Frequency and cost of diabetic ketoacidosis in Germany--study in 12,001 paediatric patients

Subcutaneous regular insulin use for the management of diabetic ketoacidosis in resource limited setting

OBJECTIVES

The standard recommendation of insulin therapy for patients with DKA is the administration of slow continuous intravenous (IV) regular insulin. Currently subcutaneous insulin is being recommended as an alternative treatment of DKA in mild and moderate cases in resource-limited settings. The purpose of this study was to assess the effectiveness and safety of six-hourly subcutaneous regular insulin use for the treatment of DKA among children with type one diabetes mellitus.

METHODS

A retrospective cohort study was conducted among 224 DKA episodes which occurred in 161 children who were treated at St. Paul's Hospital Millennium Medical College in Addis Ababa, Ethiopia, from November 2015 to November 2020.

RESULTS

Majority (68.8%) of the episodes occurred in newly diagnosed cases. The median time for urinary ketones clearance was 24 h. DKA severity was found to be the only significant predictor of time to DKA resolution. Only 13 (5.8%) were treated at the pediatric intensive care unit (PICU), and 27 (12.1%) developed complications during management. No death or neurological complications observed.

CONCLUSIONS

The six-hourly subcutaneous regular insulin use was found to be safe and effective alternative to slow IV insulin infusion for the treatment of DKA in a non PICU setting. As it resulted in minimum morbidity and no mortality, we recommend its use in the treatment of DKA irrespective of its severity. It can also decrease the health care cost and patients' inconvenience.

The relationship between diabetes mellitus and attention deficit hyperactivity disorder: A systematic review and meta-analysis

BACKGROUND

This study aims to investigate the prevalence estimate of diabetes mellitus (DM) among people with attention deficit hyperactivity disorder (ADHD) as well as the prevalence of ADHD among those with DM. In addition, the impact of ADHD on glycemic control in patients with DM was also assessed using a systematic review and meta-analysis of currently available published data.

MATERIALS AND METHODS

The PubMed, Embase, Web of Science, and PsycInfo databases were searched for potential studies. Two reviewers independently selected studies according to the inclusion and exclusion criteria. All pooled analyses were conducted using the random-effects models on Review Manager 5.3.

RESULTS

Seventeen observational studies were included. The pooled results showed an increase in the prevalence of DM among patients with ADHD versus those without ADHD [type 1 DM OR: 1.37 (95% CI: 1.17-1.61); type 2 DM OR: 2.05 (95% CI: 1.37-3.07)]. There was an overall 35% increase in the prevalence of ADHD among patients with type 1 DM [OR: 1.35 (95% CI: 1.08-1.73)]. Children with type 1 DM and ADHD had higher levels of hemoglobin A1c [standardized mean of differences: 0.67 (95% CI: 0.48-0.86)], and prevalence of hypoglycemic and ketoacidosis index compared with those without ADHD.

CONCLUSION

Our study revealed the bidirectional associations between ADHD and DM. Patients with ADHD and type 1 DM comorbidities were more likely to have poorer diabetes control. More studies are needed to confirm this association and elucidate the underlying mechanism.

Declining Frequency of Acute Complications Associated with Tubeless Insulin Pump Use: Data from 2,911 Patients in the German/Austrian Diabetes Patienten Verlaufsdokumentation Registry

Objective: To characterize patients with diabetes treated with a tubeless insulin pump (Omnipod^® Insulin Management System; Insulet Corp., Acton, MA), and to evaluate the frequency of acute complications with long-term use of the system. Methods: This retrospective analysis of the German/Austrian Diabetes Patienten Verlaufsdokumentation (DPV) registry included data from 3657 patients with diabetes (n = 3582 type 1, n = 25 type 2, n = 50 latent autoimmune diabetes in adults/other) treated with a tubeless insulin pump. Hemoglobin A1c (HbA1c) levels and frequency of diabetic ketoacidosis (DKA) and severe hypoglycemia (SH) were compared between 1 year pre- and 1 year (n = 2911) or up to 3 years (n = 1311) post-tubeless insulin pump initiation and compared with a contemporary cohort on multiple daily injections (MDI) with 3-year data (n = 1874). Results: Patients using tubeless insulin pump therapy had a median age of 13.7 years [interquartile range 10.8, 17.3], diabetes duration 3.7 years [1.7, 8.0], and HbA1c 7.5% [6.9, 8.2]. In patients with 3 years of follow-up data (n = 1311), the percentage with ≥1 episode of DKA, SH (Level 3, requiring assistance), and SH (coma) event with prior treatment was 6.3%, 5.5%, and 1.7%, respectively. After 3 years of tubeless insulin pump therapy, the frequency of DKA, SH (Level 3), and SH (coma) decreased to 2.2%, 4.1%, and 0.5%, respectively. Both DKA and SH remained significantly lower compared with MDI after adjustment in multiple regression analysis. High treatment retention rates (>90%) were observed. Conclusion: Real-world registry data document that tubeless insulin pump therapy is associated with good glycemic control and a low frequency of DKA and SH in an age group prone to acute complications.

