Diamond-Blackfan Anaemia: Symptoms, Causes, Diagnosis & Treatment

Diamond-Blackfan Anaemia (DBA) is a rare inherited bone marrow failure syndrome that primarily affects the body’s ability to produce red blood cells. It commonly develops during infancy or early childhood and may cause severe anaemia, pallor, fatigue, poor feeding and growth problems. Some children with Diamond-Blackfan Anaemia may also have congenital abnormalities involving the thumbs or upper limbs, heart, kidneys, face or other parts of the body.

Early diagnosis and appropriate specialist care are important because DBA can require long-term management with blood transfusions, corticosteroid therapy, iron overload monitoring and, in selected patients, haematopoietic stem cell transplantation (HSCT).

If your child has persistent or unexplained anaemia, a low reticulocyte count, repeated blood transfusion requirements or a suspected inherited bone marrow disorder, evaluation by an experienced paediatric haematology specialist can help determine the appropriate treatment approach.

What Is Diamond-Blackfan Anaemia?

Diamond-Blackfan Anaemia is a rare inherited disorder in which the bone marrow has difficulty producing red blood cells. It is classified among the inherited bone marrow failure syndromes and is often recognised during infancy.

Red blood cells carry oxygen throughout the body. When their production is significantly reduced, a child can develop anaemia, resulting in symptoms such as pale skin, tiredness, weakness, poor feeding or breathlessness. DBA is more than an isolated red blood cell disorder. Some affected children can have congenital abnormalities or other health problems, while the severity of symptoms can vary considerably between individuals.

The term Diamond-Blackfan Anaemia syndrome (DBAS) is increasingly used to describe the broader range of clinical features and genetic findings associated with the condition. Not every person with a DBA-associated genetic change will necessarily have the same degree of anaemia or the same physical features.

What Causes Diamond-Blackfan Anaemia?

Diamond-Blackfan Anaemia is usually associated with changes in genes involved in the production and function of ribosomal proteins. These genetic changes can interfere with normal blood-cell development, particularly the production of red blood cells.

What Are the Symptoms of Diamond-Blackfan Anaemia?

Diamond-Blackfan anemia symptoms can vary from child to child. Many children develop signs of anaemia during infancy or early childhood.

Common symptoms and signs may include:

• Pale skin or pallor
• Tiredness and weakness
• Poor feeding in infants
• Irritability or reduced activity
• Rapid heartbeat
• Breathlessness
• Poor weight gain
• Growth problems
• Low haemoglobin levels
• A low reticulocyte count

Some children may also have congenital abnormalities. These can include differences involving the thumbs or upper limbs, heart abnormalities, kidney or urinary-system abnormalities, facial features or abnormalities of the palate.

Importantly, not every child with Diamond-Blackfan Anaemia will have physical abnormalities. The condition has a broad clinical spectrum, which is why a thorough medical and genetic evaluation is important. 

How Is Diamond-Blackfan Anaemia Diagnosed?

Diagnosing Diamond-Blackfan Anaemia requires a combination of clinical assessment, blood investigations and, when appropriate, genetic and bone marrow testing.

• Blood Tests for Diamond-Blackfan Anaemia

A complete blood count (CBC) can identify anaemia and provide information about the red blood cells, white blood cells and platelets.

A reticulocyte count is particularly important because reticulocytes are newly produced red blood cells. A low reticulocyte count can indicate inadequate red blood cell production by the bone marrow.

Other laboratory investigations may be recommended depending on the child’s presentation.

• Genetic Testing for Diamond-Blackfan Anaemia

Genetic testing can identify changes in genes associated with DBA and may help confirm the diagnosis in a child with a suggestive clinical picture.

Genetic results should be interpreted by clinicians with experience in inherited bone marrow failure syndromes because not every genetic finding has the same clinical significance.

