Rheumatoid Arthritis

How to pronounce it: Rheumatoid - roo·muh·toyd


AiArthritis defines Rheumatoid Arthritis as:

Rheumatoid arthritis (RA) is a chronic inflammatory condition that can affect your joints, tissues, and organs. RA is an autoimmune disease where the immune system mistakenly attacks healthy tissue.

Symptoms & Characteristics

Common in All AiArthritis Diseases

Flares: Periods of worsening symptoms are called flares. A flare can last for hours, days, weeks, or months.


Physical Activity: Condition improves with activity and exercise and worsens with rest.


Comorbidities: When inflammation is left uncontrolled due to lack of proper treatment, comorbidities can develop. 70% of patients with chronic, lifelong disease will develop comorbidities, including dual or triple diagnoses.


Family History: Autoimmune diseases often run in families, indicating a potential genetic predisposition where that gene can cause disease. Autoinflammatory diseases can occur multiple times in a family, but is based off of genetic mutation. It is not a gene that causes the disease— but a mutation on the gene that can cause the disease which can then be passed on to the next generation.

"Auto" Symptoms

Fatigue: Severe fatigue or exhaustion that may not be helped by caffeine/stimulants and can happen even after a long period of rest.


Cognitive Dysfunction: Brain fog  or periods of time where thinking gets clouded and it becomes difficult to concentrate.


Flu-like symptoms: Without having the flu- nausea, muscle weakness, and general malaise.


Fever: Typically low grade in autoimmune (with exception of juvenile idiopathic arthritis) and higher grade in autoinflammatory (% strongly varies per disease).

Inflammatory Arthritis Symptoms

Stiffness: Severe stiffness in one or more joints, especially in the morning or after sitting for long periods of time. 


Joint Pain: Episodes of joint pain that may last for hours, days, or even weeks, that can appear and disappear suddenly. Often described as “jumping pain” into different locations.


Typically the joint pain will coincide with one or more “Auto” symptoms and start and stop suddenly - for no apparent reason (which is called a "flare"). Some people will experience all of the above symptoms, others only a few.


 If you have any of the arthritis features, and at least one of the “Auto” features, please consult your physician about a referral to a specialist.


Symptoms Often Associated with Rheumatoid Arthritis

  • Firm lumps under the skin, often around the elbows or hands
  • Pain and swelling, usually affecting both sides of the body
  • Redness and warmth around the joints
  • Larger joints in the hands (like knuckles) are often affected first, but any joint can be involved

  • Diagnosing Rheumatoid Arthritis

    Diagnosing rheumatoid arthritis (RA) involves a combination of physical exams, blood tests, imaging (such as MRIs), and family history. Doctors typically look for:


    • More than one joint being affected

    • Chronic symptoms lasting over 6 weeks

    • Swelling, redness, or warmth in the joints (although these may not always be

    present)

    • Other symptoms that help distinguish RA from osteoarthritis


    Blood tests are important for diagnosing RA and may show markers of inflammation, such as ESR and CRP. A positive Rheumatoid Factor (RF+) is another common indicator, though it is not required for a diagnosis, as many people with RA do not have this marker in their blood. Similarly, anti-CCP (cyclic citrullinated peptide) antibodies are highly specific for RA and can help identify the disease early, even in patients who do not yet show symptoms. High levels of anti-CCP are often associated with more severe disease and a higher risk of joint damage.


    Both RF and anti-CCP are part of the diagnostic and classification guidelines for RA.However, some patients may be negative for both markers, a condition referred to as seronegative RA. This means the absence of these specific antibodies does not rule out RA, and diagnosis may still be made based on symptoms, imaging, and other blood tests.


    To further aid in diagnosis, doctors may use a points system developed by the American College of Rheumatology (ACR) and the European Alliance of Associations for Rheumatology (EULAR). This system assigns points based on test results and symptoms to help determine if you have rheumatoid arthritis.

  • What Fellow Rheumatoid Arthritis Patients Want You to Know

    • Sometimes you may feel a locking feeling in the joints, like if you grab a hair brush or a cabinet handle - suddenly your fingers may stop moving while the rest of your hand continues in motion. This doesn't feel good.

    • Joints like your jaw can be affected.  Also the vocal chords, called the cricoarytenoid joint (although this is not common)

    • You CAN HAVE RA without positive blood work! You may hear some patients say they have "seronegative RA" or "seropositive RA". This is referring to their blood work. If a patient has "seronegative", it means they were diagnosed with RA and had no positive markers (inflammation, RF +, etc.) in their blood (normal bloodwork). 

    • A lot of patients choose not to use the word "arthritis" because they feel that's the only word others hear and think it's the same as the most common type of arthritis, osteoarthritis - caused by aging, wear and tear, overuse. While there has been movements in the past to try and change the name, there are many reasons why this is not likely to happen.

  • Interesting Facts about Rheumatoid Arthritis

    • There used to be a diagnosis of Juvenile Rheumatoid Arthritis (JRA) decades ago, but after it was realized that juvenile arthritis onset is not exactly the same disease as RA, it was changed to Juvenile Idiopathic (no known cause) Arthritis, or JIA. You may still hear people refer to it as JRA, especially if this was their diagnosis as a child.

    • While some adults originally diagnosed with either JRA or JIA may refer to their current diagnosis as Rheumatoid Arthritis (RA), it's really a matter of choice. Some adults still say JRA/JIA OR will say JRA/JIA/RA.

    • Evidence of RA-like symptoms has been found in skeletal remains of Native Americans dating back to at least 4500 B.C. This suggests that RA has been affecting humans for thousands of years. However, RA was not widely recognized in Europe until the 19th century.

    • The term “rheumatoid arthritis” was coined in 1859 by British rheumatologist Alfred Baring Garrod. “Rheumatoid” comes from the Greek word “rheuma,” meaning “that which flows,” referring to the characteristic joint swelling.
