To achieve WHO's goal of eliminating hepatitis C virus (HCV), innovative strategies must be designed to diagnose and treat more patients. Therefore, we aimed to describe an implementation strategy to identify patients with HCV who were lost to follow‐up (LTFU) and offer them re‐linkage to HCV care. We conducted an implementation study utilizing a strategy to contact patients with HCV who were not under regular follow‐up in 13 countries from Latin America. Patients with HCV were identified by the international classification of diseases (ICD‐9/10) or equivalent. Medical records were then reviewed to confirm the diagnosis of chronic HCV infection defined by anti‐HCV+ and detectable HCV‐RNA. Identified patients who were not under follow‐up by a liver specialist were contacted by telephone or email, and offered a medical reevaluation. A total of 10,364 patients were classified to have HCV. After reviewing their medical charts, 1349 (13%) had undetectable HCV‐RNA or were wrongly coded. Overall, 9015 (86.9%) individuals were identified with chronic HCV infection. A total of 5096 (56.5%) patients were under routine HCV care and 3919 (43.5%) had been LTFU. We were able to contact 1617 (41.3%) of the 3919 patients who were LTFU at the primary medical institution, of which 427 (26.4%) were cured at a different institutions or were dead. Of the remaining patients, 906 (76.1%) were candidates for retrieval. In our cohort, about one out of four patients with chronic HCV who were LTFU were candidates to receive treatment. This strategy has the potential to be effective, accessible and significantly impacts on the HCV care cascade. [ABSTRACT FROM AUTHOR]

The A.A.E.E.H has developed this guideline for the best care of patients with hepatocellular carcinoma (HCC) from Argentina. It was done from May 2018 to March 2020. Specific clinical research questions were systematically searched. The quality of evidence and level of recommendations were organized according to GRADE. HCC surveillance is strongly recommended with abdominal ultrasound (US) every six months in the population at risk for HCC (cirrhosis, hepatitis B or hepatitis C); it is suggested to add alpha-feto protein (AFP) levels in case of inexeperienced sonographers. Imaging diagnosis in patients at risk for HCC has high specificity and tumor biopsy is not mandatory. The Barcelona Clinic Liver Cancer algorithm is strongly recommended for HCC staging and treatment-decision processes. Liver resection is strongly recommended for patients without portal hypertension and preserved liver function. Composite models are suggested for liver transplant selection criteria. Therapies for HCC with robust clinical evidence include transarterial chemoembolization (TACE) and first to second line systemic treatment options (sorafenib, lenvatinib, regorafenib, cabozantinib and ramucirumab). Immunotherapy with nivolumab and pembrolizumab has failed to show statistical benefit but the novel combination of atezolizumab plus bevacizumab has recently shown survival benefit over sorafenib in frontline.

Introduction: Although the effectiveness of direct-acting antivirals (DAAs) for the treatment of chronic hepatitis C virus (HCV) has been reported in real-world settings, predictive factors of treatment failure are lacking. Therefore, we sought to explore the baseline predictors of treatment response to DAAs., Methods: This was a prospective multicenter cohort study from the Latin American Liver Research Educational and Awareness Network (LALREAN) including patients who received DAA treatment from May 2016 to April 2019. A multivariate logistic regression model was conducted to identify variables associated with unachieved sustained virological response (SVR), defined as treatment failure (odds ratios [OR] and 95% confidence intervals [CIs])., Results: From 2167 patients (55.2% with cirrhosis) who initiated DAA therapy, 89.4% completed a full-course treatment (n = 1938). Median treatment duration was 12 weeks, and 50% received ribavirin. Definitive suspension due to intolerance or other causes was observed in only 1.0% cases (n = 20). Overall non-SVR12 was 4.5% (95% CI, 3.5-5.7). There were no significant differences in treatment failure according to HCV genotypes and the degree of fibrosis. Independently associated variables with DAA failure were liver function impairment according to the Child-Pugh score B OR, 2.09 (P = .06), Child-Pugh C OR, 11.7 (P < .0001); and liver transplant (LT) recipient OR, 3.75 (P = .01)., Conclusion: In this real-life setting, higher DAA treatment failure rates were observed in patients with decompensated cirrhosis and in LT recipients. These predictive baseline factors should be addressed to individualize the appropriate time-point of DAA treatment (NCT03775798; www., Clinicaltrials: gov)., (© 2020 Wiley Periodicals LLC.)

