RESUMO
OBJECTIVE: Acromegaly is associated with increased morbidity and mortality if left untreated. The therapeutic options include surgery, medical treatment, and radiotherapy. Several guidelines and recommendations on treatment algorithms and follow-up exist. However, not all recommendations are strictly evidence-based. To evaluate consensus on the treatment and follow-up of patients with acromegaly in the Nordic countries. METHODS: A Delphi process was used to map the landscape of acromegaly management in Denmark, Sweden, Norway, Finland, and Iceland. An expert panel developed 37 statements on the treatment and follow-up of patients with acromegaly. Dedicated endocrinologists (n = 47) from the Nordic countries were invited to rate their extent of agreement with the statements, using a Likert-type scale (1-7). Consensus was defined as ≥80% of panelists rating their agreement as ≥5 or ≤3 on the Likert-type scale. RESULTS: Consensus was reached in 41% (15/37) of the statements. Panelists agreed that pituitary surgery remains first line treatment. There was general agreement to recommend first-generation somatostatin analog (SSA) treatment after failed surgery and to consider repeat surgery. In addition, there was agreement to recommend combination therapy with first-generation SSA and pegvisomant as second- or third-line treatment. In more than 50% of the statements, consensus was not achieved. Considerable disagreement existed regarding pegvisomant monotherapy, and treatment with pasireotide and dopamine agonists. CONCLUSION: This consensus exploration study on the management of patients with acromegaly in the Nordic countries revealed a relatively large degree of disagreement among experts, which mirrors the complexity of the disease and the shortage of evidence-based data.

Prolactin has many physiological effects and seems to be involved in the human quality of life and well-being. The aim of this study was to describe health related quality of life, fatigue and daytime sleepiness in women with untreated hyperprolactinemia. In total 32 women (mean age 37.0±10.9 years) with verified hyperprolactinemia completed a questionnaire including questions on fatigue, measured with the Swedish version of the Fatigue Impact Scale (FIS), propensity to fall in sleep, measured with the Swedish version of the Epworth Sleepiness Scale (ESS), and Health related quality of life (HRQoL), measured by the Short-Form-36 scale (SF-36). For comparison Swedish normative data were used. The women were also interviewed regarding different symptoms related to hyperprolactinemia and the answers were analyzed using qualitative content analysis. HRQoL, as measured with SF-36, was significantly lower in all dimensions, except in physical function, compared to the Swedish reference population. Total FIS was 54.3 (41.1) and mean score on the ESS was 8.7 (4.2) indicating increased fatigue and deterioration in night sleep. The women felt very tired, and several of them rarely felt rested in the morning. The restless night sleep and the fatigue during the daytime got them to feel feeble and sometimes to find it difficult to concentrate, which affected both their mood and life in general. Women diagnosed with hyperprolactinemia reported deterioration in night sleep, increased rate of fatigue, and a reduced health related quality of life in comparison with the reference population.

OBJECTIVE: Rathke's cleft cysts are benign, embryological remnants in the pituitary gland. The majority of them are small and asymptomatic but a few may become large, and cause mass effects, pituitary hormone deficiencies and visual impairment. Recommendations for the follow-up of Rathke's cleft cysts vary since data on the natural history are sparse. PATIENTS AND DESIGN: Data at diagnosis and at 1, 5 and 10 years for patients with a Rathke's cleft cyst (434 at diagnosis, 317 females) were retrieved from the Swedish Pituitary Registry. Cysts ≤3 mm in diameter were excluded from the study. MEASUREMENTS: Data included demographics, cyst size, pituitary function, visual defects and surgery. RESULTS: The mean age at diagnosis was 45 years. In patients with cysts <10 mm in diameter (n = 204) 2.9% had pituitary hormone deficiencies and 2% had visual field impairments. Cyst size did not progress during the 5 years. Cysts with a diameter of ≥10 mm that were not operated (n = 174) decreased in size over the years (p < .01). Pituitary hormone deficiencies and visual impairments were more frequent (18% and 5.7%, respectively) but were stable over time. Transphenoidal surgery was performed in 56 patients of whom 51 underwent surgery before the 1-year follow-up. The mean cyst diameter at diagnosis was 18 mm (range: 9â30 mm), 36% had pituitary hormone deficiency, 45% had visual field defects and 20% had impaired visual acuity. One year after surgery 60% had no cyst remnants, 50% had a pituitary deficiency, 26% had visual field defects and 12% had impaired visual acuity. No major changes were observed after 5 years. Twelve of the operated patients had a follow-up at 10 years, in eight the cyst remnants or recurrences increased in size over time (p < .05). CONCLUSIONS: Rathke's cleft cysts with a size less than 10 mm rarely grow and our results indicate that radiological follow-up can be restricted to 5 years. In contrast, progression of postoperative remnants or recurrent cysts is more likely and require long-term follow-up.

