Workup

  • Anemia is often an incidental finding made on CBC that requires further workup to determine the cause.[amboss.com]

  • […] specificity for the diagnosis of iron deficiency; a serum ferritin concentration of 15 ng/mL has a sens of 59% and a spec of 99 % for iron deficiency Transferrin: ferritin index: 2 suggests IDA This is NOT a diagnosis by itself, it must include an appropriate workup[errolozdalga.com]
  • Workup may include a complete blood count (CBC), peripheral smear, iron studies (eg, ferritin and total iron-binding capacity [TIBC]), bone marrow aspiration and biopsy, and other studies as appropriate.[emedicine.medscape.com]

  • […] can be congenital, acquired causes are usually drug induced (including copper deficiency, zinc toxicity, etoh) or due to MDS Thalassemia: iron and ferritin should be nl, retic index is high, HgA2 increased Iron Deficiency anemia: Lab findings include: microcytosis[errolozdalga.com]
  • Deletion of two genes (alpha thalassaemia trait) causes a more marked microcytosis (MCV 65 – 78) and hypochromia.[bpac.org.nz]

Treatment

  • Which treatment must I follow if I have the disease? Treatment is supportive and involves haematological monitoring with regular blood transfusions. The inclusion of EPO treatment may decrease the number of required blood transfusions.[enerca.org]

Prognosis

  • Few patients are eligible for transplant. [ 1 ] Prognosis [ 9 ] The prognosis is very variable. Reversible causes (eg, alcohol or drugs) appear to have no long-term effects if the underlying cause is successfully treated or removed.[patient.info]
  • Prognosis The prognosis of sideroblastic anemia is highly variable. Reversible causes such as alcohol and drugs do not appear to carry long-term sequelae.[emedicine.medscape.com]
  • Course and prognosis Sideroblastic anemias are often described as responsive or non-responsive in terms of increased hemoglobin levels to pharmacological doses of vitamin B 6. 1- Congenital: 80% are responsive, though the anemia does not completely resolve[ipfs.io]
  • Therapeutic phlebotomy can be used to manage iron overload. [17] Prognosis [ edit ] Sideroblastic anemias are often described as responsive or non-responsive in terms of increased hemoglobin levels to pharmacological doses of vitamin B 6. 1- Congenital[en.wikipedia.org]
  • Relevance of autoimmune disorders with prognosis of MDS is disputable. Their response to immunosuppressive therapy is good [ 72 ]. In MDS, not only the stem cells but an inflammatory microenvironment is also involved.[intechopen.com]

Prevention

  • The early detection of these cases may lead to early institution of pyridoxine, which may be therapeutic in many cases of congenital sideroblastic anemia and prevent long-term complications of anemia. [Figure 1][jahjournal.org]
  • Treatment for PNH is eculizumab, a monoclonal antibody to prevent conversion of C5 to C5a. They may also be prescribed immunosuppressive therapy. In severe cases, a bone marrow transplant is needed.[nextgencombatmedic.com]
  • Although adequate iron is present, a mitochondrial defect (decreased activity of D-ALA or ferrochelatase) prevents the incorporation of iron into hemoglobin.[med-ed.virginia.edu]
