Sepsis is a life-threatening infection which, due to a dysregulated host response to infection, is responsible for more than 11 million deaths annually, a large percentage of which occur in sub-Saharan Africa (sSA). Emerging research shows promising benefits in treating sepsis patients with metabolic resuscitation using combinations of hydrocortisone, intravenous (IV) ascorbic acid (vitamin C) and IV thiamine (vitamin B1), alone or in combination. Studies are currently underway in the USA, Europe, Asia, and South America to understand whether combinations of these medicines or the medicines individually can improve outcomes for patients with sepsis. Although none of these studies are being conducted in sSA, the medicines comprising these metabolic 'bundles' are inexpensive, readily available and relatively safe to administer. It is critical that similar studies are conducted in sSA to evaluate whether or not these inexpensive medicines (or a combination of them) are efficacious for improved survival among patients with sepsis. If these studies prove that these medicines can improve survival from sepsis, there is a large potential to save many lives. Through the Preparation for Randomised Evaluation of a VItamin C bundle for Sepsis Treatment in Africa (REVISTA-Prep) studies, the investigators intend to conduct preliminary research in Uganda to help define parameters for a future RCT aimed at identifying the optimal vitamin C and vitamin B1 combination for improving survival from sepsis among adults in sSA, where resources are constrained, intensive care units are rare and issues like poverty, malnutrition and HIV are common. The study described in this protocol (i.e., REVISTA-DOSE) aims to establish the optimal vitamin C dosing strategy for the future REVISTA-RCT (assessing the efficacy of variations of a treatment bundle comprising vitamin C/B1 and/or hydrocortisone for reducing mortality among adult patients with sepsis in Africa).
