  • Test Sooner, Act Faster – Enhance Sepsis Care with Poclight Diagnostics

    1. The Global Burden of Sepsis

     

    Sepsis is a life-threatening condition caused by the body’s extreme response to infection.

    From data published in 2020, globally, over 49 million people are affected each year, with approximately 11 million deaths, representing 20% of all global deaths (Global, regional, and national sepsis incidence and mortality, 1990-2017: analysis for the Global Burden of Disease Study. Lancet. 2020 Jan 18).

    Sepsis affects people globally, but incidence and mortality are highest in lower-middle-income countries (LMICs). In high-income countries, the average hospital cost per sepsis patient exceeds US$32,000.

     

    Understanding the Risk

    Anyone can develop an infection that leads to sepsis, but certain factors increase susceptibility. Older adults, infants (40% of all cases), pregnant women, and patients with pre-existing conditions—such as chronic kidney disease, liver disease, cancer, or heart failure—face higher risk.

    Socioeconomic factors, access to healthcare, and living conditions also play a role, particularly in low- and middle-income countries where infections may be more prevalent and timely medical care is harder to access.

    ● High-risk populations: older adults, infants (half of all cases), pregnant women

    ● Pre-existing conditions: chronic kidney disease, liver disease, cancer, heart failure

    ● Socioeconomic & environmental factors: limited healthcare access, overcrowded living, poor sanitation

     

    2. The Role of Biomarkers in Sepsis Diagnosis

     

    Inflammatory biomarkers are measurable indicators of the body’s immune response to infection. In sepsis, key inflammatory biomarkers may include the following:

    sepsis biomarkers

    Sepsis, septic shock, and sepsis-associated encephalopathy biomarkers. (Barichello, T., Generoso, J.S., Singer, M. et al. Biomarkers for sepsis: more than just fever and leukocytosis—a narrative review. Crit Care 26, 14 (2022))

    Clinical benefits of monitoring these biomarkers:

    ● Early detection of sepsis and assessment of severity

    ● Informed decisions on initiating, adjusting, or discontinuing antimicrobial therapy

    ● Support antimicrobial stewardship (AMS): Reduced unnecessary antibiotic exposure without increasing mortality

    ● Real-time monitoring of treatment effectiveness alongside pathogen identification and antibiotic susceptibility testing

     

    3. Poclight’s Solution: Speed, Precision, and Accessibility

     

    Poclight’s C5000 dry chemiluminescence immunoassay system offers a reliable approach to testing a panel of inflammatory and sepsis-related biomarkers, including PCT, CRP, IL-6, and HBP.

    1.  Introduction

    Inflammation is a key response of the body to infection, tissue injury, or other stressors. Early detection is critical because timely recognition can guide treatment decisions and improve patient outcomes.

    Interleukin-6 (IL-6) is a pro-inflammatory cytokine released by immune cells in response to infection or tissue damage. Its levels rise within 2 hours, significantly earlier than PCT (>2 hours) and CRP (>6 hours). This rapid increase makes IL-6 a valuable marker for early detection of systemic inflammation across a variety of clinical scenarios.

    2.  Practical Value of IL-6 Testing

    In clinical practice, IL-6 is used across multiple scenarios:

    ● Hospitals and clinics: Early detection of sepsis and other acute inflammatory conditions.

    ● Laboratories: Rapid and reliable measurement of IL-6 supports timely reporting and monitoring.

    ● Specialized departments: Post-surgical care, transplant units, pulmonary wards, and oncology can use IL-6 to assess infection, tissue injury, immune response, or tumor progression.
