Insights

Progressive multifocal leukoencephalopathy (PML), a brain infection, was diagnosed in an immunocompromised patient with alcoholic liver dysfunction. This case highlights PML as a rare complication in patients with liver disease.

Area of Science:

  • Neuroscience
  • Infectious Diseases
  • Hepatology

Background:

  • Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the central nervous system caused by JC virus.
  • PML typically affects immunosuppressed individuals, increasing its incidence in patients with conditions like acquired immunodeficiency syndrome (AIDS).

Observation:

  • A 59-year-old man with a history of alcoholic liver dysfunction presented with progressive left leg weakness.
  • MRI revealed multiple white matter lesions characteristic of PML, including T1 low and T2 high intensities.
  • Biopsy confirmed demyelination and oligodendroglial nuclear enlargement, with electron microscopy showing JC virus particles.

Findings:

  • JC virus infection in the central nervous system was confirmed via polymerase chain reaction (PCR) on cerebrospinal fluid.
  • Histopathology and viral particle identification confirmed PML diagnosis.
  • The patient's immune-compromised state was linked to alcoholic liver dysfunction.

Implications:

  • This case represents the first documented instance of PML in an immunocompromised individual with alcoholic liver dysfunction.
  • Highlights the importance of considering PML in immunocompromised patients presenting with neurological deficits, even with underlying liver disease.
  • Suggests alcoholic liver dysfunction can contribute to an immunocompromised state susceptible to opportunistic infections like PML.

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...

Alzheimer Disease l: Introduction

Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...

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...

Alzheimer Disease ll: Pathophysiology

Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...

Dementia l: Introduction

Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
