Total thyroidectomy for Graves' disease-what do our patients think? A qualitative cohort study to evaluate the surgical management of Graves' disease.

INTRODUCTION: Total thyroidectomy for Grave's disease has been covered extensively in literature. There are established risks and side effects of the procedure, but in experienced hands, this is minimised. Studies show the physical complication rate of total thyroidectomy, but not a holistic view. The authors pose the question, "what do our patients really think"? Has there been a significant improvement in quality of life by doing this surgery? METHODS: A cohort of patients who underwent total thyroidectomy for Graves' disease between the dates 2015-2018. A total of 95 patients were identified. The Glasgow Benefit Inventory (GBI) was used to ascertain patient's opinions on their surgery. RESULTS: There were 54 responders, 46 female and 8 male. Average age was 41, with a range 20-81. Average GBI scores were 13.35 (SD 30.16). A general subset had an average score of 19.21 (SD = 32.59), a social subset average was 9.57 (SD = 25.61), and a physical subset was average -6.79 (SD = 37.40). Patients' feedback included positive and negative statements on their feelings surrounding pre-operative communication and post-operative side effects. CONCLUSION: Overall, the GBI scores are positive, thereby showing an improvement in quality of life since having total thyroidectomy for Graves. Pre-operative communication was of paramount importance. It should be made clear to patients that they will require medication after surgery. The majority of patients stated they would prefer to know about "minor" post -operative side effects like weight gain or mood change post op. This highlights the importance of the consenting process- Montgomery Ruling-that clinicians explain the risks involved with surgery according to what the patient would deem a risk. In addition, they must be informed of the non-surgical options available, therefore, surgeons should be able to discuss risks and benefits of radio-iodine and anti-thyroid drugs too.

Related quality of life questionnaire specific to dysthyroid ophthalmopathy evaluated in a population of patients with Graves' disease

ABSTRACT Objective The aim of this study was to measure quality of life (QOL) impairment in individuals currently suffering from Graves' ophthalmopathy (GO) and to determine the correlation of GO-specific QOL scores with disease severity and activity. Subjects and methods Seventy three GO-specific QOL surveys were prospectively analysed and compared with GO status. The GO-specific QOL survey was translated into Spanish and applied to Argentine patients with Graves' disease (GD). Results were compared with presence or absence of GO, Clinical Activity Score (CAS), severity score, age, gender and thyroid function. Results Fifty-six patients answered the survey and underwent complete ophthalmic evaluation, 15 did not have GO and were considered to be a control group. Appearance QOL score for patients with GO (53 ± 31.4) was lower than the control group (88.3 ± 17) (p < 0,000), no difference was observed in functional QOL score. There was a negative correlation between GO severity and both functional (r = -0.575; p < 0.000) and appearance QOL (r = -0.577; p < 0.000). Functional QOL differed between patients with active GO vs control group (p = 0.043). Patients with active and inactive GO had lower appearance QOL scores than control group (p < 0.000, p < 0.001 respectively). Conclusions GO has significant impact on the life of these Argentine patients. QOL was worse in GO patients than in control group, functional QOL was mostly affected by the activity and appearance QOL was mainly altered by the effects of the disease. Patients with more severe GO had lower scores on both QOL scales.

Quality-of-Life Impairments Persist Six Months After Treatment of Graves' Hyperthyroidism and Toxic Nodular Goiter: A Prospective Cohort Study.

