Abstract: Abstracts P-25 SLOWER FIBROSIS PROGRESSION IN HEPATITIS C HEMOPHILIAC PATIENTS? Dauana O. Bastos, Christini Emori, Sandra V. Antunes, Flavia Appel, Maria Lucia Ferraz ~o Paulo, Sa ~o Paulo, Brazil Universidade Federal de Sa Introduction: The improvement in the treatment of hemophilia from the 900 s, as well as the advent of interferon-free therapy against HCV enabled a better evolution of these special group of patients. However, the impact of hemophilia on the progression of liver fibrosis is still not completely understood. Objectives: To evaluate the progression of liver fibrosis in hemophiliac patients with HCV using non-invasive methods after ten years of follow-up. Casuistic and Method: Retrospective cohort study of hemophiliac patients with HCV evaluated in 2007 and reassessed 10 years later (2017/2018). Hepatic fibrosis was indirectly evaluated by APRI and transient hepatic elastography by Fibroscan Ò - EHT). Results: Sixty-six hemophiliac patients were evaluated in 2007 (all men, median age 31.5 years, 87.9% hemophilia A). Forty-two patients could be reevaluated in 2017/2018. Thirty-three patients were treated with 90.9% SVR; thus, after 10 years, 30 patients were non-viremic and 12 were viremic (3 without SVR and 9 untreated). APRI values were low in both periods but showed a significant reduction in treated patients (0.36 vs 0.20, p <0.001), remaining stable in non-treated (0,61 vs 0,51, p=NS). Fibrosis by EHT was assessed only in 2017/2018 and also showed results compatible with low stages of fibrosis in treated and even in non-treated patients (4.75 and 5.25 kPa, respectively). Conclusions: After ten years of follow-up the results suggest a slower progression and a more benign evolution of hepatic fibrosis among hemophiliacs. Antiviral therapy against HCV showed an elevated response rate, similar to the general population. https://doi.org/10.1016/j.aohep.2021.100389 P-26 PORTAL VENOUS THROMBOSIS IN TRANSPLANTED CIRRHOTIC PATIENTS AT THE “HOSPITAL CL

Objective: Characterize the presence of PVT in patients with LT. Methods: Retrospective observational study between January 1, 2014 and February 28, 2018. Clinical records, laboratory and images were reviewed. Results: 82 patients were included; Age 58 (21-71) years; Etiology: non-alcoholic fatty liver 40.2%, alcoholic liver disease 20.7%, autoimmunity 13.4%, and hepatitis C 8.5%; Child-Pugh: 7.3% A, 30.4% B and 62.2% C; MELD-Na 22 (8-40). PVT was diagnosed before or during LT in 26.8%: Child A 16.6%, B 16.0%, and C 33.3%; MELD-Na 25 (1240) in those with PVT vs 21 (8-40) in those without PVT (non significant, NS); 34% had hepatocarcinoma (32.1% with PVT vs. 24.4% Annals of Hepatology 24 (2021) 100366 without PVT; NS). Diagnosis of PVT was 77.2% pre LT and almost 1/4 during transplant surgery. The extension of the PVT was complete occlusion in 11.7%, partial in 70.5%; 11.7% had only intrahepatic branches compromised..
