Abstract

Objectives: The purpose of this study was to investigate platelet and plasma serotonin levels and platelet monoamine oxidase activity in patients with major depression and the influence of sertraline treatment on these biochemical measures. Methods: Twenty-one patients with major depression and 21 healthy controls matched for age, sex, and smoking status were recruited. Platelet and plasma serotonin levels and platelet monoamine oxidase activity were assessed after a oneweek drug-free interval (baseline) and six weeks after the initiation of sertraline treatment. Results: At baseline, the plasma serotonin levels were lower and platelet serotonin and monoamine oxidase levels were higher in the patient group compared to the controls. After six weeks of sertraline treatment, platelet serotonin and monoamine oxidase levels had decreased and plasma serotonin levels had increased, all approaching the levels in the controls. Conclusions: Our results support some earlier findings indicating that major depressive patients have higher platelet serotonin levels and monoamine oxidase activity and lower plasma serotonin levels as compared with healthy subjects. Additionally, these abnormal parameters seem to normalize during sertraline treatment. However, in contrast to the results of some previous studies, our findings suggest that these biochemical parameters are not useful for predicting the clinical response rate or time (i.e. early and late responder) to a selective serotonin reuptake inhibitor, sertraline.

Özet

Amaç: Bu çalışmanın amacı; majör depresyon hastalarında plazma, trombosit serotonin düzeyleri ile trombosit monoamin oksidaz aktivitesini araştırmak ve sertralin tedavisinin bu biyokimyasal ölçütler üzerine olan etkisini saptamaktır. Yöntem: Majör depresyonu olan 21 hasta ve yaş, cinsiyet özelliklerin bakımından eşleştirilmiş 21 sağlıklı kişi çalışmaya dahil edilmiştir. Trombosit ve plazma serotonin düzeyleri ve trombosit monoamin oksidaz aktivitesi bir haftalık ilaçsız dönem sonrasında ve sertralin tedavisine başlandıktan 6 hafta sonra değerlendirilmiştir. Bulgular: Başlangıçta, kontrollerle kıyaslandığında, hasta grubunun plazma serotonin düzeyleri daha düşük, trombosit serotonin ve monoamin oksidaz düzeyleri daha yüksek olarak bulunmuştur. 6 haftalık sertralin tedavisi sonrasında trombosit serotonin ve monoamin oksidaz düzeyleri azalırken, plazma serotonin düzeyleri artmış ve kontrol grubunun düzeylerine yaklaşmıştır. Sonuçlar: Bulgularımız depresyon hastalarında sağlıklı kontrollerle karşılaştırıldığında daha yüksek trombosit serotonin düzeyleri ve monoamin oksidaz aktivitesi ile düşük plazma serotonin düzeyleri bildiren diğer araştırma bulgularını destekler niteliktedir. Bununla birlikte, daha önceki bazı araştırma sonuçlarının aksine, bu biyokimyasal değişkenlerin bir seçici serotonin geri alımı inhibitörü olan sertralin ile yapılan tedaviye klinik yanıt oranını ve zamanını (erken ve geç cevap) kestirmede faydalı olmayacağı saptanmıştır.
