ABSTRACT
Longitudinally extensive transverse myelitis (LETM) is an infrequent subtype of acute transverse myelitis, which presents with sensory, motor and autonomic dysfunction after a focal or widespread inflammation of the spinal cord due to either direct infection or an autoimmune response. We present case reports of three females who developed LETM following COVID-19 vaccination. Their clinical presentation, deficits and rehabilitation outcome at discharge and at 8 months follow-up have been briefly described.
ABSTRACT
Background: Months after the initial report of an unknown cause of pneumonia outbreak in Wuhan, China, the SARS-COV-2 continues its rampant spread globally. This novel corona virus has been known to cause severe respiratory illness. It is important to be wary of the complications that would soon present at the Out-patient centers after being cured from the infection. Case: This is a case of a 59-year-old, female who came in at the Out-Patient Clinic with progressive bilateral pins and needles sensation of the feet after recovering from COVID-19 infection followed by a sensory level on T7-T10. Case Report: Here we present a case of transverse myelitis as a complication of COVID-19 infection, the first to have occurred after recovery from the virus. With the success of treatments and recoveries, possible post infectious sequelae could be the next wave that could come into the present picture of the pandemic. Conclusion(s): Post infectious transverse myelitis after recovering from COVID-19 is a possibility and that documentation of such cases and other complications must be reported.Copyright © 2022
ABSTRACT
Background: Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune, rare demyelinating disease of the central nervous system characterized by recurrent attacks which usually involve optic nerves and spinal cord. Although the most common symotoms are myelitis and optic neuritis, it can be presented as cerebral syndromes mainly those related to the brain stem and diencephalon. Since NMOSD is a rare disease and the epidemiological data on this disorder is still insufficient, the establishment of registry and long-term follow up studies are needed to assess the disease course and behavior over a period of time. Material(s) and Method(s): We stablished an electronic registry system for NMOSD patients in the MS center of Kashani hospital, Isfahan, Iran, since spring 2016. Every patient suspected for NMOSD and documented in our database was included in a follow up study to monitor their disease course and progression. Anti AQP4 antibody and Anti MOG antibody were checked for all patients in a unique lab by cell based assay method. Demographic data and clinical characteristics such as family history, comorbidities,education, number of relapses, presentation signs and radiological findings were recorded. Moreove, relapses, treatment change, triggers, and COVID-19 infection were documented. We investigated the effect of the COVID19 pandemic and vaccination on NMOSD patients. Result(s): This study included 173 cases with definite diagnosis of NMOSD, and 56 ones were seropositive for AQP4 Ab. 142 were females of which 46 were in the seropositive group. Their mean age was 40.02+/-11.11 years (45.78+/-12.88 in AQP4Ab positive group). The mean of age at disease onset was about 30.16+/-11.90 years. The mean time of follow up was 55.84+/-18.94 months until today. In 76 patients, there were LETM in the first cervical MRI. 123 patients revealedbabnormality in the first brain MRI. 27 patients had hypothyroidism as the most common comorbidity. 36 cases reported positive family history of multiple sclerosis and also 4 had a family history of NMOSD. Conclusion(s): The mean age of onset did not differ between seropositive and seronegative group but it was higher than MS patients. Brain MRI showed abnormality in NMOSD patients. Female/male was 4.4/1 which is lower than other studies.Copyright © 2022
ABSTRACT
Background Vaccinations against SARS-CoV-2 have been a topic of political, social, and medical intrigue since the declaration of the COVID-19 pandemic in early 2020. The vaccine side effects have been relatively mild to date, with few observed systemic effects. Case presentation A 69-year-old previously healthy female presented with symptoms of asymmetric bilateral lower and upper extremity weakness 2 days after vaccination with the Pfizer-BioNTech mRNA vaccine. MRI of the cervical spine revealed a non-compressive myelitis extending from C3-4 to T2-3. Common known causes of transverse myelitis were ruled out by diagnostic techniques. Conclusions Transverse myelitis is a rare autoimmune disorder that has been shown to have a temporal association with vaccination in the past. With a progressively partisan societal view on vaccinations, it is important for clinicians to remain vigilant on documenting potential associations without encouraging fear of causation.Copyright © 2021 The Author(s)
ABSTRACT
Spinal cord affection, according to various sources, is a common complication of a new coronavirus infection. The article describes various variants of spinal cord pathology in COVID-19, their potential mechanisms of development, approaches to treatment and outcomes of the disease. Three patients who were observed at the Research Center of Neurology and represent the most interesting cases of classic transverse myelitis, myelitis with predominant involvement of the lateral and posterior cords, and longitudinal widespread myelitis associated with antibodies to myelin oligodendrocyte glycoprotein (MOG) are considered in detail. These clinical observations demonstrate the importance of early diagnosis and selection of adequate therapy for a favorable outcome of the disease.Copyright © 2022 Ima-Press Publishing House.

