Erythropoietin in the Management of Premature Infant Anemia

December 24, 2023by Dr. S. F. Czar0

Patient Profile:

  • Patient: Baby Emma
  • Gestational Age at Birth: 29 weeks
  • Birth Weight: 1,100 grams
  • Neonatal History: Emma was born prematurely due to preterm labor. She required mechanical ventilation for respiratory distress syndrome (RDS) and received surfactant therapy. She also had a patent ductus arteriosus (PDA) that was medically managed.

Clinical Presentation:

At 2 weeks of age, Baby Emma is showing signs of anemia, including pallor and increased work of breathing. Hematocrit testing reveals a significant drop in her hemoglobin levels.


Based on her clinical presentation and laboratory results, Baby Emma is diagnosed with anemia of prematurity, a common condition in premature infants due to reduced erythropoiesis and relatively higher blood volume.

Treatment Plan:

  • Monitoring: Baby Emma’s hematocrit levels are monitored closely, and it is observed that her anemia is not improving spontaneously despite appropriate nutritional support and red blood cell transfusions.
  • Erythropoietin (EPO) Evaluation: Given the severity of her anemia and her continued need for respiratory support, EPO therapy is considered to stimulate red blood cell production.
    • Emma undergoes a thorough evaluation, including measurement of her serum EPO levels, which are found to be low for her postnatal age.
  • EPO Therapy: Based on the evaluation results and clinical judgment, Emma’s healthcare team decides to initiate EPO therapy. She receives subcutaneous injections of synthetic EPO to stimulate erythropoiesis.
    • The dosage and frequency of EPO administration are determined based on her weight and hematocrit levels.
  • Iron Supplementation: Iron studies are conducted to assess her iron status. Emma is prescribed oral iron supplementation to support red blood cell production.
  • Regular Monitoring: Emma’s hematocrit levels and general well-being are closely monitored during EPO therapy. Adjustments in EPO dosage and iron supplementation are made as needed to maintain her hemoglobin levels within the target range.


Over the next several weeks, Baby Emma’s hematocrit levels gradually improve with EPO therapy and iron supplementation. She becomes less pallor, and her work of breathing diminishes, indicating improved oxygen-carrying capacity. Her respiratory support requirements also decrease.


This case study highlights the essential role of Erythropoietin (EPO) in managing anemia of prematurity in a premature infant like Baby Emma. Her presentation with anemia, despite appropriate supportive care and red blood cell transfusions, underscores the challenges of anemia in premature infants due to their limited capacity for erythropoiesis.

EPO therapy, alongside iron supplementation, represents a crucial part of Emma’s comprehensive treatment plan. The goal is to stimulate erythropoiesis and correct her anemia, ultimately improving her oxygen-carrying capacity and supporting her overall well-being during her early days of life.

The careful monitoring of Emma’s hematocrit levels and the individualized approach to EPO therapy and iron supplementation are critical in ensuring her optimal response to treatment. This case demonstrates how early intervention and a thorough understanding of the hormonal considerations in premature infants can significantly impact their health and development during the vulnerable neonatal period.
