Cytomegalovirus(CMV)infection is one of the primary causes of morbidity and mortality following liver transplantation(LT).Based on current worldwide guidelines,the most effective strategies for avoiding post-transplant CMV infection are antiviral prophylaxis and pre-emptive treatment.CMV-IgG serology is the established technique for pretransplant screening of both donors and recipients.The clinical presentation of CMV infection and disease exhibits variability,prompting clinicians to consistently consider this possibility,partic-ularly within the first year post-transplantation or subsequent to heightened immunosuppression.At annual symposia to discuss CMV prevention and how treatment outcomes can be improved,evidence on the incorporation of immune functional tests into clinical practice is presented,and the results of studies with new antiviral treatments are evaluated.Although there are ongoing studies on the use of letermovir and maribavir in solid organ transplantation,a consensus reflected in the guidelines has not been formed.Determining the most appro-priate strategy at the individual level appears to be the key to enhancing out-comes.Although prevention strategies reduce the risk of CMV disease,the disease can still occur in up to 50%of high-risk patients.A balance between the risk of infection and disease development and the use of immunosuppressants must be considered when talking about the proper management of CMV in solid organ transplant recipients.The objective of this study was to establish a compre-hensive framework for the management of CMV in patients who have had LT. 展开更多

BACKGROUND With an ongoing demand for transplantable organs,optimization of donor management protocols,specifically in trauma populations,is important for obta-ining a high yield of viable organs per patient.Endocrine management of brain-dead potential organ donors(BPODs)is controversial,leading to heterogeneous clinical management approaches.Previous studies have shown that when levo-thyroxine was combined with other treatments,including steroids,vasopressin,and insulin,BPODs had better organ recovery and survival outcomes were increased for transplant recipients.AIM To determine if levothyroxine use in combination with steroids in BPODs increased the number of organs donated in trauma patients.METHODS A retrospective review of adult BPODs from a single level 1 trauma center over ten years was performed.Exclusion criteria included patients who were not solid organ donors,patients who were not declared brain dead(donation after circulatory death),and patients who did not receive steroids in their hospital course.Levothyroxine and steroid administration,the number of organs donated,the types of organs donated,and demographic information were recorded.Univariate analyses were performed with P<0.05 considered to be statistically significant.RESULTS A total of 88 patients met inclusion criteria,69(78%)of whom received levothyroxine and steroids(ST/LT group)vs 19(22%)receiving steroids without levothyroxine(ST group).No differences were observed between the groups for gender,race,pertinent injury factors,age,or other hormone therapies used(P>0.05).In the ST/LT group,68.1%(n=47)donated a high yield(3-5)of organ types per donor compared to 42.1%(n=8)in the ST group(P=0.038).There was no difference in the total number of organ types donated between the groups(P=0.068).CONCLUSION This study suggests that combining levothyroxine and steroid administration increases high-yield organ donation per donor in BPODs in the trauma patient population.Limitations to this study include the retrospective design and the relatively small number of organ donors who met inclusion criteria.This study is unique in that it mitigates steroid administration as a confounding variable and focuses specifically on the adjunctive use of levothyroxine. 展开更多

BACKGROUND The outcomes of liver transplantation(LT)from different grafts have been studied individually and in combination,but the reports were conflicting with some researchers finding no difference in both short-term and long-term outcomes between the deceased donor split LT(DD-SLT)and living donor LT(LDLT).AIM To compare the outcomes of DD-SLT and LDLT we performed this systematic review and meta-analysis.METHODS This systematic review was performed in compliance with the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines.The following databases were searched for articles comparing outcomes of DD-SLT and LDLT:PubMed;Google Scholar;Embase;Cochrane Central Register of Controlled Trials;the Cochrane Database of Systematic Reviews;and Reference Citation Analysis(https://www.referencecitationanalysis.com/).The search terms used were:“liver transplantation;”“liver transplant;”“split liver transplant;”“living donor liver transplant;”“partial liver transplant;”“partial liver graft;”“ex vivo splitting;”and“in vivo splitting.”RESULTS Ten studies were included for the data synthesis and meta-analysis.There were a total of 4836 patients.The overall survival rate at 1 year,3 years and 5 years was superior in patients that received LDLT compared to DD-SLT.At 1 year,the hazard ratios was 1.44(95%confidence interval:1.16-1.78;P=0.001).The graft survival rate at 3 years and 5 years was superior in the LDLT group(3 year hazard ratio:1.28;95%confidence interval:1.01-1.63;P=0.04).CONCLUSION This meta-analysis showed that LDLT has better graft survival and overall survival when compared to DD-SLT. 展开更多

