Trial Description


RATIONALE: Probiotics, such as Lactobacillus, may be effective in preventing infections in patients with suppressed immune systems.

PURPOSE: This phase I trial is studying the side effects and how well giving enteral nutrition, including Lactobacillus, works in preventing infections in patients undergoing donor stem cell transplant for hematologic cancer or myelodysplastic syndrome.

Further Study Information


  • To determine if patients who are treated with a probiotic-containing diet develop infection with one of the probiotic microorganisms while undergoing allogenic hematopoietic stem cell transplantation for a hematologic malignancy or myelodysplastic syndrome.

OUTLINE: Patients receive oral Lactobacillus rhamosus GG (Culturelle DS) once daily beginning when blood counts have recovered without filgrastim (G-CSF) or sargramostim (GM-CSF) support for 3 consecutive days and continuing for 1 year after transplantation.

Eligibility Criteria


  • Currently undergoing allogeneic stem cell transplantation from a related or unrelated donor for a hematologic malignancy or myelodysplastic syndrome
  • Hematopoietic engraftment as evidenced by recovery of the absolute neutrophil count > 1000/μL for > 3 days without filgrastim (G-CSF) support within 30 days of transplant


  • ECOG performance status 0-2
  • Serum creatinine ≤ 2.0
  • AST or ALT ≤ 3 times upper limit of normal (ULN)
  • Total bilirubin ≤ 2.0 times ULN
  • No clostridium difficile enterocolitis diagnosed during the transplant hospitalization in the peri-transplant period
  • Able to take medications by mouth
  • No evidence of graft-vs-host disease
  • No history of inflammatory bowel disease or other chronic diarrheal illness
  • No history of hypersensitivity to milk proteins


  • See Disease Characteristics
  • More than 3 months since prior use of probiotics supplements, excluding yogurt and cheeses with live cultures
  • No concurrent over-the-counter medications or herbal remedies
