Schooling diabetes: Use of continuous glucose monitoring and remote monitors in the home and school settings.

BACKGROUND: Despite significant advances in type 1 diabetes (T1D) management, achieving targeted glycemic control in pediatric patients remains a struggle. Continuous glucose monitoring (CGM) with remote access holds the promise to address this challenge by allowing caregivers to monitor glucose, even when the child is not directly under their supervision. OBJECTIVE: To explore real-time and remote CGM practices in homes and schools, including caregiver expectations regarding this technology. SUBJECTS: Parents and daytime caregivers. METHODS: Respondents answered an anonymous survey assessing characteristics of CGM use. Cross-sectional data were collected and analyzed using quantitative and qualitative methods. RESULTS: Thirty-three parents and 17 daytime caregivers responded. Threshold alerts (alerts when patients reached certain pre-set high or low limits) were used most frequently, followed by rate of change alerts. Most parents and daytime caregivers responded to low- and high-threshold CGM alerts by confirming with a glucose meter prior to treatment; while about one-third endorsed treating lows without a confirmatory test. Most parents expected their child's daytime caregiver to respond to CGM alerts and daytime caregivers felt the parent's expectations of them were reasonable. All parents and most caregivers reported decreased overall worry/stress. Parents felt positive about CGM use and daytime caregivers felt comfortable with CGM. CONCLUSION: The positive and collaborative management reported by parents and daytime caregivers sets the stage for CGM to play an important role in the management of children with T1D both in the home and in the school settings.

An Effective Diabetic Ketoacidosis Prevention Intervention in Children With Type 1 Diabetes.

The objective of this study was to evaluate the effectiveness of a brief, office-based educational intervention to increase parent or patient recognition of the early warning signs and symptoms of diabetic ketoacidosis (DKA). Forty-two patients aged > 13 years and 34 parents of children aged ≤ 13 years were given a pretest questionnaire about their knowledge of signs and symptoms of DKA and sick day management practices. They received a brief refresher course on sick day management specific to their treatment modality (pump vs. injection) and were given a take-home flow sheet of guidelines for diabetes sick day management. Subjects were retested with the same knowledge questionnaire after 6 to 12 months. Patients or parents scored higher on the posttest than the pretest and called the emergency line for assistance more frequently (p = .032) following the intervention. Emergency department visits were significantly reduced in adolescents (p = .024). A short educational intervention and printed management tool is effective in improving sick day and DKA knowledge and appears to be effective in reducing emergency department visits by increasing utilization of a diabetes emergency line for early outpatient intervention.

Continuous subcutaneous insulin infusion (CSII) in children with type 1 diabetes.

Recent studies have shown that continuous subcutaneous insulin infusion (CSII), or insulin pump therapy, provides a treatment option that can assist in the attainment of current goals of treatment in children and adolescents with type 1 diabetes (T1DM). In pediatric patients, CSII has been demonstrated to reduce both glycosylated hemoglobin levels and frequency of severe hypoglycemia, without sacrifices in safety, quality of life, or excessive weight gain, particularly in conjunction with the use of new insulin analogs and improvements in pump technology. Clinical studies of safety and efficacy of CSII in children are reviewed.

Insulin pump treatment of childhood type 1 diabetes.

Current goals for the treatment of children and adolescents with type 1 diabetes mellitus include achieving near-normal blood sugar levels, minimizing the risk of hypoglycemia, optimizing quality of life, and preventing or delaying long-term microvascular complications. Continuous subcutaneous insulin infusion (CSII) provides a treatment option that can assist in the attainment of all of these goals in all ages of children. Usage of CSII has been demonstrated to reduce glycosylated hemoglobin levels and frequency of severe hypoglycemia, without sacrifices in safety, quality of life, or weight gain, particularly in conjunction with the use of new insulin analogs and improvements in pump technology. Clinical studies of safety and efficacy of CSII in children are reviewed.

Effectiveness of a spanish language clinic for Hispanic youth with type 1 diabetes.

OBJECTIVE: A pilot study was undertaken to determine whether establishment of a Spanish Language Diabetes Clinic (SLDC) for Spanish-speaking families conducted by a team of Spanish-speaking, Hispanic and nonHispanic clinicians provides a means to improve control of type 1 diabetes (T1D). METHODS: The first 21 Hispanic pediatric patients with T1D who enrolled in the SLDC were matched to 21 Hispanic patients treated in the English Language Diabetes Clinic (ELDC) based on age and duration of diabetes. The two groups did not differ significantly with respect to gender, body mass index (BMI), or glycated hemoglobin (HbA1c). Patients in both groups were followed for 12 months. RESULTS: The mean (± standard deviation) baseline glycated hemoglobin (HbA1c) level in the SLDC group (8.4 ± 1.0%) was similar to that in the ELDC group (8.6 ± 1.4%, P = .83). HbA1c levels fell by 0.5 ± 1.0% (P = .01) during the year following enrollment in the SLDC but did not change significantly from baseline during the year of follow-up in the ELDC group (decrease of 0.2 ± 0.9%, P = .1). At the start of the study, only 5 patients (23%) in the SLDC group and 7 patients (33%) in the ELDC group met the ≤7.5% target HbA1c level. After 1 year, 10 of the SLDC patients (48%) and 4 of ELDC patients (19%) had HbA1c levels ≤7.5% (P = .01). CONCLUSIONS: Our preliminary findings support the hypothesis that overcoming language barriers by the establishment of a SLDC can be an effective means of improving metabolic control in youth with T1D in Hispanic families with limited English language skills.

Insulin therapy in children and adolescents.

