Insights
Continuous subcutaneous insulin infusion (CSII) significantly improved glucose control in children and adolescents with type 1 diabetes mellitus (T1DM) in Qatar. This study demonstrated a notable reduction in HbA1c levels after one year of CSII use.
Area of Science:
- Pediatric Endocrinology
- Metabolic Disorders
- Diabetes Technology
Background:
- Type 1 diabetes mellitus (T1DM) requires intensive management to prevent complications.
- Continuous subcutaneous insulin infusion (CSII) offers a flexible alternative to multiple daily injections.
- Standardized protocols are crucial for optimizing CSII outcomes in pediatric populations.
Purpose of the Study:
- To evaluate the effectiveness of CSII in improving glycemic control in children and adolescents with T1DM.
- To describe CSII usage characteristics in a Qatari cohort.
- To assess the impact of a standardized CSII protocol on HbA1c levels.
Main Methods:
- A cohort of 138 T1DM patients (mean age 9.8 years) initiated CSII using Medtronic insulin pumps.
- CSII characteristics and glycated hemoglobin (HbA1c) were assessed one year post-initiation.
- Data analysis focused on changes in insulin dosage and HbA1c levels.
Main Results:
- A significant increase in daily insulin dose (0.59 to 0.74 U/kg/24h) was observed.
- Glycated hemoglobin (HbA1c) levels significantly decreased from 9.7% to 8.1% (P < 0.05).
- Over 92% of patients utilized the Bolus Wizard feature with specific settings for insulin-to-carbohydrate ratio, insulin sensitivity, and target glucose ranges.
Conclusions:
- CSII, when implemented with a standardized protocol, significantly enhances glucose control in pediatric T1DM patients.
- A mean HbA1c reduction of 1.6% was achieved within one year of CSII initiation.
- Longer-term studies are warranted to confirm these findings and assess sustained benefits.
Aim:
To describe continuous subcutaneous insulin infusion (CSII) characteristics in type 1 diabetes mellitus (T1DM) children and adolescents using a standardized protocol in routine clinical settings in Qatar.
Methods:
A total of 138 T1DM patients (62 males; 76 females; mean age 9.8 ± 3.4 years) with a mean diabetes duration of 2.4 ± 1.9 years initiated CSII (MiniMed® Veo®™ and MiniMed® 640 G insulin pumps; Medtronic, Northridge, CA, USA) in 2016 and 2017. CSII characteristics and glycated hemoglobin (HbA1c) were evaluated 1 year after treatment initiation.
Results:
At 1 year after treatment initiation, the insulin dose had significantly increased (from 0.59 ± 0.23 to 0.74 ± 0.26 U/kg body weight per 24; P < 0.05), and the HbA1c level had significantly decreased (from 9.7 ± 1.3 to 8.1 ± 0.6%; P < 0.05). More than 92% of patients used the Bolus Wizard feature of the insulin pump at the following settings: insulin-to-carbohydrate ratio 19.2 ± 9.3 g; insulin sensitivity factor 131 ± 68 mg/dl; target range 91 ± 9.3-135 ± 14.2 mg/dl; active insulin time 3.8 ± 0.8 h.
Conclusion:
Our results show that CSII may significantly improve glucose control in T1D children and adolescents who use a standardized protocol. A reduction of HbA1c by - 1.6% was achieved at 1 year after CSII initiation. These results need to be confirmed in a study with a longer duration.
