ABSTRACT

INTRODUCTION: Patient blood management (PBM) adherence in clinical practice is unclear. This real-world practice study assessed the management of patients with gastrointestinal (GI) bleeding after the implementation of the PBM strategy. METHODS: This was a nationwide multicenter and prospective study involving consecutive adults with GI bleeding between March 2019 and March 2021. Patients were examined according to hemoglobin (Hb) level at admission (<7 g/dl, n = 93; 7-8 g/dl, n = 47; 8-9 g/dl, n = 61; and >9 g/dl, n = 249). Study outcomes measures were morbidity and mortality during hospitalization and at 3- and 6-month follow-up. Appropriate anemia or iron deficiency management was considered when adherence to PBM policy was higher than 75%. RESULTS: A total of 450 patients (57.6% men, median age: 74 years, interquartile range: 63-82) were included. Overall, 55.1% and 59.3% of patients received transfusion and iron supplementation, respectively. The rates of appropriate transfusion and iron supplementation adherence were 90.9% (range: 86.9-93.5%, P = 0.109) and 81.8% (range: 78.5-85.1%, P = 0.041), depending on Hb level, respectively. No associations were observed between adherence to the PBM strategy and length of stay (P = 0.263) or risk of further bleeding (P = 0.742). Patients who were transfused [hazard ratio (HR): 0.79, 95% confidence interval (CI): 0.27-0.85] and iron supplemented (HR: 0.91, 95% CI: 0.38-1.41), however, appropriately achieved a lower risk of death. Age (HR: 1.12, 95% CI: 1.12-1.25) and further bleeding (HR: 39.08, 95% CI: 4.01-181.24) were poor prognostic factors. No serious adverse events were reported. CONCLUSIONS: In this nationwide study, there is a high level of adherence and safety of PBM for the treatment of GI bleeding. Adherence to the PBM strategy improved outcomes in patients with GI bleeding.

ABSTRACT

Background/Aim: Atezolizumab/bevacizumab (atez/bev) has been established as first-line systemic treatment for hepatocellular carcinoma (HCC). However, concerns regarding safety and efficacy have been raised, and no biomarkers to predict response have yet been identified. We aimed to evaluate the real-life experience of atez/bev in a Spanish tertiary hospital and identify factors associated with overall survival (OS). Patients and Methods: A prospective study of consecutive patients with HCC treated with atez/bev was conducted from December 2020 to December 2022. Efficacy was assessed through OS and progression-free survival (PFS), whereas safety was evaluated based on adverse events (AE). Twenty-three patients were included; 91% were males with a mean of 70 years. Thirteen patients were classified as having BCLC-C. Results: The median treatment duration was 126 days (range=567). Median OS was 381 days (95%CI=205-557) with a cumulative probability of death of 13%, 30%, and 49% at 3, 6 and 12-month follow-up, respectively. The only factor associated with OS was the ALBI score (HR=5.03; 95%CI=1.3-19.1), which showed an AUROC of 0.906 (95%CI=0.78-1.00) for the risk of death at 18 months follow up. Median PFS was 141 days (95%CI=110-172). Twenty (86.9%) patients experienced AE, which in nine (39.1%) cases led to the definitive discontinuation of the treatment, four of them (17.4%) due to an AE grade 5. Conclusion: The initial experience with atez/bev at our center demonstrated poorer outcomes compared to the original trial (IMbrave150). A careful assessment of the ALBI score may serve as a crucial factor in the selection of systemic treatment for patients with HCC.

ABSTRACT

BACKGROUND AND AIMS: It has been described that recompensation can improve prognosis in patients with cirrhosis. However, recompensation after transjugular intrahepatic portosystemic shunt (TIPS) has not been studied. We evaluated the impact of recompensation after TIPS on the risk of hepatocellular carcinoma (HCC) and death, and we compared it with compensated cirrhosis patients. METHODS: An observational study of consecutive patients with cirrhosis undergoing TIPS between 2008 and 2022 was performed. Baveno VII definition of recompensation was used including patients with or without diuretics/Hepatic encephalopathy prophylaxis. A prospective cohort of consecutive compensated cirrhosis patients was used for comparison. RESULTS: Overall, 208 patients with cirrhosis were included, 92 compensated and 116 decompensated who underwent TIPS. After 1 year, 24% achieved recompensation. Liver function (MELD 12 ± 5 vs. 15 ± 6; p = .049), LDL-cholesterol (97 mg/dL vs. 76 mg/dL, p = .018), white cell count (7.96 × 109/dL vs. 6.24 × 109/dL, p = .039) and platelets (129 × 109/dL vs. 101 × 109/dL, p = .039) were associated with recompensation. Recompensation was associated with a reduction in the risk of HCC (p = .020). Multivariable analysis showed that this risk was significantly higher in non-recompensated patients (p = .003) but no differences were observed in recompensated compared with compensated patients (p = .816). Similarly, decompensated patients presented lower survival rates (p = .011), while no differences were observed between recompensated and compensated patients (p = .677). CONCLUSIONS: Recompensation after TIPS has a clear impact on the incidence of HCC and death, with a similar prognosis than patients with compensated cirrhosis. Liver function is associated with recompensation, suggesting the importance of considering early TIPS in patients with indication.

