Ketiyapin kullanımının yol açtığı epileptik nöbet: Olgu sunumu

Atatürk Eğitim ve Araştırma Hastanesi, İZMİR
Günümüzde atipik antipsikotikler birçok alanda yan etkilerinin daha az olması nedeniyle tipik antipsikotiklere göre
daha çok tercih edilmektedirler. Bu ilaçların ekstrapiramidal sistem bulgularına çok az ya da hiç yol açmıyor
olmaları önemli bir tercih nedenidir. Söz konusu durum hastaların yaşam kalitesini ve tedaviye uyumlarını belirgin
bir biçimde artırmaktadır. Ancak son yıllarda kullanıma giren bu ilaçlar şizofreni tedavisinde sağladıkları önemli
katkıların yanı sıra, daha önce tipik antipsikotiklerin kullanımı sırasında aynı ölçüde sorun oluşturmayan diyabetes
mellitus, kilo artışı, hiperlipidemi gibi metabolik yan etkileri de psikiyatri gündemine getirmişlerdir. Psikotropik
ilaçların bilinen bir başka özellikleri de elektroensefalografi (EEG) aktiviteleri üzerine olan etkileridir. Atipik
antipsikotiklerin EEG üzerine olan etkileri ile ilgili çalışmalar yetersiz olmakla birlikte, son zamanlarda bu konu
üzerinde daha çok çalışılmaya başlanmıştır. Bu çalışmaların sonucunda diğer tipik ve atipik antipsikotiklerle
yapılan az sayıda karşılaştırmalı çalışmada ketiyapinin diğerlerine göre belirgin olarak daha az EEG anormalliğine
yol açtığı gösterilmiştir. Bu çalışmaların yanı sıra ketiyapin kullanımı sırasında yeni başlangıçlı epileptik nöbeti
olan olgu bildirimleri de vardır. Bizim ‘genel tıbbi durumun (epilepsi) yol açtığı psikotik bozukluk’ olarak değerlendirdiğimiz
olgumuz, son dört yıldır hiç nöbeti olmayan ve koruyucu tedavi almasına karşın, ketiyapin kullanımı
sırasında ketiyapin ile tetiklenmiş epileptik nöbet ortaya çıkmış, ketiyapin kesildikten sonra ise nöbetleri yinelememiş
bir olgudur. Bu olguyu sunmaktaki amacımız ketiyapin kullanımı sonrasında gelişen epileptik nöbetlere ve
atipik antipsikotiklerin EEG üzerinde yol açabilecekleri anormallikleri araştıran çalışmaların kısıtlılığına dikkati
çekmek, bunun yanı sıra epilepsi hastalarında atipik antipsikotikleri kullanırken olası en düşük dozda ve yavaş
doz artırımları yapılarak kullanılmasını, her zaman nöbet geçirme potansiyellerinin varlığının göz önünde bulundurulmasını
vurgulamaktır.
Convulsion induced by quetiapine: a case report
Compared to typical antipsychotics, atypical antipsychotics are more frequently used because of their rare side
effects. One of the most important factors for the preference of atypical antipsychotics is that they cause very few
or no extrapyramidal system side effects at all. This results in significant increase in quality of life and treatment
compliance. Despite this, these newer antipsychotics may cause metabolic side effects such as diabetes mellitus,
weight gain and hyperlipidemia besides the important advantages they bring for the treatment of schizophrenia.
Psychotropic drugs also have effects on brain activity that can be observed on electroencephalography (EEG)
records. Research on the effects of atypical antipsychotics on EEG is inadequate but has gained acceleration in
recent [year]s. In these studies, it has been shown that quetiapine causes significantly less EEG abnormalities
compared to other typical and atypical antipsychotics. Quite the contrary, cases with epileptic seizures for the first
time during the use of quetiapine have been reported since then. In this paper we present a case with ‘psychotic disorder due to general medical condition (epilepsy)’. Our case did not have any epileptic seizures for the last four
[year]s when the seizures were induced with the use of quetiapine although she was taking antiepileptic treatment.
Seizures stopped after discontinuation of quetiapine. Our aim is to review studies about seizures that develop
during quetiapine treatment and to point out the lack of studies on atypical antipsychotics and EEG abnormalities.
We strongly suggest that atypical antipsychotics should be used with caution in minimal dosages and with slow
dose titration in patients with epilepsy. The probability of induction of seizures with antipsychotics should always
be kept in mind.