BACKGROUND: The treatment of hyperthyroidism is aimed at improving health-related quality of life (HRQoL) and reducing morbidity and mortality. However, few studies have used validated questionnaires to assess HRQoL prospectively in such patients. The purpose of this study was to assess the impact of hyperthyroidism and its treatment on HRQoL using validated disease-specific and generic questionnaires. METHODS: This prospective cohort study enrolled 88 patients with Graves' hyperthyroidism and 68 with toxic nodular goiter from endocrine outpatient clinics at two Danish university hospitals. The patients were treated with antithyroid drugs, radioactive iodine, or surgery. Disease-specific and generic HRQoL were assessed using the thyroid-related patient-reported outcome (ThyPRO) and the Medical Outcomes Study 36-item Short Form (SF-36), respectively, evaluated at baseline and six-month follow-up. The scores were compared with those from two general population samples who completed ThyPRO (n = 739) and SF-36 (n = 6638). RESULTS: Baseline scores for patients with Graves' hyperthyroidism and toxic nodular goiter were significantly worse than those for the general population scores on all comparable ThyPRO scales and all SF-36 scales and component summaries. ThyPRO scores improved significantly with treatment on all scales in Graves' hyperthyroidism and four scales in toxic nodular goiter, while SF-36 scores improved on five scales and both component summaries in Graves' hyperthyroidism and only one scale in toxic nodular goiter. In Graves' hyperthyroidism, large treatment effects were observed on three ThyPRO scales (Hyperthyroid Symptoms, Tiredness, Overall HRQoL) and moderate effects on three scales (Anxiety, Emotional Susceptibility, Impaired Daily Life), while moderate effects were seen in two ThyPRO scales in toxic nodular goiter (Anxiety, Overall HRQoL). However, significant disease-specific and generic HRQoL deficits persisted on multiple domains across both patient groups. CONCLUSIONS: Graves' hyperthyroidism and toxic nodular goiter cause severe disease-specific and generic HRQoL impairments, and HRQoL deficits persist in both patient groups six months after treatment. These data have the potential to improve communication between physicians and patients by offering realistic estimates of expected HRQoL impairments and treatment effects. Future studies should identify risk factors for persistent HRQoL deficits, compare HRQoL effects of the various therapies, and thereby aid in determining the optimal treatment strategies.

Acute psychosis in a pregnant patient with Graves' hyperthyroidism and anti-NMDA receptor encephalitis.

A previously healthy 36-year-old woman presented with visual hallucinations and acute psychosis manifested predominantly as hypersexuality. Laboratory testing demonstrated elevated free thyroxine levels, suppressed thyroid-stimulating hormone levels and presence of thyroid-stimulating immunoglobulin and thyroid peroxidase (TPO) antibodies consistent with Graves' disease. Despite achieving biochemical euthyroidism, she remained profoundly hypersexual. She did not respond to additional treatment with antipsychotics and corticosteroids, prompting further evaluation. Cerebrospinal fluid analysis detected pleocytosis, elevated IgG, and presence of antibodies against anti-N-methyl-D-aspartate receptor (NMDAR), glutamic acid decarboxylase 65 and TPO. These results suggested a diagnosis of anti-NMDAR encephalitis. Prior to initiation of immunomodulator therapy, she was discovered to be pregnant with date of conception around the time of her original presentation. She received plasmapheresis with resolution of psychosis and decrease in free thyroxine levels. Graves' disease remitted during the remainder of the pregnancy but relapsed 5 months post partum. She has not had further neuropsychiatric symptoms.

Clinical and socioeconomic factors influence treatment decisions in Graves' disease.

