9. Why is Hospital Acquired AKI a problem
for the bedside clinician?
• Renal Physiology is Complex
• Markers of Renal Injury are not clinically used(or useful?)
• Fluid management in Sepsis is Difficult and overzealous
administration is bad
• The role of the endothelial glycocalyx in fluid distribution is
important and its integrity is difficult to measure
• Fluid Types may impact on Renal Outcome
• Therapies for AKI with RIFLE Risk and Injury are limited
• High Intensity RRT has not proven benefit
• Optimising Filter life is problematic
• In patients who have RRT in ICU the outcomes is poor

10. Problematic physiology
1. The kidney is at risk of
hyperoxia
2. The kidney is at risk of
hypoxia

11. • The kidney has a high exposure to O2
• Oxygen tension is tightly regulated in all organs
because high PO2 is toxic
• In the kidney superoxide production is tightly
dependent on O2 availability

12. • The human kidney has structural antioxidant
defences.
• Arteries and veins are closely associated
• This facilitates counter-current diffusion and
enables a high degree of AV shunting

13. Renal veins have a unique peri-arterial structure
It facilitates diffusive O2 shunting

14. Close coupling of veins and arteries to achieve counter-current O2 diffusion

15. This shunting is dependent on Renal Blood Flow

16. The cortex and the medulla
Are linked by shunting
If the cortex is underperfused
More AV shunting occurs in
interlobular vessels
This can lead to medullary ischemia
Even if medullary flow is preserved

17. Medullary PO2 is very low

19. The septic kidney: global renal blood flow

20. Intra-renal blood flow
In septic sheep

21. Intra-renal oxygenation
Cortico-medullary dissociation
Knowing global
Or even intra-renal blood flow says
little about medullary oxygenation

23. Clinical implications
• Global renal blood flow may be dissociated from
GFR, medullary flow and medullary O2
• Reliable ways to measure renal blood flow are not
available
• If there were reliable therapies to increase renal
blood flow the effect of this on GFR is unpredictable.
• The renal medulla is always at risk of hypoxia

24. Biomarkers for the prediction of acute kidney injury: a narrative review on
current status and future challenges
Hilde R. H. de Geus, Michiel G. Betjes and Jan Bakker Clin Kidney J (2012) 5
(2): 102-108
Biomarkers for AKI
• Functional markers- SCr and plasma/serum CyC
• Up-regulated proteins -NGAL, KIM-1, L-FABP and IL-18
• Low-molecular weight proteins -Urine CyC
• Enzymes NAG,- a-GST, p-GST, GGT and AP
Markers of Renal Injury are not clinically
used(or useful?)

25. The reported AUCs are disappointing ranging from 0.50 to 0.84, with one
or two exceptions, which can be explained by statistical or
methodological differences in study design.
The discriminatory function in heterogeneous populations is poor and
influenced by pre-existing renal function and time of sample
collection with respect to the renal insult
Clinical appraisal of a patient using standard parameters such as
SCr and diuresis remains the cornerstone for now
Reasonable to use biomarkers together with other parameters such as
traditional clinical characteristics to optimize the accuracy of prediction of
developing AKI

29. Design
• VASST Study Patients: The Vasopressin in Septic
Shock Trial (VASST) study enrolled 778 patients who
had septic shock
• A retrospective review of the use of intravenous
fluids during the first 4 days of care.

30. • Based on net fluid balance, they determined
whether fluid balance quartile correlated with
28-day mortality

34. • A more positive fluid balance both early in
resuscitation and cumulatively over 4 days is
associated with an increased risk of mortality
in septic shock

35. Next Question.
• Whether fluid balance was predictive of
central venous pressure ?
• Whether a guideline-recommended central
venous pressure of 8–12 mm Hg yielded a
mortality advantage?

36. Figure 3

not correlate with central venous pressure nor with the
dose of norepinephrine.

