Increased mean platelet volume in septicaemia

Area of Science:

• Hematology
• Infectious Diseases
• Clinical Pathology

Background:

• Septicemia is a severe, life-threatening condition.
• Early detection of septicemia is crucial for effective treatment.
• Platelet parameters are increasingly recognized as potential biomarkers in infections.

Purpose of the Study:

• To investigate the diagnostic utility of mean platelet volume (MPV) in differentiating localized bacterial infections from septicemia.
• To assess the correlation between MPV and treatment response in bacterial infections.

Main Methods:

• Prospective study comparing MPV in patients with proven septicemia versus localized bacterial infection.
• MPV was measured using a Coulter counter model S plus.
• MPV levels were monitored during antibiotic treatment.

Main Results:

• 13 of 25 septicemia patients had increased MPV; none of 25 localized infection patients did.
• Increased MPV was observed irrespective of platelet count or specific microorganism.
• Patients responding to antibiotics normalized MPV within a week.
• Non-responders and non-survivors showed persistently elevated or increasing MPV levels.

Conclusions:

• Increased MPV may serve as an early indicator of invasive bacterial infection (septicemia).
• Persistent elevation of MPV suggests inadequate treatment response.
• MPV monitoring can aid in assessing treatment efficacy and patient prognosis in bacterial infections.
