When To Start Insulin in T 2 DM • Patients with – hyperglycemic emergencies – symptomatic hyperglycemia and/or markedly high Hb. A 1 c – hepatic or renal disease – coronary artery disease, ↑ triglyceride level • • When combination oral/injectable agents become inadequate Unacceptable side effects of oral/injectable agents Patient wants more flexibility Special circumstances (ie, steroid use, infection, pregnancy) Holman RR, et al.

Efficacy and Safety of Analog vs RHI Prandial Insulin Injections —Meta-Analysis Key Findings • Greater Hb. A 1 c reduction (0. 1%; P=. 037) • Greater 2 -h PPG reduction at breakfast and dinner (≈ 10 -12 mg/d. L; P<. 001) • Possibly less frequent severe hypoglycemia (ORMH = 0. 61; P=NS) Meta-analysis of 13 trials of 4361 individuals with T 2 DM. Mannucci E, et al. Diabetes Obes Metab. 2009; 11: 53 -59. Conclusions • Prandial analogs have slightly greater efficacy and possibly less risk of severe hypoglycemia than RHI • Comparative efficacy analyses among prandial insulin analogs are not possible with available data

Basal-Plus Mealtime Insulin • Use rapid-acting analogs (Aspart, Lispro, Glulisine), not RHI – Easier timing, less postprandial hypoglycemia • Start with 1 injection at largest meal: – 4 units and titrate, OR – By weight: 0. 1 unit/kg • Titrate to: – < 140 mg/d. L 2 hours postprandial OR – < 110 mg/d. L next meal or bedtime Garber AJ, et al. Endocr Pract. 2016; 22: 84 -113.
Basal-Plus Mealtime Insulin (cont) • Consider decreasing dose or stopping oral secretagogues • Can continue metformin, TZD, AGI, GLP-1 RA, DPP-4 i • Basal-bolus dosing – ~50% basal insulin and ~50% bolus insulin Garber AJ, et al. Endocr Pract. 2016; 22: 84 -113.
Quality of Life Improves in T 2 DM With Intensification of Insulin Therapy • Multicenter study of 447 patients with insulin-treated T 2 DM and Hb. A 1 c >7% • Patients were transitioned from baseline insulin regimens to basal -bolus using glargine + rapid-acting insulin – Hb. A 1 c declined from 8. 8% to 7. 7% over 6 months (P <. 001) – Nonsevere hypoglycemic episodes decreased • Small but significant improvements with no significant change in hypoglycemia fear – Emotional well-being (P<. 001) – Diabetes symptom distress (P<. 001) – Hypoglycemia fear (P=. 61) Hajos TR, et al. Qual Life Res. 2012; 21: 1359 -1365.

Inhaled Human Insulin • Limitations of use – Adults – In T 1 DM, use with basal insulin – Not for diabetic ketoacidosis, persons who smoke • Contraindicated in chronic lung disease – Assess lung function prior to and during treatment • Hypokalemia- monitor at-risk persons • Fluid retention/Heart failure with concomitant TZD • Most common adverse events – Hypoglycemia, cough, throat pain/irritation Afrezza [package insert].
