00:01
Okay.
00:02
So let's now talk
about risk factors
that can progress our patients.
00:06
Now this is important,
we've diagnosed our patient,
they have chronic
kidney disease,
They're sitting here before us,
we need to know what can we do
to mitigate some of those factors
that are going to put them at
an increased risk of progressing
and potentially moving towards
end-stage renal disease.
00:22
Things that we need to
really pay attention to
are things like proteinuria.
00:26
Do they have in particular
greater than 1 gram
of protein per day.
00:30
That's a very very high risk
that that patient is
going to progress.
00:34
Is that patient hypertensive
despite the fact
that we're trying to
control their blood pressure
that actually puts
them at an increase
in risk of developing
chronic kidney disease
that's Progressive.
00:45
The type of underlying
disease is also important
if I have a diabetic
they almost always progress.
00:51
Despite the fact that we try our
best efforts to control them.
00:54
That's a highly
Progressive disease
and polycystic kidney disease.
00:58
Remember we talked about
Autosomal dominant
polycystic kidney disease.
01:01
That's a genetic
disease for which
at this point in
time we have no cure
those are so those patients
are certainto progress.
01:08
African-American race
is also important
we talked about that
APOL1 Allelic variant
that puts people at risk of
developing Progressive disease
so it's something that
we have to keep in mind.
01:17
And believe it or not gender
has a role in this as well.
01:20
Men progress more than women.
01:23
So we need to think
about that as well.
01:25
And then obesity.
01:26
So typically people
over with a BMI greater than 30
have an increase in
glomerular capillary pressure
and that also puts that patient
at risk for progression.
01:38
Having lipid
abnormalities dyslipidemia
is also a risk factor
for progression.
01:43
Smoking, I think that's a
no-brainer for most of us.
01:45
We know patients
should quit smoking
but patients who
continue to smoke
will have progression.
01:51
And high phosphorus levels.
01:52
We just went over
bone mineral disease
having high phosphorus
that's not controlled
is certain to
progress our patients
as well as developing
metabolic acidosis,
and it's interesting because
as we supplement those patients
with sodium bicarb,
we actually see that
appears to slow progression
probably because
of a reduction in
tubulointerstitial
inflammation from the bicarb.
02:15
So a couple of other risk factors
that we need to think about
are having a high protein diet.
02:19
So what's important to think about
when it comes to high protein diets,
I'm not talking
about normal patients
who don't have chronic
kidney disease.
02:26
These are patients who have
underlying chronic
kidney disease.
02:30
And it's that high protein
actually can increase GFR
it causes vasodilation
and then hyperfiltration and when
you have that hyperfiltration
you increase your glomerular
capillary pressure
causing glomerular
capillary hypertension
and because of they don't have
appropriate autoregulation
that can lead to progressive
glomerulus sclerosis,
so that's how high
protein diets in patients
who have underlying
chronic kidney disease
can progress their disease.
02:55
Again, I want to just really
illustrate a point here that
if you have a patient in the
absence of chronic kidney disease,
we don't have data
at this point in time
that high protein diets
are going to accelerate
or cause chronic kidney
disease in that population.
03:08
And then finally hyperuricemia,
so there's data emerging
that lowering your egg
acid levels may have
slowed the rate of GFR loss.
03:15
But I also want to illustrate
another point here.
03:18
The jury is still out.
03:19
We have some randomized
controlled trials
that are ongoing right now
that are really going to
definitively answer that question.
03:23
So stay tuned.
