Further Inpatient Care

  • Inpatient care of people with hereditary pyropoikilocytosis consists largely of transfusion requirements, care immediately after splenectomy, and treatment of illnesses that result from severe anemia or complications related to splenectomy.

Further Outpatient Care

  • Provide routine outpatient care and monitor hemoglobin if symptoms occur.
  • Maintain high suspicion for early involvement with gallbladder disease.
  • Iron chelation therapy may be required to prevent irreversible end-organ damage due to transfusion-induced hemosiderosis. Monitor the number of transfusions performed and the iron status of the patient to determine if and when this therapy is needed.
  • If a splenectomy has been performed, polyvalent pneumococcal polysaccharide vaccine (Pneumovax) therapy and prompt care of febrile illnesses is warranted.

Inpatient & Outpatient Medications

  • No specific medications are used to treat people with hereditary pyropoikilocytosis. The need for treatment with medications is patient-specific and based on individual complications.
  • Folic acid is often used to prevent folic acid deficiency that may occur as a result of increased erythropoiesis.
  • Iron chelation therapy may be necessary in patients who develop significant iron overload from red blood cell transfusions.

Complications

  • Most complications are related either to extended severe anemia with multiple resultant transfusions and iron toxicity to major organs or to infection with encapsulated organisms in patients who have undergone a splenectomy, although such infections are rare in patients who have been immunized against pneumococcus, Haemophilus influenzae, meningococcus, or a combination thereof.

Prognosis

  • Prognosis is related to the number of transfusions needed to maintain adequate hemoglobin levels for a growing child and the ability to treat or to prevent life-threatening infections after splenectomy.

Patient Education

  • Discuss with the patient's parents the possibility that they could bear another child with the same disease.
