    Innovative Technique Avoiding Bleeding After Reperfusion in Living Donor Liver Transplant Using a Modified Right Lobe Graft
    (2022) PINHEIRO, Rafael S.; ANDRAUS, Wellington; FORTUNATO, Allana C.; FERNANDES, Michel Ribeiro; NACIF, Lucas Souto; MARTINO, Rodrigo Bronze De; DUCATTI, Liliana; WAISBERG, Daniel Reis; ARANTES, Rubens Macedo; ROCHA-SANTOS, Vinicius; GALVAO, Flavio Henrique Ferreira; CARNEIRO-D'ALBUQUERQUE, Luiz Augusto
    Background. Living donor liver transplant (LDLT) is a valuable therapeutic option for over-coming the deceased donor shortage. Modified right lobe graft (MRLG) keeps the middle hepatic vein (MHV) trunk with the remnant liver to improve donor safety. Hemostasis in the MHV tributary reconstruction can be tricky; surgical stitches and energy coagulation are ineffective. Fibrin glues are excellent vascular sealants but are poor in maintaining hemostasis in an active hemorrhage or preventing resection surface-related complications after liver resection. We propose applying fibrin sealant during back table graft preparation to seal the hepatic edge and MHV reconstruction to avoid bleeding after graft revascularization. Methods. Our retrospective cohort study included all adult patients undergoing LDLT between August 2017 and December 2021. During the back table procedure, we performed the reconstruction of the inferior right hepatic vein and/or MHV tributaries from segment 5 (V5) and segment 8 (V8) using a vein harvested from a nonrelated deceased donor. Before initiating the hepatic graft implantation, we applied fibrin sealant in the resected parenchyma, especially in the V5 and V8 anastomosis, to seal the hepatic edge and hepatic vein reconstruction. Results. No bleeding was identified in the hepatic edge, and blood product transfusion was unnecessary for any recipients after reperfusion. Conclusion. In LDLT using MRLG with MHV reconstruction, the fibrin sealant, when applied on the raw hepatic surface, and vascular reconstruction during back table graft preparation avoided bleeding after graft revascularization.

    Ten Years' Evaluation of Potential Pancreas Donors in Sao Paulo, Brazil
    (2014) PINHEIRO, R. S.; ROCHA-SANTOS, V.; PECORA, R. A.; MACEDO, R. A.; NACIF, L. S.; ANDRAUS, W.; DAVID, A. I.; PANTANALI, C. A.; BENITES, C. M.; D'ALBUQUERQUE, L. A. C.
    Background. Pancreas transplantation is a treatment for advanced type 1 diabetes and offers significant improvement in quality of life. Recent advances in surgical techniques and immunosuppression regimes lead to good outcomes. However, despite significant higher rates of multiorgan donors in Brazil, pancreas transplantation seems to have remained stable. This study aimed to investigate the acceptance rate of potential pancreas donors in the past 10 years in Sao Paulo State. Methods. We retrospectively evaluated potential pancreas donors characteristics and its acceptance rate in Sao Paulo State in the past 10 years. We divided this period into 2 eras: 1st era from January 2003 to January 2008; and 2nd era from January 2008 to January 2013. Data were obtained from Sao Paulo's government official website. Results. During the whole period, 5,005 deceased donors of all ages were available for pancreas transplantation. According to eras, we had 1,588 donors in the 1st and 3,417 in the 2nd era. In the 2nd era, donors >49 years old were significantly more common (P < .001). Blood test abnormalities, donor comorbidities, and high dosage of vasopressors also were significantly higher in the 2nd era. Rate of graft acceptance had a significant decrease in the 2nd era, from 46.4% to 25% (P < .05). Conclusions. Despite greater organ availability, pancreas transplantations performed in Sao Paulo State remained stable. Rate of graft acceptance is dramatically lower in more recent years.

