We herein report a 56-year-old man with severe hypocalcemia during ruxolitinib therapy for myelofibrosis transitioning from JAK2 mutation-positive polycythemia vera. Blood transfusions were administered every one to two weeks for ruxolitinib-induced anemia. Blood tests revealed hypocalcemia with low TRACP-5b, 25-hydroxyvitamin D (25 (OH) D), and 1,25-dihydroxyvitamin D (1,25 (OH) D) levels within the lower reference range.

Familial platelet disorder (FPD) is associated with germline mutations, establishing a preleukemic state and increasing the risk of developing leukemia. Currently, there are no intervention strategies to prevent leukemia progression. Single-cell RNA sequencing ( = 10) combined with functional analysis of samples from patients with -FPD ( > 75) revealed that FPD hematopoietic stem and progenitor cells (HSPCs) displayed increased myeloid differentiation and suppressed megakaryopoiesis because of increased activation of prosurvival and inflammatory pathways.

Background: Immune checkpoint inhibitor (ICI)-induced myocarditis is a life-threatening adverse drug reaction. Abatacept (a CTLA-4-immunoglobulin fusion protein) has been proposed as a compassionate-use treatment for ICI myocarditis (in combination with corticosteroids and ruxolitinib) but no clinical trial has yet been performed. The abatacept dose can be adjusted using real-time assessment of its target, the CD86 receptor occupancy on circulating monocytes (CD86RO).

Background: Adoptive therapy with umbilical cord blood (UCB) T-regulatory (Treg) cells can prevent graft vs. host disease (GVHD). We hypothesize that UCB Tregs can treat GVHD and synergize with ruxolitinib, Jak2 inhibitor, to improve outcomes.
