RESUMO

CONTEXT: Between 10% and 15% of people with hypothyroidism experience persistent symptoms, despite achieving biochemical euthyroidism. The underlying causes are unclear. Type D personality (a vulnerability factor for general psychological distress) is associated with poor health status and symptom burden but has not been studied in people with hypothyroidism. OBJECTIVE: To investigate type D personality in hypothyroidism and explore associations with other characteristics and patient-reported outcomes. DESIGN: Multinational, cross-sectional survey. SETTING: Online. PARTICIPANTS: Individuals with self-reported, treated hypothyroidism. INTERVENTION: Questionnaire. MAIN OUTCOME MEASURES: Type D personality and associations with baseline characteristics, control of the symptoms of hypothyroidism by medication, satisfaction with care and treatment of hypothyroidism, impact of hypothyroidism on everyday living. RESULTS: A total of 3915 responses were received, 3523 of which were valid. The prevalence of type D personality was 54.2%. Statistically significant associations were found between type D personality and several respondent characteristics (age, marital status, ethnicity, household income, comorbidities, type of treatment for hypothyroidism, most recent TSH level), anxiety, depression, somatization, poor control of the symptoms of hypothyroidism by medication, dissatisfaction with care and treatment of hypothyroidism, and a negative impact of hypothyroidism on everyday living). DISCUSSION: Our study found a high prevalence of type D personality among people with hypothyroidism who responded to the survey. Type D personality may be an important determinant of dissatisfaction with treatment and care among people with hypothyroidism. Our findings require independent confirmation. Close collaboration between the disciplines of thyroidology and psychology is likely to be key in progressing our understanding in this area.

RESUMO

OBJECTIVE: Hypothyroidism is a common endocrine condition usually managed with levothyroxine (LT4). However, controversy remains around the use of liothyronine (LT3). We aimed to investigate the practices of Australian endocrinologists when managing patients with hypothyroidism, their use of LT3 + LT4 combination therapy and use of thyroid hormones in euthyroid patients. DESIGN AND PARTICIPANTS: Members of the Endocrine Society of Australia (ESA) were invited to participate in an online questionnaire. MEASUREMENTS: We analysed questionnaires that had complete demographic data. RESULTS: Eighty-seven questionnaires fulfilled the criteria. LT4 was used as first line treatment for hypothyroidism by all respondents. Only 45% reported that their patients were dispensed the brand of LT4 that they recommend. LT3 (alone or in combination) was prescribed by 44% in their clinical practice. Although 49% of respondents would consider LT3 + LT4 in patients with normal TSH who had ongoing symptoms of hypothyroidism, the inability of LT4 to restore normal physiology was ranked the least likely explanation for persistent symptoms and only 32% would consider it for themselves if they were diagnosed with hypothyroidism. The majority (55%), in accordance with evidence, would not prescribe thyroid hormone to euthyroid individuals but 39% would consider use in euthyroid female infertility with high levels of thyroid antibodies and 11% in euthyroid patients with a simple goitre growing over time. LT4 use in pregnancy was variable among members. CONCLUSIONS: Australian endocrinologists mostly follow international guidelines when prescribing thyroid hormone therapy and many prescribe combination LT3 and LT4 therapy, particularly for patients who remain symptomatic on LT4 monotherapy. Prescribing practices are largely similar to other countries who have completed similar questionnaires.

