Isoniazid preventive therapy (IPT) and TB infection in intrahousehold contacts: Results from a cohort in Peru

Although IPT is known to protect TST positive children from TB disease progression, here we find that IPT is associated with a modestly higher rate of TST conversion. This finding raises the possibility that IPT enhances the immune response to TB infection, paradoxically leading to increased TST induration size at the same time that it protects against TB disease progression.