Figure 4.A, Cox survival curves, adjusted for age,
Acute Physiology and Chronic Health Evaluation
(APACHE) II score, and severity of shock (dose of
norepinephrine), are shown for central venous
pressure (CVP) groups at 12 hrs. Patients with
a CVP of <8 mm Hg at 12 hrs have the lowest
mortality followed by those with CVP of 8–12
mm Hg and patients with a CVP >12 mm Hg
had the highest mortality

38. • Central venous pressure correlated with fluid balance at 12 hrs.
• On days 1–4, there was no significant correlation.
• At 12 hrs, patients with a central venous pressure <8 mm Hg had
the lowest mortality rate followed by those with central venous
pressure 8–12 mm Hg. The highest mortality rate was observed
in those with central venous pressure >12 mm Hg.
• There was no correlation between CVP and mortality at day 4

39. • However, in patients whose central venous pressure was <8
mm Hg
• Found a more positive fluid balance among survivors
compared with non survivors
• Suggesting that there is a point at which too little fluid is
indeed harmful

acute renal failure.

49. Improved understanding of microvascular physiology allows explanation of the
discrepancy between clinical findings during fluid therapy and the original
Starling principle
The role of the endothelial glycocalyx in fluid distribution is important and its
integrity is difficult to measure

51. MATERIAL AND METHODS: A total of 150 individuals were tested for levels of inflammatory markers
(intercellular adhesion molecule-1 [ICAM-1], vascular cell adhesion molecule-1 [VCAM-1], interleukin-6
[IL-6]) and glycocalix markers (syndecan-1, heparan sulfate). Three groups consisted of patients with
severe sepsis or septic shock, patients after major abdominal surgery without systemic
inflammatory response syndrome, and healthy volunteers. Blood was drawn, at the time of diagnosis
or surgery, and 6, 24, and 48h later.
RESULTS: Levels of inflammatory markers were markedly higher in patients with sepsis compared with
patients after major abdominal surgery and healthy volunteers. After major abdominal surgery,
glycocalix markers in human plasma were at levels comparable to patients with sepsis. In patients
with sepsis, levels of IL-6 correlated with syndecan-1, ICAM-1, VCAM-1, and lactate, while ICAM-1
furthermore correlated with CRP and lactate levels.
CONCLUSION: High levels of glycocalix markers indicated that significant flaking of the endothelial
glycocalix occurred in patients with sepsis, and to a lesser extent in patients after major abdominal
surgery. This novel finding could explain the nonspecific capillary leaking syndrome of patients with
sepsis and after major abdominal surgery, and may identify new targets for treating those patient
populations.

Increase in median of BNP of patients with AKI on admission

55. • In this pilot study, demonstrated for the first
time an association between plasma BNP
levels and AKI in critically ill patients.
• Patients with AKI have higher levels of BNP
compared to no-AKI patients, and in AKI
patients BNP levels continue to increase during
the subsequent 48 hours.
• Results suggest that plasma BNP may
distinguish the occurrence of AKI.

69. AIM
The primary aim of the study is to assess the effects of a continuous supplementary
infusion of standard L-amino acids on renal function, renal failure and recovery from
renal injury in critically ill patients who require at least three days of intensive care.
The effects of a continuous supplementary infusion of a standard mixture of L-amino
acids will be compared to standard care with regards to the onset and severity of
clinically significant renal dysfunction, need for RRT, renal recovery rates, need for
ongoing dialysis, and health status (quality of life, physical function and overall survival) at
follow-up 90 days after randomisation.

97. Found that patients with AKI treated with RRT in the ICU were at high risk of
dying during the 3.5-year follow-up period; overall 31.9% of those surviving to 90
days died during the extended follow-up period.
The risk of dying was much greater than the risk of entering a maintenance
dialysis program, with neither outcome being influenced by the use of a higher
intensity of RRT.
The rate of albuminuria in survivors was substantial, despite relative preservation
of renal function

98. • Consider causes other than ATN.
• Be mindful of Nephrotoxic drugs.
• Restore MAP and ignore CVP after a few days in ICU
• Fluid overload is bad and fluid therapy in ICU is a
dynamic process.
• After initial resuscitation aim for a neutral or negative
fluid balance
• Synthetic colloids should be avoided
• Consider Citrate
• Follow up of survivors should be considered with
attention to strategies to decrease albuminuria