ABSTRACT

Ammonia is a product of amino acid metabolism that accumulates in the blood of patients with cirrhosis and plays a pivotal role in the pathogenesis of hepatic encephalopathy (HE). Despite being one of the main drivers of brain dysfunction, for many years international societies stated that increased blood ammonia does not add any diagnostic, staging, or prognostic value for HE in patients with cirrhosis. Nonetheless, in the last decades, evidence is emerging that supports the utility of ammonia for risk stratification, but its role in guiding HE diagnosis, staging, and treatment is unclear and there is equipoise in its use in clinical practice. This review provides the latest evidence on the value of ammonia as a biomarker in patients with cirrhosis. Although correct measurement of ammonia requires disciplined sample collection, it provides extremely useful clinical guidance for the diagnosis of HE, offers prognostic information, and it defines a therapeutic target.

ABSTRACT

INTRODUCTION: Biological therapies used for the treatment of inflammatory bowel disease (IBD) have shown to be effective and safe, although these results were obtained from studies involving mostly a young population, who are generally included in clinical trials. The aim of our study was to determine the efficacy and safety of the different biological treatments in the elderly population. METHODS: Multicenter study was carried out in the GETECCU group. Patients diagnosed with IBD and aged over 65 years at the time of initiating biological therapy (infliximab, adalimumab, golimumab, ustekinumab or vedolizumab) were retrospectively included. Among the patients included, clinical response was assessed after drug induction (12 weeks of treatment) and at 52 weeks. Patients' colonoscopy data in week 52 were assessment, where available. Regarding complications, development of oncological events during follow-up and infectious processes occurring during biological treatment were collected (excluding bowel infection by cytomegalovirus). RESULTS: A total of 1090 patients were included. After induction, at approximately 12-14 weeks of treatment, 419 patients (39.6%) were in clinical remission, 502 patients (47.4%) had responded without remission and 137 patients (12.9%) had no response. At 52 weeks of treatment 442 patients (57.1%) had achieved clinical remission, 249 patients had responded without remission (32.2%) and 53 patients had no response to the treatment (6.8%). Before 52 weeks, 129 patients (14.8%) had discontinued treatment due to inefficacy, this being significantly higher (p<0.0001) for Golimumab - 9 patients (37.5%) - compared to the other biological treatments analyzed. With respect to tumor development, an oncological event was observed in 74 patients (6.9%): 30 patients (8%) on infliximab, 23 (7.14%) on adalimumab, 3 (11.1%) on golimumab, 10 (6.4%) on ustekinumab, and 8 (3.8%) on vedolizumab. The incidence was significantly lower (p=0.04) for the vedolizumab group compared to other treatments. As regards infections, these occurred in 160 patients during treatment (14.9%), with no differences between the different biologicals used (p=0.61): 61 patients (19.4%) on infliximab, 39 (12.5%) on adalimumab, 5 (17.8%) on golimumab, 22 (14.1%) on ustekinumab, and 34 (16.5%) on vedolizumab. CONCLUSIONS: Biological drug therapies have response rates in elderly patients similar to those described in the general population, Golimumab was the drug that was discontinued most frequently due to inefficacy. In our experience, tumor development was more frequent in patients who used anti-TNF therapies compared to other targets, although its incidence was generally low and that this is in line with younger patients based on previous literature.

