Insights

Hepatitis C co-infection significantly increases the odds of cardiovascular disease (CVD) in individuals with HIV. This highlights the importance of managing hepatitis C to reduce CVD risk in this population.

Area of Science:

  • Infectious Diseases
  • Cardiology
  • Epidemiology

Background:

  • Cardiovascular disease (CVD) is a leading cause of morbidity and mortality in individuals with HIV.
  • Hepatitis C virus (HCV) infection is common among HIV-infected individuals and may influence CVD risk.

Purpose of the Study:

  • To investigate the association between hepatitis C co-infection and the prevalence of cardiovascular disease (CVD) in a cohort of HIV-infected individuals.

Main Methods:

  • Cross-sectional analysis of data from the HIV-Longitudinal Interrelationships of Viruses and Ethanol (HIV-LIVE) cohort.
  • Logistic regression was used to compare CVD prevalence between HIV-infected individuals with and without hepatitis C co-infection.

Main Results:

  • The prevalence of CVD was substantially higher in individuals co-infected with HIV and hepatitis C (11.1%) compared to those with HIV alone (2.5%).
  • Hepatitis C co-infection was associated with significantly higher age-adjusted odds of CVD (adjusted OR 4.65).
  • This association remained robust after adjusting for various sociodemographic, substance use, and cardiovascular risk factors.

Conclusions:

  • Hepatitis C co-infection is linked to increased odds of prevalent CVD among HIV-infected individuals.
  • These findings suggest that hepatitis C may contribute to an elevated risk of cardiovascular disease in the context of HIV infection.

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...

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...
Cirrhosis II: Pathophysiology01:24

Cirrhosis II: Pathophysiology

Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
