Diabetes Mellitus: Pharmacotherapy-Sulfonyl Ureas!

  PHARMACOTHERAPY Oral and injectable agents are available to treat patients with T2DM who are unable to achieve glycemic control through meal planning and physical activity. Medications classifications include:  Sulfonyl Urea's Nonsylfonylurea Secretagogues (a-Glinides) Biguanides Thiazolidinediones a-Glucosidase Inhibitors Dipeptidyl Peptidase-4 Inhibitors(Gliptins) Sodium-glucose co-transporter (SGLT) Inhibitors  Central-Acting Dopamine Agonists Bile Acid Sequestrants Insulin therapy SULFONYL UREAS Sulfonylureas represent the first class of Oral blood glucose lowering agents approved by the United States. These drugs are classified as either First- or Second-Generation drugs . Both classes of sulfonyl ureas are effective when given at equipotent doses. Mechanism of Action Sulfonyl ureas enhance insulin secretion by blocking ATP-sensitive potassium channels in the cell membranes of pancreatic beta cells. This action results in membrane depolarization, allowing the influx of cal

Data from randomized controlled trials seem to support the efficacy of Coc

Diabetes Mellitus: Non-Pharmacological Therapy--MNT!

 NON PHARMACOLOGICAL THERAPY  MNT Glycemic Index Dietary supplements Weight measurements Physical Activity Psychological assessment Immunizations 1. MEDICAL NUTRITION THERAPY (MNT)  " Medical Nutrition Therapy (MNT) is a term used by the ADA to describe the optimal condition of caloric intake with other aspects of diabetes therapy (Insulin, Exercise, Weight loss)". The ADA has issued recommendations for three types of MNT: Primary prevention measures of MNT are directed at preventing or delaying the onset of type 2 Diabetes in high-risk individuals (obese or with pre-diabetes) by promoting weight reduction. Secondary prevention measures of MNT are directed at preventing or delaying-related complications in diabetic individuals by improving glycemic control. Tertiary prevention measures of MNT are directed at managing diabetes-related complications (cardiovascular disease, neuropathy) in diabetic individuals. Despite the popular notion, there is not any " Diabetic diet

Diabetes Mellitus: Its Goals Of Therapy!

  GOAL OF THERPY The goals of treatment of DM includes; Reducing, controlling and managing long-term microvascular, macrovascular and neuropaathic complications. Preserving beta cell function. Preventing acute complications from increased Blood glucosel level. Minimizing hypoglycemic episodes. Maintaining patient quality of life. --Two landmark trials, THE DIABETES CONTROL AND COMPLICATION TRIAL (DCCT) and THE UNITED KINGDOM PROSPECTIVE DIABETES STUDY(UKPDS), showed that lowering blood glucose levels decreased the risk of developing chronic complications. --A near normal blood glucose level can be achieved with appropriate patient education , lifestyle modification and medications . --Proper care of DM requires goal setting and assessment for glycemic control , self-monitoring of blood glucose (SMBG) monitoring of blood glucose pressure , and lipid levels , regular monitoring for the development of complications , dietary and exercise lifestyle modifications and proper medication us

Diabetes Mellitus: Clinical Presentation and Diagnosis!

 CLINICAL PRESENTATION AND DIAGNOSIS OF DM 2. SCREENING American Diabetes Association (ADA) recommends routine screening for T2 DM every 3 years in all adults starting at 45 years of age. Testing of T2 DM should be considered in any adult, regardless of their age, who have a BMI greater than or equal to 25kg/m2. The ADA does not currently recommend widespread screening for T1 DM because of the relatively low incidence in the general population, although measurement of Islet antibodies may be appropriate for high-risk individuals. 3.GESTATIONAL DIABETES: "Gestational diabetes is the glucose intolerance in women during pregnancy". All pregnant women who have risk factors for T2 DM should be screened for undiagnosed T2 DM at their first prenatal visit using standard diagnostic criteria.  Any women found to have diabetes in the early point at pregnancy is considered to have T2 DM or GDM. All other pregnant women, not currently known to have DM should be screened for GDM with a 75

Diabetes Mellitus: Metabolic Syndrome and Role of Incretins!

  METABOLIC SYNDROME AND INCRETIN EFFECT METABOLIC SYNDROME: "Insulin resistance has been associated with a number of other cardiovascular risks , including Abdominal obesity , Hypertension , Dyslipidemia , Hypercoagulation , and Hyperinsulinemia . The clustering of these risk factors has been termed as Metabolic syndrome." The most widely used criteria to define metabolic syndrome were established by the National Cholesterol Education Program Adult Treatment Panel III Guidelines . INCRETIN EFFECT Incretins: are a group pf metabolic hormone that stimulate a decrease in blood Glucose levels. Incretin hormones are: GLP-1, GIP. Incretins are gut hormones that are secreted from entero-endocrine cells into blood within minutes after eating (present in GIT, Stomach, and Pancreas). A great deal of research is occurring today to develop compounds that enhance the incretin effect, either by mimicking its action or y enabling incretin hormones, to remain physiologically active for lon

Diabetes Mellitus: Pathophysiology

 PATHOPHYSIOLOGY OF DM IMPAIRED INSULIN SECRETION A pancreas with normal Beta cell function is able to adjust insulin production to maintain normal blood glucose levels. Hyperinsulinemia or high blood levels of insulin is an early finding of T2 DM. More insulin is secreted to maintain normal blood glucose levels until eventually the pancreas can no longer produce sufficient insulin. Impaired Beta cell function results in reduced ability to produce a first-phase insulin response sufficient to signal the liver to stop producing glucose after a meal. As DM progresses, large numbers of patients with T2DM eventually loses all beta cell function and require exogenous insulin to maintain the blood glucose levels.  INSULIN RESISTANCE Insulin resistance is the primary factor that differentiates T2DM from other forms of diabetes. Insulin resistance maybe present for several years prior to the diagnosis of DM. Insulin resistance occurs more significantly in skeletal muscles and liver. Insulin res
