Abstract
Objective. Evaluation of the impact of deintensification of the basal-bolus insulin therapy (BBIT) regimen and premixed insulin therapy (PMIT) in elderly patients with type 2 diabetes mellitus (DM2) on glycemic control, hypoglycemic events, functional and cognitive status.
Methods. A prospective, observational, uncontrolled study included 44 DM2 patients (Me age 70.5 [67–75] years) on BBIT or PMIT in combination with oral hypoglycemic agents or glucagon-like peptide-1 receptor agonists (PMIT +/- OHA/GLP-1RA) who discontinued bolus insulin and continued therapy with basal insulin preparations in combination with AHA and/or GLP-1 AR. An examination according to the algorithms for providing medical care to diabetic patients and comprehensive geriatric assessment were conducted.
Results. After deintensification of insulin therapy, the insulin dose decreased from 58 U [47–75] to 31 U [22–50] (p=0.001), the HbA1c level did not change: 8.7 [7.7–10.2]% vs. 8.8 [7.9–10.1]% (p=0.542). The proportion of patients experiencing mild hypoglycemia decreased from 67.6% to 32.6% (p=0.003), the frequency of mild hypoglycemia decreased from 1 [0–4] to 0 [0–2] per 1 patient (p=0.001). BMI decreased from 31.2 kg/m2 [27.55–36.75] to 30.5 kg/m2 [26.25–35.65] (p=0.005). The time to complete the Stand and Go test decreased from 10.6 sec [8.5–12.0] to 8.0 sec [7.0–9.0] (p=0.02). The proportion of patients with risk of falls decreased from 54.3% to 17.1% (p=0.02). The functional and cognitive status of patients did not change.
Conclusions. Deintensification of insulin therapy by discontinuing bolus insulin in elderly patients with type 2 diabetes mellitus reduced the incidence of hypoglycemic events without worsening glycemic control, led to weight loss, and was associated with an increase in walking speed and a decrease in the risk of falls.
