RESUMEN

Superselective adrenal artery embolization (SAAE) offers a novel approach for treating primary aldosteronism (PA). In this study, we aimed to assess the efficacy and safety of SAAE for the treatment of PA based on the lateralization results obtained from adrenal vein sampling (AVS).In this prospective study, we enrolled 40 patients with PA who underwent SAAE. The patients were categorized into two groups, unilateral PA and bilateral PA, based on AVS results. Clinical parameters and biochemical markers were assessed at 3 and 12 months postoperatively. The primary outcomes were changes in blood pressure and defined daily dose (DDD) of antihypertensive medications compared to baseline. Thirty-eight patients achieved technical success, with favorable clinical and biochemical efficacy rates. At three months postoperatively, the clinical efficacy rates were 79.2% and 78.6% for the UPA and BPA groups, respectively. At 12 months, the rates were 83.3% and 71.4%, respectively. Both groups exhibited a significant decrease in average blood pressure at 3 and 12 months compared with baseline (P < 0.001), and there was also a notable reduction in DDD (P < 0.05). At three months, the biochemical efficacy rates were 61.9% and 58.3% in the UPA and BPA groups, respectively. Due to loss to follow-up, biochemical indicators were not assessed at 12 months postoperatively. No severe adverse reactions occurred during or after SAAE. Patients with both UPA and BPA can benefit from SAAE. The superiority of bilateral adrenal artery embolization in the treatment of BPA over unilateral adrenal artery embolization requires further investigation.

RESUMEN

Adrenalectomy is the gold standard for canine adrenal tumours, but not always recommended due to patient age, underlying conditions and perioperative mortality. Ethanol ablation is an alternative in human medicine for poor surgical candidates. A 13-year-old neutered female toy-poodle with hypercortisolism presented with severe haematuria. Ultrasonography revealed left adrenal and right kidney tumours. Due to high surgical risk, simultaneous laparotomic right nephroureterectomy and ethanol ablation of the left adrenal tumour were performed. Post-ethanol injection complications included transient hypertension and arrhythmia, which resolved spontaneously. The adrenal tumour size decreased within 2.5 months, and cortisol levels normalised within 8 days, remaining stable for 12 months. No hypercortisolism signs were observed without trilostane until death from renal insufficiency. Autopsy showed that the ablated left adrenal gland was an adrenocortical tumour and had shrunk. Ethanol ablation may be a feasible alternative to adrenalectomy for high-risk canine patients.

RESUMEN

Central adrenal insufficiency (CAI) is a rare endocrine disorder characterized by insufficient secretion of adrenocorticotropic hormone (ACTH) from the pituitary gland, resulting in decreased cortisol production. Here, we present the case of a 19-year-old female with suspected iatrogenic CAI possibly induced by a levonorgestrel-releasing intrauterine system (LNG-IUS). The patient presented with syncopal events, fatigue, and hypotension, prompting admission to the emergency department. Initial investigations revealed low morning cortisol levels and an inadequate cortisol response to ACTH stimulation, supporting the diagnosis of CAI. Treatment with glucocorticoid replacement therapy led to clinical improvement. Removal of the LNG-IUS led to the recovery of the hypothalamic-pituitary axis. Despite the absence of documented cases of LNG-IUS-induced CAI in literature, similarities with other progestin formulations suggest a potential mechanism involving interaction with glucocorticoid receptors. Further research is needed to elucidate the exact pathophysiology and evaluate the safety of LNG-IUS in relation to the hypothalamic-pituitary-adrenal (HPA) axis. This case underscores the importance of considering hormonal contraceptives as potential triggers of CAI in clinical practice.

