Abstract

Objectives: Zonisamide (ZNS) is a newer generation antiepileptic drug used against partial and generalized seizures. The aim of this study was to investigate the safety and efficacy of ZNS in refractory epilepsy patients under clinical follow-up in our center. Methods: A total of 45 patients were found eligible. Six patients observed for less than six months were excluded. Age, gender, seizure types, neurological examination, magnetic resonance imaging, EEG features, number of concomitant antiepileptic drugs, seizure reduction, and adverse effects were noted. Results: The remaining 39 patients, with a mean age of 34.3±9.3 years, were evaluated. The seizure types were complex partial seizure (CPS) and generalized tonic-clonic seizure (GTCS) in 74.4%, GTCS in 10.3%, CPS in 7.7%, GTCS and myoclonia in 5.2%, and GTCS, absence and myoclonia in 2.6% patients. Nineteen of the 39 patients stopped treatment due to aggrevated seizures, unchanged seizure frequency, or side effects. A seizure frequency reduction of 25% was noted in 1, 50% in 5, and 75% in 7 patients. Three patients became seizure-free. Shortening of the seizure period was noted in four patients. Good clinical response was achieved in between 7-80 months’ long treatment with 100–400 mg/day doses. Conclusion: ZNS is used as a safe, tolerable, and effective add-on alternative therapy for refractory epilepsy patients in our center.

Özet

Amaç: Zonisamid (ZNS), parsiyel ve jeneralize nöbetleri olan epilepsi hastalarının tedavisinde kullanılan yeni nesil bir antiepileptik ajandır. Bu çalışmanın amacı hastanemiz takipli dirençli epilepsi hastalarının tedavisinde ZNS’nin güvenilirliğini ve etkinliğini araştırmaktır. Gereç ve Yöntem: Çalışmaya, ZNS tedavisi altında olan, 45 dirençli epilepsi hastası dahil edildi. Altı aydan kısa süre ZNS tedavisi altında olan hastalar dışlandı. Yaş, cinsiyet, nöbet tipleri, muayene bulguları, manyetik rezonans görüntüleme, elektroensefalografi bulguları, eş zamanlı kullanılan ZNS dışı antiepileptik ilaç sayısı, nöbet sıklığında azalma ve ilaç yan etkileri kaydedildi. Bulgular: Yaşları ortalama 34.3±9.3 yıl olan 39 hasta değerlendirildi. Hastaların %74.4’ünde kompleks parsiyel nöbet (KPN) ve jeneralize tonik klonik nöbet (JTKN), %10.3’ünde yalnızca JTKN, %7.7’sinde yalnızca KPN, %5.2’sinde JTKN ve miyokloni, %2.6’sında ise JTKN, absans ve miyokloni mevcuttu. İzlemde 39 hastanın 19’unda, ilaç yan etkisi, nöbet sıklığında değişme olmaması ya da artış olması nedeniyle tedavinin sonlandırıldığı görüldü. Yirmi hasta tedaviye yanıt vermişti. Nöbet sıklığı; bir hastada %25; beş hastada %50; yedi hastada %75 oranında azalmıştı. Üç hastada nöbetsizlik sağlanmıştı. Dört hastada ise nöbet sıklığında bir değişiklik olmamasına rağmen nöbet süresi kısalmıştı. Tedaviye yanıtlı hastalar 7–80 ay arasında değişen sürelerde 100–400 mg/gün değişen dozlarda ZNS kullanmaktaydı. Sonuç: Zonisamid, merkezimizde dirençli epilepsi hastalarının ekleme tedavisinde güvenli, tolere edilebilir ve etkin bir seçenek olmuştur
