Öğe The Course of Endoscopic Treatment Success in Biliary Complications After Living Donor Liver Transplantation(Galenos Publ House, 2024) Ataman, Engin; Harputluoglu, Murat; Bilgic, Yilmaz; Cagin, Yasir Furkan; Erdogan, Mehmet Ali; Kutlu, Ramazan; Kutluturk, KorayObjective: Our aim was to present the results of endoscopic retrograde cholangiopancreatography (ERCP) after living donor liver transplantation (LDLT) between February 2015 and June 2021. Methods: Clinical data included LDLT indications, time to perform ERCP after LDLT, number of ERCP procedures, indications for ERCP, and all treatment outcomes, including ERCP, percutaneous, and surgical interventions. We compared the obtained data with our previous study published by our team in 2018, which included 446 patients who underwent ERCP for biliary complications after LDLT between 2005 and 2015. Results: We performed ERCP in 283 of 1506 patients with LDLT who underwent duct-to-duct anastomosis during transplantation and then developed biliary complications. Our endoscopic success rates were 60.9% and 71.0% in the previous and present studies, respectively. Conclusions: Our findings suggest that the success rate of endoscopic treatment of biliary complications in patients with LDLT increases in correlation with the increasing experience of clinicians treating these patients.Öğe Early therapeutic plasma exchange may improve treatment outcomes in severe acute toxic Hepatitis(Pergamon-Elsevier Science Ltd, 2021) Berber, Ilhami; Cagin, Yasir Furkan; Erdogan, Mehmet Ali; Ataman, Engin; Gozukara, Harika; Erkurt, Mehmet Ali; Yildirim, OguzhanBackground and objectives: Acute toxic hepatitis can result in a different clinical course from a completely curable disease to subacute hepatitis, chronic hepatitis, and fulminant hepatitis failure, which is quite mortal. For this purpose, therapeutic plasma exchange (TPE) can be used for improving treatment outcomes by reducing the harmful substances caused with and/or without liver function in acute toxic hepatitis. We aimed to evaluate treatment outcomes in severe acute toxic hepatitis patients who applied early TPE procedure. Materials and Methods: A total of 335 patients who received TPE between 2010-2021 were retrospectively screened and 59 (male/female, 30/29; min/max-age, 22-84) patients with acute toxic hepatitis who underwent TPE in the first 24 h were included in the study. TPE was performed in patients who had high total bilirubin level (>10 mg/dL). Laboratory parameters of the patients before and after the TPE procedure, number of patients developed complications of acute toxic hepatitis and mortality rates were evaluated for effectiveness of TPE. Results: Acute toxic hepatitis was associated with hepatotoxic drugs in 44 (74.5 %), herbal medication 6 (10.2 %), mushroom poisoning 6 (10.2 %) and with substance abuse 3 (5.1 %) in patients. When the patients were compared based on INR, liver function tests, ammonia, lactate and Model For End-Stage Liver Disease (MELD) score at baseline, 48 h after TPE (independently of TPE number) and before final state a statistically significant decrease was observed in all parameters (p < 0.05). Fifty three (90 %) of patients improved without complications, the remaining 6 (10 %) patients were diagnosed with fulminant hepatitis. All these remaining patients died before liver transplantation (LTx) could be performed. Conclusion: TPE is a safe, tolerable therapy option and early TPE may improve treatment outcomes in severe acute toxic hepatitis.