RESUMEN

Background: Sheehan syndrome is the infarction of a pituitary gland that has been physiologically enlarged as a result of postpartum bleeding. Agalactorrhea and amenorrhea are classic symptoms, but a constellation of manifestations occurs in both the acute and chronic forms. These manifestations can remain largely nonemergent unless Sheehan syndrome is complicated by severe adrenal dysfunction secondary to an inciting event such as dengue. We present a case of Sheehan syndrome that was uncovered in a patient with a dengue infection presenting as adrenal crisis. Case Report: A 45-year-old female presented with symptoms of acute gastroenteritis and severe dehydration. Her medical history was significant for secondary amenorrhea for 14 years after her last delivery followed by symptoms of endocrine dysfunction. At presentation, the patient was in adrenal crisis with hypotension, hypoglycemia, and hyperthermia. Dengue nonstructural protein 1 antigen was positive, along with signs of plasma leakage. Bloodwork showed bicytopenia with abnormal liver enzymes. Ultrasonography and computed tomography of the abdomen were suggestive of serositis with acalculous cholecystitis. Magnetic resonance imaging of the brain revealed an empty sella. Anterior pituitary hormone levels were significantly decreased with low serum cortisol, and the patient's thyroid profile analysis suggested secondary hypothyroidism. The final diagnosis was Sheehan syndrome presenting as adrenal crisis precipitated by severe dengue fever. The patient was managed conservatively and discharged on hormone supplement therapy. Conclusion: Sheehan syndrome is an important cause of panhypopituitarism in the developing world. Knowledge of Sheehan syndrome is important to help prevent its occurrence and reduce its resultant multifactorial effects.

RESUMEN

Aims: To compare nonfunctional adrenal incidentalomas (NFAI) in individuals with and without a history of COVID-19 infection, while also establishing predictive models for distinguishing between benign and malignant adrenal incidentalomas (AI). Methods: A retrospective collection of data from patients with AI who underwent surgery and were verified in our hospital between April 2022 and June 2023 was conducted. A total of 121 patients were included in the study. Demographic information, tumor characteristics, functional indicators, and complications were compared among the patients. Statistical analyses utilized the t-test for continuous variables and Pearson chi-square test or Fisher's exact test for categorical variables. Results: Patients with COVID-19 exhibited a higher prevalence of obesity (84.2% vs. 63.3%, P=0.048) and elevated direct bilirubin (DBIL) levels (44.1% vs. 19.2%, P=0.043) compared to those without COVID-19. Moreover, patients with Malignant AI, in contrast to Benign AI, showed higher normal total protein (TP) levels (28.8% vs. 57.1%, P=0.016) and larger tumor sizes (20 vs. 32.5mm, P=0.009). Univariate analysis identified low TP (OR=0.303, 95% CI=0.111-0.825, P=0.020) and tumor size (OR=1.045, 95% CI=1.011-1.080, P=0.009) as potential risk factors for multivariate analysis. A predictive model comprising clinical risk factors (tumor size and low TP) demonstrated an AUC of 0.754 (95% CI, 0.603-0.904) with a sensitivity of 0.75 and specificity of 0.775. The calibration curve revealed a bias-corrected AUC of 0.77. Conclusion: No discernible differences in the clinical manifestations of adrenal incidentalomas were observed between cases with and without a history of COVID-19 infection. However, AI with larger tumor diameters and lower than normal levels of total protein exhibited a more pronounced malignant potential.

RESUMEN

Apparent bilateral adrenal suppression (ABAS), where aldosterone/cortisol ratios in both adrenal veins are lower than in the inferior vena cava, yields uninterpretable adrenal venous sampling (AVS) results and is poorly understood. A 57-year-old male with hypertension and spontaneous hypokalemia was admitted to our hospital. Confirmatory tests established a diagnosis of primary aldosteronism (PA). Initial AVS indicated ABAS, but unilateral PA remained possible due to elevated aldosterone, low renin, hypokalemia, and a right adrenal nodule (8 × 7 mm) on computed tomography. Subsequently, a second, super-selective AVS identified tributaries from areas of aldosterone hypersecretion, enabling accurate localization of unilateral PA. ABAS may occur due to anatomical factors such as dilution by tributaries from nonaldosterone-producing adenoma (APA) areas with suppressed aldosterone production. Super-selective AVS proves beneficial in diagnosing unilateral PA concealed within ABAS by pinpointing tributaries from APA regions.