PURPOSE: Bilateral adrenalectomy (BA) still plays an important role in the management of Cushing's disease (CD). Nelson's syndrome (NS) is a severe complication of BA, but conflicting data on its prevalence and predicting factors have been reported. The aim of this study was to determine the prevalence of NS, and identify factors associated with its development. DATA SOURCES: Systematic literature search in four databases. STUDY SELECTION: Observational studies reporting the prevalence of NS after BA in adult patients with CD. DATA EXTRACTION: Data extraction and risk of bias assessment were performed by three independent investigators. DATA SYNTHESIS: Thirty-six studies, with a total of 1316 CD patients treated with BA, were included for the primary outcome. Pooled prevalence of NS was 26% (95% CI 22-31%), with moderate to high heterogeneity (I2 67%, P < 0.01). The time from BA to NS varied from 2 months to 39 years. The prevalence of NS in the most recently published studies, where magnet resonance imaging was used, was 38% (95% CI 27-50%). The prevalence of treatment for NS was 21% (95% CI 18-26%). Relative risk for NS was not significantly affected by prior pituitary radiotherapy [0.9 (95% CI 0.5-1.6)] or pituitary surgery [0.6 (95% CI 0.4-1.0)]. CONCLUSIONS: Every fourth patient with CD treated with BA develops NS, and every fifth patient requires pituitary-specific treatment. The risk of NS may persist for up to four decades after BA. Life-long follow-up is essential for early detection and adequate treatment of NS.

To diagnose gestational diabetes mellitus (GDM), plasma glucose measurements during oral glucose tolerance test (OGTT) put high demands on the methods in terms of accuracy. The aim was to evaluate and compare diagnostic performance of a point-of-care test and a glucose hexokinase laboratory method. Using risk-based screening, 175 pregnant women were included. They underwent a 75 g OGTT in their 28th (median) week of gestation. Venous blood was collected in two different tubes. Plasma glucose was measured on Cobas c701 and in duplicates on AccuChek Inform II (both methods from Roche Diagnostics). Accuracy was assessed by participating in external control programs with reference method assigned values. The methods were compared for all samples (n = 512) by regression analysis; slope of 0.90 (95% CI: 0.89-0.92), intercept of 0.12 (95% CI: 0.011-0.22) and rs of 0.968. The average bias between AccuChek Inform II and Cobas c701 was -8%. The proportion of women diagnosed with GDM was 25% based on AccuChek Inform II versus 55% for Cobas c701. Results from the external control program showed a bias of approximately 5% for Cobas c701 and no significant bias for AccuChek Inform II. Cobas c701 showed a large bias both towards Accu-Chek Inform II and the reference method used in the external control program, clearly exceeding the desirable bias of <2.6%. The lack of accuracy has great implications on either over- or under-diagnosis of GDM.

