RESUMO

INTRODUCTION: Post liver transplantation (LT) patients endure high morbidity rate of multi-organ ischemic symptoms following reperfusion. We hypothesize that enhanced external counterpulsation (EECP) as a typical non-invasive assisted circulation procedure, which can efficiently inhibit the relative ischemic symptoms via the systemic improvement of hemodynamics. CASE PRESENTATION: A 51-year-old male patient, 76 kg, 172 cm, received orthotopic LT surgery for viral hepatitis B induced acute-on-chronic liver failure hepatic failure. His medical records revealed ischemic symptoms in multi-organ at the time of hospital discharge, including headache, refractory insomnia, abdominal paralysis, and lower limb pain. The EECP treatment was introduced for assisted rehabilitation and to improve the postoperative quality of life. Doppler Ultrasound examination showed significant augmentation of blood flow volume in the carotid arteries, the hepatic artery, the portal vein and the femoral artery during EECP intervention. A standard 35-hour EECP treatment led to significant improvement in quality of life, e.g. sleep quality and walking ability. CONCLUSION: We report a case of multi-organ ischemic symptoms in a post LT patient. EECP treatment can significantly improve the quality of life via the systematic promotion of hemodynamics.

RESUMO

BACKGROUND: The outcomes after liver transplantation have greatly improved, which has resulted in greater focus on improving non-hepatic outcomes of liver transplantation. The present study aimed to evaluate thoracic spine radio density in children and adolescents after liver transplantation. METHODS: A total of 116 patients who underwent living donor liver transplantation were retrospectively analyzed. The radio density at the eleventh thoracic vertebra was measured using computed tomography scan performed preoperatively then annually for 5 years postoperatively and subsequently every 2 or 3 years. RESULTS: The mean thoracic radio density of male recipients of male grafts had the lowest values during the study. The radio density of patients receiving a graft from a female donor was higher than in recipients with grafts from males. Total mean radio density decreased for first 5 years postoperatively and then increased. Changes in radio density were equally distributed in both steroid withdrawal and no steroid withdrawal groups for 5 years, after which patients with steroid withdrawal had a greater increase. Changes in radio density were equally distributed in both the steroid withdrawal and no steroid withdrawal groups up to age 20, after which patients in the steroid withdrawal group had a greater increase. CONCLUSIONS: Gender differences may affect the outcome of radio density changes after transplantation. Given the moderate association between thoracic radio density and bone mineral density in skeletally mature adults and further studies are needed to validate this relationship between thoracic radio density and bone mineral density changes in pediatric liver transplantation.

RESUMO

BACKGROUND: Glycogen storage disease (GSD) is a disease caused by excessive deposition of glycogen in tissues due to genetic disorders in glycogen metabolism. Glycogen storage disease type I (GSD-I) is also known as VonGeirk disease and glucose-6-phosphatase deficiency. This disease is inherited in an autosomal recessive manner, and both sexes can be affected. The main symptoms include hypoglycaemia, hepatomegaly, acidosis, hyperlipidaemia, hyperuricaemia, hyperlactataemia, coagulopathy and developmental delay. CASE PRESENTATION: Here, we present the case of a 13-year-old female patient with GSD Ia complicated with multiple inflammatory hepatic adenomas. She presented to the hospital with hepatomegaly, hypoglycaemia, and epistaxis. By clinical manifestations and imaging and laboratory examinations, we suspected that the patient suffered from GSD I. Finally, the diagnosis was confirmed by liver pathology and whole-exome sequencing (WES). WES revealed a synonymous mutation, c.648 G > T (p.L216 = , NM_000151.4), in exon 5 and a frameshift mutation, c.262delG (p.Val88Phefs*14, NM_000151.4), in exon 2 of the G6PC gene. According to the pedigree analysis results of first-generation sequencing, heterozygous mutations of c.648 G > T and c.262delG were obtained from the patient's father and mother. Liver pathology revealed that the solid nodules were hepatocellular hyperplastic lesions, and immunohistochemical (IHC) results revealed positive expression of CD34 (incomplete vascularization), liver fatty acid binding protein (L-FABP) and C-reactive protein (CRP) in nodule hepatocytes and negative expression of ß-catenin and glutamine synthetase (GS). These findings suggest multiple inflammatory hepatocellular adenomas. PAS-stained peripheral hepatocytes that were mostly digested by PAS-D were strongly positive. This patient was finally diagnosed with GSD-Ia complicated with multiple inflammatory hepatic adenomas, briefly treated with nutritional therapy after diagnosis and then underwent living-donor liver allotransplantation. After 14 months of follow-up, the patient recovered well, liver function and blood glucose levels remained normal, and no complications occurred. CONCLUSION: The patient was diagnosed with GSD-Ia combined with multiple inflammatory hepatic adenomas and received liver transplant treatment. For childhood patients who present with hepatomegaly, growth retardation, and laboratory test abnormalities, including hypoglycaemia, hyperuricaemia, and hyperlipidaemia, a diagnosis of GSD should be considered. Gene sequencing and liver pathology play important roles in the diagnosis and typing of GSD.

