Chronic Kidney Disease
• When would you request renal consult for
your CKD patient?
A.DM eGFR >60 ml/min , albuminuria 500 mg/g
B.DM eGFR 45 ml/min, albuminuria 50 mg/g
C.HTN eGFR 30 ml/min, albuminuria 30 mg/g
D.HTN eGFR 40 ml/min, albuminuria 2000 mg/g
Prevalence of CKD
• 7% US adults over age 20 (eGFR <60)
• 12.3% (eGFR and albuminuria)
• Age – demographic factor most most strongly
associated with CKD
• 35% of Americans over age 60 have CKD
• What is the most common cause ESRD in US
a.HTN
b.Diabetes
c. Hepatitis related
d.SLE
e.ATN
Screening
• ACP – recommend against screening for CKD if
asymptomatic and without risk factors;
• USPSTF – insufficient evidence for screeining
CKD in asymptomatic patients
• ASN – screening recommended
Relationships between cardiac events and loss of life expectancy resulting from cardiovascular disease
(CVD) by stage of chronic kidney disease (CKD).

– Goal : JNC 8 <140/90 (vs 130/80 JNC 7)
- Acei/ARB – 1st
line for most pts with HTN and CKD
• What is the recommended initial tx for black
pts with proteinuria?

• Osteomalacia
• Osteoporosis * DEXA
KDIGO guidelines for CKD MBD
• Monitor iPTH, ca, phos and vit d 25 OH
• Replace vit d to >30
• Calcitriol or calcitriol analogues if PTH remains
high despite adequate vit D
• Low phos diet
• Phos binders
Survival of treated and untreated patients,
phosphate 4.6 to 5.5 mg/dl

Anemia
• Causes of anemia among pts with CKD include
the following except
• Decreases erythropoietin production
• Erythropoietin resistance
• Reduced erythrocyte lifespan
• ACEi
Anemia
• Hb goal 10-11
• Transferrin saturation > 30%
• Ferritin > 500 ng/mL
When do we check EPO levels in CKD
• Hb 10
• Hb <8
• Hb not improved after iron replacement
• Hb not improved after 1 month of starting ESA
• Never
Black box warning for ESA
• Increased mortality and tumor progression
among pts with active malignancy
• Increased risk of thromboembolic events
• Increased CV events among pts with Hb >11 or
h/o CVA
Acidosis
HCO3

de Brito-Ashurst I et al. JASN 2009;20:2075-2084
OTC Medications to Avoid in CKD
• NSAIDs
• Decongestants (psudoephedrine;
oxymetalozine)
• Laxatives ( Mg Oxide; Na phosphate)
• Antacids ( Al OH; MgOH; sucralfate)
• Nutritional supplements (creatine; salt
substitues)
• Herbal remedies( aristolochia; ephedra)
Summary
• Identify and refer CKD pts with increased risk of progression to
nephrologist
• ACEi 1st
line agent for pts with HTN and CKD especially among those
with albuminuria
• Check ipth, phos and vit D. Correct to normal
• No utility in checking EPO for anemia work up among pts with CKD
• Treatment of acidosis delays progression of CKD
• Counsel pts on risks of certain OTC medications that should be
avoided in CKD

Editor's Notes

  • #8 Relationships between cardiac events and loss of life expectancy resulting from cardiovascular disease (CVD) by stage of chronic kidney disease (CKD). A and B, The adjusted relative rate of all-cause mortality (ACM) and acute myocardial infarction as a function of glomerular filtration rate (eGFR; mL·min−1·1.73 m−2) and severity of albuminuria as assessed by albumin-to-creatinine ratio (ACR; normal, ACR &amp;lt;30 mg/g; mild, ACR 30–300 mg/g; or heavy, ACR &amp;gt;300 mg/g). C and D, Adjusted loss of life expectancy resulting from CVD by CKD stage. Loss is compared with life expectancy in people with normal or mildly impaired kidney function (stage 1–2, eGFR ≥60 mL·min−1·1.73 m−2) and normal or mildly increased albuminuria (stage 1, ACR&amp;lt; 30 mg/g). RRT indicates renal replacement therapy. C and D are reproduced from The Lancet, Gansevoort et al7 with permission from the publisher. Copyright © 2013, Elsevier.
  • #18 (A through E) Survival of treated and untreated patients in the overall propensity score–matched cohort (A) and according to quartiles of baseline serum phosphate: &amp;lt;3.7 mg/dl (B), 3.7 to 4.5 mg/dl (C), 4.6 to 5.5 mg/dl (D), and ≥5.6 mg/dl (E). We performed intention-to-treat analyses to compare patients who began treatment with phosphorus binders during the first 90 d after initiating hemodialysis (n = 3555) with those who remained untreated during that period (n = 5055). Propensity scores try to identify factors that predict whether treatment given or not, and allow matching for “probability” of receiving treatment. i.e. treatment and control groups that would have the same likelihood of being treated.
