BACKGROUND AND OBJECTIVE:
Advantages of continuous subcutaneous insulin infusion (CSII) over multiple daily injections with glargine (MDI/G) are still uncertain. We compared CSII vs. MDI/G therapy in unselected patients with type 1 diabetes using continuous glucose monitoring (CGSM). The primary end-points were glycaemic control and quality of life (QOL).
METHODS:
A total of 45 patients with long-term diabetes and mean HbA1c values of 8.6±1.8% (70.5±15.4mmol/mol), previously treated with MDI/NPH, were switched to MDI/G for 6 months and then, unfulfilling therapy CSII indication, were randomly assigned to CSII or MDI/G for another six months. We evaluated QOL (EsDqol) and glycaemic control by measuring HbA1c levels, rate of hypoglycaemia, ketoacidosis and CGSM data.
RESULTS:
After the first phase (MDI/NPH to MDI/G) there was a significant improvement in total EsDQOL (99.72±18.38 vs. 92.07±17.65; p<0.028), a 0.5% decrease in HbA1c values (8.4±1.2 vs. 7.9±0.7% [68±9.7 vs. 63±5.5mmol/mol]; p<0.032), an improvement in glycaemic variability (standard deviation 66.9±14 vs. 59.4±16mg/dl; p<0.05), a decrease in insulin requirements (0.87±0.29 vs. 0.80±0.25U/kg; p<0.049), a decrease in number of severe hypoglycaemia episodes (0.44±0.9 vs. 0.05±0.2; p<0.014), and an increase in periods of normoglycaemia measured with CGSM (15.8±10.9% vs. 23±18.4%; p<0.003).
Six months after randomization, significant improvements were seen in the HbA1c (7.9±0.7 vs. 7±0.6% [63±5.5 vs. 53±4.5mmol/mol]; p<0.001) and EsQOL (91.66±22 vs. 84.53±1.63; p<0.045) only in the CSII group. The HbA1c value was significantly lower when compared with the MDI/G group (CSII 7±0.6% [53±4.5mmol/mol] vs. MDI/G 7.6±0.9% [59.6±7.7mmol/mol]; p<0.03).
CONCLUSIONS:
Intensive insulin therapy with CSII vs. MDI/G was associated with better levels of HbA1c in patients with long-term type 1 diabetes.