Insulin therapy is the mainstay of treatment in children and adolescents with type 1 diabetes (T1D) and is a key component in the treatment of type 2 diabetes (T2D) in this population as well. A major aim of current insulin replacement therapy is to simulate the normal pattern of insulin secretion as closely as possible. This aim can best be achieved with basal-bolus therapy using multiple daily injections (MDI) or continuous insulin infusion (CSII) pump therapy. Only a few years ago, options for insulin formulations were limited. There are now more than 10 varieties of biosynthetic human and analogue insulin.

A bridge to insulin pump therapy: twice-daily regimen with NPH and detemir insulins during initial treatment of youth with type 1 diabetes mellitus.

OBJECTIVE: To describe clinical outcomes in youth with new-onset type 1 diabetes mellitus (T1DM) treated with a modified, twice-daily regimen of a mixture of NPH insulin and rapid-acting insulin analogue at breakfast and separate injections of rapid-acting insulin analogue and insulin detemir at dinner. METHODS: Our clinic database was used to describe changes in insulin doses, hemoglobin A1c (A1C) levels, and frequency of severe hypoglycemia during the first year of therapy in young patients with T1DM diagnosed between September 2006 and April 2009. Data are presented as median values (25%, 75%). RESULTS: Overall, 108 patients (62 girls; mean age, 10.0 ± 0.4 years) were eligible for inclusion. Total daily insulin doses at 3, 6, and 12 months were 0.6 (0.4, 0.8), 0.7 (0.4, 0.9), and 0.8 (0.6, 0.9) U/kg, respectively. A1C levels were 9.8% (8.5%, 10.8%) at 2 weeks (baseline). Of the 108 patients, 19 had switched to insulin pump therapy by 3 months and 49 had switched by 12 months after initial diagnosis of T1DM. The 49 pump-treated patients had an A1C of 6.9% (6.6%, 7.3%), whereas the 59 injection-treated patients had an A1C of 7.2% (6.7%, 7.7%) by 12 months. There were only 6 severe hypoglycemic events in 5 patients; none occurred during the first 3 months, none occurred during the night, and all occurred in patients receiving insulin injection treatment. CONCLUSION: A twice-daily insulin regimen that uses insulin detemir for overnight basal replacement and morning NPH insulin to avoid lunch and afternoon snack doses is an effective initial treatment for young patients with new-onset T1DM that can provide a smooth transition to intensive basal/bolus insulin pump therapy.

Practical aspects of real-time continuous glucose monitors: the experience of the Yale Children's Diabetes Program.

Real-time continuous glucose monitoring (RT-CGM) provides new dimension to diabetes management. However, there are many challenges to using RT-CGM successfully. This article aims to present how RT-CGM is integrated into diabetes clinical practice at the Yale Children's Diabetes Program (YCDP). The authors provide factors to consider when choosing one of the commercially available RT-CGM systems and a discussion of key strategies for successful use of RT-CGM for families. Careful training and troubleshooting strategies will ensure the most positive experience possible for a family using RT-CGM.

Effect of age of infusion site and type of rapid-acting analog on pharmacodynamic parameters of insulin boluses in youth with type 1 diabetes receiving insulin pump therapy.

OBJECTIVE: The purpose of this study was to examine the effect of type of insulin analog and age of insertion site on the pharmacodynamic characteristics of a standard insulin bolus in youth with type 1 diabetes receiving insulin pump therapy. RESEARCH DESIGN AND METHODS: Seventeen insulin pump-treated adolescents with type 1 diabetes underwent two euglycemic clamp procedures after a 0.2 unit/kg bolus of either insulin aspart or lispro on day 1 and day 4 of insulin pump site insertion. The glucose infusion rate (GIR) required to maintain euglycemia was the primary pharmacodynamic measure. RESULTS: There were no statistically significant differences in any of the pharmacodynamic parameters between aspart and lispro during day 1 and day 4. However, when the two groups were combined, time to discontinuation of exogenous glucose infusion, and time to half-maximal onset and offset of insulin action were observed significantly earlier during day 4 compared with day 1 (P = 0.03-0.0004), but the overall area under the GIR curve was similar on day 1 and day 4. CONCLUSIONS: With both insulin aspart and lispro, there is an earlier peak and shorter duration of action with increasing duration of infusion site use, but overall insulin action is not affected.

The renaissance of insulin pump treatment in childhood type 1 diabetes.

Current goals for the treatment of children and adolescents with type 1 diabetes mellitus include achieving near-normal blood sugar levels, minimizing the risk of hypoglycemia, optimizing quality of life, and preventing or delaying long-term microvascular and macrovascular complications. Continuous subcutaneous insulin infusion (CSII), or insulin pump therapy, provides a treatment option that can assist in the attainment of all of these goals in all ages of children. In pediatric patients, CSII has been demonstrated to reduce both glycosylated hemoglobin levels and frequency of severe hypoglycemia, without sacrifices in safety, quality of life, or weight gain, particularly in conjunction with the use of new insulin analogs and improvements in pump technology. Clinical studies of safety and efficacy of CSII in children are reviewed, as well as criteria for patient selection and practical considerations using pump therapy in youth with T1DM.

Emerging evidence for the use of insulin pump therapy in infants, toddlers, and preschool-aged children with type 1 diabetes.

Insulin pump therapy has, within the last 10 years, emerged as an increasingly popular modality of treatment to achieve intensive glycemic targets in type 1 diabetes (T1D). The evidence for the benefits of pump therapy has been demonstrated in adults and adolescents; however, until recently there has been a paucity of studies examining the efficacy and safety in pump therapy in very young children. The purpose of this article is to discuss the rationale for insulin pump therapy in infants and toddlers, review the available studies of pump therapy in this population, and show that the data support the use of insulin pumps in our very youngest of patients.
