50 recommendations that form these guidelines

Number Recommendation Strength and level of evidence
1 The measurement of TSH-R-Ab is a sensitive and specific tool for rapid and accurate diagnosis and differential diagnosis of Graves' hyperthyroidism 1, ØØØØ

2 When technically available, differentiation of TSH-R-Ab functionality is helpful and predictive in Graves' patients during pregnancy/post-partum, as well as for extra-thyroidal manifestations 2, ØØØO

3 US examination, comprising conventional grey scale analysis and color-flow or power Doppler examination is recommended as the imaging procedure to support the diagnosis of Graves' hyperthyroidism 1, ØØØØ

4 Scintigraphy of the thyroid is suggested when thyroid nodularity coexists with hyperthyroidism, and prior to radioactive iodine therapy 2, ØØØO

5 Patients with newly diagnosed Graves' hyperthyroidism should be treated with ATD. RAI therapy or thyroidectomy may be considered in patients who prefer this approach 1, ØØØØ

6 MMI (CBZ) should be used in every non-pregnant patient who chooses ATD therapy for Graves' hyperthyroidism 1, ØØØØ

7 MMI is administered for 12–18 months then discontinued if the TSH and TSH-R-Ab levels are normal 1, ØØØØ

8 Measurement of TSH-R-Ab levels prior to stopping ATD therapy is recommended, as it aids in predicting which patients can be weaned from the medication, with normal levels indicating a greater chance of remission 1, ØØØØ

9 Patients with persistently high TSH-R-Ab at 12–18 months can continue MMI therapy, repeating the TSH-R-Ab measurement an after additional 12 months, or opt for RAI or thyroidectomy 1, ØØØO

10 Patients should be informed of potential side effects of ATD and the necessity of informing the physician promptly if they should develop jaundice, light-colored stools, dark urine, fever, pharyngitis, or cystitis 1, ØØOO

11 In patients taking ATD, a differential white blood cell count should be obtained during febrile illness and/or pharyngitis, and liver function should be assessed in those who experience jaundice, light-colored stools, or dark urine 1, ØØOO

12 Beta-adrenergic blockade is recommended in all suitable patients with Graves' hyperthyroidism 1, ØØØØ

13 If a patient with GD becomes hyperthyroid after completing a first course of ATD, definitive treatment with RAI or thyroidectomy is recommended. Continued long-term low-dose MMI can be considered in patients not in remission who prefer this approach 1, ØØØO

14 Treatment of SH is recommended in Graves' patients 7gt;65 years with serum TSH levels that are persistently <0.1 mIU/L 1, ØØOO

15 ATD should be the first choice of treatment of Graves' SH 1, ØØOO

16 A multimodality treatment approach to GD patients with thyroid storm should be used, including ATD therapy, glucocorticoid administration, beta-adrenergic blockade, cooling blankets, volume resuscitation, nutritional support, respiratory care, and monitoring in an intensive care unit 1, ØØOO

17 There are no absolute indications for RAI therapy, but it is often recommended for patients with side-effects to, or recurrence after a course of ATD 1, ØØOO

18 Verbal as well as written information on all aspects of efficacy and potential side-effects of RAI therapy should be provided 1, ØØOO

19 If ATD are used before RAI therapy they should be paused around 1 week before and after therapy in order not to decrease the efficacy of RAI 1, ØØØØ

20 No dose calculation can secure long-term euthyroidism and it is fully acceptable to offer a fixed dose of RAI 1, ØØØO

21 Pregnancy and breast feeding constitute absolute contraindications to RAI therapy 1, ØØØO

22 Conception should be postponed until at least 6 months after RAI in both males and females 1, ØØØO

23 If used in children, ablative doses aiming at rapid hypothyroidism should be administered 1, ØØOO

24 If surgery is selected, total thyroidectomy is the procedure of choice, and should be performed by a skilled surgeon with high annual volumes of thyroidectomies 1, ØØØØ

25 Euthyroidism should be restored by ATD prior to surgery to avoid peri- or postoperative exacerbation of thyrotoxicosis 1, ØØØØ

26 Vitamin D deficiency should be corrected to reduce the postoperative risk of hypocalcemia 1, ØØØØ

27 A solution containing potassium iodide can be given for 10 days prior to surgery 2, ØØØO

28 In patients with GO, hyperthyroidism should be promptly controlled by ATD, and euthyroidism stably maintained 1, ØØØØ

29 Patients treated with RAI should receive steroid prophylaxis if mild and active GO preexists or there are risk factors for RAI-associated GO occurrence or progression 1, ØØØØ

30 In patients with moderate-to-severe and active GO, treatment of GO should be the priority. Euthyroidism should be promptly restored with ATD and stably maintained 1, ØØØØ

31 Patients with sight-threatening GO should be treated with ATD 1, ØØOO

32 Treatment for hyperthyroidism in patients with inactive GO can be selected independently of GO 1, ØØOO

33 Women with GD of reproductive age should be offered preconception counseling and be stably euthyroid before attempting pregnancy 1, ØØOO

34 Women with GD should be instructed to immediately confirm pregnancy and contact their physician 1, ØØØØ

35 Women treated with MMI should be switched to PTU when planning pregnancy and/or during the first trimester of pregnancy 1, ØØØØ

36 All patients with a history of autoimmune thyroid disease should have their TSH-R-Ab serum levels measured at the first presentation of pregnancy using either a sensitive binding or a functional cell-based bioassay and, if they are elevated, again at 18–22 weeks of gestation 1, ØØØØ

37 If the maternal TSH-R-Ab concentration remains high (>3 times the cut-off), monitoring of the fetus for thyroid dysfunction throughout pregnancy is recommended 1, ØØØØ

38 During pregnancy the lowest possible dose of ATD should be given and the block-and-replace ATD regimen is discouraged 1, ØØØØ

39 Maternal FT4 (TT4) and TSH should be measured every 2 weeks after initiation of therapy, and every 4 weeks after achieving the target value 1, ØØOO

40 A change from PTU to MMI should be considered if ATD are required after 16 weeks gestation 1, ØOOO

41 In women on a low dose of MMI (<5–10 mg/day) or PTU (<50–100 mg/day), ATD may be stopped during gestation prior to weeks 6–10 2, ØOOO

42 Lactating women with GD should be offered the same treatments as non-lactating women 1, ØØOO

43 MMI is recommended during lactation, given the concerns about PTU-mediated hepatotoxicity 1, ØØOO

44 Older patients who have had atrial fibrillation, cardiac failure, or cardiac ischemic symptoms precipitated by hyperthyroidism should undergo definitive therapy, usually RAI 1, ØØØO

45 Long-term MMI (CBZ) should be considered as a satisfactory treatment for older individuals with mild GD 2, ØOOO

46 PTU should be avoided in children and adolescents 1, ØØØØ

47 Long-term MMI (CBZ) should be the mainstay of treatment in children with GD 1, ØØØØO

48 Thyroidectomy is the primary definitive therapy in childhood, but in post-pubertal children RAI can be considered 2, ØØOO

49 Graves' hyperthyroidism precipitated by an immunomodulatory therapy is not a mandatory indication to stop that precipitating treatment, nor is it a mandatory indication for definitive therapy for hyperthyroidism 1, ØOOO

50 Sequential monitoring of serum TSH-R-Ab levels can be used to guide the duration of ATD therapy in patients with immune reconstitution GD 2, ØOOO