Background: The allo-immune response following organ transplantation constitutes one of the main determinants concerning both short- and long- term outcomes in renal graft recipients. Chemokines and their receptors play a diversified and important role, either homeostatic or inflammatory and direct different immune-competent cell types to the allograft. While deeply studied in the last two decades, controversy persists as a result of chemokines’ pleiotropic actions. We report our analysis of CCR1, CCR3, CCR7, CCL5 and CX3CL1 expression or synthesis by graft-infiltrating cells in human kidney transplants (KTx). At the same time, we tested their robustness in diagnosing acute rejection. Methods: Fine-needle aspiration biopsies (Fnab) were performed either on days 7 or 14 post-transplantation among stable KTx and on the day of acute rejection (AR) diagnosis. Fnab cytopreparations were studied by the enzymatic avidin-biotin complex staining for CCR1, CCR3, CCR7 and CX3CL1. From another subgroup of cases, Fnab samples were cultured for 48 hours and the supernatants were analysed for CCL5 by ELISA. Results: The group of AR cases showed a significantly up-regulated expression of CCR1, CCR3, CCR7 and CX3CL1 and a significantly higher synthesis of CCL5. The positive predictive values were respectively 92%, 97%, 85%, 76% and 78% and negative predictive values were by the same order, 100%, 73%, 100%, 98% and 83%. Conclusions: Our study permits us to advance that CCR1 and CCR3 play a significant and non-redundant role in acute rejection, and it is the first report of CCR3 association with rejection, probably related to CCL5. The presence inside the graft of significant up-regulation for CCR7 surmises that part of antigen presentation may be performed there without being restricted to secondary lymphoid sites. Our results with CX3CL1 confirm other reports. 展开更多

Drug-induced liver injury(DILI)is a major problem in the United States,commonly leading to hospital admission.Diagnosing DILI is difficult as it is a diagnosis of exclusion requiring a temporal relationship between drug exposure and liver injury and a thorough work up for other causes.In addition,DILI has a very variable clinical and histologic presentation that can mimic many different etiologies of liver disease.Objective scoring systems can assess the probability that a drug caused the liver injury but liver biopsy findings are not part of the criteria used in these systems.This review will address some of the recent updates to the scoring systems and the role of liver biopsy in the diagnosis of DILI. 展开更多

Metabolic dysfunction-associated steatotic liver disease(MASLD)has become the most common chronic liver disease worldwide,paralleling the rising pandemic of obesity and type 2 diabetes.Due to the growing global health burden and com-plex pathogenesis of MASLD,a multifaceted and innovative therapeutic approach is needed.Incretin receptor agonists,which were initially developed for diabetes management,have emerged as promising candidates for MASLD treatment.This review describes the pathophysiological mechanisms and action sites of three major classes of incretin/glucagon receptor agonists:glucagon-like peptide-1 receptor agonists,glucose-dependent insulinotropic polypeptide receptor agonists,and glucagon receptor agonists.Incretins and glucagon directly or indirectly impact various organs,including the liver,brain,pancreas,gastro-intestinal tract,and adipose tissue.Thus,these agents significantly improve glycemic control and weight management and mitigate MASLD pathogenesis.Importantly,this study provides a summary of clinical trials analyzing the effect-iveness and safety of incretin receptor agonists in MASLD management and provides an in-depth analysis highlighting their beneficial effects on improving liver function,hepatic steatosis,and intrahepatic inflammation.There are emerging challenges associated with the use of these medications in the real world,particularly adverse events,drug-drug interactions,and barriers to access,which are discussed in detail.Additionally,this review highlights the evolving role of incretin receptor agonists in MASLD management and suggests future research directions. 展开更多

