What causes PPID in horses

PPID is caused by degeneration of neurons that affect the production of hormones such as adrenocorticotrophic hormone (ACTH). Common clinical signs include a long, curly hair coat, delayed shedding, loss of muscle, poor immune function, and laminitis

Can PPID be prevented?

It is not possible to prevent this condition. However, with available blood tests we are now able to recognize and treat more cases earlier and more effectively and many treated horses and ponies go on to live normal lives for many years after diagnosis and treatment.

Is PPID in horses genetic?

The precise cause of PPID is still unknown, but It’s likely there are several factors that cause the neurodegeneration that leads to PPID, including oxidative stress, metabolic factors e.g. EMS, toxins, chronic stress, and there may be a genetic predisposition.

How do you prevent Cushing's disease in horses?

Although Cushing’s disease cannot always be prevented, there are precautions you can take to lower the risk. “The most important thing is to keep your horse’s weight down, providing proper nutrition, which means to feed him only what he really needs,” Langer says. Sugar intake should be minimized.

How common is PPID in horses?

What is PPID? Pituitary pars intermedia dysfunction (PPID; equine Cushing’s disease) is an endocrine disorder that occurs in over 20% of aged horses, ponies, and donkeys. Most animals are over 15 years old when diagnosed, but PPID can occur in younger horses. It is, rare in horses less than 10 years old.

How is PPID diagnosed?

Thyrotropin releasing hormone stimulation test (TRHST) This is currently considered the most accurate test for the diagnosis of PPID. The test relies on an excessive pituitary response to the administration of Thyrotropin-releasing hormone (TRH) in horses with PPID when compared to normal horses.

What should I feed my horse with PPID?

Horses and ponies diagnosed with PPID/Cushing’s Disease should be fed a low sugar and starch diet. As alfalfa is naturally low in both sugar and starch, there are a number of feeds in our range that are suitable.

What should a horse with Cushings not eat?

Feeding Horses with Cushing’s Disease These horses are often insulin resistant and have high blood sugar levels so non-structured carbohydrates (NSC) need to be avoided. Feeds low in soluble carbohydrates (sugar and starch or NSC) are recommended.

Does a horse with Cushings need medication?

A horse with Cushings Disease will require treatment for its entire life. Although the treatment we can give is effective, many horses will still suffer from recurrent laminitis. However, early and effective treatment can give your horse a new lease of life, which can remain for many years.

Should you ride a horse with Cushings?

You should first consult with your veterinarian before beginning an exercise or riding program. However, generally speaking, horses with Cushing’s can be ridden like any other horse, particularly if the Cushing’s syndrome is well controlled with medication.

Why does PPID cause PU PD?

Polyuria and Polydipsia Horses with pituitary pars intermedia dysfunction (PPID) or equine metabolic syndrome (EMS) have PU/PD because of hypercortisolemia and hyperglycemia that may exceed renal threshold. Cortisol inhibits ADH, resulting in increased output of dilute urine.

What does the pars intermedia secrete?

The most obvious function of the pars intermedia in lower vertebrates is the secretion of melanocyte-stimulating hormone (MSH) for the purpose of pigmentary control.

Where is the pituitary gland in horses?

The major endocrine glands in the horse. The pituitary gland is located near the center and bottom of the brain. It produces a number of critical hormones that control many parts of the body, including several other endocrine glands.

What are the first signs of Cushing's disease in horses?

Clinical signs include increased coat length and delayed shedding of the winter coat, laminitis, lethargy, increased sweating, weight loss and excessive drinking and urinating. The disease primarily affects those over the age of 10, with 19 being the average age at diagnosis.

When should you test for PPID?

At the time of diagnosis, horses with PPID are >15 years of age, and usually older than 20 years. The typical clinical signs include hirsutism, loss of muscle, and accumulation of fat in the neck. Insulin resistance is common and some horses may develop diabetes mellitus. There is susceptibility for laminitis.

Can a horse with Cushings have alfalfa?

Alfalfa can be a good option for a horse with Cushings if they are a hard time holding their weight because it is more calorie-dense than grass hay.

Can a horse have PPID and EMS at the same time?

Discovering novel therapies is an exciting area of research, as there is a critical need for safer and more effective means of treating both the insulin resistance and inflammatory component of EMS. Occasionally, both disorders can occur together. PPID horses can also be IR, but EMS horses are less likely to be PPID.

How do you treat insulin resistance in horses?

The best way to treat insulin resistance is to prevent it in the first place. This can be done by feeding a proper diet, ensuring your horse gets plenty of exercise and maintaining a healthy body condition score of 5-6.

What is the life expectancy of a horse with Cushings?

Vets encourage owners of Cushing’s horses to decrease the amount of carbohydrates they feed (e.g., grains or other concentrates), maintain the horse at a healthy body condition score, and ensure his diet is properly balanced. Well-managed horses should live about five to seven years or more past diagnosis.

What happens if Cushing's is left untreated in horses?

If a horse has untreated Cushing’s Disease, it is more likely to develop laminitis and the laminitis will be more difficult to control. If an equine has any of the clinical signs suggestive of Cushing’s, a blood sample can be taken to check ACTH levels in the blood.

Can a horse with Cushings have a foal?

Mares can successfully conceive and foal well into their third decade of life.

Can horses with Cushing's eat carrots?

Unfortunately most commercially made horse treats, as well as apples and carrots, can be high in sugar. This presents a problem with horses that have Cushing’s disease, or Insulin Resistance/Metabolic Syndrome, as those horses’ sugar and starch intake must be limited.

Can you ride a horse with PPID?

Sick horse, can’t ride, right? Not necessarily. Perhaps because PPID has historically been classified as a “senior horse disease,” the notion lingers that these horses should be retired after diagnosis.

Is Cushings a death sentence?

Cushing’s disease is not a death sentence. Despite the fact that there is no cure, there are several management practices that can keep an affected horse in use and in good health for many years following diagnosis.

It usually takes between 6-12 weeks to see a clinical benefit of treatment, although in some unusual cases it can sometimes take several years before a benefit is seen.

How often should a horse urinate?

A lot. Horses typically produce several quarts of urine every four hours, for a total of about 1.5 to 2 gallons per day. (By contrast, an adult male human pees 1 or 2 quarts per day.)

What is horse Polydipsia?

Polydipsia (PD) in adult horses can be defined as water intake >100 ml/kg daily (>10% BWT) although under UK management and environmental conditions it is probable when intake is > 70 ml/kg daily (>7% BWT).

What hormones does pars nervosa release?

These neurons project to the pars nervosa, where they release the neuroendocrine hormones oxytocin and arginine vasopressin (AVP) into the systemic circulation via fenestrated sinusoidal capillaries.
