Introduction: The continuous subcutaneous insulin infusion (CSII) is an alternative to multiple daily injection therapy in type 1 diabetes and its use is increasingly common due to the beneficial effects on the glycemic control of the patient.
Aims: To find differences on outcomes of CSII therapy between genders. Patients and methods: Patients on CSII therapy in our department were included in the study and we recorded outcomes regarding the following set points: immediately before beginning of CSII therapy, 12 months after inclusion and in the last appointment. For statistical analysis, we used the Students t-test and Pearson correlation, and considered significant a value of P≤0.05.
Results: We studied 64 patients (24 men; 39 women) with a mean HbA1c before initiation of 8.2%±1.4; mean age at the time of placement of 33.6±11.2 years; and mean time of follow up after placement of 2.1±1.9 years. Men had significantly lower levels of HbA1c than women (7.8±0.8% vs 8.4±1.7%, P<0.05). The reduction of HbA1c on the last consultation was not sustained in the group of men, whereas in women there was a persistent tendency to reduction of HbA1c (ΔHbA1c 0.1±1.2% vs ΔHbA1c −1.3±1.6%, P=0.01). There was no significant correlation between duration of diabetes, age, gender and weight change. When adjusted to gender, there was a negative correlation between previous HbA1c and its reduction by the end of follow-up (R=−0.555, P=0.021) and a positive correlation between weight gain and HbA1c reduction at 12 months (R=0.505, P=0.04). There was a significant correlation between duration of diabetes and reduction of HbA1c at 12 months (R=0.600, P=0.01).
Conclusions: In our study we found better results of CSII therapy in women than men, probably reflecting the fact that patients with higher baseline HbA1c benefit most of this diabetes therapeutic modality.
