On April 11, 2016 an article, Doctors Hear Patients’ Calls for New Approaches to Hypothyroidism, appeared in the Wall Street Journal regarding the growing influence of patient preference on treatment selection for hypothyroidism (sluggish thyroid). The article was written by the WSJ health columnist Melinda Beck. I might have missed it but thanks to a motivated patient I received a copy within a week after its publication. With a glance I knew this report could be a highly significant addition in the on-going debate between specialists treating hypothyroidism (endocrinologists) and advocates of alternative approaches.

According to experts, 10 to 20% of hypothyroid individuals fail to respond completely to T4-only (levothyroxine, Synthroid) treatment. Dr. Anthony Bianco, the president of the American Thyroid Association, and his associates believe this is due to genetic variations in the way thyroid hormone is converted in the body from T4 into T3. T3 is the much more potent form of thyroid hormone and unless the cells of the body receive enough T3, normal function cannot be achieved and symptoms of low thyroid such as fatigue, mental fogginess, constipation, muscle aches etc, persist. Based on the research conducted by Dr. Bianco and colleagues it is thought that in those with the genetic trait making T4 treatment ineffective, blood tests would show low T3 levels. Continue reading

Tara’s message: “I was diagnosed with Grave’s Disease in 2009, I had RAI in 2011, after my daughter turned 3 months. Being pregnant with Severe Grave’s was the scariest thing in my life at the time. I gained weight prior to my pregnancy, during, and after RAI. My family doctor told me no matter how much you ate while severe Hyperthyroid you should have been anorexic, so something else is wrong. ” Continue reading
Why Patients Aren’t Receiving the Most Effective Treatment for Hypothyroidism
By Gary Pepper, M.D.
For the past 3 to 4 decades endocrinologists worldwide have adhered to the belief that only synthetic T4 (the most abundant of 4 thyroid hormones produced by the thyroid) is appropriate therapy for a sluggish thyroid even though it is known that a substantial number of those treated with T4 only continue to suffer from persistent symptoms of the disease. This may be because under normal conditions the thyroid produces two principle hormones T4 and T3. In 2013 an NIH study showed that 50% of those with hypothyroidism preferred treatment which includes T3 and our group reported that 78% of a subgroup of patients preferred T3 containing medication to treat hypothyroidism .

Mainstream endocrinologists seem to be moving grudgingly toward acceptance of combination T4 plus T3 therapy for hypothyroidism. A great example of the mixed feelings harbored by endocrinologists in this regard is the title of a recent editorial, “ Combo (treatment) a Last Resort for Hypothyroidism” . Although the author, Dr. Bruce Jancin of the University of Colorado, recognized the value of combination T4 plus T3 therapy, he did so with the least possible enthusiasm. In his article the doctor acknowledged the weakness of scientific studies showing negative results with combination therapy and pointed out the findings of the Watts Study which provides a genetic rationale for why some people need to have T3 added to T4 to return to proper thyroid hormone balance.

Michelle shares her success story with T3. Michelle’s story demonstrates how combination therapy with T4 and T3 can be clinically superior to T4 (Synthroid, Levothyroxine) alone. In her story she mentions Wilson’s syndrome which I personally think is a “made up” diagnosis to help Dr. Wilson’s retirement fund but I do think her experience is fairly typical of a lot of people with hypothyroidism who eventually discover they need T3 added to conventional treatment with T4 to achieve best results.
OMG! Maybe I’m not crazy after all!
I’m 47 in December and can’t remember the last time I felt good or even okay. Same thing – doctors repeating same tests, thinking I’m exaggerating, sent to Psychiatrist…Over the past 6 years or so, major stress, low immune (sick all the time), worsening depression, borderline diabetes, high blood pressure, peri-menopause. Got to the point that I’m sooo exhausted. Don’t want to do anything. Lab diagnosis finally showed up hypothyroidism so doctor put me on Synthroid – I was so happy that I cried. Devastation set in after 6 months as this was not the miracle I thought it would be.
Started taking my temperature 3 to 4 x a day as suggested to me by a naturopath I had seen but couldn’t afford to keep going to. Again, measurements taken 3 x daily for a week averaged to 97.0. Talked to doctor about Wilson’s Temperature Syndrome; she did not believe in it and sent me for more blood tests which came back normal.
FINALLY (after 20 years at same doctor’s office) was lucky enough to be accepted under the care of a physician who hadn’t heard of WTS but had heard about the T4 not converting into the T3 (you all know the fault in the system)… so right then and there wrote me a prescription for Cytomel and told me to stop the synthroid. As the WTS website recommends sustained T3, I’m taking half the dose every 12 hours.
I started today and feel like a kid on Christmas Eve a million times over! I am so hopeful that this can get to the root of so many ailments. So many that I feel that I’m not even living my life, that I’m just here putting in everything I have just to get through the day.
With the lack of memory and concentration I have right now, I hope I remember to come back to this site and update you all!
When I became an endocrinologist in 1981 I was truly excited about the field. At that time it seemed that the science of endocrinology was expanding rapidly and new discoveries were on the horizon particularly in regards to the way hormones effect the brain, mood and the immune system. Was I ever wrong! It’s thirty years later and none of those expectations were realized. In fact, I find that the field of endocrinology has barely budged since then and in some areas has actually lost ground.
Bringing on this round of pessimism on my part, is a recent “development” in the area of treatment for hyperthyroidism (over active thyroid). Ever since I was in training there have been two medicines, propylthiouracil (PTU) and methimazole (Tapazole), which are the mainstays of medical treatment for hyperthyroidism. Both medicines have been available since the 1940’s and show excellent efficacy and tolerability (and they are cheap!). Almost all endocrinologists I have met use these two drugs interchangeably although in pregnancy propylthyiouracil is favored due to rare birth defects in fetuses exposed to methimazole.
The “development” which I find so discouraging is the recent action by the FDA to place a very strict (black box) warning on the use of PTU due to the possible occurrence of a rare form of liver injury attributed to the drug. After almost 70 years of exemplary use, this has given rise to extensive debate in the endocrinology literature about how to restrict PTU use.
While it is true that methimazole is equally as effective as PTU to treat hyperthyroidism, I have personally seen numerous cases of fairly severe allergic reactions to methimazole. Fortunately it has been easy to continue medical treatment by simply switching to PTU. If we can’t use PTU freely then the only other options are surgical removal of the thyroid or eradication of the thyroid using radioactive iodine, neither of which is free of potentially adverse outcomes.
I have never encountered severe liver injury with PTU nor has any of the colleagues I have polled. It has to be very, very rare. This is obvious because it has taken 70 years to get around to recognizing it formally. Can we really call it progress that we now have one less simple option for treating hyperthyroidism, a common and relatively benign disease? Let me take my cynicism to the next level. I won’t be surprised if a major pharmaceutical company soon announces the development of a new drug for treating hyperthyroidism. If I’m right the new drug will add nothing of real value that wasn’t previously available but is many times more expensive then the drug it replaces.
So goes endocrinology into the new century, the stogy old lady of medicine.