BACKGROUND: Definitive treatment of Graves' disease includes radioactive iodine (RAI) and thyroidectomy, but utilization varies. We hypothesize that, in addition to clinical reasons, there are socioeconomic factors that influence whether a patient undergoes thyroidectomy or RAI. METHODS: Patients treated for Graves' disease between August 2007 and September 2013 at our university hospital were included. A comparative analysis of clinical and socioeconomic factors was completed. RESULTS: Of 427 patients, 300 (70 %) underwent RAI, whereas 127 (30 %) underwent surgery. Multiple factors were associated with surgery: younger age (mean 36 vs. 41 years, p < 0.01), female gender (33 vs. 19 % males, p = 0.01), black race (56 vs. 28 % nonblack, p < 0.01), Medicaid or uninsured (43 vs. 27 % private insurance or Medicare, p < 0.01), ophthalmopathy (38 vs. 26 %, p < 0.01), goiter (35 vs. 23 %, p < 0.01), and lowest quartile of median household income (38 vs. 27 % upper three quartiles, p = 0.03). Thyroidectomy increased annually, with 52 % undergoing surgery during the final year (p < 0.01). Adjusting for confounding, younger age (odds ratio [OR] 1.04; 95 % confidence interval [CI] 1.02, 1.05), female gender (OR 2.06; 95 % CI 1.06, 4.01), ophthalmopathy (OR 2.35; 95 % CI 1.40, 3.96), and later year of treatment (OR 1.66; 95 % CI 1.41, 1.95) remained significantly associated with surgery. CONCLUSIONS: Surgery has now become the primary treatment modality of choice for Graves' disease at our institution. Clinical factors are the main drivers behind treatment choice, but patients with lower SES are more likely to have clinical features best treated with surgery, underlying the importance of improving access to quality surgical care for all patients.

[The polyglandular autoimmune syndrome--quality of life and family clustering]. / Das polyglanduläre Autoimmunsyndrom--Lebensqualität und familiäre Beteiligung.

BACKGROUND AND AIM: For patients with polyglandular autoimmune syndrome (PGA), data pertaining to familial clustering and quality of life are missing. Therefore, we performed a prospective and controlled study to collect this information. PATIENTS AND METHODS: Clinical and serological evaluation of 75 consecutively recruited patients with PGA (mean age 47,5 ± 15,3 years; 65,3% women) and their 108 relatives (mean age 33,13 ± 20,08 years; 65,7% women) was performed. Three validated questionnaires for psychosocial evaluation (quality of life short form 36 [SF-36], hospital anxiety and depression scale [HADS] and the Gießener Beschwerdebogen [GBB]) were answered by patients and relatives. RESULTS: 47 (62%) patients with PGA had type 1 diabetes and autoimmune thyroid disease. 56 (52%) of their relatives had an autoimmune disease whereas Hashimoto's thyroiditis and type-A-gastritis were the most prevalent endocrine and non-endocrine components. Thyroid peroxidase autoantibodies were most prevalent in patients and involved relatives. Compared to a German reference group, all scales of the SF-36 were markedly decreased in patients and involved relatives (p < 0.001). Anxiety and depression scales were pathologically increased in patients and relatives (p < 0.001). Also, all GBB scales were elevated for patients and relatives (p < 0.001). Patients with both glandular and non-glandular autoimmune diseases showed the most pathological psychosocial results. CONCLUSION: Familial clustering is high in patients with PGA. Quality of life and psychosocial status are poor in patients and involved relatives. Multidisciplinary management of the multiplex families in specialized centers is warranted.

Does thyroid surgery for Graves' disease improve health-related quality of life?

PURPOSE: Graves' disease can induce alterations of the psychosocial well-being that negatively influence the overall well-being of patients. Among the current treatments, surgery has limited indications, and its impact on the health-related quality of life has not been well clarified. The aim of this study was to assess the impact of surgery on the quality of life. METHODS: Fifty-seven patients who underwent total thyroidectomy for Graves' disease in our surgical unit between April 2002 and December 2009 were administered a questionnaire concerning four issues: organic alterations and clinical manifestations, neurovegetative system disturbances, impairment of daily activities, psychosocial problems. Patients were retrospectively questioned after thyroidectomy about the presence of these symptoms in both the pre and postoperative periods. RESULTS: There was a significant improvement after surgery in all four areas. Organic manifestations and psychosocial problems had higher average improvements, as did some aspects of the neurovegetative system and difficulties in undertaking daily activities. There were no reports of a worsening of symptoms. CONCLUSIONS: Surgery resolved the hyperthyroidism in 100 % of cases, and was associated with a quality of life improvement of about 70 % in the patients. Surgery can therefore provide an immediate and effective resolution of Graves' disease, with benefits in health-related quality of life.

