Two Waves of Specific B Cell Memory Immunoreconstruction Observed in Anti-HHV1-3 IgG Kinetics after Hematopoietic Stem Cell Transplantation.

As is typical for infancy, the kinetics of the IgG level is unique after HSCT (the decline phase is first). Host microbiome factors (e.g., HHV1-3-serostatus) should be taken into account to predict risk of non-relapse mortality and survival after HSCT. The levels of specific antibodies help in predicting prognoses and improve disease management. A lack of differentiation and the confusing bias of the assessor (i.e., observer selection bias) are the main obstacles in statistical HHV1-3 research. Such time-lapse case studies may be the first to build evidence of a pathway and an association between immune parameters and HHV disease.
