Abstract: Graves' disease is a common autoimmune disorder in women in fertile ages. The hyperthyroidism is caused by generation of TSH-receptor activating antibodies. In pregnancy both the antibodies and the antithyroid medication given to the mother pass the placenta and affect the foetal thyroid gland. Thyroid function should be controlled not only in the mother with Graves' hyperthyroidism but also in her foetus.The review includes two cases illustrating some of the problems in managing Graves' disease in pregnancy. Major threats to optimal foetal thyroid function are inadequate or over aggressive antithyroid drug therapy of the mother. It should be taken into account that antithyroid drugs tend to block the foetal thyroid function more effectively than the maternal thyroid function, and that levothyroxin (L-T(4)) given to the mother will have only a limited effect in the foetus. Surgical thyroidectomy of patients with Graves' hyperthyroidism does not lead to immediate remission of the autoimmune abnormality, and the combination thyroidectomy+withdrawal of antithyroid medication+L-T(4) replacement of the mother involves a high risk of foetal hyperthyroidism. Conclusion Antithyroid drug therapy of pregnant women with Graves' hyperthyroidism should be balanced to control both maternal and foetal thyroid function. Surgical thyroidectomy of a pregnant woman with active disease may lead to isolated foetal hyperthyroidism.

Abstract: Mild forms of hypothyroidism--subclinical hypothyroidism--have recently been discussed as being a risk factor for the development of overt thyroid dysfunction and for a number of clinical disorders. The diagnosis critically depends on the definition of the upper normal limit of serum TSH as, by definition, free thyroxine serum concentrations are normal. Cut-off levels of 4-5 mU TSH/l have been conventionally used to diagnose an elevated TSH serum concentration. Recent data from large population studies have suggested a much lower TSH cut-off with an upper limit of 2-2.5 mU/l but application of strict criteria for inclusion of subjects from the general population studies aiming at assessing TSH reference intervals (no personal or family history of thyroid disease, no thyroid antibodies and a normal thyroid on ultrasonography) did not result in an unequivocal upper limit of normal TSH at 2.0-2.5 mU/l. When summarizing the available evidence for lowered upper TSH cut-off values and their potential therapeutic implications there is presently insufficient justification to lower the upper normal limit of TSH and, for practical purposes, it is still recommended to maintain the TSH reference interval of 0.4-4.0 mU/l. Classifying subjects with a TSH value between 2 and 4 mU/l as abnormal, as well as intervening with thyroxine treatment in such subjects, is probably doing more harm than good.

Abstract: The various aspects of primary thyroid insufficiency are presented. Subclinical hypothyroidism is a special condition the prevalence of which is increasing. In the face of a growing concern of the population, subclinical hypothyroidism receives much attention from endocrinologists and internists but despite recent recommendations therapeutic strategies are not clear enough yet. The question of the feasibility of the systematic screening, at least in predisposed people, for hypothyroidism is under study. Overt hypothyroidism which is usually preceded by a long phase of subclinical hypothyroidism is therefore presentable if substitutive treatment is given early enough. Occasional patients, however, may rich the level of profound hypothyroidism unnoticed. The modalities of treatment of over hypothyroidism are described. Latrogenic hypothyroidism is also described. Finally, myxoedema coma is discussed not because its prevalence, which is very low, but because this condition may be forgotten.

Abstract: First cause of hyperthyroidism among women of childbearing age, Graves' disease raises the risk of maternal and fetal complications, including eclampsia, cardiac failure, abortion, prematurity, fetal death, all of which can be avoided if maternal hyperthyroidism is closely controlled. The risk of transplacental hyperthyroidism has been shown to correlate to the titre of anti-TSH receptor antibodies and has to be evaluated not only in women treated for Graves' disease during pregnancy, but also in women who have previously received radio iodine treatment or undergone surgery for Graves' disease: TSH-receptor antibodies may indeed remain at a high level several years after initial treatment. Both methimazole and propylthiouracil are equally effective to restore maternal euthyroidism. Accumulation of case-reports relating congenital malformations (mostly aplasia cutis, but in some cases, severe malformations) among the offspring of methimazole-treated women suggests the possibility of a teratogenic effect of methimazole. Despite the fact that the link between severe congenital defects and methimazole exposure during pregnancy is not formally established, propylthiouracil should be preferred to methimazole for the treatment of young hyperthyroid women.

