Çocukluk çağı akut lenfoblastik lösemilerde serum Fas ve Fas Ligand düzeyleri

Year 2019, Volume: 44 Issue: 4, 1400 - 1404, 29.12.2019

Abstract

Amaç: Bu çalışmada, çocukluk çağı akut lenfoblastik lösemilerinde (ALL), apoptozis mekanizmasının anlaşılmasında rol oynayan hücre membran reseptörlerinden serum Fas ve Fas Ligand düzeyinin araştırılması amaçlanmıştır.

Gereç ve Yöntem: Çocukluk çağı akut lenfoblastik lösemi tanısı (1-18 yaş) almış 29 hastada tanı anında periferik kandan elde edilen serum Fas ve Fas Ligand düzeyleri ELISA yöntemi ile çalışıldı. Yirmiyedi çocuktan oluşan kontrol grubunun yaş dağılımı 1-15 yıl arasındaydı. 

Bulgular: ALL‟li hastalarda serum Fas düzeyi ortanca 63 pg/mL (15-690 pg/mL) kontrol grubunda ortalama serum Fas düzeyi ortanca 37 pg/mL (8-67 pg/mL) saptandı. ALL‟li hastalarda serum Fas Ligand düzeyi ortanca 0,18 ng/mL (0-2,1 ng/mL), kontrol grubunda ise ortanca 0,1 ng/mL (0-4 ng/mL) saptandı. Akut lenfoblastik lösemi tanılı hastalar ile, kontrol grubu arasında ortalama serum Fas düzeyleri açısından istatistiksel olarak anlamlı fark varken, Fas Ligand düzeyleri arasında fark saptanmadı. Akut Lenfoblastik Lösemili hastalar immunfenotiplemeye göre serum Fas düzeyi karşılaştırıldığında T-ALL hastalarında B-ALL’li hastalara göre istatistiksel olarak anlamlı fark bulundu. Relaps olan hastalarda remisyondaki hastalara göre Fas düzeyleri anlamlı olarak yüksek saptandı. 

Sonuç: Bu bulgular sonucunda serum Fas düzeylerinin ALL hastalarda prognostik faktör olarak değerlendirilebileceği düşünüldü.

Serum Fas and Fas Ligand levels in childhood acute lymphoblastic leukemias

Year 2019, Volume: 44 Issue: 4, 1400 - 1404, 29.12.2019

Abstract

Purpose: The aim of this study was to investigate the Fas and Fas Ligand levels of cell membrane receptors that play a role in understanding the mechanism of apoptosis in childhood acute lymphoblastic leukemia (ALL). 

Materials and Methods: We investigated serum Fas and Fas Ligand levels by using ELISA method in childhood acute leukemias. Twenty-nine cases with acute lymphoblastic leukemia and twenty-seven healthy children included the study. We investigated serum Fas and Fas Ligand levels at the time of diagnosis from peripheral blood samples. 

Results: Serum Fas levels of patients were median 63 pg/mL (min 15- max 690 pg/mL) and in the control group were median 37 pg/mL (min 8- max 67 pg/mL). Fas Ligand levels of patients were median 0.18 ng/mL (min 0- max 2.1 ng/mL) and in the control group median 0.1 ng/mL (min 0- max 4 ng/mL). The comparison of the mean values of Fas levels in acute leukemia patients groups and control group have shown important difference as statistically, but Fas Ligand levels were similar. Fas levels in T-ALL patients according to immunophenotypes were statistically higher than B-ALL . The Fas levels of patients who had relapsed were statistically higher than patients in remission. 

Conclusion: Serum Fas levels could be a useful prognostic marker in ALL patients follow up.
