PURPOSE OF REVIEW: This article reviews bacterial, viral, fungal, and parasitic pathogens associated with myelopathy. Infectious myelopathies may be due to direct infection or parainfectious autoimmune-mediated mechanisms; this article focuses primarily on the former. RECENT FINDINGS: Some microorganisms exhibit neurotropism for the spinal cord (eg, enteroviruses such as poliovirus and flaviviruses such as West Nile virus), while others are more protean in neurologic manifestations (eg, herpesviruses such as varicella-zoster virus), and others are only rarely reported to cause myelopathy (eg, certain fungal and parasitic infections)...

PURPOSE: The purposes of this article were to evaluate the short-term outcome of plasma exchange (PLEX) for neuromyelitis optica spectrum disorders (NMOSDs) in Chinese patients and to identify the factors predictive of a favorable response to therapy. METHODS: We retrospectively analyzed data from 29 Chinese patients with NMOSD. All patients received 2 to 7 sessions of PLEX every other day. Expanded Disability Status Scale (EDSS) scores were estimated at baseline, at relapse, and before and at follow-up after PLEX...

The epidemiology of spinal cord disease in human immunodeficiency virus (HIV) infection is largely unknown due to a paucity of data since combination antiretroviral therapy (cART). HIV mediates spinal cord injury indirectly, by immune modulation, degeneration, or associated infections and neoplasms. The pathologies vary and range from cytotoxic necrosis to demyelination and vasculitis. Control of HIV determines the differential for all neurologic presentations in infected individuals. Primary HIV-associated acute transverse myelitis, an acute inflammatory condition with pathologic similarities to HIV encephalitis, arises in early infection and at seroconversion...

Enterovirus D68 (EV-D68) is a medically important respiratory plus-strand RNA virus of children that has been linked to acute flaccid myelitis. We have determined that EV-D68 induces autophagic signaling and membrane formation. Autophagy, a homeostatic degradative process that breaks down protein aggregates and damaged organelles, promotes replication of multiple plus-strand viruses. Induction of autophagic signals promotes EV-D68 replication, but the virus inhibits the downstream degradative steps of autophagy in multiple ways...

RATIONALE: Spinal cord infarction is one of the complications of epidural steroid injections (ESIs), but has only been reported in cervical vertebra by transforaminal injection and lumbar vertebra by transforaminal injection; and up to now, there is no reporting about spinal cord infarction caused by caudal injection. Here, we report a case. PATIENT CONCERNS: A 52-year-old man was admitted to our hospital. He was diagnosed as lumbar disc herniation in other hospital, and the patient suffered bilateral lower limb motor and sensory disorders after administration of caudal ESI...

RATIONALE: Neuromyelitis optica spectrum disorders (NMOSDs) represent recurrent autoimmune diseases, generally beginning with optic nerve neuritis or acute transverse myelitis. PATIENT CONCERNS: A 57-year-old male with long-term alcohol intake was hospitalized because of limb numbness. EMG examination showed the peripheral sensory nerve was in demyelination and an axonal injury was found. His symptoms could not be improved by vitamin B injection but were later significantly attenuated by dexamethasone treatment...

Increased circulation of enterovirus D68 in 2014 and 2016 temporally and geographically coincided with increases in cases of acute flaccid myelitis, an uncommon condition of paralysis due to lesions in the anterior horn of the spinal cord. The identification of enterovirus D68 in respiratory specimens from cases of acute flaccid myelitis worldwide further supports an association, yet the absence of direct virus isolation from affected tissues, infrequent detection in cerebrospinal fluid, and the absence, until recently, of an animal model has left the causal nature of the relationship unproven...

Zika virus (ZIKV) has received widespread attention because of its effect on the developing fetus. It is becoming apparent, however, that severe neurological sequelae, such as Guillian-Barrë syndrome (GBS), myelitis, encephalitis, and seizures can occur after infection of adults. This study demonstrates that a contemporary strain of ZIKV can widely infect astrocytes and neurons in the brain and spinal cord of adult, interferon α/β receptor knockout mice (AG129 strain) and cause progressive hindlimb paralysis, as well as severe seizure-like activity during the acute phase of disease...

Objective: To identify genetic differences among siblings with a family history of idiopathic transverse myelitis (ITM). Methods: We compared whole-exome sequencing (WES) on germline samples from the 2 affected sisters with ITM with 3 of their healthy siblings. Results: The 2 sisters with ITM both had acute onset of sensory loss in the legs, weakness, and bowel/bladder dysfunction. The first developed ITM at age 15 years with a clinical nadir of complete paralysis, which slowly recovered over a few years...

