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: 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.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, 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.Leprostatic Agents: Substances that suppress Mycobacterium leprae, ameliorate the clinical manifestations of leprosy, and/or reduce the incidence and severity of leprous reactions.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, 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.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.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.

Its intermediate host and vector is the blackfly or buffalo gnat.Onchocerciasis: Infection with nematodes of the genus ONCHOCERCA. Characteristics include the presence of firm subcutaneous nodules filled with adult worms, PRURITUS, and ocular lesions.Onchocerca: A genus of parasitic nematodes whose organisms live and breed in skin and subcutaneous tissues. Onchocercal microfilariae may also be found in the urine, blood, or sputum.Microfilaria: The prelarval stage of Filarioidea in the blood and other tissues of mammals and birds.

  • Background: Between 20 and 30 bacteriologically confirmed cases of leprosy are diagnosed each year at the French National Reference Center for mycobacteria. (ebscohost.com)
  • Current evidence suggests that specialized pro-resolving lipid mediators (SPMs) are involved in the down-modulation of the innate and adaptive immune response against M. leprae and that alteration in the homeostasis of pro-inflammatory lipid mediators versus SPMs is associated with dramatic shifts in the pathogenesis of leprosy. (frontiersin.org)
  • Leprosy is well known for its bi-polarization of the immune response, and it is established that the nature and magnitude of the host immune response against M. leprae are critical factors for the pathogenesis of leprosy and its varied clinical manifestations. (frontiersin.org)
  • There is considerable clinical variability among leprosy patients once M. leprae infection evokes distinct T cell responses in humans. (frontiersin.org)

  • These data suggest that the protective effect of LRRK2 variant p.M2397T on leprosy might be mediated by increasing immune response and decreasing neurotoxicity after M. leprae loading. (sigmaaldrich.com)
  • This result was consistent with the hypothesized "two-step model for the development of leprosy, in which successful infection of M. leprae is first established in genetically predisposed persons, and the subsequent clinical manifestation of disease is influenced by other host factors and environmental factors," Zhang's group wrote. (medpagetoday.com)
  • The immune response to M. leprae is determined by host genetics, resulting in paucibacillary (PB) and multibacillary (MB) leprosy associated with dominant cellular or humoral immunity, respectively. (nature.com)
  • This spectral pathology of leprosy compels detection of immunity to M. leprae to be based on multiple, diverse biomarkers. (nature.com)
  • The test protocol presented in this study merging detection of innate, adaptive cellular as well as humoral immunity, thus provides a convenient tool to measure specific biomarker profiles for M. leprae infection and leprosy utilizing a field-friendly technology. (nature.com)
  • These hurdles contributed to the current lack of tests for detection of asymptomatic M. leprae infection and diagnosis of early stage leprosy 11 . (nature.com)
  • Clinical manifestations closely parallel cellular immunity to M. leprae such that leprosy presents as a characteristic spectrum ranging from tuberculoid (TT) or paucibacillary (PB) leprosy to lepromatous (LL) or multibacillary (MB) leprosy 14 . (nature.com)
  • Our primary aim was to investigate the utility of the surface expression of neutrophil IL-10R1 as an ENL biomarker and, secondarily, to evaluate whether leprosy or healthy M. leprae-stimulated neutrophils produce cytokines and are able to respond to IL-10. (bvsalud.org)
  • Ideally, diagnostic reagents should detect all forms of leprosy, ranging from the tuberculoid or paucibacillary (PB) form, characterized by strong cell-mediated immunity (CMI) to M. leprae , to the lepromatous or multibacillary (MB) form, with weak CMI to M. leprae and a high level of antibody formation ( 2 ). (asm.org)
  • This implies that a combination of tests will be required for the efficient detection of leprosy, i.e., a specific skin test for the detection of CMI to M. leprae and a serological assay for the detection of anti- M. leprae antibodies. (asm.org)
  • Previous studies have established that assays detecting the monoclonal antibody (MAb) MLO4 epitope of the M. leprae 35-kDa protein using M. leprae sonicate (MLS) are specific and sensitive for the serodiagnosis of leprosy. (asm.org)
  • Therefore, we have assessed the suitability of the purified recombinant M. leprae 35-kDa protein for the routine serological diagnosis of leprosy. (asm.org)
  • We found that fluorescent stain was superior to modified Fite- faraco in detecting leprae bacilli in tissue sections particularly in paucibacillary cases where bacillary load is much low. (ispub.com)
  • Those peptides that provide specific responses in leprosy patients from an endemic setting could potentially be developed into a rapid diagnostic test for the early detection of M. leprae infection and epidemiological surveys of the incidence of leprosy, of which little is known. (epfl.ch)
  • Even this was too complicated for field workers, so in 1982 a WHO Expert Committee on Leprosy simplified the system based on the number of M. leprae in the patient. (isradiology.org)
  • If the skin smears are negative for M. leprae , the patient is classified as paucibacillary (PB). (isradiology.org)
  • Here we investigated the possible influence of M. leprae/T. gondii co-parasitism on the manifestation of leprosy and its clinical forms. (bvsalud.org)
  • Leprosy was clinically diagnosed and specific anti- M. leprae antibodies were measured using ELISA. (biomedcentral.com)
  • The main research question of this study was to test which correlation structure (genetic, household or spatial) gives the best explanation for the distribution of leprosy patients and persons harbouring specific anti- M. leprae antibodies (seropositive persons) in our study population. (biomedcentral.com)
  • With a goal of developing such tests, antibody responses of leprosy patients to M. leprae proteins and lipids have been extensively investigated, with M. leprae -specific phenolic glycolipid I (PGL-I) antigen representing the most thoroughly investigated to date. (springer.com)
  • The diagnosis of leprosy is often complicated by what have been defined as the 'spectral' manifestations of the disease, which are due to the variability in the type and strength of the body's immune response (see Chapter 6.2 ) to M. leprae . (internationaltextbookofleprosy.org)
  • Sign of leprosy can vary depending on the individual's immune response to M. leprae. (bestonlinemd.com)
