A Day in the Life of an Irregular Blogger

Aloha! It's been another age since I've written in here! My apologies. I thought I'd pop by to give you a quick update.

Way back on the 15th April I had an MRI scan at the hospital (so long ago that I had to look up the dates in my diary at work...). I didn't get the results until the 20th May, when I had an appointment with a very nice nurse in Neurosurgery. My lovely boyfriend came with me to the hospital and saw the scan images, so I guess now he is in the enviable position of having seen exactly what's going on inside his girlfriend's head!

The scans look pretty good - it's always hard to tell just from an MRI, but the surgeons were optimistic that they managed to remove the whole tumour, and there's nothing obviously wrong in the images. The trouble is that the pituitary gland is so tiny - about the size of your little fingernail - so even with the contrast injections, at best an MRI is only an indication of what's going on in there - blood tests are very important as well. But the surgeons are very happy with me, and as far as they're concerned, I don't have to have another MRI for a year. Hurrah!

On the 27th June I went to see the endocrine nurses for a synacthen test. This test evaluates how well the pituitary is producing adrenocorticotropic hormone (ACTH). This hormone is really crucial for your body, and because there's always a risk that surgery can damage the pituitary gland, patients who have transsphenoidal surgery are put on replacement steroid medication as a matter of course. The doctors will only let you come off the medication if a synacthen test shows your pituitary gland is now able to produce ACTH on demand.

I already had one of these tests back in March and my pituitary had a fairly good response, but not quite good enough to come off the medication totally. The endocrinologists halved my dose of hydrocortisone, but I'm still taking 5mg in the morning and 5mg at midday. I'm hoping that the results of my test last week will be good enough for me to come off the steroids totally. It would be in line with what happened after my last operation, when it took about six months before I was able to come off medication. Certainly immediately after the operation I was in need of the steroids - about a month after surgery, I forgot my 4 o'clock 5mg dose, and was a complete emotional wreck all evening until I remembered I hadn't taken it at about 7pm. I took it - and half an hour later I was already feeling immensely better. More recently I have forgotten to take my hydrocortisone on time once or twice and not had any ill effects at all, which hopefully is a good sign.

I don't know yet what date I'm due back at the hospital for my next proper follow-up with endocrinology. I had thought it would be the end of June, but apparently it's actually going to be the end of July, four months after my last clinic appointment. Then I should get the results of the synacthen test, and the other blood tests they did at the same time to check my thyroid levels.

I'm Still Here!

 Aloha! Long time no blog I know, profuse apologies all round. Partially I have been lazy, partially I have been working on other projects and partially I have been enjoying my recovery!

I went back to work around the beginning of March. I did a phased return, which I really recommend - the first couple of days back I felt pretty much exhausted by lunchtime, but by the end of my first week I was almost back to normal. So I've been back for two months now (how time flies!) and doing good.

I had a series of blood tests done in March by my endocrinologists and they came back looking good. My ACTH response wasn't quite back to normal, so I'm still taking hydrocortisone (albeit at a low dose), but my endocrinologists were optimistic that hopefully I'll be able to come off it in a few months. The same thing happened after my first surgery, so fingers crossed! The rest of my pituitary hormones are all fine - my TSH and free T3 and T4 came back the lowest they have ever been.

I'm back up to my pre-surgery level of fitness now too, and hopefully going to surpass it! I dance for 3 hours a week, swim for an hour, do lots of walking, the odd run, and yesterday I bought a bicycle so now I'll start doing some cycling too. I'm only taking propranolol very occassionally - I still get the odd bout of a fast resting heartrate, particularly after eating, but it's not often. I'm off to the doctors for an ECG to check that out tomorrow, although chances are it won't show anything and they'll need to do a 24-hour heart tape.

So all in all things are looking good so far. I've had an MRI scan now but I don't get the results til the 20th May when I go to meet with the neurosurgeon. Fingers crossed!

Post surgery update

It's coming up on a week now since my pituitary surgery last Tuesday morning. This time last week, I went out to a meal with my boyfriend and parents, then headed home for some last-minute packing.

I seem to be doing pretty well so far (touch wood). Yesterday was fun, my boyfriend's parents came to visit which was really lovely, and I even made it outside in the snow very briefly. Normally, I am a keen maker of snowcreatures (my best effort to date being a snow walrus) so it has been very sad for me to not be able to take advantage of the weather.

