Here, we review insulin management options and strategies in nonpregnant adult patients with type 1 diabetes mellitus (T1DM). Most patients with T1DM should follow a regimen of multiple daily injections of basal/bolus insulin, but those not meeting individual glycemic targets or those with frequent or severe hypoglycemia or pronounced dawn phenomenon should consider continuous subcutaneous insulin infusion. The latter treatment modality could also be an alternative based on patient preferences and availability of reimbursement. Continuous glucose monitoring may improve glycemic control irrespective of treatment regimen. A glycemic target of glycated hemoglobin < 7% (53 mmol/mol) is appropriate for most nonpregnant adults. Basal insulin analogues with a reduced peak profile and an extended duration of action with lower intraindividual variability relative to neutral protamine Hagedorn insulin are preferred. The clinical advantages of basal analogues compared with older basal insulins include reduced injection burden, better efficacy, lower risk of hypoglycemic episodes (especially nocturnal), and reduced weight gain. For prandial glycemic control, any rapid-acting prandial analogue (aspart, glulisine, lispro) is preferred over regular human insulin. Faster-acting insulin aspart is a relatively new option with the advantage of better postprandial glucose coverage. Frequent blood glucose measurements along with patient education on insulin dosing based on carbohydrate counting, premeal blood glucose, and anticipated physical activity is paramount, as is education on the management of blood glucose under different circumstances.Plain Language Summary: Plain language summary is available for this article.

BACKGROUND: Glucose variability combined with glycosylated hemoglobin (HbA1c) assessments more reliably represents the level of glycemic control. The study was aimed to compare blood glucose variability with insulin glargine vs. neutral protamine Hagedorn (NPH) in patients with type 2 diabetes mellitus using a continuous glucose-monitoring system (CGMS), in patients treated with basal insulin using stable dose of oral antidiabetic agents and HbA1c in the range of 4.5-8.0 % International Federation of Clinical Chemistry (IFCC) units. [6.2-9.4 % Diabetes Control and Complications Trial (DCCT) units]. METHODS: This was a multicenter, prospective, open-label, single-arm study in patients (N = 116) treated for ≥ 2 months with NPH and metformin combined with sulfonylurea or glinide. Glucose variability was measured after a 4-week NPH treatment phase and after a subsequent 12-week glargine treatment phase using CGMS. Based on 72-hour CGMS, glucose variability was assessed by area under the curve [AUC (mmol/L · h)]. Differences (glargine-NPH) in AUC within 24 h in the glucose ranges of ≤ 3.3, ≤ 3.9, 7.5-3.9 (margins excluding), ≥ 7.5, ≥ 10, and ≥ 15 mmol/L were evaluated. Circadian fluctuation of glucose was assessed by M-value (log-transformation of the deviation from an arbitrary standard). RESULTS: AUCs of glucose in the lowest ranges (≤ 3.3 and ≤ 3.9 mmol/L) did not change significantly after treatment with glargine. Those in the higher ranges (≥ 7.5, ≥ 10, and ≥ 15 mmol/L) were significantly lower (p < 0.001 for all ranges), whereas AUC of glucose in the normal range (3.9-7.5 mmol/L) was significantly higher (p < 0.001) at the end of glargine treatment phase. Circadian fluctuation of glucose assessed by M-value showed a significant decrease after glargine treatment (p < 0.003). No significant differences in hypoglycemia confirmed by glucose value ≤ 3.3 mmol/L were found between treatment phases. This trial is registered at ClinicalTrials.gov, NCT00659477. CONCLUSIONS: As monitored by CGMS, switching from NPH to glargine with active titration shifted glucose from abnormally high to normal levels with reduced fluctuation and without increased risk of hypoglycemia.
