Diagnostic value of the neutrophil myeloperoxidase index in horses with systemic inflammation.

Abstract: The myeloperoxidase index (MPXI) was investigated as a diagnostic indicator of systemic inflammation in a retrospective study using data from 859 hospitalised horses. A reference interval of 8.5-10.4 for the MPXI was established. In horses with systemic inflammatory response syndrome (SIRS), the MPXI was significantly lower than in healthy horses, those with localised inflammation and those with sepsis. The MPXI in horses with sepsis was also significantly lower than in healthy animals and those with localised inflammation. Horses in the SIRS group with leucopenia, white blood cell (WBC) count within the reference interval (WRI) or leucocytosis had significantly lower MPXIs than healthy horses, those with localised inflammation and those with sepsis in the same WBC count subgroups. In horses with sepsis and WBC count WRI, the MPXI was significantly lower than in healthy horses or those with localised inflammation. MPXI is a useful complementary tool to identify horses with systemic inflammation, especially if they have WBC counts WRI.

The research paper focuses on studying the effectiveness of the myeloperoxidase index (MPXI) as a diagnostic marker for systemic inflammation in horses. It identified that horses with systemic inflammation, more so those with normal white blood cell count, presented lower MPXI, setting it as a useful tool in identifying such health issues.

Study Background

  • The research retrospectively analyzed data from 859 hospitalized horses to study the value of the MPXI as a marker for systemic inflammation.
  • The MPXI is a measure derived from white blood cells, particularly neutrophils, and is an indicator of their activation state.
  • The focus of the study was to establish the MPXI’s effectiveness in identifying horses suffering from a systemic inflammatory response syndrome (SIRS) or sepsis, both severe forms of inflammation that affect the whole body.

Findings

  • The researchers established a reference interval of 8.5-10.4 for the MPXI.
  • Horses battling SIRS were found to exhibit significantly lower MPXI than healthy horses, those with localized inflammation, and those with sepsis.
  • Similarly, horses with sepsis also displayed significantly lower MPXI than healthy horses and those with localized inflammation.
  • Upon further dissection of the data into subgroups based on white blood cell (WBC) count, it was inferred that even within each WBC subgroup (leucopenia: low WBC count, WRI: WBC count within the reference interval, or leucocytosis: high WBC count), horses with SIRS had considerably lower MPXI.
  • In septic horses with WBC count within the reference interval, the MPXI was still significantly lower compared to healthy horses or those with local inflammation.

Conclusion and Importance

  • The research concludes that the MPXI can be a valuable supplementing diagnostic tool for identifying systemic inflammation in horses, particularly useful when horses have a WBC count within the normal range.
  • This unique aspect is significant as systemic inflammation could potentially go unnoticed in cases where the horse has a normal WBC count, potentially leading to delayed treatment and poorer health outcomes.
  • Thus, monitoring the MPXI could provide an early warning sign of severe systemic inflammation, leading to timely intervention and treatment.
