Aplastic anaemia is a very rare but life-threatening condition of the bone marrow that can lead to death within months if not appropriately managed. In this condition where the bone marrow fails to function effectively. This leads to inadequate red blood cells that cause low hemoglobin, low white blood cells that leads infections and low platelets that leads to bleeding. Infections specially fungal infections are the leading cause of death in these individuals. Bleeding can occur from gums, nose, or even brain. Because of these complications it is considered a medical emergency that needs urgent diagnosis and initiation of treatment.
The exact cause of aplastic anemia remains unknown. In children and young adults it may be a result of certain genetic defects in nearly 10-15% cases. In the remaining, it is a result of immune attack to the bone marrow stem cells. The high exposure rates of potentially stem cell toxic pesticides and heavy metals in India are implicated in the development of Aplastic Anemia and are thought to contribute to the high incidence of Aplastic Anemia in India as compared to Europe and America.
The first warning sign of aplastic anaemia may be detected by a simple complete blood count, but confirmation of diagnosis requires a simple bone marrow test, which in aplastic anaemia reveals a hypocellular or “empty” marrow filled with fat cells. The bone marrow test also helps to differentiate cases of aplastic anemia from other blood diseases specially blood cancers where the treatment is different. The main challenge in timely diagnosis is the lack of awareness of this condition in the community. Fatigue, shortness of breath, frequent infections, bruising, nosebleeds, bleeding gums, or prolonged bleeding from minor cuts are very common symptoms of aplastic anaemia, which are often blamed on stress, viral infections, or “low haemoglobin levels.”
After diagnosis, the extent of aplastic anaemia determines the urgency and treatment course. In some non-severe aplastic anaemia, monitoring may be the first course of action, but frequent follow-up is still necessary, as the disease may progress. In severe and very severe aplastic anaemia, urgent treatment is necessary else it is uniformly fatal .
Treatment regimens have improved greatly in the last few decades. For most patients who qualify, especially younger patients with a matching donor, allogeneic stem cell transplantation is a potential cure and is successful in upto 90% cases. In patients who cannot undergo a stem cell transplant, immunosuppressive therapy with horse or rabbit antibodies against immune attacking T cells along with certain oral tablets leads to significant improvement in blood cell counts in most patients and is effective in 60-80% cases.
Supportive care is also a crucial aspect of treatment for aplastic anaemia. This includes blood transfusion, infection prophylaxis, and close monitoring. These are not a substitute for definitive treatment but are necessary for stabilising patients until the bone marrow is restored.
Both the treatments whether a stem cell transplant or immunosuppressive therapy with antibodies need to be given as soon as the diagnosis is made. These treatments and before life threatening complications like infections or bleeding happens. Antibody treatment is usually not effective once the bone marrow reserve is completely destroyed.
However, the lack of access to effective care is still a significant issue. Many patients in smaller cities and rural areas do not get bone marrow tests on time, and as a result, they are either misdiagnosed or referred late. Even those who are diagnosed , they do not take timely treatment or discontinue their treatment that leads to poor outcomes and often death.
Enhancing access to testing, enhancing referrals to haematologists, and improving awareness among primary care physicians are essential in improving outcomes. Aplastic anaemia can be managed effectively only if it is diagnosed and treated promptly.
Increased awareness among patients, families, and healthcare professionals can alter the outcome of this disease. A low blood count should never be taken lightly. Infections, unexplained bruising, and bleeding are some of the symptoms that should be investigated immediately and not just dismissed. Aplastic anaemia is no longer a death sentence. With early detection and the right access to care, patients can live a long life with a good quality of life. The answer is early detection of the symptoms because in aplastic anaemia, time is of the essence.