ABSTRACT

BACKGROUND: Rifaximin is a non-reabsorbable antibiotic which acts at gut level, and improves cognition and inflammatory parameters in minimal hepatic encephalopathy (MHE) patients, but not all patients show the same level of response. This study aims to assess brain activity, both within and between brain networks, following rifaximin treatment, considering the differences between response groups as well. METHODS: Twenty-two healthy controls and 53 patients with cirrhosis (22 without and 31 with MHE, diagnosed by Psychometric Hepatic Encephalopathy Score, PHES) performed psychometric, attention and coordination tests, and blood inflammatory parameters were measured. Resting-state functional magnetic resonance imaging (fMRI) acquisitions were performed on controls and MHE patients. Eighteen MHE patients underwent a rifaximin treatment for 6 months, after which all measures were repeated. fMRI images were analysed and changes after treatment were assessed. RESULTS: After rifaximin treatment, 13 patients improved their PHES score (Responder patients) while 5 did not (Non-responder patients). No significant decrease in blood ammonia was observed after rifaximin treatment, but there was a decrease in plasma inflammatory cytokines in responder patients. A global effect of rifaximin was detected on the sensorimotor and fronto-parietal networks. Responder patients showed a relative increase of thalamic network connectivity in comparison to non-responder patients. Before treatment, responder and non-responder patients showed connectivity differences in basal ganglia network. The connection of the sensorimotor and thalamic networks between them and with other networks suffered changes after treatment. These connections between networks mostly decreased after treatment. All changes and differences showed a significant level of correlation with the performance of psychometric tests and the blood levels of inflammatory biomarkers. CONCLUSIONS: There was an improvement of the communication between executive, motor and attention-related brain areas, and their functional independence following rifaximin treatment. Patients who respond also show a less deteriorated connection involved in these functions before treatment. Results suggest that the improved inflammatory state of MHE patients, following rifaximin treatment would favour the observed changes in brain function and enhanced cognitive performance.

ABSTRACT

Background: Loss-of-response and adverse events (AE) to biologics have been linked to HLA-DQA1*05 allele. However, the clinical factors or biologic used may influence treatment duration. Our objective was to evaluate the influence of clinical and therapeutic factors, along with HLA, in biological treatment discontinuation. Methods: A retrospective study of consecutive IBD patients treated with biologics between 2007 and 2011 was performed. Main outcome was treatment discontinuation due to primary non-response (PNR), secondary loss of response (SLR) or AE. HLA-DQA1 genotyping was done in all patients. Regression analyses were used to assess risk factors of treatment discontinuation. Results: One hundred fifty patients (61% male) with 312 biologic treatments were included. 147 (47%) were discontinued with a cumulative probability of 30%, 41% and 56% at 1, 2 and 5 years. The use of infliximab (p=0.006) and articular manifestations (p<0.05) were associated with treatment discontinuation. Considering cause of withdrawal, Ulcerative Colitis (UC) had a higher proportion of PNR (HR=4.99; 95% CI=1.71–14.63; p=0.003), SLR was higher if biologics had been indicated due to disease flare (HR=2.32; 95% CI=1.05–5.09; p=0.037) while AE were greater with infliximab (HR=2.46; 95% CI=1.48–4.08; p<0.001) or spondylitis (HR=2.46; 95% CI=1.78–6.89; p<0.001). According to the biological drug, HLA-DQA1*05 with adalimumab showed more SLR in cases with Crohn's disease (HR=3.49; 95% CI=1.39–8,78; p=0.008) or without concomitant immunomodulator (HR=2.8; 95% CI=1.1–6.93; p=0.026). Conclusions: HLA-DQ A1*05 was relevant in SLR of IBD patients treated with adalimumab without immunosupression. In patients treated with other biologics, clinical factors were more important for treatment interruption, mainly extensive UC or extraintestinal manifestations and having indicated the biologic for flare.

