RESUMEN

PURPOSE: The use of thyroid hormones (TH) to treat obesity is unsupported by evidence as reflected in international guidelines. We explored views about this practice, and associations with respondent characteristics among European thyroid specialists. METHODS: Specialists from 28 countries were invited to a survey via professional organisations. The relevant question was whether "Thyroid hormones may be indicated in biochemically euthyroid patients with obesity resistant to lifestyle interventions". RESULTS: Of 17,232 invitations 5695 responses were received (33% valid response rate; 65% women; 90% endocrinologists). Of these, 290 (5.1%) stated that TH may be indicated as treatment for obesity in euthyroid patients. This view was commoner among non-endocrinologists (8.7% vs. 4.7%, p < 0.01), private practice (6.5% vs. 4.5%, p < 0.01), and varied geographically (Eastern Europe, 7.3%; Southern Europe, 4.8%; Western Europe, 2.7%; and Northern Europe, 2.5%). Respondents from Northern and Western Europe were less likely to use TH than those from Eastern Europe (p < 0.01). Gross national income (GNI) correlated inversely with this view (OR 0.97, CI: 0.96-0.97; p < 0.001). Having national guidelines on hypothyroidism correlated negatively with treating obesity with TH (OR 0.71, CI: 0.55-0.91). CONCLUSIONS: Despite the lack of evidence, and contrary to guidelines' recommendations, about 5% of respondents stated that TH may be indicated as a treatment for obesity in euthyroid patients resistant to life-style interventions. This opinion was associated with (i) respondent characteristics: being non-endocrinologist, working in private practice, treating a small number of hypothyroid patients annually and (ii) national characteristics: prevalence of obesity, Eastern Europe, low GNI and lack of national hypothyroidism guidelines.

RESUMEN

PURPOSE: Whereas antithyroid drugs (ATD) are the preferred treatment modality for Graves' hyperthyroidism (GH), there is still controversy about the optimal regimen for delivering ATD. To evaluate whether 'Block and Replace' (B + R) and 'Titration' (T) regimes are equivalent in terms of frequency of euthyroidism and Graves' Orbitopathy (GO) during ATD therapy. METHODS: A prospective multicentre observational cohort study of 344 patients with GH but no GO at baseline. Patients were treated with ATD for 18 months according to B + R or T regimen in line with their institution's policy. RESULTS: Baseline characteristics were similar in both groups. In the treatment period between 6 and 18 months thyrotropin (TSH) slightly increased in both groups, but TSH was on average 0.59 mU/L (95% CI 0.27-0.85) lower in the B + R group at all time points (p = 0.026). Serum free thyroxine (FT4) remained stable during the same interval, with a tendency to higher values in the B + R group. The point-prevalence of euthyroidism (TSH and FT4 within their reference ranges) increased with longer duration of ATD in both groups; it was always higher in the T group than in the B + R group: 48 and 24%, respectively, at 6 months, 81 and 58% at 12 months, and 87 and 63% at 18 months (p < 0.002). There were no significant differences between the B + R and T regimens with respect to the fall in thyrotropin binding inhibiting immunoglobulins (TBII) or thyroid peroxidase antibodies (TPO-Ab). GO developed in 15.9% of all patients: 9.1 and 17.8% in B + R group and T group, respectively, (p = 0.096). GO was mild in 13% and moderate-to-severe in 2%. CONCLUSION: The prevalence of biochemical euthyroidism during treatment with antithyroid drugs is higher during T compared to B + R regimen. De novo development of GO did not differ significantly between the two regimens, although it tended to be higher in the T group. Whether one regimen is clinically more advantageous than the other remains unclear.

RESUMEN

PURPOSE: Recent work supports the use of T2-weighted MRI intensity as a tool for treatment stratification in acromegaly. Our study aimed to establish if the pattern of T2 intensity could be a predictor of hormonal and/or tumoral response to dopamine agonists (DAs) in prolactinomas. METHODS: This was a retrospective study performed in two academic centers. We characterized the magnetic resonance T2-weighted aspect of prolactinomas (signal intensity and homogeneity in the whole tumors) before DA therapy and correlated this pattern to the prolactin (PRL) concentration at diagnosis and to hormonal and tumoral responses after 1 year of medical treatment. We separately analyzed a subgroup of prolactinomas visually very bright in more than 50% of the surface ("cystic" tumors). RESULTS: Out of 70 prolactinomas, 80% were T2 hyperintense and 40% were heterogeneous. At diagnosis, heterogeneous prolactinomas were more frequent in men (68% vs. 28.9%, p ≤ 0.011), larger (median area 304.5 mm2 vs. 56.5 mm2, p ≤ 0.021), taller (mean height 18.6 mm vs. 9.9 mm, p < 0.001), more secreting (median PRL ULN_area 23 µg/L/cm2 vs. 12.6 µg/L/cm2, p ≤ 0.032) and had poorer hormonal response to DA as compared with homogeneous prolactinomas. "Cystic" tumors were diagnosed almost exclusively in women and secreted less prolactin, but showed similar hormonal and tumoral response as "non-cystic" tumors. In homogeneous prolactinomas, the T2-weighted intensity ratio was correlated to prolactin secretion, although not significantly, and did not predict hormonal and tumoral response to DA. CONCLUSIONS: Our study confirms that hypo/isointense prolactinoma is a rare finding and suggests for the first time that the heterogeneity of prolactinoma T2 signal at diagnosis might be correlated with a different clinical behavior and could be used as a negative predictor factor of hormonal response to DA.

