    Abstract Context: Patients with amiodarone-induced thyrotoxicosis (AIT) often receive initial therapy for thyrotoxicosis in several different medical settings before admission to a referral center.
    Objective: This work aimed to determine whether first-line medical therapy (ie, therapies for thyrotoxicosis at first diagnosis of AIT) affects the outcome of AIT patients.
    Methods: A single-center historical-prospective cohort study was conducted on 313 AIT patients. Clinical and biochemical data were collected at first diagnosis, at a referral center, and during the course of AIT. Primary outcomes were cardiovascular (CV) events and hospitalizations. First-line therapies were considered appropriate when they included glucocorticoids for type 2 AIT and methimazole for type 1 AIT at the approved dose, either alone (optimal medical therapy, OMT) or in combination (right-dose combination therapy, RCT). Other therapies were considered not appropriate, including no therapy. Duration of exposure to thyrotoxicosis was the time from first diagnosis of AIT to its remission.
    Results: A total of 34.5% patients received appropriate therapies (28.1% OMT, 6.4% RCT), whereas the remaining (65.5%) received inappropriate therapies. CV events and hospitalizations were more frequent in patients who received inappropriate therapies (33.2% vs 4.5%, and 24.9% vs 6.5%, respectively; P < .0001 for both). Appropriate therapies reduced serum thyroid hormone concentrations (P = .018) from first diagnosis to referral, unlike the inappropriate therapies. The duration of exposure to thyrotoxicosis was longer in patients receiving inappropriate therapies and was a risk factor for arrhythmias (hazard ratio [HR] 1.004; P = .0008), major acute CV events (HR 1.004; P = .020), and hospitalizations (HR 1.006; P < .0001).
    Conclusion: The first medical therapy of AIT influences the exposure time to thyrotoxicosis and the occurrence of CV events and hospitalizations.

    Abstract Purpose: The aim of this study was to examine the probability of achieving acromegaly disease control according to several patient-, disease- and treatment-related factors longitudinally.
    Methods: We analyzed data from ACROSTUDY, an open-label, noninterventional, post-marketing safety surveillance study conducted in 15 countries. A total of 1546 patients with acromegaly and treated with pegvisomant, with available information on baseline IGF-1 level, were included. Factors influencing IGF-1 control were assessed up to 10 years of follow-up by mixed-effects logistic regression models, taking into account changing values of covariates at baseline and at yearly visits. Twenty-eight anthropometric, clinical and treatment-related covariates were examined through univariate and multivariate analyses. We tested whether the probability of non-control was different than 0.50 (50%) by computing effect sizes (ES) and the corresponding 95% CI.
    Results: Univariate analysis showed that age <40 years, normal or overweight, baseline IGF-1 <300 µg/L or ranged between 300 and 500 µg/L, and all pegvisomant dose <20 mg/day were associated with a lower probability of acromegaly uncontrol. Consistently, in multivariate analyses, the probability of uncontrolled acromegaly was influenced by baseline IGF-1 value: patients with IGF-1 <300 µg/L had the lowest risk of un-controlled acromegaly (ES = 0.29, 95% CI: 0.23-0.36). The probability of acromegaly uncontrol was also lower for values 300-500 µg/L (ES = 0.37, 95% CI: 0.32-0.43), while it was higher for baseline IGF-1 values ≥700 µg/L (ES = 0.58, 95% CI: 0.53-0.64).
    Conclusion: Baseline IGF-l levels were a good predictor factor for long-term acromegaly control. On the contrary, our data did not support a role of age, sex, BMI and pegvisomant dose as predictors of long-term control of acromegaly.
    Significance statement: Among factors that could influence and predict the efficacy of pegvisomant therapy in controlling acromegaly, a central role of baseline IGF-1 values on the probability of achieving a biochemical control of acromegaly during the treatment with pegvisomant was identified, in a real-life setting.

    Abstract Fewer than 100 cases of amiodarone-induced thyrotoxicosis (AIT) managed surgically have been reported worldwide. This study aims to assess the outcome of thyroidectomy under general anesthesia in a relatively large case series. A retrospective analysis of the clinical records of 53 patients who underwent thyroidectomy for AIT between 1995 and 2019 was conducted. There were 48 (90%) males and 5 females with an average age of 63.7 years. Type 1 and 2 AIT were present in 35 (66%) and 18 (34%) of patients, respectively. The mean preoperative ejection fraction (EF) was 45 ± 13%. Salvage surgery was performed in 6 (11%) patients due to decompensating heart failure and/or malignant arrhythmias. 35 (66%) patients underwent urgent surgery due to a predicted late response to medical therapy and/or the need to discontinue it. Elective surgery was performed in the remainder. A considerable improvement in mean EF occurred 12 months post-surgery (44% vs. 49%; p < 0.001). The overall survival rate following thyroidectomy was 96% at 12 months, and 83% at 5 years. No survival differences were observed based on systolic function. Cardiac-specific mortality was 11%, and these patients demonstrated a considerably shorter survival post-surgery compared to those who died of a non-cardiac cause (27 ± 18 vs. 77.5 ± 54 months; p < 0.05). Total thyroidectomy can be safely performed under general anesthesia despite severe cardiac disease. It considerably improves cardiac function and confers a survival advantage. Therefore, it should be considered early in the treatment plan of select cases.

