- Objective: Autoimmune polyendocrine syndrome type 1 (APS1) is a rare autosomal recessive disorder characterized by progressive organ-specific autoimmunity. There is scant information on APS1 in ethnic groups other than European Caucasians. We studied clinical aspects and autoimmune regulator (AIRE) gene mutations in a cohort of Indian APS1 patients. Design: Twenty-three patients (19 families) from six referral centres in India, diagnosed between 1996 and 2016, were followed for [median (range)] 4 (0.2-19) years. Methods: Clinical features, mortality, organ-specific autoantibodies and AIRE gene mutations were studied. Results: Patients varied widely in their age of presentation [3.5 (0.1-17) years] and number of clinical manifestations [5 (2-11)]. Despite genetic heterogeneity, the frequencies of the major APS1 components (mucocutaneous candidiasis: 96%; hypoparathyroidism: 91%; primary adrenal insufficiency: 55%) were similar to reports in European series. In contrast, primary hypothyroidism (23%) occurred more frequently and at an early age, while kerato-conjunctivitis, urticarial rash and autoimmune hepatitis were uncommon (9% each). Six (26%) patients died at a young age [5.8 (3-23) years] due to septicaemia, hepatic failure and adrenal/hypocalcaemic crisis from non-compliance/unexplained cause. Interferon-a and/or interleukin-22 antibodies were elevated in all 19 patients tested, including an asymptomatic infant. Eleven AIRE mutations were detected, the most common being p.C322fsX372 (haplotype frequency 37%). Four mutations were novel, while six others were previously described in European Caucasians. Conclusions: Indian APS1 patients exhibited considerable genetic heterogeneity and had highly variable clinical features. While the frequency of major manifestations was similar to that of European Caucasians, other features showed significant differences. A high mortality at a young age was observed.

- PURPOSE: Residual adrenocortical function, RAF, has recently been demonstrated in one-third of patients with autoimmune Addison's disease (AAD). Here, we set out to explore any influence of RAF on the levels of plasma metanephrines and any changes following stimulation with cosyntropin.METHODS: We included 50 patients with verified RAF and 20 patients without RAF who served as controls upon cosyntropin stimulation testing. The patients had abstained from glucocorticoid and fludrocortisone replacement > 18 and 24 h, respectively, prior to morning blood sampling. The samples were obtained before and 30 and 60 min after cosyntropin stimulation and analyzed for serum cortisol, plasma metanephrine (MN), and normetanephrine (NMN) by liquid-chromatography tandem-mass pectrometry (LC-MS/MS).RESULTS: Among the 70 patients with AAD, MN was detectable in 33%, 25%, and 26% at baseline, 30 min, and 60 min after cosyntropin stimulation, respectively. Patients with RAF were more likely to have detectable MN at baseline (p = 0.035) and at the time of 60 min (p = 0.048) compared to patients without RAF. There was a positive correlation between detectable MN and the level of cortisol at all time points (p = 0.02, p = 0.04, p < 0.001). No difference was noted for NMN levels, which remained within the normal reference ranges.CONCLUSION: Even very small amounts of endogenous cortisol production affect MN levels in patients with AAD.

- Context: Patients with Addison's disease (AD) self-report impairment in specific dimensions on well-being questionnaires. An AD-specific quality-of-life questionnaire (AddiQoL) was developed to aid evaluation of patients. Objective: We aimed to translate and determine construct validity, reliability, and concurrent validity of the AddiQoL questionnaire. Methods: After translation, the final versions were tested in AD patients from Norway (n = 107), Sweden (n = 101), Italy (n = 165), Germany (n = 200), and Poland (n = 50). Construct validity was examined by exploratory factor analysis and Rasch analysis, aiming at unidimensionality and fit to the Rasch model. Reliability was determined by Cronbach's coefficient-alpha and Person separation index. Longitudinal reliability was tested by differential item functioning in stable patient subgroups. Concurrent validity was examined in Norwegian (n = 101) and Swedish (n = 107) patients. Results: Exploratory factor analysis and Rasch analysis identified six items with poor psychometric properties. The 30 remaining items fitted the Rasch model and proved unidimensional, supported by appropriate item and person fit residuals and a nonsignificant chi(2) probability. Crohnbach's alpha-coefficient 0.93 and Person separation index 0.86 indicate high reliability. Longitudinal reliability was excellent. Correlation with Short Form-36 and Psychological General Well-Being Index scores was high. A shorter subscale comprising eight items also proved valid and reliable. Testing of AddiQoL-30 in this large patient cohort showed significantly worse scores with increasing age and inwomencompared with men but no difference between patients with isolated AD and those with concomitant diseases. Conclusion: The validation process resulted in a revised 30-item AddiQoL questionnaire and an eight-item AddiQoL short version with good psychometric properties and high reliability.

- OBJECTIVE: Autoimmune Addison's disease (AAD) entails a chronic adrenal insufficiency and is associated with an increased risk of severe infections. It is, however, unknown how patients with AAD were affected by the coronavirus disease 2019 (COVID-19) pandemic of 2020-2021. The aim of this study was to investigate the incidence of COVID-19 in patients with AAD in Sweden, the self-adjustment of medications during the disease, impact on social aspects and treatment during hospitalization. Additionally, we investigated if there were any possible risk factors for infection and hospitalization.DESIGN AND METHODS: Questionnaires were sent out from April to October 2021 to 813 adult patients with AAD in the Swedish Addison registry. The questionnaires included 55 questions inquiring about COVID-19 sickness, hospital care, medications, and co-morbidities, focusing on the pre-vaccine phase.RESULTS: Among the 615 included patients with AAD, COVID-19 was reported by 17% of which 8.5% required hospital care. Glucocorticoid treatment in hospitalized patients varied. For outpatients 85% increased their glucocorticoid dosage during sickness. Older age (p=0.002) and hypertension (p=0.014) were associated with an increased risk of hospital care while younger age (p<0.001) and less worry about infection (p=0.030) correlated with a higher risk of COVID-19.CONCLUSIONS: In the largest study to date examining AAD during the COVID-19 pandemic, we observed that although one fifth of the cohort contracted COVID-19 few patients required hospital care. A majority of the patients applied general recommended sick-rules despite reporting limited communication with healthcare during the pandemic.
