Patients who receive autologous hematopoietic cell transplantation (HCT) for the treatment of hematologic malignancies are at risk of serious adverse outcomes including infections and death. Hyperglycemia following the HCT is associated with increased risk of these adverse outcomes. However, limited information is available on demographic and clinical characteristics that contribute to changes in blood glucose levels following HCT.
The objective of this study was to determine the trajectories of fasting blood glucose (FBG) levels as well as the demographic and clinical characteristics that predicted interindividual differences in these FBG trajectories.
A sample of adult patients with hematologic malignancies who were scheduled to receive autologous HCT (n = 53) was enrolled in the study. Patients with preexisting diabetes were excluded. Demographic and clinical characteristics were abstracted from electronic medical records. Morning fasting laboratory tests (ie, FBG and absolute neutrophil counts) were obtained. Data were analyzed using hierarchical linear modeling from the day of HCT (day 0) through 14 days post-HCT.
Among 8 characteristics evaluated, pre-HCT FBG was associated with variability in both the initial levels and the trajectories of FBG. Body mass index was only associated with initial levels of FBG.
The large amount of interindividual variability in the trajectories of FBG levels following autologous HCT suggests that glucose control in these patients warrants ongoing assessments and preemptive tailoring.
Fasting blood glucose monitoring is warranted. Additional research with larger samples is warranted to identify additional modifiable and nonmodifiable characteristics associated with interindividual variability in FBG levels.
