    Acute Myeloid Leukemia (AML) is the most common hematologic malignancy. Malglycemia is a disorder of glucose metabolism and includes hyperglycemia, hypoglycemia and the combination of hyperglycemia and hypoglycemia. Malglycemia has been shown to occur frequently during hospitalization among critical care patients and has been associated with increased risk of sepsis and mortality. Little is known, however, about the prevalence and role of malglycemia on the health outcomes of AML patients hospitalized for initial induction therapy. Malglycemia may be of particular importance to the patient with AML because, researchers have found that malglycemia may promote cellular changes which facilitate the progression of cancer, alter treatment response, and attenuate immune response. The purpose of this study was to determine the prevalence of malglycemia (hyperglycemia, hypoglycemia or the combination) and to examine its role on a comprehensive set of health outcomes (neutropenic days, infection, and septicemia, and sepsis, induction hospital length of stay, complete remission and mortality) in AML patients hospitalized for initial induction therapy. A retrospective cohort study design was used. Records of 103 AML patients, hospitalized for initial induction chemotherapy were reviewed. Results of the study showed that 98% of the AML patients had at least one episode of hyperglycemia, with a prevalence rate of 33% over the entire induction inpatient hospitalization for this population. All patients noted with hyperglycemia also had hypoglycemia and thus, the prevalence rate of hypoglycemia alone could not be determined. Prevalence of the combination of hyperglycemia and hypoglycemia was 1.4 %. Although not statistically significant, a trend was noted for AML patients with hyperglycemia to experience more days with neutropenia, greater numbers of infection, sepsis, septicemia and death (mortality) than patients without hyperglycemia during induction treatment. Patients with the combination of hyperglycemia and hypoglycemia also experienced an increased risk of developing septicemia (p = .025) and sepsis (p =.057). Future studies with larger sample sizes are needed to confirm these findings.