Objective:To explore the effect of black radish(Raphanus sativus L.var niger)root extract on liver enzymes,oxidative stress,and histopathological alterations in mice with sodium valproate-induced hepatotoxicity.Methods:Thirty-two mice were divided into four groups:the control group received drinking water by gavage,the second group was administered with 100 mg/kg of sodium valproate,the third group received 300 mg/kg of black radish root extract,and the fourth group was given both sodium valproate(100 mg/kg)and black radish root extract(300 mg/kg).After 28 days,the mice were euthanized,and serum levels of aspartate aminotransferase(AST),alanine aminotransferase(ALT),and alkaline phosphatase(ALP),along with liver malondialdehyde(MDA),reactive oxygen species(ROS),mitochondrial parameters,tumor necrosis factor-alpha(TNF-α)gene expression,and histopathological changes were assessed.Results:Sodium valproate caused hepatic damage in mice,characterized by elevated serum levels of liver enzymes,increased MDA and ROS levels and TNF-αgene expression,as well as histopathological alterations.The black radish root extract significantly alleviated sodium valproate-caused hepatic injury by decreasing the serum levels of ALT and AST,MDA,ROS,TNF-αgene expression,as well as mitochondrial impairment,but did not have a significant effect on sodium valproate-induced histopathological changes.Conclusions:The black radish root extract demonstrates protective effects against sodium valproate-induced liver injury,possibly through mitigating oxidative stress,mitochondrial impairment,and inflammatory mediator expression. 展开更多

BACKGROUND Sport-induced injuries particularly affect young,healthy,and active individuals.Running,a popular and accessible sport,can cause a wide range of injuries,including stress fractures.Stress fractures can occur during high-intensity training or competitions,especially among well-trained amateurs and professional athletes.Adequate diagnosis can be complicated by the typically young age,unremarkable medical history,and vital condition of the patient.Stress fractures present insidiously,and this is specifically the case with stress fractures of the femoral neck.Timely intervention is crucial to prevent progressive displacement,as this can damage the blood supply to the femoral head.CASE SUMMARY A 30-year-old male runner presented to our outpatient clinic with persistent pain 3 weeks after running a marathon.X-ray showed a complete lateral fracture of the left femoral neck,which was treated surgically with a dynamic hip screw.CONCLUSION It is essential for healthcare providers to be vigilant for the subtle symptoms of stress fractures to ensure timely treatment.Early recognition prevents com-plication and leads to a better prognosis. 展开更多

AIM: To assess the value of pre-transplant artificial liver support in reducing the pre-operative risk factors relating to early mortality after orthotopic liver transplantation (OLT). METHODS: Fifty adult patients with various stages and various etiologies undergoing OLT procedures were treated with molecular adsorbent recycling system (MARS) as preoperative liver support therapy. The study included two parts, the first one is to evaluate the medical effectiveness of single MARS treatment with some clinical and laboratory parameters, which were supposed to be the therapeutical pre-transplant risk factors, the second part is to study the patients undergoing OLT using the regression analysis on preoperative risk factors relating to early mortality (30 d) after OLT. RESULTS: In the 50 patients, the statistically significant improvement in the biochemical parameters was observed (pre-treatment and post-treatment). Eight patients avoided the scheduled Ltx due to significant relief of clinical condition or recovery of failing liver function, 8 patients died, 34 patients were successfully bridged to Ltx, the immediate outcome of this 34 patients within 30d observation was: 28 kept alive and 6 patients died. CONCLUSION: Pre-operative SOFA, level of creatinine, INR, TNF-α, IL-10 are the main preoperative risk factors that cause early death after operation, MARS treatment before transplantion can relieve these factors significantly. 展开更多

