* Connective tissue disorders (collagen vascular disease) are defined as a group of acquired disorders that have the commonality of immunologic and inflammatory changes in small blood vessels and connective tissue.

* Common features include arthritis, skin lesions, iritis and episcleritis, pericarditis, pleuritis, subcutaneous nodules, myocarditis, vasculitis, and nephritis.

* Lupus is a chronic autoimmune disease resulting in inflammation and tissue damage.

* The exact cause is unknown; however, current research points to interrelated immunologic, environmental, hormonal, and genetic factors.

* Lupus strikes women 10 to 15 times more frequently than men, and occurs most often during childbearing years (see Figure 1).

* Types include cutaneous lupus erythematosus, systemic lupus erythematosus, drug-induced lupus erythematosus, and neonatal lupus erythematosus.

* Diagnosis includes a complete history and physical, including a full-skin assessment. Currently, there is no single definitive laboratory test for lupus.

* Prevention is key to minimizing symptoms, reducing inflammation, and maintaining normal bodily functions.

* Scleroderma (systemic sclerosis) is a chronic, often progressive autoimmune disease, which can cause thickening and tightening of the skin by excessive collagen production.

* Scleroderma varies widely in severity; in some cases, internal organs such as lungs, heart, kidneys, esophagus, and GI tract are seriously damaged (see Figures 2-3).

* The exact cause(s) of scleroderma is unknown, but research is pointing to a “susceptible gene.”

* Classifications of scleroderma include localized scleroderma, systemic scleroderma (also called progressive systemic sclerosis), and scleroderma-related disorders.

* Localized scleroderma affects the collagen-producing cells in limited skin areas and usually spares the internal organs and blood vessels.

* In systemic scleroderma, the immune system causes damage to small blood vessels and the collagen-producing cells throughout the body.

* Scleroderma-related disorders occur in patients with other autoimmune disorders and may be referred to as an “overlap syndrome.”

* Diagnosis includes a detailed history of signs/symptoms during general systems review that prompted medical services which may indicate progression and severity of disease process.

* There is no cure for scleroderma. Treatment plans are individualized to each patient’s type and severity of symptoms.

* Inflammatory myopathies are a group of muscle diseases characterized by inflammation of connective tissue and muscle fibers which can cause extensive necrosis and destruction of the muscle fibers.

* The inflammatory myopathies are dermatomyositis, juvenile dermatomyositis, polymyositis, and inclusion body myositis. Each is unique in its development and treatment.

* Inflammatory myopathies are designated as autoimmune diseases because of the presence of autoantibodies in the serum of those affected.

* There is no known cure for inflammatory myopathies.

* High doses of immunosuppressants and/or steroids have been effective for many patients.
