Who is it for? In patients with toxic multinodular goiter or a solitary … A particular concern about the strong conclusion and high TSH threshold for intervention in this meta-analysis is that primary care physicians may now dismiss patients with subclinical hypothyroidism rather than institute ongoing surveillance, potentially resulting in some patients with progression of hypothyroidism being deprived of treatment. This recommendation also ignores strong observational data that there may be an age interaction with regard to treatment response2. Beside serum TSH cutoff levels, the presence of symptoms and signs of hypothyroidism should be checked before starting any treatment. Natural thyroid extract does not have a UK marketing authorisation so its safety is uncertain. Local commissioners and providers of healthcare have a responsibility to enable the guideline to be applied when individual professionals and people using services wish to use it. Previous guidelines suggested that levothyroxine treatment may be appropriate with hypothyroid symptoms or a TSH level exceeding 10 mIU per … The treatment of subclinical hypothyroidism is seldom necessary. 2015;4:149–63. Both SfE and BTA disagree with the conclusion that most adults with SCH do not require treatment, as the guideline does not provide sufficient evidence, especially in younger individuals, to support this claim. A more important conclusion from this meta-analysis is that carefully conducted trials of subclinical hypothyroidism, particularly in younger individuals (aged <65 years), are urgently warranted. Guidelines generally recommend thyroid hormones for adults with TSH levels above 10 mIU/L. 11, 14 Treatment should also be initiated in … 1st December 2019 Radioiodine has been used very effectively to treat thyroid overactivity since the 1940’s, but a recent study has cast doubt on its safety, causing considerable concern. Do not routinely offer liothyronine for primary hypothyroidism, either alone or in combination with levothyroxine, because there is not enough evidence that it offers benefits over levothyroxine monotherapy, and its long-term adverse effects are uncertain. NICE guidance and other sources used to create this interactive flowchart. The recommendations in this interactive flowchart represent the view of NICE, arrived at after careful consideration of the evidence available. Everything NICE has said on thyroid disease in children, young people and adults in an interactive flowchart. BMJ 365, l2006, doi:10.1136/bmj.l2006 (2019), 2          Razvi, S., Weaver, J. U., Butler, T. J. High frequency of and factors associated with thyroid hormone over-replacement and under-replacement in men and women aged 65 and over. The most common cause of subclinical hypothyroidism is a condition known as Hashimoto thyroiditis, a disease that involves inflammation and damage to the thyroid gland because of antibodies against a person’s own thyroid gland.A number of other conditions can cause subclinical hypothyroidism, including having had thyroid surgery in the past and having … Commissioners and/or providers have a responsibility to provide the funding required to enable the recommendations to be applied when individual health professionals and their patients wish to use it, in accordance with the NHS Constitution. Somwaru LL, Arnold AM, Joshi N, et al. Possible indications for treating subclinical hypothyroidism include improvement in symptoms, prevention of overt hypothyroidism, and prevention of adverse events . Commissioners and/or providers have a responsibility to implement the recommendations, in their local context, in light of their duties to have due regard to the need to eliminate unlawful discrimination, advance equality of opportunity, and foster good relations. When exercising their judgement, health professionals are expected to take these recommendations fully into account, alongside the individual needs, preferences and values of their patients. The thyroid-related quality of life measure ThyPRO has good responsiveness and ability to detect relevant treatment effects. New clinical practice guidelines strongly recommend against the routine use of thyroid hormones in adults with subclinical hypothyroidism, based on a systematic review published in the BMJ.. Subclinical hypothyroidism is defined biochemically as elevated levels of thyroid-stimulating hormone with normal free thyroxine levels. Bekkering and colleages aim their attack “against thyroid hormones” in adults with Subclinical Hypothyroidism: “The guideline panel issues THYPRO) to assess outcome6.  