Insights

Children with chronic viral hepatitis show an impaired antioxidant defense. Key enzymes like catalase (CAT) and superoxide dismutase (SOD) were decreased, while glutathione peroxidase (GSH-Px) increased, suggesting a weakened antioxidant barrier.

Area of Science:

  • Pediatric Hepatology
  • Biochemistry
  • Immunology

Background:

  • Chronic viral hepatitis (Hepatitis B and C) is a significant health concern in children.
  • Oxidative stress plays a role in the pathogenesis of chronic liver diseases.

Purpose of the Study:

  • To evaluate the antioxidant defense status in children diagnosed with chronic viral hepatitis.
  • To assess the activity of key antioxidant enzymes in pediatric patients with HBV or HCV infection.

Main Methods:

  • Study included 100 children with confirmed HBV or HCV infection.
  • Assayed erythrocyte activity of catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px).

Main Results:

  • A statistically significant reduction in CAT and SOD activities was observed.
  • An increase in GSH-Px activity was noted in children with chronic hepatitis B and C.
  • These findings indicate an altered antioxidant enzyme profile.

Conclusions:

  • Children with chronic viral hepatitis may experience insufficiency of their antioxidant barrier.
  • Further research is warranted to explore therapeutic strategies targeting oxidative stress in pediatric viral hepatitis.

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...

Vitamins

Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...
Cytomegalovirus Disease01:27

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...
Hepatitis01:25

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...

Antiviral Nucleoside Inhibitors

Antiviral Nucleoside InhibitorsAntiviral nucleoside inhibitors are structural analogs of natural nucleosides that interfere with viral DNA or RNA synthesis. These compounds selectively target viral polymerases due to their resemblance to host nucleosides, thereby disrupting viral genome replication.Mechanism of Acyclovir ActionAcyclovir is a guanosine analog with a three-carbon acyclic side chain. It selectively targets herpes simplex virus type 1 (HSV-1), herpes simplex virus type 2 (HSV-2),...
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...
