  Purpose

In the transplant community, there is debate regarding the most appropriate food services for stem cell transplant patients. Recommendations regarding the use of low bacterial diets have been based on theoretical concepts of reducing the risk of contracting infections from pathogens found in food sources rather than clinical trials. The evidence for the use of a neutropenic diet is weak. To date, there have been little to no randomized controlled studies addressing the question whether a neutropenic diet in addition to prophylactic antibiotics is necessary as infection prevention in myeloablative stem cell transplant patients. For this reason, our research is aimed at providing data to substantiate the use of neutropenic diets in preventing infections in recipients of myeloablative stem cell transplants.

Endpoint Classification: Safety Study
Intervention Model: Parallel Assignment

Primary Purpose: Prevention
Official Title: A Randomized Pilot Study Comparing Infection Rates in Myeloablative Allogeneic Stem Cell Transplant Patients Receiving a Non-Neutropenic Diet or a Neutropenic Diet

Further study details as provided by Duke University:

Primary Outcome Measures:
  • Incidence of Bacteremia [ Time Frame: Duration of hospitalization or neutropenia, an expected average of 5 weeks. ] [ Designated as safety issue: Yes ]
    Participants will be followed for the duration of hospital stay or until neutropenic, an expected average of 5 weeks. The time frame will be measured from the date of randomization until the date of discharge from the inpatient unit of the hospital or until they are assessed to be neutropenic, whichever came first, assessed up to 8 weeks.


Secondary Outcome Measures:
  • Assess nutritional status using PG-SGA [ Time Frame: Duration of hospitalization or neutropenia, an expected average of 5 weeks. ] [ Designated as safety issue: Yes ]
    The participants will be followed for the duration of hospital stay or until neutropenic, an expected average of 5 weeks. The time frame will measured from the date of randomization until the date of discharge from the inpatient unit of the hospital or until they are assessed to be neutropenic, whichever came first, assessed up to 8 weeks. The nutritional status will be assessed by the Scored Patient-Generated Subjective Global Assessment (PG-SGA) platform.

Arms Assigned Interventions
No Intervention: Neutropenic Diet
This arm is the control and subjects will receive the standard of care neutropenic diet.
Experimental: Non-neutropenic Diet
This arm is interventional and subjects will receive a non-neutropenic diet without restriction.
Other: Non-neutropenic Diet
Non-neutropenic diet is without restriction.

Detailed Description:

In the proposed pilot study, a randomized design will be used to address the primary and secondary aims. Subjects will be randomized to either the experimental group receiving a non-neutropenic diet without restriction, or to the control group receiving the standard neutropenic diet. While randomization will occur prior to, or on the day of their inpatient admission and the subjects will begin study procedures upon admission to the Adult Stem Cell Transplant Inpatient Unit at Duke University Medical Center.

The diet will continue until 1) the subject is no longer neutropenic, and/or 2) discharged from the inpatient unit to continue their care in the Adult Stem Cell Transplant Outpatient Clinic. By limiting the study to the time of care on the inpatient unit, we will minimize the opportunity for deviation from the assigned diet. Absence of neutropenia will be defined as an absolute neutrophil count of greater than 500/uL (manual differential) and a total white blood cell count of 1000/uL for three consecutive days.

All subjects enrolled will follow the standard prophylactic antibiotic regimen. Other supportive care will also be consistent in the two groups.
