Abstract
Acute liver failure (ALF) is a rare and serious condition characterized by major hepatocyte death and liver dysfunction. Owing to the limited therapeutic options, this disease generally has a poor prognosis and a high mortality rate. When ALF cannot be reversed by medications, liver transplantation is often needed. However, transplant rejection and the shortage of donor organs still remain major challenges. Most recently, stem cell therapy has emerged as a promising alternative for the treatment of liver diseases. However, the limited cell delivery routes and poor stability of live cell products have greatly hindered the feasibility and therapeutic efficacy of stem cell therapy. Inspired by the functions of mesenchymal stem cells (MSCs) primarily through the secretion of several factors, we developed an MSC-inspired biomimetic multifunctional nanoframework (MBN) that encapsulates the growth-promoting factors secreted by MSCs via combination with hydrophilic or hydrophobic drugs. The red blood cell (RBC) membrane was coated with the MBN to enhance its immunological tolerance and prolong its circulation time in blood. Importantly, the MBN can respond to the oxidative microenvironment, where it accumulates and degrades to release the payload. In this work, two biomimetic nanoparticles, namely, rhein-encapsulated MBN (RMBN) and N-acetylcysteine (NAC)-encapsulated MBN (NMBN), were designed and synthesized. In lipopolysaccharide (LPS)/d-galactosamine (D-GalN)-induced and acetaminophen (APAP)-induced ALF mouse models, RMBN and NMBN could effectively target liver lesions, relieve the acute symptoms of ALF, and promote liver cell regeneration by virtue of their strong antioxidative, anti-inflammatory, and regenerative activities. This study demonstrated the feasibility of the use of an MSC-inspired biomimetic nanoframework for treating ALF.

Correlation between serum pro-inflammatory cytokine levels and the prognosis of the patients with acute liver failure. J Gastroenterol Hepatol 2023; 38:1637-1646. [PMID: 37475200 DOI: 10.1111/jgh.16300] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Revised: 05/31/2023] [Accepted: 07/02/2023] [Indexed: 07/22/2023]
Abstract
BACKGROUND AND AIM The prognosis of acute liver failure (ALF) remains poor, and liver transplantation is an alternative treatment option. Assessing the prognosis of ALF is important in determining treatment strategies. Here, we investigated clinical factors including serum pro-inflammatory cytokine levels that are associated with the prognosis of ALF. METHODS Sixty-six patients who developed ALF were enrolled in this study. Serum concentrations of 12 pro-inflammatory cytokines were measured on admission. The prognosis and factors associated with survival and development of hepatic coma were analyzed. RESULTS Of 66 patients, 4 patients underwent liver transplantation, and 49 patients were rescued without liver transplantation, while the remaining 13 patients died. Serum concentrations of interleukin (IL)-1β, IL-4, IL-6, IL-8, IL-13, TNF, IFN -γ, IP-10, and G-CSF were significantly elevated in ALF patients. IL-4 and IL-8 levels were higher in patients who underwent liver transplantation or died than in rescued patients. Multivariable analysis identified age ≥ 55 years and IL-4 ≥ 1.2 pg/mL on admission as independent factors for mortality. Serum IL-8 levels were higher in patients with hepatic coma, and prothrombin-international normalized ratio ≥ 3.5 and IL-8 ≥ 77.2 pg/mL on admission were associated with development of hepatic coma after admission. CONCLUSION Serum levels of several pro-inflammatory cytokines were elevated in ALF patients. IL-4 and IL-8 were correlated with survival and development of hepatic coma after admission, respectively. Measurement of serum pro-inflammatory cytokines seems to be useful for the management of ALF.

