What does JIA stand for?
What does JIA stand for?
Juvenile idiopathic arthritis (JIA) is a form of arthritis in children. Arthritis causes joint swelling (inflammation) and joint stiffness. JIA is arthritis that affects one or more joints for at least 6 weeks in a child age 16 or younger.
Does JIA run in families?
Most cases of juvenile idiopathic arthritis are sporadic, which means they occur in people with no history of the disorder in their family. A small percentage of cases of juvenile idiopathic arthritis have been reported to run in families, although the inheritance pattern of the condition is unclear.
What is the Ilar?
The International League of Associations for Rheumatology (ILAR) classification of juvenile idiopathic arthritis (JIA) recognizes 8 categories: systemic arthritis, oligoarthritis, extended oligoarthritis, polyarthritis [rheumatoid factor (RF) positive], polyarthritis (RF negative), enthesitis related arthritis.
How do you calculate Jadas?
The JADAS is calculated as the simple sum of the scores of its four components, which yields a global score of 0–40 for the JADAS10, 0–57 for the JADAS27, and 0–101 for JADAS71. The instrument is feasible and possesses both face and content validity.
What are the three types of JIA?
The three major types include: Oligoarticular JIA (arthritis in four joints or less) Polyarticular JIA (arthritis in five or more joints) Systemic JIA (arthritis plus fever, rash and large lymph nodes)
What is the difference between JIA and JRA?
JIA used to be called juvenile rheumatoid arthritis (JRA), but the name changed because it is not a kid version of the adult disease. The term “juvenile arthritis” is used to describe all the joint conditions that affects kids and teens, including JIA.
Is JIA life threatening?
Rarely, kids with JIA can get a life-threatening problem called macrophage activation syndrome. It happens when the immune system becomes too active and damages some of the body’s organs. It can lead to severe diarrhea, bleeding, hearing loss, confusion, and seizures.
Is JIA serious?
JIA often causes only minor problems, but in some cases it can cause serious joint damage or limit growth. Although JIA mostly affects the joints and surrounding tissues, it can also affect other organs, like the eyes, liver, heart, and lungs. JIA is a chronic condition, meaning it can last for months and years.
What is macrophage activation syndrome?
Macrophage activation syndrome (MAS) is a severe complication of rheumatic disease in childhood, particularly in systemic Juvenile Idiopathic Arthritis (sJIA). It is characterize by an uncontrolled activation and proliferation of T lymphocytes and macrophages.

What is Jadas disease?
Juvenile Arthritis Disease Activity Score (JADAS) is a recently developed composite tool for scoring disease activity in juvenile idiopathic arthritis (JIA).
What is cJADAS10?
Objectives To validate cut-offs of the Juvenile Arthritis Disease Activity Score 10 (JADAS10) and clinical JADAS10 (cJADAS10) and to compare them with other patient cohorts.
