Pathophysiology description (narrative) Primary adrenal insufficiency most commonly results from autoimmune adrenalitis in adults in developed regions. The autoimmune process targets the adrenal cortex, leading to progressive destruction of steroid‑producing cells in zona glomerulosa and zona fasciculata, with resultant mineralocorticoid and glucocorticoid deficiency. The dominant autoantigen is 21‑hydroxylase (CYP21A2), recognized by circulating autoantibodies and autoreactive T cells. Histopathology shows mononuclear (lymphocyte/plasma cell/macrophage) infiltration, loss of normal zonation, and end‑stage cortical atrophy/fibrosis; clinical insufficiency appears after extensive loss of functional cortex. A Th1‑biased immune response with IFN‑γ supports cytotoxic T‑cell activation and B‑cell autoantibody production, and antibody‑dependent and complement‑mediated mechanisms may contribute to injury. Polygenic susceptibility is strong, driven by HLA class II haplotypes (DR3‑DQ2 and DR4‑DQ8) and non‑HLA immune‑regulatory genes (e.g., CTLA4, PTPN22, BACH2, CLEC16A, NLRP1, CIITA, STAT4). Monogenic APS‑1 (AIRE mutations) causes a breakdown of central tolerance, predisposing to Addison’s disease; patients with APS‑1 frequently develop AAD alongside other autoimmune features. Iatrogenic checkpoint blockade (CTLA‑4/PD‑1 inhibitors) can precipitate primary adrenal insufficiency by releasing peripheral checkpoint control and promoting anti‑adrenal autoimmunity, sometimes accompanied by adrenal autoantibodies. Many patients with autoimmune Addison’s retain some residual adrenocortical function for years, and natural history studies and staging frameworks describe progression from potential/subclinical phases (antibody‑positive) through impaired reserve to overt failure characterized by low cortisol and aldosterone, with high ACTH and renin. Clinical manifestations map to hormone loss: glucocorticoid deficiency causes fatigue, weight loss, hypotension, and hypoglycemia; mineralocorticoid deficiency causes hyponatremia, hyperkalemia, salt craving, and abdominal pain; hyperpigmentation reflects chronic ACTH/α‑MSH elevation in primary disease.

1) Core Pathophysiology - Primary mechanisms: Organ‑specific autoimmunity against steroidogenic enzymes (dominantly CYP21A2) with Th1‑biased CD4+ responses and HLA‑restricted cytotoxic CD8+ T‑cell effectors; humoral autoimmunity (21‑OHAbs) serves as biomarker and may contribute via ADCC/complement. Histology shows lymphocytic adrenalitis progressing to cortical atrophy/fibrosis.

Limitations and open questions - While 21‑OHAbs are highly specific and sensitive at onset, standardized performance metrics vary across assays and cohorts; residual function suggests heterogeneity in tissue destruction and potential windows for immunomodulation. Larger, diverse genetic studies are needed to refine non‑HLA loci and ancestry‑specific risks. (betterle2002autoimmuneadrenalinsufficiency pages 1-2, røyrvik2022thegeneticsof pages 11-12)

Conclusion Autoimmune Addison’s disease results from a confluence of genetic susceptibility (HLA and multiple immune‑regulatory loci), defects in immune tolerance (including AIRE in APS‑1), and effector immune mechanisms (Th1 polarization and HLA‑restricted cytotoxic CD8+ T cells) targeting adrenal steroidogenic cells, most prominently via 21‑hydroxylase. Clinical and laboratory phenotypes follow predictable hormonal deficits, and contemporary practice integrates serology (21‑OHAbs), dynamic testing (ACTH stimulation), and genetic/iatrogenic risk assessment (including checkpoint blockade) to diagnose and manage disease across its natural history. Ongoing research emphasizes early detection in antibody‑positive individuals, refinement of genetic risk, and exploration of targeted immunomodulation to preserve residual adrenal function.
