Peds DM2 Flashcards
Name 4 typical symptoms of DM2
- slow and insidious onset

Overweight and 2/3 of the following
- family history in 1st or 2nd degree relative
- minority race
- signs of insulin resistance (acanthosis nigrans, HTN, dyslipidemia, PCOS)
What labs other than BG suggest DM2?
- elevated fasting C-peptide
- elevated fasting insulin
- absence of autoimmune markers (glutamic decarboxylase and islet cell antibodies)
Name 3 urine tests for albuminuria.
- random spot albumin-creatinine ratio
- 24 hour collection for albumin and creatinine, alson allows for simultaneous creatinine clearance

True- early onset DM2 appears to be more aggressive from a cardiovascular standpoint
What does basal insulin do?
suppresses lipolysis, proteolysis, and glycogenolysis
What dose first-phase insulin secretion do?
facilitates the peripheral use of prandial nutrient load, suppresses hepatic glucose production, and limits postprandial glucose elevations

first phase
What is the basis for the progression from impaired glucose tolerance to DM2?
failure of the beta cells to keep up with the peripheral insulin resistance

every 2 years
What is the preferred screening tool?
fasting plasma glucose
What should you do if there is high suspicion for DM but fasting BG <100?
Oral glucose tolerance test
How often should you perform a dilated eye exam?
At onset and then every year
What is microalbuminuria?
-urinary albumin excretion of 30mg/24hr
T/F
2013 AAP guidelines recommend treating all patients who present with ketosis or extremely high BG with insulin
True - it may not be clear whether these patients have type 1 or type 2
When should you transition from oral agents to insulin?
In symptomatic patients with persistent hyperglycemia and HbA1c > 9% or ketoacidosis
T/F
Patients with PCOS that are treated with metformin may resume normal menstrual cycles and become pregnant
True
What is the first line medication?
Metformin if not controlled by lifestyle and HbA1c < 9%
What is the next drug added after Metformin?
insulin, sulfonylurea, or another agent
When should you start a statin?
When LDL goal are not met after 3-6 months of lifestyle modification
What should you use to treat HTN and microalbuminuria?
ACE
What is step 1 medication?
Metformin 1000-2000 mg/d
What is step 2 medication?
if step 1 not achieved after 3 mo, add 0.4-0.6 U/kg of 24 hour insulin at bedtime (Glargine or Levemir)
What is the BP goal for pts with HTN and DM or renal disease?
130/80

fibric-acid derivatives, bile acid sequestrants, niacin, ezetimbe
What 2 medications are approved by the FDA for children?
Metformin and insulin degludec (Tresiba)
How does metformin work?
- reduce hepatic glucose production
2. increase peripheral insulin sensitivity
T/F
A common side effect of metformin is hypoglycemia
False - metformin rarely induces hypoglycemia
T/F
Patients started on metformin tend to gain weight
False - because of its anorexigenic effects, many treated maintain or lose weight
Can metformin be used in renal or hepatic insufficiency or decompensated CHF?
No, this is due to and increased risk for lactic acidosis
