Leprosy, Multibacillary: A form of LEPROSY classified by the World Health Organization for the purpose of treatment, based on clinical manifestations and skin smear results. Patients with multibacillary leprosy have six or more lesions with or without positive skin smear results for the causative agent MYCOBACTERIUM LEPRAE. Multibacillary leprosy encompasses borderline lepromatous, midborderline, and lepromatous leprosy.Leprosy: A chronic granulomatous infection caused by MYCOBACTERIUM LEPRAE. The granulomatous lesions are manifested in the skin, the mucous membranes, and the peripheral nerves. Two polar or principal types are lepromatous and tuberculoid.Leprostatic Agents: Substances that suppress Mycobacterium leprae, ameliorate the clinical manifestations of leprosy, and/or reduce the incidence and severity of leprous reactions.Mycobacterium leprae: A species of gram-positive, aerobic bacteria that causes LEPROSY in man. Its organisms are generally arranged in clumps, rounded masses, or in groups of bacilli side by side.Leprosy, Paucibacillary: A form of LEPROSY classified by the World Health Organization for the purpose of treatment, based on clinical manifestations and skin smear results. Patients with paucibacillary leprosy have fewer than six skin lesions with no causative agent MYCOBACTERIUM LEPRAE on any slit-skin smear testing. Paucibacillary leprosy encompasses indeterminate, borderline tuberculoid, and tuberculoid leprosy.Leprosy, Lepromatous: A chronic communicable infection which is a principal or polar form of LEPROSY. This disorder is caused by MYCOBACTERIUM LEPRAE and produces diffuse granulomatous skin lesions in the form of nodules, macules, or papules. The peripheral nerves are involved symmetrically and neural sequelae occur in the advanced stage.Leprosy, Borderline: A form of LEPROSY in which there are clinical manifestations of both principal types (lepromatous and tuberculoid). The disease may shift toward one of these two polar or principal forms.Leprosy, Tuberculoid: A principal or polar form of LEPROSY in which the skin lesions are few and are sharply demarcated. Peripheral nerve involvement is pronounced and may be severe. Unlike lepromatous leprosy (LEPROSY, LEPROMATOUS), the lepromin test is positive. Tuberculoid leprosy is rarely a source of infection to others.Bible: The book composed of writings generally accepted by Christians as inspired by God and of divine authority. (Webster, 3d ed)Clofazimine: A fat-soluble riminophenazine dye used for the treatment of leprosy. It has been used investigationally in combination with other antimycobacterial drugs to treat Mycobacterium avium infections in AIDS patients. Clofazimine also has a marked anti-inflammatory effect and is given to control the leprosy reaction, erythema nodosum leprosum. (From AMA Drug Evaluations Annual, 1993, p1619)Erythema Nodosum: An erythematous eruption commonly associated with drug reactions or infection and characterized by inflammatory nodules that are usually tender, multiple, and bilateral. These nodules are located predominantly on the shins with less common occurrence on the thighs and forearms. They undergo characteristic color changes ending in temporary bruise-like areas. This condition usually subsides in 3-6 weeks without scarring or atrophy.Glycolipids: Any compound containing one or more monosaccharide residues bound by a glycosidic linkage to a hydrophobic moiety such as an acylglycerol (see GLYCERIDES), a sphingoid, a ceramide (CERAMIDES) (N-acylsphingoid) or a prenyl phosphate. (From IUPAC's webpage)Antigens, Bacterial: Substances elaborated by bacteria that have antigenic activity.Skin: The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.BrazilDrug Therapy, Combination: Therapy with two or more separate preparations given for a combined effect.Antibodies, Bacterial: Immunoglobulins produced in a response to BACTERIAL ANTIGENS.LeprominSensitivity and Specificity: Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed)Armadillos: Burrowing, chiefly nocturnal mammals of the family Dasypodidae having bodies and heads encased in small bony plates. They are widely distributed in the warmer parts of the Americas.Dapsone: A sulfone active against a wide range of bacteria but mainly employed for its actions against MYCOBACTERIUM LEPRAE. Its mechanism of action is probably similar to that of the SULFONAMIDES which involves inhibition of folic acid synthesis in susceptible organisms. It is also used with PYRIMETHAMINE in the treatment of malaria. (From Martindale, The Extra Pharmacopoeia, 30th ed, p157-8)
