Expression of interleukin-1β, interleukin-8, and interferon-γ in blood samples obtained from healthy and sick neonatal foals.
Abstract: To evaluate and compare the gene expression of interleukin(IL)-1β, IL-8, and interferon-γ during the first 72 hours after birth in healthy foals and during the first 72 hours after hospitalization in sick neonatal foals and investigate correlations of clinicopathologic variables with cytokine expressions in healthy and sick neonatal foals. Methods: 33 foals < 7 days old (10 healthy foals, 7 foals with sepsis, 6 foals with peripartum asphyxia syndrome, and 12 foals with other diseases [2 with failure of passive transfer of immunity only were not further evaluated]). Methods: A blood sample (15 mL) was collected from each foal immediately after birth or hospital admission (0 hours) and at 24 and 72 hours later. Clinicopathologic variables were evaluated, and cytokine gene expression in WBCs was measured with an absolute quantitative real-time reverse transcriptase PCR assay. Results: At all time points, gene expression of interferon-γ was low in all groups. No time-dependent changes in cytokine expressions were detected in healthy or sick foals. Foals with sepsis had significantly higher IL-1β gene expression than did healthy foals, foals with peripartum asphyxia syndrome, or foals with other diseases. At 0 hours, IL-1β expression was correlated with plasma fibrinogen concentration in healthy foals and with the neutrophil-to-lymphocyte ratio in foals with sepsis; IL-8 expression was correlated with monocyte count in foals with sepsis and with arterial pH, plasma fibrinogen concentration, and plasma lactate concentration in foals with peripartum asphyxia syndrome. Conclusions: Data have suggested that evaluation of IL-1β expression in sick neonatal foals could help identify those with sepsis.

This research looks into the gene expression of interleukin-1β, IL-8, and interferon-γ within the first 72 hours of birth in both healthy and sick newborn horses. It suggests that the evaluation of IL-1β expression in sick neonatal foals could help identify those with sepsis.
Objective of the Study
- The research was conducted to evaluate and compare the gene expression of interleukin-1β (IL-1β), IL-8, and interferon-γ during the first 72 hours after birth in both healthy and sick neonatal foals.
- The study also aimed to investigate possible correlations of clinicopathologic variables with cytokine expressions in these foals.
Methods Employed
- The study was conducted on 33 foals that were less than seven days old, including 10 healthy foals, 7 foals with sepsis, 6 foals with peripartum asphyxia syndrome, and 12 with other diseases.
- A 15mL blood sample was taken from each foal immediately after birth or hospital admission and again at 24 and 72 hours later.
- The clinicopathologic variables were evaluated, and cytokine gene expression in white blood cells (WBCs) was measured using an absolute quantitative real-time reverse transcriptase PCR assay.
Results of the Study
- Throughout all time points, the gene expression of interferon-γ was low in all groups, and no time-dependent changes in cytokine expressions were found in either healthy or sick foals.
- Foals with sepsis were found to have significantly higher IL-1β gene expression than healthy foals, foals with peripartum asphyxia syndrome, or foals with other diseases.
- The study also revealed correlations between IL-1β and other variables such as plasma fibrinogen concentration in healthy foals and the neutrophil-to-lymphocyte ratio in foals with sepsis. Correlations were also discovered between IL-8 expression and monocyte count in foals with sepsis, and arterial pH, plasma fibrinogen concentration, and plasma lactate concentration in foals with peripartum asphyxia syndrome.
Conclusions of the Study
- The data from this study suggested that evaluating IL-1β expression in sick neonatal foals could aid in identifying those with sepsis.
