Randomized Controlled Trial Multicenter Study
Levofloxacin Preventive Treatment in Children Exposed to MDR Tuberculosis.
Worldwide, approximately 2 million children younger than 15 years of age are infected with multidrug-resistant (MDR) Mycobacterium tuberculosis, with MDR tuberculosis developing in approximately 30,000 annually. Evidence from randomized, controlled trials on tuberculosis preventive treatment in persons exposed to MDR tuberculosis is lacking. ⋯ Although preventive treatment with levofloxacin led to a lower incidence of tuberculosis than placebo among children with household exposure to MDR tuberculosis, the difference was not significant.