Total versus near-total thyroidectomy in Graves' disease and their outcome on postoperative transient hypoparathyroidism: study protocol for a randomized controlled trial?

BACKGROUND: Graves' disease is an independent risk factor for transient postoperative hypoparathyroidism. Besides the disease itself, preparation techniques are influential. Transient postoperative hypoparathyroidism has severe consequences for patients' physical and psychological state. It can be life threatening during the acute phase and may impair patients' health, psyche and quality of life thereafter. For the surgical therapy of Graves' disease, total thyroidectomy is recommended according to the national S2-guideline. The evidence- based on a metaanalysis- is criticized by the Cochrane diagnostic review commentary for substantial methodological deficits. Two randomized controlled trials lead to the hypothesis that a near-total resection with bilateral remnants of ≤ 1g on each side compared to total thyroidectomy will significantly reduce the occurrence of transient postoperative hypoparathyroidism with equal therapeutic safety. METHODS/DESIGN: Patients with Graves' disease indicated for definite surgery are eligible for the trial. Trial-specific exclusion criteria are: conservative treatment, malignancy, previous thyroid surgery and coincident hypoparathyroidism. The trial is created for therapeutic purpose through process innovation. It is designed as a prospective randomized controlled patient and observer blinded multicentered trial in a parallel design including an active comparator and an intervention group. The intervention addresses the surgical procedure: near-total thyroidectomy leaving bilateral remnants of ≤ 1g on each side in the intervention group and total thyroidectomy in the control group. The occurrence of transient postoperative hypoparathyroidism is defined as primary endpoint. Secondary endpoints are: reoperations due to bleeding, recurrent laryngeal nerve palsy, permanent hypoparathyroidism, recurrent disease, changes of endocrine orbitopathy and quality of life within a one-year follow-up period. The primary efficacy analysis follows the intention-to-treat principle. A binary logistic regression model will be applied. Complications and serious adverse events will be descriptively analyzed. DISCUSSION: The trail is expected to balance out the shortcomings of the current evidence. It will define the surgical gold standard for the surgical therapy of Graves' disease. Patients' safety and quality of life are assumed to be enhanced. Therapy costs are likely to be reduced and health care optimized. The conduction of the trial is feasible through the engagement and commitment of the German association of endocrine surgeons and the National Network for Surgical Trials. TRIAL REGISTRATION: German clinical trials register (DRKS) DRKS00004161.

Quality of life after surgery for Graves' disease: comparison of those having surgery intended to preserve thyroid function with those having ablative surgery.

BACKGROUND: Postoperative quality of life (QoL) after surgery for Graves' disease is not well documented, and the effect of different surgical operations has not been compared. This study examines the impact on QoL of a shift in policy from operations intended to preserve thyroid function (PF) to those ablating thyroid function (AF). METHODS: A cross-sectional assessment was performed on patients who underwent surgery for Graves' disease between 1986 and 2008 in a tertiary endocrine surgical unit. Patients completed the Short Form 36 (SF-36) questionnaire by post. SF-36 scores, including the physical and mental component summaries, were compared with the general population and by operative intent (AF vs. PF). Statistical analyses were performed using SPSS 16.0. RESULTS: Of 150 patients, 3 had died of unrelated causes and 14 were not contactable. In the remaining 133 patients, the median age at time of assessment was 46 years (interquartile range 42-50) and 43 years (interquartile range 33-47) in the PF and AF groups, respectively. From these patients, 87 questionnaires (65.4% response rate) were completed with an item completion rate of 99.3%. The median follow-up was 18.4 years for PF and 7.9 years for AF surgery. Of 87 respondents, 38 (43.7%) underwent PF and 49 (56.3%) AF surgery. Study participants reported lower scores across all SF-36 subscales than British norms (p<0.05). Comparisons on operative intent showed no significant difference in long-term QoL (p>0.05). CONCLUSION: The shift to ablative surgery simplifies postoperative management with no adverse effect on QoL, justifying this practice from a patient perspective.

