The list of types of Leprosy mentioned in various sources includes: Paucibacillary Hansen's disease Multibacillary Hansen's disease Types discussion: Patients are classified as having paucibacillary or multibacillary Hansen's disease. Antibiotics are used by doctors to treat the infection. The time period between being exposed and the appearance of symptoms is known as the incubation period. Leprosy is also known as Hansen's disease, after the scientist who discovered M. leprae in 1873. The four strains of M. leprae are based in specific geographic regions. Leprosy is a chronic granulomatous infection. BT leprosy in type 1 reaction presenting with ulnar nerve abscess and subsequent deformity in the form of ulnar clawing. Tuberculoid leprosy is the more benign type, even though it is accompanied by nerve involvement, which leads to numbness (usually of the extremities), contractures, and ulceration. There are some anti-inflammatory drugs that are used to control nerve pain and severe damage caused by leprosy. The history of leprosy was traced by geneticists in 2005 through its origins and worldwide distribution using comparative genomics.They determined that leprosy originated in East Africa or the Near East and traveled with humans along their migration routes, including those of trade in goods and slaves.

Skin biopsies, nasal discharges, scrapings from the nasal mucosa and slit-skin smears which are prepared by making superficial incisions in the skin, scraping out some tissue fluid and cells. This infection heals on its own, or it can persist and progress to a more severe form. When autocomplete results are available use up and down arrows to review and enter to select. They do not indicate disease progression or treatment failure, and are classified as type 1 or type 2. Some leprologists reserve the term ENL for the skin lesions associated with the systemic illness of T2R; however, in this chapter, the term ENL will be used to refer to the whole syndrome. The skin smears are collected from the leprous lesions, such as nodules, thick papules, and areas of infiltration. Classification of the disease is important to determine prognosis, patients at higher risk of reactions, and nerve damage, as well as select appropriate treatment. There are three systems for classifying leprosy. There are six types of leprosy and are mainly classified based on the severity of symptoms, which include- Intermediate, Tuberculoid, Borderline tuberculoid, Mid-borderline, Borderline and Lepromatous leprosy. Leprosy or Leprosy patients can be classified using two systems: the Ridley–Jopling system and the WHO system.

Leprosy (a.k.a: Hansen’s Disease) is a chronic and contagious disease caused by bacteria called Mycobacterium Leprae.Due to high rate of transmission, leprosy stands as a major health problem in many countries. 4 Vasculonecrotic reactions (Lucio leprosy phenomenon) in leprosy are much less common. Leprosy is curable and treatment in the early stages can prevent disability. Leprosy is a chronic infectious disease of humans caused by the bacteria Mycobacterium leprae. The disease may present different clinical forms depending on the immunological status of the host. Leprosy comes in two main forms, tuberculoid and lepromatous disease. The skin may feel numb because of the damaged nerve underneath. Leprosy is a slowly developing, progressive disease that damages the skin and nervous system. Leprosy: Types list.

However, in practice, most programmes use clinical criteria for classifying and deciding the appropriate treatment regimen for individual patients, particularly in view of the non-availability or non-dependability of the skin-smear services. Leprosy is classified into several types based on the bacterial load present in the lesions, the extent of skin and nerve involvement and based on the presence of deformities. It is considered a more severe type of disease with many lesions with bacteria. Infection can lead to damage of the nerves, respiratory tract, skin, and eyes. Types of leprosy. Leprosy reactions are produced by changes in the body's immunologic response to the infection and often lead to nerve damage. That’s one of the reasons why diagnosis can be so difficult.

Paucibacillary Leprosy: There will be 1 to 5 skin lesions and only one nerve involvement. In cases of patches, the samples are obtained from the edge of the lesion rather than from the center. LEPRA REACTIONS During the course of leprosy, immunological mediated episodes of acute or subacute inflammation known as reaction may occur. Leprosy is also transmitted through insects.

In the classification based on skin smears, patients showing negative smears at all sites are grouped as paucibacillary leprosy (PB), while those showing positive smears at any site are grouped as having multibacillary leprosy (MB). Clinical, Bacteriologic, Pathologic, and Immunologic Spectrum of Leprosy Feature Tuberculoid (TT, BT) Leprosy Borderline (BB, BL) Leprosy Lepromatous (LL) Leprosy Skin lesion One or a few sharply defined annular asymmetric macules or plaques with a tendency toward central clearing, elevated borders Intermediate between BT- and LL-type lesions; ill-defined plaques with an occasional … Let us know more about each of them in detail. In tuberculoid leprosy the skin lesions are small and contain few bacteria in each. In the tuberculoid form of the disease the skin lesions appear as light red or purplish spots. An infection with Mycobacterium leprae or M. lepromatosis bacteria causes leprosy. Leprosy can be considered 2 connected diseases that primarily affect superficial tissues, especially the skin and peripheral nerves. The clinical range from tuberculoid to lepromatous leprosy is a result of variation in the cellular immune response to the mycobacterium. Your email address will not be published.
