Abstract

Hyperthyroidism is the most common endocrinopathy in cats of middle and old age. This pathology leads to a sharp increase in the level of metabolism, secondary damage to the heart, blood vessels, liver, kidneys and nervous system. The purpose of this study was to study the aspects of diagnosing hyperthyroidism in cats, as well as testing the complex correction scheme for this pathological condition. It was found that in cats with hyperthyroidism, the most common symptoms were weight loss, cachexia of alopecia and ruffled hair (92,8%), hyperactivity, anxiety and excitement of the central nervous system (85,7%), enlargement of the thyroid gland, excessive claw growth and deformation and hyperrexia (78,5%), cardiac murmurs, diarrhea or bulky stools (64,3%), high arterial hypertension (systolic blood pressure over 200 mm Hg; diastolic blood pressure over 120 mm Hg .st), polydipsia and polyuria (57,1%); less commonly, tachypnea and shortness of breath (50,0%), arrhythmia (42,9%), aggression and tachycardia (35,7%), vomiting (28,6%); rarely, ventroflexion (21,4%), weakness (14,3%), drowsiness, depression, and anorexia (7,1%). An increase in hematocrit, erythrocyte sedimentation rate, red blood cell count, and hemoglobin concentration was found in the peripheral blood of cats with hyperthyroidism. Biochemical analysis of blood serum in patients with feline hyperthyroidism found a significant increase in the concentration of levothyroxine, urea, creatinine, cholesterol, triglycerides, the activity of alanine, aspartic aminotransferases and alkaline phosphatase. Combined therapy with tyrosol, amlodipine, maropitant, ipakitine, infusion therapy, and dietary food Renal Royal Canine allowed 71,4% of cats with hyperthyroidism to achieve a significant improvement in their general condition, and in 14,2%, a stable remission of the disease.
