What is Rheumatoid Arthritis?

Rheumatoid arthritis is a chronic condition in which small joints of hands and feet swell symmetrically. It is the most common form of chronic inflammatory arthritis which often results in joint disability and deformity. It is diagnosed with help of some subtle clinical features such as:

  • Early morning stiffness of joints lasting for more than an hour that relieves after exercise
  • Swelling of small joints of both hands and feet

Joint is made up of bones and a capsule covering it (synovium). Capsule contains fluid known as synovial fluid. The ends of two bones are covered with a soft covering knows as cartilage. Normal synovium is thin which secrete fluid and other protective factors. In Rheumatoid arthritis, the synovium becomes greatly thickened, causing boggy swelling around joints and tendon. This process gives rise to swelling and painful joints which in turn limits the movement. Further, increased thickness of synovium leads to a thick layer called as Pannus, which damages the cartilage by blocking its nutrition. Thus cartilage becomes thin and the underlying bone gets exposed. These exposed bones rub against each other causing further irreversible damage.

Here’s everything you need to know about Bone and Joint System

‌How common is Rheumatoid Arthritis?

More than 1 million cases per year are diagnosed with it in India.

‌What are the symptoms of Rheumatoid Arthritis?

  • Pain and stiffness of small joints of hands and feet (early morning)
  • Fatigue
  • Disturbed sleep
  • Joints deformities in later stages like deviation of fingers, clawing of toes and fingers, broadening of feet
  • Knee swelling can also be seen in later stages

There are some non-articular (other than joints) symptoms also with Rheumatoid arthritis, such as:

  • Rheumatoid nodules: Subcutaneous nodules are firm and intradermal and they generally occur over pressure points
  • Anaemia
  • Dry eyes
  • Dry mouth
  • Leg ulcer
  • Ankle swelling
  • Lung diseases
  • Fatty kidney / liver

Who’s at risk for Rheumatoid Arthritis?

  • Females have more risk than males (3:1)
  • Age: 30-50 years. Chances of disease decrease after 50
  • Disease in elderly have worse outcome than young ones
  • Genetic factor: It accounts for 60% disease susceptibility
  • Chronic smokers

What are the causes of Rheumatoid Arthritis?

No specific cause has been found yet. However, association with HLA DR4 gene is considered to be one of the causes.

‌What are the complications of Rheumatoid Arthritis?

  • Permanent bone deformity
  • Septic Arthritis: Joint swelling associated with infection

‌How is Rheumatoid Arthritis diagnosed?

The condition is diagnosed in the following ways:

  • Lab examination: Blood count may show less Haemoglobin
  • Serology shows:Rheumatoid factor (RA Factor) positive and ACPA (anti-citrullinated peptide antibody) positive
  • X-Ray shows destruction of bones near joint
  • Doppler ultrasound of joints is required to check the synovitis and effectiveness of drugs

‌How is Rheumatoid Arthritis treated?

Drugs

  • NSAIDs: Non-steroidal anti-inflammatory drugs or commonly known as pain killers are very useful in stopping symptoms and slowing progression of disease
  • But in elderly, these drugs can cause other side effects like gastric upsets, hence should be given with caution
  • Steroids: Oral steroids are not of much use. But injecting steroids into the joint can help to reduce local swelling and can be one of the options.
  • Disease-modifying antirheumatic drugs (DMARDs) like Methotrexate (an anti-cancer drug, used in low doses), Sulfasalazine, Hydroxychloroquine, etc.
  • Biologic drugs like Infliximab, Adalimumab, etc.

Surgery

Surgery has a useful role in long term approach, but is less frequently needed. Single joint arthritis can be treated effectively by removing thickened synovium. But risk benefit ratio should always be decided by surgeon.

Other effective methods are exercise in hydrotherapy pool and occupational therapy.
