How do people with adrenal insufficiency determine if we are on enough or too much hydrocortisone?

One of the comments to my last post, Rant: The prescribing and adherence to low doses of cortisol,  asked the question "How do people with adrenal insufficiency determine if we are on enough or too much hydrocortisone?"  You would think that there was a cut and dry answer to this question.  There is no blood test for cortisol. There are no accepted guidelines to determine the correct amount of cortisol in the blood taking into account the many factors that can affect cortisol assimilation into the blood:

• Circadian rhythm of cortisol (at what time should what serum cortisol number be achieved?)
• At what time would this number be achieved depending upon a person's individual metabolism of the cortisol?
• Does gender matter for cortisol?  Place in the woman's cycle?  Post menopausal?
• HRT or estrogen replacement has effects on cortisol binding proteins
• How do the comorbid conditions affect a person's need for a higher or lower cortisol number?
• Does a person's digestive issue affect the amount of cortisol needed to attain a specific amount of cortisol in the blood? 

There are many more factors to consider.  The factors are technical.  What it comes down to is, what is a realistic way to determine if we are taking enough cortisol?  Yes, symptoms or lack of determine the "right" amount of hydrocortisone replacement.

Symptoms of adrenal insufficiency and under replacement of hydrocortisone:

• Hyperpigmentation
• Low blood pressure/orthostatic hypotension
• Nausea/vomiting/diarrhea
• Poor immunity, particularly with lung involvement
• Low blood sugar
• Fatigue
• Depression or crying at Hallmark commercials
• Serum indications 
• Elevated serum calcium
• Low sodium/high potassium
• Low lymphocytes
• High esinophils
• Low WBC
• High hematocrit

If you are not taking enough hydrocortisone, you will suffer from a few of the symptoms of adrenal insufficiency (see the list above).  You do not have to have each and every one of the symptoms to say, "Hmmmmm, I might not be on enough cortsiol!"  We all have different comorbid conditions and different physiologies that cause us to have different symptoms from one another.  I have only included the serum indicators for those of you who can't believe your symptoms.  Maybe you need to have someone else tell you (like a lab) that what you are feeling is valid.  The "serum indications" list is for you.

What can you do now that you've determined that you might not be on enough HC?

• Get your doctor's permission to make changes to your dosing strategy
• discuss timing
• discuss dosing
• discuss your symptoms
• discuss what constitutes a successful/failure of a trial
• discuss length of trial
• Get a journal where you record
• symptoms
• sleep
• medications, doses and times
• Set up a dosing schedule, see this rant for tips  Really, how hard is it? (An Addison's rant)

• Keep in mind you can only metabolize a certain amount of cortisol from hydrocortisone at one time.  5 mg and 10 mg doses are the most readily assimilated. 
• 2/3 of your dose should be before noon
• You will probably need to take your HC more often than you are now.  Separate doses by 2 or 3 hours
• Take your HC consistently
• Don't cut your trial short based on a one-off reaction.  Remember this quote, "

  “Once is happenstance. Twice is coincidence. Three times is enemy action"― Ian Fleming

The nice thing about hydrocortisone is that it's short acting.  Dosing is reversible.  If you decide to change your dose of HC (WITH YOUR DOCTOR'S PERMISSION) and it seems like too much, you can take less later in the day and the next day.  You don't have to stick with a dose that doesn't work for you.  Easy!

Symptoms of over replacement of hydrocortisone:

• Immediate
• Feeling jittery
• Anxiety
• Overstimulated
• Easily angered/frustrated
• Long term
• Weight gain that's inappropriate to food intake/exercise
• Purple striae
• Insomnia
• High blood sugar
• Moon face/buffalo hump

Symptoms of correct replacement of hydrocortisone:

• Fatigue that's appropriate to your activity level
• Sleeping well
• Appropriate digestion with regard to your other diseases
• Consistently good blood sugar
• Consistently good blood pressure
• Good mood
• Good immunity
• When I'm feeling really well, I think, "Are these meds actually doing anything?  Are they placebos?"  For me, this is a sign that my meds are balanced well!!!

Rant: The prescribing and adherence to low doses of cortisol

People who are diagnosed with adrenal insufficiency should be taking the lowest possible dose of hydrocortisone (HC) possible.  Fact.  What is the lowest possible dose?  It all depends upon your physiology, your diagnosed and undiagnosed comorbid conditions and the amounts of other hormones you are on.

How does your doctor determine how much HC you should be on?  Pathetically enough, he basically pulls a number out of his ass with no regard for your quality of life or clinical symptoms.  He likes to err on the side of a lower dose and very poor quality of life.  The generally recommended guidelines in medical literature are about 15-25 mg of HC per day without any regard to activity level, binding globulins, other hormones you are taking that affect cortisol metabolism or the other diseases you have.  

I know of very, very few people who can function well on 15 mg of hydrocortisone a day.  I know of only a few.  Some have decent quality of life.  Some do not but prefer to suffer from all of the symptoms of under replacment:  bronzing, nausea, vomiting, low bp, fatigue, hypoglycemia.  In addition, cortisol is needed for bone growth.  Not enough cortisol INCREASES your risk of osteoporosis so if you think you're doing yourself favors by suffering through the symptoms of under replacement to make your doctor happy, you are actually a martyr and a little suicidal.  

