Primary hypoadrenocorticism was diagnosed in ten young to middle-aged cats of mixed breeding. Five of the cats were male, and five were female. Historic signs included lethargy (n = 10), anorexia (n = 10), weight loss (n = 9), vomiting (n = 4), and polyuria (n = 3). Dehydration (n = 9), hypothermia (n = 8), prolonged capillary refill time (n = 5), weak pulse (n = 5), collapse (n = 3), and sinus bradycardia (n = 2) were found on physical examination. Results of initial laboratory tests revealed anemia (n = 3), absolute lymphocytosis (n = 2), absolute eosinophilia (n = 1), and azotemia and hyperphosphatemia (n = 10). Serum electrolyte changes included hyponatremia (n = 10), hyperkalemia (n = 9), hypochloremia (n = 9), and hypercalcemia (n = 1). The diagnosis of primary adrenocortical insufficiency was established on the basis of results of adrenocorticotropic hormone (ACTH) stimulation tests (n = 10) and endogenous plasma ACTH determinations (n = 7). Initial therapy for hypoadrenocorticism included intravenous administration of 0.9% saline and dexamethasone and intramuscular administration of desoxycorticosterone acetate in oil. Three cats were euthanatized shortly after diagnosis because of poor clinical response. Results of necropsy examination were unremarkable except for complete destruction of both adrenal cortices. Seven cats were treated chronically with oral prednisone or intramuscular methylprednisolone acetate for glucocorticoid supplementation and with oral fludrocortisone acetate or intramuscular injections of repository desoxycorticosterone pivalate for mineralocorticoid replacement. One cat died after 47 days of therapy from unknown causes; the other six cats are still alive and well after 3 to 70 months of treatment.

The present prospective observational study was designed to assess the prevalence of hemodialysis in type 2 diabetic patients with an impairment of plasma aldosterone responsiveness to adrenocorticotropic hormone (ACTH). Sixty seven patients (43 men and 24 women) were selected. The inclusion criteria were age < 65 years; presence of normoalbuminemia (serum albumin > 3.6 g/dl); and absence of azotemia (serum creatinine < or = 1.2 mg/dl in males, and < or = 1.0 mg/dl in females). Soluble alpha(1-24)-ACTH was injected intramuscularly in a single dose of 0.25 mg after overnight recumbency. The area under the aldosterone curve (aldosterone AUC) was calculated. The diabetic patients were divided into two groups according to the levels of aldosterone AUC. Patients with an aldosterone AUC in the range of 0-381 were considered poor responders (n = 31) and those with an AUC of 397-1,007 were considered good responders (n = 36). The follow-up was performed during a 144-month period. The end point of the study was the introduction of hemodialysis. A total of 14 patients (12 poor responders and 2 good responders; p < 0.001) were introduced to hemodialysis. The prevalence of hemodialysis in the poor responders (5.74 per 100 patient-years) was significantly higher (p < 0.001, log-rank test) than that in the good responders (0.68 per 100 patient-years). One possible explanation is that an inappropriate level of salt intake relative to the impaired plasma aldosterone control may have contributed to the high prevalence of risks and hemodialysis in the poor responders.

Hypoadrenocorticism (Addison disease) is an uncommon condition in dogs and even more rare in cats. Hypoadrenocorticism is most often caused by immune-mediated destruction of the adrenal glands resulting in decreased mineralocorticoid and glucocorticoid production. Although less common, some dogs with hypoadrenocorticism have normal serum electrolytes. Hypoadrenocorticism causes a wide variety of clinical symptoms including gastrointestinal upset, weakness, weight loss, and hypovolemia. Laboratory and diagnostic findings vary, but classic abnormalities include hyperkalemia, hyponatremia, azotemia, anemia, and lack of a stress leukogram. However, many other diseases present with similar symptoms and diagnostic findings. Definitive diagnosis requires adrenocorticotropic hormone (ACTH) stimulation testing to demonstrate low basal and post-ACTH cortisol levels. In some cases, ACTH level or basal- and ACTH-stimulated aldosterone levels must also be measured. The prognosis for hypoadrenocorticism is good with appropriate mineralocorticoid and glucocorticoid supplementation.
