Insights

Subacute central nervous system infections, like HIV encephalopathy, can cause progressive developmental delays in infants. Early diagnosis and antiretroviral treatment are crucial for improving neurological outcomes in affected children.

Area of Science:

  • Pediatrics
  • Neurology
  • Infectious Diseases

Background:

  • Subacute central nervous system (CNS) infections require consideration in infants with progressive encephalopathy.
  • Maternal HIV infection poses a risk for vertical transmission to the infant, potentially leading to neurological complications.

Observation:

  • An 18-month-old child presented with spastic hypertonia and axial hypotonia after normal early development.
  • The child's mother was diagnosed with HIV, and the infant tested positive for HIV with a decreased CD4 cell count and detectable viral load.
  • Brain MRI revealed white matter hypersignals, indicative of CNS involvement.

Findings:

  • The infant was diagnosed with HIV-related encephalopathy, presumed to be due to maternal-fetal transmission.
  • Antiretroviral therapy, including azidothymidine, lamivudine, and boosted lopinavir, was initiated.
  • Neurological symptoms showed improvement after two months of treatment.

Implications:

  • HIV infection should be suspected in infants presenting with progressive encephalopathy.
  • Routine HIV testing for pregnant women, including repeat testing in the third trimester, is recommended to prevent vertical transmission.
  • Timely diagnosis and initiation of antiretroviral therapy can significantly improve neurological outcomes in pediatric HIV encephalopathy.

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...
Hepatic Encephalopathy01:29

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...
Encephalitis ll: Pathophysiology01:26

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...
Arboviral Encephalitis01:25

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...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
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...
