamous epithelial tissues. Conclusion The disease is of high prevalence in autumn and winter. The central hypoventilation symptom and mature ovarian teratomas were associated with surgical outcome. NMDAR-positive neural tissue is not the only etiological factor of encephalitis. We speculate that encephalitis development in some patients may result from NMDAR expression in sebaceous glands and squamous epithelial tissues.

Abstract
PURPOSE The purpose of this study was to determine the computed tomography (CT) and magnetic resonance imaging (MRI) characteristics of ovarian mature teratoma in patients with anti-N-methyl-d-aspartate receptor encephalitis (NMDAR-E). MATERIALS AND METHODS A total of 125 women (mean age, 40.9±17.8 [SD] years; age range: 12-85 years) with 146 histopathologically or radiologically proven ovarian mature teratomas who underwent preoperative CT and MRI examinations were retrospectively included. Eight patients with 11 teratomas had NMDAR-E, whereas 117 patients with 135 teratomas did not have NMDAR-E. CT and MRI examinations were retrospectively reviewed and teratomas in patients with NMDAR-E were compared to those in patients without NMDAR-E. Comparisons were performed using Mann-Whitney U test or Fisher exact test. RESULTS In patients with NMDAR-E, maximum diameter of teratomas (26.1±9.3 [SD] mm), prevalence of teeth/calcification (36%) and rate of occupation by fat components (26%) were lower than those in patients without NMDAR-E (67.0±37.6 [SD] mm [P<0.01]; 75% [P<0.05]; and 65%[P<0.01], respectively). More than 75% of space was occupied by fat components in 76/135 teratomas (56%) in patients without NMDAR-E, whereas this was not observed in any teratoma in patients without NMDAR-E. CONCLUSION By comparison with teratomas in patients without NMDAR-E, teratomas in patients with NMDAR-E are smaller, have few teeth/calcification, and the amount of space occupied by fat components is smaller.

Abstract
INTRODUCTION Antibody-mediated encephalitides (AE) with pathogenic autoantibodies (aAB) against neuronal surface antigens are a growing group of diseases characterized by antineuronal autoimmunity in the brain. AE patients typically present with rapidly progressive encephalitis and characteristic disease symptoms dependent on the target antigen. Current treatment consists of an escalating immunotherapy strategy including plasma exchange, steroid application, and B cell depletion. AREAS COVERED For this review, we searched Medline database and google scholar with inclusive dates from 2000. We summarize current treatment strategies and present novel therapeutic approaches of target-specific interventions at the pre-clinical level as well as immunotherapy directed at antibody-induced pathology. Treatment options include modulation of target proteins, intervention with downstream pathways, antibody modification, and depletion of antibody-secreting cells. EXPERT OPINION Although current therapies in AE are effective in many patients, recovery is often prolonged and relapses as well as persistent deficits can occur. Specific immunotherapy together with supportive target-specific therapy may provide faster control of severe symptoms, shorten the disease course, and lead to long-lasting disease stability. Among the various novel therapeutic approaches, modulation of targeted receptors by small molecules crossing the blood-brain barrier as well as prevention of aAB binding is of particular interest.

Co-expression of NMDA-receptor subunits NR1, NR2A, and NR2B in dysplastic neurons of teratomas in patients with paraneoplastic NMDA-receptor-encephalitis: a retrospective clinico-pathology study of 159 patients. Acta Neuropathol Commun 2020; 8:130.

Abstract
Objective To comprehensively describe the pathological features of neurons in patients with ovarian teratomas and paraneoplastic anti-NMDAR encephalitis (anti-NMDARE), emphasizing on NMDA-receptor expression and infiltrating lymphocytes. Methods A retrospective study was performed in a large series of 159 patients from the West China Hospital. We retrospectively identified 12 patients with paraneoplastic anti-NMDARE (11 case with ovarian teratomas and 1 case with mixed germ cell tumor), which were compared to 35 patients with teratomas and no encephalitis and to 147 patients with anti-NMDARE and no evidence for tumors. Patient history and outcome were reviewed from the clinical charts and compared between all three groups. Histopathological examination, including double-immunofluorescence of NMDAR subunits and IgG was performed in all teratoma tissues. Magnetic Luminex Assay Human Premixed Multi-Analyte Kit was performed to investigate cytokines profile of CSF. Results Patients with paraneoplastic anti-NMDARE had a more severe clinical presentation, i.e. they required more mechanical ventilation and intensive care (p < 0.001). Though immunotherapy was initiated earlier in this group, repeated intravenous immunoglobulin administration (IVIG) was more common (p = 0.002) and with higher cerebrospinal fluid (CSF) antibody titres (p = 0.004). Following tumor resection, the outcome did not differ between groups. A peculiar population of floating-frog like dysplastic neurons were observed only in teratomas of patients with paraneoplastic anti-NMDARE, co-expressing NR1, NR2A, NR2B subunits and IgG. Also, CD20 positive B-cells were more common in anti-NMDARE teratomas. In CSF of paraneoplastic anti-NMDARE patients, TNF-α, IL-10 and GM-CSF concentrations were higher than in negative symptom control and VEGF-A and IL-1a were lower than in anti-NMDARE patients (0.25 < p < 0.05). Conclusions Patients with teratomas and paraneoplastic anti-NMDARE revealed a cellular population of dysplastic neurons co-expressing NMDAR subunits, which were the potential source of autoantigens triggering anti-NMDARE. Some inflammatory cytokines may be involved in pathogenesis of paraneoplastic anti-NMDARE.

Abstract
Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a potentially life-threatening but reversible autoimmune disorder characterized by psychiatric symptoms, cognitive dysfunction, speech dysfunction, seizures, movement disorder, decreased level of consciousness, and autonomic dysfunction or central hypoventilation. It occurs predominantly in young women and approximately half of them have underlying tumors, mainly ovarian teratoma. A 24-year old woman was admitted because of fever, headache, abnormal movement and decreased mental status. Five cycles of plasmapheresis improved her neurological and mental status. Anti-NMDAR antibodies in her CSF and serum were positive, and computed tomography revealed a 1-cm sized mass suggestive of mature cystic teratoma arising from the right ovary. We promptly performed laparoscopic right ovarian cystectomy. She was discharged after 2 weeks with mild memory deficit. Prompt removal of ovarian teratoma and multidisciplinary care are particularly important for good outcome.

Abstract
BACKGROUND Anti-NMDA receptor antibody (anti-NMDAr) encephalitis, although still a rare condition, is well known to neurologists as it is the leading cause of non-infectious acute encephalitis in young women. However, this is less well known to gynecologists, who may have a decisive role in etiological management. Indeed, in 30-60% of cases in women of childbearing age, it is associated with the presence of an ovarian teratoma, whose removal is crucial in the resolution of symptomatology. OBJECTIVES Primary objective of our work was to present a review in a very schematic and practical way for gynecologists, about the data on anti-NMDAr encephalitis in terms of epidemiology, clinical symptomatology, treatment and prognosis. The second objective was to propose a decision tree for gynecologists to guide them, in collaboration with neurologists and anesthesiologists, after the diagnosis of NMDAr encephalitis associated with an ovarian mass. METHOD We conducted an exhaustive review of existing data using PubMed and The Cochrane Library. Then, we illustrated this topic by presenting two typical cases from our experience. RESULTS Anti-NMDA antibody encephalitis association with an ovarian teratoma is common, especially in women of reproductive age. Complementary examinations in search of an ovarian teratoma must therefore be systematic to envisage a possible surgical excision that may improve patient prognosis. CONCLUSION Anti-NMDA antibody encephalitis should not be ignored by gynecologists whose role in management is central.
