- Hepatic immune-mediatedadverseeffects of immune checkpoint inhibitors: analysis of real-life experiencePublication . Silva, Joana; Falcão, Daniela; Cardoso, Cláudia; Pires, Ana Luísa; Araújo, António; Castro-Poças, FernandoIntroduction and objectives: Immune Checkpoint Inhibitors (ICI) have shifted the paradigm of cancer therapy treatment. Despite their efficacy, ICIs may induce immune-related adverse events (irAE), which can affect various organs, namely the liver. This study intends to perform a comprehensive clinical description of the hepatic irAEs associated with ICI in a Portuguese population of a tertiary hospital centre. Materials and methods: A retrospective analysis of patients who developed immune-mediated liver injury (IMLI), among a cohort of patients treated with ICIs between March 15th of 2015 and December 15th of 2019 in a tertiary hospital. We used both Common Terminology Criteria for Adverse Events (CTCAE) and Drug-Induced Liver Injury Network (DILIN) criteria to define liver injury. Results: Among 151 patients, eight (5.3%) patients developed liver injury grade ≥3, of which five had hepatic metastasis. As such, only 3 cases were classified as IMLI. All IMLI presented with cholestasis pattern; the median duration from ICI initiation to IMLI was 84 days and/or 4 ICI cycles; one patient registered IMLI one month after nivolumab suspension; all were treated with steroids and one was successfully submitted to ICI re-challenge; a favourable outcome was seen in all patients; the median time to hepatic biochemistries normalization was 150 days. Among 10 patients with previous hepatic conditions, only one developed liver injury grade 2. Conclusions: Clinically significant ICI-related hepatotoxicity was uncommon; Immune-mediated liver injury may present a cholestatic pattern predominance. There was a low rate of liver injury of any kind in patients with previous hepatic disease while on ICI.
- Long-Term Follow-Up of Advanced Liver Disease after Sustained Virological Response to Treatment of Hepatitis C with Direct-Acting Antivirals: Outcomes from a Real-World Portuguese CohortPublication . Pereira Guedes, Tiago; Fragoso, Pedro; Lemos, Carolina; Garrido, Mónica; Silva, Joana; Falcão, Daniela; Maia, Luís; Moreira, Teresa; Manuel Ferreira, José; Pedroto, IsabelBackground: Direct-acting antivirals (DAA) have revolutionized hepatitis C treatment, with high sustained virological response (SVR) rates reported, even in historically difficult-to-treat groups. SVR is associated with a decreased risk of hepatocellular carcinoma (HCC), need for transplantation, and overall and liver-related mortality. Data from real-life cohorts on the medium- to long-term outcomes of patients with advanced liver disease and DAA-induced SVR are still missing. Objectives: To report and analyze the long-term outcomes of DAA-induced SVR in a real-life cohort of patients with advanced liver disease. Method: In this retrospective, longitudinal, single-center study, we collected data from patients with chronic hepatitis C infection and advanced liver disease (cirrhosis or advanced fibrosis) that had initiated DAA treatment between February 2015 and January 2017. Results: A total of 237 patients were included. A treatment completion rate of 98.7% and an SVR rate of 97.8% (intention to treat: 96.6%) were found. Of the 229 patients with SVR, 67.2% were cirrhotic (64.2% Child-Pugh class A; 3.1% Child-Pugh class B) and 32.8% had stage F3 fibrosis, with an average follow-up of 28 months. The overall mortality rate was 19/1,000 person-years and the liver-related mortality rate was 9.5/1,000 person-years. The hepatic decompensation incidence rate was 25/1,000 person-years and the HCC incidence rate was 11.6/1,000 person-years. There was a sustained increase in serum platelet values during up to 2 years of follow-up. A history of pretreatment decompensation and baseline platelet and albumin values were significantly associated with the occurrence of adverse liver events after the end of treatment. Conclusions: A DAA-induced SVR remains durable and is associated with an excellent clinical prognosis in patients with compensated advanced liver disease and with improvement or disease stabilization in decompensated patients. SVR is associated with a low risk of - yet does not prevent - HCC occurrence or disease progression, especially in the presence of other causes of liver injury. It is recommended that these patients be kept under surveillance.
