Seminar | TB preventive therapy: a new era is emerging

Abstract: TB infection is the reservoir of the TB epidemic. The burden of TB infection has recently been re-estimated at approximately 23%, amounting to approximately 1.7 billion people infected with TB globally. The uptake of isoniazid preventive therapy globally among people living with HIV and household contacts has been very poor. Recently published randomised clinical trials show that TB preventive therapy with antiretroviral therapy saves lives. Furthermore, recently completed clinical trials provide evidence for novel, short and ultra-short course, rifamycin based TB preventive therapy regimens. The World Health Organisation has recently issued integrated guidance for the programmatic management of latent TB infection, which recommends short-course regimens such as high-dose isoniazid and rifapentine weekly for 12 weeks in high-burden countries. Interventions to address market and public health barriers to the scale up of TB preventive therapy, particularly rifapentine based regimens, will be discussed. Opportunities for further innovation in TB preventive therapy will be presented.
