Diagnosis of Pure Red Blood Cell Aplasia
- Complete blood count (CBC), reticulocyte count
- Bone marrow examination
What is pure red cell aplasia PRCA?
Pure red cell aplasia (PRCA) is a type of bone marrow failure syndrome (stem cell failure) and is characterized by severe normocytic, normochromic anemia associated with reticulocytopenia, and the absence of erythroblasts in otherwise normal bone marrow.
What are the different types of red cell aplasia?
There are three types of PRCA: Acquired Pure Red Cell Aplasia: This is an extremely rare type of Pure Red Cell Aplasia (PRCA) and it commonly affects adults. Patients with Acquired Pure Red Cell Aplasia will have absence of reticulocytes, which are red cell precursors, in the bone marrow.
Can You recover from pure red cell aplasia without knowing?
Patients having a normal functioning bone marrow and who get affected with transient Pure Red Cell Aplasia (PRCA) can recover without even knowing that they had it. However, this condition is dangerous for patients suffering from chronic hemolytic anemia.
What are the symptoms of pure red cell aplasia?
Certain congenital genetic disorders which are seen in early childhood increase the risk of PRCA. What are the Symptoms of Pure Red Cell Aplasia? Patients suffering from Pure Red Cell Aplasia will have anemia; and symptoms of anemia include: Pale skin (pallor), fatigue, shortness of breath and dizziness.
How do you test for pure red cell aplasia?
A bone marrow aspiration (removing a small amount of the liquid portion of bone marrow through a needle) can confirm the diagnosis if the number of red cell precursors in these samples is too low. A bone marrow biopsy can also test iron overload, which can be a complication in patients who need transfusions.
What are the symptoms of pure red cell aplasia?
Acquired Pure Red Cell Aplasia is a rare bone marrow disorder characterized by an isolated decline of red blood cells (erythrocytes) produced by the bone marrow. Affected individuals may experience fatigue, lethargy, and/or abnormal paleness of the skin (pallor).
What tests are done to diagnose aplastic anemia?
Bone marrow biopsy. The sample is examined under a microscope to rule out other blood-related diseases. In aplastic anemia, bone marrow contains fewer blood cells than normal. Confirming a diagnosis of aplastic anemia requires a bone marrow biopsy.
How common is pure red cell aplasia?
Acquired Pure Red Cell Aplasia: This is a very rare condition and usually affects adults. It is characterized by an absence of red cell precursors (reticulocytes) in the marrow and a low red blood cell count.
Can pure red cell aplasia be cured?
Treatment of Pure Red Blood Cell Aplasia Pure RBC aplasia secondary to parvovirus infection is treated with intravenous immune globulin. Thymectomy is done in patients with thymoma-associated pure RBC aplasia; most patients improve but are not always cured.
Is pure red cell aplasia fatal?
Abstract. Pure red-cell aplasia (PRCA) is a serious, life threatening rare condition of multifactorial causes manifested as severe anemia with absence of erythroid precursors in the bone marrow.
Which is the most common early symptom in aplastic anemia?

What is the life expectancy of someone with aplastic anemia?
What are the survival rates for aplastic anemia? Aplastic anemia is a life-threatening condition with very high death rates (about 70% within 1 year) if untreated. The overall five-year survival rate is about 80% for patients under age 20.
Can aplastic anemia be misdiagnosed?
It is often overlooked or misdiagnosed because of its varied and striking manifestations, which frequently mask completely the primary illness and cause it to be classed with other diseases, such as the infections or the hemorrhagic diseases.

What type of anemia is pure red cell aplasia?
Pure red cell aplasia (PRCA) is a rare disorder that designates anemia secondary to failure of erythropoiesis. It is characterized by normocytic, normochromic anemia, which is associated with reticulocytopenia in the peripheral blood and absent or infrequent erythroblasts in the bone marrow.
What is the condition called when you have a reduced number of red blood cells?
