Gaucher Hastalığında Tanı ve Tedavi İzleminde Biyobelirteçlerin Değerlendirilmesi

Öz

Amaç: Bu çalışmanın temel amacı düzenli tedavinin anahtar hastalık belirteci Lyso-Gb1 üzerindeki etkisini araştırmaktır. Ayrıca bu araştırma, hasta grubunda splenektominin Lyso-Gb1 konsantrasyonları üzerindeki etkisini değerlendirmeyi amaçlamaktadır. Gereç ve Yöntem: Gaucher Hastalığı (GH) tanısı alan 37 hasta tedavi durumuna göre üç gruba ayrıldı: Tedavilerini tutarlı bir şekilde takip eden düzenli tedavi grubunda 28; düzensiz tedavi grubunda 6 ve henüz tedavi almayan grupta 3 hasta mevcuttu. GH olmayan 33 sağlıklı bireyden oluşan bir kontrol grubu da dahil edildi. Tedavi rejimi olarak enzim replasman tedavisi kullanıldı. Lyso-Gb1 seviyelerinin analizi, ölçümde yüksek hassasiyet sağlayan tandem kütle spektrometresi ile birleştirilmiş sıvı kromatografisi kullanılarak gerçekleştirildi. Bulgular: Lyso-Gb1 seviyeleri Gaucher hastalarında sağlıklı kontrol grubuyla karşılaştırıldığında anlamlı derecede yüksekti (p<0.05), bu da bunun spesifik bir biyobelirteç olma potansiyelini doğruluyor. Tedavi, Lyso-Gb1 seviyelerinde bir azalma ile ilişkilendirildi (p<0.05). Tedavi edilen Tip 1 ve Tip 3 GH arasında Lyso-Gb1 düzeyleri açısından anlamlı bir fark gözlenmedi (p>0,05). Özellikle splenektomi yapılan hastalarda, yapılmayanlara göre anlamlı derecede daha yüksek Lyso-Gb1 seviyeleri sergilendi (p<0.05). Sonuç: Bulgularımız Lyso-Gb1'in GH için spesifik bir biyobelirteç olarak kullanımını desteklemektedir. Tedavi edilen grupta tedavi öncesi Lyso-Gb1 seviyeleri bilinmemekle birlikte, sonuçlarımız Lyso-Gb1'in GD'de hastalığın ilerlemesini ve tedavi etkinliğini izlemedeki rolünü daha fazla aydınlatmak için daha büyük, boylamsal çalışmalara olan ihtiyacın altını çiziyor.

Abstract

Aim/Objective: The primary goal of this study is to explore the impact of consistent treatment on key disease marker, Lyso-Gb1. Additionally, this research aims to evaluate the influence of splenectomy on Lyso-gb1 concentrations within the patient group. Materials and Methods: 37 patients diagnosed with GD were categorized based on treatment compliance into three groups: 28 in the regular treatment group, who consistently followed their treatment; 6 in the irregular treatment group, with inconsistent treatment adherence; and 3 in the untreated group. A control group of 33 healthy individuals without GD was also included. Enzyme replacement therapy was utilized as the treatment regimen. The analysis of Lyso-Gb1 levels was performed using liquid chromatography coupled with tandem mass spectrometry, ensuring high precision in measurement. Results: Lyso-Gb1 levels were significantly higher in GD patients compared to the healthy control group (p<0.05), affirming its potential as a specific biomarker. Treatment was associated with a reduction in Lyso-Gb1 levels (p<0.05). No significant difference in Lyso-Gb1 levels was observed between treated patients with Type 1 and Type 3 GD (p>0.05). Notably, patients who underwent splenectomy exhibited significantly higher Lyso-Gb1 levels than those who did not (p<0.05). Conclusion: Our findings support the utility of Lyso-Gb1 as a specific biomarker for GD. While pre-treatment Lyso-Gb1 levels in the treated group remain unknown, our results underscore the need for larger, longitudinal studies to further elucidate Lyso-Gb1's role in monitoring disease progression and treatment efficacy in GD.
