Abstract

Background: Autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED) is a rare inborn immune error characterized by a triad of chronic mucocutaneous candidiasis (CMC), hypoparathyroidism (HP), and adrenal insufficiency (ADI). Methods: Literature search was conducted in PubMed, Web of Science, and Scopus databases using related keywords, and included studies were systematically evaluated. Results: We reviewed 938 APECED patients and the classic triad of APECED was detected in 57.3% (460 of 803) of patients. CMC (82.5%) was reported as the earliest, HP (84.2%) as the most prevalent, and ADI (72.2%) as the latest presentation within the classic triad. A broad spectrum of non-triad involvements has also been reported; mainly included ectodermal dystrophy (64.5%), infections (58.7%), gastrointestinal disorders (52.0%), gonadal failure (42.0%), neurologic involvements (36.4%), and ocular manifestations (34.3%). A significant positive correlation was detected between certain tissue-specific autoantibodies and particular manifestations including ADI and HP. Neutralizing autoantibodies were detected in at least 60.0% of patients. Nonsense and/or frameshift insertion-deletion mutations were detected in 73.8% of patients with CMC, 70.9% of patients with HP, and 74.6% of patients with primary ADI. Conclusion: Besides penetrance diversity, our review revealed a diverse affected ethnicity (mainly from Italy followed by Finland and Ireland). APECED can initially present in adolescence as 5.2% of the patients were older than 18 years at the disease onset. According to the variety of clinical conditions, which in the majority of patients appear gradually over time, clinical management deserves a separate analysis. © 2021 Informa UK Limited, trading as Taylor & Francis Group.