Approach to the pediatric patient with Graves' disease: when is definitive therapy warranted?

Pediatric Graves' disease accounts for 10-15% of thyroid disorders in patients less than 18 yr of age. The onset of symptoms may be insidious and subsequently associated with a delay in diagnosis. Decreased concentration and poor school performance are frequent complaints and can be quite frustrating for the patient and family. Severe ophthalmopathy is uncommon. The diagnosis is established by the findings of an increased heart rate and goiter in the setting of a suppressed TSH and elevated T(3) and/or T(4). The majority of pediatric patients are initially placed on antithyroid medications and maintained on these medications for prolonged periods of time in hopes of achieving remission. Unfortunately, for many children and adolescents remission is unattainable, ultimately occurring in only 15-30% of patients. Several recent studies have suggested that the age of the patient, the degree of thyrotoxicosis at diagnosis, the initial response to therapy, and the level of TSH receptor antibodies serve as reasonable predictors of remission and relapse. However, a consensus on the utility of these markers has not been reached. The present clinical case describes an adolescent with Graves' disease and highlights the negative impact that prolonged medical therapy can have on quality of life and school performance; it reviews pertinent data on the diagnosis, comorbidities, and treatment options; and it identifies gaps in knowledge for when definitive therapy should be pursued. The case serves as a reminder that earlier discussion and decision for definitive therapy should be more commonplace in caring for our pediatric patients with Graves' disease.

Auto-estima na forma inativa da oftalmopatia de Graves / Inactive Graves' ophthalmopathy and self-esteem

OBJETIVOS: Avaliar a auto-estima dos pacientes com oftalmopatia de Graves na fase inativa. MÉTODOS: Foram avaliados 30 pacientes portadores de oftalmopatia de Graves, eutireoideanos, na fase inativa, com idade variando entre 26 e 65 anos, média 43 ± 11,0 anos, denominado grupo estudo e 39 indivíduos que não apresentavam oftalmopatia de Graves, com idade variando entre 18 e 67 anos, média de 41 ± 13,4 anos, selecionados na população geral denominado grupo controle. Para avaliar a auto-estima foi utilizada a escala de auto-estima Rosenberg Unifesp-EPM aplicada por meio de entrevista. Os valores dos escores de auto-estima nos dois grupos estudados foram comparados pelo teste não paramétrico de Mann-Whitney. O mesmo teste foi aplicado com objetivo de comparar os resultados obtidos no grupo oftalmopatia de Graves considerando a gravidade da doença. RESULTADOS: Não foi observada alteração com significância estatística na auto-estima dos pacientes com oftalmopatia de Graves (p=0,057). O grupo estudo apresentou, em média, valores inferiores de auto-estima, comparado ao grupo controle. Não houve diferença da auto-estima entre os pacientes dos subgrupos leve e moderado-grave (P=0,2710). CONCLUSÃO: A oftalmopatia de Graves na fase inativa não afetou a auto-estima dos pacientes, no grupo estudado.

PURPOSE: To assess the self-esteem of Graves' ophthalmopathy patients in the inactive phase. METHODS: Thirty euthyroid patients were evaluated in the inactive phase of disease with age ranging from 26 to 65 years, average of 43 ± 11,0 years, called study group and 39 individuals without Graves' ophthalmopathy with age ranging from 18 to 67 years, average of 41 ± 13,4 years, selected from the general population called control group. To evaluate the self-esteem the Rosenberg UNIFESP/EPM self-esteem scale, applied by means of an interview, was utilized. The self-esteem scores in the two studied groups were compared by means of the non-parametric Mann-Whitey test. The same test was applied to compare the obtained scores in the Graves' ophthalmopathy group considering disease severity. RESULTS: No alteration with statistical significance in Graves' ophthalmopathy patients' self-esteem was observed (P=0.057). The study group presented, on average, lower self-esteem values when compared with the control group. There was no difference of self-esteem mild and moderate-severe patients (P=0.2710). CONCLUSION: Graves' ophthalmopathy in the inactive phase did not affect the patients' self-esteem in the group studied.

