Hyperglycemia requiring insulin during acute lymphoblastic leukemia induction chemotherapy is associated with increased adverse outcomes and healthcare costs

Glycated albumin may have a complementary role to glycated hemoglobin in glucose monitoring in childhood acute leukemia

PURPOSE

Glycated hemoglobin (HbA1c) as a glycemic index may have limited value in pediatric patients with acute leukemia as they often present with anemia and/or pancytopenia. To address this issue, we evaluated the usefulness of glycated albumin (GA) as a glycemic monitoring index in pediatric patients with acute leukemia.

METHODS

Medical records of 25 patients with type 2 diabetes mellitus (T2DM), 63 patients with acute leukemia, and 115 healthy children from Seoul St. Mary's Hospital, The Catholic University of Korea, were retrospectively investigated for serum GA, HbA1c, and fasting blood glucose (FBG) levels, along with demographic data.

RESULTS

GA, HbA1c, and FBG levels did not differ between the control and acute leukemia groups. In the T2DM group, positive correlations were observed among GA, HbA1c, and FBG (P<0.01). Although GA level was not associated with the HbA1c level in the control group, GA and HbA1c levels showed a positive correlation in the acute leukemia group (P=0.045). Regression analysis revealed GA and HbA1c levels to be positively correlated in the acute leukemia and T2DM groups even after adjusting for age, sex, and body mass index z-score (P=0.007, P<0.01).

CONCLUSION

GA may be a useful complementary parameter to HbA1c for glycemic monitoring in pediatric patients with acute leukemia, similar to its use in patients with T2DM.

The real-life management of glucose homeostasis abnormalities in pediatric onco-hematological diseases: data from a national survey

Glycemic abnormalities are a frequent finding in pediatric oncological patients, both during treatment and after its discontinuation. Moreover, impaired glucose tolerance (IGT), impaired fasting glycemia (IFG) and diabetes mellitus (DM) are not rarely diagnosed in non-oncological hematological diseases. To explore the current pediatric Italian approach to the diagnosis and the management of the glycemic alterations in this clinical setting and, thus, to identify and enforce current clinical needs, we submitted an online 23-items survey to all the Italian Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP) centers, and surveys were descriptively analyzed. Thirty-nine AIEOP centers were involved in the study. In 2021, among 75278 children and adolescents affected by an oncological or a hematological disease, 1.2 and 0.65% developed DM, while IGT or IFG were widespread in 2.3 and 2.8%, respectively. The main causes of DM were the use of corticosteroids in patients with cancer and the iron overload in patients with thalassemia. Venous fasting plasma glycemia was the most used tool to detect glycemic abnormalities. The performance of oral glucose tolerance test (OGTT) was extremely limited, except when IFG occurred. Despite the diagnosis of DM, ∼45% of patients with cancer and 30% of patients with one hematological disease did not receive an appropriate treatment. In the other cases, insulin was the drug of first choice. Emerging technologies for diabetes care (glucose sensors and insulin pumps) are not largely used yet. The results of our study support the standardization of the care of the glycemic abnormalities during or after onco-hematologic diseases in the pediatric age. Despite the scarce data in pediatric literature, proper guidelines are needed.

Glucose management in critically ill adults: A qualitative study from the experiences of health care providers

Aims and objective

To explain the components and elements of glucose management in critically ill adult patients from the healthcare providers' experiences.

Background

Critically ill adults are highly susceptible to stress-induced hyperglycaemia due to glucose metabolic disorders. Healthcare workers play a key role in the glycaemic management of critically ill patients. However, there is a lack of qualitative studies on the content and elements of glycaemic management and healthcare workers' perceptions about glycaemic management in China.

Design

Qualitative study that followed the Consolidated Criteria for Reporting Qualitative Research (COREQ) guidelines.

Methods

Individual semi-structured interviews were conducted from January to April 2022. Fifteen physicians and nurses were recruited from ten hospitals in mainland China. Data were analysed using inductive thematic analysis.

Results

Glucose management in critically ill adult patients from their experiences included two parts: the inner ring (practice behaviours) and the external space (methods and drivers). The practice behaviours of glucose management include five elements, while the methods and drivers of glucose management focus on three elements. The content covered under each element was identified.

Conclusion

This study developed a glycaemic management model for critically ill adult patients, clarified its elements based on the perceptions of healthcare providers and elaborated on the methods and drivers covered under each element to provide a reference for physicians and nurses to develop a comprehensive glycaemic management guideline for critically ill adult patients.

