Abstract
BACKGROUND AND AIMS
We evaluated the effectiveness and safety of pan-genotypic regimens, glecaprevir/pibrentasvir (GLE/PIB), sofosbuvir/velpatasvir (SOF/VEL), and sofosbuvir/daclatasvir (SOF/DCV) and other direct-acting antivirals (DAA) regimens for the treatment of hepatitis C virus (HCV)-infected adolescents (12-18 years), older children (6-11 years), and young children (3-5 years). The purpose of this systematic review and meta-analysis was to inform the World Health Organization (WHO) guidelines.
METHODS
We included clinical trials and observational studies published up to August 11, 2021, that evaluated DAA regimens in HCV-infected adolescents, older children, and young children. We searched MEDLINE, EMBASE, and CENTRAL databases and key conference abstracts. Sustained virological response 12 weeks after the end of treatment (SVR12), adverse events (AEs), and treatment discontinuation were the outcomes evaluated. Risk of bias was assessed using a modified version of the ROBINS-I tool. Data were pooled using random-effects models, and certainty of the evidence was assessed using the GRADE approach.
RESULTS
A total of 49 studies including 1882 adolescents, 436 older children, and 166 young children were considered. The SVR12 was 100% (95% Confidence Interval: 96-100), 96% (90-100), and 96% (83-100) for GLE/PIB in adolescents, older, and young children, respectively; 95% (90-99), 93% (86-98), and 83% (70-93), for SOF/VEL, respectively; and 100% (97-100) and 100% (94-100) for SOF/DCV in adolescent and older children, respectively. There was a clear trend towards a higher rate of any reported AE from adolescents (50%), older children (53%), to young children (72%). Serious AEs and treatment discontinuations were uncommon in adolescents and older children (<1%) but slightly higher in young children (3%).
CONCLUSIONS
All three pan-genotypic DAA regimens were highly effective and well-tolerated and are now recommended by the WHO for use in adults, adolescents, and children down to 3 years, which will simplify procurement and supply chain management. The evidence was based largely on single-arm non-randomized controlled studies. Moreover, there were also missing data regarding key variables such as route of HCV acquisition, presence or absence of cirrhosis, or HIV co-infection that precluded evaluation of the impact of these factors on outcomes.