• Bone Marrow Examination

A bone marrow aspiration or biopsy may be recommended in selected children. It can help assess blood-cell production and distinguish Diamond-Blackfan Anaemia from other causes of bone marrow failure or anaemia.

Depending on the clinical situation, doctors may also recommend investigations such as eADA testing and assessment for congenital abnormalities or other inherited disorders that can resemble DBA.

What Is the Treatment for Diamond-Blackfan Anaemia?

Diamond-Blackfan anemia treatment is individualised according to the child’s age, severity of anaemia, response to treatment, transfusion requirements, genetic and clinical findings, and overall health.

The main established approaches include corticosteroid therapy, red blood cell transfusions with appropriate management of iron overload, and haematopoietic stem cell transplantation.

• Red Blood Cell Transfusions

Red blood cell transfusions can provide healthy red blood cells when the child’s bone marrow cannot produce enough.

• Managing Iron Overload

Children who require repeated blood transfusions can accumulate excess iron. Iron overload can affect organs such as the liver, heart and endocrine system if it is not identified and managed appropriately.

• Stem Cell Transplantation for DBA

Haematopoietic stem cell transplantation (HSCT), also referred to as a bone marrow transplant or stem cell transplant, can be considered for selected patients with Diamond-Blackfan Anaemia.

HSCT is not automatically required for every child with DBA. The decision depends on factors such as transfusion dependence, response or intolerance to corticosteroids, complications of treatment, the presence of significant additional disease and donor considerations.

Current international consensus guidance recommends individual assessment because the potential benefits and risks of HSCT need to be carefully balanced for each patient. 

Diamond-Blackfan Anaemia vs Iron-Deficiency Anaemia

Diamond-Blackfan Anaemia and iron-deficiency anaemia are different conditions and require different approaches to diagnosis and treatment.

Iron-deficiency anaemia occurs when the body does not have enough iron to produce haemoglobin effectively. Diamond-Blackfan Anaemia is an inherited disorder involving impaired red blood cell production by the bone marrow.

A child with persistent anaemia that does not fit the expected pattern of nutritional or iron-deficiency anaemia may require further evaluation by a paediatric haematologist.

Diamond-Blackfan Anaemia vs Fanconi Anaemia

Diamond-Blackfan Anaemia and Fanconi Anaemia are both inherited bone marrow failure syndromes, but they are distinct disorders with different genetic causes, clinical features and management considerations.

DBA primarily affects red blood cell production, particularly in its classic presentation, while Fanconi Anaemia can involve multiple blood-cell lineages and has its own characteristic congenital and cancer-predisposition features.

Long-Term Management and Complications of Diamond-Blackfan Anaemia

Long-term management of DBA goes beyond treating low haemoglobin.

Children may need regular monitoring of:

• Complete blood counts
• Treatment response
• Iron overload
• Growth and development
• Bone health
• Endocrine function
• Cardiac and other organ health when clinically indicated
• Associated congenital abnormalities
• Long-term complications and cancer risk

The 2024 international consensus statement recommends systematic surveillance because Diamond-Blackfan Anaemia syndrome can be associated with complications affecting different organ systems and an increased risk of certain malignancies.

When Should a Child With Diamond-Blackfan Anaemia See a Specialist?

Parents should consider specialist evaluation for DBA when a child has persistent or unexplained anaemia, an unusually low reticulocyte count, recurrent transfusion requirements, suspected inherited bone marrow failure, congenital abnormalities associated with DBA, or a confirmed DBA-associated genetic variant.

A paediatric haematologist can assess the child’s blood counts, medical history, genetic findings and treatment needs. Where stem cell transplantation may become relevant, assessment by a team with appropriate paediatric haematology and bone marrow transplant expertise can help families understand the available options.

For families looking for Diamond-Blackfan anemia treatment in Delhi NCR, specialist evaluation can help determine whether the child’s anaemia is related to DBA and whether genetic testing, transfusion support, corticosteroid therapy or consideration of HSCT is appropriate.
