Although hepatic ischemia/reperfusion injury (hIRI) has been shown to cause myocardial injury in rat and porcine models, the clinical association between hIRI and early myocardial dysfunction in humans has not yet been established. We sought to define this relationship through cardiac evaluation via transthoracic echocardiography (TTE) on postoperative day (POD) 1 in adult liver transplant recipients. MATERIAL AND METHODS TTE was performed on POD1 in all liver transplant patients transplanted between January 2020 and April 2021. Hepatic IRI was stratified by serum AST levels on POD1 (none: <200; mild: 200-2000; moderate: 2000-5000; severe: >5000). All patients had pre-transplant TTE as part of the transplant evaluation. RESULTS A total of 173 patients underwent liver transplant (LT) between 2020 and 2021 and had a TTE on POD 1 (median time to echo: 1 day). hIRI was present in 142 (82%) patients (69% mild, 8.6% moderate, 4% severe). Paired analysis between pre-LT and post-LT left ventricular ejection fraction (LVEF) of the entire study population demonstrated no significant decrease following LT (mean difference: -1.376%, P=0.08). There were no significant differences in post-LT LVEF when patients were stratified by severity of hIRI. Three patients (1.7%) had significant post-transplant impairment of LVEF (<35%). None of these patients had significant hIRI. CONCLUSIONS hIRI after liver transplantation is not associated with immediate reduction in LVEF.

MATERIAL AND METHODS In this multicenter, non-interventional study, LDLTRs with primary HCC, who were previously randomized to either everolimus plus reduced tacrolimus (EVR+rTAC) or standard tacrolimus (sTAC), and who completed the 2-year core H2307 study, were followed up.

Bile acids (BAs) play an important role in regulating inflammatory process, which is the major contributor to the development of CAD. The aim of this study was to evaluate the association between BAs metabolic dysregulation and CAD in KTRs. MATERIAL AND METHODS Fifteen serum BA species were determined in 43 healthy controls (HCs) and 131 KTRs by UPLC-MS/MS. KTRs were grouped into stable renal function (STA) and CAD1 and CAD2 groups based on eGFR levels. Circulating CYP7A1, CYP7B1, CYP27A1, and SLCO2B1 mRNA levels were determined by RT-PCR. RESULTS Total BA concentrations were comparable among the 4 groups. However, KTRs showed significantly different BAs profiling compared to HCs. KTRs with severe CAD (CAD2) had significantly lower unconjugated BAs and secondary BAs (SBAs) compared to the other 3 groups. KTRs had significantly lower SBAs/primary BAs (PBAs) ratios than HCs, which were comparable among the 3 KTR groups. Conjugated/unconjugated BAs ratios increased significantly with the deterioration of allograft function, which was further confirmed by correlation analysis. Differential correlation network analysis revealed that perturbations in intraclass and interclass BA coregulation existed during CAD progression. Moreover, relative gene expressions of CYP7B1 and CYP27A1 were positively correlated with eGFR.

MATERIAL AND METHODS The study included a representative Iasi population. Data were collected by means of a questionnaire focused on revealing attitudes toward organ donation, importance of consent, willingness to donate a family member's organs, and role of medical staff in the donation decision. A perception score was calculated as a methodological approach to validate attitudes toward organ donation. RESULTS Of all respondents, 55% agreed to donate their organs if declared brain-dead, while 20% opposed this idea; 72.7% considered consent necessary; 70% believed that consent must belong to the family when it comes to brain-dead organ donors; and 44.5% supported the idea of financial compensation. Higher monthly income was correlated with a positive attitude toward organ donation. CONCLUSIONS Even though the study population had a positive attitude toward organ donation, the willingness to donate was lower than in other European countries and did not translate into actual donations.

Outcomes of transplantation are dependent upon graft survival and can also be affected by superimposed cardiovascular morbidities. The present retrospective study was performed to assess the prevalence of cardiovascular risk factors before and after LTx. MATERIAL AND METHODS A retrospective review of 130 patients undergoing liver transplantation between October 2005 and April 2014 was completed. The mean age of the patients was 49.3±11.9 years. The prevalence of cardiovascular risk factors was assessed before and 2 years after transplantation. The prevalence of cardiovascular risk factors was assessed using a comparison based upon the etiologies of liver disease resulting in transplantation including alcohol, viral, and autoimmune processes using a chi-square analysis. RESULTS The prevalence of diabetes mellitus before and 2 years after liver transplantation (LTx) were 18% and 48% (P<0.001). Hypertension was documented in 24% of patients at baseline and 70% after 2 years of follow-up (P<0.001). The prevalence rates of diabetes mellitus before and 2 years after LTx were 18% and 48% (P<0.001). The prevalence of hypertriglyceridemia before and after LTx was 15% and 38%, respectively (P<0.001). Hypercholesterolemia was noted in 16% and 46%, respectively (P<0.001). Thirteen percent of patients before LTx and 18% after were obese (body mass index higher than 30 kg/m²). The annual incidence of diabetes mellitus, hypertension, hypertriglyceridemia, hypercholesterolemia, and obesity during the first 2 years after LTx was 15%, 23.5%, 15%, 18.5%, and 6%, respectively. Twenty-four percent of patients before and 10% after LTx admitted to tobacco use (P<0.001). The prevalence of diabetes (38% vs 67%, P=0.02), hypertriglyceridemia (19% vs 63%, P<0.001), hypercholesterolemia (28% vs 67%, P=0.002), and obesity (9% vs 33%, P=0.02) was lower in patients with an autoimmune cause of liver cirrhosis in comparison to patients with alcoholic disease. CONCLUSIONS The prevalence of hypertension and glucose and lipid metabolism abnormalities may increase in patients after liver transplantation. The prevalence of cardiovascular risk factors in patients after LTx may be related to the cause of liver injury before LTx.</p>","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2022-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/66/df/anntransplant-27-e935656.PMC9587686.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40320606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
