    FBG > 7 is DM, 6.1-7 IFG, <6 is normal
  33. What do you do if they are Impaired Fasting Glucose?
    • If IFG → do Oral Glucose Tolerance
    • Also, if borderline N with 1+ RF then do OGTT to look for IGT
  34. What is the DM Target Control? (for most diabetics)
    • A1C < 7%
    • FBG/preprandial 4-7mM
    • 2h pp BG – 5-10mM (lower to 5-8 if ↑A1C)

    HbA1C q3/12 then q1yr and decrease if at targets and stable
  37. How often to do CBGMs in DM?
    • At least 3x/d CBGM if using insulin – mainly to monitor hypoglycemia and commitment
    • If not on insulin – individualized, no evidence for it

    *Pneumovax and Influenza for all > 65 yr x 1 or DM I/II, then can repeat
  42. What is first line drug for DM?
    • Metformin (aka Glucophage) (covered) – weight neutral
    • 1st line, increases sensitivity to insulin, hard on liver and kidney
  43. What are the 2 mechanisms of action of metformin?
    2 MOA’s: liver → decreases GNG, peripheral - ↑ peripheral insulin sensitivity
  44. What are 2nd line drugs for DM?

    TZD (thio…. – Actos, Avandia) – used to be 2nd line, increased CVD risk, so don’t use
  46. What to guidelines say about high dose metformin vs low dose of metformin + insulin secretagogues?
    Guidelines don’t compare increased dose of 1 vs 2 low dose
  47. Under what circumstances should you start with Metformin on Dx of DM?
    1) Hb A1C ≥ 9% @ Dx, 2) Dx with HONK/DKA → start with metformin and 2nd drug (insulin or 2nd line Diabeta (secretagogue))

  51. What are diabetics risk for CVD?
    • Increased risk of CAD+ - macrovascular complications, occur 10-12 yrs before non-diabetics
    • But mostly if M> 45 and F > 50 or known MI/CAD, Microvascular complications, or + RF’s
  52. What is annual screening for patients with DM?
    • Urine albumin-Cr ratio (Urine ACR)
    • Dx CKD+ if GFR < 60 x 2 times 3 months apart
    • Or Urine ACR 2/3 abN of 3 ACR’s
  53. What is another microvascular complication besides kidney and what is the screening for it?
    • Retinopathy – optomitrist @ Dx, then q1-2 yrs
    • Occur in DM I – 5 yrs post Dx ie 17yrs then 22 yrs then q1y

    • Erectile dysfunction – ask about in all DM men
    • Follow guidelines
  57. How do you prevent CVD in DM?
    • Tx – vascular protection – lifestyle, weight loss/diet, bp, good glucose control
    • Tx bp if >130/>80
    • Renal protection – ACEI or ARB if proteinuria
    • Antiplatelet if high risk (ASA and statin)
