Abstract

Aim: The COVID-19 virus influenced the world since late 2019 and affected millions of people. Although there is no unambiguous evidence in the treatment of COVID-19, the combination of hydroxychloroquine and azithromycin entered the protocols globally to reduce virus replication and take advantage of its immunomodulatory effects. It has been stated that both drugs extend QTc. However, the frequency of QTc prolongation in combinational drug use, and its effect on the primary endpoint, as well as the predictive values of QTc prolongation are not clear. Methods: A total of 135 patients who received hydroxychloroquine, azithromycin, and oseltamivir for suspected / definitive COVID-19 with viral pneumonia were examined in this single-center, retrospective study, Results: The mean age was 55.6 (19.1) years, and 61 (45%) patients were female. According to the initial ECG values, the QTc1 value was 422.44 (35.72) ms, while the QTc2 value was 446.91 (36.71) ms (P500 ms was 6 (4.4%). The number of patients with prolongation in QTc values >60 ms was 7 (5.1%). The frequency of prolongation in QTc was 26% in intensive care unit patients, and 2% in low-risk patients in the inpatient unit. An elevation in troponin values >14 ng/L and a low GFR are predictors for QTc prolongation. None of these patients developed malignant arrhythmia or sudden cardiac death. Conclusion: Hydroxychloroquine and azithromycin combinations used in COVID-19 patients cause a prolongation in the QTc. The incidence of prolongation in QTc varies according to the comorbid characteristics and clinical status of the patients. Before starting hydroxychloroquine and azithromycin, the risk factors and clinical status of the patients should be well evaluated.

Özet

Amaç: COVID-19 virüsü 2019'un sonlarından bu yana tüm dünyayı ve milyonlarca insanı etkiledi. COVID-19 tedavisinde net bir kanıt olmamasına rağmen, hidroksiklorokin ve azitromisinin kombinasyonu, virüs replikasyonunu azaltmak ve immünomodülatör etkilerinden yararlanmak için dünya çapında protokollere girmiştir. Her iki ilacın ayrı ayrı kullanımlarında QTc'yi uzattığı belirtilmiştir. Bununla birlikte, kombinasyonel ilaç kullanımında QTc uzamasının sıklığı ve bunun birincil sonlanım noktası üzerindeki etkisi ve ayrıca QTc uzamasının prediktif değerleri net değildir. Yöntemler: Çalışma tek merkezli, retrospektif bir çalışma olarak tasarlandı. Viral pnömonili şüpheli / kesin COVID-19 nedeniyle hidroksiklorokin, azitromisin ve oseltamivir alan 135 hasta incelendi. Bulgular: Ortalama yaş 55,6 (19,1) yıldı ve 61 (%45) hasta kadındı. İlk EKG değerlerine göre QTc1 değeri 422,44 (35,72) ms, QTc2 değeri 446,91 (36,71) ms (P500 ms olan hasta sayısının 6 (%4,4) olduğunu gösterdi. QTc değerlerinde >60 ms uzaması olan hasta sayısı 7 (%5,1) idi. QTc'de uzama sıklığı yoğun bakım hastalarında %26 iken, yataklı servis birimindeki düşük riskli hastalarda sıklık %2 idi. Troponin değerlerinde >14 ng/L yükselme ve düşük GFR, QTc uzaması için belirleyicilerdir. Bu hastaların hiçbirinde malign bir aritmi veya ani kalp durması gelişmedi. Sonuç: COVID-19 hastalarında kullanılan hidroksiklorokin ve azitromisin kombinasyonları QTc'de uzamaya neden olur. QTc'de uzama insidansı, hastaların komorbid özelliklerine ve klinik durumuna göre değişir. Hidroksiklorokin ve azitromisine başlamadan önce, hastaların risk faktörleri ve klinik durumu iyi değerlendirilmelidir.
