The effectiveness of daclatasvir based therapy in European patients with chronic hepatitis C and advanced liver disease

Daclatasvir; Eficàcia; Hepatitis CDaclatasvir; Eficacia; Hepatitis CDaclatasvir; Effectiveness; Hepatitis CBackground There is limited evidence for the effectiveness of daclatasvir in patients whose hepatitis C threatens their life expectancy. The Named Patient Program in Europe included patients with advanced chronic hepatitis C, a life expectancy of less than 12 months and no other treatment options. Methods A retrospective multi-country cohort of patients with chronic hepatitis C who received daclatasvir as part of the Named Patient Program in Austria, Denmark, Spain, Sweden, Switzerland and the United Kingdom. Treatment response was defined as a sustained virologic response (unquantifiable hepatitis C RNA) at 12 weeks post treatment. We summarised the characteristics of the patients in this cohort and estimated the rate of sustained virologic response for patients receiving daclatasvir and sofosbuvir with or without ribavirin using hierarchical Bayesian modelling. Results The 249 patients included had a median age of 56 years; most were male (78%), hepatitis C genotype 1 (75%), treatment experienced (65%) and with decompensated cirrhosis (59%). Many had had a liver transplant before receiving daclatasvir (40%). Of the 249 patients, 242 patients received daclatasvir and sofosbuvir and either reached 12 weeks post treatment or died during (n = 9) or after treatment (n = 4) or were lost to follow up during treatment (n = 1). The estimated rate of sustained virologic response at 12 weeks post treatment was 87% (95% credible interval 75 to 94%) for previously treated genotype 1 patients with decompensated cirrhosis. Conclusions Daclatasvir with sofosbuvir is an effective treatment in clinical practice for hepatitis C genotype 1 patients with decompensated cirrhosis.This work was supported by BMS

Spontaneous portosystemic shunt embolization in liver transplant recipients with recurrent hepatic encephalopathy

Angiogenesis; Portal hypertension; Collateral vesselsAngiogénesis; Hipertensión portal; Vasos colateralesAngiogènesi; Hipertensió portal; Vasos col·lateralsIntroduction and objectives Spontaneous portosystemic shunts (SPSS) are a common cause of recurrent hepatic encephalopathy (HE). Shunt occlusion is an effective and safe procedure when performed in patients with cirrhosis and preserved liver function. We aimed to describe our experience with SPSS embolization after liver transplantation (LT). Patients We identified five patients who underwent SPSS embolization after LT. Clinical, biochemical and technical procedure data were collected. Results At presentation, all patients had developed graft cirrhosis and HE after LT. Median Model for End-stage Liver Disease (MELD) at embolization was 9 (range 7-12), median Child-Pugh was 8 (range 7-9). Splenorenal and mesocaval shunt were the most frequent types of SPSS found. Three patients have been completely free of HE. Of the two patients who had HE recurrence after embolization, one patient had two episodes of HE which was controlled well with medications. The other patient required three embolizations because of recurrent HE. Median follow-up was 4.4 years (range 1.0-5.0) and MELD score at last follow up was 13 (range 10-18) and median Child-Pugh score B, 7 points (range 5-12). Conclusions SPSS can be considered as a cause of HE after LT. SPSS embolization is feasible and safe in LT recipients.Isabel Campos-Varela's research activity is funded by grant PI19/00330, funded by Instituto de Salud Carlos III and co-funded by European Union (ERDF/ESF) - A way to build Europe.

High intrapatient variability of tacrolimus exposure associated with poorer outcomes in liver transplantation

