Haemostatic abnormalities in cats with naturally occurring liver diseases.
Alterations in the haemostatic system were characterized in cats with different naturally occurring liver diseases. The study looked at 44 healthy cats and 45 cats with different liver diseases confirmed histologically or cytologically (neoplasia, n=9; inflammation, n=12; hepatic lipidosis, n=13; other degenerative liver diseases, n=11). The following parameters were evaluated: platelet count; prothrombin time; activated partial thromboplastin time; thrombin time; factor (F) II, FV, FVII, FX, and FXIII activities; fibrinogen concentration; activities of antithrombin, protein C, plasminogen, and α(2)-plasmin inhibitor, and D-dimer concentration. In cats with liver diseases, 44/45 (98%) had one or more abnormalities of the coagulation parameters measured. In cats with inflammatory liver diseases, increased D-dimer concentrations and decreased FXIII activity were the most consistent abnormalities and were found in 83% and 75% of cats, respectively. The most common abnormality in cats with neoplastic liver disease was FXIII deficiency (78%). The most consistent abnormalities in cats with hepatic lipidosis were increased FV activity and D-dimer concentration with 54% of cats having values above the reference range for both parameters. Cats with miscellaneous degenerative liver disease most frequently showed FXIII deficiency (64%). The results of this study show that alterations of single haemostatic components are a frequent finding in cats with liver disease. Activation of haemostasis with subsequent consumptive coagulopathy (rather than decreased synthesis) seems to be responsible for these alterations. Increased blood levels of different haemostatic components in cats with inflammatory lesions may be related to an acute phase reaction.
Canine ehrlichiosis has emerged as one of the most clinically important tick-borne diseases affecting dogs. Eighty-five naturally infected dogs have been investigated, the most consistent clinical signs recorded were fever, emaciation and lymphoadenopathy, anemia, monocytosis, thrompocytopenia, hypoalbuminemia, elevation in liver enzymes and total bilirubin were the most remarkable changes asso...متن کامل
Survey of polycystic kidney disease and other urinary tract abnormalities using ultrasonography in Persian and Persian related cats in Iran
Ultrasonography is an accurate and accessible method for detecting polycystic kidney disease (PKD), an inherited autosomal dominant disease, and other urinary tract diseases. The present work is a preliminary study of PKD and urinary tract abnormalities using ultrasonography in Persian and other long hair cats in Iran. This study was conducted on 83 cats including 68 Persian cats and 15 Persian...متن کامل
The Effect of Naturally Occurring Chronic Kidney Disease on the Micro-Structural and Mechanical Properties of Bone
Chronic kidney disease (CKD) is a growing public health concern worldwide, and is associated with marked increase of bone fragility. Previous studies assessing the effect of CKD on bone quality were based on biopsies from human patients or on laboratory animal models. Such studies provide information of limited relevance due to the small size of the samples (biopsies) or the non-physiologic CKD...متن کامل
An evaluation of some oxidative and enzymatic biomarkers in different stages of naturally occurring copper poisoning in sheep
BACKGROUND: The early stage of Copper poisoning is difficult to be clinically diagnosed in sheep and has not been documented clearly yet. OBJECTIVES: To assess biomarkers in predicting early Copper poisoning in sheep, blood samples were collected from several groups of animals from a naturally Copper poisoning occurrence in an industrial region. METHODS: Animals were divided into four experimen...متن کامل
BACKGROUND Duration of survival of cats with naturally occurring chronic kidney disease (CKD) is poorly characterized. HYPOTHESIS Stage of kidney disease based on serum creatinine concentration (SCr) at the time of diagnosis and after correction of prerenal azotemia is strongly associated with duration of survival in cats. ANIMALS Two hundred and eleven client-owned cats with naturally occu...متن کامل
