Health-Related Quality of Life in Patients with Primary Adrenal Insufficiency.

(1) Background: Patients with primary adrenal insufficiency (PAI) suffer from a reduced quality of life. However, clinical factors associated with this impairment remain unclear. The aim of this study was to assess the health-related quality of life (HRQoL) and to evaluate the associations with clinical and hormonal parameters in a group of patients with PAI. (2) Methods: The study included 32 patients with autoimmune PAI, who answered the quality of life in Addison's disease questionnaire (AddiQoL). Clinical data and hormonal measurements were collected from the patients. (3) Results: The total AddiQoL score of males was significantly higher than that of females ( p = 0.011). Furthermore, males reached significantly higher scores in each of the four subscales (fatigue- p = 0.013, emotional sphere- p = 0.048, adrenal insufficiency symptoms- p = 0.039, and miscellaneous questions- p = 0.034). There was a negative correlation between HRQoL and gonadotropin levels (FSH and fatigue r = (-)0.38, p = 0.032; FSH and emotional sphere r = (-)0.416, p = 0.018). This study found no significant associations between AddiQoL scores and the presence of autoimmune comorbidities; only fatigue scores were worse in the presence of autoimmune thyroiditis ( p = 0.034). The doses of hydrocortisone and fludrocortisone in the replacement therapy were not associated with AddiQoL scores. AddiQoL scores correlated negatively with the age of diagnosis ( p = 0.015). (4) Conclusions: Female sex, higher gonadotropins level, and older age at diagnosis were associated with impaired HRQoL in the studied group of patients with PAI.
