Rheumatoid arthritis

Verification

• Verification: "Rheumatoid arthritis (Rheumatoid arthritis, RA)" is a medically recognized disease name. The content below is a structured summary that prioritizes the provided information (RAG) and supplements it with general medical knowledge.

1. Disease description (causes and symptoms)

• Definition and pathophysiology
  • Rheumatoid arthritis is a chronic inflammatory disease of the synovium that usually begins in the small joints of the hands and feet symmetrically and spreads to other movable joints, such as the knees and shoulders.
  • An autoimmune response (genetic predisposition + environmental triggers) causes synovial proliferation and accumulation of inflammatory effusion, eroding cartilage and bone and leading to joint destruction and deformity.
  • Immune-related markers (rheumatoid factor (RF) and anti-CCP antibodies) help with diagnosis and prognosis.
• Causes
  • No single exact cause has been identified. Genetic predisposition and environmental triggers (such as infection and smoking) are thought to interact and trigger an autoimmune response.
• Main symptoms
  • Joint pain and tenderness, joint swelling, and warmth
  • Morning stiffness — stiffness in the finger joints that usually lasts for at least 1 hour
  • Symmetric polyarthritis (fingers, wrists, etc.)
  • Generalized weakness and fatigue
  • Joint deformity (e.g., finger deformity) and loss of function as the disease progresses
• Systemic complications (rarely, in severe cases)
  • Possible involvement of the lungs (interstitial lung disease), heart (pericarditis and myocardial disease), eyes (dry eyes and uveitis), skin (rheumatoid nodules), kidneys, and other organs

2. Treatment methods (latest standard treatment, medications·procedures·surgery, lifestyle management, precautions)

• Treatment goals
  • Early suppression of inflammation, prevention of joint destruction and deformity, and maintenance of function and quality of life
• Medication treatment
  • First-line treatment (symptom control): NSAIDs (analgesics and anti-inflammatory drugs), short-term low-dose glucocorticoids (symptom relief and bridge therapy)
  • Disease-modifying antirheumatic drugs (DMARDs)
    • Early administration is recommended to induce remission and suppress long-term disease progression
    • Conventional first-line medication: methotrexate (MTX) — the most widely used
    • Other conventional DMARDs: sulfasalazine, leflunomide, etc.
  • Biologic agents and targeted therapies
    • TNF inhibitors, IL-6 inhibitors, B-cell-targeted therapy (rituximab), JAK inhibitors, etc. — used when the response to existing treatment is insufficient or in specific situations
    • Infection risk and regular monitoring are required
• Non-medication treatment
  • Physical and occupational therapy: maintaining joint flexibility and strength, and using orthoses
  • Lifestyle: smoking cessation (especially because smoking is associated with worsening disease in anti-CCP-positive patients), regular joint protection (avoiding excessive loads)
  • Vaccination: influenza and pneumococcal vaccines, among others, are recommended before and after immunosuppressive treatment (caution with live vaccines)
• Surgical treatment
  • When joint deformity or functional impairment is severe, or conservative treatment fails: synovectomy, arthroplasty, joint replacement surgery, etc.
  • Early rehabilitation after surgery is recommended
• Precautions
  • Glucocorticoids are effective for short-term symptom relief, but long-term use increases the risk of side effects such as osteoporosis, infection, and metabolic abnormalities — the lowest dose for the shortest duration is recommended
  • When using DMARDs/biologics, monitoring for hepatic and hematologic toxicity and infection risk (including tuberculosis reactivation) is necessary
  • Because it takes several weeks to several months to assess treatment effectiveness, patience and regular follow-up are necessary

3. Checklist before an outpatient visit (including items to bring and example questions)

• Items to bring (recommended)
  • A list of currently used medications (including prescription drugs, OTC medications, and herbal medicines), along with doses and dosing intervals
  • Previous test results (blood tests, imaging tests, chest X-ray/TB test results, etc.) or test reports
  • A record of symptom changes (when they began, duration of morning stiffness, location and severity of pain, and presence of swelling)
  • Limitations in daily activities (work, exercise, sleep problems, etc.)
• Main items to be assessed during the outpatient visit
  • Number of affected joints (which joints and whether involvement is symmetric), duration of morning stiffness, systemic symptoms (fever, weight loss, and fatigue), history of past infections (such as tuberculosis), and whether there are plans for pregnancy
• Simple checklist before the visit (for patients)
  • Have the symptoms persisted for at least 6 weeks recently?
  • Do you currently have a fever, shortness of breath, or signs of an acute infection?
  • Are you pregnant or planning a pregnancy?
  • Have you recently received any vaccinations (especially live vaccines)?

4. Examples of general questions to ask the doctor

• "What are the main side effects and monitoring requirements of this medication (e.g., methotrexate)?"
• "When should I expect the treatment to start working, and what is the next step if it does not work?"
• "What should I watch out for in daily life over the long term, and what exercises and nutritional measures are recommended?"
• "Which vaccinations should I receive while undergoing immunosuppressive treatment?"

5. Examples of disease-specific questions

• "I am anti-CCP-positive (or RF-positive). How does this affect my prognosis (risk of joint destruction) and treatment choices?"
• "I am planning a pregnancy. Should I stop or switch my current DMARD (e.g., methotrexate)? What treatment options are available during pregnancy?"

Brief summary (key points)

• Rheumatoid arthritis is a chronic autoimmune inflammatory disease of the synovium, and early diagnosis and early DMARD treatment are important for protecting the joints and improving the prognosis.
• Treatment combines medications (DMARDs such as methotrexate and biologics), short-term steroids, physical therapy, and surgery when necessary; regular monitoring and management of infections and side effects are essential.
• Before the outpatient visit, prepare a record of your medications, test results, and symptoms, and clearly discuss treatment goals, side effects, pregnancy, and prognosis with your doctor.
