Cardiometabolic Disease Burden and Steroid Excretion in Benign Adrenal Tumors : A Cross-Sectional Multicenter Study.

BACKGROUND: Benign adrenal tumors are commonly discovered on cross-sectional imaging. Mild autonomous cortisol secretion (MACS) is regularly diagnosed, but its effect on cardiometabolic disease in affected persons is ill defined. OBJECTIVE: To determine cardiometabolic disease burden and steroid excretion in persons with benign adrenal tumors with and without MACS. DESIGN: Cross-sectional study. SETTING: 14 endocrine secondary and tertiary care centers (recruitment from 2011 to 2016). PARTICIPANTS: 1305 prospectively recruited persons with benign adrenal tumors. MEASUREMENTS: Cortisol excess was defined by clinical assessment and the 1-mg overnight dexamethasone-suppression test (serum cortisol: <50 nmol/L, nonfunctioning adrenal tumor [NFAT]; 50 to 138 nmol/L, possible MACS [MACS-1]; >138 nmol/L and absence of typical clinical Cushing syndrome [CS] features, definitive MACS [MACS-2]). Net steroid production was assessed by multisteroid profiling of 24-hour urine by tandem mass spectrometry. RESULTS: Of the 1305 participants, 49.7% had NFAT (n = 649; 64.1% women), 34.6% had MACS-1 (n = 451; 67.2% women), 10.7% had MACS-2 (n = 140; 73.6% women), and 5.0% had CS (n = 65; 86.2% women). Prevalence and severity of hypertension were higher in MACS-2 and CS than NFAT (adjusted prevalence ratios [aPRs] for hypertension: MACS-2, 1.15 [95% CI, 1.04 to 1.27], and CS, 1.37 [CI, 1.16 to 1.62]; aPRs for use of ≥3 antihypertensives: MACS-2, 1.31 [CI, 1.02 to 1.68], and CS, 2.22 [CI, 1.62 to 3.05]). Type 2 diabetes was more prevalent in CS than NFAT (aPR, 1.62 [CI, 1.08 to 2.42]) and more likely to require insulin therapy for MACS-2 (aPR, 1.89 [CI, 1.01 to 3.52]) and CS (aPR, 3.06 [CI, 1.60 to 5.85]). Urinary multisteroid profiling revealed an increase in glucocorticoid excretion from NFAT over MACS-1 and MACS-2 to CS, whereas androgen excretion decreased. LIMITATIONS: Cross-sectional design; possible selection bias. CONCLUSION: A cardiometabolic risk condition, MACS predominantly affects women and warrants regular assessment for hypertension and type 2 diabetes.

Subtyping primary aldosteronism by inconclusive adrenal vein sampling: A derivation and validation study in a tertiary centre.

OBJECTIVE: Indices based on aldosterone/cortisol (A/C) concentration in the successfully cannulated adrenal vein (AV) and in the inferior vena cava (IVC) (AV/IVC) appear to be possible markers to verify the subtype of primary aldosteronism (PA) in the case of inconclusive results of adrenal vein sampling (AVS). The variability of results in previous studies encouraged us to calculate AV/IVC and adrenal A/C cutoff values that could predict the aetiology of PA. METHODS: This retrospective study included 96 patients who underwent AVS due to PA between 2015 and 2020. The derivation cohort ultimately consisted of 60 patients with bilaterally successful AVS and a clear diagnosis of unilateral or bilateral disease. Receiver operating characteristic analysis was used to find the optimal A/C and AV/IVC cutoff values predicting the subtype of PA. The validation cohort consisted of 11 patients with either unsuccessful cannulation or a borderline lateralization index (LI), those patients underwent adrenalectomy because their indices were suggestive of unilateral disease based on the derivation cohort data. RESULTS: The cutoff values of A/C ≤ 0.63 or AV/IVC ≤ 0.37 identified unaffected glands with a sensitivity of 91.2% and 97.1%, respectively, and a specificity of 90.7% and 88.4%, respectively. Unilateral ipsilateral gland involvement was characterized by A/C ≥ 3.5 or AV/IVC ≥ 3.4 with a corresponding specificity of 100%. All patients in the validation cohort achieved biochemical remission postoperatively. CONCLUSIONS: A/C and AV/IVC cutoff values could be a useful tool to determine the subtype of PA in patients with unilateral successful AVS as well as in patients with a borderline LI.

