Abstract

Özet

Araştırmamızda, hematopoetik kök hücre mobilizasyonu (HKHM) yapılan 65 yaş altı ve üstü hastalarda CD45/34 MFI (Ortalama Floresan Yoğunluğu) değerlerini karşılaştırmaya çalıştık.
Araştırma, 2015-2016 yılları arasında Anadolu Sağlık Merkezi Hastanesi Kemik İliği Transplantasyonu (KİT) Ünitesinde tespit edilen farklı kanser türlerine sahip 76 kişilik bir grubu kapsamaktadır. HKH'leri harekete geçirmek için katılımcılara 7-8 gün boyunca cilt altından günlük granülosit koloni uyarıcı faktör (G-CSF) (10 µg/kg/gün) uygulandı. Uygun periferik kan (PK) CD34+ seviyesinin hesaplanmasında hastaların WBC (Beyaz Kan Hücresi) sayıları dikkate alınmıştır. Araştırmamız 65 yaş üstü HKHM hastalarının bu yaşın altındakilere kıyasla istatistiksel olarak daha yüksek CD45/34 MFI değerlerine sahip olduğunu ortaya koymuştur. HKHM için yaş faktörü önemli olmakla birlikte, bulgularımıza göre 65 yaş ve üzeri hastalarda yaş HKHM için olumsuz bir mobilizasyon faktörü olarak görülmemektedir ve daha büyük çalışmalarla desteklenmelidir. Araştırmamız, HKHM uygulanan 65 yaş üstü hastaların genç hastalara kıyasla istatistiksel olarak daha yüksek CD45/34 MFI değerlerine sahip olduğunu ortaya koymuştur. KH üretiminde 65 yaş ve üzeri bireylerde gözlenen düşüş ve eşlik eden diğer hastalıkların potansiyeli göz önüne alındığında, sonuçlarımız yaşlı hastalar için umut vaat etmektedir. Bununla birlikte, bu bulguların çok merkezli çalışmalarla daha geniş bir hasta popülasyonuyla doğrulanması ve gözlem altındaki hastalarda diğer müteakip hastalıkların varlığının da dikkate alınması önemlidir.

Abstract

Abstract

In our research, we attempted to compare CD45/34 MFI (Mean Fluorescent Intensity) in patients younger and over 65 years of age with hematopoietic stem cell mobilization (HSCM).
The research involved a group of 76 individuals who had different types of cancer and were identified at the Bone Marrow Transplantation (BMT) Unit of Anadolu Medical Center Hospital from 2015 to 2016. To mobilize HSCs, participants were administered daily granulocyte colony-stimulating factor (G-CSF) (10 µg/kg/day) under the skin for 7-8 days. Calculating the appropriate level of peripheral blood (PB) CD34+ took into account the patients' WBC (White Blood Cell) counts. Our research revealed that HSCM patients above 65 had statistically greater CD45/34 MFI values than those under that age. Although the age factor for HSCM is important, according to our findings, age is not seen as a negative mobilization factor for HSCM in patients aged 65 and over, and should be supported by larger studies. Our research revealed that patients over 65 who underwent HSCM had statistically greater CD45/34 MFI values than younger patients. Given the decline in SC production observed in individuals aged 65 and above, along with the potential for other accompanying diseases, our results hold promise for elderly patients. However, it is important to validate these findings through multicenter studies with a larger patient population, while also taking into account the presence of other subsequent diseases in the patients under observation.
