Brief Summary:

RATIONALE: Gathering information about how often methemoglobinemia occurs in young patients receiving dapsone for hematologic cancer or aplastic anemia may help doctors learn more about the disease and plan the best treatment.

PURPOSE: This research study is looking at methemoglobinemia in young patients with hematologic cancer or aplastic anemia treated with dapsone.

Condition or disease Intervention/treatment
Chronic Myeloproliferative Disorders Leukemia Lymphoma Lymphoproliferative Disorder Methemoglobinemia Multiple Myeloma and Plasma Cell Neoplasm Myelodysplastic Syndromes Myelodysplastic/Myeloproliferative Neoplasms Nonmalignant Neoplasm Drug: chemotherapy Drug: dapsone Other: medical chart review Procedure: assessment of therapy complications

Detailed Description:


  • Define the incidence of methemoglobinemia in patients with hematologic malignancy or aplastic anemia who received dapsone prophylaxis through a retrospective chart review encompassing the last 15 years.
  • Identify major risk factors for developing methemoglobinemia.

OUTLINE: Medical charts are reviewed. Of particular interest is demographic information, reasons for beginning dapsone prophylaxis, duration of dapsone prophylaxis, dapsone dosing, methemoglobin level, and treatment with methylene blue.
