OBJECTIVES. The goals were to describe the management of multidrug-resistant tuberculosis among children, to examine the tolerability of second-line antituberculosis agents among children, and to report the outcomes of children treated for multidrug-resistant tuberculosis in poor urban communities in Lima, Peru, a city with high tuberculosis prevalence. METHODS. A retrospective analysis of data for 38 children <15 years of age with multidrug-resistant tuberculosis, either documented with drug sensitivity testing of the child's tuberculosis isolate or suspected on the basis of the presence of clinical symptoms for a child with a household contact with documented multidrug-resistant tuberculosis, was performed. All 38 children initiated a supervised individualized treatment regimen for multidrug-resistant tuberculosis between July 1999 and July 2003. Each child received 18 to 24 months of therapy with ≥5 first- or second-line drugs to which their Mycobacterium tuberculosis strain was presumed to be sensitive. RESULTS. Forty-five percent of the children had malnutrition or anemia at the time of diagnosis, 29% had severe radiographic findings (defined as bilateral or cavitary disease), and 13% had extrapulmonary disease. Forty-five percent of the children were hospitalized initially because of the severity of illness. Adverse events were observed for 42 % of the children, but no events required suspension of therapy for >5 days. Ninety-five percent of the children (36 of 38 children) achieved cures or probable cures, 1 child (2.5%) died, and 1 child (2.5%) defaulted from therapy. CONCLUSIONS. Multidrug-resistant tuberculosis disease among children can be treated successfully in resource-poor settings. Treatment is well tolerated by children, and severe adverse events with second-line agents are rare. [ABSTRACT FROM AUTHOR]

Objective: We examined factors associated with in-hospital death among children with tuberculosis (TB). We hypothesized that a negative response to tuberculin skin testing (TST) would predict decreased survival., Methods: This retrospective cohort comprised 2392 children ages 0 to 14 years hospitalized with TB at a Peruvian referral hospital over the 25-year study period. Detailed chart abstraction captured clinical history including TB contacts, physical examination findings, diagnostic data, treatment regimen, and hospitalization outcome. We used Cox proportional hazards regression analyses to determine risk factors for mortality., Results: Of 2392 children, 2 (0.1%) were known to be HIV-positive, 5 (0.2%) had documented multidrug-resistant TB, and 266 (11%) died. The median time from hospitalization to death was 16 days (interquartile range: 4-44 days). Reaction of <5 mm induration on TST predicted death in a multivariable analysis (hazard ratio [HR]: 3.01; 95% confidence interval [CI]: 2.15-4.21; P < .0001). Younger age, period of admission, alteration of mental status (HR: 3.25; 95% CI: 2.48-4.27; P < .0001), respiratory distress (HR: 1.40; 95% CI: 1.07-1.83; P = .01), peripheral edema (HR: 1.97; 95% CI: 1.42-2.73; P < .0001), and hemoptysis (HR: 0.57; 95% CI: 0.32-1.00; P = .05) were associated with mortality. Treatment regimens that contained rifampicin (HR: 0.47; 95% CI: 0.33-0.68; P < .0001) were associated with improved survival., Conclusions: Negative reaction to TST is highly predictive of death among children with active TB. In children with clinical and radiographic findings suggestive of TB, a negative TST should not preclude or delay anti-TB therapy.