    Title translation Amiodarone-induced thyrotoxicosis.
    Abstract Amiodarone-induced thyroid dysfunction occurs in about 15-20% of patients under amiodarone therapy. Amiodarone-induced hypothyroidism (AIH) can develop in patients with an apparently normal thyroid gland or in those with an underlying chronic autoimmune thyroiditis. On a clinical ground, AIH is not challenging and can be easily treated with L-thyroxine therapy. Amiodarone-induced thyrotoxicosis (AIT) can occur in patients with (AIT 1) or without (AIT 2) an underlying thyroid disease. AIT 1 is a true iodine-induced hyperthyroidism occurring in patients with an underlying thyroid autonomy while AIT 2 is a drug-induced destructive thyroiditis. According to the different pathogenetic mechanism, AIT 2 is treated with glucocorticoids while AIT 1 usually responds to thionamides. Thyroidectomy should be considered when AIT represents an imminent risk for cardiac conditions, when patients require a prompt resolution of thyrotoxicosis or when they do not respond to the medical therapy. An effective collaboration between cardiologists and endocrinologists is crucial in each part of the management of AIT patients, including the evaluation of cardiological conditions with regard to thyroid hormone excess and whether, or not, it is necessary to continue amiodarone therapy.

    Abstract Treatment with amiodarone is associated with changes in thyroid function tests, but also with thyroid dysfunction (amiodarone-induced hypothyroidism, AIH, and amiodarone-induced thyrotoxicosis, AIT). Both AIH and AIT may develop in apparently normal thyroid glands or in the presence of underlying thyroid abnormalities. AIH does not require amiodarone withdrawal, and is treated with levothyroxine replacement if overt, whereas subclinical forms may be followed without treatment. Two main types of AIT are recognized: type 1 AIT (AIT 1), a form of iodine-induced hyperthyroidism occurring in nodular goitres or latent Graves disease, and type 2 AIT (AIT 2), resulting from destructive thyroiditis in a normal thyroid gland. Mixed/indefinite forms exist due to both pathogenic mechanisms. AIT 1 is best treated with thionamides that may be combined for a few weeks with sodium perchlorate to make the thyroid gland more sensitive to thionamides. AIT 2 is treated with oral glucocorticoids. Once euthyroidism has been restored, AIT 2 patients are followed up without treatment, whereas AIT 1 patients should be treated with thyroidectomy or radioiodine. Mixed/indefinite forms of AIT are treated with thionamides. Oral glucocorticoids can be added from the beginning if a precise diagnosis is uncertain, or after a few weeks if response to thionamides alone is poor. The decision to continue or to stop amiodarone in AIT should be individualized in relation to cardiovascular risk stratification and taken jointly by specialist cardiologists and endocrinologists. In the presence of rapidly deteriorating cardiac conditions, emergency thyroidectomy may be required for all forms of AIT.

    Abstract Objective: Acromegaly is associated with somatic disfigurements which impair self-perception of well-being and quality of life. Nowadays limited data are available on the interplay between hormonal excess and psychological discomfort. The study aimed at investigating the psychological profile, sleep quality, sexual function, cognitive functions, and quality of life in acromegaly.
    Methods: in 223 acromegaly patients from five referral centres global psychological profile, sleep quality, sexual function, cognitive function, and quality of life were investigated.
    Results: depression was found in 30% of patients, and anxiety in two-thirds, together with severe discomfort in body image mainly in women. Obstructive sleep apnea syndrome (OSAS)risk and sleep disorders were found in >50% of patients, and daily sleepiness in 20%. Sexual dysfunction was reported in most patients, with the most severe impairment in women. Cognitive functions were compromised in 10% of cases. Disease duration, patient age and gender were the main determinants of such psychological effects. Depression (p=0.047), somatic affective mood lowering (p=0.021), state (p<0.001) and trait (p=0.013) anxiety, and body image distortion at Body Uneasiness Test (BUT) A (p<0.001) and B (p=0.006) were significantly worsened in patients <45 years, and slightly worsen in those diagnosed <2 years before. International Index for Erectile Function (IIEF)-15 (p<0.001) and Female Sexual Function Index (FSFI) (p<0.001) scores were significantly worsened in patients >64 years and slightly worsened in those diagnosed >10 years before, particularly in presence of cardiometabolic and respiratory complications. Cognitive symptoms were slightly worsened in older patients and in those with long disease.
    Conclusions: Acromegaly is associated with a relevant impairment of psychological profile persisting despite remission and long-term medical treatment.
