Resumo
O hipertiroidismo felino é uma doença multifactorial resultante da produção e excreção excessiva de Tiroxina e Triiodotironina pela glândula tiróide considerando-se a doença endócrina mais comum do gato. Atualmente, são apontados diversos fatores de risco
que podem variar consoante a área geográfica em que são descritos. Alguns desses factores são: idade, tipo de alimentação e estilo de vida. O presente trabalho teve como objetivo
avaliar alguns dos fatores de risco desta doença na área metropolitana de Lisboa.
A amostra recolhida incluiu 44 animais hipertiroides apresentados à consulta no
Hospital Veterinário do Restelo, no período de 2014 a 2017. Foram também avaliados 44
animais saudáveis que constituiram o grupo controlo. Os factores de risco avaliados foram: idade, peso, raça, género, estado fértil, estilo de vida, tipo de alimentação, entre outros. Foram encontradas diferenças significativas entre os grupos apenas em relação à idade e ao peso (P<
0,01). Nos restantes factores de risco estudados, não foram encontradas diferenças significativas entre os grupos, provavelmente devido ao facto de os grupos em estudo se mostrarem demasiado heterogéneos.
Os animais hipertiroideus eram em geral mais velhos e leves que os animais
eutiroideus. Uma vez que não foram obtidos outros resultados estatisticamente significativos que permitam ser interpretados de forma conclusiva e tendo em conta a diferença de idades entre a população controlo e a polpulação de animais hipertiroideus, estes resultados não
devem ser considerados válidos nem devem ser generalizados para toda a população de gatos residentes na área da grande Lisboa.
Feline hyperthyroidism is a multifactorial disease resulting from the production and excessive excretion of Thyroxine and Triiodothyronine by the thyroid gland considering the most common endocrine disease of the cat. Currently, several risk factors are pointed out that may vary depending on the geographic area in which they are described. Some of these factors are: age, type of diet and lifestyle. The present study aimed to evaluate some of the risk factors of this disease in the metropolitan area of Lisbon. The sample included 44 hyperthyroid animals submitted to the consultation at the Veterinary Hospital of Restelo, from 2014 to 2017. Forty-four healthy animals that constituted the control group were also evaluated. The risk factors evaluated were: age, weight, gender, lifestyle and type of diet. Significant differences were found between the groups only in relation to weight (P< 0.01). In the other risk factors studied, no significant differences were found between the groups, probably due to the fact that the study groups were too heterogeneous. The hyperthyroid animals were generally lighter than the eutiroideus animals. Since no other statistically significant results have been obtained to be interpreted conclusively and taking into account the age difference between the control population and the polulation of hyperthyroid animals, these results should not be considered valid and should not be generalised to the entire population of cats residing in the greater Lisbon area.
