To determine if ICU patients should be routinely supplemented with thiamine as part of their standard treatment by assessing:
- A, reference range for thiamine in the blood of healthy adult dogs and cats;
- B, prevalence of thiamine deficiency and response to subcutaneous repletion in critically ill dogs and cats (including Oncology patients).
What is thiamine?
Thiamine, also known as vitamin B1, is a nutrient that is important for both metabolism and proper functioning of the nervous system. Thiamine, a water-soluble vitamin, cannot be produced in the body and is not stored in the body’s tissues, so it must regularly be taken in through the diet.
What are the dietary sources of thiamine?
Thiamine in commercial pet foods can come from whole grains (e.g. wheat germ), legumes, yeast, organ meats (e.g. liver, heart, and kidneys), or from supplements (e.g. thiamine mononitrate or thiamine hydrochloride).
When can thiamine deficiency occur?
During critical illness, many dogs and cats often have reduced appetites and are not able to consume enough energy and nutrients to meet their needs. This means they are also not consuming sufficient thiamine and are at risk of deficiency.
Cats are more susceptible to thiamine deficiency than dogs, as they require 4-5 times more thiamine in their diets.
