Pathological changes of the adrenal glands (including adrenal atrophy) are combined with fatigue, hypotension, weight loss and hyper skin pigmentation (Mitchell & Pearce, 2012). The steroidogenic enzymes in the adrenal cortex of the patient with Addison’s disease become targets for the immune system to attack (Mitchell & Pearce, 2012). The presence of circulating steroid 21-hydroxylase antibodies is a reliable predictor of Addison’s Disease, this is normally located on the smooth endoplasmic reticulum of intact cells (Mitchell & Pearce, 2012). This can lead to other autoimmune responses in the body, metastatic malignancy, amyloidosis, hemorrhage, infections, adrenoleuko dystrophy, or sarcoidosis. Other clinical manifestations include low levels of cortisol in serum and urine tests, increased ACTH levels, BUN increases (due to dehydration), Eosinophil and lymphocyte elevations, hyperkalemia and mild alkalosis (Huether & McCance, 2017). Treatment involves glucocorticoid and mineralocorticoid replacement for life as well as increases in sodium intake if patient experiences excessive sweating and diarrhea.