Abstract: It has been a continuing challenge to try and identify those patients with hyperthyroid Graves' disease likely to remain in remission after an antithyroid drug course or to manage the medical treatment so as to increase the chance of remission. On average, the overall relapse rate is approximately 50% and any significant reduction of this figure would be of practical as well as theoretical value. The numerous controlled prospective studies performed in many parts of the world, with varying iodine intakes, have all confirmed that the main initial features related to the subsequent risk of relapse are: young age, male gender, goiter larger than 40 mL, hypoechogenic and hypervascular gland, high level of anti-thyrotropin receptor antibody (TRAb), detected either with radioreceptor assay (TBII: >40 U/L) or the biologic stimulation assay (thyroid-stimulating antibodies [TSAb]; >300%), severity of hyperthyroidism, and possibly the presence of ophthalmopathy. Alone, each of these has a low predictive value, but together they allow evaluation of the risk of relapse, thus helping treatment choice. As to the modalities of antithyroid drug treatment, dose of the drug or addition of levothyroxine does not affect posttreatment outcome. In contrast, significantly fewer relapses occur for drug courses longer than at least 1 year. Persistence of high levels of TRAb after medical treatment is strongly predictive of relapse but this is of limited value because in most patients, TRAb levels are low or even undetectable at the end of treatment, which does not indicate for further outcome. Smoking is a significant independent risk factor for relapse. In conclusion, reduction of the risk of relapse in patients with medically treated hyperthyroid Graves' disease relies on clinical competence and appropriate management taking into account an array of factors none of which alone has definite predictive value.

Abstract: Anti-thyroid stimulating hormone receptor antibodies are pathophysiologic and clinical indicators in autoimmune thyroid diseases, not only in Graves' disease. The detection of these antibodies is useful for diagnostic and management purposes. The presence and titers of anti-TSH receptor antibodies, however, have to be interpreted in light of the clinical and other biological characteristics of each patient. Newer, more sensitive assays of anti-TSH receptor antibodies may increase their significance in the diagnosis and management of autoimmune thyroid diseases and Graves' disease.

Abstract: Despite its high prevalence, at least in areas with even mild iodine deficiency, the aetiopathogenesis of multinodular goitre is poorly understood. The combination of genetic and environmental factors, the likely involvement of endocrine para and autocrine goitrogenic agents and the remarkable heterogenicity of thyroid tissue complicate elucidation of the mechanisms involved. Multinodular goitre follows an initial phase of hyperplastic goitre or results from the generation of several individual nodules. Alterations of the stromal and vascular tissues as well as the occurrence of somatic mutations are contributing factors. In many instances, multinodular goitres become autonomous in the long term.

Abstract: There are few effective, safe modalities for the management of Graves' ophthalmopathy (GO), a cell-mediated immune comorbidity of thyroid disease. Somatostatin analogs inhibit lymphocyte proliferation and activation, and accumulate in the orbital tissue of patients with GO. A double-blind, placebo-controlled study of a long-acting somatostatin analog [16 wk of long-acting release formulation of octreotide (octreotide-LAR)] was conducted in 51 patients with mild active GO with the aim of preventing deterioration and precluding the need for more aggressive therapeutic modalities, such as glucocorticoids or radiotherapy. No treatment effect was observed for the primary end point (a composite parameter defining the outcome as either success or failure on the basis of changes in class/grade of the severity index and Clinical Activity Scale of GO). The Clinical Activity Scale score was reduced for patients treated with octreotide-LAR, but without any significant difference with respect to patients receiving placebo. However, octreotide-LAR significantly reduced proptosis (as measured by exophthalmometry). This was associated with nonsignificant differences in favor of octreotide-LAR in a series of proptosis-related parameters: class III grade, opening of the upper eyelid, the difference in ocular pressure between primary position and upgaze, and extraocular muscle involvement. By magnetic resonance imaging evaluation the extraocular muscle volumes appeared reduced, but nonsignificantly. No significant correlation between the initial uptake of the somatostatin analog indium-labeled and the response to treatment was observed. One patient in the octreotide-LAR group developed gallstones. In this study, octreotide-LAR did not seem suitable to mitigate activity in mild GO. Surprisingly, it significantly reduced proptosis, one of the most debilitating symptoms of GO. Additional studies are warranted to define the benefit to risk ratio of the somatostatin analogs in this indication.

