Sepsis is a life-threatening organ dysfunction triggered by an unregulated response of a host to infection. Sepsis is a reason for substantial mortality and morbidity among intensive care unit (ICU) patients. 1 Therefore, the aim of our study is to compare the safety and efficacy of metformin and lactoferrin in ICU patients with sepsis.

Sepsis is a life-threatening organ dysfunction triggered by an unregulated response of a host to infection. Sepsis is a reason for substantial mortality and morbidity among intensive care unit (ICU) patients. 1 The pathophysiology of sepsis has changed spectacularly over the last several decades. Significant comprehension into the components of the inflammatory response has been achieved. Inflammation contributes to endothelial injury and initiates coagulation pathways.2 The inflammatory reaction is mediated by the release of cytokines (tumor necrosis factor-alpha, interleukins, and prostaglandins) from neutrophils and macrophages. The cytokines trigger the extrinsic coagulation cascade and inhibit fibrinolysis. These overlapping processes end with organ dysfunction.3 The Sequential Organ Failure Assessment or SOFA score was developed to assess the acute morbidity of critical illness at a population level and has been extensively validated as a tool for this purpose across a range of healthcare settings and environments.4 Metformin is oral anti-diabetic agent that has positive effects such as antioxidant and anti-inflammatory properties which are considered potentially beneficial properties for management of septic patients. Previous studies showed that preadmission metformin use may reduce mortality in adult patients with sepsis and diabetes mellitus. Therefore, our study aims to test the potential efficacy of metformin in all subsets of patient with sepsis.5,6 Lactoferrin is a cationic glycoprotein and associated with many activities including the relevant anti-inflammatory one, especially associated to the downregulation of pro-inflammatory cytokines besides its anti-microbial and immunomodulatory effect.7 A previous study suggested that lactoferrin supplementation to enteral feeds with or without probiotics decreases late-onset sepsis in preterm infants without adverse effects and this encourage us to test its role in adult patients with sepsis.8 Therefore, the aim of our study is to compare the safety and efficacy of metformin and lactoferrin in ICU patients with sepsis.
