    Abstract:
    SETTING: Pediatric multidrug-resistant tuberculosis (MDR-TB) is complicated by difficult diagnosis, complex treatment, and high mortality. In South Africa, these challenges are amplified by human immunodeficiency virus (HIV) co-infection; however, evidence on treatment outcomes among co-infected children is limited. OBJECTIVE: Using conventional and new pediatric definitions, to describe treatment outcomes and identify risk factors for unfavorable outcome and mortality in children aged <15 years with MDR-TB or extensively drug-resistant TB (XDR-TB) in KwaZulu-Natal, South Africa. DESIGN: Retrospective cohort study in a regional TB referral hospital. RESULTS: From January 2009 to June 2010, 84 children (median age 8 years, IQR 4-12) with MDR-TB (n = 78) or XDR-TB (n = 6) initiated treatment. Sixty-four (77%) were HIV-positive and 62 (97%) received antiretroviral therapy. Sixty-six (79%) achieved favorable treatment outcomes. Overall mortality was 11% (n = 9) at 18 months after initiation of treatment. Malnutrition (aOR 27.4, 95%CI 2.7-278.7) and severe radiographic findings (aOR 4.68, 95%CI 1.01-21.9) were associated with unfavorable outcome. New pediatric outcome definitions increased the proportion classified as cured. CONCLUSION: It is possible to successfully treat pediatric MDR-TB-HIV even in resource-poor settings. Malnutrition is a marker for severe TB-HIV disease, and is a potential target for future interventions in these patients.
