Insights

Children with juvenile idiopathic arthritis (JIA) respond well to hepatitis B vaccination, even with immunosuppressive treatment. A 0, 1, and 6-month schedule may offer a better response than a 0, 1, and 3-month schedule.

Area of Science:

  • Immunology
  • Pediatrics
  • Rheumatology

Background:

  • Children with juvenile idiopathic arthritis (JIA) require careful management, including vaccination.
  • Assessing immune response to vaccines in JIA patients is crucial for effective prophylaxis.

Purpose of the Study:

  • To evaluate the hepatitis B vaccine response in children with JIA.
  • To compare two different hepatitis B vaccination schedules (0, 1, 3 months vs. 0, 1, 6 months).
  • To determine if immunosuppressive therapy affects vaccine responsiveness.

Main Methods:

  • 39 children with JIA in remission and 41 healthy controls were enrolled.
  • Two vaccination schedules were used: 0, 1, 3 months (Group I) and 0, 1, 6 months (Group II).
  • Responsiveness was defined as an anti-hepatitis B antibody titre > 10 mIU/ml.

Main Results:

  • All but one JIA patient showed an antibody response; no JIA patients experienced disease flares post-vaccination.
  • Antibody levels in JIA patients were lower than in healthy controls.
  • The 0, 1, 6-month schedule showed a trend towards a greater response in JIA patients (p<0.07), with no difference in controls.
  • Methotrexate or prednisolone treatment did not impact vaccine responsiveness.

Conclusions:

  • Children with JIA demonstrate an adequate response to hepatitis B vaccination.
  • Immunosuppressive treatments did not impede vaccine response in this cohort.
  • A 0, 1, 6-month vaccination schedule appears more beneficial for JIA patients than a 0, 1, 3-month schedule.

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...

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...
Chickenpox01:20

Chickenpox

Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...
Arboviral Encephalitis01:25

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