Liver resection(LR) and primary liver transplantation(LT) are two potentially curative treatment modalities for patients with hepatocellular carcinoma(HCC).If an underlying chronic liver disease exists,however,making a decision on which method should be selected is difficult.If a patient has no chronic liver disease,LR may be the preferable option with salvage transplantation(ST) in mind in case of recurrence.Presence of a moderate-to-severe liver failure accompanying HCC usually warrants primary LT.The treatment of patients with HCC and early-stage chronic liver disease remains controversial.The advantages of "LR-followed-by-STif-needed" strategy include less complicated index operation,no need for immunosuppression,use of donor livers for other patients in today's organ shortage setting and comparable survival rates.However,primary LT has its own advantages as it also treats underlying chronic liver disease with carcinogenic potential,removes undetected tumor nodules and potentially eliminates need for a ST.An article recently published by Fuks et al in Hepatology offers an approach by which selecting between LR-followed-by-ST and immediate LT might be easier.Here we discuss the results of the aforementioned report in the light of currently available knowledge. 展开更多

There are also shortages of human blood for transfusion. A potential solution to all of these problems is the transplantation of organs, cells, and corneas from a readily available animal species, such as the pig, and the transfusion of red blood cells from pigs into humans. However, to achieve these ends, major immunologic and other barriers have to be overcome. Considerable progress has been made in this respect by the genetic modification of pigs to protect their tissues from the primate immune response and to correct several molecular incompatibilities that exist between pig and primate. These have included knockout of genes responsible for the expression of major antigenic targets for primate natural anti-pig antibodies, insertion of human complement- and coagulation-regulatory transgenes, and knockdown of swine leukocyte antigens that stimulate the primate's adaptive immune response. As a result of these manipulations, the administration of novel immunosuppressive agents, and other innovations, pig hearts have now functioned in baboons for 6-8 months, pig islets have maintained normoglycemia in diabetic monkeys for 〉 1 year, and pig corneas have maintained transparency for several months. Clinical trials of pig islet trans- plantation are already in progress. Future developments will involve further genetic manipulations of the organ- source pig, with most of the genes that are likely to be beneficial already identified. 展开更多

Mesenchymal hamartomas of the liver(MHLs) in adults are rare and potentially premalignant lesions, which present as solid/cystic neoplasms. We report a rare case of orthotopic liver transplantation in a patient with a giant MHL. In 2013, a 34-year-old female sought medical advice after a 2-year history of progressive abdominal distention and respiratory distress. Physical examination revealed an extensive mass in the abdomen. Computed tomography(CT) of her abdomen revealed multiple liver cysts, with the diameter of largest cyst being 16 cm × 14 cm. The liver hilar structures were not clearly displayed. The adjacent organs were compressed and displaced. Initial laboratory tests, including biochemical investigations and coagulation profile, were unremarkable. Tumor markers, including levels of AFP, CEA and CA19-9, were within the normal ranges. The patient underwent orthotopic liver transplantation in November 2013, the liver being procured from a 40-year-old man after cardiac death following traumatic brain injury. Warm ischemic time was 7.5 min and cold ischemic time was 3 h. The recipient underwent classical orthotopic liver transplantation. The recipient operative procedure took 8.5 h, the anhepatic phase lasting for 1 h without the use of venovenous bypass. The immunosuppressive regimen includedintraoperative induction with basiliximab and high-dose methylprednisolone, and postoperative maintenance with tacrolimus, mycophenolate mofetil, and prednisone. The recipient's diseased liver weighed 21 kg(dry weight) and measured 41 cm × 32 cm × 31 cm. Histopathological examination confirmed the diagnosis of an MHL. The patient did not experience any acute rejection episode or other complication. All the laboratory tests returned to normal within one month after surgery. Three months after transplantation, the immunosuppressive therapy was reduced to tacrolimus monotherapy, and the T-tube was removed after cholangiography showed no abnormalities. Twelve months after transplantation, the patient remains well and is fulfilling all normal activities. Adult giant MHL is extremely rare. Symptoms, physical signs, laboratory results, and radiographic imaging are nonspecific and inconclusive. Surgical excision of the lesion is imperative to make a definite diagnosis and as a cure. Liver transplantation should be considered as an option in the treatment of a non-resectable MHL. 展开更多

