Insights

Elevated neutrophil to lymphocyte and platelet ratios (NLPR) in septic children indicate a higher risk of mortality. This simple blood test shows prognostic potential comparable to established scores for predicting outcomes in pediatric sepsis.

Area of Science:

  • Pediatric critical care medicine
  • Immunology
  • Hematology

Background:

  • Sepsis pathogenesis involves critical immune cell responses.
  • Evaluating immune cell ratios offers prognostic insights in pediatric sepsis.

Purpose of the Study:

  • To assess the prognostic significance of various peripheral blood immune cell ratios in children with sepsis.
  • To determine the predictive value of these ratios for mortality in pediatric sepsis patients.

Main Methods:

  • Retrospective analysis of clinical data from 230 septic children.
  • Calculation of neutrophil to lymphocyte ratio (NLR), derived NLR (dNLR), neutrophil to lymphocyte and platelet ratio (NLPR), monocyte to lymphocyte ratio (MLR), and platelet to lymphocyte ratio (PLR).
  • Statistical analysis using LOWESS, ROC analysis, and K-M analysis to correlate ratios with mortality.

Main Results:

  • All tested immune cell ratios, except PLR, were higher in non-survivors.
  • NLPR, NLR, MLR, and dNLR showed a linear association with in-hospital mortality.
  • NLPR demonstrated the highest AUC (0.748), comparable to the Pediatric Critical Illness Score (PCIS).
  • Elevated MLR, NLR, dNLR, and NLPR were linked to increased 30-day mortality.

Conclusions:

  • The NLPR is a potential prognostic indicator in pediatric sepsis.
  • NLPR's predictive capacity is comparable to the established PCIS.
  • Immune cell ratios offer valuable prognostic information for septic children.

Differentiation of Common Myeloid Progenitor Cells

Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Disorders of Leukocytes01:27

Disorders of Leukocytes

Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

Inflammatory Response II: Inflammatory Exudate and Tissue Repair01:24

Inflammatory Response II: Inflammatory Exudate and Tissue Repair

The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...
