Background: Little is known about the distribution of posaconazole in brain tissue and CSF. We therefore analysed trough concentrations of posaconazole in paediatric leukaemia patients in non-inflamed CSF.

Patients And Methods: The study included paediatric patients <18 years of age with acute leukaemia in remission who underwent repeat therapeutic lumbar punctures as part of their anti-leukaemia treatment.

Invasive fungal diseases (IFDs) play an important role in the supportive care of paediatric patients with acute leukaemia and those undergoing allogeneic haematopoietic cell transplantation, and they are associated with significantly decreased overall survival rates in affected individuals. Relative to adults, children and adolescents are distinct in terms of host biology, predisposing conditions, presentation and epidemiology of fungal diseases, and in the pharmacology of antifungal agents. The paediatric development of antifungal agents has moved forward in a coordinated manner, and major advances have been made regarding concepts and recommendations for the prevention and treatment of IFDs.

Background: Parvovirus B19 (B19V) infection following pediatric hematopoietic cell transplantation (HCT) is a rare complication and available data is scarce. Therefore, we present the experience with B19V Infection in allogeneic pediatric HCT recipients at our transplant center together with a systematic review of the literature.

Methods: Pediatric HCT patients with Parvovirus B19 infection treated at the University Children's Hospital Münster between 1999 and 2021 were retrospectively identified and clinical data were analyzed.

Article Synopsis
  • Cytomegalovirus (CMV) infections are common in patients getting haematopoietic cell transplantation (HCT) and can lead to serious health issues. Letermovir is a prophylactic treatment that's effective for adults but not yet approved for kids.
  • A study was done on 17 pediatric HCT patients to see how letermovir worked for preventing or treating CMV infection since they received it outside of clinical trials.
  • Results showed that letermovir helped manage CMV effectively; most patients either had no viral replication or only temporary viral activity, and there were no significant side effects leading to treatment discontinuation.

Common pediatric solid cancers fail to respond to standard immuno-oncology agents relying on preexisting adaptive antitumor immune responses. The adoptive transfer of tumor-antigen specific T cells, such as CAR-gene modified T cells, is an attractive strategy, but its efficacy has been limited. Evidence is accumulating that local barriers in the tumor microenvironment prevent the infiltration of T cells and impede therapeutic immune responses.
