Hypothyroidism

Debate between Jane Ellison and Caroline Spelman

Tuesday 17th December 2013 Westminster Hall

[The Parliamentary Under-Secretary of State for Health (Jane Ellison)]

It is a pleasure to serve under your chairmanship, Sir Roger. I congratulate my right hon. Friend the Member for Meriden (Mrs Spelman) on securing a debate on this issue. This is, as she says, an opportunity to highlight something that we do not discuss often in Parliament. I hope that the debate will prove informative for those who wish to learn more about the condition, and will be useful to those who are affected in the way that she so ably described. I will mention the help and support that is available and will try to respond to the points that she made. If I am not able to respond to each point, I will write to her.

As my right hon. Friend said, hypothyroidism describes the general effects of a severely underactive thyroid gland, where not enough hormones are produced to keep the body functioning properly. The condition can be congenital, but most commonly occurs as a result of an autoimmune disease that attacks the thyroid gland and impairs its function. The condition is not uncommon, as she said. In the UK, the annual incidence of primary hypothyroidism is 3.5 cases per 1,000 women, and 0.6 per 1,000 men, so there is, as she said, a disparity between men and women.

The effects of hypothyroidism can be pronounced and debilitating, as my right hon. Friend said. Often, the condition goes untreated, because symptoms are frequently subtle and non-specific—she highlighted some—and may be wrongly attributed to other illnesses. Fatigue, weight gain, dry skin, lethargy, memory impairment and tiredness are all likely to be present. In elderly populations, symptoms such as memory disturbance, impaired mental state and depression may also be seen. However, the good news is that, for the vast majority of patients, once the right dose of hormone replacement treatment is given, they will return to a healthy state. Continuous medication is usually required to maintain that correct balance, and patients needing it are entitled to receive their prescriptions free of charge.

However, to get the right treatment and to restore the balance of health and well-being, a prompt diagnosis is, of course, crucial. My right hon. Friend focused on that. A range of guidance is available to improve awareness of the condition among both members of the public and health professionals. NHS Choices provides comprehensive advice on the causes, symptoms and treatment of the disease, and more detailed clinical guidance is available on the NHS clinical evidence website.

Best practice on the identification and management of hypothyroidism has been set out by the Royal College of Physicians in its guidance, “The Diagnosis and Management of Primary Hypothyroidism”, which was developed on behalf of key organisations, including the British Thyroid Association, the British Thyroid Foundation and the Society for Endocrinology. The guidance is endorsed by the Royal College of General Practitioners.

Clinical symptoms and signs alone are insufficient to make a diagnosis of hypothyroidism, so the RCP guidance makes it clear that the only validated method of testing thyroid function is blood testing, which must include measurement of the thyroid-stimulating hormone—TSH—and free thyroxine, or FT4, in serum. There is no evidence to support either the use of body fluids or the measurement of basal body temperature as a means of testing thyroid function. However, the guidance recognises that different methods of testing blood can give differing results, as my right hon. Friend mentioned. Highlighting in Parliament the RCP’s support for a helpful international initiative for greater harmonisation of reference ranges, and of the units used in expressing results of thyroid function tests, reinforces its thinking in that regard. My right hon. Friend is right to highlight that.

Once patients have been diagnosed with hypothyroidism, the vast majority can achieve successful management of their condition with a synthetic hormone replacement treatment. My right hon. Friend focused on the fact that some people do not get on with that treatment. The RCP guidance sets out that overwhelming evidence supports the use of thyroxine T4 hormone replacement—usually prescribed as levothyroxine tablets—alone in the treatment of hypothyroidism. The guidance does not recommend prescribing additional T3 hormone in any presently available form, including natural desiccated thyroid treatments, such as Armour Thyroid. This is because it has not been definitively proven to be of any benefit to patients and may be harmful. However, that does not prevent clinicians from considering other forms of thyroid hormone replacement, if appropriate.

For some patients, as my right hon. Friend highlighted, the wider availability of NDTs is a concern. It is worth making it clear that although this treatment remains unlicensed in this country, because the evidence base for its efficacy is unclear, GPs may prescribe it on a named-patient basis. I appreciate the push-back on inconsistency, but that is probably because it is unlicensed, so people have to find a GP willing to prescribe it on that basis.

