RESUMEN

CONTEXT: There is a considerable diagnostic delay in acromegaly contributing to increased morbidity. Voice changes due to orofacial and laryngeal changes are common in acromegaly. OBJECTIVE: Our aim was to explore the use of digital voice analysis as a biomarker for acromegaly using broad acoustic analysis and machine learning. METHODS: Voice recordings from patients with acromegaly and matched controls were collected using a mobile phone at Swedish university hospitals. Anthropometric and clinical data and the Voice Handicap Index (VHI) were assessed. Digital voice analysis of a sustained and stable vowel [a] resulted in 3274 parameters, which were used for training of machine learning models classifying the speaker as "acromegaly" or "control". The machine learning model was trained with 76% of the data and the remaining 24% was used to assess its performance. For comparison, voice recordings of 50 pairs of participants were assessed by 12 experienced endocrinologists. RESULTS: We included 151 Swedish patients with acromegaly (13% biochemically active and 10% newly diagnosed) and 139 matched controls. The machine learning model identified patients with acromegaly more accurately [area under the receiver operating curve (ROC AUC) 0.84] than experienced endocrinologists (ROC AUC 0.69). Self-reported voice problems were more pronounced in patients with acromegaly than matched controls (median VHI 6 vs 2, P < .01) with higher prevalence of clinically significant voice handicap (VHI ≥20: 22.5% vs 3.6%). CONCLUSION: Digital voice analysis can identify patients with acromegaly from short voice recordings with high accuracy. Patients with acromegaly experience more voice disorders than matched controls.

RESUMEN

Various factors may affect cognition in patients with pituitary adenoma, including size and extension of the tumor, degree of pituitary hormone deficiencies, and treatment of the tumor, most often being transsphenoidal surgery (TSS). The aim of this cross-sectional study was to evaluate cognitive function in patients with clinically significant pituitary adenoma and to identify factors influencing cognition. Sixty-eight patients with pituitary adenoma were included. Of these, 31 patients were evaluated before TSS and 37 patients 12 months following TSS. Cognitive function was evaluated by using the Repeatable Battery for the Assessment of Neuropsychological Status. Patients had lower mean scores on cognitive assessment compared to age-adjusted normative data. Variability in cognition, analyzed by linear regression analysis, was explained by sex, educational level, and self-perceived fatigue, but not by pituitary hormone deficiencies, diabetes insipidus, or surgical treatment. Our results are in line with previous findings, namely that pituitary adenoma affects cognition. To better evaluate the factors affecting cognition, longitudinal studies are recommended. Such studies would allow for within-individual comparisons, effectively controlling for the considerable influence of sex and education on test results.

RESUMEN

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.

RESUMEN

Acromegaly is a rare endocrine disease caused by hypersecretion of growth hormone, most commonly arising due to a pituitary adenoma. Diabetes mellitus is a common complication of acromegaly, occurring in approximately one-third of patients. The risk of diabetes mellitus in acromegaly is driven by increased exposure to growth hormone, which directly attenuates insulin signalling and stimulates lipolysis, leading to decreased glucose uptake in peripheral tissues. Acromegaly is a unique human model, where insulin resistance occurs independently of obesity and is paradoxically associated with a lean phenotype and reduced body adipose tissue mass. Diabetes mellitus in patients with acromegaly is associated with an increased risk of cardiovascular morbidity and mortality. Therefore, preventive measures and optimized treatment of diabetes mellitus are essential in these patients. However, specific recommendations for the management of diabetes mellitus secondary to acromegaly are lacking due to limited research on this subject. This Review explores the underlying mechanisms for diabetes mellitus in acromegaly and its effect on morbidity and mortality. We also discuss treatment modalities for diabetes mellitus that are suited for patients with acromegaly. Improved understanding of these issues will lead to better management of acromegaly and its associated metabolic complications.

