Adrenal Vein Sampling in the Young - Necessary or Not?
- 2023

In: Experimental and Clinical Endocrinology & Diabetes. - 0947-7349. ; 131:07/08, s. 435-437

Research review (peer-reviewed)abstract
- Current clinical guidelines from the US Endocrine Society state that adrenal venous sampling (AVS) may not be necessary in patients younger than 35 years with marked aldosteronism and a solitary adrenal adenoma on imaging. At the time when the guidelines were published, only one study supported the statement, a study that included 6 patients younger than 35 years, all of whom had unilateral adenoma on imaging and unilateral primary aldosteronism (PA), according to AVS. Since then, to our knowledge, four additional studies have been published that provide data on concordance between conventional imaging and AVS among patients younger than 35 years. In these studies, 7 of 66 patients with unilateral disease on imaging had bilateral disease, according to AVS. We find it, therefore, reasonable to conclude that imaging studies alone inaccurately predict laterality in a significant number of young patients with PA and that available data challenge the current clinical guidelines.

Journal article (peer-reviewed)abstract
- Current clinical guidelines suggest that adrenal venous sampling (AVS) may not be mandatory in young patients with primary aldosteronism (PA) and a solitary adrenal adenoma on imaging.The aim of this study was to further elucidate whether conventional imaging alone is sufficient to distinguish unilateral from bilateral PA among patients aged 40 years or younger.This was a retrospective study where data from 45 patients with PA, aged between 26 and 40 years, who underwent successful AVS between 2005 and 2019, were analyzed. Results concerning laterality on imaging studies and AVS were recorded. Outcome in surgically treated patients was assessed according to the Primary Aldosteronism Surgical Outcomes (PASO) criteria.In four of 25 patients with unilateral aldosterone production according to AVS, CT inaccurately suggested bilateral disease. Following unilateral adrenalectomy, all four patients showed complete clinical success. Five of 20 patients with bilateral aldosterone production according to AVS had a solitary adrenal nodule (8-19mm) on imaging. Two of these five patients were treated with unilateral adrenalectomy, neither having complete biochemical and/or clinical success postoperatively. Two of 16 patients younger than 35 years had discordant results, one with unilateral, and one with bilateral aldosterone production, according to AVS.Imaging studies inaccurately predicted laterality in a significant number of young patients with PA. In contrast to current clinical guidelines, our results support AVS for subtype evaluation in young adults with PA, including patients 35 years or younger.

Increasing Incidence of Primary Aldosteronism in Western Sweden During 3 Decades -Yet An Underdiagnosed Disorder
- 2021
-
In: Journal of Clinical Endocrinology & Metabolism. - : The Endocrine Society. - 0021-972X .- 1945-7197. ; 106:9
-
Journal article (peer-reviewed)abstract
- Context: Primary aldosteronism (PA) is the most common cause of secondary hypertension.Yet, the incidence of PA in the general population has not been studied. Objective: To estimate the incidence of PA in the general population. Design and methods: Patients who had received a diagnostic code for PA between 1987 and 2016 were identified in the Swedish National Patient Registry. Assessment of clinical and biochemical data was used to validate the diagnosis. The annual incidence of PA was calculated by using the number of inhabitants in the Vastra Gotaland County as a reference. Results: Of 570 identified patients, 473 (83%) had confirmed PA. Eligible for the incidence analysis were 416 patients, 248 (60%) men and 168 (40%) women, diagnosed with PA between 1987 and 2016. The mean (+/- standard deviation) age at diagnosis was 56 +/- 12 years. The median (interquartile range) annual incidence was 2 (1-2) cases per million between 1987 and 1996, 6 (4-9) cases per million between 1997 and 2006 and 17 (12-24) cases per million between 2007 and 2016. At the end of the study (December 31, 2016), 386 patients with confirmed PA were alive and living in the Vastra Gotaland County, giving a prevalence of 231 cases per million (0.022%). Conclusions: Despite increasing incidence, the proportion of patients identified with PA is lower than expected. Given the serious consequences of untreated PA, the noticeably low prevalence at the end of the study stresses the need to increase the awareness of PA among health care providers.

