Combating Multidrug-resistant Gram-negative Bacteria in Africa Through Diagnostic and Antimicrobial Stewardship
Sponsor: Universität des Saarlandes
Summary
Antimicrobial resistance (AMR) is a major threat to public health and the well-being of humans, with high mortality rates of infections caused by MDR GNB. Sub-Saharan Africa (SSA) suffers from a high burden of AMR, but access to adequate microbiological diagnostics for pathogen identification and resistance testing as well as to novel antibiotics that are effective against MDR GNB are scarce. Studies from high-income countries show improved survival of patients with such infections, if novel antibiotics against these pathogens are employed in a targeted manner. However, data from low- and middle-income countries (LMICs) is limited. The purpose of this study is to obtain an accurate picture of the epidemiology of MDR GNB in hospitals in Côte d'Ivoire, Guinea-Bissau and Nigeria, followed by the development and implementation of an evidence-based AMS algorithm, which is coupled to access to antibiotics (i.e. meropenem, ceftazidime-avibactam, cefiderocol and ceftazidime-avibactam + aztreonam) with proven activity against MDR GNB. Taken together, the overall goal is to improve the management of severe infections due to MDR GNB in SSA.

Interventions
Treatment according to AMR algorithm
In this study stage, a diagnosis-treatment algorithm that will have been developed based on data collected during study stage 1, will be employed as the intervention to guide the choice of antibiotics active against MDR GNB BSIs. Coupled to the algorithm, a set of specific antibiotics will be made available in the different study settings for treatment of patients with infections due to MDR GNB, for which no equally effective antibiotics are routinely available in the study countries. Previously held discussions with the regulatory agencies in the study countries will feed into the development of the algorithm. The novel treatment options include antibiotics which retain activity in MDR GNB with specific resistance profiles such as ESBL-producing isolates and those with carbapenem resistance. If an antibiotic is not yet licensed in the study country, its use will follow the European Medicines Agency's (EMA) licensing recommendations. The following drugs will be used whenever the causa
