Abstract:
Sepsis, defined as life-threatening organ dysfunction caused by a dysregulated host response to an infection, remains a major challenge for clinicians and trialists. Despite decades of research and multiple randomized clinical trials, a specific therapeutic for sepsis is not available. The evaluation of therapeutics targeting components of host response anomalies in patients with sepsis has been complicated by the inability to identify those in this very heterogeneous population who are more likely to benefit from a specific intervention. Additionally, multiple and diverse host response aberrations often co-exist in sepsis, and knowledge of which dysregulated biological organ system or pathway drives sepsis-induced pathology in an individual patient is limited, further complicating the development of effective therapies. Here, we discuss the drawbacks of previous attempts to develop sepsis therapeutics and delineate a future wherein interventions will be based on the host response profile of a patient.
Insights
Sepsis therapeutics face challenges due to patient heterogeneity and complex host responses. Future treatments may involve personalized interventions based on individual patient profiles for better outcomes.
Area of Science:
- Critical care medicine
- Immunology
- Translational research
Background:
- Sepsis, a life-threatening organ dysfunction from infection, lacks specific treatments despite extensive research.
- Developing effective sepsis therapies is hindered by patient heterogeneity and complex, co-existing host response abnormalities.
- Identifying patients likely to benefit from specific interventions remains a significant obstacle in sepsis clinical trials.
Purpose of the Study:
- To review the limitations of past sepsis therapeutic development strategies.
- To propose a future direction for sepsis treatment based on host response profiling.
Main Methods:
- Discussion of challenges in previous sepsis therapeutic trials.
- Analysis of host response heterogeneity in sepsis patients.
- Conceptual framework for personalized sepsis interventions.
Main Results:
- Previous therapeutic approaches have been hampered by the inability to stratify patients effectively.
- The diverse and overlapping nature of host responses in sepsis complicates treatment development.
- A significant knowledge gap exists regarding the specific drivers of pathology in individual sepsis cases.
Conclusions:
- Personalized medicine approaches, guided by host response profiles, offer a promising future for sepsis treatment.
- Stratifying sepsis patients based on their unique biological signatures is crucial for developing targeted and effective therapies.
- Moving beyond one-size-fits-all treatments is essential for advancing sepsis care and improving patient survival.
