Symptoms Of Juvenile Idiopathic Arthritis: Causes & Treatment

Juvenile idiopathic arthritis is one of the most common forms of arthritis in children and adolescents. The disease is spread across the world. Juvenile idiopathic arthritis causes chronic pain, stiffness and swelling of joint. The disease was formerly called juvenile rheumatoid arthritis or juvenile chronic arthritis. However it was renamed as juvenile idiopathic arthritis. Since there is no identifiable etiology of the condition it is called idiopathic. The symptoms in children may last for few months or may remain permanently.

The disease is classified into six sub-types. Each sub-type has its own criteria of diagnosis.

However, the hallmark of disease remains same; inflammation of joints, accumulation of fluid in the tissue and thickening of synovial membrane. Arthritis can develop in any joint but most often large joints are affected. Certain types of juvenile arthritis can lead to serious health issue that includes inflammation of eye and even growth retardation of the child. The aim of treatment is to alleviate and control acute symptoms and prevent complications.

What Causes Juvenile Idiopathic Arthritis?

There is no known cause yet determined for juvenile idiopathic arthritis. Researchers are not able to pinpoint towards any evidence that may suggest toxins and allergies in children as the cause for development of the disease.

 It is believed to develop due to autoimmune cause. Meaning the body’s own immune system goes haywire and starts attacking its cells and tissues.

The exact cause for this occurrence is not known, but it is believed to have an association with environment and hereditary.  Genetic predisposition is believed to make the person susceptible to arthritis when certain external factors act as a trigger, for example virus infection. There is no specific risk factor, but some forms of juvenile idiopathic arthritis is seen more often in girls.
