ABSTRACT: Mortality, morbidity, early recognition, and treatment of sepsis remain a diagnostic dilemma for clinicians, in addition, the timely diagnosis of sepsis represents an ongoing clinical challenge. This review looks at the challenges of early recognition, the scope of the problem, the immunologic basis of the sepsis cascade, new frontiers related to interventions, and the role of antibiotics in an era of antimicrobial resistance. In Figure 1, once a patient is on the slippery slope of sepsis, the ability to reverse the momentum is challenging; hoping antibiotics, fluid resuscitation, vasopressors may buy time for the immunologic cascade to equilibrate to its homeostatic balance. While the development of septic shock is much more complex than pathogen proliferation, our understanding of the pathogenesis and ability to therapeutically intervene is in its infancy. Patients with sepsis frequently present for urgent medical care with undifferentiated infection and nonspecific symptoms. As 80% of patients with sepsis are initially treated in an Emergency Department, the burden of early recognition and intervention falls squarely on the shoulders of Emergency Department Clinicians. [1] This is an entity that occurs in all age groups, without regard to race, geography, or health status. Survival and mortality related to this clinical entity are poorly understood. Our understanding of sepsis needs to expand beyond the downstream effects and collateral damage of multiorgan dysfunction and failure. Immunologically, the antigenic triggers, be it invasive infection, severe injury, and systemic inflammation without concomitant infection, elicit similar pattern recognition receptors and innate host responses. If you are lucky enough to have survived an acute episode of sepsis, patients with sepsis often develop new adverse sequelae after treatment, a concept called persistent critical illness or post sepsis syndrome, characterized by long-term disability, and worsening chronic health conditions requiring re-hospitalization.