The average replacement dose is about 20 mg of HC per day.  The recommendation is based on nearly nothing.  There is no monitor for cortisol that's widely available to the public.  There are no guidelines for cortisol numbers based on the dose, patient's metabolism, comorbid conditions and time of the last dose.  The 20 mg of HC number was collected in a hospital setting on people who sat around all day getting blood drawn.  When's the last time you sat around all day, chatting, reading magazines and waiting to have blood drawn?  Most of us don't have that sedate or stress free of a life and need more cortisol to mow the lawn, take care of kids, work full time, fight with our spouses and exercise. 

If you find that you need more than 20 mg of HC per day to function well, don't let your doctor tell you you will be over replaced with cortisol if you take more.  Some of us have active lifestyles, stressful lifestyles and/or thyroid (GH too) replaced at too high of a dose for someone who only has a fixed amount of cortisol in her system.  Know the symptoms of over replacement.  Tell your doctor what they are and which ones you don't have from deviating from his recommendations.

It is far more dangerous for you to be under replaced than properly replaced.  You are unable to store glycogen in your liver if you do not have enough hydrocortisone.  If you do not have glycogen stored in your liver, you will more easily become hypoglycemic.  Hypoglycemia is when you don't have much sugar in your blood.  The sugar in your blood feeds your brain and muscles.  You can die from severe hypoglycemia.  

If your doctor is only prescribing the bare minimum of hydrocortisone, how do you keep a small stash in your wallet, gym bag, desk or purse?  What do you do if you vomit and need to triple your HC dose?  How do you increase your HC for exercise?  Heaven forbid you get a fever and need to double or triple for days in a row?  If you're willing to share your strategies on this, I'd love to hear them.

Rant: "Normal" cortisol results and cortisol testing.

"Treatment surveillance of chronic glucocorticoid replacement is mainly based on clinical grounds because no objective assessment has proven to be reliable for monitoring replacement quality. ACTH cannot be used as a criterion for glucocorticoid dose adjustment, since in primary adrenal insufficiency it is invariably high before the morning dose and rapidly declines with increasing cortisol concentrations after glucocorticoid ingestion.122,124 Aiming at morning ACTH values continuously within the normal range would, therefore, lead to chronic overreplacement."

 Arlt, W., & Allolio, B. (2003). Adrenal Insufficiency. Lancet, 361, 1888

It is clear in the adrenal insufficiency literature that cortisol ranges are useless for determining a patient's cortisol replacement needs yet uneducated, poorly read doctors continue to ask their patients to submit and pay for cortisol and ACTH testing to determine the patient's replacement needs.  There are no reference ranges for cortisol replacement!  How can any determinations be safely made by your physician if there is no data?

A doctor will ask you to get a morning cortisol test and sometimes ACTH.  Did he tell you how much HC to take?  Did he tell you when to take it?  Does he have literature to determine what the proper numbers should be based on dosage of HC and timing of the dose (the answer to this is NO because it does not exist.  If you have access to this literature and I am wrong, PLEASE post a link in the comments.  I want to be wrong about this.)

The way you feel and your symptoms have to determine cortisol replacement.  Doctors constantly want us to take lower and lower doses of HC but the medical literature says replacement needs to be based on "clinical grounds".  The Arlt and Allolio quote is just one of many reinforcing this position.
A well meaning doctor might ask you to pay for an ACTH serum test to help you determine your cortisol replacement.  He's misinformed.  ACTH is a poor indicator of cortisol replacement and getting this test done can actually harm you if the results are interpreted incorrectly...and they will be interpreted incorrectly.  Your doctor might suggest you start taking less HC or more without taking your "clinical grounds".  Duh!  Are you constantly nauseous, have diarrhea, hypoglycemia and/or low blood pressure but your ACTH draw is low?  Does your doctor want to lower your HC dose based on the ACTH result but not want to pay attention to the fact that 1)  ACTH can't be used to determine HC replacement  2)  it has to be done under specific lab conditions and it probably wasn't  3)  it has to be done first thing in the morning  4) ACTH is pulsitile and fragile so even under the best of circumstances, it can still have an abnormally low result.

Enough about the futility of the meaninglessness of ACTH results.  On to the dangerous misinterpretation of cortisol testing in the undiagnosed.

Doctors will often randomly test cortisol in the undiagnosed yet have NO CLUE as to what the results should be.  They look and see if the lab flags the result as "High" or "Low".  This is one of the most misleading and dangerous things an uneducated doctor can do.  The range is usually 2-20 (give or take, depending upon the lab).  Anything that falls within that range is considered "normal".

Let's look at the "normal" range more closely.

A morning cortisol (8 am) should be somewhere around 20 with the person being asymptomatic for adrenal insufficiency.  An 8 am cortisol of 15 or lower (in someone who is undiagnosed) is a reason to run an ACTH stim test.  Let's just use a little common sense here. A decent morning cortisol should be 16-20ish based on the fact that a cortisol of 15 or lower is grounds to run an ACTH stim test.

A midnight cortisol should be 2-4.

If you have an 8 am cortisol of 12 and a doctor who doesn't know that the cortisol reference range is 2 at midnight and 20 at 8 am.  You're screwed and dismissed as normal despite all of your other symptoms that correspond with adrenal insufficiency.  You are a victim of the "normal" reference range.

Get copies of all of your labs.  Study them.  Learn what they mean.  Search out health forums (mine is free) and get help.  I can provide assistance and guidance if you want to pay for it.  If you suspect you have adrenal insufficiency, you are probably right.  It's hard to convince a physician who only sees "normal" numbers.  All of the numbers need to be taken into account, so do symptoms and past labs.
