Good Progress

I had appointments with my gastroenterologist and nephrologist on Wednesday.  I call it my day with the gists.  I really like both of these physicians and they're about as different as possible on the surface.  But what they do share is a deep knowledge of their medical science with equal portions of compassion, a bias for action and a willingness to educate me...which are very important to me.

Dr. Levin, my gastroenterologist, is about 70 and a focused scientist who seems to have a gruff exterior but has a heart of gold and a mind that can quickly organize data.  He reminds me of that grumpy uncle who is somewhat intimidating when you first encounter him but is quietly caring and figures out all the brain teasers.  When I was continuing to have issues with my fluid retention in the hospital and felt like the transplant physician, Dr. Levin and my nephrologist couldn't develop an approach, I asked Dr. Levin to step in and get things moving and he did.  He was also the one to diagnose me.  For that, I will be forever grateful.  During my first appointment with him, he asked if I was related to a physician named David Koontz.  I told him David is my brother in law and Dr. Levin mentioned that he trained David when David was a resident at Riverside Hospital about 25 years ago.  It shows me he's a man who cares enough about people to commit them to memory.

Dr. Parikh, my nephrologist, is probably in his early to mid 30s and is very eager and engaging.  I wrote about my first encounter with Dr. Parikh in this post.  He answers all of my questions and provides context and the reasons why lab values may be changing.  When I notice a change and express concern, he doesn't just tell me "that's normal, don't worry about it"  he tells me why its normal, what is driving the change and why I don't need to worry about it.  So often when questioning any technical expert, I'm reminded of the quote by Einstein that says "If you can't explain it simply enough, you don't understand it."  Dr. Parikh always explains things simply enough so I can understand them.   When we were talking about changing some medication levels over the summer and I wasn't ready to change them as much as he was, he listened to my concerns and said we would try my course of action first.  To me, that shows a great deal of confidence in his ability to manage my condition since he didn't insist on his course as the only course.

On Wednesday, Dr. Levin told me that he could feel that my liver size has reduced.  I felt that but his assessment validated that it wasn't just wishful thinking on my part.  He also said my liver is no longer rock hard.  Liver hardness < Rock  That's a nice equation.  I was reading the proceedings of the International Symposium on Amyloidosis and read this interesting information in the history section.

Thomas Bartholin, discoverer of the lymphatic system in humans, described in his Historiarum Anatomicarum Rariorum the autopsy of a female whose spleen was so hard that it could scarcely be cut with a knife.  He stated that incision of the spleen produced a sound like that of the cutting of spongy timbers. This autopsy report was included among the 3000 collected in Theophili Boneti’s Sepulchretum Sive Anatomia Practica which was published in 1679.

That type of organ hardness is what I've imagined my liver is like.  Nice to know Dr. Levin feels that its softening up.  Goodbye spongy timbers!  (When I read "spongy timbers" I thought that would be a good name for a pirate ship captained by Spongebob Squarepants.)

Dr. Parikh said that my kidney function is normal except for an excessive amount of protein in my urine.  The amyloids have pried open the filters in my kidneys.  Substances that are too large to pass from the blood into the urine through the normal size filter will go through in an amyloid damaged kidney.  Protein that should stay in my blood leaks into my urine through the filters that have been pried open.  He said that's improved thus far and he expects it to continue improving.

In Amyloidosis, they measure treatment response in hematologic response (are you no longer producing the substances that create the amyloids) and organ response (are the organs damaged by the amyloids recovering.)  My doctor said that organ response can take up to three years to complete and in the studies I read, that seems to be the standard period of time they look for changes.

I had a complete hematologic response and as long as my immunoglobulin free light chains are normal, that response is continuing.  There are defined standards to determine organ response.

For the liver, that criteria is ≥50% decrease in an initially elevated alkaline phosphatase level, or decrease in liver size by at least 2 cm.  My alk phos level has reduced by 33% in 9 months and I still have 27 months within which improvement could occur.  I go next week for an ultrasound to measure my liver.  Last time they measured it, it was 24cm.  22cm next week shows organ response in the liver.  Now, bear in mind that normal for someone my height is about 8cm. It reminds me of that scene in the Grinch where his heart grew 3 sizes that day...except for me its my liver and it wasn't undersized to begin with, as far as I know.  But I sure got the 3 sizes thing.

For the kidneys, response criteria is 50% reduction in 24-hour urine protein excretion (at least 0.5 g/day) without worsening of creatinine or creatinine clearance by 25% over baseline.  At my appointment in December, my 24-hour protein had reduced by 48%.  So close but I'm going to round up.  I'm sure I'll be officially in the response criteria when they measure it again, probably in April.

So, more good news and good progress.  The bad thing about doing so well is that I'm now on 6 month follow-up with Dr. Levin and Dr. Parikh.  I'm really going to miss seeing them but since it means that I'm getting better, then sorry guys, we're going to have to get comfortable with a long distance relationship (time-wise, at least.)  It sure beats the alternative of being in a health state where they are managing an active disease process.

So, docs, see you in July.  Hope you don't miss me too much!