Today is the first day I've not had an afternoon nap, though I'm mostly still alternating between lying on my bed and lying on the sofa downstairs. I think compared to last time I had surgery I feel a bit more awake mentally, but physically I'm still super pathetic. My brain is quite happy typing this all up, but my body is protesting that it would be so much easier to just lie down. Except then I get super bored.

In terms of medication, I'm taking hydrocortisone - that's standard after pituitary surgery as there's always a risk that the pituitary gland will stop producing adrenocorticotropic hormone after surgery, which could be quite serious. I have a nose spray and also (prepare for grossness) I have to rinse out my sinuses three times a day. It basically involves putting a bottle full of saline solution against one nostril and gently squeezing; the water then goes up one nostril and out the other. It is a very disconcerting sensation but it's actually really good. Last time I had pituitary surgery, no-one suggested this, but because I had endoscopic transsphenoidal surgery this time, an Ear Nose and Throat surgeon worked alongside my neurosurgeon, and he has instructed the sinus rinsing. The result is that I can breathe through my nose less than a week after surgery, which is a huge improvement on last time.

Pituitary Awareness Quiz: Day 9

Eagle-eyed readers will have noted that this is in fact Day 10, but I abjectly failed to write a question yesterday (though I did write a poem, which is nearly as good) so it's only question nine. I could have called this Day 10, Question 9, but that just seems confusing so I'm working on the basis that yesterday was just a small aberration in time and space, and the quiz will continue from here!

Pituitary Awareness Quiz

Day 9, Question 9

Q.9: Which of the below is the correct spelling of the full name of the pituitary hormone ACTH? (no cheating!)

a) adrenalcortecotropic hormone

b) adrenecorticotropic hormone

c) adrenalcorticotropic hormone

d) adrenocorticotropic hormone

The Very Scary Case of Kane Gorny

Before going into hospital last Tuesday, I stopped off at one of my favourite cafes for a hot chocolate, as a pre-hospital treat. I wasn't allowed caffeine in the three days before going in, so I had been suffering from a woeful lack of hot drinks. I got my hot chocolate (which was delicious) and sat down by the pile of daily papers they keep at the café. Alas, all the more upmarket titles had been taken, so I had to settle for that peculiar bastion of journalistic achievement: the Daily Mail.

You can imagine my feeling of ill-omen when, immediately before going into hospital overnight for further investigations into my pituitary tumour, I saw that the Mail's headline story was about Kane Gorny, a 22-year-old with a pituitary tumour who died of dehydration in hospital after nurses denied him his medication.

You can read the Mail's story online here. According to the Mail, it seems that after his entirely routine hip replacement surgery, nurses did not give Mr Gorny medication necessary for fluid retention; he became so agitated from dehydration that he called 999 in an attempt to get some water, but was sedated and left unattended overnight, despite his mother raising concerns. Even after his death, the attitude of some members of the nursing staff appears to have been appalling.

I thought I would tackle a couple of questions raised by the reporting on this terrible story, before moving on to look at it as a whole:

What was wrong with him?

 Kane Gorny suffered from a pituitary tumour; that much is certain. The exact details of Mr Gorny's condition are still somewhat sketchy and vary depending on which paper you read, but I'm going to guess that he possibly had acromegaly or Cushing's Disease, from the statement of his endocrinologist that he had a "rare tumour", and the fact that he had joint problems.

Most papers have reported that he had a "malignant" brain tumour or "brain cancer". The tumour may well have been cancerous, but it should perhaps be noted that this extremely rare for pituitary tumours; they are sometimes misreported as malignant due to journalists misunderstanding the condition and the fact that a tumour labelled "benign" may still be very harmful. In any case, I'll be looking at the definition of malignancy/cancer with regard to pituitary tumours in a future post, hopefully within the next couple of weeks, because it's an interesting question.

Why did he need a hip replacement aged just 22?

After pituitary surgery, sometimes the healthy pituitary gland is damaged, leaving it unable to produce certain hormones, including ACTH (adrenocorticotrophic hormone), which stimulates the adrenal glands to produce the steroid hormone cortisol. Without cortisol in the body, you can die quite quickly - consequently, it is standard to give patients steroid pills after surgery until doctors are certain their pituitary gland is able to produce ACTH. If the pituitary gland has been damaged, patients will need to take these pills for life.

