  1. Pediatric Type 1 Diabetes Mellitus Chelsea Stegman and Kelly Davis

  2. Test your Knowledge Type 1 Diabetes Mellitus is a/an _____ disease. a. Thyroid b. Bacterial c. Viral d. Autoimmune

  3. Test your Knowledge Type 1 Diabetes is most commonly diagnosed amongst: A. Overweight adults B. Children and adolescents C. Overweight children and adolescents

  4. Type 1 Diabetes • Most often diagnosed in children, adolescents, or young adults. • Causes of type 1 diabetes are complex and still not completely understood but type 1 diabetes can not be prevented. • People with type 1 diabetes are thought to have an inherited or genetic predisposition to developing the disease • The disease process is believed to be stimulated by an environmental trigger such as a virus, toxin, drug or chemical

  5. Type 1 Diabetes: Etiology • T1DM is characterized by the autoimmune destruction of beta cells. • Patients with type 1 diabetes produce little or no insulin via beta cells due to this destruction. • Insulin is a hormone produced in the pancreas by beta cells. • Insulin is needed to move blood sugar, glucose, into the cells where it is stored and later used for energy. • Without using insulin, glucose builds up in the bloodstream instead of going into the cells. • The body is unable to use this glucose for energy, which leads to the symptoms of type 1 diabetes.

  6. Symptoms: • Extreme thirst • Frequent urination • Drowsiness • Sugar in urine • Sudden vision changes • Increased appetite • Sudden weight loss • Fruity, sweet, or wine-like odor on breath • Heavy, labored breathing • Stupor and unconsciousness

  7. Diabetic Ketoacidosis • Severe Hyperglycemia • Most commonly found in patients with T1DM • Individuals experiencing DKA experience weight loss due to decreased blood volume (hypovolemia) and muscle metabolism • Precipitating factors include: • Lack of blood glucose self monitoring • Severe illness/infection • Increased insulin needs with growth spurts • Inappropriately stored insulin

  8. Diagnostic Measures: • Symptoms of diabetes plus casual plasma glucose concentration greater than/ equal to 200 mg/dL • Fasting plasma glucose greater than/ equal to 126 mg/dL • 2- hour post-prandial glucose greater than/ equal to 200 mg/dL during an oral glucose tolerance test (OGTT)

  9. Diagnostic Measures: T1DM • Islet Cell Cytoplasmic Autoantibodies (ICA antibodies) • Glutamic Acid Decarboxylase Autoantibodies (GADA antibodies) • Insulin Autoantibodies (IAA) • If an autoimmune disease is present in the family, their first-degree family members may be at risk for developing the same or different autoimmune disease. • Generally, T1DM is a childhood onset disease

  10. Patient: Rachel Roberts • 12 year old female • 7th grade • Height: 5’ 60 in • Weight: 82 lbs 70 kg • BMI: 16.0 kg/m2 • IBW: 89 lbs • Upon hospital admittance: acute-onset hyperglycemia • Serum glucose 724 mg/dL • Chief Complaints: Increased thirst, increased urination, slight weight loss • Diagnosis: Type 1 Diabetes Mellitus

  11. Abnormal Lab Values:

  12. Rachel’s Diagnosis • Rachel was diagnosed with T1DM due to: • Her symptoms of unexplained weight loss, polyuria, and polydipsia. • A serum glucose level of 724 mg/dL upon ER assessment (above 200). • The presence of B-cell destroying autoantibodies ICA, GADA, and IAA. • Low C-peptide levels, indicative of low insulin secretion. • There is a history of autoimmune diseases in her family. Her mother hyperthyroidism and her sister has Celiac’s disease.

  13. Rachel’s Nutritional Diagnosis • PES Statement 1:Altered nutrition-related lab values (NC 2.2) related to Type 1 Diabetes Mellitus as evidenced by a blood glucose concentration of greater than 110 mg/dL. • PES Statement 2: Unintended weight loss (3.2) related to inadequate insulin due to Type 1 Diabetes as evidenced by a reported weight loss of 8 lbs.

  14. Pharmacological Treatment • A physician prescribes a type of insulin, insulin dosage, and insulin regimen per individualized case. • Rachel is prescribed a combination of Apidra prior to meals with glargine given in the a.m. and p.m. Both are administered via insulin injection • Prescribed discharge dosages: 7 u glargine with Apidra prior to each snack, which is a 1:15 insulin: carbohydrate ratio.

  15. Justification of Prescription • Injection is used because oral pills are only used with Type II Diabetes. • The lower dosage of insulin is due to the temporary “honeymoon” phase. • honeymoon phase: relative self-sufficient insulin production after T1DM is clinically diagnosed and insulin treatment is initiated. • Glargine is given in the a.m. and p.m. for maintenance of the “dawn phenomenon” that Rachel is experiencing. • dawn phenomenon: consistently high blood glucose levels in the morning. This is a result of the lack of insulin injections while the individual is sleeping.

  16. Types of Insulin • Glargine • Onset of action: 2-4 hours. • Peak of action: peakless. • Duration of action: 20-24 hours. • Apidra • Onset of action: 5-15 minutes. • Peak of action: 30-90 minutes. • Duration of action: 3-5 hours.

  17. Treatment: MNT • Daily kcals: 2400-2500 • 15-20% of kcals from protein • 25-35% kcals from fat • 50-60% kcal from carbohydrates. Insulin should be taken accordingly to eliminate unsafe postprandial glucose responses. • Insulin Carbohydrate Ratio (ICR)- 1:15 • Patient and parents are educated on the importance of carbohydrate counting and are given literature on carbohydrate counting.

  18. Treatment: MNT • Rachel’s active lifestyle should also be taken into account [she is a soccer player] • Blood glucose levels should be monitored before and after exercise to recognize hypoglycemic or hyperglycemic conditions. • She should consume an additional 15 g of carbohydrates for every hour of moderate physical activity and 30 g for every hour of strenuous activity. • She will not have a decrease insulin dosage levels prior to exercise because of the regularity of her exercise regimen.

  19. Prognosis • T1DM cannot be cured, yet it can be managed. • Prescribed insulin doses will most likely increase based on the transitory nature of the current “honeymoon” phase. • Self monitoring of blood glucose should be done at home. • Purpose: to identify patterns and the ways in which food, exercise, and other factors affect glycemic control. • Method: a drop of blood obtained via a finger prick is applied to a chemically treated reagent strip. • This is recommended at least three times daily because hypoglycemia and hyperglycemia are dangerous conditions. Rachel and her family should be cognoscente of symptoms of hypoglycemia: rapid heartbeat, weakness, shakiness, perspiration, and hunger.

  20. Prognosis Continued • Rachel should attend routine follow-up visits with her physician and dietitian to analyze laboratory values, diet logs, and adherence to glycemic goals. • Microvascular and macrovascular complications generally occur 15-20 years after the onset of T1DM. • She is also at risk for nephropathy, retinopathy, and nervous system damage. • The incidence is reduced through intensive treatment and strict adherence to insulin regimens to prevent hypoglycemia or hyperglycemia.
