Insights

Highly active antiretroviral therapy (HAART) in HIV patients increases the risk of premature cerebrovascular disease due to metabolic changes and aging. Long-term vascular prevention strategies are crucial for this growing population.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Cardiovascular Science

Background:

  • Cerebrovascular disease (CVD) is a known complication in HIV-infected individuals.
  • HIV patients on highly active antiretroviral therapy (HAART) experience increased longevity but face unique vascular risks.
  • These risks stem from HAART-induced metabolic disorders and the natural aging process, leading to premature cerebral arteriopathy.

Purpose of the Study:

  • To investigate the association between HAART, metabolic changes, aging, and cerebrovascular disease in HIV patients.
  • To highlight the emergence of premature atherosclerotic cerebral arteriopathy in this cohort.
  • To emphasize the need for long-term vascular prevention strategies.

Main Methods:

  • Review of existing studies documenting subclinical atherosclerosis in HIV patients on HAART.
  • Assessment of vascular changes using intima-media thickness measurements.
  • Ultrasound detection of carotid artery plaques and intracerebral small-vessel disease.

Main Results:

  • Subclinical cervical artery atherosclerosis is prevalent in HIV patients on HAART.
  • Intima-media thickness and carotid artery plaques correlate with HAART-induced metabolic changes.
  • Intracerebral small-vessel disease is also associated with these metabolic alterations.

Conclusions:

  • HIV patients on HAART are at increased risk for premature cerebrovascular disease.
  • Metabolic changes induced by HAART, combined with aging, contribute significantly to this risk.
  • Long-term, proactive vascular prevention is essential for managing HIV-associated cerebrovascular complications.

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Hemorrhagic Stroke ll: Pathophysiology01:29

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
Ischemic Stroke ll: Pathophysiology01:15

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
Dementia l: Introduction01:22

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...