Relevance to clinical practice

Our study proposed a glucose management practice model for critically ill adult patients, and the elements and components included in this model can provide a reference for physicians and nurses when performing glucose management in critically ill patients.

The evolution of nutritional care in children and young people with acute lymphoblastic leukaemia: a narrative review

BACKGROUND

Acute lymphoblastic leukaemia (ALL) is the most common paediatric malignancy in the world. Advances in treatment protocols have resulted in survival rates of >80% in most high-income countries (HIC); however, children and young people (CYP) with ALL continue to face significant nutrition-related challenges during treatment.

METHODS

This narrative review outlines the changing landscape of treatment and survivorship for CYP with ALL and the advances in nutrition knowledge that call for changes to clinical nutrition practice.

RESULTS

The incidence of ALL has remained stable in HIC; however, there have been significant advances in survival over the past 30 years. Overweight and obesity are increasingly prevalent in CYP with ALL at diagnosis, during treatment and in survivorship. Coupled with poor diet quality, high-energy and saturated fat intakes, altered eating behaviours and inactivity, this necessitates the need for a shift in nutrition intervention. Undernutrition remains a concern for CYP with high-risk treatment protocols where oral or enteral nutrition support remains a cornerstone of maintaining nutrition status.

CONCLUSIONS

With improved treatment protocols and high survival rates, a shift to focusing on diet quality, prevention of excessive weight gain and obesity during treatment and survivorship is necessary.

Glucose increases proliferation and chemoresistance in chronic myeloid leukemia via decreasing antioxidant Properties of ω-3 polyunsaturated fatty acids in the presence of Iron

BACKGROUND

There is a strong association between hyperglycemia, oxidative stress, inflammation and the onset and progression of diabetes which causes a higher risk of cancer. This study investigated, the effect of concomitant use of omega-3 polyunsaturated fatty acids (ω-3 PUFAs) with iron supplements in hyper-glucose conditions on the K-562 cell line.

METHODS

The effects of iron, ω-3 PUFAs, and a combination of both on K-562 cells were investigated under normal and high glucose conditions. The impact of these treatments was evaluated using multiple methodologies, including the MTT assay for cell viability, quantification of oxidative stress markers [total antioxidant capacity (TAC) and malondialdehyde (MDA)], and analysis of the cell cycle. Furthermore, the expression levels of TNFα and p53 mRNA were measured using Real-time PCR.

RESULTS

The co-treatment of ω-3 PUFAs and iron in the presence of high glucose had notable effects, as evidenced by an increase in cell survival, resistance to imatinib chemotherapy, TNFαmRNA expression levels, MDA levels, and percentage of cells in the G2/S phase. Additionally, there was a decrease in the mRNA expression of p53 and TAC levels compared to treatment in the normal-glucose condition.

CONCLUSION

Hyperglycemic conditions in conjunction with the combined treatment of theω-3 PUFAs and iron, led to reduced anticancer capacity, chemosensitivity, anti-inflammatory and antioxidant properties of the K-562 cells. These effects were found to be mediated by oxidative stress.

Proactive Glucose Screening Tool Effective for Time-sensitive Identification of Hyperglycemia in Childhood Cancer Patients

Approximately 4% to 35% of pediatric patients undergoing treatment for acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LLy) develop drug-induced hyperglycemia. Though hyperglycemia is associated with poor outcomes, no guidelines for identifying drug-induced hyperglycemia currently exist, and the time course for developing hyperglycemia remains relatively uncharacterized after induction therapy. The present study evaluated a hyperglycemia screening protocol that was implemented to identify hyperglycemia more promptly, examined predictors of hyperglycemia during ALL and LLy therapy, and described the timeline for developing hyperglycemia. A retrospective review of 154 patients diagnosed with ALL or LLy at Cook Children's Medical Center between March 2018 and April 2022 was performed. Predictors of hyperglycemia were examined with Cox regression. The hyperglycemia screening protocol was ordered for 88 (57%) patients. Fifty-four (35%) patients developed hyperglycemia. In multivariate analyses, age 10 years or older (hazard ratio = 2.50, P = 0.007) and weight loss (vs gain) during induction (hazard ratio = 3.39, P < 0.05) were associated with hyperglycemia. The present study identified a population of patients at risk of developing hyperglycemia and identifies strategies for hyperglycemia screening. In addition, the present study showed that some patients developed hyperglycemia after induction therapy, which highlights the importance of continued blood glucose monitoring in at-risk patients. Implications and suggestions for further research are discussed.

