We Don’t Know We Don’t Know

(This blog also appears on the Bowel Research UK website)

Do you have a “quotation that inspires you”? The one I would choose is probably not an obvious one for a health blog. You might have been expecting me to have trawled through the “inspirational” websites to find some relevant, life affirming words. I hope you’re not disappointed….

Here goes. Over to that well known, recently passed, US philosopher, Donald Rumsfeld. It’s the quote he was ridiculed for at the time, unfairly in my opinion, as it makes perfect sense. In case you don’t remember what he said :

“…as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns- the ones we don’t know we don’t know.”

Bear with me, I hope it will become clear. To illustrate the point I’m using a subject I feel particularly strongly about – bile acid malabsorption (BAM). As someone very actively engaged in bowel issues, I’ve read many comments from patients who have recently been diagnosed with BAM and many times they go on to say that their doctor had never heard of the condition before. That’s the first hurdle to overcome.

If you have been diagnosed with BAM you’ll know that it causes chronic diarrhoea. Bile acid is usually recirculated to the gallbladder via the far end of the small intestine. If that area is damaged or compromised the bile acid passes directly into the colon triggering the secretion of extra water, leading to looser stools. It can be a very debilitating condition.

I am a fellow sufferer as a result of losing my terminal ileum. (I had an ileostomy back in October 2010. Full story in my free to download book!). Before the operation I was offered the chance to take part in an Enhanced Recovery Scheme at one of the top London hospitals. Part of the ethos behind this regime is to fully inform the patient of what will happen at all stages of the process – pre-op, during the hospital stay and beyond. Was I told about BAM before the operation? I’d have to answer “maybe” and this brings us to the point of this post. Let me explain….

I was expecting my digestive system to function normally after the surgery. The Enhanced Recovery Nurse and the surgeon had told me that absorption of vitamins and salts would be much reduced as I would no longer have a terminal ileum. If someone told you that your body wouldn’t absorb salts properly what would you take that to mean? I took it at face value, I would need to up my intake of salt (sodium chloride) to compensate and take supplemental vitamins. I didn’t see the need to question the statement as it seemed very clear. Maybe I should have been more curious as I left hospital with a long term prescription for 12 Imodium capsules per day.

In fact it took four years before I underwent a SeHCAT scan and was diagnosed with severe BAM. It was then that I discovered it has an alternative name “Bile SALT Malabsorption”. Suddenly the comment about not absorbing “salt” took on another meaning. You can see the problem.

This is where Donald Rumsfeld comes in. I heard what the Enhanced Recovery Nurse and the surgeon told me; I understood what the words meant to me; but didn’t appreciate what the words meant to them. From their point of view – they were using their everyday, medical terms to describe a likely problem to a patient.

From this experience I have learnt to always question what I am being told and to do my best to get the doctor, consultant or surgeon to explain, in simple or non-medical terms, exactly what they mean and what they perceive the implications to be.

I keep coming back to those particular words from the quote “there are things we don’t know we don’t know.” Try repeating them to yourself as you enter the consulting room, either side of the desk.

Bear with me, it will become clear. To illustrate the point I’m using one of my favourite subjects – bile acid malabsorption (BAM). Maybe “favourite” isn’t the right description, make that “a subject I have felt the need to write about several times before”. There’s barely a day goes by when I don’t see a comment, on one of the IBD or BAM forums, from someone who has just been diagnosed with BAM and many times the post goes on to say that their doctor had never heard of the condition before. That’s the first hurdle to overcome.

5th September 2016 – Gastro Appointment – Guy’s Hospital – 10:20am

…the story so far can be found in the post “Crying Wolf”

Today’s appointment was to get the results of the MRI scan I had five weeks, or so, ago and then work out the way forward to get my health back on track.

It was the first appointment following my retirement so no chance to just leave the office for an hour to attend. It would need a special trip and chance to suffer the reduced timetable operated by Southern Rail. Having left home in plenty of time I arrived at Guy’s only two minutes before the due time. Almost immediately my name was called for me to be weighted. I had lost around 6 kilos since my last appointment. I asked the nurse to put a note on my records that I wanted to see my usual doctor. “No problem”.

