Abstract

Objectives: S-100B a protein prevalent in the central nervous system is a peripheral biomarker for blood-brain barrier disruption and neuronal damage. The objective of the study was to investigate the S-100B levels in patients with subacute sclerosing panencephalitis. Materials and methods: A group of 40 patients with SSPE and 40 healthy controls were recruited. Serum S-100B protein concentrations were measured using a commercially available electrochemiluminescence immunoassay (ECLIA) kit, as supplied and according to the manufacturer's standards. Results: Median S-100B levels were 0.095 ± 0.017 μg/L in patients with SSPE and 0.097±0.019 μg/L in the control group. This difference was not statistically significant (p>0.05). The patient group was further subdivided into two subgroups according to the presence or absence of brain atrophy. The S-100B levels were 0.096 ± 0.018 μg/L in the subgroup with atrophy and 0.094±0.014 μg/L in the subgroup without atrophy. This difference was also not statistically significant (p>0.05). Conclusions: Our results suggest that serum S-100B is not a reliable marker for neuronal damage in SSPE.

Abstract

Amaç: S-100B santral sinir sisteminde yaygın olarak bulunan, kan beyin bariyeri yıkımında ve nöronal hasarda periferik belirteç olarak kullanılan bir proteindir. Bu çalışmanın amacı, Subakut sklerozan panensefalitli hastalarda S-100B düzeylerini araştırmaktır. Gereç ve yöntem: Çalışmada, SSPE\' li 40 hasta ile 40 sağlıklı kontrol grubu alındı. Serum S-100B protein konsantrasyonları elektrokemiluminesan immunoassay (ECLIA) yöntemi ile üretici standartlarına göre ölçüldü. Bulgular: Ortalama S-100B seviyeleri SSPE\'li hasta grubunda 0.095 ± 0.017 μg/L, kontrol grubunda ise 0.097 ± 0.019 μg/L bulundu. Aralarında istatistiksel olarak anlamlı farklılık bulunmadı (p>0.05). Hasta grubu beyin atrofisinin varlığına göre iki altgruba ayrıldı. S-100B seviyeleri beyin atrofisi olan grupta 0.096±0.018 μg/L, atrofisi olmayan grupta ise 0.094±0.014 μg/L idi. Bu farklılık istatistiksel olarak anlamlı değildi (p>0.05). Sonuç: Bizim sonuçlarımız, S-100B\'nin SSPE\' de nöronal hasarda güvenilir bir belirteç olmadığını göstermektedir.