Pre-recovery assessment of liver graft volume is essential for selecting suitable recipients. The purpose of this study was to determine the ability and feasibility of constructing a 3-D model to aid in surgical planning and to predict graft weight prior to an in situ division of the donor liver. METHODS: Over 11 months, 3-D volumetric reconstruction of 4 deceased donors was performed using Pathfinder Scout liver volumetric software. Demographic, laboratory, operative, perioperative and survival data for these patients along with donor demographic data were collected prospectively and analyzed retrospectively. RESULTS: The average predicted weight of the grafts from the adult donors obtained from an in situ split procedure were 1130 g (930-1458 g) for the extended right lobe donors and 312 g (222-396 g) for left lateral segment grafts. Actual adult graft weight was 92% of the predicted weight for both the extended right grafts and the left lateral segment grafts. The predicted and actual graft weights for the pediatric donors were 176 g and 210 g for the left lateral segment grafts and 308 g and 280 g for the extended right lobe grafts,respectively. All grafts were transplanted except for the right lobe from the pediatric donors due to the small graft weight.CONCLUSIONS: On-site volumetric assessment of donors provides useful information for the planning of an in situ split and for selection of recipients. This information may expand the donor pool to recipients previously felt to be unsuitable due to donor and/or recipient weight. 展开更多

AIM To perform a systematic review and meta-analysis on minimally vs conventional invasive techniques for harvesting grafts for living donor liver transplantation. METHODS PubMed, Web of Science, EMBASE, and the Cochrane Library were searched comprehensively for studies comparing MILDH with conventional living donor hepatectomy (CLDH). Intraoperative and postoperative outcomes (operative time, estimated blood loss, postoperative liver function, length of hospital stay, analgesia use, complications, and survival rate) were analyzed in donors and recipients. Articles were included if they: (1) compared the outcomes of MILDH and CLDH; and (2) reported at least some of the above outcomes. RESULTS Of 937 articles identified, 13, containing 1592 patients, met our inclusion criteria and were included in the meta-analysis. For donors, operative time [weighted mean difference (WMD) = 20.68, 95% CI: -6.25-47.60, p = 0.13] and blood loss (WMD = -32.61, 95% CI: -80.44-5.21, p = 0.18) were comparable in the two groups. In contrast, analgesia use (WMD = -7.79, 95% CI: -14.06-1.87, p = 0.01), postoperative complications [odds ratio (OR) = 0.62, 95% CI: 0.44-0.89, p = 0.009], and length of hospital stay (WMD): -1.25, 95% CI: -2.35-0.14, p = 0.03) significantly favored MILDH. No differences were observed in recipient outcomes, including postoperative complications (OR = 0.93, 95% CI: 0.66-1.31, p = 0.68) and survival rate (hr = 0.96, 95% CI: 0.27-3.47, p = 0.95). Funnel plot and statistical methods showed a low probability of publication bias. CONCLUSION MILDH is safe, effective, and feasible for living donor liver resection with fewer donor postoperative complications, reduced length of hospital stay and analgesia requirement than CLDH. 展开更多

