Insights

Hepatitis C virus (HCV) coinfection negatively impacts CD4 cell counts in human immunodeficiency virus (HIV)-infected adults with alcohol problems who adhere to antiretroviral therapy (ART). Addressing HCV may improve immune function in this population.

Area of Science:

  • Infectious Diseases
  • Hepatology
  • Immunology

Background:

  • Coinfection with HIV and HCV presents significant challenges in patient management and public health.
  • Alcohol consumption can exacerbate HCV liver disease and hinder adherence to HIV treatment.
  • Understanding the interplay between alcohol, HCV, and HIV progression is crucial.

Purpose of the Study:

  • To investigate the association between HCV infection and markers of HIV disease progression.
  • To examine how HCV coinfection affects CD4 cell counts and HIV RNA levels in adults with alcohol problems.
  • To assess the impact of adherence to antiretroviral therapy (ART) on these associations.

Main Methods:

  • A longitudinal study involving 396 HIV-infected adults with alcohol problems.
  • Categorization based on HCV coinfection status (HCV RNA positive).
  • Regular assessment of CD4 cell counts and HIV RNA levels over up to 42 months, analyzed using multivariable regression models.

Main Results:

  • HCV coinfection was linked to a significantly lower CD4 cell count (-46.0 cells/microL) among patients adherent to ART (p=0.03).
  • No significant association between HCV infection and CD4 cell count was found in patients not adherent to or not on ART.
  • No significant association was observed between HCV infection and HIV RNA levels, irrespective of ART status.

Conclusions:

  • HCV coinfection adversely affects CD4 cell counts in HIV-infected individuals with alcohol problems who are adherent to ART.
  • Treating HCV coinfection in this population may lead to improved immunological outcomes.
  • Targeting HCV in coinfected patients on ART could enhance immune reconstitution.

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: Introduction01:28

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...
Pulmonary Tuberculosis I01:29

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.

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...
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...

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...
