Rheumatoid Factor (RF) therapy primarily targets autoimmune diseases such as Rheumatoid Arthritis (RA). This treatment modulates immune system function to reduce excessive antibody production, alleviating joint inflammation, tissue damage, and systemic symptoms. The core goal is to inhibit disease progression and improve patients' quality of life.
Treatment strategies include medication, biologic agents, and immunomodulatory therapies. Physicians tailor personalized plans based on disease severity, patient age, and comorbidities. Early treatment can significantly reduce the risk of irreversible joint damage.
The main treatment types include:
These drugs share mechanisms that block key steps in autoimmune reactions. For example, biologics use monoclonal antibodies to precisely target specific molecules, while DMARDs broadly regulate the immune system, requiring regular monitoring of liver and kidney functions.
Primarily suitable for RA patients, especially those positive for RF or anti-CCP antibodies. Also used in other autoimmune-related diseases, such as Sjögren's syndrome and systemic lupus erythematosus complications. Patients unresponsive to traditional drugs may switch to biologics.
Doctors evaluate suitability based on RF levels and clinical presentation. For example, high RF concentrations with joint destruction signs favor the use of potent immunomodulatory therapies.
DMARDs are usually administered orally or via periodic intravenous injections, with initial doses adjusted according to body weight. Biologics are often given via subcutaneous injection or IV infusion, with frequencies ranging from weekly to every few weeks. JAK inhibitors are taken orally daily.
Initial treatment may include corticosteroids or NSAIDs for rapid symptom relief. Dosages are dynamically adjusted based on efficacy and side effects, strictly following physician instructions without self-modification.
Main benefits include:
Long-term follow-up shows that early use of symptom-relieving drugs can achieve clinical remission in 70% of patients. For those unresponsive to traditional medications, biologics can increase response rates to 50-60%.
Common side effects include:
Serious risks include: severe infections (such as tuberculosis reactivation), cardiovascular events, and certain cancers. Screening for latent infections is necessary before using biologics.
Contraindications include:
Regular monitoring of blood counts, liver function, and infection markers is required during treatment. Pregnant women or those planning pregnancy should evaluate drug effects on the fetus; some biologics may be restricted.
Combining with NSAIDs may increase gastrointestinal bleeding risk. DMARDs combined with immunosuppressants (like corticosteroids) may elevate infection risk. Some biologics used with anticoagulants require dose adjustments.
Patients should inform their physicians of all medications, including OTC drugs and supplements. Live vaccines should be avoided during treatment; inactivated vaccines are preferred.
Clinical trials show that DMARDs alone can achieve clinical improvement in 50% of patients, while combination with biologics can increase response rates to 80%. JAK inhibitors have demonstrated a 40-60% reduction in joint tenderness scores in phase III trials.
Long-term studies indicate that continuous treatment over five years can slow joint destruction by 60-70%. About 85% of successful cases maintain daily functional activities.
If primary treatments are unsuitable, options include:
Traditional Chinese medicine, such as Tripterygium wilfordii preparations, may be used as adjunct therapy in certain regions, but liver toxicity must be considered. Alternative therapies should be discussed thoroughly with the primary physician.
Patients should regularly monitor blood indicators such as Erythrocyte Sedimentation Rate (ESR) and C-reactive Protein (CRP) to assess inflammation. Liver and kidney functions should also be checked, especially when using immunosuppressants or biologics. Follow-up visits every 2 to 3 months are recommended, with records of joint pain and activity levels to adjust medication plans accordingly.
How should I respond if I develop infection symptoms after using biologics?If symptoms like fever, cough, or unexplained inflammation occur, stop medication immediately and notify your physician. During treatment, avoid contact with infection sources, such as live vaccines or crowded places. The doctor may suggest prophylactic antibiotics or dose adjustments to reduce infection risk.
How can physical therapy complement drug treatment to improve outcomes?Physical therapists design joint stretching and muscle strengthening exercises to relieve stiffness and pain. Daily low-intensity exercises, such as aquatic therapy or joint mobilization after heat therapy, are recommended. Avoid excessive joint loading during therapy and coordinate with medication to control inflammation for optimal results. How to prevent symptom relapse after stopping medication?
Post-discontinuation, ongoing monitoring for at least 6 to 12 months is necessary, along with maintaining regular low-intensity exercise. Gradual dose reduction rather than abrupt cessation is advised, with adjustments based on blood markers. Quitting smoking, controlling weight, and avoiding cold exposure to joints are also important preventive measures.
What are the differences in treatment response between biologics and traditional DMARDs?Biologics rapidly suppress the immune system, often providing symptom relief within weeks but with increased infection risk; traditional DMARDs (like methotrexate) act more slowly (2-3 months) but have better long-term safety profiles. Physicians choose monotherapy or combination therapy based on inflammation severity and comorbidities, with regular evaluation of efficacy and side effects.
