Subjective health status in Norwegian patients with Addison's disease.
OBJECTIVE
Many patients with Addison's disease have complaints that might be related to the disease or to its treatment. However, only a few studies have addressed the subjective health status of patients with adrenocortical failure. The aim of the present study was to assess the subjective health status with special emphasis on fatigue among patients with Addison's disease. SUBJECTS, DESIGN AND MEASUREMENT: In a postal survey, 79 patients with confirmed primary adrenal failure (Addison's disease) completed the Short Form 36 (SF-36) and the Fatigue questionnaires. The subjective health status in Addison's disease was compared with normative data from the general population.


RESULTS
General health and vitality perception were most consistently impaired in the patients with Addison's disease. The scores on physical functioning and role-physical were low in women. Social functioning and role-emotional scores were also lower than normal in the female patients, but this was confined to the patients with autoimmune polyendocrine syndromes. Patients with autoimmune polyendocrine syndromes tended to have lower scores than patients with solitary Addison's disease. The level of fatigue was higher than normal for both men and women. Working disability at ages 18-67 years was 26%, compared with 10% in the corresponding general Norwegian population. The high working disability increased with age and was higher in subgroups with concomitant endocrine diseases. Most subjective health parameters were lower among the disabled compared to the patients in work.


CONCLUSIONS
Patients with Addison's disease under replacement therapy with cortisone acetate and fludrocortisone have reduced general health perception and vitality, and increased fatigue. Female patients reported reduced physical function, which might be due to adrenal androgen depletion. Mental health seems more influenced by concomitant endocrine diseases, but mental fatigue might be a specific feature in adrenal failure. The patient population is heterogeneous, with normal findings in a substantial proportion but markedly reduced subjective health status and working ability in many others. Thus, there might be potential for further refinement of replacement therapy.