RESUMO

Background: Hypothyroidism is common, however, aspects of its treatment remain controversial. Our survey aimed at documenting treatment choices of European thyroid specialists and exploring how patients' persistent symptoms, clinician demographics, and geo-economic factors relate to treatment choices. Methods: Seventeen thousand two hundred forty-seven thyroid specialists from 28 countries were invited to participate in an online questionnaire survey. The survey included respondent demographic data and treatment choices for hypothyroid patients with persistent symptoms. Geo-economic data for each country were included in the analyses. Results: The response rate was 32.9% (6058 respondents out of 17,247 invitees). Levothyroxine (LT4) was the initial treatment preferred by the majority (98.3%). Persistent symptoms despite normal serum thyrotropin (TSH) while receiving LT4 treatment were reported to affect up to 10.0% of patients by 75.4% of respondents, while 28.4% reported an increasing such trend in the past 5 years. The principal explanations offered for patients' persistent symptoms were psychosocial factors (77.1%), comorbidities (69.2%), and unrealistic patient expectations (61.0%). Combination treatment with LT4+liothyronine (LT3) was chosen by 40.0% of respondents for patients who complained of persistent symptoms despite a normal TSH. This option was selected more frequently by female thyroid specialists, with high-volume practice, working in countries with high gross national income per capita. Conclusions: The perception of patients' dissatisfaction reported by physicians seems lower than that described by hypothyroid patients in previous surveys. LT4+LT3 treatment is used frequently by thyroid specialists in Europe for persistent hypothyroid-like symptoms even if they generally attribute such symptoms to nonendocrine causes and despite the evidence of nonsuperiority of the combined over the LT4 therapy. Pressure by dissatisfied patients on their physicians for LT3-containing treatments is a likely explanation. The association of the therapeutic choices with the clinician demographic characteristics and geo-economic factors in Europe is a novel information and requires further investigation.

RESUMO

Introduction: Adult growth hormone deficiency (AGHD) is associated with a high prevalence of metabolic syndrome (MS), which contributes to the unfavorable cardiovascular risk profile in these patients. Insulin like growth factor-1 (IGF-1) is a widely used biomarker, however it does not always reflect the cardiometabolic risk and has a poor relationship with clinical efficacy endpoints. Consequently, there is an unmet need for biomarkers to monitor responses to GH-replacement. Afamin is a hormone-like glycoprotein, expressed in the liver. Higher afamin levels are strongly associated with MS and insulin resistance (IR). Although both MS and IR are very common in AGHD, afamin has not been investigated in these patients. Purpose: To investigate afamin as a potential biomarker in patients with AGHD. Materials and methods: Participants included 20 AGHD patients (11 GH-substituted and 9 GH-unsubstituted) and 37 healthy controls. Subjects underwent routine laboratory examinations, anthropometric measurements, body composition analysis using multi-frequency bioelectrical impedance analysis (InBody720) and measurement of serum afamin concentrations. In GH-substituted subjects, GH-substitution was withdrawn for 2 months. Measurements were carried out right before GH-withdrawal, at the end of the 2-month withdrawal period, and 1 month after reinstituting GH-replacement therapy (GHRT). Results: GH-unsubstituted patients demonstrated higher afamin levels compared to controls (p=0.03). Afamin positively correlated with skeletal muscle mass, bone mineral content, total body water, extracellular- and intracellular water content, insulin (all, p<0.01), HOMA-IR (p=0.01) and C-peptide (p=0.03) levels in AGHD but not in healthy controls. In GH-substituted patients 2-month of GH-withdrawal caused significant changes in body composition, including decreased fat-free mass, skeletal muscle mass, total body water, and intracellular water content (all, p<0.01); but these changes almost fully recovered 1 month after reinstituting GHRT. Unexpectedly, afamin levels decreased after GH-withdrawal (p=0.03) and increased with reinstitution (p<0.01). Changes of afamin levels during GH-withdrawal positively correlated with changes of HOMA-IR (r=0.80; p<0.01) and changes of insulin (r=0.71; p=0.02). Conclusion: Higher afamin levels in unsubstituted AGHD patients might indicate severe metabolic dysregulation. Significant changes accompanying GH-withdrawal and reinstitution, along with strong correlations with measures of IR, suggest that afamin could be a promising biomarker to monitor GHRT-associated changes of insulin sensitivity.

