conferenceObject INTERSTITIAL GLUCOSE MONITORING IN PATIENTS WITHOUT KNOWN DIABETES MELLITUS WITH HEMATOLOGIC MALIGNANCIES AND SUBMITTED TO CORTICOSTEROIDS DURING CHEMOTHERAPY (LIBREONCO STUDY)(2019) CUKIER, P.; TOYOSHIMA, M. T. K.; SOUZA, A. B. C. de; AZEVEDO, D. P. de; NUNES, L. C. R.; HOFF, A. A. O.; NERY, M.- Fructosamine and glycated hemoglobin as biomarkers of glycemic control in people with type 2 diabetes mellitus and cancer (GlicoOnco study)(2023) TOYOSHIMA, Marcos Tadashi Kakitani; CUKIER, Priscilla; DAMASCENA, Aline Santos; BATISTA, Rafael Loch; CORREA, Fernanda de Azevedo; KAWAHARA, Eduardo Zanatta; MINANNI, Carlos Andre; HOFF, Ana O.; NERY, MarciaIntroduction: Glycemic control is important to avoid diabetes complications in individuals with cancer. There is no evidence for HbA1c and fructosamine as reliable biomarkers in these conditions. There are particularities in caring for patients with diabetes and cancer that can alter these biomarkers.Objective: The aim of this study was to evaluate HbA1c and fructosamine as glycemic biomarkers in people with type 2 diabetes and cancer, undergoing clinical or surgical oncological treatment. Methods: The authors conducted a single-center, retrospective analysis with people who have cancer and diabetes. Comparison of glycemic biomarkers (HbA1c, fructosamine, and Self-Monitoring of Blood Glucose [SMBG]) was performed including evaluation in individuals undergoing chemotherapy, using glucocorticoids, with anemia, hypoproteinemia or with reduced estimated Glomerular Filtration Rate (eGFR).Results: There was a strong positive correlation between fructosamine and HbA1c (n = 318, r = 0.66, p < 0.001) in people with diabetes and cancer even in those under chemotherapy (n = 101, r = 0.61, p < 0.001) or using glucocorticoids (n = 96, r = 0.67, p<0.001). There was a strong correlation between HbA1c and fructosamine in subjects with anemia (n = 111, r = 0.66, p < 0.001), hypoproteinemia (n = 54, r = 0.67, p < 0.001), or with eGFR & GE; 60 mL/min/1.73 m2 (n = 189, r = 0.70, p < 0.001), and moderate correlation with hypoalbuminemia (n = 21, r = 0.54, p = 0.001) and with reduced eGFR (n = 67, r = 0.57, p < 0.001). The correlations between fructosamine and HbA1c with SMBG were moderate (n = 164, r = 0.49, p < 0.001; n = 111, r = 0.55, p < 0.001, respectively), strong in subjects undergoing chemotherapy, with hypoalbuminemia or hypoproteinemia, and at least moderate, if eGFR < 60 mL/min/1.73 m2 or with anemia. Conclusions: Fructosamine and HbA1c can be used as glycemic biomarkers in people with diabetes and cancer, even in those with anemia, hypoproteinemia, or undergoing chemotherapy.
- Effects of glucocorticoids on interstitial glucose concentrations in individuals with hematologic cancer and without known diagnosis of diabetes: a pilot study(2022) TOYOSHIMA, Marcos Tadashi Kakitani; CUKIER, Priscilla; SOUZA, Alexandre Barbosa Camara de; PEREIRA, Juliana; HOFF, Ana Oliveira; NERY, MarciaObjective: To analyze interstitial glucose behavior during glucocorticoid use in non-diabetic patients receiving chemotherapy for hematologic malignancies. Methods: Prospective pilot study carried out to assess interstitial glucose levels in 15 non-diabetic individuals with hematologic malignancies who received glucocorticoids in combination with chemotherapy. The FreeStyle Libre flash monitoring system (Abbott Diabetes Care) was used for up to 14 days to measure interstitial glucose. Results: Median age and body mass index were 53 (42-61) years and 25 (23-28) kg/m(2) respectively. Interstitial glucose levels >180mg/dL lasting at least one hour were detected in 60% of participants. Interstitial glucose profile parameters (median and peak interstitial glucose levels and percentage of time during which interstitial glucose levels were >180mg/dL) were significantly (p<0.01) higher during glucocorticoid use (115mg/dL, 218mg/dL and 10% respectively) than after glucocorticoid discontinuation (97mg/dL, 137mg/dL and 0% respectively). Mean interstitial glucose levels increased in the afternoon and at night during glucocorticoid use. Conclusion: This pilot study was the first to evaluate interstitial glucose levels in non-diabetic individuals using glucocorticoids in treatment of hematologic cancer. Glucocorticoid use during chemotherapy significantly increases interstitial glucose levels in these patients.
- New digital tool to facilitate subcutaneous insulin therapy orders: an inpatient insulin dose calculator(2015) TOYOSHIMA, Marcos Tadashi Kakitani; SOUZA, Alexandre Barbosa Camara de; ADMONI, Sharon Nina; CUKIER, Priscilla; LOTTENBERG, Simao Augusto; LATRONICO, Ana Claudia; NERY, MarciaBackground: Inpatient hyperglycemia is associated with adverse outcomes in hospitalized patients, with or without known diabetes. The adherence to American College of Endocrinology and American Diabetes Association guidelines recommendations for inpatient glycemic control is still poor, probably because of their complexity and fear of hypoglycemia. Objective: To create software system that can assist health care providers and hospitalists to manage the insulin therapy orders and turn them into a less complicated issue. Methods: A software system was idealized and developed, according to recommendations of major consensus and medical literature. Results: HTML software was developed to be readily accessed from a workstation, tablet or smartphone. Standard initial daily total dose of insulin was 0.4 units/kg and could be modified by distinct factors, such as chronological age, renal and liver function, and high dose corticosteroids use. Insulin therapy consisted of basal, prandial and correction insulin according to nutritional support, glycemic control and outpatient treatment for diabetes. Human insulin or insulin analogues could be options for insulin therapy. Sensitivity factor was based on 1800 Rule for rapid-acting insulin and the 1500 Rule for short-acting insulin. Insulin-naive patients with initial BG level less than 250 mg/dL were considered to have an initial step-wise approach with prandial and correction insulin. The calculator system has allowed insulin dose readjustments periodically, according to daily average blood glucose measurements. Conclusion: We developed software that can be a useful tool for all public hospitals, where generally human insulin is the only available.