Improvement of Diet after an Early Nutritional Intervention in Pediatric Oncology

Pediatric cancer survivors may experience cardiometabolic sequelae over the course of their lives as a result of the treatments they have received. While nutrition consists of an actionable target for cardiometabolic health, few nutritional interventions have been documented in this population. This study assessed the changes in diet during a one-year nutritional intervention for children and adolescents undergoing cancer treatments and the participants’ anthropometric and cardiometabolic profiles. A total of 36 children and adolescents (mean age: 7.9 years, 52.8% male) newly diagnosed with cancer (50% leukemia) and their parents underwent a one-year individualized nutrition intervention. The mean number of follow-up visits with the dietitian during the intervention was 4.72 ± 1.06. Between the initial and one-year assessments, there was an improvement in diet quality reflected by the Diet Quality Index (5.22 ± 9.95, p = 0.003). Similarly, the proportion of participants with moderate and good adherence (vs. low adherence) to the Healthy Diet Index score almost tripled after one year of intervention (14% vs. 39%, p = 0.012). In parallel, there was an increase in the mean z-scores for weight (0.29 ± 0.70, p = 0.019) and BMI (0.50 ± 0.88, p = 0.002), and in the mean levels of HDL-C (0.27 ± 0.37 mmol/L, p = 0.002) and 25-hydroxy vitamin D (14.5 ± 28.1 mmol/L, p = 0.03). Overall, this study supports that a one-year nutritional intervention deployed early after a pediatric cancer diagnosis is associated with an improvement in the diets of children and adolescents.

Role of Nutrition in Pediatric Patients with Cancer

Children with cancer are at high risk for developing short-term and long-term nutritional problems related to their underlying disease and side effects of multimodal treatments. Nutritional status (NS) can influence several clinical outcomes, such as overall survival (OS) and event-free survival (EFS), treatment tolerance, risk of developing infections and quality of life (QoL). However, the importance of nutrition in children with cancer is still underestimated. This review focuses on alterations of NS that occurs in children during cancer treatment. In particular, we reviewed the pathogenesis of undernutrition in oncological children, as well as how NS affects treatment tolerance and response, the immune system and the risk of infections of children with cancer. Thanks to recent advances in all types of supportive therapy and to the progress of knowledge on this topic, it has been realized that NS is a modifiable prognostic factor that can be intervened upon to improve the outcome of these patients. Currently, there is a lack of a systematic approach and standard recommendations for nutritional care in the pediatric cancer population. Literature analysis showed that it is essential to define the NS and treat any alterations in a timely manner ensuring proper growth and development. Nutritional follow-up should become an integral part of the care pathway. Regular nutritional monitoring should be performed at diagnosis, during treatment and during follow-up. A close collaboration and sharing of expertise between pediatric oncologists and nutrition specialists, combined with careful and participatory sharing of the feeding experience with the family and the child (after age 6 years), is strongly required.

The Effect of Chemotherapy Induction Therapy on the Pancreas in Patients with Acute Lymphoblastic Leukemia

Background

The effect of chemotherapy induction on the pancreatic in patients with acute lymphoblastic leukemia is not described in Ethiopia. The study determined the chemotherapy drug-induced pancreatitis in patients with acute lymphoblastic leukemia.

Method

A preexperimental study (pretest and posttests) was conducted in forty patients with acute lymphoblastic leukemia. For some skewed data, a log transformation was computed. The back transformation was then calculated. Descriptive statistics and a mixed-model ANOVA were used to analyze the data. A post hoc Bonferroni test was used. A p value < 0.05 was declared statistically significant.

Results

In this study, no clinically significant acute pancreatitis occurred. Elevated amylase and lipase levels, indicating grade 2 acute pancreatitis, were observed in 25% and 17.5% of patients, respectively. Amylase enzyme levels in children differed significantly from preinduction to the second week of induction (p = 0.001) and fourth week of induction (p = 0.001), as well as between the second and fourth weeks of induction (p = 0.033), but adults' amylase enzyme levels did not differ significantly (p = 0.2). Lipase levels in adults are nearly identical in all three measures, implying that there is no statistically significant difference (p = 0.775). However, the level of lipase enzyme in children was significantly higher from baseline to two and four weeks of induction (p = 0.007) but not between two and four weeks of induction (p = 0.129).

Conclusion

Clinically significant acute pancreatitis did not occur, but patients experienced mild (grade 2) acute pancreatitis. Amylase and lipase enzymes responded significantly to chemotherapy induction in children. Chemotherapy drugs should be given without altering pancreatic enzymes, specifically in children.

