    Objective: Epilepsy is a neurological disease characterized by recurrent seizures. The underlying pathophysiological mechanisms in epilepsy are not fully known. Our aim is to investigate the relationship between serum adipocytokine and interleukin (IL)-18 levels in epilepsy patients receiving and not receiving antiepileptic therapy. Method: Our study was established as three groups. I: Epilepsy patients receiving antiepileptic therapy (n=30), II: Newly diagnosed epilepsy patients (n=30) and III: Control group (n=30). Serum adipocytokine and IL-18 levels were measured by enzyme-linked immunoassorbent assay method. Results: It was determined that serum adipocytokine and IL-18 levels were increased in epilepsy patients who received topiramate treatment and did not receive antiepileptic therapy compared to the control group. Serum glucose, total protein, cholesterol and albumin concentrations of patients who received antiepileptic treatment were decreased compared to the control group (p0.05). It was found that the body mass index (BMI) ratio of epilepsy patients who received antiepileptic treatment decreased and was significant compared to the control group and the group that did not receive treatment (p

    Increased visinin-like protein-1, YKL-40, lipocalin-2, and IL-23 levels in patients with migraine
    (TAYLOR & FRANCIS LTD, 2022) Dündar, Ahmet; Cafer, Vugar; Aslanhan, Hamza; Özdemir, Hasan Hüseyin; Yılmaz , Ahmet; Çevik, Mehmet Uğur
    Background: Migraine is a type of primary headache caused by changes in the trigeminal system and has been reported to be associated with neurovascular inflammation of cerebral and extracerebral vessels. Objective: It is known that inflammation is an important process in the pathogenesis of migraine. It has been shown that the molecules of visinin-like protein 1 (Vilip-1), YKL-40, lipocalin-2 and interleukin (IL)-23 play a role in the inflammatory process. Our aim is to investigate the role of this molecule in the metabolic pathway of migraine disease. Methods: Fifty migraine patients with and without aura in the interictal period were included in the study. Vilip-1, YKL-40, lipocalin-2, and IL-23 levels were measured by ELISA method. Results: Serum vilip-1, YKL-40, lipocalin-2, and IL-23 levels were found to be significantly higher in migraine patients compared to the control group. We found that this molecule increased significantly in migraine subgroups compared to the control group (p < 0.001). A positive significant correlation was found between vilip-1 level and YKL-40 and lipocalin-2 levels in migraine patients. In addition, a positive correlation was observed between visual analogue scale score, number of days with pain and vilip-1 level (p < 0.01). The results of our study showed that activation of inflammatory mediators may play a role in the pathogenesis of migraine disease. In addition, our study is valuable in that inflammatory molecules are high in the interictal period and these biomarkers have never been analyzed in migraine patients. However, we still believe that larger studies are needed to explain the role of vilip-1, YKL-40, lipocalin-2, and IL-23 in the molecular mechanism of migraine disease.

    Investigation of serum vaspin, visfatin, chemerin and IL-18 levels in migraine patients
    (SciELO, 2021) Donder, Ahmet; Cafer, Vugar; Yilmaz, Ahmet; Aslanhan, Hamza; Arikanoglu, Adalet
    Background: Migraines are headaches caused by changes in the trigeminovascular metabolic pathway. Migraine headache attacks are associated with neurovascular inflammation, but their pathophysiological mechanisms have not been fully explained. Objective: To investigate the relationship between serum vaspin, visfatin, chemerin and interleukin-18 (IL-18) levels and the frequency of attacks in migraine headache. Methods: Three groups were established: migraine with aura (n = 50), migraine without aura (n = 50) and control group (n = 50). The migraine diagnosis was made in accordance with the International Classification of Headache Disorders-III beta diagnostic criteria. The analyses on serum vaspin, visfatin, chemerin and IL-18 levels were performed using the enzyme-linked immunosorbent assay method. Results: The serum vaspin, visfatin, chemerin and IL-18 levels were found to be significantly higher in the migraine patients than in the control group (p < 0.01). No statistically signi?cant differences in serum vaspin, visfatin, chemerin and IL-18 levels were found among the migraine patients during attacks or in the interictal period (p>0.05). The serum visfatin and chemerin levels of the migraine patients were positively correlated with their serum IL-18 levels (p < 0.01), while their serum chemerin and visfatin levels were positively correlated with their serum vaspin levels (p < 0.05). Conclusions: This study showed that these biomarkers may be related to migraine pathogenesis. Nonetheless, we believe that more comprehensive studies are needed in order to further understand the role of vaspin, visfatin, chemerin and IL-18 levels in the pathophysiology of migraine headaches.
