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.
肾上腺皮质功能减退症(艾迪生病)在犬中并不常见,在猫中更为罕见。肾上腺皮质功能减退症最常见的病因是免疫介导的肾上腺破坏,导致盐皮质激素和糖皮质激素分泌减少。虽然不太常见,但一些患有肾上腺皮质功能减退症的犬血清电解质正常。肾上腺皮质功能减退症会引发多种临床症状,包括胃肠道不适、虚弱、体重减轻和血容量减少。实验室检查和诊断结果各不相同,但典型异常包括高钾血症、低钠血症、氮质血症、贫血以及缺乏应激白细胞象。然而,许多其他疾病也会出现类似症状和诊断结果。确诊需要进行促肾上腺皮质激素(ACTH)刺激试验,以证明基础和ACTH刺激后的皮质醇水平较低。在某些情况下,还必须测量ACTH水平或基础及ACTH刺激后的醛固酮水平。通过适当补充盐皮质激素和糖皮质激素,肾上腺皮质功能减退症的预后良好。
