Final answer:
Juvenile Idiopathic Arthritis (JIA) and adult Rheumatoid Arthritis (RA) differ in affected demographic, pattern of joint involvement, systemic features, and prognosis. RA occurs typically in adults aged 40-50 and is diagnosed through imaging and blood tests, while JIA affects children and considers growth in treatment.
Step-by-step explanation:
The main differences between Juvenile Idiopathic Arthritis (JIA) and adult Rheumatoid Arthritis (RA) lie in the demographic affected, the pattern of joint involvement, systemic features, and the prognosis of the condition. While RA usually presents in adults between the ages of 40 and 50 and is more common in women, JIA occurs in children under the age of 16 and can affect both genders.
JIA is characterized by different types, with varying symptoms and prognoses, while adult RA commonly features symmetrical joint involvement, chronic inflammation, and potential for significant joint damage over time. Diagnosis methods such as X-rays, MRI, blood tests for rheumatoid factor (RF), anti-CCP, and inflammation markers like C-reactive protein (CRP) are common for RA.
Treatment for both conditions includes anti-inflammatory medications, disease-modifying anti-rheumatic drugs (DMARDs), and physical therapy, with considerations for growth and development in children with JIA.
