RESUMO

BACKGROUND: Hepatocellular injury has been reported commonly in adults on rifampicin-resistant and multidrug-resistant tuberculosis (RR/MDR-TB) treatment. However, there are limited data in children. METHODS: Two pharmacokinetic studies of children (0-17 years) routinely treated for RR/MDR-TB were conducted in Cape Town, South Africa between October 2011 and February 2020. Hepatocellular injury adverse events (AEs; defined as elevated alanine aminotransferase [ALT]) were documented serially. Data were analyzed to determine the incidence, etiology, risk factors, management and outcome of ALT elevation. RESULTS: A total of 217 children, median age 3.6 years (interquartile range, 1.7-7.1 years) at enrollment were included. The median follow-up time was 14.0 months (interquartile range, 9.8-17.2 months). Fifty-five (25.3%) patients developed an ALT AE. Of these, 43 of 55 (78%) patients had 54 ALT AEs attributed to their RR/MDR-TB treatment. The incidence rate of ALT AEs related to RR-TB treatment was 22.4 per 100 person-years. Positive HIV status and having an elevated ALT at enrollment were associated with time to ALT AE attributed to RR/MDR-TB treatment, with P values 0.0427 and P < 0.0001, respectively. Hepatitis A IgM was positive in 11 of 14 (78.6%) severe (grade ≥3) cases of ALT AEs. In 8 of 14 (57%) severe ALT AEs, hepatotoxic drugs were stopped or temporarily interrupted. None had a fatal or unresolved outcome. CONCLUSIONS: Hepatocellular injury in children on RR/MDR-TB treatment is common, although usually mild; having elevated ALT early in treatment and HIV-positive status are possible risk factors. Hepatitis A was a common etiology of severe ALT AE in children treated for RR/MDR-TB.

RESUMO

BACKGROUND: Early initiation of antiretroviral therapy (ART) in HIV-infected infants reduces mortality and opportunistic infections including tuberculosis (TB). However, young HIV-infected children remain at high risk of TB disease following mycobacterial infection. We document the spectrum of TB disease in HIV-infected children <2 years of age on ART. METHODS: Retrospective cohort study; records of children <2 years of age initiating routine ART at Tygerberg Children's Hospital, Cape Town, January 2003-December 2010 were reviewed. Clinical data at ART initiation (baseline) and TB episodes after ART initiation, to June 2012, were recorded. TB immune reconstitution syndrome (TB-IRIS) and incident TB were defined as TB diagnosed within 3 months, and >3 months after, ART initiation respectively. Baseline characteristics were compared in children with TB-IRIS and those with incident TB. RESULTS: In 494 children, median follow-up time on ART was 10.7 months. Fifty-five TB treatment episodes occurred after ART initiation: 23 (42%) TB-IRIS (incidence 21.9/100 person years (py)) and 32 (58%) incident TB (incidence 3.9/100 py). Children with TB-IRIS and those with incident TB had similar baseline characteristics. Eight of 10 cases of extrapulmonary TB were severe: 4 IRIS (2 meningitis, 1 disseminated, 1 pericarditis) and 4 incident cases (1 each miliary, meningitis, pericarditis and spinal). Fifty-one children (10%) died (mortality rate 5.96/100 py). Starting ART at <1 year of age approached significance as a risk factor for TB-IRIS (adjusted OR (AOR) 8.64, p=0.06); weight-for-age Z score <-2 predicted death (AOR 6.37, p<0.001). CONCLUSIONS: Severe TB manifestations were observed among young HIV-infected children on ART.
