Frequently Asked Questions (FAQ) :
A: Warm AIHA involves antibodies that attack red blood cells at normal body temperature, often associated with autoimmune diseases. Cold AIHA involves antibodies that are more active in cooler temperatures, typically triggered by infections or cold exposure.
A: Management involves regular monitoring, adjusting immunosuppressive therapy, and avoiding triggers like certain medications or cold exposure. Long-term follow-up with a hematologist is essential for ongoing care.
Yes, if left untreated, AIHA can lead to severe anemia and complications. However, with proper treatment, most patients can achieve remission and lead normal lives.
Yes, treatments like splenectomy carry risks such as increased susceptibility to infections. Patients are often vaccinated against certain bacteria before undergoing this procedure.

Autoimmune Hemolytic Anemias :
Welcome to the specialized service page for Autoimmune Hemolytic Anemias (AIHA) treatment with Dr. Rahul Bhargava. Here, you will find detailed information about AIHA, its symptoms, diagnosis, treatment options, costs, and FAQs to guide you through understanding and managing this condition effectively
Understanding Autoimmune Hemolytic Anemias :
Autoimmune Hemolytic Anemia (AIHA) is a rare but serious condition where the immune system mistakenly attacks and destroys red blood cells. This destruction exceeds the bone marrow’s ability to produce new red blood cells, leading to anemia. AIHA can be classified into two main types based on the temperature at which the antibodies are most active:
- Warm Autoimmune Hemolytic Anemia: The antibodies attack red blood cells at normal body temperature.
- Cold Autoimmune Hemolytic Anemia: The antibodies are most active at cooler temperatures, often causing symptoms in response to cold exposure.
Causes of AIHA :
The exact cause of AIHA is often unknown (idiopathic), but it can be associated with:
- Autoimmune Diseases: Such as lupus or rheumatoid arthritis.
- Infections: Viral infections like Epstein-Barr virus.
- Medications: Certain drugs like penicillin or methyldopa.
Cancers: Such as lymphoma or leukemia.
Types of Autoimmune Hemolytic Anemia (AIHA) :
- Warm Autoimmune Hemolytic Anemia (Warm AIHA):
In this type, antibodies attack red blood cells at normal body temperature (around 37°C). It is the more common form of AIHA. - Cold Autoimmune Hemolytic Anemia (Cold AIHA):
In this type, antibodies become active and attack red blood cells at lower temperatures, typically below 30°C. This form is less common and symptoms often worsen with cold exposure.
- Warm Autoimmune Hemolytic Anemia (Warm AIHA):
Symptoms of Autoimmune Hemolytic Anemias :
- Fatigue and Weakness: Due to a reduced number of red blood cells.
- Shortness of Breath: Even with mild exertion.
- Pale or Yellow Skin (Jaundice): Resulting from the breakdown of red blood cells.
- Dark-Colored Urine: Due to hemoglobin released from destroyed red blood cells.
- Rapid Heartbeat: As the heart compensates for low oxygen levels.
- Dizziness or Lightheadedness: From decreased oxygen delivery to the brain.
- Enlarged Spleen or Liver: As these organs work to filter out damaged red blood cells.
Diagnosing Autoimmune Hemolytic Anemias :
Accurate diagnosis of AIHA involves several steps:
1. Medical History and Physical Examination
A thorough review of your medical history and a physical exam to identify signs of anemia, such as pale skin and an enlarged spleen or liver.
2. Blood Tests
- Complete Blood Count (CBC): To measure levels of red blood cells, hemoglobin, and hematocrit.
- Reticulocyte Count: To evaluate bone marrow function.
- Peripheral Blood Smear: To examine the shape and characteristics of red blood cells.
- Direct Antiglobulin Test (Coombs Test): To detect antibodies attached to red blood cells, confirming AIHA.
- Indirect Coombs Test: To detect free-floating antibodies in the blood.
3. Bone Marrow Examination
In some cases, a bone marrow biopsy may be performed to assess the production of blood cells and rule out other conditions.
Treatment Options for Autoimmune Hemolytic Anemias :
Dr. Rahul Bhargava provides comprehensive and personalized treatment plans for AIHA, focusing on the underlying cause and severity of the condition. Treatment options include:
1. Corticosteroids
Corticosteroids like prednisone are the first-line treatment to reduce immune system activity and decrease red blood cell destruction. The dosage and duration depend on the patient’s response.
2. Immunosuppressive Drugs
If corticosteroids are not effective, immunosuppressive drugs such as azathioprine or cyclophosphamide may be used to further suppress the immune system.
3. Intravenous Immunoglobulin (IVIG)
IVIG is administered to provide temporary relief by neutralizing the antibodies attacking red blood cells. This treatment is often used in acute cases or when rapid improvement is needed.
4. Blood Transfusions
In severe cases, blood transfusions may be necessary to quickly increase red blood cell count and alleviate symptoms. This is typically a short-term solution while other treatments take effect.
5. Plasmapheresis
Plasmapheresis is a procedure that filters the blood to remove harmful antibodies. It is usually reserved for severe cases or when other treatments have failed.
6. Splenectomy
For patients with refractory AIHA, a splenectomy (surgical removal of the spleen) may be considered. The spleen is responsible for filtering and destroying abnormal red blood cells, and its removal can reduce hemolysis.
