Lecture: Haemocytometry to differentiate infectious causes of infectious diseases and management of COVID-19

Antimicrobial resistance (AMR) is one of the biggest threats to global health and is fuelled, among others, by the misuse and overuse of antimicrobial drugs. Diagnostics are a key tool to address the spread of AMR: a simple test flagging the presence or absence of bacterial infections can dramatically cut antibiotic overuse. Complete blood count (CBC) with leukocyte differentiation is currently the most used technique to screen for the presence of infection. New generation haematology analysers have improved capacity to detect phenotypical changes in leukocyte sub-sets, leading to a more comprehensive panel of blood cell makers and thereby also to the diagnostic software algorithm tested in this manuscript – the Infection Manager System (IMS) – designed to differentiate bacterial from viral infections. A diagnostic accuracy study was thereafter performed in Burkina Faso to test the accuracy of the IMS, alongside standard malaria diagnostics, to detect bacteraemia in a malaria endemic setting, and compare its accuracy to CRP and PCT. IMS showed a high negative predictive value to detect bacterial infections and may be a promising tool to assist clinicians in their decision to prescribe or withhold antibiotics in patients with AFI.
