Lipidose hepática felina

Lipidose hepática felina

Abstract

ABSTRACT - Initially described as an idiopathic disease by Barsanti et al in 1977, feline hepatic lipidosis (FHL) is characterized as a current condition secondary to a primary process in over 95% of cases. This condition is more common in cats with high body condition subject to a prolonged period of food deprivation. The cats have a predisposition to the accumulation of triglycerides in the liver which, in case of disease, results in fat hepatocellular vacuolation. During the period of anorexia which they are subjected, lipolysis of fat from body stores will occur. Even though the physiopathological mechanisms that trigger this syndrome are not fully understood, there is an imbalance in the movement of fatty acids between the liver and adipose tissue, resulting in impairment of the ability to remove the fatty acids from the bloodstream by the liver. The aim of this study consisted in the characterization of a sample of seven cats diagnosed with feline hepatic lipidosis, given the predisposition of gender, age and weight. The clinical signs, physical and laboratory examinations were described for all patients. The cats were presented to consultation with a history of anorexia (71%), weight loss (57%), prostration (57%), constipation (57%) and vomiting, adipsia, and anuria with lower incidence. The period of anorexia was between seven to fifteen days, and the average was eleven days. Changes in the physical examination with the highest incidence were jaundice (71%), dehydration (71%), abdominal pain on palpation (43%) and dysphagia (14%). The complementary exams showed increased activity of liver enzymes and increased liver parenchyma hyperecogenecity was shown in the abdominal ultrasonography. The primary disease was diagnosed in five cases. The treatment was directed to the primary cause, in cases where it has been determined, and in other cases it directed the treatment for the disease likely. Of the seven cats in the study, treatment was successful in five cases and two cats were euthanized.

Inicialmente descrita como uma doença idiopática por Barsanti et al em 1977, a lipidose hepática felina (LHF) é caracterizada actualmente como uma patologia secundária a um processo primário em mais de 95% dos casos. Esta patologia é mais comum em gatos com condição corporal elevada sujeitos a um período prolongado de privação de alimento. Os gatos apresentam alguma predisposição para a acumulação de triglicéridos a nível hepático o que, em caso de doença, resulta em vacuolização gorda hepatocelular. Durante o período de anorexia ao qual estão sujeitos, vai ocorrer lipólise da gordura das reservas corporais. Apesar de os mecanismos fisiopatológicos que desencadeiam esta síndrome não serem completamente conhecidos, verifica-se um desequilíbrio na circulação de ácidos gordos entre o fígado e o tecido adiposo, resultando no comprometimento na capacidade de remoção dos ácidos gordos da corrente sanguínea por parte do fígado. O objectivo do estudo de casos consistiu na caracterização de uma amostra de sete gatos diagnosticados com lipidose hepática felina, atendendo à predisposição de género, idade e peso. Descreveram-se os sinais clínicos, físicos e laboratoriais de todos os pacientes. Os gatos analisados foram apresentados à consulta com história de anorexia (71%), perda de peso (57%), prostração (57%), obstipação (57%) e vómito, adipsia e anúria com menor incidência. O período de anorexia variou entre sete e quinze dias, tendo duração média de onze dias.