    Evolution of Biomarkers of Atherogenic Risk in Liver Transplantation Recipients
    (2018) LINHARES, L. M. C.; OLIVEIRA, C. P.; ALVARES-DA-SILVA, M. R.; STEFANO, J. T.; BARBEIRO, H. V.; BARBEIRO, D. F.; TERRABUIO, D. R. B.; ABDALA, E.; SORIANO, F. G.; CARRILHO, F. J.; FARIAS, A. Q.; SIDDIQUI, M. S.; D'ALBUQUERQUE, L. A. C.
    Background. Cardiovascular disease is a major contributing factor to long-term mortality after liver transplantation (LT). Methods. This study evaluated the evolution of atherogenic risk in liver transplant recipients (LTRs). Thirty-six subjects were prospectively enrolled at 12 months and followed for 48 months after liver transplantation. Serum biomarkers of endothelial dysfunction (sICAM-1 and sVCAM-1), chronic inflammation (serum amyloid A), and oxidative stress (myeloperoxidase) were measured at 12 and 48 months after LT. Additionally, at 12 months all patients underwent a cardiac computed tomography (CT) scan and a coronary artery calcium score (CACS). Results. The prevalence of risk factors of metabolic syndrome (MS) increased over the course of the study. The patients' sVCAM-1 and sICAM-1 increased from 1.82 +/- 0.44 ng/mL to 9.10 +/- 5.82 ng/mL (P < .001) and 0.23 +/- 0.09 ng/mL to 2.7 +/- 3.3 ng/mL, respectively from month 12 to 48. Serum myeloperoxidase increased from 0.09 +/- 0.07 ng/mL to 3.46 +/- 3.92 ng/mL (P < .001) over the course of the study. Serum amyloid A also increased from 21.4 +/- 40.7 ng/mL at entry to 91.5 +/- 143.6 ng/mL at end of study (P < .001). Conclusion. No association between these biomarkers and MS was noted. The cardiac CT revealed mild and moderate disease in 19% and 25% of the cohort, respectively. No association between serum biomarkers and CACS was noted. Serum biomarkers of atherogenic risk increase rapidly in LTRs and precede coronary plaques.

    Effect of Hepatic Preconditioning with the Use of Methylene Blue on the Liver of Wistar Rats Submitted to lschemia and Reperfusion
    (2018) ALMEIDA, T. N. de; VICTORINO, J. P.; LIU, J. Bistafa; CAMPOS, D. Tofoli Queiroz; GRAF, C.; JORDANI, M. C.; D'ALBUQUERQUE, L. A. Carneiro; MENDES, K. D. S.; CASTRO-E-SILVE, O.
    Background. The liver may be injured in situations where it is submitted to ischemia, such as partial hepatectomy and liver transplantation. In all cases, ischemia is followed by reperfusion and, although it is essential for the reestablishment of tissue function, reperfusion may cause greater damage than ischemia, an injury characterized as ischemia-reperfusion (I/R) damage. The aim of this work was to analyze the effect of ischemic preconditioning with the use of methylene blue (MB; 15 mg/kg) 5 or 15 minutes before I/R (IRMB5' and IRMB15', respectively) on the hepatic injury occurring after I/R. Methods. Twenty-eight male Wistar rats were used, and liver samples submitted to partial ischemia (IR) or not (NI) were obtained from the same animal. The samples were divided into 7 groups. Data were analyzed statistically by means of the nonparametric Mann-Whitney test and Wilcoxon Matched test, with the level of significance set at 5% (P < .05). Results. The rate of oxygen consumption by state 3 mitochondria was inhibited in all ischemic groups compared with the sham group (SH vs IR: P = .0052; SH vs IRMB5': P = .0006; SH vs IRMB15': P = .0048), which did not occur in the nonischemic contralateral portion of the same liver (SH vs NI: P = .7652; SH vs NIMB5': P = .059; SH vs NIMB15': P = .3153). The inhibition of the rate of oxygen consumption by state 3 mitochondria was maintained in the presence of MB (IR vs IRMB5': P = .4563; IR vs IRMB15': P = .9021). The respiratory control ratio was reduced in all ischemic groups compared with the sham group, owing to the inhibition of oxygen consumption in state 3 (SH vs IR: P = .0151; SH vs IRMB5': P = .005; SH vs IRMB15': P = .0007). Conclusions. Methylene blue had no effect on the mitochondrial respiratory parameters studied, but was able to reduce lipid peroxidation, preventing the production of reactive oxygen species (SH vs IRMB15': P = .0210).

