Background Fourteen clinical trials have not shown a consistent benefit of combination therapy with levothyroxine (LT4) and liothyronine (LT3). Despite the publication of these trials, combination therapy is widely used and patients reporting benefit continue to generate patient and physician interest in this area. Thyroid antibodies measured will include thyroid stimulating immunoglobulin (TSI), thyrotropin-binding inhibition antibody (TB II), thyroid peroxidase antibodies and thyroglobulin antibody. Other tests including the full blood count, urea and electrolytes will be run prior to each dose of steroid treatment and during follow-up to monitor for. Thyroid Disease Clinical Trials.

Every day over one million people in the UK take the thyroid hormone Levothyroxine sodium (L-T4) for an underactive thyroid (hypothyroidism). The goal of therapy is to
- restore well-being
- normalise the serum thyroid-stimulating hormone (TSH) level
- TSH being the hormone which is secreted by the pituitary gland and which regulates thyroid hormone (thyroxine (T4) and triiodothyronine (T3)) production.
Most patients respond satisfactorily but a minority of treated individuals experience persistent symptoms despite adequate biochemical correction. The care of such individuals is challenging and remains the subject of considerable public interest.
Diagnosis and Evidence
The diagnosis of primary hypothyroidism is based on the clinical features of hypothyroidism supported by biochemical evidence of an elevated serum TSH together with low free T4 (overt hypothyroidism).
The earliest evidence of an underactive thyroid (hypothyroidism) is an elevated serum TSH.
About serum TSH levels
There has been a growing controversy about the upper limit of the reference range for serum TSH and at what point patients actually benefit from thyroid hormone replacement.
To establish a 'normal' reference range in the first place we look at large group of people who do not have thyroid disease and are otherwise well. By convention this only comprises 95% of a reference population.
Therefore it is understood that, 2.5% of ‘normal' individuals will fall above the reference range and 2.5% will fall below the range.
By doing this the reference range for serum TSH in thyroid- disease- free individuals is accepted as between 0.4 and 4.0 mU/l.
Studies and Trials
Studies addressing the relationship between symptoms suggestive of thyroid hormone deficiency and the biochemical finding of a mildly elevated TSH and a normal T4 (subclinical hypothyroidism) have produced conflicting results.
What's more, in randomised controlled trials, there is inconsistent evidence for the benefit of thyroid hormone treatment in subclinical hypothyroidism.
The conclusion is that Primary hypothyroidism should not be diagnosed in individuals with a serum TSH within the population reference range and who have intact pituitary function.
Thyroid Function
The healthy thyroid produces mainly T4 and much smaller amounts of the physiologically more active T3.
Approximately 80% of T3 is provided by conversion of T4 to T3 with the remaining 20% of the T3 secreted direct from the thyroid.
In contrast, people with hypothyroidism are treated with T4 alone, so all of their T3 is produced as a result of conversion from T4.
It has been suggested that one reason why some people are not happy with L-T4 treatment is that they are not getting their supply of T3 in a physiological way, as all of it is coming from the conversion from T4.
So would patients be better off with potentially more physiological combination treatment with synthetic human L-T4 and L-T3 than with L-T4 monotherapy?
In considering this The British Thyroid Association recently published a peer-reviewed position statement in the leading UK endocrine journal Clinical Endocrinology on the management of primary hypothyroidism. See here
This is based on a review of the recently published positions of the American Thyroid Association (ATA) and the European Thyroid Association (ETA); upon current literature and upon the best principles of good medical practice.
This statement has been endorsed by the Association of Clinical Biochemistry (ACB); the British Thyroid Foundation (BTF); the Royal College of Physicians (RCP); and the Society for Endocrinology (SFE).
In brief the conclusion is that the benefits of combination therapy with LT-4 and LT-3 are still unproven, and the potential for harm exists with unregulated use of unapproved therapies especially the lack of long term L-T3 safety data and the unavailability of L-T3 formulations which accurately mimic natural physiology.
Our advice to the medical community
People may now have high expectations about how energetic they should feel, but that does not mean that tiredness and depression should be ignored.
It has been demonstrated that up to one-quarter of the healthy population have the non-specific symptoms associated with thyroid failure such as lethargy and weight gain. However, patients should be thoroughly evaluated for other modifiable conditions such as other autoimmune conditions and mood disorders.
This may mean that in some cases a retrospective review of the original diagnosis of hypothyroidism may prove to be necessary.
Symptom and lifestyle management support should be provided and further dose adjustments may be required.
L-T4 is considered the most effective hormone replacement that has yet been devised for endocrine conditions, but there are undoubtedly people who fall outside the current treatment model.

