From the Guidelines
Platelet transfusions are generally not recommended for Immune Thrombocytopenic Purpura (ITP) except in cases of life-threatening bleeding or before urgent surgical procedures. In ITP, the immune system destroys platelets and has a shortened survival time in circulation, so transfused platelets will also be rapidly destroyed, making transfusions ineffective for sustained platelet count improvement 1. The American Society of Hematology 2011 evidence-based practice guideline for immune thrombocytopenia suggests that platelet transfusions may be considered in emergency situations, such as life-threatening bleeding, but their effect on the platelet count is short-lived 1.
Some key points to consider in the management of ITP include:
- First-line treatments for ITP include corticosteroids, intravenous immunoglobulin (IVIG), or anti-D immunoglobulin in Rh-positive non-splenectomized patients 1
- Second-line options include thrombopoietin receptor agonists, rituximab, or splenectomy
- The management should focus on treating the underlying autoimmune process rather than temporarily replacing platelets
- If platelet transfusions are absolutely necessary in emergency situations, they should be given along with immunosuppressive therapy to maximize their effectiveness 1
In emergency situations, such as life-threatening bleeding, the treatment options are limited, and physicians may wish to try treatments with evidence limited to case reports but which may be in theory more rapidly acting than IVIg and/or corticosteroids 1. However, the primary goal should always be to treat the underlying autoimmune process to achieve a sustained improvement in platelet count and reduce the risk of morbidity and mortality.
From the FDA Drug Label
Rescue therapies (i.e., corticosteroids, IVIG, platelet transfusions, and anti-D immunoglobulin) were permitted for bleeding, wet purpura, or if the patient was at immediate risk for hemorrhage.
The answer is yes, platelet transfusions can be given for Immune Thrombocytopenic Purpura (ITP) as a rescue therapy for bleeding, wet purpura, or if the patient is at immediate risk for hemorrhage 2.
From the Research
Platelet Transfusions for ITP
- Platelet transfusions are generally not the first line of treatment for Immune Thrombocytopenic Purpura (ITP) 3, 4, 5, 6.
- The primary goal of treatment in ITP is to increase the platelet count and reduce the risk of bleeding, rather than relying on platelet transfusions 3, 4, 5, 6.
- Treatment options for ITP include oral corticosteroids, intravenous immunoglobulin, anti-D immunoglobulin, splenectomy, and thrombopoietin receptor agonists 3, 4, 5, 6.
- Platelet transfusions may be considered in certain situations, such as life-threatening bleeding or severe thrombocytopenia, but this is not a common practice 3, 4, 5, 6.
Specific Treatment Options
- Corticosteroids are often used as the initial treatment for ITP, with the goal of increasing the platelet count and reducing the risk of bleeding 3, 4, 5, 6.
- Intravenous immunoglobulin and anti-D immunoglobulin can also be used to increase the platelet count, particularly in patients who require rapid increases in platelet counts 3, 4, 5, 6.
- Splenectomy is a surgical option for patients with ITP who do not respond to other treatments, but it is not without risks and is typically reserved for patients with severe disease 3, 4, 5, 6.
Recent Advances in ITP Management
- Recent studies have highlighted the importance of individualized treatment plans for ITP patients, taking into account factors such as age, platelet count, risk of bleeding, and comorbidities 5, 6.
- New treatments, such as thrombopoietin receptor agonists and fostamatinib, have been approved for use in adult patients with ITP, offering alternative options to splenectomy 5, 6.
- Ongoing research is focused on developing more effective and targeted treatments for ITP, including gene editing, bispecific antibody therapies, and cellular therapy 5.
