title: Tuberculosis before hematopoietic stem cell transplantation in patients with hematologic diseases: report of a single-center experience.
abstract: BACKGROUND
  Few reports discuss the optimal management of patients diagnosed with tuberculosis (TB) before scheduled stem cell transplantation (SCT), who then proceed with transplantation.
  
  
  METHODS
  We found 13 patients with TB before SCT (proven, n = 9; probable, n = 3; possible, n = 1) in the medical records of our institution.
  
  
  RESULTS
  Most of the patients had pulmonary TB (n = 8; disseminated, n = 2; extrapulmonary, n = 3). Eight of 9 patients with proven disease had SCT after at least 100 days of anti-tuberculous medication, ranging from 103 to 450 days. None of those patients suffered TB-related events after SCT. However, 1 patient with proven pulmonary TB who underwent SCT after only 40 days of anti-tuberculous therapy subsequently died of TB meningitis. Patients with possible and probable disease had their transplants after 6-176 days of anti-tuberculous medication, and all were alive at the time of analysis. The entire duration of anti-tuberculous medication was 12 months in most cases. With a follow-up duration ranging from 0.7 to 87.5 months, 4 patients died, but TB was the cause of death in only 1 case.
  
  
  CONCLUSIONS
  In conclusion, for proven cases of TB, SCT after >100 days of anti-tuberculous medication is probably feasible and safe, in terms of TB control, in patients with various hematologic diseases.
