Amaç: Bu çalışmada şizofreni hastalarında klozapin tedavisinin hipokampus üzerindeki etkilerinin proton manyetik rezonans spektroskopi (1 H-MRS) ile değerlendirilmesi amaçlanmış; metabolit düzeylerindeki değişimle psikopatoloji ve bilişsel işlevlerdeki değişim arasındaki ilişki incelenmiştir. Yöntem: Şizofreni hastaları (n=16) 12 haftalık klozapin tedavisi öncesi ve sonrası 1 H-MRS, Pozitif ve Negatif Sendrom Ölçeği (PANSS), Klinik Global İzlenim Ölçeği (KGİ) ve nörobilişsel test bataryasıyla; sağlıklı kontroller (n:8) bir kez nörobilişsel test bataryası ve 1 H-MRS’le değerlendirilmiştir. 1 H-MRS’de sağ ve sol hipokampus multivoksel ve sol hipokampus tek voksel ölçümlerinde NAA/Cr, Cho/Cr, MI/Cr oranları hesaplanmıştır. Bulgular: İzlem sonrasında tedavinin başlangıcına göre PANSS ve KGİ puanlarında azalma, Rey İşitsel-Sözel Öğrenme Testi anlık hatırlama ve toplam öğrenme, Sözel Akıcılık Kategori Testi, Wechsler Bellek Ölçeği gecikmiş bellek test puanlarında artma gözlenmiştir. Hipokampus multivoksel ve tek voksel ölçümlerinde NAA/Cr, Cho/ Cr, MI/Cr düzeylerinde klozapin öncesinde hasta grubuyla sağlıklı kontroller arasında; hastalarda 12 haftalık klozapin tedavisi öncesi ve sonrası arasında fark olmadığı saptanmıştır. 1 H-MRS’yle ölçülen metabolit düzeylerindeki değişimle psikopatoloji puanları ve bilişsel test puanlarındaki değişim arasında ilişki saptanmamıştır. Sonuç: Klozapinin hipokampustaki 1 H-MRS bulguları üzerine etkilerini inceleyen ilk uzunlamasına çalışmadır. Klozapin tedavisiyle 1 H-MRS bulgularında anlamlı değişiklik saptanmamıştır. Bu konuda nihai bir sonuca varmak için klozapinin daha geniş örneklem ve daha uzun izlem süresi içeren çalışmalarla incelenmesi gereklidir.
Effect of Clozapine on Proton Magnetic Resonance Spectroscopy Findings in Hippocampus
Objective: The purpose of this study was to investigate the effect of clozapine on proton magnetic resonance spectroscopy (1 H-MRS) findings in hippocampus in patients with schizophrenia. In addition, the relationship between the change in 1 H-MRS findings and the change in psychopathology and neurocognitive functions was evaluated. Method: Patients with schizophrenia (n=16) were assessed with the Positive and Negative Syndrome Scale (PANSS), Clinical Global Impression Scale (CGI), a neurocognitive test battery and 1 H-MRS at baseline, and twelve weeks after the initiation of clozapine. Healthy controls (n=8) were assessed once with a neurocognitive test battery and 1 H-MRS. Bilateral multivoxel and left single voxel NAA/Cr, Cho/Cr, MI/Cr was calculated in the hippocampi. Results: After 12 weeks of clozapine treatment, PANSS and CGI scores decreased; immediate recall, cumulative learning subtests of the Rey Auditory Verbal Learning Test, Category Verbal Fluency Test and Wechsler Memory Scale’s visual reproduction delayed subtest scores increased significantly. Compared with healthy controls and patients after clozapine, hippocampi multivoxel and single voxel NAA/Cr, Cho/ Cr, MI/Cr ratios were not different in patients before clozapine. No significant correlations between change in 1 H-MRS metabolite ratios and change in psychopathology, neurocognitive functions were detected. Conclusion: This study is the first longitudinal study to investigate the effect of clozapine in hippocampus with 1 H-MRS. There were no significant changes in 1 H-MRS findings in hippocampi after twelve weeks of clozapine treatment. Clozapine’s effect in hippocampus should be investigated further in longer follow up studies with larger samples to reach a final conclusion.
