Abstract

Introduction: The overproduction of the efflux transporters in the bloodbrainbarrier is considered to play a role in the development of drugresistance in mesial temporal lobe epilepsy (MTLE) patients. The aim ofthe present study was to investigate the relationship of clinical features ofpatients with MTLE accompanied by hippocampal sclerosis (HS) and thep-glycoprotein (p-gp) expression and neuronal loss in the hippocampus.Methods: This study included a total of 33 patients who underwentselective amygdala-hippocampectomy operation. A detailed medicalhistory of each patient, including age, side of HS, sex, age of habitualseizure onset, duration of habitual seizures, type and age of initialprecipitating injury, presence and duration of latent period, presenceand duration of silent period, monthly seizure frequency within 1 yearprior to operation, mean age at the time of operation was evaluatedretrospectively.Results: The p-gp expression was significantly higher in the patient groupwith a seizure frequency of more than 15 days per month and a diseaseduration of more than 20 years. There was no significant differencebetween the p-gp expression and the clinical features of the MTLE-HSpatients.Conclusion: These results suggest that p-gp expression is affected bydisease duration and seizure frequency rather than a patient’s clinicaland pathological properties. In patients with HS-MTLE, potential use ofthe p-gp inhibitors as additional therapy and developing novel drugs notcarried by multidrug carriers expressed in blood-brain barrier should beregarded as the new treatment targets.

Özet

Amaç: Kan beyin bariyerinde “efflux transporter”ların aşırı üretiminin mezial temporal lob epilepsili (MTLE) hastalarda ilaç tedavisine direnç gelişiminde rol oynayabileceği düşünülmektedir. Bu çalışmada, hipokampal sklerozun (HS) eşlik ettiği MTLE’li hastaların klinik özellikleri ile hipokampusta p-glikoprotein (p-gp) ekspresyonu ve nöronal kayıp arasındaki ilişkiyi araştırmak amaçlanmaktadır. Yöntem: Selektif amigdala-hipokampektomi operasyonu geçirmiş 33 hasta çalışmaya alındı. Her hastanın yaş, HS’nin bulunduğu taraf, cinsiyet, habitüel nöbetlerin başladığı yaş, habitüel nöbetlerin süresi, IPI’nin tipi ve geliştiği yaş, “latent period” varlığı ve süresi, “silent period” varlığı ve süresi, operasyon öncesindeki bir yıl içinde aylık ortalama nöbet frekansı ve operasyonun yapıldığı yaşın ortalaması içeren ayrıntılı klinik hikâyesi retrospektif olarak incelendi. Bulgular: P-gp ekspresyonu ayda 15 günden fazla nöbet sıklığı ve 20 yıldan fazla hastalık süresi olan hasta grubunda anlamlı olarak daha fazla idi. MTLE-HS hastalarının klinik özellikleri ve p-gp ekspresyonu arasında anlamlı bir fark yoktu. Sonuç: Bu bulgular p-gp ekspresyonunun hastanın klinik ve patolojik özelliklerinden çok hastalığın süresi ve nöbet sıklığından etkilendiğini düşündürmektedir. HS-MTLE hastalarında, inhibitörlerin ek tedavi olarak olası kullanımı ve kan beyin bariyerinde eksprese edilen “multi-drug” taşıyıcıları ile taşınmayan ilaçların geliştirilmesi yeni tedavi hedefleri olarak değerlendirilmelidir.
