Abstract

Insights

Encephalomyeloradiculopathy (EMR) is a newly identified neurological syndrome. This case study suggests Epstein-Barr virus (EBV) reactivation may play a role in its development, highlighting the need for further research into viral causes of EMR.

Area of Science:

  • Neurology
  • Virology
  • Infectious Diseases

Background:

  • Encephalomyeloradiculopathy (EMR) is a recently described neurological syndrome affecting the brain, medulla, and spinal roots.
  • This report details a patient with a febrile prodrome followed by extensive central and peripheral nervous system involvement, including transverse myelitis, meningitis, encephalitis, and polyradiculopathy.

Observation:

  • The patient presented with a complex neurological illness following a febrile illness.
  • Diagnostic investigations included serological tests, viral cultures, and PCR for viral nucleic acids in serum and cerebrospinal fluid (CSF).

Findings:

  • Cytomegalovirus (CMV) infection was identified, potentially causing the initial febrile illness.
  • Epstein-Barr virus (EBV) DNA was detected in peripheral blood mononuclear cells (PBMCs) and CSF, indicating active infection or reactivation.

Implications:

  • The findings suggest a potential role for EBV in the pathogenesis of EMR, a syndrome with severe neurological sequelae.
  • Further investigation into viral triggers for EMR is warranted to improve diagnosis and treatment strategies.

Diphtheria

Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
