It is currently assumed that all patients are lactose intolerant post bone marrow transplantation. This pilot study is to assess what the incidence of lactose intolerance is after bone marrow transplantation in children. This will be done using a lactose breath test.

Condition Phase
Lactose Intolerance
Phase 1

Study Type: Observational
Study Design: Time Perspective: Prospective
Official Title: Prevalence of Lactose Intolerance Following Stem Cell Transplantation in Pediatric Patients.

Estimated Enrollment: 20
Study Start Date: October 2008
Estimated Study Completion Date: December 2010
Estimated Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Detailed Description:
All pediatric patients over the age of 4 years who are scheduled for a stem cell transplant will be approached to assess whether what the incidence of lactose intolerance is in the post transplant period and how quickly recovery occurs. A baseline lactose and lactulose breath test will be performed followed by repeat lactose breath tests starting 2 weeks after day 0 and repeated every fortnight for 10 weeks. Stool pH and reducing substances will be checked at the time of the breath tests to see if there is any correlation.

Ages Eligible for Study:   4 Years to 18 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • All patients planned to undergo a stem cell transplant.

Exclusion Criteria:

  • Refusal to participate
  • Unable to perform breath tests on request (generally under the age of 4 years.)
