Anemia is a condition characterized by a decrease in the number of red blood cells or a deficiency in hemoglobin, which can lead to fatigue, weakness, and other complications. In recent years, cord blood, a rich source of stem cells, has emerged as a potential treatment for anemia.

This article explores the fascinating connection between cord blood and anemia, highlighting the advancements made through clinical trials and the potential it holds for those affected by various types of anemia.

What Is Anemia?

Anemia is a common blood disorder that affects millions worldwide. It occurs when the body lacks sufficient healthy red blood cells or hemoglobin, impairing the delivery of oxygen throughout the body. This can result from various factors, including nutritional deficiencies, chronic diseases, or genetic conditions [*].

What Is Cord Blood?

Cord blood is the blood collected from the umbilical cord and placenta following childbirth. It is a valuable source of hematopoietic stem cells, which have the remarkable ability to develop into various blood cell types, including red blood cells. These stem cells can be stored in public or private banks for potential future use [*].

How Can Cord Blood Help with Anemia?

The stem cells found in cord blood offer a potential solution for treating anemia. When infused into a patient's bloodstream, these cells can replenish the supply of healthy red blood cells and hemoglobin, helping to restore normal oxygen-carrying capacity and alleviate the symptoms associated with anemia.

Types of Anemia That Can Be Treated with Cord Blood

While ongoing research is shedding light on various types of anemia that may benefit from cord blood treatments, current focus areas include:

Sickle Cell Anemia

A group of inherited disorders known as sickle cell disease. Healthy red blood cells, which carry oxygen to all parts of the body, are round in shape and flexible and move easily through blood vessels. In sickle cell anemia, some of the red blood cells are shaped like sickles or crescent moons. These sickle cells also become rigid and sticky, and can slow or block blood flow through the body.

While there is no cure for most people with sickle cell anemia, treatments can relieve pain and help prevent complications associated with the disease [*].

Aplastic Anemia

A rare yet serious condition that occurs when your body stops producing enough new blood cells. Aplastic anemia can occur at any age and can appear suddenly or show up slowly and get worse over time. Cases may be mild or severe. This condition leaves one fatigued and more prone to infections and uncontrolled bleeding. Treatment could include medications, blood transfusions, or a stem cell transplant [*].

Diamond-Blackfan Anemia

A very rare blood disorder that affects red blood cell production in the bone marrow. It is a genetic disorder that’s symptoms can range from mild to serious depending on genetic changes.

Diamond-Blackfan anemia can predispose one to certain types of cancer as they age. Allogeneic stem cell transplantations are the only known cure for Diamond-Blackfan anemia [*].

Fanconi Anemia

An uncommon and severe hereditary blood disorder that leads to bone marrow failure, resulting in insufficient production of new blood cells necessary for the body's proper functioning. It falls into the aplastic anemia category. Additionally, this condition can cause the bone marrow to produce defective blood cells, which may lead to severe health issues, including leukemia, a form of blood cancer.

Despite being primarily a blood disorder, Fanconi anemia can impact various other organs, tissues, and systems throughout the body. Children who inherit this condition are at an elevated risk of experiencing birth defects, developing specific cancers, and encountering other severe health complications [*]. The first successful cord blood stem cell transplant involved treating Fanconi anemia.

Beta Thalassemia

Occurs when there's a problem with the production of beta globin chains. Thalassemia and sickle cell anemia are genetic disorders caused by errors in the genes for hemoglobin. The infusion of cord blood stem cells has shown the potential to replace the defective cells with healthy ones, improving oxygen transport and reducing the frequency of painful crises and transfusions associated with sickle cell anemia [*].

Additional types of anemia that can be treated with cord blood include:

  • Congenital Dyserythropoietic Anemia

  • Refractory Anemia with Excess Blasts (RAEB)

  • Congenital Dyserythropoietic Anemia

  • Refractory Anemia with Excess Blasts in Transition (RAEB-T)

  • Refractory Anemia with Ringed Sideroblasts (RARS)

In addition to anemia, these disorders are also being treated with cord blood stem cells (HSC’s) [*].

Cord Blood and Fanconi Anemia Success Story

The first successful cord blood transplant took place in France in 1988 and saved the life of American 5-year-old Matthew Farrow. This changed how the world viewed umbilical cord blood and launched a new potential for stem cell treatments. While Matthew has been integral as the voice of cord blood transplant success, there is a less heard voice behind the transplant that took place. Matthew’s sister was his donor, and while she was still so young, she knew she was integral in helping her brother.

Clinical Trials for Cord Blood and Anemia

Several clinical trials have been conducted to explore the efficacy of cord blood in treating different forms of anemia. Here are five noteworthy trials that have shown promising results:

1. Clinical Trial NCT02240938

This trial aimed to evaluate the safety and efficacy of cord blood transplantation in patients with various hematologic disorders, including severe aplastic anemia and thalassemia. The study aimed to assess engraftment, survival, and potential adverse effects.

2. Clinical Trial NCT03456843

This trial focused on the use of umbilical cord blood-derived stem cells in patients with severe aplastic anemia. The study aimed to determine the feasibility and safety of using cord blood stem cells as a source of hematopoietic stem cell transplantation in these patients.

3. Clinical Trial NCT02303335

This trial aimed to evaluate the use of umbilical cord blood transplantation in patients with Fanconi anemia. The study intended to assess engraftment, overall survival, and disease-free survival following transplantation.

4. Clinical Trial NCT02435932

This trial focused on the use of umbilical cord blood-derived stem cells in patients with beta-thalassemia major. The study aimed to evaluate the safety and efficacy of cord blood transplantation in these patients.

5. Clinical Trial NCT01806019

This trial aimed to assess the use of umbilical cord blood-derived stem cells in patients with sickle cell anemia. The study focused on evaluating engraftment, overall survival, and potential complications.

Please note that these are just a few examples of clinical trials that were ongoing or had been conducted involving cord blood stem cells and anemia. For the most up-to-date information on ongoing trials and their outcomes, we recommend searching clinical trial databases such as ClinicalTrials.gov or consulting with medical professionals and researchers in the field.