ABSTRACT
CONTEXT: Recent literature points towards myelitis, like encephalitis, as a common central nervous system complication of COVID-19. This review elaborates on disorders of the spinal cord caused by the SARS-CoV-2 virus. OBJECTIVES: To review the published data about SARS-CoV-2-associated spinal cord disorders and assess their clinical, neuroimaging, treatment, and prognostic aspects. METHODS: The PubMed and Google Scholar databases were searched for published cases using the search items "COVID-19 OR SARS-CoV-2 AND myelitis", "COVID-19 OR SARS-CoV-2 AND myelopathy", and "COVID-19 OR SARS-CoV-2 AND spinal cord". RESULTS: Thirty-three isolated cases were included in the present review, of which 14 were aged 60 years and above (range: 3-70 years). Eighteen patients had lung abnormalities on chest imaging. Eight patients had developed either an areflexic paraparesis or quadriparesis. In 17 patients, neuroimaging demonstrated longitudinally extensive transverse myelitis, while 3 cases showed neuroimaging changes in the spinal cord as a part of acute disseminated encephalomyelitis syndrome. Cerebrospinal fluid (CSF) examinations revealed inflammatory changes in 18 patients. However, the SARS-CoV-2 virus in the CSF was discovered in 2 patients. In 2 patients, anti-SARS-CoV-2 antibodies were demonstrated in the CSF. Following treatment, 13 patients were able to walk. CONCLUSIONS: A variety of COVID-19-related spinal cord manifestations, such as acute transverse myelitis, acute necrotizing myelitis, SARS-CoV-2 myelitis, acute disseminated encephalomyelitis, neuromyelitis optica spectrum disorder, hypoxic myelopathy, MOG antibody-associated myelitis, spinal cord infarction, and spinal epidural abscess, have been reported. The possible mechanisms of this involvement being direct invasion, cytokine storm, coagulopathy, and an autoimmune response. However, response to treatment has been generally unsatisfactory, with many patients having residual weakness necessitating long-term rehabilitation.
ABSTRACT
Background Vaccination is a recognised trigger of ADEM and approximately 50% paediatric cases have antibodies to MOG. The SARS-CoV-2 mass vaccination programme could therefore trigger cases of MOGAD. Neuromyelitis optica (NMO) is an autoimmune inflammatory condition of the CNS associ- ated with antibodies to AQP4. Method Ten patients (ages 22 - 65 years) with antibodies to MOG or AQP4 were referred to the NHS England NMO service having developed acute onset CNS inflammation within 8 weeks of vaccination. Results Eight patients had MOGAD, seven of whom received the AstraZeneca vaccine (AZV) and one the Pfizer vaccine (PV). Only the post-PV MOGAD patient presented with typical adult-onset phenotype of isolated ON. All post-AZV MOGAD patients presented atypically;85.7% had LETM and 71.4% had intrac- erebral lesions, resembling ADEM more commonly seen in paediatric MOGAD. The atypical presentation supports a causative role of AZV, but the role of PV is less convincing. Two patients had AQP4-NMOSD with typical demographic features. Both received AZV. Less typically, one young adult presented with LETM rather than characteristic young adult ON, the other had a silent short segment myelitis, which is rarely seen in AQP4-NMOSD. Both patients achieved good outcomes. Conclusion We discuss the potential causation and pathophysiological mechanisms.
