Characterization of hypertriglyceridemia and response to treatment with insulin in horses, ponies, and donkeys: 44 cases (1995-2005).

The study examines the effects of insulin treatment on horses, ponies, and donkeys that suffer from hypertriglyceridemia, an excessive amount of triglycerides in their blood system. The researchers found that insulin treatments significantly reduced the triglycerides levels in affected animals, regardless of their age, sex, or other diseases.

Objective of the Research

• The researchers wanted to understand the disease signalment, clinical symptoms, and the response of horses, ponies, and donkeys with hypertriglyceridemia to insulin treatment. Hypertriglyceridemia refers to a condition where there are excessively high levels of triglycerides in the blood.

Methods Used in the Research

• The retrospective case series involved a total of 44 equids – 20 horses, 17 ponies, and 7 donkeys showing signs of hypertriglyceridemia.
• The subjects were categorized into subgroups based on their initial levels of triglycerides and whether they were treated with insulin. The groups were labeled as HT-I (those treated with insulin), HT-N (those not treated with insulin) and LIP-I (those with triglycerides levels above 500 mg/dL, and treated with insulin).
• The researchers both studied the number of pre-existing conditions and the age range of the equids while conducting the analysis.

Results of the Study

• The research showed that hypertriglyceridemia could affect equids of all ages and sexes, and it didn’t depend on whether they were pregnant or lactating.
• The majority of diseases found in hypertriglyceridemic equids included colitis and colic, and it affected a wide range of breeds like American Miniature Horses and Arabians or Arabian crossbreds.
• The post-treatment triglycerides concentration levels were not significantly different in the HT-N group; however, there was a substantial reduction in the HT-I and LIP-I groups after the insulin treatment.

Conclusion

• The study concluded that hypertriglyceridemia affects equids of all ages and sexes with various diseases. Furthermore, insulin treatment was found to be effective in reducing the triglycerides concentrations in affected equids.