Prolactin is known to have immune modulatory effects acting through the prolactin receptor, which is present on a variety of immune cells. Certain chemokines contribute to form the type of T helper (Th) preponderance in the immune response. The objective of this work was to assess if hyperprolactinemia not related to pregnancy is associated with changes in circulating levels of chemokines and other immunological markers. In this cross sectional study, 35 patients with hyperprolactinemia (5 men), and 102 healthy blood donors (19 men) were included. Serum levels of Th1- Th2- and Th17-associated chemokines, C-reactive protein, immunoglobulins, and the B cell attracting chemokine CXCL13 were assessed. The hyperprolactinemic group had significantly higher levels of Th2 associated CCL22 (p=0.022), Th17 associated CXCL1 (p=0.001), B cell attracting CXCL13 (p=0.003), and C-reactive protein (p<0.001) compared to controls, and these proteins were also positively correlated with prolactin levels. While differences in CCL22, CXCL1, CXCL13, and C-reactive protein were present in patients with low or moderate hyperprolactinemia, no differences were observed at high (>3600 mU/l) prolactin levels. To evaluate a possible dose-associated response to prolactin, an in vitro model was used, showing prolactin-induced increase in T-helper cell activation at moderate levels, while activation decreased at higher levels. Hyperprolactinemia seems to have several immunomodulatory effects and was associated with increased levels of chemokines associated with Th2 and Th17 responses and B cell attraction. However, patients with greatly increased prolactin had normal levels of chemokines, and in vitro, high levels of prolactin decreased T-helper cell activation.

BACKGROUND: Studies on the incidence of Cushing's disease (CD) are few and usually limited by a small number of patients. The aim of this study was to assess the annual incidence in a nationwide cohort of patients with presumed CD in Sweden. METHODS: Patients registered with a diagnostic code for Cushing's syndrome (CS) or CD, between 1987 and 2013 were identified in the Swedish National Patient Registry. The CD diagnosis was validated by reviewing clinical, biochemical, imaging, and histopathological data. RESULTS: Of 1317 patients identified, 534 (41%) had confirmed CD. One-hundred-and-fifty-six (12%) patients had other forms of CS, 41 (3%) had probable but unconfirmed CD, and 334 (25%) had diagnoses unrelated to CS. The mean (95% confidence interval) annual incidence between 1987 and 2013 of confirmed CD was 1.6 (1.4-1.8) cases per million. 1987-1995, 1996-2004, and 2005-2013, the mean annual incidence was 1.5 (1.1-1.8), 1.4 (1.0-1.7) and 2.0 (1.7-2.3) cases per million, respectively. During the last time period the incidence was higher than during the first and second time periods (P < 0.05). CONCLUSION: The incidence of CD in Sweden (1.6 cases per million) is in agreement with most previous reports. A higher incidence between 2005 and 2013 compared to 1987-2004 was noticed. Whether this reflects a truly increased incidence of the disease, or simply an increased awareness, earlier recognition, and earlier diagnosis can, however, not be answered. This study also illustrates the importance of validation of the diagnosis of CD in epidemiological research.

OBJECTIVE: Mortality from primary and secondary adrenal insufficiency (AI; PAI and SAI, respectively) is 2-3-fold higher than in the general population. Mortality relates to cardiovascular disease, acute adrenal crisis (AC), cancer and infections; however, there has been little further characterization of patients who have died. DESIGN/METHODS: We analysed real-world data from 2034 patients (801 PAI, 1233 SAI) in the European Adrenal Insufficiency Registry (EU-AIR; NCT01661387). Baseline clinical and biochemical data of patients who subsequently died were compared with those who remained alive. RESULTS: From August 2012 to June 2017, 26 deaths occurred (8 PAI, 18 SAI) from cardiovascular disease (n = 9), infection (n = 4), suicide (n = 2), drug-induced hepatitis (n = 2), and renal failure, brain tumour, cachexia and AC (each n = 1); cause of death was unclear in 5 patients. Patients who died were significantly older at baseline than alive patients. Causes of AI were representative of patients with SAI; however, 3-quarters of deceased patients with PAI had undergone bilateral adrenalectomy (3 with uncontrolled Cushing's disease, 3 with metastatic renal cell cancer). There were no significant differences in body mass index, blood pressure, low-density lipoprotein cholesterol, total cholesterol or electrolytes between deceased and alive patients. Deceased patients with SAI were more frequently male individuals, were receiving higher daily doses of hydrocortisone (24.0 ± 7.6 vs 19.3 ± 5.7 mg, P = .0016) and experienced more frequent ACs (11.1 vs 2.49/100 patient-years, P = .0389) than alive patients. CONCLUSIONS: This is the first study to provide detailed characteristics of deceased patients with AI. Older, male patients with SAI and frequent AC had a high mortality risk.

