Hypertriglyceridaemia in Miniature Schnauzers and pancreatitis
6-year-old Miniature Schnauzer recovered from his second episode of pancreatitis. Hypothyroidism, hyperadrenocorticism and diabetes have been ruled out. After a 12-hour fast, with no signs of pancreatitis:
| Parameter | Result | Reference |
|---|---|---|
| Triglycerides | 650 mg/dL | 25–115 |
| Cholesterol | 280 mg/dL | 130–300 |
| Glucose | 98 mg/dL | 70–120 |
What is the first-line measure to reduce the risk of further episodes?
chevron_right Show answer and explanation
A. Atorvastatin as initial treatment
Statins act mainly on cholesterol and have little effect on triglycerides. In any case, no drug replaces diet as the first step.
B. None: the hypertriglyceridaemia is a consequence of the pancreatitis and will resolve on its own
Pancreatitis can raise lipids transiently, but here the dog is fasted and has no active pancreatitis. Primary hypertriglyceridaemia in Schnauzers persists and is associated with an increased risk of pancreatitis.
C. A lifelong low-fat diet, with no fatty treats or table scraps, and recheck fasting triglycerides after 6–8 weeks
Correct. Fat restriction is the first-line treatment for primary hypertriglyceridaemia. If triglycerides remain markedly raised, omega-3 fatty acids from fish oil or a fibrate can be added.
D. Empirical levothyroxine, because hypothyroidism is the most common cause of hyperlipidaemia
Hypothyroidism is indeed a common cause of secondary hyperlipidaemia, but it has already been ruled out. Giving levothyroxine without a diagnosis can cause iatrogenic thyrotoxicosis.
lightbulb Key takeaway
In any dog with recurrent pancreatitis, measure fasting triglycerides once recovered. Primary hypertriglyceridaemia is common in Miniature Schnauzers: rule out secondary causes and start with a strict low-fat diet.