To ensure that patients with the most severe and complex endocrine problems receive appropriate care and support, NHS England has published a service specification for complex endocrinology, setting out clearly what NHS England expects to be in place in order for providers to offer evidence-based, safe and effective care. That has been developed by clinicians and commissioners, with expert patient input. Certain patient groups have been calling for specialised training for endocrinologists and general practitioners in diagnosis and treatment. My right hon. Friend rightly focused many of her remarks on that.

Health Education England has responsibility for promoting high-quality education and training that is responsive to the changing needs of patients and local communities, and works with key stakeholders to influence training curriculums as appropriate. The curriculums of the Joint Royal Colleges of Physicians’ Training Board, which is responsible for the specialty of endocrinology, and the Royal College of General Practitioners, are both subject to regular review. As such, there are regular opportunities for stakeholders and interested parties, including parliamentarians, to express their views and influence the training of these clinicians. In light of the issues raised today by my right hon. Friend, I will write to the Royal College of General Practitioners, asking for its opinion on the guidance available to support its members in the diagnosis and treatment of hypothyroidism.

[Mrs Spelman]

My hon. Friend the Minister is coming towards the end of her remarks. Perhaps when she writes to the Royal College of General Practitioners, she will mention the excellent point raised by the hon. Member for Strangford (Jim Shannon). Where there is a family history of hypothyroidism, we should be thinking a bit more about prevention. When a patient presents with an ill-defined collection of symptoms, such a family history might set off an alarm bell in a GP’s head and precipitate a test, so that the hypothyroidism does not go undetected for so long.

[Jane Ellison]

That is a good point. There is some information on the NHS website, but I will certainly include that point in my letter, and hopefully I will get a response from the royal college, which I will pass on. The hon. Member for Strangford (Jim Shannon) takes a fantastic interest in health issues and, as ever, is here in his place.

I hope that the Chamber is pleased to hear that the National Institute for Health Research is funding a £164,000 study on whether people aged 80 or older with hypothyroidism would benefit from lower doses of hormone treatment. Older people often have the condition in a mild form, and may not have symptoms with adverse outcomes, so the current treatment might not be beneficial.

I always make the point in these health debates that the NIHR welcomes high-quality funding applications for research on any aspect of human health. My right hon. Friend the Member for Meriden highlighted some areas that she feels would benefit from further research, and I can only say that the NIHR’s door is open to high-quality bids in any of those areas. That might be worth passing back to the charities and experts working in this field.

As I come to my conclusion, I reassure the Chamber more generally about the Government’s commitment to improving outcomes for the 15 million-plus people living in England with long-term conditions, including hypothyroidism. Through the NHS mandate, we have asked NHS England to make measurable progress towards making the NHS among the best in Europe at supporting people with ongoing health problems. We want such people to be able to live healthily and independently, with much better control over the care they receive. Of course, that feeds into many other priorities, such as ensuring that people do not present at accident and emergency because the management of a long-term condition has gone wrong. We want to ensure that such people can be healthy, well and looking after themselves without getting to that stage.

The various improvement areas mirrored in the NHS outcomes framework—this is relevant to the point on local doctors—are also in the clinical commissioning group outcomes indicator set, so CCGs are also held to account for, and are asked to provide information to the public on, the quality of the services and health outcomes that they achieve through commissioning for people with long-term conditions.

At a service level, the new NHS improvement body, NHS Improving Quality, has made the development of evidence-based tools for the management of long-term conditions the subject of a key improvement programme for 2013-14. The interventions under consideration include care plans, care co-ordination, the use of technology, self-care and the role of carers. That work will be evaluated, with best practice identified, to help us drive improvement across a range of long-term conditions. I am sure that some of the conclusions reached and evidence gathered by NHS Improving Quality will be relevant to hypothyroidism.

In conclusion, I thank my right hon. Friend once more for securing today’s debate. I hope this discussion has been helpful in providing some reassurance on our commitment to improving the quality of life for all those with long-term conditions such as hypothyroidism. I will, of course, write to her to follow up on this debate, which I hope will both help her to reassure her constituent and add to the wider debate.