Of 1324 women diagnosed with gestational diabetes mellitus (GDM) in Sweden, 25% reported >10 years after the delivery that they had developed diabetes mellitus. We assessed the long-term risk of all glucose metabolic abnormalities in a subgroup of these women. Women (n = 51) previously diagnosed with GDM by capillary blood glucose ≥9.0 mmol/L (≈plasma glucose ≥10.0 mmol/L) after a 2 h 75 g oral glucose tolerance test (OGTT) were included. All underwent a clinical and biochemical evaluation, including a second 2 h 75 g OGTT. Individuals with known type 1 diabetes were excluded. At the follow-up, 12/51 (24%) reported previously diagnosed type 2 diabetes. Another four cases were diagnosed after the second OGTT, increasing the prevalence to 16/51 cases (31%). Impaired fasting plasma glucose (IFG) was diagnosed in 13/51 women and impaired glucose tolerance (IGT) in 10/51 women, leaving only 12 women (24%) with normal glucose tolerance. In addition, 2/51 women had high levels of glutamic acid decarboxylase (GAD) antibodies; of these, one woman classified as type 2 diabetes was reclassified as type 1 diabetes, and the second GAD-positive woman was diagnosed with IGT. Of the women diagnosed with GDM by a 2 h 75 g OGTT, a large proportion had impaired glucose metabolism a decade later, including type 1 and type 2 diabetes.

CONTEXT AND OBJECTIVE: Treatment for adrenal insufficiency (AI) remains suboptimal. Despite glucocorticoid replacement, patients with AI have reduced life expectancy and quality of life. This study aimed to describe the spectrum of management of glucocorticoid replacement in patients with AI enrolled in the European Adrenal Insufficiency Registry (EU-AIR). DESIGN, SETTING AND PATIENTS: EU-AIR is a prospective, multinational, multicentre, observational study initiated in August 2012 to monitor the long-term safety of glucocorticoid replacement in routine clinical practice in Germany, the Netherlands, Sweden and the UK (ClinicalTrials.gov identifier: NCT01661387). This analysis included 1166 patients with primary and secondary AI (mean disease duration 16·1 ± 11·6 years) receiving long-term glucocorticoid replacement therapy. MAIN OUTCOME MEASURE: Glucocorticoid type, dose, frequency and treatment regimen were examined. RESULTS: Most patients (87·4%) were receiving hydrocortisone. The most common dose range, taken by 42·2% of patients, was 20 to <25 mg/day; however, 12·6% were receiving doses of ≥30 mg/day. Hydrocortisone was being taken once daily by 5·5%, twice daily by 48·7%, three times daily by 43·6% and four times daily by 2·1%. Patients with primary AI received higher replacement doses than those with secondary AI (23·4 ± 8·9 and 19·6 ± 5·9 mg/day, respectively). Twenty-five different regimens were being used to deliver a daily hydrocortisone dose of 20 mg. CONCLUSIONS: We have shown significant heterogeneity in the type, dose, frequency and timing of glucocorticoid replacement in real-world clinical practice. This reflects dose individualization based on patient symptoms and lifestyle in the absence of data supporting the optimal regimen.

