Real-life effectiveness of sofosbuvir/velpatasvir/voxilaprevir in hepatitis C patients previously treated with sofosbuvir/velpatasvir or glecaprevir/pibrentasvir.

BACKGROUND: Sofosbuvir, velpatasvir and voxilaprevir (SOF/VEL/VOX) is the recommended rescue therapy for patients with chronic hepatitis C infection who fail direct-acting antivirals (DAAs). Data are limited on the effectiveness of this treatment after the current first-line therapies. Our aim was to analyse the effectiveness and safety of SOF/VEL/VOX among patients failing sofosbuvir/velpatasvir (SOF/VEL) or glecaprevir/pibrentasvir (GLE/PIB). METHODS: Retrospective multicentre study (26 Spanish hospitals), including chronic hepatitis C patients unsuccessfully treated with SOF/VEL or GLE/PIB, and retreated with SOF/VEL/VOX ± ribavirin for 12 weeks between December 2017 and December 2022. RESULTS: In total, 142 patients included: 100 (70.4%) had failed SOF/VEL and 42 (29.6%) GLE/PIB. Patients were mainly men (84.5%), White (93.9%), with hepatitis C virus genotype (GT) 3 (49.6%) and 47.2% had liver cirrhosis. Sustained virological response (SVR) was evaluated in 132 patients who completed SOF/VEL/VOX and were followed 12 weeks after end of treatment; 117 (88.6%) achieved SVR. There were no significant differences in SVR rates according to initial DAA treatment (SOF/VEL 87.9% vs. GLE/PIB 90.2%, p = 0.8), cirrhosis (no cirrhosis 90% vs. cirrhosis 87.1%, p = 0.6) or GT3 infection (non-GT3 91.9% vs. GT3 85.5%, p = 0.3). However, when considering the concurrent presence of SOF/VEL treatment, cirrhosis and GT3 infection, SVR rates dropped to 82.8%. Ribavirin was added in 8 (6%) patients, all achieved SVR. CONCLUSION: SOF/VEL/VOX is an effective rescue therapy for failures to SOF/VEL or GLE/PIB, with an SVR of 88.6%. Factors previously linked to lower SVR rates, such as GT3 infection, cirrhosis and first-line therapy with SOF/VEL were not associated with lower SVRs.

An international, multicenter, survey-based analysis of practice and management of acute liver failure.

INTRODUCTION: Acute liver failure (ALF) is an acute liver dysfunction with coagulopathy and hepatic encephalopathy in a patient with no known liver disease. As ALF is rare and large clinical trials are lacking, the level of evidence regarding its management is low-moderate, favoring heterogeneous clinical practice. In this international multicenter survey study, we aimed to investigate the current practice and management of patients with ALF. METHODS: An online survey targeting physicians who care for patients with ALF was developed by the International Liver Transplantation Society ALF Special-Interest Group. The survey focused on management and liver transplantation (LT) practices of ALF. Survey questions were summarized overall and by geographic region. RESULTS: A total of 267 physicians completed the survey with a survey response rate of 21.36%. Centers from all continents were represented. More than 90% of physicians were specialized in either transplant hepatology/surgery or anesthesiology/critical care. Two hundred and fifty-two (94.4%) respondents' institutions offered LT. A total of 76.8% of respondents' centers had a dedicated liver- or transplant- intensive care unit (p<0.001). Median time to LT was within 48 hours in 12.7% of respondents' centers, 72 hours in 35.6%, one week in 37.6%, and more than one week in 9.6% (p<0.001). Deceased-donor liver graft (49.6%) was the most common type of graft offered. For consideration of LT, 84.8% of physicians used King's College Criteria and 41.6% used Clichy Criteria. Significant differences were observed between Asia, Europe, and North America for offering LT, number of LTs performed, volume of ALF patients, admission to a dedicated intensive care unit, median time to LT, type of liver graft, monitoring hepatic encephalopathy and intracranial pressure, management of coagulopathy, and utilization of different criteria for LT. DISCUSSION: In our study, we observed significant geographic differences in the practice and management of ALF. As ALF is rare multicenter studies are valuable to identify global practice.

CA125 como nuevo biomarcador en pacientes con circulación de Fontan / CA125: a new biomarker in patients with Fontan circulation

Introducción y objetivos Los pacientes con circulación de Fontan (CF) presentan una gran incidencia de complicaciones y ningún biomarcador estratifica el riesgo. El objetivo es analizar la asociación de biomarcadores con un perfil clínico de disfunción de la CF, incluyendo por primera vez el antígeno carbohidrato 125 (CA125), y proponer una estimación del riesgo basada en la combinación de biomarcadores. Métodos Estudio transversal de adultos con CF. Se consideró perfil clínico desfavorable el combinado de insuficiencia cardiaca, arritmias auriculares, fístulas venovenosas, enteropatía pierdeproteínas o bronquitis plástica. Se analizaron variables clínicas y analíticas, incluidos CA125, NT-proBNP, función renal y hepática y amplitud de distribución eritrocitaria (ADE). Se realizó un estudio univariado y multivariado de la relación de dichas complicaciones clínicas y curvas ROC para obtener puntos de corte. Resultados Se incluyó a 56 pacientes (media de edad, 27,4±7,8 años). El 34% tenía un perfil clínico desfavorable, con valores de CA125 significativamente mayores (30,1 frente a 12,6 UI/ml; p=0,001). LnCA125 (OR=5,1; IC95%, 1,2-22), ADE (OR=1,8; IC95%, 1,1-3.1) y FIB4 (OR=38; IC95%, 1,7-855) se asociaron con un perfil de disfunción clínica. Los puntos de corte fueron CA125 ≥ 20 U/ml, FIB4 ≥ 0,75 y ADE ≥ 14,5%, y la probabilidad de un perfil clínico desfavorable fue del 81% con 2 o más biomarcadores elevados. Conclusiones El aumento de CA125 se asocia con mayor prevalencia de complicaciones en pacientes con CF. Los valores de CA125 ≥ 20 U/ml, FIB4 ≥ 0,75 y ADE ≥ 14,5% identifican con alta probabilidad fracaso clínico de la CF. (AU)

