When a car is assembled, the parts
are not made on location, but they come from various suppliers around the
world. The seats from one factory, the
engine from another, the tires and wheels from another, etc. These parts are delivered on a schedule so in
a month if 1,000 cars will be assembled there is a delivery of 1,000 radios.
The body’s immune system
functions in a similar way. Plasma cells
in the bone marrow are the factories where proteins chains are made. These chains are assembled outside the plasma
cell and create the needed immune systems to fight infections. On occasion, using the car factory analogy,
some of the factories goes crazy and kicks out a large order of proteins that are
not radios, but refrigerators. This is a
very simple explanation of what occurs with AL Amyloidosis. Over eager plasma cells generate a large
number of proteins that are ill-shaped and made wrong. These proteins will float around in the body
and not assembly with other proteins. The
overabundance the wrong or ill-shaped proteins will cause damage to certain
organs in the body. One protein called a
Lambda Free Light Chain (λFLC) will cause damage to the heart and nervous and
digestive systems. This is what happened
when I had heart failure and why I received a heart transplant back in
September 2009. If you look at the graph
at the top of the page, there are two flat lines and a squiggly line. The area between
the flat lines is an acceptable area of production of the λFLC. The squiggly line shows the production levels
of my λFLC that have been assessed from blood draws since when I was first
diagnosed with this disease back in February 2009. When the doctors put me through chemotherapy
or a stem cell transplant, the intention is to destroy the factories that are
over producing the λFLC parts. You can
see each time I go on a heavy dose of chemo, the numbers of λFLC
drops, but never reach the proper range. The squiggly line never gets down to
where it should be. Even after going
through my last stem cell transplant with a high dose of chemo in December 2011. In fact, the λFLC numbers have gone up
slightly and have now plateaued off. Going
back to the analogy with the car factory; someone needs to bomb the factories
that are making all those refrigerators!!!
The chemo should be doing this and this is the best weapon against this
disease the doctors have. The disease is
very persistent. In medicine, there are
new weapons, better chemotherapy being developed all the time. It is a forgone conclusion that I will need
to be on some form of chemo for the rest of my life. Right now, my young bone marrow environment is
too tender to go through more abuse. I
still have a ways to go with recovery from the last transplant.
Rick. What a great job of dumbing it down for the tiny-brained like myself.
