Regarding health check-ups and thalassemia?


I have mild thalassemia, but I do not have any noticeable symptoms and live like an average person.
I usually sleep 6 to 8 hours and exercise regularly.
I do not smoke, drink alcohol, chew betel nut, or consume coffee; I only drink water.
However, in recent years, some of the results from my health check-ups have raised my concerns.
Below are the abnormal values from this year's check-up report:
- Red Blood Cell Count (RBC): 6.29 (4.2–6.2 x 10^6/µL)
- Mean Corpuscular Hemoglobin (MCH): 21.3 (26.0–34.0 pg)
- Mean Corpuscular Volume (MCV): 67.7 (79.0–99.0 fL)
- Alkaline Phosphatase (ALP): 38 (40–129 U/L)
- Total Bilirubin (T-BIL): 1.22 (<1.2 mg/dL)
- Direct Bilirubin (D-BIL): 0.39 (0–0.30 mg/dL)
I would like to know if thalassemia can affect alkaline phosphatase and bilirubin levels.
I have been undergoing these tests for over six years, and while some years the alkaline phosphatase and bilirubin levels are normal, other years they show abnormal values similar to these.
I do not feel any physical abnormalities, which makes me wonder if this is caused by thalassemia.
Regardless of whether it is or not, should I visit a clinic for further examination, or is it sufficient to just monitor the situation? If I need to go to a clinic, should I see a hepatologist, an internist, or a family medicine physician? I would appreciate your advice! Thank you!

A mild increase should not be a concern; just monitor it.

More Info


Mediterranean anemia, also known as thalassemia, is a genetic blood disorder characterized by reduced production of hemoglobin, which can lead to anemia. Individuals with mild forms of this condition often live normal lives without significant symptoms. However, as you've noted, routine health checks can reveal abnormal laboratory results, particularly concerning red blood cell counts, hemoglobin levels, and other related parameters.

In your case, the lab results indicate a red blood cell (RBC) count of 6.29 million cells per microliter, which is slightly above the normal range. This can be typical in individuals with thalassemia, as the body compensates for the reduced hemoglobin by producing more red blood cells. However, the mean corpuscular hemoglobin (MCH) and mean corpuscular volume (MCV) values are below the normal range, which is consistent with microcytic anemia often seen in thalassemia.
Regarding your specific questions about alkaline phosphatase (ALP) and bilirubin levels, it is important to understand that while thalassemia primarily affects red blood cell production and hemoglobin levels, it can also have secondary effects on other blood parameters.
1. Alkaline Phosphatase (ALP): This enzyme is primarily associated with the liver, bones, and bile ducts. Abnormal ALP levels can indicate liver disease, bone disorders, or bile duct obstruction. While thalassemia itself does not directly cause elevated ALP, the presence of other conditions or complications related to thalassemia, such as liver issues due to iron overload from repeated blood transfusions, could potentially affect ALP levels.
2. Bilirubin Levels: Elevated bilirubin levels can occur in thalassemia due to increased breakdown of red blood cells (hemolysis). In your case, the total bilirubin level is slightly elevated, and the direct bilirubin is above the normal range. This could suggest some degree of hemolysis or liver function issues, which may or may not be directly related to your thalassemia.
Given your history of fluctuating ALP and bilirubin levels, it is advisable to consult with a healthcare provider for further evaluation. While mild thalassemia may not require extensive treatment, monitoring liver function and ensuring that there are no complications from the condition is essential.

Recommendations:
- Follow-Up Appointments: It would be prudent to schedule a follow-up appointment with a healthcare provider. Given your symptoms and lab results, a visit to a hematologist would be beneficial, as they specialize in blood disorders and can provide insights into the implications of your thalassemia on your overall health.


- Further Testing: Depending on the findings during your appointment, your doctor may recommend additional tests, such as liver function tests, iron studies, or imaging studies to assess liver health.

- Specialist Consultation: If liver function tests are abnormal, you may also be referred to a gastroenterologist or hepatologist for further evaluation. If the primary concern is related to blood parameters, a hematologist would be the most appropriate specialist.

In summary, while mild Mediterranean anemia may not directly cause abnormal ALP or bilirubin levels, it is essential to monitor these parameters closely. Consulting with a healthcare provider will help clarify the situation and determine whether further investigation is necessary. Regular follow-ups and appropriate testing can ensure that any potential complications are addressed promptly.