RESUMEN

Pheochromocytomas are rare adrenal medulla tumors originating from chromaffin cells, accounting for 10% of primary adrenal neoplasms. Oncocytic variants of pheochromocytomas are rare and have been reported in only 150 cases. This report describes the case of a 60-year-old female who arrived with a non-functional adrenal tumor. This case report emphasizes the importance of a comprehensive histological and immunohistochemical study for diagnosing this rare diagnostic entity and its potential diagnostic pitfalls.

RESUMEN

OBJECTIVES: 1) To examine anthropometric changes of patients with classic 46,XX CAH and matched referents; 2) To investigate the impact of improvements in diagnosis and care on growth patterns in these patients by comparing changes in anthropometric parameters before and after CAH consensus guidelines. METHODS: This was a retrospective cohort study nested within three large integrated health-systems. Seventy-six patients with classic 46XX CAH and 1,102 matched referents <21 years of age were identified. Anthropometric measurements including age-specific percentiles for height, weight, and body mass index were examined and compared between groups using linear mixed-effect models. Anthropometric trajectories were explored using latent class analyses (LCA). RESULTS: CAH patients had lower height percentiles than referents at all time points. Differences ranged from 10.7% to 28.4%. After age 5 differences in height were only significant among study participants born before the publication of CAH consensus guidelines. LCA of height detected a "gradual growth increase" pattern in 28% of CAH cases and only 4% of referents, and a "growth stunting" pattern was observed in 13% of CAH cases and 6% of referents. Height percentile measures did not differ in CAH patients with or without evidence of hormonal interventions (growth hormone and/or puberty blockers) used to increase adult height. CONCLUSIONS: There is substantial heterogeneity in growth trajectories of CAH patients. Although stunting may affect CAH patients, advances in diagnosis and care improved anthropometric outcomes in this population. Understanding the disease- and therapy-related mechanisms that explain the different growth patterns requires additional research.

RESUMEN

BACKGROUND: Mitotane is the cornerstone of adjuvant adrenocortical cancer (ACC) treatment. However, its use is burdened with frequent adverse events. METHODS: A retrospective analysis of adverse events was performed in 26 ACC patients adjuvantly treated with mitotane. RESULTS: Mitotane toxicity was present in all patients (100%). Two (7.7%) patients developed 1-3 adverse events, 15 (57.7%) experienced 4-6 adverse events and 9 (34.6%) patients had more than 6 adverse events. Two (7.7%) patients discontinued mitotane due to adverse events. CONCLUSION: Careful monitoring and timely management are essential for ensuring mitotane treatment adherence and maximizing its benefits.

RESUMEN

Maternal primary adrenal insufficiency (PAI) during pregnancy, due to either Addison disease (AD) or congenital adrenal hyperplasia (CAH), is rare. Only few studies have examined the subsequent important outcomes of maternal glucocorticoid and mineralocorticoid deficiencies during pregnancy upon the fetus and the neonate. Therefore, this systematic review and meta-analysis evaluated the impact of these deficiencies, with data from PubMed/Medline, Cochrane/CENTRAL, and Google Scholar. A total of 31 studies were included for qualitative analysis and 11 for quantitative analysis. Studies examining the prevalence of spontaneous abortion, preterm birth, the occurrence of small for gestational age (SGA) neonates, as well as the neonatal birth weight were included. The systematic review revealed a substantial number of spontaneous abortions, preterm births and SGA neonates in pregnant women with PAI. The meta-analysis showed a mean spontaneous abortion prevalence of 18%, 18% and 17% in women with PAI, AD or CAH, respectively. The mean preterm birth prevalence was 11% when women with AD or CAH were analyzed together, and 13% and 9% in women with AD or CAH, respectively, when these women were analyzed separately. The mean prevalence of SGA neonates was 8% when women with AD or CAH were analyzed together, and 5% and 10% in women with AD or CAH, respectively, when these women were analyzed separately. The mean fetal birth weight was within normalcy in all women with PAI, as well as in women with AD or CAH. In conclusion the executed systematic review of 31 studies followed by a meta-analysis of 11 studies in pregnant women with PAI has shown a greater prevalence of pregnancies with negative outcome (spontaneous abortion, preterm birth) and of negative fetal outcome (SGA) in women with either AD or CAH, as compared to control pregnant women.

