Treatment of Concominant Conditions Related to DM! (cont.)

 TREATMENT OF CONCOMINANT CONDITIONS RELATED TO DIABETES MELLITUS

  1. Coronary Heart Disease
  2. Dyslipidemia
  3. Hypertension
  4. HIV and AIDS
  5. Antipsychotic Therapy
  6. Hypoglycemia
  7. Diabetic Ketoacidosis (DKA)
  8. Hyperosmolar Hyperglycemic state
  9. Retinopathy
  10. Neuropathy
  11. Foot Ulcers 

3.HYPERTENSION

Uncontrolled blood pressure plays a major role in the development of macrovascular events as well as microvascular complications, including retinopathy and nephropathy in patients with Diabetes Mellitus.

Medications:

There are several other principles regarding the treatment of hypertension in Diabetes patients.

  • Angiotensin-converting enzyme (ACE) inhibitors or Angiotensin II receptor Blockers are recommended as initial therapy because of their beneficial effects on renal function.
  • Combination therapy with ACE Inhibitor and Dihydropyridine calcium channel blockers has shown to reduce cardiovascular morbidity and mortality versus those receiving ACE Inhibitor therapy combined with Thiazide Diuretic.
  • However, thiazide diuretics work synergistically with ACE Inhibitors and angiotensin II receptor blockers and can be added  on for those who fail to reach blood pressure goals with a single agent goal as long as the patients estimated glomerular filtration rate remains at 30mL/min/1.73m2 or higher.
  • Alternatively, a loop diuretic can be used.

Recommended Goals:

  • The ADA recommends that systolic blood pressure goals for patients with DM be individualized but generally set at less than 130mmHg. The diastolic blood pressure goal for patients with DM is less than 80mmHg.
  • It can be expected that most patients require more than one agent to reach blood pressure goal.
  • Renal function and serum potential levels should be monitored closely in all patients taking an ACE inhibitor, Angiotensin II receptor blocker and/or diuretic.

Contraindication:

    • ACE inhibitors and angiotensin II receptor blockers are contraindicated in pregnancy and in those with  bilateral renal therapy.`


4.HUMAN IMMUNODEFICIENCY VIRUS (HIV) and ACQUIRED IMMUNODEFICIENCY SYNDROME (AIDS)

  • Patients with risk factor for diabetes are more likely to develop diabetes when exposed to highly active antiretroviral therapy.
  • Universal screening for all HIV Patients for diabetes is controversial, but most clinicians support screening for those with risk factors, especially if those risk factors include positive family history and central adiposity.
  • Disturbances in glucose homeostasis are known side effects of protease inhibitor therapy.

Medications:

  • Indinavir and Ritonavir block insulin-mediated glucose disposal causing insulin resistance, but Amprenavir and Atazanavir have no effects on this pathway.
  • Indinavir also increases hepatic glucose production and release and causes insulin to lose its ability to suppress hepatic glucose production.
  • Nelfinavir, lopinavir and Saquinavir causes a 25% reduction in beta-cell function, reducing first-phase insulin release.

Contraindications:

  • Drug selection for treating protease inhibitors-induced hyperglycemia should address the mechanism behind the adverse effects.
  • Protease inhibitor therapy should be avoided in patients with pre-existing glucose abnormalities and in those with a first-degree relative with diabetes.
  • Metformin should be used with caution in patients taking the nucleoside reverse transcriptase inhibitors Stavudine, Zidovudine and Didanosine because of an increased risk for lactic acidemia.

5.ANTIPSYCHOTIC DRUG THERAPY

  • An association has been discovered between the second-generation antipsychotics and the development of diabetes.
  • Risk seems to be the highest with Clozapine and Olanzapine, but data are conflicting for Risperidone and Quetiapine.
  • Aripiprazole and Ziprasione for yet have no shown an increased risk for diabetes with their use.

Recommendations:

  • Nutrition and physical activity counselling is recommended for all patients with mental illness who are overweight or obese, especially if they are second generation anti-psychotics.
  • After the therapy, patients' weight should be assessed at weeks 4, 8, and 12 and then every 3 months.
  • In an event of increase in patients weight greater than or equal to 5%, of the patient's baseline weight, the therapeutic adjustment should be considered.
  • For patients who develop worsening glycemia or Dyslipidemia while on antipsychotic therapy, it is recommended that a switch to second generation antipsychotic with less weight gain or diabetes potential be considered.

General Mechanism of Actions of INSULIN.

GENERAL MECHANISM OF ACTION OF INSULIN AND RELATE HORMONES The body's main fuel is Glucose. Glucose is stored in the liver and muscles as Glycogen.  Excess glucose is stored in the adipose tissues which yield fatty acids via lipolysis. In the fasting state, free fatty acids supply much of the energy needs of the body except for the CNS which requires Glucose to function normally. Proteins can also be converted to glucose via gluconeogenesis. RELEASE OF INSULIN AND GLUCAGON Insulin and Glucagon are produced in the pancreas by the Islets of Langerhans . Beta cells   make up 70%-90% of the Islets and produce Insulin and Amylin while the a-cells   produce glucagon. The main function of insulin is to decrease blood glucose levels. Glucagon, along with other counter-regulatory hormones such as growth factor, cortisol, and Epinephrine, increases Blood glucose levels.  The opposing actions of Glucagon and Insulin along with other counter-regulatory hormones maintain a norma...

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 medicatio...

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...
