Core Tip

Core Tip: Both adult and pediatric data recently reported a liver involvement in coronavirus disease 2019 (COVID-19). Although several pathogenic mechanisms have been proposed, inflammatory pathways seem to play a pivotal role in the pathophysiology of liver damage in this viral infection. In particular, a complex and bidirectional relationship has been highlighted between fatty liver and COVID-19. Several data suggested this intriguing interplay by underscoring the need for an early close monitoring of this liver condition with an intrinsic greater cardiometabolic burden.
