Giris ve Amaç: Kronik hepatit C enfeksiyonu karaciger sirozu ve hepatoselüler karsinomun nedenleri arasindadir. Bu çalismada primer olarakkronik hepatit C’li heterojen bir hasta grubunda güncel olarak kullanilanikinci kusak direk etkili oral antivirallerin tedavi etkinligi ve yan etki profillerinin arastirilmasi amaçlanmistir. Gereç ve Yöntem: Retrospektifolan bu çalismaya ikinci kusak direk etkili oral antiviral tedavi alan 72hasta dahil edilmistir. Hastalara ait klinik ve laboratuvar verileri polikliniktakip dosyalarindan elde edilmistir. Bulgular: Hastalarin yas ortalamasi 58±14 olup, 39’u (%54) kadin idi. Baskin genotip 1b idi (%74.6).Non-sirotik, kompanse siroz ve dekompanse siroz hastalarin sayilari si-rasiyla; 56 (%77.8), 14 (%19.4) ve 2 (%2.8) idi. On sekiz hasta (%25)tedavi deneyimli idi. Paritaprevir/ritonavir/ombitasvir + dasabuvir, ledipasvir/sofosbuvir, ledipasvir/sofosbuvir + ribavirin, sofosbuvir + ribavirin, glekaprevir + pibrentasvir ve paritaprevir/ritonavir/ombitasvir +ribavirin alan hasta sayilari sirasiyla; 38 (%52.8), 13 (%18.1), 7 (%9.7),7 (%9.7), 6 (%8.3) ve 1 (%1.4) idi. Toplam 71 hasta tedaviyi tamamladive bunlarin 69’unda (%97.2) kalici viral yanit elde edildi. Ayrica baslangiç aspartat aminotransferaz, alanin amimotransferaz, gama glutamiltransferaz ve alfa fetoprotein düzeylerinde tedavi ile birlikte anlamli birdüsüs izlendi (p <0.05). Bilirübin düzeyleri ise tedavi esnasinda anlamlibir sekilde yükselmekle beraber (p <0.05), tedavinin sona ermesiyle birlikte düsüs göstermekteydi. Yan etki profilleri açisindan, kullanilan tümrejimlerde gözlenen yan etkiler hafif siddette olup, tedaviyi kesecek vasifta degildi. Sonuç: Ülkemizde kronik hepatit C infeksiyonunda güncelolarak kullanilan ikinci kusak direk etkili oral antiviraller yüksek etkinlikve düsük yan etki profiline sahiptirler
Background and Aims: Chronic hepatitis C infection is one of the causes of liver cirrhosis and hepatocellular carcinoma. The purpose of thisstudy was primarily to examine the treatment efficacy and side effectprofiles of second-generation direct-acting oral antivirals currently usedin a heterogeneous patient group with chronic hepatitis C. Materialsand Methods: This retrospective study included 72 patients who received second-generation direct-acting oral antiviral therapy. Clinical andlaboratory data of the patients were collected from outpatient follow-upfiles. Results: The mean age of the patients was 58±14 years, of which39 (54%) were women. The predominant genotype was 1b (74.6%).Patients with no cirrhosis, compensated cirrhosis, and decompensatedcirrhosis were 56 (77.8%), 14 (19.4%), and 2 (2.8%), respectively. Eighteen patients (25%) were treatment experienced. On the other hand,patients treated with paritaprevir/ritonavir/ombitasvir + dasabuvir, ledipasvir/sofosbuvir, ledipasvir/sofosbuvir + ribavirin, sofosbuvir + ribavirin,glecaprevir + pibrentasvir, and paritaprevir/ritonavir/ombitasvir + ribavirin were 38 (52.8%), 13 (18.1%), 7 (9.7%), 7 (9.7%), 6 (8.3%), and 1(1.4%), respectively. A total of 71 patients completed the treatment and69 of them (97.2%) was obtained sustained viral response. In addition,a significant decrease was observed in the initial aspartate aminotransferase, alanine aminotransferase, gamma glutamyl transferase, and alpha fetoprotein levels during treatment (p <0.05). Although bilirubinlevels increased significantly during treatment (p <0.05), they decreasedat the end of treatment. In terms of the side effect profile, side effectsobserved in all regimes were mild and not severe enough to discontinuetreatment. Conclusion: Therefore, the second-generation direct-actingoral antivirals widely used in chronic hepatitis C infection in our countryhave high efficacy and low side effect profile.