Pure red cell aplasia (PRCA) is a rare condition that affects the bone marrow. Bone marrow contains stem cells which develop into the red blood cells that carry oxygen through the body, the white blood cells that fight infections, and the platelets that help with blood clotting. In people with PRCA, the bone marrow makes a reduced number of red blood cells (called anemia ). As a result, affected people may experience fatigue, lethargy, and pale skin. [1] [2] PRCA has many different causes. A rare congenital form of PRCA, called Diamond Blackfan syndrome, is an inherited condition that is also associated with other physical abnormalities. PRCA can also be due to certain medications, infections, pregnancy, renal failure, and conditions such as thymomas, autoimmune disease (such as systemic lupus erythematosus ), cancers of the blood, and solid tumors. In many cases, the cause of the condition is unknown (idiopathic). [1] [3] The treatment of PRCA aims to address the underlying cause of the condition and relieve the associated signs and symptoms. [1]
What happens when you have PRCA?
As a result, affected people may experience fatigue, lethargy, and pale skin. [1] [2] PRCA has many different causes.
What is the autoimmune registry?
The Autoimmune Registry supports research for Pure red cell aplasia by collecting information about patients with this and other autoimmune diseases. You can join the registry to share your information with researchers and receive updates about participating in new research studies. Learn more about registries.
What are the red cells in PRCA?
Red cells in PRCA are normochromic and normocytic. The absolute reticulocyte count is always less than 10 000/µL (reticulocyte percentage, <1%), and in many cases is much lower. The diagnosis of PRCA should be questioned with higher reticulocyte values or if the reticulocyte percentage is only less than 1% when corrected for the degree of anemia. In general, the white blood count, white blood cell differential, and platelet count are normal. In the setting of concurrent inflammation, there may be some modest reduction in the total white blood count or a mild abnormality (either slightly high or slightly low) in the platelet count. There may also be a mild relative lymphocytosis.
What is the treatment for PRCA?
DBA is typically treated with glucocorticoids, usually prednisone.
What is abnormal cytogenetics in bone marrow?
Abnormal cytogenetics in the setting of a characteristic marrow for PRCA indicates the myelodysplastic variant of PRCA. If increased lymphocytes or plasma cells are present, they should be polyclonal in acquired immune PRCA. If clonal lymphocytes are present, it suggests PRCA secondary to an associated lymphoproliferative disorder. T-cell-receptor gene rearrangement studies should be performed routinely. 17
What is a PRCA?
Topics: Pure red cell aplasia (PRCA) is a syndrome defined by a normocytic normochromic anemia with severe reticulocytopenia and marked reduction or absence of erythroid precursors from the bone marrow. 1 Abnormalities from PRCA are limited to the red cell lineage; abnormalities in other cell lines usually reflect another concurrent disorder.
What is the difference between PRCA and Diamond Blackfan?
Pure red cell aplasia (PRCA) is a syndrome defined by a normocytic normochromic anemia with severe reticulocytopenia and marked reduction or absence of erythroid precursors from the bone marrow. Diamond-Blackfan anemia is a congenital form of PRCA. Acquired PRCA may be either a primary disorder or secondary to some other disorder or agent.
What is primary acquired PRCA?
This review will primarily focus on acquired PRCA. Primary acquired PRCA is an autoimmune disorder in which an immune mechanism interrupts erythroid differentiation. This may be mediated by an autoantibody or by another immunologic process. When an autoantibody is involved, the target of the autoantibody is variable and may be at the erythroid precursor level. 4 Myelodysplastic primary acquired PRCA is an uncommon presentation of myelodysplasia morphologically characterized by erythroid hypoplasia, but is pathophysiologically distinct from the other types of PRCA described in this discussion. 5 Transient erythroblastopenia of childhood is an uncommon self-limited variant of primary acquired PRCA occurring between the ages of 3 months and 4 years. 6 Although familial cases have been reported, it appears to be an autoimmune disorder in most cases. 6
What is the most common type of lymphoproliferative disorder associated with PRCA?
The lymphoproliferative disorders most frequently associated with PRCA are chronic lymphocytic leukemia and large granular lymphocyte (LGL) leukemia, 15, 16 although it has been reported with Hodgkin and non-Hodgkin lymphoma, as well as Waldenstrom macroglobulinemia, as outlined in Table 1. A number of small studies have suggested an increased frequency of otherwise unapparent clonal T-cell disorders in primary acquired PRCA. 17 PRCA is typically immune mediated in these cases, although usually not by antibody-dependent mechanisms. 18
What are the symptoms of pure red cell aplasia?