Gamma-knife radiosurgery in acromegaly: the results from the Croatian acromegaly registry.

PURPOSE: The aim of our study was to evaluate the efficacy and safety of Leksell gamma-knife radiosurgery in the treatment of residual growth hormone-secreting pituitary adenomas after the surgery. MATERIALS AND METHODS: We conducted a retrospective analysis of 23 acromegaly patients treated with gamma-knife radiosurgery between 1996 and 2019. The therapeutic success of radiosurgery was defined as IGF-1 normalization without suppressive medication (complete response) or as IGF-1 normalization with medication (partial response). RESULTS: The median follow-up was 57 (10-198) months. Complete response was achieved in 11 patients (47.8%) with actuarial remission rates of 17.4%, 26.1%, 39.1% and 47.8% at 1, 2, 4, and 7 years, respectively. The median time to complete the response was 21 (6-85) months. Partial response was achieved in another nine patients (39.1%) after a median time of 48 (6-144) months from radiosurgery. Patients who achieved complete remission had significantly lower IGF-1 levels before radiosurgery (p = 0.016) as well as smaller tumour volume (p = 0.016) and radiologically less invasive tumours (p = 0.022) in comparison to patients who did not achieve IGF-1 normalization. Tumour growth control after radiosurgery was established in all patients. During the follow-up, new hormone deficiencies were found in seven patients (30.4%) which corresponds to the incidence of one new case of hypopituitarism per 7.1 patient years. CONCLUSIONS: Gamma-knife radiosurgery offers endocrine remission and tumour growth control in a substantial proportion of patients with GH-secreting adenomas. Given the high cost of life-long medical treatment and a moderate risk of radiation-induced side effects, radiosurgery for growth hormone-secreting pituitary adenomas should be considered in all patients with residual tumours.

Open vs laparoscopic adrenalectomy for localized adrenocortical carcinoma.

OBJECTIVE: The purpose of the study was to compare the long-term outcomes of patients with localized adrenocortical carcinoma (ACC) subjected to open vs laparoscopic surgery. DESIGN: Retrospective study. PATIENTS: This retrospective study included 46 patients with the ACC ENSAT stage I-stage III of whom 23 underwent open surgery (OA group), whereas 23 were subjected to laparoscopic adrenalectomy (LA group). The main outcomes analysed in the study were differences between the OA and LA groups in recurrence-free survival (RFS) and overall survival (OS). RESULTS: Patients in OA group had larger tumours (120 [70-250] mm vs 75 [26-110] mm; P < .001), higher Ki-67 index (16 [1-65] % vs 10 [1-25] %; P = .04) and higher disease stage (P = .01) compared with the patients in the LA group. The median duration of follow-up for patients underwent OA and LA was 51 (12-174) and 53 (5-127) months, respectively. Eight patients (5 OA and 3 LA) experienced recurrent disease, whereas six patients (3 OA and 3 LA) died during follow-up. No differences in RFS and OS were found between patients who underwent open or laparoscopic surgery. CONCLUSION: The study demonstrated that in patients with localized ACC and without invasion of extra-adrenal tissues, LA is a plausible treatment option in terms of RFS and OS. However, our results are limited to referral centres with large experience in the management of patients with ACC and may not necessarily apply to nonspecialized centres.

Hypopituitarism after gamma knife radiosurgery for pituitary adenoma.