Since TSH and FT4 levels may not reflect thyroid status of peripheral tissues, further work is needed to develop better markers of tissue hypothyroidism and include these in future trials. Pathway created: November 2019 Last updated: November 2020. J Clin Endocrinol Metab 2001; 86:4591. Consider referral to a specialist for further management options. This review of 21 trials only contained 2,192 participants of whom a significant number (737) were enrolled in what was originally a cardiovascular trial (TRUST) which focussed on older subjects (aged over 65 years) with many lacking thyroid symptoms at baseline. Together we aim to improve public health by advancing endocrine education and research, and engaging wider audiences with the science of hormones. www.endocrinology.org, Find out more about the British Thyroid Association at www.british-thyroid-association.orgÂ, Obesity is linked to heavy periods and impaired womb repair, New podcast series reveals the truth about hormones and health, Increased breast cancer risk in obesity linked to fat cell chemicals, Society for Endocrinology & British Thyroid Association issue statement against new treatment recommendations for subclinical hypothyroidism, Thyroid hormones treatment for subclinical hypothyroidism: a clinical practice guideline, Autism may be associated with a reduction in oxytocin, Sardines may reduce risk of type 2 diabetes, New androgen research may improve treatments for cancer, Diabetes medication may improve asthma symptoms. Guidelines from ATA and AACE suggest that individuals with SCHyper should be treated when serum TSH is <0.1 mIU/L in those aged ≥65 years with cardiac risk factors, heart disease, or osteoporosis; postmenopausal women who are not on estrogens or bisphosphonates; and in individuals with hyperthyroid symptoms (). However, the interactive flowchart does not override the individual responsibility of healthcare professionals to make decisions appropriate to the circumstances of the individual patient, in consultation with the patient and/or guardian or carer. Use of carbimazole is subject to MHRA advice on contraception (, At the time of publication (November 2019), carbimazole did not have a UK marketing authorisation for children under 2 years. Subclinical hyperthyroidism is a relatively common condition for which prospectively derived evidenced-based management guidelines do not exist. The recommendations in this interactive flowchart represent the view of NICE, arrived at after careful consideration of the evidence available. BMJ. adults with TSH levels above 10 mIU/L. Global epidemiology of hyperthyroidism and hypothyroidism. who experience adverse reactions to carbimazole, who are pregnant or trying to become pregnant within the following. 1.5.3 Consider levothyroxine for adults with subclinical hypothyroidism who have a TSH of 10 mlU/litre or higher on 2 separate occasions 3 months apart. Figures show that hormone treatment for subclinical hypothyroidism doubled from 1996 to 2006.2 Current guidelines tend to recommend thyroid hormones for adults with thyroid stimulating hormone (TSH) concentrations greater than 10 mIU/L and for people with lower concentrations who are young, show symptoms, or have specific indications for prescribing. 1          Bekkering, G. E. et al. Others report symptoms characteristic of hypothyroidism, including tiredness, weight gain, feeling the cold, muscle cramps and depression. The recommendations in this guideline represent the view of NICE, arrived at after careful consideration of the evidence available. 5 Draft for consultation, June 2019 This guideline covers assessing and managing thyroid disease. Treatment should be based on the underlying etiology of subclinical hyperthyroidism. An Online Survey of Hypothyroid Patients Demonstrates Prominent Dissatisfaction. The definition of subclinical hyperthyroidism (SHyper) is based exclusively on laboratory findings, not clinical criteria [1,2,3,4,5,6].SHyper is defined biochemically by a subnormal serum thyroid-stimulating hormone (TSH) level, with normal levels of free thyroxine (FT 4), triiodothyronine … The new BMJ guideline recommends a threshold for SCH treatment that SfE and BTA do not believe is supported by the data, and is far too stringent. Definition, Aetiology and Prevalence of Endogenous Subclinical Hyperthyroidism. 