Abstract
OBJECTIVE To describe the therapeutic protocol used to normalize severe hypertriglyceridemia in a dog. CASE SUMMARY A 7-month-old, 1.2-kg female Pomeranian presented with acute polyuria, polydipsia, and ocular discoloration. Diagnoses included diabetic ketosis, severe hypertriglyceridemia (>225 mmol/L [>20,000 mg/dl]), lipemia retinalis, and bilateral uveitis. The triglyceride concentration was near normal within 2 days of initiating treatment with fenofibrate, regular insulin constant rate infusion (CRI), manual therapeutic plasma exchange (TPE), and a low-fat diet. All clinical signs resolved. The dog has had no relapse of hypertriglyceridemia at the time of writing the manuscript, 6 months later, with continued treatment of diabetes mellitus. NEW OR UNIQUE INFORMATION PROVIDED This is the first case report documenting the combination of fenofibrate, insulin CRI, and manual TPE for treatment of severe hyperlipidemia in a dog. Detailed protocols for manual TPE and a novel insulin CRI are provided. A discussion of multiple spurious biochemical and hematologic errors associated with the severe hypertriglyceridemia is also provided.

Tan AWK, Epstein SE, Hopper K. Period prevalence and mortality rates associated with hypocholesterolaemia in dogs and cats: 1,375 cases. J Small Anim Pract 2020; 61:669-675. [PMID: 32767372 DOI: 10.1111/jsap.13204] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Revised: 05/09/2020] [Accepted: 06/25/2020] [Indexed: 12/26/2022]
Abstract
To determine the period prevalence of hypocholesterolaemia and the associated mortality rates in dogs and cats at a university teaching hospital. The secondary aim was to identify disease processes associated with hypocholesterolaemia. MATERIALS AND METHODS Medical records over a 5-year period were reviewed to determine the severity of hypocholesterolaemia and its associated mortality rate. Medical records of animals with moderate to severe hypocholesterolaemia (<2.59 mmol/L in dogs, <1.81 mmol/L in cats) were analysed further. Animals with hospital-acquired hypocholesterolaemia were identified. RESULTS Among 16,977 dogs and 3,788 cats that had at least one cholesterol measurement, the period prevalence of hypocholesterolaemia was 7.0% in dogs and 4.7% in cats. The mortality rate of hypocholesteraemic dogs and cats was 12% in both species which was significantly higher than that of animals with normal serum cholesterol. The degree of hypocholesterolaemia was significantly associated with mortality. Dogs, but not cats, with hospital-acquired hypocholesterolaemia had a higher mortality rate than those presenting with hypocholesterolaemia. Disease of hepatic, gastrointestinal and lymphoreticular systems were most commonly associated with hypocholesterolaemia, and infectious and neoplastic disease were the most commonly associated pathophysiologic processes in both species. Lymphoma was over-represented in dogs with neoplasia. CLINICAL SIGNIFICANCE Hypocholesterolaemia is not a frequent abnormality but was associated with mortality in this study and may be a negative prognostic indicator. It is not known if hypocholesterolaemia is simply a marker for disease severity, or if it is has active physiologic effects contributing to poor outcomes.

Abstract
OBJECTIVES The aim of this study was to describe the clinicopathologic findings and associated diseases found in a population of hypocholesterolemic cats referred to two tertiary care facilities. METHODS An electronic medical record search was performed at two veterinary university referral centers to identify cats with serum cholesterol values below the reference interval between January 2004 and 2016. Clinicopathologic data were reviewed for each case and cats were classified into specific disease categories based on clinical diagnosis. Median cholesterol values were compared between disease categories, as well as between survivors and non-survivors. RESULTS In total, 106 hypocholesterolemic cats were included. The median age of the cats was 6 years (range 0.24-18 years). The most common disease categories were gastrointestinal (25.9%), hepatobiliary (19.8%), hematologic (14.8%) and urogenital (14.8%). Though median serum cholesterol values did not differ significantly between survivors and non-survivors, cats with concurrent hypoalbuminemia were at higher risk (odds ratio 15.6, 95% confidence interval 5.2-46.6; P <0.0001) of not surviving to discharge than cats with normal serum albumin concentrations. CONCLUSIONS AND RELEVANCE Taken together, our data suggest that while the degree of hypocholesterolemia did not appear to influence survival rates, the concurrent presence of hypocholesterolemia and hypoalbuminemia was associated with a worse prognosis.