PURPOSE: The aim of the study was to investigate the incidence of and risk factors for hypopituitarism after gamma knife radiosurgery (GKRS) for pituitary adenoma. MATERIALS AND METHODS: We conducted a retrospective analysis of the pituitary function of 90 patients who underwent GKRS for pituitary adenoma at the University Hospital Centre Zagreb between 2003 and 2014. Twenty seven of them met the inclusion criteria and the others were excluded from the study due to pituitary insufficiency which was present before GKRS. Eighteen patients had non-functioning and 9 patients had secretory adenomas. Median patients' age was 56 years (24-82). GKRS was performed using the Leksell gamma knife Model C. The median prescription radiation dose was 20 Gy (15-25) and the median tumor volume size was 3.4 cm3 (0.06-16.81). New onset hypopituitarism was defined as a new deficit of one of the three hormonal axes (corticotroph, thyreotroph, or gonadotroph) ≥3 months following GKRS. SPSS was used for statistical analysis, with the significance level at P<0.05. RESULTS: During the median follow-up period of 72 months (range 6-144), 30% of patients developed new hypopituitarism after GKRS. This corresponds to incidence of one new case of hypopituitarism per 15 patient-years. Age, gender, tumor function, tumor volume, suprasellar extension, prescription dose of radiation, as well as dose-volume to the pituitary gland, stalk and hypothalamus were not predictive factors for the development of hypopituitarism. CONCLUSIONS: In our cohort of patients with pituitary tumors who underwent GKRS, 30% developed new hypopituitarism during the follow-up period.

Fertility and sexual activity in patients with Triple A syndrome.

Objective: Triple A syndrome, caused by autosomal recessively inherited mutations in the AAAS gene is characterized by alacrima, achalasia, adrenal insufficiency, and neurological impairment. To the best of our knowledge, no patients of both sexes have been reported to have offspring. Our aim was to assess the causes of infertility in male patients with this multisystemic syndrome, and to present a female patient that spontaneously conceived a child. Design: Cross-sectional study. Methods: Six males aged 19-48 years were included. Gonadotropins, testosterone, DHEAS, androstenedione, inhibin B, anti-Mullerian hormone measurements and testicular ultrasound were performed. Results: All six male patients had impaired general health and neurological symptoms including erectile and ejaculatory dysfunction. None of them had an offspring. The only demonstrated cause of infertility in our male patients was erectile and ejaculatory dysfunction which precludes sexual intercourse. Our patients had normal libido but were sexually abstinent. Except for low adrenal androgen levels, the concentrations of all measured hormones as well as testicular ultrasound were normal which may indicate the possibility of spermatogenesis in male patients with triple A syndrome. Little is known about fertility in female patients, but based on our observations spontaneous pregnancies seem to be possible. Conclusion: Our results contribute to still scarce knowledge on fertility in patients with Triple A syndrome and as well represents a foundation for further research on causes of infertility and possible treatment options.

Diagnostic Performance of 99mTc-Sestamibi SPECT/CT and 18F-Choline PET/CT in Locating Hyperfunctioning Parathyroid Glands in Patients with Primary Hyperparathyroidism.

OBJECTIVE: This study aimed to assess the diagnostic performance of 99mTc-sestamibi SPECT/CT and 18F-choline PET/CT in detecting hyperfunctioning parathyroid glands in patients undergoing surgery for primary hyperparathyroidism (PHPT). METHODS: A retrospective analysis was conducted on patients who underwent PHPT-related surgery between April 2019 and May 2022. The study focused on patients undergoing either 99mTc-sestamibi SPECT/CT (81 patients) or 18F-choline PET/CT (33 patients) scans before surgery to pinpoint hyperfunctioning parathyroid gland(s). In the majority of patients, 18F-choline PET/CT was performed after negative or inconclusive findings on 99mTc-sestamibi SPECT/CT. Pathohistological reports were utilized as the reference standard for evaluating the accuracy of the imaging findings. RESULTS: The study encompassed 83 patients (70 females, 84.3%) with an average age of 57.2 years (24-80 years). The pathohistological analysis identified a total of 98 glands. In a per-lesion analysis, the detection rate of 99mTc-sestamibi SPECT/CT was 57% (95% CI 45.3-68.1), while the detection rate of 18F-choline PET/CT was 90.3% (95% CI 74.3-98.0). CONCLUSION: The results of our study showed the significant usefulness of 18F-choline PET/CT in patients with negative or inconclusive results of 99mTc-sestamibi SPECT/CT in accurately locating hyperfunctioning parathyroid glands in PHPT patients.

