Connective Tissue Disease Glossary of Terms

The following are health and medical definitions of terms that appear in the Connective Tissue Disease article.

Abnormal: Not normal. Deviating from the usual structure, position, condition, or behavior. In referring to a growth, abnormal may mean that it is cancerous or premalignant (likely to become cancer).

Aorta: The largest artery in the body, the aorta arises from the left ventricle of the heart, goes up (ascends) a little ways, bends over (arches), then goes down (descends) through the chest and through the abdomen to where ends by dividing into two arteries called the common iliac arteries that go to the legs.
See the entire definition of Aorta

Arthritis: Inflammation of a joint. When joints are inflamed they can develop stiffness, warmth, swelling, redness and pain. There are over 100 types of arthritis. (see osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, lupus, gout, pseudogout).

Autoimmunity: A misdirected immune response that occurs when the immune system goes awry and attacks the body itself.
See the entire definition of Autoimmunity

Circulation: The movement of fluid in a regular or circuitous course. Although the noun "circulation" does not necessarily refer to the circulation of the blood, for all practical purposes today it does. Heart failure is an example of a problem with the circulation.

Collagen: Collagen is the principal protein of the skin, tendons, cartilage, bone and connective tissue.

Connective tissue: A material made up of fibers forming a framework and support structure for body tissues and organs. Connective tissue surrounds many organs. Cartilage and bone are specialized forms of connective tissue. All connective tissue is derived from mesoderm, the middle germ cell layer in the embryo.

Connective tissue disease: A disease (autoimmune or otherwise) that attacks the collagen or other components of connective tissue, such as lupus.

Dermatomyositis: A chronic inflammatory disease of skin and muscle which is associated with patches of slightly raised reddish or scaly rash. The rash can be on the bridge of the nose, around the eyes, or on sun-exposed areas of the neck and chest. Classically, however, it is over the knuckles. When the characteristic inflammation of the muscle (myositis) occurs without skin disease, the condition is referred to as polymyositis.
See the entire definition of Dermatomyositis

Diagnosis: 1 The nature of a disease; the identification of an illness. 2 A conclusion or decision reached by diagnosis. The diagnosis is rabies. 3 The identification of any problem. The diagnosis was a plugged IV.
See the entire definition of Diagnosis

Elastin: A protein that coil and recoils like a spring within the elastic fibers of connective tissue and accounts for the elasticity of structures such the skin, blood vessels, heart, lungs, intestines, tendons, and ligaments. Elastin functions in connective tissue together with collagen. Whereas elastin provides elasticity, collagen provides rigidity to connective tissue. Elastin is normally no longer made after puberty and aging begins. Also called elasticin.

Gene: The basic biological unit of heredity. A segment of deoxyribonucleic acid (DNA) needed to contribute to a function.
See the entire definition of Gene

Genetic: Having to do with genes and genetic information.

Heart: The muscle that pumps blood received from veins into arteries throughout the body. It is positioned in the chest behind the sternum (breastbone; in front of the trachea, esophagus, and aorta; and above the diaphragm muscle that separates the chest and abdominal cavities. The normal heart is about the size of a closed fist, and weighs about 10.5 ounces. It is cone-shaped, with the point of the cone pointing down to the left. Two-thirds of the heart lies in the left side of the chest with the balance in the right chest.
See the entire definition of Heart

Immune: Protected against infection. The Latin immunis means free, exempt.

Immune system: A complex system that is responsible for distinguishing us from everything foreign to us, and for protecting us against infections and foreign substances. The immune system works to seek and kill invaders.
See the entire definition of Immune system

Inflammation: A basic way in which the body reacts to infection, irritation or other injury, the key feature being redness, warmth, swelling and pain. Inflammation is now recognized as a type of nonspecific immune response.
See the entire definition of Inflammation

Inheritance: Not something that is contained in a will, but rather a gene, chromosome or genome that is transmitted from parent to child.
See the entire definition of Inheritance

Lungs: The lungs are a pair of breathing organs located with the chest which remove carbon dioxide from and bring oxygen to the blood. There is a right and left lung.

Lupus: A chronic inflammatory condition caused by an autoimmune disease. An autoimmune disease occurs when the body's tissues are attacked by its own immune system. Patients with lupus have unusual antibodies in their blood that are targeted against their own body tissues.
See the entire definition of Lupus

Pathology: The study of disease. Pathology has been defined as "that branch of medicine which treats of the essential nature of disease." The word "pathology" comes from the Greek words "pathos" meaning "disease" and "logos" meaning "a treatise" = a treatise of disease. The word "pathology" is sometimes misused to mean disease as, for example, "he didn't find any pathology" (meaning he found no evidence of disease). A medical doctor that specializes in pathology is called a pathologist. Pathologists are experts at interpreting microscopic views of body tissues.

