Insights

Human Immunodeficiency Virus (HIV) infection is now a chronic condition. However, HIV and its treatments increase the risk of serious blood clots and cardiovascular issues.

Area of Science:

  • Cardiovascular Science
  • Infectious Diseases
  • Hematology

Background:

  • Human Immunodeficiency Virus (HIV) infection has transitioned into a chronic disease due to antiretroviral therapy (ART).
  • While ART improves longevity and quality of life, it contributes to new complications, notably thromboembolic events.
  • HIV-associated chronic inflammation, endothelial dysfunction, and ART-induced metabolic changes create a prothrombotic state.

Purpose of the Study:

  • To review the multifactorial mechanisms underlying the increased thrombotic risk in HIV-infected individuals.
  • To highlight the heightened risk of venous thromboembolism and cardiovascular disease in the HIV population.
  • To discuss specific ART-related risks, other coagulation disorders, and therapeutic considerations in HIV patients.

Main Methods:

  • Literature review of studies on HIV, thromboembolism, and cardiovascular disease.
  • Analysis of pathophysiological mechanisms including inflammation, endothelial dysfunction, and ART effects.
  • Examination of co-infection and gut microbiome influences on the prothrombotic microenvironment.

Main Results:

  • Individuals with HIV face a significantly higher risk of venous thromboembolism and cardiovascular disease compared to the general population.
  • Certain ART regimens are associated with an increased risk of myocardial infarction in HIV patients.
  • HIV infection is linked to other coagulation disorders like heparin-induced thrombocytopenia and thrombotic thrombocytopenic purpura.

Conclusions:

  • HIV infection and its management, particularly ART, contribute to a prothrombotic state and increased cardiovascular risk.
  • Careful consideration of drug interactions is necessary when managing coagulation disorders in HIV patients.
  • Further research is essential to elucidate underlying mechanisms and develop targeted treatments for thrombotic complications in HIV.

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