The Value of Local Therapies in Advanced Adrenocortical Carcinoma.

International guidelines recommend local therapies (LTs) such as local thermal ablation (LTA; radiofrequency, microwave, cryoablation), transarterial (chemo)embolisation (TA(C)E), and transarterial radioembolisation (TARE) as therapeutic options for advanced adrenocortical carcinoma (ACC). However, the evidence for these recommendations is scarce. We retrospectively analysed patients receiving LTs for advanced ACC. Time to progression of the treated lesion (tTTP) was the primary endpoint. The secondary endpoints were best objective response, overall progression-free survival, overall survival, adverse events, and the establishment of predictive factors by multivariate Cox analyses. A total of 132 tumoural lesions in 66 patients were treated with LTA (n = 84), TA(C)E (n = 40), and TARE (n = 8). Complete response was achieved in 27 lesions (20.5%; all of them achieved by LTA), partial response in 27 (20.5%), and stable disease in 38 (28.8%). For the LTA group, the median tTTP was not reached, whereas it was reached 8.3 months after TA(C)E and 8.2 months after TARE (p < 0.001). The median time interval from primary diagnosis to LT was >47 months. Fewer than four prior therapies and mitotane plasma levels of >14 mg/L positively influenced the tTTP. In summary, this is one of the largest studies on LTs in advanced ACC, and it demonstrates a very high local disease control rate. Thus, it clearly supports the guideline recommendations for LTs in these patients.

Hypercoagulable state in Cushing's syndrome is reversible following remission.

OBJECTIVE: Hypercoagulability is a commonly described complication in patients with Cushing's syndrome (CS). The aim of this study was to assess the long-term effects of surgical remission from CS on serum levels of coagulation and fibrinolytic markers. DESIGN AND METHODS: Eighteen patients with active CS (16 women, 2 men; age: 38.6 ± 13.7 years) were enrolled in the study. We measured serum levels of coagulation and fibrinolytic markers during active CS and 6 months after remission. The control group comprised 18 age- and sex-matched healthy individuals. RESULTS: Six months after remission from CS, patients had lower levels of factors II (P < 0.001), V (P = 0.02), XI (P = 0.04) and XII (P < 0.001), protein C (P < 0.001), protein S (P = 0.002), antithrombin (P = 0.03), antithrombin Ag (P = 0.008), plasminogen (P = 0.03) and C1 inhibitor (P = 0.001), and aPTT was longer than at enrollment (P = 0.001). Levels of PAI-1 and factors VII, VIII and IX tended to normalize, but there were no significant differences in these parameters before and after surgery, nor were differences found in haemostatic and fibrinolytic markers between the patients in remission and control individuals, except for factor XII (P = 0.02) and protein C (P = 0.004), which were lower among patients in remission. CONCLUSION: Six months after remission from CS, patients' risk of thromboembolism is comparable to that of healthy individuals.

Medical treatment of acromegaly-experience from the Croatian acromegaly registry.

