Diabetes Kania Part 1

Question 1

Beta-cell-centric construct: Egregious Elevan

Answer 1

-Beta cells may be destroyed or simply quit working
-Diabetic patients have been shown to have decreased incretin effect, which normally helps stimulate insulin release
-Alpha cells in the pancreas can also dysfunction leading to an increase in glucagon
-Insulin resistance can occur in the tissue (adipose, muscle, and liver); obesity can increase risk
-Changes in levels of hormones that control appetite can lead to overeating and increased blood sugar; some hormone changes can increase insulin resistance
-Different gut bacteria can modify blood glucose levels and may decrease GLP-1 levels
-Autoimmune reaction and increased inflammation can destroy beta cells
-Quick stomach emptying can lead to increased glucose absorption
-Upregulation of SGLT2 can lead to increase glucose reabsorption in the kidney

Answer 21

Initiate metformin especially in:

Question 32

What to use to treat microalbuminuria in diabetic patients

Answer 32

-ACE1 or ARB is strongly recommended for non-pregnant patients with UACR 300 or more or a eGFR less than 60
-Preferably use SGLT2I in T2DM + kidney disease (UACR >200mg/g) if eGFR is greater than 20
-Use GLP1RA if SGLT2I not tolerated or contraindicated

Answer 35

-ACEis and ARBs at MAX (esp for patients with UACR > or = 300mg/g)

Question 36

How to treat patients 20-39 YO + No ASCVD

Answer 36

No statin - moderate statin based on risk (monitor annually)

Question 37

How to treat patients 45-75 YO + No ASCVD

Answer 37

Moderate statin (monitor annually)
