Abstract

Background: Hematopoietic stem cell transplantation (HSCT) is considered as the last treatment option in many life-threatening diseases. The number of donated cells can affect transplantation success. This study attempted to investigate the relationship between the health-promoting lifestyle of allogeneic stem cell donors and the number of donated CD34+ and CD3+ cells.

Materials and Methods: The study was a descriptive correlational study in which 100 peripheral blood stem cells donors participated. A demographic form and health-promoting lifestyle profile-II questionnaire were distributed to participants, and then cell separation was started. Afterward, the results of CD34 + and CD3 + cell counts, as well as other clinical parameters of the participants, were recorded. The collected data were analyzed by descriptive and analytical statistical methods.

Results: The results showed that the mean total health-promoting lifestyle profile score for hematopoietic stem cell donors was 2.876±0.461. There was no significant relationship between the health- promoting lifestyle score and the number of CD34+, CD3+ cells and CD3+/CD34+ ratio. A positive and significant correlation was found between the weight of the donors and the number of CD34+ (P < 0.001) and CD3+ cells (P = 0.001). The number of CD34+ cells was significantly different between women and men (P = 0.009).

Conclusion: Lifestyle had no significant effect on the number of CD3+/CD34+ cells. Moreover, the number of CD34+ cells was significantly higher in men, so males should be preferentially recruited as donors for the HSCT procedure.