Liver transplantation; Tacrolimus; Liver diseasesTrasplante de hígado; Tacrolimús; Enfermedades del hígadoTrasplantament hepàtic; Tacrolimús; Malalties del fetgeTacrolimus (TAC) is a dose-dependent immunosuppressor with considerable intrapatient variability (IPV) in its pharmacokinetics. The aim of this work is to ascertain the association between TAC IPV at 6 months after liver transplantation (LT) and patient outcome. This single-center cohort study retrospectively analyzed adult patients who underwent transplantation from 2015 to 2019 who survived the first 6 months with a functioning graft. The primary end point was the patient’s probability of death and the secondary outcome was the loss of renal function between month 6 and the last follow-up. TAC IPV was estimated by calculating the coefficient of variation (CV) of the dose-corrected concentration (C0/D) between the third and sixth months post-LT. Of the 140 patients who underwent LT included in the study, the low-variability group (C0/D CV < 27%) comprised 105 patients and the high-variability group (C0/D CV ≥ 27%) 35 patients. One-, 3-, and 5-year patient survival rates were 100%, 82%, and 72% in the high-variability group versus 100%, 97%, and 93% in the low-variability group, respectively (p = 0.005). Moreover, significant impaired renal function was observed in the high-variability group at 1 year (69 ± 16 ml/min/1.73 m2 vs. 78 ± 16 ml/min/1.73 m2, p = 0.004) and at 2 years post-LT (69 ± 17 ml/min/1.73 m2 vs. 77 ± 15 ml/min/1.73 m2, p = 0.03). High C0/D CV 3–6 months remained independently associated with worse survival (hazard ratio = 3.57, 95% CI = 1.32–9.67, p = 0.012) and loss of renal function (odds ratio = 3.47, 95% CI = 1.30–9.20, p = 0.01). Therefore, high IPV between the third and sixth months appears to be an early and independent predictor of patients with poorer liver transplant outcomes.Isabel Campos-Varela’s research activity is funded by grant PI19/00330 from Instituto de Salud Carlos III.

Non-Invasive Tests of Liver Fibrosis Help in Predicting the Development of Hepatocellular Carcinoma among Patients with NAFLD

Carcinoma hepatocelular; Elastografía transitoriaCarcinoma hepatocel·lular; Elastografia transitòriaHepatocellular carcinoma; Transient elastographyBackground: The potential role of non-invasive tests (NITs) for liver fibrosis for hepatocellular carcinoma (HCC) prediction remains poorly known. Methods: Retrospective analysis of a NAFLD cohort from a single university hospital in Barcelona, Spain. Incidence rates and cumulative incidence for the overall cohort, as well as cirrhotic and non-cirrhotic patients were calculated. Logistic regression analyses were carried out to investigate risk factors of HCC. Results: From the entire cohort of 1040 patients, 996 patients (95.8%) were analyzed, in whom 35 cases of HCC were detected, of which 26 (72.4%) HCC incident cases were newly diagnosed during a median follow-up of 2.5 (1.9–3.6) years. Two-hundred and thirty-one (23.2%) were cirrhotic at baseline. With the exception of 2 (7.7%) cases of HCC, the rest were diagnosed in cirrhotic patients. Overall HCC cumulative incidence was 9.49 (95% CI 6.4–13.9) per 1000 person-years. The incidence rate for cirrhotic patients was 41.2 (95% CI 27.6–61.6) per 1000 person-years and 0.93 (95% CI 0.23–3.7) per 1000 person-years for patients without cirrhosis. Overall mortality was significantly higher amongst patients with HCC (4.4% vs. 30.8%, p < 0.001). In patients with available liver biopsy (n = 249, 25%), advanced fibrosis (F3–F4) was significantly associated with higher HCC incidence, but not steatosis, lobular inflammation, nor ballooning. In the overall cohort, FIB-4 ≥1.3 (HR 8.46, 95% CI 1.06–67.4, p = 0.044) and older age (HR 1.06, 95% CI 1.01–1.11, p = 0.025) were associated with increasing risk of HCC over time, whereas in cirrhotic patients predictors of HCC included decreasing values of albumin (HR 0.34, 95% CI 0.13–0.87, p = 0.024), platelets (HR 0.98, 95% CI 0.98–0.99, p = 0.001), and increasing values of liver stiffness (HR 1.03, 95% CI 1.00–1.06, p = 0.016). Conclusions: In a Spanish cohort of NAFLD patients, HCC was rare in non-cirrhotic patients. NITs might play a relevant role at predicting HCC.The study was conducted in accordance with the Declaration of Helsinki and approved by the Vall d’Hebron University Hospital Campus Institutional Review Board (study protocol code PR(AG)626/2021)
