FAQ: Which Mechanism Is Responsible For Thrombocytopenia In Vitamin B12 Deficiency?

Can Vitamin B12 deficiency cause thrombocytopenia?

Vitamin B12 deficiency has profound effects on the bone marrow, resulting in characteristic changes on the blood film. Not all of these features are always present. Thrombocytopenia is a documented feature of vitamin B12 deficiency.

What are the causes of thrombocytopenia?

What causes thrombocytopenia?

  • Alcohol use disorder and alcoholism.
  • Autoimmune disease which causes ITP.
  • Bone marrow diseases, including aplastic anemia, leukemia, certain lymphomas and myelodysplastic syndromes.
  • Cancer treatments like chemotherapy and radiation therapy.

What is the pathophysiology of the thrombocytopenia in megaloblastic anemia?

Conclusion: Both hypoproduction and ineffective thrombo poiesis are the underlying patho mechanisms in megaloblastic thrombocytopenia as evidenced by the marrow findings and platelet indices. Platelet indices are of significant discriminative value in differentiating the various causes of thrombocytopenias.

How does B12 deficiency cause demyelination?

Peripheral neuropathy is also a usual presentation of vitamin B12 deficiency. In this condition, the transmission of nerve signals between the spinal cord and different parts of the body is disrupted. The problem may be due to direct damage caused to the nerves or demyelination that leads to axonal damage.

What are the neurological symptoms of B12 deficiency?

A lack of vitamin B12 can cause neurological problems, which affect your nervous system, such as:

  • vision problems.
  • memory loss.
  • pins and needles (paraesthesia)
  • loss of physical co-ordination (ataxia), which can affect your whole body and cause difficulty speaking or walking.

What happens if you have thrombocytopenia?

If you have thrombocytopenia, you don’t have enough platelets in your blood. Platelets help your blood clot, which stops bleeding. For most people, it’s not a big problem. But if you have a severe form, you can bleed spontaneously in your eyes, gums, or bladder or bleed too much when youre injured.

Can Thrombocytopenia be cured?

People with mild thrombocytopenia might not need treatment. For people who do need treatment for thrombocytopenia, treatment depends on its cause and how severe it is. If your thrombocytopenia is caused by an underlying condition or a medication, addressing that cause might cure it.

Does thrombocytopenia go away?

It can last from days to years. The treatment for this condition also depends on its cause and severity. Mild thrombocytopenia often doesn’t require treatment. If the condition causes or puts you at risk for serious bleeding, you may need medicines or blood or platelet transfusions.

What are the signs and symptoms of thrombocytopenia?

Thrombocytopenia signs and symptoms may include:

  • Easy or excessive bruising (purpura)
  • Superficial bleeding into the skin that appears as a rash of pinpoint-sized reddish-purple spots (petechiae), usually on the lower legs.
  • Prolonged bleeding from cuts.
  • Bleeding from your gums or nose.
  • Blood in urine or stools.

Is Megaloblastic anemia serious?

Most cases of macrocytic anemia that are caused by vitamin B-12 and folate deficiencies can be treated and cured with diet and supplements. However, macrocytic anemias can cause long-term complications if left untreated. These complications can include permanent damage to your nervous system.

What factors may cause megaloblastic anemia?

Folic acid and vitamin B12 deficiencies are the leading causes of megaloblastic anemia. The leading cause of vitamin B12 deficiency is pernicious anemia caused by autoimmune destruction of gastric parietal cells. Excess cell turnover, increased demand, malabsorption, or a poor diet may cause folate deficiency.

What nutrient deficiency causes megaloblastic?

The most common causes of megaloblastic anemia are deficiency of either cobalamin (vitamin B12) or folate (vitamin B9). These two vitamins serve as building blocks and are essential for the production of healthy cells such as the precursors to red blood cells.

How long does it take to reverse B12 deficiency?

Recovery from vitamin B12 deficiency takes time and you may not experience any improvement during the first few months of treatment. Improvement may be gradual and may continue for up to six to 12 months.

Can B12 repair nerve damage?

Vitamin B12 Enhances Nerve Repair and Improves Functional Recovery After Traumatic Brain Injury by Inhibiting ER Stress-Induced Neuron Injury. Traumatic brain injury (TBI) is one of the most common causes of neurological damage in young human populations.

How much B12 should MS patients take?

Vitamin B12 is found in eggs, meat, poultry, shellfish and dairy products; the RDA is 2.4 micrograms per day for both men and women.