RESUMEN

In this large population-based matched cohort study, patients with primary aldosteronism were at increased risk of hip fracture, particularly subgroups traditionally considered at higher risk of osteoporosis such as women, patients older than 56 years at diagnosis, patients with established cardiovascular disease at diagnosis, and patients treated with MRA. PURPOSE: Previous studies suggest that primary aldosteronism (PA) is associated with dysregulated bone homeostasis. The aim of this study was to evaluate the incidence of hip fractures in patients with PA. METHODS: We studied a nationwide cohort of 2419 patients with PA (1997-2019) and 24 187 age and sex matched controls from the general population. Hip fractures were identified by ICD codes in the Swedish National Patient Register. We estimated hazard ratios (HRs) for incident hip fractures, adjusted for prior fractures, socioeconomic factors, diabetes, osteoporosis, hyperparathyroidism, and cardiovascular disease (CVD). Pairwise subgroup comparisons were performed by age (18-56 and > 56 years), sex, CVD at baseline, and treatment for PA. RESULTS: During a mean follow up of 8 ± 5 years, 64 (2.6%) patients had a hip fracture after being diagnosed with PA, compared to 401 (1.7%) controls. After adjustments, PA was associated with a 55% increased risk of hip fracture compared to controls (HR 1.55 [1.18-2.03]). HRs were increased in women (HR 1.76 [95% CI 1.24-2.52]), patients aged > 56 years (HR 1.62 [95% CI 1.21-2.17]), and patients with CVD at diagnosis (HR 2.15 [95% CI 1.37-3.37]). PA patients treated with adrenalectomy did not have higher risk than controls (HR 0.84 [95% CI 0.35-2.0]), while patients treated with mineralocorticoid receptor antagonists (MRA) retained a greater risk (HR 1.84 [95% CI 1.20-2.83]). CONCLUSION: PA is associated with increased hip fracture risk, especially in women, patients diagnosed after the age of 56 years and patients with established CVD at diagnosis. Also, patients treated with MRA seem to have an increased risk of hip fractures, while adrenalectomy may be protective.

RESUMEN

PURPOSE: To study the long-term effect of transsphenoidal surgery (TSS) on headache in patients with non-functioning pituitary adenoma (NFPA) and identify factors predicting headache relief following TSS. METHODS: We evaluated headache in 101 consecutive patients with NFPA who underwent TSS from September 2015 to December 2021, preoperatively and 12-months post-surgery, by using the Migraine Disability Assessment (MIDAS) questionnaire. Health-related quality of life (QoL) was assessed using the EQ-5D visual analogue scale (EQ-VAS). RESULTS: Of 101 patients, 27 (27%) experienced disabling preoperative headache. Among these, the median total MIDAS score improved from 60 (interquartile range (IQR): 19-140) to 10 (IQR: 0-49) (P = 0.004). Additionally, headache frequency over a 90-day period decreased from 45 (IQR: 25-83) to 6 (IQR: 3-36) days (P = 0.002), and headache intensity decreased from 5 (IQR: 4-7) to 4 (IQR: 2-7) (P = 0.016) at 12-months post-surgery. At 12 months post-surgery, 18 (67%) of 27 patients with preoperatively disabling headache showed clinically relevant improvement of their headache, 4 (15%) showed deterioration, and 5 (19%) remained unchanged. In patients with clinically relevant improvement of their headache, the EQ-VAS score improved from 50 (IQR: 30 - 7) to 80 (IQR: 65-86) (P < 0.001). Of the 74 patients with no preoperative headache, 11 (15%) developed postoperative headache. We identified no clinical factors predicting postoperative headache relief. CONCLUSION: The study supports that clinically significant and long-lasting improvements of disabling headache and QoL can be achieved with TSS in a substantial number of patients with NFPA.

