Colonic Epstein-Barr Virus-Associated Mucocutaneous Ulcer Associated With Ulcerative Colitis.

Epstein-Barr virus-associated mucocutaneous ulcer is a rare lymphoproliferative disorder that occurs in immunosuppressed states that can develop in the gastrointestinal tract and mimic inflammatory bowel disease or other malignancies. We present the case of a 61-year-old man who presented with concurrent acute severe ulcerative colitis and colonic Epstein-Barr virus-associated mucocutaneous ulcer requiring rituximab therapy and a subtotal colectomy.

Hepatocellular carcinoma incidence post direct-acting antivirals in hepatitis C-related advanced fibrosis/cirrhosis patients in Australia.

BACKGROUND: Despite efficacy in HCV eradication, direct-acting antiviral (DAA) therapy has raised controversies around their impact on hepatocellular carcinoma (HCC) incidence. Herein we reported the first Australian data on HCC incidence in DAA-treated HCV patients with advanced fibrosis/cirrhosis. METHODS: We conducted a retrospective single center study of DAA-treated HCV patients with advanced fibrosis/cirrhosis from April 2015 to December 2017. Patients with prior HCC were included if they had complete response to HCC treatment. RESULTS: Among 138 patients who completed DAA therapy, 133 (96.4%) achieved sustained virologic response (median follow-up 23.8 months). Ten had prior HCC and 5/10 (50.0%) developed recurrence, while de novo HCC developed in 7/128 (5.5%). Median time from DAA to HCC diagnosis was 34 weeks in recurrent HCC vs. de novo 52 weeks (P = 0.159). In patients with prior HCC, those with recurrence (vs. without) had shorter median time between last HCC treatment and DAA (12 vs. 164 weeks, P < 0.001). On bivariate analysis, failed sustained virologic response at 12 weeks (SVR12) (P = 0.011), platelets (P = 0.005), model for end-stage liver disease (MELD) score (P = 0.029), alpha fetoprotein (AFP) (P = 0.013), and prior HCC (P < 0.001) were associated with HCC post-DAA. On multivariate analysis, significant factors were prior HCC (OR = 4.80; 95% CI: 1.47-48.50; P = 0.010), failed SVR12 (OR = 2.83; 95% CI: 1.71-16.30; P = 0.016) and platelets (OR = 0.97; 95% CI: 0.95-0.99; P = 0.009). CONCLUSIONS: Our study demonstrates a high incidence of recurrent HCC in HCV patients with advanced fibrosis/cirrhosis treated with DAA. Factors associated with HCC development post-DAA were more advanced liver disease, failed SVR12 and prior HCC, with higher rates of recurrence in those who started DAA earlier.