Most reports have stated that Mr Gorny's steroid treatment left him requiring a hip replacement; high levels of steroids in the body can lead to avascular necrosis (although not in "a couple of weeks" as one paper initially reported). Additionally, if he did indeed have Cushing's or acromegaly, both of these conditions can adversely affect joints.

How did he die of dehydration so quickly?

A healthy human can live for a couple of days without water, depending on exertion and environmental conditions. Kane Gorny could not. After his pituitary surgery, Mr Gorny was left with diabetes insipidus. This is a very different condition from what we refer to as "diabetes" (diabetes mellitus) and is caused by a deficiency in anti-diuretic hormone (ADH, or vasopressin). Anti-diuretic hormone is secreted by the pituitary gland and helps to control the body's fluid balance. In diabetes insipidus, the lack of this hormone means that the body cannot conserve much of the water which it takes in, and consequently the sufferer becomes extremely thirsty and needs to urinate frequently. Unfortunately, developing this condition is a fairly common side-effect of pituitary surgery and pituitary radiotherapy.

In order to treat his diabetes insipidus, Kane Gorny would have needed to take a drug called Desmopressin (DDAVP), which is a synthetic substitute for vasopressin. As long as he was taking this drug, his body would be able to retain a normal amount of the water he drank, and he would not become dehydrated. When the drug was witheld, his body could not remain hydrated, and he died.

How could the hospital get this so wrong?

Unfortunately this is the question that can't be answered. Kane Gorny's death appears to have been preceeded by a number of absolutely catastrophic blunders at the hospital. His endocrinologists were not informed that he was in the hospital for surgery; his surgeon was entirely unaware of his condition; nurses did not read his notes; no-one listened to his mother's concerns; the list goes on.

Diabetes insipidus is a common problem among pituitary patients, but far more rare in the general population. Endocrine and neurosurgery nurses would likely be familiar with the condition, the importance of the medication Mr Gorny was taking, and the crucial need to monitor his fluid balance. The nurses actually looking after him knew almost nothing about it.

It's a sad fact that there are a hell of a lot of medical conditions in the world. Patients with diabetes insipidus or the inability to produce steroid hormones are encouraged to wear MedicAlert jewellery to alert paramedics and medical staff to their conditions in case of emergency, yet it seems even when medical staff have access to full notes on a patient they can go unheeded. 

Sometimes it gets frustrating when you're in hospital or go to the doctors and are asked for the thousandth time to explain what's wrong with you. In the future I'll try to be more grateful that someone is checking...

Belated: Cushing's Disease Awareness Day

So it turns out that the 8th of April was Cushing's Disease Awareness Day, and I completely missed it. Not least because it was Easter Sunday, i.e. the first day I could eat chocolate again having given it up for Lent. It does seem cruelly ironic that the awareness day for a terrible disease, a key symptom of which is central obesity, should fall on a day that the rest of the world dedicates to filling their faces with fatty treats.*

Anyway, dedicated readers of my blog already know what Cushing's Disease is, but for everyone else: Cushing's Disease is caused by a tumour, known as an adenoma, on the pituitary gland. The tumour produces high levels of adrenocorticotropic hormone (ACTH) which can result in obesity, high sweating, hair loss, hypertension, diabetes, headaches, painful joints, and other not-so-fun symptoms. Treatment is chiefly through surgery and radiotherapy, as Cushing's is difficult to treat with medication.

There's a group of bloggers who suffer from Cushing's Disease who've been doing the "Cushing's Awareness Challenge", blogging on a different topic about their illness for every day of April. You can find out more about the challenge and read some of their blog posts by clicking here.

*Well, I do anyway.

A New Treatment for Cushing's Disease?

I've just been reading about a drug called Pasireotide. It's been around for a while, but on January 23rd this year, the European Medicines Agency's Committee for Medicinal Products for Human Use recommended that pasireotide be approved for use in the treatment of Cushing's Disease. This is exciting, because Cushing's Disease - in which a benign tumour of the pituitary gland causes the body to release excess steroid hormone - has long been very difficult to treat medically, with surgery and radiotherapy being the main treatments. But they're not always appropriate or successful for every patient.