BACKGROUND Depression,anxiety,and altered self-care ability are among the most important factors affecting the quality of life of liver transplant recipients.Depending on the severity of the underlying liver disease,signs and symptoms of anxiety and depression may become more pronounced.AIM To evaluate the factors affecting depression,anxiety and self-care abilities of liver transplant recipients.METHODS Recipients who are≥18 years and who underwent liver transplantation at Inonu University Liver Transplantation Institute were included in this descriptive and cross-sectional study.Sample size analysis showed that the minimum number of recipients should be 301(confidence level=95%,confidence interval=2.5,population=1382).Three hundred and twenty recipients were interviewed and 316 recipients that have answered the questionnaires accurately were analyzed.The dependent variables were the Beck Depression Scale,State-Trait Anxiety Scale(Form I and II),and Self-Care Agency Scale.The independent variables of the study were sociodemographic characteristics,biliary complications,hepatocellular carcinoma,recommending liver transplantation to other patients,and the interval of out-patient clinic visits.RESULTS Self-care ability scores were lower(P=0.002)and anxiety scores were higher(P=0.004)in recipients with biliary complications.On the other hand,in recipients with hepatocellular carcinoma,self-care scores were lower(P=0.006)while depression(P=0.003)and anxiety scores(P=0.009)were higher.Liver transplantation recipients with a monthly income<3000 Turkish liras had higher depression(P<0.001)and anxiety(P=0.003)scores.The recipients who stated that they would not recommend liver transplantation to others had lower self-care scores(P=0.002),higher depression(P<0.001),higher state anxiety(P=0.02),and trait anxiety(P<0.001)scores.CONCLUSION Presence of biliary complications and hepatocellular carcinoma,low income level,and an obligation for monthly visits to the outpatient clinic are factors that are found to affect self-care capability,depression,and anxiety. 展开更多

It is estimated that about 350 million people throughout the world are chronically infected with HBV. Some of these people will develop hepatic cirrhosis with decompensation and/or hepatocellular carcinoma. For such patients, liver transplantation may be the only hope for cure or real improvement in quality and quantity of life. Formerly, due to rapidity of recurrence of HBV infection after liver transplantation, usually rapidly progressive, liver transplantation was considered to be contraindicated. This changed dramatically following the demonstration that hepatitis B immune globulin (HBIG), could prevent recurrent HBV infection. HBIG has been the standard of care for the past two decades or so. Recently, with the advent of highly active inhibitors of the ribose nucleic acid polymerase of HBV (entecavir, tenofovir), there has been growing evidence that HBIG needs to be given for shorter lengths of time; indeed, it may no longer be necessary at all. In this review, we describe genetic variants of HBV and past, present, and future prophylaxis of HBV infection during and after liver transplantation. We have reviewed the extant medical literature on the subject of infection with the HBV, placing particular emphasis upon the prevention and treatment of recurrent HBV during and after liver transplantation. For the review, we searched PubMed for all papers on the subject of &#x0201c;hepatitis B virus AND liver transplantation&#x0201d;. We describe some of the more clinically relevant and important genetic variations in the HBV. We also describe current practices at our medical centers, provide a summary and analysis of comparative costs for alternative strategies for prevention of recurrent HBV, and pose important still unanswered questions that are in need of answers during the next decade or two. We conclude that it is now rational and cost-effective to decrease and, perhaps, cease altogether, the routine use of HBIG during and following liver transplantation for HBV infection. Here we propose an individualized prophylaxis regimen, based on an integrated approach and risk-assessment. 展开更多

Progressive familial intrahepatic cholestasis(PFIC) is a constellation of inherited disorders that result in the impairment of bile flow through the liver that predominantly affects children. The accumulation of bile results in progressive liver damage, and if left untreated leads to end stage liver disease and death. Patients often present with worsening jaundice and pruritis within the first few years of life. Many of these patients will progress to end stage liver disease and require liver transplantation. The role and timing of liver transplantation still remains debated especially in the management of PFIC1. In those patients who are appropriately selected, liver transplantation offers an excellent survival benefit. Appropriate timing and selection of patients for liver transplantation will be discussed, and the short and long term management of patients post liver transplantation will also be described. 展开更多
