Antibiotic-Associated Drug-Induced Liver Injury in Critically Ill Children: A Prospective Observational Study
Abstract
Scientific relevance. Drug-induced liver injury (DILI) is associated, among other things, with the use of antibiotics. Children with DILI are at risk of acute liver failure and even death. However, the literature on the subject provides little information on the possibility of distinguishing the types of hepatic lesions to diagnose potentially life-threatening DILI in time.Aim. The study aimed to describe the phenotype of new-onset DILI associated with antibiotics in critically ill children with nosocomial infection.Materials and methods. The authors conducted a prospective observational study in the resuscitation and intensive care units of the Morozov Children’s City Clinical Hospital from 1 February 2020 to 1 September 2021. The study assessed the incidence of antibiotic-associated DILI using the Global Trigger Tool. The study enrolled 100 critically ill children with nosocomial infection aged 0 to 17 years (44 boys and 56 girls).Results. Signs of hepatotoxicity were detected in 19 patients, including 8 with abnormal liver function tests but normal liver function and 11 with abnormal liver function tests and clinically apparent liver disease. Thus, the incidence of new-onset hepatotoxicity associated with antibiotics amounted to 12.9 cases per 100,000 paediatric patients, and the incidence of DILI was 7.5 cases per 100,000 children. Based on the analysis of medical records, biochemical findings, and relationships between the time of dosing and the manifestation of signs of liver disorder in 11 children, the authors characterised the phenotype of idiosyncratic cholestatic hepatitis. Critically ill children treated with antibiotics showed alanine transaminase activity up to 10 times the upper limit of normal (ULN), bilirubin levels up to 4.45 times the ULN, and gamma-glutamyl transferase activity up to 5 times the ULN. The odds of developing new-onset DILI were the highest with tigecycline (OR: 4.07; 95% CI: 1.32–12.50) and meropenem (OR: 1.84; 95% CI: 1.01–3.36). In 6 patients, clinical signs of idiosyncratic cholestatic hepatitis resolved within a few weeks after antibiotic discontinuation. The other 5 patients with clinical signs of idiosyncratic cholestatic hepatitis died.Conclusions. The authors described the phenotype of idiosyncratic cholestatic liver injury associated with antibiotics in critically ill children. The role of pharmacogenetic markers in the development of DILI associated with antibiotics in critically ill children needs to be assessed further to implement a risk-based approach and mitigate the risks.
