Thrombocytopenia of unknown etiology?
Hello, Dr.
Lin.
Recently, during a health check-up, I found that my platelet count has been continuously decreasing.
I went to the hematology-oncology department for tests, but they couldn't identify the cause and only advised me to continue monitoring.
Two years ago, I was found to have splenomegaly, but there have been no abnormalities since then.
My liver function test shows GPT at 65, and I do not have hepatitis B or C, but I have severe fatty liver.
Are these related?

Hello: May I ask your age? The reasons may vary depending on your age.
Also, could you please let me know what tests you have undergone and their results? Would it be possible for you to come in for a follow-up appointment? Thank you! Dr.

Dear Patient,
I understand your concerns regarding the unexplained decrease in your platelet count, especially given your medical history, including splenomegaly and elevated liver enzymes. Let’s break down the potential connections and considerations regarding your situation.
Understanding Platelet Count Decrease
A decrease in platelet count, known as thrombocytopenia, can arise from various causes, including:
1. Bone Marrow Disorders: Conditions affecting the bone marrow, such as aplastic anemia or malignancies, can lead to reduced platelet production.
2. Increased Destruction: Conditions like immune thrombocytopenic purpura (ITP) or certain infections can cause the body to destroy platelets faster than they can be produced.
3. Sequestration: An enlarged spleen (splenomegaly) can sequester (trap) more platelets, leading to lower counts in circulation.
4. Liver Disease: Liver dysfunction can affect platelet production and function, particularly in cases of cirrhosis or significant fatty liver disease.
Your Specific Case
Given your history of splenomegaly and elevated liver enzymes (GPT 65), it is essential to consider how these factors might relate to your thrombocytopenia:
- Splenomegaly: An enlarged spleen can sequester platelets, leading to a lower count in the bloodstream. If your spleen was previously noted to be enlarged but is currently normal, it may have been a transient issue, but it’s worth monitoring for any recurrence.
- Liver Function: Elevated liver enzymes, particularly in the context of severe fatty liver disease, can indicate liver dysfunction. The liver plays a crucial role in producing thrombopoietin, a hormone that stimulates platelet production. If liver function is compromised, it could contribute to lower platelet counts.
Next Steps
1. Continued Monitoring: Since your hematologist has advised continued monitoring, it is crucial to follow up regularly. Platelet counts can fluctuate, and ongoing assessment will help identify any trends or changes.
2. Further Investigations: If your platelet count continues to decline or if you develop symptoms (such as easy bruising, bleeding, or fatigue), further investigations may be warranted. This could include:
- Bone marrow biopsy to assess for production issues.
- Additional imaging studies to evaluate the spleen and liver.
- Tests for autoimmune conditions or infections that could lead to increased platelet destruction.
3. Lifestyle Modifications: Addressing your fatty liver through lifestyle changes, such as diet and exercise, can improve liver function and potentially have a positive effect on your platelet count. Reducing alcohol intake and managing weight can also be beneficial.
4. Consultation with Specialists: If your platelet count remains low without a clear cause, consider seeking a second opinion or consulting with a hematologist specializing in thrombocytopenia.
Conclusion
While the decrease in your platelet count is concerning, it is essential to approach this systematically. The relationship between your liver health, splenomegaly, and platelet count is complex, and ongoing monitoring and evaluation will be key in managing your health. Please continue to communicate with your healthcare providers, and do not hesitate to reach out if you have further questions or concerns.
Best wishes for your health and well-being.
