B Cell Reconstitution and Influencing Factors After Hematopoietic Stem Cell Transplantation in Children
Nicolaas G. van der Maas, Dagmar Berghuis, Mirjam van der Burg and Arjan C. Lankester* Willem-Alexander Children's Hospital, Department of Pediatrics and Laboratory for Pediatric Immunology, Leiden University Medical Center, Leiden, Netherlands B cell reconstitution after hematopoietic stem cell transplantation (HSCT) is variable and influenced by different patient, donor, and treatment related factors. In this review we describe B cell reconstitution after pediatric allogeneic HST, including the kinetics of reconstitution of the different B cell subsets and the development of the B cell repertoire, and d...

Safety of live vaccinations on immunosuppressive therapy in patients with immune-mediated inflammatory diseases, solid organ transplantation or after bone-marrow transplantation - A systematic review of randomized trials, observational studies and case reports.
CONCLUSIONS: Although live vaccinations were safe and sufficiently immunogenic in most studies, some serious reactions and vaccine-related infections were reported in immunosuppressed IMID and SOT patients. Apart from mild vaccine-related infections MMR and VV vaccines were safe when administered less than two years after BMT. IMPLICATIONS OF KEY FINDINGS: Until further data are available, live vaccinations under most immunosuppressive treatments should only be administered after a careful risk benefit assessment of medications and dosages. FUNDING: None. PMID: 28162821 [PubMed - as supplied by publisher]