Spinal cord infarction (SCI) is a rare type of stroke. The initial magnetic resonance imaging (MRI) is usually normal and can mimic the presentation of the acute transverse myelitis (ATM), acute inflammatory demyelinating polyneuropathy, and compressive myelopathies from neoplasm, epidural or subdural hematoma, or abscess. The aim of this report is to describe and discuss the case of a patient with SCI presenting as a diagnostic confusion with acute transverse myelitis. A 64-year-old male with a medical history of hypertension presented with an acute onset of urinary retention with lower limb weakness...

Glial fibrillary acidic protein antibody-positive meningoencephalomyelitis is a newly described, possibly under-recognised, severe inflammatory condition of the nervous system. The clinical presentation is variable but most commonly is a combination of meningitis, encephalitis and myelitis; other manifestations may include seizures, psychiatric symptoms and tremor. There is a significant association with malignancies, often occult, and with other autoimmune conditions. Although the disease responds well to corticosteroids acutely, it typically relapses when these are tapered, and so patients need long-term immunosuppression...

Neuromyelitis optica spectrum disorders (NMOSDs) are a set of demyelinating disorders that primarily target the optic nerves and the spinal cord. Previously thought to be a subset of multiple sclerosis (MS), now is recognized as a distinct entity. We present a 59-year-old female patient who was admitted for acute upper and lower extremity weakness. The patient had woken up from sleep with sudden onset of weakness. Patient was initially diagnosed with a right hemispheric stroke; however, magnetic resonance imaging of the cervical spine later performed showed abnormal enhancement from C2-C4, representing transverse myelitis...

Recent studies revealed an association between Zika virus infection and a variety of neurological disorders, including microcephaly, meningoencephalitis, myelitis, and Guillain-Barré syndrome (GBS). Following the first report of a patient diagnosed with GBS after Zika virus infection in December 2013, the number of GBS patients significantly increased in endemic countries, such as French-Polynesia and Latin American countries. Electrophysiological studies suggested that patients suffering from GBS associated with Zika virus infection manifest acute inflammatory demyelinating polyneuropathy (AIDP), rather than acute motor axonal neuropathy (AMAN)...

Acute flaccid myelitis (AFM) is a newly defined, rare, but clinically distinct syndrome of acute flaccid paralysis with spinal motor neuron involvement of unknown etiology. Clusters of AFM coincided with a nationwide outbreak of enterovirus D68 (EV-D68) in the United States during autumn to winter of 2014 and in Japan during the autumn of 2015. Although EV-D68 was detected in only 20% of the AFM patients, mainly from respiratory specimens without apparent viral detection from blood and cerebrospinal fluid (CSF) samples, strong temporal associations were noted...

BACKGROUND: During 2015-16 Brazil experienced the largest epidemic of Zika virus ever reported. This arthropod-borne virus (arbovirus) has been linked to Guillain-Barré syndrome (GBS) in adults but other neurological associations are uncertain. Chikungunya virus has caused outbreaks in Brazil since 2014 but associated neurological disease has rarely been reported here. We investigated adults with acute neurological disorders for Zika, chikungunya and dengue, another arbovirus circulating in Brazil...

Human herpes virus 7 (HHV-7) is a cause of encephalitis, meningitis and myeloradiculoneuropathy in adults who are immunocompetent or with immunosuppression. The involvement of the peripheral nervous system is always associated with myelitis. We report a case of acute polyradiculoneuropathy due to HHV-7, without involvement of central nervous system, in an immunocompetent patient. A 35-years-old man complained of lumbar pain radiating to both buttocks. On examination muscle strength and tendon reflexes were normal...

Antibodies against the myelin oligodendrocyte glycoprotein (MOG-Ab) can be detected in various pediatric acquired demyelinating syndromes (ADS). Here, we analyze the spectrum of neuroradiologic findings in children with MOG-Ab and a first demyelinating event. The cerebral and spinal MRI of 69 children with different ADS was assessed in regard to the distribution and characteristics of lesions. Children with acute disseminated encephalomyelitis (n = 36) or neuromyelitis optica spectrum disorder (n = 5) presented an imaging pattern characterized predominantly by poorly demarcated lesions with a wide supra- and infratentorial distribution...

Cytomegalovirus can cause severe disease in immunocompromised patients including encephalomyelitis, hepatitis, pneumonitis, colitis and retinitis. CMV induced myelitis and hepatitis are rare in immunocompetent patients. Following a thorough search on the literature using pubmed, there were only 10 well documented CMV-induced transverse myelitis cases reported worldwide. We report a healthy young male who developed longitudinal extensive transverse myelitis and acute hepatitis secondary to CMV infection. Our case is different from the other cases as our patient had concurrent acute hepatitis and received plasma exchange therapy (PLEX) in addition to pulsed steroids and antivirals...