2019 ETA Guidelines on the Management of Thyroid Dysfunction following Immune Reconstitution Therapy. Informed consent should be obtained and documented. Each is satisfactory, but none is ideal. This review aims to investigate the relationship between SH and bone loss in terms of the gender-dependent effects of SH on BMD. The rapid communication, “Thyroid hormones treatment for subclinical hypothyroidism: a clinical practice guideline” was published in the British Medical Journal on 14 May 2019. Subclinical hypothyroidism guideline recommends against treatment. (4). Peter Taylor, clinical senior lecturer and consultant endocrinologist at Cardiff University said, “What this detailed summary of the data does show is the urgent need for clinical trials of symptomatic patients with subclinical hypothyroidism especially in younger individuals.”, Onyebuchi Okosieme, consultant endocrinologist at Cardiff University School of Medicine said, “It is difficult to justify denying treatment to patients with fairly advanced degrees of subclinical hypothyroidism (TSH levels of 10-20 mU/L), as recommended by these guidelines. People have the right to be involved in discussions and make informed decisions about their care, as described in. This NICE Pathway covers investigating all suspected thyroid disease and managing primary thyroid disease (related to the thyroid rather than the pituitary gland). Hypothyroidism is usually treated by taking daily hormone replacement tablets; however, there is some debate on the appropriate hormone level thresholds that should be used for diagnosis and treatment of SCH. Thyroid hormones treatment for subclinical hypothyroidism: a clinical practice guideline. For those with lower TSH levels, most guidelines recommend treatment only when people are younger, symptomatic, or have other indications for prescribing (such as cardiovascular disease or antibodies to thyroid peroxidase). J … This clinical practice guideline which looked at thyroid hormone treatment in subclinical hypothyroidism summarises the evidence very well, but we are most concerned about the recommendations … They should do so in the context of local and national priorities for funding and developing services, and in light of their duties to have due regard to the need to eliminate unlawful discrimination, to advance equality of opportunity and to reduce health inequalities. Guidelines generally recommend thyroid hormones for . The 2015 European Thyroid Association guidelines on diagnosis and treatment of endogenous subclinical hyperthyroidism. Current Opinion in Endocrinology, Diabetes and Obesity, doi:10.1097/med.0000000000000180 (2015), 6          Watt, T. et al. SfE and BTA are concerned that these recommendations could influence primary care physicians to dismiss patients with subclinical hypothyroidism, particularly younger ones, which could lead to some missing out on vital treatment if their condition progresses. In this review the prevalence of low TSH in the population and health consequences of subclinical hyperthyroidism, for example, effects on heart and bone mass, are discussed. This narrative review aims to assess current evidence on the clinical aspects, as well as screening and treatment recommendations in adults with subclinical hypothyroidism. Nothing in this guideline should be interpreted in a way that would be inconsistent with complying with those duties. Furthermore, with the degree of TSH elevations in the studies contained in this meta-analysis being modest, we contend that their recommendations based on a TSH cut off of >20 mIU/l go beyond the scope of the available primary data. The prescriber should follow relevant professional guidance, taking full responsibility for the decision. Biondi B, Bartalena L, Cooper DS, Hegedus L, Laurberg P, Kahaly GJ. As outlined in the SfE and BTA statement, both disagree with the strong conclusion: “The panel concluded that almost all adults with SCH would not benefit from treatment with thyroid hormones.”. https://doi.org/10.1159/000500881. Neonatal infection: antibiotics for prevention and treatment Prophylaxis against infective endocarditis Self-limiting respiratory tract and ear infections – antibiotic prescribing Bacterial meningitis and meningococcal septicaemia in under 16s Hepatitis. Thus, the remainder of the meta-analysis is based on predominantly small-scale trials. Before starting antithyroid drugs for adults, children and young people with hyperthyroidism, check full blood count and liver function tests. The Society for Endocrinology is a UK-based membership organisation representing a global community of scientists, clinicians and nurses who work with hormones. The rapid communication, “Thyroid hormones treatment for subclinical hypothyroidism: a clinical practice guideline ” was published in the British Medical Journal on 14 May 2019. Subject to Notice of rights. Currently, the best practical approach is to base treatment decisions on the degree of TSH elevation, thyroid autoimmunity, and associated comorbidities.