RESUMEN

The syndrome of Familial Non Medullary Thyroid Carcinoma (FNMTC) includes two or more patients with an isolated non-medullary thyroid cancer (papillary, follicular, anaplastic) within the same family. To diagnose FNMTC, the clinician must exclude a syndromic presentation such as the syndromes of Cowden, Gardner or Werner, and the Carney Complex. Up to now, a hundred families with FNMTC have been genetically studied, including forms with (Ch19p13.2) or without oxyphilia (Ch2q21), in association with a multinodular goiter (Ch14q32), or with a renal cancer (Ch1q21). Several candidate genes of susceptibility have been proposed: SRGAP1, NKX2-1, FOXE1 and HABP2. So far, it is considered that familial cases represent less than 5 % of thyroid cancers. Although rare, these cases represent a unique opportunity to improve our understanding of thyroid cancer. The identification of candidate genes will enrich our knowledge of thyroid cancer pathophysiology. Based on the literature and our experience of the follow-up of eight families with FNMTC, we discuss epidemiological, clinical, pathological and genetic aspects of FNMTC with a view to improve the diagnosis and treatment of this disease.


Le syndrome de «Familial Non Medullary Thyroid Carcinoma¼ (FNMTC) suppose l'existence, au sein d'une même famille, de deux ou plusieurs patients avec un cancer thyroïdien non médullaire isolé (papillaire, folliculaire, anaplasique). Le diagnostic de FNMTC est retenu après exclusion d'une présentation syndromique comme celle liée aux syndromes de Cowden, Gardner, ou Werner et au Complexe de Carney. Une centaine de familles de FNMTC ont été bien caractérisées sur le plan génétique, incluant des formes papillaires avec (Ch19p13.2) ou sans oxyphilie (Ch2q21, 6q22), en association avec un goitre multinodulaire (14q32), ou avec un cancer rénal (Ch1q21). Plusieurs gènes de susceptibilité ont été proposés : SRGAP1, NKX2-1, FOXE1, et HABP2. On estime que les cas familiaux représentent moins de 5 % des cancers thyroïdiens. Bien que minoritaires, ils représentent une occasion exceptionnelle d'approfondir notre compréhension de la tumorigenèse du cancer thyroïdien et d'identifier des gènes candidats pouvant participer à leur physiopathologie. A partir d'une revue de la littérature et de notre expérience sur le suivi de huit familles avec FNMTC, nous discutons des aspects épidémiologiques, cliniques, pathologiques et génétiques permettant d'aboutir à un meilleur diagnostic et à une prise en charge de ce syndrome oncologique.

RESUMEN

UNLABELLED: The purpose of this study is to evaluate symptomatology, endoscopic and histopathologic changes of Helicobacter pylori infection and gastritis lesions without Helicobacter pylori infection on children diagnosed with celiac disease. MATERIAL AND METHOD: 15 children under gluten-free diet were selected and, because of the recurrence of the dyspeptic syndrome, an upper digestive endoscopy associated with histopathologic exam was performed. Considering the histopathologic result we made two groups: first group (8 children with celiac disease and Helicobacter pylori infection) and second group (7 children with celiac disease without Helicobacter pylori infection, but associated with gastritis lesions). RESULTS: The main symptom was diffuse abdominal pain in both groups. The endoscopic antrum aspects were congestive with striped aspect (first group--12.5%, second group--42.9%) and congestive with nodulation (first group--25%, second group--14.3%). The histopathologic diagnosis were: moderate active chronic pangastritis (first group--25%, second group--14.3%) moderate active chronic gastritis (first group--25%,second group--14.3%), lymphocytic gastritis (first group--12.5%, second group--14.3%). CONCLUSION: The histopathologic exam remains the gold standard for celiac disease, gastritis lesions and Helicobacter pylori infection.

RESUMEN

Many causes of thyroxine malabsorption are described in the literature, but the most common cause of failure of thyroxine therapy is poor patient compliance, or pseudomalabsorption. We describe the case of a female patient who underwent total thyroidectomy for Basedow-Graves disease. Post-operatively, several treatment regimens were employed to achieve euthyroidism, but only injectable thyroxine was found to be effective. To exclude levothyroxine malabsorption, the patient was hospitalized in a hypothyroid state while a single oral test dose of levothyroxine (1000 microg) was administered. Within 4 hours a decrease of TSH level (from 59.7 to 55.6 microUI/ml) and a significant increase in free T4 levels (from 0.8 to 15.5 pg/ml) was observed, eliminating a malabsorption problem. The cause of resistance to thyroid hormone therapy was poor patient compliance, leading to the designation of this as a case of pseudomalabsorption.

RESUMEN

The relationship between bronchial asthma (BA) and gastro-esophageal reflux (GER) impose to study by frequency, reciprocally prognosis and therapeutics difficulty. Coexistence of both diseases is suggested by presence of asthmatics symptoms in non-atopic patients, difficult control and resistance of the specific treatment of asthma disease, worsening of respiratory symptoms in circumstances which favored GER. Pathogenetic relationship between BA and GER in children is the result of the associations- digestive particularity and: esophago-bronchial neurogenic mechanism produced by micro-aspiration , genetic or obtained inflammations development by commune Th2 mediators, medications effects. Classical treatments (H2-inhibitors, prokinetics agents, inhibitors of protonic pumps) is associated of the antiasthmatics "controller" therapy and in the future, anti-cytokine and anti-receptor therapy.
