Study Notes
- Cito Blastic Anemia is a type of blood disorder where there's a buildup of iron in immature red blood cells (rbcs), making them dysfunctional.
- Hemoglobin, the protein in rbcs responsible for carrying oxygen, is made up of hemes and globins.
- Hemoglobin synthesis occurs in both mitochondria and cytoplasm, requiring multiple enzymes to catalyze the process.
- Defective protoporphin synthesis in Cito Blastic Anemia impairs the incorporation of iron to form heme.
- Cito Blastic Anemia can be congenital (X-linked) or acquired (excessive alcohol use, Vitamin B6 deficiency, lead poisoning).
- Congenital form is caused by mutations in the Ala S2 Gene, affecting mainly boys due to their single X chromosome.
- Acquired causes damage the mitochondria, affecting their ability to synthesize heme.
- Excessive alcohol consumption can lead to nutritional deficiencies, affecting heme synthesis.
- Vitamin B6 deficiency can occur due to ionizing radiation treatment for tuberculosis.
- Lead poisoning denatures enzymes crucial for heme synthesis and causes a characteristic "basophilic stippling" on histology.
- The inability to incorporate iron into rbcs leads to the formation of ringed Cito blasts and papenheim bodies on histology.
- Diagnosis involves clinical judgment and laboratory findings, including complete blood count, peripheral blood smear, and iron studies.
- Treatment includes removal of toxins, administration of peroxidase, thiamine, and folic acid, and therapeutic phototherapy or bloodletting to manage iron overload.
- Severe cases may require bone marrow or liver transplant.