Abstract: The efficacy of suppressing TSH secretion with levothyroxine (L-T(4)) in reducing solitary thyroid nodule growth is still controversial. In this prospective multicenter, randomized, double-blind, placebo-controlled trial, 123 patients with a single palpable benign nodule were included and randomly allocated to an 18-month treatment with L-T(4) or placebo. Individual dose was adjusted to allow a serum TSH level below 0.3 mIU/liter. Clinical and ultrasonographic nodule characteristics were assessed before treatment and 3, 6, 12, and 18 months thereafter. The largest mean nodule size assessed on palpation and largest volume, assessed by ultrasonography, decreased in the L-T(4) group and increased slightly in the placebo group [size, -3.5 +/- 7 mm vs. +0.5 +/- 6 mm (P = 0.006); volume, -0.36 +/- 1.71 ml vs. +0.62 +/- 3.67 ml (P = 0.01), respectively]. The proportion of clinically relevant volume reduction (> or =50%) rose significantly in the L-T(4) group [26.6% vs. 16.9% (P = 0.04)]. The proportion of patients with a reduced number of infraclinical additional nodules was significantly higher in the L-T(4) group [9.4% vs. 0 (P = 0.04)]. It is concluded from this study that suppressive L-T(4) therapy is effective in reducing solitary thyroid nodule volume and improving infraclinical extranodular changes.

Abstract: OBJECTIVE: The aim of the present study was to determine recent trends in thyroid cancer incidence rates and to analyze histopathological characteristics and geographical distribution. METHODS: Histologically proven 5367 cases were collected over the period 1998-2006 in France from the Rhône-Alpes thyroid cancer registry. Geographical variations of incidence were analyzed using a mixed Poisson model. RESULTS: The average incidence rates, age standardized to the world population, were 3.9/100,000 in men and 12.3/100,000 in women, higher than those previously reported in France. After an initial increase during the first 3 years, a steady level of incidence was observed for the period 2001-2006. The annual incidence rate of microcarcinomas was correlated with that of all cancers in men and women (r=0.78 and 0.89; P<0.01) respectively. Papillary microcarcinomas represented 38% of tumors and two-thirds of them measured less than 5 mm in diameter. They were fortuitously discovered after thyroidectomy for benign diseases in 64% of cases. Histological marks of aggressiveness differed according to the size of the tumor. Despite recent advances in diagnosis, 13% of tumors were diagnosed at advanced stage especially in men. Geographical distribution of incidence based on subregional administrative entities showed lower incidence rates in rural than in urban zones in men (relative rate: 0.72; 95% CI: 0.62-0.84) and women (relative rate: 0.85; 95% CI: 0.73-0.93). CONCLUSION: The present study suggests that the rise in thyroid cancer incidence is now abating. It could reflect standardization in diagnostic procedures. Further studies, performed on a more prolonged period, are necessary to confirm these data.

Abstract: We report here the 20-year follow-up study of a male subject diagnosed at 15 months of age as a sporadic case of pituitary resistance to thyroid hormone on the combination of clinical hyperthyroidism, elevated serum thyroid hormone (TH) levels and inappropriate thyrotropin (TSH). On D-thyroxine (D-T(4)) therapy from 30 months of age to 12.5 years, hyperactivity and hyperthyroid signs and symptoms as well as growth abnormalities improved, serum L-thyroxine (L-T(4)) enantiomer normalized, and basal and stimulated TSH decreased significantly without complete suppression. After 8 years off D-T(4), at 20 years of age, clinical status was normal despite persisting high TH levels and inappropriate TSH. Evolution of serum markers of TH action and echocardiography measurements followed up from 15 months to 20 years of age either in basal condition or on triiodothyronine (T(3)), as well as the sequential determination of bone mineral density suggest differences in the tissue responses to T(3): normal in bone with a high remodelling rate, heterogeneity for various hepatic markers, and decreased at heart level. No mutations were found in the coding sequence of TRbeta1, TRbeta2, TRalpha1, RXRgamma, SMRT, NCoR1, and NCoA1. In this patient the putative long-term effects of the persisting high bone resorption are unknown.

