TRIAL DESCRIPTION
Public title Isoniazid or Rifampicin and Isoniazid Preventive Therapy for children exposed to TB - the IRIPT trial
Official scientific title Isoniazid or Rifampicin and Isoniazid Preventive Therapy for children exposed to TB - the IRIPT trial
Brief summary describing the background
and objectives of the trial
Children<5 years of age exposed to TB at home, should receive Isoniazid Preventie Thearpy (IPT) according to WHO guidelines. An earlier study implemented 9 months IPT for exposed children in Bissau, but only 50% completed 6 months of continuous treatment. In the IRIPT study, we will compare 9 months of Isoniazid with 4 months of Rifampicin and Isoniazid, with adherence to therapy as primary endpoint. We also want to assess the mortality related to TB and TB exposure among children<15 in Bissau.
