Adrenal insufficiency and the use of mineralocorticoid treatment in male patients with adrenoleukodystrophy; a retrospective analysis of an institutional database.

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.

Best Practice Alert to Promote Screening for Primary Aldosteronism Among People With Apparent Treatment-Resistant Hypertension.

OBJECTIVE: Guidelines recommend screening all individuals with resistant hypertension for primary aldosteronism (PA) but less than 2% are screened. We aimed to develop a noninterruptive Best Practice Alert (BPA) to assess if its implementation in the electronic health record improved PA screening rates among individuals with apparent treatment-resistant hypertension (aTRH). METHODS: We implemented a noninterruptive BPA on 9/17/2022 at our ambulatory primary care, endocrinology, nephrology, and cardiology clinics. We assessed clinical parameters of people with aTRH before (9/17/2021-9/16/2022) and after (9/17/2022-9/16/2023) the BPA was implemented. The noninterruptive BPA embedded with an order set identified people with aTRH and recommended screening for PA if it was not previously performed. RESULTS: There were 10 944 and 11 463 people with aTRH who attended office visits during the 12 months before and after the BPA implementation, respectively. There were no statistically significant differences in median age (P = .096), sex (P = .577), race (P = .753), and ethnicity (P = .472) between the pre- and post-BPA implementation groups. There was a significant increase in PA screening orders placed (227 [2.1%] vs 476 [4.2%], P < .001) and PA screening labs performed (169 [1.5%] vs 382 [3.3, P < .001) after BPA implementation. PA screening tests were positive in 26% (44/169) and 23% (88/382) of people in the pre- and post-BPA groups, respectively (P = .447). CONCLUSION: Implementation of a real-time electronic health record BPA doubled the screening rate for PA among people with aTRH; however, the overall screening rate was low.
