Insights

Cardiovascular risk in HIV patients involves traditional factors and those from HIV infection and its treatment. Increased prevalence of smoking, diabetes, and dyslipidemia necessitates tailored risk assessment and prevention strategies for this growing population.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Public Health

Background:

  • Arteriosclerosis pathogenesis in HIV-infected patients is multifactorial, involving traditional cardiovascular risk factors (CVRF) and those specific to HIV and its treatment.
  • HIV infection is increasingly prevalent in men, with improved life expectancy due to highly-active antiretroviral therapy (HAART).
  • Certain CVRF, including smoking, diabetes mellitus, insulin resistance, dyslipidemia, and hypertriglyceridemia, are more common in HIV-infected individuals.

Purpose of the Study:

  • To investigate the complex interplay of cardiovascular risk factors in HIV-infected patients.
  • To highlight the increased prevalence of traditional CVRF in the HIV-positive population.
  • To emphasize the need for specific cardiovascular risk assessment models for HIV patients.

Main Methods:

  • Review of established cardiovascular risk factors in the general population.
  • Analysis of factors related to highly-active antiretroviral therapy (HAART) and HIV infection.
  • Examination of longitudinal cohort studies on CVRF and cardiovascular disease in HIV-infected individuals.

Main Results:

  • Higher prevalence of smoking (37-72%), diabetes mellitus (17%), insulin resistance (17-51%), dyslipidemia (22-49%), and hypertriglyceridemia (34%) observed in HIV patients.
  • These elevated CVRF are likely linked to lifestyle factors and prolonged exposure to HAART, particularly certain antiretroviral drugs.
  • While overall cardiovascular risk may be low, traditional CVRF gain importance with age in HIV-infected individuals.

Conclusions:

  • Specific mathematical models are needed to accurately calculate individual cardiovascular risk in HIV-infected patients.
  • Tailored cardiovascular prevention strategies are essential for this population.
  • Understanding the unique risk profile is crucial for managing long-term health in aging HIV patients.

Sexually Transmitted Infections01:26

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.

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

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...
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 retrovirus to...

Coronary Artery Disease I: Introduction

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...
