Hypothyreose: Ein Fall Hypothyroid Krankheit im Hund an ThePetCenter.com

HYPOTHYREOSE IM HUND

Hypothyreose im Hund, wo die Schilddrüsedrüse nicht normale Mengen des Schilddrüsenhormons absondert, die allgemeinste Drüsestörung im Hund ist. Die endokrinen Drüsen werden aufgelistet im folgenden…

Schilddrüse-Drüse (die Vorlagendrüse)
* Hypothalamus
* Pankreas
* Thymusdrüse
* Vorhergehendes pituitäres
* Pineal Drüse
* Testikel
* Eierstock
* Parathyreoid- Drüsen
* Hinteres pituitäres
* Nebennieren

Alle diese Gewebe sondern die chemischen Substanzen ab, die Hormone genannt werden, die einen profunden Effekt auf bestimmten „Ziel“ Geweben haben. Aber von allen jenen Drüsen und von Hormonen, gilt die Schilddrüsedrüse als die Vorlagendrüse. Wenn die Schilddrüsedrüse stört, wird jede Zelle im Körper beeinflußt. Keine Wunderhunde, richtig bestimmt mit Hypothyreose und auf passende Schilddrüsenhormonergänzungen gesetzt, schauen, zu fungieren und soviel zu glauben verbessern Sie als vor Behandlung.

ZEICHEN

Die meisten Hundeshowzeichen von Hypothyreose zwischen 3 und 5 Jahren des Alters aber Diagnose wird nicht in einigen Hunden gebildet, bis sie die Jahre älter sind. Männer und Frauen scheinen, gleichmäßig beeinflußt zu werden. Die Routineprüfung der jungen Hunde ist nicht allgemein erfolgt. Einige Tierärzte glauben daß, wenn ein Hund Hypothyreose nicht bis zum 5 oder 6 Jahren des Alters erworben hat, die Vorteile sind gut, daß es nie ein Problem für einzelnes das ist. (Katzen selten erwerben, Hypothyreose aber haben mehr Mühe mit Hyperthyreose, besonders ältere Katzen.)

Eins der am allgemeinsten gesehenen Zeichen, daß ein Hund unzulängliche Absonderung des Schilddrüsenhormons haben kann, ist Gewichtgewinn mit anscheinend wenig Nahrungsmitteleinlaß. Jedes überladene Haustier sollte auf Hypothyreose überprüft werden. (Sehen Sie diese Seite für Spitzen auf, wie man ein Haustier erhält, Gewicht.) in den althergebrachten Fällen dort zu verlieren ist häufig Mangel an korrektem Haarmantel und gleichmäßigem Haarverlust. This loss generally displays a pattern over the lumbar area on both sides, sparse hairs on the back of the rear legs and lack of hair along the abdomen. The coat tends to lack luster and the finer hairs of the undercoat may be missing entirely. Most dogs with hypothyroidism lack energy, prefer warm environments and have poor exercise tolerance. Of great concern to breeders is the fact that dogs with hypothyroidism may be infertile and many breeders have their dogs tested for thyroid function prior to breeding; in dogs with a poor breeding history, hypothyroidism often is the culprit.

Hypothyroidism is rare in toy and miniature breeds of dogs. Research definitely indicates that most hypothyroid cases are inherited. In fact it is fairly common in certain breeds such as…

* Golden Retrievers
* Doberman pinschers
* Greyhounds
* Irish Setters
* Dachshunds
* Cocker Spaniels
* Shetland Sheepdog
* Boxer
* English Setter

DIAGNOSIS

If the physical exam or history indicates probable Hypothyroidism, the veterinarian will take a blood sample and have one or more tests run. The most common tests for thyroid function are T4 (the main Thyroid hormone) and canine TSH (Thyroid Stimulating Hormone from the Pituitary Gland). Some veterinary laboratories now recommend TgAA (Thyroglobin Auto-antibody) analysis be done because it identifies thyroiditis much earlier in the progression of the disease. All of these assays are relatively inexpensive, and the information they provide in invaluable to establishing a diagnosis. University Veterinary Medical Colleges such as the U. of Illinois and Michigan State University have state of the art diagnostic instrumentation that have advanced the ability and accuracy of local veterinarians attempts to establish the presence of hypothyroidism in their patients.

TREATMENT

L-thyroxine (T4) tablets are generally administered twice a day. When given twice a day, most veterinarians prescribe 0.1 mg/10 pounds twice per day as the initial dosage. Repeat exams and occasional follow-up blood testing really helps to fine tune the proper amount of medication needed for each patient.

Is hypothyroidism inherited? Evidence indicates some familial patterns of inheritance. There are more than half a dozen studies reporting the familial incidence of autoimmune thyroiditis. Much of the research on hypothyroidism is dogs has been done at Michigan State University Veterinary School.

Not all cases of hypothyroidism are due to autoimmune lymphocytic infiltration of the gland. There can be other “inducers” of the disease such as consumption of too much Iodine. These inducers can be very difficult to identify.

Humans may acquire what is called Hashimoto’s Disease, a genetically transmitted form of hypothyroidism but this disease is not the same as autoimmune thyroiditis in dogs. In Hashimoto’s Disease females are five times more likely to get the disease than males. There are other differences, as well.

CANINE HYPOTHYROIDISM: CASE PRESENTATION

The following case represents a fairly atypical case of hypothyroidism in that most cases are identified prior to such advanced skin and coat signs. The dog had been treated for non-specific allergies, and in fact does some allergic problems and skin scarring due to chronic inflammation of the skin. However, once the Hypothyroidism was discovered and proper treatment instituted, the allergic conditions were less severe simply because the skin became much healthier and more resistant to infections, irritants and allergens.

This is how a dog recently looked when presented… Hypothyroidism was suspected and the blood values of thyroid hormone supported the presumptive diagnosis. The dog was placed on Soloxine in early June, 2001 and the photos in the second row show the improvement in her after six weeks on medication. You can see what a change can occur when a diagnosis of Hypothyroidism is made and proper therapy instituted. The dog’s owners report excellent new growth of hair, renewed vigor and weight loss… all improvements!