RESUMO

Introduction: Thyroid specialists influence how hypothyroid patients are treated, including patients managed in primary care. Given that physician characteristics influence patient care, this study aimed to explore thyroid specialist profiles and associations with geo-economic factors. Methods: Thyroid specialists from 28 countries were invited to respond to a questionnaire, Treatment of Hypothyroidism in Europe by Specialists: an International Survey (THESIS). Geographic regions were defined according to the United Nations Statistics Division. The national economic status was estimated using World Bank data on the gross national income per capita (GNI per capita). Results: 5,695 valid responses were received (response rate 33·0%). The mean age was 49 years, and 65·0% were female. The proportion of female respondents was lowest in Northern (45·6%) and highest in Eastern Europe (77·2%) (p <0·001). Respondent work volume, university affiliation and private practice differed significantly between countries (p<0·001). Age and GNI per capita were correlated inversely with the proportion of female respondents (p<0·01). GNI per capita was inversely related to the proportion of respondents working exclusively in private practice (p<0·011) and the proportion of respondents who treated >100 patients annually (p<0·01). Discussion: THESIS has demonstrated differences in characteristics of thyroid specialists at national and regional levels, strongly associated with GNI per capita. Hypothyroid patients in middle-income countries are more likely to encounter female thyroid specialists working in private practice, with a high workload, compared to high-income countries. Whether these differences influence the quality of care and patient satisfaction is unknown, but merits further study.

RESUMO

PURPOSE: Inconsistencies in the medical management of hypothyroidism have been reported between endocrinologists in different countries. This study aimed to identify the attitudes of Latin America thyroid specialists towards the use of thyroid hormones. METHODS: Online survey of members of the Latin America Thyroid Society. RESULTS: 81/446 (18.2%) completed the questionnaire. Levothyroxine (LT4) was the initial treatment of choice for all respondents. 56.8% would consider LT4 use in biochemically euthyroid patients: infertile women with elevated anti-thyroid antibodies (46.9%), resistant depression (17.3%) and growing goiter (12%). Most respondents preferred tablets (39.5%) over liquid formulations (21.0%) or soft gel capsules (22.2%) and would not consider switching formulations in patients with persistent symptoms. 39.5% would never use LT4 + liothyronine (LT3) combination therapy in symptomatic euthyroid patients, due to low quality evidence for benefit. 60.5% reported that persistence of symptoms despite normal TSH is rare (below 5% of patients) and its prevalence has been stable over the last five years. Psychosocial factors (84.0%), comorbidities (86.4%) and the patient unrealistic expectation (72.8%) were considered the top three explanations for this phenomenon. CONCLUSION: LT4 tablets is the treatment of choice for hypothyroidism. A significant proportion of respondents would use LT4 in some groups of euthyroid individuals, contrasting the recommendations of the major clinical practice guideline indications. LT4 + LT3 combination treatment in euthyroid symptomatic patients was considered by nearly 50%. Practices based on weak or absent evidence included use of thyroid hormones for euthyroid subjects by 56.8% of respondents and use of LT4 + LT3 treatment by 60.5% of respondents for patients with persistent symptoms. In contrast to many European countries, LATS respondents report a low and unchanged proportion of dissatisfied patients over the last five years.

RESUMO

Background: Advanced glycation end products (AGEs) are heterogenous group of irreversible chemical moieties originated from non-enzymatic glycation and oxidation of proteins, nucleic acids, and lipids. The engagement of AGEs with their chief cellular receptor (RAGE) activates a myriad of signaling pathways contributing to the progression of chronic diseases like autoimmune thyroiditis, type 2 diabetes mellitus and its complications. Soluble RAGE (sRAGE) prevents AGE-RAGE interaction in a competitive manner. Objective: We investigated the association between serum AGE, sRAGE and thyroid function in 73 Hashimoto thyroiditis patients (HT) on levothyroxine substitution, and in 83 age, BMI and gender-matched healthy controls. Methods: The serum AGEs levels were determined by autofluorescence on a multi-mode microplate reader, and the serum sRAGE levels by ELISA method. Results: Mean AGE level was lower (10.71 vs 11.45 AU/µg protein; p=0.046), while mean sRAGE level was higher (923 vs 755 pg/mL; p<0.0005) in the serum of HT patients than the controls. AGE correlated with age, while sRAGE correlated negatively with BMI in both groups. We found negative correlation between AGE and fT3 levels (r=-0.32; p=0.006) and sRAGE and TSH levels (r=-0.27; p=0.022) in HT patients, while we failed to find association between AGE, sRAGE and parameters of thyroid function in the control group. Median AGE/sRAGE ratio was lower in HT patients than in controls (2.4, IQR 1.9 - 3.1 vs 3.3, IQR 2.3 - 4.1 AU/pg; p < 0.001). In HT patients, the AGE/sRAGE ratio correlated positively with BMI and correlated negatively with fT3. Conclusion: According to our results in HT patients lower TSH and higher fT3 levels within the reference range is accompanied by a favorable AGE/RAGE balance. Further investigations are needed to confirm these results.

