Osteoarthritis – This is the most common type of arthritis, affecting an estimated 27 million adults in the United States. Osteoarthritis affects both the cartilage, which is the tissue that cushions the ends of bones within the joint, as well as the underlying bone. In osteo-arthritis, there is damage to the cartilage, which begins to fray and may wear away entirely. There is also damage to the bond stock of the joint. Osteoarthritis can cause joint pain and stiffness. Disability results most often when the disease affects the spine and the weight-bearing joints (the knees and hips).

Rheumatoid arthritis – This inflammatory disease of the immune system targets first the synovium, or lining of the joint, resulting in pain, stiffness, swelling, joint damage, and loss of function of the joints. Inflammation most often affects joints of the hands and feet and tends to be symmetrical (occurring equally on both sides of the body). This symmetry helps distinguish rheumatoid arthritis from other forms of the disease. About 0.6 percent of the U.S. population (about 1.3 million people) has rheumatoid arthritis.

Juvenile idiopathic arthritis – This disease is the most common form of arthritis in childhood, causing pain, stiffness, swelling, and loss of function of the joints. This condition may be associated with rashes or fevers and may affect -various parts of the body.

Fibromyalgia – Fibromyalgia is a chronic disorder that -causes pain throughout the tissues that support and move the bones and joints. Pain, stiffness, and localized tender points occur in the muscles and tendons, particularly those of the neck, spine, shoulders, and hips. Patients also may experience fatigue and sleep disturbances. Fibromyalia affects millions of adults in the United States.

Systemic lupus erythematosus – Systemic lupus erythematosus (also known as lupus or SLE) is an autoimmune disease in which the immune system harms the bodys own healthy cells and tissues. This can result in inflammation of and damage to the joints, skin, kidneys, heart, lungs, blood vessels, and brain. By conservative estimates, lupus affects about 150,000 people.

Scleroderma – Also known as systemic sclerosis, scleroderma means literally “hard skin.” The disease affects the skin, blood vessels, and joints. It may also affect internal organs, such as the lungs and kidneys. In scleroderma, there is an abnormal and excessive production of collagen (a fiber-like protein) in the skin and internal organs.

Spondyloarthropathies – This group of rheumatic diseases principally affects the spine. One common form ankylosing spondylitis also may affect the hips, shoulders, and knees. The tendons and -ligaments around the bones and joints become inflamed, resulting in pain and stiffness. Ankylosing spondylitis tends to affect people in late adolescence or early adulthood. Reactive arthritis, sometimes called Reiters syndrome, is another spondyloarthropathy. It develops after an infection involving the lower urinary tract, bowel, or other organ. It is commonly associated with eye problems, skin rashes, and mouth sores.

Infectious arthritis – This is a general term used to describe forms of arthritis that are caused by infectious agents, such as bacteria or viruses. Parvovirus arthritis and gonococcal arthritis are examples of infectious arthritis. Arthritis symptoms also may occur in Lyme disease, which is caused by a bacterial infection following the bite of certain ticks. In those cases of arthritis caused by bacteria, early diagnosis and treatment with antibiotics are crucial to removing the infection and minimizing damage to the joints.

Gout – This type of arthritis results from deposits of needle-like crystals of uric acid in the joints. The crystals cause episodic inflammation, swelling, and pain in the affected joint, which is often the big toe. An estimated 2.1 million Americans have gout.

Polymyalgia rheumatica – Because this disease involves tendons, muscles, ligaments, and tissues around the joint, symptoms often include pain, aching, and morning stiffness in the shoulders, hips, neck, and lower back. It is sometimes the first sign of giant cell arteritis, a disease of the arteries characterized by headaches, inflammation, weakness, weight loss, and fever.

Polymyositis – This rheumatic disease causes inflammation and weakness in the muscles. The disease may affect the whole body and cause disability.

Psoriatic arthritis – This form of arthritis occurs in some patients with psoriasis, a scaling skin disorder. Psoriatic arthritis often affects the joints at the ends of the fingers and toes and is accompanied by changes in the fingernails and toenails. Back pain may occur if the spine is involved.

Bursitis – This condition involves inflammation of the bursae, small, fluid-filled sacs that help reduce friction between bones and other moving structures in the joints. The inflammation may result from arthritis in the joint or injury or infection of the bursae. Bursitis produces pain and tenderness and may limit the movement of nearby joints.

Tendinitis (tendonitis) – This condition refers to inflammation of tendons (tough cords of tissue that connect muscle to bone) caused by overuse, injury, or a rheumatic condition. Tendinitis produces pain and tenderness and may restrict movement of nearby joints.

Sjogrens (SHOW-grens) syndrome – This is an autoimmune disease; that is, a disease in which the immune system turns against the bodys own cells. Normally, the immune system works to protect us from disease by destroying harmful invading organisms like viruses and bacteria. In the case of Sjogrens syndrome, disease-fighting cells attack various organs, most notably the glands that produce tears and saliva (the lacrimal and salivary glands). Damage to these glands causes a reduction in both the quantity and quality of their secretions. This results in symptoms that include dry eyes and dry mouth. In technical terms, the form of eye dryness associated with Sjogrens syndrome is called keratoconjunctivitis sicca, or KCS, and the symptoms of dry mouth are called xerostomia. Your doctor may use these terms when talking to you about Sjogrens syndrome.
