Many believe that the regular treatment for multibacillary (MB) leprosy cases could be shortened. A shorter treatment allowing uniformity in treatment for all cases renders case classification superfluous and therefore simplifies leprosy control.
To evaluate the association between treatment duration and the trend in bacteriological index (BI) decrease over time among patients given Uniform MDT (UMDT) compared to those given regular MDT (RMDT).
An open-label randomised clinical trial to compare the present routine treatment with one lasting six month. Patient intake was from March 2007 to February 2012. To evaluate the trend of BI as a function of time, a multilevel linear with mixed effects model was fixed to the two study groups and also four groups after stratification by BI, less than 3 and 3 or more.
The BI fall was higher among those taking RMDT, this difference however was not statistically significant.
The results presented here support the possibility of use of UMDT in the field, but further follow up is still needed for a final conclusion.