Polymyositis: A chronic inflammatory disease of muscle that begins when white blood cells, the immune cells of inflammation, spontaneously invade muscles, especially the muscles closest to the trunk or torso, resulting in sometimes severe muscle pain, tenderness and weakness.
See the entire definition of Polymyositis

Predispose: To make more likely or render susceptible. Smoking predisposes to a number of diseases, including esophageal cancer.

Protein: A large molecule composed of one or more chains of amino acids in a specific order determined by the base sequence of nucleotides in the DNA coding for the protein.
See the entire definition of Protein

Rheumatoid arthritis: An autoimmune disease which causes chronic inflammation of the joints, the tissue around the joints, as well as other organs in the body. Autoimmune diseases occur when the body tissues are mistakenly attacked by its own immune system. The immune system is a complex organization of cells and antibodies designed normally to "seek and destroy" invaders of the body, particularly infections. Patients with these diseases have antibodies in their blood which target their own body tissues, where they can be associated with inflammation. Because it can affect multiple other organs of the body, rheumatoid arthritis is referred to as a systemic illness and is sometimes called rheumatoid disease. While rheumatoid arthritis is a chronic illness (meaning it can last for years) patients may experience long periods without symptoms.
See the entire definition of Rheumatoid arthritis

Scleroderma: A disease of connective tissue with the formation of scar tissue (fibrosis) in the skin and sometimes also in other organs of the body.
See the entire definition of Scleroderma

Skeleton: The skeleton is composed of bones and is the framework of the body.

Syndrome: A set of signs and symptoms that tend to occur together and which reflect the presence of a particular disease or an increased chance of developing a particular disease.
See the entire definition of Syndrome

Systemic: Affecting the entire body. A systemic disease such as diabetes can affect the whole body. Systemic chemotherapy employs drugs that travel through the bloodstream and reach and affect cells all over the body.

Vascular: Relating to the blood vessels of the body. The blood vessels of the body, as a group, are referred to as the vascular system.

