Prediabetes
A pt w/ HbA1c of 5.7-6.4% is concerning for what?
Prediabetes
The continuum of risk for DM is curvilinear. What does this mean?
As glucose measurements/ A1c rises, DM risk rises disproportionately
Prediabetes places you are increased for what two diseases?
DM and CV disease
When is metformin considered for a prediabetic pt? (3)
If BMI ≥ 35 age < 60 women w/ prior GDM
What is the first line tx for prediabetic pt?
Life style modification (education, preventions, behavior lifestyle intervention, weight loss)
What form of diabetes is due to an absolute insulin deficiency?
Type 1 DM
What form of DM is due to an autoimmune destruction of B-cell, resulting in presence of islet cell and/or GAD-65 Ab?
Type 1 DM
If pt is prediabetic, how often do you need to test for development of T2DM?
Annually
In a prediabetic pt, what disease must you also screen for and tx?
ASCVD (screen annually, used 10 yr risk calculator)
Is the rate of B-cell destruction in T1DM pt the same for each pt?
No, it is variable
T1DM is most common in what ages?
Children and young adults
Is a pt with T1DM at risk for other autoimmune disorders?
Yes (thyroid disease, celiac disease, pernicious anemia)
What is the classic triad of T1DM?
Polyuria, polydipsia, polyphagia
DKA is more common in T1 or T2DM?
T1
Weight loss, nocturia and blurry vision are sx associated with T1 or T2DM?
T1
Is T1 or T2DM most common?
T2 (90-95%) T1 (5-10%)
Does T2DM develop quickly or gradually?
Gradually
Obesity, specifically in what area of the body, is associated with an increased risk of DM?
Visceral/abdominal obesity
Hyperglycemia, insulin resistance and relative insulin deficiency are characteristics of what form of DM?
T2DM
Insulin resistance impair glucose utilization by insulin sensitive tissues. What does this result in?
Results in increase insulin production
What happens to the B-cell mass over time in pts w/ T2DM?
B-cell failure (burnout)
Polyuria, polydipsia, nocturia, and blurry vision are sx of what form of DM?
T2DM
Chronic skin infections/poor wound healing, genital yeast infections, and acanthosis nigricans are sx of what form of DM?
T2DM
Who do you screen for for T2DM? (2)
- All adults @ 45 y/o 2. BMI ≥ 25 & 1 RF
What are the four risk factors for T2DM?
- Positive family history 2. HTN (≥140/90 or on meds) 3. dislipidemia (HDL < 35 or TG > 250) 4. severe obesity
If diabetes screen is normal. At what yearly minimum should you retest the pt?
3 year intervals (consider more frequent testing if increased risk factors/initial test results)
All DM pts should receive what during their during the annual exam?
Comprehensive foot exam
What vitamin level should oyu check in pts w/ DM?
Vit. B 12
Results of what test might be skewed by anemia/ hemoglobinopathies (high RBC turnover), race, or pregnancy?
HbA1c
Fasting plasma glucose <100 is normal, prediabetic or DM?
normal
Fasting plasma glucose 100-125 is normal, prediabetic or DM?
Pre-DM
Fasting plasma glucose ≥126 is normal, prediabetic or DM?
DM
Oral glucose tolerance <140 is normal, prediabetic or DM?
normal
Oral glucose tolerance 140-199 is normal, prediabetic or DM?
pre-DM
Oral glucose tolerance ≥200 is normal, prediabetic or DM?
DM
HbA1c < 5.7% is is normal, prediabetic or DM?
normal
HbA1c 5.7-6.4% is is normal, prediabetic or DM?
pre-DM
HbA1c ≥6.5 % is is normal, prediabetic or DM?
DM
DX of DM requires what?
Requires two abnormal testsfrom the same sample or two separate test samples
If asx pt is tested for DM and OGTT is 180, but HbA1c is 6.5% can you dx pt w/ DM?
No. Need to recheck the lower lab value. *DX Requires two abnormal test from the same sample or two separate test samples
If pt resents with classic DX sx and random plasma glucose 200 can you dx pt w/ DM?
Yes
What is the leading cause of morbidity and mortality in DM pts?
ASCVD/Macrovascular complications (CHD, cerebrovascular disease, PAD, HF) (DM pts are 2x more likely to die of stroke of MI vs those w/o DM)
DM is an independent RF for what disease?
ASCVD (= leading cause of morbidity and mortality in
What is the tx to prevent macrovascular complications in DM pts? (4)
Lifestyle mod, BP control, lipid management, antiplatelets (aspirin, clopidogrel)
Diabetic kidney disease is aka what?
Nephropathy
T or F: DM is the leading cause of renal failure in the US?
TRUE
A clinical Dx of DM nephropathy is supported by what findings? (2)
Albuminuria and/ or reduced GFR (in the absence of signs/ sxs of other primary causes of kidney damage)
DM pts should be screened annually for nephropathy. What two things do you need to measure?
- urinary albumin-to-creatinine ratio (UACR) - 2-3 specimens of UACR collected within 3-6 month period should be abnormal before considered albuminuria 2. eGFR
