Study Notes
Common Types of Arthritis and Autoimmune Diseases
- Osteoarthritis is the most common arthropathy affecting 10-13% of the US population, with knee and hip joints being most commonly affected.
- Risk factors for osteoarthritis include obesity, autoimmune diseases, increased age, previous joint injury, and repetitive motion.
- Rheumatoid arthritis is an autoimmune disease that affects 1-2% of the adult population, with a higher prevalence in women and an average onset between 20-30 years.
- Rheumatoid arthritis is characterized by autoimmune destruction of the joints, leading to joint deformity and reduced life expectancy.
- Diagnosis of rheumatoid arthritis involves lab tests for rheumatoid factor, anti-cyclic citrullinated peptide antibody, antinuclear antibody, and HLA-DR1 and HLA-DR4.
- Treatment for rheumatoid arthritis includes disease-modifying anti-rheumatic drugs, biologics, anti-inflammatories, physical therapy, exercise, and surgery.
- Juvenile idiopathic arthritis is the most common childhood arthritis, affecting approximately 1 in 1000 children, with onset before 16 years and a higher prevalence in females.
- Symptoms of juvenile idiopathic arthritis include joint stiffness, limited range of motion, systemic symptoms, and ocular manifestations such as anterior uveitis.
- Gout is characterized by acute episodes of painful joint inflammation caused by uric acid buildup, affecting 3 million cases in the US, with a higher prevalence in men and in African Americans.
- Risk factors for gout include age, sex, genetics, renal disease, diet, obesity, and systemic diseases such as hypertension, diabetes, and hyperlipidemia.
- Diagnosis of gout involves serology, urinalysis, and synovial fluid aspiration, and treatment aims to reduce pain, inflammation, and uric acid levels through medication and dietary modifications.
- Reactive arthritis, also known as Reiter's syndrome, is an inflammatory arthritis occurring after genitourinary or gastrointestinal infection, with a higher prevalence in men and a classic triad of symptoms involving the eyes, urinary system, and joints.