RESUMO

A combined heart+liver transplant is the only option for survival in some patients with end-stage combined cardiac and hepatic disease. These patients may suffer from congenital or acquired cardiac disease. The potential aetiologies of the associated hepatic disease are heterogeneous and include systemic disease that impacts the liver as well as venous congestion in patients with functionally univentricular circulation. In the latter scenario, patients with functionally univentricular circulation often require complex cardiac reconstruction in the setting of a cardiac transplant after staged palliation. During cardiac procurement, our approach is to dissect the entire ascending aorta and aortic arch in continuity; the entire superior caval vein and innominate vein in continuity; and the pulmonary arteries from hilum to hilum if the donor is not a candidate for recovery of the lungs. The cardiac and abdominal organ procurement teams work in parallel during dissection and combined en bloc cardio-hepatectomy. This technique minimizes exposure of both organs to cold ischaemia. This video tutorial demonstrates the key steps for combined en bloc heart+liver organ procurement.

RESUMO

BACKGROUND: Liver transplantation (LT) has been shown to be superior to resection in highly selected patients with perihilar cholangiocarcinoma (CCA), yet has traditionally been contraindicated for intrahepatic CCA (iCCA). Herein, we aimed to examine contemporary trends and outcomes for surgical resection and LT for iCCA. METHODS: The National Cancer Database was queried for patients presenting with stage I-III iCCA between 2010 and 2018 who underwent resection or LT. Overall survival (OS) was compared with Kaplan-Meier and multivariable Cox proportional hazards methods stratified by management. Secondary analysis of patients undergoing transplant for CCA was performed with the United Network for Organ Sharing database. RESULTS: Of 2565 patients, 2412 (94.0%) underwent resection and 153 (5.96%) LT of whom 84 (54.9%) received neoadjuvant therapy. Utilization of LT remained between 3.9% and 7.8% annually. Unadjusted 5-year OS was higher for LT than resection (59.8% vs 39.9%, P = .0067), yet adjusted analysis revealed no significant difference in mortality (hazard ratio, 0.91; 95% CI, 0.66-1.27; P = .58). On secondary analysis including 437 patients with all subtypes of CCA, unadjusted 5-year OS was higher for non-CCA indications (79% vs 52%-54%, P < .001). CONCLUSION: Utilization of LT for iCCA remains low and many cases are likely incidental. Although partial hepatectomy remains the standard of care for patients with resectable disease, our findings suggest that highly selected patients with unresectable iCCA may achieve favorable outcomes after LT. Granular, prospective data are needed to identify patients most likely to benefit from transplant and allocate scarce liver grafts.

