Abstract

Doxorubicin is an anthracycline group antibiotic and has long been used as an antineoplastic agent. The most important side effect that limits the usage of doxorubicin is cardiotoxicity, which is observed at cumulative doses. We investigated the protective effect of clarithromycin that is known to have antioxidant and anti-inflammatory effects against Doxorubicin related cardiotoxicity. The aim of our study was to evaluate the effects of clarithromycin in the antioxidant enzyme status and myocardium of doxorobucine-treated rats. A total of 28 adult, male Wistar rats (200-250 g) were divided into 4 groups. Group I was the control group, rats in group 2 were administered doxorubicin, rats in group 3 were administered clarithromycin, and rats in group 4 were administered Doxorubicin + Clarithromycin. Following the scarification of all rats, antioxidant (glutathione) and oxidant (malodialdehyde) levels were measured in the cardiac tissue. Additionally, the cardiac muscles were evaluated histopathologically via hematoxylin eosin staining. The antioxidant amount (glutathione) was significantly higher in the treatment group compared to the doxorubicin group (p= 0.025), whereas the amount of oxidant (malondialdehyde) was significantly lower (p= 0.022). The histopathological examination revealed significant cardiotoxicity in the Doxorubicin group and significant reduction in the cardiotoxicity in the Doxorubicin + Clarithromycin group. The results obtained in this study provide evidence for the usefulness of the clarithromycin as a cardioprotective agent.

Özet

Doksorubisin antrasiklin grubu antibiyotiktir ve uzun süredir antineoplastik ajan olarak kullanılmaktadır. Doksorubisin kullanımını kısıtlayan en önemli yan etkisi kümülatif dozlarda gözlenen kardiyotoksisitedir. Antioksidan ve antienflamatuar etkileri bilinen klaritromisinin, doksorubisin ilişkili kardiyotoksisiteye karşı koruyucu etkisini araştırdık. Çalışmamızın amacı doksorubisin ile tedavi edilen ratlarda klaritromisinin myokarda ve antioksidan enzimler üzerine etkilerini değerlendirmektir. Çalışmaya alınan toplam 28 yetişkin erkek Wistar ratı (200-250 g) 4 gruba ayrıldı. Grup 1 kontrol grubuydu, grup 2’ de ki ratlara doksorubisin, grup 3’ de ki ratlara klaritromisin ve grup 4’ e doksorubisin+klaritromisin (tedavi grubu) uygulandı. Skarifikasyonu takiben tüm ratların kalp dokusunda antioksidan (glutatyon) ve oksidan (malodialdehid) düzeyleri ölçüldü. Buna ek olarak myokard dokusu hematoksilen-eozin ile boyanarak histopatolojik olarak değerlendirildi. Antioksidan (glutatyon) miktarı, tedavi grubunda doksorubisin grubuyla karşılaştırıldığında önemli derecede yüksekti (p= 0.025), oysa oksidan (malodialdehid) miktarı önemli derecede düşük saptandı (p= 0.022). Histopatolojik değerlendirmede doksorubisin grubunda ciddi kardiyotoksisite saptanırken doksorubisin + klaritromisin uygulanan grupta kardiyotoksisite de ciddi azalma belirlendi. Bu çalışmada elde edilen sonuç, klaritromisinin doxorubisine bağlı kardiyotoksitenin engellenmesinde kullanılabilecek kardiyoproduktif etkiye sahip bir ajan olduğudur
