Abstract:

Objective To investigate the effects of insulin-mediated lipohypertrophy (LH) on short-term glycemic variability of hospitalized diabetic patients treated with insulin pump. Methods A total of 232 inpatients with diabetes who received both short-term insulin pump therapy and dynamic blood glucose monitor were retrospectively analyzed, including 52 cases of type 1 diabetes mellitus (T1DM) and 180 cases of type 2 diabetes mellitus (T2DM). The incidence of insulin injection-related LH in patients with different types of diabetes was counted, and the differences in short-term glucose fluctuation indicators between patients with LH and those without LH were compared. The relationship between mean glucose fluctuation amplitude (MAGE) and clinical indicators was analysed. Binary Logistic regression was used to analyse the factors influencing glucose fluctuations. Results The overall incidence of LH was 61.2% in 232 patients, with 57.7% (30/52) in T1DM patients and 62.2% (112/180) in T2DM patients. In both T1DM and T2DM patients, MAGE was positively correlated with LH and negatively correlated with BMI, years of insulin use, and duration of diabetes (P < 0.05). Multi-factor Logistic analysis showed that LH was a risk factor for blood glucose fluctuations in both T1DM (OR= 4.665, 95%CI: 1.134-19.200) and T2DM (OR=6.659, 95%CI: 3.248-13.654) patients. Conclusion Insulin-mediated lipohypertrophy is identified as a vital risk factor for short-term glycemic fluctuations in diabetes.