RESUMO

BACKGROUND: Long-term medical and quality of life (QOL) outcomes in voluntary liver donors remain under investigated. The objective of the current study was to report long-term medical outcomes and re-evaluate QOL in living liver donors. METHODS: This was a single-center retrospective cohort study of donors who underwent donor hepatectomy between 2012 and 2018. We investigated long-term outcomes in 7 domains. These include medical problems, surgical procedures, work-related issues, pregnancy outcomes, psychiatric interventions, willingness to donate again, and long-term mortality. QOL was evaluated using short-form 36. RESULTS: The median follow-up time was 61.4 months (53.3-83.7). Among 698 donors, 80 (11.5%) experienced medical problems, 4 (0.6%) had work-related issues, and 20 (2.9%) needed psychiatric assistance. Surgery was performed in 49 donors (7%), and females were more likely to have undergone incisional hernia repair (5.8% vs 1.9%, P = .006). There were 79 postdonation pregnancies including 41 normal vaginal deliveries (51.9%), 35 cesarean sections (44.3%), and 3 miscarriages (3.8%). Willingness to donate again was reported by 658 donors (94.3%). Donors whose recipients were alive were more likely to donate again (95.5% vs 90.5%, P = .01). There were 3 deaths (0.4%) in the long-term. The mean physical composite score at initial and follow-up evaluation was 86.7 ± 13.9 and 76.5 ± 20.9 (P = .001), and the mean mental composite score at initial and follow-up evaluation was 92.1 ± 13.5 and 80.7 ± 16 (P = .001). CONCLUSION: The overall long-term outlook in living liver donors is promising. QOL parameters might deteriorate over time and frequent re-evaluation might be considered.

RESUMO

BACKGROUND: Portal hypertension (PHT) has been proven to be closely related to the development of hepatocellular carcinoma (HCC). Whether PHT before liver transplantation (LT) will affect the recurrence of HCC is not clear. METHODS: 110 patients with depressurization of the portal vein (DPV) operations (Transjugular Intrahepatic Portosystemic Shunt-TIPS, surgical portosystemic shunt or/and splenectomy) before LT from a HCC LT cohort, matched with 330 preoperative non-DPV patients; this constituted a nested case-control study. Subgroup analysis was based on the order of DPV before or after the occurrence of HCC. RESULTS: The incidence of acute kidney injury and intra-abdominal bleeding after LT in the DPV group was significantly higher than that in non-DPV group. The 5-year survival rates in the DPV and non-DPV group were 83.4% and 82.7% respectively (P = 0.930). In subgroup analysis, patients in the DPV prior to HCC subgroup may have a lower recurrence rate (4.7% vs.16.8%, P = 0.045) and a higher tumor free survival rate (88.9% vs.74.4%, P = 0.044) after LT under the up-to-date TNMI-II stage, while in TNM III stage, there was no difference for DPV prior to HCC subgroup compared with the DPV after HCC subgroup or the non-DPV group. CONCLUSION: Compared with DPV after HCC, DPV treatment before HCC can reduce the recurrence rate of HCC after early transplantation (TNM I-II). DPV before LT can reduce the recurrence of early HCC.

RESUMO

OBJECTIVE: Aim: to review information resources and analysis of the own experience on this problem for the provision of modern knowledge in the pathogenesis of the pathology, the latest diagnostic and treatment technologies, with consideration of the need to adhere to a single strategy in the management of patients with BA. PATIENTS AND METHODS: Materials and Methods: The analysis of the data regarding the results of existing studies evaluating the clinical benefit and safety of diagnostic and treatment methods in Biliary atresia. CONCLUSION: Conclusions: BA is the leading cause of neonatal cholestasis development. Early diagnostics of BA, based on the complex evaluation of clinical-laboratory, instrumental and morphological signs of the pathology, has a significant meaning. Surgical correction during the first 2 months of life - the Kasai procedure, as well as dynamic post-surgery follow-up significantly prolong the life of children and allow postponing liver transplantation. The highest patient survival both at the first stage of treatment - conduction of the Kasai procedure and the stage of liver transplantation may be achieved by joined work of surgeons and pediatricians, which allows considering the whole row of possible problems.

RESUMO

Cholangiocarcinoma is the second most common primary hepatic neoplasm, accounting for 10% to 20% of primary liver tumors and 3% of all gastrointestinal neoplasms. The 3 anatomic types (intrahepatic, perihilar, and distal) have distinct epidemiologies, etiopathogenesis, and clinical outcomes. Surgical resection remains the current standard of treatment, but outcomes remain poor. With the continued expansion of liver transplant programs, use of liver transplant for malignant indications has also increased, with reports of encouraging outcomes. However, given the scarcity of livers fortransplant and accompanying possible complications, liver transplant for treatment of patients with cholangiocarcinomas remains experimental in most of the world. We reviewed the existing literature on treatment modalities for cholangiocarcinoma with emphasis on the pros and cons of surgical resection and indications, protocols, and outcomes of liver transplant as a treatment modality for patients with cholangiocarcinoma.

