    Study Notes

    Disclosures

    • Steven C Kimmel has research support from various pharmaceutical companies, including Roche, Novartis, and Amgen.
    • Other listed companies include Genetech, Wyeth, Centacor, and Pfizer among others.

    Osteoarthritis and Rheumatoid Arthritis

    • RA therapies initiate with the same baseline as osteoarthritis (OA), involving physical therapy and analgesics.

    RA: Therapy

    • Baseline treatment includes NSAIDs, steroid injections, and potential surgical interventions.
    • Other therapeutic options consist of oral steroids, conventional DMARDs (cDMARDs), biologic DMARDs (bDMARDs), and JAK kinase inhibitors.

    RA Linear Progression

    • RA progresses through defined stages: early, intermediate, and late, with increasing inflammation and disability linked to disease duration.
    • Early and late interventions significantly affect outcomes in disease severity.

    RA Treatment Approaches

    • Various medications for RA include:
      • Biologic agents: target specific components of the immune system.
      • Steroids: may provide rapid anti-inflammatory benefits but do not conclusively alter disease progression.
      • NSAIDs: provide pain relief but do not prevent RA progression, with notable adverse effects including gastric issues and renal insufficiency.

    NSAID Agents

    • Commonly prescribed and available OTC, NSAIDs relieve pain but carry risks.
    • Adverse effects include dyspepsia, gastrointestinal bleeding, renal issues, and possible cardiovascular concerns.
    • NSAIDs represent a significant cause of mortality in certain medical groups.

    Pros and Cons of Steroid Therapy

    • Pros:
      • Quick anti-inflammatory and immunosuppressive effects beneficial for bridging DMARD therapy initiation.
    • Cons:
      • Long-term use can lead to adverse effects such as skin thinning and increased risk of infections.
      • Steroid use can cause osteopenia and may decrease overall lifespan.

    RA: Choice of cDMARD

    • Mild features might warrant the use of Sulfasalazine or Hydroxychloroquine, avoiding use with specific contraindications.
    • Aggressive features typically require Methotrexate or Leflunomide.

    DMARDs: Risks

    • All DMARDs can present serious side effects.
    • Hydroxychloroquine can lead to retinal deposits after 5 years.
    • Methotrexate poses risks to lungs, liver, and bone marrow, necessitating vigilant monitoring for toxicity.

    RA: Biologic DMARDs

    • Available Biologic Agents:
      • Infliximab: Chimeric anti-TNF-α monoclonal antibody.
      • Etanercept: TNF-receptor fusion protein targeting TNF-α.

    Disclosures

    • Steven C. Kimmel, MD has received grant research support from various pharmaceutical companies including Roche, Novartis, Amgen, Genentech, and Pfizer.

    Osteoarthritis and Rheumatoid Arthritis Overview

    • Management of Rheumatoid Arthritis (RA) parallels Osteoarthritis (OA) focusing on physical therapy, analgesics, NSAIDs, injections, and surgery.

    RA Therapy Options

    • Baseline therapy includes physical therapy, analgesics, NSAIDs, and steroid injections.
    • Conventional Disease-Modifying Anti-Rheumatic Drugs (cDMARDs) and biologic DMARDs (bDMARDs) are available for treatment.
    • Oral biologic DMARDs, specifically JAK Kinase inhibitors, present new therapeutic options.

    RA Linear Progression

    • Disease progression illustrated in stages: early RA, intermediate, and late RA occurring over 0 to 30 years.
    • Key markers include severity, inflammation levels, radiographic evidence, and disability.

    Vaccination Guidelines

    • Avoid live virus vaccines in RA patients and wait 4 weeks after live vaccination before initiating biologic treatments.

    Current Management Approach

    • Focus on early diagnosis and treating to a target based on objective disease activity measures.
    • Emphasizes early introduction of cDMARDs and biologic agents, along with adequate control of co-morbid conditions.

    Treat to Target Remission

    • Clinical and immunological remission defined by low disease activity, absence of synovitis, and no evidence of ongoing disease via imaging or serology.

    Co-Morbid Conditions Associated with RA

    • RA increases the risk of osteoporosis and cardiovascular diseases.
    • Updated vaccination recommendations for RA patients include killed virus vaccines like Shingrix, Fluviron, and Pneumovac.

    Prognosis of RA

    • Historical treatments yielded remission rates below 20%; biopharmaceutical advancements now show 60% complete remission rates.

    Extrajoint Manifestations of RA

    • Notable extra-articular conditions include rheumatoid nodules, uveitis, pulmonary diseases, cardiac issues, and skin manifestations.

    Adult Onset Still's Disease (AOSD)

    • Characterized by daily fevers, arthritis, and specific lab markers (Rheumatoid Factor and ANA levels).
    • Complications can include pericardial tamponade and macrophage activation syndrome.

    AOSD Treatment

    • High doses of NSAIDs may provide relief, with steroids reserved for non-responders and severe cases, alongside DMARDs and biologics.

    Felty's Syndrome

    • Associated with seropositive RA, characterized by granulocytopenia and splenomegaly, treated with GM-CSF and standard RA therapies.

    Women’s Health Considerations in RA

    • High prevalence of autoimmune diseases in women, with emphasis on reproductive health during preconception, pregnancy, and lactation.
    • Certain medications are safe during pregnancy, while others carry significant risks that necessitate careful planning.

    Disability in Artistic Context

    • The work and legacy of Pierre-Auguste Renoir illustrate the impact of rheumatoid arthritis on disability, contributing to discussions on patient experiences.

    Differential Diagnosis in Symmetric Polyarthritis

    • Interpretation of autoimmune markers assists in differentiating between RA and other conditions like SLE, with specific autoantibody testing informing the clinical picture.

    Differences Between Osteoarthritis and Rheumatoid Arthritis

    • Osteoarthritis is primarily degenerative, while rheumatoid arthritis is an inflammatory disease of uncertain origin.
    • RA focuses on managing disease activity and improving function, often requiring surgical intervention only after other therapies fail.