ABSTRACT
Background: There have been reports of demyelinating syndromes in association with COVID-19 and to a much lesser extent COVID 19 vaccines. The association between demyelination and vaccines, in general, remains controversial. We review a presentation of fulminant demyelination, and discuss antecedent COVID-19 vaccination, the formulation of a broader differential diagnosis and ultimately the pathologic diagnosis. Case presentation: An 80-year-old woman presented with seizure, encephalopathy, quadriparesis and ultimately expired. She received a SARS-CoV-2 vaccine one day prior. Imaging revealed contrast enhancing cerebral lesions, longitudinally extensive transverse myelitis. CSF was markedly inflammatory. Pathologic examination of the CNS lesions revealed demyelination and inflammation beyond white matter, not restricted to a perivenular distribution. Conclusion(s): This case depicts a seemingly fulminant course of a diffuse demyelinating syndrome characterized clinicopathologically as Marburg's variant of multiple sclerosis. There are several unique aspects of this case including the extremely rapid course, the unusual evolution of CSF abnormalities, with hypoglycorrhachia and markedly elevated protein. The proximity to vaccination is a pertinent association to document, though we cannot unequivocally prove causation.Copyright © 2022 The Authors

ABSTRACT
Background: Neurological complications from COVID-19 vaccines are rare Case Report: Herein, we present the case of a previously healthy woman who developed incomplete transverse myelitis (TM) immediately after receiving her first injection of the Pfizer-BioNTech COVID-19 vaccine. Conclusion(s): This case is an example of TM as a first clinical event in the diagnosis of multiple sclerosis triggered by COVID-19 vaccination. A review of the FDA's Vaccine Adverse Event Reporting System (VAERS) reveals similar instances of TM. Clinicians should be aware of this potential complication from COVID-19 vaccination.Copyright © 2022 The Authors
ABSTRACT
Background: The large proportion of coronavirus disease 2019 (COVID-19) patients has been associated with a large number of neu-ropsychiatric manifestations. Despite the high prevalence of COVID-19, few studies have examined such manifestations, especially in children and adolescents. Objective(s): This study investigated neuropsychiatric manifestations in hospitalized children and adolescents admitted for COVID-19 infection in Iran. Method(s): This prospective observational study included admitted children and adolescents (4-18 years old) diagnosed with COVID-19 infection, pediatric neurologists, child and adolescent psychiatrists, and infectious disease specialists, and assessed 375 infected patients during August and December 2021. Result(s): Of the 375 patients, 176 (47%) were female, with a mean age of 9.0 +/- 3.39 years. Psychiatric and neurological manifestations were reported in 58 (15.5%) and 58 (15.5%) patients, respectively. The most prevalent psychiatric disorders were separation anxiety disorder (SAD) (5.1%), major depressive disorder (MDD) (3.5%), generalized anxiety disorder (GAD) (2.7%), insomnia (2.4%), and op-positional defiant disorder (ODD) (2.4%). Regarding neurological complications, seizures were the most prevalent (13.1%), followed by encephalitis (1.9%), transverse myelitis (0.3%), acute ischemic stroke (0.3%), and Guillain-Barre syndrome (0.3%). There was no significant relationship between the duration of COVID-19 infection (P = 0.54) and ICU admission (P = 0.44) with the emergence of psychiatric symptoms. Conclusion(s): The most prevalent neurologic and psychiatric complications among children and adolescents with COVID-19 infection were seizures and the symptoms of anxiety/mood disorders, respectively.Copyright © 2023, Author(s).
ABSTRACT
The novel Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is primarily a respiratory virus. However, an increasing number of neurologic complications associated with this virus have been reported, e.g., transverse myelitis (TM). We report a case of a 39-year-old man admitted to Namazi Hospital affiliated with Shiraz University of Medical Sciences, Shiraz, Iran. In December 2020, the patient was infected with Coronavirus Disease 2019 (COVID-19). During hospitalization, the patient suffered from sudden onset of paraplegia, and urinary retention, and had a T6-T7 sensory level. TM was diagnosed and an extensive workup was performed to rule out other etiologies. Eventually, para-infectious TM associated with COVID-19 was concluded. The patient received pulse methylprednisolone therapy of 1 g/day for 10 consecutive days followed by seven sessions of plasma exchange without a favorable response. The patient then underwent regular physical rehabilitation and tapering oral administration of prednisolone 1 mg/Kg. As a result, weakness in the lower extremities improved slightly after six months. Overall, we suspect a correlation between COVID-19 and TM, however, further studies are required to substantiate the association.

BACKGROUND: Transverse myelitis (TM) is characterized by sudden lower extremity progressive weakness and sensory impairment, and most patients have a history of advanced viral infection symptoms. A variety of disorders can cause TM in association with viral or nonviral infection, vascular, neoplasia, collagen vascular, and iatrogenic, such as vaccination. Vaccination has become common through the global implementation against coronavirus disease 2019 (COVID-19) and reported complications like herpes zoster (HZ) activation has increased. CASE SUMMARY: This is a 68-year-old woman who developed multiple pustules and scabs at the T6-T9 dermatome site 1 wk after vaccination with the COVID-19 vaccine (Oxford/AstraZeneca ([ChAdOx1S{recombinant}]). The patient had a paraplegia aggravation 3 wk after HZ symptoms started. Spinal magnetic resonance imaging (MRI) showed transverse myelitis at the T6-T9 Level. Treatment was acyclovir with steroids combined with physical therapy. Her neurological function was slowly restored by Day 17. CONCLUSION: HZ developed after COVID-19 vaccination, which may lead to more severe complications. Therefore, HZ treatment itself should not be delayed. If neurological complications worsen after appropriate management, an immediate diagnostic procedure, such as magnetic resonance imaging and laboratory tests, will start and should treat the neurological complications.
