Insights

People living with HIV face higher risks of cardiovascular disease due to persistent inflammation, even with treatment. Research explores these inflammation-driven mechanisms and potential anti-inflammatory therapies for heart health.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Immunology

Background:

  • Cardiovascular disease (CVD) is a major cause of death in people with HIV.
  • HIV-infected individuals have a higher risk of myocardial infarction and stroke than uninfected individuals.
  • While traditional risk factors play a role, HIV-specific factors, particularly systemic inflammation, contribute to increased CVD risk.

Purpose of the Study:

  • To review the evidence linking inflammation and CVD in people living with HIV.
  • To discuss the multifactorial causes of sustained immune activation despite antiretroviral therapy.
  • To explore potential anti-inflammatory treatment strategies for cardiometabolic disease in this population.

Main Methods:

  • Literature review of epidemiological studies and immunological research.
  • Analysis of the relationship between inflammatory markers and CVD incidence.
  • Synthesis of current understanding of HIV-related inflammation.

Main Results:

  • Elevated inflammatory markers persist in people with HIV, even with effective antiretroviral therapy.
  • Systemic inflammation is a significant contributor to the heightened CVD risk in this population.
  • The precise mechanisms driving sustained inflammation in HIV are complex and not fully elucidated.

Conclusions:

  • Inflammation plays a critical role in the elevated cardiovascular disease burden among people living with HIV.
  • Further research into the causes of persistent inflammation is needed.
  • Targeting inflammation may offer promising therapeutic avenues for preventing and treating cardiometabolic disease in people with HIV.

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

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...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...
