To provide an appraisal of the evolving paradigms in the pathophysiology of sepsis, propose the evolution of a new phenotype of critically ill patients, its potential underlying mechanism, and its implications for the future of sepsis management and research. Literature search using PubMed, MEDLINE, EMBASE, and Google Scholar. Sepsis remains one of the most debilitating and expensive illnesses, and its incidence is not declining. What is changing is our definition(s), its clinical course, and how we manage the septic patient. Once thought to be predominantly a syndrome of over exuberant inflammation, sepsis is now recognized as a syndrome of aberrant host protective immunity. Earlier recognition and compliance with treatment bundles has fortunately led to a decline in multiple organ failure and in-hospital mortality. Unfortunately, more and more sepsis patients, especially the aged, are suffering chronic critical illness (CCI), rarely fully recover and often experience an indolent death. Patients with CCI often exhibit ‘a persistent inflammatory-immunosuppressive and catabolic syndrome’ or PICS, and it is proposed here that PICS contributes to many of these adverse clinical outcomes. The underlying cause of PICS is currently unknown, but there is increasing evidence that altered myelopoiesis, reduced effector T-cell function and expansion of immature myeloid-derived suppressor cells are all contributory. Although newer therapeutic interventions are targeting the inflammatory, the immunosuppressive, and the protein catabolic responses individually, successful treatment of the septic patient with CCI and PICS may require a more complementary approach.