Turner syndrome (TS) is a genetic disorder of females with a prevalence of 1/2000-3000 live female births. The aim of this study was to compare cephalometric variables from adult women diagnosed with TS to a standardized reference group of 31-year old healthy women, and to evaluate the possible effects of human growth hormone (hGH) therapy in women with TS. Registered TS subjects in the Southeast region of Sweden were invited to take part in the study. Twenty-one women aged 36 ± 13(18-57) years accepted participation. Lateral radiographs of the head were analyzed using standard cephalometric methods (Hasund analysis) and with the commercially available soft-ware program FACAD. Comparisons were made with roentgen-cephalometric standards from a reference group of nineteen 31-year old Swedish women. Analysis of the cephalometric radiographs from the TS subjects showed a more retrognathic maxilla (SNA 80.3 ± 5.4) (p = 0.0460) and mandible (SNB 77.0 ± 5.2) (p = 0.0014), and a correspondingly backward position of the chin (SN/Pg 78.9 ± 5.5) (p = 0.0046) as compared to the reference values of 31-year old women (SNA 83.2 ± 3.0, SN B 81.5 ± 2.3 and SNPg 83.0 ± 2.3, respectively). In addition there was an increased posterior inclination of the maxilla (SN/NL 8.6 ± 4.1), as compared to the reference values (SN/NL 5.3 ± 2.7) (p = 0.0048). There were no significant differences regarding sagittal or vertical jaw relations, mandibular inclination or cranial base angle between the TS-group and the 31-year olds with the reference values. No significant difference was seen in jaw relationship, as measured by the ANB value, however the Wits(index) (3.3 ± 3.5) was higher (p = 0.0001) than the reference values (-0.1 ± 1.8). Subjects with or without previous hGH administration did,not show any significant differences in cephalometric values. In conclusion, women with TS had a significantly more retrognathic maxilla (SNA) and mandible (SNB) and a correspondingly significantly posterior position of the chin (SN/Pg), a significantly increased posterior inclination of the maxilla (SN/NL) and a significantly increased Wits(index) as compared to the reference group of 31-year old women. No craniofacial variables differed significantly between previously hGH-treated and not hGH-treated women with TS.

Free milk-type oligosaccharides are produced during pregnancy and lactation and may have an impact on several cells in the immune system. Our aim was to investigate if patients with isolated hyperprolactinaemia, not related to pregnancy, also have increased synthesis and urinary excretion of milk-type oligosaccharides and to compare the excretion pattern with that found during pregnancy. Urine samples were collected as morning sample from 18 patients with hyperprolactinaemia, 13 healthy controls with normal prolactin levels and four pregnant women. After purification, lactose and free oligosaccharides were analysed and quantified by high-performance anion-exchange chromatography with pulsed amperometric detection. The identity of peaks was confirmed by exoglycosidase treatment and comparison with oligosaccharide standards. Prolactin was measured in serum collected between 09 and 11 a.m. by a standardized immunochemical method. Patients with hyperprolactinaemia had higher urinary excretion of lactose than normoprolactinemic controls and urinary lactose correlated positively to prolactin levels (r = 0.51, p < 0.05). Increased levels of the fucosylated oligosaccharides 2-fucosyl lactose and lacto-di-fucotetraose were found in urine from three and two patients, respectively. The acidic oligosaccharide 3-sialyl lactose was found in high amount in urine from two patients with prolactin of >10,000 mU/l. However, pregnant women in their third trimester had the highest concentration of all these oligosaccharides and excretion increased during pregnancy. This study is first to show that both lactose and certain fucosylated and sialylated milk-type oligosaccharides are increased in some patients with hyperprolactinaemia. It remains to elucidate the functional importance of these findings.

BACKGROUND: Increased morbidity and mortality associated with conventional glucocorticoid replacement therapy for primary adrenal insufficiency (primary AI; estimated prevalence 93-140/million), secondary AI (estimated prevalence, 150-280/million, respectively) or congenital adrenal hyperplasia (estimated prevalence, approximately 65/million) may be due to the inability of typical glucocorticoid treatment regimens to reproduce the normal circadian profile of plasma cortisol. A once-daily modified-release formulation of hydrocortisone has been developed to provide a plasma cortisol profile that better mimics the daytime endogenous profile of cortisol. Here, we describe the protocol for the European Adrenal Insufficiency Registry (EU-AIR), an observational study to assess the long-term safety of modified-release hydrocortisone compared with conventional glucocorticoid replacement therapies in routine clinical practice (ClinicalTrials.gov identifier: NCT01661387). METHODS: Patients enrolled in EU-AIR have primary or secondary AI and are receiving either modified-release or conventional glucocorticoid replacement therapy. The primary endpoints of EU-AIR are the incidence of intercurrent illness, adrenal crisis and serious adverse events (SAEs), as well as the duration of SAEs and dose changes related to SAEs. Data relating to morbidity, mortality, adverse drug reactions, dosing and concomitant therapies will be collected. Patient diaries will record illness-related dose changes between visits. All decisions concerning medical care are made by the registry physician and patient. Enrolment is targeted at achieving 3600 patient-years of treatment (1800 patient-years per group) for the primary analysis, which is focused on determining the non-inferiority of once-daily modified-release replacement therapy compared with conventional glucocorticoid therapy. RESULTS: Recruitment began in August 2012 and, as of March 2014, 801 patients have been enrolled. Fifteen centres are participating in Germany, the UK and Sweden, with recruitment soon to be initiated in the Netherlands. CONCLUSIONS: EU-AIR will provide a unique opportunity not only to collect long-term safety data on a modified-release preparation of glucocorticoid but also to evaluate baseline data on conventional glucocorticoid replacement. Such data should help to improve the treatment of AI.