The COVID-19 pandemic declared in March 2020, has generated worldwide concern due to its effect on the health of the population and the potential health collapse. The strategy of "flattening the curve" through social distancing made it possible to adapt the resources of the health system to patients with COVID-19, but results in other areas of health could not be predicted. The objective of this work was to analyze the consequences of the pandemic on liver transplantation in general and for hepatocarcinoma (HCC). The following studies were carried out: a) a retrospective analysis using data from the CRESI / INCUCAI to compare admission to the waiting list, mortality on the list, donation and liver transplantation from 03/20 to 08/15, 2019 and the same period in 2020, and b) a survey of the transplant centers with the highest transplant activity to assess the effect of the measures taken in different institutional and regional situations. The first analysis showed a 55% decrease in liver transplants, with a similar reduction in donation and admission to the liver waiting list; while HCC transplantation rose from 10% in 2019 to 22% in 2020. The second analysis showed that the occupancy rate of beds by COVID-19 patients / week was variable: from 0.4% to 42.0%. The number of surgeries, hepato-bilio-pancreatic, resection of HCC and liver transplantation, were reduced by 47%, 49%, 31% and 36% respectively. The reduction in transplant activity mainly affected centers with high occupancy due to COVID-19. The final long-term outcome will need to be assessed.

Background & Aims: Data from Europe and North America have been published regarding the risk of developing hepatocellular carcinoma (HCC) after treatment with direct antiviral agents (DAA). We proposed to evaluate cumulative incidence and associated risk factors for de novo HCC., Methods: This was a prospective multicentre cohort study from Latin America including 1400 F1-F4-treated patients with DAAs (F3-F4 n = 1017). Cox proportional regression models (hazard ratios, HR and 95% CI) were used to evaluate independent associated variables with HCC. Further adjustment with competing risk regression and propensity score matching was carried out., Results: During a median follow-up of 16 months (IQR 8.9-23.4 months) since DAAs initiation, overall cumulative incidence of HCC was 0.02 (CI 0.01; 0.03) at 12 months and 0.04 (CI 0.03; 0.06) at 24 months. Cumulative incidence of HCC in cirrhotic patients (n = 784) was 0.03 (CI 0.02-0.05) at 12 months and 0.06 (CI 0.04-0.08) at 24 months of follow-up. Failure to achieve SVR was independently associated with de novo HCC with a HR of 4.9 (CI 1.44; 17.32), after adjusting for diabetes mellitus, previous interferon non-responder, Child-Pugh and clinically significant portal hypertension. SVR presented an overall relative risk reduction for de novo HCC of 73% (CI 15%-91%), 17 patients were needed to be treated to prevent one case of de novo HCC in this cohort., Conclusions: Achieving SVR with DAA regimens was associated with a significant risk reduction in HCC. However, this risk remained high in patients with advanced fibrosis, thus demanding continuous surveillance strategies in this population., (© 2019 John Wiley & Sons A/S.

We describe a clinical case of a kidney transplant patient who presented a sudden elevation of his liver function tests. Once we ruled out the most frequent causes of acute hepatitis, serum tests for Hepatitis E were performed. Hepatitis E virus RNA was detected in blood and stools. After six months the virus was still detected. Ribavirin treatment was initiated with normalization of the serum aminotransferases and sustained virology response was achieved.

Hepatocellular carcinoma (HCC) recurrence following liver transplantation is associated to bad prognosis. We retrospectively analyzed the data of 95 patients who underwent liver transplantation for HCC. Recurrence rate and variables associated with recurrence were reviewed. According to the findings on the explanted livers they were divided in two groups: Milan (M) 67% and non-Milan (NM) 33%. Global recurrence rate, and M-group and NM-group recurrence rates were 19%; 12% and 32%, respectively (P = 0.001). Although in the univariate analysis we found some factors associated to recurrence (hemocromathosis, year of transplant, bilobar distribution, vascular invasion and previous chemoembolization), they were not independent predictors of recurrence in the multivariate analysis. Actuarial survival in cirrhotic patients with and without HCC at 1, 3 and 5 years was 86% and 91% (NS), 77% and 88% (NS), and 67% and 86% (P = 0.002), respectively; whereas actuarial survival of the M and NM groups was 86% and 71%; 82% and 61%, and 78% and 58%, respectively (P = 0.02). We had a satisfactory five-year global survival in our series even though one third of our patients grafted for HCC were outside Milan criteria.

Two cases of hepatitis E that were assisted in our Unit of Hepatology and Liver Transplantation are described in this article. The first patient had prior hepatic involvement and therefore a more severe course, whereas the second case, with normal liver function, only developed a self-limited acute hepatitis.
