Hi! Welcome to our video
series on glomerulonephritis.
00:05
In this video,
we're going to focus
on acute post streptococcal
glomerulonephritis.
00:11
Now, I know that's a mouthful
but we're talking
about what happens
after a patient has a
streptococcal infection.
00:18
So remember that
glomerulonephritis
is an inflammation
of the glomeruli
and it affects both kidneys.
00:24
Now those glomeruli are one of
three important parts of a nephron,
the working unit of the kidneys
you got about a million in
each one of your kidneys.
00:34
So we're all walking around
with about 2 million nephrons
and a glomerulus is one
of three important parts
of that nephron.
00:42
It's where all those little
capillaries are located.
00:45
So it's a really important
part of filtering.
00:48
Now glomerulonephritis
is an inflammation
of those glomeruli.
00:53
It can be acute
happen really fast
or chronic over
a period of time.
00:58
Now it is one of
the major causes
of end stage renal disease.
01:03
Yeah, end of the line.
01:05
End-stage renal disease
is renal failure.
01:09
Without your kidneys,
your body just becomes a mess.
01:14
So you've got it in mind.
01:15
We're talking about
glomerulonephritis.
01:17
It's an inflammation
in the glomerulus.
01:20
In this video,
we're focusing on after a
streptococcal infection.
01:26
So we've got some other causes
infection is one of the main one
and this is where we're
going to talk about
what happens after an infection
with the bacteria streptococcus.
01:35
There's also autoimmune
diseases, vasculitis,
conditions that
scar the glomeruli
like diabetes or hypertension
and those weird ones we added in,
amyloidosis or illegal drug use.
01:47
But let's go back
to the very top.
01:49
We want to talk about
a rather common case
of glomerulonephritis
that happens after infections.
01:56
a post streptococcal infection.
01:58
So we've established
that this type of
glomerulonephritis
is caused by a
streptococcal infection.
02:05
So acute means it happens
within a short period of time
post streptococcal,
post meeting after
and infection with streptococcal
is an inflammation
in the glomeruli.
02:17
Now that is a lot of words,
but if you can break words
down in medical terminology,
it will help you
remember the side effects
and symptoms to look for.
02:27
So we know why the
glomeruli are struggling
because it's about one to
two weeks after an infection.
02:33
So it's most common in
children and young adults.
02:36
Why do you think that is?
Well, it's most common in
children and young adults
because it's most common
for this group of patients
to develop a strep infection.
02:46
I'm sure you've seen someone
or maybe you've even
had strep throat.
02:51
And if you've ever seen
a kid with impetigo,
you will not forget it.
02:55
So since this is common in
children and young adults
those of you that are
interested in pediatrics,
you should be really aware
of this possible problem.
03:04
It develops about one to two
weeks after the infection.
03:07
Somebody's had a streptococcal
infection in their tonsils
on the pharynx or their skin.
03:14
So pediatric nurses,
what do we want you to
be on the lookout for?
Right.
03:19
Patients that have a
streptococcalinfection
about one to two
weeks afterwards
might develop a
glomerulonephritis.
03:26
Whoa, do you see that picture?
Doesn't it make you
want to just scoop
that little toddler
up kiss them?
Yeah, no, impetigo looks worse
than it really is but
it is not attractive.
03:39
It's really difficult doing
this with little kids,
So they don't spread
it other places,
but we'll treat this
with antibiotics.
03:45
But what we're
focusing on here is
we want to make sure that you have
educated your patients to know
Hey if there's any change
in their urine output
or any challenges
that you notice,
please let us know
about 1 to 2 weeks
after they have the infection.
04:00
Strep throat.
04:02
Now, this one can be brutal.
04:03
It's important that all of us
recognize the signs and symptoms
of streptococcus in your
throat or strep throat
because this happens very
often in the community.
04:13
So you have a swollen uvula
which that word is just fun to
say, isn't it?
Uvula, I like it.
04:20
They have Petechiae, those little
red spots on the roof of their mouth.
04:24
They have inflamed tonsils
and that You have some
big white spots on them,
but probably have some
grey spots on their tongue
and they will have an
excruciating sore throat.
04:34
So we've talked about
two examples of strep,
impetigo, which usually happens
mostly in the little tiny guys
and strep throat,
which we see a lot in
kids and teenagers.
04:45
Now I got a question for you.
04:47
What is an antibody?
Antibodies are actually
a blood protein.
04:55
Now this Blood
protein gets produced
when there's an antigen
introduced to your body.
05:00
This is a good thing.
05:01
This is how our
immune system works.
05:03
So an antigen is
introduced to my body
my immune system responds
by making these antibodies
and now I've got this
specific blood protein
that's traveling around these
antibodies to help recognize
and fight off this antigen.
05:18
It becomes a bit of a problem
with glomerulonephritis.
05:21
In fact, that's how strep
causes glomerulonephritis.
05:26
These antibodies to strep,
strep was the antigen.
05:29
So the antibodies to the
strep antigen develop
and they deposit
in the glomerulus.
05:34
That's what causes
the inflammation.
05:36
Now the glomerulus
is one of three parts of the
Nephron, right?
The glomerulus and you got the
PCT in the DCT those tubules.
05:45
The glomerulus, is that really
fragile group of capillaries.
05:49
So if we have this really fragile
group tangle of capillaries
that now is all plugged
up with these antibodies.
05:57
That's why you have
inflammation there
and it's not as effective.
06:01
The kidneys are not going
to be able to function
as effectively as they did
before they got all clogged up
with the antibodies from
the strep infection.