Journal article (peer-reviewed)abstract
- 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.We used national registers to identify patients diagnosed with PA between 1997 and 2019 (n=2419) and controls (n=24187) 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]).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.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.

Assessing Lateralization Index of Adrenal Venous Sampling for Surgical Indication in Primary Aldosteronism
- 2024
-
In: JOURNAL OF CLINICAL ENDOCRINOLOGY & METABOLISM. - 0021-972X .- 1945-7197.
-
Journal article (peer-reviewed)abstract
- Context Clinical practice guidelines recommend the lateralization index (LI) as the standard for determining surgical eligibility in primary aldosteronism (PA).Objective Our goal was to identify the optimal LI cutoffs 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 1550 patients with PA who underwent AVS, with and/or without adrenocorticotropin (ACTH) stimulation. The establishment of optimal cutoffs was informed by a survey of 82 patients with PA in Japan, aimed at determining the LI cutoff aligned with patient expectations for a surgical cure rate.Results The survey revealed that a median cure rate expectation of 80% would motivate patients with PA towards undergoing adrenalectomy. The optimal LI cutoffs 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 computed tomography imaging were identified as independent predictors of surgically curable PA. Incorporating these factors with the optimal LI cutoffs, 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.Conclusion The present study clarified the optimal LI cutoffs 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.

Journal article (peer-reviewed)abstract
- The burden of symptoms and treatment in patients with primary aldosteronism (PA), as well as the patients' experience of the health care is sparsely studied. The objectives of this study were to describe symptoms considered to be the most troublesome by patients with PA, and to explore health related worries and expectations following treatment.This was an explorative qualitative study where 25 patients with PA, diagnosed between 2017 and 2019, were included; 13 patients who had undergone adrenalectomy and 12 who were receiving medical treatment. Data was collected during six group interviews and analyzed using a thematic approach.Three main themes were identified: 1) Distress of the past, where the most important issues were struggle to receive a correct diagnosis, impaired well-being and the consumption of a large number of tablets, 2) Satisfaction after receiving a correct diagnosis, both in patients with unilateral and bilateral disease, but also dissatisfaction with lack of information about the disease, and 3) Future concerns, where worries about the long-term effects of PA on health in general dominated.Our findings illustrate several important issues related to PA where improvements in patient care are needed, including actions aiming at shortening the long diagnostic delay, a thorough information to the patients about the disease is of great importance, and that all patients with PA, regardless of treatment, would benefit from a structured long-term follow-up.

Journal article (peer-reviewed)abstract
- Treatment strategies for primary aldosteronism (PA) include unilateral adrenalectomy and medical treatment with mineralocorticoid receptor (MR) antagonists. Whether these two different treatment strategies are comparable in mitigating the detrimental effect of PA on outcomes is still debated.The primary aim of this systematic review is to identify, appraise and synthesise existing literature comparing clinical outcomes after treatment in patients with PA.A systematic and comprehensive search will be performed using PubMed, Web of Science and EMBASE, for studies published until December 2022. Observational and interventional studies will be eligible for inclusion. The quality of observational studies will be assessed using the Newcastle-Ottawa Scale, while interventional studies will be assessed using the Cochrane Effective Practice Organization of Care tool. The collected evidence will be narratively synthesised. We will perform meta-analysis to pool estimates from studies considered to be homogeneous. Reporting of the systematic review and meta-analysis will be in accordance with the Meta-analysis of Observational Studies in Epidemiology Preferred Reporting Items for Systematic reviews and Meta-Analysis guidelines.As this study is based solely on the published literature, no ethics approval is required. This review will aim to provide some estimates on outcomes, including survival, rates of clinical and biochemical control, cardiovascular and cerebrovascular events, as well as data on quality of life and renal function, in patients with PA treated surgically or with MR antagonists. The study findings will be presented at scientific meetings and will be published in an international peer-reviewed scientific journal.CRD42022362506.