RESUMEN

BACKGROUND: Clinical practice guidelines recommend the Lateralization Index (LI) as the standard for determining surgical eligibility in primary aldosteronism (PA). Our goal was to identify the optimal LI cut-offs in adrenal venous sampling (AVS) for diagnosing PA that is amenable to surgical cure. METHODS: We conducted a retrospective international cohort study across 16 institutions in 11 countries, including 1,550 patients with PA who underwent AVS, with and/or without ACTH stimulation. The establishment of optimal cut-offs was informed by a survey of 82 PA patients in Japan, aimed at determining the LI cut-off aligned with patient expectations for a surgical cure rate. RESULTS: The survey revealed that a median cure rate expectation of 80% would motivate PA patients towards undergoing adrenalectomy. The optimal LI cut-offs achieving an adjusted positive predictive value (PPV) of 80% were identified as 3.8 for unstimulated AVS and 3.4 for ACTH-stimulated AVS. Furthermore, a contralateral ratio of less than 0.4 and the detection of an adrenal nodule on CT imaging were identified as independent predictors of surgically curable PA. Incorporating these factors with the optimal LI cut-offs, the adjusted PPV increased to 96.6% for unstimulated AVS and 89.6% for ACTH-stimulated AVS. No clear differences in predictive ability between unstimulated and ACTH-stimulated LI were found. CONCLUSIONS AND RELEVANCE: The present study clarified the optimal LI cut-offs for without and with ACTH stimulation. The presence of contralateral suppression and adrenal nodule on CT imaging seems to provide additional available information besides LI for surgical indication.

RESUMEN

Renin-secreting tumours are rare causes of secondary hypertension and hypokalaemia. They are usually surgically curable, hence proper diagnostic work-up and tumour localisation is essential. In this paper, we present three Swedish patients recently diagnosed with renin secreting tumours, two with reninomas and one with an extrarenal renin-producing tumour, to illustrate diagnostic challenges. We also discuss the biochemical work-up, the pros and cons of different imaging techniques (computer tomography [CT], magnetic resonance imaging and [18F]fluorodeoxyglucose-positron emission tomography-CT), as well as how renal vein sampling (RVC) may contribute to localisation of the tumour.

RESUMEN

Plasma copeptin is a biomarker that reflects arginine vasopressin (AVP) secretion. In this study we measured copeptin during insulin tolerance test (ITT) in 65 patients referred to our department for evaluation of anterior pituitary function. Plasma for measurements of copeptin were collected at the start of the test and regurarly up to 120 minutes thereafter. Of 60 patients who developed significant hypoglycemia and were included in the analyses, 13 (22%) had corticotropic deficiency, 11 (18%) had thyreotropic deficiency, 33 (55%) had growth hormone deficiency and 4 (6%) had AVP deficieny (AVPD). Thirty-seven (62%) patients had at least one anterior pituitary deficiency. In patients without AVPD, median (range) copeptin increased from 4.5 pmol/L (1.3-33.0) to a maximum of 6.2 pmol/L (2.0-34.4; p<0.001). Baseline copeptin was similar in men and women, but maximal copeptin during ITT was higher in men. Copeptin concentrations were not affected by age, BMI, somatotropic, or corticotropic function. Copeptin concentrations were lower in patients with AVPD than patiets without AVPD, and in patients with thyrotropic deficiency, compared to patients with intact thyrotropic function, both at baseline and during ITT. In conclusion, copeptin increases significantly during insulin induced hypoglycemia but is of limited value in predicting anterior pituitary hormonal function.

RESUMEN

Objective: It is unknown whether glucocorticoid (GC)-induced adrenal insufficiency may cause premature mortality in GC users. We conducted a retrospective cohort study to investigate if undiagnosed and undertreated GC-induced adrenal insufficiency is a contributor to premature death in GC users. Methods: Information on dispensed prescriptions in West Sweden from 2007 to 2014 was obtained from the Swedish Prescribed Drug Register. Cause of death was collected from the Swedish Cause of Death Register. Of 223,211 patients who received oral GC prescriptions, 665 died from sepsis within 6 months of their last prescription. Three hundred of these patients who had died in hospital were randomly selected for further investigation. Medical records were initially reviewed by one investigator. Furthermore, two additional investigators reviewed the medical records of patients whose deaths were suspected to be caused by GC-induced adrenal insufficiency. Results: Of 300 patients (121 females, 40%), 212 (75%) were prescribed GC treatment at admission. The mean age was 76 ± 11 years (range 30-99). Undiagnosed or undertreated GC-induced adrenal insufficiency was considered a probable contributor to death by at least two investigators in 11 (3.7%) patients. In five of these 11 cases, long-term GC therapy was abruptly discontinued during hospitalization. Undiagnosed or undertreated GC-induced adrenal insufficiency was considered a possible contributing factor to death in a further 36 (12%) patients. Conclusion: GC-induced adrenal insufficiency is an important contributor to premature death in GC users. Awareness of the disorder during intercurrent illness and following cessation of GC treatment is essential.