ABSTRACT
We herein report a case of anti-myelin oligodendrocyte glycoprotein (MOG) antibody-related myelitis caused by coronavirus disease (COVID-19) infection in 2021. A 22-year-old man with no history of any related illness contracted COVID-19. Eight days later, he developed bladder problems, paraplegia and sensory disturbances. Cervical spinal cord magnetic resonance imaging revealed extensive hyperintensity at T2 and spinal cord lesions extending from C4 to Th1. The patient was diagnosed with transverse myelitis and started on intravenous methylprednisolone, plasma exchange and intravenous immunoglobulin therapy. The symptoms improved only after intravenous methylprednisolone therapy. Anti-MOG antibodies were found in his serum and cerebrospinal fluid during routine screening. As this observation is unusual and could cause serious health problems, we wonder if COVID-19 triggered this autoimmune response.

BACKGROUND: Various vaccines, tumor-necrosis-factor-alpha inhibitors (TNFAIs), immune-checkpoint inhibitors (ICIs), and other immunomodulators have been linked to inflammatory CNS events. The prevalence of iatrogenic events in the neuroimmunology clinic is unknown. OBJECTIVE: To evaluate the prevalence and clinical characteristics of iatrogenic CNS inflammation in a tertiary neuroimmunology clinic. METHODS: We analyzed 422 consecutive patients seen over five years at a tertiary neuroimmunology clinic who were systematically screened for exposure to vaccines, TNFAIs, ICIs, or other immunomodulators. In patients with suspected iatrogenic events, the Naranjo Adverse Drug Reaction Probability Scale was used to score the probability of iatrogenicity. RESULTS: In total, 27 potential iatrogenic events were observed, accounting for 6.4% of all new referrals. The average Naranjo score was 5.78 +/- 1.65 with 74% of the cases scored as probable and 26% scored as possible. The clinical phenotypes included MS relapses (37%); autoimmune encephalitis (30%); NMOSD attacks (15%); transverse myelitis (11%); optic neuritis (4%); and MOGAD attacks (4%). A monophasic course was observed in 44% of cases while 41% had a relapsing course. All patients stopped or interrupted treatment with the offending agent. In addition, 41% of the iatrogenic events were fully responsive to corticosteroids; 22% were partially responsive; and 15% resolved spontaneously. The most common potential triggers were vaccines (37%) followed by TNFAIs (33%) then ICIs (26%). A significantly higher number of probable iatrogenic events were observed among the ICI and vaccine groups compared to a higher number of possible events among the TNFAI group. The latter group also had a significantly longer interval since exposure. The ICI group was more likely to present with monophasic autoimmune encephalitis. CONCLUSION: Iatrogenic CNS inflammation is rare and typically involves steroid-responsive monophasic events. A subset of iatrogenic events can unmask or worsen relapsing disorders. The probability of iatrogenicity was higher in vaccine and ICI-related events compared to TNFAI-related events.

Case Report: Acute transverse myelitis (TM) is a rare inflammatory disease that typically presents asweakness, sensory alterations, and bowel or bladder dysfunction. Among the causes of TM are infections, paraneoplastic syndromes, or autoimmune conditions of CNS. Postinfectious TM can develop secondary to a viral or bacterial infection. SARS-CoV-2 is a recently discovered viral illness, and sequelae due to COVID-19 infection are still being studied. There is scarce literature relating the two conditions, and it is imperative to raise awareness. A 72-year-old man with hypertension and GERD, completely independent in ADL, was brought to the ED with sudden onset of bilateral lower extremity weakness. He reported symptoms started with difficulty climbing stairs that rapidly progressed to inability to ambulate independently and were associated with bilateral thigh soreness. Nine days prior, he developed fever and generalized malaise, and two days later, SARS-CoV-2 PCR and Ag tests were positive. He received azithromycin, Paxlovid, and dexamethasone as treatment. Upon evaluation, the patient was afebrile and hemodynamically stable. Neurological examination was remarkable for spasticity and hyperreflexia at bilateral lower limbs, clonus, preserved motor strength with adequate sensation to soft touch, and intact vibration and proprioception in all extremities. Cranial nerves were intact. These findings were consistent with an upper motor neuron lesion. On imaging, the Head CT scan was unremarkable. Thoracic/Lumbar Spine MRI was significant for distal thoracic and conus areas with central homogeneous brightness compatible with nonspecific myelitis. Laboratories showed leukocytosis without neutrophilia or bandemia, thrombocytosis, and elevated CRP. HIV and RPR tests were negative. A lumbar puncture for CSF analysiswas remarkable for mild monocytic pleocytosis (7 cell/muL), an increased level of total proteins (56 mg/dL), and normal glucose (57 mg/dL). CSF culture and gram stain were negative. CSF cytology yielded few lymphocytes and few monocytes and was negative for malignant cells. The meningoencephalitis panel was negative. Based on these findings, a clinical diagnosis of postinfectious myelitis secondary to COVID-19was made. The patient was treated with intravenous Methylprednisolone 1 g daily for five days. On follow-up, lower extremity weakness resolved completely, and he resumed his daily physical activities. Patients with COVID-19 infection can present with neurologic manifestations such as headache, myalgias, dizziness, dysgeusia, and anosmia. This case hopes to raise awareness of less commonly known neurological manifestations of SARS-CoV-2 infection and how the early recognition of symptoms can help expedite the diagnosis and treatment of the condition to avoid long-term sequelae.

