Abstract

Objective: The purpose of this study was to test the hypothesis thThis study was planned to investigate the antipneumocystis activity of terbinafine in a rat model. Material and Methods: Rats were obtained from the Hakan Çetinsaya Experimental and Clinical Research Institutions, Erciyes University, Kayseri, Turkey. Terbinafine administered orally in doses of 40, 80, 120 and 160 mg/kg/day after nine weeks of immunosuppression with dexamethasone to facilitate the development of acute Pneumocystis carinii penumoniae (PCP). Results: Untreated animals showed P. carinii infection levels with a mean (±standard deviation) log number of cysts per gram of lung tissue of 4.6±1.6 at the end of the experiment. Terbinafine administered at a dose of 160 mg/kg/day significantly reduced the log number of cysts per gram to 2.2±1.5. The therapeutic efficacy of terbinafine administered at 160 mg/kg/day (log 2.2±1.5 cysts/lung) was similar to that obtained with trimethoprim-sulfamethoxazole (TMP-SMX), 50/250 mg/kg/day (p<0.001). A reduction in the number of cysts was also observed in infected animals treated with 80, and 120 mg of terbinafine/kg/day, although the results were not statistically significant (p>0.05). Conclusion: In our model, the efficacy of terbinafine in PCP has been found to be dose dependent. Turkish Başlık: Pneumocystis carinii'ye Terbinafinin Etkisinin Rat Modelinde Değerlendirilmesi Anahtar Kelimeler: Pneumocystis carinii; rat modeli; terbinafin Amaç: Bu çalışma rat modelinde terbinafinin anti-Pneumocystis aktivitesini belirlemek için planlanmıştır. Gereç ve Yöntemler: Ratlar Erciyes Üniversitesi Deneysel ve Klinik Araştırma Merkezin'den sağlanmıştır. Dokuz hafta boyunca akut Pneumocystis carinii pnömonisi (PCP) oluşturmak üzere, deksamethazon ile immünsüpresyon yapılan ratlara oral olarak 40, 80, 120 ve 160 mg/kg/gün terbinafin verildi. Bulgular: Çalışmanın sonunda tedavi almayan grupda PCP enfeksiyon düzeyi ortalama (±standart sapma) akciğer dokusu gramındaki kist sayısı log 4.6±1.6 idi. Terbinafin 160mg/kg/gün uygulanan grupta gramdaki kist sayısında önemli düşüş gözlendi log 2.2±1.5. Terbinafin 160mg/kg/gün uygulanan tedavi etkinliği, trimetoprim-sulfametoksazol (TMP-SMX), 50/250 mg/kg/gün uygulaması ile benzer sonuç verdi (p<0.001). Terbinafin 80 ve 120 mg/kg/gün uygulamalarında da kist sayısında düşüş görülmekle birlikte bu değerler istatistiksel olarak anlamlı değildi (p>0.05). Sonuç: Bizim modelimizde terbinafinin PCP etkinliği doza bağlı bulundu.
