How long does MB treatment last?
The current recommended length of treatment for MB patients, originally 24 months, is 12 months. No controlled trial data guided this decision, but the classification of MB patients had been widened, so some patients who would previously have received PB treatment for six months now receive MB treatment for 12 months. New evidence supports this decision on the duration of treatment. A study from Bangladesh has followed 1612 patients in two separate cohorts, treated with either six or 12 months of WHO-recommended MDT (monthly doses [supervised] of rifampin 600 mg and clofazimine 300 mg, daily dapsone, and daily clofazimine), for over seven years [30]. No patients have yet presented with a leprosy relapse. The rate of decline of the BI was similar in the two groups, and the loss to follow-up was 16.8% in both groups. The study continues to follow the patients. This study’s findings were supported by data from a randomized and controlled clinical trial (RCT) on U- MDT in Brazil.

Can MB leprae relapse?
Relapse, in MB leprosy, is defined as the multiplication of M. leprae, with an increase of at least 2+ over the previous value in the BI at any single site, usually with evidence of clinical deterioration (new skin patches or nodules and/or new nerve damage) [37]. Recognizing a relapse in PB leprosy is occasionally difficult, as symptoms may be similar to a Type 1 reaction. However, Type 1 reactions frequently occur and PB relapse is very rare. Administering a therapeutic test with corticosteroids to patients with new lesions may help distinguish between these two phenomena: a definite improvement within four weeks of corticosteroid therapy denotes a reversal reaction, and non-response to corticosteroids over the same period favors the diagnosis of a clinical relapse.