RESUMEN

OBJECTIVES: While glucocorticoid (GC) treatment initiated for COVID-19 reduces mortality, it is unclear whether GC treatment prior to COVID-19 affects mortality. Long-term GC use raises infection and thromboembolic risks. We investigated if patients with oral GC use prior to COVID-19 had increased mortality overall and by selected causes. DESIGN: Population-based observational cohort study. SETTINGS: Population-based register data in Sweden. PARTICIPANTS: All patients infected with COVID-19 in Sweden from January 2020 to November 2021 (n=1 200 153). OUTCOME MEASURES: Any prior oral GC use was defined as ≥1 GC prescription during 12 months before index. High exposure was defined as ≥2 GC prescriptions with a cumulative prednisolone dose ≥750 mg or equivalent during 6 months before index. GC users were compared with COVID-19 patients who had not received GCs within 12 months before index. We used Cox proportional hazard models and 1:2 propensity score matching to estimate HRs and 95% CIs, controlling for the same confounders in all analyses. RESULTS: 3378 deaths occurred in subjects with any prior GC exposure (n=48 806; 6.9%) and 14 850 among non-exposed (n=1 151 347; 1.3%). Both high (HR 1.98, 95% CI 1.87 to 2.09) and any exposure (1.58, 1.52 to 1.65) to GCs were associated with overall death. Deaths from pulmonary embolism, sepsis and COVID-19 were associated with high GC exposure and, similarly but weaker, with any exposure. High exposure to GCs was associated with increased deaths caused by stroke and myocardial infarction. CONCLUSION: Patients on oral GC treatment prior to COVID-19 have increased mortality, particularly from pulmonary embolism, sepsis and COVID-19.

RESUMEN

PURPOSE: Data guiding management of pheochromocytoma and paraganglioma (PPGL) in pregnant women is limited, and long-term effects on the child are unknown. The aim of this retrospective registry-based case-cohort study was to assess how maternal PPGL and treatment impacts maternal and fetal outcome, including long-term outcome for the child. The main outcomes were maternal and fetal mortality and morbidity at delivery and relative healthcare consumption in children born by mothers with PPGL during pregnancy. METHODS: The National Birth Register identified 4,390,869 pregnancies between 1973-2015. Data was crosslinked with three Swedish national registers to identify women diagnosed with pheochromocytoma or paraganglioma within one year before or after childbirth. Hospital records were reviewed and register data was collected for five age-matched controls for each child until age 18. RESULTS: 21 women and 23 children were identified (incidence 4.8/1.000.000 births/year), all women with adrenal pheochromocytomas (Pc). The majority (71%) were diagnosed post-partum. Nine women (43%) were hypertensive during pregnancy. Preterm delivery was more common in Pc patients compared to controls (30% vs 6%, p < 0.001). There was no maternal or fetal mortality. Timing of tumor removal did not affect gestational weight or APGAR scores. There was no observed difference in hospital admissions between children affected by maternal Pc and controls. CONCLUSION: Pc was commonly diagnosed after delivery and raised the risk of pre-term delivery, suggesting a need for an increased awareness of this diagnosis. However, reassuringly, there was no fetal or maternal mortality or any observed long-term impact on the children.