Introduction and objectives Patients with Fontan circulation (FC) have a high incidence of clinical complications. However, no biomarker is able to accurately stratify risk. The aim of this study was to analyze the relationship between biomarkers and clinical complications, including carbohydrate antigen 125 (CA125) for the first time, and to propose a risk estimation based on a combination of biomarkers. Methods Cross-sectional study of patients with FC. The clinical endpoint was the combination of heart failure, atrial arrhythmias, veno-venous fistulae, protein-losing enteropathy, or plastic bronchitis. Demographic, clinical, and laboratory variables were analyzed, including CA125, NT-proBNP, renal and liver function, and red cell distribution width (RDW). We performed univariate and multivariate analyses of the relationship between these variables and the composite endpoint. Cutoff values were calculated by ROC curves. Results We included 56 patients (27.4±7.8 years). A total of 34% showed the composite endpoint, with significantly higher CA125 levels (30.1 IU/mL vs 12.6 IU/mL; P=.001). In the multivariate model, the biomarkers related to the endpoint were LnCA125 (OR, 5.1; 95%CI, 1.2-22), RDW (OR, 1.8; 95%CI, 1.1-3.1), and FIB4 (OR, 38, 95%CI, 1.7-855). The cutoff points were CA125 ≥ 20 U/mL, FIB4 ≥ 0.75, and RDW ≥ 14.5%, and the probability of the occurrence of the endpoint was 81% if ≥ 2 biomarkers were elevated. Conclusions CA125 elevation is associated with a higher prevalence of complications in patients with Fontan-type circulation. CA125 levels ≥ 20U/mL, FIB4 ≥ 0.75 and RDW ≥ 14.5% identify with a high probability the clinical failure of FC. (AU)

Características e impacto del sexo en una cohorte de pacientes con colangitis esclerosante primaria: experiencia de un centro trasplantador de la cuenca mediterránea / Characteristics and impact of sex in a cohort of patients with primary sclerosing cholangitis: Experience of a transplant center in the Mediterranean basin

Introducción y objetivos: La colangitis esclerosante primaria (CEP) es una enfermedad hepática colestásica rara, que típicamente afecta a varones de mediana edad con colitis ulcerosa (CU). No obstante, estudios recientes apuntan a cambios epidemiológicos. Nuestro objetivo es determinar si la epidemiología, presentación clínica y curso evolutivo de pacientes con CEP seguidos en un centro de referencia se asemejan a lo descrito en la literatura. Pacientes y métodos: Búsqueda retrospectiva de pacientes con diagnóstico de CEP atendidos en nuestro centro entre los años 2000 y 2019.Resultados: Cohorte de 55 pacientes (media de edad: 37 años), el 44% mujeres, afectos de CEP, el 79% de ducto grande. Casi dos tercios fueron diagnosticados a partir de 2011. En el momento del diagnóstico, un 63% de los pacientes se encontraba asintomático. La mediana de tiempo desde la sospecha hasta el diagnóstico fue de 2 años. Un 34% desarrolló cirrosis en el seguimiento, y un 25% requirió trasplante hepático (TH) tras una media de tiempo de 7 años; entre estos, la enfermedad recurrió en un 46%. Un 45% presentaba una enfermedad inflamatoria intestinal (EII), sobre todo CU. Si bien no se alcanzó significación estadística, la CEP en mujeres se caracterizó por mayor tasa de presentación asintomática, mayor asociación con CU frente a otras formas de EII, así como cirrosis al diagnóstico y necesidad de TH con mayor frecuencia que los varones.Conclusiones: La epidemiología de la CEP está cambiando. El número de mujeres afectas es mayor al descrito previamente, objetivándose un aumento reciente de la incidencia. Podrían existir diferencias entre sexos en la forma de presentación y evolución que deberán confirmarse en estudios posteriores. (AU)

Background and aims: Primary sclerosing cholangitis (PSC) is a rare cholestatic liver disease that typically affects middle-aged men with ulcerative colitis (UC). However, recent studies point out to epidemiological changes. Our aim was to determine if the epidemiology, clinical course and outcome of patients with PSC followed at a reference hepatology center resemble what is described in the literature. Patients and method: Retrospective search of patients with a diagnosis of PSC treated in our center between 2000 and 2019.Results: Cohort of 55 patients (mean age: 37 years), 44% women. Most were large duct type (79%). Most diagnoses were made after 2011. At time of diagnosis, 63% of patients were asymptomatic. The median time from suspicion to diagnosis was 2 years. After a mean follow-up time of 7 years, one third developed cirrhosis, and 25% required liver transplantation (LT); among these, the disease recurred in almost half. Inflammatory bowel disease (IBD) was present in 45%, especially UC. Although statistical significance was not reached, PSC in women was characterized by higher rate of asymptomatic presentation and more frequent association with UC versus other forms of IBD. Women also had more frequently cirrhosis at diagnosis and required LT more often than men.Conclusion: The epidemiology of PSC is changing. The number of women affected is greater than what was expected from the literature, with a recent increase in incidence. There seems to be differences between sexes in the form of presentation and disease course that should be confirmed in subsequent studies. (AU)