Pasireotide (brand name Signifor, developed by Novartis) is a somatostatin analogue - like the medication lanreotide, which I take at the moment to prevent my own pituitary tumour from releasing thyroid-stimulating hormone. Like lanreotide and octreotide, the two somatostatin medications currently on the market, pasireotide looks likely to be effective in treating acromegaly and neuroendocrine tumours; unlike them, it appears to be much more effective at blocking tumours from producing adrenocorticotrophic hormone.

At the moment, there are no approved medicines in Europe for the treatment of Cushing's. Other drugs are used in practise, off-label, but with less data about their safety and effectiveness against the disease, so for Signifor to be approved would be a very significant step. The European Commission looks set to make its decision in the next few months.

The Wonderful Thing About Hormones, Is - SHUT THE HELL UP I HATE YOU

Now, as you may or may not have noticed, I am of the female persuasion. And one of the irritating things about this is that, when you get annoyed, no matter how legitimate your grievance, there are a few gentlemen dotted about the place who will always respond with "LOL IT MUST BE HER TIME OF THE MONTH HAHA WOMEN EH AND THEIR MYSTERIOUS HORMONAL PROBLEMS CAN'T LIVE WITH EM CAN'T KEEP EM ON A CONTINUOUS DIAZEPAM IV TO CORRECT THEIR CRAZY LADY ISSUES".

The trouble with this reaction is not just that it is stupid, but also that there is no way of responding to it that does not justify the accusation in the minds of the accusers. If you remain silent, it implies that you agree. If you punch them in the face, this is taken as further evidence of "hormonal imbalance", when in fact it is self-evidently the correct course of action.

But anyway, my experiences over the last year or so of undergoing treatment for my pituitary macroadenoma have certainly made me appreciate The Power of Hormones. And that's what we're going to learn about today.

So what are hormones? Obviously, as we all kind of slightly know, they're like chemically things that sort of slosh around your body, and if they get imbalanced then you go mental and start shouting at people and probably have a hot flush.

On closer examination, this sounds suspiciously like the theory of the four humours, so I turned to Wikipedia for a delightfully un-technical definition: "A hormone is a chemical released by a cell or gland in one part of the body that send out messages which affect cells in other parts of the organism… In essence, it is a chemical messenger that transports a signal from one cell to another."

The pituitary gland is a little gland at the base of the brain, and it sits around all day secreting nine different types of hormone which help to regulate growth, metabolism, water balance, lactation, aspects of preganancy and childbirth, body temperature, blood pressure and more. Given the complex feedback mechanisms required to keep all these hormones in balance, it's easy to see that when you develop a pituitary adenoma which secretes hormone(s), it throws everything completely out of whack.

Pituitary adenomas may secrete growth hormone (acromegaly), adrenocorticotropic hormone (Cushing's disease), prolactin (prolactinoma), or as in my case thyroid-stimulating hormone (TSH-oma). But then it gets complicated, because each hormone may interact with and affect the levels of other hormones as well. So, for example, in my case my body was producing too much thyroid-stimulating hormone, which caused my body to produce too much thyroid hormone, which had a knock-on effect on other hormones including prolactin and SHBG (technically not a hormone itself but a glycoprotein which affects the levels of other hormones in the body). It's basically like your body has spent ages laying out a complex pattern of dominoes on the floor, in which one starter domino needs to be flicked for them all to neatly fall over, and then some buffon comes tramping in wearing giant boots and stomps right in the middle of them. Lots of the dominoes fall over, some don't, and it's a bloody nightmare trying to set it all up again.

So, this time last year, my hormones were completely messed up and I was experiencing all kinds of crazy symptoms; rapid heartrate, hair falling out, massive appetite etc etc. And then I started treatment with lanreotide injections - the same injections that I'm having at the moment - and started to see an improvement in my TSH levels, which continued for several months and has only just got worse again (damnit!).