Stress and autoimmune thyroid diseases.

Autoimmune thyroid diseases (AITD) are the far most common autoimmune disorders, their prevalence in Western countries exceeding 5% of the general population. In the large majority of individual cases the clinical impact of AITD is not severe, however, their widespread diffusion renders them a significant health problem. AITD are heterogeneous in their clinical presentation: the two main forms are autoimmune thyroiditis (AT) and Graves' disease (GD). Although they probably share, at least in part, a common genetic background and may occur in the same family as well as in the same individual, they are definitely two distinct diseases both in their clinical presentation and their pathophysiology. In fact, AT causes structural thyroid damage (mainly via cell-mediated immune destruction of thyroid follicular cells) which results, as a rule, in functional impairment (hypothyroidism); however, depending on clinical variants, evolution towards hypothyroidism may be very low, or thyroid function impairment occurs after an initial phase of mild thyrotoxicosis due to relatively rapid gland destruction. GD patients have hyperthyroidism, often severe, due to autoantibody-mediated thyrotropin receptor stimulation, with thyroid cell hyperplasia and hyperfunction. Such a functional heterogeneity is a key feature for the clinical management: as a matter of fact, therapy of AITD is mainly therapy of thyroid dysfunction. Moreover, since hyperthyroidism is quite early perceived by the patient as a cause of discomfort, the timing of the natural history of GD is relatively well defined; on the other hand, AT may be asymptomatic for a long time and defining its natural history in a single patient may be difficult. In some AITD patients (mainly, but not exclusively, with GD), clinical features not directly related to thyroid dysfunction, such as orbitopathy, are present. Graves' orbitopathy is probably related, at least in part, to autoantibodies directed to thyrotropin receptor; it may be, in a minority of patients, severe and sight-threatening, and represents an independent clinical problem.

[Psychological view of thyroid cancer and in hyperthyroid Graves' patients - comparative exploration]. / Porównawcze badania psychologiczne chorych z rakiem tarczycy oraz z nadczynnoscia tarczycy w przebiegu choroby Gravesa-Basedowa.

INTRODUCTION: The aim of study was the evaluation of association between psychometric factors in patients with thyroid cancer and in Graves' hyperthyroid patients. MATERIAL AND METHODS: We examined 50 patients with differentiated thyroid cancer, 42 females (84.75%), 8 males aged from 32 to 64 yr. (x +/- SD: 43 +/- 8.17 yr.) and 50 hyperthyroid patients, 45 (90%) females and 5 (10%) males corresponding aged. We used the following methods: the EAS Temperament Survey (EASD) in addition for adults, EPQ Eysenck Personality Questionnaire, Polish Abbreviated Form of the MMPI (DKO-74) and Beck's Depression Scale. We compared the scores of thyroid cancer patients and hyperthyroid patients. RESULTS: We have interpreted obtained results in both groups as similarly in: mild sense depression, high emotional control, high social dependence, ambiverssion, mild level of emotional mental balance. CONCLUSION: Results of our explorations appears great psychological similarity between differentiated thyroid patients and hyperthyroid patients.

Graves' disease: a long-term quality-of-life follow up of patients randomized to treatment with antithyroid drugs, radioiodine, or surgery.

