lupus

(lo͞o`pəs), noninfectious chronic disease in which antibodies in an individual's immune system attack the body's own substances. In lupus, known medically as lupus erythematosus, antibodies are produced against the individual's own cells, causing tissue inflammation and cell damage. Because the vascular and connective tissue of any body organ may be affected, various symptoms may result. Generalized symptoms include fever, weakness, weight loss, anemia, enlargement of the spleen, and a characteristic butterfly-shaped skin rash on the face. Heart, joint, and kidney disease are common (see nephritisnephritis
, inflammation of the kidney. The earliest finding is within the renal capillaries (glomeruli); interstitial edema is typically followed by interstitial infiltration of lymphocytes, plasma cells, eosinophils, and a small number of polymorphonuclear leukocytes.

). It is believed that the disease may be triggered by certain drugs or foreign proteins, exposure to ultraviolet radiation, or extreme stress. The disease, which may range from mild to fatal, occurs commonly in young women. It is treated with immunosuppressive drugsimmunosuppressive drug,
any of a variety of substances used to prevent production of antibodies. They are commonly used to prevent rejection by a recipient's body of an organ transplanted from a donor.

Lupus

(loo -pŭs) (Wolf) A constellation in the southern hemisphere near Centaurus, lying partly in the Milky Way, with several stars of 2nd magnitude. There are many naked-eye double stars and several globular and open star clusters. Abbrev.: Lup; genitive form: Lupi; approx. position: RA 15.3h, dec –45°; area: 334 sq deg.

Lupus

 

(or lupus vulgaris), the most severe and frequent form of skin tuberculosis. The causative agent of tuberculosis (mycobacterium tuberculosis) may invade the skin from without after an injury, but much more frequently it comes from internal organs and lymph nodes affected by tuberculosis. The course and symptoms of the disease vary greatly because they are determined by the virulence of the causative agent, point of entry, location of the disease, and general condition of the patient. The first symptom of the disease is a hyperemic spot that lightens when pressed; a tubercle soon develops. Under the pressure of a glass slide, it turns pale, and the lesion shows through as a pale yellow spot (the “apple jelly” phenomenon). Because the tissue in the affected area loses its elasticity, the tubercle is easily injured and bleeds readily. The tubercles gradually coalesce, forming large plaques. While the center of the plaque heals, forming a white scar as thin as cigarette paper (tubercles may again appear there), increasing numbers of fresh tubercles appear at the periphery. The epidermis covering the plaques thins and desquamates. Sometimes the tubercles become ulcerous; ulcers with a tubercular base may also develop. Lupus generally affects the face (nose, cheeks, ears), the extremities, and, less commonly, the trunk. The mucous membranes of the nose and mouth are often affected. Lupus occurs more frequently in children. The chronic course of the disease may result in disfigurement (eversion of the eyelids, narrowing of the mouth and nares, etc.) and occasionally in malignant degeneration. Thanks to modern methods of treatment and close follow-up of the patients, lupus has become less common and its prognosis is better. The disease is treated with a complex of antituberculous drugs, vitamin D2, multiple vitamins, tonics, physical therapy, sunbaths, and climatotherapy.