RESUMO

Background: Between 10% and 15% of hypothyroid patients experience persistent symptoms despite achieving biochemical euthyroidism. Unexplained persistent symptoms can be a sign of somatization. This is associated with distress and high health care resource use and can be classified as somatic symptom disorder (SSD). Prevalence rates for SSD differ depending on classification criteria and how they are ascertained, varying between 4% and 25%. As this has not been studied in hypothyroid patients before, the aim of this study was to document somatization in people with hypothyroidism and to explore associations with other patient characteristics and outcomes. Methods: Online, multinational cross-sectional survey of individuals with self-reported, treated hypothyroidism, which included the validated Patient Health Questionnaire-15 (PHQ-15) for assessment of somatization. Chi-squared tests with the Bonferroni correction were used to explore outcomes for respondents with a PHQ-15 score ≥10 (probable somatic symptom disorder [pSSD]) versus a PHQ-15 score <10 (absence of SSD). Results: A total of 3915 responses were received, 3516 of which contained the valid PHQ-15 data (89.8%). The median score was 11.3 (range 0-30 [confidence interval 10.9-11.3]). The prevalence of pSSD was 58.6%. Associations were found between pSSD and young age (p < 0.001), women (p < 0.001), not working (p < 0.001), having below average household income (p < 0.001), being treated with levothyroxine (LT4) (rather than combination of LT4 and L-triiodothyronine [LT3], LT3 alone, or desiccated thyroid extract) (p < 0.001), expression of the view that the thyroid medication taken did not control the symptoms of hypothyroidism well (p < 0.001), and with number of comorbidities (p < 0.001). pSSD was associated with respondent attribution of most PHQ-15 symptoms to the hypothyroidism or its treatment (p < 0.001), dissatisfaction with care and treatment of hypothyroidism (p < 0.001), a negative impact of hypothyroidism on daily living (p < 0.001), and with anxiety and low mood/depression (p < 0.001). Conclusions: This study demonstrates a high prevalence of pSSD among people with hypothyroidism and associations between pSSD and negative patient outcomes, including a tendency to attribute persistent symptoms to hypothyroidism or its treatment. SSD may be an important determinant of dissatisfaction with treatment and care among some hypothyroid patients.

RESUMO

Background: Splanchnic vein thrombosis due to co-existing metastatic pancreatic neuroendocrine tumour (pNET) and JAK2V617F mutation is a rare condition. Case report: Here we present a case of a young woman with complete remission of a non-functioning grade 2 pNET with unresectable liver metastases, coexisting with JAK2V617F mutation. Splenectomy and distal pancreatectomy were performed. Neither surgical removal, nor radiofrequency ablation of the liver metastases was possible. Therefore, somatostatin analogue (SSA) and enoxaparine were started. Peptide receptor radionuclide therapy (PRRT) was given in 3 cycles 6-8 weeks apart. Genetic testing revealed no multiple endocrine neoplasia type 1 (MEN-1) gene mutations. After shared decision making with the patient, she gave birth to two healthy children, currently 2 and 4 years old. On pregnancy confirmation, SSA treatment was interrupted and resumed after each delivery. Ten years after the diagnosis of pNET, no tumour is detectable by MRI or somatostatin receptor scintigraphy. PRRT followed by continuous SSA therapy, interrupted only during pregnancies, resulted in complete remission and enabled the patient to complete two successful pregnancies.