RESUMEN

Depression, which affects millions of individuals worldwide, is associated with glucocorticoid (GC) impairment, with the FKBP51 protein playing a pivotal role. Ginsenosides, extracted from the root of Panax ginseng C.A. Mey, have demonstrated the potential to mitigate depression associated with GC dysregulation. This study evaluated the therapeutic efficacy of ethanol extract of P. ginseng (PG) in treating depression and its underlying FKBP51-linked mechanism. Using chronic unpredictable stress, a depression model was developed in Kunming mice to test the efficacy of PG by observing changes in behaviors and protein expression in depressed mice. The mechanism of action was investigated through transfection with HEK293T cells. Depressed mice treated with PG demonstrated notable improvements: the rate of weight loss was reduced, sucrose preference and open-field activity were enhanced, and the rate of apoptosis in hippocampal cells was decreased. Additionally, the HPA axis function appeared to be restored. These physiological adjustments coincided with an increase in GR levels and a decrease in FKBP51 levels. Altogether, these results suggested that PG treatment effectively alleviates depressive symptoms in mice. PG also moderated FKBP51-GR interaction, lessening FKBP51's restraint on GR nuclear entry. This modulation may enhance the sensitivity of the GR response, reinforcing the negative feedback regulation of the HPA axis and thereby reducing depressive symptoms in mice. These findings highlight the potential of PG as a promising curative treatment for depression, providing a basis for the development of innovative treatments targeting the FKBP51-GR pathway.

RESUMEN

At the end of 2023, the European Journal of Endocrinology published the latest guidelines of the European Society of Endocrinology (ESE) on the management of accidentally detected adrenal tumours (incidentalomas) in adults. Comparing them with the previous version of the ESE recommendations from 2016, a tendency towards far-reaching individualisation of the therapeutic and diagnostic approach in patients with adrenal incidentaloma can be seen - it is reflected by changes in the initial assessment of the malignancy of the lesion, in the scope of the proposed hormonal assessment, and qualification for surgery. The latest version of the guidelines includes 9 completely new recommendations, and 5 more recommendations have been significantly changed. Among the most important changes, the introduction of the term "mild autonomous cortisol secretion" (MACS) instead of the previously used term "autonomous cortisol secretion (ACS)" along with more precise recommendations regarding its management should be emphasised. An important novelty is also the modification of the criteria for benign adrenal adenoma, which does not require further imaging observation - due to the results of recent clinical studies, the authors have removed the criteria of size below 4 cm from the definition. Among others, the guidelines also encourage more proactive surgical treatment of indeterminate adrenal incidentaloma in people < 40 years of age and pregnant women. The authors of the recommendations repeatedly accentuate the importance of a multidisciplinary approach in making decisions regarding further management of patients with an unspecified adrenal tumour. Despite a few significant differences compared to the previous version of guidelines, the authors emphasise the presence of gaps in the current scientific evidence, which would not allow for the formulation of more unambiguous recommendations. The need to optimise ordered diagnostic tests, which generate additional socio-economic burdens without negative impact on patients' health, is also an important aspect of the latest guidelines.

RESUMEN

Oncocytoma is a tumour that predominantly occurs in the kidneys and salivary glands. Only approximately 200 cases have been reported to be of adrenal origin to date, and only a few reports about its radiological findings have been published so far. Herein, we present the CT and MRI findings of an adrenal oncocytoma observed in a patient suspected of having mitochondrial abnormalities, along with the pathological findings. The tumour was roughly classified into three areas: a hypercellular region, a region containing fibrous tissue, and an oedematous region. These corresponded to the restricted diffusion area on the apparent diffusion coefficient map, the gradually enhanced area at the secretory phase on contrast-enhanced CT scan, and the obvious hyperintensity on the T2-weighted image, respectively. We also discuss these findings in the context of previously reported radiological findings in the literature. Diagnosing adrenal oncocytoma through imaging is challenging, and it is crucial to consider the possibility of malignancy while making the differential diagnosis. Small-sized homogenous tumours may be hard to differentiate from lipid-poor adenomas, while larger inhomogeneous ones are hard to distinguish from adrenal cancer.

