What rheumatoid arthritis is

Advertisement

Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease that attacks the synovium — the lining of joints — causing inflammation that eventually damages cartilage and bone. Unlike osteoarthritis (wear and tear), RA is driven by the immune system mistakenly attacking healthy joint tissue.

RA affects about 1% of the global population and is 2–3 times more common in women, most commonly beginning between ages 30 and 60. The hallmark pattern is symmetrical joint swelling — both hands, both wrists — with morning stiffness lasting more than an hour, small joints of hands and feet involved first.1

Rheumatoid arthritis: myths vs facts

RA is constantly confused with other joint problems. Here is what the evidence says:

MYTH RA is just wear and tear from ageing.

FACT Wear and tear is osteoarthritis. RA is an immune attack that destroys joints — and the treatments could not be more different. Confusing the two delays disease-modifying treatment.

MYTH A positive rheumatoid factor means you have RA.

FACT RF is positive in 70–80% of RA but is not specific. Anti-CCP antibodies are far more specific (around 98%). Classification needs 6 or more points on the 2010 ACR/EULAR criteria across four domains — no single test decides it.2

MYTH Morning stiffness is the same in all arthritis.

FACT Stiffness lasting more than an hour is the key distinguishing feature of RA versus osteoarthritis. Duration of stiffness is one of the most useful bedside clues.

MYTH You should wait until RA is severe before treating it.

FACT The opposite: the first three months after symptoms start are the window when treatment changes the long-term course most. Early referral beats wait-and-see.

MYTH RA only affects the joints.

FACT Seropositive disease can involve the lungs, blood vessels (vasculitis) and skin (rheumatoid nodules), and commonly causes anaemia of chronic disease. It is systemic, not just articular.

What to do next

Suspected RA moves fast by design — early treatment prevents irreversible damage:

  1. Get the classification checked. The 2010 ACR/EULAR criteria assign points across joint involvement, serology (RF and anti-CCP), acute-phase reactants (CRP/ESR) and symptom duration — 6 or more out of 10 classifies definite RA.
  2. Expect a DAS28 baseline. This composite score tracks activity over time: below 2.6 is remission, above 5.1 is high activity. The treat-to-target strategy adjusts therapy every 1–3 months until the target is achieved.
  3. Understand the treatment ladder. NSAIDs relieve symptoms but do not slow the disease; short-course corticosteroids bridge acute flares; methotrexate is the first-line DMARD; combination therapy follows if needed; biologics or JAK inhibitors are used when disease stays active despite conventional DMARDs. Every step is a medical decision with its own monitoring.3
  4. Know the monitoring that comes with DMARDs. Regular full blood count and liver function tests — ask your rheumatologist how often yours are due.
  5. Ask the direct questions. Are both my RF and anti-CCP positive? What is my DAS28? Do I need hand X-rays to check for joint erosions?

Practical notes

Rheumatoid arthritis is assessed visit by visit, so your own records between appointments are valuable. Note which joints are swollen or tender, how many minutes morning stiffness lasts, and a simple 0–10 rating of pain and fatigue — these are the same ingredients that go into the DAS28 score your rheumatologist calculates. Dated photos of visibly swollen joints can also help show patterns that have settled by appointment day.

Information that sharpens RA assessment includes a complete medicine list, your smoking history, vaccination status and recent infections (important because RA treatments affect the immune system), a family history of autoimmune disease, and a clear timeline of which joints were affected first and whether the pattern is symmetrical. Bring this written down — it is the history rheumatologists rely on most.

The lifestyle factors most consistently discussed in RA are stopping smoking — smoking is linked to more severe disease and poorer response to treatment — regular gentle exercise and physiotherapy to protect joint function, maintaining a healthy weight to reduce load on joints, pacing activities during flares, and joint-protection techniques an occupational therapist can teach.

Monitoring in RA is frequent at first: CRP or ESR and the DAS28 score are typically checked every one to three months while disease is active, then less often in sustained remission. Blood counts and liver tests are monitored regularly while on DMARDs, and X-rays or ultrasound of the hands and feet may be repeated periodically to check for silent joint damage even when you feel well.

In India

Rheumatoid factor and anti-CCP tests typically cost ₹800–₹2,500, while CRP and ESR are a few hundred rupees each — though prices vary by city and lab.

Look for NABL-accredited laboratories and imaging centres, which follow standardised quality processes. In major cities, most large labs offer home sample collection for the blood tests. Whatever a lab's website says about normal values, the reference range printed on your own report is the one that counts, since ranges differ between machines and assay methods.

Frequently asked questions

What is the difference between rheumatoid factor and anti-CCP?

Rheumatoid factor (RF) is positive in 70–80% of RA but is not specific — it occurs in other conditions and some healthy people. Anti-CCP antibodies are highly specific for RA (around 98%) and are the antibody that points most specifically at the disease.

What does seropositive versus seronegative RA mean?

Seropositive RA means both RF and anti-CCP are positive: generally more severe disease with higher risk of joint destruction and extra-articular complications such as lung disease, vasculitis and nodules. Seronegative RA (both negative) is diagnosed on clinical features and may run a slightly milder course, but still requires treatment.

What is DAS28?

The Disease Activity Score 28 combines tender and swollen joint counts, CRP or ESR, and the patient’s own assessment of disease activity. Below 2.6 is remission, 2.6–3.2 low activity, 3.2–5.1 moderate, above 5.1 high activity — the ‘treat-to-target’ strategy adjusts therapy until the target is reached.3

How is RA monitored over time?

Regular DAS28 scoring, CRP/ESR for inflammation, full blood count and liver function during DMARD therapy, and hand X-rays to check for joint erosions. Rising disease activity on monitoring is what prompts treatment to be stepped up.

Can rheumatoid arthritis be cured?

There is no cure, but early treatment with DMARDs can induce remission and prevent permanent joint damage. The first three months after symptoms start are the window when treatment changes the long-term course most — so early referral matters more than waiting to see.2

Why does my rheumatologist ask about smoking at every visit?
Because it directly affects your disease. Smoking is associated with developing RA, more severe joint damage, and poorer response to several RA medicines. It is one of the few risk factors you can change, which is why rheumatologists raise it repeatedly — ask about cessation support if you smoke.
Should I stop my RA medicines before a blood test?
Usually not — monitoring blood tests are meant to reflect your treatment as it is, including its effects on blood counts and liver function. Unless your doctor specifically tells you to withhold a dose, take medicines as normal and mention the timing of your last dose at the lab.
Can I get vaccinated while on RA treatment?
Most routine vaccines are recommended for people with RA, since infections are a bigger risk on immune-suppressing treatment — but the timing of live vaccines may need planning around your medicines. Tell whoever vaccinates you exactly which RA drugs you take, and check with your rheumatologist first if you are unsure.
Will my children inherit rheumatoid arthritis?
RA is not inherited in a simple predictable way like single-gene conditions. Having a parent with RA modestly raises a child's risk compared with the general population, but most children of people with RA never develop it. There is no routine screening test for children — the practical step is simply being aware of persistent joint symptoms and seeking assessment if they appear.