RESUMO

Objective: Thyroid nodule ultrasound characteristics are used as an indication for fine-needle aspiration cytology, usually as the basis for Thyroid Imaging Reporting and Data System (TIRADS) score calculation. Few studies on interobserver variation are available, all of which are based on analysis of preselected still ultrasound images and often lack surgical confirmation. Methods: After the blinded online evaluation of video recordings of the ultrasound examinations of 47 consecutive malignant and 76 consecutive benign thyroid lesions, 7 experts from 7 thyroid centers answered 17 TIRADS-related questions. Surgical histology was the reference standard. Interobserver variations of each ultrasound characteristic were compared using Gwet's AC1 inter-rater coefficients; higher values mean better concordance, the maximum being 1.0. Results: On a scale from 0.0 to 1.0, the Gwet's AC1 values were 0.34, 0.53, 0.72, and 0.79 for the four most important features in decision-making, i.e. irregular margins, microcalcifications, echogenicity, and extrathyroidal extension, respectively. The concordance in the discrimination between mildly/moderately and very hypoechogenic nodules was 0.17. The smaller the nodule size the better the agreement in echogenicity, and the larger the nodule size the better the agreement on the presence of microcalcifications. Extrathyroidal extension was correctly identified in just 45.8% of the cases. Conclusions: Examination of video recordings, closely simulating the real-world situation, revealed substantial interobserver variation in the interpretation of each of the four most important ultrasound characteristics. In view of the importance for the management of thyroid nodules, unambiguous and widely accepted definitions of each nodule characteristic are warranted, although it remains to be investigated whether this diminishes observer variation.

RESUMO

BACKGROUND: Replacement of thyroid hormones (TH) with Levothyroxine (LT4) is the treatment of choice for hypothyroidism, however, there are aspects of treatment where uncertainties exist and practice varies. Factors influencing initiation and choice of TH replacement may impact patient satisfaction, safety, and health care costs. METHODS: The aim of the study was to examine the attitudes of Irish endocrinologists regarding the treatment of hypothyroid and euthyroid patients with TH. Members of the Irish Endocrine Society (IES) were invited to participate in an online survey. RESULTS: Forty-eight invitations were sent, and 39 (81.3%) participants responded. All respondents favoured LT4 tablet therapy for treatment of hypothyroidism, but 20.5% prescribed combination therapy (LT4 and liothyronine), and 13% regularly used desiccated thyroid extract. A significant proportion (51%) might prescribe TH in euthyroid patients; 41% for thyroid auto-antibody positive women seeking pregnancy, 18% for goitre and 5% for unexplained fatigue. Many (38%) consider combination therapy in patients with persistent symptoms. Respondents reported seeing LT4 treated patients with persistent symptomatology more frequently and perceive psychosocial factors and comorbidities to be the most common reasons for such symptoms. CONCLUSION: LT4 tablets are the treatment of choice for hypothyroidism in Ireland. Approximately a third of Irish endocrinologists either regularly use, or would consider, liothyronine for hypothyroid patients. A significant proportion would give TH to euthyroid individuals in specific circumstances. The prescription of TH amongst Irish endocrinologists was generally in keeping with recommended practice, and areas where practice deviated from guidance were typically where evidence was conflicting or insufficient.

RESUMO

OBJECTIVE: Management of hypothyroidism is controversial because of medication cost pressures and scientific uncertainty on how to address treatment dissatisfaction experienced by some patients. The objective was to investigate the experience and preferences of UK endocrinologists in use of thyroid hormones. DESIGN: Web-based survey. PATIENTS: UK endocrinologists were invited to participate. MEASUREMENTS: Responses to questionnaire. RESULTS: The response rate was 21% (272/1295). While levothyroxine monotherapy is regarded as the treatment of choice for hypothyroidism, 51% of respondents stated that combined treatment with levothyroxine and liothyronine could be considered for levothyroxine-treated patients whose symptoms persist despite normalisation of serum thyroid stimulating hormone (TSH) concentration. However, only 40% are currently prescribing such treatment, and just 23% would consider taking it themselves. A small minority prescribe desiccated thyroid extract, and those most likely to do so are aged over 60 years. Most respondents stated that they have no influence over brand or formulation of levothyroxine dispensed to their patients and expect no major differences in efficacy between different formulations. A total of 9% would prescribe levothyroxine for euthyroid enlarging goitre, and 29% for euthyroid female infertility with high titre thyroid peroxidase antibodies, despite recent trials finding no benefit. CONCLUSIONS: UK endocrine practice in management of hypothyroidism is broadly in line with international guidance. However, a minority of respondents would consider thyroid hormone supplementation in euthyroid individuals for female infertility, enlarging goitre, and other indications in which evidence of efficacy is lacking. Willingness to consider prescribing combined levothyroxine and liothyronine, for hypothyroid symptoms which persist despite normalised TSH, has increased in comparison to previous international surveys, despite inconsistent evidence of benefit.

