For decades doctors have recognized synthetic thyroid hormone known as levothyroxine or brand name Synthroid, as the undisputed choice for treating hypothyroidism (low thyroid function). By virtue of hypothyroidism being extremely common levothyroxine has been the most prescribed medication in the U.S.
According to key medical organizations in this country, the only acceptable treatment of hypothyroidism is the use of levothyroxine alone. Using any other form of therapy is not recommended. Pointing to a significant number of patients receiving levothyroxine who continue to complain of symptoms of hypothyroidism health advocates have been calling for recognition of alternative treatments. One such alternative with a small but enthusiastic following is extract of pig thyroid (desiccated thyroid extract). All of the major organization of endocrinologists fail to recommend this form of treatment but in particular the American Association of Clinical Endocrinologist or AACE in the US has flatly stated this form of therapy should never be used. Physicians and their patients remain deeply divided on this issue.
In the spring of 2017 the American Thyroid Association (ATA) convened a symposium on treatment of hypothyroidism and determined that “it is important to describe the patient perspective regarding hypothyroidism treatment and to share it†with the medical community. Now, after an enormous expenditure of time and effort, the results of their survey of patients being treated for hypothyroidism were published on-line. The full report in print will become available in the coming months. Here are some to the highlights of the ATA analysis of over 12,000 participant responses.
Overall satisfaction with the present choices of thyroid hormone treatment is 5 out of a possible 10Treatment satisfaction with desiccated thyroid extract (DTE) such as Armour and NP Thyroid was highest at 7 out of 10.
Lowest satisfaction was with levothyroxine or Synthroid alone at 5 of 10
Treatment with levothyroxine plus t3 (Cytomel, tri iodothyronine) was next best at 6 out of 10
Patients taking DTE were less likely to report problems with weight management, fatigue, mood and memory as compared to levothyroxine alone or levothyroxine plus t3
The authors conclude, “a subset of patients with hypothyroidism are not satisfied with their current therapy or their physicians†and “higher satisfaction with both treatment and physicians is reported by those patients on DTEâ€.
After decades of dispute among physicians themselves about the best ways to treat hypothyroidism, patient are finally having their say. Some readers of this blog may have been among the participants in the survey and deserve great credit for sharing their experience with the medical community. It is hoped that this survey will mark a turning point in the discussion about treatment of hypothyroidism and help to forge a change in the way physicians approach this very common and often disabling condition.

I am reporting to you from this year’s meeting of the American Thyroid Association now taking place at the opulent Breaker’s Hotel in balmy Palm Beach, Florida. Cushy job if you can get it, I’d say.
Not a lot of laughs during the typical lecture at this three day meeting of the world’s experts on thyroid diseases and treatment but I did hear a few guffaws, giggles and snorts today during the single lecture devoted to using combination t4 and t3 therapy for treating hypothyroidism. The speaker on this topic, Dr. Michael McDermott a Professor of Medicine and Pharmacy at the University of Colorado, was actually significantly more open minded about using combination t4/t3 therapy then speakers from previous meetings on the same topic. He prefaced his comments by acknowledging that about half of patients treated with synthetic t4 continue to experience symptoms typical of thyroid hormone deficiency. What, if anything, doctors are to do to help their patients in this situation appears to still mystify the experts.
The laughs came when Dr. McDermott polled the audience of professionals about their opinions regarding treatment of a hypothetical hypothyroid patient with normal thyroid function blood tests continuing to complain of symptoms suggestive of thyroid hormone deficiency. The speaker put up a slide with 5 or 6 treatment options which the audience then voted on. Although a good portion of experts here gave a philosophical shrug of the shoulders by not choosing any of the options, it was reassuring to see a significant portion of the audience agreed with the statement that some hypothyroid patients appear to improve when t3 is added to traditional t4 treatment. This is far short of a strong endorsement of combination therapy but I would say it is a least a nod to those of us who routinely make use of this treatment option. The laughs and giggles came when the next to last option was read to the audience, proposing that Armour Thyroid was the best choice of treatment in this case. The last choice, that this type of patient should see a psychiatrist also got a few chuckles.
Not much more about dessicated thyroid treatment was mentioned after this curt dismissal but Dr. McDermott expressed his opinion that Armour Thyroid was a poor choice for treating hypothyroidism because it contains too much t3 and that synthetic t3 should be used exclusively if combination therapy was attempted. No one seemed aware that as of this month Armour Thyroid and similar dessicated thyroid medications were no longer available in the United States.
Despite the disturbing aspects of the first part of Dr. McDermott’s lecture he did end with some exciting ideas that I will soon be reporting on. The main idea he reviewed is that a genetic defect may cause resistance to t4 treatment in hypothyroidism. Those with the genetic defect would require the addition of t3 to achieve a healthy thyroid balance and elimination of the symptoms of hypothyroidism. I am sensing that this may be a breakthrough in thinking about why some people require combination therapy with t4 and t3. If so, endocrinologists will be forced to reconsider their reluctance/refusal to provide combination therapy for treatment of their symptomatic and dissatisfied hypothyroid patients. More to come on this breakthrough in my next installment.
