Amaç: Antioksidan savunma sistemleri, şizofreni etyopatogenezinde araştırılması gereken önemli bir alanı oluşturmaktadırlar. Erişkinlerde bugüne kadar yapılmış çalışmaların sonuçlarının tartışılmaya değer olması, çocuklarda da antioksidan savunma sistemleri üzerine araştırma yapılması düşüncesini uyandırmaktadır.

Yöntem: Bu çalışmamızda DSM-IV tanı ölçütlerine göre yaygın gelişimsel bozukluk (YGB) tanısı konan 3-12 yaşları arasında 35 çocuğu ve kontrol grubu olarak DSM-IV tanı ölçütlerine göre dikkat eksikliği hiperaktivite bozukluğu (DEHB) tanısı konan aynı yaş grubunda 60 çocuğu antioksidan savunma sistemleri açısından karşılaştırdık.

Bulgular: Çalışmamızda önemli serbest radikal temizleyicisi ve antioksidan savunma sisteminin nonenzimatik elemanlarından glutatyon (GSH) ortalama değerinin YGB olgularında kontrol grubuna göre daha yüksek olduğu ancak, aradaki farkın istatistiksel olarak anlamlı olmadığı tespit edilmiştir. Malondialdehid (MDA) seviyeleri karşılaştırıldığında iki grup arasında anlamlı bir fark bulunmamıştır.

Tartışma: Bu sonuç erişkin şizofreni hastalarıyla yapılan ve serum MDA düzeyleri kontrol grubundan yüksek bulunan çoğu çalışmanın sonuçlarıyla çelişmektedir. Bu konuda daha büyük bir popülasyon üzerinde yapılmış araştırmalara ihtiyaç vardı.
Investigation of the plasma malondialdehyde and glutathione levels in children with pervasive developmental disorder
Objective: Antioxidant defense systems comprise an important area of investigation in the etiopathogenesis of schizophrenia. The studies in the adult population reveal conflicting results and this points out that the child population should be studied as well.

Method: In this study, we compared children, with pervasive developmental disorder (n=35), and 60 children diagnosed as attention deficit hyperactivity disorder according to DSM-IV criteria on the measures of antioxidant defense systems.

Results: Gluthatione (GSH), which is regarded as an important element of antioxidant defense system was found higher in the study (pervasive developmental disorder) group but the difference was not significant. Malondialdehyde (MDA) levels did not show any statistically significant difference.

Conclusions: This result contradicts the results from the adult schizophrenia studies where MDA has been found to be elevated in most studies. However, there is a necessity to reasearch this area on a larger population.