RESUMO

A significant minority of patients with hypothyroidism report persistent symptoms despite achieving normal thyroid biochemistry after levothyroxine (L-T4) replacement. Four principal lines of thinking, which are not mutually exclusive, may explain this enigma. The 'low tissue liothyronine hypothesis' emphasizes the potential imperfections of L-T4 replacement therapy that may lead to hypothyroidism in some tissues such as the brain, while others (eg hypothalamus) are euthyroid. The 'Somatic Symptom and Related Disorders hypothesis' draws attention to an incidental coexistence of a diagnosis of Somatic Symptom and Related Disorders in patients with treated hypothyroidism. The 'autoimmune neuroinflammation hypothesis' highlights the potential consequences of inflammatory mediators due to thyroid autoimmunity (the commonest cause of hypothyroidism) on the brain. The 'comorbidities and psychosocial hypothesis' implicates a variety of physical and psychosocial factors that have been noted to be associated with a diagnosis of hypothyroidism, which may be primarily the cause of persistent complaints. Over the past twenty years, a great deal of time and effort has been expended pursuing the 'low tissue liothyronine hypothesis', which has failed to yield results that translate to patient benefits. This has skewed the balance in clinical practice, in favour of pursuing answers relating to L-T4 and liothyronine combination treatment, while the alternative explanations have been downplayed and potentially useful interventions have been given insufficient attention.

RESUMO

BACKGROUND: Currently there are no widely applied methods which could identify, at the time of head trauma, those mild traumatic brain injury (mTBI) patients who later develop pituitary dysfunction. The effect of alcohol consumption on post-TBI endocrine dysfunction is unclear. METHODS: Five hundred and eight TBI patients, 406 of them with mTBI, were studied. Sixty-one patients (46 males, 15 females) were available for follow-up. Admission serum samples were evaluated for S100B protein and markers of alcohol consumption: ethanol level for day-of-injury intake and carbohydrate deficient transferrin (CDT) level for regular alcohol consumption. Regular alcohol consumption was defined as CDT > 1.5%, including both social and heavy drinkers. Admission and one-year follow-up samples were evaluated for pituitary dysfunction. RESULTS: Newly developed pituitary hormone deficiency was found in 16% of mTBI patients. When cohorts developing and not developing late pituitary dysfunction were compared, 30% and 69% of patients were regular alcohol consumers, respectively (p = 0.02). Neither S100B level nor day-of-injury alcohol consumption was predictive of late pituitary dysfunction. CONCLUSION: The findings of this preliminary study suggest that regular alcohol consumption may protect against the late endocrine consequences of mTBI. Alcohol intake during the weeks preceding mTBI may identify patients at higher risk for late pituitary dysfunction.