PURPOSE: The aim of this study was to review therapeutic outcomes of the medical treatment of patients with acromegaly based on real-world data from the Croatian Acromegaly Registry. METHODS: In this retrospective study we investigated 163 patients (101 female, 62 male, age at diagnosis 47.2 ± 13.4 years) treated between 1990 and 2020, of which 53 were treated medically (32.5%). The duration of follow-up was 115.8 ± 304.4 months. The remission rate after the pituitary surgery was achieved in 66.5% (n = 105/158; 5 patients refused surgery). Patients who did not achieve disease remission or had a relapse during follow-up (n = 2), underwent reoperation (n = 18/60, 30%) and/or radiotherapy (n = 33/60, 55%) and/or medical treatment (n = 53/60, 88.3%). One patient refused further treatment after the failure of the first pituitary surgery. RESULTS: Out of 53 patients treated with medical therapy, monotherapy was used in 34 (64.2%) and combination therapy in 19 (35.8%) patients. Remission (IGF-I < 1.2 upper limit of normal, ULN) was achieved in 51 patients (96.2%). Out of 53 patients, 21 (39.6%) were treated with first-generation somatostatin receptor ligand (SRL-1) monotherapy, 10 (18.9%) with dopamine agonist (DA) monotherapy, one (1.9%) with pegvisomant monotherapy, 13 (24.4%) with a combination of SRL-1 and DA, three (5.7%) with a combination of SRL-1, DA and pegvisomant, two (3.8%) with a combination of second-generation somatostatin receptor ligand (SRL-2), DA and pegvisomant and in one (1.9%) temozolomide was added on top of SRL-1 and DA. Two patients currently have active disease, both on SRL-1 monotherapy, of whom one is non-adherent to the treatment. Radiotherapy was applied to 27 (50.9%) patients on medical therapy. CONCLUSION: Our results indicate that almost all patients with active acromegaly after pituitary surgery can achieve biochemical control with medical treatment.

Adjuvant mitotane versus surveillance in low-grade, localised adrenocortical carcinoma (ADIUVO): an international, multicentre, open-label, randomised, phase 3 trial and observational study.

BACKGROUND: Adjuvant treatment with mitotane is commonly used after resection of adrenocortical carcinoma; however, treatment remains controversial, particularly if risk of recurrence is not high. We aimed to assess the efficacy and safety of adjuvant mitotane compared with surveillance alone following complete tumour resection in patients with adrenocortical carcinoma considered to be at low to intermediate risk of recurrence. METHODS: ADIUVO was a multicentre, open-label, parallel, randomised, phase 3 trial done in 23 centres across seven countries. Patients aged 18 years or older with adrenocortical carcinoma and low to intermediate risk of recurrence (R0, stage I-III, and Ki67 ≤10%) were randomly assigned to adjuvant oral mitotane two or three times daily (the dose was adjusted by the local investigator with the target of reaching and maintaining plasma mitotane concentrations of 14-20 mg/L) for 2 years or surveillance alone. All consecutive patients at 14 study centres fulfilling the eligibility criteria of the ADIUVO trial who refused randomisation and agreed on data collection via the European Network for the Study of Adrenal Tumors adrenocortical carcinoma registry were included prospectively in the ADIUVO Observational study. The primary endpoint was recurrence-free survival, defined as the time from randomisation to the first radiological evidence of recurrence or death from any cause (whichever occurred first), assessed in all randomly assigned patients by intention to treat. Overall survival, defined as time from the date of randomisation to the date of death from any cause, was a secondary endpoint analysed by intention to treat in all randomly assigned patients. Safety was assessed in all patients who adhered to the assigned regimen, which was defined by taking at least one tablet of mitotane in the mitotane group and no mitotane at all in the surveillance group. The ADIUVO trial is registered with ClinicalTrials.gov, NCT00777244, and is now complete. FINDINGS: Between Oct 23, 2008, and Dec 27, 2018, 45 patients were randomly assigned to mitotane and 46 to surveillance alone. Because the study was discontinued prematurely, 5-year recurrence-free and overall survival are reported instead of recurrence-free and overall survival as defined in the protocol. 5-year recurrence-free survival was 79% (95% CI 67-94) in the mitotane group and 75% (63-90) in the surveillance group (hazard ratio 0·74 [95% CI 0·30-1·85]). Two people in the mitotane group and five people in the surveillance group died, and 5-year overall survival was not significantly different (95% [95% CI 89-100] in the mitotane group and 86% [74-100] in the surveillance group). All 42 patients who received mitotane had adverse events, and eight (19%) discontinued treatment. There were no grade 4 adverse events or treatment-related deaths. INTERPRETATION: Adjuvant mitotane might not be indicated in patients with low-grade, localised adrenocortical carcinoma considering the relatively good prognosis of these patients, and no significant improvement in recurrence-free survival and treatment-associated toxicity in the mitotane group. However, the study was discontinued prematurely due to slow recruitment and cannot rule out an efficacy of treatment.

