Incidence and risk factors for recurrence of endocrinopathic laminitis in horses.


ABSTRACT:

Background

Endocrinopathic laminitis is common in horses and ponies, but the recurrence rate of the disease is poorly defined.

Objectives

To determine the incidence of, and risk factors for, the recurrence of endocrinopathic laminitis.

Animals

Privately owned horses and ponies with acute laminitis (n?=?317, of which 276 cases with endocrinopathic laminitis were followed up to study completion).

Methods

This prospective cohort study collected data on veterinary-diagnosed cases of acute laminitis for 2 years. Each case was classified on acceptance to the study as endocrinopathic or non-endocrinopathic using data collected in a questionnaire completed by the animal's veterinarian. Follow-up data were collected at regular intervals to determine whether the laminitis recurred in the 2-year period after diagnosis.

Results

The recurrence rate for endocrinopathic laminitis was 34.1%. The risk of recurrence during the 2-year study period increased with basal, fasted serum insulin concentration (P???.05), with the probability of recurrence increasing markedly as the insulin concentration increased beyond the normal range (0-20 ?IU/mL) to over the threshold for normal (up to approximately 45 ?IU/mL). Being previously diagnosed with laminitis (before the study; P?=?.05) was also a risk factor for recurrent laminitis. Cases with a higher Obel grade of laminitis were likely (P?=?.05) to recur sooner.

Conclusions and clinical importance

Knowing that hyperinsulinemia and being previously diagnosed with laminitis are significant risk factors for recurrence will enable clinicians to proactively address these factors, thereby potentially reducing the risk of recurrence of laminitis.
