Gaensbauer J, et al. - This study was initiated in order to determine the efficacy of a 4-month regimen of daily rifampin (4R) for the treatment of pediatric latent tuberculosis infection (LTBI). The tendency for completion of LTBI treatment was substantially greater among pediatric subjects using a 4R than with a 9-month isoniazid regimen. A rise could be noted in the efficacy of tuberculosis prevention along with a decreased demand on public health resources due to better completion rates of 4R.
