Diabetologia 2009;52:17−30 Summary: Treatment of DM in CKD Novel diabetic medications are available in past few years. Some require adjustment of dose or should be even avoided according to the patient’s renal function. Metformin, 1st line Tx in patients with normal renal function, is contraindicated in CKD with Cr>1.5 (M) or 1.4 (F) mg/dL. CKD stage 3/4: SU (glipizide, gliclazide, glimepiride), Glinides, TZD, DPP4i, α-glucosidase inhibitor, insulin CKD stage 5 or ESRD: SU (glipizide, gliclazide), Glinide (repaglinide, mitiglinide), TZD, DPP4i, insulin Judicious titration of medications and frequent monitoring of blood glucose to avoid severe adverse effects! Summary for Basal Insulin Therapy Tight glycemic control reduces risk of complications. Earlier initiation of insulin helps achieve target of glycemic control. Lantus, long-acting insulin analog, as a basal insulin therapy with: – Once daily, peakless, 24 hours basal insulin – Consistent efficacy in glycemic control – Less hypoglycemia than NPH insulin and premixed human insulin – Less adverse reactions than TZD add-on to OADs – Easy titration according to FPG to achieve target Paradigm 512™ Paradigm Link™ Wireless Diabetes Managing System: Insulin Pump (Paradigm 512) and Blood Glucose Monitor (Paradigm Link) 74 Thank You for Your Attention!