Animal-derived products that contain T4 and T3 are not physiological and are not the answer in the longer term, but we do need to find ways to ensure that all our patients with hypothyroidism feel the full benefits of replacement therapy.

Thyroid Awareness
Have you been feeling tired, gaining weight, or feeling depressed? Have you been losing weight without trying to, feeling jittery, and having trouble sleeping?
These types of symptoms can be caused by many different things, including thyroid conditions. If you have these symptoms you should discuss them with your primary care provider to see if you need to get your thyroid checked. The thyroid is a gland in your neck that controls your body's rate of metabolism. Women are up to 5 times more likely than men to have a thyroid condition.
January is National Thyroid Awareness Month, and VA Women's Health Services wants to make you aware of thyroid conditions – how they can affect your health and when to ask your provider about getting a thyroid check. Thyroid conditions are very common among women. A national U.S. healthcare quality survey found that about 13 million women ages 18 years and older received treatment for a thyroid disorder in 2008. Of women Veterans who used VA healthcare services, 6.6% of women ages 18-44 years, 15.2 % of women ages 45-64 years, and 23.3 % of women age 65 years and older received a diagnosis of a thyroid condition 2012.
There are two main kinds of thyroid disorders, hyperthyroidism (overactive thyroid) and hypothyroidism (underactive thyroid).
Hyperthyroidism, or an overactive thyroid, is caused by the thyroid gland producing more thyroid hormones than the body needs. Hyperthyroidism is commonly caused by Graves' disease, Thyroid Nodules, Thyroiditis, or some medications. Symptoms of hyperthyroidism include:
- Weight loss
- Diarrhea
- Palpitations
- Feeling anxious or jittery.
- Increased sweating
- Feeling hot
- Trouble sleeping
- Changes in your period (usually lighter)
Treatment options include anti-thyroid medicines, radioactive iodine, or surgery.
Hypothyroidism, or an underactive thyroid, occurs when the thyroid gland does not make enough thyroid hormones. Hypothyroidism is most commonly caused by Thyroiditis, having the thyroid removed, radioactive iodine treatment, and some medications. Symptoms appear gradually and include:
- Weight gain
- Feeling Cold
- May reduce your risk for osteoporosis later in life.
- Constipation
- Depression
- Fatigue (feeling very tired)
- Hair Loss
- Changes in your period (usually heavier)
Treatment is taking thyroid medication (a pill) daily to provide your body with the right amount of thyroid hormone.
Thyroid Cancer can sometimes occur in thyroid nodules although most thyroid nodules are benign. Thyroid cancer is more common in people who have a family history of thyroid cancer, are older than 40 years old, and have had a large amount of exposure of the thyroid to radiation. This type of cancer is treated by surgery and radioactive iodine.
Thyroid disorders and Pregnancy
Hyperthyroidism and hypothyroidism can make it more difficult for women to become pregnant and can also cause problems during pregnancy if they are not treated. Pregnant women with thyroid conditions take medications to keep their thyroid hormone levels in the normal range during pregnancy. It is important for pregnant women to have their thyroid checked to see if the medication dose needs to be adjusted. Thyroid hormone levels that are too high or too low during pregnancy increase the risk for harm to a mother and her developing baby. If the thyroid levels are controlled during pregnancy women with thyroid problems will have normal healthy babies.
If hyperthyroidism is not properly treated during pregnancy, women have an increased risk of:
- Miscarriage
- Heart failure
- Preeclampsia
- Early (preterm) labor and birth
- Stillbirth
- Baby with a low birth weight
- Increased heart rate in the developing child
- Baby with thyroid problem or goiter
If hypothyroidism is not properly treated during pregnancy, women have an increased risk of:
- Preeclampsia
- Anemia
- Baby with a low birth weight
- A lower IQ in the baby
- Too much bleeding after delivery (postpartum hemorrhage)
Thyroid disorders and breastfeeding
Women treated with medication for overactive and underactive thyroid disorders are able to breastfeed their infants normally.
How are thyroid disorders diagnosed?
Thyroid disorders are sometimes hard to diagnose, because symptoms of over-active and under-active thyroid may be similar to those associated with aging, depression, or other life events. If you report symptoms to your provider that could be due to a thyroid condition, your provider will start by taking a complete medical history to learn more about your symptoms and yourfamily history. Then, your provider will examine the size and shape of your thyroid to see it is enlarged and if there are any nodules (bumps). Depending on your symptoms and your exam, your provider may order blood tests. Based on your physical exam and the results of your blood tests further testing such as a thyroid ultrasound or thyroid scan might be indicated.