Introducción: Estudios previos han observado una asociación entre el HLA-DQA1*05 y la pérdida de respuesta a biológicos y el desarrollo de efectos adversos (EA). Hay factores clínicos y biológicos que podrían influir en la duración del tratamiento. El objetivo del estudio fue evaluar la influencia del HLA, de factores clínicos y terapéuticos en la interrupción del tratamiento biológico. Métodos: Se realizó un estudio retrospectivo de pacientes con enfermedad inflamatoria intestinal (EII) tratados con biológicos entre 2007 y 2011. Los principales eventos analizados fueron la suspensión del tratamiento por fallo de respuesta primaria (PRP), secundaria (PRS) o EA. Se realizó un tipaje del HLA-DQA1*05 y se evaluaron los factores de riesgo de interrupción del tratamiento mediante un análisis de regresión logística. Resultados: Se incluyeron 150 pacientes y 312 tratamientos, de los cuales se suspendieron 147 (47%) en el seguimiento. El infliximab (p=0,006) y las manifestaciones articulares (p<0,05) se relacionaron con la interrupción del tratamiento. La colitis ulcerosa (CU) presentó mayor PRP (HR: 4,99; IC 95%: 1,71-14,63; p=0,003), el brote como indicación de tratamiento se asoció a más PRS (HR: 2,32; IC 95%: 1,05-5,09; p=0,037); el uso de infliximab (HR: 2,46; IC 95%: 1,48-4,08; p<0,001) y la espondilitis (HR: 2,46; IC 95%: 1,78-6,89; p<0,001) a la suspensión por EA. El HLA-DQA1*05 fue un factor de riesgo de PRS en los pacientes tratados con adalimumab (ADA) con enfermedad de Crohn (HR: 3,49; IC 95%: 1,39-8,78; p=0,008) o con EII sin inmunosupresor asociado (HR: 2,8; IC 95%: 1,1-6,93; p=0,026). Conclusiones: El HLA-DQA1*05 se asoció al cese del tratamiento con ADA por PRS en los pacientes con EII sin inmunosupresor asociado. Respecto a otros biológicos, la suspensión se debió más a factores como la CU, las manifestaciones articulares y la indicación para remisión de brote intestinal. (AU)

ABSTRACT

BACKGROUND: Vaccine hesitancy and lack of access remain major issues in disseminating COVID-19 vaccination to liver patients globally. Factors predicting poor response to vaccination and risk of breakthrough infection are important data to target booster vaccine programs. The primary aim of the current study was to measure humoral responses to 2 doses of COVID-19 vaccine. Secondary aims included the determination of factors predicting breakthrough infection. METHODS: COVID-19 vaccination and Biomarkers in cirrhosis And post-Liver Transplantation is a prospective, multicenter, observational case-control study. Participants were recruited at 4-10 weeks following first and second vaccine doses in cirrhosis [n = 325; 94% messenger RNA (mRNA) and 6% viral vaccine], autoimmune liver disease (AILD) (n = 120; 77% mRNA and 23% viral vaccine), post-liver transplant (LT) (n = 146; 96% mRNA and 3% viral vaccine), and healthy controls (n = 51; 72% mRNA, 24% viral and 4% heterologous combination). Serological end points were measured, and data regarding breakthrough SARS-CoV-2 infection were collected. RESULTS: After adjusting by age, sex, and time of sample collection, anti-Spike IgG levels were the lowest in post-LT patients compared to cirrhosis (p < 0.0001), AILD (p < 0.0001), and control (p = 0.002). Factors predicting reduced responses included older age, Child-Turcotte-Pugh B/C, and elevated IL-6 in cirrhosis; non-mRNA vaccine in AILD; and coronary artery disease, use of mycophenolate and dysregulated B-call activating factor, and lymphotoxin-α levels in LT. Incident infection occurred in 6.6%, 10.6%, 7.4%, and 15.6% of cirrhosis, AILD, post-LT, and control, respectively. The only independent factor predicting infection in cirrhosis was low albumin level. CONCLUSIONS: LT patients present the lowest response to the SARS-CoV-2 vaccine. In cirrhosis, the reduced response is associated with older age, stage of liver disease and systemic inflammation, and breakthrough infection with low albumin level.

ABSTRACT

Neurofilament light chain protein (NfL) levels reflect neuronal damage in several neurological diseases and have been proposed as a possible biomarker. Plasma extracellular vesicles (EVs) could play an important role as mediators of the inflammatory changes associated with inducing minimal hepatic encephalopathy (MHE) in cirrhotic patients. This study investigated the association of NfL levels in plasma and EVs with the presence of MHE in cirrhotic patients, and with responses to rifaximin treatment. The NfL levels in plasma and EVs were assessed in 71 patients with liver cirrhosis (40 with MHE and 31 without MHE) and 26 controls. A total of 31 patients with MHE received rifaximin treatment. We examined changes in NfL levels in plasma and EVs before and after 6 months of rifaximin treatment. The NfL measures were correlated with cognitive alterations and plasma inflammatory cytokines. MHE patients showed increased plasma levels of NfL, which were reverted after rifaximin treatment in patients who responded to treatment. The NfL content in EVs also showed a reversal pattern in MHE patients treated with rifaximin. In multivariable analyses, NfL levels were independently associated with the presence of MHE. We also showed that patients with high levels of both ammonia and fractalkine had significantly higher NfL levels than patients with low levels of least one of these parameters. Rifaximin treatment in MHE patients showed promising results in improving axonal damage, suggesting that rifaximin may have therapeutic benefits against disease progression in MHE.

