Rheumatoid arthritis - Symptoms and causes - Mayo Clinic
Rheumatoid arthritis is an ongoing, called chronic, condition that causes pain, swelling and irritation, called inflammation, in the joints. But it also can damage other parts of the body.

Rheumatoid arthritis - Wikipedia
Rheumatoid arthritis (RA) is a long-term autoimmune disorder that primarily affects joints. It typically results in warm, swollen, and painful joints. Pain and stiffness often worsen following rest. Most commonly, the wrist and hands are involved, with the same joints typically involved on both sides of the body.

Rheumatoid Arthritis (RA): Symptoms, Stages & Treatment
What is rheumatoid arthritis? Rheumatoid arthritis (RA) is a chronic (ongoing) autoimmune disease that causes pain, swelling and stiffness in the lining of your joints (synovium). It most commonly affects the joints in your fingers, hands, wrists, knees, ankles, feet and toes.

Rheumatoid Arthritis: Causes, Symptoms, Treatments and More
Rheumatoid arthritis (RA) causes joint inflammation and pain. It happens when the immune system doesn’t work properly and attacks the lining of the joints, called the synovium.

Rheumatoid Arthritis: Signs, Causes, Treatments, and Care - WebMD
Rheumatoid arthritis (RA) is an autoimmune arthritis where your body’s immune system attacks its own tissue, including joints and internal organs, causing pain and swelling.

Rheumatoid Arthritis: Symptoms, Causes, Treatment, and More
Rheumatoid arthritis (RA) is an autoimmune disease in which the body’s immune system attacks its own tissue. Symptoms include pain, swelling, and stiffness of the joints. When untreated, joint damage and deformities can eventually lead to difficulty moving the hands, wrists, knees, and/or hips.

What is Rheumatoid Arthritis?
What is Rheumatoid Arthritis? Rheumatoid arthritis (RA) is a disease where the immune system attacks healthy cells. This can lead to joint damage, inflammation, and pain. Symptoms can be mild to severe. When the disease is severe, your joints may change shape and you may have trouble moving.

Common Rheumatological Symptoms

Joint Pain (Arthralgia) — Persistent discomfort or soreness in one or more joints caused by inflammation, wear and tear, or underlying autoimmune responses.
Morning Stiffness — Reduced joint mobility and tightness upon waking, often lasting over 30 to 60 minutes in inflammatory conditions like rheumatoid arthritis.
Joint Swelling and Edema — Visible enlargement of affected joints resulting from fluid accumulation in the synovial membrane and inflamed surrounding tissue.
Localized Warmth and Redness — Elevated temperature and erythema skin discoloration surrounding inflamed joints due to increased blood flow from localized inflammation.
Systemic Fatigue — Overwhelming exhaustion and lack of energy caused by ongoing chronic inflammatory cytokine activity throughout the body.
Raynaud's Phenomenon — Temporary color changes in fingers or toes turning white, blue, and red in response to cold or stress due to vascular spasms.
Malar or Butterfly Rash — Red or purplish facial rash spanning across the bridge of the nose and cheeks, classically associated with systemic lupus erythematosus.

Milestones in Rheumatology History

c. 400 BC: Hippocratic Corpus Coining — Hippocrates uses the term "rheuma" to describe body humors flowing into joints, establishing the early classical concept of joint inflammation.
1592: Formal Definition of Rheumatism — French physician Guillaume de Baillou introduces the modern term "rheumatism" to distinguish systemic acute arthritis from localized gout.
1800: Clinical Description of Rheumatoid Arthritis — Augustin Jacob Landré-Beauvais publishes the first detailed clinical description separating rheumatoid arthritis from gout, calling it "asthenic gout."
1859: Naming of Rheumatoid Arthritis — Sir Alfred Baring Garrod formally coins the term "rheumatoid arthritis" to clearly differentiate the inflammatory autoimmune condition from osteoarthritis and gout.
1940: Discovery of the Rheumatoid Factor — Erik Waaler discovers autoantibodies in the blood of patients with rheumatoid arthritis, laying the groundwork for serological autoimmune diagnostics.
1948: Introduction of Corticosteroid Therapy — Philip Hench and Edward Kendall demonstrate the dramatic anti-inflammatory effects of Compound E (cortisone) in treating rheumatoid arthritis, earning the Nobel Prize.
1998: Emergence of Biologic DMARDs — The FDA approves the first TNF-alpha inhibitors, ushering in the modern era of targeted biologic therapies for autoimmune rheumatic diseases.

Current Trends in Rheumatology Research

Chimeric Antigen Receptor (CAR) T-Cell Reset Therapy — Investigating engineered cellular therapies to achieve drug-free, durable clinical remissions by completely depleting pathogenic autoantibodies in severe refractory lupus and systemic sclerosis.
Selective TYK2 and Oral JAK Pathway Inhibition — Developing highly targeted, small-molecule oral inhibitors like deucravacitinib that disrupt specific cytokine signaling pathways while minimizing broader off-target side effects.
Targeted Pathogenic T-Cell and B-Cell Depletion — Evaluating novel biologics, such as rosnilimab and ianalumab, designed to selectively deplete overactive immune cell subpopulations involved in rheumatoid arthritis and Sjögren's disease.
Biomarker-Driven Precision Medicine — Utilizing pharmacogenomics and molecular biomarkers to predict individualized therapeutic responses and match systemic autoimmune conditions to specific biological mechanisms.
Subclinical Interception and Disease Prevention — Identifying seropositive individuals early using high-risk autoantibody profiles to initiate preventive targeted therapies before irreversible joint damage occurs.
Artificial Intelligence and Predictive Disease Modeling — Deploying machine learning algorithms across electronic health records and imaging modalities to forecast inflammatory flares and refine diagnostic accuracy.