What are the Sign and Symptoms of Pure Red Cell Aplasia? The signs and symptoms associated with Pure Red Cell Aplasia may include: Generalized weakness in the body. Changes in skin tone.
How can Pure Red Cell Aplasia be Prevented?
Being able to identify it early in life will help with treatment, to keep the condition either suppressed or maintained so that it does not develop into a chronic form or give rise to other health conditions.
What are the possible Complications of Pure Red Cell Aplasia?
The possible complications associated with Pure Red Cell Aplasia may include:
What is the condition where red blood cells are released?
The red blood cells get released from the bone marrow and circulate in the body to deliver oxygen. Pure Red Blood Cell Aplasia (PRCA) is an uncommon condition that results due to a defect in the bone marrow. PRCA arises when damage occurs to the bone marrow, where it is unable to produce a sufficient amount of red blood cells.
Why does red blood cell aplasia occur?
Pure Red Blood Cell Aplasia could occur as a result of a defect at birth, or develop over time associated with an autoimmune disorder, or as a transient and reversible condition following viral infections ...
How to tell if you have PRCA?
A physician may diagnose the condition by a thorough physical examination, assessment of family and/or medical history, monitoring heart and lung function, bone marrow function, etc.
How to treat pure red cell alopecia?
The treatment of Pure Red Cell Aplasia may be undertaken as: If the cause of Pure Red Cell Aplasia is an autoimmune-related disorder, medications such as steroids can be provided to help reduce the symptoms. Other medications, such as drugs that will suppress the immune response, could be administered to help the individual overcome the condition.
How is Pure Red Cell Aplasia Treated?
The aim of treatment of Pure Red Cell Aplasia is restoring the production of red blood cells and treating any underlying disorder. The common treatments done for Pure Red Cell Aplasia are:
What is Pure Red Cell Aplasia?
This is a form of anemia in which the bone marrow stops making red blood cells and this condition is known as Pure Red Cell Aplasia (PRCA). This results in anemia and reticulocytopenia, which is a condition where there is absence of young red cells.
What are the Risk Factors for PRCA?
Patients with autoimmune disorders, such as rheumatoid arthritis, are at increased risk for having Pure Red Cell Aplasia (PRCA).
What is the difference between aplastic anemia and pure red cell anemia?
The primary difference between aplastic anemia and Pure Red Cell Aplasia is that, in PRCA , only the red blood cells group is affected and the platelets and WBCs remain at normal levels; hence the name Pure Red Cell Aplasia. Whereas in aplastic anemia, all three types of blood cells are usually affected.
What is the most common type of pure red cell aplasia?
Acute or Transient Self-Limited Pure Red Cell Aplasia (PRCA): This is the commonest type of Pure Red Cell Aplasia and is similar to acquired PRCA and differs only where at some point in time transient self-limited PRCA goes away on its own. A virus or drug triggers transient Pure Red Cell Aplasia (PRCA). Most of the times, after the offending drug is stopped or after the virus clears the transient Pure Red Cell Aplasia (PRCA) will disappear. Patients having a normal functioning bone marrow and who get affected with transient Pure Red Cell Aplasia (PRCA) can recover without even knowing that they had it. However, this condition is dangerous for patients suffering from chronic hemolytic anemia.
What is the best treatment for PRCA?
Immunosuppressive therapy is done if the underlying cause of the PRCA is immunological and if the patient is not responding to corticosteroids. Other medications for PRCA comprise of azathioprine, cyclosporine, cyclophosphamide with or without corticosteroids, and anti-thymocyte globulin. Rituximab may be effective in some patients. If virus is the cause of PRCA (especially B19 parvovirus) then immunoglobulin infusions are given for treatment. Surgery is needed for treating thymoma-associated PCRA where the thymoma is removed surgically. After immunosuppressive therapy there is significant relapse rate, however, treatments can be repeated.
What is a reticulocyte count?
A reticulocyte count is done to determine the number of young red cells present in the patient.
Abstract
Pure red cell aplasia (PRCA) is a rare hematological disorder with multiple etiologies. The multifaceted nature of this disease is emphasized by the variety of concomitant clinical features. Classic idiopathic presentation aside, prompt recognition of pathogenetic clues is important because of their diagnostic and therapeutic implications.
