Dirençli epilepsi hastalarında zonisamid deneyimi

Amaç: Parsiyel epilepsisi bulunan, > 16 yaş hastalarda zonisamidin güvenilir ve etkin bir antiepileptik ilaç olduğu yapılan kontrollü çalışmalarla gösterilmiştir. Ancak literatürde zonisamidin çocuklarda kullanımı, etkinliği ve güvenilirliği ile ilgili yeterli sayıda çalışma bulunmamaktadır. Gereç ve yöntem: Ocak 2010-Aralık 2010 tarihleri arasında, diğer anti-epileptik ilaçlara yanıt alınamayan ve zonisamid tedavisi başlanan 10 dirençli epilepsi olgusunun tedavi sonuçları değerlendirilmiştir. Zonisamid, 2 mg/kg/gün ve 2 dozda başlanarak, haftalık 1-2 mg/kg/gün doz artışı yapılmış ve maksimum 12 mg/kg/gün dozunda kullanılmıştır. Bulgular: On hastanın (5 kız, 5 erkek) ortalama yaşı 9,7 yıl (min 4,7-max 17)’dir. 2/10 olgu idiyopatik, 3/10 olgu kriptojenik, 5/10 olgu semptomatik epilepsi olarak sınıflandırılmıştır. Tedavi süresi ortalama 6,9 aydır. Olguların 6/10’u jeneralize, 4/10’u parsiyel epilepsi hastasıdır. Jeneralize ve parsiyel epilepsi gruplarında birer olguda ≥ %50 tedavi yanıtı görüldü. Parsiyel epilepsi olarak sınıflandırılan 1 olgunun ise nöbetsiz olduğu tespit edilmiştir. Zonisamid tedavisi süresince sadece 1 olguda geçici iştahsızlık ve kilo kaybı görüldüğü saptanmıştır. Sonuç olarak, antiepileptik ilaçlara yanıt alınamayan, özellikle parsiyel epilepsisi bulunan olgularda zonisamid tedavisinin etkili ve güvenli bir tedavi seçeneği olduğunu düşünmekle beraber daha çok olguyu kapsayan çalışmalarla desteklenmesi gerektiği kanaatindeyiz.

Zonisamide experience in patients with refractory epilepsy

Objeçtive: It have shown with controlled studies that, zonisamide is a safe and effective antiepileptic drug in > 16 years of age patients with partial epilepsy. However, there is not enough study on the efficacy and safety of the use zonisamide with children, in literature. Material and method: The treatment results of 10 cases with refractory epilepsy, not responded to the other anti-epileptic drugs and zonisamide therapy was initiated, between January 2010-December 2010, were evaluated, The starting dose of zonisamide was 2 mg / kg / day, dose has been increased weekly by 1-2 mg / kg / day and a maximum of 12 mg / kg / day was used. Results: Ten patients (5 boys, 5 girls), mean age was 9.7 years (min 4.7-max 17 years). 2/ 10 of the cases idiopathic, 3 / 10 of the cases cryptogenic and 5 / 10 of the cases were classified as symptomatic epilepsy. The mean duration of treatment was 6.9 months. 6 / 10 of the cases were generalized and 4 / 10 of the cases were partial epilepsy patient. In each generalized and partial epilepsy groups, ≥ 50% treatment response was seen in one patients. One case who had been classified as partial epilepsy was found as seizure free. In only 1 case, temporary loss of appetite and weight loss was seen during zonisamide therapy. As a result, we thought that zonisamide is effective and safe treatment option, particularly in patients with partial epilepsy who did not respond to other antiepileptic drugs, but more studies are needed to support.
