Conclusion: High XO and MDA levels in BD (Type I-Euthymic phase) may show that the disease still continues with oxidative stress in molecular level, when combined with the previous findings of high oxidative stress in acute manic phase of BD.

Abstract

Objectives: There hasn't been any study measuring (Xanthine Oxidase), and MDA (Malondialdehyde) enzymes in euthymic bipolar disorders yet. In bipolar patients, MDA levels were already known to be high. In remission phase (euthymic phase), XO and MDA, are not known to be whether high or low. In this study, we aimed to find out levels of these molecules in euthymic episode of Bipolar Disorder. Method: Twenty-two patients with bipolar disorders (İB) in euthymic phase and twenty-two healthy control subjects were included in this study. XO, and MDA have been studied in serum. DSM-IV based (Diagnostic and Statistical Manual of Mental Disorders) diagnosis of BD and being at least for a month in euthymic phase was established by a psychiatrist. Results: The mean value of patients' serum XO levels was significantly higher than those of the controls. Mean serum MDA levels were found to be increased in patients compared to controls. There is a correlation between XO and MDA levels. Conclusion: High XO and MDA levels in BD (Type I-Euthymic phase) may show that the disease still continues with oxidative stress in molecular level, when combined with the previous findings of high oxidative stress in acute manic phase of BD.

Özet

Amaç: Halen ötimik ikiuçlu bozuklukta ksantin oksidaz (XO) ve Malondialdehit (MDA) enzim düzeyini ölçen bir çalışma yoktur. İkiuçlu hastalarda oksidan molekül MDA seviyeleri yüksek olduğu bilinmektedir. Remisyon döneminde (ötimik evre) oksidan/antioksidan dengede yeralan XO ve MDA'nın yüksek veya düşük olduğu bilinmemektedir. Bu çalışmada bu moleküllerin düzeylerini ikiuçlu hastaların ötimik evrelerinde ölçmeyi amaçladık. Yöntem: 22 ikiuçlu bozukluğu olan ötimik hasta ve 22 sağlıklı kontrol çalışmaya dâhil edildi. Bu çalışmada XO ve MDA'nın serum düzeyleri ölçüldü. Bir psikiyatrist tarafından DSM-IV'e göre yapılan değerlendirmede hastanın en azından bir ay ötimik fazda olması çalışmaya dahil edilme ölçütü olarak kabul edildi. Bulgular: Hastalarda XO serum düzeylerinin ortalama değeri kontrollerin değerlerinden yüksekti. Ortalama serum MDA düzeyleri ikiuçlu hastalarda kontrollere göre artmış bulundu. XO ve MDA düzeyleri arasında korelasyon vardı. Sonuç: Daha önceki çalışmalarda bulunan ikiuçlu bozukluğun akut manik safhasında yüksek oksidatif stres ve remisyonda (ötimik evre) olan hastalarda da yüksek XO ve MDA düzeyleri bulunması, hastalığın moleküler seviyede oksidatif stresle devam etmekte olduğunu gösterebilir.
