Abstract: N Engl J Med. 2018 Jun 28;378(26):2543–2544.In brief: This article reviews important developments and major advances in characterizing autoimmunity in patients with autoimmune polyendocrine syndromes, such as the identification of new autoantibody targets associated with distinct diseases and their manifestations. The authors also provide an up to date review...

Brief summary: This study investigated the brain structure in young adult patients with autoimmune Addison’s disease (AAD). It found that patients with AAD had a 4.3% smaller total brain volume but no major differences in subcortical structures compared to healthy controls.Both short- and long-term disruptions in cortisol concentrations and rhythmicity affect brain structure development. Animal studies have shown that both pre- and postnatal disturb...

Brief Summary: This case-control study compared resting-state functional connectivity (rs-fc) of the brain between patients with autoimmune Addison’s disease (AAD) and healthy controls. The results suggest that AAD affects the baseline functional organization of the brain and that current treatment strategies of AAD may be a risk factor.Comment: Autoimmune Addison disease (AAD) is a form of primary adrenal insufficiency (PAI), in which autoimmune ad...

Brief Summary: This paper describes a novel ambulatory fraction collector that can be used with microdialysis to obtain high resolution steroid profiles over a 24-hour period.Comment: The natural circadian and ultradian secretion of adrenal hormones makes single timepoint measurements of these hormones uninformative for clinical decision making (1-3). Repeated sampling during the day requires admission into an atypical, and often disruptive, clinical set...

Nat Commun. 2021 Feb 11;12(1):959.https://pubmed.ncbi.nlm.nih.gov/33574239/The authors report a genome-wide association study (GWAS) of autoimmune Addison’s disease (AAD) in 1223 cases (defined as autoimmune adrenal failure plus positive serum autoantibodies against 21-hydroxylase) and 4097 healthy controls. Patients with APS-1 were identified and excluded. They identified 9 genome-wid...

Brief summary: The authors designed a polygenic risk score (PRS) to aid in estimating disease susceptibility in patients with autoimmune Addison’s disease (AAD).Autoimmune Addison’s disease (AAD) is the most common cause of primary adrenal insufficiency (PAI) in adults. Despite its exceptionally high heritability, tools to estimate disease susceptibility in individual patients are lacking (1–3). The aim of this study was t...
