Abstract

Aim: If there issuccessful mobilization following a conditioning regimen forstem cell transplantation, the in vivo purged stem cell products may be collected for a second transplantation. Materials and Methods: In this prospective study, peripheral blood CD34+ cells were quantified between 6 th day after stem cell infusion and 3 rd day after neutrophil engraftment in 20 patients using flow cytometry. Results: In the autologous peripheral blood stem cell transplantation (auto-PBSCT)group(n= 16), the CD34+ cell count was lowest during the first 10 days. The median CD34+ cell count began to increase at the 11 th day and the highest value was achieved at the 14 th day. We documented evidence of mobilization in only one patient (6.25%). Conclusion: Our results indicate thatthe rate of successful stem cell mobilization is very lowfollowing auto-PBSCT. In conclusion, collecting CD34+ stem cells following the first auto-PBSCT is not an effective method for tandem transplantation.

Özet

Amaç: Hazırlama rejimi ile yapılan kök hücre transplantasyonu sonarsı eğer başarılı kök hücre mobilizasyonu gerçekleşiyorsa, invivo olarak ayıklanmış bu kök hücreleri ikinci transplantasyon için kullanılabilir. Gereç ve Yöntemler: Bu prospektif çalışmada, periferik kan CD 34+ hücre düzeyleri kök hücre infüzyonu sonrası 6. Günden itibaren nötrofil yamanması sonrası 3. Güne kadar akım sitometri yöntemi ile ölçüldü. Çalışmaya toplam 20 nakil hastası dahil edildi. Sonuçlar: Otolog nakil yapılan grupta (n: 16), CD 34+ hücre sayıları 10. Günde en düşük düzeydeydi. Ortanca CD 34 + hücre sayısı 11. günde artmaya başlarken en yüksek değerine 14. günde ulaştı. Sadece bir hastada (%6.25) başarılı mobilizasyon bulgusuna rastlandı. Tartışma: Elde ettiğimiz bulgular gösterdi ki, otolog kök hücre nakli sonrası başarılı mobilizasyon oranları çok düşüktür. Sonuç olarak, birinci otolog nakil sonrası ardışık nakil için kök hücre toplama uygun bir yöntem değildir.
