The Story of Glomerular Injury 1-7
Glomerular Injury 1
It has been long since June met Professor
Joatmon in his limestone
cave of holistic medicine
full of stalactites and stalagmites. At present if you move these curtains you
can spot June looking smart in that suit, standing on the pulpit with a laser
pointer in her hand. From a lecturer she has quickly become an Assistant
professor now, teaching in the Macchapucchare
College of medical sciences, Nepal .
She’s at the moment presenting a paper on preventing and managing glomerular
diseases in the community. You can stay on if you’d like to view her
presentation.
June starts off with, “May we have the
first slide please?”
The first slide is a picture of
Macchapucchare teaching hospital, Pokhara ,
Nepal where I
live and work. To talk on renal diseases their impact and strategy for long-term
solutions I am going to begin by relating a story, which has been synthesized
from the stories of a number of our patients and doesn’t necessarily reflect
any real life patient. Prem Bahadur Khadka (not his real name) is a 25 year old
boy who hails from a remote village near Jumla ,
Nepal and had
never seen a bus or car in his life before he left his village for higher
studies.
This is his village where the only means of
travel was an airstrip apart from the other option of a few days of walking.
Prem was intelligent and soon after he
finished his 10th grade exams he decided to leave his village for
higher studies.
Glomerular Injury 2
He came to Pokhara, enrolled in a good school
and saw proper roads and vehicles for the first time.
As he was a good student he got into
engineering and after finishing his degree, arrived in US as a software
analyst. However he felt miserable there as he kept missing his relations and his
mother’s cooking (among other things). He was actually relieved when he got the
pink slip and lost his job after the economic slowdown.
He came back to his village (and his
mothers cooking) but found that by now he couldn’t adjust with his brothers who
knew more than him about farming and all his knowledge of software was of no
use in the village (which didn’t even have a single computer).
Glomerular injury 3
While all this was happening to Prem our
protagonist in his macrocosm, quite unknown to him or anybody else a major war
had already started inside his kidney where his glomeruli were being attacked
by a lot of inflammatory cells.
This is a cartoon borrowed from Harrison ’s principles of Internal Medicine, which shows
in molecular detail the happenings inside a cell in Prem Bahadur’s glomerulus.
You can see how the antigens are processed and finally parceled into an
endosomal compartment containing the MHC class II molecule .The antigen settles
down into the groove of the MHC and sets off a chain reaction stimulating a
clonal proliferation of hordes of inflammatory T cells.
Glomerular injury 4
This is the strong inflammatory response
inside Prem Bahadur’s glomerulus
as a result of which we expect to
see a lot of protein and RBCs in his urine (if only we could have examined it
earlier). However Prem Bahadur didn’t notice anything wrong with his urine. His
neighbors noticed him growing plump day by day and complimented him on this
sign of prosperity. At first Prem Bahadur was also happy that he was getting
fat but later noticed that he was unable to enjoy his mother’s cooking due to a
feeling of extreme nausea. This too was ignored by him until one day he
developed extreme breathlessness and had to be rushed to our hospital in
Pokhara.
This is a picture of our hospital on a
stormy night. When I saw him in our casualty (for the first time) I found him
gasping for breath, his lungs were full of crepitations which we quickly
treated with Lasix and referred him to Katmandu
for dialysis. At Katmandu
they dialyzed him for fluid overload and a urine analysis subsequently showed
3+ proteins and plenty of RBCs suggesting acute glomerular injury. He was
immediately treated with high dose steroids and a renal biopsy was done.
The biopsy showed focal areas of glomeruli
that were sclerosed in segments.
Glomerular injury 5
The fire was too severe to be quenched with
steroids and it was already too late to prevent Prem Bahadur’s kidney from
blowing up in smoke.
He received a few more dialysis from Kathmandu and spent whatever money he had earned over the
past few months. His brothers came forward to donate their kidneys for
transplantation but that would mean selling off their land and cattle to go to
one of the hospitals in India and Prem Bahadur wasn’t keen on that. The next
slide is a Haiku sequence, which was mailed to me by a friend right after 9/11.
Glomerular injury 6
The last I heard of him was through one of
our medical students also from the same village. Prem was spending his last
days in deathbed with his family praying for him daily and it would be a matter
of days or months before death would take him.
This is a summary of the story of
glomerular injury taken from Harrison’s principles of Internal Medicine which
describes how it’s initiated by breakdown of tolerance leading to reactivity of
antibodies with planted glomerular antigens which in turn generates a chemical
cytokine mediated response leading to proliferation of inflammatory cells and
subsequent irreversible renal damage (in a substantial number of people).
Glomerular injury 7
The key word here is tolerance and (next
slide).
Tolerance is fast becoming popular in
transplantation research but we need tolerance urgently before the need for
transplantation arises to save our native kidneys (before the inflammatory
cells attack them). As much as we need tolerance to save this Earth before a
full-fledged war breaks out. That is the problem of glomerular injury for we
don’t really know why this breakdown of tolerance occurs. We don’t even know
why hypertension or diabetes occur (for that matter). Our present strategy is
only to control them in the hope of slowing the progression of renal disease.
