Abstract

We report two male cases (4- and 5-years-old) of intrathecal methotrexate overdose. The two boys with acute lymphoblastic leukemia were to receive intrathecal injection of methotrexate. Instead of the prescribed 12 mg, they both received a dose of 120 mg. The initial cerebrospinal fluid samples showed methotrexate concentration of 2.24x10-2M in case 1 and 1.32x10-2M in case 2. The cases were success- fully treated with cerebrospinal fluid (CSF) exchange and intravenous folinic acid rescue. The favor- able outcome in our cases suggests that CSF exchange is safe and that folinic acid rescue may be adequate to prevent sequelae in patients subjected to intrathecal MTX overdoses up to 120 mg. We propose CSF exchange and intravenous folinic acid as the mainstay of treatment. In addition to the staff ’s failure to check the drug label carefully, the marked resemblance of the two dose preparations of MTX may have been contributory.

Özet

İntratekal (IT) metotreksat uygulaması, merkezi sinir sistemi lösemisinin önlenmesi ve tedavisinde yaygın olarak kullanılmaktadır. Metotreksatın yüksek dozda veya uzun süreli uygulamaları ciddi nör- otoksisiteye yol açabilir. Burada, hatalı olarak yüksek dozda intratekal metotreksat verilen iki olgu sunulmaktadır. Akut lenfoblastik lösemi tanısıyla izlenen 4 ve 5 yaşlarındaki iki erkek olguya, reçete edilen 12 mg yerine yanlışlıkla 120 mg dozunda intratekal metotreksat uygulandı. Uygulama sonrası başlangıç beyin omurilik sıvısı metotreksat düzeyleri sırasıyla 2.24x10-2M ve 1.32x10-2M idi. Olgular beyin omurilik sıvısı değişimi ve intravenöz folinik asit desteği ile başarılı bir şekilde tedavi edildiler. Takiplerinde klinik gidişin iyi olması, 120 mg’a kadar yüksek doz intratekal metotreksat uygulanmış hastalarda, beyin omurilik sıvısı değişimi ve folinik asit kurtarma tedavisinin sekelleri önleme açısından yeterli olabileceğini göstermektedir. Bu hatalı uygulamaya asistanların ilaç dozlarını kontrol etmedeki hatalarının ve farklı dozlardaki metotreksat preparatlarının benzer kutularda üretilmesinin yol açtığı düşünülmüştür.