RESUMEN

Ganglioneuroma is a well-differentiated tumor originating from neural crest cells of the sympathetic nervous system. Although benign, a few cases have been reported that ganglioneuroma can metastasize to other sites. We report a case of adrenal ganglioneuroma with para-aortic nodal metastases with low FDG and MIBG uptake. In order to avoid unnecessary wide excision or aggressive medication, it is important to consider the possibility of ganglioneuroma preoperatively even if with metastases.

RESUMEN

INTRODUCTION: Adrenoleukodystrophy (ALD) patients exhibit three primary clinical phenotypes: primary adrenal insufficiency, adrenomyeloneuropathy, and cerebral demyelination due to the accumulation of saturated very long-chain fatty acids in the adrenal cortex and central nervous system white matter and axons. We investigated the diagnosis of adrenal insufficiency (AI) and the use of mineralocorticoid treatment in male ALD patients. METHODS: A retrospective chart review of electronic medical records was conducted for all ALD patients at a single institution between January 1, 2011, and December 6, 2021. RESULTS: Among the 437 ALD patients, 82% were male and 18% were female. Of the male ALD patients, 60% (213 out of 358) had a diagnosis of AI, and 39% (84 out of 213) of those with AI were prescribed mineralocorticoid replacement therapy. CONCLUSION: AI is highly prevalent among ALD patients, with approximately 40% of those with a diagnosis of AI undergoing mineralocorticoid replacement therapy. Further research is warranted to delineate the characteristics of patients predisposed to developing mineralocorticoid deficiency within the context of ALD and AI.

RESUMEN

Glucocorticoid (GC) levels have significant impacts on the health and behaviour of wildlife populations and are involved in many essential body functions including circadian rhythm, stress physiology and metabolism. However, studies of GCs in wildlife often focus on estimating mean hormone levels in populations, or a subset of a population, rather than on assessing the entire distribution of hormone levels within populations. Additionally, explorations of population GC data are limited due to the tradeoff between the number of individuals included in studies and the amount of data per individual that can be collected. In this study, we explore patterns of GC level distributions in three white-tailed deer (Odocoileus virginianus) populations using a non-invasive, opportunistic sampling approach. GC levels were assessed by measuring faecal corticosterone metabolite levels ('fCMs') from deer faecal samples throughout the year. We found both population and seasonal differences in fCMs but observed similarly shaped fCM distributions in all populations. Specifically, all population fCM cumulative distributions were found to be very heavy-tailed. We developed two toy models of acute corticosterone elevation in an effort to recreate the observed heavy-tailed distributions. We found that, in all three populations, cumulative fCM distributions were better described by an assumption of large, periodic spikes in corticosterone levels every few days, as opposed to an assumption of random spikes in corticosterone levels. The analyses presented in this study demonstrate the potential for exploring population-level patterns of GC levels from random, opportunistically sampled data. When taken together with individual-focused studies of GC levels, such analyses can improve our understanding of how individual hormone production scales up to population-level patterns.

RESUMEN

Background: Mood disorders (MD) are multifactorial disorders. Identifying new biomarkers for the early diagnosis of MD and predicting response to treatment is currently a significant research topic. Both eosinopenia and MD are associated with increased activity of the hypothalamic-pituitary-adrenal axis. The present study, therefore, used a clear definition of chronic idiopathic eosinopenia (CIE) to determine the rate of MD in a large cohort of individuals with CIE. Methods: This retrospective population-based, case-control study uses data of seven consecutive years from the database of Leumit Health Services (LHS) - a nationwide health maintenance organization in Israel. Results: Participants were 13928 LHS members with CIE and 27858 negative controls. The CIE group exhibited significantly higher rates of MD than the control group throughout the whole study period, except for atypical depressive disorder at baseline. Conclusions: CIE might be associated with a higher prevalence of MD. Further basic research should elucidate the pathophysiologic mechanisms linking CIE and MD.
