Serum levels of fibroblast growth factor in patients with intracerebral hemorrhage

Abstract

Objectives: Intracerebral hemorrhage (ICH) is one of the most mortal subtypes of stroke. Due to the angiogenic, neurotropic, and vessel-dilating properties of basic fibroblast growth factor (bFGF) in the brain, role of bFGF has been investigated in a number of neurological disorders. So far, there is only study about serum bFGF levels in patients with ICH. The first aim of the present research is to investigate whether increased serum bFGF in patients with ICH. Also, second aim was to study the association between serum levels of bFGF and clinical status in patients with ICH. Materials and methods: We measured the serum levels of bFGF in 30 patients with ICH during acute period. Age and sex matched healthy subjects (n=30) were included in controls. Serum bFGF levels were measured using an enzyme-linked immunosorbent assay method. Results: The patients with intracerebral hemorrhage had higher serum levels of bFGF when compared with the healthy controls (12.89±3.23 ng/ml, 5.28±1.75 ng/ml; p=0.001). No statistically significant difference was determined between bFGF levels of the patients who died as compared to the patients who lived (13.49±4.13 ng/ml; 12.43±3.43 ng/ml, p>0.05). No statistically significant difference was found between bFGF levels of the patients with intraventricular hemorrhage as compared to the patients without intraventricular hemorrhage (13.54±3.92 ng/ml; 12.24±2.29 ng/ml, p>0.05). There was no correlation between serum bFGF, hematoma volume, Gloskow coma scale, and National Institutes of Health stroke scale (p>0.05). Conclusion: The increased bFGF level may be one of the mechanisms that lead to angiogenesis and neuroprotection after ICH in human.

İntraserebral kanamalı hastalarda serum fibroblast büyüme faktörü düzeyleri

Öz

Amaç: İntraserebral kanama inmenin en ölümcül alt tiplerinden birisidir. Beyinde bazik fibroblast büyüme faktörünün (bFGF) anjiogenik, nörotropik ve damar genişletici özellikleri nedeniyle çok sayıda nörolojik hastalıkta bFGF\'nin rolü araştırılmıştır. Şu ana kadar intraserebral kanamalı hastaların serumunda bFGF\'yi araştıran sadece bir çalışma vardır. Bu çalışmanın birinci amacı intraserebral kanamalı hastaların serumunda bFGF artışı olup olmadığını araştırmaktır. Ayrıca ikinci amacımız intraserebral kanamalı hastalarda serum bFGF ile klinik durumla ilişkisini araştırmaktı. Gereç ve yöntem: Akut dönemde 30 intraserebral kanamalı hastada serum bFGF seviyelerini ölçtük. Yaş ve cinsiyet yönünden benzer 30 sağlıklı kişi kontrol grubuna dahil edildi. ELİSA yöntemiyle serumda bFGF ölçüldü. Bulgular: Serum bFGF seviyeleri intraserebral kanamalı hastalarda (12.89±3.23 ng/ml) kontrol grubuna (5.28±1.75 ng/ml) göre istatistiksel olarak anlamlı düzeyde yüksek bulundu (p=0.001). İntraserebral kanamalı (İSK) hastalarda ölenlerle (n=13) sağ kalanların (n=17) serum bFGF düzeyi benzerdi (13.49±4.13 ng/ml; 12.43±3.43 ng/ml, p>0.05). Ventriküle açılım gösteren (n=15) İSK\'li hastalarla ventriküle açılım göstermeyen (n=15) hastaların bFGF düzeyi arasında fark bulunmadı (13.54±3.92 ng/ml; 12.24±2.29 ng/ml, p>0.05). İntraserebral kanamalı hastalarda serum bFGF düzeyi ile hematom hacmi, Glaskow koma skalası ve uluslar arası inme skalası arasında ilişki bulunmadı (p>0.05). Sonuç: İnsanlarda intraserebral kanamadan sonra artmış bFGF nöron koruyucu ve anjiogeneze neden olan mekanizmalardan birisi olabilir.