ABSTRACT

Acute-on-chronic liver failure (ACLF) is defined by acute decompensation, organ failure and a high risk of short-term mortality. This condition is characterized by an overwhelming systemic inflammatory response. Despite treating the precipitating event, intensive monitoring and organ support, clinical deterioration can occur with very poor outcomes. During the last decades, several extracorporeal liver support systems have been developed to try to reduce ongoing liver injury and provide an improved environment for the liver to regenerate or as a bridging therapy until liver transplantation. Several clinical trials have been performed to evaluate the clinical efficacy of extracorporeal liver support systems, but no clear impact on survival has been proven. DIALIVE is a novel extracorporeal liver support device that has been built to specifically address the pathophysiological derangements responsible for the development of ACLF by replacing dysfunctional albumin and removing pathogen and damage-associated molecular patterns (PAMPs and DAMPs). In phase II clinical trial, DIALIVE appears to be safe, and it seems to be associated with a faster time to the resolution of ACLF compared with standard medical treatment. Even in patients with severe ACLF, liver transplantation saves lives and there is clear evidence of transplant benefit. Careful selection of patients is required to attain good results from liver transplantation, but many questions remain unanswered. In this review, we describe the current perspectives on the use of extracorporeal liver support and liver transplantation for ACLF patients.

ABSTRACT

The interest in vaccination efficacy and toxicity has surged following the Covid-19 pandemic. Immune responses to several vaccines have been shown to be suboptimal in patients with chronic liver disease (CLD) or post-liver transplant (LT), as a consequence of cirrhosis-associated immune dysfunction (CAID) or post-LT immunosuppression respectively. Accordingly, vaccine-preventable infections may be more common or severe than in the general population. The Covid-19 pandemic has greatly accelerated research and development into vaccination technology and platforms, which will have spillover benefits for liver patients. The aims of this review are: (i) to discuss the impact of vaccine-preventable infections on CLD and post-LT patients, (ii) to appraise current evidence supporting vaccination strategies, and (iii) to provide some insight into recent developments relevant for liver patients.

ABSTRACT

Patients with nonalcoholic fatty liver disease (NAFLD) may show mild cognitive impairment (MCI). The mechanisms involved remain unclear. The plasma concentrations of several cytokines and chemokines were measured in 71 NAFLD patients (20 with and 51 without MCI) and 61 controls. Characterization and activation of leukocyte populations and CD4+ sub-populations were carried out and analyzed by flow cytometry. We analyzed the cytokines released from CD4+ cell cultures and the mRNA expression of transcription factors and receptors in peripheral blood mononuclear cells. The appearance of MCI in NAFLD patients was associated with increased activation of CD4+ T lymphocytes, mainly of the Th17 subtype, increased plasma levels of pro-inflammatory and anti-inflammatory cytokines such as IL-17A, IL-23, IL-21, IL-22, IL-6, INF-γ, and IL-13, and higher expression of the CCR2 receptor. Constitutive expression of IL-17 was found in cultures of CD4+ cells from MCI patients, reflecting Th17 activation. High IL-13 plasma levels were predictive of MCI and could reflect a compensatory anti-inflammatory response to the increased expression of pro-inflammatory cytokines. This study identified some specific alterations of the immune system associated with the appearance of neurological alterations in MCI patients with NAFLD that could be the basis to improve and restore cognitive functions and quality of life in these patients.

