    Study Notes

    Rheumatoid Arthritis Drug Treatment Overview

    • Symptom-modifying drugs and disease-modifying antirheumatic drugs (DMARDs) are used in the treatment of rheumatoid arthritis.
    • Glucocorticoids are used in severe cases of rheumatoid arthritis to prevent T lymphocytes from secreting cytokines and inhibit the formation of antibodies by B lymphocytes.
    • Glucocorticoids have immediate effects, slow down the formation of new bone erosions, and improve extra-articular symptoms, but long-term use carries risks that outweigh benefits.
    • Side effects of glucocorticoids include Cushing-like symptoms, adrenal cortex atrophy, intolerance to infection and stress, GI ulcers and bleeding, glucose intolerance, and muscle weakness.
    • DMARDs do not immediately affect symptoms and physical signs of the disease and often have a late therapeutic efficacy, with response beginning 3-4 months after starting treatment.
    • Methotrexate and sulfasalazine are the best-tolerated DMARDs, and other options include chloroquine, hydroxychloroquine, gold compounds, penicillamine, azathioprine, cyclophosphamide, cyclosporine, leflunomide, cytokine modulators, and monoclonal antibodies.
    • Methotrexate suppresses inflammation by inhibiting the formation of neutrophils, macrophages, dendritic cells, and lymphocytes.
    • Monoclonal antibodies are produced by plasma cells formed by the proliferation of uniform cells stimulated against a single antigenic determinant.
    • TNF-alpha blockers, such as adalimumab, etanercept, golimumab, infliximab, and certolizumab pegol, bind to TNF-α and cause its inactivation.
    • Methotrexate is the first choice DMARD in the treatment of rheumatoid arthritis, used in 50-70% of patients at lower doses (15-25mg per week) than those required for cancer chemotherapy.
    • Methotrexate is used to treat rheumatoid arthritis, juvenile chronic arthritis, psoriasis, psoriatic arthritis, ankylosing spondylitis, polymyositis, dermatomyositis, Wegener's granulomatosis, giant cell arteritis, and systemic lupus erythematosus (SLE).
    • Common side effects of methotrexate include nausea and mucous membrane irritation.

    Rheumatoid Arthritis Drugs: Key Points

    • Chloroquine phosphate and hydroxychloroquine sulfate are 4-aminoquinoline-derived antimalarial drugs used as backup treatment for rheumatoid arthritis and lupus erythematosus.
    • Gold compounds, including oro and sodium orothiomalate, are used in patients who do not respond to classical anti-inflammatory drugs, and their side effects include dermatitis and mucous membrane inflammation.
    • Penicillamine, a sulfhydryl chelator, is effective against some types of rheumatoid arthritis, with common side effects being itching, skin rashes, and taste disturbances.
    • Anakinra, an interleukin-1 receptor antagonist, is used in rheumatoid arthritis, Still's disease, gout, and other conditions when other treatments are ineffective, with therapeutic effects seen in 4-6 weeks for rheumatoid arthritis.
    • Leflunomide, at least as effective as methotrexate, is used in active rheumatoid arthritis and psoriatic arthritis, with therapeutic effects appearing after 4-6 weeks.
    • Prior to leflunomide treatment, complete blood counts and liver enzyme tests should be performed, and effective contraception is necessary during treatment and for two years after discontinuation.
    • Sulfasalazine is metabolized in the intestinal flora and used in juvenile chronic arthritis, ankylosing spondylitis, and associated uveitis, with common side effects being nausea, vomiting, headache, and skin rash.
    • Rituximab, a human-mouse chimeric monoclonal IgG1, is used in the treatment of chronic lymphocytic leukemia and B-cell non-Hodgkin lymphoma, in combination with methotrexate in patients not responding to other drugs.
    • Abatacept inhibits T-cell activation and is used in the treatment of moderate to severe rheumatoid arthritis and juvenile arthritis that does not respond to TNF antagonist and other DMARDs.
    • Tocilizumab, a recombinant humanized IgG1, is used to treat moderate-to-severe active rheumatoid arthritis in patients who do not respond to TNF-alpha antagonist treatment, and can cause opportunistic infections and a decrease in neutrophil and platelet count.
    • Rheumatoid arthritis drugs can cause leukopenia, anemia, stomatitis, GI ulcer, alopecia, and hepatotoxicity, and folic acid and leukoverin reduce side effects but also effectiveness.
    • Ocular disorders and neuropsychiatric disorders are dose-dependent side effects of chloroquine phosphate and hydroxychloroquine sulfate, with ophthalmoscopic monitoring necessary.