BACKGROUND: To investigate the erythropoietic activity and safety aspects of testosterone undecanoate (TU) injections in transgender men, assigned female at birth. METHODS: Twenty-three men (13 hypogonadal cisgender men and 10 transgender men) who initiated TU at the study start (naïve) and 15 men (10 hypogonadal cisgender men and 5 transgender men) on steady-state treatment with TU (non-naïve) were included in this prospective 1-year observational study. A control group of 32 eugonadal cisgender men was investigated once at baseline. Complete blood count, testosterone in serum and saliva, and plasma lipids, and liver enzymes were assessed. RESULTS: For naïve transgender men, a significant increase in hemoglobin concentration was noted (mean (SD)), 141 (8)â g/L to 151 (13)â g/L, while no increase was seen in naïve hypogonadal cisgender men. At the end of the study, naïve transgender men exhibited comparable levels of hemoglobin, hematocrit, and testosterone levels in serum and saliva to hypogonadal cisgender men, as well as to the eugonadal cisgender men. During the study, HDL-cholesterol decreased significantly in naïve transgender men, 1.4 (0.4)â mmol/L to 1.2 (0.4)â mmol/L, P = 0.03, whereas no significant change was noted in naïve hypogonadal cisgender men. Liver enzymes remained unchanged in all groups. CONCLUSIONS: After 12 months of treatment with TU in naïve transgender men, hemoglobin and hematocrit increased to levels within the cisgender male reference range. A slight decrease in HDL-cholesterol was seen in naïve transgender men but liver enzymes remained unchanged.

CONTEXT: Turner syndrome (TS) is the most common chromosomal aberration in women; it is the result of structural or numeric abnormalities in the X chromosome. Autoimmune hypothyroidism has been recognized as one of the more prominent disorders associated with TS. OBJECTIVE: This work aimed to study the prevalence of autoimmune diseases in TS. METHODS: A cross-sectional, longitudinal, 25-year follow-up study was conducted of patients from adult Turner centers at the University Hospitals, Sweden. During 1994 to 2020, a total of 503 women aged 16 to 71 years with TS were evaluated consecutively every fifth year according to national guidelines. A random population sample of women, n = 401, aged 25 to 44 years, from the World Health Organization Monitoring of Trends and Determinants for Cardiovascular Disease (MONICA) project served as controls. Serum thyrotropin, free thyroxine, vitamin B12, antithyroid peroxidase (anti-TPO), and antitransglutaminase antibodies were measured. RESULTS: Mean follow-up time (years) was 16 ± 7 for patients and 13 ± 1 for controls. From study start, the prevalence increased in TS for hypothyroidism 40% to 58%, vitamin B12 deficiency 5% to 12%, celiac disease 4% to 7%, positive anti-TPO 26% to 41%, and antitransglutaminase antibodies 6% to 8% (P < .0001 vs controls). Type 1 diabetes and Addison disease were rare. The only interrelationship was between hypothyroidism and vitamin B12 deficiency, both in TS and controls. No association between autoimmune disease and karyotype, antecedent growth hormone treatment, or ongoing estrogen hormone replacement, was seen in TS. CONCLUSION: In women with TS up to older than 80 years, more than half developed hypothyroidism, mainly autoimmune, during follow-up. Awareness of vitamin B12 deficiency and celiac disease throughout life is also recommended in women with TS.