[Croatian Society of Endocrinology guidelines for the diagnosis and treatment of acromegaly]. / Smjernice Hrvatskoga endokrinoloskog drustva za dijagnostiku i lijecenje akromegalije.

The working group of the Croatian Society of Endocrinology met in September 2011 to discuss the diagnostic and therapeutic dilemmas in patients with acromegaly. The group comprised 9 pituitary specialists including endocrinologists, neurosurgeons, and medical biochemistry specialist. After a critical analysis of published scientific papers the group has developed guidelines for the diagnosis and treatment of acromegaly.

Hypothalamic-pituitary-adrenal axis recovery after treatment of Cushing's syndrome.

After successful treatment for Cushing's syndrome (CS), secondary adrenal insufficiency develops as a result of the prior suppression of the hypothalamic-pituitary-adrenal (HPA) axis by excess cortisol in the body. Until the recovery of the HPA axis, glucocorticoid replacement therapy is required to enable normal functioning of the body and prevent adrenal crisis. Significant variation in the median time of recovery of the HPA axis is found in various cohorts of CS patients ranging from several weeks to years. Despite the use of physiological glucocorticoid replacement, after cure for CS, patients often experience symptoms of glucocorticoid withdrawal syndrome (GWS). The optimal glucocorticoid regimen to reduce GWS needs to be established and requires an individualized approach aiming to avoid overtreatment at one side and minimize the risk of undertreatment and possible adrenal crisis and GWS on the other side.

The Effect of Surgeon Expertise on the Outcome of Patients with Adrenocortical Carcinoma.

Complete surgical removal of adrenocortical carcinoma (ACC) represents the only chance of long-term cure. In this study, we compared the long-term outcomes of ACC patients depending on whether they had adrenal surgery performed in a high-volume (HVC) or in a low-volume (LVC) center. This retrospective study included 49 patients from the Croatian ACC Registry with the European Network for the Study of Adrenal Tumors (ENSAT) stage I-III ACC, of which 35 underwent surgery in a HVC whereas 14 of them were operated in one of the LVCs. Patients operated in the LVCs had a significantly higher rate of ACC recurrence (57.1% vs. 22.9%; p = 0.02). Accordingly, RFS was significantly longer in patients operated on in HVC (p = 0.04). The difference in RFS remained significant after controlling for age, gender, tumor size, Ki-67 index, Weiss score, and type of surgery (HR 4.55; 95% CI 1.16-17.88; p = 0.03). In addition, there is a tendency towards longer DSS in patients in the HVC group compared to those in the LVC group (p = 0.05). These results point to the centralization of adrenal surgery as a key prerequisite for improving the outcomes of ACC patients.

Age-dependent and sex-dependent disparity in mortality in patients with adrenal incidentalomas and autonomous cortisol secretion: an international, retrospective, cohort study.