RESUMEN

Women with hypopituitarism have various degrees of androgen deficiency, which is marked among those with combined hypogonadotrophic hypogonadism and secondary adrenal insufficiency. The consequences of androgen deficiency and the effects of androgen replacement therapy have not been fully elucidated. While an impact of androgen deficiency on outcomes such as bone mineral density, quality of life, and sexual function is plausible, the available evidence is limited. There is currently no consensus on the definition of androgen deficiency in women and it is still controversial whether androgen substitution should be used in women with hypopituitarism and coexisting androgen deficiency. Some studies suggest beneficial clinical effects of androgen replacement but data on long-term benefits and risk are not available. Transdermal testosterone replacement therapy in hypopituitary women has shown some positive effects on bone metabolism and body composition. Studies of treatment with oral dehydroepiandrosterone have yielded mixed results, with some studies suggesting improvements in quality of life and sexual function. Further research is required to elucidate the impact of androgen deficiency and its replacement treatment on long-term outcomes in women with hypopituitarism. The lack of transdermal androgens for replacement in this patient population and limited outcome data limit its use. A cautious and personalized treatment approach in the clinical management of androgen deficiency in women with hypopituitarism is recommended while awaiting more efficacy and safety data.

RESUMEN

OBJECTIVE: Plasma copeptin is a relatively new biomarker for evaluation of arginine vasopressin (AVP) secretion. The aim of this study was to test the diagnostic performance of copeptin in patients with polyuria-polydipsia syndrome. DESIGN, PATIENTS AND MEASUREMENTS: This was a prospective study where 88 patients with polyuria-polydipsia syndrome were evaluated with a water deprivation test (WDT). Weight, urine osmolality, urine specific gravity, and plasma copeptin were collected at baseline, after 8 h, and at termination of the WDT when one of the following had been reached: (i) >3% weight reduction, (ii) urine specific gravity >1.017 or urine osmolality >600 mOsm/kg, or (iii) intolerable adverse symptoms. RESULTS: Of 88 patients (57 women), 21 (24%) were diagnosed with central diabetes insipidus (cDI), 5 (6%) with nephrogenic DI (nDI), and 62 (71%) with primary polydipsia (PP). Median (interquartile range) copeptin at baseline was 1.7 (1.4-2.5) pmol/L in cDI, 22 (18-65) pmol/L in nDI, and 2.7 (2-4) pmol/L in PP. After 8 h of WDT, the highest copeptin in patients with cDI was 4.0 pmol/L. In patients with PP: (i) 41 had urine osmolality <600 mOsm/kg, 7 (17%) of these had copeptin >4.0 pmol/L, (ii) 21 had urine osmolality ≥600 mOsm/kg, 14 (67%) of these had copeptin >4.0 pmol/L. CONCLUSIONS: Copeptin >4.0 pmol/L after an overnight WDT can be used to rule out cDI and copeptin ≥21 pmol/L at baseline to diagnose nDI. The diagnostic performance of copeptin in the context of the WDT is otherwise limited in the diagnostic work-up of patients with polyuria-polydipsia syndrome.

RESUMEN

We present a patient with Cushing syndrome secondary to accidental intake of corticosteroid tablets-a 66-year-old woman with a history of well-controlled hypertension, who over the course of a few weeks developed full-blown Cushing syndrome with uncontrolled blood pressure, typical central fat accumulation, and easy bruising. The clinical features further worsened upon increase of the dosage of her antihypertensive medication because of rising blood pressure. Biochemical analyses showed low cortisol and ACTH concentrations. Inspection of the patient's medications revealed that she had accidentally been taking corticosteroids tablets, prescribed for her husband, instead of antihypertensives, ie, dexamethasone 4 mg and then 8 mg, instead of candesartan at the same dose. This case highlights the necessity of a thorough review of the medications taken by patients suspected to have exogenous Cushing syndrome, including inspection of the original packaging, and not just relying on information from the patient and electronic health records. This case also highlights the need of special labeling on the packaging for the easy identification of corticosteroid-containing medications given their widespread availability.

