Interleukin-12 as successful adjuvant in tuberculosis treatment. U. Greinert, M. Ernst, M. Schlaak, P. Entzian. #ERS Journals Ltd 2001. ABSTRACT: Interleukin-12 (IL-12) proved to be an effective and successful adjuvant to a standard antituberculotic medication in a patient suffering from progressive clinical tuberculosis (TB).IL-12 is a potent enhancer of interferon-c production which is necessary for killing intracellular bacteria like mycobacteria. This patient9s TB was progressive, although sensitivity to first-line antituberculotics was proven and medication was given as directly observed therapy over more than 8 months. The 3-month adjuvant therapy with IL-12 significantly and convincingly improved results.It is believed that this case, the first in the literature to describe adjuvant interleukin-12 therapy in tuberculosis, strongly encourages the study of adjuvant interleukin-12 therapy on a more systematic basis.