The effects of treatment modality for Graves' disease (GD) were studied with respect to long-term quality of life and present health status. A total of 179 patients with GD were randomized during the period 1983-1990 for treatment with antithyroid drugs, radioiodine, or surgery. A 36-item Short Form Health Status Survey questionnaire and specific questions for GD were sent to patients 14-21 years after randomization. Present medical records, and clinical and laboratory status were recorded. No major significant differences in quality of life among the three treatments were observed. Compared to a large Swedish reference group, all treatment groups had significantly lower scores for vitality (p < 0.05). The Mental Component Summary was lower for both the young medical, young surgical, and the older medical group (p < 0.05). Radioiodine-treated patients had a lower General Health score. Young medical patients (<35 years) had lower Mental Health scores (p < 0.05). There was also a strong trend, which barely met statistically significance, for older surgical and radioiodine groups for lower Mental Component Summary. GD patients have, compared with a large Swedish reference population, diminished vital and mental quality of life aspects even many years after treatment. The quality-of-life scores were not different among the three treatment modalities.

Hunger-satiety signals in patients with Graves' thyrotoxicosis before, during, and after long-term pharmacological treatment.

UNLABELLED: Patients with Graves' thyrotoxicosis lose weight despite increased appetite and food intake, thus suggesting a disturbed balance between energy intake and expenditure. Underlying mechanisms are not fully elucidated. The objective of this study was to investigate whether hormonal factors, known to affect hunger/satiety, change significantly over time as pharmacological treatment turns hyperthyroidism into euthyroidism. For that purpose 11 patients with Graves' thyrotoxicosis were given thiamazole and l-thyroxine for 18-20 mo. They were investigated on three occasions: Test 1: before pharmacological therapy; Test 2: during medication; Test 3: a few months after conclusion of the pharmacological treatment. Sixteen healthy subjects were also investigated for comparison. The participants were fasted overnight. Blood samples for determination of plasma glucose and serum concentrations of free T3 and T4, TSH, albumin, cortisol, insulin, GH, IGF-1, IGFBP-1, leptin, and ghrelin were drawn in the morning from an antecubital vein. Laboratory data obtained in test 1 were statistically compared with those in tests 2 and 3. The study showed that the free T3 level declined from 42.8 +/- 4.3 pmol/L in test 1 to 6.0 +/- 0.8 pmol/L in test 2 (85 +/- 2% decline), and 5.5 +/- 0.3 pmol/L in test 3 (86 +/- 2% decline). The free T4 level fell concomitantly from 65.2 +/- 4.8 to 16.6 +/- 1.7 and 14.4 +/- 1.2 pmol/L. The glucose level was significantly higher during hyperthyroidism (test 1) than during euthyroidism (tests 2 and 3), whereas cortisol, insulin, GH, IGF-1, and leptin levels were similar. The IGFBP-1 level was initially high (48.8 +/- 8.5 microg/L in test 1), but with a relative decline in free T3 of 85 +/- 2% (test 2) the IGFBP-1 level declined by 34 +/- 13%, and with a free T3 decline of 86 +/- 2% (test 3) the binding protein fell by 39 +/- 29%. This brought about increased IGF-1 bioavailability as reflected by a rising IGF-1/IGFBP-1 ratio from 5.1 +/- 1.1 to 13.8 +/- 2.9 (p < 0.01). The ghrelin level was low (2454 +/- 304 ng/L) in test 1. It increased to 3127 +/- 397 ng/L in test 2 (p < 0.05), and to 3348 +/- 279 ng/L in test 3 (p < 0.01). CONCLUSION: Both ghrelin secretion and IGF-1 bioavailability are low in patients with untreated thyrotoxicosis, but increase markedly as pharmacotherapy makes them euthyroid. These metabolic changes may be caused by the transition of hyperthyroidism into euthyroidism rather than by the pharmacotherapy per se, since the metabolic changes prevailed also in the posttreatment period.

