mSEP: Testing of Physiological and Immune-metabolic Blood Markers for Maternal Sepsis

Overview

A prospective observational cohort study investigating physiological parameters vs biological markers of whole blood in septic and non-septic pregnant woman to predict systemic immune health

The altered physiology of pregnancy makes the signs and symptoms of sepsis less distinctive in the pregnant population. This can lead to both over treatment (with antibiotics) and late identification of sepsis. The progression of sepsis can be rapid in this population, resulting in severe morbidity and mortality. The mortality associated with sepsis in the general population is over 10%, while septic shock can increase this figure up to 30%. A study looking at maternal mortality due to sepsis recognised that the time from the onset of infection to death was less than 24 hours in 50% of patients. A review of the literature shows that half of the fatal cases of maternal sepsis could have been prevented with early detection of sepsis. The unmet need is therefore a diagnostic bedside tool that can be performed on women identified as high risk via physiological parameters. The tool needs to be quick and easy to use whilst accurate at diagnosing sepsis. Study Objectives To evaluate the effectiveness of physiological parameters in predicting maternal sepsis. To evaluate the effectiveness of alternative biomarkers in diagnosing maternal sepsis including a genomic sepsis-test. Investigation of the systemic immune health of women undergoing an uncomplicated pregnancy and labour.