RESUMO

Monitoring Epstein-Barr virus (EBV) and cytomegalovirus (CMV) infection after transplantation is recommended to enable preemptive therapy. However, the most suitable sample type remains unclear. Patients who underwent hematopoietic stem cell or liver transplantation were included in this study. Viral loads in sequential whole-blood and plasma samples were retrospectively analyzed. EBV DNA was detected more frequently in whole blood (55%) than in plasma (18%). The detection rate of CMV DNA was similar between the two sample types. The correlation of viral loads between the two sample types were 0.515 and 0.688 for EBV and CMV, respectively. Among paired samples in which EBV DNA was detected in whole blood, the plasma EBV detection rate was significantly higher in patients who underwent hematopoietic stem cell transplantation than in those who underwent liver transplantation. The viral DNA load in whole blood and plasma showed similar trends. The EBV detection rate was higher in whole blood, and a high correlation was observed between CMV DNA loads and whole blood and plasma. These results indicate that whole blood is more sensitive for monitoring both EBV and CMV, whereas plasma is a potential alternative sample for monitoring CMV.

RESUMO

OBJECTIVES: Bronchiectasis is characterized by abnormal, persistent, and irreversible enlargement of the bronchi. Many etiological factors have been described, but there are limited data on the development of bronchiectasis after organ transplantation. Our study is the first to study evaluate the frequency of bronchiectasis in heart and liver transplants as well as kidney transplants. Our aim is to analyze the frequency of bronchiectasis development after solid-organ transplant and the characteristics of the cases and to evaluate potential relationships. MATERIALS AND METHODS: We retrospectively analyzed data of patients who underwent solid-organ transplant at the Baskent University Faculty of Medicine Hospital through the hospital electronic information system. Demographic, clinical, and laboratory data and thoracic computed tomography scans were evaluated. RESULTS: The study included 468 patients (151 females/317 males). Kidney transplant was performed in 61.5% (n = 207), heart transplant in 20.3% (n = 95), and liver transplant in 18.2% (n = 85) of patients. Development of bronchiectasis was detected in only 13 patients (2.7%). We determined a 13.64-fold risk of developing bronchiectasis in patients with chronic obstructive pulmonary disease and 10.08-fold risk in patients with pneumonia by multivariate regression analyzes, in which all possible risk factors for the development of bronchiectasis after transplant were evaluated. CONCLUSIONS: The pathophysiology of transplantassociated bronchiectasis has not yet been clarified. Underlying diseases, recurrent pulmonary infections, and potential effects from immunosuppressive drugs may contribute to the pathogenesis of bronchiectasis. Further prospective studies are needed to include long-term health outcomes in transplant patients with and without bronchiectasis.

RESUMO

Biliary strictures afterlivertransplant are amenable to endoscopic dilatation or percutaneous dilatation and stenting in most cases. In rare cases, for recurrence or tight stricture, surgery is required, and hepaticojejunostomy is the favored procedure. We report a case of posttransplant stricture in a duct-to-duct anastomosis that could not be accessed due to prior gastric bypass. Despite multiple percutaneous transhepatic cholangiography dilatations, the stricture recurred, and the patient was taken up for bilioenteric bypass. During surgery, dense adhesions in the infracolic compartment with chronically twisted jejunal loops, due to prior mini gastric bypass, were encountered, which prevented the creation of a jejunal Roux limb. Hepaticoduodenostomy was performed with no recurrence of stricture at 12 months. Hepaticoduodenostomy is a viable option for surgical management of recurrent biliary strictures, especially in a setting of prior bariatric/diversion procedures.

