Addison's disease or primary adrenocortical deficiency results from destruction
of the adrenal cortex. Glucocorticoid, mineralocorticoid and sex steroid production
are all reduced.
It is a rare condition with a prevalence of 93-140 per million people and an annual incidence of 4.7-6.2 per million people in Western populations (1).
- in UK Addison’s disease affects around 1 in 10,000 individuals with an estimate of around 8400 currently diagnosed cases (2)
- according to a recent epidemiological study the incidence of Addison’s disease is on the rise (1)
- may occur at any age but commonly seen between the ages of 30-50 years (2)
- women are affected more than men (3)
Autoimmune adrenalitis accounts increasingly for the condition as tuberculosis
has become less common.
The disease may remain subclinical for a long period of time (4).
- primary and secondary adrenal
insufficiency share many clinical features - however, they differ in that only
primary adrenal insufficiency is characterized by mineralocorticoid deficiency
and by hyperpigmentation
