Abstract

Clarithromycin is a macrolide antibiotic used for the treatment of pneumonia and acute exacerbations of COPD. It is usually well tolerated but it sometimes causes a long QT interval or increases the risk of arrhythmias. This study is designed to determine the effect of clarithromycin on QT interval. Thirty-one patients (18 males, 13 females) with the diagnoses of pneumonia or acute exacerbation of COPD were included in the study. The patients were separated into two groups randomly. Sixteen of them were treated with clarithromycin and 15 of them with a beta-lactam/beta-lactamase inhibitor combination. The antibiotics were administered intravenously during the first 3 days and orally for the following 7 days. ECG was performed just before the therapy and the 5th, 15th minutes and the 10th day of the therapy. QT interval and the corrected QT according to the heart rate (QTc) were determined. No significant difference of QTc values was detected between the two groups (p> 0.05). In conclusion, clarithromycin can be administered safely for the appropriate clinical indications in patients without a history of an additional disease or drug usage causing QT prolongation.

Özet

Klaritromisin, pnömoni ve kronik obstrüktif akciğer hastalığı (KOAH) akut alevlenmelerinde kullanılan makrolid grubu bir antibiyotiktir. Genellikle iyi tolère edilmesine rağmen, bazen elektrokardiyografi (EKG)'de QT aralığını uzatabilmekte ve aritmi riski yaratabilmektedir. Bu çalışma, klaritromisinin QT mesafesine etkisini saptamak amacıyla yapılmıştır. Çalışmaya KOAH akut alevlenme ve pnömoni tanılarıyla kliniğimize yatırılan 18'i erkek, 13'ü kadın, 31 hasta dahil edildi. Randomize olarak iki gruba ayrılan hastaların 16'sı klaritromisinle, 15'i beta-laktam/beta-laktamaz inhibitor kombinasyonu bir antibiyotik ile tedavi edildi. Kullanılan antibiyotikler ilk üç gün intravenöz (IV), sonraki yedi gün oral yolla verildi. Tedavi öncesinde, tedavinin 5. dakikası ve 15. dakikası ile 10. gününde EKG çekilip QT ve kalp hızına göre düzeltilmiş QT (QTc) değerleri saptandı. QTc değerleri incelendiğinde iki grupta da anlamlı fark saptanmadı (p> 0.05). Sonuç olarak, klaritromisinin uygun klinik endikasyonda, QT uzamasına yol açan ilave hastalık öyküsü ya da ilaç kullanımı olmayan hastalarda, güvenle kullanılabileceği düşünüldü
