    (2014) Kirnap, Mahir; Boyvat, Fatih; Akdur, Aydincan; Karakayali, Feza; Arslan, Gulnaz; Moray, Gokhan; Haberal, Mehmet; https://orcid.org/0000-0002-8726-3369; https://orcid.org/0000-0002-1874-947X; https://orcid.org/0000-0003-2498-7287; https://orcid.org/0000-0002-3462-7632; 24635819; AAH-9198-2019; F-4230-2011; AAA-3068-2021; AAB-3888-2021; AAE-1041-2021; AAJ-8097-2021
    Objectives: Locoregional therapy may decrease the tumor stage and enable liver transplant in patients who have hepatocellular cancer. The purpose of the present study was to assess the relation between locoregional therapy and recurrence of hepatocellular carcinoma after transplant. Materials and Methods: In 50 patients who had liver transplant for treatment of end-stage liver disease from hepatocellular carcinoma and cirrhosis, outcomes were evaluated for associations with locoregional therapy before transplant and Milan criteria. Results: Most patients had locoregional therapy before transplant (31 patients [62%]: transarterial catheter radiofrequency ablation alone, 16 patients; chemoembolization alone, 10 patients; both transarterial catheter radiofrequency ablation and chemoembolization, 5 patients). Follow-up at median 90 months after transplant showed that 9 patients (18%) had recurrence at median 45 months (range, 120 +/- 12 mo) (recurrence: locoregional therapy, 5 of 31 patients [16%]; no locoregional therapy, 4 of 19 patients [21%]; not significant). Locoregional therapy was associated with a significantly lower frequency of recurrence in patients who were outside the Milan criteria. Conclusions: In patients who have liver transplant for treatment of hepatocellular carcinoma, preoperative locoregional therapy may decrease recurrence in patients who are outside the Milan criteria.

    Treatment of Liver Transplant Recipients Who Have Chronic Hepatitis C Virus Infection
    (2014) Korkmaz, Murat; https://orcid.org/0000-0002-9333-782X; 24635788; AAM-1330-2020
    Chronic hepatitis C virus infection is the most common cause of chronic liver disease and indication for liver transplant in Western countries. Viral infection may recur after transplant in most patients. The diagnosis of histologic recurrence of hepatitis C virus infection after liver transplant may be difficult and may be confused with acute cellular graft rejection. Characteristics of the recipient, donor, virus, and transplant may be associated with disease progression. Treatment of hepatitis C virus infection has a positive effect on the outcome of liver transplant. There are 3 approaches used to minimize recurrent hepatitis C virus infection after liver transplant: antiviral therapy before transplant, antiviral preventive and preemptive treatment after transplant, and treatment of established reinfection. Protease inhibitors are being evaluated in patients who have severe hepatitis C virus recurrence after liver transplant. Liver graft survival is less frequent after revision transplant. Several new drugs currently are being evaluated in clinical trials for treatment of hepatitis C virus infection.

    Hepatitis B- and Hepatitis D-Virus Related Liver Transplant: Single-Center Data
    (2015) Ocal, Serkan; Korkmaz, Murat; Harmanci, Ozgur; Ensaroglu, Fatih; Akdur, Aydincan; Selcuk, Haldun; Moray, Gokhan; Haberal, Mehmet; 0000-0002-3462-7632; 0000-0002-8726-3369; 0000-0003-3719-9482; 0000-0002-9333-782X; 0000-0003-2498-7287; 0000-0002-8445-6413; 0000-0002-0643-4980; 25894142; AAJ-8097-2021; AAA-3068-2021; ABH-4817-2020; AAM-1330-2020; AAE-1041-2021; AAJ-6976-2021
    Objectives: Hepatitis B and D virus coinfection or superinfection lead to chronic liver disease and have poor treatment results and poor prognosis. After transplant, these patients have difficult problems. We aimed to report long-term data of liver transplant recipients who had hepatitis B and D virus-related chronic liver disease. Materials and Methods: This retrospective, longitudinal study included 25 consecutive hepatitis B surface antigen-positive patients with anti-hepatitis D virus antibodies. Patient data (age, sex, antiviral treatment, posttransplant use of hepatitis B hyperimmunoglobulin and/or nucleoside/nucleotide analogues, the presence of hepatocellular carcinoma, age at transplant, follow-up) were extracted from patient records. Results: Females comprised 32% patients. The median age was 44 years (range, 23-63 y). The serum Hepatitis B envelope antigen level was negative in all patients. At the time of transplant, 4 patients were positive for hepatitis B virus DNA and 11 patients also had hepatocellular carcinoma. Posttransplant follow-up was 59 months (range, 3-120 mo). During follow-up, 4 patients died, 4 patients were lost to follow-up, and 17 patients were alive. Posttransplant survival of patients with hepatocellular carcinoma was 50.45 months (range, 3-84 mo) and without hepatocellular carcinoma was 65.8 months (range, 4-120 mo). There were 3 patients who had acute rejection and were treated successfully with pulse doses of prednisolone. Hyperimmunoglobulin therapy was used in conjunction with oral nucleotide/nucleoside analogues for 12 months (range, 3-24 mo) and then stopped. After transplant, 4 patients had antiviral medicine changed to adefovir or entecavir because of drug resistance, and otherwise all patients remained negative for hepatitis B virus DNA during follow-up. Conclusions: Patients transplanted for hepatitis B and D virus cirrhosis, even with hepatocellular carcinoma, had favorable prognosis and good long-term results. Close follow-up of patients and effective viral suppression with suitable drugs were key factors for efficient patient care.