ABSTRACT
Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), broke out in 2019 and became a pandemic in 2020. Since then, vaccines have been approved to prevent severe illness. However, vaccines are associated with the risk of neurological complications ranging from mild to severe. Severe complications such as vaccine-induced immune thrombotic thrombocytopenia (VITT) associated with acute ischaemic stroke have been reported as rare complications post-COVID-19 vaccination. During the pandemic era, VITT evaluation is needed in cases with a history of vaccination within the last month prior to the event. Cerebral venous sinus thrombosis (CVST) should be suspected in patients following immunization with persistent headaches who are unresponsive to analgesics. In this article, we investigated neurological complications after COVID-19 vaccination and provided more subsequent related clinical studies of accurate diagnosis, pathophysiological mechanisms, incidence, outcome, and management.
ABSTRACT
PURPOSE OF REVIEW: A variety of neurological complications have been reported following the widespread use of the COVID-19 vaccines which may lead to vaccine hesitancy and serve as a major barrier to the public health aim of achieving protective herd immunity by vaccination. In this article, we review the available evidence regarding these neurological adverse events reported, to provide clarity regarding the same so that unfounded fears maybe put to rest. RECENT FINDINGS: There is a greater than expected occurrence of severe neurological adverse events such as cortical sinus venous thrombosis, Bell's palsy, transverse myelitis, and Guillain-Barré syndromes along with other common effects such as headaches following different kinds of COVID-19 vaccination. Precipitation of new onset demyelinating brain lesions with or without detection of specific antibodies and worsening of pre-existing neurological disorders (like epilepsy, multiple sclerosis) are also a matter of great concern though no conclusive evidence implicating the vaccines is available as of now. The COVID-19 pandemic is far from being over. Till such time that a truly effective anti-viral drug is discovered, or an appropriate therapeutic strategy is developed, COVID-appropriate behavior and highly effective mass vaccination remain the only weapons in our armamentarium to fight this deadly disease. As often occurs with most therapeutic means for the treatment and prevention of any disease, vaccination against COVID-19 has its hazards. These range from the most trivial ones like fever, local pain and myalgias to several potentially serious cardiac and neurological complications. The latter group includes conditions like cerebral venous thrombosis (curiously often with thrombocytopenia), transverse myelitis and acute inflammatory demyelinating polyneuropathy amongst others. Fortunately, the number of reported patients with any of these serious complications is far too low for the total number of people vaccinated. Hence, the current evidence suggests that the benefits of vaccination far outweigh the risk of these events in majority of the patients. As of now, available evidence also does not recommend withholding vaccination in patients with pre-existing neurological disorders like epilepsy and MS, though adenoviral vaccines should be avoided in those with history of thrombotic events.
ABSTRACT
BACKGROUND: Transverse myelitis (TM) is a very uncommon condition in children which can be associated with viral infections. Acute TM cases have been reported after Coronavirus disease 2019 (COVID-19) infection during the pandemic. CASE REPORT: We report a child with TM related to severe acute respiratory syndrome coronavirus 2, who was successfully treated with therapeutic plasma exchange (TPE). Inability to walk and urinary retention were the central nervous system symptom. Spinal magnetic resonance imaging revealed signal changes in the spinal cord. Her neurological symptoms worsened despite receiving IVIG and high-dose steroids for the first 3 d. We performed 10 TPE sessions with 5% albumin replacement and the neurological symptoms rapidly improved. CONCLUSION: We demonstrated that a child diagnosed with acute TM related to COVID-19 infection, was successfully treated with TPE.
