Q

Note, this has all the ACE’s/Arbs listed, so for the most important/common ones that Dr. Meaney pointed out) there’ll be cards but for the rest its basic drug info to keep the list shorter

Q

How is CKD Staged/Classified?

A

(CGA–> Cause, GFR, and Albuminuria)
1.)By CKD-Epi eGFR (NOT CrCl!) and level of Albuminuria
-For eGFR: it’s CKD-EPI, not MDRD
-For eGFR: G1-5 (G5 being ESRD/renal failure, and g3 having a and b categories)
For Albuminuria: A A1,A2, and A3 (worst) for albuminuria level
ie G2A1 or G3bA3

Q

What are the cutoffs of CKD stages?

A 
For eGFR (ml/min/1.73m^2): 
Stage G1: GFR>=90ml/min/1.73M2
G2: GFR 60-89
G3a: 45-59
G3b: 30-44 
G4: 15-29
G5<15
For Albuminuria: A1 is < 30mg albumin/g creatine
A2 is 30-300mg/g 
A3 is over 300mg/g

Q

is CKD a silent disease? If so when is it normally caught?

A

Up to 3a is normally a silent disease, in part due to the intact nephron hypothesis

Q

Can CKD be stopped/treated?

A

No, the progression can only be slowed!

Often a stepwise progression (large/small injury without a full recovery and this process repeats)

Q

Role of blood glucose control (for diabetics I;m gussing?)

A

Best to have strict A1C goals< 7%

-Can be less strict as kidney gets near or during ESRD (stages 4 or 5) because the damage is already done

Q

HTN treatment/BP Control in CKD

A

1st. ) Ace/ARB
2nd. ) Thiazide diuretic
- - Loop diuretic if they have clinically evident edema
3rd. ) CCB’s:
- -Non DHP (diltiazem preferred) for albuminuria lowering and DHP for bp lowering

Q

When to use CCB’s for HTN in CKD
(NOTE- DHP CCB’s aren’t 2nd line, just general info here, and Non-DHPs can be 2nd line (or additions) but for their albumin control, not 2nd line for BP)

A

Use Diltiazem (or verapamil if no other option) IF:
1.) Patient is ACE/ARB intolerant OR
2.) Patient is on MAX TOLERATED DOSE of ACE/ARB and still has albuminuria
-BUT can’t use these with Beta-Blockers and they have many DDI’s, so if you can’t use one then
DHP CCB: NOT 2nd line
1.) For improved BP control only BUT ACE/ARB + DHP CCB > ACE/ARB alone for renal function so it still helps

Q

Statin use in CKD?

A

Generally same dosing, they do have some benefits in NON-Dialysis patients

  • So add a statin for non-dialysis patients, if they’re already on one its okay to keep them on it once they get on dialysis too.
  • Still use it during ACS events in dialysis patients

34
Q

Dual Raas inhibition?

A

Is a no no!

35
Q

What’s Aliskerin/Tekturna?

A

It’s a DRI/Direct renin inhibitor that’s dosed at 150-300mg QD
-Same effect on CKD progression as an ace/arb

36
Q

What are the ABSOLUTE Contraindications to RAAS drugs?:

A
  1. ) Pregnancy
  2. ) Bi-BILATERAL…BIIIIIIIIILATERAL Renal artery stenosis
  3. ) History of ACE/ARB angioedema (if with ace can try an arb under supervision but if react to an ARB then can’t get an ACE or ARB)
37
Q

What circumstances should you use RAAS drugs with caution but aren’t total Contraindications?

A
  1. UNI-UNIlateral renal artery stenosis
  2. Hyperkalemia
  3. Dehydration/hypovolemia
  4. hypotension
  5. Kidney Dysfunction (SCr>3.0, eGFR<30)
38
Q

RAAS Drug monitoring and adjustment:
Labs, vitals, symptoms,
THIS SLIDE INCLUDES ACE/ARB AE’s

A

Labs: K+ and SCr within 1-2 weeks
BP and HR qd if possible
AE’s/Symptoms to watch for: Orthostasis, Angioedema, Cough (more with ACE’s, females, and African Americans)

39
Q

What to do with SCr changes:

A

Expect a decline in GFR and increasein K+
(note if only for HTN it’s a 35% decrease cutoff for stopping the drug- no middle ground in that situation)
If GFR decreases by <30%, no change is needed
If GFR decreases by 30-50%, cut the dose in half
If GFR decreases by over 50%, that’s AKI-Stop the drug and restart when Kidney funtion is stable at a lower dose

40
Q

What to do with K+ changes?

A

If K>5 recommend dietary changes
K>6 give a loop + SPS
If K>6,5, hold the drug and adress hyperkalemia then resume the drug with a better regimen

41
Q

DDI;s in CKD

A

Avoid with:
-NSAIDS–> AKI more likely (HEMODYNAMIC)
-Potassium supplements –> hyperkalemia
-Dual RAAS inhib –> AKI and hyperkalemia
Use with Caution:
-Aldosterone antags/K+sparing diuretics–> Hyperkalemia
-Lithium–> higher lithium concentrations
-Quinalipril has magnesium–> Avoid with fluoroquinolones and tetracyclines

42
Q

pears of RAAS inhibitors

A

Start low and go slow if worried about hyperkalemia- could start at 1/2 dose or 1/2 the dose of their diuretic for a little bit

  • Could tell patients to increase salt intake just for a few weeks
  • Use in all patients with CKD regardless of BP if have albuminuria and unless contraindicated
  • No CI for renal dysfunction
  • Mortality benefit in HFrEF
43
Q

SGLT2 inhibitors?

A

Have benefit in CKD progression for even NON-Diabetic patients!
Affgerent arteriole vasoconstriction decreases glomerular pressure
-Weak diuretic effect

44
Q

Possible side effects with SGLT2 inhibs in (* in CKD)

A

AKI*
Euglycemic DKA
UTI’s/genital mycotic infections
Lower Limb Amputations

45
Q

What if a patient has gout? What’s the uric acid goal and drug dosing?

A

Want uric acid<7mg/dl –> can use allopurinol or febuxostat
Allopurinol dosing: 1.5 x eGFR
—AE’s include rash/fever/ SJS and other hypersensitivity reactions- get help ASAP if start having these
— Screen (genotyping test) Asians for a particular HLA that predispposes them to this reaction

46
Q

What acid base disorder is common in ckd patients and how to treat it?

A

Chronic metabolic acidosis is common–> Treat when Serum bicarb gets below 20 using 1950-2600mg oral alkali/day (Split BID so, 975mg-1300mg BID)

47
Q

What are the lifestyle modifications recommended for CKD?

A

As CKD worsens limit protein to (at CKD3-4) <0.8g/kg/day
Limit salt to <2g sodium or <5g table salt per day
Limit alcohol to 1 (female) to 2 (male) drinks/day
Try to STOP SMOKING!
Lastly: Weight loss strategies including exercise to a goal BMI of <25kg/m^2

48
Q

Sick day management! What do you do?

A

Stop your RAAS drugs, metformin, DIURETICS, DIGOXIN, lithium, and AVOID NSAIDS

49
Q

Should we ever recommend herbals?

A

Oh yes, herbals are totally great

aka always recommend AGAINST using them, even if they’re doctor may have recommended something