Being weighed allows you into the inner sanctum, the inner waiting area, from where you are collected by your consultant. A student approached me and asked if I would be prepared to take part in some genetics based IBD research. I’m always more than happy to help so he left me a document to read and would talk to me after I had seen the consultant.

The waiting area was remarkably quiet. It’s been jam packed on previous visits and I’ve waited over an hour to be called. I’ve been preparing to give a talk on “Living with IBD” as part of a lecture for undergraduate nurses on chronic conditions. I had intended to do it completely off the cuff but I have come to the conclusion that is unrealistic. I’ve written out what I want to stay and the software has then converted it to speech so that I can listen to it on my iPod. This seemed like a good time to give it another listen.

I was miles away, submerged in the narrative about weight loss and fatigue in IBD, and then realised my name was being called. It was my consultant. I apologised for appearing to be on another planet and we made our way into the consulting room. By now it was 10:50am.

I had my obligatory list of questions with me :

  1. Results of colonoscopy 13th July 2016 – “ongoing mild colonic Crohn’s Disease. Previous colonoscopy” – 25th February 2015 – “mild, patchy erythema throughout the colon, however no ulceration seen”. Has there been a change? Does it need to be treated?
  1. Results of MRI scan?
  1. BAM – could this be causing weight loss etc. Treatment – Questran (low tolerance) Colesevelam.
  1. Blood test organised for 2 weeks. Have asked for cholesterol to be checked

Starting with the 1) it did suggest that the Crohn’s has returned albeit mildly. I mentioned that my last calprotectin level had been elevated – around 425. He called up all my results and drew a graph which showed that the last result did not follow the trend. “Collect a sample pot on your way out and we’ll re-run the test in case that was a rogue value. Let me know when you drop the sample in so that I can keep an eye out for the result.”

I asked about potential drugs to treat the inflammation. (Usually I would have been kept on a maintenance dose of Azathioprine but the onset of thrombocytopenia back in 2008 had made this a non-starter). He explained that there were drugs that specifically targetted the colon that were used to treat ulcerative colitis. He mentioned a form of Budesonide. I have subsequently looked this up and found a NICE document about Budesonide multi-matrix (MMX/Cortiment). It is formulated to release at a controlled rate throughout the colon to minimise systemic absorption. The licensed dose is 9 mg in the morning, for up to 8 weeks. It was licensed in October 2014 for inducing remission in mild to moderate active ulcerative colitis in adults for whom aminosalicylate treatment is not sufficient.

2) What did the MRI scan show? Strictures in my colon but they hadn’t shown up on the colonoscopy. Usually a colonoscopy trumps an MRI scan so this was an unexpected result. He proposed to take the results of both to the next MDM (multi-disciplinary meeting) to try and come up with an explanation.

It also showed adhesions but the fact they existed was not news. Since shortly after my reversal I had been complaining of an ache around the anastomosis .

3) Given the very variable nature of my digestive system and my recent weight loss I wondered if it was finally time to bite the bullet and start taking a sequestrant to treat my severe bile acid malabsorption. I had been fighting shy of taking yet more drugs and have been controlling it Loperamide.

I asked if it would be possible to prescribe Colesevelam (the tablet form) rather than Questran (powders) as I had read many reports of the former being easier to tolerate. I was aware of the cost differential, a factor of 10. He said that for the good of the health service budget I should try the Questran first but this would be a discussion for me and my GP.

4) I mentioned that I had a blood test organised for a couple of weeks time and would send the results through to him. I had asked for a cholestrol check to be carried out.

He would organise my next appointment once the MDM had discussed my results. He then took me back to the student doing the genetic study and I spent 10 minutes answering questions and spitting (saliva into a sample tube).

Where did that get me?

I’ve learnt about the possibility of a new drug to treat the inflammation in my colon and I’ve set in motion potentially directly treating the BAM. I think I’ll leave the decision on that one until my next appointment when we have an answer on colonoscopy/MRI scan conflict.

…and in the meantime an old client has called me up to see if I would be free to do some work for them. Retirement will have lasted precisely 5 weeks…