BACKGROUND: The association between cortisol secretion and mortality in patients with adrenal incidentalomas is controversial. We aimed to assess all-cause mortality, prevalence of comorbidities, and occurrence of cardiovascular events in uniformly stratified patients with adrenal incidentalomas and cortisol autonomy (defined as non-suppressible serum cortisol on dexamethasone suppression testing). METHODS: We conducted an international, retrospective, cohort study (NAPACA Outcome) at 30 centres in 16 countries. Eligible patients were aged 18 years or older with an adrenal incidentaloma (diameter ≥1 cm) detected between Jan 1, 1996, and Dec 31, 2015, and availability of a 1 mg dexamethasone suppression test result from the time of the initial diagnosis. Patients with clinically apparent hormone excess, active malignancy, or follow-up of less than 36 months were excluded. Patients were stratified according to the 0800-0900 h serum cortisol values after an overnight 1 mg dexamethasone suppression test; less than 50 nmol/L was classed as non-functioning adenoma, 50-138 nmol/L as possible autonomous cortisol secretion, and greater than 138 nmol/L as autonomous cortisol secretion. The primary endpoint was all-cause mortality. Secondary endpoints were the prevalence of cardiometabolic comorbidities, cardiovascular events, and cause-specific mortality. The primary and secondary endpoints were assessed in all study participants. FINDINGS: Of 4374 potentially eligible patients, 3656 (2089 [57·1%] with non-functioning adenoma, 1320 [36·1%] with possible autonomous cortisol secretion, and 247 [6·8%] with autonomous cortisol secretion) were included in the study cohort for mortality analysis (2350 [64·3%] women and 1306 [35·7%] men; median age 61 years [IQR 53-68]; median follow-up 7·0 years [IQR 4·7-10·2]). During follow-up, 352 (9·6%) patients died. All-cause mortality (adjusted for age, sex, comorbidities, and previous cardiovascular events) was significantly increased in patients with possible autonomous cortisol secretion (HR 1·52, 95% CI 1·19-1·94) and autonomous cortisol secretion (1·77, 1·20-2·62) compared with patients with non-functioning adenoma. In women younger than 65 years, autonomous cortisol secretion was associated with higher all-cause mortality than non-functioning adenoma (HR 4·39, 95% CI 1·93-9·96), although this was not observed in men. Cardiometabolic comorbidities were significantly less frequent with non-functioning adenoma than with possible autonomous cortisol secretion and autonomous cortisol secretion (hypertension occurred in 1186 [58·6%] of 2024 patients with non-functioning adenoma, 944 [74·0%] of 1275 with possible autonomous cortisol secretion, and 179 [75·2%] of 238 with autonomous cortisol secretion; dyslipidaemia occurred in 724 [36·2%] of 1999 patients, 547 [43·8%] of 1250, and 123 [51·9%] of 237; and any diabetes occurred in 365 [18·2%] of 2002, 288 [23·0%] of 1250, and 62 [26·7%] of 232; all p values <0·001). INTERPRETATION: Cortisol autonomy is associated with increased all-cause mortality, particularly in women younger than 65 years. However, until results from randomised interventional trials are available, a conservative therapeutic approach seems to be justified in most patients with adrenal incidentaloma.

Multiple Metatarsal Fractures: The First Manifestation of Cushing's Disease-A Case Report.

Cushing's syndrome is an uncommon clinical condition most frequently presenting with central obesity, facial rounding, proximal muscle weakness, and skin thinning. The objective of this case report is to highlight an unusual presentation of Cushing's syndrome. A 35-year-old woman presented to the orthopedic clinic with a 1-year history of foot pain without any history of trauma. Radiography of the foot showed multiple metatarsal fractures. Evaluation for secondary causes of reduced bone strength revealed that the patient had Cushing's disease, although other typical signs and symptoms were not remarkable. It can be concluded that Cushing's syndrome should always be included in the differential diagnosis of foot fracture without any evidence of trauma.

Approach to patients with European Network for the Study of Adrenal Tumor stages I and II adrenocortical carcinomas.

PURPOSE OF REVIEW: Adrenocortical carcinoma (ACC) is a rare tumor with variable prognosis depending mostly on the disease stage and tumor grade. The staging system proposed by the European Network for the Study of Adrenal Tumors has a reliable prognostic potential and defines ACC stages I-IV. Due to the absence of extraadrenal tissue invasion, patients with stage I-II have a lower recurrence rate and better prognosis. This article elaborates on the current understanding of the clinical approach to this group of patients. RECENT FINDINGS: Concerning the treatment, complete surgical resection of the tumor provides the only chance for cure. However, even after tumor removal, the risk of recurrence remains high and the main predictors of recurrence include tumor stage, grade (measured by Ki-67 proliferative index), and the tumor resection status. Adjuvant mitotane and/or adjuvant radiotherapy should be considered in patients with high risk of recurrence taking into account potential harmful effects of such treatment. Accordingly, careful selection of patients who may benefit from adjuvant treatment is of the utmost importance both for improving disease outcome and for avoiding potential overtreatment in patients who are at low risk of disease recurrence. SUMMARY: Many aspects of the management of patients with ACC stages I and II are not entirely evidence-based, and treatment decisions rely mostly on expert opinions and data from retrospective studies. Therefore, the treatment of these patients should be restricted to specialized centers with high expertise in ACC.

