Session Objectives (cont...) Investigate appropriately a patient with DM. Advice initial management plan for a patient diagnosed first with DM. Discuss different medication used in DM management. Identify importance of life style changes in diabetic patients. Discuss screening criteria for DM.
Genetic predisposition IGT Insulin Resistance (Hyperinsulinemia) Cell Defect Usually 50% of cells are functioning at time of diagnosis Type 2 Diabetes
Prevalence of DM in Saudi Arabia A community based study of subjects conducted between 1995 and 2000 in KSA. The examining age group, years of selected households during 5-year period Mansour M. Al-Nozha et al,The prevalence of CAD among Saudis of both sexes, in rural as well as urban communities, as well as modifiable risk factors for CAD. Saudi Medical Journal 2004; Vol. 25 (9):
Prevalence of DM in Saudi Arabia The overall prevalence of DM obtained from this study is 23.7% in KSA. The prevalence in males and females were 26.2% and 21.5% respectively (p< ). A large number of diabetics 1116 (27.9%) were unaware of having DM. Mansour M.

INCRETINS مجموعه ادويه جديده تعمل على هذا الانزيم - مهمه
Glucose in Intestine DPP-4 Plasma Mixed Meal Active Incretins Stimulate B cells (Pancreas) to secrete Insulin Inactive Incretin Renal Clearance
Physiological effects of GLP-1 Bunck MC, et al. Diabetologia. 2010;53 (Suppl 1):S338.
Glucagon-like Peptide-1 (GLP-1) مهمه شريحه GLP-1 is secreted throughout the day by intestinal mucosa in response to oral glucose in the gut. GLP-1 causes anabolic actions on the synthesis of insulin in beta cells by stimulating all steps of insulin biosynthesis. GLP-1 provides continued and augmented release of insulin for secretion in response to glucose without overproduction that could lead to hypoglycemia. GLP-1 also acts on islet alpha cells, causing strong inhibition of postprandial glucagon secretion. GLP-1 slows gastric emptying and acts on brain to promote early satiety with reduced food intake عيب هذا العلاج الذي يعمل على هذا الانزيم انه يؤخذ على شكل ابر – مهمه
Dipeptidyl Peptidase-4 (DPP-4) Within minutes of secretion or exogenous administration, GLP-1 is rapidly degraded by dipeptidyl peptidase-4 (DPP-4). DPP-4 is found in many body tissues, including liver, renal, and intestinal brush- border membranes; lymphocytes; and endothelial cells.
INCRETINS The incretin system is impaired in patients with T2DM, which, as a consequence of its insulinotropic actions, contributes to fasting and postprandial hyperglycemia. The impairment of GLP-1 secretion varies directly with the degree of insulin resistance; those who are more insulin resistant have a lower rise in GLP-1 in response to a meal.
Medication: ● Exenatide: GLP-1 receptor agonist, SC, twice-daily ● Liraglutide: GLP-1 analog, SC, once daily ● Sitagliptin (Januvia), (DPP-4) inhibitor, 100 mg OD Other DPP-4 inhibitors, Vildagliptin, Saxagliptin, … Type 2 diabetes only Monotherapy or with Metformin or TZD Weight neutral Does not cause hypoglycemia
Which antidiabetic Drugs are contraindicated or should be only مهمه very cautiously when the following Co-Morbidity is present? Chronic Kidney Failure: Metformin, Acarbose, Sitagliptin, Insulin & SUs (reduced dosage) Heart Failure: TZDs Osteoporosis: TZDs Myocardial Infarction: Hypoglycemias should be avoided when Insulin or SUs are taken. Elderly people (>70 years): Hypoglycemias should be avoided when Insulin or SUs are taken.
Indication of Insulin in Type 2 DM مهمه If HbA1c is ≥ 9 % After maximum metformin and suphonylurea, you should consider adding Insulin and taper the Sulphonylurea.
Initiation of Insulin Therapy in DM2 Complete Replacement Keep Metformin + Basal + Bolus insulin Add on Basal insulin at bed time + oral medication Types of Insulin Basal insulin (NPH, Glargine ( Lantus مهم ), Levimir) طويل التاثير يعطى مره واحده قبل النوم – يوضح بالرسومات لاحقا Premixed insulin (70/30, 75/25, 60/40, 50/50) Prandial insulin (bolus) Regular, Lispro, Aspart, NovoRapid SMBG
Initiation and Adjustment of Insulin≥ A1C 9% Long acting insulin (Basal) at bedtime 10 U or 0.2 U/Kg Check FG daily, increase by 2 – 4 U every 3 days until FG 70 – 130 mg/dl (3.9 – 7.2 mmol/L) if FBS > 250 mg/dl by 4-8 U. If hypoglycaemia occurs, or FG < 3.9 reduce bedtime by 4 units or 10 % which is greater If FG in range check before lunch, dinner and bedtime, add second injection. Begin with 4 -6 U of Bolus insulin before each. Adjust by 2-4 U every 3 days. Pre-bed is high add bolus insulin at dinner Pre-dinner is high add NPH at breakfast or bolus insulin at lunch Pre-lunch is high, add bolus insulin at breakfast

