| Summary: | Magnesium (Mg) is an essential element that is required as a cofactor for many cellular reactions, including immunologic pathways. The aim of this study was to investigate the potential impact of serum Mg levels on allogeneic hematopoietic stem cell transplantation (alloHSCT) outcomes.
Medical records of 340 alloHSCT recipients (median age: 45 [18-71] years; M/F: 210/130) were reviewed for this retrospective study. Serum Mg levels on days -28, -7, 0, +7, +14, +21, +30, +60, and +90 were included in the analysis.
Serum Mg+14 levels predicted nonrelapse mortality (NRM) (P = .025) and had a significant impact on the development of mucositis (P = .027), fungal infection (P = .006), engraftment syndrome (P < .001), sinusoidal obstruction syndrome (SOS) (P = .001), cytomegalovirus (CMV) reactivation (P = .039), and acute graft vs host disease (GvHD) (P < .001). Based on the optimal threshold of serum Mg+14 level (1.33 mg/dL; area under the curve: 0.581 [0.515-0.648]; P = .018), the study group was divided into 2 subgroups as low- and high-Mg+14. The incidence of acute GvHD (P = .002), SOS (P = .013), engraftment syndrome (P = .013), CMV reactivation (P = .001), and Epstein Barr virus reactivation (P = .005) was significantly lower in low-Mg+14 group. The probability of overall survival (OS) was significantly better (P = .002), whereas NRM was lower in the low-Mg+14 group (P = .001).
Hypomagnesemia seems to provide a considerable advantage for the post-transplant outcome, which may confirm its potential role in the immunologic microenvironment and adaptive immunity. |