Monthly Video-Consultation for Children With Type 1 Diabetes Using a Continuous Glucose Monitoring System: Design of ViDiKi, a Multimethod Intervention Study to Evaluate the Benefit of Telemedicine

BACKGROUND

The introduction of continuous glucose monitoring (CGM) implies new challenges for diabetes care. As CGM systems are often directly linked to a web-based software solution, structured telemedicine care using a video-consultation may be a new option for families who care for children with type 1 diabetes mellitus (T1DM).

METHODS

"ViDiKi" (Virtual Diabetes Outpatient Clinic for Children and Youth) is a multicenter controlled trial carried out in Northern Germany. ViDiKi will examine if monthly telemedical consultations, in addition to regular care, will improve glycemic control and psychosocial outcomes. The primary outcome is glycemic control as measured by a change in glycated hemoglobin (HbA1c). A total of 240 participants aged between one year and 16 years using a CGM with multiple daily injections (MDI) or insulin pump therapy were recruited and assigned to a starter group or a six-month waiting control group. The sample size is designed to detect a between-group difference of 0.5% in HbA1c change at six months. Secondary outcomes are variability of blood glucose, health-related quality of life, self-efficacy, and satisfaction with telemedicine. To gain deeper insight into the experience of using telemedicine, qualitative interviews will be conducted. In a health-economic analysis, the costs of telemedicine and a cost-of-care analysis will be calculated.

CONCLUSIONS

The results from the ViDiKi study shall give important information on the feasibility and putative benefits of telemedicine in children with T1DM and their caregivers.

[An investigation of ketoacidosis in children with newly diagnosed type 1 diabetes]

OBJECTIVE

To investigate the incidence of diabetic ketoacidosis (DKA) in children with newly diagnosed type 1 diabetes.

METHODS

A retrospective analysis was performed for the clinical data of 224 children with newly diagnosed type 1 diabetes, and according to the presence or absence of DKA, these children were divided into DKA group and non-DKA group, with 112 children in each group. The DKA group was further divided into ≥5-year group (65 children) and <5-year group (47 children), and according to the blood gas parameters, this group was divided into mild group (26 children), moderate group (29 children), and severe group (57 children). The factors influencing the development of DKA were analyzed, as well as the clinical and laboratory features of DKA children with different ages.

RESULTS

The most common symptoms in these 224 children with type 1 diabetes were polydipsia (86.2%), polyuria (78.6%), and weight loss (57.1%). Compared with the non-DKA group, the DKA group had a significantly higher percentage of children who were aged <5 years, who had low family income, or whose parents had an educational level of senior high school or below. The DKA group had significantly higher levels of random blood glucose and HbA1C and significantly lower levels of pH, HCO3^-, and C-peptide than the non-DKA group (P<0.05). There was no significant difference in the percentage of children with severe DKA between the ≥5-year group and the <5-year group (P>0.05). Compared with the <5-year group, the ≥5-year group sufferred from symptoms for a significantly prolonged period, and had a significantly lower level of random blood glucose and significantly higher levels of HbA1C and C-peptide (P<0.05).

CONCLUSIONS

DKA has a high incidence rate in children with type 1 diabetes, and the development of DKA is associated with age, parents' educational level, and family income.

20 Years of Pediatric Benchmarking in Germany and Austria: Age-Dependent Analysis of Longitudinal Follow-Up in 63,967 Children and Adolescents with Type 1 Diabetes

BACKGROUND

To investigate changes in diabetes treatment over the last two decades in three age-groups of children and adolescents with type 1 diabetes (T1D) from Germany and Austria.

METHODS

63,967 subjects (<18yr) with T1D documented between 1995 and 2014 from the DPV-database were included and stratified according to age (0.5-<6, 6-<12, 12-<18yr). Regression models were applied for insulin regimens (<3 and ≥4 injection time points/day, or continuous subcutaneous insulin infusion (CSII)), use of rapid- and long acting insulin analogues, NPH insulin, and frequency of self-monitoring of blood glucose (SMBG)/day. Models were adjusted for sex, diabetes duration, and migration background. P-value for trend was given.

FINDINGS

The number of subjects with <3 injection time points/day decreased from 1995 to 2014 to <5% in all age-groups (p<0.0001). Proportion of patients with ≥4 injections/day increased until the early 2000s, and then declined until 2014. This trend was not found in 6-<12yr olds (p = 0.3403). CSII increased in all age-groups (p<0.0001) with the highest increase in children <6 years (from 0.4% to 79.2%), and the lowest increase in 12-<18 year olds (from 1.0% to 38.9%). NPH insulin decreased in all age-groups (p<0.0001). Insulin analogues, especially rapid-acting, became more frequent in all age-groups (p<0.0001), accounting for 78.4% in 2014 for all subjects. The highest use was found in the youngest children (in 2014: 85.6%), the lowest use in 6-<12 year olds (in 2014: 72.9%). The number of SMBG/day increased from 2.2 to 6.4 with a similar rise in all age-groups (p<0.0001). Frequency was highest in subjects <6yr.

CONCLUSIONS

In all age-groups, T1D treatment was intensified over the last 20 years. Age-specific differences in trends were particularly observed in the number of patients on CSII, in the number of patients with 4 or more injections/day, and in the frequency of SMBG/day.