ABSTRACT

BACKGROUND & AIMS: Neuropsychological and psychophysical tests are recommended to assess the risk of overt hepatic encephalopathy (OHE), but their accuracy is limited. Hyperammonaemia is central in the pathogenesis of OHE, but its predictive utility is unknown. In this study, we aimed to determine the role of neuropsychological or psychophysical tests and ammonia, and to develop a model (AMMON-OHE) to stratify the risk of subsequent OHE development in outpatients with cirrhosis. METHODS: This observational, prospective study included 426 outpatients without previous OHE from three liver units followed for a median of 2.5 years. Psychometric hepatic encephalopathy score (PHES) <-4 or critical flicker frequency (CFF) <39 was considered abnormal. Ammonia was normalized to upper limit of normal (AMM-ULN) at the respective reference laboratory. Multivariable frailty competing risk and random survival forest analyses were performed to predict future OHE and to develop the AMMON-OHE model. External validation was carried out using 267 and 381 patients from two independent units. RESULTS: Significant differences were found in time-to-OHE (log-rank p <0.001) according to PHES or CFF and ammonia, with the highest risk in patients with abnormal PHES plus high AMM-ULN (hazard ratio 4.4; 95% CI 2.4-8.1; p <0.001 compared with normal PHES and AMM-ULN). On multivariable analysis, AMM-ULN but not PHES or CFF was an independent predictor of the development of OHE (hazard ratio 1.4; 95% CI 1.1-1.9; p = 0.015). The AMMON-OHE model (sex, diabetes, albumin, creatinine and AMM-ULN) showed a C-index of 0.844 and 0.728 for the prediction of a first episode of OHE in two external validation cohorts. CONCLUSIONS: In this study, we developed and validated the AMMON-OHE model, comprising readily available clinical and biochemical variables that can be used to identify outpatients at the highest risk of developing a first episode of OHE. IMPACT AND IMPLICATIONS: In this study, we aimed to develop a model to predict which patients with cirrhosis are at risk of developing overt hepatic encephalopathy (OHE). Using data from three units and including 426 outpatients with cirrhosis, we developed the AMMON-OHE model - comprising sex, diabetes, albumin, creatinine and ammonia levels - which demonstrated good predictive ability. The AMMON-OHE model performs better than PHES and CFF to predict the first episode of OHE in outpatients with cirrhosis. This model was validated in 267 and 381 patients from two independent liver units. The AMMON-OHE model is available online for clinical use.

ABSTRACT

BACKGROUND & AIMS: Acute-on-chronic liver failure (ACLF) is characterized by severe systemic inflammation, multi-organ failure and high mortality rates. Its treatment is an urgent unmet need. DIALIVE is a novel liver dialysis device that aims to exchange dysfunctional albumin and remove damage- and pathogen-associated molecular patterns. This first-in-man randomized-controlled trial was performed with the primary aim of assessing the safety of DIALIVE in patients with ACLF, with secondary aims of evaluating its clinical effects, device performance and effect on pathophysiologically relevant biomarkers. METHODS: Thirty-two patients with alcohol-related ACLF were included. Patients were treated with DIALIVE for up to 5 days and end points were assessed at Day 10. Safety was assessed in all patients (n = 32). The secondary aims were assessed in a pre-specified subgroup that had at least three treatment sessions with DIALIVE (n = 30). RESULTS: There were no significant differences in 28-day mortality or occurrence of serious adverse events between the groups. Significant reduction in the severity of endotoxemia and improvement in albumin function was observed in the DIALIVE group, which translated into a significant reduction in the CLIF-C (Chronic Liver Failure consortium) organ failure (p = 0.018) and CLIF-C ACLF scores (p = 0.042) at Day 10. Time to resolution of ACLF was significantly faster in DIALIVE group (p = 0.036). Biomarkers of systemic inflammation such as IL-8 (p = 0.006), cell death [cytokeratin-18: M30 (p = 0.005) and M65 (p = 0.029)], endothelial function [asymmetric dimethylarginine (p = 0.002)] and, ligands for Toll-like receptor 4 (p = 0.030) and inflammasome (p = 0.002) improved significantly in the DIALIVE group. CONCLUSIONS: These data indicate that DIALIVE appears to be safe and impacts positively on prognostic scores and pathophysiologically relevant biomarkers in patients with ACLF. Larger, adequately powered studies are warranted to further confirm its safety and efficacy. IMPACT AND IMPLICATIONS: This is the first-in-man clinical trial which tested DIALIVE, a novel liver dialysis device for the treatment of cirrhosis and acute-on-chronic liver failure, a condition associated with severe inflammation, organ failures and a high risk of death. The study met the primary endpoint, confirming the safety of the DIALIVE system. Additionally, DIALIVE reduced inflammation and improved clinical parameters. However, it did not reduce mortality in this small study and further larger clinical trials are required to re-confirm its safety and to evaluate efficacy. CLINICAL TRIAL NUMBER: NCT03065699.