RESUMO

OBJECTIVES: Splenectomy during liver transplant can affect platelet function. In this study, our primary aim was to assess the perioperative platelet function by rotational thromboelastometry and the effects of splenectomy on platelet function. MATERIALS AND METHODS: We studied 40 consecutive liver transplant recipients with end-stage liver disease (50% as a result of hepatitis C). Patients with splenectomy were compared with patients without splenectomy (n = 20/group). Three platelet function parameters by rotational thromboelastometry were studied: platelet activation with arachidonic acid, platelet activation with adenosine diphosphate, and platelet activation with thrombin receptor-activating peptide 6. Patients were monitored perioperatively and until postoperative day 21. Heparin was infused for 2 days postoperatively (60-180 U/kg/day), followed by administration of subcutaneous low-molecular-weight heparin (40 mg/24 h) on postoperative days 2 and 3 and oral acetylsalicylic acid when platelet count was >50 × 103/µL. RESULTS: Liver disease contributed to low perioperative platelet count and function. Patients showed significant improvement by postoperative day 14 and day 21, particularly after splenectomy. Platelet count was significantly correlated with the 3 platelet function parameters by rotational thromboelastometry (P < .001). Acetyl salicylic acid was required earlier (postoperative day 3) for patients with splenectomy (8/20) but only affected the platelet function represented by platelet activation with arachidonic acid, whereas other platelet activation pathways were less affected. Patients received no transfusions of platelet units. CONCLUSIONS: End-stage liver disease significantly contributed to low platelet function and counts before transplant. Two weeks were required for recovery of patients posttransplant, with further enhancement by splenectomy. Some recipients showed recovery that exceeded the normal reference range, which warranted monitoring. Acetyl salicylic acid only affected 1 platelet activation receptor.

RESUMO

Tigecycline is a parenteral glycycline antibiotic that is used to treat severe infections caused by susceptible organisms, butitis also associated with hepatotoxicity. We present 2 similar patients with hepatic steatosis possibly associated with early tigecycline after transplant. In the first case, a 61-year-old woman underwent liver transplant for acute severe hepatitis; 6 days posttransplant, because of nonroutine resistant fever, the patient received tigecycline combined with daptomycin. Retransplant was applied to the patient on day 12 posttransplant because of acute liver failure secondary to hepatic vein thrombosis. After retransplant, biochemical levels gradually increased, exceeding the upper limit of normal. In liver biopsy, the patient had macrovesicular steatosis in 70% to 80% ofthe parenchyma. In the second case, a 53-yearold woman underwent liver transplant for liver cirrhosis. Tigecycline was added to the treatment because of recurrent fever on day 6 after transplant, with treatment also comprising piperacillin-tazobactam and meropenem. On day 15 of the patient's tigecycline treatment, her liver function tests were elevated. In liver biopsy, the patient had 30% to 40% macrovesicular steatosis and canalicular cholestasis in the parenchyma, especially in zone 3. Reports of hepatic steatosis associated with early tigecycline after transplant are quite new to the literature.

RESUMO

Mucormycosis, a group of opportunistic mycoses caused by Mucorales, present a significant threat to immunocompromised patients. In this report, we present the case of a 57-year-old male patient who underwent liver transplant for secondary biliary cirrhosis following inadvertent bile duct injury. Despite initial satisfactory postoperative evolution, the patient developed fever, and imaging revealed a suspicious lesion. Preliminary culture growth suggested a filamentous fungus, leading to initiation of liposomal amphotericin B. However, the lesion progressed, and a surgical debridement was necessary. During surgery, involvement of the liver dome and diaphragm was observed, and a nonanatomical hepatectomy was performed. Despite efforts, the patient's condition deteriorated, ultimately resulting in multiple organ failure and mortality.

