Background: Feline hyperthyroidism, the most common endocrinopathy in older cats, provides a spontaneous model for human thyrotoxicosis. Human thyrotoxicosis is associated with redox unbalance, which may result in organ damage. The redox status of hyperthyroid cats is largely unknown. The aims of...

This article aims at the presentation of polybrominated diphenyl ethers (PBDEs) involvement in feline hyperthyroidism, Hyperthyroidism is the most common endocrine disorder in cats. Last studies showed its high prevalence in middle-aged and senior animals. There are several risk factors associated...

Objectives: The objective of this study was to investigate serum cystatin C (sCysC) and urinary cystatin C (uCysC) in cats with hyperthyroidism and cats with feline immunodeficiency virus (FIV). Methods: Thirty cats with FIV, 26 hyperthyroid cats and 28 healthy cats were included. sCysC and...

Background: Hyperthyroidism is the most common endocrine disorder observed in domestic felines; however, its etiology is largely unknown. Two classes of persistent organic pollutants, polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) are known to interfere with thyroid...

Objectives: Hyperthyroidism is a disorder of older cats that may have a geographical variation in prevalence. Prevalence studies have not yet been performed in South Africa, a geographical area where hyperthyroidism in cats has recently been observed and where, reportedly, the incidence appears to...

Feline hyperthyroidism is a commonly diagnosed endocrinopathy that can have a substantial deleterious impact on the welfare of affected cats. This study aimed to estimate the prevalence, associated factors and geographical distribution for feline hyperthyroidism in England, using primary-care...

Objectives: This study sought to explore the clinicopathological features and comorbidities of cats with mild, moderate and severe hyperthyroidism in a radioiodine referral population. Methods: Medical records were reviewed, along with results of serum biochemistry, urinalysis, systolic blood...

Hyperthyroidism is the most commonly diagnosed feline endocrinopathy, diagnosed frequently in older cats. The incidence of hyperthyroidism has increased since its first description in 1979, and cats are now more often diagnosed at an early stage. Diagnosis and treatment can be challenging,...

Objectives: Present-day diagnosis of hyperthyroidism is often established in the early stages where clinical signs and physical examination findings typically associated with the disease may not yet be present. The purpose of this study was to investigate thyroid palpation score (TPS), total...

Background: In humans, measurement of serum thyroid-stimulating hormone (TSH) concentration is commonly used as a first-line discriminatory test of thyroid function. Recent reports indicate that canine TSH (cTSH) assays can be used to measure feline TSH and results can help diagnose or exclude ...
