-Systemic Juvenile Idiopathic Arthritis

-Oligoarticular juvenile idiopathic arthritis

-Polyarticular juvenile idiopathic arthritis

-Polyarticular juvenile idiopathic arthritis

-Psoriatic juvenile idiopathic arthritis.

What Causes Juvenile Arthritis?

The cause of Juvenile Arthritis is not yet known. It’s like when you have ants coming into your house, you can’t stop them coming in until you find the source of where they’re coming from in the first place. This is like JuKAWarriorsvenile Arthritis, once we can find the source we may just find the cure.

Most Juvenile Arthritis’ are autoimmune disorders with mean that the child’s immune system which would normally help fight off bad bacteria or viruses, mistakenly attacks some of the child’s healthy tissues and cells. This results in inflammation which is marked by redness, pain, swelling and heat. This can cause joint damage and the doctors are still unsure why this happens. They do how ever suspect that it’s a two step process. Firstly where something in the genetic makeup gives the child a tendency to develop JIA, but then there’s environmental factors such as viruses that may trigger the development of the disease, but medical professional are still unsure.

Not all Juvenile Arthritis cases are autoimmune, but recent research demonstrated that some children like those with Systemic Arthritis. Have what’s more accurately known as an auto inflammatory condition. Although the term sounds similar to the one mentioned above, they’re both quite different.

When a child’s immune system is in proper working order, foreign bacteria and viruses provoke the body to make proteins that we call antibodies. These attach themselves to the invaders so that they can be recognised and destroyed. Tn an autoimmune reaction the antibodies attach to the child’s healthy tissue by mistake, which then signals their bodies to attack them. Due to them targeting themselves they are called auto bodies.

Just like autoimmune disorders, these auto inflammatory conditions also causes inflammation and like autoimmune disorders they as well involve an overactive immune system. This auto inflammation isn’t caused by auto antibodies, instead auto inflammation involves a more primitive part of the immune system that in healthy children causes while blood cells to destroy any harmful substances. When this bodily system goes awry it causes inflammation for many unknown reasons and it also can cause fever and rashes.
