Which Vitamin Deficiency Causes Thrombocytopenia?
A deficiency in vitamin B12 can cause thrombocytopenia. This is supported by numerous studies and medical resources.
Thrombocytopenia is a condition characterized by a lower-than-normal number of platelets in the blood. Platelets are crucial for blood clotting. Vitamin B12 is essential for the proper development and function of blood cells, including platelets. A deficiency in this vitamin can impair platelet production, leading to thrombocytopenia.
Several sources highlight the link between vitamin B12 deficiency and thrombocytopenia:
-
Medical literature: Studies show that vitamin B12 deficiency is associated with a range of hematologic abnormalities, including thrombocytopenia. [7] (Reference: Pernicious Anemia and Vitamin B12 Deficiency Presenting As… Dec 1, 2022). This is further supported by mentions of vitamin B12 and folate deficiencies causing thrombocytopenia in various other sources ([Diagnostic approach to thrombocytopenia in adults - UpToDate], [Thrombocytopenia - StatPearls - NCBI Bookshelf], [Causes of thrombocytopenia in children - UpToDate]).
-
Clinical presentations: Vitamin B12 deficiency can manifest as isolated thrombocytopenia, meaning it's the primary hematologic abnormality observed. ([Vitamin B12 Deficiency, a Rare Cause of Isolated ...]) However, it often presents alongside other blood cell deficiencies like anemia (low red blood cell count) and leukopenia (low white blood cell count). ([Vitamin B12 deficiency])
-
Mechanism: The exact mechanism isn't fully elucidated in all references, but the deficiency interferes with normal bone marrow function and, subsequently, with the production of various blood cell types, including platelets.
While other vitamin deficiencies like folate deficiency can also contribute to low platelet counts, vitamin B12 deficiency is a specifically implicated factor.
