Amaç: Atrial natriüretik peptid (ANP), kalp atriumunda sentezlenen ve plazmaya
salınan natriüretik, diüretik ve vazoaktif özellikli bir peptid hormondur. Migren fizyopatolojisinde ANP’nin rolünü araştıran çalışmalar artmıştır. Serebral korteksteki ANP artışının migrenin aura süreci boyunca vazokonstriksiyona bağlı iskemik hasar oluşmasına karşı bir savunma ve nöroprotektif mekanizma olduğu ileri sürülmüştür. Çalışmamızın amacı migrenli hastalarda başlangıçta, aura ve atak dönemlerinde serum ANP düzeylerini ölçmek ve bunun sağlıklı kontrol grubu ile karşılaştırmak, böylece serum ANP düzeyleri ile migren ağrısı özellikleri arasındaki ilişkiyi araştırmaktır.
Yöntem: Bu çalışmaya, Uluslararası Başağrısı Cemiyeti’nin 2004 sınıflamasına (ICHD 2) göre auralı migren tanısı konulan, yaşları 17-61 arası, 10’u kadın 5’i erkek toplam 15 auralı migren hastası ile eşit cins, yaş ve sayıda aurasız migren hastası alındı. Kontrol grubu aynı demografik verileri olan 15 sağlıklı gönüllüden oluşturuldu. Auralı migren grubundan başlangıçta, atak ve aura döneminde olmak üzere üç kere, aurasız migrenlilerde ise sadece başlangıçta ve atak dönemlerinde kanda ANP ölçümü yapıldı. Kontrol grubundan bir kere ANP için kan örneği alındı. ANP düzeyleri, Yedikule Göğüs Hastalıkları Hastanesi Biyokimya Laboratuvarı’nda “kardiyak reader” ile ölçüldü. İstatistiksel değerlendirmeler SPSS for Windows 15.0 paket programı ile yapıldı. T-testi, Kruskal Wallis testi, Spearman korelasyonu ve Mann Whitney-U testi kullanıldı.
Bulgular: Auralı migrenli grubun serum başlangıç ANP düzeyleri kontrol grubuna kıyasla istatistiksel olarak anlamlı şekilde düşük bulundu. Buna karşın aurasız migrenli grubun başlangıç ANP düzeyleri kontrol grubundan daha yüksekti. Migren alt grupları karşılaştırıldığında ise aurasız grubun ANP düzeylerinin auralı gruba kıyasla istatistiksel olarak anlamlı şekilde fazla olduğu görüldü.
Sonuç: Auralı migrenli hastalarda serum ANP düzeyinin aura ve atak döneminde başlangıç dönemine kıyasla ileri derecede arttığı, artışın aura döneminde belirginleştiği tespit edildi.
The Relationship Between Serum Atrial Natriuretic Peptide Levels and Pain in Migraine Patients
Background: Atrial natriuretic peptide (ANP) is a natriuretic, diuretic and vasoactive peptide hormone which synthesized by cardiac atria and released to plasma. Studies investigating the role of ANP in the physiopathology of migraine have risen. The increase of ANP in the cerebral cortex is suggested to be a defense and a neuroprotective mechanism that occurs against the ischemic damage that may arise from vasoconstriction forming during the aura stage of migraine. The aim of this study is to determine the serum ANP levels in patient with migraine during initial, aura and attack periods and compare with healthy controls and investigate the relationship between serum ANP level and migraine pain.
Methods: A total of 15 patients (10 female, 5 male; age range: 17-61), who were diagnosed with migraine with aura, and an equal number of age- and gender matched patients with migraine without aura according to the International Classification of Headache Disorders, 2nd edition (ICHD-2), and 15 healthy volunteers with the same demographic characteristics were randomly enrolled in the study. Blood samples were taken from patients with migraine with aura three times; at baseline, during an attack and during aura, whereas from patients with migraine without aura twice; at baseline and during an attack, and, once from healthy subjects. All blood samples were analyzed in the biochemistry laboratory, Yedikule Pulmonary Diseases Hospital using a cardiac reader and, ANP levels were calculated. Statistical analysis was performed using SPSS 15.0 for Windows. Data were analyzed using the student’s t-test, Kruskal-Wallis test, Spearman’s correlation coefficient and the Mann-Whitney U test.
Results: Initial serum ANP levels in patients with migraine with aura were statistically significantly lower than in controls. On the other hand, initial ANP levels in patients with migraine without aura were higher than in the control subjects. When the patients were compared, it was seen that the ANP levels in non-aura subjects were statistically significantly higher than in aura subjects.
Discussion: It is determined that in patients with migraine with aura, serum ANP level highly increases in the aura/attack stage compared to the initial stage, and this increase is marked in the aura stage.