  • Related Diseases & Conditions

    • Rheumatoid Arthritis
      • Rheumatoid arthritis is an autoimmune disease that causes chronic inflammation of the joints, the tissue around the joints, as well as other organs in the body. Because it can affect multiple other organs of the body, rheumatoid arthritis is referred to as a systemic illness and is sometimes called rheumatoid disease.
    • Sjogren's Syndrome
      • Sjögren's syndrome is an autoimmune disease involving the abnormal production of extra antibodies that attack the glands and connective tissue. Sjögren's syndrome with gland inflammation (resulting dry eyes and mouth, etc.) that is not associated with another connective tissue disease is referred to as primary Sjögren's syndrome. Sjögren's syndrome that is also associated with a connective tissue disease, such as rheumatoid arthritis, systemic lupus erythematosus, or scleroderma, is referred to as secondary Sjögren's syndrome. Though there is no cure for Sjögren's syndrome, the symptoms may be treated by using lubricating eye ointments, drinking plenty of water, humidifying the air, and using glycerin swabs. Medications are also available to treat dry eye and dry mouth.
    • Lupus
      • Systemic lupus erythematosus is a condition characterized by chronic inflammation of body tissues caused by autoimmune disease. Lupus can cause disease of the skin, heart, lungs, kidneys, joints, and nervous system. When only the skin is involved, the condition is called discoid lupus. When internal organs are involved, the condition is called systemic lupus erythematosus (SLE).
    • Psoriatic Arthritis
      • Psoriatic arthritis is a disease that causes skin and joint inflammation. Symptoms include painful, stiff, and swollen joints, tendinitis, and organ inflammation. Treatment involves antiinflammatory medications and exercise.
    • Scleroderma
      • Scleroderma is an autoimmune disease of the connective tissue. It is characterized by the formation of scar tissue (fibrosis) in the skin and organs of the body, leading to thickness and firmness of involved areas. Scleroderma is also referred to as systemic sclerosis, and the cause is unknown. Treatment of scleroderma is directed toward the individual features that are most troubling to the patient.
    • Henoch-Schonlein Purpura
      • Henoch-Schonlein Purpura (HSP or anaphylactoid purpura), a type of blood vessel inflammation, results in rash, arthritis, and occasional abdominal cramping. HSP often resolves on its own. Joint pain may be treated with anti-inflammatory and cortisone medications.
    • Marfan Syndrome
      • Marfan syndrome is hereditary condition affecting connective tissue. A person with Marfan syndrome may exhibit the following symptoms and characteristics: dislocation of one or both lenses of the eye; a protruding or indented breastbone; scoliosis; flat feet; aortic dilatation; dural ectasia; stretch marks; hernia; and lung collapse. Though there is no cure for Marfan syndrome, there are treatments that can minimize and sometimes prevent some complications.
    • Polymyositis
      • Polymyositis is a disease of the muscle featuring inflammation of the muscle fibers. It results in weakness of the muscles which can be severe and when associated with skin rash, is referred to as dermatomyositis. Although the cause of this disease is unknown, diagnosis includes physical examination of muscle strength, blood tests for muscle enzymes, electrical tests of muscle and nerves, and conformation by a muscle biopsy. Treatment of Polymyositis and Dermatomyositis includes high doses of cortisone-related medications, immune suppression, and physical therapy.
    • Ehlers-Danlos Syndrome
      • Ehlers-Danlos syndromes are genetic disorders that include symptoms such as loose joints, tissue weakness, easy bruising, and skin that stretches easily. There are seven types of Ehlers-Danlos syndromes: Classical type, Hypermobility type, Vascular type, Kyphoscoliosis type, Arthrochalsia type, Dermatosparaxis type, and Tenascin-X Deficient type. Treatment for Ehlers-Danlos syndromes depends on which symptoms are present.
    • Kawasaki Disease
      • Kawasaki disease is a rare children's disease characterized by a fever that lasts more than five days and at least four of the following five symptoms are present: rash, swollen neck lymph gland, red tongue, swelling or redness of the hands or feet, and conjunctivitis. High doses of aspirin are used to treat Kawasaki disease. Cortisone and antiinflammatory drugs may also be used during treatment.
    • Wegener's Granulomatosis
      • Wegener's granulomatosis, a condition that usually affects young or middle-aged adults, is an inflammation of the arteries supplying blood to the sinuses, lungs, and kidneys. Symptoms of Wegener's granulomatosis include bloody sputum, fatigue, weight loss, joint pain, sinusitis, shortness of breath, and fever. Wegener's granulomatosis may be fatal within months without treatment. Treatment aims to stop inflammation with high doses of prednisone and cyclophosphamide.
    • Still's Disease
      • Still's disease (Systemic-Onset Juvenile Rheumatoid Arthritis) is a disorder characterized by inflammation with high fever spikes, fatigue, salmon-colored rash and/or arthritis. Though there have been several theories regarding the cause(s) of Still's disease, the cause is not yet known. Many symptoms of Still's disease are often treatable with anti-inflammatory drugs.
    • Mixed Connective Tissue Disease
      • Connective tissue diseases are disorders featuring abnormalities involving the collagen and elastin. Connective tissue diseases that are strictly inheritable include Marfan syndrome and Ehlers-Danlos syndrome. The classic immune-related connective tissue diseases include systemic lupus erythematosus, rheumatoid arthritis, scleroderma, polymyositis, and dermatomyositis. Treatment is often directed at suppressing the inflammation present in the tissues by using anti-inflammatory and immunosuppressive medications.
    • Reactive Arthritis
      • Reactive arthritis is a chronic, systemic rheumatic disease characterized by three conditions, including conjunctivitis, joint inflammation, and genital, urinary or gastrointestinal system inflammation. Inflammation leads to pain, swelling, warmth, redness, and stiffness of the affected joints. Non-joint areas may experience irritation and pain. Treatment for reactive arthritis depends on which area of the body is affected. Joint inflammation is treated with antiinflammatory medications.
    • Takayasu Disease
      • Takayasu disease (also referred to as Takayasu arteritis) is a chronic inflammation of the aorta and it's branch arteries. Takayasu disease is most common of Women of Asian descent and usually begins between 10 and 30 years of age. Symptoms include: painful extremities, dizziness, headaches, chest and abdominal pain, and a low-grade fever. Treatment for Takayasu disease includes cortisone medication to suppress the inflammation.
    • Polyarteritis Nodosa
      • Polyarteritis nodosa is a rare autoimmune disease characterized by spontaneous inflammation of the arteries of the body. The most common areas of involvement include the muscles, joints, intestines (bowels), nerves, kidneys, and skin. Poor function or pain in any of these organs can be a symptom. Polyarteritis nodosa is most common in middle age persons. Polyarteritis is a serious illness that can be fatal. Treatment is focused on decreasing the inflammation of the arteries by suppressing the immune system.