Health-related quality of life among patients with postmenopausal osteoporosis treated with weekly and monthly bisphosphonates.

OBJECTIVE: The present study was designed to assess the effect of monthly ibandronate on health-related quality of life (HR-QoL) in patients with postmenopausal osteoporosis previously treated with weekly bisphosphonates. METHODS: HR-QoL was assessed by Euroqol (EQ-5D) and Osteoporosis Targeted Quality of Life (OPTQoL) questionnaires. RESULTS: The EQ-5D questionnaire showed significant improvement associated with ibandronate treatment, occurring in mobility (p < 0.01), usual activity (p < 0.01), pain/discomfort (p < 0.05), and anxiety/depression (p < 0.05). In addition, ibandronate treatment considerably improved patients' perceived health on a visual analog scale (p < 0.001). For the OPTQoL questionnaire, patients reported less physical difficulty (p < 0.001), fewer adaptations in their lives (p < 0.001), and less fear (p < 0.001) with ibandronate than with weekly bisphosphonates. CONCLUSION: The study demonstrated that patients who were transferred from weekly bisphosphonates to a monthly ibandronate experienced improved HR-QoL.

Adrenal incidentalomas are tumours of adrenal glands discovered during diagnostic workup for other clinical condition unrelated to adrenal glands. Improvement in imaging techniques and their widespread use in everyday practice have increased detection of adrenal incidentalomas making their management one of the most important challenges of modern endocrinology. Based on the relevant medical literature and guidelines of other international societies a panel of Croatian leading experts in adrenal gland disorders provide practical recommendations for the diagnostics and treatment of adrenal incidentaloma.

Early Basal Cortisol Level as a Predictor of Hypothalamic-Pituitary-Adrenal (HPA) Axis Function After Pituitary Tumor Surgery.

PURPOSE: The purpose of this study was to evaluate the clinical relevance of the early postoperative basal cortisol level in assessing the postoperative hypothalamic-pituitary-adrenal (HPA) axis function after pituitary tumor surgery. METHODS: We performed a prospective observational study that enrolled 83 patients operated for pituitary adenoma or other sellar lesions at the University Hospital Center Zagreb between December 2013 and April 2017 (44 nonfunctioning pituitary adenomas, 28 somatotropinomas, 5 craniopharyngiomas, 2 prolactinomas resistant to medical therapy and 4 other lesions - Rathke's cleft cyst, arachnoid cyst, chondroma and gangliocytoma). Exclusion criteria were Cushing's disease, chronic therapy with glucocorticoids prior to surgery and preoperative adrenal insufficiency. Early postoperative basal cortisol levels (measured on the second postoperative day) and the Synacthen stimulation test (performed 3 months after the surgery with the peak cortisol level of>500 nmol/L considered as a normal response) were analyzed to assess HPA axis function during follow-up. RESULTS: ROC analysis showed a cut-off of the basal cortisol level of ≥300 nmol/L measured on the second postoperative day to predict normal postoperative HPA axis function with the sensitivity of 92.31%, specificity of 87.14% and positive predictive value of 57.14%. CONCLUSION: The basal cortisol level on the second postoperative day is a valuable tool to predict integrity of the HPA axis after pituitary tumor surgery. Our data suggest that the cortisol level of ≥300 nmol/L accurately predicts adrenal sufficiency and that in these patients glucocorticoid therapy can be withdrawn.
