Additionally, it presents a wide spectrum of clinical manifestations, which are dependent on the interaction between M. leprae and host, and are related to the degree of immunity to the bacillus. [ Links ], 7. Basic concepts in medical informatics. However, given the severe nature of lepromatous leprosy, a skin test is unnecessary, and the definitive test, a biopsy, readily reveals the bacterium within lesions as well as the characteristic histopathology of HD. The low agreement observed can be related to the variability of the results in the calculation of the total area, which varied between 0 and 79 square millimeters (mm2), while the measurement by the diameter generally vary from 0 to 10 millimeters. 1972;46:821-6.

There are two types of lepromin antigen in use that differ in the method of preparation. The injection site is labeled and examined at 48hours and 21 days later to see if there is a reaction. This is because an effective immune response to the bacterium is a result of a cellular immune response (T-cell mediated) rather than a humoral response (B-cell/antibody). Clin Microbiol Infect. People who don't have clinical leprosy (Hansen's disease, or HD) may have little or no skin reaction to the antigen, or may have a strong reaction to it.

The intraclass correlation coefficient indicated a low (0.219) but significant agreement between the two measurements. In order to evaluate the agreement between the area of the Mitsuda test obtained from dermatoscopy and the area obtained from mathematical calculations, the Intraclass Correlation Coefficient was used because it is a numerical variable. 2019 Nov 16;17:100134. doi: 10.1016/j.jctube.2019.100134. 1 Lepromatous HD, the more severe and disfiguring form is a result of the patient's immune response being mainly humoral in nature. -.
