Consensus statement of the European Group on Graves' orbitopathy (EUGOGO) on management of GO

Summary of consensus a. All patients with GO should (Fig. 1):Be referred to specialist centers;Be encouraged to quit smoking;Receive prompt treatment in order to restore andmaintain euthyroidism.b. Patients with sight-threatening GO should be treatedwith i.v. GCs as the first-line treatment; if the responseis poor after 1–2 weeks, they should be submitted tourgent surgical decompression.c. The treatment of choice for moderate-to-severe GO isi.v. GCs (with or without OR) if the orbitopathy isactive;surgery(orbitaldecompression,squintsurgery,and/or eyelid surgery in this order) should beconsidered if the orbitopathy is inactive.d. In patients with mild GO, local measures and anexpectant strategy are sufficient in most cases, buttreatment may be justified if QoL is affectedsignificantly. In memoriam This document is dedicated to the memory of MarkPrummel (1956–2005), one of the founders ofEUGOGO, who greatly contributed to expanding ourunderstanding of clinical and therapeutic aspects of GO.

Clinical Features of Dysthyroid Optic Neuropathy: A European Group on Graves Orbitopathy (EUGOGO) Survey

Background: This study was performed to determine clinical features of dysthyroid optic neuropathy (DON) across Europe. Methods: Forty seven patients with DON presented to seven European centres during one year. Local protocols for thyroid status, ophthalmic examination and further investigation were used. Each eye was classified as having definite, equivocal, or no DON. Results: Graves’ hyperthyroidism occurred in the majority; 20% had received radioiodine. Of 94 eyes, 55 had definite and 17 equivocal DON. Median Clinical Activity Score was 4/7 but 25% scored 3 or less, indicating severe inflammation was not essential. Best corrected visual acuity was 6/9 (Snellen) or worse in 75% of DON eyes. Colour vision was reduced in 33 eyes, of which all but one had DON. Half of the DON eyes had normal optic disc appearance. In DON eyes proptosis was > 21 mm (significant) in 66% and visual fields abnormal in 71%. Orbital imaging showed apical muscle crowding in 88% of DON patients. Optic nerve stretch and fat prolapse were infrequently reported. Conclusion: Patients with DON may not have severe proptosis and orbital inflammation. Optic disc swelling, impaired colour vision and radiological evidence of apical optic nerve compression are the most useful clinical features in this series.

Cinacalcet Reduces Serum Calcium Concentrations in Patients with Intractable Primary Hyperparathyroidism

CONTEXTnPatients with persistent primary hyperparathyroidism (PHPT) after parathyroidectomy or with contraindications to parathyroidectomy often require chronic treatment for hypercalcemia.nnnOBJECTIVEnThe objective of the study was to assess the ability of the calcimimetic, cinacalcet, to reduce serum calcium in patients with intractable PHPT.nnnDESIGNnThis was an open-label, single-arm study comprising a titration phase of variable duration (2-16 wk) and a maintenance phase of up to 136 wk.nnnSETTINGnThe study was conducted at 23 centers in Europe, the United States, and Canada.nnnPATIENTSnThe study included 17 patients with intractable PHPT and serum calcium greater than 12.5 mg/dl (3.1 mmol/liter).nnnINTERVENTIONnDuring the titration phase, cinacalcet dosages were titrated every 2 wk (30 mg twice daily to 90 mg four times daily) for 16 wk until serum calcium was 10 mg/dl or less (2.5 mmol/liter). If serum calcium increased during the maintenance phase, additional increases in the cinacalcet dose were permitted.nnnMAIN OUTCOME MEASUREnThe primary end point was the proportion of patients experiencing a reduction in serum calcium of 1 mg/dl or greater (0.25 mmol/liter) at the end of the titration phase.nnnRESULTSnMean +/- sd baseline serum calcium was 12.7 +/- 0.8 mg/dl (3.2 +/- 0.2 mmol/liter). At the end of titration, a 1 mg/dl or greater reduction in serum calcium was achieved in 15 patients (88%). Fifteen patients (88%) experienced treatment-related adverse events, none of which were serious. The most common adverse events were nausea, vomiting, and paresthesias.nnnCONCLUSIONSnIn patients with intractable PHPT, cinacalcet reduces serum calcium, is generally well tolerated, and has the potential to fulfill an unmet medical need.

Outcome of orbital decompression for disfiguring proptosis in patients with Graves' orbitopathy using various surgical procedures

Aim: To compare the outcome of various surgical approaches of orbital decompression in patients with Graves’ orbitopathy (GO) receiving surgery for disfiguring proptosis. Method: Data forms and questionnaires from consecutive, euthyroid patients with inactive GO who had undergone orbital decompression for disfiguring proptosis in 11 European centres were analysed. Results: Eighteen different (combinations of) approaches were used, the swinging eyelid approach being the most popular followed by the coronal and transconjunctival approaches. The average proptosis reduction for all decompressions was 5.0 (SD 2.1) mm. After three-wall decompression the proptosis reduction was significantly greater than after two-wall decompression. Additional fat removal resulted in greater proptosis reduction. Complications were rare, the most frequent being worsening of motility, occurring more frequently after coronal decompression. The average change in quality of life (QOL) in the appearance arm of the GO-QOL questionnaire was 20.5 (SD 24.8) points. Conclusions: In Europe, a wide range of surgical approaches is used to reduce disfiguring proptosis in patients with GO. The extent of proptosis reduction depends on the number of walls removed and whether or not fat is removed. Serious complications are infrequent. Worsening of ocular motility is still a major complication, but was rare in this series after the swinging eyelid approach.

Treatment of adult Graves’ disease

Treatment strategy in Graves disease firstly requires recovery of euthyroid status by antithyroid therapy. Treatment modalities, precautions, advantages and side-effects are to be discussed with the patient. No particular treatment modality has demonstrated superiority. Pregnancy or pregnancy project affects choice of treatment and monitoring. Graves orbitopathy is liable to be aggravated by iodine-131 treatment and requires pre-treatment assessment. Iodine-131 treatment aims at achieving hypothyroidism. Thyroid surgery for Graves disease should preferably be performed by an expert team. In case of recurrence of hyperthyroidism, the various treatment options should be discussed with the patient. Empiric treatment of thyroid dermopathy uses local corticosteroids in occlusive dressing.
