SARS-CoV-2 infection can cause severe pneumonia (COVID-19). There is evidence that patients with comorbidities are at higher risk of a severe disease course. The role of immunosuppression in the disease course is not clear. In the present report, we first describe two cases of persisting SARS-CoV-2 viraemia with fatal outcome in patients after rituximab therapy.

Progress during the past 15 years has enabled us to perform pediatric liver transplantation with near perfect patient survival. Advances in posttransplant care of the recipients, technical refinements, standardization of surgery and monitoring, and adequate choice of the donor organ and transplantation technique enable these results, which mark a turning point at which immediate survival after transplantation will be considered the norm. The long-term treatment of the transplanted patient, with the aim of avoiding late graft loss and achieving optimal quality of life, will become the center of debate.

The technical development of splitting along Cantlie's line is almost complete with the last challenge being the reduction of biliary complications. The key to success is the choice of adequate deceased donors and recipients. Full-right full-left splitting is safely possible and should be considered as a reasonable instrument to alleviate mortality on the adult waiting list and to reduce the need for adult and adolescent living donation.

The learning curve in pediatric liver transplantation has reached a turning point where immediate patient survival is considered the rule. The challenge is to increase graft survival to the same level. The long-term management of the transplant patients, with the aim of avoiding late graft loss and achieving excellent quality of life, will become the center of the debate.

Both PVL and PVE are able to induce hypertrophy of the future liver remnant. In comparison, PVE is the more effective technique to increase the future liver remnant. This is due to a more effective, durable occlusion of the portal branches. Formation of collaterals between occluded and nonoccluded liver parts seems to be the cause of inferior regeneration in the ligation group.

In a single center, morbidity after living liver donation strongly correlates to center experience. Despite the additional risks associated with temporary reduction of liver function, this experience enabled the team to bypass part of the learning curve when starting right lobe donation. Specific training of the surgical team and coaching by an experienced center should be implemented for centers offering this procedure to avoid the learning curve.
