Insights

Pediatric patients undergoing allogeneic hematopoietic stem cell transplant (allo-HSCT) have high PICU mortality. Aggressive cardiac support and low neutrophil counts post-transplant predict worse outcomes.

Area of Science:

  • Pediatric Hematology/Oncology
  • Bone Marrow Transplantation
  • Pediatric Critical Care Medicine

Background:

  • Allogeneic hematopoietic stem cell transplantation (allo-HSCT) can lead to life-threatening complications.
  • A significant number of pediatric patients require Pediatric Intensive Care Unit (PICU) admission following allo-HSCT.

Purpose of the Study:

  • To evaluate the incidence and outcomes of PICU admissions after pediatric allo-HSCT.
  • To identify factors influencing survival in children admitted to the PICU post-allo-HSCT.

Main Methods:

  • Retrospective chart review of 668 children undergoing their first allo-HSCT between 2005-2017.
  • Focus on PICU admissions within one year post-transplant.
  • Analysis of factors including mechanical ventilation (MV), cardiac support, and absolute neutrophil count (ANC).

Main Results:

  • 8.7% of patients (58/668) required 64 PICU admissions.
  • Mortality rate in the PICU was high, with 58.6% of admitted patients dying.
  • Patients who died were more likely to require MV (91.2%), aggressive cardiac support (50%), and had lower ANC (P=.004) on the last PICU day.
  • Five patients treated with non-invasive ventilation (NIV) survived >6 months post-discharge.

Conclusions:

  • Pediatric PICU admissions after allo-HSCT are associated with high mortality.
  • Intensity of cardiac support and ANC on the last PICU day are independent predictors of survival.
  • While MV is linked to decreased survival, early NIV implementation may be beneficial.

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...

Role of Hematopoietic Growth Factors

Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.
Thrombopoietin (TPO), mainly released by the liver,...

Factors Affecting Erythropoiesis01:24

Factors Affecting Erythropoiesis

The cardiovascular system regulates the number of erythrocytes in the bloodstream to ensure optimal oxygen transport. It also prevents over-proliferation of these cells, which helps to maintain blood viscosity and flow rate.
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
EPO then...

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Multipotency of Hematopoietic Stem Cells01:19

Multipotency of Hematopoietic Stem Cells

The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

Stem Cell Therapy for Tissue Regeneration01:21

Stem Cell Therapy for Tissue Regeneration

Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.
