Highlights

• The highly heterogeneous nature of sepsis arises from various factors, including diverse causative pathogens and individual patient characteristics such as age, sex, and comorbidities. This variability complicates treatment and suggests that a one-size-fits-all approach may be ineffective.

• Recent studies have shown that sepsis patients can be stratified into more homogeneous subgroups, based on clinical characteristics (subphenotypes) or underlying pathophysiological mechanisms (endotypes).

• Identification of subgroups among sepsis patients may enhance the understanding of patient outcomes and guide personalized medicine approaches. Nonetheless, challenges remain in establishing standardized criteria for classification and ensuring that diagnostic methods are practical for clinical use.

Abstract

According to the latest definition, sepsis is characterized by life-threatening organ dysfunction caused by a dysregulated host response to an infection. However, this definition fails to grasp the heterogeneous nature and the underlying dynamic pathophysiology of the syndrome. In response to this heterogeneity, efforts have been made to stratify sepsis patients into subtypes, either based on their clinical presentation or pathophysiological characteristics. Subtyping introduces the possibility of the implementation of personalized medicine, whereby each patient receives treatment tailored to their individual disease manifestation. This review explores the currently known subtypes, categorized by subphenotypes and endotypes, as well as the treatments that have been researched thus far in the context of sepsis subtypes and personalized medicine.