    (2023) BOIN, Ilka Fsf; RICCETTO, Eduardo; GENZINI, Tercio; SANTOS, Regina Gomes; MOREIRA, Lucio Figueira Pacheco; PINTO, Laura Cristina Machado; GARCIA, Jose Huygens Parente; STUCCHI, Raquel Sb; PERALES, Simone Reges; ZANAGA, Leticia; SILVA, Renato Fereira Da; SILVA, Rita Cm Fereira Da; HADDAD, Luciana; D'ALBUQUERQUE, Luiz Ac; DEALMEIDA, Marcio Dias; WATANABE, Andre; PEIXOTO, Gustavo S.; MELO, Claudio Moura Lacerda De; BEZERRA, Renata Ferreira; TEFILLI, Nertan Luiz; HALPERN, Marcia; GODOY, Maira Silva; NOGARA, Marcelo; MANCERO, Jorge Marcelo Padilla; NOUJAIM, Huda Maria; RANGEL, Erika Bevilaqua; ATAIDE, Elaine Cristina
    Background. Infections by SARS-CoV-2 in liver transplant recipients (LT) patients are of particular concern, notably due to perceived added risks related to immunosuppression and comorbidity burden. Current literature on this topic often relies on small, non-standardized, and geographically limited studies. This manuscript describes COVID-19 presentations and causes for elevated mortality in a large cohort of LT recipients. Methods. This study was designed as a multicentric historical cohort, including LT recipient patients with COVID-19 in 25 study centers, with the primary endpoint being COVID-related death. We also collected demographic, clinical, and laboratory data regarding presentation and disease progression. Results. Two hundred and thirty-four cases were included. The study population was predominantly male and White and had a median age of 60 years. The median time from transplantation was 2.6 years (IQR 1-6). Most patients had at least one comorbidity (189, 80.8%). Patient age (P = .04), dyspnea (P < .001), intensive care unit admission (P < .001), and mechanical ventilation (P < .001) were associated with increased mortality. Modifications of immunosuppressive therapy (P < .001), specifically the suspension of tacrolimus, maintained significance in multi-variable analysis. Conclusions. Attention to risk factors and the individualization of patient care, especially regarding immunosuppression management, is crucial for delivering more precise interventions to these individuals.

    Access to Liver Transplantation in Different ABO-Blood Groups and ""Exceptions Points"" in a Model for End-Stage Liver Disease Allocation System: A Brazilian Single-Center Study
    (2018) MARTINO, R. B.; WAISBERG, D. R.; DIAS, A. P. M.; INOUE, V. B. S.; ARANTES, R. M.; HADDAD, L. B. P.; ROCHA-SANTOS, V.; PINHEIRO, R. S. N.; NACIF, L. S.; D'ALBUQUERQUE, L. A. C.
    Background. In the Model for End-Stage Liver Disease (MELD) system, patients with ""MELD exceptions"" points may have unfair privilege in the competition for liver grafts. Furthermore, organ distribution following identical ABO blood types may also result in unjust organ allocation. The aim of this study was to investigate access to liver transplantation in a tertiary Brazilian center, regarding ""MELD exceptions"" situations and among ABO-blood groups. Methods. A total of 465 adult patients on the liver waitlist from August 2015 to August 2016 were followed up until August 2017. Patients were divided into groups according to ABO-blood type and presence of ""exceptions points."" Results. No differences in outcomes were observed among ABO-blood groups. However, patients from B and AB blood types spent less time on the list than patients from A and O groups (median, 46, 176, 415, and 401 days, respectively; P=.03). ""Exceptions points"" were granted for 141 patients (30.1%), hepatocellular carcinoma being the most common reason (52.4%). Patients with ""exceptions points"" showed higher transplantation rate, lower mortality on the list, and lower delta-MELD than non-exceptions patients (56.7% vs 19.1% [P<.01]; 18.4% vs 38.5% [P<.01], and 2.0 +/- 2.6 vs 6.9 +/- 7.0 [P<.01], respectively). Patients with refractory ascites had a higher mortality rate than those with other ""exceptions"" or without (48%). Conclusions. The MELD system provides equal access to liver transplantation among ABO-blood types, despite shorter time on the waitlist for AB and B groups. The current MELD exception system provides advantages for candidates with ""exception points,"" resulting in superior outcomes compared with those without exceptions.