RESUMEN

BACKGROUND: Patients with adrenal insufficiency (AI) have excess morbidity and mortality related to infectious disorders. Whether patients with AI have increased morbidity and mortality from COVID-19 is unknown. METHODS: In this linked Swedish national register-based cohort study, patients with primary and secondary AI diagnosis were identified and followed from 1 January 2020 to 28 February 2021. They were compared with a control cohort from the general population matched 10:1 for age and sex. The following COVID-19 outcomes were studied: incidence of COVID-19 infection, rates of hospitalization, intensive care admission and death. Hazard ratios (HR) with 95% confidence intervals (95% CI) adjusted for socioeconomic factors and comorbidities were estimated using Cox regression analysis. RESULTS: We identified 5430 patients with AI and 54,300 matched controls: There were 47.6% women, mean age was 57.1 (standard deviation 18.1) years, and the frequency of COVID-19 infection was similar, but the frequency of hospitalization (2.1% vs. 0.8%), intensive care (0.3% vs. 0.1%) and death (0.8% vs. 0.2%) for COVID-19 was higher in AI patients than matched controls. After adjustment for socioeconomic factors and comorbidities, the HR (95% CI) was increased for hospitalization (1.96, 1.59-2.43), intensive care admission (2.76, 1.49-5.09) and death (2.29, 1.60-3.28). CONCLUSION: Patients with AI have a similar incidence of COVID-19 infection to a matched control population, but a more than twofold increased risk of developing a severe infection or a fatal outcome. They should therefore be prioritized for vaccination, antiviral therapy and other appropriate treatment to mitigate hospitalization and death.

RESUMEN

Cushing's syndrome (CS) refers to the clinical features of prolonged pathological glucocorticoid excess. About 10-20% of individuals with CS have ectopic CS (ECS), that is, an adrenocorticotropin (ACTH)-producing tumour outside the pituitary gland. ACTH-secreting neuroendocrine neoplasia (NENs) can arise from many organs, although bronchial NEN, small cell lung cancer (SCLC), pancreatic NEN, thymic NEN, medullary thyroid cancer (MTC), and pheochromocytoma are the most common. Patients with ECS frequently present with severe hypercortisolism. The risk of life-threatening complications is high in severe cases, unless the hypercortisolism is effectively treated. A good outcome in ECS requires a methodical approach, incorporating prompt diagnosis, tumour localization, control of cortisol excess, and resection of the primary tumour when possible.

RESUMEN

BACKGROUND: Primary aldosteronism (PA) is associated with increased mortality. The extent to which this phenomenon is affected by sex, age, comorbidities at diagnosis, and different treatment modalities is largely unknown. The objective was to determine all-cause and cause-specific mortality in a population-based cohort of patients with PA and the impact of age at diagnosis, sex, comorbidities, and treatment modalities. METHODS: We used national registers to identify patients diagnosed with PA between 1997 and 2019 (n=2419) and controls (n=24 187) from the general population, matched for sex, age, and county of residence. We obtained mortality data from the Cause-of-Death Register. We used Cox regression models, adjusted for socioeconomic factors and diabetes, to estimate adjusted hazard ratios (HRs [95% CI]). RESULTS: Overall, 346 (14.3%) patients with PA and 2736 (11.3%) controls died during a median follow-up time of 8.1 years. PA was associated with increased risk from all-cause mortality (HR, 1.23 [95% CI, 1.10-1.38]), death from cardiovascular disease (HR, 1.57 [95% CI, 1.30-1.89]), and stroke (HR, 1.85 [95% CI, 1.16-2.93]). Patients with cardiovascular disease at diagnosis (HR, 1.53 [1.26-1.85]), age >56 years (HR, 1.28 [95% CI, 1.13-1.45]), patients treated with a low dose of a mineralocorticoid receptor antagonist (HR, 1.30 [95% CI, 1.02-1.66]), and untreated patients (HR, 2.51 [95% CI, 1.72-3.67]) had excess mortality. CONCLUSIONS: Mortality, mainly due to cardiovascular disease, is increased in patients with PA compared with controls from the general population, particularly in patients aged >56 years, patients with preexisting cardiovascular comorbidities, and patients receiving low dose of a mineralocorticoid receptor antagonist.
