Diabetes in toddlers & preschool children with type 1 DM
Litton et al 2002 (n=9 aged 10-40 months)Factors leading to poor control
- Unpredictable food intake
- Unpredictable activity levels
- Imprecise administration of low doses of insulin
- Frequent viral infections
- Inability to communicate symptoms of low BG, predisposing to frequent hypos
Diabetes in toddlers & preschool children with type 1 DM
Litton et al 2002 (2)- Patient selection criteria
- Recurrent moderate/severe hyperglycaemia
| Pre-pump | Post-pump | |
| HbA1c persistently > 9.0 | 9.5 +/- 0.4 | 7.9 +/- 0.3 |
| Insulin dose | no sig diffs | |
| BG recordings | no sig diffs | |
| Linear growth | no sig diffs | |
| Weight gain | no sig diffs | |
| Severe hypos/ mth | 0.52 +/- 0.1 | 0.09 +/_ 0.02 |
| Parental clinic contact-days | 5.9 +/- 1.5 | 46.3 +/- 4.4 |
Diabetes in toddlers & preschool children with type 1 DM
Litton et al 2002 (4)- A controlled study of the effects of discontinuation of pump therapy could not be conducted because all our families preferred CSII to MDI and refused to consider a return to previous modes of insulin administration
- ...the frequency of parental contacts with health personnel declined by >80 continued with CSII
Pumps & Paediatrics
Aherne et al 2002 (n=169: age range=1.5-18 yrs)
- “CSII [insulin pump therapy] is an effective alternative to injection therapy in a large paediatric diabetes clinic setting. Even very young patients can utilise CSII to safely lower HbA1c levels”.
- “Improved diabetes control was achieved with CSII without increasing daily insulin doses and in association with a decrease in the frequency of severe hypoglycaemic events (p=0.05 vs prepump, all three ages combined)”.
- “There was a significant and consistent reduction in mean HbA1c levels after 12 months of CSII…(p=<0.02 vs prepump) that was maintained at the most recent visit”.
- “The remarkable effectiveness of CSII in our youngest patients indicates that the child’s age should not be a barrier to the initiation of this therapy”
CSII vs MDI in adolescents: n=75
Boland et al 2000
Severe hypos - events/100 pt yrs (n=55)
Bode et al 1996
- Severe hypos 138 (MDI) vs 22 (Yr 1 CSII).. 36 (Yr 4 CSII)
- Total insulin dose reduced from 42.9 (MDI) to 36.4 (Yr1)..37.8 (Yr4)
- DKA rates were 14.6 / MDI vs 7.6 CSII per 100 pt years ie - No significant difference
DKA Rates in Children & Adolescents (n=6)
Steindel et al 1995
- MDI vs CSII
- DKA episodes 31 vs 10
- Mean no. hospitalisation/pt 5.2 vs1.7
- Mean no. hospital days/pt 20.8 vs 5
- Mean Treatment costs/pt - $'000 $29.33 vs $12.76
Less Day-to-day Fluctuations of Insulin Absorption During CSII Compared to Single Injections of Intermediate-acting Insulin
The absorption of 125I-labeled insulin by six diabetics during injection therapy, respectively eight patients with continuous subcutaneous insulin infusion, was determined during several days.*
Correlation Between HbA1c and Frequency of Blood Glucose Self-monitoring Under Insulin Pump Treatment
Results of a questionnaire* on diabetics with an insulin pump treatment in Germany in 1998/1999. 2481 data sets
{(Diabetes duration: 20 ± 11 years; Treatment with an insulin pump: 3 ± 5 years; Frequency of daily blood glucose self-monitoring: 5.4 ± 1.8; HbA1c: 6.9 ± 1.1 %)
