Background: The value of temporary intraoperative porto-caval shunts (TPCS) in cava-sparing liver transplantation is discussed controversially. Aim of this meta-analysis was to analyze the impact of temporary intraoperative porto-caval shunts on liver injury, primary non-function, time of surgery, transfusion of blood products and length of hospital stay in cava-sparing liver transplantation. Methods: A systematic search of MEDLINE/PubMed, EMBASE and PsycINFO retrieved a total of 909 articles, of which six articles were included. The combined effect size and 95 % confidence interval were calculated for each outcome by applying the inverse variance weighting method. Tests for heterogeneity (I2) were also utilized. Results: Usage of a TPCS was associated with significantly decreased AST values, significantly fewer transfusions of packed red blood cells and improved postoperative renal function. There were no statistically significant differences in primary graft non-function, length of hospital stay or duration of surgery. Conclusion: This meta-analysis found that temporary intraoperative porto-caval shunts in cava-sparing liver transplantation reduce blood loss as well as hepatic injury and enhance postoperative renal function without prolonging operative time. Randomized controlled trials investigating the use of temporary intraoperative porto-caval shunts are needed to confirm these findings. © 2016 Société Internationale de Chirurgie

Background. Subcutaneous administration of hepatitis B immunoglobulin (HBIg) is effective in preventing hepatitis B virus (HBV) recurrence after liver transplantation, but early conversion to subcutaneous administration is undocumented. Methods. In a prospective study, patients transplanted for terminal liver disease due to HBV infection who were HBV DNA-negative at transplant were switched by week 3 posttransplantation from intravenous to subcutaneous HBIg (500 or 1000 IU weekly or fortnightly, adjusted according to serumanti-HBs trough level) if they were HBsAg- and HBV-DNA negative at time of switch. All patients concomitantly received nucleos(t)ide analogue antiviral therapy. Primary endpoint was failure rate by month 6, defined as serum anti- HBs of 100 IU/L or less or HBV reinfection despite serum anti-HBs greater than 100 IU/L. Results. Of 49 patients treated, 47 (95.9%) continued treatment until month 6. All patients achieved administration by a caregiver or self-injection by week 14. No treatment failures occurred. Mean anti-HBs declined progressively to month 6, plateauing at a protective titer of approximately 290 IU/L. All patients tested for HBV DNA remained negative (45/45). Only 1 adverse event (mild injection site hematoma) was assessed as treatment-related. Conclusions. Introduction of subcutaneous HBIg administration by week 3 posttransplantation, combined with HBV virostatic prophylaxis, is effective and convenient for preventing HBV recurrence. © 2016 Wolters Kluwer Health, Inc.

Donor-recipient match is a matter of debate in liver transplantation. D-MELD (donor age x recipient biochemical model for end-stage liver disease [MELD]) and other factors were analyzed on a national Italian database recording 5946 liver transplants. Primary endpoint was to determine factors predictive of 3-year patient survival. D-MELD cutoff predictive of 5-year patient survival <50% (5 yrs PS<50%) was investigated. A prognosis calculator was implemented (www.D-MELD.com). Differences among D-MELD deciles allowed their regrouping into three D-MELD classes (A < 338, B 338-1628, C >1628). At 3 years, the odds ratio (OR) for death was 2.03 (95% confidence interval [CI], 1.44-2.85) in D-MELD class C versus B. The OR was 0.40 (95% CI, 0.24-0.66) in class A versus class B. Other predictors were hepatitis C virus (HCV; OR = 1.42; 95% CI, 1.11-1.81), hepatitis B virus (HBV; OR = 0.69; 95% CI, 0.51-0.93), retransplant (OR = 1.82; 95% CI, 1.16-2.87) and low-volume center (OR = 1.48; 95% CI, 1.11-1.99). Cox regressions up to 90 months confirmed results. The hazard ratio was 1.97 (95% CI, 1.59-2.43) for D-MELD class C versus class B and 0.42 (95% CI, 0.29-0.60) for D-MELD class A versus class B. Recipient age, HCV, HBV and retransplant were also significant. The 5 yrs PS<50% cutoff was identified only in HCV patients (D-MELD ≥ 1750). The innovative approach offered by D-MELD and covariates is helpful in predicting outcome after liver transplantation, especially in HCV recipients. © Copyright 2011 The American Society of Transplantation and the American Society of Transplant Surgeons.

Purpose: Liver injury triggered by intestinal ischemia-reperfusion (IIR) usually presage multiorgan dysfunction and death in patients. Recent studies suggest mesenchymal stem cells (MSCs) possess a protective potential against organ damage. Since relative evidence is insufficient and the mechanism is not well understood, we investigated the effect of hepatocyte growth factor c-Met signaling (HGF/c-Met) on recruitment of MSCs and subsequent protection against liver injury triggered by IIR in a rat model. Methods: IIR models were built as rats were subjected to 75 min of superior mesenteric artery occlusion and subsequent 4 h reperfusion. Either of pure MSCs and MSCs pretreated with HGF or SU11274 (c-Met inhibitor) were injected into rat models. Biochemical and pathologic alterations of liver in IIR model were measured to evaluate the therapeutic effect of MSCs and drug treatment. Concurrently, the effect of HGF and SU11274 on c-Met and phosphorylated Met expression in MSCs and MSCs migration were assessed in in vitro experiment. Results: IIR-induced liver injury was manifested by significant increase in serum ALT, AST and HGF levels as well as pathological change. MSCs with highly c-Met expression ameliorated the increase of serum transaminase levels and hepatic histopathological change, while SU11274 weaken these effects. HGF upregulated c-Met and phosphorylated Met expression in MSCs and enhanced its liver protection effect. Transwell assays demonstrated HGF promoted MSCs migration, which was blocked by SU11274. Conclusions: HGF/c-Met signaling pathway plays an essential role in the homing of MSCs towards injured liver triggered by intestinal ischemia-reperfusion, and then mediates MSC-induced liver repair. © Ivyspring International Publisher.

Hepatitis C virus (HCV) reinfection following liver transplant (LT) is associated with reduced graft and patients survival. Before transplant, Sofosbuvir/Ribavirin (SOF/R) treatment prevents recurrent HCV in 96% of those patients achieving viral suppression for at least 4 weeks before transplant. We evaluated whether a bridging SOF-regimen from pre to post-transplant is safe and effective to prevent HCV recurrence in those patients with less than 4 week HCV-RNA undetectability at the time of transplant.From July 2014 SOF/R was given in 233 waitlisted HCV cirrhotics with/without hepatocellular carcinoma (HCC) within an Italian Compassionate Program. One-hundred were transplanted and 31 patients (31%) treated by SOF/R bridging therapy were studied RESULTS: LT indication in bridge subgroup was HCC in 22 and decompensated cirrhosis in 9. HCV-genotype was 1/4 in 18 patients. SOF 400 mg/day and R (median dosage 800 mg/day) were given for a median of 35 days before LT. At transplant time, 19 patients were still HCV-RNA positive (median HCV-RNA 58 IU/ml). One recipient had a virological breakthrough at week 4 post-transplant; one died, on treatment, 1-month post-transplant for sepsis and 29/31 achieved a 12-week sustained virological response (94%). Acute cellular rejection occurred in 4 recipients. On September 2016, 30 recipients (97%) are alive with a median follow-up of 18 months (range 13-25).In patients with suboptimal virological response at LT a bridging SOF/R regimen helps avoiding post-transplant graft reinfection.
