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.

Further study details as provided by Adam Esbenshade, Vanderbilt University:

Primary Outcome Measures:
  • 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
  • Major risk factors for developing methemoglobinemia

Enrollment: 41
Actual Study Start Date: January 2009
Study Completion Date: December 2009
Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
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.


Ages Eligible for Study:   up to 18 Years   (Child, Adult)
