Pituitary pars intermedia dysfunction (PPID), or equine Cushing's disease, is an endocrine disease affecting the pituitary gland of horses. It is most commonly seen in older animals, [ 1 ] and is classically associated with the formation of a long, wavy coat ( hirsutism ) and chronic laminitis .
Cushing's syndrome is a collection of signs and symptoms due to prolonged exposure to glucocorticoids such as cortisol. [4] [9] [10] Signs and symptoms may include high blood pressure, abdominal obesity but with thin arms and legs, reddish stretch marks, a round red face due to facial plethora, [11] a fat lump between the shoulders, weak muscles, weak bones, acne, and fragile skin that heals ...
Horses are best managed by only allowing short grazing periods—less than 1 hour since they can rapidly ingest grass, [18] or confining them to a limited turn-out area or by use of a grazing muzzle. Horses with severe IR, that have recurrent laminitis, are not recommended to return to pasture. Hay low in NSC is provided in place of pasture.
Cushing syndrome symptoms. Not everyone has the same symptoms with Cushing syndrome, but the Cleveland Clinic says they may include: Rapid weight gain in the face, abdomen, back of the neck, and chest
The symptoms of Cushing's disease are similar to those seen in other causes of Cushing's syndrome. [5] Patients with Cushing's disease usually present with one or more signs and symptoms secondary to the presence of excess cortisol or ACTH. [6] Although uncommon, some patients with Cushing's disease have large pituitary tumors (macroadenomas).
Cushing's is an umbrella term for conditions caused by elevated cortisol and adrenocorticotropic hormone levels. Cushing's disease most commonly refers to pituitary-dependent hyperadrenocorticism, the most common condition of Cushing's syndrome, but 'Cushing's' is used to refer to all hyperadrenocorticism conditions. [2]
Myxomas may also occur outside the heart, usually in the skin and breast. Endocrine tumors may manifest as disorders such as Cushing syndrome. The most common endocrine gland manifestation is an ACTH-independent Cushing's syndrome due to primary pigmented nodular adrenocortical disease (PPNAD). [5]
Pseudohyperaldosteronism (also pseudoaldosteronism) is a medical condition which mimics the effects of elevated aldosterone (hyperaldosteronism) by presenting with high blood pressure, low blood potassium levels (hypokalemia), metabolic alkalosis, and low levels of plasma renin activity (PRA).