Abstract: CONTEXT: Detection of thyroid cancer among benign nodules on fine-needle aspiration biopsies (FNAB), which presently relies on cytological examination, is expected to be improved by new diagnostic tests set up from genomic data. OBJECTIVE: The aim of the study was to use a set of genes discriminating benign from malignant tumors, on the basis of their expression levels, to build tumor classifiers and evaluate their capacity to predict malignancy on FNAB. DESIGN: We analyzed the level of expression of 200 potentially informative genes in 56 thyroid tissue samples (benign or malignant tumors and paired normal tissue) using nylon macroarrays. Gene expression data were subjected to a weighted voting algorithm to generate tumor classifiers. The performances of the classifiers were evaluated on a series of 26 sham FNAB, i.e. FNAB carried out on thyroid nodules after surgical resection. RESULTS: A series of 19 genes with a similar expression in follicular adenomas and normal tissue and discriminating follicular adenomas+normal tissue from the following: 1) follicular thyroid carcinomas (FTCs), 2) papillary thyroid carcinomas (PTCs), or 3) both FTCs and PTCs. These were used to generate four classifiers, the FTCs, PTCs, common (FTC+PTCs), and global classifiers. In 23 of the 26 sham FNAB, the four classifiers yielded a diagnosis in agreement with the diagnosis of the pathologist used as reference; in the three other cases, the correct diagnosis was given by three of four classifiers. CONCLUSIONS: We developed a procedure of molecular diagnosis of benign vs. malignant tumors applicable to the material collected by FNAB. The molecular test complied with a preclinical validation stage; it must be now evaluated on ultrasound-guided FNAB in a large-scale prospective study.

Abstract: Iodine intake varies with age and physiological status: in pregnant and lactating women, recommended iodine intake ranges from 200 to 250 mg/day. Recent epidemiological studies in France demonstrate the presence of moderate iodine deficiency in the majority of pregnant and lactating women. This iodine deficiency induces maternal thyroid hyperplasia and then development of goiter in women, as well as impaired thyroid parameters. Maternal hypothyroxinemia during the first trimester of pregnancy can be associated with abnormal cognitive development and intellectual outcomes in the newborn and the children. According to the recent World Health Organization recommendations for the prevention and control of iodine deficiency in pregnant and lactating women, systematic iodine supplementation is indicated in France: 100 microg/day for women of reproductive age and 200 microg/day in pregnant and lactating women in order to eradicate iodine deficiency during pregnancy and lactation, and prevent the maternal and fetal consequences.

Abstract: 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.

Abstract: OBJECTIVE: To determine management patterns among clinicians who treat patients with Graves' orbitopathy (GO) in Europe. DESIGN AND METHODS: Questionnaire survey including a case scenario of members of professional organisations representing endocrinologists, ophthalmologists and nuclear medicine physicians. RESULTS: A multidisciplinary approach to manage GO was valued by 96.3% of responders, although 31.5% did not participate or refer to a multidisciplinary team and 21.5% of patients with GO treated by responders were not managed in a multidisciplinary setting. Access to surgery for sight-threatening GO was available only within weeks or months according to 59.5% of responders. Reluctance to refer urgently to an ophthalmologist was noted by 32.7% of responders despite the presence of suspected optic neuropathy. The use of steroids was not influenced by the age of the patient, but fewer responders chose to use steroids in a diabetic patient (72.1 vs 90.5%, P<0.001). Development of cushingoid features resulted in a reduction in steroid use (90.5 vs 36.5%, P<0.001) and increase in the use of orbital irradiation (from 23.8% to 40.4%, P<0.05) and surgical decompression (from 20.9 to 52.9%, P<0.001). More ophthalmologists chose surgical decompression for patients with threatened vision due to optic neuropathy, who were intolerant to steroids than other specialists (70.3 vs 41.8%, P<0.01). CONCLUSION: Deficiencies in the management of patients with GO in Europe were identified by this survey. Further training of clinicians, easier access of patients to specialist multidisciplinary centres and the publication of practice guidelines may help improve the management of this condition in Europe.
