Study Notes
Overview of Rheumatoid Arthritis
- Chronic systemic autoimmune disorder affecting connective tissue.
- Causes symmetrical inflammation of synovial tissue in joints.
- Characterized by destruction and proliferation of the synovial membrane, leading to joint destruction, ankylosis, and deformity.
Normal Joint vs. Rheumatoid Arthritis
- Normal joint: Includes a healthy synovial membrane, synovial fluid, and cartilage.
- Rheumatoid Arthritis: Exhibits bone erosion and swollen, inflamed synovial membranes.
Autoimmune Nature
- Immune system mistakenly attacks the body's own tissues.
- Can affect joints and other organs such as skin, eyes, lungs, and blood vessels.
Etiology and Risk Factors
- Exact cause remains unknown; initial autoimmune response affects the synovial membrane.
- Potential triggers may include infections, genetic predispositions, and hormonal changes.
Genetic Factors
- Certain genes associated with the immune system may influence the likelihood of developing RA.
Other Risk Factors
- Sex: Higher prevalence in women compared to men.
- Age: Most commonly onset between ages 30 and 60.
- Family History: Increased risk if there is a family history of RA.
- Hormonal Factors: Changes or deficiencies in hormones may contribute.
- Smoking: Long-term smoking identified as a significant risk factor.
- Infections: Exposure to certain pathogens like Epstein-Barr virus may be linked to initiation of RA.
- Immunological Response: Abnormal immune responses can play a role.
- Metabolic and Biochemical Abnormalities: These may also factor into the development of RA.
Stages of Rheumatoid Arthritis
- Synovitis: Initial stage where involved joints develop localized inflammation in the joint capsule, potentially causing excess synovial fluid production.
