Insights

Cumulative damage is common in Arab children with juvenile idiopathic arthritis (JIA). Family history and longer disease duration are associated with increased joint and extraarticular damage in JIA patients.

Area of Science:

  • Pediatric Rheumatology
  • Autoimmune Diseases
  • Clinical Immunology

Background:

  • Juvenile idiopathic arthritis (JIA) is a chronic autoimmune condition affecting children.
  • Understanding cumulative disease damage is crucial for managing JIA progression.
  • Limited data exists on JIA-related damage in Arab populations.

Purpose of the Study:

  • To assess cumulative articular and extraarticular damage in Arab children with JIA.
  • To identify factors associated with disease damage in this cohort.

Main Methods:

  • Multicenter, cross-sectional study across 7 Arab countries.
  • Included 702 JIA patients meeting ILAR criteria with >1 year disease duration.
  • Assessed damage using Juvenile Arthritis Damage Index (JADI-A and JADI-E).

Main Results:

  • 193 patients had joint damage (mean JADI-A 1.7±4.5), 156 had extraarticular damage (mean JADI-E 0.5±1.1).
  • Enthesitis-related arthritis showed highest JADI-A. JADI-A correlated with family history.
  • Both JADI-A and JADI-E correlated with longer disease duration.

Conclusions:

  • Cumulative damage is prevalent in Arab JIA patients.
  • Consanguinity and having a sibling with JIA were associated with greater damage.
  • Family history and disease duration are key factors in JIA damage.

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
