Role of immature platelet fraction (IPF) in sepsis patients: A systematic review

Sepsis is extremely common amongst critically ill patients and requires early diagnosis. Hence, identifying a biomarker that could acknowledge sepsis at its prior stage is of vital significance. Immature platelets are a percentage of circulating platelets that contain RNA and is a newer parameter that is measured using automated hematology analyzers in diagnosing sepsis. This review article discusses 10 articles that reveal the role of immature platelet fraction in predicting the onset of sepsis and its relationship with mortality in sepsis. Literature search was done using PubMed, Scopus and Google Scholar and words like platelet indices and immature platelet fraction were typed in the search bar. The aim of this review article is to present a precise form of data that talk about immature platelet fraction (IPF) and its association with the severity and mortality of sepsis. Five out of 10 articles suggest that immature platelet fraction can predict the onset of sepsis and eight out of 10 articles suggest that increased IPF values are associated with high mortality.
