Reporte de caso clínico: Hipotiroidismo en canino hembra de 4 años.

Abstract

Hypothyroidism is one of the most common endocrinopathies in canines, characterized by deficiency in the production or secretion of hormones T4 and T3 by the thyroid gland that presents as a multisystemic disease, and that´s why in most cases is underdiagnosed. This report explains the clinical case of a 4-year-old female mixed canine, who arrives at the clinic with a history of skin lesions for more than a year and a history of Ehrlichia canis. During the physical examination the patient presented physiological constants within the normal range, body condition 4/5, generalized skin lesions and grade 5/10 pruritus. General diagnostic tests were performed such as, blood panel, chem 10 or basic biochemical profile to measure glucose levels, creatinine, BUN (urea nitrogen), total proteins, ALT (alanine aminotrampherase), ALP (alkaline phosphatase), and more specific tests such as thyroid hormone measurement and lipid profile. The diagnosis was confirmed by the TSH (thyroid stimulating hormone) increased canine and T4 (thyroxine hormone) decreased accompanied by high levels of cholesterol and triglycerides. A therapeutic plan based on Thyrotabs® was managed in tablets of 0,1mg, this being the trade name and its active substance levothyroxine sodium, to regulate tyrosine levels with an initial dose of 20µg/kg every 12 hours for one month and further tests were performed to see the patient´s response to treatment and effectively with the initial dose it was possible to regulate TSH levels,T4, cholesterol and triglycerides.