RESUMO

BACKGROUND: Hypothyroidism is one of the leading conditions in endocrinology. Despite that fact, clinical indications for treatment still vary among Spanish specialists. AIMS: To identify attitudes of Spanish specialists relating to the use of levothyroxine (LT4) and the management of hypothyroidism. METHODS: The members of the Sociedad Española de Endocrinología y Nutrición (Spanish Society of Endocrinology and Nutrition) were invited to participate in a web-based survey. The survey, initially in English, was modified to reflect in accordance with the availability of thyroid hormone formulations in Spain. RESULTS: A total of 505 of 1956 (25.8%) members (66% female) completed the survey; 97.4% declared that LT4 is the first-line therapy for hypothyroidism. The indications for LT4 therapy in euthyroidism were infertility in thyroid antibody-positive women (48.5%) and simple goitre (21.2%). However, 44.2% of specialists reported that there was no indication for LT4 therapy in such patients. Only a minority of respondents (2.6%) considered combining LT4 with liothyronine as the treatment of choice from inception, whereas 49% stated that it should never be used. CONCLUSIONS: The standard of treatment of hypothyroidism in Spain is almost exclusively with LT4 tablets. Availability of other formulations of LT4 or combination therapy for hypothyroidism management remains to be explored, especially in patients with persistent symptoms. Notably, non-evidence-based use of LT4 is widely practiced in Spain for euthyroid women with autoimmune thyroiditis and fertility issues.

RESUMO

Background: Hypothyroid patients often report dissatisfaction and poor quality of life. This survey explored the impact of hypothyroidism on patient satisfaction, everyday living, experiences with health care professionals, and influence of demographic and socioeconomic factors. Methods: Cross-sectional questionnaire survey targeting an international population of hypothyroid patients. Multilevel regression modeling was used for analyses. Results: The total number of responses was 3915 from 68 countries. Satisfaction with care and treatment was not associated with type of treatment for hypothyroidism. Having no confidence and trust in health care professionals was strongly associated with dissatisfaction (p < 0.001). Controlling for all other variables, significant differences were found among satisfaction rates between countries. A weak inverse relationship was found between satisfaction with care and treatment and impact on everyday living (p < 0.001). Respondents taking levothyroxine (LT4) alone were more likely to report a positive impact on everyday living (pooled odds ratio 2.376 [confidence interval: 0.941-5.997]) than respondents taking liothyronine-containing treatments. Conclusions: Low levels of satisfaction with care and treatment for hypothyroidism were strongly associated with lack of confidence and trust and negative experiences with health care professionals. Differences in responses between countries were noted, implying the potential influence of national health care systems, socioeconomic and cultural factors. Contrary to widespread anecdotes in social media, this large-scale survey shows no association between type of treatment for hypothyroidism and patient satisfaction, as well as better outcomes on everyday living associated with LT4, compared with liothyronine-containing treatments.

RESUMO

Background: The thyroid eye disease (TED) treatment landscape is rapidly evolving. How new treatment options have impacted practice is unknown. Methods: We conducted a cross-sectional electronic survey of American and European Thyroid Association members between June 2 and June 30, 2021. The survey included TED questions about resources for its management, index cases for different severities and presentations of TED, barriers for the management of TED, and participants' concerns about TED. We classified respondents into three geographic categories: North America, Europe, or other regions. Results: Two hundred fifty-two eligible participants started the survey (15% response rate), and 227 completed it. Participants were mostly men (50.2%, 114/227), white (79.7%, 181/227), endocrinologists with a thyroid focus (66.1%, 150/227), practicing in a tertiary academic center (46.7%, 106/227), caring for 10 or more TED patients over the last 12 months (40.5%, 92/227), and reported not having a multidisciplinary TED clinic in their institution (52.8%, 120/227). The majority reported that new TED cases per annum have not changed in the past 10 years (47.5%, 108/227), and that TED patients are found in practice during the management of hyperthyroidism (41.8%, 95/227). For mild active TED, participants from Europe reported a higher use of selenium (73%[96/132] vs. 32%[20/62] of respondents from North America and 24%[8/33] of respondents from other regions). For moderate-to-severe active TED, there was a modest preference for teprotumumab as first-line therapy (37%, 23/62) among North American participants and intravenous (IV) steroids (73%[96/132], and 42%[14/33]) for participants from Europe and other regions, respectively. These treatment preferences did not change in patients with moderate-to-severe active TED with poorly controlled diabetes. In contrast, participants from the three geographic categories preferred IV steroids for optic neuropathy and women planning pregnancy. The three top "very important" concerns about TED management according to participants were: the cost of TED treatment (31.3%, 71/227), lack of effective TED treatments (19.8%, 45/227), and difficulty in predicting whether TED will develop (18.9%, 43/227). Conclusions: There is a marked geographic practice variation in the management of TED. Clinicians' concerns about TED management demand ongoing research on more effective treatment, TED predictive tools, and policy changes to improve the affordability of new TED therapies.