I already knew about The Power of Hormones. When your heart's going at 140bpm it's hard to ignore. But I hadn't really been prepared for the fact that when I began treatment, my changing hormone levels would affect me in more ways than simply improving my symptoms. The same thing has happened again in the past week or so since having my first injection. The first thing to arrive, just like last year, was the Crazy Appetite Swings. On Sunday, I had no appetite. I could happily have eaten nothing all day; just having a coffee in the morning made me feel really full. On Monday, I was back to normal; by Tuesday, I was completely ravenous.* There will probably be weeks of me alternately spending days completely uninterested in food, and then making like the Very Hungry Caterpillar and eating my way through anything placed in front of me, up to and including my own desk.

But the Crazy Hunger Swings are not so crazy as the Crazy Cat Lady Mood Swings. I guess I am fortunate in that my mood swings haven't tended too much towards the angry thus far,** but rather to the excessively emotional. For example, yesterday I was walking home from work, listening to my ipod as per usual, when all of a sudden and to my intense embarassment I burst into tears at a Beyonce song. I'm not going to say which song, out of shame, but the fact that I had this sudden surge of emotion struck me as rather hilarious and I then started giggling, so I was walking home laughing and weeping like a complete maniac and generally very glad I didn't see anyone I knew en route. I'm going to try my best not to adopt hundreds of cats and live in a bin liner, but at the rate I'm going the position of local madwoman may well be within my reach very shortly.

After a few more weeks of treatment, hopefully my hormones should be more in balance, but until that happy day every time my eyes well up with tears at the sight of a cute piglet in a teacup, I shall remember The Power Of Hormones.

Addisonian Crisis... or stressful football match?

I found an article on BBC News about how a woman was recently diagnosed with Addison's Disease, and one of the key clues to her underlying condition was her extreme response to the stress of watching particularly close and high profile football matches. They think that treatment for her condition may have cured her extreme reaction to tense games of football... but they can't be sure because her treatment and diagnosis has happened at the same time as a run of easy matches for her favourite team!

Addison's Disease is a medical condition which occurs when the body does not produce enough cortisol, a steroid hormone - basically it's the opposite of Cushing's Disease. Some people who suffer from pituitary problems due to a pituitary tumour, or after surgical removal of a tumour, are unable to produce ACTH, the pituitary hormone which stimulates the body's production of cortisol, and consequently they need to take steroids to make up for the lack of cortisol. The tricky part is that the body needs more steroid hormone when it's under stress, so when people who take steroids are sick or injured, they need to double their dosage.

After pituitary surgery, most people including me, go onto steroid replacement pills just in case there's been any damage to the part of the pituitary that produces ACTH, and take them until doctors are sure that the body is producing steroids naturally.

The aim of this is to make sure they don't suffer an Addisonian crisis, which is an acute medical emergency where there is a severe shortage of cortisol, usually in a high-stress situation. If untreated it can lead to death or coma, so people whose bodies don't produce cortisol on their own usually have some form of medical ID in case they're in an accident, to inform paramedics that they will need steroids immediately.

Performance-Enhancing Drugs

I'm proud to announce that, as of last Friday, I am no longer on steroids. Not because I don't care about maintaining a terrifyingly muscular physique a la Jodie Marsh*, but because my endocrinologist has, after stealing a lot of my blood, confirmed that six months after my surgery, my pituitary gland is successfully producing adrenocorticotrophic hormone (ACTH) on demand. Or, in layman's terms: The Surgeon Did Not Fuck Up.

This is good news, because ACTH is needed for the body to produce cortisol, which is needed for the body to not collapse, flail around, and then die. Consequently, it's generally thought that the safest thing to do is to give replacement cortisol treatment to everyone who's had pituitary surgery until you can be 100% sure they don't need it any more. As well as coming off the steroids, my monthly prescription bill will be further reduced over the next week or so as I wean myself off the beta blockers I currently take (to slow down my overenthusiastic heart).

Obviously I was delighted to hear that I would once again be eligible to compete in high-level international sporting events and resolved to do so at the earliest opportunity.** However, just days after I resolved to dig out my skipping rope and get cracking with some sort of training montage, I was surprised to find out that as long as I'm still on beta-blockers I'm excluded from taking part in some sporting events.

Having always associated beta-blockers with elderly folk post-heart-attack, I was surprised to find out that their effects, i.e. slowing heartrate and reducing tremor, are highly desired in, and consequently banned from, Olympic sports including gymnastics, shooting, wrestling, ski jumping (?) and curling.***

So I'll have to wait a few more days before starting my career as a wrestler. Damn.