Öğe Estimated Dialysate Magnesium Clearance in Peritoneal Dialysis Patients(Wiley-Blackwell, 2015) Koz, Suleyman; Sahin, Idris; Koz, Sema Tulay; Terzi, Zafer; Ataman, Engin; Akkus, Hadi[Abstract Not Available]Öğe Gemsitabin ve cisplatin alan akciğer karsinomu olan hastalarda ERCC1 inprognoz ile ilişkisi(İnönü Üniversitesi, 2013) Ataman, EnginAkciğer kanseri tüm dünyada kadın ve erkeklerde kanserden ölümlerin en sık sebebidir. Küçük hücreli dışı akciğer kanserlerinde platin bazlı kemoterapiler standart tedavidir. Ancak her ilacın olduğu gibi platin bazlı kemoterapilerinde yararının yannda ciddi toksisite ve yan etkileri vardır. Hangi hastalarda hangi tür kemoterapi ajanlarının kullanılacağı, konusunda tedaviden maximum fayda ve minimum zarar elde etmek amacıyla bazı ipuçlarına ihtiyaç vardır. Enzyme repair cross- complementation group 1 (ERCC1) in akciğer kanserinde platin alan hastalarda prognoz üzerindeki etkisinin araştırılarak ileri dönemlerde yeni tedavi başlanacak hastalarda tedavi seçiminde etkili olup olmayacağı amacıyla bu çalışma hazırlanmıştır. Hastalar ve Yöntem: Çalışmaya İnönü Üniversitesi Tıbbi Onkoloji kliniğinde 2008?2012 tarihleri arasında sisplatin-gemsitabin kombinasyonu ile tedavi edilen 26 akciğer kanserli hasta alındı. Hastaların tıbbi kayıtları retrospektif olarak değerlendirildikten sonra immünhistokimyasal inceleme için doku örnekleri uygun olanlar çalışmaya dahil edildi. Tümoral dokuda ERCC1 ekspresyonu immünhistokimyasal boyama tekniği ile değerlendirildi. Bulgular: ERCC1 boyanma şiddeti ve dağılımına göre 4 gruba ayrıldı. 6 hastada 0, 8 hastada +1, 5 hastada +2, 7 hastada +3 bulundu. O ve +1 olanlar ERCC1 negatif kabul edilirken, +2 ve +3 olanlar ERCC1 pozitif kabul edildi.. Tedavi sonrası yapılan değerlendirmede 1 hastada iyi parsiyel cevap (%3,8) , 1 hastada parsiyel cevap (%7,7),5 hastada stabil hastalık (%19,2) ve 18 hastada progresyon (%69,2) gözlendi. Çalışmanın bittiği tarih itibariyle 13(%50) hasta exitus olmuşken 13(%50) hasta yaşıyordu. Hastaların genel sağkalımı ortalama 15 (3?44) ay olarak bulundu. progresyonsuz sağ kalımı ise 9(2?25) ay olarak bulundu. Çalışmamızda genel sağkalım ve hastalıksız sağkalım ile ERCC1 arasında anlamlı bir fark bulunamadı. Sonuç: : ERCC1 ile tedavi cevabı ve sağkalım arasındaki ilişki incelendiğinde genel olarak literatürle benzer sonuçlar bulunmuştur. Hasta sayısı az olmakla birlikte çalışmalardaki sonuçlar arasındaki farklılıklar da dikkate alındığında ERCC1 negatif VI ve pozitif gruplar arasındaki farkın istatistiksel anlamlılığa ulaşmamış olmasını tek başına buna bağlamamak gerekmektedir.Öğe HBV viral load and tumor and non-tumor factors in patients with HBV-associated HCC(Kare Publ, 2024) Ataman, Engin; Harputluoglu, Murat; Carr, Brian Irving; Gozukara, Harika; Ince, Volkan; Yilmaz, SezaiBackground and Aim: Several tumor and non-tumor factors affect the prognosis of hepatocellular carcinoma (HCC) patients. This study aimed to investigate the effects of hepatitis B virus (HBV) viral load on tumor and non-tumor factors in patients with HBV-associated HCC. Materials and Methods: Patients with hepatitis B and HCC who presented Transplantation Institute, were included in our study. Patients were divided into two groups according to the presence or absence of HBV-DNA, and it was determined whether there were differences between these two groups with respect to tumor and non-tumor parameters. Results: Comparison of serum alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), hepatitis B surface antigen (HBsAg), and C-reactive protein (CRP) levels between HBV-DNA negative and positive patients showed significant differences (respectively p<0.01, p<0.01, p<0.05, and p<0.05). A major finding was a very significant difference between the two patient groups in terms of portal vein invasion (PVI) and venous invasion (p<0.001 and p<0.01, respectively). However, there was no significant difference in metastasis or lymph node involvement between HBV-DNA negative and positive patients. Conclusion: Our findings suggest that HBV viral load plays an important role in PVI in HCC patients, and there is a significant relationship between HBV viral load and inflammation.