RESUMO

Introduction: Dysthyroid optic neuropathy (DON) is a rare, severe form of thyroid eye disease, in which decreased visual acuity is accompanied by characteristic MRI findings. The treatment of DON has always been a challenge. Case presentation: In a patient in whom visual acuity deteriorated on the left eye, mannitol 20% 200 mL followed by furosemide 40 mg 6 h later, administered daily, were initiated on the day of admission. Visual function by ophthalmology methods, and orbital compartment volumes and water content by MRI were followed. Intravenous diuretics resulted in an immediate therapeutic response. Visual acuity improved from 20/50 to 20/25 after 2 days of treatment. MRI revealed decreasing water content of both the muscle and connective tissue compartments without any volume changes. Subsequently, corticosteroids and orbital irradiation were started. Orbital decompression surgery was not required. Discussion/conclusion: Edematous swelling of orbital tissues is an established contributor of local pressure increase in thyroid eye disease. Diuretics reduce orbital pressure and, if confirmed by others, may be useful additions to the standard of care in sight-threatening DON.

RESUMO

Introduction and aims. In recent decades health care changes have accelerated enormously. Previously, by learning an effective procedure, the doctor could guarantee his patients the highest level of care for many years. Nowadays, due to the dynamics of development, the renewal cycles of the methods have been shortened, without continuous learning and training, it is already inconceivable to provide the up-to-date care required by patients. Patients and methods. Instead of vascular replacements with prosthetic grafts, which played an important role in vascular reconstructions, the primacy of endovascular techniques has become decisive. It can be significant for aortic aneurysms that can be operated with high invasiveness. The learning of catheter techniques by vascular surgeons made it possible to treat more successfully those limb-threatening cases, which are often associated with extensive vascular involvement, through the so-called hybrid operations. In addition to the increasing prevalence of diabetes worldwide, the higher proportion of critical limb ischemia and the highlighted pathogenic role of multi-resistant bacteria in the disease caused the marginaliation of the use of previously preferred prosthetic grafts. The effectiveness of the treatment of graft infections, which thus become less frequent, is improved by the use of homografts and negative pressure therapy. An effective method of preventing stroke is carotid endarterectomy, the morbidity of which is reduced by the introduction of locoregional anaesthesia allowing direct neuromonitoring. Results/conclusions. Although the acquisition and implementation of new methods has posed a continuous challenge for our specialists and doctors over the past 10 years, our achievements have made our department one of the leading vascular surgery centres in the country.

RESUMO

Thyroid autoimmunity in Graves' disease (GD) is accompanied by Graves' orbitopathy (GO) in 40% of the cases. Orbital fibroblasts (OF) play a key role in the pathogenesis and cigarette smoking is a known deteriorating factor. Alongside conventional cigarettes (CC) new alternatives became available for smokers, including heated tobacco products (HTP) and E-cigarettes (ECIG). We aimed to study the cellular effects of smoke extracts (SE) in orbital fibroblasts. Primary OF cultures from GO and NON-GO orbits were exposed to different concentrations of SE (1%, 50%) and the changes were followed using Real Time Cell Electronic Sensing (RT-CES). Untreated GO and NON-GO cells had different maximum cell index (CI) values of 3.3 and 2.79 respectively (p < 0.0001). CC, HTP and ECIG treated NON-GO fibroblasts exhibited peak CIs of 2.62, 3.32 and 3.41 while treated GO cells' CIs were higher, 5.38, 6.25 and 6.33, respectively (p < 0.0001). The metabolic activity (MTT) decreased (p < 0.001) and hyaluronan production doubled (p < 0.02) after 50% of CC SE treatment in all cell cultures. GO fibroblasts were more sensitive to low concentration SE then NON-GO fibroblasts (p < 0.0001). The studied SEs exerted different effects. RT-CES is a sensitive technique to detect the effects of very low concentration of SE on fibroblasts.
