In this week’s episode, we will review a prospective study suggesting that eculizumab discontinuation based on complement genetics is a reasonable and safe strategy in patients with atypical hemolytic uremic syndrome, examine a study that provides new insights into resistance mechanisms and immune evasion in T-cell acute lymphoblastic leukemia, and finally look at a research article describing a new disorder associated with variants in the TLR8 gene that is characterized by neutropenia, infections, lymphoproliferation, B-cell defects, and bone marrow failure.