Glargine / Lispro Avoids fasting hyperinsulinaemia and hypoglycemia Can mimic pancreatic ß- cell insulin secretion 36% had hypoglycemia vs 50% on NPH. Glargine 50% and Lispro 50%
Hypoglycemia Treatment Check BG if possible. If <70 mg/dL… Rule of Give 15 grams of fast acting CHO: 3-4 glucose tablets, 1 Tb spoon honey, 3-4 sugar packets, 1 cup of milk, 5-6 hard candies,…. Wait 15 minutes and retest. If still low take additional 15 grams of CHO 15 grams should increase Blood Glucose about mg Glucose level treatment: mg/dl and alert 15 grams CHO mg/dl and alert 30 grams CHO < 30 mg/dl and alert 45 grams CHO Glucagon should be prescribed for all individuals at significant risk of severe hypoglycemia.
Antiplatelet agents ● ملخص السلايد ان المريض ما يعطى اسبرين الا اذا كان عنده احد المشاكل المذكوره بالسلايد – اذا ما عنده مشاكل ما يحتاج Consider Aspirin therapy (75–162 mg/day) as a primary prevention strategy in those with type 1 or type 2 diabetes at increased cardiovascular risk (10-year risk 10%). This includes most men 50 years of age or women 60 years of age who have at least one additional major risk factor (family history of CVD, hypertension, smoking, dyslipidemia, or albuminuria).
Statins and Diabetes Statin therapy should be added to lifestyle therapy, regardless of baseline lipid levels, for diabetic patients: with CVD. (A) without CVD who are over the age of 40 years and have one or more other CVD risk factors. (A)
Statins and Diabetes Low risk patients (without CVD and age of < 40) Statin therapy should be considered in addition to lifestyle therapy: if LDL cholesterol remains above 100 mg/dl or with multiple CVD risk factors.
Hypertension and Diabetes Goal: < 130 / 80 Choice of Medication: ACE inhibitors Angiotensin Receptor Blockers (ARP)
Influenza vaccine (yearly) Pneumococcal vaccine (once in lifetime) Vaccination
UKPDS قراءه Aim: To determine whether intensified blood glucose control with either sulfonylurea or insulin reduces the risk of Macrovascular or Microvascular complications in type 2 diabet.

◙ May 27, 2009 — A new meta-analysis suggests that intensively controlling blood glucose levels (HbA 1c ) to < 7.0%, significantly reduces the risk of (MI) and (CHD) events and has no effect on all-cause mortality and Stroke. The findings include UKPDS, ADVANCE, VADT, ACCORD, and PROACTIVE studies. ◙ The concerns stemmed particularly from the (ACCORD) and (ADVANCE) and (VADT) which showed no significant response on Macrovascular outcomes. ◙ ACCORD, on the other hand, was stopped early because of an increased risk of death in patients who underwent intensive blood glucose lowering.

TREATMENT REGIMENS OF TYPE 1 DM Conventional Insulin Therapy Two injections of NPH and Regular Insulin Mixed Insulin Two injections of 70/30 or 60/40 or 50/50 Multiple Insulin Injections ►1 or 2 injections of NPH plus 3 injections of Regular or Lispro Insulin. ►One injection of Glargine or Detemir plus 3 injections of Regular or Lispro Insulin.
INSULIN GLARGINE (LANTUS) The first clear long-acting insulin Acidic (pH of 4) when injected it is neutralized by the body, causing Glargine crystals to be precipitated and slowly absorbed. It is taken once a day Being acidic, cannot be mixed with other insulin
Initiation and adjustment of insulin regimens Long acting insulin at bedtime 10 U or 0.2 U/Kg Check FG daily, increase by 2 – 4 U every 3 days until FG 70 – 130 mg/dl (3.9 – 7.2 mmol/L) HbA1C ≥ 7% after 2-3 months If hypoglycaemia occurs, or FG < 3.9 reduce bedtime by 4 units or 10 % which is greater If FG in range check before lunch, dinner and bedtime, add second injection. Begin with 4 U before each. Adjust by 2 U every 3 days. Pre-bed is high add rapid acting insulin at dinner Pre-dinner is high add NPH at breakfast or rapid acting at lunch Pre-lunch is high, add rapid acting insulin at breakfast
Insulin administration Do not mix Glargine with other insulin products. Insulin site should be clean, but wiping with alcohol is not needed. Syringe reuse acceptable but meticulous attention to cleanliness is needed. Insulin pens improve the dose accuracy. Injection site rotation reduces the lipoatrophy. Abdomen region has a faster absorption rate than the Arm, which is faster than the leg.
