Mycobacterium leprae infection treatment

Not all mycobacterial infections are caused by Mycobacterium tuberculosis or Mycobacterium leprae. These atypical mycobacteria require treatment with secondary medications as well as other chemotherapeutic agents. For example, Mycobacterium marinum causes skin granulomas, and effective drugs in the treatment of the infection are rifampin or minocycline. Mycobacterium fortuitum causes skin ulcers, and the medications recommended for treatment are ethambutol, cycloserine, and rifampin in combination with amikacin. 

Clarithromycin or azithromycin is recommended as first-line therapy for prophylaxis and treatment of disseminated infection caused by M. avium-intracellulare in AIDS patients and for treatment of pulmonary disease in non-HIV-infected patients. Azithromycin (1.2 g once weekly) or clarithromycin (500 mg twice daily) is recommended for primary prevention for AIDS patients with fewer than 50 CD cells per mm. Single-agent therapy should not be used for treatment of active disease or for secondary prevention in AIDS patients. Clarithromycin (500 mg twice daily) plus ethambutol (15 mg/kg once daily) with or without rifabutin is an effective combination regimen. Azithromycin (500 mg once daily) may be used instead of clarithromycin, but clarithromycin appears to be slightly more efficacious. Clarithromycin also has been used with minocychne for the treatment of Mycobacterium leprae in lepromatous leprosy.
