Leukopenia (Sean Phua's Group)

Group 1: Sean Phua, Elgin Patt, Neo Wei Hong, Liau Zheng En, Shawn Lim
Leukopenia
i.
What is the cause of the disease?
Ans: The reduction of white blood cells in the human body can be caused by cancer treatment like chemotherapy or radiation therapy
as malignant cells overwhelm the bone marrow. Some illness like influenza or Hodgkin's lyphoma (a type of cancer that originates from lymphocytes) can also cause the reduction of white blood cells. Some medications like immunosuppresive drugs, such as sirolimus, mycophenolate mofetil, tacrolimus, and cyclosporine can also cause leukopenia. Leukopenia increases the chance of the patient getting an infection.

ii. How does the component of blood/ blood vessel affected in the disease?
Pseudoleukopenia can develop upon the onset of infection. The leukocytes are marginalized in the blood vessels so that they can scan for the site of infection. This means that even though there is increased white blood cell production, it will appear as though the white blood cell count is low from a blood sample, since the blood sample is of core blood and does not include the marginalized leukocytes.

iii. What is the function of the blood component/ structure in circulatory system?
White blood cells, or leukocytes, are cells of the immune system that defend the body against both infectious disease and foreign materials.

v. How will the absence of the blood component / structure affect the health of the patient?
With the decrease of white blood cells, the immune system becomes weak.
With a weakened immune system, a person becomes much more vulnerable to even relatively minor infections.

  1. I've learnt that Leukopenia can be caused by cancer treatments like chemotherapy and radiation therapy. Also, lymphocytes can cause Leukopenia.

  2. I've learnt that
    1.Leukopenia is a disease were there is a decreased number of white blood cells
    2. People suffering from this disease will be more vulnerable to minor infections.

  3. 1) I've learnt that white blood cells are very important.

    2) Without white blood cells, the immune system becomes weak.

  5. 1) I learnt that white blood cells are vital as they make your body immune to infections.

    2) I learnt that without white blood cells, a person will become very vulnerable and weak.

  7. I've learnt that when the white blood cells decrease, the patient will be more vulnerable and will fall sick easily.

  8. 1. Chemotherapy that is supposed to help patients may cause them to contract another disease like Leukopenia.
    2. I know the the true importance of white blood cells.

  9. I learnt that when a person's immune system is weakened,even a small infection can be dangerous.

  10. I've learnt:
    1) absence of the blood component will cause immune systems to become weak
    2) the white blood cells are cells of the immune system which defend the body against diseases and foreign materials

  11. I've learnt that leukopenia can be started from a bad chemical reaction and the white blood cells fall to a critical level. The not only genes cause it, common flu can also cause it.

  12. I've learnt that leukopenia is caused by the lack and reduction of the white blood in the body of the patient.

  16. I've have learnt that Leukopenia is cause by the reduction in the number of white cells.

  17. i have learnt that leukopenia is caused by the reduction of white blood cells, as the immune system becomes weaker due to the lack of white blood cells

  18. I've that our immune system will becomes weaker if we caught the disease.
