Increased plasma fructosamine concentrations in laminitic horses.
Abstract: The use of plasma fructosamine concentration ([fructosamine]) as a marker of abnormal glucose homeostasis in laminitic horses has not been investigated. Objective: Plasma fructosamine concentration may be higher amongst laminitic horses than normal horses; this might relate to underlying insulin resistance. Objective: 1) To compare [fructosamine] between laminitic and normal horses. 2) To investigate associations between [fructosamine] at presentation in laminitic horses with a) single sample markers of insulin resistance and b) outcome. Methods: Plasma fructosamine concentration, fasting serum insulin concentration (insulin) and fasting plasma glucose concentration (glucose) were measured in 30 horses that presented with laminitis. Clinical details and follow-up data were recorded. Plasma fructosamine concentration was also measured in 19 nonlaminitic control horses. Results: Laminitic horses had significantly higher mean [fructosamine] than normal horses (P<0.001). Thirteen of 30 laminitic horses had fasting hyperinsulinaemia, 2/30 had fasting hyperglycaemia. Statistically significant univariable correlations were identified between [fructosamine] and [glucose], [insulin] and the proxies RISQI and MIRG. Trends for association between [fructosamine] and negative outcome did not reach statistical significance. Conclusions: Increased mean [fructosamine] in laminitic horses may represent abnormal glycaemic control and [fructosamine] may become a clinically useful marker.

The research article investigates plasma fructosamine concentrations in horses with laminitis, a painful foot condition, and its potential as an indicator for abnormal glucose control. The study reveals that horses with laminitis have higher fructosamine concentrations than healthy horses, suggesting it could become a useful clinical marker.
Research Objectives
The research had two main objectives:
- To compare the concentration of plasma fructosamine between healthy horses and those suffering from laminitis.
- To investigate any possible relationships between the fructosamine levels in laminitic horses at the time of presentation and a) single sample markers of insulin resistance, and b) the eventual outcome or prognosis of the condition.
Methodology
The methods for this research were specifically detailed:
- Plasma fructosamine concentration, fasting serum insulin concentration, and fasting plasma glucose concentration were measured in 30 horses that were presented with laminitis.
- For comparison, the plasma fructosamine concentration was also measured in 19 horses that did not have laminitis (serving as control subjects).
- Additionally, the clinical details and follow-up data for each horse were recorded for further analysis.
Results
The results of the research showed:
- The mean plasma fructosamine concentration was significantly higher in the laminitic horses compared to the healthy horses.
- Out of 30 laminitic horses, 13 had fasting hyperinsulinaemia (an excess of insulin in the blood) and two had fasting hyperglycaemia (an excess of glucose in the blood).
- There were statistically significant correlations between the fructosamine levels and glucose levels, insulin levels, and the proxies for insulin resistance in the body of the horses (RISQI and MIRG).
Conclusion
Though any association between fructosamine levels and negative clinical outcomes wasn’t statistically significant, the research concludes that the increased mean plasma fructosamine concentration in laminitic horses may be indicative of abnormal glucose control. This could, in turn, suggest the potential application of plasma fructosamine as a clinically helpful marker for diagnosing and managing horses with laminitis.