Background: Despite progress in managing cancer in children, adolescents, and young adults (CAYAs), persistent complications may impact their quality of life. This study covers the morbidity and mortality, among CAYAs, with the aim to investigate the influence of socioeconomic factors on outcomes. Methods: This retrospective matched cohort study included the entire Swedish population of individuals under 25 with cancer 1958-2021. The population was identified from the Cancer Register, and controls were paired 1:5 based on age, sex, and residence. Multiple registers provided data on morbidity, mortality, and demographics. Findings: This survey covering 63 years, identified 65,173 CAYAs and matched controls, a total of 378,108 individuals (74% females). CAYAs exhibited a 3.04-times higher risk for subsequent cancer (Odds ratio (OR) 95% confidence interval (CI) 2.92-3.17, p < 0.0001), a 1.23-times higher risk for cardiovascular disease (OR 95% CI 1.20-1.26, p < 0.0001), and a 1.41-times higher risk for external affliction (OR 95% CI 1.34-1.49, p < 0.0001). CAYAs had a higher mortality hazard, and after adjusting for socioeconomic factors, males, individuals born outside Europe, and those with greater sick-leave had a higher association with mortality, while education and marriage showed a beneficial association. Interpretation: The Rebuc study, showed an increased risk for serious complications among young cancer patients in Sweden. Patient-specific variables, demographics, and socioeconomic factors influenced mortality. These results underscore the impact of cancer on the health and lifespan of young individuals and the necessity for further research to address socioeconomic disparities in cancer care.

RESUMO
Increased levels of prolactin often coincide with an increased risk for thromboembolic events, but it is unclear whether a direct causal relation exists. Our aim was to examine the effect of prolactin on platelet function. In addition to using recombinant prolactin for experiments in vitro, we analyzed platelet function by flow cytometry in a group of 13 females with hyperprolactinaemia and 18 healthy female controls. Platelet activation was measured by P-selectin expression and by the amount of platelet-bound fibrinogen after stimulation with adenosine di phosphate (ADP), collagen-related peptide and the protease activated receptor (thrombin receptor) (PAR)-activating peptides PAR4-AP and PAR1-AP. Free oscillation rheometry was used to measure clotting time in whole blood. No significant effect on platelet activation or clotting time could be seen in in vitro experiments by adding recombinant prolactin. However, significantly lower P-selectin expression was found in the hyperprolactinemic group when platelets were activated by ADP (5 and 10 µM) or PAR4-AP. The expression of fibrinogen did not differ between the two groups for any of the activators used. For all samples, inverse significant correlations between P-selectin expression and prolactin concentration were found for both 5 µM ADP (r = - 0.61, p < 0.01), 10 µM ADP (r = - 0.62, p < 0.001) and PAR4-AP (r = - 0.69, p < 0.001). Thrombin cleavage of recombinant prolactin resulting in a 16 kDa C-terminal fragment did not alter the P-selectin expression upon activation. We found an indirect inhibitory effect of prolactin on platelets in hyperprolactinemic patients, suggesting that prolactin might have a protective role in thromboembolic disease.

OBJECTIVE: Data on pre- and postoperative pituitary function in nonfunctioning pituitary adenomas (NFPA) are not consistent. We aimed to investigate pituitary function before and up to 5 years after transsphenoidal surgery with emphasis on the hypothalamic-pituitary-adrenal axis (HPA). DESIGN AND METHODS: Data from the Swedish Pituitary Register was used to analyze anterior pituitary function in 838 patients with NFPA diagnosed between 1991 and 2014. Patients who were reoperated or had received radiotherapy were excluded. RESULTS: Preoperative ACTH, TSH, LH/FSH, and GH deficiencies were reported in 31% (236/755), 39% (300/769), 51% (378/742), and 28% (170/604) of the patients, respectively. Preoperative median tumor volume was 5.0 (2.4-9.0) cm3. Among patients with preoperative, 1 year and 5 years postoperative data on the HPA axis (n = 428), 125 (29%) were ACTH-deficient preoperatively. One year postoperatively, 26% (32/125) of them had recovered ACTH function while 23% (70/303) patients had developed new ACTH deficiency. Thus, 1 year postoperatively, 163 (38%) patients were ACTH-deficient (P < .001 vs. preoperatively). No further increase was seen 5 years postoperatively (36%, P = .096). At 1 year postoperatively, recoveries in the TSH and LH/FSH axes were reported in 14% (33/241) and 15% (46/310), respectively, and new deficiencies in 22% (88/403) and 29% (83/288), respectively. CONCLUSIONS: Adrenocorticotrophic hormone deficiency increased significantly at 1 year postoperatively. Even though not significant, some patients recovered from or developed new deficiency between 1 and 5 years postoperatively. This pattern was seen in all axes. Our study emphasizes that continuous individual evaluations are needed during longer follow-up of patients operated for NFPA.

