They slow or block the breakdown and absorption of carbohydrates and certain sugars thereby delaying entry of glucose into liver and muscle tissue. Side Effects include flatulence, diarrhea and abdominal pain. Hypoglycemia may result if taken with a secretagogue or insulin. The use of alpha-Glucosidase inhibitors is contra-indicated in patients with renal dysfunction, inflammatory bowel disease, colonic ulceration or cirrhosis. They should not be used in patients with serum creatinine levels >2.0 mg/dL. This class of medications is not used much in US. Generic and brand names for common Alpha-Glucosidase inhibitors include Precose for acarbose and Glyset for miglitol.Information about the long-term use of acarbose in patients with reduced kidney function is sparse and its use in patients with later stage 3 and stages 4 and 5 CKDis not recommended.

42 ADA-EASD Consensus Key messages on insulin - Insulin is the most effective drug in lowering BG- Insulin should be started with basal insulin- Basal Insulin is proposed as early as after Metformin- Then consider stepwise addition of bolus insulin starting with one shot at selected meal- Premixes are not recommended as first line insulin therapyThe following three-step approach to achieving and maintaining glycemic control is recommended. This graphic shows the relative glucose-lowering potential of all commonly used antidiabetes agents.Step 1 – initial therapy should be a combination of lifestyle intervention and metformin therapy. Metformin is the first-choice pharmacological intervention because of its efficacy, absence of weight gain and hypoglycemia, high level of acceptance, and low cost.Step 2 – additional therapy within 2–3 months of the initiation therapy or whenever HbA1c goal is not achieved. Basal insulin therapy should be considered for patients with HbA1c levels > 8.5% because insulin is the most effective glucose-lowering agent and can achieve reductions of up to 2.5%. Hospitalisation is not required to initiate insulin or adjust therapy. The patient is the key player and should be trained and empowered with the guidance of healthcare professionals.Step 3 – further adjustments to achieve glycemic targets. This involves initiation of basal insulin if not previously used or intensification of insulin therapy using prandial insulin to control postprandial glucose excursions. In some cases another oral agent may be added but this is often ineffective and can be relatively expensive.Nathan DM, et al.

72 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, insulinCKD stage 5 or ESRD: SU (glipizide, gliclazide), Glinide (repaglinide, mitiglinide), TZD, DPP4i, insulinJudicious titration of medications and frequent monitoring of blood glucose to avoid severe adverse effects!
73 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 insulinConsistent efficacy in glycemic controlLess hypoglycemia than NPH insulin and premixed human insulinLess adverse reactions than TZD add-on to OADsEasy titration according to FPG to achieve target

77 Relative Contributions of Diabetic Pathophysiologies Over Time Both beta-cell dysfunction + insulin resistance start years before diagnosisBeta-cell dysfunction determines the onset of hyperglycemia, glucose levels and disease progression, not insulin resistanceThose who develop DM have lost ~50% of beta-cell functionHepatic glucose over-productionRelative Contributions of Diabetes Pathophysiologies Over TimeThis is a conceptual slide about the relative contributions of diabetic pathophysiologies, beta-cell dysfunction, insulin resistance, and hepatic glucose overproduction.Build 1-From UKPDS, at the time of diagnosis of type 2 diabetes and 6 years afterwards about 50% and 73% of beta-cell function has been lost, respectively.1 This and other data2,3 has led to the projection that beta-cell dysfunction begins in individuals with normal glucose tolerance (NGT) more than 10 years before diagnosis.1 Beta-cell dysfunction is progressive with time.3,4Build 2-Insulin resistance, like beta-cell dysfunction, begins years before diagnosis4Build 3-Insulin resistance develops rapidly. It has been shown that there is no significant difference between the level of insulin resistance found in individuals with impaired glucose tolerance (IGT) and that found in type 2 diabetes patients.3 Although insulin resistance is known to drive metabolic deterioration in the development of type 2 diabetes, beta-cell dysfunction ultimately determines the onset of hyperglycemia and is a major factor associated with progressively rising plasma glucose levels and disease progression.3,5Basal hepatic glucose output did not differ significantly between NGT and IGT groups.6 It has been shown that during type 2 diabetes increases in hepatic glucose production correlate with the increases in fasting glucose levels.7100%Beta-cell dysfunction100%Insulin resistanceNGTIGTT2D DiagnosisLate Stage T2DMNGT = normal glucose tolerance, IGT = impaired glucose tolerance, T2D = type 2 diabetesBell D.