RESUMO

BACKGROUND AND AIM: Stress cardiomyopathy in donors can potentially affect graft function and longevity. This study aims to investigate the association between echocardiographic left ventricular ejection fraction (LVEF) < 50%, and/or the presence of left ventricular regional wall motion abnormalities (RWMA) in organ donors, and short- and long-term liver and kidney graft survival. Our secondary aim was to link graft survival with donor and recipient characteristics. METHODS: All donors considered for liver and kidney donation with echocardiographic records at Sahlgrenska University Hospital between 2006 and 2016 were matched with their recipients through the Scandiatransplant register. The studied outcomes were graft survival, re-transplantation, and recipient death. Kaplan-Meier curves were used to plot time to event. Multivariate Cox-regression was used to test independence. RESULTS: There were 370 liver donors and 312 kidney donors (matched with 458 recipients) with echocardiographic records at Sahlgrenska University Hospital between June 2006 and November 2016. Of patients with LV dysfunction by echocardiography, there were 102 liver- and 72 kidney donors. Univariate survival analyses showed no statistical difference in the short- and long-term graft survival from donors with LV dysfunction compared to donors without. Donor age > 65 years, recipient re-transplantation and recipient liver tumor were predictors of worse outcome in liver transplants (p < .05). Donor age > 65, donor hypertension, recipient re-transplantation, and a recipient diagnosis of diabetes or nephritis/glomerulonephritis had a negative association with graft survival in kidney transplants (p < .05). CONCLUSION: We found no significant association between donor LV dysfunction and short- and long-term graft survival in liver and kidney transplants, suggesting that livers and kidneys from such donors can be safely transplanted.

RESUMO

Homozygous familial hypercholesterolaemia is a life-threatening genetic condition, which causes extremely elevated LDL-C levels and atherosclerotic cardiovascular disease very early in life. It is vital to start effective lipid-lowering treatment from diagnosis onwards. Even with dietary and current multimodal pharmaceutical lipid-lowering therapies, LDL-C treatment goals cannot be achieved in many children. Lipoprotein apheresis is an extracorporeal lipid-lowering treatment, which is used for decades, lowering serum LDL-C levels by more than 70% directly after the treatment. Data on the use of lipoprotein apheresis in children with homozygous familial hypercholesterolaemia mainly consists of case-reports and case-series, precluding strong evidence-based guidelines. We present a consensus statement on lipoprotein apheresis in children based on the current available evidence and opinions from experts in lipoprotein apheresis from over the world. It comprises practical statements regarding the indication, methods, treatment goals and follow-up of lipoprotein apheresis in children with homozygous familial hypercholesterolaemia and on the role of lipoprotein(a) and liver transplantation.

RESUMO

Background and Objectives: The aim of this study is to evaluate the clinical and laboratory changes of ischemia and reperfusion injury in the remnant livers of donors with and without Pringle maneuver. Furthermore, we evaluated the recipients who have been transplanted with liver grafts from these donors. Methods and Materials: A total of 108 patients (54 living liver donors and 54 liver recipients) who underwent donor hepatectomy and recipients who living donor liver transplantation, were included in this randomized double-blind study between February 2021 and June 2021. The donors were divided into two groups: Pringle maneuver applied (n = 27) and Pringle maneuver not applied (n = 27). Similarly, recipients with implanted liver obtained from these donors were divided into two groups as the Pringle maneuver was performed (n = 27) and not performed (n = 27). Blood samples from donors and recipients were obtained on pre-operative, post-operative 0 h day (day of surgery), post-operative 1st day, post-operative 2nd day, post-operative 3rd day, post-operative 4th day, post-operative 5th day, and liver tissue was taken from the graft during the back table procedures. Liver function tests and complete blood count, coagulation tests, IL-1, IL-2, IL-6, TNF-α, and ß-galactosidase measurements, and histopathological findings were examined. Results: There was no statistically significant difference in the parameters of biochemical analyses for ischemia-reperfusion injury at all periods in the donors with and without the Pringle maneuver. Similarly, there was no statistically significant difference between in the recipients in who received liver grafts harvested with and without the Pringle maneuver. There was no statistically significant difference between the two recipient groups in terms of perioperative bleeding and early bile duct complications (p = 0.685). In the histopathological examinations, hepatocyte damage was significantly higher in the Pringle maneuver group (p = 0.001). Conclusions: Although the histological scoring of hepatocyte damage was found to be higher in the Pringle maneuver group, the Pringle maneuver did not augment ischemia-reperfusion injury in donors and recipients that was evaluated by clinical and laboratory analyses.
