Comparative analysis of different drug delivery methods of injectable hydrogel nanomaterials of insulin biomaterials via multiple daily injections and continuous subcutaneous insulin infusion in the treatment of type 1 diabetes mellitus in children

Abstract

The aim of this study was to investigate the difference between multiple daily injections (MDI) and continuous subcutaneous insulin infusion (CSII) in blood glucose control during the treatment of type 1 diabetes mellitus (T1DM) in children. under the nano-hydrogel delivery carrier. In order to improve the efficiency and therapeutic effect of the experiment, this paper adopts injectable nanomaterial-polymer composite hydrogel as drug delivery system to cooperate with insulin injection to improve the effective utilization of drugs. Eighty children diagnosed with T1DM by the department of Endocrinology, Genetics, and Metabolism of INNER MONGOLIA BAOGANG Hospital from October 2018 to December 2019 were selected as research subjects for this study. The children were randomly divided into MDI group (treated with MDI) and CSII group (treated with CSII), with 40 children in each group. The basic data of the children were compared, and changes in hemoglobin A1c (HbA1c) at admission and 1, 2, and 3 months after treatment were detected. During the detection, the blood glucose level, therapeutic time of blood glucose normalization, and daily insulin dosage were recorded. The HbA1c and fasting blood glucose (FBG) were followed up three months after discharge, and incidences of hypoglycemia in the two groups were observed. The results showed that the mean value of HbA1c in the MDI group was higher than that in the CSII group (P < 0.05). Each patient was assessed for the number of times their blood sugar was allowed to dip below normal levels; patients with less hypoglycemia had a higher rate of blood sugar control. The control rates of blood glucose in the MDI and CSII groups were 19.21% and 23.50%, respectively. The CSII group showed significantly higher blood glucose rates than the MDI group (P < 0.05). The therapeutic time of blood glucose normalization in the MDI group was significantly longer than that in the CSII group (P < 0.05). There was no significant difference in the average daily insulin dosage between the MDI and CSII groups (P > 0.05), which indicated that CSII therapy had significant advantages in reducing blood glucose in children with T1DM.
