Amaç: Mevcut kanıtlar, proinflamatuar sitokinlerin, özellikle tümör nekrozis faktör alfanın (TNF-α) bipolar bozukluğun (BB) patofizyolojisinde önemli bir rol oynayabileceğini göstermektedir. Bu çalışmanın amacı, BB hastalarında farklı fazlarda ve sağlıklı kontrollerde TNF-α, çözünür tümör nekrozis faktör reseptör 1 ve çözünür tümör nekrozis faktör reseptör 2 (TNF-R1, sTNF-R2) seviyelerinin değişip değişmediğini araştırmaktır. Yöntem: Seksen üç BB tip I hasta (27 manik, 22 depresif ve 34 ötimik) ve psikiyatrik bozukluğu olmayan yirmi dokuz kontrol çalışmaya alındı. Serum TNF-α, sTNF-R1, sTNF-R2 seviyeleri, ELISA kiti kullanılarak ölçüldü. Bulgular: Gruplar arasında serum sTNF-R1 düzeylerinde istatistiksel olarak anlamlı farklılık bulundu. Depresyon veya mani hastalarında sTNF-R1 seviyeleri ötimik dönemdeki BB hastalardan ve kontrollerden daha yüksekti. Lojistik regresyon analizinde akut atak (mani ve depresyon) grubundaki BB hastaları ile belirtisiz grup (ötimik dönem ve kontrol grubu) arasında TNF-R1’in serum düzeyinde istatistiksel olarak anlamlı bir fark bulundu. Akut atak geçirme olasılığı, sTNF-R1’in serum seviyesinde her birim artış için üç kat yüksekti. Tüm gruplar arasında TNF-α ve sTNF-R2’nin ortalama serum değerlerinde istatistiksel olarak anlamlı farklılık bulunmadı. Sonuç: sTNF-R1 üretimi akut atak hastaları, kontrol grubu veya stabil BB hastaları arasında farklıydı. Bu çalışmanın sonuçları sTNF-R1’in BB için hastalık aktivitesini temsil eden bir durumsal belirteç olabileceğini desteklemektedir
Levels of TNF alpha, soluble TNF receptors (sTNF-R1, sTNF-R2) in bipolar disorder
Introduction: Current evidence suggests that pro-inflammatory cytokines, particularly tumor necrosis factor alpha (TNF-a) may play an important role in the pathophysiology of bipolar disorder (BD). Our study aims to compare BD patients and controls in terms of serum TNF-a, soluble tumor necrosis factor receptor 1 and soluble tumor necrosis factor receptor 2 (sTNF-R1, sTNF-R2) levels in different phases of BD. Methods: Eighty-three patients with BD type 1 (27 manic, 22 depressive and 34 euthymic) and twenty-nine healthy controls were included in the study. Serum levels of TNF-a, sTNF-R1, sTNF-R2 levels were evaluated with ELISA kit. Results: Levels of sTNF-R1 were showed a statistically significant difference between groups. Levels of sTNF-R1 were higher in depression or mania patients than euthymia patients and control subjects. A statistically significant difference in the serum level of sTNF-R1 between patients in acute episode (mania and depression) group and stabile (patients in euthymic episode and controls) group was found in logistic regression analysis. The probability of having acute episode increased threefold for each unit increase in serum level of sTNF-R1. There was no statistically significant difference between the mean serum values of TNF-a and sTNF-R2 between the groups. Conclusions: sTNF-R1 production was different between acute episode patients and controls or stable BD patients. The result of this study confirms that TNF-R1 may be a state marker representing disease activity for BD