BACKGROUND: Women with Turner syndrome (TS) have an increased risk of aortic dissection. The current recommended cutoff to prevent aortic dissection in TS is an aortic size index (ASI) of ≥2.5 cm/m2. This study estimated which aortic size had the best predictive value for the risk of aortic dissection, and whether adjusting for body size improved risk prediction. METHODS: A prospective, observational study in Sweden, of women with TS, n = 400, all evaluated with echocardiography of the aorta and data on medical history for up to 25 years. Receiver operating characteristic (ROC) curves, sensitivity and specificity were calculated for the absolute ascending aortic diameter (AAD), ascending ASI and TS specific z-score. RESULTS: There were 12 patients (3%) with aortic dissection. ROC curves demonstrated that absolute AAD and TS specific z-score were superior to ascending ASI in predicting aortic dissection. The best cutoff for absolute AAD was 3.3 cm and 2.12 for the TS specific z-score, respectively, with a sensitivity of 92% for both. The ascending ASI cutoff of 2.5 cm/m2 had a sensitivity of 17% only. Subgroup analyses in women with an aortic diameter ≥ 3.3 cm could not demonstrate any association between karyotype, aortic coarctation, bicuspid aortic valve, BMI, antihypertensive medication, previous growth hormone therapy or ongoing estrogen replacement treatment and aortic dissection. All models failed to predict a dissection in a pregnant woman. CONCLUSIONS: In Turner syndrome, absolute AAD and TS-specific z-score were more reliable predictors for aortic dissection than ASI. Care should be taken before and during pregnancy.

PURPOSE: To describe the clinical presentation and treatment outcomes in a nationwide cohort of patients with giant prolactinomas. METHODS: Register-based study of patients with giant prolactinomas [serum prolactin (PRL) > 1000 µg/L, tumor diameter ≥40 mm] identified in the Swedish Pituitary Register 1991-2018. RESULTS: Eighty-four patients [mean age 47 (SD ±16) years, 89% men] were included in the study. At diagnosis, the median PRL was 6305 µg/L (range 1450-253 000), the median tumor diameter was 47 mm (range 40-85), 84% of the patients had hypogonadotropic hypogonadism, and 71% visual field defects. All patients were treated with a dopamine agonist (DA) at some point. Twenty-three (27%) received 1 or more additional therapies, including surgery (n = 19), radiotherapy (n = 6), other medical treatments (n = 4), and chemotherapy (n = 2). Ki-67 was ≥10% in 4/14 tumors. At the last follow-up [median 9 years (interquartile range (IQR) 4-15)], the median PRL was 12 µg/L (IQR 4-126), and the median tumor diameter was 22 mm (IQR 3-40). Normalized PRL was achieved in 55%, significant tumor reduction in 69%, and combined response (normalized PRL and significant tumor reduction) in 43%. In the primary DA-treated patients (n = 79), the reduction in PRL or tumor size after the first year predicted the combined response at the last follow-up (P < .001 and P = .012, respectively). CONCLUSION: DAs effectively reduced PRL and tumor size, but approximately 1 patient out of 4 needed multimodal treatment. Our results suggest that the response to DA after 1 year is useful for identifying patients who need more careful monitoring and, in some cases, additional treatment.