Drug Induced Diabetes Mellitus in Pediatric Acute Lymphoblastic Leukemia: Approach to Diagnosis and Management

Corticosteroids and l -asparaginase used in the treatment of pediatric acute lymphoblastic leukemia (ALL) can cause drug-induced diabetes mellitus (DIDM). DIDM can lead to dyselectrolytemia, a higher risk of infections including cellulitis, bacteremia, fungemia, and a higher incidence of febrile neutropenia and may have an impact on the outcome of ALL. Literature on the management of DIDM among children with ALL is sparse and the diagnostic criteria for pediatric diabetes should be carefully applied considering the acute and transient nature of DIDM during ALL therapy. Insulin remains the standard of care for DIDM management and the choice of Insulin regimen (stand-alone Neutral Protamine Hagedorn or basal bolus) should be based on the type and dose of steroids used for ALL and the pattern of hyperglycemia. A modest glycemic control (postmeal 140 to 180 mg/dL, premeal <140 mg/dL) to prevent complications of hyperglycemia, as well as hypoglycemia, would be the general approach. This review is intended to suggest evidence-based practical guidance in the diagnosis and management of DIDM during pediatric ALL therapy.

Hyperglycemia during induction therapy for acute lymphoblastic leukemia is temporally linked to pegaspargase administration

BACKGROUND

Chemotherapy regimens containing glucocorticoids and pegaspargase are associated with hyperglycemia; however, the pattern and underlying risk factors are not well characterized. We determined the pattern of hyperglycemia and associated factors in children with acute lymphoblastic leukemia (ALL) receiving glucocorticoids and pegaspargase during induction.

METHODS

Retrospective analysis of patients treated between 2010 and 2020 at a single institution. Pretreatment data, glucose values, and insulin regimens were abstracted from the record. Hyperglycemia was defined as two or more random glucose measurements ≥200 mg/dl. Analyses of demographic and clinical factors were conducted with logistic regression.

RESULTS

Two hundred thirteen patients, median age 6 years (range 1.0-18.9 years), 47% female, were included. The prevalence of hyperglycemia was 23% (n = 48). Mean glucose levels peaked 3 days following administration of pegaspargase. In multivariable analysis, age ≥10 years (odds ratio [OR] 6.2, 95% confidence interval [CI]: 2.9-13.4), female sex (OR 2.7, 95% CI: 1.2-6.2), and family history of diabetes (OR 3.2, 95% CI: 1.4-7.3) were predictive of hyperglycemia. Age ≥10 years (OR 19.4, 95% CI: 5.5-68.4), family history of diabetes (OR 8.2, 95% CI: 2.7-25.3), and higher body mass index (BMI) (OR 1.8, 95% CI: 1.1-2.9) were associated with insulin treatment.

CONCLUSIONS

Onset of hyperglycemia in children receiving induction chemotherapy for ALL is temporally linked to administration of pegaspargase. Older age, female sex, and family history of diabetes are predictive of hyperglycemia during induction; older age, family history of diabetes, and higher BMI are associated with insulin treatment. Frequent glucose monitoring is indicated during induction therapy for ALL.

The Role of Oxidative Stress and Inflammation in Cardiometabolic Health of Children During Cancer Treatment and Potential Impact of Key Nutrients

Significance: The 5-year survival rate of childhood cancers is now reaching 84%. However, treatments cause numerous acute and long-term side effects. These include cardiometabolic complications, namely hypertension, dyslipidemia, hyperglycemia, insulin resistance, and increased fat mass. Recent Advances: Many antineoplastic treatments can induce oxidative stress (OxS) and trigger an inflammatory response, which may cause acute and chronic side effects. Critical Issues: Clinical studies have reported a state of heightened OxS and inflammation during cancer treatment in children as the result of treatment cytotoxic action on both cancerous and noncancerous cells. Higher levels of OxS and inflammation are associated with treatment side effects and with the development of cardiometabolic complications. Key nutrients (omega-3 polyunsaturated fatty acids, dietary antioxidants, probiotics, and prebiotics) have the potential to modulate inflammatory and oxidative responses and, therefore, could be considered in the search for adverse complication prevention means as long as antineoplastic treatment efficiency is maintained. Future Directions: There is a need to better understand the relationship between cardiometabolic complications, OxS, inflammation and diet during pediatric cancer treatment, which represents the ultimate goal of this review.
