Haematology

Anaemia and other blood disorders present a major clinical challenge, significantly affecting patients' quality of life and overall health.  

Among the leading causes of anaemia, deficiencies in iron and vitamin B12 play a critical role, as they directly impact the production of haemoglobin and the maturation of red blood cells. Iron is vital for red blood cell production, while vitamin B12 is essential for DNA synthesis and cell growth.  

Beyond these nutritional deficiencies, effectively managing anaemia requires a comprehensive approach that includes early detection, tailored treatment and appropriate nutritional support. 

Nutritional deficiencies and impact on haematology 

Addressing nutritional deficiencies early on and correcting them in a targeted way are crucial for preventing and treating any associated anaemia. 

Iron deficiency, for example, is a common cause of iron-deficiency anaemia and can lead to symptoms such as chronic fatigue, reduced oxygen delivery to tissues, compensatory tachycardia and weakened immune function.  

Vitamin B12 deficiency, which is essential for DNA synthesis and red blood cell production, can lead to megaloblastic anaemia, peripheral neuropathy, cognitive decline and impaired bone marrow function. 

In addition to iron and vitamin B12, other micronutrients play a vital role in blood cell production (hematopoiesis), including Folate (vitamin B9), Copper, Zinc and Vitamin C. 

Managing anaemia in haematology 

Anaemia can arise from various factors, including nutritional deficiencies, chronic conditions, blood disorders and cancer treatments. Effective management involves: 

  • Accurate diagnosis: Laboratory tests are crucial to assess blood count, ferritin, transferrin, vitamin B12, folate levels and other relevant markers. 

  • Iron therapy: Iron supplementation can be administered orally or intravenously, depending on the severity of the deficiency and the patient's ability to tolerate treatment. 

  • Vitamin B12 and folate supplementation: When deficiencies are confirmed, supplementation can be administered either orally or via intramuscular injections. 

  • Transfusion approaches: In cases of severe anaemia, blood transfusions may be required to rapidly restore haemoglobin levels. 

  • Treatment of underlying causes: If anaemia is secondary to chronic conditions (such as kidney failure or inflammatory diseases), addressing the root cause is crucial for effective treatment. 

Iron-Based Treatment Options in Hematology

The treatment of iron deficiency anemia in hematology relies on an approach known as iron replacement therapy, aimed at restoring iron stores and normalizing hemoglobin levels. Therapeutic options include both oral and intravenous iron supplementation, depending on the clinical status of the patient, the severity of the anemia, and individual tolerance.

 

In general, oral iron supplementation is considered the first-line therapy, particularly in mild to moderate cases, due to its effectiveness, ease of administration, and favorable safety profile. Modern oral iron formulations, often developed with technologies designed to enhance gastrointestinal tolerance and bioavailability, have significantly improved treatment adherence.

 

The selection of the most appropriate formulation should always be personalized based on the patient’s specific needs and comprehensive clinical evaluation. Indeed, the management of anemia in hematology requires a holistic approach that addresses not only the correction of hemoglobin deficits, but also the underlying causes and the patient’s overall nutritional status.

 

Timely identification of iron, vitamin B12, and other micronutrient deficiencies, combined with an effective and well-tolerated iron replacement strategy, is a cornerstone for improving clinical outcomes and enhancing the quality of life in hematology patients.