Early-phase prothrombin time-international normalized ratio in acute liver injury indicates the timing of therapeutic intervention and predicts prognostic improvement. Hepatol Res 2023; 53:160-171. [PMID: 36301000 DOI: 10.1111/hepr.13848] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 10/14/2022] [Accepted: 10/20/2022] [Indexed: 02/07/2023]
Abstract
AIM We investigated whether an early-phase prothrombin time-international normalized ratio (PT-INR) is an interventional prognostic indicator for patients with acute liver injury, including acute liver failure. METHODS This was a multicenter retrospective observational study. We included 595 patients with alanine aminotransferase levels ≥300 U/L due to acute liver injury who were admitted to Kagoshima University Hospital or other collaborative investigation organizations between January 1, 2010, and December 31, 2015. Patients with alanine aminotransferase levels ≥300 U/L and no previous liver disease were defined as having an acute liver injury. Acute liver failure was defined by PT-INR ≥1.5 with or without hepatic encephalopathy in acute liver injury patients. Data were obtained retrospectively from case reports and analyzed. RESULTS The PT-INR on day 1 was the most accurate independent prognosis predictor in patients with acute liver injury and acute liver failure. On day 1, the transplant-free survival rates were significantly lower in patients with PT-INR ≥1.3. The transplant-free survival rates were also significantly higher in patients with acute liver injury and acute liver failure, in whom the PT-INR had recovered from ≥1.3 on day 1 to <1.3 by day 8. CONCLUSION Early-phase changes in the PT-INR can predict the prognosis of patients with acute liver injury and acute liver failure. Furthermore, PT-INR ≥1.3 could be an interventional marker, whereas PT-INR <1.3 after 1 week could reflect prognostic improvement.

Allograft liver failure awaiting liver transplantation in Japan. J Gastroenterol 2022; 57:495-504. [PMID: 35648201 DOI: 10.1007/s00535-022-01880-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Accepted: 05/14/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND Following liver transplantation (LT), allograft liver failure can be developed by various causes and requires re-LT. Hence, this study aimed to clarify the characteristics and prognostic factors of patients with allograft liver failure awaiting deceased donor LT (DDLT) in Japan. METHODS Of the 2686 DDLT candidates in Japan between 2007 and 2016, 192 adult patients listed for re-LT were retrospectively enrolled in this study. Factors associated with waitlist mortality were assessed using the Cox proportional hazards model. The transplant-free survival probabilities were evaluated using the Kaplan-Meier analysis and log-rank test. RESULTS The median period from the previous LT to listing for re-LT was 1548 days (range, 4-8449 days). Primary sclerosing cholangitis (PSC), which was a primary indication, showed a higher listing probability for re-LT as compared with other primary etiologies. Recurrent liver disease was a leading cause of allograft failure and was more frequently observed in the primary indication of hepatitis C virus (HCV) infection and PSC in contrast with other etiologies. Multivariate analysis identified the following independent risk factors associated with waitlist mortality: age, Child-Turcotte-Pugh (CTP) score, mode for end-stage liver disease (MELD) score, alanine aminotransferase (ALT), and causes of allograft failure. CONCLUSIONS Recurrent HCV and PSC were major causes of allograft liver failure in Japan. In addition to CTP and MELD scores, either serum ALT levels or causes of allograft failure should be considered as graft liver allocation measures.

Abstract
BACKGROUND The main causes of liver cirrhosis have changed over the past decade. In Japan, the number of deceased donors is increasing but is still insufficient relative to the number of patients awaiting a liver transplant. This study aimed to assess the outcomes of candidates for liver transplantation. METHODS This was a retrospective study of adult patients who visited our department for consultation regarding liver transplantation from January 2009 to December 2020. Of a total of 601 patients, 336 were followed-up. The following data were collected and analyzed: patient's characteristics, liver etiology, Child-Pugh and MELD scores, and the eventual outcome, that is, whether liver transplantation was performed. RESULTS Only 153 of 336 (45.5%) patients underwent liver transplantation, of which 42 (27.5%) received deceased donor liver transplantation, and 129 (38.4%) died without transplantation. The proportion of patients who underwent liver transplantation was low among patients with nonalcoholic steatohepatitis (NASH) (10.7%) (P<0.001). The rate of qualified living donors was the lowest for patients with NASH (28.6%) and that for the other etiologies ranged from 55.6% to 67.4% (P=0.050). CONCLUSION Patients with liver cirrhosis due to NASH may have a lesser chance of undergoing liver transplantation from both living and deceased donors.
