Inflammatory arthritis

The term Inflammatory arthritis covers a variety of autoimmune diseases that include inflammation in the joints, which can result in chronic pain and changes to the structure of the bones. Autoimmune diseases are result of your immune system malfunctioning and attacking the body’s own healthy tissue. Inflammatory arthritis may also affect other systems in the body, including internal organs, eyes, tendons, vascular system, and others.

The most common types of inflammatory arthritis are:

Ankylosing Spondylitis

AS mostly affect the spine, although other joints in the body can also be involved. Internal organs are only rarely affected. AS is three times more common in men.

Juvenile Arthritis

JA is an umbrella term covering a variety of types of inflammatory arthritis affecting children under 16. Depending on the specific type of JA, different systems in the body may be affected. Types of JA include Juvenile Idiopathic Arthritis, juvenile lupus, Juvenile dermatomyositis, and Kawasaki disease.

Mixed Connective Tissue Disease

MCTD includes symptoms of several other diseases, especially lupus, scleroderma, and polymyositis. It can cause extreme swelling in the fingers, fatigue, malaise, muscle pain, and Raynaud’s.


Myositis primarily involves inflammation and weakness in the muscles that are close to the trunk or center of the body. It can also include inflammation in joints, skin, and internal organs. Types of myositis include dermatomyositis, polymyositis, and inclusion body myositis.

Psoriatic Arthritis

PsA may affect some people who have psoriasis, a noncontagious autoimmune disease that causes plaques of scales on the skin. PsA may resemble rheumatoid arthritis, but tends to have asymmetrical joint involvement.

Reactive Arthritis

Reactive Arthritis is a rare form of autoimmune arthritis that develops after an infection, usually genital, urinary, or gastrointestinal. This type of arthritis mostly affect the joints in knees and feet, although other systems in the body may also be affected. Symptoms usually disappear within a year.

Rheumatoid Arthritis

RA is a systemic disease. It is characterized by inflammation in the lining or synovium of the joints, as well as inflammation in other systems in the body, including tendons, internal organs, and the vascular system. It often presents symmetrically. Nearly three times as many women as men have RA.


Scleroderma: causes a thickening or hardening of the connective tissue in the skin and internal organs. There are two main types of this disease. Localized scleroderma affects the skin only, whereas systemic scleroderma also impacts internal organs.

Sjögren’s Syndrome

Sjögren’s (pronounced SHOW-grins) mostly affects the glands that create tears and saliva, causing dry eyes and mouth. Some people may also experience joint pain, rashes, and inflammation in internal organs.

Still's Disease

In children, Still’s Disease is called systemic onset Juvenile Idiopathic Arthritis. Still’s is a rare in adults, but does occur. It usually starts with a salmon-coloured rash, followed by high fevers and joint pain.

Systemic Lupus Erythematosus
