Insights

Hepatitis C virus (HCV) infection is more prevalent in patients with systemic lupus erythematosus (SLE) than in the general population. Testing for HCV is recommended when SLE is suspected.

Area of Science:

  • Immunology
  • Hepatology
  • Rheumatology

Background:

  • Hepatitis C virus (HCV) infection is linked to autoimmune conditions.
  • HCV can present with symptoms mimicking systemic lupus erythematosus (SLE).
  • Limited data exists on HCV prevalence in SLE patients.

Purpose of the Study:

  • To determine the prevalence of HCV viremia in SLE patients.
  • To compare HCV prevalence in SLE patients to control groups.

Main Methods:

  • Sera from 40 SLE patients (1993-2000) were tested for HCV viral load using PCR.
  • HCV prevalence was compared to local blood donors and the US general population.

Main Results:

  • HCV was detected in 10% (4/40) of SLE patients.
  • HCV prevalence in SLE patients was significantly higher than in local blood donors (0.13%) and the US general population (1.33%).

Conclusions:

  • Findings support an increased prevalence of HCV infection in SLE patients.
  • Further research into the association may elucidate SLE pathogenesis.
  • HCV screening is advised when considering an SLE diagnosis.

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...

Diseases of the Liver and Gallbladder

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...

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...

Effect of Hepatic Disease on Pharmacokinetics: Active Drug, Metabolite and Fraction of Metabolized Drug

In pharmacotherapy, monitoring drug concentrations is paramount, especially for drugs whose therapeutic effects hinge on both the active compound and its metabolite. Hepatic impairment profoundly influences drug potency by altering liver function. If the drug is more potent than its metabolite, impaired liver function amplifies drug activity due to elevated drug concentration levels. Conversely, if the metabolite holds greater potency, diminished liver function diminishes drug activity by...
