Rheumatoid Arthritis (RA)
What is Rheumatoid Arthritis?
Rheumatoid Arthritis (RA) is a chronic autoimmune disorder where the body's immune system attacks the synovium – the lining of the joints. This causes persistent inflammation, pain, swelling, and over time can lead to joint deformity and systemic complications.
Causes and Risk Factors
- Autoimmune Dysfunction: Immune cells attack synovial tissue, producing inflammatory cytokines.
- Genetic Predisposition: HLA-DR4 gene is strongly associated with RA risk.
- Environmental Factors: Smoking, infections, and exposure to silica increase risk.
- Hormonal Influences: Women are more susceptible, especially in reproductive age.
Symptoms of RA
- Joint pain, swelling, and warmth (commonly small joints of hands and feet)
- Morning stiffness lasting >1 hour
- Symmetrical joint involvement
- Fatigue and generalized weakness
- Occasional low-grade fever
- Joint deformities in chronic RA
Multisystem Complications
| System | Possible Complications |
|---|---|
| Musculoskeletal | Joint deformity, tendon rupture, osteoporosis |
| Cardiovascular | Pericarditis, increased risk of myocardial infarction |
| Respiratory | Interstitial lung disease, pleuritis |
| Hematologic | Anemia of chronic disease, thrombocytosis |
| Skin | Rheumatoid nodules, vasculitis |
| Ocular | Scleritis, keratoconjunctivitis sicca (dry eyes) |
Diagnosis
- Blood tests: Rheumatoid Factor (RF), Anti-CCP antibodies, ESR, CRP
- Imaging: X-ray, MRI, or Ultrasound to detect joint erosion
- Clinical criteria: American College of Rheumatology (ACR) classification
Management
RA treatment combines medications, lifestyle adjustments, and multidisciplinary care:
- Medications: NSAIDs, corticosteroids, DMARDs (Methotrexate, Hydroxychloroquine), biologics (TNF inhibitors, IL-6 inhibitors)
- Physical Therapy: Maintains joint mobility and muscle strength
- Occupational Therapy: Joint protection, ergonomic adaptations
- Regular Monitoring: Blood tests, organ function, and disease activity assessment
Preventive Lifestyle and Daily Tips
- Exercise Regularly: Low-impact aerobic exercises, stretching, and strength training
- Balanced Anti-inflammatory Diet: Omega-3 fatty acids (salmon, chia), leafy greens, berries, nuts
- Avoid Smoking: Reduces risk of RA progression and cardiovascular complications
- Manage Stress: Meditation, yoga, and counseling can reduce flares
- Protect Joints: Ergonomic tools, avoid repetitive stress, and use assistive devices if needed
- Sun Protection: Vitamin D supplementation if deficient
Red Flags – Seek Medical Care Immediately
- Severe joint swelling, redness, or warmth
- Sudden shortness of breath or chest pain
- Neurological symptoms such as numbness or tingling
- High fever or unexplained weight loss
- Rapid progression of joint deformity
FAQ
Q1: Can RA be cured?
A1: No, but early diagnosis and proper management can minimize flares and prevent joint damage.
Q2: Are women more affected than men?
A2: Yes, RA is 2-3 times more common in women.
Q3: Is exercise safe for RA?
A3: Yes, low-impact exercises maintain joint function and reduce stiffness.
Q4: Can RA affect life expectancy?
A4: Severe untreated RA may slightly reduce life expectancy due to systemic complications, but modern therapies improve outcomes.
Q5: What research is ongoing?
A5: Biologic DMARDs, personalized medicine approaches, and gene-targeted therapies are current research focuses.
