Rheumatoid Arthritis: Walking the Walk

Author: Virginia Bartok, RPh


The struggles of managing rheumatoid arthritis and how pharmacists can help are illustrated through one patient’s experience.

Meet Ed. Ed is a 75-year-old mechanic who suffers from rheumatoid arthritis (RA). One of 1.5 million Americans with RA,1,2 he experiences severe pain, stiffness, and inflammation. Both hands are misshapen with deformed joints, and at its most painful, he forgoes recreational activities because of his disability. He has trouble with some of the finer tasks he used to do with ease.

His rheumatologist can’t tell him why he developed RA, and says it’s linked to too many factors to pinpoint 1 cause—genetic, environmental, immunologic, and infectious. Like many RA patients,1-4 Ed has had several bouts of depression and anxiety. He attempted suicide once following extreme feelings of helplessness. At age 58, his depression was so serious he walked off the job and stayed home for 2 years, isolated and self-loathing. He returned to work but is now retired.

Ed’s progression typifies patients with RA in many respects, although women are 2.5 to 3 times more likely to have RA than men.1,2 Ed was diagnosed at 42 years of age when he noticed changes in the small joints of his fingers, wrist, and feet. After more than 30 years with RA, Ed has the condition in most joints, and also has some lung tissue damage, hardening of the arteries, and spinal deformity. In addition, rheumatoid vasculitis has reddened and irritated his skin. Table 1 summarizes RA’s clinical presentation.

Wishing for a Cure

Ed and Ed’s family ask often about a cure, but each time his rheumatologist responds, “We don’t have one yet.” The rheumatologist follows treatment guidelines, and Ed—a logical thinker who always reads the manual when he does any mechanical task—has appreciated knowing that his doctor follows an algorithm, too. The American College of Rheumatology (ACR) guidelines (updated in 2012 and available at http://tinyurl.com/lexmr7p) use a structured yet flexible approach to6: Since his diagnosis indicating high disease activity and poor prognosis, Ed has used a multitreatment approach that starts with nonpharmacologic measures. Ed eats well, stretches each morning, exercises, and rests when he feels fatigued. During periods of depression, which he now recognizes sooner, he sees a mental health therapist. Periodically, he also sees a physical and an occupational therapist—this supports the ACR guideline goal of helping patients maintain use of affected joints and improve their overall quality of life.6

The Drugs: Progressively Better

Over the years, Ed has taken numerous drugs, switching when side effects occurred or pain increased. Throughout his disease, he took and continues to take acetaminophen and nonsteroidal anti-inflammatory drugs as needed. He has also been on corticosteroids, which he dislikes, and several disease-modifying antirheumatic drugs (DMARDs), hydroxychloroquine, minocycline, and methotrexate.4,7,8 He and his rheumatologist knew that they had other options (azathioprine, sulfasalazine, leflunomide, cyclosporine), but after discussion, they put them aside.1,2,4

In keeping with ACR guidelines, Ed’s rheumatologist used aggressive therapy early because it may delay or decrease joint destruction.7,9,10 He has also ensured that Ed’s vaccinations are current (eg, pneumococcal, influenza, hepatitis B, human papillomavirus, herpes zoster); people who have RA need as much protection as possible.5,6 Once the FDA started approving the biologic DMARDs (also called the biologic response modifiers; Online Table 2), Ed and his rheumatologist discussed risk-benefit. Ed was one of the first patients outside of clinical trials to use infliximab as an intravenous infusion every 2 months. He noticed improvement within 8 weeks, but he has also continued his methotrexate. When newer agents became available that could be given subcutaneously, he made an informed decision to remain on infliximab because he does not like giving himself shots.

Agents FDA Approval Notes
Tumor necrosis factor (TNF) Inhibitors
inFLIXimab (Remicade) August 24, 1998
  • Infusion of biologics may cause fever, chills, body aches, and headache; consider premedicating with diphenhydramine.
  • All are injectables administered subcutaneously or intravenous route depending on agent and each manufacturer’s recommendations.
  • Used as monotherapy or in conjunction with methotrexate.
  • Common side effects include upper respiratory infections, pneumonia, urinary tract infections, and skin infection, and nausea.
etanercept (Enbrel) November 2, 1998
adalimunab (Humira) December 31, 2002
certolizumab pegol (Cimzia) April 22, 2008
golimumab (Simponi) April 24, 2009
T-cell Costimulatory Blocking Agent
abatacept (Orencia) December 23, 2005
  • Given IV or subcutaneously.
  • Responses typically observed within 3 months of therapy.
  • Avoid live vaccines while on abatacept and for 3 months after discontinuation.
  • Abatacept contains maltose and can falsely elevate blood glucose readings with certain blood glucose monitors on infusion days.
  • Common side effects include headache, upper respiratory infection, sore throat, and nausea.
CD20-positive B-cell Depletion
riTUXimab (Rituxan) March 1, 2006
  • Used in combination with methotrexate in adults who exhibited inadequate responses to one or more TNF inhibitors.
  • Patients should receive IV corticosteroid 30 minutes before each IV infusion.
  • Common adverse effects may include hives, itching, swelling, difficulty breathing, fever, chills, and changes in blood pressure.
Interleukin-6 (IL-6) Receptor Antagonist
Tocilizumab (Actemra) January 8, 2010
  • Administered via IV infusion or subcutaneously and has associated REMS program.
  • Increased risk of developing serious infections.
  • Common ADRs include upper respiratory tract infections, nasopharyngitis, headache, hypertension, injection site reaction, and increased ALT.
Human Recombinant IL-1 Receptor Antagonist
Anakinra (Kineret) November 14, 2001
  • Administered subcutaneously.
  • Most common ADRs: injection site pain, erythema, itching , fever, and nausea

For newly diagnosed patients, starting biologics within 6 months of symptom onset delays RA progression more effectively than later treatment. It may also prompt remission.4,5,7-10 Current ACR guidelines still encourage early treatment with the use of triple-combination DMARD regimens or a biologic with or without methotrexate for patients with high disease activity and a poor prognosis. However, the ACR guidelines do not recommend biologics for early RA in patients with low to moderate disease activity and good prognoses.7,6

In 2012, Ed switched to a new Janus kinase pathway inhibitor, tofacitinib (Xeljanz). Tired of infusions, he decided to try this new oral agent. He’s aware that it may elevate cholesterol and liver enzyme tests and decrease blood counts. It carries the same risk of serious infections and cancers as the biologic DMARDs. He finds that taking it twice daily is no problem. Tofacitinib allowed him to stop his methotrexate, and he hasn’t experienced tofacitinib’s most common adverse effects: upper respiratory tract infections, headache, diarrhea, and nasopharygitis.13,14

Final Note

RA patients like Ed are encouraged by recent drug and biologic approvals. Clinicians are too, and informed clinicians recommend early, aggressive treatment. The newer agents are also steroid-sparing, a benefit that patients and clinicians embrace. Pharmacists can help patients model Ed’s behaviors—he monitors his symptoms, partners in his treatment plan, and sees his health care professionals routinely.

Postscript: Ed passed away in his sleep in November 2013. His physicians suspect he had a fatal myocardial infarction. Due to his age and comorbidities, the family did not ask for an autopsy. At his memorial service, they noted his brave approach to this disabling disease.
