Long-term remission of candidiasis with fermented lingonberry mouth rinse in an adult patient with APECED

We report a long-term remission in candidiasis in a 57-year-old Finnish female with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) suffering from recurrent oral, esophageal, gastric, vaginal, and anal candidiasis since childhood. Candidiasis treatment with antifungal medicines fluconazole, itraconazole, posaconazole, voriconazole, caspofungin, nystatin, or amphotericin-B during 2008-2021 had variable effects and intermittent development of antifungal resistance and hospital periods. The patient started using fermented lingonberry juice (FLJ) as a mouth rinse daily in April 2021. No symptoms or mucosal signs of candidiasis in any part of the digestive system or vaginal area have been noticed during this exceptionally long-term 2 ½ year remission in candidiasis without antifungal medications.
