Overview
There is no known cure for rheumatoid arthritis. However, many different types of treatment can be used to alleviate symptoms and/or to modify the disease process.
Medical Therapy
Early diagnosis of rheumatoid arthritis is helpful in treatment. Choice of treatment depends on the following factors:
- Stage of disease (eg, mild/moderate/severe).
- Associated with other comorbid conditions.
- Stage of therapy (eg, initial versus subsequent therapy in patients resistant to treatment).
- Presence of severe prognostic signs.
Non-pharmacological treatment
- Heat or cold compresses are used to reduce the swelling, pain, and stiffness.
- Orthotics and splints
- Active and passive exercise helps in restoring range of motion.
- Patient education about taking healthy diet and taking proper rest.
Pharmacological treatment
- The mainstay of treatment of rheumatoid arthritis is pharmacotherapy.
- Principles used for the treatment of rheumatoid arthritis are:
- Making an early diagnosis and taking early treatment is helpful.
- Use of disease-modifying antirheumatic drugs early in the treatment.
- Consult a specialist like a rheumatologist.
- Use of anti-inflammatory drugs and glucocorticoids as an adjuvant.
Test to be done before starting the therapy
- CBC with differentials.
- ESR and CRP
- Serum creatinine
- Screen for Hepatitis B and Hepatitis C
- Test for latent tuberculosis
- Ophthalmological testing
Various therapy used depending upon the stage of disease:
Active disease:
- Combined therapy include disease-modifying antirheumatic drugs (DMARDs) are used along with the anti-inflammatory drugs.
- The first line of the drug is Methotrexate along with anti-inflammatory drugs like NSAIDs and glucocorticoids.
- Preferred regimen : Methotrexate 7.5 mg PO weekly for 4 weeks.
- Followed by an increase in dose by 2.5mg PO or 5mg PO depending on the severity of disease and renal function.
- Monitoring of renal function is done after 4 weeks.
- Folic acid 1mg PO q24h or leucovorin weekly is usually added to MTX to avoid side effects.