Mania associada ao uso de glicocorticóides para oftalmopatia de Graves: relato de caso / Mania associated with the use of glucocorticoids for Graves' ophthalmopathy: case report

O hipertireoidismo é uma síndrome clínica de hipermetabolismo caracterizada por várias manifestações sistêmicas, inclusive neuropsiquiátricas. Além do mais, a doença de Graves, uma das formas mais comuns de hipertireoidismo, pode cursar com uma forma específica de oftalmopatia. Os glicocorticóides são freqüentemente utilizados no tratamento desses sintomas oculares da doença. Por outro lado, encontra-se bem estabelecido que os corticóides podem causar complicações psiquiátricas. Relatamos um caso de uma paciente com tireotoxicose pela doença de Graves que, durante o seu acompanhamento, evoluiu com quadro compatível com síndrome maníaca associado à introdução de corticosteróide para controle da oftalmopatia. Discutimos as manifestações psiquiátricas apresentadas pela paciente assim como analisamos fatores associados ao desenvolvimento da síndrome maníaca nessa condição clínica.

Disease-specific assessment of quality of life after decompression surgery for Graves' ophthalmopathy.

PURPOSE: Graves' ophthalmopathy (GO) is an organ-specific autoimmune disease. Hydrophily of accumulated acidic mucopolysaccharides into bulbar adipose tissue leads to swelling of the eye muscles. Orbital surgical decompression is performed in severe cases of compressive optic neuropathy and severe corneal exposure or failure of steroid therapy. The study was designed to evaluate decompression surgery with respect to the clinical benefit and the patient's satisfaction by means of a disease-specific questionnaire. METHODS: The 90-item study questionnaire was distributed to 105 patients with GO who underwent orbital decompression surgery at the authors' institution. RESULTS: A total of 88% of patients stated that decompression had helped them, 80% of the interviewees would undergo decompression again, 78% were content with their eye symptoms, and 71% were satisfied with the cosmetic result of decompression. Furthermore, analysis showed a clinically relevant increase in quality of life after surgery. The correlation between the clinical endpoint proptosis at last examination and the quality of life score proved to be significant (p=0.05). CONCLUSIONS: The large majority of interviewees were satisfied with the result of the orbital decompression. These results confirmed that disfiguring proptosis is an important indication for decompression surgery.

Effects of Graves' ophthalmopathy on quality of life.

General health-related quality of life is markedly impaired in patients with Graves' ophthalmopathy (GO), and even worse than in patients with other chronic conditions like diabetes, emphysema or heart failure. A disease-specific quality-of-life questionnaire for GO has been developed, the so-called GO-QOL, consisting of two subscales: one for visual functioning (8 questions referring to limitations due to decreased visual acuity and/or diplopia) and one for appearance (8 questions referring to limitations in psychosocial functioning due to changes in appearance). The GO-QOL was found to be a valid and reliable instrument. A minimal clinically important difference (MCID) in the GO-QOL score was derived from data obtained before and after specific eye treatments. Based on the patient's opinions, changes of > or = 6 points (minor surgery) or > or = 10 points (surgical decompression, immunosuppression) are recommended as MCID. It is concluded that the GO-QOL is an useful instrument for measuring changes over time in visual functioning and appearance of GO patients. The GO-QOL is available in six languages, and can be used as a separate outcome measure in clinical studies.

[Smoking among thyroid patients]. / Palenie wsród pacjentów tyreologicznych.

UNLABELLED: The effects of cigarette smoking on the thyroid disease (Graves disease, toxic nodular goiter, toxic adenoma) have been studied for years. However, the effect of smoking on thyroid function is still controversial. OBJECTIVES: To determine the impact of cigarette smoking on the development of above-mentioned thyroid disease. PATIENTS METHODS: Study of 405 individuals with different thyroid disease. Information on thyroid disease and smoking habits was gathered by Fagerström questionnaire, and the patients' endocrinologist or general practitioner verified the diagnosis. RESULTS: The effect of smoking was more pronounced in Graves' patients than in other thyroid patients. We found out significant number of patients with toxic nodular goiter. CONCLUSIONS: Smoking is associated with an developing clinically thyroid disease--especially Graves disease. We also suggest the connection between psychological traits and smoking in this group of patients, corresponding with our previous examinations.
