A total of 529 weak or non-reactors to M. leprae, including Mitsuda-negative contacts and patients with leprosy, were vaccinated once or repeatedly, as necessary, with a mixture of 6 x 10(8) purified, heat-killed M. leprae and 0.01 mg to 0.2 mg of viable BCG. Clinical, histopathological and immunological criteria were used to evaluate the response of these individuals. Clinical changes, including sharper definition of borders and progressive flattening and regression of lesions, were observed in 57% of the active LL cases and 76% of the active BL cases. Histopathological study revealed infiltration of the lesions by mononuclear cells, appearance of epithelioid differentiation, and fragmentation of the microorganisms. Delayed-type skin tests with soluble antigen from purified M. leprae became positive in significant numbers of each group studied. These results demonstrate the efficacy of combined immunotherapy in low-resistance forms of leprosy and potential utility in the immunoprophylaxis of the disease.

Background: People with disabilities due to neglected tropical diseases (NTDs), such as leprosy and lymphatic filariasis (LF), often encounter situations of stigma and discrimination that significantly impact their mental wellbeing. Mental wellbeing services are often not available at the peripheral level in NTD-endemic countries, and there is a need for such services. Basic psychological support for persons with NTDs (BPS-N) from peers is an important potential solution for addressing mental wellbeing problems.
